Description

DEVICE AND MACHINE TO DELIVER THE ROAD FRONTAL MATERIAL WHEN Widening the Road

The invention relates to a device for transferring a road edge material when widening a road comprising a frame, attaching means fitted to a frame for attaching the device to a working machine operating the device, a plow attached to a frame for transferring peripheral material, the plow having a blade in the transverse direction as the machine moves forward, a substantially vertical and longitudinal support machine blade coupled with the transfer blade for transmitting the lateral force exerted by the transfer blade to a road edge, wherein said frame is disposed behind the transfer blade in the moving direction of the device.

The invention also relates to a work machine for moving the edge material of a road while widening the road.

Finland's current road network is largely based on roads that are still relatively old, built decades ago, for smaller roads such as main roads. However, over the years, vehicle sizes and traffic volumes have increased. As a result, Finland has a significant number of roads that are too narrow in relation to current needs and that need to be widened.

As the road is widened, at least partially inferior organic material at the edge of the road outside the carriageway and off-road shall be removed and replaced by road material used as the road body. This peripheral material is not suitable for road construction as the durability and bearing capacity of the road formed on the peripheral material would be inferior. Traditionally, the removal of the peripheral material has been accomplished using an excavator, which is slow and expensive.

The object of the invention is to provide a device with low manufacturing costs for moving the edge material of the road when widening the road, which enables the transfer of the edge material to be quick and cost effective. It is an object of the present invention to provide a machine tool at a manufacturing cost for transferring the peripheral material of the machine when widening the road, which enables the transfer of the peripheral material to be quick and cost effective. Features of the present invention will be apparent from the accompanying claim 5.

The object of the device according to the invention can be accomplished by a device for moving the road edge material when widening the road, which device includes a frame, fastening means adapted for attaching the device to a working machine using the device and a plow attached to the body for moving the edge material. The plow includes a transfer blade disposed at an angle to the longitudinal direction of the implement to move the peripheral material as the implement moves forward and a substantially vertical and longitudinal support blade coupled to the lateral force exerted by the transfer blade to the road edge. The body is arranged in the direction of travel of the device behind the transfer blade to support the transfer blade and also extend to the side of the support blade to support the support blade. With the device according to the invention, the transfer of the road edge material can be performed as a continuous operation as the implement moves continuously along the road. The operation of the device according to the invention is based on the fact that when driving a work machine along a road, the device preferably positioned on the side of the road is pressed against the edge of the road by the machine, receiving the plow laterally from the road . The frame on the back and side of the plow enables the transmission of forces to the implement via attachment means. The transfer blade plows the edge material in the direction of the road ditch as the machine travels to the implement on a road.

Preferably, the fastening means are arranged to fasten the device to the work machine so that the device passes outside the machine line, at the side of the line. This can be achieved by means of fastening means fitted to the side of the plow, which enable the device to be mounted, for example, on the side of a tool. Alternatively, this can also be achieved by means of fastening means which enable the device to be towed, for example, to the towing hook of the implement outside the driving line of the implement.

Preferably, the body is fixedly fixed directly to the support blade and the transfer blade. This makes the device very rigid, durable and simple.

The body may include vertical rails and a carriage mounted on said vertical rails to which the plow is attached, and an actuator articulated between the carriage and the body to provide vertical plow height adjustment by moving the carriage with rails. With the help of guides and a carriage, the depth of the trench produced by the device can be varied steplessly.

Alternatively, the device may be adapted to be attached to the rear of the implement, but in this case the implement may need to be driven partially over the edge material.

The body of the device may include wheels to support the device against the ground. With wheels, the working depth of the machine can be kept constant despite the vertical movements of the implement.

The angle between the transfer blade and the support blade may be 135-160 °, preferably 145-155 °. In this case, the device produces a sufficiently wide trench, but on the other hand does not cause unreasonable resistance to the longitudinal travel of the machine, which would be caused, for example, by a plow near a rectangle.

Preferably, the transfer blade of the device has a width perpendicular to the plane of the support blade of 0.3 to 1.0 m. In this case, the resulting resistance to the machine is reasonable.

According to one embodiment, the device comprises a vertical joint between the transfer blade and the support blade and another actuator articulated between the transfer blade and the support blade to change the angle between the transfer blade and the support blade. The joint and actuator can be used to adjust the angle between the transfer blade and the support blade to the desired trench width or to avoid large stones, for example.

Preferably, the actuator is a hydraulic actuator. In this case, the angle adjustment between the transfer blade and the support blade can be made, for example, from the implement cab.

Alternatively, the actuator may be mechanical. The mechanical implementation is inexpensive to implement, but requires user action to change the angle between the transfer blade and the support blade.

Alternatively, the transfer blade and support blade are fixed to each other. Such an embodiment is very durable and inexpensive to manufacture.

According to one embodiment, the fastening means are bolt-fastening means for securing the device to the side of the bucket of a work machine. The bolt attachment means are very inexpensive to manufacture and can be mounted directly to the side of a wheel loader bucket, for example.

According to another embodiment, the fastening means are quick-fastening means for fastening the device to the quick-fastening means of the working boom. The quick attachment means allow the device to be quickly replaced at the end of the work boom, just like a bucket. In addition, the device is easily accessible with various implements without modifications to the implement.

The device according to the invention is adapted to be used and pushed or retracted by means of a work machine and is thus only an auxiliary device, not a self-propelled machine.

In the device according to the invention, the suspension means receive forces in several different directions. The hanging means receives the vertical forces exerted on it when the device is pressed against the peripheral material. The suspension means also receives the longitudinal forces of the road and the transverse forces of the plow caused by the frictional material and the working machine. At the same time, the suspension means are subjected to a torque created when the plow is at a distance from the suspension means supported on the body.

The purpose of a working machine according to the invention can be achieved by a working machine for moving the road edge material when widening the road, which includes a frame, wheels with a bearing on the frame and suspension means hinged to the frame to attach the tool. Further, the implement comprises actuators for adjusting the distance between the tool and the frame by moving the attachment means by moving the attachment means, and a device according to one of the above embodiments suspended by means of the attachment means for moving the road edge material. With such a machine, moving the edge material of the road can be performed as a continuous operation while driving the machine along the road. Thus, work is not a batch work or interruption like work on an excavator whose capacity is limited by the capacity of the excavator bucket. On the other hand, the implement according to the invention is advantageously formed from existing implements, because the device to be added to the implement for moving the edge of the road is inexpensive and simple.

Preferably, the implement is a Wheel Loader with a bucket to which the device is attached as a tool by means of suspension means. This results in a low-cost, efficient machine for use in road widening.

Preferably, the device is attached to the side of the bucket. This allows the wheel loader to be driven on the paved part of the road.

The device of the invention can be used by a method of widening a road, which removes edge material from the road edge at a selected depth outside the road to form a trench along the road using a machine to unlock the edge by pushing the device against the edge using a machine tool. In addition, the road edge material is plowed away from the road to form a trench, and the trench is filled with new road material. By such a method, a road edge material unsuitable for road widening can be shifted aside from the roadway of the new road material in a fast and inexpensive continuous process.

Preferably, the device is pressed downwardly into the peripheral material by a machine tool. In this case, the device makes a trench with a uniform depth.

Preferably, the device according to the invention is used to widen roads which include a ditch or ramp. There is thus room for the peripheral material to move aside.

Preferably, the transfer of the peripheral material is made outside the road surface. This eliminates the need for the device to break the coating.

The invention will now be described in detail with reference to the accompanying drawings, in which:

Figure 1 is a side view of the implement and device according to the invention, Figure 2 is a top view of the embodiment of Figure 1,

Figure 3 is a front view of the embodiment of Figure 1,

Figure 4 shows the step of operating the device according to the invention in which the trench is filled with new road material,

Figure 5 illustrates the step of operating the device of the invention in which the new road material is coated.

Figures 1-3 show a preferred embodiment of the device 10 and the machine 100 according to the invention. In this embodiment, the implement 100 of the invention is a Wheel Loader 116, which may be a commonly used wheel loader known in the art. Wheel loader 116 includes frame 102, wheels 104 mounted on frame 102, suspension means 106 articulated to frame 102 for securing tool 108, and actuators 114 for adjusting distance between tool 108 and ground 102 by moving suspension means 106. In this case, the suspension means 106 are preferably a working boom 112 articulated at one end to the body 102 of the wheel loader 116, actuated 114 by lifting cylinders 115 articulated between the body 12 and the working boom 112 of the wheel loader 116. 10 may be attached directly to the side of bucket 110. For attaching the device to the bucket, openings for bolt attachment or other suitable attachment may be provided. The bucket should preferably have a side wall to which the attachment is made.

The device 10 according to the invention includes a body 12 and fastening means 14 fitted to the body 12 for attaching the device 10 to a working machine 100 using the device 10, preferably to the side of the working machine 100. The body 12 may be made, for example, as a beam structure comprising a one or two-piece rear beam 40 as shown in Figure 2 and a front beam 44 in its forward direction in the direction of travel of the device 10. The front beam 44 and rear beam 40 are preferably secured to fastening means 14 fastening flange 46. The function of the body 12 is to support the plow 16 attached thereto which pushes the road edge material 2 aside when the device 10 is used. The device 10 can be attached, for example, to the side of the bucket 110, for example by means of bolt fastening means 48, as shown in Fig.

The plow 16, in turn, comprises a transfer blade 18 and a support blade 20 arranged at an angle with respect to each other and mounted on a body 12 disposed behind both the transfer blade 18 and the side of the support blade 20. The transfer blade 18 is preferably fixedly fixed to the body 12 so that the mutual position of the body and the transfer blade 18 is locked. The function of the transfer blade 18 is to transfer the edge material 2 to the side ramp 7 or ditch adjacent the road 1 as the machine 100 moves forward, whereas the support blade 20 serves to transfer the lateral force exerted by the transfer blade 18 More specifically, when moving the device 10 according to the invention by means of a working machine 100, the longitudinal support blade 20 cuts the peripheral material 2 of the edge 1 of the road 1. The transfer blade 18 connected to the support blade 20 is at an angle α to the working blade 20. transmits the forward force of the working machine 100 to the peripheral material 2, converting the component of the force mainly in the transverse direction of the road 1. The support blade 20, in turn, partially receives this counterforce of the transverse force of the road 1, transferring it to the edge 3 of the road 1. Preferably the support blade 20 is a vertical plate-like structure transfer of material to the side. Preferably, the transfer blade 18 is curved as shown in Figs.

Preferably, both the support blade and the transfer blades are steel structures, which may include separate tread forming portions. The tread portions may be, for example, welded or bolted to the transfer blade and support blade. When transferring the edging material, which may be partially crushed, the support blade and transfer blade of the device will be subjected to heavy wear. Therefore, the treads are preferably of wear steel, such as hard steel marketed under the Hardox 400 brand name or of higher strength.

There may be a vertical joint between the support blade and the transfer blade, which allows the angle between the support blade and the transfer blade to be changed either during or even during work. If the angle is to be actively altered during work, an actuator, such as a hydraulic cylinder, must be provided between the support blade and the transfer blade, which allows the angle between the support blade and the transfer blade to be changed. On the other hand, if it is desired to change the angle only between jobs, there may be a mechanical locking mechanism between the support blade and the transfer blade to lock the desired angle between the support blade and the transfer blade during operation. The angle between the transfer blade and the support blade, which is also the same as the angle between the transfer blade and the direction of travel of the device, can be varied between 135-160 °, preferably 145-155 °, to achieve a sufficiently large recess width. By changing the angle, the width of the recess is also changed. The larger the angle, the wider the recess is formed and the greater the resistance of the device to the progress of the implement. At its simplest, the transfer blade and support blade may be fixedly fixed to each other at a fixed angle.

In the embodiment of the device shown in Figs. 1-3, the transfer blade 18 is secured to the extension of the support blade 20 in the direction of travel of the working machine 100, but it should be understood that the support blade may also be attached alongside the transfer blade. In this case, the forward edges of the transfer blade and the support blade depart from the same point as the blades extend backward.

The fastening means used in the device may also be such that, instead of a fixed flange, they can be moved to adjust the depth of the trench formed vertically. In such an embodiment there may be a carriage and guides between the mounting flange and the frame and an actuator therebetween. The actuator allows the carriage to be moved with guides to provide a plow height adjustment. For example, the frame can be fixed to the carriage and the rails to the mounting flange or vice versa.

According to the embodiment of Figure 3, the transfer blade 18 and the support blade 20 may be provided with guides 50 through which they engage the carriage 12 of carriage 12. The carriage 52 and the guides 50 may be movable relative to one another by actuator 54 to adjust the working depth.

When implementing the device according to the invention, a working machine, such as Wheel Loader 116 according to Figures 1-3, preferably moves on pavement 6 of paved road 1 near edge 3 of road 1. The pavement 6 ends near the edge 3 of the road 1, from where a short strip of peripheral material 2 begins, ending in a ditch 5 or a ramp 7 adjacent to the road 1. The purpose of the device is to move the peripheral material 2 away from the road 1 pavement towards the ditch 5 or ramp 7, leaving a recess 4 of rectangular cross-section adjacent the pavement 6 of the road 1 to move the peripheral material 2 such that the transfer is initiated by lowering the device 10 supported on the hanging means 106 of the working machine 100 against the peripheral material 2. The device 10 is pressed by the actuators 114 of the attachment means 106 of the working machine 100 to the peripheral material 2 while the working machine 100 moves forward, the plow 16 sinks into the peripheral material 2. As the working machine 100 moves forward along the pavement 6 of the road 1, away from material 2 on the cover 6, with the support blade 20 of the plow 16 resting on the body of the remainder of the road 1 towards the center of the road 1. The support blade 20 keeps the plow 16 in a substantially straight direction, so that only slight lateral force is exerted on the machine 100, which tends to turn the machine 100 away from the edge 3 of the road 1. The plow 16 may be shaped so as to tend to sink deeper into the peripheral material 2, whereby the actuators 114 of the attachment means 106 of the machine 100 prevent the change of depth of the trench. This design makes it easier to start a trench when the machine is less resistant to pressing it into the periphery 2.

Once the trench 4 has been formed, the trench can be filled with new road material 8, as shown in Figure 4, whereby the road bearing frame widens by the width of the trench 4. The new widened road frame can then be either completely or, for widening only, covered by a new pavement 9 as shown in Figure 5. The device according to the invention can be used advantageously for widening paved roads, but also for widening uncoated roads.

According to one embodiment, the fastening means for attaching the device to the implement may also be quick-attach means known from buckets, for example, which could be used to attach the device directly to the attachment means of the implement instead of the tool. This would reduce the weight of the implement without, for example, having to carry an extra bucket. On the other hand, connecting the machine to a work machine would be greatly facilitated.

The plow of the device according to the invention may be about 1.0 to 2.0 m long, 0.5 to 1.5 m high, and adjustable in width from 0.3 to 1.0 m in the direction of the working machine. The support blade may be quite short in length. , only about 0.3-0.6 m, while the length of the transfer blade from the joint between the support blade and the transfer blade to the other end may be 1.5-2.0 m with the transfer blade at an angle to the working direction of the machine. Preferably, the trench formed by the device according to the invention has a depth of 0.3 to 1.0 m.

The implement of the invention may be, for example, a wheel loader, a tractor or a truck, but most preferably a wheel loader because it has a working boom and its actuating cylinders which act as suspension means and actuators for the implement of the invention.
