Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for repairing road surfaces, particularly asphalt road surfaces, and relates to a wheeled chassis equipped with cutters or cutting devices for removing old road surfaces, and a front end of the chassis that is placed on a new road surface. The present invention relates to an apparatus having a coating device arranged in a container and connected by a conveying device with a supply container, such as a tank, containing fresh surface material.

Known machines of this type with supply containers have relatively small holding containers in order to reduce the overall size of the machine. As a result, the truck carrying the new surface material must continue to move in front of and close to the machine during operation of the machine. Furthermore, residual amounts in the supply container are difficult to remove from the supply container. Furthermore, a disadvantage of the known machine is that the front axle of the machine is subjected to uneven loads during the coating operation, due to the fixed relationship of the supply container with the chassis, when the supply container is freshly filled. , the load acting on the shaft is several times greater than that of an empty supply container. Thus, since the cutting device is located on the chassis, different depths of cut result.

The object of the invention is to provide a device for road surface repair which solves the above-mentioned problems, in which the supply container has as large a capacity as possible;
easily fillable and easily emptied and supplied to the chassis in such a way that uneven loads on the machine can be eliminated or at least substantially reduced when filled and emptied. It is something.

The present invention is an apparatus for repairing road surfaces, particularly asphalt roads, and includes a wheeled chassis equipped with cutters or cutting devices for removing old road surfaces, and a chassis for supplying new pavement material onto new road surfaces. It has a supply container, such as a tank for storing new paving material located at the front end, and a coating device connected via a conveying device, the supply container being provided with supporting wheels and extending transversely to the direction of movement of the device. A road surface repair device is provided that is rotatably mounted on a chassis for pivoting about an elongated horizontal axis.

It is therefore possible in a machine according to the invention to have a supply container of relatively large capacity, such that when the supply container is not in use, it can be pivoted into a position without undesirably increasing the overall dimensions of the machine. The pivotable pivotable connection of the supply container to the chassis makes it possible to remove residual quantities from the supply container without creating difficulties in cleaning the supply container. Finally, by the provision of supporting wheels of the supply container and the indirect connection of the supply container to the chassis,
A change in the filling amount of the supply container causes little change in the load on the chassis. However, it is also possible, on the other hand, to increase the load on the pair of chassis support wheels adjacent to the supply container by shaking the supply container, which may be desirable, for example, if a hard and difficult-to-treat road surface has to be removed. It can be done.

In one embodiment of the machine of the invention, the supply container is rotatably connected directly to the chassis. Therefore, it is appropriate to attach the supply container to one end of a support frame forming part of the transport device, and to rotatably attach the other end of the support frame to the chassis.
This has the advantage that the supply container can be filled and emptied particularly easily.

At least one hydraulic actuator is mounted for pivoting the supply container. A particular advantage of this configuration is that the hydraulic actuator can be connected to an effective hydraulic system. In the preferred construction, hydraulically actuated cylinders are disposed on opposite sides of the support frame, one end of the cylinder being pivotally connected to the chassis and the other end thereof being rotatable to the support frame at a point between the horizontal axis and the supply container. movably connected. Such a structure constitutes a high mechanical load capacity.

The number of support wheels attached to the supply container can be chosen freely. The provision of two support wheels has been shown to be adequate. In the preferred construction, the support ring is at the lower end of the vertically adjustable leg. This allows the supply container to be placed in different up and down positions without increasing load fluctuations on the chassis.
Fully hydraulically actuated cylinders allow for swivel movement, as well as easy height adjustment via length-adjustable legs with support wheels. Hydraulically adjusting length legs is a proven advantage.

Embodiments of the present invention will be described with reference to the drawings. The figure is a schematic side view of an embodiment of the road repair machine of the present invention.

Referring to the figure, the machine has a pair of driveable and steerable front wheels 2 and a pair of rear wheels 3. The drive motor 4 is supported behind the chassis and the driver's seat 5 is in front of the motor 4. The seat 5 on the chassis 1 has a fuel tank 6 in front that communicates with the motor 4, a liquid container 7 in front of the tank 6, and the container 7 is attached to the underside of the chassis 1 behind the pair of front wheels 2. operably connected to a heating device 8. After the heating device 8 there is a cutting or cutting device 9 with a cutting or cutting roll 10 . At the rear end of the machine there is a coating device 11 which is connected via a conveying device 12 consisting of two belt conveyors 13 and 14 to a supply container 15 located at the front of the machine. The old road surface is cut by a cutting device 9, and the scraped old pavement material is removed to the side of the road by a warm conveyor, rotating brush, etc. (not shown), or is filled into the depressions remaining on the road surface after cutting. reused for.

The supply container 15 is rotatably connected to one end of a support frame 16, and the other end of the support frame 16 is rotatably connected to the chassis 1 so as to pivot around an axis 17. To enable pivoting movement of the support frame 16, the rollers of the belt conveyor 14 are mounted within the support frame 16, and on both sides of the frame there are hydraulically actuated cylinders rotatably connected to the chassis 1 at one end and to the support frame 16 at the other end. 18 is installed.

The supply container 15 is supported by wheels 19 on the road surface 20 for normal positioning. Each of the two legs on which the wheels 19 are attached are vertically adjustable by hydraulically actuated cylinders 21, so that the supply container 15
Not only can the height position of the road surface 20 be varied up and down due to the operation of both operation cylinders 18 and 21, but also the operation of the operation cylinder 18 moves the vehicle to a position where its entire weight acts on the pair of adjacent front wheels 2. It can be arranged to be moved.
