DESCRIPTION

Tracked vehicle with universal crane

The invention relates to a tracked vehicle equipped with a crane. In particular, the invention relates to a military tracked vehicle, such as Armored recovery vehicles or Armored engineer vehicles, which can be equipped with a crane as a recovery crane.

DE 10 2006 034 688 Al an Armored support vehicle comprising the features of the preamble of claim 1, which is characterized by the fact that it can be upgraded or converted for different tasks such as a recovery, bridge-laying, pioneer and mine-clearing vehicle, for which purpose it has a common modular vehicle chassis. This vehicle chassis is used to accommodate the various — tools required to perform the different tasks.

AT 004 275 Ul relates to a vehicle for firefighting and rescue services. In an advantageous embodiment, a collapsible searchlight is attached to the roof of the vehicle, which can be moved at an angle of 340°.

DD 281 935 A3 deals with a basic vehicle that has been converted into an armored recovery vehicle. For this purpose, a support welded from two tubes is movably attached. A square is welded to the upper end, to which a bracket is attached to hold the water recovery rope and the tensioning ropes.

DE 20 2013 102 281 U1 discloses a winch with a monitoring device. This device is intended to prevent the pulling means from being pulled in too far,

even if the pulling means does not run vertically. This prevents damage to the rope or the hook or other slinging means.

DE 812 980 U1 discloses a recovery vehicle with a main lifting device and a slewing crane supported on the vehicle. A mechanical connection is provided between the main lifting device, which is designed as a main extension arm, and the crane extension arm, which connects the main lifting device to the crane extension arm for lifting the main lifting device with the crane extension arm. This creates a recovery vehicle with jib crane lifting characteristics and the possibility of supported or suspended towing, but only one or two hydraulic cylinders are required to lift the crane extension arm and the main extension arm.

DE 791 792 111 describes a mobile crane with a telescopic extension arm — pivotably articulated on a rotatable superstructure with a lift rope.

DE 36 13 603 Al discusses the creation of a multi-purpose recovery vehicle with a chassis mounted on wheels, a slewing crane arranged on the chassis and a recovery device arranged at the rear end of the chassis.

DE 20 2009 005 446 111 proposes a mobile crane with a single-cab solution for Ferry and crane operation. For this purpose, the driver's cab can be pivoted in an opposite direction to the jib head and can be detachably connected to an undercarriage of the crane in a travel position with an opposite viewing angle to the jib head for road travel.

DE 10 2006 034 688 Al shows a universal support vehicle for combinable tasks of a recovery, bridge-laying, pioneer and/or mine-clearing vehicle,

comprising a common modular chassis for accommodating the chassis components, the engine modules and at least one fuel system, the hydraulic units and the respective system superstructures, a self-contained crew cell which is decoupled from the vehicle and has at least one roof exit and/or rear exit, as well as electrical, pneumatic and/or hydraulic interfaces in the interior and exterior areas of the chassis for the connection of the respective work equipment adapted on or in the chassis, and adapted on or in the chassis.

US 2007/0089925 Al describes a wheeled vehicle with a crane superstructure.

DE 10 2013 218 236 Al shows modular truss elements for trusses for lifting loads, wherein longitudinal and cross beam modules are provided, wherein the longitudinal beams and/or the cross beams can be extended at the ends — by telescopically arranged strokes and the free ends of the innermost strokes of the longitudinal beams can be detachably connected to cross beams or load-bearing elements and/or the free ends of the innermost strokes of the cross beams can be connected to load-bearing elements.

CN 203079587 U describes a modular crane superstructure.

DE 20 2004 004 805 U1 shows a mobile crane with a headlight and/or camera, whereby at least one headlight and/or at least one camera can be adjusted at one point on the mobile crane by means of an associated actuator.

Armored recovery vehicles, vehicles for recovering and Towing heavy equipment, are equipped with various devices such as winches, lifting devices and cranes, which can and may only pick up loads vertically. The use of a crane is subject to legal regulations, guidelines and standards. These also specify the use and intended use. Based on the interpretation of these specifications, such cranes may only lift loads vertically upwards.

Here, the invention sets itself the task of using a crane that is installed as a universal recovery crane on a tracked vehicle and can lift loads not only vertically. The relevant standards for cranes, lift operation and winches must be observed.

The task is solved by the features of claim 1. Advantageous embodiments are contained in the subclaims.

In accordance with the task, the invention is based on the idea of designing a crane in such a way that it can pick up and/or lift loads not only vertically but also in space. The crane is described as universal due to this versatile load pick-up. This "recovery extension arm", which can be used instead of a conventional crane system of a recovery tank or an excavator system of an arr mored engineer vehicle, is by the fact that the universal crane comprises or has at least two independent winch systems. Both winches can work independently of each other or together (in parallel). The two winch systems are used to lift and pull the load.

A crane head is equipped with at least one rotary cable guide head which, moving around its axis of rotation, allows the cable to be deployed in all directions. Preferably, the crane head is formed by at least two cable guide heads.

The ropes themselves are each attached to a cable winch and can therefore be wound or unwound on the cable winch. Each of the cable winches is provided with a drive for this purpose, which operates manually or by motor. A rotary lever can be provided for manual actuation and a motor, preferably a hydraulic or electric motor, for motorized movement.

Each cable is guided from the cable winch through the extension arm to the cable guide heads, at which the cables are guided out of the extension arm.

Preferably, the ends of the cables are provided with fastening means by means of which the loads to be picked up are attached to the respective cable.

This can be a mechanical fastener, but also a magnetizable one.

The crane used as a universal recovery crane consists of a slewing bracket and a crane extension arm (=extension arm). A sensor technology integrated in the crane comprises, among other things, at least one pressure transducer, at least one displacement transducer, at least one protractor and/or at least one load cell, etc. It is understood that combinations are possible. The integration or attachment of this sensor technology can be provided on the slewing Console and/or on (in) the extension arm of the crane. These sensors are used to monitor that the crane or the crane extension arm itself does not pick up excessive loads. The stability of the vehicle can also be measured and monitored. As a result of the measurements taking place in the background, the vehicle is prevented from tipping over. The measurements monitor the forces, and load torques applied and can be displayed, signaled and given as a warning to the crane operator. The position of the extension arm in relation to the vehicle chassis etc. can also be determined with the aid of the displacement transducer. This information can also be used as an aid working with the crane. However, this type of monitoring also allows the crane to work autonomously.

In a preferred embodiment, at least one spotlight and at least one camera are attached to the extension arm to facilitate working with the crane. The at least one Spotlight also makes it possible to work at night. The Spotlight and camera should be mounted in close proximity to each other. The extension arm is the preferred place of attachment. Since the extension arm can change its position or orientation, the at least one Spotlight and the at least one camera should also be able to change their orientation. This change should at least be made in relation to the extension arm when the Spotlight and camera are attached to the extension arm. The Spotlight and camera can be attached to the side or underneath the extension arm.

Furthermore, it is planned that special equipment can be carried in the extension arm. For military use, it should be possible to integrate Adaptive protection on the extension arm.

The swivel bracket consists of at least one swivel mechanism, at least one rotary union, at least one swivel bearing and at least one rocker cylinder. The swivel joint can be designed with hydraulic and/or electrical connections, and these can be designed as a quick disconnect device. This makes it possible to replace the crane. At the very least, however, these connections can be disconnected when not in use, which is particularly advantageous when driving — or transporting the vehicle.

Thanks to the special type of rope guide and its use, the universal crane created in this way can be used in a variety of ways. This rope guide in different directions enables complicated lifting and recovery operations. The load receptacles attached to the crane extension arm allow the rope to be attached there in order to use an additional rope pulley to double the force.

The doubling of force is caused by the fact that the vehicle according to the invention has a crane which can lift or carry loads in two lifting modes. For this purpose, the extension arm has at least two winches, which can wind and unwind at least two winch cables, at least two cable guide heads, through which the winch cables are guided out of the extension arm, and at least two lifting eyes. The lifting eyes are attached in the area of the end of the extension arm at which the cable guide heads are also arranged.

The first type of lift is the so-called single lift, in which the load is attached to the end of a winch cable. For this purpose, the end of the winch cable can be fitted with a fastener, such as a carabiner. In this type of lift, the load is lifted and/or lowered by the simple lifting movement of the winch cable. The winch cable is guided through the cable guide heads from the cable winch through the extension arm to the load.

The rotary movement of the cable winch is therefore carried out at the same speed as the lifting and/or lowering movement of the load. In this lifting mode, one load can be lifted per winch cable or a single load together with both winch cables. When lifting a single load, the lifting force can be doubled as the required lifting force is distributed over both winch cables.

The second type of lift is the so-called double lift, in which a redirection roller is first attached to the end of a winch cable. The redirection roller can be fitted with a fastener, such as a carabiner. The end of the winch cable is guided over the redirection roller and attached to a lifting eye. Here too, the end of the winch cable can be provided with a fastener. In this type of lift, the load is lifted and/or lowered by the double lifting movement of the winch cable, as the winch cable is guided over the redirection roller. The winch cable is guided here by the cable guide heads from the cable winch through the extension arm to the redirection roller and then to the lifting eye.

The rotary movement of the cable winch is therefore carried out at twice the speed of the lifting and/or lowering movement of the load. In this type of lift, one load per winch cable can also be lifted or a single load together with both winch cables. When lifting one load per winch cable, the lifting force is already doubled by the deflection compared to the single lift. When lifting a single load, the lifting force can therefore be doubled again compared to the single lift of a single load, as the required lifting force is also distributed over both winch cables.

At least one rope cleaning should be provided for cleaning the ropes.

The invention will be explained in more detail on the basis of an embodiment example with drawings. It shows:

Fig. 1 A crane according to the invention on a tracked vehicle,

Fig. 2 the structure of the crane from Fig. 1,

Fig. 3 Sketch of the double lift.

Fig. 1 shows a tracked vehicle 100 with a vehicle chassis 10 on which a crane 2 is mounted. This crane 2 can be attached to the vehicle chassis 10 but can also be replaced by another crane. A holder for an attachable cabin, not shown in detail, is marked 1. This can be used to operate the crane 2 as well as to supply the vehicle 100.

The crane 2 can be attached to the vehicle chassis 10 as a side or center arrangement.

Fig. 2 shows the structure of the crane 2 in more detail. The crane 2 as a universal recovery crane consists of a slewing bracket 2.1 and an extension arm 2.2. A sensor technology 2.3 is integrated at the rear part of the extension arm 2.2, here in the area of the slewing bracket 2.1. This sensor technology 2.3 comprises, among other things, at least one pressure sensor, at least one displacement sensor, at least one angle sensor and/or at least one load cell, etc.

In a preferred embodiment, at least one Spotlight 2.4 and one camera 2.5 are attached to the extension arm 2.2. This attachment can be at the side or from below on the extension arm 2.2.

Furthermore, it is intended that equipment 2.6 can be integrated on the crane 2. The extension arm 2.2 of crane 2 is particularly suitable here.

Furthermore, it is intended that the extension arm 2.2 can also be provided with Adaptive protection 2.7. This protection can be protection against dirt and environmental influences, etc., but also ballistic protection, e.g. against — bullets, etc.

The swivel bracket 2.1 comprises at least one swivel mechanism 2.1.1, at least one swivel bearing 2.1.3 and at least one rocker cylinder 2.1.4. The swivel bracket 2.1 is also provided with at least one rotary feed-through 2.1.2. This rotary union(s) can be designed with hydraulic and/or electrical connections, and these can be designed as a quick disconnect device.

The extension arm 2.2 has at least two winches 2.2.1. These winches 2.2.1 can be used independently of each other or in parallel operation.

Furthermore, the extension arm 2.2 comprises at least two winch ropes 2.2.2, at least two rope guide heads 2.2.3 and at least two lifting eyes 2.2.4. This quantity depends on the number of winches 2.2.1 used.

Preferably, at least one cable cleaning 2.2.5 is provided in the system.

The extension arm 2.2 can be designed as a rigid variant, as an articulated arm or telescopic arm extension arm.

It works as follows:

The crane 2 of the vehicle 100 has two different types of lifting, by means of — which different lifting forces are made possible for lifting a load. Firstly, the winches (2.2.1) are arranged in the extension arm (2.2), on which the winch ropes (2.2.2) can be wound and unwound. This can be done manually or by motor using a drive for each winch (2.2.1). — The winch cables (2.2.2) are guided through the extension arm (2.2) and emerge from the extension arm (2.2) at the cable guide heads (2.2.3). The rope guide heads (2.2.3) can guide the winch ropes (2.2.2) out of the extension arm (2.2) in all directions, as they are arranged rotationally on the extension arm (2.2).

The winch ropes (2.2.2) can each be attached to at least one load. When the winch ropes (2.2.2) are roped onto the winches (2.2.1), the loads are lifted.

The lifting speed corresponds to the single winch speed, which is why this type of lift is described as a single lift. Each winch rope (2.2.2) can lift the single maximum rope load, which can be determined by the rope thickness and the material of the winch rope (2.2.2).

It does not matter whether only one load per winch rope (2.2.2) is lifted or a combined load of several winch ropes (2.2.2) is lifted. The single maximum rope load is available for each winch rope (2.2.2).

In the so-called double lift, which is shown in Figure 3, at least one winch cable (2.2.2) is attached to one of the lifting eyes (2.2.4) and provided with a re-direction roller (2.2.6). This creates a double rope guide to the load (3), namely from the extension arm (2.2) via the redirection roller (2.2.6) to the lifting eye (2.2.4). The load (3) to be lifted is attached to the redirection roller so that twice the rope strength is now available for lifting the load (3). The lifting speed corresponds to half the winch speed. Each winch rope (2.2.2) can lift twice the maximum rope load.

Even in the double lift, it does not matter whether only one load (3) per — winch rope (2.2.2) is lifted or a joint load of several winch ropes (2.2.2) is lifted. Twice the maximum rope load is available per winch rope (2.2.2).

It should be noted that Figure 3 is only a sketch and does not claim to be exhaustive.

However, the essential features of the double lift of a vehicle with crane according to the invention are shown.
