TRACKED VEHICLE WITH UNIVERSAL CRANE

Description

[0001] The invention relates to a tracked vehicle equipped with a crane. The invention particularly relates to a military tracked vehicle, such as an armored recovery vehicle or armored engineer vehicle, which can be equipped with a crane as a recovery crane.

[0002] DE 10 2006 034 688 A1 discloses an armored support vehicle with the features of the preamble of claim 1. It is characterized by the fact that it can be upgraded or converted for various tasks as a recovery, bridge-laying, engineer, or mine-clearing vehicle. For this purpose, it has a common modular vehicle chassis. This vehicle chassis serves to accommodate the various implements required to perform the various tasks.

[0003] AT 004 275 U1 relates to a vehicle for firefighting and rescue operations. In an advantageous embodiment, a foldable searchlight is mounted on the roof of the vehicle, which can be moved through an angle of 340°.

[0004] DD 281 935 A3 deals with a base vehicle converted into an armored recovery vehicle. For this purpose, a support made of two welded tubes is movably mounted. A square section is welded to the upper end, to which a bracket for holding the water recovery rope and tensioning cables is attached. DE 20 2013 102 281 U1 discloses a winch with a monitoring device. This device is intended to prevent the traction device from being retracted too far, even if the traction device is not running vertically.

[0005] This prevents damage to the rope, hook or other attachment devices.

[0006] DE 812 980 U1 discloses a recovery vehicle with a main lifting device and a jib crane supported on the vehicle. A mechanical connection is provided between the main lifting device, designed as a main boom, and the crane boom. This mechanical connection connects the main lifting device to the crane boom for raising the main lifting device to the crane boom. This creates a recovery vehicle with jib crane lifting capabilities and the option of supported or suspended towing. However, only one or two hydraulic cylinders are required to raise the crane boom and the main boom.

[0007] DE 791 792 111 describes a mobile crane with a telescopic boom with hoist rope pivoted on a rotating superstructure.

[0008] DE 36 13 603 A1 discusses the creation of a multi-purpose recovery vehicle with a chassis mounted on wheels, a jib crane arranged on the chassis and a recovery device arranged at the rear end of the chassis.

[0009] DE 20 2009 005 446 111 proposes a mobile crane with a single-cab solution for ferry and crane operations. The driver's cab can be swiveled in the opposite direction to the boom head and, for road travel, can be detachably connected to a crane's undercarriage in a travel position with an opposite viewing angle to the boom head.

[0010] DE 10 2006 034 688 A1 shows a universal support vehicle for combinable tasks of a recovery, bridge-laying, engineer 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 crew cell which is decoupled from the vehicle and is self-contained 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 of the chassis for connecting the respective work tools and manual tools adapted on or in the chassis.

[0011] US 2007 / 0089925 A1 describes a wheeled vehicle with a crane body.

[0012] DE 10 2013 218 236 A1 shows modular truss elements for trusses for lifting loads, wherein longitudinal and cross member modules are provided, wherein the longitudinal and / or cross members are extendable by telescopically arranged hubs at the ends and the free ends of the innermost hubs of the longitudinal members are detachably connectable to cross members or load-bearing elements and / or the free ends of the innermost hubs of the cross members are connectable to load-bearing elements.

[0013] The CN 203079587 U describes a modular crane structure.

[0014] DE 20 2004 004 805 U1 shows a mobile crane with a spotlight and / or camera, wherein at least one spotlight and / or at least one camera can be adjusted at a location on the mobile crane by means of an associated actuator.

[0015] Armoured recovery vehicles, vehicles used to recover and tow heavy equipment, are equipped with various devices such as cable winches, lifting devices, and cranes, which can and may only lift loads vertically. The use of a crane is subject to legal regulations, guidelines, and standards. These also specify the use and intended use. Therefore, in interpreting these regulations, such cranes may only lift loads vertically.

[0016] The invention addresses the problem 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, hoisting equipment, and winches must be observed.

[0017] The problem is solved by the features of patent claim 1. Advantageous embodiments are contained in the subclaims.

[0018] According to the task, the invention is based on the idea of ​​designing a crane so that it can pick up and / or lift loads not only vertically but also spatially. This versatile load-carrying capability makes the crane universal. This "recovery boom," which can be used instead of a conventional crane system on an armored recovery vehicle or an excavator system on an armored engineer vehicle, is characterized by the fact that the universal crane comprises or has at least two independent winch systems. Both winches can operate independently of each other or together (in parallel). The two winch systems are used to lift and pull the load.

[0019] A crane head is equipped with at least one rotating rope guide head, which, moving around its axis of rotation, allows rope deployment in all directions. Preferably, the crane head is formed by at least two rope guide heads.

[0020] The ropes themselves are each attached to a cable winch and can thus be wound or unwound on the cable winch. Each of the cable winches is equipped with a drive, which operates manually or by a motor. A rotary lever can be provided for manual operation, and a motor, preferably a hydraulic or electric motor, can be provided for motorized movement.

[0021] Each rope is guided from the cable winch through the boom to the rope guide heads, where the ropes exit the boom. The ends of the ropes are preferably equipped with fasteners by means of which the loads to be carried are attached to the respective rope. This can be a mechanical fastener or a magnetizable one.

[0022] The crane used as a universal recovery crane consists of a slewing bracket and a crane boom (=jib). Sensors integrated into the crane include, among other things, at least one pressure sensor, at least one displacement sensor, at least one angle gauge, and / or at least one load cell, etc. Combinations are possible. These sensors can be integrated or mounted on the slewing bracket and / or on (in) the boom of the crane. These sensors monitor that the crane or the crane boom itself does not bear excessive loads. The stability of the vehicle can also be measured and monitored. The result of the measurements taking place in the background is to prevent the vehicle from tipping over. The measurements monitor the applied forces and load moments and can be displayed, signaled, or issued as a warning to a crane operator.The position sensor can also be used to determine the position of the boom relative to the vehicle chassis, etc. This information can also be used as an aid when operating the crane. Such monitoring also allows the crane to operate independently.

[0023] In a preferred embodiment, at least one spotlight and at least one camera are attached to the boom to make working with the crane easier. The at least one spotlight makes working at night possible. The spotlight and camera should be attached in close proximity to one another. The boom is considered the preferred location for attachment. Since the boom 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 occur at least relative to the boom if the spotlight and camera are attached to the boom. The spotlight and camera can be attached to the side or underneath the boom.

[0024] Furthermore, it is planned to allow for the carrying of special equipment in the boom. For military use, adaptive protection should be integrated into the boom.

[0025] The slewing bracket consists of at least one slewing mechanism, at least one rotary union, at least one slewing bearing, and at least one luffing cylinder. The rotary union can be designed with hydraulic and / or electrical connections, and these can be configured as quick-disconnect devices. This allows for the crane to be interchangeable. At the very least, these connections can be disconnected when not in use, which is particularly advantageous when driving or transporting the vehicle.

[0026] Thanks to the special type of rope guidance and its use, the resulting universal crane can be used in a variety of ways. This rope guidance in different directions enables complex lifting and recovery operations. The load attachments attached to the crane boom allow the rope to be attached there, allowing an additional rope block to be used to double the force.

[0027] The doubling of force is achieved by the fact that the vehicle according to the invention has a crane that can lift or carry loads in two lifting modes. The boom has at least two winches that 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 boom, and at least two attachment eyes. The attachment eyes are mounted near the end of the boom, where the cable guide heads are also located.

[0028] The first lifting type 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 equipped with a fastening device, such as a carabiner. In this lifting type, the load is raised and / or lowered by the simple lifting movement of the winch cable. The winch cable is guided by the cable guide heads from the cable winch through the boom to the load.

[0029] The rotational movement of the cable winch is thus carried out at the same speed as the lifting and / or lowering movement of the load. With this lifting method, one load can be lifted per winch cable, or a single load can be lifted together using both winch cables. When lifting a single load, the lifting force can be doubled because the required lifting force is distributed across both winch cables.

[0030] The second lifting type is the so-called double lift, in which a pulley is first attached to the end of a winch rope. The pulley can be equipped with a fastening device, such as a carabiner. The end of the winch rope is guided over the pulley and attached to an attachment eye. In this case, too, the end of the winch rope can be provided with a fastening device. In this type of lifting, the load is raised and / or lowered by the double lifting movement of the winch rope, as the winch rope is guided over the pulley. The winch rope is guided by the rope guide heads from the cable winch through the boom to the pulley and then to the attachment eye.

[0031] The rotational movement of the cable winch is thus carried out at twice the speed of the lifting and / or lowering movement of the load. With this type of lifting, one load can be lifted per winch cable, or a single load can be lifted together using both winch cables. When lifting one load per cable winch, the lifting force is doubled compared to a single lift due to the deflection. When lifting a single load, the lifting force can therefore be doubled again compared to a single lift of a single load, since the required lifting force is also distributed across both winch cables.

[0032] At least one rope cleaning system should be provided to clean the ropes.

[0033] The invention will be explained in more detail using an exemplary embodiment 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. 3Sketch representation of the double stroke.

[0034] The Fig. 1 shows a tracked vehicle 100 with a vehicle chassis 10, onto which a crane 2 is mounted. This crane 2 can be attached to the vehicle chassis 10, but can also be exchanged for another crane. 1 denotes a mount for a mountable cabin (not shown in detail). This can be used to operate the crane 2 as well as to drive the vehicle 100.

[0035] The crane 2 can be mounted on the vehicle chassis 10 as a side or center arrangement.

[0036] In Fig. 2The structure of crane 2 is shown in more detail. Crane 2, as a universal recovery crane, consists of a swivel bracket 2.1 and a boom 2.2. A sensor system 2.3 is integrated into the rear part of the boom, here in the area of ​​the swivel bracket 2.1. This sensor system 2.3 includes, among other things, at least one pressure sensor, at least one displacement sensor, at least one angle gauge, and / or at least one load cell, etc.

[0037] In a preferred embodiment, at least one spotlight 2.4 and one camera 2.5 are attached to the boom 2.2. This attachment can be made from the side or from below on the boom 2.2.

[0038] Furthermore, it is intended that equipment 2.6 can be integrated into crane 2. The boom 2.2 of crane 2 is particularly suitable for this purpose.

[0039] Furthermore, it is planned that the boom 2.2 can also be equipped with adaptive protection 2.7. This protection can be against dirt and environmental influences, etc., but also of a ballistic nature, e.g., against bullets, etc.

[0040] 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 luffing cylinder 2.1.4. The swivel bracket 2.1 is also equipped with at least one rotary union 2.1.2. This rotary union(s) can be equipped with hydraulic and / or electrical connections, and these can be designed as quick-disconnect devices.

[0041] The boom 2.2 has at least two winches 2.2.1. These winches 2.2.1 can be used independently or in parallel.

[0042] The boom 2.2 further comprises at least two winch cables 2.2.2, at least two cable guide heads 2.2.3, and at least two anchor eyes 2.2.4. This quantity depends on the number of winches 2.2.1 used.

[0043] Preferably, at least one rope cleaning 2.2.5 is provided in the system.

[0044] The boom 2.2 can be designed as a rigid version, as an articulated boom or as a telescopic boom. It works as follows:

[0045] Crane 2 of vehicle 100 has two different lifting modes, enabling different lifting forces for lifting a load. First, the winches (2.2.1) are arranged in the boom (2.2), on which the winch cables (2.2.2) can be wound and unwound. This can be done manually or motor-driven using a drive for each winch (2.2.1).

[0046] The winch ropes (2.2.2) are guided through the boom (2.2) and exit the boom (2.2) at the rope guide heads (2.2.3). The rope guide heads (2.2.3) can guide the winch ropes (2.2.2) out of the boom (2.2) in all directions, as they are arranged in a rotational manner on the boom (2.2).

[0047] The winch ropes (2.2.2) can each be attached to at least one load. When the winch ropes (2.2.2) are attached to the winches (2.2.1), the loads are then lifted. The lifting speed corresponds to the winch speed, which is why this type of lifting is described as a single lift. Each winch rope (2.2.2) can lift the maximum rope load, which can be determined by the rope thickness and material of the winch rope (2.2.2).

[0048] It doesn't matter whether only one load is lifted per winch rope (2.2.2) or a combined load is lifted by several winch ropes (2.2.2). The single maximum rope load is available for each winch rope (2.2.2).

[0049] In the so-called double stroke, which Figure 3 As shown, at least one winch rope (2.2.2) is attached to one of the attachment eyes (2.2.4) and fitted with a deflection pulley (2.2.6). This creates a double rope guide to the load (3), namely from the boom (2.2) via the deflection pulley (2.2.6) to the attachment eye (2.2.4). The load to be lifted (3) is attached to the deflection pulley, so that twice the rope strength is now available for lifting the load (3). The lifting speed here corresponds to half the winch speed. Each winch rope (2.2.2) can lift twice the maximum rope load.

[0050] Even in a double lift, it doesn't matter whether only one load (3) is lifted per winch rope (2.2.2) or a combined load is lifted by several winch ropes (2.2.2). Double the maximum rope load is available per winch rope (2.2.2).

[0051] It is pointed out that Figure 3 is only sketched and does not claim to be complete. However, the essential features of the double lift of a vehicle with a crane according to the invention are shown.
