Technical Field
[0001] The present application relates to the technical field of road tow trucks, and in particular to a detachable tail-tow structure for road tow trucks. Background Art
[0002] A road tow truck, also known as a tow truck, road rescue truck, or towing truck, has multiple functions such as lifting, pulling, and lifting and traction. Tow trucks are mainly used for road breakdown vehicles, urban illegal vehicles, and emergency rescue.
[0003] During the rescue process, new energy vehicles are prone to spontaneous combustion due to defects in battery technology, and are difficult to extinguish. If spontaneous combustion occurs on a tow truck and is not handled properly, it is very likely to cause the entire tow truck to be scrapped. In the existing technology, general staff will hang the new energy vehicle that has collided on the tail trailer for rescue, so as to keep it away from the main part of the tow truck, but it cannot completely prevent the accident of igniting the tow truck.
[0004] Therefore, it is urgent to develop a tail-tow structure that can unload the tail-tow in an emergency. Utility Model Content
[0005] The purpose of the present application is to provide a detachable tail-tow structure for a road tow truck to solve the problems raised in the above-mentioned background technology.
[0006] To achieve the above purpose, the present application provides a detachable tail-tow structure for a road tow truck adopting the following technical solution:
[0007] A detachable tail-tow structure for a road tow truck comprises a towing rod and a suspension frame, wherein the suspension frame is rotatably connected to the towing rod, the towing rod comprises an outer rod and an inner rod, the inner rod is movably arranged in the outer rod, a locking block is integrally formed on the surface of the inner rod, and the locking block can abut against the end wall of the outer rod;
[0008] The outer rod is provided with a locking member, which includes a hydraulic cylinder, a driving member and a locking rod. The driving member includes a looper movably mounted on the surface of the outer rod, and locking extrusion blocks are evenly fixed around one end of the looper close to the inner rod, and a force-unloading extrusion block is fixed at the other end of the looper corresponding to the position of the locking extrusion block. One end of the hydraulic cylinder is fixed to the outer rod, and the other end of the hydraulic cylinder is fixed to the looper for driving the looper to move. The number of the locking rods is consistent with the locking extrusion blocks. The middle part of the locking rod is hinged to the outer rod, and the end of the locking rod close to the locking block has an inwardly folded buckle edge. An opening and closing block is fixed to the other end of the locking rod, and the contact surfaces between the opening and closing block and the locking extrusion block are both slope surfaces, and the contact surfaces between the opening and closing block and the force-unloading extrusion block are also slope surfaces.
[0009] Preferably, the ratio of the length of the inner rod extending into the outer rod to the length of the outer rod is 1:3.
[0010] By adopting the above technical solution, the ratio setting can not only ensure that the inner rod has sufficient supporting force, but also ensure that the inner rod can slide out of the outer rod flexibly.
[0011] The bottom edge of the opening and closing block on one side close to the force unloading extrusion block is provided with a chamfer, and the surface of the loop is a smooth surface.
[0012] Preferably, a rubber pad is bonded and fixed to a surface of one side of the locking block close to the outer rod.
[0013] By adopting the above technical solution, on the one hand, the rubber pad can fill the gap between the outer rod and the locking block to ensure the locking effect, and on the other hand, the generation of noise can be reduced.
[0014] Preferably, in order to avoid accidental collision damage to the hydraulic cylinder during installation with a tow truck, a stop block is fixed to the side of the outer rod surface away from the inner rod, and the stop block is arranged next to the hydraulic cylinder.
[0015] Preferably, a chain is detachably connected between the outer rod and the inner rod.
[0016] By adopting the above technical solution, during normal use, the chain can play a dual protection role. Generally, when towing a new energy vehicle or the staff believes that the vehicle is prone to spontaneous combustion, the chain will be removed (or temporarily removed) to achieve the self-unloading function through the hydraulic cylinder.
[0017] In summary, the present application includes at least one of the following beneficial technical effects: the detachable tail-tow structure for the road tow truck is achieved by configuring the towing rod to be a detachable outer rod and an inner rod, and the outer rod and the inner rod are connected by a lock. In the event of an emergency, the inner rod and the suspension frame can be quickly thrown away as a whole, thereby preventing the spontaneously combusting vehicle from affecting the tow truck.

DETAILED DESCRIPTION
[0022] The following is combined with Figure 1-3 This application is described in further detail.
[0023] The present application embodiment discloses a detachable tail-tow structure for a road tow truck, referring to Figure 1-3 , including a traction rod 1 and a suspension frame 2, the suspension frame 2 is rotatably connected to the traction rod 1, the traction rod 1 is connected to the supporting arm at the rear of the tow truck, the traction rod 1 includes an outer rod 11 and an inner rod 12, the inner rod 12 is matched and movably arranged in the outer rod 11, and a locking block 121 is integrally formed on the surface of the inner rod 12, the locking block 121 can abut against the end wall of the outer rod 11, and a rubber pad is glued and fixed on the surface of the locking block 121 on one side close to the outer rod 11;
[0024] The outer rod 11 is provided with a lock, which includes a hydraulic cylinder 3, a driving member 4 and a locking rod 5. The driving member 4 includes a loop 41 movably sleeved on the surface of the outer rod 11. The loop 41 is evenly fixed with locking extrusion blocks 411 around one end close to the inner rod 12, and a force unloading extrusion block 412 is fixed at the other end of the loop 41 corresponding to the position of the locking extrusion block 411. One end of the hydraulic cylinder 3 is fixed on the outer rod 11, and the other end of the hydraulic cylinder 3 is fixed on the loop 41, which is used to drive the loop 41 to move. The number of locking rods 5 is the same as that of the outer rod 11. The locking extrusion block 411 is consistent with the locking extrusion block 411, the middle part of the locking rod 5 is hinged on the outer rod 11, and the end of the locking rod 5 close to the locking block 121 has an inwardly folded buckle edge 51, and the other end of the locking rod 5 is fixed with an opening and closing block 52. The contact surfaces between the opening and closing block 52 and the locking extrusion block 411 are both sloped surfaces, and the contact surfaces between the opening and closing block 52 and the unloading extrusion block 412 are also sloped surfaces. The bottom edge of the opening and closing block 52 close to the unloading extrusion block 412 is chamfered, and the surface of the slip ring 41 is smooth.
[0025] Reference Figure 3 The ratio of the length of the inner rod 12 extending into the outer rod 11 to the length of the outer rod 11 is 1:3. This ratio setting can not only ensure that the inner rod 12 has sufficient supporting force, but also ensure that the inner rod 12 can slide out of the outer rod 11 flexibly.
[0026] Reference Figure 1 In order to avoid accidental collision damage to the hydraulic cylinder 3 during the installation process with the tow truck, a stop block 6 is fixed on the side of the outer rod 11 away from the inner rod 12, and the stop block 6 is arranged next to the hydraulic cylinder 3.
[0027] In addition, a chain (not shown in the figure) is detachably connected between the outer rod 11 and the inner rod 12. During normal use, the chain can play a double protection role. Generally, when towing a new energy vehicle or the staff believes that the vehicle is prone to spontaneous combustion, the chain is removed (or temporarily removed) to achieve the self-unloading function through the hydraulic cylinder 3.
[0028] The implementation principle of a detachable tail-tow structure for a road tow truck in the embodiment of the present application is as follows:
[0029] When an emergency occurs, the staff only needs to drive the hydraulic cylinder 3 to extend, and the hydraulic cylinder 3 pushes the loop 41 to move toward the side of the inner rod 12. During this process, the locking squeeze block 411 gradually moves away from the closing block 52, and the unloading squeeze block 412 gradually presses on the opening and closing block 52. When the locking squeeze block 411 is completely away from the closing block 52, the unloading squeeze block 412 presses on the opening and closing block 52, so that the locking rod 5 can be tilted up, and the buckle edge 51 at the end of the locking rod 5 is separated from the locking block 121. After that, the tow truck only needs to move forward, which can prevent the spontaneous combustion vehicle from affecting the tow truck.
[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, principle and application direction of the present application should be included in the protection scope of the present application.
