[0013] ​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0014] Embodiment one Please refer to Figures 1-7 The embodiment of the present application provides a structure for reducing the moving resistance of a wrecker, comprising a bottom plate 1, two C-shaped slides 4, two slide rails 5 and rollers 6.

[0015] The bottom of the bottom plate 1 is fixedly connected with two longitudinal beams 3, and the two C-shaped slides 4 are fixedly connected to the bottom of the two longitudinal beams 3. The inner side wall of the C-shaped slide 4 is fixedly connected with a plurality of moving auxiliary mechanisms. The two slide rails 5 are arranged in the interior of the C-shaped slide 4, and the two ends of the interior of the slide rail 5 are fixedly connected with two mounting rods 10. The rollers 6 are fixedly connected to the exterior of the mounting rod 10, and the rollers 6 are rollingly connected to the interior of the C-shaped slide 4.

[0016] Among them, the bottom of the bottom plate 1 is also fixedly connected with a plurality of cross beams 2 at equal intervals, and the longitudinal beam 3 is fixedly connected to the bottom of the cross beam 2 by welding.

[0017] The bottom plate 1 is the core bearing surface of the flat plate of the wrecker, and a plurality of cross beams 2 are fixedly arranged at equal intervals at the bottom of the bottom plate 1. The cross beams 2 are distributed transversely to disperse the pressure borne by the bottom plate 1. The two longitudinal beams 3 are fixedly arranged at the bottom of the cross beam 2 by welding, and the longitudinal beam 3 and the cross beam 2 form a support frame intersecting longitudinally and transversely. The support frame has a high welding density, so that the bottom plate 1, the cross beam 2 and the longitudinal beam 3 are integrated. The C-shaped slide 4 is further fixedly arranged at the bottom of the longitudinal beam 3, and the two C-shaped slides 4 are oppositely arranged with openings. This not only ensures the firm connection of the C-shaped slide 4 and the support frame, but also provides a stable track cavity for the embedding and moving of the subsequent slide rail 5. Through the structure, the bearing capacity and structural strength of the whole flat plate are significantly improved, so that the collapse and deformation of the bottom plate 1 when the wrecker bears the accident vehicle can be avoided, and the stable operation of the flat plate is ensured.

[0018] Among them, the moving auxiliary mechanism comprises two fixed pieces 7, the two fixed pieces 7 are fixedly connected with a fixed rod 8, and the exterior of the fixed rod 8 is fixedly connected with a bearing 9.

[0019] Among them, two through grooves 11 are further arranged on the slide rail 5, and the two rollers 6 respectively penetrate through the two through grooves 11.

[0020] In addition, each set of mobile auxiliary mechanism is composed of two fixed pieces 7, a fixed rod 8 and a bearing 9. The fixed pieces 7 are directly welded on the inner side wall of the C-shaped slide 4, the fixed rod 8 is transversely connected to the two fixed pieces 7, and the bearing 9 is rotatably sleeved on the outside of the fixed rod 8. When the C-shaped slide 4 moves forward and backward along the slide rail 5, the bearing 9 forms rolling contact with the side wall of the slide rail 5. Compared with traditional sliding contact, the rolling friction can greatly reduce the longitudinal moving resistance between the C-shaped slide 4 and the slide rail 5. At the same time, the lateral limiting effect of the bearing 9 on the slide rail 5 can reduce the lateral deviation of the C-shaped slide 4 during movement, and has the positioning and guiding effect. This process not only reduces the friction loss, but also reduces the bearing force of the hydraulic system driving the flat plate to move, so that the flat plate moves more stably and reduces the jamming during movement.

[0021] Embodiment two Please refer to Figures 2-5 Two mounting rods 10 are fixed at both ends inside the slide rail 5, and the rollers 6 are rotatably sleeved on the outside of the mounting rods 10. At the same time, two through grooves 11 are formed on the slide rail 5, and the rollers 6 respectively penetrate the through grooves 11, so that the outer side of the rollers 6 can be embedded in the inner cavity of the C-shaped slide 4 to form a nested structure. Whether the wrecker is in an empty load or a load working condition, when the flat plate needs to move, the C-shaped slide 4 will move in the rolling direction of the rollers 6, and the rolling friction of the rollers 6 replaces the direct sliding friction between the C-shaped slide 4 and the slide rail 5, so as to minimize the moving resistance. This design not only reduces the wear of mechanical parts, but also reduces the load on the hydraulic system, thereby indirectly prolonging the service life of the hydraulic pump, the hydraulic cylinder and other hydraulic components.

[0022] The openings of the two C-shaped slides 4 are oppositely arranged.

[0023] According to the above technical scheme, the working steps of the present scheme are summarized and combed: the bottom plate 1 is the core bearing surface of the flat plate of the wrecker, a plurality of cross beams 2 are fixed at the bottom at equal intervals, the cross beams 2 are distributed transversely to disperse the pressure borne by the bottom plate 1; two longitudinal beams 3 are fixed at the bottom of the cross beams 2 by welding, and the longitudinal beams 3 and the cross beams 2 form a support frame intersecting longitudinally and transversely. The support frame has high welding density, so that the bottom plate 1, the cross beams 2 and the longitudinal beams 3 are integrated. The C-shaped slide 4 is further fixed at the bottom of the longitudinal beam 3, and the openings of the two C-shaped slides 4 are oppositely arranged, which not only ensures the firm connection of the C-shaped slide 4 and the support frame, but also provides a stable track cavity for the embedding and movement of the subsequent slide rail 5. Through the structure, the bearing capacity and structural strength of the whole flat plate are significantly improved, which can avoid the collapse and deformation of the bottom plate 1 of the wrecker when carrying the accident vehicle, and ensure the smooth operation of the flat plate. In addition, each group of moving auxiliary mechanism is composed of two fixed pieces 7, a fixed rod 8 and a bearing 9. Among them, the fixed piece 7 is directly welded on the inner side wall of the C-shaped slide 4, the fixed rod 8 is transversely connected with the two fixed pieces 7, and the bearing 9 is rotatably sleeved on the outside of the fixed rod 8. When the C-shaped slide 4 moves forward and backward along the slide rail 5, the bearing 9 will form rolling contact with the side wall of the slide rail 5. Compared with the traditional sliding contact, the rolling friction can greatly reduce the longitudinal moving resistance between the C-shaped slide 4 and the slide rail 5. The two mounting rods 10 are fixed at the both ends inside the slide rail 5, and the roller 6 is rotatably sleeved on the outside of the mounting rod 10; at the same time, two through slots 11 are formed on the slide rail 5, and the roller 6 penetrates through the through slots 11 respectively, so that the outer side of the roller 6 can be embedded in the inner cavity of the C-shaped slide 4 to form a nested structure. Whether the wrecker is in an empty load or a load working condition, when the flat plate needs to move, the C-shaped slide 4 will move in the rolling direction of the roller 6, and the rolling friction of the roller 6 replaces the direct sliding friction between the C-shaped slide 4 and the slide rail 5, so as to minimize the moving resistance.

[0024] The parts not involved in the present application are the same as or can be realized by the prior art. Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made therein without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
