[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Combined with reference Figure 1-Figure 4 The utility model provides a motor vehicle coupling cover disassembly device, comprising a tool plug rod 1 for inserting into the center hole of the coupling cover plate. In the present application, the size of the tool plug rod 1 should be smaller than the size of the center hole of the cover plate. A pair of handles 11 are fixedly connected to the top of the outer surface of the tool plug rod 1. A pair of cylindrical gears 2 are rotatably connected to the inner side of the tool plug rod 1. Both ends of the cylindrical gear 2 are fixedly connected with a push rod 3. The width of the pair of push rods 3 and the tool plug rod 1 should be smaller than the size of the center hole of the cover plate, so that it can be conveniently inserted into the coupling. By unfolding the push rod 3, the lower surface of the cover plate is acted on. The vertical arrangement of the push rod 3 and the tool plug rod 1 can increase the force-bearing surface of the cover plate traction, and the force is more uniform. In this way, the cover plate can be removed by pulling the tool plug rod 1 upward. The push rod 3 is arranged on the outer side of the tool plug rod 1. The push rod 3 is used to abut against the lower surface of the coupling cover plate. A rotating transmission member 4 for transmitting the cylindrical gear 2 is arranged on the inner side of the tool plug rod 1, and a pressing member 5 connected to the rotating transmission member 4 is arranged on the top of the tool plug rod 1.
[0022] The rotating transmission member 4 includes a slide plate 41 and a tooth block group 42 fixedly connected to the side of the slide plate 41. The tooth block group 42 is meshed with the cylindrical gear 2. In the present application, the tooth block group 42 is arranged in sequence by a plurality of tooth blocks. By controlling the vertical descent of the slide plate 41, the tooth block group 42 is driven to mesh with the cylindrical gear 2. By driving the cylindrical gear 2 to rotate, the push rod 3 on the tool rod 1 can be rotated and spread out vertically with the tool rod 1. The push rod 3 is vertically distributed with the tool rod 1 on the cover plate of the coupling. By providing an upward pulling force, a balanced pulling force can be provided to the cover plate of the coupling for removal.
[0023] A slide rail 7 is fixedly connected to the inner wall of the tool insertion rod 1, and the slide plate 41 is slidably connected to the slide rail 7. The slide rail 7 can be used to guide the slide plate 41 to ensure that the slide plate 41 is always in a vertical sliding state.
[0024] The pressing member 5 includes a T-shaped traction rod 51 that movably passes through the top of the tool insertion rod 1, a fixed block 52 that is fixedly connected to the bottom end of the T-shaped traction rod 51, and a return spring 53 that is sleeved on the outer surface of the vertical section of the T-shaped traction rod 51. The fixed block 52 is fixedly connected to the side of the slide plate 41, and the return spring 53 arranged on the T-shaped traction rod 51 is set at the top position of the tool insertion rod 1. In this application, the T-shaped traction rod 51 can be set on the tool insertion rod 1 through a linear bearing, and the linear bearing can be embedded in the top of the tool insertion rod 1.
[0025] Specifically, by pressing the T-shaped traction rod 51, the return spring 53 can be compressed, so that the slide plate 41 can drive the tooth block group 42 to move downward and mesh with the cylindrical gear 2 until the return spring 53 is at the maximum compression amount. At this time, the push rod 3 can be rotated to a state perpendicular to the tool insertion rod 1. At this time, the lateral section of the T-shaped traction rod 51 after being pressed down is close to the position of the handle 11. A person can hold the T-shaped traction rod 51 and the handle 11 at the same time, and apply an upward pulling force, so that the cover plate on the coupling can be removed. Therefore, in this application, the tool insertion is adopted. The rod 1 and the push rod 3 which can be adjusted in the horizontal and vertical directions are matched on the cover plate of the coupling. The force position can be balanced by expanding the force-bearing surface to remove the cover plate. This can avoid the use of a tilting tool to remove the coupling cover plate by tilting. The tilting method causes uneven force on the cover plate, and the tilting process is likely to cause technical problems such as structural deformation of the cover plate. In addition, when the pressure on the T-shaped traction rod 51 is released, the return spring 53 can reset the slide plate 41 and allow the push rod 3 to rotate back to a state parallel to the tool insertion rod 1, which can reduce the operation volume.
[0026] The outer surface of the vertical section of the T-shaped traction rod 51 is fixedly connected to a limit ring 8 , which is arranged at the inner top position of the tool insertion rod 1 . The limit ring 8 can limit the moving path of the T-shaped traction rod 51 .
[0027] A rubber plate 9 is provided on one side of the push rod 3 , and a positioning column 10 is integrally connected to the rubber plate 9 . The positioning column 10 is elastically plugged into the push rod 3 .
[0028] By arranging a rubber plate 9 on the side of the top rod 3, when the top rod is laterally arranged and parallel to the coupling cover plate, the rubber plate 9 can be easily fitted on the lower surface of the cover plate, so that when the top rod 3 is pulled upward, the rubber plate 9 can reduce the hardness of the contact position between the top rod 3 and the cover plate to avoid damage caused by disassembly of the cover plate; in addition, because the positioning column 10 is integrally arranged on the rubber plate 9, the positioning column 10 adopts the same rubber material as the rubber plate 9, and utilizes the setting of the rubber elastic material, so that it can be easily disassembled on the top plate 3, which satisfies the convenience of disassembly and assembly.
[0029] A handle 6 is fixedly connected to the tool rod 1, and the handle 6 is arranged on one side of the middle of the tool rod 1, so that the entire EMU coupling cover plate removal device can be easily lifted and moved, which meets the convenience of carrying.
