[0004] To achieve the above purpose, the utility model realizes the following technical scheme: including mechanism frame, the both sides of mechanism frame are equipped with corresponding circular through hole, the circular through hole is inserted with bearing, the bearing is installed with first connecting rod, a pair of stopper is installed on first connecting rod, and rope clamp is installed on first connecting rod and between a pair of stopper, and rope groove is formed in mechanism frame.
[0005] Preferably, the lower wall of the mechanism frame is provided with a clamping plate, and a rail clamping pin is installed on the clamping plate.
[0006] Preferably, a rocker is installed on the first connecting rod.
[0007] The utility model provides a device for dismantling rail passenger car brake shoes. It has the following advantages: simple structure, no deformation of the tool under stress, time and labor saving. BRIEF DESCRIPTION OF DRAWINGS
[0008] Fig. 1 The device for dismantling rail passenger car brake shoes is shown in the structure diagram.
[0009] Fig. 2 The rope clamp of the device for dismantling rail passenger car brake shoes is shown in the front view.
[0010] In the figure: 1 - mechanism frame; 2 - bearing; 3 - first connecting rod; 4 - stopper; 5 - rope clamp; 6 - rope groove; 7 - clamping plate; 8 - rocker; 9 - rail clamping pin. DETAILED DESCRIPTION
[0011] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0012] Please refer to Figs. 1-2 The present application provides a technical solution: a device for disassembling a brake shoe of a rail passenger car, comprising a mechanism frame 1, the mechanism frame 1 is provided with a circular through hole corresponding in position on both sides, a bearing 2 is inserted in the circular through hole, a first connecting rod 3 is installed between the bearings 2, a pair of stops 4 is installed on the first connecting rod 3, a rope clamp 5 is installed on the first connecting rod 3 and between the pair of stops 4, and a rope groove 6 is formed on the mechanism frame 1.
[0013] As a preferred technical solution, further, a clamping plate 7 is arranged on the lower wall of the mechanism frame 1, and a clamping rail pin 9 is installed on the clamping plate 7.
[0014] As a preferred technical solution, further, a rocker 8 is installed on the first connecting rod 3.
[0015] It should be noted that: first, place the tool on the surface of the rail, and then smoothly clamp the clamping plate 7 into the rail, and then use the clamping rail pin 9 to fix the tool on the rail, then fix one end of the steel wire rope on the mounting pin of the brake shoe device, and fix the other end of the steel wire rope on the rope clamp 5 through the rope groove 6, then rotate the rocker 8 clockwise, and then the mounting pin of the brake shoe device falls off, and then the brake shoe is removed.
[0016] It should be noted that, in this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, including the statement "including a...... limited element" does not exclude the existence of additional identical elements in the process, method, article, or apparatus that includes the limited element.
[0017] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
