Description

Technical Field

[0001] The utility model relates to the technical field of fast spring clip assembly and disassembly, in particular to a device for assembling and disassembling a fast spring clip. Background Art

[0002] In the fast spring clip fasteners in the field of rail transit, the fast spring clip needs to be moved forward and backward in the spring clip seat of the iron pad for installation and removal, and the fast spring clip needs to be operated with tools when moving forward and backward. Due to the structural characteristics of the fast spring clip, its buckling pressure will change during the movement. The buckling pressure of the fast spring clip in the working position can reach up to 9kN. The friction between the fast spring clip and the spring clip seat at several main contact points is relatively large. Therefore, the fast spring clip requires a large propulsion force during the movement. However, manual tools are mostly used in the prior art, and most of the manual tools use the lever principle to amplify the power provided by the operator. The larger lever amplification ratio results in a larger necessary working range for its work. For example, the patent document CN213447897U in the prior art discloses a spring clip fastener disassembly and assembly device. The device comprises: a frame, which is slidably arranged on a track; a mounting frame, which is arranged on the frame; and a disassembly and assembly mechanism, which comprises: two groups of disassembly and assembly units, each group of disassembly and assembly units comprises a main arm and a working claw arranged at the lower end thereof, the middle parts of the two main arms are rotatably arranged on both sides of the mounting frame, and the working claws are staggered in the length direction of the frame; and a driving cylinder is also included, which is connected to the upper ends of the two main arms and is used to drive the two groups of main arms to drive the working claws to grab and disassemble the spring strips. It is difficult to use in some places with a narrow working range; at the same time, since the power source is the operator himself, the work intensity of the staff is relatively large.
