Description

Technical Field

[0001] This utility model relates to the field of turnout switching machine technology, specifically a quick disassembly and assembly structure for turnout switching machine contact group. Background Technology

[0002] A switch is a switching device for railway turnouts. It is used to switch turnouts, lock turnouts, and indicate the position of the turnout switch rail. When a train switches from one track to another or wants to enter a maintenance yard or factory, there must be a special arrangement on the track to guide the wheel flanges smoothly into the designated track. This arrangement is called a turnout.

[0003] The patent CN222663448U discloses a contact group for a switch machine. This patent discloses a technical solution for stable support, which solves the problem that in the existing electric switch machine traction turnout conversion project, the contact piece itself relies on its elasticity to ensure reliable contact between the contact piece and the moving contact ring. After a certain period of use, the elasticity of the contact piece decreases, which will frequently cause poor contact, resulting in problems such as loose connection or open circuit.

[0004] When in use, the device uses a spring to press the contact plate against the surface of the moving contact post, which makes the connection between the contact plate and the moving contact post more reliable. However, the contact seat is mostly fixed to the base with multiple bolts, which is inconvenient for workers to disassemble and assemble the contact seat, reducing the effectiveness of use. Therefore, a quick disassembly and assembly structure for the turnout switch machine contact group is proposed to solve the above problems. Utility Model Content
