Chassis vehicle

Abstract

The invention relates to a chassis vehicle. The chassis vehicle comprises a cross beam, a frame, a screw rod, an interlocking mechanism, a test position auxiliary switch and a working position auxiliary switch. The interlocking mechanism comprises a lock plate, a reset torsional spring and two groups of interlocking assemblies. The two groups of interlocking assemblies are arranged between the lock plate and the test position auxiliary switch and between the lock plate and the working position auxiliary switch. Each interlocking assembly comprises a sliding block, a pulling plate and a top plate. A first support rod and a second support rod are arranged on one side of the pull plate, and the first supporting rod abuts against the top plate. An interlocking sheet is arranged on the lock plate. The second supporting rod acts along with the pulling plate and can shift the interlocking sheet, locking or unlocking of the locking plate and the screw rod can be achieved, crank arms are connected between the sliding block of each interlocking assembly and the test position auxiliary switch and between the sliding block of each interlocking assembly and the working position auxiliary switchrespectively, the crank arms act along with the sliding blocks, and connection or disconnection of the test position auxiliary switch and the working position auxiliary switch can be achieved. The chassis vehicle is stable and reliable in performance, high in safety coefficient, small in operation force and sensitive in locking bounce.

Description

technical field [0001] The invention specifically relates to a chassis vehicle. Background technique [0002] With the advancement of power equipment manufacturing technology, the power supply quality of power equipment is becoming more and more stable. In order to further improve the automation level of the power system, various units in the power supply industry have fully launched the intelligent upgrading and transformation of substations. In order to enable the center-mounted vacuum circuit breaker to conveniently realize the functions of pushing in (pushing from the test position into the working position and locking) and withdrawing (exiting from the working position to the test position and locking), generally a chassis vehicle is used to carry the vacuum circuit breaker and realize Pushing in and out of the vacuum breaker. The structural design of the existing chassis car is unreasonable, and there are the following defects; [0003] 1. The interlocking mechanism ...

AI Technical Summary

Problems solved by technology

[0003] 1. The interlocking mechanism of the chassis car uses the left plate to assist the locking plate to realize the bouncing. The left plate is easy to wear and the bouncing of the locking plate is not sensitive. Potential safety hazards, likely to cause safety accidents

[0004] 2. When the frame of the chassis vehicle enters and exits the cabinet, the frame is prone to deflection, resulting in a relatively strong operation of the chassis vehicle, and the operation is not convenient enough
