A loc mechanism for a vehicle body frame of a through-road

Abstract

A loc mechanism for a vehicle body frame of a through-road comprises a vehicle body frame and a butt joint frame As the core components of the whole locking mechanism, the vehicle body frame comprisea car body frame, a connecting rod, a car body frame sealing strip, a guide seat, a positioning pin, a handle, a base, a mounting bolt, a combined seal gasket and a car body fastener, and the car bodyframe is pre-fixed on the end surface of the car body through the car body fastener; The docking frame is formed to provide a fixed connection interface for the locking mechanism, and is located on the end face of the through channel, and comprises a docking frame, a rotating shaft, a fixed shaft, a push-pull handle and a docking frame sealing strip. 12 loc hooks and that rotate shaft on the buttjoint frame are driven to be matched or separated by pulling two handle, so that the through-way and the end face of the car body are quickly connected and unknitted, the operation is convenient andquick, and the maintenance efficiency of the through-way is improved.

Description

technical field [0001] The invention relates to the field of passageways for vehicles such as subways, urban rails, and light rails, and in particular to a body frame locking mechanism for the passageways. Background technique [0002] With the rapid development of urban rail passenger cars and other rail vehicles, the number of urban rail passenger cars has increased rapidly, and the requirements for vehicle maintenance and repair efficiency are also getting higher and higher. As an important part of the car body connection, the through channel is installed at the junction of two carriages to play the role of connection and transition. The bellows assembly of the through channel is connected with the car bodies at both ends through the bellows end frame and the car body frame through several through channel end frame locking mechanisms. How to quickly connect and detach the through channel from the vehicle body is an important factor affecting the efficiency of vehicle bod...

AI Technical Summary

Problems solved by technology

The traditional way of connecting the two sides of the through passage to the car body is to fasten with bolts or to fix with multiple independent lock bolts. When disassembling the two compartments of the passenger car, the disassembly of the through passage requires dismantling dozens of bolts or pulling more than ten lock bolts. , so that the through channel can be separated from the vehicle end, the dismantling time is too long and the operation is inconvenient
