Abstract

The invention discloses a locking mechanism for a switch machine. The locking mechanism for the switch machine comprises locking iron, an action rod, an action block, a lock block group, an oil cylinder assembly and a damping mechanism. Two grooves are formed in one side of the locking iron. Two sliding grooves and two locking blocks which are of a diamond structure are arranged on the action block, and the action rod is fixedly connected with the action block. One side of the action block is in sliding contact with the locking iron, and the other side of the action block is in sliding contactwith an outer cylinder sleeve of the oil cylinder assembly. The damping mechanism is arranged between the locking iron and the outer cylinder sleeve. According to the locking mechanism for the switchmachine, the locking mode of an existing locking mechanism for the switch machine is improved, and the locking stability and reliability are improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a locking mechanism for a switch machine. Background technique [0002] The switch machine is an important railway turnout switching equipment, its function is to switch and lock the turnout, change the opening direction of the turnout, and supervise and check the position of the turnout. The switch machine is an important guarantee to ensure the safety of railway traffic and improve transportation efficiency. [0003] The locking mechanism is a key component in the switch machine. The switch machine realizes the locking of the turnout through the locking mechanism. The reference document CN104494647A describes the commonly used locking mechanism of the switch machine in China. In this locking method, the lock block rotates around the pin shaft, and the force between the locking iron, the action rod and the lock block changes continuously during the switchover p...
