Locking mechanism for switch machine

Abstract

The invention discloses a locking mechanism for a switch machine, which belongs to the technical field of switch machines, and comprises a locking body which sleeves an action rod and is connected with the action rod through a squeezing cutting and stripping assembly, and a lock hook which is arranged on the inner wall of a box body of the switch machine and can realize a locking action with the locking body; an insertion hole for the lock hook to be inserted is horizontally formed in the locking body in the moving direction of the action rod, a through hole for the shifting plate to penetrate through is formed in the locking body, the insertion hole and the through hole are communicated through a communicating hole, and a locking roller capable of moving up and down in the communicating hole is arranged in the communicating hole; a stop block used for limiting the locking roller is arranged in the locking body and located above the locking roller, a groove matched with the locking roller is formed in the front end of the lock hook, it is guaranteed that the locking action of the action rod is effective and reliable, and the stability and reliability of equipment are improved; and the extrusion cutting can be protected, the abnormal fracture phenomenon is avoided, and the fracture indication function is achieved.

Description

technical field [0001] The invention belongs to the technical field of switch machines, and in particular relates to a locking mechanism for a switch machine. Background technique [0002] The switch machine refers to an important basic signal equipment used to reliably switch the position of the switch, change the opening direction of the switch, lock the rail of the switch, and reflect the position of the switch. It can well ensure driving safety, improve transportation efficiency, and improve driving personnel. labor intensity. The locking mechanism set on the action bar in the switch machine is used to ensure that the action bar is locked when it moves to both ends, and the existing locking mechanism cannot guarantee that the action bar is locked at both ends. Effective and reliable closing; a squeeze cutting is arranged between the existing locking mechanism and the action rod, so as to protect the switch machine from being damaged when the switch is squeezed or the in...

AI Technical Summary

Problems solved by technology

However, during the use of the switch machine, due to the direct stress on the squeeze pin, the train wheels vibrate when passing by, and the squeeze pin is in a state of vibration and wear for a long time, which is prone to abnormal fracture, and the normal operation of the switch machine cannot be guaranteed.
