Door lock device of safety door system of interurban railway station

Abstract

The invention discloses a door lock device of a safety door system of an interurban railway station. The door lock device comprises a supporting plate capable of doing linear motion along with a sliding door, wherein a collision column is arranged on the supporting plate; the collision column and a locking and clamping plate form a cam mechanism; an unlocking device is arranged on the cam mechanism. The door lock device can realize functions such as automatic locking, automatic unlocking, manual unlocking and 'door position arriving and locking' position detection of the sliding door of the safety door system of the station. The door lock device has the advantages that on the premise of guaranteeing the function of the door lock device, the number of parts with high motion frequencies is reduced, the structure is simple, and the safe reliability is greatly improved; furthermore, the locking and clamping plate is not connected with an electromagnet, so that the phenomenon that an iron core is locked in an automatic unlocking process is avoided, and thus the requirement on the environment of the interurban railway station can be completely met. By the adoption of a manual unlocking device with a roller and steel wire rope structure, the manual unlocking force is greatly reduced, and the technical index requirement that the manual unlocking force is not greater than 67N can be met, so that an active effect on batch application is achieved.

Description

technical field [0001] The invention relates to a safety door lock device, in particular to a door lock device applied in an intercity railway platform safety door system. Background technique [0002] The intercity railway platform safety door system is a platform equipment with higher environmental requirements and more stringent technical requirements than the subway safety door system. Its main function is to effectively isolate passengers from the train and ensure the safety of passengers. The intercity railway platform safety door system mainly involves mechanical, electrical, software and other technologies. Among them, the door lock device is an important core module to ensure the realization of the main functions of the intercity railway platform safety door system. Therefore, the safety and stability of the door lock device, whether it can adapt to intercity The environmental requirements of the railway platform are the most important factors for the realization of...

AI Technical Summary

Problems solved by technology

At present, there is no door lock device specially applied to the safety door system of the intercity railway platform. The safety door lock device used on the subway mainly has the following problems and deficiencies: (1) The structure is complex, the safety and stability are low, and it is difficult to adapt to the environment of the intercity railway platform Requirement (2) The manual unlocking force is not greater than 67N, and this technical index is not easy to be guaranteed
