Portal crane lock

Abstract

The invention discloses a portal crane lock. The portal crane lock comprises a lock body (2) fixed on an installation board, a lock board (6), a mobile rod (10), a swing rod (4) and a rotating hook (11). The lock board (6) is arranged in the lock body and can move up and down. The upper end of the lock board (6) is connected with a driving component. The mobile rod penetrates into the lock body, can slide left and right and is provided with a notch (12) through which the lock board (6) is inserted and drawn out. One end of the mobile rod is provided with a pin roll hole. The swing rod is articulated with the mobile rod through a shaft pin (3). The rotating hook located at one side of the lock body is connected with the swing rod through a pin roll (5). The rotating hook is provided with a U-shaped groove matched with the rotating body of a movable door. When the movable door is opened or closed, the rotating body strikes the U-shaped grove of the rotating hook (11) in the positive direction and the negative direction so that the U-shaped groove rotates in the positive direction and the negative direction and then the swing rod drives the mobile rod (10) to move left and right in order to open and close the lock. The invention is applied to the platform half-height safety door, mainly controls the locking and opening of the motion of the left movable door and the right movable door and can ensure the safe and reliable use of the platform movable door.

Description

technical field [0001] The invention relates to a door machine lock, in particular to a door machine lock used on a half-height safety door of a subway platform. Background technique [0002] Most of the existing subway platform safety doors use foreign door operator systems. The door operator locks equipped with the system are complex in structure, high in cost, and difficult to purchase separately, which restricts the development of subway platform security doors. Therefore, how to speed up the localization of the door operator system and design a door operator lock with a simple structure and easy operation is a technical problem that needs to be solved urgently in the industry. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, and to provide a door operator that can ensure that the left and right movable doors are locked after they are closed in place, regardless of whether the lef...
