Embodiment 1

[0022] Such as Figure 1-Figure 4 As shown, the electric locking device for full-height platform doors of the present invention includes an electromagnet mounting plate 1, an electromagnet assembly 2, a connecting shaft 3, a lock plate 4, a left door lock pin 5, a left door lock pin bracket 6, Right door lock pin 7, right door lock pin bracket 8 and manual unlocking plate 9, one side of the electromagnet mounting plate 1 is installed in the middle of the upper frame of the full-height platform door, and the electromagnet assembly 2 is fixed on the electromagnet mounting plate On the other side of 1, the armature below the electromagnet assembly 2 is connected to the lock plate 4 through the connecting shaft 3, and controls the lock plate 4 to move upward, so that the lock plate 4 releases the lock pin 5 of the left door and the lock pin 7 of the right door. The locking of the left and right sliding doors of the full-height platform door can be realized automatically; On the l...

Embodiment 2

[0031] The electromagnet assembly 2 can be replaced by a micromotor assembly, and the micromotor drives the upward movement of the lock plate 4. The working principle of other components is the same as that described in Embodiment 1, thereby realizing the function of the electric locking device.

Embodiment 3

[0033] In contrast to the working principle of the electric locking device in Example 1, the lock in-position detection switch 10 and the door in-position detection switch 11 are photoelectric switches, which replace the proximity switch in Embodiment 1, and trigger the switch action through photoelectric detection. The working principle is the same as that described in Embodiment 1, so as to realize the function of the electric locking device.

Abstract

The invention discloses an electric locking device for a full-height platform door. An electromagnet assembly or other driving assemblies are used for driving a lock plate to move, and the lock plate and lock pins installed on sliding doors are combined to form a working state. In the door opening process, an electromagnet drives the lock plate to move to remove locking to the lock pins, and thus the sliding doors are in an openable state; in the sliding door closing process, the lock pins push the lock plate to move under the action of door closing force, after the sliding doors are closed in place, the lock pins are locked by the lock plate, and thus the sliding doors are in a locked state. A manual unlocking plate is arranged, the lock plate is manually driven to move to remove locking to the lock pins, and thus the sliding doors are in an openable state. The electric locking device is simple in structure and high in function integration level; an automatic locking in-place detection device and a manual unlocking in-place detection device are integrated, and the electromagnet assembly is in a working state only in the door opening process; the electric locking device is convenient to install and adjust, high in adjusting adaptability and reliability and low in cost and has good application prospects.

Description

technical field [0001] The invention relates to an electric locking device for a full-height platform door, belonging to the technical field of platform door systems. Background technique [0002] At present, the full-height platform door electric locking device used in the rail transit platform door system or rapid transit platform door system on the market uses an electromagnet to drive the lock pin to move, and the lock pin is combined with the lock block installed on the sliding door to form a locking relationship. Specifically, when the door is opened, the electromagnet drives the lock pin to move, unlocking the lock pin to the lock block, so that the sliding door of the full-height platform door can be opened; when closing the door, before the sliding door of the full-height platform door closes in place, the electromagnetic The iron drives the lock pin to move, so that the sliding door can be closed in place; after the sliding door of the full-height platform door is ...
