SU420532A1 - LOCK OF THE SLIDING MINE DOOR ELEVATOR - Google Patents

Description

one

The invention relates to the elevator industry and can be used in the construction of the locks of the sliding doors of elevator shafts.

Known locks of sliding doors of elevator shafts, containing, mounted on the carriage of one of the valves, and edged w, an ekoldoy to the line of the gate gate, gateway, counterbalance, interacting with the carriage of the second leaflet, drive zash, trees and limit switches, controlling the porch of the sash and locking the lock, known device, the latch actuator is made in the form of a rotary mounted on the carriage carrying the latch, an angular lever, one shoulder of which is connected with the slide of the cannon door, and the other acts on oats latch.

However, the known design of the lock is relatively high in complexity and complexity of manufacturing the latch drive mechanism. The locking of each leaflet is controlled independently, and the moments of one contact actuation with the leafs closed and the second one not working. These contacts do not have a duplicating control system and, as a result, the reliability of the control for locking the valves is reduced.

The purpose of the invention is to increase reliability.

control lock and simplify the design of the lock of the shaft door.

This is achieved due to the fact that on the second carriage a rocking chair, acting when interacting with the latch, is pivotally mounted on the limit switches, and the latch drive is pulled out in the form of a counterbalance mounted at an angle of 3 ° b to the line of the hinge plate doors.

FIG. 1 shows the top beam of the mine door with shutters; in fig. 2 — node 1 in FIG. 1. Amok sliding elevator door mine

contains mounted on the carriage i of one of the flaps 2, the latch 3 with the counterweight 4, and the latch is turned with a cheek to the line of the iritvor flaps. On the counterbalance 4, a latch actuator is installed, made in the form of an angle 3-b to the anvil line of the leaflets of the plate 5. The latch 3 with its bolt falls down behind the stop 6 of the carriage 7 of the second flap and thereby keeps the flaps 2 in locked position. On the carriage 7 second

the hinge of the door hinge is mounted a rocking chair 8, interacting with its roller 9 with the push bar 10, which is made on the latch lever 3.

Rocking 8 also has in its upper part facing the end switches

And, the push bar 12, acting on the rod of the limit switch 11.

The device works in the following way.

When approaching the elevator car to the floor, the cabin door sash captures plate 5 and carries it in the direction of the door opening. At the same time, at the initial moment, plate 5 is rotated to a vertical position, i.e., to a position at which plate 5 begins to interact with the plane cabin door layer. Turning at an angle of 3-8 ° and zaned into a vertical position, the plate thereby rotates the latch 3 and unlocks the lock. The rocking chair 8 lowers into a viz and releases the rods of the limit switches 11, the elevator control circuit opens.

When closing the sash of the mine door, the cuttings bring the sash to the line of the vestibule and frees plate 5, under the action of the counterweight 4, the latch 3 with its latch sinks into the stop 6 of the carriage 7, while the pressure bar 10 acts on the roller 9 of the rocker 8

four

and its pressure bar 12 presses the rods of the limit switches 11. The elevator control circuit closes and the elevator is ready for operation.

Subject invention

Elevator sliding door of the elevator, which contains a counter-weight latch mounted on one of the carriages and facing the latch to the anvil line of the sash, interacting with the stop of the second carriage, actuating the latch and limit switches, in order to simplify the design and increase the reliability of controlling the sash , on the second carriage, a rocking chair is pivotally mounted, acting, when interacting with the latch, on the kick switches, and the latch drive is designed as mounted on the counterweight at an angle of 3-8 ° to the vestibule line of the plate folds.
