Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Example one

Referring to fig. 1 and 3, the fall-prevention safety straight elevator in this embodiment includes an elevator shaft 1, an elevator car 2 disposed in an inner cavity of the elevator shaft 1, and a traction machine disposed on the top of the elevator shaft 1 to drive the elevator car 2 to ascend and descend, and the traction machine drives the elevator car 2 to ascend and descend through a traction machine steel wire rope 3. Wherein:

electromagnetic locking locks 4 are respectively installed at two side edges of the top of the elevator cage 2, and each electromagnetic locking lock 4 comprises a guide sleeve 41, a locking column 42 movably inserted into the inner cavity of the guide sleeve 41, an electromagnet fixedly arranged at the tail end of the guide sleeve 41 and an elastic device arranged in the inner cavity of the guide sleeve 41 and used for pushing the locking column 42 to pop up. The electromagnet comprises an iron core 44 and a wire winding 45 wound outside the iron core 44, and the power on and off of the wire winding 45 are controlled by a controller for controlling the operation of the elevator. The elastic device is a spring 43, one end of the spring 43 is fixedly assembled on the iron core 44, and the other end of the spring 43 is fixedly connected with the tail end of the lock cylinder 42.

And locking grooves 5 are respectively arranged at each floor on the side wall of the elevator shaft 1, and when the elevator car 2 stops, the lock columns 42 of the electromagnetic locking locks 4 can be correspondingly inserted and locked into the locking grooves 5.

When the elevator cage 2 stops, the controller controls the lead winding 45 to be powered off, at the moment, the iron core 44 disappears due to the magnetic force of the power-off, the lock column 42 pops out under the elastic action of the spring 43 and is inserted into the corresponding locking groove 5 in a locking mode, and the elevator cage 2 is prevented from falling. After the passengers enter or exit, the controller controls the door of the elevator door to be closed and simultaneously conducts the circuit of the wire winding 45, the iron core 44 is electrified to generate magnetic force, the lock column 42 is sucked back into the inner cavity of the guide sleeve 41, and the elevator cage 2 is lifted normally.

In order to prevent the elevator cage 2 from falling due to the breakage of the traction machine steel wire rope 3, an emergency anti-falling switch is installed in the elevator cage 2 and controls the electrification and the outage of the electromagnetic locking lock 4. When people who take the elevator perceive that the elevator cage 2 falls abnormally, the emergency anti-falling switch is pressed, at the moment, the wire winding 45 is powered off, the iron core 44 disappears due to the power-off magnetic force, the lock column 42 pops out under the elastic force action of the spring 43 and is inserted into the locking groove 5 below the lock column 42, and the elevator cage 2 is prevented from falling continuously. The emergency anti-falling switch is pressed down until the elevator cage 2 stops falling, the maximum falling distance of the elevator cage 2 is the height of one floor, and the safety of personnel in the elevator cage 2 can be effectively ensured.

In order to prevent noise generated by friction between the lock cylinder 42 and the side wall of the elevator shaft 1 during the falling, a silent roller 46 is mounted at the front end of the lock cylinder 42.

In order to prevent a large impact sound from being generated between the lock cylinder 42 and the side wall of the elevator shaft 1 when the lock cylinder is ejected, a silencing rubber strip 51 is attached to the side wall of the elevator shaft 1 corresponding to the locking groove 5. Meanwhile, the silent rubber strip 51 can buffer the impact between the lock column 42 and the sidewall of the elevator hoistway 1, and is beneficial to protecting the electromagnetic locking lock 4 and the locking groove 5.

The top surface of the locking groove 5 is designed to be an inclined surface. When falling, the lock column 42 enters the locking groove 5 from the inclined plane, so that the impact between the lock column 42 and the side wall of the elevator shaft 1 can be buffered, and the electromagnetic locking lock 4 and the locking groove 5 are protected.

To absorb the downward impact of the cage 2 during a fall, a cushion rubber block 52 is provided on the bottom surface of the locking groove 5.

The utility model discloses in guide sleeve 41, lock cylinder 42 and spring 43 all adopt diamagnetic material to make, avoid influencing its function because of receiving the electromagnet.
