Abstract
The invention relates to an elevator anti-rolling device which comprises a barrier strip, a limiting column, a normally closed switch and a spring, is arranged at the upper end of an elevator car door device and the lower end of a car toe guard when an elevator is installed and maintained, and is applied to safety protection when the elevator is installed and maintained.
Description
1, technical field
The invention belongs to a kind of elevator, particularly a kind of elevator rolling-proof device.
2, background technology
At present, elevator has circuit and mechanical chain protection at its safety guard-safeguard that puts into operation, but in installation and maintenance process; its safety system was not normally used; ascending for elevator or descending process often take place, will run over and injure the personnel of hoistway work, the safety responsibility accident takes place.
3, summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of elevator rolling-proof device, and it is simple in structure, reliable operation.
The present invention solves the technical scheme that its technical matters takes: be made up of blend stop, limited post, normally closed switch and spring, when elevator is installed and keeped in repair, be installed in the upper end of elevator cage door device and the lower end of car toeguard.
The invention has the beneficial effects as follows simple in structurely, install and install and use during maintenance at elevator, convenient and reliable.
4, description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Figure is a kind of elevator rolling-proof device scheme drawing
Among the figure: 1. blend stop 2. limited posts 3. normally closed switchs 4. springs
5, the specific embodiment
The specific embodiment:
In the drawings, form by blend stop (1), limited post (2), spring (4) and normally closed switch (3), blend stop (1) has endoporus and limited post (2) free-running fit, blend stop (1) is moved along limited post (2), and blend stop under the normal circumstances (1) does not contact with normally closed switch (3), and the elevator power supply connects the road, as obstacle compression blend stop (1), blend stop (1) moves, and compression normally closed switch (3) makes normally closed switch (3) cut off the elevator motor power supply in the normally open position.
When elevator was installed and keeped in repair, rolling-proof device was installed in the upper end of elevator cage door device and the lower end of car toeguard.
Claims (2)
1. an elevator rolling-proof device is characterized in that being made up of blend stop, limited post, normally closed switch and spring.
2. according to a kind of elevator rolling-proof device described in the claim 1, when it is characterized in that elevator installed and keep in repair, be installed in the upper end of elevator cage door device and the lower end of car toeguard.
