Abstract
The invention relates to a telescopic lift car toe guard which comprises an upper expansion plate, a lower expansion plate, a chute and a safety pin. The upper expansion plate and the lower expansion plate are of a rectangular structure; the chute is of a U-shaped structure; the chute is fixedly connected to both sides of the front side of the upper expansion plate; the lower expansion plate sleeves in the chute; a detection switch is arranged at the top end of the upper expansion plate; a detection switch baffle plate is arranged at the top end of the lower expansion plate; a triangle lock catch is arranged at the top end of the upper expansion plate; a triangle lock bar is arranged at the top end of the lower expansion plate; the lower end of the upper expansion plate is provided with a plurality of round through holes; the upper end of the upper expansion plate is provided with a plurality of round through holes. The telescopic lift car toe guard has the benefits that in the overhauling process, the toe guard extends, so that the area of the toe guard is increased and safety of overhauling is improved. When an elevator normally operates, the toe guard is retracted and is locked and the retracted toe guard can be used for effectively reducing the depth of a pit.
Description
technical field:
The present invention is foot protecting plate device, belongs to elevator technology field.
background technology:
in elevator industry, often needing to overhaul elevator, but likely can something unexpected happened in overhauling elevator process, needing to adopt toe guard of elevator car for damaging personnel when avoiding something unexpected happened, improve safety during maintenance, and can pit depth be reduced simultaneously.
summary of the invention:
Technical matters to be solved by this invention is: provide a kind of telescopic toe guard of elevator car, to improve maintenance safety and to reduce pit depth.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of flexible toe guard of elevator car, include expansion plate, lower expansion plate, chute and latch, described upper expansion plate and lower expansion plate are rectangular configuration, the U-shaped structure of described chute.
In order to connect lower expansion plate, further, described chute is fixedly connected on the both sides in expansion plate front, and described lower expansion plate cover enters in described chute.
Position is not got back in order to prevent lower expansion plate, further, the top of described upper expansion plate is provided with detector switch, and the top of described lower expansion plate is provided with detector switch block, the top of described upper expansion plate is provided with triangle snap close, and the top of described lower expansion plate is provided with triangle locking bar.
Conveniently use latch, further, the lower end of described upper expansion plate is provided with multiple manhole, and the upper end of described upper expansion plate is provided with multiple manhole.
Compared with prior art, usefulness of the present invention is: make toeguard stretch during maintenance, increases the area of toeguard, improves the safety of maintenance.When elevator normally runs, regain toeguard, and pin, the toeguard after withdrawal, can pit depth be effectively reduced.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is axonometric drawing of the present invention.
In figure: 1, upper expansion plate; 2, lower expansion plate; 3, chute; 4, latch; 5, detector switch; 6, detector switch block; 7, triangle snap close; 8, triangle locking bar; 9, manhole.
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
One according to Fig. 1 is stretched toe guard of elevator car, include expansion plate 1, lower expansion plate 2, chute 3 and latch 4, described upper expansion plate 1 and lower expansion plate 2 are rectangular configuration, the U-shaped structure of described chute 3, described chute 3 is fixedly connected on the both sides in expansion plate 1 front, described lower expansion plate 2 cover enters in described chute 3, the top of described upper expansion plate 1 is provided with detector switch 5, the top of described lower expansion plate 2 is provided with detector switch block 6, the top of described upper expansion plate 1 is provided with triangle snap close 7, the top of described lower expansion plate 2 is provided with triangle locking bar 8, the lower end of described upper expansion plate 1 is provided with multiple manhole 9, the upper end of described upper expansion plate 1 is provided with multiple manhole 9.
When elevator needs maintenance, open triangle snap close 7, put down lower expansion plate 2, the manhole 9 on lower expansion plate 2 is allowed to align with the manhole 9 on upper expansion plate, plug latch 4,, now detector switch block 6 and detector switch 5 are separated, and whole elevator controlling part is obstructed, elevator is in can not state of kinematic motion, when overhauling elevator is complete, pull out latch 4, lower expansion plate 2 is pushed to, lock triangle snap close 7, now detector switch block 6 and detector switch 5 are collided, and the circuit ON of whole elevator, now elevator just can normally run.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
