Background technology
when elevator carries out maintenance down, needing use safety apparatus for examination and repair to be fixed lift car, preventing its action when overhauling.Traditional safety overhauling device generally engages with cam engagement movable link, and must there be strict position relationship the engagement section of the engagement section of cam member, movable link, stationary member, otherwise the state of two position detecting switchs can not reflect the position of movable link well, make the design comparison of movable link complicated, and tooling cost is high.Secondly because needs rotate movable link, be engaged in the engagement section of stationary member by the engagement section of movable link, therefore operate cumbersome, cost is high again, and apparatus for controlling elevator becomes relative complex simultaneously.
Summary of the invention
the object of the invention is to, a kind of elevator safety apparatus for examination and repair is provided.The present invention is simple for structure, easy to operate, and advantage of lower cost.
technical scheme of the present invention: a kind of elevator safety apparatus for examination and repair, is characterized in: comprise the strap be fixed on car guide rail, and is fixed on the key seat on the upper beam of car; Be provided with maintenance pin in described key seat, described strap is provided with the jack corresponding with overhauling pin front end; Described key seat two ends are provided with pilot hole, the rear and front end of maintenance pin is all arranged in pilot hole, and maintenance pin is provided with circular cylinder elastic cotter and operative pin, and circular cylinder elastic cotter and operative pin are all positioned at inside key seat, and circular cylinder elastic cotter is in the position near maintenance pin front end, operative pin is in the position near maintenance pin rear end.
in above-mentioned elevator safety apparatus for examination and repair, the both ends open up and down of described key seat, and one of them sidewall is also provided with opening, be provided with permanent seat in a sidewall locations of opening, permanent seat is provided with two are established operative pin draw-in groove for card.
in aforesaid elevator safety apparatus for examination and repair, the rear end of described key seat is provided with inspection switch adapter plate, and inspection switch adapter plate is fixed with travel switch; That overhauls pin rear end is provided with groove, and groove is positioned on the sidewall of maintenance pin.
in aforesaid elevator safety apparatus for examination and repair, described strap is fixed on car guide rail by pressure guide plate.
in aforesaid elevator safety apparatus for examination and repair, when in the draw-in groove that operative pin is fastened on permanent seat rear end, the contact of described travel switch is positioned at the groove of maintenance pin; When in the draw-in groove that operative pin is fastened on permanent seat front end, the front end of described maintenance pin is plugged in the jack of strap.
compared with prior art, of the present invention simple for structure clear, safe and reliable, and simple to operate, advantage of lower cost.

fig. 2 is the structural representation of pin boss portion.
being labeled as in accompanying drawing: 1-presses guide plate, 2-car guide rail, 3-strap, 4-key seat, 5-circular cylinder elastic cotter, 6-permanent seat, 7-operative pin, 8-travel switch, and 9-overhauls pin, 10-inspection switch adapter plate, 11-upper beam.
Detailed description of the invention
below in conjunction with drawings and Examples, the present invention is further illustrated, but not as the foundation limited the present invention.
embodiment.A kind of elevator safety apparatus for examination and repair, as depicted in figs. 1 and 2: comprise the strap 3 be fixed on car guide rail 2, and is fixed on the key seat 4 on the upper beam 11 of car; Be provided with maintenance pin 9 in described key seat 4, described strap 3 is provided with the jack corresponding with overhauling pin 9 front end; Described key seat 4 two ends are provided with pilot hole, the rear and front end of maintenance pin 9 is all arranged in pilot hole, and maintenance pin 9 is provided with circular cylinder elastic cotter 5 and operative pin 7, and circular cylinder elastic cotter 5 and operative pin 7 are all positioned at inside key seat 4, and circular cylinder elastic cotter 5 is in the position near maintenance pin 9 front end, operative pin 7 is in the position near maintenance pin 9 rear end.The both ends open up and down of described key seat 4, and one of them sidewall is also provided with opening, be provided with permanent seat 6 in a sidewall locations of opening, permanent seat 6 is provided with two are established operative pin 7 draw-in groove for card.The rear end of described key seat 4 is provided with inspection switch adapter plate 10, inspection switch adapter plate 10 is fixed with travel switch 8; That overhauls pin 9 rear end is provided with groove, and groove is positioned on the sidewall of maintenance pin 9.Described strap 3 is fixed on car guide rail 2 by pressure guide plate 1.When in the draw-in groove that operative pin 7 is fastened on permanent seat 6 rear end, the contact of described travel switch 8 is positioned at the groove of maintenance pin 9; When in the draw-in groove that operative pin 7 is fastened on permanent seat 6 front end, the front end of described maintenance pin 9 is plugged in the jack of strap 3.
principle of work of the present invention: when elevator normally works, operative pin 7 is fastened in the draw-in groove of permanent seat 6 rear end, and now overhauling the front end of pin 9 is the jacks departing from strap 3, and therefore lift car can free up-and-down movement; And when elevator overhauls, after car is fixing, rotatable pin 7, makes it depart from draw-in groove, then forward end promotes maintenance pin 9, and maintenance pin 9 front end is inserted in the jack of strap 3, and then rotating operation pin 7 makes in its draw-in groove snapping in permanent seat 6 front end.When overhauling, owing to overhauling the rotation of pin 9, groove is produced in travel switch 8 contact being previously positioned at groove, and now trigger switch activation, enters maintenance model.
