Description
Technical field
The present invention relates to elevator safety technical field more particularly to a kind of safety device for overhaul of elevator.
Background technique
Elevator is overhauled and is safeguarded during routine use as delivery vehicle.And some are safeguarded, need to tie up
The personnel of repairing, which enter, carries out operation in elevator pit, cause the life security of maintenance personal to prevent elevator from inadvertently falling off, common
Safety measure is that buffer and clump are arranged in pit.For the elevator shallower for low hole, such method is simultaneously infeasible.
It is existing that patent of invention ZL2016104569699 has been authorized to propose a kind of emergency staircase of live ladder maintenance prevention device, it leads
It is fixedly connected with limit plate on rail, mounting plate is connected on lift car, is distributed vertically there are two settings on the limit plate
Deck, the side of deck, which is equipped with, to be open, and is connected with shaft by through-hole on the mounting plate, the both ends of shaft are connected separately with handle
Hand and locking level, in maintenance, locking level is pushed into deck, and carriage tenesmus can be effectively prevented.This technical solution is passed through with current
Bolt-type overhauling elevator prevent device it is the same, require by carriage run in place, axis hole alignment, can use, it is more troublesome.
Thus, develop one kind can prevent carriage tenesmus, again safety device for overhaul of elevator easy to use be necessary.
Summary of the invention
The object of the present invention is to provide one kind can prevent carriage tenesmus, again safety device for overhaul of elevator easy to use.
To achieve the above object, the first technical solution of the invention is: a kind of safety device for overhaul of elevator, including installation

Position plate, shaft, first switch, second switch, bracket, the first trigger member, the second trigger member and returning spring；The bracket is solid
It is scheduled on guide rail, has elongated slot, hole seat and limit base；The barrier plate is in long strip, and mutually connects firmly with limit plate, stops
Plate is mutually connected firmly with shaft, and shaft is matched with hole seat.When elevator is in normal operating conditions, work of the barrier plate in returning spring
Under, the state inconsistent and in a vertical shape with bracket.When elevator needs to overhaul, shaft is first pulled out, touches the first trigger member
Dynamic first switch, it is ensured that elevator is in inspecting state, then 90 ° of rotating shafts, and barrier plate climbs over and horizontal from elongated slot
State at this point, the second trigger member triggers second switch, and sends safety device for overhaul of elevator signal in place, limit to elevator device
Board prevents barrier plate from turning up on the downside of limit base, reaches and prevents carriage tenesmus purpose.
Preferably, first trigger member is a circular conical surface, it is made of one with shaft.
Preferably, second trigger member is an inclined-plane, it is made of one with limit plate.
Preferably, the buffer unit includes cushion and support.
Preferably, being also configured with handle in the shaft.
Preferably, the bracket is also equipped with card slot, card slot is connected with the elongated slot.When barrier plate is climbed over from elongated slot
90 ° and when being in a horizontal state, barrier plate is pushed into card slot along shaft axis direction, prevents from stopping board reversal.
Second of technical solution of the invention is: a kind of safety device for overhaul of elevator, including is mounted on lift car bottom
Buffer unit and the electronic prevention device that is mounted on guide rail, the electronic prevention device includes driving mechanism, prevention machine
Structure, first stroke switch, second stroke switch, pedestal；The driving mechanism has a rotary shaft, prevent mechanism have bar and
