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 purpose of the utility model is to provide one kind can prevent carriage tenesmus, again overhauling elevator safety dress easy to use
It sets.
To achieve the above object, the technical solution of the utility model is: a kind of safety device for overhaul of elevator, including is mounted on
The buffer unit of lift car bottom and the limiting device being mounted on guide rail, the limiting device include barrier plate, limit
Plate, shaft, first switch, second switch, bracket, the first trigger member, the second trigger member and returning spring；The bracket is fixed
On guide rail, have elongated slot, hole seat and limit base；The barrier plate is in long strip, and mutually connects firmly with limit plate, barrier plate
It is mutually connected firmly with shaft, shaft is matched with hole seat.When elevator is in normal operating conditions, effect 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
First switch, it is ensured that elevator is in inspecting state, then 90 ° of rotating shafts, and barrier plate is climbed over and is in a horizontal state from elongated slot,
At this point, the second trigger member triggers second switch, and safety device for overhaul of elevator signal in place is sent to elevator device, limits board
It on the downside of limit base, prevents barrier plate from turning up, reaches and prevent 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.
The advantages of technical solutions of the utility model and good effect are: when overhauling elevator, first pulling out shaft, then
90 ° of rotating shafts, barrier plate are climbed over and are in a horizontal state from elongated slot, and limit plate is stuck on the downside of limit base, i.e., reachable to prevent
Carriage tenesmus purpose.In the process, the first trigger member touches first switch, it can be ensured that elevator is in inspecting state, stops
Plate in place after, the second trigger member can trigger second switch again, and send safety device for overhaul of elevator signal in place to elevator device,
Ensure the safety of maintenance personal.

Specific embodiment
In the following, being illustrated based on attached drawing to the embodiments of the present invention.
As shown in Figure 1, Figure 2 and shown in Fig. 3, a kind of safety device for overhaul of elevator, it is characterised in that: including being mounted on elevator car
The buffer unit (1) of compartment (100) bottom and the limiting device (2) being mounted on guide rail (101), the limiting device include resistance
Baffle (21), limit plate (22), shaft (23), first switch (24), second switch (25), bracket (26), the first trigger member
(231), the second trigger member (221), returning spring (27) and support plate (28)；
The bracket (26) is fixed on guide rail, has elongated slot (261), hole seat (262) and limit base (263)；Institute
It is in long strip to state barrier plate (21), and is mutually connected firmly with limit plate (22), barrier plate (21) is mutually connected firmly with shaft (23), shaft (23)
