Abstract

The utility model provides an elevator with anti -falling device, including car, lift passageway, anti -falling device and controller, the car is located the lift passageway, the top of car is connected with the rope, anti -falling device is fixed to be set up in the recess of car both sides face, anti -falling device includes cylinder and friction plate, the fixed piston rod that sets up at the cylinder of friction plate stretches out the end, the cylinder is connected with the controller electricity, the friction plate is with lift passageway inner wall parallel arrangement and have certain distance, top one side of car is provided with the overspeed governor, the overspeed governor is connected with the controller electricity, detects elevator operation speed signal feedback to controller through the overspeed governor. Elevator with anti -falling device can be when the elevator falls, drive the friction plate through the cylinder and remove, the friction plate that the symmetry set up is tightly pushing up lift passageway inner wall and is not droing, simple structure improves elevator factor of safety, terraced personnel's safety is taken advantage of in the guarantee.

Description

A kind of elevator with falling proof device
Technical field
The utility model belongs to elevators field, especially relates to a kind of elevator with falling proof device.
Background technology
The vertical conveyor of elevator to be a kind of with electrical motor be power, is equipped with box like gondola, takes advantage of people or carrying goods for tier building.Elevator, as the walking-replacing tool of skyscraper, brings great convenience to the life of people, but meanwhile takes elevator and also contain very large risk.Elevator all can be had to fall every year, and personal casualty; Current most of elevator adopts mechanical fall protection equipment, but mechanical protecting device safety factor is low, and needs artificially to overhaul frequently, not only brings trouble to use, and causes the wasting of resources.
Summary of the invention
In view of this, the utility model is intended to propose a kind of elevator with falling proof device, to prevent used during elevator falling, improves the safety factor of elevator.
For achieving the above object, the technical solution of the utility model is achieved in that
With an elevator for falling proof device, comprise car, hoist trunk, falling proof device and controller, described car is positioned at hoist trunk, and the top of described car is connected with rope, and described falling proof device is fixedly installed in the groove of car two sides;
Described falling proof device comprises cylinder and friction plate, and described friction plate is fixedly installed on the piston rod external part of cylinder, and described cylinder is electrically connected with controller, and cylinder receives the command signal of controller transmission and performs an action; Described friction plate and hoist trunk inwall be arranged in parallel, and have certain distance;
The side, top of described car is provided with velocity limiter, and described velocity limiter is electrically connected with controller, by velocity limiter detection elevator speed and signal feedback to controller.
Further, described car has steel plate to form.
Further, described hoist trunk is made up of steel plate, and the steel plate inwall of described hoist trunk is provided with friction layer.
Further, communication device is provided with in described car.
Further, the crown center position of described car has through hole, described through hole internal fixtion is provided with guard, realize being communicated with of car and hoist trunk, in case when there is unexpected situation, there is anoxic conditions in car, and prevent above car, having foreign material accidentally to fall in car by guard and injure boarding personnel by a crashing object.
Relative to prior art, elevator with falling proof device described in the utility model can when used during elevator falling, friction plate is driven to move by cylinder, symmetrically arranged friction plate presses closer hoist trunk inwall and does not come off, structure is simple, improve elevator safety coefficient, ensure the safety of boarding personnel.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation described in the utility model embodiment.
Description of reference numerals:
1-wall, 2-friction layer, 3-car, 4-cylinder, 5-fender, 6-velocity limiter, 7-hoist trunk, 8-guard.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
A kind of elevator with falling proof device as shown in Figure 1, comprise car 3, hoist trunk 7, falling proof device and controller, described car 3 is positioned at hoist trunk 7, and the top of described car 3 is connected with rope 1, and described falling proof device is fixedly installed in the groove of car 3 two sides; Described falling proof device comprises cylinder 4 and friction plate 5, and described friction plate 5 is fixedly installed on the piston rod external part of cylinder 4, and described cylinder 4 is electrically connected with controller, and described friction plate 5 be arranged in parallel with hoist trunk 7 inwall, and has certain distance; The side, top of described car 3 is provided with velocity limiter 6, and described velocity limiter 6 is electrically connected with controller, by velocity limiter detection elevator speed and signal feedback to controller.
Described car 3 has steel plate to form.
Described hoist trunk 7 is made up of steel plate, and the steel plate inwall of described hoist trunk 7 is provided with friction layer 2.
Communication device is provided with in described car 3.
The crown center position of described car 3 has through hole, described through hole internal fixtion is provided with guard 8, realizes being communicated with, in case when there is unexpected situation of car and hoist trunk, there is anoxic conditions in car, and prevent above car, having foreign material accidentally to fall in car by guard and injure boarding personnel by a crashing object.
When running velocity exceedes set elevator normal operational limits value, controller will send command signal to cylinder 4, cylinder 4 drives friction plate 5 to move to the direction near hoist trunk 7 inwall, and slowed down by friction plate 5 and friction layer 2, because the pressure between friction plate 5 and friction layer 2 constantly becomes large, friction force also constantly becomes large, finally makes elevator can rest on a certain position.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
