Abstract
The invention discloses a lifting system for lifts, which comprises windlasses, controllers and a wire rope, the operation of the windlasses is controlled by the controllers, the wire rope is wound on the windlasses, a lift car is hung on one end of the wire rope through a pulley on the lift car, and a counterweight is hung on the other end of the wire rope through a pulley on the counterweight. The lifting system is characterized in that: each controller comprises a standby power device with an independent power supply, the standby power device is provided with an electromagnetic clutch, and the output shaft of the electromagnetic clutch is coaxial with the input shaft of the gearbox of the windlass; at the moment when the power fails, the controllers can start up the standby power devices, and thereby the standby power devices drive the drums of the windlasses to rotate. Since the lifting system adopts the standby power devices, the lifting system cannot be affected by power failure, and thereby the safety performance of a running lift is enhanced.
Description
Technical field
The present invention relates to a kind of jacking equipment, be specifically related to a kind of elevator jacking equipment.
Background technology
Existing elevator jacking equipment, normally control the motion of stretching to control cage of steel rope by winch, be the patent of invention of CN1522220A such as publication number, a kind of lift appliance lifting mechanism, it comprises 2 groups of winchs, control respectively the control setup of 2 groups of winchs and be wound on 2 groups of steel ropes on the winch, 1 position in 2 positions of described wire rope grip between 2 groups of winchs is wound onto on the pulley of cage, and suspention cage, be wound onto on the pulley of bob-weight in other 1 part, the suspention bob-weight, it has solved because of the former of the inspection of working service etc. or fault thereby the problem that causes the revolution of winch to stop, improved usage safety performance, but occuring in the situation of outage suddenly, because the impulsive force that the cut of winch brings, the potential safety hazard of bringing still do not solve.
Summary of the invention
Technical matters to be solved by this invention provides the elevator jacking equipment that a kind of hoisting depth is unrestricted, safety performance is good.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
The elevator jacking equipment, comprise winch, the control setup and the steel rope that is wound on the winch of the operation of control winch, one end of described steel rope is by the suspention of the pulley on cage cage, the other end is by the suspention of the pulley on bob-weight bob-weight, described control setup comprises the standby power device with independent current source, this standby power device is provided with magnetic clutch, the input shaft of the output shaft of this magnetic clutch and the change speed gear box of winch is coaxial setting, in the moment that outage occurs, control setup starts the standby power device, and the standby power device drives the reel rotation of winch.When suddenly outage occured, it started the driving engine of standby power device under the effect of control setup, and magnetic clutch combination, magnetic clutch drive the change speed gear box running of winch, and then drive the reel rotation of winch, elevator normally moves, the impact that can not be cut off the power supply.
Further preferred, described magnetic clutch can be for cutting off the power supply in conjunction with magnetic clutch.
Further preferred, described winch can be 2 groups, control setup is 2 operations of controlling respectively 2 groups of winchs, be equipped with the standby power device in each control setup, described wire rope roll is on 2 groups of winchs, suspend cage in midair by the pulley on the cage on 1 position in 2 positions of wire rope grip between 2 groups of winchs, and the suspention cage, on other 1 part, suspend bob-weight in midair by the pulley on the bob-weight.
Compared with prior art, the present invention has the following advantages:
1, adopts the standby power device, when suddenly outage occurs, it is under the effect of control setup, start the driving engine of standby power device, and the magnetic clutch combination, magnetic clutch drives the change speed gear box running of winch, and then the reel that drives winch rotates, elevator normally moves, and the impact that can not be cut off the power supply improves elevator Operation safety energy.
2, solved because of the former of the inspection of working service etc. or fault thereby the problem that causes the revolution of winch to stop, improved usage safety performance.
Description of drawings
Fig. 1 is the structural representation that a kind of elevator of the present invention is used jacking equipment.
