Abstract
The invention particularly relates to an emergency braking device for an elevator, and solves the existing problem of safety accidents caused by falling of the elevator under emergency circumstances. The emergency braking device for the elevator comprises braking blocks which are arranged on cylindrical guide rails in a penetrating manner, wherein braking friction plates are arranged in each braking block, the back parts of the braking friction plates are connected with pistons, and a speed sensor and an acceleration sensor are also arranged in each braking block; two rows of fixing plates are arranged on the outer side of the back of an elevator car, a conductive plate is arranged between the two rows of the fixing plates, multiple groups of permanent magnets with opposite polarities are arranged on the inner sides of the two rows of the fixing plates, and an induction coil is arranged in the conductive plate; a main controller is arranged at the top of the elevator car; a hydraulic pump is arranged at the bottom of the elevator car, and the hydraulic pump is connected to the pistons through a hydraulic pipeline; the main controller is connected to all the conductive plate, the hydraulic pump, the speed sensor and the acceleration sensor, and the conductive plate is also connected with the hydraulic pump. The emergency braking device disclosed by the invention has the advantages of simple structure, high safety and effectiveness, and on the premise that the normal operation of the elevator is not influenced, the situation that the elevator is braked under the emergency circumstances such as power failure and the like can be realized.
Description
Technical field
The present invention relates to lift facility, be specially a kind of elevator emergency brake device.
Background technology
The elevator brake used at present is all placed in the machine room of well headroom, when car rests in bay-lift place, is used for ensureing that elevator car safety is stopped.When being in emergency situation, as brake plate friction coefficient reduces, cable breaks etc., car loses its tractive force and hurtles down, and threatens to the life security taking elevator personnel.
Summary of the invention
The present invention causes the problem of safety misadventure in order to solve existing in emergency circumstances used during elevator falling, provide a kind of elevator emergency brake device.
The present invention adopts following technical scheme to realize: elevator emergency brake device, comprise the slipper being fixed on car four angles, cylindrical slideway is installed with in slipper, cylindrical slideway leads to top by shaft bottom, specifically brake strip is comprised in slipper, piston is connected with after brake strip, speed sensor and acceleration pick-up is also provided with in slipper, (it is front that car is provided with elevator door side to be provided with two row's adapter plates outside the car back side, another side on the other side is the back side), adapter plate leads to top by shaft bottom, the conductive plate being fixed on the car back side is provided with between two row's adapter plates, the relative permanent magnet of some groups of polarity is provided with inside two row's adapter plates, induction coil is provided with in conductive plate, car top is provided with primary controller, cage bottom is provided with Hydraulic Pump, Hydraulic Pump is connected to piston by hydraulic power line, primary controller is connected respectively to conductive plate, Hydraulic Pump, speed sensor and acceleration pick-up, wherein conductive plate is also connected with Hydraulic Pump.
Elevator still adopts bont and the control circuit of conventional lift, and normal start and stop control bont by control circuit and realize.Speed sensor, acceleration pick-up are monitored in real time to elevator, feedback data is to primary controller, when car speed and acceleration/accel are in alarm condition, primary controller hydraulic control pump startup piston promotes brake strip and compresses cylindrical slideway braking, adopt independent current source, still can normally work under powering-off state.If there is emergency situation even under powering-off state, elevator is once fall, and conductive plate induction coil cuts magnetic field that eternal magnet produces and produces electro-motive force, Direct driver hydraulic pump works, realizes braking elevator; And when powering normal, controlled by primary controller, conductive plate does not affect the normal start and stop of elevator.According to above-mentioned working process, primary controller control circuit and program thereof are that those skilled in the art easily realize.
Beneficial effect of the present invention is as follows: the present invention utilizes and sets up electromagnetism and hydraulic emergency braking device at lift car, achieves the braking of elevator under the emergency state.Structure of the present invention is simple, safe and effective, can not affect under the prerequisite that elevator normally runs, and realizes the in emergency circumstances elevator brake such as power-off.
