Abstract
The utility model discloses an elevator falling amortization and protection device, comprising an elevator car and a mechanical shock damper fixed in elevator shaft, wherein the medium of the top frame of the elevator car is connected with a trolley seat, the pulley rotarily connected on the trolley seat, the external side at the bottom of the elevator car has electric magnet with same pole with that on the bottom of the shaft, and the electric magnet is connected with power supply by a microswitch. The trolley seat and the top frame of the car can be a slight moving structure up and down, a group of microswitches are installed between the trolley seat and the frame, for switching on when the trolley seat moves downwards. Once the wire rope is fractured, the trolley seat moves downwards by gravity force and spring force, thereby switching on the microswitches that is simultaneously switching on electric magnet power supply, then the electric magnet generates a electromagnetic force, because the electric magnets fixed at external side of the bottom of the car and the elevator shaft is homopolar opposite electric magnet, the repulsion force provides amortization and damping for the car, and quickly makes the car holding stationary.
Description
Technical field
The utility model relates to the elevator technology field, buffering, shock-absorbing protecting device when relating in particular to a kind of used during elevator falling.
Background technology
Elevator is the transportation device of vertical direction in the skyscraper, generally is made up of hoistway and machine room, running part, lifting part, control part, safety device five parts; Hoistway surrounds a finite space that holds lift car and counterweight by leg, top board and pit, has entry and exit at each stop; Machine room is arranged on the top of hoistway, is used for installing towing machine, automatically controlled screen, velocity limiter etc., and pit generally gos deep into ground, is used to install energy disperser, velocity limiter, steel wire rope stretching device; Running part is a towing machine, mainly is made up of electrical motor and steel rope, generally is installed in the top of machine room, and it is by rope traction car and counterweight; Jacking equipment partly comprises car, counterweight and guide rail; Safety device is made up of velocity limiter and energy disperser; velocity limiter is the equipment of control car speed; when car reaches capacity speed; the car velocity limiter begins action; and act on and force it to clamp guide rail on the safety tongs; check car; energy disperser is the last safety guard-safeguard of elevator; it is installed in the elevator hoistways pit; be positioned at car and counterweight under, in elevator moves up or down, because wire cable rupture; brake sticking brake power deficiency or control system are malfunctioning and when making car surmount the terminal stop; energy disperser then plays buffer action, avoids elevator to hit the end or rushes to summit.The working process of elevator is to drag steel rope by the motor drives towing machine car of elevator is moved up and down along the guide rail on the lift shaft enclosure, the frame mid portion of car top is equipped with pulley base and pulley, because steel rope is walked around this pulley and is stood flexural deformation for a long time, if steel rope ruptures when bending, will cause weighing down ladder and cause major accident, and fixedly fag end gets loose and unforeseen circumstances such as brake sticking brake inefficacy also this type of falling accident can take place when occurring.The elevator hoistways pit generally all is provided with buffer protection device for this reason; the fender guard that uses mainly is at fixing several groups of springs of elevator hoistways pit or hydraulic ram at present; when used during elevator falling; antagonistic force by spring or hydraulic ram plays buffer action; sort buffer power weak effect, and resonance effect appears easily.
Summary of the invention
The purpose of this utility model is to provide a kind of electromagnetic type buffer protection device used during elevator falling.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of buffer protection device used during elevator falling; comprise car, be arranged at the mechanical damper of elevator hoistways pit; the frame mid portion of car top is connected with pulley base; pulley is rotationally connected with on the pulley base, it is characterized in that: also be provided with the electromagnetic type bumper between described car bottom and the elevator hoistways pit.
Electromagnetic type bumper described in the utility model is to be arranged at the car bottom outside electromagnet relative with the homopolarity of elevator hoistways pit, and electromagnet is connected by micro-switch with power supply.
The framework of pulley base described in the utility model and car top flexibly connects, and described micro-switch is arranged between pulley base and the framework.The framework of pulley base and car top can be made the structure that can move on a small quantity up and down like this, and one group of micro-switch is installed between pulley base and the framework, makes its energy energized when pulley base moves down.In case like this behind the wire cable rupture, pulley base leans on gravity or spring force to bottom offset, thereby connect micro-switch and promptly connect electromagnet power supply simultaneously, at this moment electromagnet gets electric generation electromagnetic force, because being arranged at the car bottom outside is the relative electromagnet of homopolarity with the electromagnet of elevator hoistways pit, its repulsive force to the car that falls cushion, damping, and make the car held stationary very soon.
Mechanical damper described in the utility model is spring or the hydraulic ram that is arranged at the elevator hoistways pit, is known structure, is meeting power failure, still can play buffer protection function to the end when electromagnet can not play a protective role.

Accompanying drawing is the scheme drawing of the utility model buffer protection device used during elevator falling.
Among the figure: 1-framework, 2-micro-switch, 3-pulley, 4-hoistway, 5-car, 6-pulley base, 7-electromagnet, 8-well pit, 9-hydraulic ram.
The specific embodiment
Accompanying drawing is the scheme drawing of a kind of specific embodiment of the utility model buffer protection device used during elevator falling; framework 1 middle part at car 5 tops is connected with pulley base 6; pulley 3 is rotationally connected with on the pulley base 6; car 5 bottom outside are provided with the relative electromagnet of homopolarity 7 with the bottom surface of elevator hoistways pit 8, and electromagnet 7 is connected by micro-switch 2 with power supply.Pulley base 6 flexibly connects with the framework 1 at car 5 tops, and micro-switch 2 is arranged on the framework 1, and the side edge of its contact and pulley base 6 is touched.The bottom surface of elevator hoistways pit 8 is provided with hydraulic ram 9.
Claims (4)
1, a kind of buffer protection device used during elevator falling; comprise car, be arranged at the mechanical damper of elevator hoistways pit; the frame mid portion of car top is connected with pulley base; pulley is rotationally connected with on the pulley base, it is characterized in that: also be provided with the electromagnetic type bumper between described car bottom and the elevator hoistways pit.
2, buffer protection device used during elevator falling according to claim 1 is characterized in that: described electromagnetic type bumper is to be arranged at the car bottom outside electromagnet relative with the homopolarity of elevator hoistways pit, and electromagnet is connected by micro-switch with power supply.
