Abstract
The invention relates to a vertical elevator falling rescue device adopting buoyancy technology, which comprises a car bottom reduction unit, reduction liquid, a reduction arresting cable, a pressure relief opening and a liquid control replenishing device. By the aid of the vertical elevator falling rescue device, the shortcomings of an existing mechanical reduction unit and an electrical reduction unit can be effectively overcome, maintenance is omitted, a car is decelerated under the combined action of the reduction liquid and the reduction arresting cable to realize soft landing, and life safety of passengers is guaranteed. The vertical elevator falling rescue device is applicable to falling of vertical elevators of high-rise, mid-rise and low-rise buildings, and is high in safety coefficient so that the life of the passengers can be protected at the utmost.
Description
Technical field
The present invention relates to the elevator technology field, the car that relates in particular in a kind of vertical-type elevator relies on the liquid buoyancy speed reduction gearing to save the technology of passenger's life when the high-altitude accidental falling takes place, and belongs to the device security technical field.
Background technology
Elevator is the transportation device of vertical direction in the skyscraper, generally is made up of hoistway and machine room, running part, up-down 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 driving engine and steel rope, generally is installed in the top of machine room, and it is through 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, and velocity limiter is the equipment of control car speed, when car reaches capacity speed; The car velocity limiter begins action, and acts on and force it to clamp guide rail on the safety tongs, checks car; Energy disperser is the last safety guard-safeguard of elevator, and it is installed in the elevator hoistways pit, be positioned at car and counterweight under; In elevator moved up or down, because wire cable rupture, brake sticking brake power was not enough or control system is malfunctioning and when making car surmount the terminal stop; Energy disperser plays buffer action, avoids elevator to hit the end.The working process of elevator is to drag steel rope through 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 used during elevator falling 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 at present mainly is at fixing several groups of springs of elevator hoistways pit or hydraulic ram; When used during elevator falling; Antagonistic force through spring or hydraulic ram plays buffer action, sort buffer power weak effect, and resonance effect appears easily.
Summary of the invention
The object of the present invention is to provide a kind of buffer protection device used during elevator falling that relies on the buoyancy technology.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is:
A kind of buffer protection device used during elevator falling; Comprise car, car bottom shock absorber, be arranged at the deceleration liquid in the elevator hoistways pit; The cross check cable that is connected to pressure relief opening is arranged in the deceleration liquid, it is characterized in that: described car bottom shock absorber and the combined action of deceleration liquid realize deceleration of elevator.
Car of the present invention bottom shock absorber is the inflatable bag that is arranged at bottom outside, and it links to each other with automatic device measuring.
There is deceleration liquid in liquid deceleration of the present invention pond for being arranged at square pond in the elevator hoistways pit in it, the deceleration pond is connected in the liquid device for supplying.
Cross check cable of the present invention is connected in pressure relief opening.Multiple cross check cable plays multiple deceleration effort, and each check cable links to each other with pressure relief opening, in case elevator falls to check cable, check cable is opened pressure relief opening, and check cable not only plays deceleration effort but also can discharge liquid protection passenger.
Description of drawings
Accompanying drawing is the scheme drawing of buffer protection device used during elevator falling of the present invention.
Among the figure: 1-leg, 2-floor plates, 3-car, 4-automatic device measuring, 5-car bottom shock absorber, 6-liquid device for supplying, 7-deceleration liquid, 8-pressure relief opening, 9-cross check cable, 10-pressure release pond.
The specific embodiment
At first automatic device measuring (4) is measured cage operation speed when elevator moves, automatic device measuring according to degree of testing the speed decision whether start other devices, start like need, car bottom shock absorber (5) is inflated rank according to decision highly.
Then car bottom shock absorber (5) is realized slowing down with deceleration liquid (7) mutual action; Realize once more slowing down when falling certain depth car and cross check cable (9) mutual action; Cross check cable (9) is opened pressure relief opening (8) and is avoided the passenger to suffocate, and deceleration liquid (7) flows into pressure release pond (10) via pressure relief opening (8).Behind said process, when car arrives the hoistway bottom, pull off a soft landing, thereby reach the purpose of protecting passenger's life.
Claims (5)
1. failure-free used during elevator falling shock absorber is characterized in that: it is the vertical-type used during elevator falling rescue device that adopts liquid buoyancy, cross check cable buffer technology.
2. a kind of failure-free used during elevator falling shock absorber according to claim 1; Comprise car, be arranged at the cross check cable, the car bottom shock absorber that are connected to pressure relief opening in the liquid deceleration pond, liquid deceleration pond of elevator bottom, it is characterized in that: car is in the liquid combined action realization deceleration down with mechanical reduction of slowing down.
3. a kind of failure-free used during elevator falling shock absorber according to claim 1; It is characterized in that: when elevator is out of control; Automatic device measuring starts, and inflates to the device that the car bottom increases buoyancy according to the survey data, and the shock absorber of car bottom starts corresponding buffering rank according to the survey data.
4. a kind of failure-free used during elevator falling shock absorber according to claim 1 is characterized in that: possess deceleration liquid in the pit of elevator, it is by the control of liquid device for supplying, and the shock absorber effect of deceleration liquid and car bottom reaches the purpose of deceleration.
5. a kind of failure-free used during elevator falling shock absorber according to claim 1, it is characterized in that: the cross check cable in the liquid links to each other with pressure relief opening, and pressure relief opening is opened in check cable and the effect of car bottom, and pressure relief opening plays the effect of protection passenger life.
