Abstract
A drop buffer of elevator has a piston in hydraulic cylinder. A liquid tank is above the hydraulic cylinder with pipeline under it. Said pipeline is divided via three-way into parallel upper and lower pipelines. Lower pipeline with flow controller is connected to lower part of hydraulic box. Upper pipeline is directly connected to upper part of liquid storage box. The top of piston is fixed to drive mechanism connected via cable to cage.
Description
The present invention relates to a kind of drop buffer of elevator.
Many places use elevators in commercial production and life, the elevator in the high buildings and large mansions for example, and the cage in the mine, their are given work and give birth to draw together and brought very big convenience; Because the development of society, the facility that people carry out amusement and exercise health is also increasing, for example: aerial landing motion, at first climb up certain altitude and fall again, have certain interest, pungency; But when dropping near ground, because speed is too fast, used shock absorber buffering effect by spring or elastomeric material manufacturing is not ideal enough, causes fatal accident easily.Also can produce same problem when the wire cable rupture of elevator and cage or control mechanism are malfunctioning.
The objective of the invention is to design a kind of drop buffer that comprises the elevator of hydraulic actuating cylinder, liquid reserve tank, piston, flow-controlling gate and transmission device for overcoming above-mentioned weak point.When the elevator Control Failure, can obtain efficient buffer and protection when falling at a high speed.
The objective of the invention is to be achieved through the following technical solutions: this shock absorber is made up of main part such as liquid reserve tank, hydraulic actuating cylinder, piston, flow-controlling gate, transmission device, pulley mechanism; Piston is loaded in the hydraulic actuating cylinder, liquid reserve tank is established on hydraulic actuating cylinder top, cylinder lower is established pipeline, this pipeline is divided into two hydraulic tubings of upper and lower parallel connection through tee connection, be provided with flow-controlling gate in the following hydraulic tubing, this hydraulic tubing is connected with the hydraulic fluid tank bottom through flow-controlling gate again, and the hydraulic tubing of top directly is connected with liquid reserve tank; The downslide wheels of pulley drive mechanism are being fixed in the upper end of piston, and the top sheave group stationkeeping of pulley drive mechanism is on support, and the fixed pulley of rope through being fixed on the elevator platform of being drawn by pulley speed reducing mechanism is fixed on the cage of elevator then.
The reduction gearing mechanism of the shock absorber of elevator also can adopt three coaxial winch drums to form, and wherein the diameter of cylinder at two ends is little and captive joint with the piston upper end, and middle diameter of cylinder is big, and rope wherein is fixed on the cage of elevator through fixed pulley.
The transmission device of the drop buffer of elevator also can adopt finishing bevel gear cuter, screw-nut body, the bevel gear rear portion of both sides respectively is provided with and cage bonded assembly cylinder and the cylinder that resets, middle bevel gear is connected with leading screw, and slide plate fixing on the leading screw can move up and down in piston.
Advantage of the present invention: the elevator drop buffer utilizes degree of vacuum that elevator is dropped to bottom reposefully when elevator is out of control, can not damage machine, safety.
Description of drawings:
Fig. 1 is the drop buffer scheme drawing of elevator.
Fig. 2 is three transmission device scheme drawings that coaxial winch drum is formed.
Fig. 3 is bevel gear, feed screw nut transmission device scheme drawing.
Further specify the present invention below in conjunction with drawings and Examples, see also Fig. 1, hydraulic damping device is made up of main part such as liquid reserve tank 2, hydraulic actuating cylinder 1, piston 3, flow-controlling gate 8, transmission device, fixed pulley mechanism 6; The downslide wheels 4 of pulley (deceleration) transmission device are being fixed in the upper end that is loaded on the piston 3 in the hydraulic actuating cylinder, the top sheave group 5 of pulley (deceleration) driving device is fixed on the support, the rope of being drawn by the top sheave group is fixed on the cage 7 by two fixed pulleys, the height of cage lifter lifting is converted into a corresponding less piston adjustable height by (deceleration) driving device, for example, the reduction of speed ratio of pulley drive mechanism is 1: 20, so for high building with 10 layers, the stroke of piston in hydraulic actuating cylinder is slightly larger than 10/20, and promptly the height of 1/2nd first floor gets final product.The pipeline of cylinder lower should have certain altitude H, this pipeline can divide two-way up and down with being connected by tee connection 11 of hydraulic fluid tank, be connected with flow-controlling gate 8 in the following pipeline 10, the flow of this control cock can be regulated as required, the pipeline 9 of top directly is connected with liquid reserve tank, when elevator et out of order get out of hand, the cage of elevator descends rapidly, drive piston again by rope and pulley drive mechanism and rise, the liquid in the liquid reserve tank flows into cylinder lower by the pipeline of top simultaneously; When elevator drops to certain altitude, for example, when elevator is reduced to two floors, electrolyte level in the liquid reserve tank is lower than top pipeline, have only following pipeline to communicate between liquid reserve tank and the pressure cylinder, at this moment produce vacuum between piston and cylinder body, because the suction of vacuum stops piston to rise, the whereabouts that also stops elevator, be that liquid in the liquid reserve tank flows into hydraulic actuating cylinder by flow-controlling gate with less flow, piston is risen slowly, slow down, play the buffer action of elevator stable landing so the falling speed of elevator is also corresponding.The drop buffer of elevator can be located on the top of building or on the ground of mine, this shock absorber has increased by a heavy failure-free safety guard-safeguard concerning elevator.When elevator hoisted, pulley drive mechanism and position of piston resetted under the weight effect of piston.
Driving device also can be made up of three coaxial winch drums, sees also Fig. 2, and the two ends of this device are doffer 12,14, and the rope of doffer is received on the pulley 15 on piston top, and the centre is a swift 13, and the rope on the swift is connected on the cage of elevator;
Driving device also can adopt bevel gear, screw-nut body, please referring to Fig. 3, the bevel gear 18,19 that is positioned at both sides is equipped with rope on 17,20, two cylinders of cylinder respectively around on the contrary, and links on the cage of elevator, be provided with screw in the bevel gear 25 of bottom, leading screw 23 is housed in the screw, and slide block 24 is being fixed in the leading screw bottom, and slide block can be upper and lower mobile in piston, when moving to piston head, drive on the piston and moved buffer action.The outside of cylinder 17,20 is respectively equipped with return cylinder 16,21, and the rope lower end on it respectively is connected with weight 22, and when cage rose, this driving device automatically reset under the effect of weight.
