Abstract
The utility model relates to an elevator dragging rope force-bearing adjusting device. Oil cylinders and pistons are matched with each other and are penetrated at the middle of a rope head assembling device in turn, wherein, the upper ends of the oil cylinders are abutted below a crossbeam, the lower ends of the pistons are abutted with pad sheets, communicating pipelines which are communicate with each other are arranged at the upper side walls of a plurality of oil cylinders, and the oil cylinders are connected in parallel; thereby, the utility model has the advantages of reliable adjusting performance, easy installation and low cost.
Description
The utility model is the stressed hydraulic pressure automatic regulating apparatus of a kind of elevator rope.
At present, the lifting of lift car normally is suspended on the traction sheave by many hoist ropes, realizes by the rotating of traction sheave.In order to guarantee the safe operation of elevator, reduce the wearing and tearing of hoist ropes and traction sheave, require the stressed difference of each hoist ropes to be not more than 5%.For this reason, the terms of settlement that generally adopts is that field worker is regulated the length of fag end combiner by the nut of adjusting on the hoist ropes fag end combiner at present, thereby makes each hoist ropes stressed close.Yet owing to be subjected to the restriction of traction sheave working accuracy and the variation of hoist ropes tension, in fact adjusted hoist ropes is stressed will soon to change, cause the stressed difference of hoist ropes to be far longer than 5%, thereby influence the service life of hoist ropes, traction sheave and the safe operation of elevator.
The suspension gear of the hoist ropes of commonly using is normally formed (as shown in Figure 1) by fag end combiner 1, spring 3 and adjustment nut 4 and pad 5, and spring 3 upper ends are resisted against (elevator is connected on the crossbeam 2, and is not shown in the figures) on the crossbeam 2.
In view of this, the purpose of this utility model provides the stressed automatic regulating apparatus of a kind of elevator rope, and it is a ram pot of borrowing oil cylinder and piston to form, makes hoist ropes stressed equal.
The utility model purpose is achieved in that it comprises fag end combiner and lower end bonded assembly adjustment nut thereof, pad, and a crossbeam is passed in fag end combiner upper end, also wear oil cylinder and the piston that matches in the middle of the fag end combiner in regular turn, wherein the oil cylinder upper end is below crossbeam, piston lower end abutment pad, several oil cylinder upper side walls arranged side by side are provided with the connecting pipe that communicates with each other again.
Owing to adopt such scheme: adjust dependable performance, easy for installation, and cost is low.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 commonly uses the scheme drawing of setting device.
Fig. 2 the utility model exemplary embodiments scheme drawing.
Among the figure:
1, fag end combiner 2, crossbeam 3, spring 4, adjustment nut
5, pad 6, oil cylinder 7, piston 8, connecting pipe
Present embodiment mainly comprises fag end combiner 1, oil cylinder 6, piston 7, adjustment nut 4 and pad 5 compositions, as shown in Figure 2, and wherein:
Fag end combiner 1 connects the body of rod of hoist ropes (not shown) lower end, the bar of this fag end combiner 1 passes crossbeam 2, oil cylinder 6 and piston 7, until exposing piston 7 lower ends, and connect an adjustment nut 4 and pad 5, belong to prior art in the bar lower end of this fag end combiner 1.
The upper end of oil cylinder 6 is resisted against below the crossbeam 2, and each oil cylinder 6 upper side walls one hole can flow the liquid in each oil cylinder 6 with connecting pipe 8 connections mutually.
Piston 7 is with its outer wall and the mutual sliding fit of oil cylinder 6 inwalls, and these piston 7 lower end abutment pads 5, and available adjustment nut 4 bearings cap shim 5 are in the present position, bar lower end of fag end combiner 1.
The principle of work of this suspension gear is: as long as each hoist ropes exists stressed poor, stressed big hoist ropes to compress the piston 7 of ram pot by fag end combiner 1, piston 7 is contracted inward drive 1 elongation of fag end combiner, hoist ropes is stressed to diminish, fluid in the oil cylinder 6 is by entering stressed little oil cylinder 6 communicating pipe, make its piston 7 toward overhanging, driving fag end combiner 1 shortens, the stressed change of hoist ropes is big, stressed equal up to every hoist ropes, piston 7 motions of ram pot are corresponding stopping, thereby guarantee that stressed being in all the time of each hoist ropes dynamically equates situation.
The utility model has the advantages that cost is low, simple in structure, need not change former elevator suspension structure, and easy for installation, Dependable performance can effectively prevent the problem of hoist ropes unbalance stress.
