Abstract
The utility model provides an automatic tensioning compensation device for the extension of a steel rope of a traction elevator, which can compensate for the linear extension of the steel rope automatically, promptly and continuously, and does not needs inspection or operational adjustment at intervals so as to reduce the amount of inspection and operation during onsite maintenance. The automatic tensioning compensation device comprises a lever system, and the lever system comprises a support seat, a lever supported on the support seat in a rotating way and a counterweight connected with one end of the lever; and the steel rope passes through the other end of the lever and can be tensioned under the effect of the counterweight.
Description
Technical field
The utility model relates to a kind of traction elevator rope stretch automatic tension compensating device, it is applicable to traction elevator, particularly indirect-drive towed formula elevator, in, owing to, steel rope need be designed to the occasion of a force-closed system from the technical design angle.
Technical background
In traction elevator, in the particularly indirect-drive towed formula elevator, owing to, steel rope need be designed to the occasion of a force-closed system from the technical design angle.The tension force of steel rope is to guarantee between towing machine traction sheave and steel rope enough friction force are arranged, and produces driving torque, overcomes overbalance torque maximum between lift car and the counterweight to satisfy.And this drive system steel rope is designed to a force-closed system, and along with elevator ceaselessly is used operation, steel rope can linear elongation.According to design and engineering practice in the past, behind the rope stretch, need in maintenance process, the fag end spring of steel rope be tightened or the brachymemma steel rope solves by elevator service personnel, field maintemance inspection and working out strengthen.
The utility model content
The purpose of this utility model provides a kind ofly can carry out automatically in time Continuous Compensation to steel rope linear extension, and need not to go cross-check sum operation adjustment at interval the rope stretch auto-tensioning compensating device that is used for traction elevator of cross-check sum working out when alleviating on site maintenance every certain maintenance activity.
The rope stretch auto-tensioning compensating device that is used for traction elevator of the present utility model comprises lever on bearing of bearing, rotational support, is connected the lever system that the counterweight of lever one end is formed; Steel rope is by the other end of lever, and under the effect of counterweight, steel rope is tensioned.
The beneficial effects of the utility model: the utility model is by the counterweight of lever one end, the feasible lever other end by steel rope is in all the time by the state of perk, thereby to the steel rope in tension, promptly satisfied the requirement of elevator device, simultaneously the linear extension of steel rope has been compensated in good time tension force.This auto-tensioning compensating device makes the timely Continuous Compensation of steel rope linear extension, cross-check sum working out when once solving on site maintenance to a large extent, rather than adjust with the cross-check sum operation of certain maintenance activity pitch time.
Above-mentioned rope stretch auto-tensioning compensating device, the arm of force of counterweight one end of lever is greater than the arm of force of the other end.By the lever ratio of this lever system, hang with the counterweight of lower weight and to amplify suitable suspended weights, make the steel rope in tension.
Above-mentioned rope stretch auto-tensioning compensating device, the other end of lever is near near the fixed end of steel rope.
Above-mentioned rope stretch auto-tensioning compensating device, lever system is positioned at the top or the bottom of the elevator hoistways of traction elevator.
Above-mentioned rope stretch auto-tensioning compensating device, lever system are positioned at car one side or counterweight one side of traction elevator.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
Referring to rope stretch auto-tensioning compensating device shown in Figure 1, comprise lever 2 on bearing of bearing 1, rotational support, be connected the lever left end counterweight 3, the lever system that the fixed pulley 4 of lever right-hand member is formed is set; Steel rope 5 in the steel rope system 6 is walked around fixed pulley 4.Under the effect of counterweight 3, steel rope 5 is tensioned.The arm of force (the lever left end is to the distance of bearing) of counterweight one end of lever is greater than the arm of force (the lever right-hand member is to the distance of bearing) of the other end.
The utility model amplifies with less counterweight (weight suspension) 3, satisfies the elongation of steel rope 5 in steel rope system 6 due tension force tensionings and the automatic compensation steel rope system, and does not need just to go at regular intervals maintenance examination or brachymemma steel rope.
Two ends at steel rope system, wherein an end is fixed, and the other end is designed to a lever system, lever ratio by this lever system, hang the suitable suspended weights of amplification with less weight, make the steel rope in tension, promptly satisfied the requirement of elevator device, simultaneously the linear extension of steel rope is compensated in good time tension force.This auto-tensioning compensating device, cross-check sum working out when once solving on site maintenance to a large extent.Thereby make the timely Continuous Compensation of steel rope linear extension, rather than adjust with the cross-check sum operation of certain maintenance activity pitch time.
