Abstract
The utility model relates to a speed control device in the mechanical field, in particular to a hoist speed limiter. To solve technical problems that in the prior art, the current structures are unreasonable and the brake methods are not applicable to the steel wire rope traction type cargo-passenger construction hoists, the utility model provides a steel wire rope traction type cargo-passenger construction hoist speed limiter having advantages of reasonable structure and brake method. The model includes an axis, a rotary disc suited on the axis and a friction disc fixed on the shell of the traction machine, friction plates arranged between the rotary disc and the friction disc.
Description
Technical field
The utility model relates to a kind of speed control unit of mechanical field, especially relates to a kind of elevator velocity limiter.
Background technology
At present, the dual-purpose building hoist of steel rope traction-type people goods of domestic use is low because of its cost, maintaining is convenient, comparing with other forms of building hoist has very big advantage, but because there is not suitable speed-limit device, its safety performance is not ensured, thereby the use of the dual-purpose building hoist of steel rope traction-type people's goods is very limited.As a kind of patent No. is the motor bike automatic speed-limiting glider of CN01256405.2, his structure comprises sprocket wheel, buffer body, cam cover, drive sleeve and end cap, sprocket wheel and cam cover are fixing, buffer body and drive sleeve are fixed, between cam cover and drive sleeve, has floating bushing, be evenly equipped with at least two curved surfaces on the inner periphery of cam cover with lift feature, between this curved surface and drive sleeve, has roller, this roller is arranged in the breach of floating bushing, the end of drive sleeve be equipped with can with the centrifugal friction clutch of floating bushing frictional engagement.Simple in structure, the reliability height, can realize the energy-conservation coasting speed that surmounts of automatic guidance.The structure of this motor bike automatic speed-limiting glider and brake mode are not suitable for the dual-purpose building hoist of steel rope traction-type people goods.
Summary of the invention
The utility model mainly is at the existing in prior technology unreasonable structure, brake mode is not suitable for being applied in the dual-purpose building hoist brand-name of steel rope traction-type people goods technical matters, provide a kind of rational in infrastructure, the dual-purpose building hoist velocity limiter of steel rope traction-type people goods of advantage such as brake mode is reasonable.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: axle, be enclosed within the rotating disk on the axle and be fixed on friction disc on the towing machine casing, between rotating disk and the friction disc friction lining is arranged; Friction lining can move between rotating disk and friction disc, can be adjacent to friction disc, also can separate with friction disc.
As preferably, there be centrifugal between described rotating disk and the friction lining, centrifugal both sides have through hole, have pin to pass through hole; Pin is used for connecting spring, makes the spring tension.
As preferably, described centrifugal has two soon, is symmetrically distributed in the both sides of rotating disk; Two centrifugal symmetrical distributions can improve its stability.
As preferably, described both ends of the spring is connected the pin head, and spring one has four, spring symmetrical distribution parallel to each other; Four springs are symmetrically distributed and can improve stability, are difficult for producing displacement when rotating.
As preferably, have a hole in the middle part of the described friction lining, a screw passes the hole and is connected with centrifugal; By screw friction lining is fixed on centrifugal.
As preferably, described rotating disk one end has flange, and the height of flange is 0.2 ~ 0.8 with the ratio of the height of rotating disk; This structure can saving in material, increases intensity.
As preferably, described centrifugal one side has back-up ring, and back-up ring is fixed on the friction disc, and the open end of friction disc and stifle form airtight cavity with screw attachment; Its structure can form a cavity, contains whole mechanisms, can play dustproof, the effect of protection.
As preferably, described friction lining is an asbestos brake lining; Select asbestos brake lining for use, because its low price, result of use is good.
As preferably, the end that described friction disc connects with stifle has groove, and stifle is fixed in the groove; Stifle plays the leak free effect, effectively prevents entering of dust foreign material.
Therefore, the utlity model has rational in infrastructurely, safe and reliable, long service life makes things convenient for characteristics such as installation and maintenance.
