Abstract
The utility model discloses a diversion sheave damping device for an elevator car roof. The diversion sheave damping device comprises a diversion sheave, a diversion sheave support and a fixing plate. The diversion sheave support on the upper portion and the fixing plate on the lower portion are arranged in parallel, three elastic damping elements are arranged between the diversion sheave support and the fixing plate in three rows respectively in an abreast mode. A bolt penetrating through the middle elastic damping element to tightly press the three elastic damping elements between the fixing plate and the diversion sheave support is fixedly connected between the fixing plate and the diversion sheave support. The diversion sheave damping device has the advantages that a good damping effect can be achieved, and the diversion sheave damping device is compact in structure and easy to maintain.
Description
Technical field
The utility model relates to a kind of elevator components, is specifically related to a kind of elevator car top diversion sheave shock absorption device.
Background technology
Elevator diversion sheave device is a kind of movable pulley being applied on elevator, is conventionally arranged on the movable pulley of car frame and counterweight framework upper.Hoist ropes is walked around diversion sheave and can be formed different traction ratios as required, and its effect is to reduce the horsepower output of towing machine and moment.Traditional elevator car top diversion sheave adopts rubber damping technology, by the rubber on both sides, be arranged on symmetrically on two side shafts of rope sheave, rubber has been used of a specified duration can be aging, after long-term use, elasticity reduces, cushioning performance reduces, and under heavy duty, having larger creep, particularly sightseeing elevator, summer is in the glass hoistway of high temperature; It is exactly that oil resistance is poor that rubber also has a problem.
Before this, Chinese patent CN03236134.3 discloses a kind of vibration damper for high-speed elevator cage, it is connected elastic damping element between anti-rope device and car crossbeam, wherein anti-rope device is comprised of diversion sheave axle, antifriction-bearing box, diversion sheave, steel rope and diversion sheave support, its elastic damping element symmetry is distributed in car gravity vertical surrounding, two diversion sheave supports are fixedly connected with diversion sheave axle two ends respectively, its diversion sheave support is parallel corresponding with car crossbeam, fixes elastic damping element between the two.The bearing of diversion sheave is the antifriction-bearing box that has the play gap of 0.5-1.0mm, and the material of diversion sheave is nodular cast iron, can not produce because diversion sheave loses circle and produce vibration.Elastic damping element is elastic damping rubber pad or elastic damping spring.This device advantage is reasonably to arrange and select damping element, and shock pad distributes rationally, and the gravity vertical of car is in elastic damping pad center, stable, has solved the skew of gravity vertical left and right and produces the problem of rocking and vibrating.But in practical application, its structure is comparatively complicated, and manufacturing cost is high, is not easy to large-scale promotion application, and its practicality also needs to be improved.
Utility model content
The utility model object is to overcome above-mentioned deficiency, and a kind of elevator car top diversion sheave shock absorption device is provided, and it not only can play good damping effect, and compact conformation, is easy to safeguard.
The utility model is achieved through the following technical solutions utility model object: a kind of elevator car top diversion sheave shock absorption device, comprise diversion sheave, diversion sheave support, adapter plate, described diversion sheave support is upper and lower parallel placement with adapter plate, be provided with three elastic shock attenuation elements that are single-row concordant placement therebetween, between described adapter plate and described diversion sheave support, be fixedly connected with one and penetrate in elastic shock attenuation element placed in the middle so that these three elastic shock attenuation elements are pressed on to the bolt between adapter plate and diversion sheave support.
Further, described elastic shock attenuation element is spring.
Further, described bolt is hexagonal bar iron.
Further, described diversion sheave support is parallel corresponding with car crossbeam.
Compared with prior art, the utlity model has following good effect: reasonably arrange and select elastic shock attenuation element, elastic shock attenuation element distributes rationally, and the gravity vertical of car hits exactly in three elastic shock attenuation elements, and quite stable is in operation.Three elastic shock attenuation elements are to single-row concordant arrangement, and compact conformation, be easy to safeguard.
Accompanying drawing explanation
Figure is structural representation of the present utility model.Wherein, 1 is adapter plate, and 2 is diversion sheave support, and 3 is spring, and 4 is bolt.
The specific embodiment
Below with reference to the accompanying drawings shown in, in conjunction with example, the utility model is described further.
As shown in Figure 1, a kind of elevator car top diversion sheave shock absorption device, comprise diversion sheave, diversion sheave support, adapter plate, described diversion sheave support is upper and lower parallel placement with adapter plate, be provided with three springs that are single-row concordant placement therebetween, between described adapter plate and described diversion sheave support, be fixedly connected with one and penetrate in spring placed in the middle so that these three springs are pressed on to the hexagonal bar iron between adapter plate and diversion sheave support, described diversion sheave support is parallel corresponding with car crossbeam.The improvement that the utility model carries out mainly for counterweightless direct-drive type home lift, the foregoing is only the utility model preferred embodiment, non-ly therefore limit to the scope of the claims of the present utility model, therefore simple and easy variation and the equivalent transformation of such as doing by the utility model specification sheets and graphic content, all should be contained in the scope of the claims of the present utility model.
Claims (4)
1. an elevator car top diversion sheave shock absorption device, comprise diversion sheave, diversion sheave support, adapter plate, it is characterized in that: described diversion sheave support is upper and lower parallel placement with adapter plate, be provided with three elastic shock attenuation elements that are single-row concordant placement therebetween, between described adapter plate and described diversion sheave support, be fixedly connected with one and penetrate in elastic shock attenuation element placed in the middle so that these three elastic shock attenuation elements are pressed on to the bolt between adapter plate and diversion sheave support.
2. a kind of elevator car top diversion sheave shock absorption device according to claim 1, is characterized in that described elastic shock attenuation element is spring.
