Abstract
The utility model provides a speed governor, which comprises a spring, a friction pair assembly, a sealing bar, a brake block assembly and a centrifugal block, wherein a friction pair is connected with a gasket in a bonding way; after bonding, two ends of the friction pair are ground flush to form the friction pair assembly; two baffles are connected with a brake block to form the brake block assembly; the spring is connected with the friction pair assembly; the brake block assembly is connected with the centrifugal block by the sealing bar; the centrifugal block and the sealing bar are respectively connected with the brake block assembly to form a whole; the spring is connected with the brake block assembly; the friction pair assembly is fixed to the surface of the centrifugal block. After the adoption of the speed governor, the speed can be effectively controlled in a certain range, the expectant safe effect can be thus reached, and the speed governor has the advantages of simple structure, convenience in manufacturing and the like.
Description
Technical field
The utility model relates to a kind of mechanical field, particularly a kind of velocity limiter.
Background technology
In prior art, at present, aerial work basket braking is main by braking motor stop, thereby equipment is stopped, but in use, the phenomenon that exceeds the speed limit appears in equipment sometimes, motor is difficult to timely stop, thereby secure context reduces greatly, also be difficult to reach the desired location of oneself wanting arrival, in use, this has increased the safety performance that equipment uses difficulty and reduced equipment undoubtedly, so be badly in need of now both safety of one, simultaneously again can be by speed control velocity limiter within the specific limits.
Utility model content
The object of the utility model equipment is to overcome the deficiencies in the prior art, and both safety of one is provided, simultaneously again can be by speed control velocity limiter within the specific limits.
The utility model provides a kind of velocity limiter, comprising: spring, friction pair assembly, sealing band, scotch block assembly and centrifugal-block, and wherein, friction pair and liner link together by bonding way, and the two ends after bonding polish and have formed friction pair assembly; Between two baffle plates and slipper, link together, form scotch block assembly, described spring is connected with described friction pair assembly, scotch block assembly is connected with centrifugal-block by sealing band, centrifugal-block is connected respectively with in slipper group with sealing band, form an entirety, and connect scotch block assembly with spring, friction pair assembly is fixed on the surface of centrifugal-block.
The beneficial effects of the utility model: adopting after velocity limiter can be effectively by speed control within the specific limits, thus reach the safe effect of expection, and the utility model equipment has the advantages such as simple in structure, easily manufactured.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of velocity limiter of the present utility model;
Fig. 2 is the structural representation of a kind of friction pair assembly of the present utility model;
Fig. 3 is the structural representation of a kind of scotch block assembly of the present utility model.
In figure, 1, spring, 2, friction pair assembly, 3, sealing band, 4, scotch block assembly, 5, centrifugal-block, 6, liner, 7, friction pair, 8, baffle plate, 9, slipper, 10, baffle plate.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described, is to be noted that described embodiment is only intended to be convenient to the understanding of the present invention, and it is not played to any restriction effect.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Figure 1-3, the utility model provides a kind of velocity limiter, comprising: spring 1, friction pair assembly 2, sealing band 3, scotch block assembly 4 and centrifugal-block 5 form.Wherein, friction pair 6 links together by bonding way with liner 7, and the two ends after bonding polish and formed friction pair assembly 2.Centre between two baffle plates 8 and 10 arranges slipper 9, such two baffle plates 8 and 10, and link together between slipper 9, form scotch block assembly.Velocity limiter is take scotch block assembly as basis, and centrifugal-block 5 and sealing band 3 are arranged on respectively in slipper group 4, forms annexation, and connects scotch block assembly with spring, and back-moving spring, and friction pair assembly 2 is fixed on the surface of centrifugal-block 5.This velocity limiter is arranged between motor and retarder.Sealing band can be rubber.In the time of the overspeed of hanging basket equipment, velocity limiter is due to operating on centrifugal force, now operating on centrifugal force is greater than the pulling force of spring, centrifugal-block has overcome the resistance of spring, outward radial moves, until the friction pair assembly on centrifugal-block surface contacts with the friction shoe being arranged on retarder, thereby generation friction force, play the effect that reduces hanging basket device rate, until hanging basket device rate returns to normal condition, now, operating on centrifugal force is less than the pulling force of spring, centrifugal-block gets back to initial position, thereby reaches the effect of limited speed.
The technical scheme providing according to the utility model equipment, velocity limiter in described lift for high crading, is a kind of by speed control device within the specific limits.Can be effectively by speed control within the specific limits when the utility model equipment uses, the utility model equipment has the advantages such as simple in structure, easily manufactured.
Describing is above only a specific embodiment of the present invention, and obviously anyone modification of doing of this area or local replacement under technical scheme of the present invention instructs, all belong to the scope that the claims in the present invention book limits.
