Abstract
The utility model discloses a novel promote device that safe and reliable is stable, it includes that wear ring, round pin axle, centrifugal pan, spring, brake lever and this six boards of centrifugation hammer divide the component. The one end at lifting means is installed to this kind of novel stopper, will sell the axle and insert the lifting means drive shaft and fixed by the both sides bolt. At equipment safe operation in -process, the centrifugation hammer is owing to the reason of spring force is concentric with the centrifugal pan, do not contact with the friction ring simultaneously, when lifting means loses the load suddenly, because the unexpected disappearance of load, lifting means's drive can not abrupt halt, lifting means will accelerate suddenly this moment, this moment is because the existence of centrifugal force, the effect of spring force can be overcome to the centrifugation hammer, centrifugal hammer will slow down to hoist mechanism with wear ring friction formation resistance this moment, make hoist mechanism slowly move in this frictional force, on -the -spot operating personnel can have the abundant time to stop the power supply.
Description
Technical field
The utility model proposes the brake of a kind of mechanical field, a kind of lifting device New Brake when losing suddenly load.
Background technology
Brake has been widely used in a mechanical field, is the requisite ingredient of mechanical movement.Brake operation on basic machine is the most stable, is related to the personal safety of operator, the fame of a plant equipment safety even enterprise and development prospect.Owing to using the brake on lifting device of a great variety on the market now; but can not effectively control accident development in the course of the work; the most suddenly load is lost; brake can not reliable and effective protection basic machine; associated mechanical body is caused to be destroyed; maintenance difficulty is big, and cost is high, also affects enterprise efficiency simultaneously.In order to solve these problems, therefore devise this Novel hoisting device brake.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing brake, it is provided that a kind of safe and reliable stable New Brake.This New Brake will play effective braking action when lifting device loses suddenly load, it is to avoid the generation of security incident, and ensure the safety of basic machine.
Be the technical scheme is that a kind of Novel hoisting device brake by realizing the purpose of this utility model, it is made up of this six part of wear ring, bearing pin, centrifugal pan, spring, brake bar and centrifugal hammer.This New Brake is arranged on one end of lifting means, bearing pin inserts lifting means drive shaft and is fixed by both sides bolt.During equipment safety operation, centrifugal hammer is concentric with centrifugal pan due to the reason of spring force, do not contact with drag ring simultaneously, when lifting means loses load suddenly, due to suddenly disappearing of load, the driving of lifting means can not stop suddenly, now lifting means will accelerate suddenly, now due to the existence of centrifugal force, centrifugal hammer can overcome the effect of spring force, now hoisting mechanism will be slowed down by centrifugal hammer with wear ring friction formation resistance, make hoisting mechanism in the slow action of this frictional force, on-the-spot operator can have the sufficient time to stop power source.
The beneficial effects of the utility model are: when lifting device loses load suddenly; centrifugal hammer can overcome the elastic force of spring to form resistance with wear ring friction under the influence of centrifugal force; within can effectively making lifting device drop to safe speed; on-the-spot staff has the time of abundance drive system to be turned off, protection personal safety and equipment safety.
Accompanying drawing explanation
Fig. 1 is the structure chart of Novel hoisting device brake；
1-bearing pin, 2-centrifugal hammer, 3-centrifugal pan, 4-brake bar, 5-wear ring, 6-spring in figure.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings: if Fig. 1 is Novel hoisting structure drawing of device, centrifugal hammer 2 bearing pin 1 is fixed on centrifugal pan 3, spring 6 one end is fixed on centrifugal pan, the other end is fixed on centrifugal hammer, one end of brake bar 4 is inserted the centrifugal pan other end and is inserted lifting means, and one end that wear ring 5 is arranged on hoisting mechanism in outermost is concentric with centrifugal pan 3.
During equipment safety operation, centrifugal hammer 2 is concentric with centrifugal pan 3 due to the reason of the spring force of spring 6, do not contact with wear ring 5 simultaneously, when lifting means loses load suddenly, due to suddenly disappearing of load, the driving of lifting means can not stop suddenly, now lifting means will accelerate suddenly, now due to the existence of centrifugal force, centrifugal hammer 2 can overcome the effect of the spring force of spring 6, and now hoisting mechanism will be slowed down by centrifugal hammer 2 with the wear ring 5 formation resistance that rub.
What this specification was enumerated is only better embodiment of the present utility model, all equivalent technologies done under operation principle of the present utility model and thinking and reconfiguration, is accordingly to be regarded as protection domain of the present utility model.
Claims (3)
1. a Novel hoisting device brake, it is characterised in that: include that bearing pin (1), described bearing pin (1) they are centers of rotation during centrifugal hammer (2) work, centrifugal hammer (2) played the effect of location simultaneously；Centrifugal hammer (2), described centrifugal hammer (2), when safe mode is run, is acted on by spring force, and now centrifugal hammer (2) is concentric with centrifugal pan (3)；When lifting device loses load suddenly, the centrifugal force suffered by centrifugal hammer (2) is more than the elastic force of spring (6), and now centrifugal hammer deviates to wear ring (5), contacts generation frictional resistance with wear ring (5) and makes lifting device be decelerated to safe operation speed；Wear ring (5), described wear ring (5) is under non-secure states, and centrifugal hammer (2) produces resistance with wear ring (5) friction；Centrifugal pan (3), described centrifugal pan, it plays fixed pin shaft (1), brake bar (4) and one end of spring (6)；Brake bar (4), described brake bar, it plays the effect being connected with lifting device；Spring (6), described spring (6), its one end is fixed on centrifugal hammer (2), and the other end is fixed on centrifugal pan (3), plays the effect of fixing centrifugal hammer (2) when safe operation.
A kind of Novel hoisting device brake the most according to claim 1, it is characterised in that: with the balancing weight of constant weight on described centrifugal hammer (2), in order to ensure that the centrifugal-block under duty can produce sufficiently large centrifugal force.
A kind of Novel hoisting device brake the most according to claim 1, it is characterised in that: described spring (6) has the selection of Multiple Type, it is adaptable to different workplaces.
