Abstract
The utility model relates to a high-efficient safe high-speed hoister, comprising a speed regulating screw, a movable and a fixed friction disks, springs, a fly hammer, a friction belt, a speed reducing box, a hydraulic brake, a motor, a shaft coupling joint, a drum, a bearing seat, a cooling water tank and a centrifugal friction starter. The centrifugal friction starter is composed of a driving wheel, a friction belt, a friction palm, a friction palm bracket, a friction palm mandrel, a tension spring, etc. Due to the cooling water tank which is arranged between the movable and fixed friction disks, the utility model can obtain the purpose that long-term braking can not result in overheating, and has good cooling effect; simultaneously, the centrifugal friction starter is improved, so that mechanical links and components are reduced, and accordingly, the purposes of safety, electricity saving, durability, low failure rate and easy maintenance can be obtained.
Description
The utility model relates to a kind of winch, particularly a kind of highly effective and safe high speed winch.
Number of patent application is in 94244226.1 the patent application, a kind of " highly effective and safe high speed winch " described, centrifugal friction drg wherein adopts the air cooling form, can cause the phenomenon of brake overheating when the downslide braking time is long slightly, and can influences the life-span of brake rubber block and bearing; In the centrifugal friction actuator, used part is more in addition, the mechanical link complexity, so durable inadequately, fault is more.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of good cooling results is provided, and the long period braking can be not overheated, and simple and reasonable, the highly effective and safe high speed winch of safety durable.
The purpose of this utility model can reach by following measure: the utility model comprises speed governing screw, movable friction disc, spring, flyball, friction skin, fixed friction dish, drop-gear box, hydraulic brake, electrical motor, shaft coupling, reel, bearing seat, it is characterized in that; Also has coolant storage tank, the centrifugal friction actuator of forming by friction drive wheel, friction skin, the friction palm, friction ramus volaris profundus frame, friction centre of the palm axle, tension spring, coolant storage tank is clamped between movable friction disc and the fixed friction dish, an end of two friction palms is loaded on the friction ramus volaris profundus frame by friction centre of the palm axle respectively in the centrifugal friction actuator, and the other end joins by tension spring and support.
Fig. 1 is a structural principle scheme drawing of the present utility model;
Fig. 2 is that A-A of the present utility model is to sectional structure chart;
Fig. 3 is that the utility model B is to view.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1～Fig. 3, the utility model is by speed governing screw 1, movable friction disc 2, spring 3, flyball 4, friction skin 5, coolant storage tank 6, fixed friction dish 7, drop-gear box 8, hydraulic brake 9, electrical motor 14, shaft coupling 17, reel 18, bearing seat 19, and the centrifugal friction actuator of being made up of friction drive wheel 10, friction skin 11, the friction palm 12, friction ramus volaris profundus frame 13, friction centre of the palm axle 15, tension spring 16.
An end of two friction palms 12 is loaded on the friction bracket 13 by friction centre of the palm axle 15 activities respectively in the centrifugal friction actuator, between the other end and the support 13 tension spring 16 is housed respectively.When not rotating, the friction palm 12 entad shrinks because of the effect of spring 16, and the friction palm 12 breaks away from friction drive wheel 10.After electrical motor 14 starts, drive support 13, the friction palm 12 rotation simultaneously, under action of centrifugal force, the friction palm 12 is that friction drive wheel 10 inwalls are pressed in the center rotation with axle 15, rotates simultaneously thereby drive power wheel 10, reaches the purpose of transmission.When electrical motor 14 stopped operating, the spring 16 drawing frictions palm 12 was replied and is shunk, and the friction palm 12 release the drives wheel 10 reaches the purpose of separation.Can not drive electrical motor 14 counter-rotatings during the power wheel high speed reverse rotation, the protection electrical motor is not damaged.
The utility model has following advantage compared to existing technology:
1, can reach the not overheated purpose of long period braking, good cooling results, and safety can Lean on, it is durable to economize on electricity.
2, simple and reasonable, reduced mechanical link and part, fault is few, easy-maintaining.
