Abstract
A double speed fast unrolled windlass mechanism belongs to the windlass mechanism. A sun wheel of the windlass mechanism is connected with a heavy load input shaft, the top of a planet bracket is connected with the input shaft of a light load; the heavy load input shaft and the light load input shaft are connected with the constant close coil type arrestor; or through the decelerator, the two shafts are connected with the constant close coil type arrestor. The planet bracket is rotatable, thus, the windlass has two free degrees. When adopting two motors and two coil type constant close coil type arrestors, the two motors work respectively, so two different rotary speeds are provided, the two motor can work at the same time, controlling and adjusting the rotary direction and revolution speed of the two motors can synthesize a required output revolution speed; when one motor and two constant coil type arrestors are adopted, the target of idle load fast unrolling can be realized. The windlass is skillful in design, unique in structure, which can roll the cable in low speed at heavy load, and can roll the cable in high speed at light load, and can unroll the cable at idle load, so as to utilize the original mechanism sufficiently, thereby the operation efficiency can be greatly improved.
Description
Technical field the utility model relates to a kind of hoisting mechanism, and particularly a kind of double speed unreels soon raises mechanism.
Background technology is present, that known hoisting mechanism has is planetary, fixed shaft type and dead axle planetary set are box-like, wherein planetary hoisting mechanism has a reel, internally toothed annulus is arranged in reel, internally toothed annulus is by satellite gear and sun wheel engaged transmission, and the sun wheel center is connected with a transmission shaft, and transmission shaft is connected with motor by drg, satellite gear is connected an end of pinion carrier, and the end face of the other end of pinion carrier is connected with the housing of normally closed plate disc brake, still; There is a hole at the center, and transmission shaft passes from the center, and pinion carrier is actionless, and transmission shaft is connected with the moving plate of normally closed plate disc brake, and the moving plate of normally closed plate disc brake is between the still of normally closed plate disc brake.Because the winch pinion carrier is a transfixion, so it has only one degree of freedom and a fixing speed ratio, itself can not be realized heavy-duty low-speed, underloading high speed, unloaded function of putting soon, and the primary mover capacity utilization ratio is low, influences operating efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of heavy-duty low-speed, underloading high speed, the unloaded double speed of putting soon to unreel soon and raise mechanism.
The sun wheel that the purpose of this utility model is achieved in that this winding plant is gone into axle with the heavy duty wheel and is connected, and the end of pinion carrier is connected with the underloading input shaft.
The heavy duty input shaft all is connected with normally closed plate disc brake with the underloading input shaft; Perhaps be connected with normally closed plate disc brake by retarder.
Beneficial effect: owing to adopt such scheme, pinion carrier is rotating, so hoisting mechanism has two degree of freedom.When adopting the normally closed plate disc brake of two motors and two disc types, two motors are worked respectively, two different rotating speeds are promptly arranged, two motors are worked simultaneously, control, adjust the turning to of two motors, rotating speed can synthesize a needed output speed, has realized heavy-duty low-speed, the high-revolving purpose of underloading; When adopting the normally closed plate disc brake of a motor and two, the normally closed plate disc brake of control underloading can be realized unloaded purpose of putting soon, has reached the purpose of this utility model.This hoisting mechanism is skillfully constructed, the structure uniqueness, can be when heavy duty high speed serving when low speed serving, underloading, put rope fast when unloaded, made full use of primary mover, improved operating efficiency greatly.
Description of drawings
Fig. 1 is the constructional drawing of the utility model first embodiment.Fig. 2 is the constructional drawing of the utility model second embodiment.
The specific embodiment
Embodiment 1: this hoisting mechanism has a reel 2, internally toothed annulus 3 is arranged in reel 2, internally toothed annulus 3 is by satellite gear 4 and sun wheel 5 engaged transmission, sun wheel 5 centers are connected with a heavily loaded input shaft 8, heavy duty input shaft 8 is connected with normally closed plate disc brake 1, satellite gear 4 is installed on the pinion carrier 6, and the other end of pinion carrier 6 is connected with normally closed plate disc brake 1 by light-duty axle 9.
Embodiment 2: heavily loaded input shaft 8 is connected with normally closed plate disc brake 1 by two-stage reduction gear 10, and underloading input shaft 9 is connected with normally closed plate disc brake 1 by one-level retarder 11, and other and embodiment 1 omit together.
Claims (2)
1, a kind of double speed unreels soon and raises mechanism, it is characterized in that: the sun wheel of this winding plant is gone into axle with the heavy duty wheel and is connected, and the end of pinion carrier is connected with the underloading input shaft.
2, double speed according to claim 1 unreels soon and raises mechanism, it is characterized in that: heavily loaded input shaft all is connected with normally closed plate disc brake with the underloading input shaft; Perhaps be connected with normally closed plate disc brake by retarder.
