Abstract
The utility model relates to a novel intelligent multi-stage brake windlass which comprises a base frame, a winding drum, a speed reducer, an electromotor, a first-stage brake and an electric control box, the winding drum, the speed reducer, the electromotor, the first-stage brake and the electric control box are mounted on the base frame, an input shaft of the speed reducer is connected with the electromotor, an output shaft of the speed reducer is connected with the winding drum, the first-stage brake is mounted on the input shaft between the speed reducer and the electromotor, a second-stage brake is mounted on the input shaft on the other side of the speed reducer, a third-stage brake is mounted on the output shaft on the other side of the speed reducer corresponding to the winding drum, and the first-stage brake, the second-stage brake and the third-stage brake are respectively controlled by the electric control box. The windlass has the advantages of simple structure, scientific and reasonable design, low cost, long service life, powerful braking function and accurate lifting position control, and effectively increases the hoisting quality.
Description
Technical field
The utility model belongs to winch field, especially a kind of novel intelligent multistage brake winch.
Background technology
The tradition winch only has a drg, and drg adopts electromagnetic brake or hydraulic braking more, and the electromagnetic brake drg adopts normally closed form, and during motor start-up, band-type brake is opened, and closes after outage, usually causes weight to banish because band-type brake is ineffective; The braking effect of hydraulic braking is higher than electromagnetic brake, but equally can still produce a certain amount of displacement after braking because braking force makes weight not, above-mentioned winch structure braking function is poor, landing position inaccuracy, reduced lifted load, the ineffective accident of braking has even occured.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of novel intelligent multistage brake winch is provided, this winch is simple in structure, design science reasonable, cost is lower, service life is long, braking function is strong, the landing position control is accurate, has effectively improved lifted load.
The utility model solves its technical matters and is achieved through the following technical solutions:
a kind of novel intelligent multistage brake winch, comprise pedestal and rack-mounted reel, retarder, electrical motor, first order drg and electric appliance control box, the input shaft of retarder connects electrical motor, the output shaft of retarder connects reel, first order drg is installed on the input shaft between retarder and electrical motor, it is equipped with a second stage drg on the input shaft of retarder opposite side, third stage drg is installed on the output shaft of the opposite side of the reductor corresponding with reel, first order drg, second stage drg and third stage drg are controlled by electric appliance control box respectively.
And described first order drg is magnet stopper or hydraulic brake.
And described second stage drg is magnet stopper or hydraulic brake.
And described third stage drg is magnet stopper or hydraulic brake.
Advantage of the present utility model and beneficial effect are:
1, this novel intelligent multistage brake winch comprises pedestal and rack-mounted reel, retarder, electrical motor, first order drg and electric appliance control box, the input shaft of retarder connects electrical motor, the output shaft of retarder connects reel, first order drg is installed on the input shaft between retarder and electrical motor, it is equipped with a second stage drg on the input shaft of retarder opposite side, third stage drg is installed on the output shaft of the opposite side of the reductor corresponding with reel, first order drg, second stage drg and third stage drg are controlled by electric appliance control box respectively, this winch is simple in structure, design science is reasonable, cost is lower, service life is longer, braking function is strong, the landing position control is accurate, effectively improved lifted load.
2, after the utility model increases the multistage brake device, make that the reel of braking retardation can be static from moving within very short time originally, improved the handling of winch, make lifting accurately operation become possibility.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
a kind of novel intelligent multistage brake winch, comprise pedestal 8 and rack-mounted reel 6, retarder 3, electrical motor 7, first order drg 5 and electric appliance control box 10, the input shaft 9 of retarder connects electrical motor, the output shaft 4 of retarder connects reel, first order drg is installed on the input shaft between retarder and electrical motor, it is equipped with a second stage drg 2 on the input shaft of retarder opposite side, third stage drg 1 is installed on the output shaft of the opposite side of the reductor corresponding with reel, first order drg, second stage drg and third stage drg are controlled by electric appliance control box respectively, first order drg is magnet stopper or hydraulic brake, second stage drg is magnet stopper or hydraulic brake, third stage drg is magnet stopper or hydraulic brake.
When the utility model stop button starts, electrical motor quits work, this moment, electric appliance control box control first order drg and second stage drg two were worked simultaneously, and reel slows down, and electric appliance control box is by the work of programming control third stage drg, this moment, three drgs were worked simultaneously, reel stops, and the weight braking that promotes or pull is when electric appliance control box starts again, first order drg, second stage drg and third stage drg are opened simultaneously, and winch continues to start working.The design makes that originally the reel of braking retardation can be static from moving within very short time, has improved the handling of winch, make lifting accurately operation become possibility.
