Abstract

The utility model relates to an electric hoist, comprising a motor (1), a motor reducer (15), a drum (3), a drum shell (2), a first brake device (16) and a second brake device (17), wherein the motor reducer (15) is mounted on one end of the drum shell (2) and the motor is set at the lateral surface of the drum shell (2) in rigid couple with the reducer (15) and the first brake device (16) and the second brake device (17) are respectively set on the two ends of the drum shell (2) and the axle of the motor (1) is parallel with the drum output axle (14) and the first brake device (16) is connected with the drum output axle (14) and the second brake device (17) is connected with the drum output axle (18). Using the above technical proposal, the electric hoist conquers the defect of the prior technique that the brake is hysteretic. The electric hoist has more reliable performance.

Description

A kind of electric block

Technical field

The utility model relates to a kind of weight-lifting equipment, relates in particular to a kind of electric block.

Background technology

Electric block is a weight-lifting equipment commonly used in producing, the prior art electric block, lifting motor places an end of reel shell, the other end is provided with motor reducer, the output shaft of motor is connected with elastic coupling with the tween drive shaft of reel, reducer input shaft is connected with fast coupling with the tween drive shaft of reel, by the brake equipment that motor is installed motor is directly braked, motor quits work reel by retarder again, step connection, and the reel that is difficult to the electric block of assurance mode of operation at the uniform velocity rotates, reel rotates decentraction, steel rope skids, and braking retardation makes the work piece of lifting by crane glide and falls in addition; Steel rope can not be wrapped on the reel in order simultaneously, the two ends that steel rope is whipped into reel occur, even wire cable rupture occurs, can't work, and by forced-stopping machine, the defective that may cause safety misadventure to take place.

The utility model content

Problem to be solved in the utility model provides a kind of electric block, its objective is that overcoming the roll transmission device step connection causes electric gourd drum at the uniform velocity not rotate, and the defective that steel rope is whipped into the reel two ends occurs, and the electric block safety performance is improved.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of electric block, comprise electrical motor, motor reducer, reel, reel shell, the two ends of reel shell are respectively arranged with first drg and second drg, described motor reducer is installed in an end of reel shell, and electrical motor places the side of reel shell and affixed with retarder.

Described electrical motor is a braking motor, and the axis of electrical motor is parallel with the line of centers of reel output shaft.

Described first drg is connected with the reel output shaft, and second drg is connected with reel end output shaft.

The described reel shell other end relative with motor reducer is provided with clump weight.

A kind of electric block of the utility model adopts technique scheme, compared with prior art, directly uses braking motor, and motor directly links to each other with retarder, has overcome the defective of prior art braking retardation, has improved the safety performance of electric block use; Motor is directly braked, and has improved braking effect, has reduced braking time; The electric block glancing impact can produce than high pulling torque, adopts technology originating party case of the present utility model, and interior being passed with retarder by an integral shaft of reel links to each other, and improved its safety performance greatly; Motor directly links to each other with retarder, has increased the monolateral weight of reel, and the other end increases clump weight, keeps the balance of electric block.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the scheme drawing of a kind of electric block of the utility model.

Be labeled as among the figure: 1, braking motor; 2, reel shell; 3, reel; 4, guide rope device; 5, steel rope; 6, reel side bearing support plate; 7, clump weight; 8, motor output gear; 9, first gear; 10, high speed shaft; 11, second gear; 12, middling speed axle; 13, the 3rd gear; 14, reel output shaft; 15, motor reducer; 16, first drg; 17, second drg.

The specific embodiment

Contrast accompanying drawing below,, the specific embodiment of the present utility model is described in further detail by description to embodiment.

The scheme drawing of a kind of electric block of the utility model shown in Figure 1, comprise electrical motor 1, motor reducer 15, reel 3 and reel shell 2, motor reducer 15 is installed in an end of reel shell 2 and drives reel 3 and rotates, electrical motor 1 is a braking motor, be installed in the same end of reel 3 with motor reducer 15, by first gear 9 engagements of motor output gear 8 with motor reducer 15, first gear 9 drives second gear 11 by high speed shaft 10, second gear 11 drives the 3rd gear 13 by middling speed axle 12, the 3rd gear 13 drives reel 3 by slow-speed shaft 14 and rotates, electrical motor 1 places the side of reel shell 2 and affixed with retarder 15, also be provided with guide rope device 4 on the reel, steel rope 5 better is wrapped on the reel 3; Reel shell 2 and the motor reducer 15 relative other ends are provided with clump weight 7, are used for the balance electric cucurbit, because what use is braking motor, motor 1 and retarder 15 direct connections have overcome the defective of braking retardation.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
