Abstract
The utility model relates to a braking electric block, which comprises an electric motor (1), a reel (3), a reel output shaft (19) and a reel casing (2), wherein a decelerating mechanism (15) positioned at the end part of the reel casing (2) is arranged between the electric motor (1) and the reel output shaft (19); and brakes are arranged at both ends of the reel (3) respectively. Because the braking electric block of the utility model adopts the technical scheme, the braking effect of the electric block is ensured; the problem that the skidding and the sliding of the electric block is effectively avoided; the safety performance of the electric block is improved; the service life of the equipment is improved; the life safety of operators is ensured; and the cost of the equipment is reduced.
Description
Technical field
The utility model relates to a kind of weight-lifting equipment, relates in particular to a kind of brake electric hoist.
Background technology
Electric block is a weight-lifting equipment commonly used in producing, the motor driving reducer motion, retarder is connected with reel and drives the reel rotation, and the suspension hook that the end of the steel rope that twines on the reel is installed is sling goods, and the electric block motion is transported to the appointed place with goods.For guaranteeing lifting and the safety of transporting, electric block all is equipped with brake equipment, guarantees its personal safety of transporting safety and operating personal aborning.Prior art is that brake equipment is installed on electrical motor, directly electrical motor is braked, then brake retarder and and then brake electric hoist, the brake equipment that is directly installed on the electrical motor is connected with the motor high speed shaft, for a long time use, wearing and tearing can appear, cause braking not play a role, appearance can not be braked, and steel rope skids, the weight that is lifting by crane falls, even the life security that jeopardizes operating personal.
The utility model content
Problem to be solved in the utility model provides a kind of electric block, its objective is that effective solution electric block skids, slips the problem of car, improves its safety performance.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of brake electric hoist, comprise electrical motor, reel, reel output shaft and reel shell, be provided with the speed reduction gearing that is positioned at the reel outer casing end between described electrical motor and the reel output shaft, the reel two ends are respectively equipped with drg.
Described motor output shaft line of centers is parallel with reel output shaft line of centers.
Described motor output shaft is provided with motor output gear, described speed reduction gearing comprise and motor output gear ingear first gear, second gear, first gear and second gear between high speed shaft, the 3rd gear, second gear and the 3rd gear between the middling speed axle and the slow-speed shaft between the 3rd gear and the reel output shaft.
The speed reduction gearing opposite end of described reel shell is provided with clump weight.
A kind of brake electric hoist of the utility model, adopt technique scheme, compared with prior art, the utility model adopts respectively increases a drg at the two ends of reel, and drg links to each other with the slow-speed shaft of retarder, has reached good braking effect, single-stage braking by prior art has become multistage brake, guarantee the braking effect of electric block, effectively solved electric block and skid, slip the problem of car, improved the safety performance of electric block; Multistage brake, improved braking effect, shortened braking time, if the malfunctioning situation of braking motor takes place, drg can work independently electric block is braked, and has avoided motor to break down and has caused the generation of industrial accident, is connected with the speed reduction gearing slow-speed shaft by drg, improve service life of equipment, ensured the life security of operating personal; The electric block glancing impact can produce than high pulling torque, has reduced the input of equipment, has reduced equipment cost.
