Abstract
The utility model discloses a double-braking motor hoist, which belongs to a crane. The utility model solves the technical problem that one double-braking motor hoist, the braking reliability of which is higher, is designed. The double-braking motor hoist comprises a motor brake and one brake arranged on one end of a reel shaft, wherein the brake arranged on one end of the reel shaft can be an electromagnetic brake and can be a power hydraulic block brake. The utility model is used for the crane.
Description
Technical field
The utility model relates to a kind of hoisting crane, particularly a kind of double-brake electric hoist.
Background technology
Existing electric block is to rely on motor braking.This electric block is single braking, will have an accident in case electromotor brake is malfunctioning.
Summary of the invention
The utility model technical issues that need to address are a kind of electric blocks of design, and its braking reliability is higher.The technical solution of the utility model is, a kind of double-brake electric hoist, and it includes electromotor brake, it is characterized in that: the end in drum shaft also is provided with a drg.At the set drg of an end of drum shaft is magnet stopper.At the set drg of an end of reel is the power hydraulic pressure block brake.The utility model has been owing to set up the drg of a braking scroll bar again at the other end of electric block, thereby this electric block and existing technology relatively have a higher advantage of deceleration and stopping performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the left view of Fig. 1.
The specific embodiment
In conjunction with above accompanying drawing the utility model is described in detail, this double-brake electric hoist, the one, motor braking, the 2nd, increase a drg in addition, the drg that is increased can be power hydraulic pressure block brake or electromagnetic brake, this drg is located at the direct brake drum axle of left end of reel 2, is provided with coupler 4 between electrical motor 5 and the retarder 3.Above-mentioned power hydraulic pressure block brake and electromagnetic brake are existing braking technology.
