Abstract
The utility model discloses a kind of forced brake type electric hoist, including reel, a circle ratchet is provided with the reel, speed induction machine is provided with the output shaft of the reel, the speed induction machine is connected on rotational speed governor, and connection support plate is provided with the outside of the reel, brake bar is provided with the connection support plate, the brake bar is fixed on connection support plate by eccentric wheel, and the brake bar is connected on rotational speed governor by telescopic rod.The beneficial effects of the utility model：The setting of speed sensor can perceive the rotating speed of reel, during more than setting speed, rotational speed governor will control brake component to work, and pawl is engaged with ratchet, reel is steadily stopped, avoids electric block whereabouts from injuring staff by a crashing object or break the phenomenon of lifting cargo.
Description
Technical field
Hoisting machinery technical field is the utility model is related to, relates in particular to a kind of forced brake type electric hoist.
Background technology
Electric block is lifting industry commonly used equipment, to prevent from occurring in operation pulleying and suddenly power-off or other are urgent
In the case of whereabouts out of control, be generally provided with brake, general brake is all provided in the brake started on motor or reel
Car band brake or disk brake.The deficiency of this brake is to be unable to emergency braking, is stopped since accident to complete
Need to slide certain distance, longer a reaction process and moderating process need to be passed through, remain to the generation to cause the accident.
Utility model content
The problem of in correlation technique, can be under out of control the utility model proposes a kind of forced brake type electric hoist
Emergency braking when falling.
To realize above-mentioned technical purpose, what the technical solution of the utility model was realized in：
A kind of forced brake type electric hoist, including reel, are provided with a circle ratchet on the reel, the reel it is defeated
Speed induction machine is provided with shaft, the speed induction machine is connected on rotational speed governor, the company of being provided with the outside of the reel
Support plate is connect, brake bar is provided with the connection support plate, the brake bar is fixed on connection support plate by eccentric wheel, the system
Lever is connected on rotational speed governor by telescopic rod.
Further, the top of the brake bar is equipped with touching lever, and the lower section of the brake bar is equipped with pawl.
Further, the telescopic rod is fixed by a pin on the touching lever above brake bar.
Further, it is provided with runner above the touching lever.
Further, the speed induction machine is provided outside protective cover.
The beneficial effects of the utility model：The setting of speed sensor can perceive the rotating speed of reel, more than setting speed
When, rotational speed governor will control brake component to work, and pawl is engaged with ratchet, and reel is steadily stopped, avoids electronic calabash
Reed whereabouts injures staff by a crashing object or breaks the phenomenon of lifting cargo.
