Abstract
The utility model discloses a brake applied to a main lifting electric motor of a tower crane. The brake is characterized in that the brake is provided with a field core, a brake disc with an armature, and a brake disc; an electromagnetic coil is arranged in the field core; a frictional disk is arranged between the brake disc with the armature and the brake disc; and a brake spring is arranged between the brake disc with the armature and the field core. The brake has the benefits of compact structure, small volume, light weight, short response time and high reliability and can effectively stop brake safety accidents.
Description
Technical field
The utility model discloses a kind of brake equipment, especially be fit to master on the tower crane (abbreviation tower crane) motor braking that hoists and use.
Background technology
In the master of tower crane (abbreviation tower crane) hoists electrical motor; The brake equipment vitals that is absolutely necessary; The effect of brake equipment is that electronic function is stopped operating in needs; Otherwise will cause the accident, for the bigger master of the load electrical motor that hoists, the consequence of accident is very serious.So the requirement of brake equipment is that compact conformation, volume are little, in light weight, response time is short, reliability is high.Generally drg is backward in technique, can not satisfy the requirement of tower machine of new generation.
Summary of the invention
The purpose of the utility model provides and a kind ofly is applied to the tower crane master and hoists the drg of electrical motor to remedy the prior art deficiency.
The utility model for realizing the technical scheme that purpose adopts is: be applied to the hoist drg of electrical motor of tower crane master; It is characterized in that: be provided with field core; Magnet coil is arranged in the field core; Band armature brake disc and brake disc are arranged in being provided with, between band armature brake disc and brake disc, friction disc is arranged, between band armature brake disc and field core, retarding spring is arranged.
The beneficial effect of the utility model is: these article compact conformation, volume is little, in light weight, response time is short, reliability is high, can stop the brake safe accident by actv..
Pass through embodiment below, and combine accompanying drawing that the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Embodiment: when normal operation; The tower crane driver operation master motor operation that hoists comes normal operation (friction disc 2 is installed on the main motor reel that hoists and rotates thereupon); During this time, drg is in release position: the magnet coil of field core 5 gets electric, produces magnetic force; Magnetic force holds the armature in the band armature brake disc 4, and band armature brake disc 4 is connecting on the guide shaft 3 move right (at this moment being with armature brake disc 4 compressing retarding springs 6).Friction disc 2 breaks away from brake disc 1 and band armature brake disc 4.
When running to appropriate position; Cut off the power supply of the main electrical motor that hoists; Start drg simultaneously: break off the power supply of the magnet coil of field core 5, magnetic force disappears, and band armature brake disc 4 resets under the pressure of retarding spring 6; Friction disc 2 is fitted with brake disc 1 and band armature brake disc 4 end faces, forms braking.
