Powerful brake device

Abstract

The invention relates to a powerful brake device. The powerful brake device comprises a motor. The motor is provided with a speed reducer which is connected with a clutch. The output end of the clutch is connected with a drum through a spline. The drum is connected with a brake device. A hub of the brake device is fixed to the drum through bolts. The brake device is provided with a brake shoe and a wheel cylinder. The wheel cylinder is connected with a high-pressure oil inlet which is connected with a high-pressure oil outlet. The high-pressure oil outlet is connected with a gas-liquid pressurization device which is connected with low-pressure gas. According to the powerful brake device, the cutch and the high-power brake device are mainly added, the clutch is added to the drive end of a special electric winch, the brake device is arranged at the other end of the special electric winch, the rotation inertia is reduced, the power consumption is lowered in the braking process, large braking force is provided through drum type braking, the drum rotating at a high speed is rapidly braked, the gas-liquid pressurization device provides braking power, and the powerful brake device has the advantages of being high in running speed, short in braking time and large in braking torque.

Description

technical field [0001] The invention belongs to the field of mechanical design, in particular to a braking device, in particular to a powerful braking device. Background technique [0002] The electric winch is the most common mechanical appliance driven by the electric system. It pulls the goods through the reel. The motor of the ordinary winch rotates and connects the intermediate drive shaft through the spline. The intermediate drive shaft is connected to the reducer, and the reducer passes through The internal and external gears are meshed and transmitted to the reel, thereby driving the reel to rotate. Most ordinary electric winches can provide a small driving force. Generally, the operating speed is 20~30m / min, the braking torque is 6000NM, and the braking time is 0.5S. For left and right occasions, the current situation is: a rail trolley runs at a high speed of 30~35m / S, and the braking time is required to be less than 0.06S to pull the trolley back to its original p...

[0002] The electric winch is the most common mechanical appliance driven by the electric system. It pulls the goods through the reel. The motor of the ordinary winch rotates and connects the intermediate transmission shaft through the spline. The intermediate transmission shaft is connected to the reducer, and the reducer passes through The internal and external gears are meshed and transmitted to the reel, thereby driving the reel to rotate. Most ordinary electric winches can provide a small driving force. Generally, the operating speed is 20~30m / min, the braking torque is 6000NM, and the braking time is 0.5S. For left and right occasions, the current situation is: a rail trolley runs at a high speed of 30~35m / S, and the braking time is required to be less than 0.06S to pull the trolley back to its original position. The braking torque needs to be 14000NM, that is, it needs a strong and fast braking, the existing electric winch device will not meet the requirements
