Problems solved by technology

[0002] The electrical interlock arbitrary speed regulating mechanism of the hoist is an important component of the hoist. In the existing electrical interlock arbitrary speed regulating mechanism of the hoist, the hoisting mechanism often cannot meet the requirements of modern lifting performance. When the hoist is running, due to the constant braking torque, a large braking impact is caused, which affects the stability of the hoist and the inability to achieve an accurate stop of the hoist. In the case of accurate parking, multiple clicks are required. Only by moving to stop, frequent clicks reduce the work efficiency, cause unnecessary vibration of the lift, and greatly reduce the service life of the brake electromagnetic coil

Abstract

The invention discloses an electrical interlock and random speed adjustment mechanism of a hoister. A sliding block is connected to the lower end of a brake arm, and a Belleville reset spring is installed on the right side of the sliding block. A brake oil cylinder is installed on the left side of the sliding block, a piston rod is installed at the middle end of the brake arm, and the heads of the two sides of the piston rod abut against the brake arm. An oil supply pipe is arranged on a foot plate, one end of the oil supply pipe is connected with the brake oil cylinder, and the other end of the oil supply pipe is connected with an oil storage cylinder. A lower pedal is connected to the end of one side of the foot plate, and a micro switch is installed on one side of the lower pedal.

Description

technical field [0001] The invention relates to an electrical interlock arbitrary speed regulating mechanism, in particular to an electric interlock arbitrary speed regulating mechanism of a hoist, belonging to the technical field of mechanical braking. Background technique [0002] The electrical interlock arbitrary speed regulating mechanism of the hoist is an important component of the hoist. In the existing electrical interlock arbitrary speed regulating mechanism of the hoist, the hoisting mechanism often cannot meet the requirements of modern lifting performance. When the hoist is running, due to the constant braking torque, a large braking impact is caused, which affects the stability of the hoist and the inability to achieve an accurate stop of the hoist. In the case of accurate parking, multiple clicks are required. Only by moving can the car be stopped. Frequent clicking reduces the work efficiency, more likely to cause unnecessary vibration of the lift, and gr...
