Abstract

The application discloses a magnet brake used for lifting equipment. The magnet brake has the advantages that brake blocks and a brake disc are separated completely when in power-on and pull-in, the brake effect is good, the noise is low, the comfort feeling is good, the reliability is high and the service life is prolonged. The magnet brake comprises a brake seat, an armature, a horseshoe, an electromagnet, the brake disc and the brake blocks; the electromagnet is mounted on the brake seat; the horseshoe and the armature are arranged on the left and right sides of the brake disc respectively; the brake blocks include a first brake block and a second brake block; the first brake block is arranged on the right side of the horseshoe; the second brake block is arranged on the left side of the armature, and the right side of the armature is close to the electromagnet; the brake disc is mounted on a tractor of the lifting equipment; a pin is mounted on a support plate of the tractor; the left part and the right part of the pin are connected with the horseshoe and the armature in a sliding manner respectively; a flange is arranged at the right end of the pin and positioned in a groove in the right side of the armature; a rubber ring sleeves the middle part of the pin; the radial center of the rubber ring and that of the brake disc are in the same line; the brake seat, the support plate and the horseshoe are fixedly connected.

Description

Technical field [0001] The invention belongs to the technical field of electromagnetic brakes, and specifically relates to an electromagnetic brake used for lifting and hoisting equipment, which mainly includes elevator traction machines, cranes and the like. Background technique [0002] With the rapid development of the elevator industry, my country's elevator market has higher and higher requirements for elevator technology and product quality. The performance of elevators depends largely on the performance of elevator traction machines. Electromagnetic brake is one of the most important safety components of elevator equipment. Its performance and working status are directly related to the safety of elevator equipment and elevator users. The working process is: when the traction machine hauls the car to the stair stop, the elevator traction machine requires braking performance at this time, and the brake set on the traction machine locks the brake pads and the brake disc after...
