Abstract

The invention relates to the technical field of the elevator industry, in particular to a block-type electromagnetic brake for an elevator, which includes an electromagnet and a housing. The electromagnet, female iron core and male iron core are all arranged inside the housing, and the female iron core and male iron core One end of the brake arm is hinged with the top end of the brake arm through a connecting rod after extending out of the housing, the middle end of the brake arm is hinged with one end of the cantilever, and the bottom ends of the two brake arms are connected by a screw rod and a nut; Brake springs are arranged between the bottom ends of the booms; brake tiles are symmetrically arranged on the inner walls of the two brake arms, and brake rubber blocks are fixedly arranged on the outer surface of the brake tiles, and the brake tiles are connected to each other through the air bag. The brake arm is connected. When the invention is used, the impact force in the braking process is greatly reduced, the performance is stable, the noise is small, the braking is reliable, and it is beneficial to prolong the service life of the traction machine. The invention has the advantages of simple structure, reasonable setting, low production cost and the like.

Description

technical field [0001] The invention relates to the technical field of the elevator industry, in particular to a block type electromagnetic brake of an elevator. Background technique [0002] The brake is an extremely important safety component of the traction elevator. At present, the brake on the elevator traction machine is composed of a spring and an electromagnet. When the traction machine is working normally, the brake block on the brake leaves the traction under the action of the spring The brake shaft on the traction machine, when braking is required, the electromagnet is energized, and the armature of the electromagnet overcomes the spring force to drive the brake block to press the brake shaft on the traction machine to stop the traction machine quickly. This type of brake has a large impact force and poor stability during the braking process, and the impact torque on the traction machine is large, which affects the life of the traction machine. Therefore, it is n...
