Abstract

The invention relates to the technical field of elevator industry, in particular to a block type electromagnetic brake of an elevator. The block type electromagnetic brake of the elevator comprises an electromagnet and a housing, wherein the electromagnet, a female iron core and a male iron core are all arranged in the housing, one end of the female iron core and one end of the male iron core are hinged with the top ends of two brake arms through connection rods after respectively stretched out of the housing, the middle end of each brake arms is hinged with one end of a cantilever, the bottoms of the two brake arms are connected together through a screw and a nut, a brake spring is arranged between the nut and the bottom end of each brake arm, brake tiles are symmetrically arranged on the inner walls of the two brake arms, brake rubber blocks are fixedly arranged on the outer surfaces of the brake tiles, and the brake tiles are connected with the brake arms through air bags. When the block type electromagnetic brake of the elevator is used, impact force generated during the brake process is greatly reduced, and therefore the block type electromagnetic brake of the elevator is stable in performance, low in noise, and reliable in braking, and facilitates use life extension of a traction machine. The block type electromagnetic brake of the elevator has the advantages of being simple in structure, reasonable in arrangement, low in fabricating 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...
