Problems solved by technology

[0003] Among them, most of the brakes of the traction machine use magnets to open or close the brakes. When the elevator is running, the brakes are in the open state. Therefore, the magnets are required to have sufficient electromagnetic attraction to ensure the normal operation of the elevator. However, due to space and Due to cost constraints, the size of the brake magnet is also subject to certain restrictions

Abstract

The invention discloses a braking brake, comprising a first brake arm and a second brake arm arranged at two sides of a brake pulley; a first brake block and a second brake block connected against the brake pulley are respectively arranged on the first brake arm and the second brake arm; one end of the first brake arm and one end of the second brake arm are respectively articulated on a frame; the braking brake also comprises a motor, a screw connected with the output end of the motor; a second nut matching the screw and a tensioning piece; the motor is arranged on the other end of the first brake arm; the second nut is arranged on one end of the screw; the end is far from the motor; the second nut is fixedly connected with the other end of the second brake arm; the screw runs through the second nut and the tensioning piece; one end of the tensioning piece is connected with the end of the screw; the other end of the tensioning piece is connected against the second brake arm. The braking brake of the invention is safe, reliable, economic and practical.

Description

technical field [0001] The present invention relates to the field of elevators, more specifically, to a braking brake. Background technique [0002] Lifting equipment commonly used in buildings for vertical transportation. Elevators are mainly composed of traction machines (winches), guide rails, counterweight devices, safety devices (such as speed limiters, safety gears and buffers, etc.), signal control systems, car elevators, etc. Composed of compartments and hall doors. [0003] Among them, most of the brakes of the traction machine use magnets to open or close the brakes. When the elevator is running, the brakes are in the open state. Therefore, the magnets are required to have sufficient electromagnetic attraction to ensure the normal operation of the elevator. However, due to space and Due to cost constraints, the size of the brake magnet is also subject to certain restrictions. Contents of the invention [0004] In view of this, the main purpose of the present in...
