Abstract
The invention relates to special machinery, in particular to an elevator safety brake. The inner brake shoe and the outer brake shoe respectively press the inner side and the outer side of the brake wheel to conduct conventional braking, and emergency braking can be achieved through the speed limiterassembly. When the elevator is used, the traction wheel pulls the lift car through the traction rope to achieve normal up-and-down work of the elevator; when the elevator is braked and the left and right double-rotation-direction lead screws rotate, the threaded sliding blocks on the two sides synchronously move inwards, the threaded sliding blocks are connected with the brake arms to rotate inwards, the outer brake shoe seats and the outer brake shoes on the brake arms press the brake wheel tightly, the outer side braking action is completed, and the inner brake shoe seats extend outwards along fourth grooves in the I-shaped beams through the connecting arms; the inner brake shoe is tightly attached to the inner ring of the brake wheel, and the inner brake shoe and the inner ring of the brake wheel are reversely braked, so that the inner side braking action is completed; when the descending speed of the elevator exceeds the safety speed set by the second spring, the throwing block hooks the speed limiting buckle on the fixed outer ring of the speed limiter, and emergency braking is carried out to ensure the safety of passengers in the elevator.
Description
technical field [0001] The invention relates to a special machine, more specifically to an elevator safety brake. Background technique [0002] For example, CN202110563615.5 is an elevator safety brake, which includes a bracket, a coil, a moving iron core, a moving iron core guiding device, a brake shoe, a brake spring and connecting bolts. When the coil is energized, an electromagnetic thrust is generated to separate the brake shoe For the brake disc or wheel on the traction machine, the electromagnetic force disappears when the coil is powered off, so that the brake shoe acts on the brake disc or wheel on the traction machine to form a power-off brake. However, the braking form is single. Today, with higher requirements for elevator safety, it is necessary to improve and optimize the braking form. Contents of the invention [0003] The purpose of the present invention is to provide an elevator safety brake, which can perform conventional braking by pressing the inner an...
