Problems solved by technology

[0002] At present, machine-room-less elevators are developing very rapidly. With the further popularization and application of machine-room-less elevators, the demand for machine-room-less elevators in the market is also increasing. Neglected problem, the main engine of the existing machine room-less elevator is installed in the shaft, people cannot directly operate the main machine to release the brake like the machine room elevator, and need to operate the brake release device outside the shaft
At present, machine-room-less elevators generally operate the electrical switch outside the shaft to release the brakes electrically, but elevators often fail to release the electric brakes due to faults in the brake coil and terminal block, which is prone to failure and cannot guarantee the safety of personnel.

Abstract

The invention relates to an elevator brake releasing device. The elevator brake releasing device comprises a first brake, a second brake, a first support and a second support, wherein the first brake and the second brake are symmetrically arranged on an elevator host. The elevator brake releasing device further comprises a control rope, an outside well releasing operating mechanism used for tensioning or releasing the control rope, a first pull rod and a second pull rod, wherein the first pull rod and the second pull rod are arranged in a crossed mode. One end of the first pull rod is rotationally connected with the first support, and a pulley is connected to the other end of the first pull rod. The first pull rod is provided with a movable groove. One end of the second pull rod is movably connected with the second support. The other end of the second pull rod penetrates through the movable groove and is connected with one end of the control rope. The other end of the control rope winds around the pulley to be connected with the outside well releasing operating mechanism. The first brake and the second brake are connected with the first pull rod and the second pull rod respectively. According to the elevator brake releasing device, releasing is carried out in a mechanical mode, the problem of failure of the releasing device due to electric failure can be solved, and safety and reliability are achieved. The first pull rod and the second pull rod are arranged in the crossed mode, the synchronism of releasing of the first brake and the second brake is high, and brake force is stable.

Description

technical field [0001] The invention relates to the technical field of elevator brake release, in particular to an elevator brake brake release device. Background technique [0002] At present, machine-room-less elevators are developing very rapidly. With the further popularization and application of machine-room-less elevators, the demand for machine-room-less elevators in the market is also increasing. The neglected problem is that the main engine of the existing machine-room-less elevator is installed in the well, and people cannot directly operate the main engine to release the brake like the machine-room elevator, and need to operate the brake release device outside the well. At present, machine-room-less elevators generally operate the electrical switch outside the well to release the brakes electrically. However, elevators often fail to release the brakes electrically due to faults in the brake coil and terminal block, which is prone to failure and cannot guarantee th...
