Device for releasing lift safety device

Abstract

The invention discloses a device for releasing a lift safety device. The device for releasing the lift safety device structurally comprises an intelligent control safe transmission device, an installation plate, a sliding frame, a combination frame, a wall, a safety sliding door, a controller, a load block and a cabin body. The cabin body is located on the inner surface of the sliding frame and isconnected with the sliding frame in a clearance fit manner. The combination frame is fixedly connected to the inner surface of the sliding frame in a welded manner. The installation plate is perpendicularly connected to the upper surface of the sliding frame and fixedly connected with the sliding frame. The intelligent control safety device is located on the upper surface of the installation plate and fixedly connected with the installation plate. The device for releasing the lift safety device can achieve the purposes that when a lift conducts taking up and paying off, the slip phenomenon ofthe lift is avoided, the lift safety device can conduct clamping and fixing when the descending speed of the lift is excessively rapid, the lift can be protected against route shift, and therefore the lift safety device is more perfect.

Description

technical field [0001] The invention relates to a device for releasing an elevator safety device, which belongs to the field of elevators. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. According to the speed, it can be divided into low-speed elevators (below 1 m / s), f...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a device for releasing the elevator safety device, so as to solve the problem that the elevator cannot be slippery when the elevator is retracted, and at the same time, the device cannot be used when the elevator descends. Clamping and fixing when the speed is too fast, and the elevator cannot prevent the deviation of the line, so that the device cannot be more perfect
