Elevator opening-closing traction integrated type emergency control equipment

Abstract

The invention discloses elevator opening-closing traction integrated type emergency control equipment. The elevator opening-closing traction integrated type emergency control equipment comprises a first displacement conversion device, a second displacement conversion device, a handle, a band-type brake opening-closing switch and a lift car traction device; the handle rotates around a fixed point,and the rotating path comprises a first stroke and a second stroke, and taking the initial position as reference, the handle passes the first stroke and then the second stroke during rotating; the first displacement conversion device is arranged on the path of the first stroke, and the first displacement conversion device is in transmission connection with the band-type brake opening-closing switch; and the second displacement conversion device is arranged on the path of the second stroke, and the second displacement conversion device is in transmission connection with the lift car traction device. Two transmission modules are successively arranged on the movement stroke of the handle and are in transmission connection with the band-type brake opening-closing switch and the lift car traction device correspondingly, so that two different control operations can be carried out through one handle, and flexibility and the reaction time of controlling are improved.

Description

technical field [0001] The invention relates to the field of rescue equipment for a gearless traction elevator, in particular to an elevator opening and closing traction integrated emergency control equipment. Background technique [0002] During the use of the traction elevator, it is difficult to avoid failure shutdown. After a failure, it is necessary to operate from the outside of the elevator shaft, and open the traction machine brake to achieve leveling, so as to release passengers. However, when the mass of the car side and the mass of the counterweight side are close to balance, even if the brake of the traction machine is opened, the car cannot move up or down. At this time, it is necessary to use a certain method to break the balance on both sides, and to drive the elevator car to move by applying an external force. In the current industry field, the ways to achieve both functions are mainly divided into mechanical and electrical methods, and one of the common cau...

AI Technical Summary

Problems solved by technology

[0003]The problem is that in the existing rescue equipment, the two steps of releasing the brake and moving the car are separated from the operation equipment, and it is difficult for a single person to operate

Moreover, during the process of controlling the movement of the car after the brake is released, the system resistance and the mass on both sides of the car and the counterweight may change, causing the car to accelerate out of control

If the rescuers fail to reach the brake in time and switch it to a tight state, causing the car to rise or fall out of control, the lives of the passengers in the car will be in danger
