Problems solved by technology
This technology cannot detect the slippage of the elevator traction rope through the brake detection device, and thus cannot effectively prevent the elevator from slipping
[0006] 3) The above technology uses an independent rope clamp to prevent the elevator from slipping, and the rope clamp itself needs to pass the safety certification of the characteristic equipment, which increases the manufacturing cost of the elevator

The invention discloses an elevator car sliding preventing control device. The control device comprises a photoelectric detecting module used for detecting the rotating condition of a hoisting rope guide wheel during leveling of an elevator car , a control module used for controlling the on-off state of a whole device circuit and performing processing according to a detection result of the photoelectric detecting module, a braking module used for vising a car guide rail according to commands sent by the control module and stopping sliding of a car, and a power module used for supplying power to the photoelectric detecting module and the control module. By adopting the control device, the situation of the car sliding of the elevator can be stopped in time, the control device is safe and effective, and the structure is simple.
Description
technical field [0001] The invention relates to the technical field of elevator detection and control, in particular to an elevator anti-rolling control device. Background technique [0002] Elevator "rolling" is one of the main causes of elevator accidents in recent years. At present, in the mechanical system and electrical control system of the elevator, there is no effective detection or control unit to detect and control the "sliding car" action that occurs when the elevator opens and closes the door on the leveling floor. The difficulty lies in the fact that it is difficult to detect the abnormal movement of the elevator, especially the "rolling" of the elevator caused by the slippage of the elevator traction rope. The domestic existing technology of detecting the slippage of the transmission belt by installing a photoelectric switch on the transmission belt is also difficult to be used in the elevator system. For the detection of elevator "rolling car" and the detect...
