Elevator safety monitoring device

Abstract

The invention relates to an elevator safety monitoring device, and relates to the field of elevator safety. The elevator safety monitoring device comprises a traction motor, a mounting seat, a levelness detection assembly, a slip detection assembly, a control module and an elevator alarm module; the traction motor comprises a shell and a traction wheel, the mounting seat is installed on the shell,the mounting seat comprises a bottom plate and a vertical plate, and the vertical plate is perpendicular to the bottom plate and located on the side, far away from the shell, of the bottom plate; andthe levelness detection assembly is arranged between the bottom of the traction wheel and the upper surface of the bottom plate, the slip detection assembly is arranged between the outer side surfaceof the traction wheel and the vertical plate, and the control module is electrically connected with the levelness detection assembly and the slip detection assembly, and is used for controlling the elevator alarm module to be started and closed according to a detection result. According to the device, whether the traction wheel is horizontal or has a slipping tendency or not can be effectively monitored, so that the device is safer, the structure is stable, the installation is simple, and the manufacturing is simpler.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to an elevator safety monitoring device. Background technique [0002] As a common vertical lifting tool, traction elevators are widely used in large commercial buildings or office buildings. Compared with hydraulic elevators, traction elevators have the advantages of high transmission height, high acceleration, and rapid lifting. The use range of traction elevators is also very large. widely. The traction elevator is different from the hydraulic elevator. Its power source comes from the counterweight and the traction motor. The traction motor includes a traction wheel and a traction rope. Traction sheave and traction rope are important safety components of the elevator. In recent years, higher requirements have been put forward for its detection, accuracy and safety. Due to the different elevator specifications, sizes and tonnages, the installation of the traction The pos...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: since the above-mentioned monitoring device can only monitor whether the traction sheave is level, if the traction sheave is loose, once the traction sheave rotates at a high speed, the traction sheave will have a horizontal outward direction. The trend of slipping and detaching, and the above-mentioned monitoring device cannot monitor this risk, so it needs to be improved, and the structure of the above-mentioned monitoring device is relatively complicated, and the production and installation are relatively cumbersome
