Embodiment Construction

[0012] An elevator safety control system of the present invention is an improvement on the existing basis, and a set of auxiliary control system is added on the existing elevator setting and basis, such as figure 2 As shown, the driving gear that provides power to the elevator door gear drives the elevator door gear to rotate, and the elevator door gear drives the opening or closing of the elevator door. By installing a torque limiter on the elevator door gear, the maximum torque when driving the elevator door to open or close is limited. For example, the maximum value of the torque limiter is set to 1 kgf, that is, when the elevator doors are closed, the maximum clamping force between the elevator doors is 1 kgf, so that even if the elevator door clamps people, it will not cause harm to people. Such as image 3 As shown, a locking device is installed on both sides of the elevator guide rail close to the elevator door on each floor. The locking device is composed of a vertica...

Abstract

The invention relates to the field of elevators, in particular to an elevator provided with a sub-control system for detecting the running state of the elevator. An elevator safety control system comprises an elevator main control system, an elevator door gear, a driving gear providing power for the elevator door gear, an elevator guide rail, an elevator input port, a sub-control system, a torsion limiting device installed on the elevator door gear, and locking devices arranged on the two sides of the elevator guide rails and close to each layer of elevator door. By adopting the independent sub-control system in parallel with the main control system, the elevator can be monitored in real time during running, and the safety of the elevator is improved.

Description

[0001] The invention relates to the field of elevators, in particular to an elevator with a secondary control system for detecting the running state of the elevator. Background technique [0002] There are more and more high-rise buildings at present, and elevators are an indispensable device for high-rise buildings, but the current elevator safety is still worthy of vigilance, and there are often news reports about safety accidents in elevators. Contents of the invention [0003] The technical problem to be solved by the invention is: how to improve the safety of the existing elevators. [0004] The technical scheme adopted in the present invention is: a kind of elevator safety control system, comprises elevator main control system, elevator door gear, the driving gear that provides power for elevator door gear, elevator guide rail, elevator input port, auxiliary control system, installed in the elevator The torque limiter of the door gear, the locking device installed on b...
