Problems solved by technology

[0002] Refer to Annex 1, which is shown in the second figure of the new application No. 091221162 "Structure Improvement of Elevator Safety Auxiliary Lifting Equipment". In the auxiliary lifting equipment of the prior art, when the gear coupling of the auxiliary motor is carried out, the other rod body is also In the action of releasing the brake, if the auxiliary motor is not damaged, there is no danger in releasing the brake, because the auxiliary motor can drive the elevator up and down; but the problem is: if the auxiliary motor is damaged, the time to find it is often after turning on the power No action can be known, but at the same time the brake has been released at the same time, the auxiliary motor is also damaged without any braking resistance, and the elevator is in a state of free fall, which will cause great danger
[0004] But the problem is: if the auxiliary motor is damaged, the time to find out is often when there is no action after the power is turned on. However, at the same time, the brake has been released at the same time, the auxiliary motor is also damaged without any braking resistance, and the elevator is in a state of free fall. would cause great danger

Embodiment Construction

[0020] In order to make it possible to further understand the structural design and technology of the present invention, it is specifically described as follows in conjunction with the accompanying drawings:

[0021] refer to figure 1 , figure 2 Shown is a schematic diagram of a preferred embodiment of the present invention and its implementation in the elevator car. The elevator car 12 is connected to the drive wheel 11 with a cable 16, and the drive wheel 11 is lifted by the transmission of the main motor 10. When the main motor 10 Or when the elevator fails, the brake 14 acts to lock the mandrel 15, so that the drive wheel 11 cannot rotate, so as to prevent the elevator car from falling, but also because the elevator car 12 is locked and causes people to be trapped in the elevator car, it is impossible to Getting in and out is the shortcoming of the prior art elevator;

[0022] Also because of this, quite a lot of operators have developed the design of relevant elevators...

Abstract

The invention relates to a system for confirming the lift auxiliary self-rescue, which can solve the problem that the damage of present self-rescue guard system can not be detected; with which, only when the auxiliary self-rescue system is normal and coupled normally, the brake can be turned on, to make the auxiliary motor drive the lift to be rescued.

Description

technical field [0001] The invention relates to an elevator auxiliary self-rescue guarantee system, especially when the auxiliary motor is damaged, the brakes are still protected, so that the auxiliary motor is known to be damaged after the brake is released due to escape, and the safety guarantee can also be guaranteed. Background technique [0002] Refer to Annex 1, which is shown in the second figure of the new application No. 091221162 "Structure Improvement of Elevator Safety Auxiliary Lifting Equipment". In the auxiliary lifting equipment of the prior art, when the gear coupling of the auxiliary motor is carried out, the other rod body is also In the action of releasing the brake, if the auxiliary motor is not damaged, there is no danger in releasing the brake, because the auxiliary motor can drive the elevator up and down; but the problem is: if the auxiliary motor is damaged, the time to find it is often after turning on the power No action can be known, but at the s...
