Problems solved by technology

[0008] b. Once the safety brake of the elevator is activated, the main motor will be forced to run quickly due to the insufficient friction coefficient between the halyard and the halyard, which will cause idling and fail to drive
[0009] c. The passenger space of the elevator and the halyard generally have a safety factor for overload operation, so they can allow safe overload operation in emergencies, but because of the limitation of the safety brake, it is impossible to safely transport the elevator by force in the event of a fire personnel
[0010] d. There is no backup escape device in the existing elevator, and it depends entirely on the main motor to operate normally. If the main motor is damaged or there is no power supply, there will be no way to escape

Embodiment Construction

[0028] The invention provides a safety protection and escape drive device design for an elevator hoisting rope.

[0029] In order to enable them to further understand the structural design and technology of this creation, I would like to explain it with the accompanying drawings:

[0030] refer to figure 1 , figure 2 As shown, it is a front view and a side view of a preferred embodiment of the present invention, the main motor 10 is used to drive the halyard operation wheel 11 by the main motor spindle 15, and the halyard operation wheel 11 can be driven to lift The cable 12 drives the elevator to go up and down, and a brake 13 is provided between the main motor 10 and the hoisting cable operation wheel 11, and a gear 14 is provided on one side of the hoisting cable operation wheel 11, and a release brake lever 16 is provided above the brake 13 for dialing. The lever device 26 is toggled to release the brake;

[0031] The operation cable 20 is connected to the side of the ...

Abstract

The present invention is a kind of lift safety device for use in abnormal emergency condition. The lift safety device includes a cable pressing wheel to hold the elevating cable to increase friction resistance and avoid sliding, and an auxiliary motor coupled via small gear to the elevating cable gear. After the brake is released and the start switch is turned on, the main motor may be operated electrically or the auxiliary motor is operated with the spare power source, the lift is driven to place safely.

Description

technical field [0001] The invention relates to a safety protection and escape driving device for an elevator lifting cable, which solves the restriction on the use of a safety brake and achieves the purpose of safety protection and escape from difficulties. Background technique [0002] High-rise buildings are the product of urbanization, which has also created a culture of elevators. Elevators have become a must-have for high-rise buildings. If the elevator is properly designed, the elevator may become a tool for saving people when necessary. In an emergency, it may become a harmful appliance, and its elevator is a life-saving tool or a harmful appliance, depending on whether the designer's consideration is thorough. [0003] Such as the safety brake that is generally used today, it may become a harmful device in an emergency, because at present all elevators are equipped with so-called safety brakes between the elevator car and the lifting slide rail. The purpose of the ...
