Abstract

The invention discloses an elevator structure. According to the elevator structure, a detection unit can send a detection signal to a control execution unit when a lift car moves, and the control execution unit can analyze and judge after receiving the detection signal. When the control execution unit judges that the movement of the lift car is normal operation or is generated due to human factors, the control execution unit does not act and is not in contact with a steel wire rope of a speed governor, and the steel wire rope of the speed governor is allowed to move along with the movement of the lift car, namely the movement of the lift car cannot be influenced; and when the control execution unit judges that the movement of the lift car is unintentional movement, the control execution unit acts to clamp the steel wire rope of the speed governor so as to ensure that the steel wire rope of the speed governor cannot move but the lift car moves at this movement, thus a pair of bidirectional safety tongs is triggered to stop the lift car which moves unintentionally so as to prevent a falling accident of the lift car.

Description

[0001] technical field [0002] The present invention relates to an elevator structure. [0003] Background technique [0004] In the prior art, when the car of the elevator moves unintentionally, there is a danger of falling. [0005] Contents of the invention [0006] The object of the present invention is to provide an elevator structure capable of detecting unintentional movement of the elevator car and immediately stopping the car to avoid the danger of falling. [0007] In order to achieve the above object, the technical solution adopted by the present invention is: an elevator structure, including a car that can be lifted and lowered, a traction rope that can drive the car to go up and down, for the traction rope to bypass and can drive the traction rope. The traction machine that leads the rope to move, the speed governor wire rope, and the two-way motor that is connected to the speed governor wire rope and can stop the car when the speed governor wire rope is c...
