Embodiment Construction

[0013] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.

[0014] Such as figure 1 As shown, the car-type elevator with single guide rail and double anti-falling includes two vertical beams 2 arranged on opposite sides of the elevator car 1; 3 and a constant motion component 4, wherein the constant motion component 4 is connected to the control device of the elevator car 1 through a sliding motor 7, thereby ensuring that the constant motion component 4 is transported up and down with the elevator car 1 at the same time, and the constant motion component 4 is arranged on the elevator The bottom of the car 1, and it is in contact with the elevator car 1 through a telescopic pillar 5; a displacement sensor 6 is also provided at the conne...

Abstract

The invention discloses a single-guiderail double-falling prevention lift car elevator which comprises two vertical beams disposed on two opposite sides of an elevator car, wherein each vertical beam has a slide rail form and is sleeved by a constantly fixed assembly and a constantly movable assembly, the constantly movable assembly is connected to a control device of the elevator car by a sliding motor, and the constantly movable assembly is disposed on the bottom of the elevator car and gets contacted with the elevator car by an extensible strut; a displacement sensor is also disposed at a joint between the extensible strut and the elevator car; and the constantly fixed assembly is disposed on the bottom of stairs of a building and comprises an emergency control device, an emergency motor and a sliding frame body, and the displacement sensor is electrically connected to the emergency control device of the constantly fixed assembly. The single-guiderail double-falling prevention lift car elevator disclosed by the invention has the advantages that the lift car elevator can make an emergency response more quickly when the elevator slides down; and an anti-falling device can be started in time to support the elevator car, so that safety performance of the lift car elevator can be enhanced.

Description

technical field [0001] The invention relates to the technical field of car-type elevator fall prevention, in particular to a car-type elevator with single guide rail and double fall prevention. Background technique [0002] Existing car-type elevators, anti-falling devices, in terms of hardware, speed limiters, safety gear, buffers, end station protection devices and the like. The speed limiter can reflect the actual running speed of the elevator. When the speed of the elevator exceeds the allowable value, it can send out electrical signals and generate mechanical actions to cut off the safety circuit or force the safety gear to act. It is installed in the machine room. The safety gear can be linked with the speed limiter to force the car to stop on the guide rail by mechanical action, and is installed on both sides of the car or counterweight. The buffer absorbs energy when the car or the counterweight hits the bottom pit to ensure the safe braking of the car. There are sp...
