Liftable emergency stop interlocking device of escalator and control method of liftable emergency stop interlocking device

Abstract

The invention discloses a liftable emergency stop interlocking device of an escalator. The liftable emergency stop interlocking device comprises a brake rope, and a pull wire switch which is connected with the brake rope, wherein the pull wire switch is connected with a power control system of the escalator; the brake rope is arranged inside an automatic lifting system; the automatic lifting system comprises a group of rotary oil cylinders which are arranged below a handrail belt and used for controlling the handrail belt to start, a group of vertical lifting oil cylinders which are arranged inside a handrail protecting plate, and an automatic lifting frame which is controlled by the vertical lifting oil cylinder; the brake rope is arranged on the automatic lifting frame; a pressure sensor and a controller are arranged inside the handrail belt, wherein the controller is connected with the pressure sensor and is used for controlling the automatic lifting system to start and stop. The invention also discloses a braking method of the device. The braking method comprises the following steps: pressing the handrail belt; starting the rotary oil cylinder; starting the handrail belt; starting the vertical lifting oil cylinder; jacking the brake rope; pulling the brake rope; braking the escalator. The device disclosed by the invention can be used for conveniently and rapidly braking the escalator during the overall process and is capable of comprehensively protecting the brake rope.

Description

technical field [0001] The invention relates to an elevator brake device, in particular to an emergency stop interlock device of an escalator and a control method thereof. Background technique [0002] Existing escalators have the function of automatic lifting, although this function has brought many conveniences to people, it also brings certain potential safety hazards to users. First of all, the crawler belts of the elevator steps are constantly moving, which makes People, especially the elderly and children, tend to fall down and cause accidents when getting off the elevator; moreover, the exit of the escalator is often a place that is prone to congestion, so once blocked, the escalator will continue to transport people continuously. The collision between the people on the escalator and the blocked crowd is likely to cause safety problems; corresponding to the problem, when an accident occurs in the existing escalator, the emergency stop button is not easy to operate due...

[0002] Existing escalators have the function of automatic lifting, although this function has brought many conveniences to people, it also brings certain potential safety hazards to users. First of all, the crawler belts of the elevator steps are constantly moving, which makes People, especially the elderly and children, tend to fall down and cause accidents when getting off the elevator; moreover, the exit of the escalator is often a place that is prone to congestion, so once blocked, the escalator will continue to transport people continuously. The collision between the people on the escalator and the blocked crowd is likely to cause safety problems; corresponding to the problem, when an accident occurs in the existing escalator, the emergency stop button is not easy to operate due to its fixed position, concealment, and long distance. cause the accident to eventually occur or become more serious

[0003] The inventor of the present invention applied for two inventions on the same day, one is a combination of a tension sensor and a controller that controls the power on and off of the elevator through its electrical signal, and the other is a combination of a tension sensor and a light controller. Easy and quick braking at any time, but the brake cable is exposed for a long time, it is easy to get dirty, damaged and can be broken
