Escalator with offload guide rail abrasion detection function

Abstract

The invention discloses an escalator with an offload guide rail abrasion detection function. The escalator comprises two step chain groups operating in parallel. The two step chain groups are connected through a step shaft. Each step chain group comprises step chain roller guide rails and offload guide rails. Abrasion detection devices are arranged on the inner sides of the offload guide rails correspondingly and each comprise a connecting plate, a movable rod and a detection switch. The connecting plates are fixed to one ends of first connecting bolts correspondingly. One support arms of themovable rods are attached tightly to the connecting plates correspondingly, and grooves are formed in the other support arms of the movable rods correspondingly. The detection switches are arranged onthe connecting plates correspondingly and are further connected with an escalator control system. When the step shaft sinks and makes contact with the movable rods, the movable rods can be pushed torotate, detection portions of the detection switches can make contact with the grooves of the movable rods correspondingly, the detection switches are triggered, and signals are sent to the escalatorcontrol system. By means of the escalator with the offload guide rail abrasion detection function, the abrasion degree of the offload guide rails can be detected, it is guaranteed that the offload guide rails are replaced in time, and step chain rollers and the step chain roller guide rails are prevented from being abraded.

Description

technical field [0001] The invention relates to the field of escalators, in particular to an escalator with an unloading guide rail wear detection function. Background technique [0002] Escalators and moving walkways are widely used in people's lives. They can transfer people to the next place, which can save people's physical strength and are easy to use and shorten the passing time. Escalators are often used in places with slopes such as shopping malls, subway stations, and railway stations, while moving walkways are usually used in flat places such as airports. Due to the above advantages, escalators and moving walks are loved by everyone. [0003] For large-height escalators or moving walks, the pressure of the step chains on the guide rails is concentrated in the upper and lower transition areas, especially the upper transition area. As a result, the ladder rails in the region of the upper transition are subjected to particularly high compressive stresses. In respon...

Problems solved by technology

[0006] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to solve the problem that the unloading guide rail in the prior art does not have the function of detecting its wear, resulting in the inability to process the unloading guide rail in time, causing the step chain roller and the step chain roller guide rail to be worn To solve the problem, provide an escalator with the wear detection function of the unloading guide rail, which can detect the wear degree of the unloading guide rail and give an early warning, so as to ensure timely replacement of the unloading guide rail, and prevent the step chain roller and the step chain roller guide rail from being worn out
