Description
Technical Field
The utility model relates to a staircase handrail area technical field, concretely relates to staircase handrail belting that anticreep rail skidded.
Background
With the rapid development of society, escalators and moving pavement equipment become essential vehicles for various large business centers and transportation hubs in cities, particularly, related accidents frequently occur in recent years and often become the focus of social attention, and part of the accidents are caused by derailment and slippage of escalator hand straps.
At present, the handrail belt of the escalator is divided into a C-shaped belt and a V-shaped belt, wherein the C-shaped belt is mainly used for a commercial ladder, and the V-shaped belt is mainly used for a public transport ladder. The main failure types of the escalator handrail are as follows: the hand strap derails and the hand strap slips. 1) The reason for derailing the handrail belt is as follows: the surface of the handrail belt in contact with the metal is too smooth and thus easily spurts out, causing derailment. At present, the inner side of the handrail belt is generally provided with a canvas layer, so that the friction force is increased, and the derailment fault is prevented. 2) The reason for the skid of the handrail belt is as follows: as above, the canvas layer is added to prevent derailment, but the increase of the friction resistance easily causes the increase of the friction resistance between the handrail belt and the guide rail, and the slip failure easily occurs.
The anti-derailment and anti-slip design of the escalator handrail in the prior art has the following problems: 1. the surface of the handrail belt in contact with metal is too smooth and easy to derail; 2. if the canvas layer is added, the friction resistance between the hand strap and the guide rail is increased easily, and the slip fault is caused.
SUMMERY OF THE UTILITY MODEL
In order to overcome the shortcoming that present handrail area derailed easily and skidded, the utility model provides an anti-derailing and skidding escalator handrail belting.
The anti-derailment and anti-slip escalator handrail belt device is realized by the following technical scheme:
the utility model provides an anticreep rail staircase handrail area device that skids is main, includes handrail area, handrail guide rail, overspeed device tensioner, gear, in the handrail area embedding rather than the guide rail that just in time agrees with, the handrail area drive wheel is the rubber gear promptly and installs the upper portion at the staircase, overspeed device tensioner installs the lower part at the staircase, the handrail area is the closed loop operation, the handrail guide rail only inclines at the passenger, the passenger side is for from A point to B point, handrail area and handrail area guide rail laminating operation, return the side for following B point to A point, the handrail area is at the inside operation of staircase, by handrail guide direction operation.
Preferably, the guide rail is V-shaped, and the protrusion of the handrail belt is just matched with the concave of the V-shaped guide rail.
Preferably, the included angle between adjacent convex teeth of the gear is 30。-90。。
Preferably, the included angle between adjacent convex teeth of the gear is 60。。
Preferably, the base material of the gear is metal, and the gear tooth part material is rubber.
Preferably, the metal material comprises steel, aluminum alloy, stainless steel and iron, and the rubber material comprises common rubber and oil-resistant rubber.
Preferably, the handrail belt is made of a rubber layer and Teflon spray coating.
Compared with the closest prior art, the utility model provides a technical scheme has following beneficial effect:
1. the handrail belt is arranged at the passenger side, and the handrail belt with the V-shaped guide rail is embedded into the guide rail, so that the derailment fault is avoided;
2. and a canvas layer in the handrail belt is eliminated, and the friction resistance is reduced by spraying a rubber layer and Teflon, so that the slip fault is effectively reduced.
