Description
Technical Field
The utility model relates to the technical field of escalators, in particular to a combined handrail guide rail which is mainly applied to escalators and moving sidewalks.
Background
In the prior art, the frictional resistance of a handrail system of an escalator or a moving sidewalk mainly comprises two parts: the resistance of the bending section can be theoretically evaluated through a flexible friction Euler formula; the friction resistance of the straight line segment can be theoretically calculated according to the positive pressure and the friction coefficient acting on the handrail guide rail, and finally the positive pressure and the friction coefficient are combined. The coefficient of friction directly affects the frictional resistance in a handrail system, whether for curved or straight segments. For an escalator or a moving sidewalk, a handrail belt is generally driven by friction wheels in the running process, the handrail belt can circularly move mainly by relying on the driving force of the friction wheels to overcome the friction resistance in the whole circular movement, when the resistance is overlarge, the handrail belt can slip, and when a passenger holds the handrail belt, the handrail belt can be unstable, so that the falling phenomenon is caused.
When the handrail belt circularly moves, the handrail belt is in frictional contact with the handrail guide rail, the handrail belt circularly moves, the handrail guide rail is still, and the handrail belt is directly contacted with the top of the handrail guide rail under the action of gravity and handrail tension in a straight section or an upper bending section of the escalator or the moving sidewalk. For the escalator with a large lifting height, in the upper bending section, the handrail belt is tightly pressed on the upper surface of the handrail guide rail under the action of tension, so that the handrail belt is seriously abraded, and if the handrail belt is not replaced in time, the handrail belt can be separated from the handrail guide rail, and potential safety hazards are caused. But would add significant cost if the entire handrail guide were replaced.
