Problems solved by technology

The existing handrail guide device includes a plurality of fixed guide blocks arranged at intervals along the moving direction of the handrail. The guide blocks can be circular iron blocks, the center line of which is vertical The block extends into the C-shaped opening of the handrail. When the handrail moves and deviates, the circumferential surface of the circular iron block will slide in contact with the C-shaped end of the handrail. The circular iron block can prevent the deviation of the handrail. Guide the handrail belt, but the friction resistance of the sliding contact between the handrail belt and the circumferential surface of the circular iron block is relatively large. When multiple circular iron pieces are in sliding contact with the handrail belt at the same time, the resistance of the handrail belt may be greater than that of the handrail With the driving force generated by the driving device, the handrail will slip, that is, the speed of the handrail is inconsistent with the movement speed of the steps or pedals, forming a relative movement, which is likely to cause safety accidents to passengers on the escalator or sidewalk

Embodiment Construction

[0013] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] see Figure 1-3 As shown, the handrail guide device on the escalator or moving walk includes a movable handrail 1, a bracket 7 arranged on the escalator or moving walk, a guide shaft 4 arranged on the bracket 7, and a guide shaft 4 end The bearing 3 on the upper part, the cross section of the handrail 1 is C-shaped, the C-shaped opening 8 of the handrail 1 faces upward, the axis line of the bearing 3 is set up and down, and is perpendicular to the moving direction of the handrail 1. figure 1 Among them, the handrail 1 is movable horizontally, the axis line of the bearing 3 is vertically arranged, and at least part of the bearing 3 extends into the C-shaped opening 8, and the bearing 3 has a first working state and a second working state, when When the bearing 3 is in the first working state, the outer ring of the bearing 3 is in rolling contact...

Abstract

The invention discloses a hand strap guide device on an escalator or a travolater, which comprises a movable hand strap, wherein the cross section of the hand strap is in a C shape, an opening of the C shape of the hand strap is upward, and the guide device also comprises a support frame, a guide shaft and a bearing, wherein the guide shaft is arranged on the support frame, the bearing is sheathed on the end part of the guide shaft, and the axial line of the bearing is in up-down arrangement and is vertical to the moving direction of the hand strap, at least a part of the bearing extends into the opening of the C shape, the bearing is separated from the hand strap when the hand strap is moved normally, the bearing can not influence the normal movement of the hand strap, the outer ring of the bearing is in rolling contact with the tail end of the C shape of the hand strap when the hand strap deviates in the transverse direction, the bearing can guide and correct the hand strap, and in addition, the outer ring of the bearing is in rolling contact of the hand strap, so the hand strap has small friction resistance, and the slippage phenomenon of the hand strap can be avoided. Thereby, possibly occurring safety accidents can be avoided. The resistance of the hand strap is reduced through the rolling friction, the driving force requirement of the hand strap can also be reduced, the noise caused by friction can be reduced, and the service life of the hand strap can be improved.

Description

technical field [0001] The invention relates to a guide device for handrails on an escalator or moving walk. Background technique [0002] On the escalator or moving walk, the movable handrail is in the shape of a closed ring as a whole, and the cross section of the handrail is C-shaped. At this time, the handrails can be used by passengers to support them. When the handrails move to the lower part of the escalator or moving walk, there is usually no handrail guide rail to guide the handrails. In this way, the handrails may shift laterally when moving, so it is necessary to set Handrails with guides. The lower C-shaped opening of the handrail faces upwards. The existing handrail guide device includes a plurality of fixed guide blocks arranged at intervals along the moving direction of the handrail. The guide blocks can be circular iron blocks, the center line of which is vertical The block extends into the C-shaped opening of the handrail. When the handrail moves and devi...
