Embodiment Construction

[0010] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] see Figure 1-2 As shown, the driving device of the handrail on the escalator or the moving walk includes a wheel shaft rod 8 arranged horizontally on the truss 7 of the escalator or the moving walkway, a friction wheel 1 set on the inner end of the wheel shaft rod 8, and a wheel shaft rod set on the wheel shaft rod. 8 The drive sprocket 3 at the outer end, the drive chain 4 surrounding the drive sprocket 3 and used to drive the drive sprocket 3 to rotate, the drive sprocket 5 connected to the drive sprocket 3 through the drive chain 4, the drive chain The wheel 5 is indirectly driven by the motor to rotate, and the drive chain wheel 3 is driven to rotate by the transmission chain 4, then the friction wheel 1 rotates, and the handrail 2 surrounds the friction wheel 1. After the friction wheel 1 rotates, the friction wheel 1 gives the handrail be...

Abstract

The invention discloses a driving device of a hand strap on an escalator or a moving pavement, comprising an axle rod, a friction wheel, a drive sprocket and a drive chain, wherein the axle rod is horizontally arranged on a truss of the escalator or the moving pavement; the friction wheel is sleeved at one end of the axle rod; the drive sprocket is sleeved at the other end of the axle rod; the drive chain is wound on the drive sprocket and is used for driving the drive sprocket to rotate; the hand strap goes around the friction wheel; the friction wheel is arranged inside the truss; and the drive sprocket and the drive chain are arranged outside the truss. Compared with the background art, the invention can narrow the width direction of the truss, realizes smaller size design and reduces the occupied sap space of the escalator or the moving pavement and cost.

Description

technical field [0001] The present invention relates to a drive device for handrails on escalators or moving walks. Background technique [0002] On the escalator or moving walk, the existing driving device of the handrail can refer to the Chinese patent document "Handrail Driving Device at Rotary End", publication number CN101224843A, published on July 23, 2008. In this patent document, the driving of the handrail The device includes a rotary sprocket shaft, a handrail drive shaft, a handrail drive sprocket set on the rotary sprocket shaft, a handrail drive sprocket set on the handrail drive shaft, a drive chain wound on the handrail drive sprocket, and the handrail drive sprocket, The handrail drive wheel is arranged on the handrail drive shaft. The handrail drive wheel is used to drive the handrail belt to move. The driving device of the handrail belt is integrally installed in the truss of the escalator or moving walk, which results in a larger size in the width directio...
