Fixing device for escalator handrail belt lining layer

Abstract

The invention discloses a fixing device for an escalator handrail belt lining layer, and relates to the technical field of urban rail engineering. The fixing device comprises a bottom frame, a sliding base is fixed to the side face of the bottom frame, two symmetrically-distributed pressing parts are movably connected to one side of the sliding base, and the two pressing parts rotate in the opposite directions; a mounting base is further fixed to the side face of the bottom frame and provided with a cylinder, and the cylinder is located on the inner sides of the two pressing parts; and a groove body is formed in the cylinder, and a first pin roller, a second pin roller, a third pin roller and a rotating roller set are rotationally arranged in the groove body, Wherein, one end of the cylinder is attached to the outer side of the first pin roller through a lining layer of the rotating roller set, the other end of the cylinder is attached to the outer side of the second pin roller through a tensile wire harness of the rotating roller set, and a box body communicating with the third pin roller is fixed to the outer side of the cylinder. By means of the pressing parts arranged on one side of the cylinder, part of the inner surface of an escalator handrail belt is tightly attached to the peripheral side face of the cylinder and adheres to an anti-stretching assembly.

Description

technical field [0001] The invention belongs to the technical field of urban rail engineering, and in particular relates to a fixing device for an inner liner of an electric escalator handrail. Background technique [0002] Escalator, also known as escalator, or automatic pedestrian elevator, escalator, etc., is a means of transportation that transports pedestrians in the form of a conveyor belt. Escalators are generally inclined. Pedestrians stand on the self-propelled steps at one end of the escalator, and they will be automatically taken to the other end of the escalator, and the steps will be kept level all the way. The escalator has handrails on both sides that move synchronously with the steps for users to hold on to. [0003] When the escalator is in use, there are mainly two moving parts, one is the inclined upward movement of the steps, and the other is the friction transmission of the escalator handrail. Escalator handrails are easily deformed during long-term f...

Problems solved by technology

[0004] The object of the present invention is to provide a fixing device for the inner lining of the handrail of an electric escalator. The part of the inner surface of the handrail of the electric escalator is closely attached to the peripheral side of the cylinder through the pressing part installed on one side of the cylinder and bonded to resist tension. The extension component solves the problem of poor stretch resistance of the existing handrails of escalators
