Description

A step chain assembly for escalator

technical field

The invention belongs to the field of escalator technical equipment, and in particular relates to a step chain assembly for escalators.

Background technique

The escalator is composed of a chain conveyor with a special structure and two belt conveyors with a special structure, with a cyclic movement ladder, which is used to go up or down between different storeys of the building. Fixed electric drive equipment for inclined transport of passengers, can be widely used in stations, docks, shopping malls, airports and subways and other places where people are concentrated. The main component that plays the role of transmission in the escalator is the step chain assembly. The step chain assembly plays an important role in the operation of the escalator. Because of the step chain and gear transmission, in order to maintain the stability of the escalator, escalators on both sides are required. The operation is synchronized, and the existing escalators are mostly driven by a single chain, resulting in insufficient stability of the escalator.

In order to solve the above problems, the present invention provides a step chain assembly for escalators. The step chain assembly for escalators adopts the step chain group to drive the operation of the escalator, which can enhance the stability of the operation of the escalator.

In order to achieve the above object, the present invention is achieved through the following technical solutions: a step chain assembly for escalators, comprising a pair of step chains and a set of step shafts, the step shafts are evenly arranged between the pair of step chains, and the The step chain includes a group of inner chain pieces, a group of outer chain pieces and a group of roller parts, the inner chain pieces and the outer chain pieces are sequentially staggered and connected, the inner chain piece is arranged inside the outer chain piece, and the inner chain piece is arranged on the inner side of the outer chain piece. The parts connected with the outer chain pieces are all provided with roller parts, the roller parts are connected with the inner chain pieces and the outer chain pieces by pins, and the ends of the pins are fixed with snap rings. Connecting a pair of step chains through the step shaft can make the step chains on both sides of the escalator run synchronously and maintain the stability of the escalator.

Further, two sets of roller parts are arranged between the adjacent step shafts. The longer the interval between the step shafts will affect the stability of the step chains; the shorter the interval between the step chains, the more complicated the structure of the step chain group will be.

Further, the roller component includes a roller, the roller is sleeved on the outer side of the pin, and a bearing is provided between the roller and the pin. Bearings reduce friction between the rollers and the pins, allowing the rollers to rotate along the gears.

Further, an oil filling port is provided on the roller, and the oil filling port is arranged near the inner chain piece. It is convenient to add lubricating oil at the oil filling port, which can make the roller run more smoothly and increase the smoothness of the escalator.

Further, a sealing ring is provided in the roller near the oil filling port, and the sealing ring is sleeved on the outer side of the pin. Enhances the sealing performance of the lubricating oil injected into the roller.

Further, the pin outer sleeve is provided with a bushing, and the axle bushing is sleeved on the inner side of the inner chain piece and the roller. Bushings enhance the connection of the rollers to the pins.

Further, the roller jacket is provided with a non-slip layer. It can prevent the movement between the roller and the gear, and enhance the anti-skid performance of the roller.

Further, the anti-skid layer is made of polyurethane rubber material. Polyurethane rubber material has high hardness, good strength, high elasticity, high wear resistance, aging resistance, and also has cushioning and shock absorption.

Beneficial effects: Compared with the prior art, the present invention has the following advantages: a step chain assembly for escalators provided by the present invention, the step chain assembly for escalators connects a pair of step chains through a step shaft, The step chain on both sides of the escalator can run synchronously to maintain the stability of the escalator. The roller parts are driven with the transmission gear to drive the operation of the escalator. It is convenient to add lubricating oil at the oil filling port, which can make the operation of the rollers smoother and increase the smoothness of the escalator. The anti-skid layer can prevent the movement between the roller and the gear, and enhance the anti-skid performance of the roller.
