The Structure and Main Parameters of Escalator-2

(8) Handrail drive: As shown in Figure 6.9, driven by the drive device directly through the armrest drive chain, without the middle shaft, armrest drive wheel with oil-resistant rubber friction layer, with its high friction to ensure that the handrail with the steps Run synchronously.

     In order to obtain sufficient friction force for the handrail belt, a pulley group is provided under the armrest drive wheel. The tension of the belt is adjusted by a spring and screw in the pulley to ensure that the handrail is working properly.
(9) Handrails: Handrails are made of a variety of materials, mainly natural (or synthetic) rubber, cotton fabric (cord fabric) and steel wire or strip. Handrail with the standard color is black, according to customer requirements, according to the handrail with a color card to provide a variety of colors of the handrail (mostly synthetic rubber). The quality of handrails, such as physical properties, appearance quality, packaging and transportation, must strictly follow the relevant technical requirements and specifications.
 
 
(10) Comb Teeth, Comb Plate, Floor Board:  Conai Comb Plate Specification and Information
   ① comb teeth: in the escalator entrance should be installed comb teeth and comb plate to ensure the safety of passengers transition. The cogs on the comb should engage the cogs on the steps, and even if the passenger's shoes or items are relatively stationary on the steps, they will smoothly transition to the floorboard. Once an item hinders the run of the runner, the comb is lifted or displaced, allowing the escalator to stop running. Comb teeth can be used aluminum die casting, plastic injection molding can also be used.
    ② comb plate: comb plate to fix the comb teeth. It can be made of aluminum alloy profiles, can also be made of thick carbon steel plate.
    ③ floor board (landing board): floor board is the escalator passengers out of the population, but also on the platform, the next platform maintenance room (room) cover, generally made of thin steel, the back of the welding with ribs. Floor plate surface should be equipped with wear-resistant, non-slip materials, such as aluminum alloy profiles, pattern stainless steel or rubber flooring.
    (11) Balustrade: The balustrade is located on both sides of the cascade and functions as a protective and decorative (Figure 6.12). It has a variety of types, structure and materials are not the same, generally divided into vertical rail and tilt the balustrade. These two types of handrails can be divided into full transparent without support, full transparent support, translucent and opaque 4 kinds. Vertical balustrade for the whole transparent unsupported balustrade, tilt the balustrade for the opaque or translucent balustrade. As the balustrade structure is different, handrail belt drive also will be different.
 Vertical Balustrade: This type of handrail with self-supporting safety glass liner.
② Tilt Balustrade: This handrail with stainless steel liner. The liner is arranged in a sloping manner with the step. Generally used to enhance the height of the escalator, because the weight of the larger handrails, glass can not be used as a support, but also in the handrail with a turning point to increase the steering wheel.
    (12) Lubrication system: all the cascade chain and the steps of the roller are permanent lubrication. The main drive chain, the armrest drive chain and the cascade chain are lubricated separately by the automatic control lubrication system. The lubrication system for the automatic timing, fixed point directly to the lubricating oil spray pin, so that it is a good lubrication. Lubrication system in the pump or solenoid valve start-up time, oiling time by the control cabinet in the delay relay control (PC control by the PC internal time relay control).
    (13) Safety devices: escalators are an important tool for public transport, safety is essential. With the application of PC, automatic alarm failure, automatic display, automatic fault analysis can be achieved. According to the escalator safety standard (EN) regulations, escalators must have the following 15 kinds of safety devices:
   ① broken chain (cascade chain) emergency stop switch.
   ② stop with (handrail) emergency stop switch.
   ③ cascade level monitoring device.
   ④ over-current protection, phase monitoring.
   ⑤ handrail population contacts.
   ⑥ comb tooth contact.
   ⑦ guardrail apron contacts.
   ⑧ drive shaft safety brake.
   ⑨ floor floor safety contacts.
   ⑩ the gap of the ladder lighting.
   ⑩ emergency switch.
   ⑩ door interlock device.
   ⑩ electrical anti-reversing device.
   ⑩ anti-step lift track.
   ⑩ escalator smoke detectors and so on.
