Escalator with Euler handrail driving system

Abstract

The invention discloses an escalator with an Euler handrail driving system. The escalator comprises a frame body, a handrail band and a friction wheel, wherein the friction wheel is arranged in the frame body and in contact with the handrail band, the escalator further comprises two roller groups which are oppositely arranged on two sides of the friction wheel and compress the handrail band, one side is the fixed side, the other side is the regulation side, one end of the roller group positioned on the fixed side is fixed with the frame body through a fixed steel angle, the other end of the roller group is fixed with the frame body through a puller bolt, and one end of the roller group positioned on the regulation side is fixed with the frame body through a connecting steel angle; and the escalator also comprises a pull rod, one end of the pull rod is fixed with the middle part of the roller group positioned on the regulation side, the other end of the pull rod penetrates through a steel angle fixed on the frame body, an external thread is arranged on the part, which penetrates out of the steel angle, of the pull rod, and a clamping part with an internal thread is further sheathed on the part. According to the invention, the abrasion and pressure marks of the handrail band can be effectively reduced, the service life of the handrail band is prolonged, and the performances of the whole machine are greatly improved.

Description

technical field [0001] The invention relates to the field of escalators, in particular to an escalator with an Euler handrail drive system. Background technique [0002] At present, the handrail driving system of the escalator is mainly driven by multi-vedge belt pressing handrails, multi-roller belt pressing handrails, and linear pressing handrails. Almost all of the above structures use compression armrest drive system, please refer to figure 1 The compression-type handrail drive system 1' in this device has the advantage that it is easy to obtain sufficient driving force, but there are also two problems. One of the compression parts acts on the surface of the handrail, and the long-term operation will make the handrail The surface wears out rapidly and produces marks, which affect the life of the handrail; secondly, because the handrail will continue to elongate after long-term operation, the initial tension of the handrail drive cannot be guaranteed, which will cause th...

Problems solved by technology

Almost all of the above structures use compression armrest drive system, please refer to figure 1 The compression-type handrail drive system 1' in this device has the advantage that it is easy to obtain sufficient driving force, but there are also two problems. One of the compression parts acts on the surface of the handrail, and the long-term operation will make the handrail The surface is quickly worn and imprinted, which affects the life of the handrail; second, because the handrail will continue to elongate after long-term operation, the initial tension of the handrail drive cannot be guaranteed, which will cause the handrail to vibrate or slip

[0003] Theoretically, the traditional handrail drive system still has certain defects. If the adjustment is not in place and many other reasons, it is difficult to guarantee the life of the handrail, which is significantly different from the 20-year life of the whole machine.
