Problems solved by technology

[0005] According to the search in the CPRS and EPODOC systems, the search results for the spiral escalator as IPC: B66B21 / 06 are 12 and 114 (including the same family), the escalator truss IPC: B66B23 / 00, and the combined search results for the two classification codes are zero, which can be seen Research in related fields is too rare

Embodiment 1

[0017] Embodiment 1, radial projection mapping structural scheme: the inner structure and the outer structure are in a projection relationship, and the webs are arranged in a radial direction. The advantage is that it is easy to manufacture. Wherein the columns of the inner structure, the crossbeams, and the diagonal stays all have the same parts, and the same columns, crossbeams and diagonal stays are found on the outer structure. Wherein the crossbeam is a horizontal connecting rod, and the diagonal stay rod is the track or track projection of the spiral escalator.

Embodiment 2

[0018] Embodiment 2, non-radial projection mapping structure scheme: the inner layer structure and the outer layer structure are in a non-projective relationship, and the webs are not arranged in a radial direction. Although the process is complicated and the production is cumbersome, the advantage is that the structure is firm. Among them, the columns, beams, and diagonal stays of the inner structure have the same components. The same columns, beams, and diagonal stays are found on the outer structure, but the components at different levels are not arranged according to the radial projection relationship. Among them, the horizontal connecting rod of the beam and the diagonal stay rod are the trajectory or trajectory projection of the spiral escalator.

[0019] This technical solution is designed on the basis of a spiral escalator that can complete more than one lead. If the stroke completed by the spiral escalator is less than one lead, the spiral escalator truss can reduce th...

Abstract

The invention relates to a truss structure of a spiral escalator, comprising an inner support structure, an outer support structure and a web connection structure, the inner support structure and the outer support structure are independent cylindrical structures or polygonal structures, The web connection structure is a connection structure between the inner support structure and the outer support structure. The truss structure of the spiral escalator is a closed structure, which does not need to be supported by the building structure; because the mechanics of the closed structure of the spiral escalator truss is optimized, it can save a lot of materials and has a relatively superior economic advantage; because the cylindrical structure itself is a A support structure, so the spiral escalator involved in this application is a closed structure and can be used as a support for building lifting frames.

Description

technical field [0001] The invention relates to a truss structure of an escalator, in particular to a truss structure of a spiral escalator. Background technique [0002] The escalator is a public transportation tool that drives the steps (referred to as the ladder chain) according to the predetermined track guide rail (referred to as the ladder road) by the transmission chain. It is mainly used in public places with dense crowds to transport people and a small amount of goods at different levels. Due to the influence of its own gravity, traditional linear escalators have many disadvantages in the field of ultra-high lifting, especially for public transportation escalators with a lifting height of more than 12 meters. The truss supporting the escalator needs to add multiple support points midway. At the same time, due to the superposition effect and parallelogram effect of the chain drive, the combined effect of the two increases the friction loss between the chain and the g...
