Abstract
The invention relates to a truss structure of a spiral escalator. The truss structure comprises an inner supporting structure, an outer supporting structure and a web member connecting structure. Both the inner supporting structure and the outer supporting structure are an independent cylinder structure or an independent polygon structure. The web member connecting structure is a connecting structure for connecting the inner supporting structure with the outer supporting structure. The truss structure of the spiral escalator is a closed structure, and needs not to be supported by a building structure; since the mechanics of the closed structure of the truss of the spiral escalator is optimized, a large amount of materials can be saved, and the truss structure is high in economic superiority; and the cylinder structure is a supporting structure per se, so that the truss of the spiral escalator adopts the closed structure and can be used as a support for a building roof.
Description
Technical field
The present invention relates to the truss-frame structure of a kind of escalator, particularly relate to the truss-frame structure of a kind of spiral escalator.
Background technology
Escalator is a kind of public transport driving step (being called for short ladder chain) to run by desired trajectory guide rail (being called for short ladder road) by transmission chain, is mainly used in stream of people's comparatively dense public place at different levels layer conveying people and a small amount of goods. Traditional line staircase affects due to self gravitation, promotes field in superelevation and there is many drawbacks, especially the public transport escalator of lift height more than more than 12 meters, and the truss supporting escalator needs to add multiple point of suppon halfway. There is synergistic effect and parallelogram effect due to chain drive simultaneously, the two acting in conjunction adds superelevation and promotes the frictional dissipation between escalator chain and guide rail, too increase power system and transmission system abrasion, during this series products of domestic manufacture, still have certain difficulty.
The truss of escalator needs to be fixed on floor, by building as escalator provides support. From side direction, the horizontal structure of moving staircase girders mainly comprises flat layer segment, lower flat layer segment and the middle connection structure running section part three part and three; From longitudinally, moving staircase girders is longitudinally primarily of two, left and right lamella and the web member composition connecting them, and left and right lamella is substantially completely identical; Sometimes web member itself composition lamella, web member lamella can be divided into lower flat layer segment equally, upper flat layer segment and operation part three part.
Spiral escalator is the novel Lifting Convey equipment of relatively existing straight line escalator; Especially promote field spiral escalator in superelevation and have obvious technology and economic advantages especially. Spiral escalator is due to itself constructional feature, self can be placed in a cylindrical space, intermediate strut problem can conveniently solve, this has just greatly expanded scope for the application of escalator, utilizes spiral this kind of characteristics design the truss of independent support spiral escalator to be the object of the present invention.
Retrieve according in CPRS and EPODOC two system, the result for retrieval that is the theme by IPC:B66B21/06 of spiral escalator was 12 and 114 (comprising of the same clan), staircase and girder IPC:B66B23/00, merging retrieval two classification number results is zero, it is seen that the research in relevant field is tangible too rare. Terraced road related to the present invention, ladder chain, drives, automatically controlled, and all systems of safety are by separate case application.
Summary of the invention
The present invention is intended to solve the truss-frame structure problem of spiral escalator, thus make spiral escalator as a kind of can the escalator of independent support own wt, without the need to building, spiral escalator is provided support, it is even possible that spiral moving staircase girders is as the support structure built. According to the model formation of equal lead right helicoid and equal lead duplex, the vibrations that spiral moving staircase girders not only to be undertaken original ladder chain gravity burden in the vertical direction and produce with rail friction at the roller that guiderail track is tangential, to be solved the support that the up time tangential force of spiral motion is born simultaneously. Truss in existing successful spiral escalator design is except to be overcome spiral escalator ladder chain instantaneous vibration and for except power system support structure, front and back sequence of operation relation according to chain side bend and the centripetal force requirement of instantaneous close plane, spiral moving staircase girders needs to provide support to offset too much chain centripetal for it inside ladder chain, in any case but side bow roller chain closed-ended question determine spiral escalator 180 ° turn to the limit.
The design that the present invention proposes based on duplex escalator and variable topological transmission rig (related invention separate case application), ladder chain forms variable topological transmission rig by step and chain link combined action, ladder chain is overall forms the positive spiral statically determinate structure of equal lead under track half dimension restriction effect, the truss of spiral escalator not only needs the radial centripetal reactive force offsetting chain in inner side at this moment, need in outside to provide radial centripetal reactive force simultaneously, thus form the centripetal reactive force of ladder chain spiral motion osculation plane. So the track support bar that first spiral moving staircase girders involved in the present invention needs and motion track is consistent gives spiral drive chain of escalator bar to support in whole process, truss is needed to need to determine that grid is with the fixing support for track support bar afterwards; So giving the stepping motion feature of spiral escalator, spiral escalator needs both sides inside and outside step radial direction to provide the truss closed to meet corresponding kinetics requirement physical construction.
The design original intention of spiral moving staircase girders is spiral escalator step sequence and step roller track and power system, Controlling System and safety braking system provide the supporting structure laid, relative to other truss, especially the steel construction of building field, spiral moving staircase girders positioning precision and error requirements are all higher, need due to escalator the building elasticity distortion overcoming for the impact of guide rail simultaneously, also need to meet the problem of escalator needs scheduled maintenance simultaneously; So spiral moving staircase girders is using vertical vertical rod as Gravity support element, with horizontal cross bar centripetal-stress support component the most; Interior laminated structure and outer plies structure all form stable support with closed structure, finally act on the positive spiral guide rail of equal lead of spiral escalator, it is provided that step run required for Gravity support and turn to required centripetal force.
The technical program designs based on the spiral escalator of a more than helical pitch completing, if when the stroke that spiral escalator completes is less than a helical pitch, spiral moving staircase girders can according to the concrete stroke of spiral escalator and track minimizing material and structure, as being just that whole truss and escalator provide support by interior laminated structure or outer plies structure, between interior outer plies, do not use web member connection etc.
The main useful effect of the technical program is tradition moving staircase girders knot relatively, and spiral escalator involved by the application is closed structure, it is not necessary to building structure is provided support;Closing theory of structures due to spiral moving staircase girders to be optimized, materials of can saving in a large number, have comparatively superior economic advantages; Due to column structure inherently a kind of supporting structure, thus spiral escalator involved by the application be closed structure can as the support of the building height of a house.
