Description
Technical field
The present invention relates to a kind of separate stair structure of escalator, belong to stair structure designing technique and staircase and make the field.
Background technology
Step is the functional component that escalator transports the passenger.It is as lorry, drags down in the traction of traction chain, does the operation of closed loop track along its terraced guide rail system.Assembled stair structure from its formation and function distinguishing, mainly comprises pedal assembly and skeleton structure two parts.Pedal assembly is installed on the skeleton structure, only stand for the passenger and trample the usefulness of holding, and passenger's gravity loading and traction drags load, are then born by the skeleton structure of its underpart fully.So the frame mode of skeleton, mechanical property, and the geometrical stability of structure is the core technology of its structure design.
Structurally there are some defectives in existing step skeleton, mainly show as: 1. the cross section is the strip front cross rail of " Г " shape, be installed in overhanging hang on the vertical plane of two triangle support front ends, it is with respect to two triangle supports, not only do not have vertical each other location and installation benchmark, very little being difficult to of retaining carpenters square of opening of its high and low position and two triangle supports accurately determined.And only depend on the angle-shaped piece that is located at two ends between them and use the screw transition to connect, so linking intensity is poor.Simultaneously, front cross rail top attachment face is narrow strip, only accounts for 1/2 of the preceding reinforcement width of pedal, so supporting connection performance is obviously not good.2. A-frame top-supported locating surface is and how step-likely is uneven, and is welded with an additional angle-shaped piece at this face.For guaranteeing the tread horizontality, so set its height dimension difference of three reinforcements in tread bottom remedies the diff-H that each associated components assembling back forms at the supporting locating surface with this.This frame mode, not only manufacturing process is numerous and diverse, the cost height, and the height dimension between many steps is difficult for guaranteeing.Simultaneously, the reinforcement of differing heights size, interchangeability is poor, brings new trouble to manufacturing again.3. the entablatrance on the kickplate assembly, its mounting support portion is a plane.The big span supporting structure in this sheet steel plane obviously can not be enough to bear the passenger's gravity loading from the pedal tread.Although the circular arc face of weld that is provided with a bending and forming at this surface rear end is taken into account strengthened, should in face of bearing value of end obviously not enough, thereby directly influence the load-carrying capacity and the stability of skeleton structure.
Summary of the invention
The objective of the invention is to solve the defective that prior art exists, provide a kind of structural behaviour stable, overload capacity is big, and is rational in infrastructure, easy to assembly, the simple separate stair structure of escalator of manufacturing process.
For this reason, the present invention adopts following technical scheme:
Separate stair structure of escalator comprises: two parallel and symmetrically arranged A-frames, be loaded on the front cross rail of two triangle support front positions, be loaded on the kickplate assembly of two triangle back-end supports, the lower and upper cross-member correspondence on the kickplate assembly is installed in the upper and lower of two triangle back-end supports.Be loaded on the main shaft wheel seat of two triangle support forward positions, be loaded on the jockey pulley seat of two triangle back-end support bottoms.
Front cross rail is placed two triangle support front end rigging positions, level and vertical installing and locating face that its two ends are provided with, contact the location with two triangle support top-supported attachment faces with the inboard, upright attachment face respectively, and pass the via hole of two member vertical surface with screw, directly be screwed in the screw of main shaft wheel seat, its three are fixedly connected.Another screw then is fixedly connected two levels contact locating surface.In order to strengthen connection, vertically strengthen being respectively equipped with angle-shaped piece, and realizing that with screw its transition connects between face two ends and A-frame medial shaft face directly at front cross rail.Lower and upper cross-member correspondence on the kickplate assembly is installed in the upper and lower of two triangle back-end supports.The kickplate assembly is to be the assembly that one forms with lower and upper cross-member and kickplate through multipoint positioning spot welding, its horizontal mounting surface of entablatrance contacts with two triangle support top-supported attachment face rear portions in the mode of being affiliated to, and by assembly technology equipment guarantee its with respect to before and after the two triangle supports and about the location, with screw it is connected firmly on two triangle support top-supported attachment faces.The contact of the corresponding inclined-plane of its inclination attachment face of cross sill with two triangle supports, and pass the via hole on two member inclined-planes with screw, directly be screwed in the screw of jockey pulley seat side, its three are fixedly connected.In order to strengthen connection, the medial shaft of two triangle back-end support bottoms face directly and cross sill two ends inclination attachment face between, be respectively equipped with angle-shaped piece, and realize that with screw its transition connects.
Technical scheme of the present invention compared with prior art has following advantage:
1, the front cross rail two ends are equipped with level and vertical two kinds of installing and locating faces, can effectively determine the rigging position relation of this part with respect to two triangle supports simultaneously fast.Make parallel between them, vertical, and two be arranged that precision is guaranteed simultaneously in the internal arm span of A-frame and front cross rail and its symmetry branch in parallel.So rational in infrastructure, easy to assembly, work efficiency improves.
2, the horizontal mounting support face on the front cross rail, its width and length and pedal reinforcement attachment face adapt, and the strip that is provided with evagination at this face is along its length strengthened the ridge, simultaneously, parallel again bending after being provided with perpendicular bending below this face, and " L " shape identical combination reinforcement face with beam body length direction.Then the mounting support face that adapts with pedal reinforcement attachment face specification can make the two sides all accord with real contact, has avoided half contact, half unsettled un-reasonable phenomenon.And, the enforcement of multinomial enhancements, to the structural stability of effective raising front cross rail itself and even whole skeleton, load-carrying capacity all has positive effect.
3, front cross rail with the mounting structure mode of two triangle supports is: vertical each other installing and locating face is set up at the front cross rail two ends separately, respectively with two triangle support top-supported attachment faces and inboard, upright attachment face location and installation, so be " built-in " formula, non-" overhanging suspension " formula.This mounting structure mode, compact conformation not only, each member stress is reasonable, connects reliable and stablely, and can further improve structural stability.
4, A-frame top-supported attachment face is a plane, and welds a little sheet steel at this millet cake.Such structure treatment mode, avoided A-frame top-supported attachment face many places to be uneven on the one hand, with the uppity defective workmanship of diff-H size, and then avoided this unreal again, the fault of construction of irregular cavitation occurred in the face of the pedal assembly supporting.Removed that special angle-shaped piece is made from and with the required raw MAT'L of A-frame assembly welding and the artificial wasting of resources.Simultaneously, the so simple structure treatment mode of A-frame top-supported attachment face makes three its scantling of structure of reinforcement on the pedal assembly can be in full accord, so it has interchangeability.Avoided in the prior art reinforcement structure size different, and do not had interchangeability and bring many troubles and waste to production.Thereby for pedal assembly provides a kind of failure-free supporting basis.
Entablatrance on the kickplate assembly is characterized in that: at its horizontal mounting surface width end, and along its length, be provided with vertical with this face and the reinforcement of bending up face.At the step confined state, this face stretches in the groove of pedal assembly rear end reinforcement.The setting of this reinforcement face not only can effectively improve its horizontal mounting surface and bear non-deformability under passenger's gravity loading state, also helps to improve simultaneously the structural stability of step skeleton rear end.
