Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

The embodiment of the application provides an escalator or a moving sidewalk, which is used for automatically conveying pedestrians between two fixedly arranged places so as to overcome complex terrain obstacles, avoid the pedestrians from walking and reduce physical loss of the pedestrians.

The escalator is a fixed electric driving device which is formed by combining a chain conveyor with a special structure form and two belt conveyors with a special structure form, is provided with a circulating movement ladder way and is used for conveying passengers upwards or downwards at different story heights of a building. Specifically, it may be a continuous transport machine having a walk-substituting property in which a carrier moves up and down. The escalator consists of a ladder way and handrails at two sides. The main components of the device comprise steps, a traction chain and a chain wheel, a guide rail system, a main transmission system (comprising a motor, a speed reducer, a brake, an intermediate transmission link and the like), a driving main shaft, a ladder way tensioning device, a handrail system, a comb plate, a ladder framework, an electric system and the like. The stairs horizontally move at the entrance of the passenger so as to facilitate the passenger to climb the stairs and gradually form the stairs later; the steps disappear gradually near the exit and the steps 50 move horizontally again to facilitate the passengers getting off the stairs.

The moving walkway, in turn, refers to a fixed electrically driven installation with a circulating (plate or belt) walkway for transporting passengers with a horizontal or inclined angle not greater than 12 °. The structure of the escalator is similar to that of an escalator and mainly comprises a moving pavement and a handrail. The moving sidewalk is suitable for places with concentrated pedestrian streams, such as stations, docks, shopping malls, airports, exhibition halls, sports halls and the like. The step-like shape is not formed even when the movable road surface is inclined.

The main bearing framework of the automatic sidewalk or the escalator is the truss 300. As will be readily appreciated, the truss 300 is typically a steel frame structure formed by welding or assembling steel members for installation in a construction site to carry a main drive system, a track system, etc.

For some large span applications, the length of the truss 300 may need to be designed to be correspondingly long. However, due to the limitations of installation and transportation, the steel members constituting the truss 300 cannot be made into a long whole, and thus a sectional design is required. The original integral truss 300 is manufactured into the segmented truss with shorter length and smaller volume and the corresponding connection structure 200, and the segmented truss is assembled and connected into the integral truss by means of the connection structure 200, so that the use requirement is met, meanwhile, the assembly and connection are convenient, and the structural strength is high.

As shown in fig. 1, fig. 2, fig. 4 and fig. 5, a schematic structural diagram of a connection structure 200 equipped in a truss 300 for applying the connection structure 200 according to an embodiment of the present application is shown, where the connection structure 200 includes: a first docking member 10, a second docking member 20, a first connecting assembly 30 and a second connecting assembly 40.

The first and second docking members 10 and 20 each include a beam 50, a first docking plate 60, and a second docking plate 70; the first connection plate 60 is welded and fixed on the upper portion of the beam frame 50, the first connection member 10 and the second connection member 20 are further provided with first assembly holes 61 penetrating through the first connection plate 60 and the beam frame 50, and the first connection assembly 30 is inserted and fixed in two adjacent first assembly holes 61; and a second connection plate 70 is welded and fixed at the bottom of the beam frame 50, the first connection member 10 and the second connection member 20 are also provided with second assembly holes 72 which penetrate through the second connection plate 70 and the beam frame 50, and the second connection assembly 40 is inserted and fixed in two adjacent second assembly holes 72.

The implementation of the technical scheme of the embodiment has the following beneficial effects: the connection structure 200 of the above scheme is applied to a truss 300 structure of an escalator or a moving sidewalk, and is specifically used for assembling and connecting two adjacent segmented trusses (i.e., a first segmented truss and a second segmented truss), so that the number of machining processes is reduced, the machining efficiency is improved, and the labor intensity of workers is reduced. Specifically, during production, the first connector plate 60 may be welded and fixed to the upper portion of the beam frame 50 in a factory, and the first assembly holes 61 may be integrally drilled in the first connector plate 60 and the beam frame 50; meanwhile, welding and fixing a second connection plate 70 to the bottom of the beam frame 50, and drilling second assembly holes 72 on the second connection plate 70 and the beam frame 50 respectively; the first and second docking members 10 and 20, which are substantially or exactly the same in structure, have been obtained; then, the first connection member 10 and the second connection member 20 are transported to a construction site, the first connection member 10 is fixedly installed at the end of the first segmental truss, the second connection member 20 is fixedly installed at the end of the second segmental truss, and at the moment, the first connection member 10 and the second connection member 20 are adjacently and oppositely arranged at the connection position of the first segmental truss and the second segmental truss; finally, the first connecting assembly 30 is inserted and fixed into two adjacent first assembling holes 61, and the second connecting assembly 40 is inserted and fixed into two adjacent second assembling holes 72, so that the assembly of the first connection member 10 and the second connection member 20 can be completed quickly, and the first sectional truss and the second sectional truss can be assembled into a whole finally. Compared with the traditional connection structure 200, the first connection plate 60 and the second connection plate 70 can be integrally machined and fixed on the beam frame 50 in advance in the scheme and are integrally perforated, necessary enough structural strength can be obtained, the number of the perforated holes is small, the hole perforating operation is not needed on site, the assembling process and the steps are simple, the machining period is short, the labor intensity of workers is low, and the production and machining efficiency is improved.

Referring to fig. 1, for convenience of description and understanding of the present invention, the truss 300 is divided into two parts, i.e. the truss 300 includes a first part truss and a second part truss. The first and second segmented trusses each include an upper chord 310 and a lower chord 320, and the upper chord 310 and the lower chord 320 are arranged side by side at intervals in the height direction. Specifically, the upper chord 310 and the lower chord 320 may be steel structural members such as angle steels and channel steels, and the materials are convenient to obtain, and have good applicability and implementation.

In order to obtain higher overall structural strength of the truss 300, a plurality of web chords arranged vertically or obliquely are further connected between the upper chord 310 and the lower chord 320. Alternatively, the web may be welded, bolted, or riveted to the upper and lower chords 310, 320; the concrete selection can be carried out according to the actual requirement.

It should be noted that the first connection plate 60 should be welded to the upper chord 310 in a welting manner, and the second connection plate 70 should be welded to the lower chord 320 in a welting manner, so as to facilitate accurate positioning when the connection structure 200 is assembled with the upper chord 310 and the lower chord 320.

It is easy to understand that the first connection member 10 and the second connection member 20 adopt a symmetrical structure design, so as to facilitate reducing the manufacturing cost and difficulty and improving the production efficiency.

As shown in fig. 7, the present application also provides a method for manufacturing the docking structure 200, which includes the following steps:

s100: welding and fixing a first connection plate 60 on the upper part of the beam frame 50, and integrally drilling a first assembly hole 61 on the first connection plate 60 and the beam frame 50;

s200: welding and fixing a second connection plate 70 to the bottom of the beam frame 50, and drilling second assembly holes 72 on the second connection plate 70 and the beam frame 50 respectively to obtain a first connection member 10 and a second connection member 20;

s300: inserting and fixing the first connection assembly 30 into the first fitting hole 61 of the first docking member 10 and the first fitting hole 61 of the second docking member 20;

s400: inserting and fixing a second connection assembly 40 into the second fitting hole 72 of the first docking member 10 and the second fitting hole of the second docking member 20. According to the scheme, the effects of prefabricating each part in a factory and then integrally assembling the parts on a construction site can be realized, the operation is convenient and fast, and the connection reliability is high.

And because the first assembly hole 61 on the first connection plate 60 and the second assembly hole 72 on the second connection plate 70 are both opened during the manufacturing of the parts and then are connected with the truss in a welding manner, the need for on-site hole matching and drilling like the traditional connection structure is avoided, and the operation time is long and the difficulty is high.

With continued reference to fig. 2 and 3, in some embodiments, the beam frame 50 includes a bottom cross beam 51, two longitudinal beams 52 and a middle cross beam 53, bottom ends of the two longitudinal beams 52 are disposed on the bottom cross beam 51, and two ends of the middle cross beam 53 are respectively connected to middle portions of the two longitudinal beams 52; the first connector board 60 is fixed to the upper portion of the longitudinal beam 52 by welding, and the second connector board 70 is fixed to the bottom cross beam 51 by welding. At this time, the bottom cross member 51, the longitudinal members 52 and the middle cross member 53 are combined to form the first connecting member 10 and the second connecting member 20 which are stable in structure, so that the connecting structure 200 after being assembled and formed can reliably connect and support the upper chord 310 and the lower chord 320. Also, the first and second docking plates 60 and 70 located above and below facilitate strengthening of the connection tightness of the first and second docking members 10 and 20 in a vertical plane.

Further, in the first connection member 10 with in the second connection member 20, first pilot hole 61 is two and sets up along vertical interval, is in two relative in the same horizontal plane first pilot hole 61 is a set of, first connecting elements 30 is two, and with two sets of first pilot hole 61 one-to-one assembled connection. This ensures that the connection mechanism has sufficient connection strength, and ensures the surface parallelism of the left and right upper chords 310 and the straightness of the escalator or moving walkway when the truss 300 is connected by the connection structure 200.

Further, in the first connection member 10 and the second connection member 20, the second assembling holes 72 are a plurality of and are arranged along a transverse interval, two opposite second assembling holes 72 in the same vertical plane are a group, the second connecting assembly 40 is a plurality of, and is connected with a plurality of groups in a one-to-one correspondence manner through the second assembling holes 72. As can be seen from the results of the mechanical analysis, the axial force on the lower chord 320 is generally the largest, so that the second assembly hole 72 for connection is disposed on the bottom cross beam 51 (i.e., the bottom of the truss 300) and connected by the second connecting assembly 40, the connection force is optimized more directly and effectively, and the deformation resistance effect and the deformation resistance capability are better. At this moment, not only can the surplus space of truss 300 bottom be fully utilized, do not influence other parts (such as step, guide rail are drawn, railing etc.) normal assembly connection simultaneously, simultaneously through arranging multiunit second coupling assembling 40, can make the connection intensity of refuting connection structure 200 and truss 300 higher, the bottom can bear bigger axle power, guarantees escalator or moving walk's bulk rigidity, applicable in the big span occasion of high lift and no intermediate strut.

It should be noted that the first connecting assembly 30 and the second connecting assembly 40 are preferably torsional shear type high strength bolts, which are connected by friction, that is, the friction between the contact surfaces is used to bear the load. Accordingly, the first and second fitting holes 61 and 72 are bolt holes. In actual use, the escalator or the moving sidewalk is usually subjected to variable loads (such as loads applied by passengers with different weights), so that the connection in the mode has good anti-fatigue effect, and the service life of the truss 300 can be properly prolonged; the existing connection structure usually uses a hinged bolt, and a screw rod is directly stressed, so that a bolt hole needs to be drilled on site to ensure the processing precision, the connection mode adopts a high-strength bolt friction type connection, so that the screw rod can not bear the force, the gap between the hole wall of the bolt hole and the outer wall of the screw rod can reach 2mm, and the operation difficulty is reduced.

It should be further noted that the hole diameter of the bolt hole on the bottom cross beam 51 is at least 2mm larger than the hole diameter of the bolt hole on the second connector plate 70, so as to facilitate the subsequent alignment and assembly. Because of the friction connection, the screw rod is not stressed at the moment, so that the aperture of the bolt holes in the first connection plate 60 and the second connection plate 70 is at least 2mm larger than the diameter of the screw rod, and the alignment difficulty is effectively reduced.

With reference to fig. 2 and fig. 3, in addition, on the basis of any of the above embodiments, the connection structure 200 further includes a pre-positioning assembly 80 and a reinforcing backing plate 90, the reinforcing backing plate 90 is disposed on the longitudinal beam 52, the first connection member 10 and the second connection member 20 are further provided with pre-positioning holes penetrating through the reinforcing backing plate 90 and the longitudinal beam 52, and the pre-positioning assembly 80 is inserted and fixed in two adjacent pre-positioning holes. Through the pre-positioning assembly 80 and the pre-positioning holes on the two sides in assembly connection, the first connection component 10 and the second connection component 20 can be accurately aligned in assembly connection, and the assembly difficulty of each subsequent connection component and the corresponding assembly hole is reduced.

Specifically, the pre-positioning assembly 80 includes a socket pin and a backing plate. The base plate is welded and fixed on the longitudinal beam 52 in advance, then a pre-positioning hole is integrally drilled on the base plate and the longitudinal beam 52, and then the socket pin is connected with the pre-positioning holes on the two sides in an inserting mode. The purpose of arranging the backing plate is to increase the connection strength, improve the hole edge strength of the pre-positioning hole and prevent the hole edge from bursting due to overlarge pressure.

The second connection plate 70 is provided with a positioning groove 71, and the positioning groove 71 is used for inserting the end of the lower chord member 320. Therefore, the lower chord 320 and the second connection plate 70 can be assembled and positioned, and the connection position precision is ensured.

With reference to fig. 2 and fig. 3, on the basis of any of the above embodiments, each of the first and second segmented trusses includes an upper chord 310 and a lower chord 320 arranged vertically side by side, each of the first and second connection members 10 and 20 further includes a first reinforcing plate 100 and a second reinforcing plate 110, the first reinforcing plate 100 is fixedly connected to the upper chord 310 and the longitudinal beam 52, and the second reinforcing plate 110 is fixedly connected to the bottom cross beam 51 and the longitudinal beam 52. By additionally arranging the first reinforcing plate 100 and the second reinforcing plate 110, the overall structural strength and rigidity of the connection structure 200 can be further enhanced, and the variable load bearing capacity is improved.
