Detailed description of the invention
Referring to accompanying drawing, embodiments of the invention are described.In the drawings and in which, adopt identical symbol to represent relative to identical or similar inscape, and omit identical explanation.
Be described as the one in the apparatus of passenger conveyor of embodiments of the invention and escalator referring to Fig. 1 to Fig. 4.
Fig. 1 is the unitary side view of apparatus of passenger conveyor of the present invention.Escalator in the present embodiment as shown in Figure 1, there is the framework 4 be arranged on building structure, be arranged on the floor, gangway 71 of length direction two ends of this framework 4,72, annularly connect and between these floors, gangway 71,72 loopy moving step 8, for drive the actuating device M of this step 8 and along the rotation direction of step 8 at the relative railing 13 of left and right directions.The framework 4 of the present embodiment is arranged across upper floor 51 and lower floor 52.Be respectively arranged with bearing beam 53 in the end of the length direction of framework 4, framework 4 is supported on upper floor 51 and lower floor 52 by bearing beam 53.
Wherein, framework 4 is alongst divided into multiple framework section, and adjacent framework section is connected to each other by bolt etc. at connecting bridge S.Illustrate only a connecting bridge S in FIG, but connecting bridge S also can there be more than two places.So, by framework being divided into multiple framework section, can by each framework section after factory manufactures, the erecting stage of escalator is transported in units of framework section, after this assemble by connecting connecting bridge S, thereby, it is possible to make the manufacture of escalator, transport and installation exercise become more convenient.
Fig. 2 is the enlarged drawing of the material component that winds up of connecting bridge S between the framework of prior art.Longitudinal material 43 and not shown in figure 2 oblique material 44 be connected with the material 41 that winds up by welding Y.When longitudinal material 43 and oblique material 44 being connected on the material 41 that winds up by welding Y, the material 41 that winds up can produce distortion because of welding heat, and likely producing displacement is the dislocation of g.When there occurs large dislocation, existing and being difficult to also carry out with the material 41 that winds up that fish plate A1, A2 clamp adjacent framework section the problem that connects with bolt class B.In addition, exist too in lower edge material in the problem carrying out producing when welding Y distortion.
Fig. 3 is the section drawing at the I-I place of Fig. 1 of the present invention, and Fig. 4 is the section drawing (in Fig. 4 not shown railing 13 and balustrade stay pedestal 13A) at the II-II place of Fig. 3.
As shown in Figure 3, the framework 4 of the escalator of the present embodiment is made up of left-side member 4A, right-hand member 4B, upper beam 4C and lower beam 4D.In addition, there is in the inner side of left-side member 4A and right-hand member 4B the longitudinal 5 (5A, 5B) being provided with guide rail 10 and skirt section backplate 11.Longitudinal 5 (5A, 5B), upper beam 4C and lower beam 4D are arranged on longitudinal material 43 respectively by bolt class (such as fitting bolt R).In addition, lower beam 4D is provided with food tray 12.
As shown in Figure 3 and Figure 4, in the present invention, left-side member 4A is assembled into truss-like by will wind up material 41, lower edge material 42, longitudinal material 43 and oblique material 44 and is formed, when assembling, utilizing fixture etc. longitudinal material 43 and oblique material 44 to be arranged on across ground winds up on material 41 and lower edge material 42, be processed to form fraising at lap, and carry out fastening with fitting bolt R.In addition, the assemble method of right-hand member 4B is identical with left-side member 4A.
As mentioned above, wind up on material 41 and lower edge material 42 by with fitting bolt R longitudinal material 43 and oblique material 44 being fixed on, do not need to carry out welding Y when connecting longitudinal material 43 and oblique material 44, wind up material 41 and lower edge material 42 can not produce distortion because of welding heat, so the connection between the adjacent framework section with framework becomes easily this advantage.In addition, owing to using fitting bolt R to connect, so do not need to weld, therefore, it is possible to provide a kind of making of framework 4 good and renovate apparatus of passenger conveyor easily.
In addition, in the present invention, do not use plain bolt and use fitting bolt R.When adopting plain bolt longitudinal material 43 and oblique material 44 to be connected to wind up material 41 and lower edge material 42, between bolt and bolt hole, leave gap, the problem that intensity when there is earthquake etc. is low.And in the present invention, owing to using fitting bolt R, so substantially there is not gap between fitting bolt R and bolt hole.Therefore, have and can guarantee this advantage of the intensity identical or larger with weld strength when earthquake etc.
Again, in the present invention, as material 41 and the lower edge material 42 of winding up, can adopt current in apparatus of passenger conveyor widely used L shape steel, but the present invention is not limited to this, as material 41 and the lower edge material 42 of winding up, also wind up material 41 and the lower edge material 42 that are formed by steel plate bending can be adopted, so, lightweight can not only be realized, and compared with using the occasion of common L shape steel, the height h1 of wind up material 41 and lower edge material 42 can also be regulated, h2 (with reference to Fig. 3), so have the effect can guaranteeing the fixed space of fitting bolt easily.
In figure 3, from the viewpoint of making property and intensity, preferably by fitting bolt R, longitudinal 5 (5A, 5B), upper beam 4C and lower beam 4D are arranged on longitudinal material 43 respectively, but the present invention is not limited to this, welding also can be utilized to install.When utilizing welding to install, longitudinal material 43 may produce distortion because of welding heat, even if but longitudinal material 43 deforms, because the impact of this distortion on wind up material 41 and lower edge material 42 is little, so large problem can not be there is when connecting bridge S connects.
In the present invention, longitudinal material 43 and the fixing of oblique material 44 preferably all carry out with fitting bolt R, but because longitudinal material of two ends (vicinity of bearing beam 53) of the length direction of framework 4 does not exist the connecting bridge S be connected with adjacent framework section, so can be connected by welding yet.In the present invention, the displacement g that material 41 and lower edge material 42 produce because of distortion as long as wind up is in allowed band, then also can being arranged to longitudinal material 43 of more than requirement ratio (such as more than 90%) and oblique material 44, to use fitting bolt R to carry out fastening.
Again, be described for escalator in the present embodiment, but this structure also can be applied to the electric channel not producing difference of height.
More than by embodiment, the invention has been described, but a structure described above only example, the present invention can carry out suitable change in the scope not departing from its technological thought.
