Detailed description of the invention

Hereinafter, based on Fig. 1～Fig. 6, the escalator 10 of an embodiment of the invention is said Bright.

(1) escalator 10

Based on Fig. 1, the structure of escalator 10 is illustrated.Fig. 1 is to observe escalator from side The explanatory diagram of 10.

As the truss 12 of the framework of escalator 10 cross over building 1 upper strata spandrel girder 4 and under Layer spandrel girder 4 and use support angle 2,3 to be supported by.Will be rear about this support angle 2,3 Face describes in detail.

The Machine Room 14 of the upper layer side in the upper end being positioned at truss 12 is internally provided with and makes step 30 row The driving means 18 entered.This driving means 18 has: be made up of induction conductivity (induction machine) Motor 20, decelerator, it is installed on the output chain gear of the output shaft of this decelerator, driven by this output chain gear Dynamic drives chain 22 and makes rotating stopping and keeping the disk brake of halted state of motor 20 64.Drive sprocket 24 is made to rotate by this driving chain 22.Further, in the Machine Room 14 of upper layer side Portion, is provided with the control portion 50 controlling motor 20 via DC-to-AC converter 64.

The Machine Room 16 of the lower layer side in the bottom being positioned at truss 12 is internally provided with driven sprocket 26. Setting up between the drive sprocket 24 and the driven sprocket 26 of lower layer side of upper layer side has pair of right and left ring-type Step chains 28,28.In pair of right and left step chains 28,28, multiple step is equally spaced installed 30.The wheel 301 of step 30 is advanced on the not shown guide rail be fixed in truss 12, wheel 302 advance on the guide rail 25 be fixed in truss 12.

Erect in the left and right sides of truss 12 be provided with pair of right and left and be made up of glass plate railing 36, 36.The top of this railing 36 is provided with armrest cover plate 361, sets in the upper end of armrest cover plate 361 Being equipped with handrail track 362, handrail 38 is synchronously advanced along this handrail track 362 with step 30. Will be described in detail later about this armrest cover plate 361.

Positive basifacial in the upper layer side of railing 36 is provided with the front skirt guard 40 of upper layer side, under The positive basifacial of layer side is provided with the front skirt guard 42 of lower layer side, from front skirt guard 40,42 Protrude the inlet portion 46,48 of gateway as handrail 38 respectively.Under the side of railing 36 Portion is provided with skirt guard 44, and step 30 is advanced between pair of right and left skirt guard 44,44.? The medial surface of the skirt guard 44 of levels be respectively arranged with console panel 52,56, speaker 54,58.

At the stopping port between the pair of right and left skirt guard 44,44 of upper layer side and be at machinery The top board face of room 14, is flatly provided with the lifting board 32 of upper layer side.In the left and right one being positioned at lower layer side To the stopping port between skirt guard 44,44 and be the top board face in Machine Room 16, flatly set It is equipped with the lifting board 34 of lower layer side.The comb of comb teeth-shaped it is provided with in the front end of the lifting board 32 of upper layer side Part 60, is also equipped with comb teeth-shaped comb part 62 in the front end of the lifting board 34 of lower layer side.

(2) structure of support angle 2,3

Secondly, based on Fig. 2～Fig. 6, support angle 2,3 is illustrated.

Support angle 2 is affixed to the parts on the top in the minor face face of truss 12 upper layer side.This bearing angle OBL metal plate benging is become " く " shape by ferrum 2, by horizontal plate 64 and perpendicular plate 66 Constitute.Perpendicular plate 66 is welded in the members of frame on the top in the minor face face of truss 12 and is fixed, level Plate 64 highlights along the length direction of truss 12.By this horizontal plate 64 is placed in holding of building 1 The upper surface of weight beam 4, it is possible to escalator 10 is arranged at building 1.

The support angle 3 of the lower layer side of truss 12 also has same structure, and is placed in building The spandrel girder 4 of 1.

But, for this horizontal plate 64, will be referred to as " coordinating by the repeating part being placed in spandrel girder 4 Surplus ", even if building transversely offsets because of earthquake etc., it is also possible to utilize this cooperation surplus prevent from Dynamic staircase 10 falls from building.But, due to the change of anti-seismic construction, need to make this cooperation surplus Extension, therefore, in the present embodiment, for the cooperation surplus by this support angle 2,3 Extended and extended parts 68 are installed.

Extended parts 68 are by metal upper plate 70 and lower plate 72 stacking fixing portion Part, the size of the width of upper plate 70 and lower plate 72 is the chi of the width with support angle 2 Very little identical length, the thickness of support angle 2 is identical with the thickness of lower plate 72.Further, upper plate 70 Length direction length from want extended coordinate surplus length decision, as it is shown on figure 3, In the case of being intended to coordinate the extended Ll of surplus, have this L1 and upper plate 70 and horizontal plate 64 The length of L3 obtained by the length total of overlapping L2.

Lower plate 72 is to be welded in the lower surface of upper plate 70 and the parts fixed, is fixed in figure 3 The part not repeated with horizontal plate 64 in upper plate 70.Thus, the length of the length direction of this lower plate 72 Degree is L1.

The end 76 of the part overlapping with horizontal plate 64 in upper plate 70 is formed with rectangle as shown in Figure 2 Notch 74, be formed as concavo-convex.

Arrange in the case of parts 68 are fixed on support angle 2 will extend over, as in figure 2 it is shown, operation Upper plate 70 is overlapped horizontal plate 64 from by the top being placed in the support angle 2 of spandrel girder 4 by personnel On, lower plate 72 is positioned on spandrel girder 4.Then, operating personnel is by horizontal plate 64 and upper plate 70 Weld along concavo-convex end 76.Thus, the cooperation surplus of support angle 2 sets by extension Put parts 68 and elongated L1.

Support angle 3 for lower layer side installs extended parts 68 too.

(3) effect

According to present embodiment, only by the support angle 2 at the spandrel girder 4 being placed in building 1 Upper the most securing elongated parts 68 are set just can extended cooperation surplus, it is possible to strengthen anti-seismic construction.

In the case of installing extended parts 68 on the upper plate 70 of support angle 2, only by upper Plate 70 is welded in horizontal plate 64 from top, it is possible to easily carry out this operation, it is possible at manpower Aspect, money aspect suppression cost.

Further, the end 76 of the upper plate 70 of extended parts 68 is formed as concavo-convex, therefore welds Position is elongated, it is possible to firmly fix.

(4) variation 1

Variation 1 is illustrated.In the above-described embodiment, will extend over the upper plate of parts 68 is set The end 76 of 70 is formed as concavo-convex, but is not limited to this, it is also possible to be formed as linearity, and along This linearity welds.

(5) variation 2

Based on Fig. 7 and Fig. 8, variation 2 is illustrated.Variation 2 is with above-mentioned embodiment not The end 76 being the upper plate 70 of support angle 2 with point is linearity, by upper plate 70 and horizontal plate 64 Utilize many bolts 78 to fix this point not by welding.

Even if utilizing many bolts 78 will extend over like this to arrange parts 68 and be fixed on support angle 2, also The length of the cooperation surplus of support angle can be extended simply.

Further, the fixing means of extended parts 68 is also only and utilizes many bolts 78 to fasten, Therefore its operation is easy.

(6) other

Further, in the above-described embodiment, it is applied to escalator 10 and is illustrated, but replace Moving sidewalk can also be applied in this.

In the above description an embodiment of the invention is illustrated, but this embodiment is only Pointed out as an example, be not intended to limit the scope of invention.These new embodiment energy Enough implement in other various modes, it is possible to carrying out each in the range of the purport without departing from invention Kind is omitted, replaces, is changed.These embodiments and deformation thereof are contained in the scope of invention, purport, And it is contained in the scope of the invention described in claims and equivalent thereof.
