The specific embodiment
Referring to Fig. 1 to Fig. 3, the first embodiment of the connecting bridge of the framework of apparatus of passenger conveyor involved in the present invention is described.
The section of the framework 1 of apparatus of passenger conveyor (for example escalator) is roughly U word shape, by the crossbeam with not shown, with bottom member, the side framework 2 of pair of right and left is connected and is formed.In addition, the side framework 2 of left and right forms by steel plate bending being processed into the section of コ word shape, has side panel 2a and the top part 2b roughly being bent by right angle and the following part 2c that are positioned at the upper and lower of side panel 2a as longitudinal.
The side framework 2 forming by said method, for ease of assembly, transport and move into scene, at length direction, be divided into side framework 2A, 2B, and by known methods such as welding, connecting panel 3A, 3B as transom be directly fixed on respectively by cutting apart on the end of the side framework 2A, the 2B that form.Certainly, relatively to the joint face 3S of connecting panel 3A, 3B be fixed in a parallel manner.
In addition, along the length direction of side framework 2, be provided with the bolt hole of the joint face 3S that runs through described connecting panel 3A, 3B, by the bolt shaft 4R of tie bolt 4 through this bolt hole, and by nut 5 be screwed into bring in running through of bolt shaft 4R carry out fastening.As shown in Figure 2, described tie bolt 4 and nut 5 are arranged in the width range of following part 2c certainly, are namely arranged in the width range of side framework 2A, 2B.
At this, importantly by the part of bearing of drawing stress that is positioned at side framework 2, to be that the bolt shaft 4R of the tie bolt 4 of following part 2c side is arranged to the centre of moment 10 that bears part of the drawing stress of side framework 2 overlapping in the plane, and preferably the axle center of the bolt shaft 4R of tie bolt 4 is arranged to consistent in the plane with the centre of moment 10.In addition, and further preferably the axle center of the bolt shaft 4R of tie bolt 4 is arranged to consistent in the plane with the centre of moment 10 on the position of following part 2c that approaches side framework 2.
In said structure, when moment of deflection acts in side framework 2, because the crooked drawing stress producing acts on the following part 2c of side framework 2 along the centre of moment 10., due to the bolt shaft 4R of tie bolt 4 be configured to consistent in the plane with the centre of moment 10, so can there is not to take the moment of deflection that bolt connecting bridge is fulcrum.Therefore, can not produce the power that the end that comprises connecting panel 3A, 3B of side framework 2A, 2B is opened, so the connecting bridge of side framework 2 can not deform.In addition, due to the bolt shaft 4R of the tie bolt 4 following part 2c near side framework 2, so, in the situation that moment of deflection acts in side framework 2, can effectively suppress the power that the meeting shown in the arrow of Fig. 1 causes the bottom of connecting panel 3A, 3B to be opened.
