Problems solved by technology
Therefore, the bolt holes of the connecting parts must be precisely machined, and when inserting the connecting bolts into the bolt holes, careful work must be done, resulting in a problem that the work efficiency at the installation site is reduced.
[0014] In addition, in the frame body of the passenger conveying equipment shown in Patent Document 3, since the frame body is composed of H-shaped steel, the weight of the frame body increases, and in order to connect the heavy H-shaped steel, it is necessary to connect both sides of the longitudinal plate. A large number of connecting bolts are used to connect the sides, so there is a problem that the assembly work at the installation site is labor-intensive and time-consuming, resulting in a decrease in work efficiency.

Embodiment Construction
[0045] Refer to the following Figure 1 to Figure 3 A first embodiment of the connecting portion of the casing of the passenger conveying equipment according to the present invention will be described.
[0046] A frame body 1 of a passenger conveying device (for example, an escalator) has a substantially U-shaped cross section, and is formed by connecting a pair of left and right side frame bodies 2 with a beam and a bottom member not shown. In addition, the left and right side frames 2 are formed by bending a steel plate into a U-shaped cross section, and have a side panel 2a as a vertical member, and upper side portions 2b bent at approximately right angles above and below the side panel 2a and Lower part 2c.
[0047] The side frame body 2 formed by the above method is divided into side frame bodies 2A and 2B in the longitudinal direction in order to facilitate assembly, transportation and moving into the site, and the connection plates 3A and 3B as connection members are c...

The present invention aims to provide a passenger conveying apparatus. With the passenger conveying apparatus will not need to be thickened to form plate thickness of a side frame body of a frame body, and will not cause working efficiency dropping, and a connecting part of the side frame body can be prevented from expanding. In the passenger conveying apparatus, steel plates are used to form left and right side frame bodies (2(2A,2B)) to form profiles of a frame body (1), thus connecting surfaces are used to fix each connecting piece respectively on the end part of the connecting part of the side frame bodies in an relative way, connecting bolts (4) and nuts(5) are used to fasten the relative connecting pieces along the length direction of the frame body, and bolt shafts (4R) of the connecting bolts are overlapped in plane in relative to torque centers (10) of the bearing parts of the stretching stress of the side frame bodies.
Description
technical field [0001] The present invention relates to passenger conveying equipment including an escalator with a level difference between adjacent steps in an inclined area and an electric passageway with no level difference between adjacent steps arranged on a flat or inclined ground, especially The invention relates to a passenger conveying device having a main frame in which left and right side frames are formed by bending steel plates. Background technique [0002] For example, as disclosed in Patent Document 1, there is known a passenger conveyor in which left and right side frames constituting a main frame are formed by bending a steel plate into a U-shaped cross section. In addition, Patent Document 2 proposes a technique of forming a truss-shaped side frame by pressing or bending a steel plate. In addition, Patent Document 3 discloses a technique of producing a side frame using H-shaped steel. [0003] The main frame disclosed by each of the above-mentioned pate...
