Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fully loaded portable electrical device which has an inspection passage inside and can be transported and installed while electrical equipment such as a closed switchboard is housed therein.

This type of electrical equipment consists of a housing consisting of a base that can be transported as a unit, a side wall installed on the outer periphery of the base, and a roof that covers the top surface of the side wall. The side walls and roof were assembled from various plate-shaped sheet metal members and various trusses one by one by tightening bolts. The assembly work overlapped with the installation work of internal electrical equipment, resulting in poor work efficiency. Furthermore, assembling the roof required work at height, which was dangerous.

In particular, in this invention, the entire roof is assembled in the previous process like a prefabricated panel, and the prefabricated roof assembly is placed on the upper end of the side wall installed on the outer periphery of the base, so that it can be easily assembled. , which attempts to eliminate the drawbacks of the conventional one.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, 100 is the base 101 and the roof 103
A housing for a complete portable electrical device consisting of a Reference numeral 1 denotes an entrance/exit door provided on the side wall 102. The base 101 is constructed by welding an outer peripheral beam 2, a horizontal beam 3 connecting the outer peripheral beam 2, and a floor plate 4 disposed on the upper surface thereof.

Reference numeral 104 denotes electrical equipment such as a switchboard placed on the base. The side wall 102 is composed of an outer wall panel 5, an inner panel 6, and a heat insulating material 40 disposed therebetween.

Flanges 5A and 5B are provided at the upper and lower ends of the outer wall panel 5.
is formed and fixed to the base outer peripheral beam 2 by bolt members 30 and nut members 31 welded to the inside of the lower end flange 5B. Reference numeral 7 denotes an outer truss disposed around the entire outer circumference of the roof 103. This outer circumferential truss 7 has a lip groove-shaped cross section consisting of a vertical leg 7A, an upper horizontal leg 7B, a lower horizontal leg 7C, an upper lip leg 7D, and a lower lip leg 7E. The opening on the opposite side of the vertical leg 7A is arranged facing outward of the housing 100. Reference numeral 8 designates a plurality of horizontal trusses whose both ends are welded to the vertical legs 7A of the outer circumferential truss 7, and although an H-shaped cross section is shown in the figure, other cross-sectional shapes may be used. Reference numeral 9 denotes a vertical auxiliary truss disposed on the upper surface of the horizontal truss 8, which may be omitted when the width of the housing 100 is short.

A ceiling panel 10 is supported by a horizontal truss 8. A roof panel 11 is fixed at both ends to the upper horizontal leg 7B of the outer truss 7 via bolts and nut members 35.

The roof panel 11 has vertical flanges 11A and horizontal flanges 11B bent inward from the vertical flanges 11A on both sides in the longitudinal direction.
Reference numeral 12 denotes a connecting cap that covers the entire length of the abutting portion of the adjacent roof panels 11, and is fixed to the horizontal flanges 11B, 11B of the adjacent roof panels via bolts and nut members 35. Also roof panel 1
A heat insulating material 40 is disposed between the ceiling panel 1 and the ceiling panel 10. Reference numeral 13 denotes an upper plate that closes the opening of the outer circumferential truss 7 in the final stage of assembly.

The procedure for assembling the fully loaded portable electric device configured as described above will be explained below.

First, the electrical equipment 104 is installed on the base 101. Next, a heat insulating material 40 is placed in advance and the inner wall panel 6 is stretched, and a plurality of outer wall panels 5 connected together are installed and fixed on the base outer peripheral beam. Since a nut member 32 is welded to the inside of the upper end flange 5A of the outer wall panel, the entire plurality of outer wall panels can be lifted up and installed easily using this nut member. Furthermore, since the bolt member 30 is welded to the inside of the lower end flange 5B, the nut member 31 can be tightened only from the outside of the housing 100.
Therefore, there is no problem even if the electrical equipment 104 is installed adjacent to the side wall. All other constituent members of the roof 103 except for the upper plate 13 can be assembled on the ground in separate steps. Each transformer that forms the framework is welded and strong, and the whole can be lifted up and installed on the upper end of the side wall 102 using a suitable lifting tool. Connection with the side wall 102 is achieved by tightening bolt members 33 from the outward openings of the outer truss 7 disposed around the outer periphery of the roof 103. Then, the upper plate 13 is fixed to the upper and lower lip legs 7D, 7E of the outer circumferential truss via bolt members 34. By wrapping the lower end of the upper plate 13 against the side wall, the joint between the outer truss 7 and the upper end 5 of the outer wall panel is made waterproof. The joint between the roof panel 11 and the upper plate 13 is waterproofed with caulking material 41.

As described above, according to the present invention, the work of installing electrical equipment on the base, assembling the side walls, and assembling the roof can be performed with almost no duplication, resulting in extremely high work efficiency. Particularly in the past, most of roof assembly involved dangerous work at high places, such as mounting ceiling panels and roof panels by climbing on top of trusses. and tighten the upper plate 13.
Installation is only required, and both can be done safely while standing on an elevated work platform.

Although the illustrated embodiment is a single roof assembly, if the roof 103 to be assembled is large and difficult to lift, it may be divided into a plurality of parts corresponding to the joints of the roof panels 11. This also has the same effects as above.

Furthermore, the roof may be made to have an inclination by changing the heights of the front and rear peripheral trusses and the heights of a plurality of auxiliary trusses.
