Abstract
The utility model provides a vertical installation structure of a closed bus, which comprises a pair of supporting steel frames and expansion bolts, wherein the supporting steel frames are arranged on two sides of an opening of a floor slab, the side edge of each supporting steel frame is provided with an opening, two sides of a shell of the closed bus are provided with radial connecting columns corresponding to the openings of the supporting steel frames, the radial connecting columns are provided with threads and penetrate through the openings, and the supporting steel frames and the shell of the closed bus are detachably and tightly fixed by utilizing screw caps and the threaded connection of the radial connecting columns. The support angle steel is connected with the closed bus shell by the radial bolt, so that the closed bus shell cannot be damaged during installation and disassembly. And the supporting angle steel can be tightly and accurately connected with the shell of the enclosed bus through the transverse movement of the supporting angle steel and the up-and-down adjustment and fixation of the screw rod and the screw cap. According to the utility model, by adjusting the pretightening force of the radial bolts of the support angle steel and the closed bus shell, part of the gravity of the closed bus can be shared to the angle steel bracket, and the stress of the lower bracket is reduced.
Description
Technical Field
The utility model belongs to the field of equipment installation, and particularly relates to a vertical installation structure of a closed bus.
Background
The enclosed bus is widely applied to the lead of power supplies with current of more than 2000A in occasions such as power plants, substations, industries, civilian use and the like. The enclosed busbar will pass vertically through the floor as required by the lead arrangement, mounted vertically. The existing fixing method for the through floor is mainly characterized in that channel steel is paved at the opening of the floor and is welded and fixed with a shell of a closed bus, and the method has high requirements on welding process, and the sealing performance of the shell can be influenced due to poor welding, and the closed bus is not easy to disassemble, so that a flexible and reliable vertical mounting structure needs to be researched.
Disclosure of Invention
The utility model aims to provide a vertical mounting structure of a closed bus, which is convenient to disassemble and assemble and can not damage a shell of the closed bus. Therefore, the utility model adopts the following technical scheme.
The utility model provides a perpendicular mounting structure of enclosed busbar, its characterized in that includes a pair of support steelframe and expansion bolts, a pair of support steelframe setting passes the floor trompil between two parties in the both sides of floor trompil, enclosed busbar, a pair of support steelframe passes through expansion bolts fixes on the floor, it has the trompil to support the steelframe side, and the both sides of enclosed busbar shell correspond the trompil that supports the steelframe and set up radial spliced pole, radial spliced pole has the screw thread and passes the trompil utilizes nut and radial spliced pole threaded connection, will support the steelframe and closely fix with enclosed busbar shell detachably.
Further, the support steelframe is adjustable high support frame, including lower floor's support and the upper strata support of adjustable height, lower floor's support passes through expansion bolts fixes on the floor, upper strata support sets up the trompil.
Furthermore, the lower-layer bracket adopts a channel steel bracket, the upper-layer bracket adopts support angle steel, the channel steel bracket is attached to a floor slab opening and fixed on the floor slab through the expansion bolt, one end of the connecting screw penetrates through the channel steel bracket, and the other end of the connecting screw penetrates through the support angle steel; the side edge of the support angle steel is provided with the opening.
By adopting the technical scheme, the bus bar support device is convenient to install and reliable in support, the support angle steel is connected with the closed bus bar shell through the radial bolts, and the closed bus bar shell cannot be damaged during installation and disassembly. And the supporting angle steel can be tightly and accurately connected with the shell of the enclosed bus through the transverse movement of the supporting angle steel and the up-and-down adjustment and fixation of the screw rod and the screw cap. According to the utility model, by adjusting the pretightening force of the radial bolts of the support angle steel and the closed bus shell, part of the gravity of the closed bus can be shared to the angle steel bracket, and the stress of the lower bracket is reduced.

Fig. 1 and 2 are side views of an embodiment of the present invention in different directions.
Detailed Description
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.
Referring to the attached drawings, the enclosed bus vertical installation structure provided by the utility model comprises a pair of supporting steel frames which are arranged on two sides of a floor slab opening 100, and each supporting steel frame comprises a channel steel bracket 2, a supporting angle steel 3 and a connecting screw rod 4. The enclosed bus 1 penetrates through a floor slab opening 100 in the middle, the channel steel bracket 2 is attached to the floor slab opening and fixed on the floor slab through an expansion bolt 5; one end of the connecting screw rod 4 penetrates through the channel steel bracket, and the other end of the connecting screw rod penetrates through the support angle steel 3; the side of the support angle steel 3 is provided with an opening 31 for penetrating through the radial columnar connecting piece 11 on the closed bus casing.
At least one section of the columnar connecting piece 11 of the enclosed bus shell is a screw, and the support angle steel 3 and the enclosed bus shell are detachably and tightly fixed by utilizing the connection of a screw cap and the screw.
The connecting screw rod 4 is connected with a plurality of nuts and used for fixing and locking the position of the upper connecting support (the supporting angle steel 3) by the upper and lower nuts after the height of the upper connecting support is adjusted in place.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, i.e. all equivalent variations and modifications made by the present invention are covered by the scope of the claims of the present invention, which is not limited by the examples herein.
