Description

A multi-purpose adjustable busbar welding bracket combination

technical field

The invention relates to the technical field of power system line erection, in particular to a combination of multi-purpose adjustable busbar welding brackets.

Background technique

In the power system, the tubular busbar is a busbar product that uses copper or aluminum alloy tubes as conductors and is insulated externally. It has the characteristics of large rated current, high mechanical strength, good insulation performance, and wide application range. It can replace conventional rectangular busbars. The bus bar erects the power line. A single tubular or rectangular busbar is about ten meters long, so for a longer line, several busbars need to be welded together, and then lifted to the busbar support for installation.

In order to realize the seamless docking of each busbar, it is necessary to ensure that the horizontal interfaces of each single busbar are aligned during welding, and the centers of the nozzles are on the same axis, so an auxiliary bracket is required when welding the busbars. Construction workers generally use the existing materials on the construction site, such as wooden boxes and wooden blocks, to build multiple temporary supports, but such simple supports are often not stable enough and uneven in height. The busbars placed on it may not only roll back and forth, but also the interface is not easy to align. This brings great difficulty to welding work.

Contents of the invention

The lower end of the support plate is provided with a hollow cylindrical protrusion, and the surface of the protrusion is provided with threads, and the adjusting pipe fittings, the support plate and the pillars are all threaded.

The base is cross-shaped, and the four ends of the cross-shaped base are all provided with screw holes, and adjusting bolts are matched in the screw holes.

A handle is provided on the outer surface of the adjusting pipe fitting, and the direction of the connecting thread between the adjusting pipe fitting and the support plate is opposite to that between the adjusting pipe fitting and the pillar.

The invention provides a multi-purpose adjustable busbar welding bracket combination, which can respectively fix the pipe type and the rectangular busbar by using the movable roller on the support plate and the pin in the pin hole; the height of the bracket can be greatly adjusted by adjusting the pipe fittings; Adjusting bolts on the top can be fine-tuned in height from four directions; the distance between the two movable rollers can be adjusted by sliding the bracket in the chute of the support plate to support tubular busbars of different sizes, and multiple pin holes on the support plate can be used To support rectangular busbars of different sizes. The present invention is detachable as a whole, and is easy to install. When in use, it can support busbars of different types and sizes for welding and accurately adjust the height, which greatly reduces the difficulty of welding work.

Detailed ways

Example 1

As shown in Figures 1 to 3, this embodiment is used to support the welding of tubular bus bars, and includes a plurality of support units, each support unit includes a support plate 3, an adjusting pipe fitting 4, a pillar 5 and a base 6, and the support plate 3 is two The side is provided with support frame 2, and described support frame 2 is inverted U shape, comprises two side struts and crossbeam, and movable roller 1 is fixed on support frame 2 crossbeams, and support plate 3 is in contact with support frame 2 both sides struts. The position is provided with a chute 10 of a certain length, and the bottom of the struts on both sides of the support frame 2 is provided with screw holes 11. When in use, the screws pass through the chute 10 and cooperate with the strut screw holes 11 to fix the support frame 2 on the support plate 3. At this moment, the diameter of the screw round head needs to be greater than the width of the chute 10 . During welding, the tubular busbar can be erected on the movable roller 1, and the tubular busbar can also be rotated by the movable roller 1 to change the welding position, which is very convenient. For tubular busbars of different sizes, the screws can be loosened first and the support frame 2 can be driven to slide in the chute 10 until the distance between the rollers on both sides is appropriate. The support plate 3 is connected with the support plate 5 through the adjustment pipe fitting 4. The lower end of the support plate 3 is provided with a hollow cylindrical protrusion, and the surface of the protrusion is provided with threads. fixed on the base 6. The outer surface of the adjustment pipe fitting 4 is also welded with a handle 9. When the ground level of the welding site is uneven, you can hold the handle 9 and rotate the adjustment pipe fitting 4 to adjust the height of a certain bracket unit upward or downward, so that the interface of the tubular busbar is located at the same level. on the horizon.

As shown in Figure 7, the support unit base 6 is a cross-shaped channel steel frame, and the four ends of the cross-shaped base 6 are provided with screw holes, and the support unit can be fine-tuned from four directions by using the adjusting bolt 7 and the adjusting nut 8 Height to ensure that the center of the nozzle of the tubular busbar is on the same axis.

Example 2

As shown in FIGS. 4 to 6 , this embodiment is used to support the welding of rectangular busbars, and includes a plurality of support units, and each support unit includes a support plate 3 , an adjusting pipe 4 , a pillar 5 and a base 6 . The difference with Embodiment 1 is that in this embodiment, the support frame 2 is not installed on the support plate 3, but a plurality of pin holes 12 are provided on the width direction of the support plate 3. For rectangular busbars of different widths, welding When inserting the pin 13 in the two pin holes 12 whose spacing is the same as the width of the bus bar, then the rectangular bus bar is fixed between the two pins 13 .

The working principle of the present invention is: when a plurality of tubular busbars need to be welded on site, firstly connect the support plates 3, adjusting pipe fittings 4 and pillars 5 of each support unit in sequence, and then according to the diameter of the tubular busbars to be welded The support frame 2 on both sides of the support plate 3 is fixed in a suitable position, and the distance between the two movable rollers 1 is ensured to be smaller than the diameter of the tubular busbar. Finally, the busbar is erected on the bracket unit and welded, and the height of the bracket unit is properly adjusted as required; When welding a rectangular bus bar, firstly connect the supporting plate 3, the adjusting pipe fitting 4 and the pillar 5 of each support unit in sequence, and then insert the pin 13 into two pin holes with the same spacing as the width of the bus bar according to the width of the rectangular bus bar to be welded 12, and finally fix the rectangular bus bar between the two pins 13, and adjust the height of the bracket unit appropriately as required.

The supporting plate 3, the adjusting pipe fitting 4, the pillar 5 and other components of each bracket unit of the present invention are detachably connected, and the distance between the movable rollers 1 for fixing the tubular busbar and the pin spacing for fixing the rectangular busbar can be adjusted. Therefore, a group of bracket units is suitable for welding of pipe types and rectangular busbars of different sizes. In addition, the height of each support unit can be greatly adjusted by setting the adjustment pipe fitting 4, and the adjustment bolt 7 on the base 6 can realize the fine adjustment of the height of the support unit, which greatly reduces the difficulty of adjusting the busbars to be welded to the nozzle level. The invention has the advantages of simple structure and convenient use, and can effectively improve the work efficiency during welding.
