Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to low-voltage busbar bridges, and in particular to an assembled low-voltage busbar bridge. Background Art
[0002] Current low-voltage busbar bridges are generally assembled by welding cold-rolled steel plates. The cold-rolled steel plates must undergo a series of process treatments such as pickling, phosphating, and plastic spraying to increase their service life. In addition, the welding and assembly are not conducive to packaging and transportation, resulting in relatively high processing costs. In addition, the low-voltage busbar bridge adopts welding connections, which means that the connected parts are usually not replaceable, so its flexibility of use is relatively poor. In addition, the insulating busbar clamps in the existing low-voltage busbar bridge are fixed to the connecting rod by screws, that is, the threaded end of the screw passes through the circular hole on the connecting rod and is connected to the threaded hole at the bottom of the insulating busbar clamp, resulting in the insulating busbar clamp being unable to be longitudinally adjusted as needed. Utility Model Content
[0003] In order to solve at least one technical problem existing in the low-voltage busbar bridge in the background technology, the purpose of the present utility model is to provide an assembled low-voltage busbar bridge to overcome the existing technical problem.

[0006] By adopting the above technical solution, the pier and the bridge body are connected in a detachable manner. After the pier and the bridge body are manufactured separately, they can be packaged separately, which is more convenient than packaging the pier and the bridge body after they are welded together. The U-shaped frame and the insulating busbar clamp are connected by screws, and strip-shaped through holes are provided on the U-shaped frame, thereby realizing adjustment of the fixed position of the insulating busbar clamp. The position can be adjusted according to actual use needs, solving the problem that the existing insulating busbar clamp cannot adjust its position.

Using galvanized steel for the bridge body provides the necessary mechanical strength and protection, eliminates the need for surface treatment, and effectively resists short-circuit-induced structural heating, thereby enhancing the level of protection.
[0009] In some embodiments, the bridge pier is made of aluminum-zinc plate and has a hollow rectangular structure, mainly composed of four detachably connected side panels, and heat dissipation holes are respectively provided on the front and rear sides of the bridge pier.
[0010] In some embodiments, the C-shaped member is composed of a plurality of C-shaped bodies that are detachably connected transversely, and a reinforcing rod is fixedly connected to both ends of each C-shaped body.
[0011] In some embodiments, the U-shaped frame includes a bottom rod and side rods, both ends of the bottom rod are connected to the two side rods by screws, and a plurality of adjustment holes for adjusting the fixed height of the bottom rod are vertically provided on the side rods.
[0012] In some embodiments, the bridge body and the pier are connected by bolts and nuts, and a plurality of the strip-shaped through holes are longitudinally spaced apart.
[0013] In some embodiments, each of the U-shaped frames is vertically adjustable and connected to a floor bracket, and the floor bracket is provided with a plurality of connecting through holes.
[0014] In some embodiments, the insulating busbar clamp includes a first busbar clamp and a second busbar clamp, the height of the first busbar clamp is higher than the height of the second busbar clamp, and the vertical width of the busbar socket on the first busbar clamp is greater than the vertical width of the busbar sockets on the two busbar clamps on the second busbar clamp.
[0015] In some embodiments, a lifting assembly is further included, comprising a lifting joist, a lifting screw, and a fixing. At least two lifting joists are provided and disposed at the bottom of the bridge body. The lower end of the lifting screw passes through a through hole in the lifting joist and is connected to a first nut, while the upper end passes through a through hole in the fixing and is connected to a second nut. The lifting assembly enables the busbar bridge to be hoisted and installed. BRIEF DESCRIPTION OF THE DRAWINGS
