Description

Technical Field

[0001] The invention relates to an installation device for a common box enclosed busbar in a power generation project, and in particular to an installation device for a common box enclosed busbar on a suspended bracket and an installation method. Background Art

[0002] The busbar is the electrical connection line between the transformer and the high-voltage power distribution device used in the factory. Since the busbar is generally long, the busbar manufacturer first makes a common box enclosed busbar with a length of about 6 meters per section. After the common box enclosed busbar is transported to the site, the common box enclosed busbars are connected to form a busbar with bolts or by welding. There are two ways to install the common box enclosed busbar on site: one way is to install the enclosed busbar on the frame structure outside the A column, and each group of frames are connected together with steel beams. The common box enclosed busbar is hoisted to the high-altitude frame by a crane with a manual fall chain; the other way is to install the enclosed busbar on a suspended bracket. The suspended bracket is composed of frame hangers arranged at equal intervals. A common box enclosed busbar is placed between two adjacent frame hangers. The common box enclosed busbars on all frame hangers are connected together to form a busbar. When existing equipment has been arranged under the suspended bracket, there is a problem that the crane cannot enter the site to hoist the common box enclosed busbar. Summary of the invention

[0003] The present invention provides a device and method for installing a common box enclosed busbar on a suspension bracket, which solves the technical problem of how to safely and efficiently install a common box enclosed busbar when existing equipment is arranged below the suspension bracket.

[0007] A hand-pull fall chain is arranged on the suspension frame.

[0008] A method for installing a common box enclosed busbar installation device on a suspended bracket comprises the following steps:

[0009] Step 1: Place the pre-positioned common box enclosed busbar between the front flatbed trolley and the rear flatbed trolley on the ground below the starting end suspension frame, and fix the pre-positioned common box enclosed busbar and the two flatbed trolleys together through the front clamp and the rear clamp respectively;

[0010] Step 2: The crane uses the lifting rope to place the pre-positioned common box enclosed busbar with two flatbed trolleys on the parallel guide rails on the starting end suspension frame;

[0011] Step 3: Move the pre-positioned common box enclosed busbar to the suspension bracket on one side of the already-positioned common box enclosed busbar by moving two flatbed trolleys on parallel guide rails;

[0012] Step 4: Use the hand-pull fall chain set on the suspension frame to suspend the pre-positioned common box enclosed busbar with two flatbed trolleys, and remove the parallel guide rails on the two adjacent hangers directly below the suspended pre-positioned common box enclosed busbar;

[0013] Step 5: Lower the pre-positioned common box enclosed busbar with two flatbed trolleys to the bottom beams of the two hangers on the adjacent hangers directly below by using the hand-pull chain set on the suspension frame, and remove the front hoop, rear hoop, front flatbed trolley and rear flatbed trolley;

[0014] Step 6: Connect the pre-placed common box enclosed busbar with the already-placed common box enclosed busbar.
