A pole-mounted transformer cross-arm installation and disassembly mechanism and usage method

Abstract

A pole-mounted transformer cross-arm installation and disassembly mechanism and method of use, including a first cross-arm, a second cross-arm, a connecting rod, a compression wedge, a limit device, a handle, a guide shaft, and a handle pressure rod; the first cross-arm and the second cross arm are symmetrically placed on both sides of the pole; the connecting rod passes through the first cross arm and the second cross arm; the compression wedge is connected with the second cross arm, and the handle pressure rod passes through the compression wedge The block, the handle pressure rod and the compression wedge are welded together, the limit device is connected with the second cross arm, the handle rotates around the guide shaft, and the wedge moves up and down through the cooperation of the handle pressure rod on the wedge to realize the first cross arm. The compression and disengagement of the pole and the second cross arm and the wire rod; or the limit lever on the handle operation limit device makes it rotate in place to block the rack bar. The invention realizes fast clamping and disengagement of the cross arm of the transformer on the column without bolts, can complete the clamping process of the cross arm on one side, and reduces the labor load.

Description

technical field [0001] The invention relates to the technical field of mounting and dismounting mechanisms, in particular to a pole-mounted transformer cross-arm mounting and dismounting mechanism and a use method. Background technique [0002] In the current development of the pole-mounted transformer industry, the traditional transformer cross-arm installation method uses four long screws to fasten two cross-arms to two utility poles. During installation, at least one end of each screw rod needs to be aligned with the nut on the utility pole (high altitude), and the tightening process needs to apply external force to the nuts at both ends at the same time with a wrench to prevent the shaft from rotating and the tightening purpose cannot be achieved. It takes a long time and the operation is difficult. It often requires two people to work synchronously on both sides of the utility pole, which is time-consuming and laborious, and the efficiency is extremely low. The same go...

During installation, at least one end of each screw rod needs to be aligned with the nut on the utility pole (high altitude), and the tightening process needs to apply external force to the nuts at both ends at the same time with a wrench to prevent the shaft from rotating and the tightening purpose cannot be achieved. It takes a long time and the operation is difficult. It often requires two people to work synchronously on both sides of the utility pole, which is time-consuming and labor-intensive, and the efficiency is extremely low.
