Mounting and dismounting mechanism for cross arms of pole-mounted transformer and using method

Abstract

The invention discloses a mounting and dismounting mechanism for cross arms of a pole-mounted transformer and a using method. The mounting and dismounting mechanism for the cross arms of the pole-mounted transformer comprises a first cross arm, a second cross arm, a connecting rod, a compaction wedge block, a limiting device, a handle, a guide shaft and a handle pressing rod, the first cross arm and the second cross arm are symmetrically arranged on the two sides of a telegraph pole, the connecting rod penetrates through the first cross arm and the second cross arm, the compaction wedge block is connected with the second cross arm, the handle pressing rod penetrates through the compaction wedge block, the handle pressing rod and the compaction wedge block are combined in a welded mode, the limiting device is connected with the second cross arm, through cooperation of the handle pressing rod on the wedge block, the handle rotates around the guide shaft, the wedge block moves up and down, the first cross arm and the second cross arm tightly press and are separated from a wire rod, or the handle operates a limiting rod on the limiting device to enable the limiting rod to rotate in place to jam a rack rod. According to the mounting and dismounting mechanism for the cross arms of the pole-mounted transformer and the using method, bolt-free rapid clamping and separation of the pole-mounted transformer cross arm are realized, the clamping process of the cross arm can be completed on one side, and the labor amount is reduced.

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.
