Guide ground line linear splicing sleeve hydraulic anti-bending mould for power transmission line

Abstract

The invention discloses a guide ground line linear splicing sleeve hydraulic anti-bending mould for a power transmission line. The mould comprises an upper mould and a lower mould, wherein the upper mould is internally provided with an upper inner liner, the lower mould is internally provided with a lower inner liner, and the lower surface of the upper inner liner and the upper surface of the lower inner liner are provided with mutually corresponding crimping grooves. The mould is characterized in that the left side and the right side of the lower mould are each connected with a bracket; the upper surface of each bracket is provided with a support groove for holding a splicing sleeve; the support grooves are coaxial with the crimping groove of the lower inner liner; the bottom surfaces of the support grooves and the bottom surface, on which the lower inner liner is installed, of the lower mould are in the same plane; the left side and the right side of the upper mould are each connected with a press rack; the lower surface of each press rack is provided with a press groove for pressing the splicing sleeve; the press groove is coaxial with the crimping groove of the upper inner liner; and the top surfaces of the press grooves and the top surface, on which the upper inner liner is installed, of the upper mould are in the same plane. By using the mould provided by the invention, the bending problem of a linear splicing sleeve during the crimping process of an aluminum pipe can be effectively solved, and the use quality and the one-step succeeding rate can be improved.

Description

technical field [0001] The invention relates to a device for connecting ground wires in power transmission line engineering, in particular to a hydraulic mold for straight line connecting pipes of ground wires. Background technique [0002] The project path of the transmission line is long, and the construction of the ground wire needs to be connected in a straight line. At present, the connection of the straight line pipe of the ground wire is carried out by hydraulic construction. [0003] The traditional hydraulic mold is used for hydraulic construction, the size of the die is relatively short, and the straight aluminum pipe is relatively long. Taking the hydraulic position and operation sequence of the steel-cored aluminum hinged steel-core butt-connected aluminum pipe as an example, as shown figure 1 As shown, (1-6 in the figure is the pressure application area marked according to the pressure application sequence, 7 is the aluminum wire, 8 is the steel pipe, 9 is the a...

AI Technical Summary

Problems solved by technology

During the crimping construction process, it is easy to cause stress concentration and uneven force on the edge, resulting in bending of the aluminum tube of the straight line connection during the crimping process, which reduces the construction quality
