Large-section wire splicing sleeve steel sheath support and construction method

Abstract

The invention provides a large-section wire splicing sleeve steel sheath support and a construction method. The large-section wire splicing sleeve steel sheath support comprises a support and a pressure jacking machine, the support is provided with the pressure jacking machine, and the upper end of the pressure jacking machine is connected with a fastening device. The outer side of the fastening device is provided with a limiting device, the lower end of the limiting device is connected with the support, and the lower end of the support is connected with a moving assembly. The fastening devicecan fix a splicing sleeve with a steel sheath, manual fixing is not needed, and the steel sheath can be pressed and installed through the cooperation of jacking of the pressure jacking machine and the limiting device. Meanwhile, the limiting device is provided with a plurality of sets of limiting holes with different heights, adjustment can be conducted according to the construction height of thesplicing sleeve, and more labor is saved in use. The whole support can be conveniently moved through the moving assembly, meanwhile, the whole support can be fixed in the mode that a conical tip is inserted into the ground, and the whole support is prevented from moving in the pressing process.

Description

technical field [0001] The invention relates to the technical field of power supply construction equipment, in particular to a large cross-section wire connecting pipe steel sheath support and a construction method. Background technique [0002] Conductor splicing has always been an extremely important link in the wiring construction stage of transmission line engineering. Both the construction efficiency and splicing quality of conductor splicing must be effectively guaranteed. Therefore, the protection of the steel sheath to the connecting pipe is a crucial link in the wiring construction. [0003] More commonly used is 1250mm 2 Large cross-section wire connection tube, the matching steel sheath model is: SJ1-Φ80*1050 / 43, each set has a diameter of 11.5cm, a length of 2.3 meters, and a weight of 72kg. This type of steel sheath protection device is large in size and heavy in weight, and there are snake joint ends at both ends of the steel sheath, and 20 M10*35 hexagon soc...

AI Technical Summary

Problems solved by technology

This type of steel sheath protection device is large in size and heavy in weight, and there are snake joint ends at both ends of the steel sheath, and 20 M10*35 hexagon socket head bolts need to be fastened on the snake joint ends to complete the packaging. There is a big difference in the direct packaging of the steel sheath with iron wires. During the construction process, the installation time of the steel sheath greatly occupies the total time for connecting the wires. Installing the snake heads at both ends, the installation efficiency of the steel sheath is extremely low, and the compression effect is not good, which is prone to misalignment. Once the steel sheath is not installed firmly, it may cause the steel sheath to fall off during the wire deployment process, which not only affects The construction progress also caused the construction personnel to climb the tower twice, increasing the construction risk. At the same time, since the construction site is all land, the ground is soft, which is not conducive to the implementation of the compaction operation.
