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.

Embodiment 1

[0030] A large cross-section wire connecting tubular steel sheath bracket, comprising a bracket 2 and a pressure jack 11, the bracket 2 is provided with a pressure jack 11, the pressure jack 11 is a SQD type loose clamp jack, the pressure The jacking machine is composed of an upper chuck, an oil cylinder, a lower chuck and an operating rod. The heavy object can be lifted step by step to a specified height through the operating rod. The SQD type loose clamp jack is stable, safe and reliable, and has an adjustable (micro-drop) function. The lifting height can be controlled more precisely. When the steel sheath is assembled, it can effectively control the lamination gap, making the fastening and alignment more accurate. Accurate, improve bolt tightening efficiency. The upper end of the pressure jacking machine 11 is connected to a fastening device, and a limit device is provided outside the fastening device. The lower end of the limit device is connected to the support 2, and the...

Embodiment 2

[0032] A kind of construction method of a kind of large cross-section wire connecting tubular steel sheath support according to the structure of embodiment 1, concrete steps are as follows:

[0033] (1) Move the bracket 2 to the working position through the universal wheel 8 in the moving assembly, rotate the fastening nut 7, adjust the position of the bottom end of the fixing screw 1 to be lower than the bottom end of the universal wheel 8, until it is inserted into the soil, so that the whole The device is fixed here;

[0034] (2) put the steel sheath on the connecting pipe outside, put the steel sheath connecting pipe into the non-closed annular tube formed by the bottom support 9 and the top cover 10;

[0035] (3) Limit the height of the fastening device through the limit device; determine the required height, select the limit hole 4 with a suitable height, and pass the limit rod 5 through the first limit plate 3 and the second limit plate 6 Symmetry The limit hole 4; the...

Abstract

The invention provides a large cross-section wire connecting tube steel sheath bracket, and provides a construction method, including a bracket and a pressure jacking machine, the bracket is provided with a 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 limit device, the lower end of the limit device is connected with the bracket, and the lower end of the bracket is connected with the moving component. The fastening device can fix the connecting pipe with the steel sheath without manual fixing. Through the cooperation of the pressure jacking machine and the limit device, the steel sheath can be pressed and installed. At the same time, the limit device has multiple settings. A set of limit holes with different heights can be adjusted according to the construction height of the connecting pipe, which is more labor-saving. The whole bracket can be easily moved by moving the components, and the whole bracket can be fixed by inserting the tapered tip into the ground to prevent it Move during compaction.

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...
