Problems solved by technology

However, for this large-diameter pipe, its inner diameter is 3.5 meters and its outer diameter is 3.9 meters. Due to its large diameter, large volume, and heavy weight, when it is also lifted with a horizontal bracket, due to the effect of gravity, the pipe will be damaged. Ellipse, that is, the direction of the pipe section is no longer a regular circle
For an irregular circle, it is difficult to fit the pipe tightly with the corresponding dust

Embodiment Construction

[0011] In order to further illustrate the present invention, the following preferred embodiments are described in detail in conjunction with the accompanying drawings as follows:

[0012] see figure 1 and figure 2 , which is a structural schematic diagram of a large-diameter pipe assembly and lifting tool 100 provided in the first embodiment of the present invention. The large-diameter pipe assembly and lifting tool 100 includes two arc-shaped clamping parts 11 and two lifting parts 12 for connecting the two clamping parts 11 .

[0013] The two arc-shaped clasping members 11 have the same structure, and here, only one of them is taken as an example to illustrate its structure and working principle. The clasping member 11 can be integrally formed of metal materials, such as steel and the like. The arc radius of the clamping member 11 is equal to the radius of the pipe, so that the pipe can be tightly held when the pipe is hoisted. The sidewalls at both ends of the clamping...

Abstract

Provided is a large-diameter tube assembling and lifting tool. The large-diameter tube assembling and lifting tool comprises two arc-shaped inclasping pieces and two lifting pieces used for connecting the at least two arc-shaped inclasping pieces. The arc radiuses of the arc-shaped inclasping pieces are equal to the radius of a tube. The two lifting pieces are arranged on the extension line of the diameter of the tube, and a lifting hole is formed in each lifting piece. The lifting holes are used for connecting a lifting rope in a penetrating mode. Due to the fact that a circular ring is used to lift the large-diameter tube, gravity stressed by the large-diameter tube assembling and lifting tool can be evenly distributed on the circular ring, and therefore pressure on each portion of the tube is roughly equal. Thus, the phenomenon that circular degrees of the tube are reduced caused by uneven stress in the process of lifting can be avoided.

Description

technical field [0001] The invention relates to a hoisting device for UHV power transmission equipment, in particular to a hoisting tool for assembling large-diameter pipes. Background technique [0002] With the development of the power industry, especially the needs of UHV power transmission and transformation, the demand for bushings is also increasing. Usually, the hollow insulators of bushings used outdoors are porcelain insulators. Due to the poor pollution flashover resistance of porcelain insulators, the quality is difficult to control, and they are easily broken during transportation and installation, and they need to be cleaned regularly during use. It has brought a lot of inconvenience. To solve these problems, the power equipment industry has developed large-diameter hollow composite insulators. [0003] This large diameter hollow composite insulator consists of a large diameter pipe with two flanges fitted to the pipe. For pipes with regular diameters, they c...
