Embodiment Construction
[0081] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0082] A square tool to improve the safety of the steering block of the tower assembly,
[0083] Including the main body 1 and multiple ears 2, the main body is a square frame structure made of steel pipes welded end to end. The outer diameter of the main steel pipe is 60mm, the inner diameter is 48mm, and the wall thickness is 6mm. Ears are installed at the four corners of the main body and the center of the four-frame frame. , each side is long and the middle ear faces obliquely upward at a 45-degree angle;
[0084] The four corners of the main body are made of arc corner transition to improve safety;
[0085] In order to facilitate adjustment, one ear is installed on both sides of the ear install...

The invention relates to a square tool capable of increasing the safety of a direction sliding vehicle for tower building, comprising a main body and a plurality of ears, wherein the main body is a square frame structure welded by the front-to-end welding of steel pipes, and the four corners of the main body and the center of the four-edge frame body are provided with ears with the ears of every two edges are arranged upwardly with a 45-degree angle in an inclined manner. The four corners of the main body are fabricated as arc angles for transition. The two sides of the ear mounted in the center of the four-edge frame body are provided with an ear each. The square tool of the invention is portable and easy to operate and can increase the working efficiency. Reliable in quality, the square tool ensures the construction safety. Subjected to stable force, the square tool ensures the construction quality. With the square tool, remarkable economic and social gains can be obtained, therefore, making the square tool with wide prospects for promotion.
Description
technical field [0001] The invention belongs to the field of electric power safety monitoring equipment, in particular to a square tool for improving the safety of a steering block in a tower assembly. Background technique [0002] Yuheng-Weifang 1000 kV UHV AC transmission and transformation project line project (6 tenders) is located in Shanxi Province. The line is erected with two single circuits. The total length of the single circuit line is 78.979km. The proportion of terrain: 35% is mountainous. 65% are no-man's land in high mountains and ridges. There are 155 bases in total on the whole line, including 33 bases of strain towers and 122 bases of linear towers, all of which are angle steel towers. [0003] At present, during the tower assembly process of the transmission line, the steering block is generally connected to a force-bearing system composed of shackles, and then respectively fixed on the construction holes of the four tower legs. During the construction p...
