Strain tower column module for emergency repair of ultra-high-voltage power transmission line

Abstract

The invention discloses a strain tower column module for emergency repair of an ultra-high-voltage power transmission line. The strain tower column module is used for temporarily combining and constructing an emergency repair tower for the ultra-high-voltage power transmission line, is in a rectangular frame shape and is manufactured integrally by three three-dimensional square strain tower column units, wherein four hollow cylinders are arranged at four corners of the rectangle to bear vertical load of the strain tower for emergency repair; 12-24 mounting holes are formed in the upper end surface and the lower end surface of the strain tower column module and used for fixing the strain tower column module for straight combination and mounting, and four guiding and locating pins are arranged at four corners of the upper end surface of the strain tower column module and used for guiding and locating the strain tower column module for straight combination and mounting. The strain tower column module can be manufactured integrally instead of combination after split manufacture, so that the efficiency is increased, the cost is reduced, and the strain tower column module is convenient to use. The strain tower column module is resistant to axial pressure and tension, large in bending moment and shear force, light and convenient to carry and low in manufacture cost and adopts a simple construction technology.

Description

technical field [0001] The present invention relates to emergency repair equipment for power transmission lines. Specifically, the present invention relates to emergency repair equipment for tension poles and towers of ultra-high voltage transmission lines. More specifically, the present invention relates to a tension tower column module for emergency repair of tension poles and towers for ultra-high voltage transmission lines . Background technique [0002] When transmission lines, such as ultra-high voltage transmission lines of 220kv or above, encounter extreme natural disasters such as violent storms, earthquakes, rain disasters, snow disasters, and earthquakes, the towers of ultra-high voltage transmission lines often collapse. As a result, the high-voltage transmission line section of the collapsed iron tower and its support will endanger its nearby traffic facilities, such as highways, railways and other facilities, as well as various civil facilities and production e...

Problems solved by technology

[0007] However, according to this technical scheme, the four uprights of the unit body are outer cylinders, and the inside of the cylinder is hollow; the width of the crosspiece of the unit body is much smaller than the width of the upright column; the connecting holes of the unit body are located inside the four corners; the structural strength is not enough, and it is necessary to add holes position connection plate; and because of the hole position connection plate, the internal mold cannot be dislodged, and multiple one-piece manufacturing cannot be done at one time. Instead, it is combined after split-type manufacturing, which affects efficiency and cost, and is inconvenient to use

[0008] Therefore, the strength of the combined high-voltage line iron tower column-type emergency repair tower unit body involved in the technical solution of the above patent application is insufficient, and it is difficult to bear the lateral load on the side of the iron tower cross arm. Difficult to apply to the emergency repair of tension poles and towers with high requirements on the cross-arm side line load
