Oblique angle cutting equipment for rectangular square pipe of electric power iron tower

Abstract

The invention relates to oblique angle cutting equipment for a rectangular square pipe of an electric power iron tower. The oblique angle cutting equipment comprises a workbench, a clamping and rotating mechanism and a fixing and cutting mechanism, wherein the workbench is arranged on the working ground; and the clamping and rotating mechanism is arranged at the rear end of the workbench, and thefixing and cutting mechanism is arranged on the upper end face of the workbench. According to the oblique angle cutting equipment for the rectangular square pipe of the electric power iron tower, theadopted clamping and rotating mechanism can solve the rotating problem of the rectangular square pipe, the rectangular square pipe is fixed in the clamping and rotating mechanism, and then the required angle is adjusted and rotated, so that the cutting positions of the rectangular square pipe are the same; the left side and the right side of the rectangular square pipe are fixed through the fixingand cutting mechanism, and the rectangular square pipe is cut through obliquely-arranged cutting blades, so that the cutting positions of the rectangular square pipe are the same; and electric air cylinders two push oblique clamping plates to clamp the front end of the rectangular square pipe, so that the rectangular square pipe is prone to rotate in the rotating process, and meanwhile the oblique clamping plates do not influence cutting of the rectangular square pipe by the cutting blades.

Description

technical field [0001] The invention relates to the technical field of cutting, in particular to a bevel cutting device for a rectangular square tube of a power tower. Background technique [0002] Power towers generally refer to transmission line towers. Transmission line towers are tower-shaped buildings for power transmission. Their structural characteristics are that various tower types are space truss structures. The rods are mainly composed of single equilateral angle steel or combined angle steel. Generally, two types of Q235 (A3F) and Q345 (16Mn) are used. The connection between the rods is made of rough bolts, which are connected by bolts under shear force. The whole tower is composed of angle steel, connecting steel plates and bolts. The steel plates are welded into an assembly, so hot-dip galvanized anti-corrosion, transportation and construction erection are extremely convenient. For iron towers with a height below 60m, foot nails are set on one of the main mater...

AI Technical Summary

Problems solved by technology

[0003] 1. The rectangular square tube of the traditional power tower is easy to cut when it is obliquely cut. In the later use process, corresponding welding adjustments need to be made according to the required cutting position, which makes the workflow cumbersome;

[0004] 2. When the rectangular square tube is cut at an oblique angle, the rectangular square tube is placed straight, which makes it difficult for the cutting blade to cut the rectangular steel tube, which makes the cutting shape inconsistent, resulting in the inability to connect the rectangular square tube incorrectly.
