Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to a steel pipe for a steel pipe tower with a firm structure. Background Art

[0002] The main parts of the steel tube tower are steel tubes, and the other parts are steel tubes or steel sections. It is a lattice tower composed of overhead transmission lines to support conductors and lightning conductors. It can ensure that the conductors meet the distance requirements to the ground and objects, and can withstand the loads of the conductors, lightning conductors, and themselves, as well as external loads.

[0003] Existing steel pipe towers usually use four pipe bodies, and transverse tie rods and diagonal tie rods are arranged between the pipe bodies to connect the four pipe bodies to increase the structural stability. A connecting plate is usually also arranged on the pipe body, and an angle steel is arranged on the connecting plate, and the angle steel is used to fix the transverse tie rod and the diagonal tie rod. However, due to the existence of errors in reality, the tension on the transverse tie rods and the diagonal tie rods between the four pipe bodies cannot be completely uniform during installation. The transverse tie rods and the diagonal tie rods that are subjected to greater tension have a reverse tension on the connecting plate, which will easily cause a tendency to detach from the pipe body when used for a long time, which is dangerous to a certain extent.

DETAILED DESCRIPTION

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] A steel pipe for a steel pipe tower with a firm structure comprises an upper end face 1 and a lower end face 2, wherein a pipe body 3 is arranged between the upper end face 1 and the lower end face 2.

[0019] A connecting piece 8 is welded on the pipe body 3. The connecting piece 8 is provided with a plurality of through holes 9 for fixing the angle steel, and fixing the transverse tie rod and the diagonal tie rod through the angle steel. Preferably, three groups of connecting pieces 8 arranged vertically are provided on each pipe body 3, and each group of connecting pieces 8 is divided into two left and right pieces, and the two connecting pieces 8 are usually arranged at 90 degrees.

[0020] Each group of connecting pieces 8 is welded with arc pieces 6 at the upper and lower positions. Among them, a plurality of through holes 4 are horizontally arranged on the tube body 3, and welding columns 5 corresponding to the through holes 4 are arranged on the inner side of the arc pieces 6. The welding columns 5 penetrate into the through holes 4 and form welding points 7 by welding, thereby realizing the connection between the arc pieces 6 and the tube body 3.

[0021] The connecting piece 8 is welded to the arc-shaped piece 6 , and the connecting piece 8 is welded to the tube body 3 at the same time.

[0022] A transverse groove 10 is provided in the middle of the connecting piece 8. A support 11 is welded on the tube body 3, the support 11 passes through the transverse groove 10, and a welding point 7 is provided between the support 11 and the transverse groove 10 to connect the support 11 and the connecting piece 8.

[0023] An arc-shaped notch 12 is provided below the support 11, and the arc-shaped notch 12 forms two "feet" on the left and right at the lower end of the support 11. The tube body 3 is provided with a plurality of vertical grooves 13, and the lower "feet" on both sides of the arc-shaped notch 12 on the support 11 are provided with strips 14 corresponding to the vertical grooves 13. The strips 14 are bent and extend into the vertical grooves 13, and are connected and fixed by welding. Among them, the length of the strips 14 is longer than that of the vertical grooves 13, so that the strips 14 themselves can be hooked in the tube body 3, further improving stability.

[0024] When connecting the support 11 and the connecting piece 8, the support 11 needs to be passed through the transverse groove 10 on the connecting piece 8 first, and then the strip piece 14 is bent into the vertical groove 13 to ensure that the support 11 and the connecting piece 8 can be installed smoothly.

[0025] The tube body 3 is provided with insertion holes 15 on both sides of the arc-shaped piece 6, and the insertion holes 15 are welded with fixing columns 16, and a hook body 17 is provided outside the fixing column 16. A lock buckle 18 is provided on the arc-shaped piece 6, and the lock buckle 18 is hooked on the hook body 17. This arrangement can ensure that when the arc-shaped piece 6 has a tendency to be separated after long-term use, the lock buckle 18 can firmly grasp the hook body 17 to reduce the risk of separation.

[0026] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
