Technical Field
[0001] The utility model relates to the technical field of special-shaped steel pipes, and particularly relates to a bending-resistant special-shaped steel pipe. Background Technique
[0002] Special-shaped steel pipes are the general name for seamless steel pipes with cross-sectional shapes other than circular pipes. According to different cross-sectional shapes and sizes of the steel pipes, they can be further divided into special-shaped seamless steel pipes with equal wall thickness (code name D), special-shaped seamless steel pipes with unequal wall thickness (code name BD), and special-shaped seamless steel pipes with variable diameter (code name BJ). They are economic section steel pipes, including those with non-circular cross-sectional contours, equal wall thickness, variable wall thickness, variable diameter and variable wall thickness along the length direction, symmetrical and asymmetrical cross-sections, such as square, rectangular, conical, trapezoidal, spiral, etc.
[0003] Patent No. CN214392984U discloses a collision-resistant special-shaped steel pipe, which relates to the technical field of steel pipes. It includes a pipe body and a positioning device. The positioning device is arranged on the inner wall of the pipe body. The positioning device includes a positioning sleeve, and the positioning sleeve is slidably connected to the inner wall of the pipe body. The inner wall of the pipe body is fixedly connected with a mounting rod. The upper surface of the mounting rod is rotatably connected with two symmetrically arranged active rods. One end of the active rod away from the mounting rod is rotatably connected with a stabilizing block, and one end of the stabilizing block away from the active rod is rotatably connected with a driven rod. In the present utility model, most existing steel pipes are positioned and welded by manual holding at present, but it is difficult to ensure that the steel pipes are in a stable state and are prone to shaking, resulting in deviations at the welding points, making it impossible to stably weld and fix the steel pipes, causing a large waste of resources and being unfavorable for the stable use of the equipment. The application of this device effectively avoids the above problems and improves the stability of the equipment.
[0004] Existing special-shaped steel pipes have the following disadvantages: 1. The strength of special-shaped steel pipes is low, and after being stressed in the middle, the bending resistance effect is not obvious. For this reason, we propose a bending-resistant special-shaped steel pipe. Summary of the Invention
[0005] The main purpose of the present utility model is to provide a bending-resistant special-shaped steel pipe, which can effectively solve the problems in the background technique.
[0006] To achieve the above purpose, the technical solution adopted by the present utility model is as follows:
[0007] A bending-resistant special-shaped steel pipe includes a special-shaped steel pipe main body, a strip seat, a reinforcing rod, and a triangular brace. Embedding grooves are provided at both ends of the inner bottom of the special-shaped steel pipe main body, and strip seats that play an overall bending resistance role are embedded in the embedding grooves. The strip seats are installed with reinforcing rods with a strengthening function through installation holes, and triangular braces are welded at equal intervals at both ends of the inner top of the special-shaped steel pipe main body.
[0008] Furthermore, an anti-corrosion coating is provided on the outer surface layer of the special-shaped steel pipe body, and the anti-corrosion coating is specifically a galvanized layer. By using the galvanized layer as the anti-corrosion coating, the anti-corrosion performance of the special-shaped steel pipe body is improved. The coating has high strength, is not easy to peel off, and is durable.
[0009] Furthermore, lateral weight-reducing holes are arranged on both sides of the special-shaped steel pipe body. The material is easy to obtain, has high strength, is not easy to damage, and is durable.
[0010] Furthermore, the special-shaped steel pipe body is specifically made of iron material.
[0011] Furthermore, the chamfers at the four sides of the special-shaped steel pipe body are arc-shaped.
[0012] Compared with the prior art, the present utility model has the following beneficial effects:
[0013] 1. For the anti-bending special-shaped steel pipe of the present utility model, by using the strip-shaped seats embedded in the embedding grooves and the reinforcing rods arranged at equal distances between the strip-shaped seats, the anti-bending performance of the special-shaped steel pipe body is greatly improved, avoiding the bending of the middle part of the special-shaped steel pipe body under stress, effectively extending the service life of the special-shaped steel pipe body, and the triangular braces on both sides of the top end inside the special-shaped steel pipe body further improve the strength, stiffness and stability of the special-shaped steel pipe body.
[0014] 2.

By using the anti-corrosion coating which is specifically a galvanized layer, the anti-corrosion performance of the special-shaped steel pipe body is improved. The coating has high strength, is not easy to peel off, and is durable. BRIEF DESCRIPTION OF THE DRAWINGS
