Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of for sandblasting surface treatment pipeline fixing device. BACKGROUND

[0002] Sandblasting surface treatment is an important step of pipeline processing, which aims to remove dirt, scale, rust and other impurities on the surface of the pipeline to improve the appearance and quality of the product. During manual sandblasting surface treatment operation, the pipeline is often placed on a mobile flatcar. The pipeline may roll due to high-speed impact of the blasting material, resulting in instability of the pipeline body. In the existing operation process, the triangular wedge is often placed at the bottom of the pipeline to fix it. However, due to the simple frame structure of the mobile work platform, the placement position is limited and there are safety hazards during the process. Additionally, the pipeline body may shake due to impact during the operation process, which may cause the triangular wedge to shift, posing a significant operational risk. SUMMARY

[0018] Referring to Figures 1-4 , a pipe fixing device for sand blasting surface treatment, which comprises two pipe clamps 1, the two pipe clamps are fixed by a long screw rod 7, and the two pipe clamps clamp two pipelines respectively, and the two pipelines are fixed by the long screw rod after clamping to form an integral structure, so that the pipelines are prevented from rotating due to high-speed impact of materials, and the stability of sand blasting surface treatment quality is ensured, the pipe clamp comprises a U-shaped frame 2, both ends of the U-shaped frame are fixed with bearing sleeves 9, the bearing sleeves are connected with screw sleeves 3 through bearings, both ends of the screw sleeves are threadedly connected with screw rods 5, the screw rods are opposite in screw direction, and the end of the screw rod is fixed with an abutting plate 6 after penetrating through a through hole 10 of the U-shaped frame.

[0019] The pipe fixing device for sand blasting surface treatment, the abutting plate is a forked plate.

[0020] The pipe fixing device for sand blasting surface treatment, a guide rod 4 is fixed on the abutting plate, and the guide rod penetrates through a round hole of the U-shaped frame.

[0021] Working principle: in use, referring to Figures 5-6 , first, clamp two pipelines by two pipe clamps respectively;

[0022] The method for clamping the pipe clamp is that the screw sleeve is fixed with a nut, the nut is twisted by hand to rotate the screw sleeve, the screw sleeve has internal threads at both ends matched with the corresponding side screw rods, the external threads of the two screw rods are opposite in direction, the two screw rods can move synchronously and reversely when the screw sleeve rotates, and the abutting plate abuts against the inner wall of the pipe until the abutting plate abuts against the inner wall of the pipe;

[0023] After the two pipe clamps are clamped on the pipe 11, the long screw rod is inserted through the two U-shaped frames, eight nuts are threadedly connected on the long screw rod and are distributed at both ends of the U-shaped frames, and the nuts are tightened to abut against the U-shaped frames, so that the long screw rod connects the two pipe clamps into a whole structure, prevents the pipe from rotating due to high-speed impact of the material, and ensures the stability of the sandblasting surface treatment quality.
