[0038] Example 1

[0039] Reference Attachment Figure 1-4 The present embodiment provides a device for facilitating the anti-corrosion operation of steel pipes, which includes a support frame 1 and a reversing member 2. The support frame 1 is used to support the steel pipe 3 to be subjected to the anti-corrosion operation. It includes two groups of relatively arranged bases 1-1. The top of each base 1-1 is provided with a detachable pipe support 1-2. The two pipe supports 1-2 are coaxially distributed and are respectively used to support the two ends of the steel pipe 3; the reversing member 2 is used to clamp the steel pipe 3 supported by the support frame 1, so that the steel pipe 3 rotates around its own axis, so as to facilitate the workers to apply asphalt paint and wrap glass fiber cloth on the steel pipe 3. The reversing member 2 includes a clamping arm 2-1 and a handle 2-2. The clamping arm 2-1 and the handle 2-2 are arranged in parallel and are connected by a connecting rod 2-3. The end of the clamping arm 2-1 away from the connecting rod 2-3 is provided with a U-shaped groove 2-4 whose width is set according to the wall thickness of the steel pipe 3, and the inner wall of the U-shaped groove 2-4 is provided with an anti-slip pad 2-5.

[0040] During construction, the two ends of the steel pipe 3 to be anti-corrosion are placed on the pipe support 1-2 so that it is firmly supported. Then the worker clamps the U-shaped slot 2-4 of the clamping arm 2-1 with the pipe wall of the steel pipe 3 and rotates the handle 2-2 to drive the steel pipe 3 to rotate. The worker who applies asphalt paint and wraps fiberglass cloth stands between the two bases 1-1 to carry out construction on the rotating steel pipe 3.

[0041] In this embodiment, the heavy steel pipe 3 is supported by the support frame 1, and the steel pipe 3 is rotated by the reversing member 2, which reduces the labor intensity of workers, improves the anti-corrosion construction efficiency, and reduces the construction safety risk.

[0042] The above-mentioned base 1-1 includes a horizontal support rod 1-11, a vertical support rod 1-12 and a diagonal support rod 1-13. A plurality of horizontal support rods 1-11 are staggered and connected to form a bottom support network of the vertical support rod 1-12. The two ends of the diagonal support rod 1-13 are respectively connected to the horizontal support rod 1-11 and the vertical support rod 1-12 to form a triangular stable structure. The structural stability of the entire base 1-1 and its support stability for the steel pipe 3 are improved through the diagonal support rod 1-13.

[0043] A mounting plate 1-3 is provided at the top of the vertical support rod 1-12. The mounting plate 1-3 is located on both sides of the pipe support 1-2 and is connected to the outer side wall of the pipe support 1-2 by bolts. The two side walls of the pipe support 1-2 are limited by the mounting plate 1-3 and are fastened twice by bolts, which is convenient for installation and disassembly and has high connection stability.

[0044] A rotating sleeve 2-6 is sleeved on the handle 2-2, and a limit block 2-7 is provided on both sides of the axis of the rotating sleeve 2-6. The limit block 2-7 is fixedly connected to the handle 2-2. The rotating sleeve 2-6 can rotate around the axis of the handle 2-2, so that the worker can save effort when rotating the handle 2-2 to drive the steel pipe 3 to rotate. The limit block 2-7 can prevent the rotating sleeve 2-6 from slipping, making the device structure more stable.

[0045] Example 2

[0046] Reference Attachment Figure 5-8 , the difference from Example 1 is that the clamping arm 2-1 in this embodiment includes correspondingly arranged clamping rod 1 4 and clamping rod 2 5, the connecting rod 2-3 is located on the same side of the two, the side walls of clamping rod 1 4, connecting rod 2-3 and clamping rod 2 5 are connected in sequence to form a U-shaped slot 2-4, clamping rod 1 4 is fixedly connected to connecting rod 2-3, clamping rod 2 5 can be moved along the connecting rod 2-3 to approach or move away from clamping rod 1 4, and by adjusting the distance between clamping rod 1 4 and clamping rod 2 5, the width of the U-shaped slot 2-4 can be changed to adapt to steel pipes 3 with different wall thicknesses.

[0047] Specifically, a chute 2-31 is provided in the connecting rod 2-3. A rotatable screw 6 is disposed in the chute 2-31. A threaded slider 7 is sleeved on the screw 6 and slidably connected to the chute 2-31. The second clamping rod 5 is located outside the chute 2-31 and fixedly connected to the threaded slider 7. Because the chute 2-31 restricts the sidewall of the threaded slider 7, the threaded slider 7 can slide within the chute 2-31 when the screw 6 is rotated, thereby driving the second clamping rod 5 to smoothly move toward or away from the first clamping rod 4.

[0048] In order to improve the clamping stability of the steel pipe 3 and prevent the clamping plate 1 and the clamping plate 2 from being too long, causing the ends of the two to be away from the connecting rod 2-3 to warp outward in opposite directions, this embodiment provides a locking bolt 8 on the clamping rod 2 5 arranged in the same direction as the connecting rod 2-3, and the other end of the locking bolt 8 is connected to the clamping rod 1 4.

[0049] When the distance between the clamping rod 1 4 and the clamping rod 2 5 needs to be adjusted, the locking bolt 8 is first loosened, and then the screw rod 6 is rotated to allow the threaded slider 7 to drive the clamping rod 2 5 to move. After moving into place, the locking bolt 8 is fixed.

[0050] In order to prevent the screw 6 from being accidentally touched and causing the clamping rod 2 5 to loosen, this embodiment provides an embedded rotating block 9 on the end of the connecting rod 2-3 away from the clamping rod 1 4. One end of the rotating block 9 is fixedly connected to the screw 6, and the other end is provided with a hexagonal groove 10, which can be used with a hexagonal wrench.

[0051] The method for using the device includes the following steps:

[0052] (1) Arrange the mounting frame and adjust the distance between the two bases 1-1 according to the length of the steel pipe 3;

[0053] (2) Use lifting equipment to lift the steel pipe 3 onto the pipe support 1-2 and place it stably;

[0054] (3) The U-shaped slot 2-4 on the clamp arm 2-1 is clamped and fastened to the pipe wall at one end of the steel pipe 3, and the handle 2-2 is rotated to drive the steel pipe 3 to rotate around its own axis. The worker can then perform anti-corrosion work on the rotating steel pipe 3.

[0055] Compared with the prior art, the beneficial effects of the present invention are: by supporting the heavy steel pipe 3 through the support frame 1 and using the reversing member 2 to rotate the steel pipe 3, the labor intensity of workers is reduced, the anti-corrosion construction efficiency is improved, and the construction safety risk is reduced; the U-shaped slot 2-4 of the clamping arm 2-1 is set to a width-adjustable form, which improves the scope of application of the device.

[0056] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
