The second fixing member 42 is mounted on a side wall of the shielding plate 3 remote from the adjusting nut 2, and the second fixing member 42 is slidably connected to an outer circumferential side of the threaded rod 1. The limiting spring 43 is disposed between the first fixing member 41 and the second fixing member 42, and two ends of the limiting spring 43 are respectively abutted against the first fixing member 41 and the second fixing member 42, when the protection tool is not used, the limiting spring 43 can fix the second fixing member 42 and the protection plate 3 at a certain position, and cannot move along the threaded rod 1 at will.

The first fixing member 41 includes a first connection ring 411 and a first mounting plate 412 welded to an outer wall of the first connection ring 411, and similarly, the second fixing member 42 includes a second connection ring 421 and a second mounting plate 422 welded to an outer wall of the second connection ring 421, and the first mounting plate 412 and the second mounting plate 422 are in one-to-one correspondence and are in the same plane. The supporting member 44 includes a first supporting rod 441, a second supporting rod 442 and a tightening block 443, wherein one end of the first supporting rod 441 is hinged to the first mounting plate 412, the other end of the first supporting rod 441 is hinged to the tightening block 443, and likewise, one end of the second supporting rod 442 is hinged to the second mounting plate 422, and the other end of the second supporting rod 442 is hinged to the tightening block 443, and the geometric center lines of the first supporting rod 441 and the second supporting rod 442 are in the same plane. It should be noted that, at least two supporting members 44 are provided, and the supporting members 44 are in one-to-one correspondence with the first mounting plates 412, and in this embodiment, three supporting members 44, the first mounting plates 412, the second mounting plates 422, and the supporting members 412 are provided. When the protection tool is not used, the limiting spring 43 is in a normal state, and the included angle between the first supporting rod 441 and the second supporting rod 442 is greater than 120 ° and less than 180 °.

When the protection tool is used for protecting the flange sealing surface, the support assembly 4 is inserted into the pipeline until the protection plate 3 is abutted against the flange sealing surface, the protection plate 3 is fixed, the adjusting nut 2 is rotated, the threaded rod 1 drives the first fixing piece 41 to move towards the direction close to the adjusting nut 2, meanwhile, the first support rod 441 and the second support rod 442 rotate, the abutting block 443 is pushed towards the direction far away from the threaded rod 1, and the abutting block can abut against the inner wall of the pipeline, so that the protection tool is fixed. In this process, the first support rod 441 and the second support rod 442 may rotate to the opposite side of the preset direction, so that the abutting block 443 moves to the direction close to the threaded rod 1, and the protection tool is disabled, so that the long limiting strip 4431 is welded to the side of the abutting block 443 away from the threaded rod 1 along the vertical direction, and part of the side walls of the first support rod 441 and the second support rod 442 are attached to part of the side walls of the limiting strip 4431, so that the first support rod 441 and the second support rod 442 cannot rotate to the side close to the threaded rod 1, and the possibility of the protection tool being disabled is reduced.

In addition, since the protection plate 3 needs to bear the impact force of sand blasting or paint spraying, the protection plate 3 is made of a material with high hardness, but in the use process, the protection plate 3 needs to be abutted against the sealing surface of the flange, and the sealing surface of the flange may be damaged. Therefore, the side wall of the protection plate 3 close to the second fixing piece 42 is also adhered with the protection pad 31 made of rubber, and the possibility that the flange sealing surface is damaged due to abutting with the protection plate 3 is reduced. More preferably, the handle 8 is welded at one end of the adjusting nut 2 far away from the protection plate 3, the geometric center line of the handle 8 is perpendicular to the geometric center line of the adjusting nut 2, and an operator can drive the adjusting nut 2 to rotate by rotating the handle 8, so that the operation is more convenient and labor-saving.

The implementation principle of the flange sealing surface protection tool for sand blasting and paint spraying in the embodiment of the application is as follows: before the pipeline is required to be sandblasted or sprayed, an operator holds the handle 8, inserts the support assembly 4 into the pipeline, enables the protection pad 31 to be attached to the flange sealing surface, enables the protection plate 3 to be abutted against the flange sealing surface by using a palm or other tools, enables the protection plate 3 to be unable to rotate, rotates the handle 8 at the moment, synchronously rotates the adjusting nut 2, and along with the rotation of the adjusting nut 2, the threaded rod 1 moves towards the direction close to the adjusting nut 2, the distance between the first fixing piece 41 and the second fixing piece 42 is shortened, the first supporting rod 441 and the second supporting rod 442 rotate, and the abutting block 443 moves towards the direction far away from the threaded rod 1 until abutting against the inner wall of the pipeline, and the protection tool is fixed on the pipeline at the moment, so that the pipeline can be sandblasted or sprayed; after the sand blasting or paint spraying is finished, the handle 8 is reversely rotated, and when the abutting block 443 is not abutted against the inner wall of the pipeline, the protection tool can be taken down. The protection tool can be repeatedly utilized, the construction cost is reduced, the operation process is simple and labor-saving, the working efficiency is improved, and the construction period is shortened.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
