[0027] Based on the background technology, rust removal of hydraulic corrosion equipment parts mainly relies on manual polishing with brushes and sandpaper. The rust removal and polishing work is large, the rust removal efficiency is low, the rust removal effect is average, and it affects the fit of threads and screw holes, damages threads, affects maintenance quality and air supply, and poses a safety hazard to maintenance.

[0028] In order to solve the above technical problems, Figure 1 As shown, the utility model provides a hole rust removal tool, comprising:

[0029] A height adjustment rod 1 is connected to the up-and-down moving rotating tool, and the height adjustment rod 1 includes a height fixing sub-rod 11 and a height adjustment sub-rod 12, and the height fixing sub-rod 11 and the height adjustment sub-rod 12 are connected by pulling;

[0030] The width adjustment rod 2 comprises a width fixing sub-rod 21 and width adjustment sub-rods 22 arranged at both ends of the width fixing sub-rod 21, wherein the width fixing sub-rod 21 is fixed to the end of the height fixing sub-rod 11, and the width adjustment sub-rod 22 and the width fixing sub-rod 21 are adjustable;

[0031] The brush head is detachably arranged at the end of the width adjustment sub-rod 22 and can abut against the inner wall of the hole 6 .

[0032] Specifically, the rotating tool that moves up and down can be a magnetic drill, or other tools that can move up and down and rotate. The height adjustment sub-rod 12 of the height adjustment rod 1 is fixedly connected to the drill bit of the magnetic drill. The height fixing sub-rod 11 and the height adjustment sub-rod 12 of the height adjustment rod 1 are pull-out settings, which can also be understood as the height adjustment sub-rod 12 being sleeved on the outer wall of the height fixing sub-rod 11. According to the depth of the hole 6, the height adjustment sub-rod 12 is pulled out to increase the length of the height adjustment sub-rod 12 and the height fixing sub-rod 11, or the height adjustment sub-rod 12 is pushed and pulled to reduce the distance between the height adjustment sub-rod 12 and the height fixing sub-rod 11, thereby shortening the height adjustment rod 1. In this way, the length adjustment of the height adjustment rod 1 can be achieved, and it can be suitable for holes 6 of different depths. The width fixing rod of the width adjusting sub-rod 22 is connected to the end of the height fixing sub-rod 11, and the width adjusting sub-rod 22 is adjustably arranged at both ends of the width fixing sub-rod 21. According to the diameter of the hole 6, the length of the width adjusting sub-rod 22 and the width fixing sub-rod 21 can be adjusted, and it can be suitable for holes 6 of different diameters. The brush head is detachably arranged at the end of the width adjusting sub-rod 22. After adjusting the length of the width adjusting sub-rod 22 and the width fixing sub-rod 21 according to holes 6 of different diameters (exemplarily, bolt holes), the brush head can be abutted against the inner wall of the hole 6, and the height adjusting rod 1 is driven to rotate when the rotating tool is moved up and down, and the height adjusting rod 1 drives the width adjusting rod 2 to rotate, thereby driving the two brush heads to rotate and erase in the hole 6, and when the rotating tool is moved up and down, the rust on the edge corners of the hole 6 can be removed, and the rust removal effect is better.

[0033] In some embodiments, Figure 1 and Figure 2As shown, the outer diameter of the height fixing sub-rod 11 matches the inner diameter of the height adjusting sub-rod 12, the height fixing sub-rod 11 is provided with a first threaded hole 111, the height adjusting sub-rod 12 is provided with a second threaded hole corresponding to the first threaded hole 111, and the first threaded hole 111 and the second threaded hole are connected by a locking bolt 112.

[0034] Specifically, the outer diameter of the height fixing sub-rod 11 matches the inner diameter of the height adjusting sub-rod 12, so that the height adjusting sub-rod 12 can be sleeved on the outer wall of the height fixing sub-rod 11. Before using the rust removal tool of the hole 6, the length of the height adjusting rod 1 can be adjusted first, and the length of the height adjusting rod 1 can be adjusted by pulling or pushing the length of the height adjusting rod 1. After the length of the height adjusting rod 1 is adjusted, it can be fixed. When fixing, the length of the height adjusting rod 1 is fixed by installing a locking bolt 112 in the first threaded hole 111 on the height fixing sub-rod 11 and the second threaded hole on the height adjusting sub-rod 12. Among them, the number of the first threaded holes 111 is more than the number of the second threaded holes, so that it can adapt to the fixing of the height adjusting rod 1 when different pulling lengths are reached.

[0035] In some embodiments, Figures 1 to 4 As shown, the middle portion of the width fixing sub-rod 21 is fixedly connected to the end of the height fixing sub-rod 11 .

[0036] Specifically, the middle portion of the width fixing rod 21 is fixedly connected to the end of the height fixing rod 11, so that the width fixing rod 21 is symmetrically arranged relative to the height fixing rod 11. Since the hole 6 is circular, the width fixing rod 21 is symmetrically arranged relative to the height fixing rod 11, which can better cooperate with the hole and remove rust from the hole 6.

[0037] In some embodiments, Figure 3 As shown, both ends of the width fixing sub-rod 21 are provided with external threads, the width adjusting sub-rod 22 is sleeved on the width fixing sub-rod 21 and is provided with internal threads 223 matching with the external threads.

[0038] Specifically, both ends of the width fixing sub-rod 21 are provided with external threads, the width adjusting sub-rod 22 is a barrel-shaped structure, the inner wall of the width adjusting sub-rod 22 is provided with an internal thread 223, and the width adjusting sub-rod 22 is sleeved on the outer wall of the width fixing sub-rod 21 provided with external threads, that is, the width adjusting sub-rod 22 is threadedly connected with the width fixing sub-rod 21, and the width adjusting sub-rod 22 is moved at the end of the width fixing sub-rod 21 by rotating the width adjusting sub-rod 22, thereby changing the length of the width adjusting rod 2, which can be suitable for holes 6 of different diameters.

[0039] In some embodiments, Figure 1 and Figure 2As shown, positioning nuts 3 are provided at the external threads at both ends of the width fixing sub-rod 21 , and the side walls of the positioning nuts 3 abut against the side walls of the width adjusting sub-rod 22 .

[0040] Specifically, positioning nuts 3 are provided at the external threads at both ends of the width fixing sub-rod 21, which can realize the positioning of the width adjusting sub-rod 22. After the width adjusting sub-rod 22 is rotated to a suitable position on the width fixing sub-rod 21, the width adjusting sub-rod 22 is limited by rotating the positioning nuts 3 so that the side walls of the positioning nuts 3 abut against the side walls of the width adjusting sub-rod 22, which can prevent the width adjusting sub-rod 22 from moving to the middle position of the width fixing sub-rod 21. Since the rust removing tool removes rust from the hole 6, during the rust removal process, the brush heads at both ends will rub against the side walls of the hole 6 to generate a certain thrust, which will cause the thrust to be transmitted to the middle of the width fixing sub-rod 21. Therefore, the width adjusting sub-rod 22 is limited by the positioning nuts 3 to ensure the stable operation of the rust removing tool.

[0041] In some embodiments, Figures 1 to 4 As shown, the brush head is a bowl-shaped wire brush.

[0042] Specifically, the brush head is a bowl-shaped wire brush, and the diameter of the bowl-shaped wire brush is larger than the diameter of the width adjustment rod 2, so that the bristle part of the bowl-shaped wire brush can be in close contact with the side wall or bottom wall of the hole 6, which has a better rust removal effect.

[0043] In some embodiments, Figure 2 As shown, a mounting head 222 is provided at the end of the width adjustment sub-rod 22 , a mounting hole 52 is provided on the brush head, and a fixing bolt 4 is connected after the mounting head 222 passes through the mounting hole 52 .

[0044] Specifically, the top of the width adjustment sub-rod 22 is provided with an internal thread 223, the bottom of the width adjustment sub-rod 22 is provided with a mounting head 222, the outer wall of the mounting head 222 is provided with an external thread, and the brush head is provided with a mounting hole 52. The mounting head 222 passes through the mounting hole 52 and is fixed by the fixing bolt 4. The diameter of the mounting head 222 is smaller than the width of the width adjustment sub-rod 22, so that after the mounting head 222 passes through the brush head, the side wall of the brush head can abut against the bottom of the width adjustment sub-rod 22, which plays a limiting role and makes the brush head installation more stable.

[0045] In some embodiments, Figure 2 As shown, a limiting boss 221 is further provided on the end of the width adjustment sub-rod 22 , and the mounting head 222 is arranged at the end of the limiting boss 221 . The diameter of the limiting boss 221 is greater than the diameter of the mounting head 222 .

[0046] Specifically, a limiting boss 221 is provided at the bottom of the width adjustment sub-rod 22, and the diameter of the limiting boss 221 is smaller than the diameter of the width adjustment sub-rod 22. The mounting head 222 is arranged at the end of the limiting boss 221, that is, arranged at the end of the limiting boss 221 away from the width adjustment sub-rod 22, and the diameter of the limiting boss 221 is larger than the diameter of the mounting head 222. Therefore, it can be understood that the diameters of the width adjustment sub-rod 22, the limiting boss 221 and the mounting head 222 are gradually reduced in a stepped manner. A limiting groove 51 is provided on the side wall of the brush head to cooperate with the limiting boss 221, so that after the mounting head 222 passes through the mounting hole 52 of the brush head, under the cooperation of the limiting boss 221 and the limiting groove 51, the brush head can be installed more stably, the shaking of the brush head can be reduced, and the problem of loosening of the fixing bolt 4 due to the shaking of the brush head during operation of the brush head can be avoided.

[0047] In some embodiments, Figure 4 As shown, a mounting bolt 50 is provided on the side wall of the brush head, and the mounting bolt 50 is threadedly connected to the mounting head 222 .

[0048] Specifically, in the present invention, a mounting bolt 50 may be provided on the side wall of the brush head, and the mounting bolt 50 is threadedly connected to the mounting head 222, so that the brush head can be directly screwed onto the mounting head 222. This makes installation more convenient.

[0049] The specific rust removal process of the utility model comprises:

[0050] When using the rust removal tool, first adjust the length of the height adjustment rod 1 according to the depth of the hole 6 to be rusted, pull the height adjustment sub-rod 12 to increase the length of the height adjustment sub-rod 12 and the height fixed sub-rod 11, or push and pull the height adjustment sub-rod 12 to reduce the distance between the height adjustment sub-rod 12 and the height fixed sub-rod 11, so that the height adjustment rod 1 becomes shorter, so that the length of the height adjustment rod 1 can be adjusted, and it can be applied to holes 6 of different depths. After the height adjustment of the height adjustment rod 1 is completed, the height adjustment sub-rod 12 and the height fixed sub-rod 11 are fixed by the locking bolt 112. Then, the distance between the two brush heads is adjusted according to the diameter of the hole 6, which is achieved by rotating the length of the width adjustment rod 2, specifically: by rotating the width adjustment sub-rod 22 so that the width adjustment sub-rod 22 moves at the end of the width fixed sub-rod 21, the length of the width adjustment rod 2 can be changed, which can be applied to holes 6 of different diameters. After the adjustment is completed, the rust removal tool is installed on the magnetic drill, and the hole 6 is rusted by controlling the magnetic drill to move up and down. If the bolt hole is to be derusted, the rotation direction of the magnetic drill is controlled to be in the same direction as the thread direction in the threaded hole. In this way, the brush head can be derusted along the thread to avoid damage to the thread.

[0051] You can also install the rust removal tool on the magnetic drill first, and then adjust the height adjustment rod 1 and the width adjustment rod 2. The adjustment process is the same as described above. The difference is that when adjusting the height adjustment rod 1, since the height adjustment sub-rod 12 is fixed on the magnetic drill, it is necessary to pull the height fixing sub-rod 11 to move inside the height adjustment sub-rod 12 to achieve height adjustment of the height adjustment rod 1.

[0052] Although the present invention has been described in conjunction with specific embodiments of the present invention, many replacements, modifications and variations of these embodiments will be apparent to those skilled in the art based on the foregoing description. For example, other memory architectures may use the discussed embodiments.

[0053] The embodiments of the present invention are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the embodiments of the present invention should be included in the scope of protection of the present invention.
