Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] As Figures 1 to 6 shown, the present utility model provides a rust removal device for steel pipe processing, including a support leg 1. The top end of the support leg 1 is fixedly installed with an operating table 2. The middle part of the outer surface of the operating table 2 is fixedly sleeved with a bracket 3. The top of the left end of the bracket 3 is provided with a limiting groove 4. The inside of the limiting groove 4 is movably sleeved with a limiting block 5. The inside of the top end of the bracket 3 is movably sleeved with a laser generator 6. The left end of the laser generator 6 is fixedly connected to the right end of the limiting block 5. The top of the outer surface of the laser generator 6 is fixedly sleeved with a rectangular plate 7. The bottom end of the rectangular plate 7 is movably connected to the top end of the bracket 3. The right end of the rectangular plate 7 is fixedly installed with a round rod 8. The top of the right end of the bracket 3 is fixedly sleeved with a driving motor 9. The other end of the output shaft of the driving motor 9 is fixedly sleeved with a driving shaft 10. The right side of the outer surface of the driving shaft 10 is fixedly sleeved with a rotating rod 11. The bottom of the inner surface of the rotating rod 11 and the right side of the outer surface of the round rod 8 are movably sleeved.
[0024] When the drive motor 9 starts, it will cause the drive shaft 10 to drive the rotating rod 11 to rotate. Since the inner surface of the rotating rod 11 is movably sleeved on the outer surface of the round rod 8, under the action of the rotating rod 11, the round rod 8 will be pushed, thus driving the rectangular plate 7 and the laser generator 6 to move along the inner surface of the bracket 3. The mutual cooperation of the limiting groove 4 and the limiting block 5 can restrict the movement of the laser generator 6 to ensure the stability of the movement of the laser generator 6, so as to realize the adjustment of the rust removal position of the rust removal device, thereby increasing the rust removal range and facilitating the rust removal operation of steel pipes with different diameters.
[0025] Among them, support plates 12 are respectively and fixedly installed on the left and right sides of the top end of the operating platform 2, and a support plate 13 is fixedly installed on the top end of the support plate 12.
[0026] The existence of the support plates 12 and the support plate 13 will play a role in supporting the steel pipe, thus facilitating the operator to move the steel pipe.
[0027] Among them, a collecting pipe 14 is fixedly sleeved inside the middle end of the operating platform 2, and a sealing end cover 15 is fixedly installed at the bottom end of the collecting pipe 14.
[0028] Due to the existence of the collecting pipe 14, it will be convenient to collect the flue gas during rust removal to prevent it from escaping everywhere.
[0029] Among them, a fan 16 is fixedly installed at the bottom end of the sealing end cover 15, an air inlet pipe 17 is fixedly installed at the top end of the fan 16, the top end of the air inlet pipe 17 penetrates through the sealing end cover 15 and extends to the inside of the sealing end cover 15, and an air outlet pipe 18 is fixedly installed at the bottom end of the fan 16.
[0030] When the fan 16 starts, it will cause air to enter from the air inlet pipe 17 and then discharge from the air outlet pipe 18, so that the inside of the collecting pipe 14 and the sealing end cover 15 is in a negative pressure state, and then the flue gas is absorbed under the action of the atmospheric pressure.
[0031] Among them, a filter plate 19 is movably sleeved at the bottom of the left end of the collecting pipe 14, the right end of the filter plate 19 penetrates through the collecting pipe 14 and extends to the right side of the collecting pipe 14, a handle 20 is fixedly installed at the left end of the filter plate 19, and the right end of the handle 20 is movably connected to the left end of the collecting pipe 14.
[0032] When the handle 20 is pulled, the filter plate 19 will be separated from the collecting pipe 14, thus facilitating the extraction of the filter plate 19 for cleaning.
[0033] Among them, a baffle 21 is movably connected to the middle part of the inner wall at the rear side of the handle 20, limiting rods 22 are respectively and fixedly installed on the left and right sides of the top end of the baffle 21, and a cross plate 23 is fixedly sleeved on the top of the outer surface of the limiting rod 22.
[0034] Due to the existence of the baffle 21 , the handle 20 will be blocked, thereby locking the position of the handle 20 .
[0035] Among them, the bottom end of the cross plate 23 is movably connected with a fixed block 24, the rear end of the fixed block 24 is fixedly connected to the front end of the collecting pipe 14, the inner surfaces of the left and right ends of the fixed block 24 are movably sleeved with the outer surface of the limiting rod 22, and the left and right sides of the bottom end of the fixed block 24 are respectively fixedly installed with springs 25 located outside the limiting rod 22, and the other end of the spring 25 is fixedly connected to the top of the baffle 21.
[0036] Due to the restoring effect of the spring 25, the baffle 21 will return to its original position after moving.
[0037] The working principle and use process of this utility model:
[0038] First, the operator places the steel pipe on the top of the support plate 13, and then starts the laser generator 6 to start the rust removal operation. If the diameter of the steel pipe exceeds the rust removal range of the laser generator 6, the operator starts the drive motor 9, so that the drive shaft 10 drives the rotating rod 11 to rotate. At this time, the inner wall of the rotating rod 11 will generate a thrust on the outer surface of the round rod 8, pushing the round rod 8 through the rectangular plate 7 and moving with the laser generator 6, so that the rust removal position can be adjusted, thereby facilitating the rust removal operation on steel pipes of different diameters, thereby improving the rust removal range and applicability of the rust removal device.
[0039] During the rust removal process, the operator starts the fan 16, so that the air inside the collection pipe 14 and the sealing end cover 15 is discharged through the outlet pipe 18 and is in a negative pressure state. At this time, under the action of the external atmospheric pressure, the smoke generated during the rust removal process will enter the collection pipe 14, and be discharged from the outlet pipe 18 after being filtered by the filter plate 19. When the filter plate 19 is blocked, the operator pushes the baffle 21, so that the baffle 21 moves upward along the inner surface of the fixed block 24 with the limit rod 22 and compresses the spring 25, thereby separating the baffle 21 and the handle 20, and removing the obstruction of the baffle 21 to the handle 20. Then the operator can pull out the filter plate 19 through the handle 20 to clean the filter plate 19. The cooperation of various mechanisms realizes the absorption of the smoke generated during the rust removal process and prevents it from dissipating everywhere.
