Description

Technical Field

[0001] The present invention relates to the technical field of rust removal, and particularly to an environmentally friendly rust removal device for processing steel pipes used in water conservancy projects. Background Art

[0002] As is well known, steel pipes are often used in water conservancy projects. After long-term use, the inner and outer surfaces of the steel pipes will be corroded, and thus rust removal treatment needs to be carried out on the inner and outer surfaces of the steel pipes.

[0003] Existing rust removal devices usually only carry out rust removal on either the inner wall or the outer wall of the steel pipe unilaterally. In this way, the rust removal efficiency is relatively slow, and whether the inner wall or the outer wall of the steel pipe is clamped, there will be a "dead corner area" during the rust removal process, resulting in a poor rust removal effect. In addition, most rust removal devices cannot meet the rust removal requirements for water conservancy steel pipes with different lengths and different inner and outer diameters, and the practicability is relatively low, making it difficult to meet the needs of workers. Summary of the Invention

This technical solution solves the problems in the above background art that existing rust removal devices usually only carry out rust removal on either the inner wall or the outer wall of the steel pipe unilaterally.

A loading and unloading mechanism 2 is arranged in the middle of the top of the base plate 1. Two groups of fixed plates 101 are welded on the left side of the top of the base plate 1. A first box body 103 is rotatably connected between the two groups of fixed plates 101. A first driving motor 102 for driving the first box body 103 to rotate is arranged outside the front fixed plate 101. A second box body 104, a third box body 105 and a fourth box body 106 are slidably connected inside the first box body 103. A first telescopic mechanism 3 is installed on the first box body 103 and the fourth box body 106. A first electric push rod 107 is arranged at the bottom of the first box body 103. The output end of the first electric push rod 107 is fixedly connected with a mounting plate 108. A second electric push rod 109 is installed inside the mounting plate 108.

A first rust removal mechanism 5 and a second rust removal mechanism 6 are installed on the right side of the fourth box body 106.

[0043] Embodiment 2

[0044] Please refer to Figure 2 As shown in the figure, the loading and unloading mechanism 2 includes a first lead screw 202 and a first guide rod 203. First fixing blocks 201 are fixedly installed on the left and right sides of the top of the base plate 1. The first lead screw 202 is rotatably connected between the two groups of first fixing blocks 201. The first guide rod 203 is fixedly connected between the two groups of first fixing blocks 201. A mechanical gripper 205 is threadedly connected to the outer surface of the first lead screw 202. The mechanical gripper 205 is slidably connected to the first guide rod 203. The outer end of the first lead screw 202 is fixedly connected to the output end of a first stepping motor 204. The first stepping motor 204 is arranged outside the right first fixing block 201.

[0045] Those skilled in the art can understand that the output end of the first stepping motor 204 drives the first lead screw 202 to rotate, causing the mechanical gripper 205 to move left and right along the outer surface of the first guide rod 203. The mechanical gripper 205 can grasp the external water conservancy steel pipe and transfer it to the interiors of the first box body 103, the second box body 104, the third box body 105, and the fourth box body 106 for rust removal. After the rust removal is completed, it can also transfer the water conservancy steel pipe to the external conveyor.

[0046] Embodiment 3

[0047] Please refer to Figure 3 and Figure 4 As shown, the first telescopic mechanism 3 includes a first telescopic member 312. A first connecting shaft 306 is fixedly connected to the left side of the top of the first box body 103. A first connecting arm 307 and a second connecting arm 308 are rotatably connected to the first connecting shaft 306. A second connecting shaft 309 is installed on the right side of the top of the fourth box body 106. A third connecting arm 310 and a fourth connecting arm 311 are rotatably connected to the second connecting shaft 309. The right ends of both sides of the first telescopic member 312 are respectively rotatably connected to the third connecting arm 310 and the fourth connecting arm 311, and the left ends of both sides of the first telescopic member 312 are respectively rotatably connected to the first connecting arm 307 and the second connecting arm 308.

[0048] Please refer to Figure 3 and Figure 4 As shown, the first telescopic mechanism 3 further includes a second fixing block 301. There are two groups of second fixing blocks 301, both of which are installed on the top of the first box body 103. A second lead screw 302 is rotatably connected between the two groups of second fixing blocks 301. A moving block 305 is threadedly connected to the second lead screw 302. The moving block 305 is slidably connected to the second guide rod 303. The two ends of the second guide rod 303 are respectively fixedly connected to the inner walls of the two groups of second fixing blocks 301. A second stepping motor 304 is installed on one of the second fixing blocks 301. The outer end of the second lead screw 302 is fixedly connected to the output end of the second stepping motor 304. The moving block 305 is connected to the first telescopic member 312. T-shaped grooves 313 are provided on the inner walls of the tops of the first box body 103, the second box body 104, and the third box body 105. T-shaped plates 314 are connected to the tops of the second box body 104, the third box body 105, and the fourth box body 106. The T-shaped plates 314 are slidably connected to the T-shaped grooves 313.

[0049] Those skilled in the art can understand that the output end of the second stepping motor 304 drives the second lead screw 302 to rotate, causing the moving block 305 to move horizontally left and right. When the moving block 305 moves to the right, the first telescopic member 312 is in a stretched state, driving the second box body 104, the third box body 105, and the fourth box body 106 to be pulled out from the first box body 103. When the moving block 305 moves to the left, the first telescopic member 312 is in a retracted state, driving the second box body 104, the third box body 105, and the fourth box body 106 to retract into the interior of the first box body 103. And by the cooperation of the T-shaped plate 314 and the T-shaped groove 313, the movement stability of the second box body 104, the third box body 105, and the fourth box body 106 is improved.

[0050] Example 4

[0051] Please refer to Figure 8 As shown, the clamping mechanism 4 includes a rotating ring 401. The rotating ring 401 is rotatably connected to the interiors of both the connecting disk 111 and the mounting disk 112. Inner teeth 402 and outer teeth 403 are respectively connected to the inner and outer circumferential surfaces of the rotating ring 401. A set of driving gears 404 and several sets of driven gears 405 are also rotatably connected to the connecting disk 111 and the mounting disk 112.

[0052] Please refer to Figure 7 As shown, the driving gear 404 meshes with the outer teeth 403, and several sets of driven gears 405 all mesh with the inner teeth 402. And fixed rings 406 are welded inside both the connecting disk 111 and the mounting disk 112. Several sets of clamping members 407 are slidably connected to the interiors of the fixed rings 406. Rack bars 408 are fixedly installed on the clamping members 407. Several sets of rack bars 408 respectively mesh with several sets of driven gears 405. A second driving motor 409 for driving the driving gear 404 to rotate is also provided inside the connecting disk 111 and the mounting disk 112.

[0053] Those skilled in the art can understand that the output end of the second driving motor 409 drives the driving gear 404 to rotate, causing the outer teeth 403, the rotating ring 401, and the inner teeth 402 to rotate as a whole, driving all the driven gears 405 to rotate synchronously. Furthermore, all the rack bars 408 move synchronously towards or away from the position of the center of the rotating ring 401. Thus, all the clamping members 407 move synchronously towards or away from the position of the center of the rotating ring 401. When approaching, the water conservancy steel pipe is clamped and fixed, and when moving away, the clamping of the water conservancy steel pipe is released.

[0054] Example 5

[0055] Please refer to Figure 6 、 Figure 9 and Figure 10As shown in the figure, the first rust removal mechanism 5 includes a mounting member 501, which is fixedly connected to the back of the fourth box body 106 by bolts. A third electric push rod 502 is fixedly installed on the back of the mounting member 501. The output end of the third electric push rod 502 is connected to a connecting frame 503. A first sleeve 504 is installed on the outside of the connecting frame 503. A second sleeve 505, a third sleeve 506, and a fourth sleeve 507 are slidably connected inside the first sleeve 504. A third drive motor 508 is fixedly installed at the outer end of the fourth sleeve 507. The output end of the third drive motor 508 is connected to a collar 509, and a double-headed cylinder 510 is arranged inside the collar 509. Both output ends of the double-headed cylinder 510 are fixedly connected to rust removal plates 511.

[0056] Those skilled in the art can understand that the output end of the third electric push rod 502 drives the connecting frame 503 to move back and forth. When the connecting frame 503 moves backward, the notch opened in the middle of the right side of the fourth box body 106 is exposed. This notch is used for the loading and unloading of water conservancy steel pipes. When the connecting frame 503 moves forward, it covers the notch opened in the middle of the right side of the fourth box body 106 to prevent the "waste chips" generated during subsequent rust removal from flying out of the notch, thus avoiding environmental pollution. The output end of the third drive motor 508 drives the collar 509 to rotate, so that the double-headed cylinder 510 and the two rust removal plates 511 rotate as a whole to realize the grinding and rust removal of the inner wall of the water conservancy steel pipe. The two output ends of the double-headed cylinder 510 extend or contract, which can change the distance between the two rust removal plates 511, thereby realizing the grinding and rust removal of water conservancy steel pipes with different inner diameters and improving the practicability of the device.

[0057] Embodiment 6

[0058] Please refer to Figure 4 、 Figure 11 and Figure 12 As shown in the figure, the second rust removal mechanism 6 includes a first kit 601, which is fixedly installed on the right side of the fourth box body 106. A second kit 602, a third kit 603, and a fourth kit 604 are slidably connected inside the first kit 601. The outer end of the fourth kit 604 is fixedly connected to a connecting member 605. A set of gear rings 606, a set of first gears 607, two sets of second gears 608, and two sets of third gears 609 are rotatably connected to the left side of the connecting member 605. Both sets of second gears 608 are meshed with the first gear 607. Both sets of third gears 609 are meshed with the gear ring 606. The two sets of third gears 609 are respectively meshed with the two sets of second gears 608. A fourth drive motor 612 is installed on the right side of the connecting member 605. The first gear 607 is fixedly connected to the output end of the fourth drive motor 612. A fourth electric push rod 610 is installed on the gear ring 606. The output end of the fourth electric push rod 610 is connected to a fixed seat. A rust removal head 611 is rotatably connected inside the fixed seat.

[0059] Those skilled in the art can understand that the output end of the fourth driving motor 612 drives the first gear 607 to rotate, so that the two second gears 608 rotate synchronously, and then the two third gears 609 rotate synchronously, driving the ring gear 606 to rotate. In the present invention, two second gears 608 and two third gears 609 are provided here. On the one hand, because the connecting piece 605 is provided with a notch, the continuous rotation of the ring gear 606 is realized. On the other hand, the speed regulation purpose can be achieved through the gears; the rotation of the ring gear 606 makes the fourth electric push rod 610 and the rust removal head 611 rotate integrally, realizing the grinding and rust removal of the outer wall of the water conservancy steel pipe. By the elongation or contraction of the output end of the fourth electric push rod 610, the rust removal head 611 is close to or far from the center position of the ring gear 606, so as to realize the grinding and rust removal of water conservancy steel pipes with different outer diameters, further improving the practicability of the device.

And a limiting sliding rod 711 slidably connected to the limiting sliding groove 710 is installed on the second telescopic member 709.

[0063] Those skilled in the art can understand that the output end of the third stepping motor 703 drives the third lead screw 702 to rotate, causing the moving part 704 to move horizontally left and right. When the moving part 704 moves to the left, the second telescopic part 709 is in a stretched state, and then the second sleeve 505, the third sleeve 506, and the fourth sleeve 507 move synchronously to the left, and the second set 602, the third set 603, and the fourth set 604 move synchronously to the left, realizing the overall leftward movement of the third driving motor 508, the collar 509, the double-headed cylinder 510, and the rust removal plate 511, as well as the overall leftward movement of the connecting piece 605, the gear ring 606, the fourth electric push rod 610, and the rust removal head 611. Conversely, when the moving part 704 moves to the right, the overall rightward movement of the third driving motor 508, the collar 509, the double-headed cylinder 510, and the rust removal plate 511, as well as the overall rightward movement of the connecting piece 605, the gear ring 606, the fourth electric push rod 610, and the rust removal head 611 are realized.

[0064] The working principle and usage process of this device: To clearly describe the working principle of the present invention, we will elaborate from the perspective of Figure 1 as follows:

[0065] S1. The output end of the third electric push rod 502 drives the connecting frame 503 to move backward, exposing the notch opened in the middle of the right side of the fourth box body 106. The mechanical gripper 205 grabs the right end of the external water conservancy steel pipe. The mechanical gripper 205 clamps the inner wall of the water conservancy steel pipe and keeps the water conservancy steel pipe in a horizontal state. Under the action of the output end of the first stepping motor 204, the mechanical gripper 205 moves horizontally to the left, causing the horizontally placed water conservancy steel pipe to move horizontally to the left into the interior of the first box body 103. The output end of the second electric push rod 109 drives the connecting disk 111 to move to the right, making the position of the connecting disk 111 adapt to the position of the left end of the water conservancy steel pipe extending into the interior of the first box body 103;

[0066] S2. Secondly, under the action of the output end of the second driving motor 409 inside the connecting disk 111, all the clamping parts 407 move synchronously towards the position close to the center of the rotation circle 401 to clamp the left end of the water conservancy steel pipe. Then, the output end of the third electric push rod 502 drives the connecting frame 503 to move forward to cover the notch opened in the middle of the right side of the fourth box body 106, preventing the "waste chips" generated during subsequent rust removal from flying out of the notch;

[0067] S3. Adjust the extension or contraction of the output end of the fourth electric push rod 610 so that the rust removal head 611 fits against the outer wall of the water conservancy steel pipe. Then, adjust the extension or contraction of the two output ends of the double-headed cylinder 510 so that the distance between the two groups of rust removal plates 511 is adapted to the inner diameter of the water conservancy steel pipe. Then, simultaneously start the third stepping motor 703 inside the first sleeve 504 and the first kit 601, so that the second telescopic member 709 is in a stretched state, driving the fourth sleeve 507 and the fourth kit 604 to move synchronously to the left, driving both the rust removal plate 511 and the rust removal head 611 to move to the left. And during the movement to the left, synchronously start the fourth drive motor 612 and the third drive motor 508, thus realizing the synchronous grinding and rust removal of the outer wall and the inner wall of the water conservancy steel pipe from right to left, with high efficiency;

[0068] S4. Since the left end of the water conservancy steel pipe is fixed by being clamped by the clamping member 407, this place is in the "dead corner area" of grinding and rust removal. At this time, drive the connecting disk 111 to move to the right through the output end of the second electric push rod 109, so that the clamped water conservancy steel pipe also moves to the right. Drive the fourth box body 106 to move left and right through the first telescopic mechanism 3, so that the mounting disk 112 moves left and right, so that the position of the mounting disk 112 is adapted to the position of the right end of the water conservancy steel pipe. The clamping member 407 in the connecting disk 111 releases the clamping of the left end of the water conservancy steel pipe, while the clamping member 407 in the mounting disk 112 clamps the right end of the water conservancy steel pipe. The rust removal head 611 continues to move to the left and the rust removal head 611 rotates along with the gear ring 606, thus realizing the grinding and rust removal of the "dead corner area" and achieving the comprehensive rust removal of the outer wall of the water conservancy steel pipe;

[0069] S5. After the grinding and rust removal of the inner and outer walls of the water conservancy steel pipe are completed, drive the first box body 103 to rotate through the output end of the first drive motor 102, so that the left end of the clamped water conservancy steel pipe is in an inclined downward state, so that all the "waste chips" generated during the grinding and rust removal of the water conservancy steel pipe fall into the interiors of the first box body 103, the second box body 104, the third box body 105 and the fourth box body 106. Then, the mechanical gripper 205 takes out the water conservancy steel pipe from the first box body 103 and puts it back on the external conveyor. Repeating the above steps can continue to rust remove other water conservancy steel pipes, and the whole process is automated, meeting the needs of the staff;

[0070] S6. After all the water conservancy steel pipes are completely rust removed, drive the mounting plate 108 to move to the left through the output end of the first electric push rod 107, so that the cover plate 110 moves to the left, exposing the through hole opened in the middle of the left side of the first box body 103. Tie the external collection bag to this through hole. Continue to drive the first box body 103 to rotate through the output end of the first drive motor 102, so that all the "waste chips" fall into the collection bag, maintaining the environmental cleanliness and further meeting the needs of the staff.
