Description

Technical Field

[0002] As we all know, 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 then the inner and outer surfaces of the steel pipes need to be rusted.

[0003] Existing rust removal devices usually only unilaterally remove rust from the inner wall or the outer wall of the steel pipe. This method has a slow rust removal efficiency, and no matter whether the inner wall or the outer wall of the steel pipe is clamped, a "dead corner area" will exist in the rust removal process, resulting in poor rust removal effect. In addition, most rust removal devices cannot meet the needs of hydraulic steel pipes of different lengths and different inner and outer diameters for rust removal.

[0031] Those skilled in the art can understand that, the output end of the second drive motor 409 drives the driving gear 404 to rotate, so that the outer teeth 403, the rotating circle 401 and the inner teeth 402 rotate as a whole, driving all the driven gears 405 to rotate synchronously, and then all the racks 408 move synchronously toward or away from the center of the rotating circle 401, so that all the clamping members 407 move synchronously toward or away from the center of the rotating circle 401, and when approaching, the hydraulic steel pipe is clamped and fixed, and when moving away, the hydraulic steel pipe is released.

[0032] Example 5

[0034] Those skilled in the art can understand that, the output end of the third electric push rod 502 is used to drive the connecting frame 503 to move forward and backward. 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, and the notch is used for loading and unloading of hydraulic steel pipes. When the connecting frame 503 moves forward, the notch opened in the middle of the right side of the fourth box body 106 is covered to prevent "waste chips" generated during subsequent rust removal from flying out of the notch and causing environmental pollution. The output end of the third drive motor 508 is used to drive the ring 509 to rotate, so that the double-headed cylinder 510 and the two sets of rust removal plates 511 rotate as a whole, so as to grind and remove rust on the inner wall of the hydraulic steel pipe. The two output ends of the double-headed cylinder 510 are extended or contracted, which can change the distance between the two sets of rust removal plates 511, thereby realizing grinding and rust removal of hydraulic steel pipes with different inner diameters, thereby improving the practicability of the device.

[0037] Those skilled in the art can understand that, the output end of the fourth drive motor 612 drives the first gear 607 to rotate, so that the two groups of second gears 608 rotate synchronously, and then the two groups of third gears 609 rotate synchronously, driving the ring gear 606 to rotate.

Conversely, when the moving piece 704 moves to the right, the third drive motor 508, the collar 509, the double-headed cylinder 510 and the rust removal plate 511 move to the right as a whole, and the connecting piece 605, the gear ring 606, the fourth electric push rod 610 and the rust removal head 611 move to the right as a whole.

[0042] Working principle and use process of this device: In order to clearly describe the working principle of the present invention, we use Figure 1 The perspective is explained as follows: S1. The output end of the third electric push rod 502 drives the connection 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 hydraulic steel pipe. The mechanical gripper 205 clamps the inner wall of the hydraulic steel pipe and makes the hydraulic steel pipe in a horizontal state. Under the action of the output end of the first stepper motor 204, the mechanical gripper 205 moves horizontally to the left, so that the hydraulic steel pipe in a horizontal state moves horizontally to the left to the inside of the first box body 103. The output end of the second electric push rod 109 drives the connection plate 111 to move to the right, so that the position of the connection plate 111 is adapted to the position of the left end of the hydraulic steel pipe extending into the first box body 103. S2. Secondly, under the action of the output end of the second driving motor 409 inside the connecting plate 111, all the clamping members 407 move synchronously toward the position close to the center of the rotating circle 401 to clamp the left end of the hydraulic steel pipe. Then, the output end of the third electric push rod 502 drives the connecting frame 503 to move forward, covering the notch opened in the middle of the right side of the fourth box body 106, preventing the "waste chips" generated during the subsequent rust removal from flying out of the notch; 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 the outer wall of the hydraulic steel pipe, and then adjust the two output ends of the double-headed cylinder 510 to extend or contract so that the distance between the two groups of rust removal plates 511 matches the inner diameter of the hydraulic steel pipe, and then simultaneously start the third stepper motor 703 inside the first sleeve 504 and the first set 601, so that the second telescopic member 709 is in an extended state, driving the fourth sleeve 507 and the fourth set 604 to move synchronously to the left, driving the rust removal plate 511 and the rust removal head 611 to move to the left, and in the process of moving to the left, synchronously start the fourth drive motor 612 and the third drive motor 508, thereby realizing the synchronous grinding and rust removal of the outer wall and the inner wall of the hydraulic steel pipe from right to left, with high efficiency; S4. Since the left end of the hydraulic steel pipe is fixed by the clamping piece 407, it is in the "dead angle area" for grinding and rust removal. At this time, the output end of the second electric push rod 109 drives the connecting plate 111 to move to the right, so that the clamped hydraulic steel pipe also moves to the right, and the first telescopic mechanism 3 drives the fourth box 106 to move left and right, so that the installation plate 112 moves left and right, so that the position of the installation plate 112 is adapted to the right end position of the hydraulic steel pipe. The clamping piece 407 in the connecting plate 111 releases the clamping of the left end of the hydraulic steel pipe, and the clamping piece 407 in the installation plate 112 clamps the right end of the hydraulic steel pipe. The rust removal head 611 continues to move to the left and the rust removal head 611 rotates with the gear ring 606, thereby achieving grinding and rust removal of the "dead angle area" and achieving comprehensive rust removal of the outer wall of the hydraulic steel pipe. S5. After the grinding and rust removal of the inner and outer walls of the hydraulic steel pipe is completed, the first box 103 is driven to rotate by the output end of the first driving motor 102, so that the left end of the clamped hydraulic steel pipe is tilted downward, so that all the "waste scraps" generated during the grinding and rust removal of the hydraulic steel pipe fall into the first box 103, the second box 104, the third box 105 and the fourth box 106. After that, the mechanical gripper 205 takes the hydraulic steel pipe out of the first box 103 and puts it back on the external conveyor. Repeat the above steps to continue to remove rust from other hydraulic steel pipes. The whole process is automated, meeting the needs of the staff; S6. After all the water conservancy steel pipes are completely derusted, the mounting plate 108 is driven 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 opening opened in the middle of the left side of the first box body 103, and the external collection bag is tied to the opening, and the first box body 103 is continued to be driven to rotate through the output end of the first drive motor 102, so that all the "waste debris" falls into the collection bag, maintaining a clean environment and further meeting the needs of the staff.
