[0035] See also Figure 1-6 , the present invention provides a technical solution:

[0036] A surface descaling device for special equipment comprises a workbench 1, wherein the top outer wall of the workbench 1 is provided with arc-shaped grooves in the left and right directions;

[0037] A cleaning cylinder 2, which is rotatably disposed on the upper side of the workbench 1;

[0038] A processing shaft 3, which is arranged at the inner edge of the cleaning cylinder 2, at least one processing shaft 3 is arranged, and a vibration descaling assembly is connected to the left end of the processing shaft 3;

[0039] A vertical rod 4, which is fixedly arranged at the left end of the arc-shaped groove;

[0040] A centering cover 5, which is arranged on the right side of the vertical rod 4 and is rotatably matched with the cleaning cylinder 2;

[0041] The continuously rotating fixing mechanism 6 comprises a rotating cover 7 and a rotating drive. The rotating drive drives the rotating cover 7 to rotate, thereby indirectly driving the special equipment to rotate.

[0042] In this technical solution, the special equipment is rotated in the cleaning cylinder 2 by setting a continuous rotating fixing mechanism 6, and the side of the special equipment is processed through the processing shaft 3, which saves manpower and material resources, improves the efficiency of polishing, and at the same time improves the overall aesthetics after painting and improves the polishing effect.

[0043] Specifically, the centering cover 5 is arranged in a hemispherical shell structure, and a plurality of evenly distributed descaling brushes A8 are fixedly arranged on the inner wall of the centering cover 5 , and a plurality of evenly distributed descaling brushes B9 are fixedly arranged on the circumferential outer wall of the processing shaft 3 in the cleaning cylinder 2 .

[0044] In this technical solution, the device can be centered by means of the centering cover 5, and at the same time, the provision of the descaling brush A8 and the descaling brush B9 can achieve overall descaling of the device.

[0045] Furthermore, a storage groove 10 is provided on the right side of the top outer wall of the workbench 1, and at least one through groove 13 is provided in the storage groove 10. The through grooves 13 are rotatably connected to a telescopic rod 12 through a hinge seat, and the other end of the telescopic rod 12 is rotatably connected to the same fixed baffle 11.

[0046] In this technical solution, by setting the telescopic rod 12 and the fixed baffle 11, the fixed baffle 11 can be stored in the storage groove 10 to make way for the exit for the placement of special equipment. After installation, the equipment can be fixed and centered directly by telescoping, which is very convenient.

[0047] Furthermore, a rotation groove A14 is formed on the left outer wall of the fixed baffle 11, and the rotation drive includes rotating a driving centering disk 15 disposed inside the rotation groove A14.

[0048] The outer wall of the driving centering plate 15 is provided with an annular rotating guide rail 16 , and the inner wall of the rotating groove A14 is provided with a rotating guide groove 17 matched with the rotating guide rail 16 , and the rotating guide rail 16 is slidably connected with the rotating guide groove 17 .

[0049] A first motor 18 is fixedly disposed on the right side wall of the fixed baffle 11 . The output shaft of the first motor 18 passes through the outer wall of the fixed baffle 11 to the left and extends to the inside of the rotating groove A14 and is connected and fixed to the axis of the driving centering disk 15 .

[0050] In this technical solution, the centering disc 15 is driven to rotate the device by friction on one end of the device, so that the device can rotate on its own to perform descaling.

[0051] Furthermore, the vibration descaling assembly includes a horizontal connecting rod and at least one pulling rod 19, the left end of the horizontal connecting rod is sleeved on the top of the vertical rod 4, and the right end of the horizontal connecting rod is connected to the left end of the centering cover 5; the outer wall of the horizontal connecting rod is provided with at least one rotating groove B23, and the outer end of the pulling rod 19 is fixedly connected with a rotating ball 22, and the rotating ball 22 is slidably limited in the rotating groove B23, so that a rotating connection is formed between the pulling rod 19 and the horizontal connecting rod.

[0052] A rotating seat 20 is fixedly provided at the inner end of the pulling rod 19, a compensation groove 21 is opened at the right end of the processing shaft 3, a rotating shaft is provided between the inner walls of the rotating seat 20, and the rotating shaft is slidably set in the compensation groove 21, so that a rotating connection is formed between the rotating seat 20 and the processing shaft 3, and the right end of the processing shaft 3 slides through the outer wall of the centering cover 5 and extends into the cleaning cylinder 2.

[0053] In this technical solution, the reciprocating motion of the processing shaft 3 will cause the angle of the rotating seat 20 to change. At this time, the compensation groove 21 can compensate for the distance generated by the arc, avoiding the processing shaft 3 from getting stuck, and the vibration processing can be carried out smoothly.

[0054] The right end of the processing shaft 3 is rotatably connected to a roller 24 via a pin shaft, and the roller 24 is rollingly arranged on the right end side wall of the cleaning cylinder 2 .

[0055] It is worth noting that the right end side wall of the cleaning cylinder 2 is arranged in an annular wave shape.

[0056] In this technical solution, the processing shaft 3 can vibrate along the wave trajectory following the waves. The vibrating descaling assembly also includes a driving drive, which can indirectly drive the processing shaft 3 to vibrate back and forth by driving the cleaning cylinder 2 to rotate.

[0057] In this technical solution, through the setting of the vibration descaling component, during cleaning, the processing shaft 3 will perform reciprocating vibration motion left and right to cooperate with the cleaning action of the special equipment's rotation, thereby diversifying the cleaning trajectory and further improving the cleaning efficiency.

[0058] In this technical solution, the reciprocating motion of the processing shaft 3 will cause the angle of the rotating seat 20 to change. At this time, the compensation groove 21 can compensate for the distance generated by the arc, avoiding the processing shaft 3 from getting stuck, and the vibration processing can be carried out smoothly.

[0059] In addition, a spring 25 is sleeved on the left end of the processing shaft 3 , the right end of the spring 25 is pressed against the outer wall of the centering cover 5 , and the left end is pressed against the rotating seat 20 .

[0060] In this technical solution, the spring 25 squeezes the processing shaft 3 so that the roller 24 on the processing shaft 3 can always fit the outer wall of the cleaning cylinder 2, so that vibration cleaning can be carried out stably, avoiding the situation where effective cleaning cannot be performed when it is too tight.

[0061] In addition, the driving mechanism includes a rotating rack 26 fixedly arranged on the side wall of the cleaning cylinder 2, and a limit groove 27 is provided on the top of the workbench 1 to slide with the rotating rack 26; a transmission cavity connected to the limit groove 27 is provided at the lowest point thereof, and a transmission gear 28 meshingly connected with the rotating rack 26 is provided in the transmission cavity; a motor installation cavity is provided on one side of the transmission cavity, and a second motor 29 is provided in the motor installation cavity, and the transmission gear 28 is coaxially fixedly connected with the output shaft of the second motor 29. In this technical solution, the wavy wall on the side of the outer wall can be rotated and changed in position by the rotation of the cleaning cylinder 2, thereby driving multiple processing shafts 3 or the same processing shaft 3 to move in multiple different distances, thereby improving the processing effect.

[0062] When the surface descaling treatment device for special equipment is needed, first, the special equipment is placed inside the cleaning cylinder 2, and the controller drives the telescopic rod 12 to push the fixed baffle 11 upward, and drives the centering plate 15 to squeeze one end of the special equipment, and cooperates with the centering cover 5 to achieve centering clamping of the special equipment;

[0063] At this time, the first motor 18 drives the centering disc 15 to rotate, and the rotating guide rail 16 arranged on the outer wall of the centering disc 15 slides inside the rotating guide groove 17, and can only rotate at this time. Due to the friction of the centering disc 15 on the special equipment, the special equipment is driven to rotate. At this time, the descaling brush A8 and the descaling brush B9 will act on the outer wall of the special equipment to descale;

[0064] At this time, by controlling the driving of the second motor 29 to rotate, the transmission gear 28 is driven to rotate. At this time, the rotating rack 26 meshing with the transmission gear 28 rotates, thereby driving the cleaning cylinder 2 to rotate. At this time, the right end side wall of the cleaning cylinder 2 is wavy, and the roller 24 on the processing shaft 3 will move in accordance with the wavy wall due to the action of the spring 25. During the movement, the rotating seat 20 is further assisted in limiting the position, so that the processing shaft 3 reciprocates and vibrates to process the outer wall of the special equipment.
