[0027] See also Figures 1 to 4 The external grinding mechanism 3 includes an installation box 301, and the installation box 301 is fixedly installed on the upper end of the installation platform 1 close to the placement platform 201. A grinding telescopic rod 302 is fixedly installed on the inner wall of the installation box 301. A spring telescopic rod 303 is rotatably installed on the upper end of the grinding telescopic rod 302.

The winding motor 306 is started, and the winding drum 307 drives the grinding belt 308 to start moving, so as to polish the outer wall of the refrigeration pipe.

[0028] See also Figures 1 to 8The inner grinding mechanism 4 includes a mounting frame 401, which is fixedly mounted on the side end of the mounting platform 1, and a connecting telescopic frame 402 is fixedly mounted on the side end of the mounting frame 401, and a mounting rod 403 is fixedly mounted on the end of the connecting telescopic frame 402 away from the mounting frame 401, and a contraction motor 404 is fixedly mounted on the side end of the mounting frame 401 close to the mounting rod 403, and a contraction disk 405 is fixedly mounted on the output end of the contraction motor 404, and a connecting rope 406 is wound on the outer wall of the contraction disk 405, and the connecting rope 406 is wound on the outer wall of the contraction disk 405. One end of the connecting rope 406 away from the shrink disk 405 is fixedly installed at the side end of the mounting rod 403. When the refrigeration pipe moves and pushes the mounting rod 403 to move, the connecting telescopic frame 402 begins to extend to a certain length. When the refrigeration pipe needs to be moved to a suitable position, the shrinking motor 404 is started to make the shrinking rope start to wind up the connecting rope 406, so that the connecting rope 406 pulls the mounting rod 403 to move, so that the connecting telescopic frame 402 shrinks to a suitable length. The upper end of the mounting rod 403 is fixedly installed with a water-passing rod 40 7. A water inlet telescopic pipe 408 is fixedly installed at the lower end of the water-through rod 407, and a water pump 409 is fixedly installed at one end of the water inlet telescopic pipe 408 away from the water-through rod 407.

Under normal circumstances, the water outlet telescopic pipe 411 is in a folded state. When water is filled into the water outlet telescopic tube 411, the hydraulic pressure in the water outlet telescopic tube 411 begins to increase, and the hydraulic pressure causes the water outlet telescopic tube 411 to begin to expand and unfold, so that when water is filled into the water outlet telescopic tube 411, the water outlet telescopic tube 411 begins to extend, and there is a certain driving force, and the magnitude of the driving force is proportional to the magnitude of the hydraulic pressure in the water outlet telescopic tube 411. After the water outlet telescopic tube 411 is fully extended and extended, when it begins to absorb water, the hydraulic pressure of the water outlet telescopic tube 411 is negative pressure, causing the water outlet telescopic tube 411 to shrink and fold.

[0029] See also Figures 1 to 8, a water outlet telescopic pipe 411 is fixedly installed with a water outlet pipe 412 at one end away from the water passing rod 407, and a movable frame 413 is fixedly installed at one end of the water outlet telescopic pipe 412 away from the water outlet telescopic pipe 411, and a limiting ring 414 is fixedly installed on the outer wall of the water outlet telescopic pipe 412 close to the water outlet telescopic pipe 411. The limiting ring 414 installed on the outer wall of the water outlet pipe 412 allows the water outlet pipe 412 to remain in the center position of the refrigeration pipe after the inner wall grinding mechanism is placed inside the refrigeration pipe, and a rotating joint 415 is fixedly installed at one end of the water outlet telescopic pipe 412 away from the water outlet telescopic pipe 411. The above-mentioned rotating joint 415 is a prior art and will not be described in detail here. A water outlet ring 416 is rotatably installed at one end of the rotating joint 415 away from the water outlet pipe 412, and the rotating joint 415 installed between the water outlet pipe 412 and the water outlet ring 416 allows the water outlet ring 416 to maintain a water outlet state during the rotation process. A plurality of hydraulic telescopic rods 417 are installed in a row, and a grinding plate 418 is fixedly installed at one end of the hydraulic telescopic rod 417 away from the water outlet circle 416, and a grinding rod 419 is fixedly installed at one end of the grinding plate 418, and the above-mentioned grinding plate 418 and grinding rod 419 are both arranged in an arc shape. When liquid enters the hydraulic telescopic rod 417, the hydraulic telescopic rod 417 pushes the grinding plate 418 and the grinding rod 419 to squeeze and contact the inner wall of the refrigeration pipe, and in this process, the friction force generated by the grinding plate 418 and the grinding rod 419 is the same as the driving force generated by the water outlet telescopic pipe 411, so that the grinding plate 418 and the grinding rod 419 will not move, and a sliding groove 420 that matches the grinding rod 419 is opened at the side end of the grinding plate 418 away from the grinding rod 419, and the grinding rod 419 is slidably installed in the sliding groove 420, and the above-mentioned grinding plate 418 and grinding rod 419 are both arranged to be elastic materials.

[0030] See also Figures 1 to 7 A drainage pipe 421 is fixedly installed at the side end of the water outlet pipe 412, and a control valve 422 is fixedly installed at one end of the drainage pipe 421 away from the water outlet circle 416. The control valve 422 is electrically controlled, so that the staff can control the strength of the grinding plate 418 and the grinding rod 419 grinding the inner wall by changing the drainage amount of the control valve 422. A drainage circle 423 is fixedly installed at one end of the control valve 422 away from the drainage pipe 421, and the drainage circle 423 is fixedly installed on the inner wall of the mobile frame 413. When the drainage circle 423 starts to spray water, the drainage circle 42 The water sprayed will provide a certain driving force to the drain ring 423, and the water pressure in the water outlet ring 416 of the drain ring 423 begins to decrease to a certain size during the process, so that when the control valve 422 is adjusted to a certain size, the water outlet telescopic pipe 411 begins to extend, and the grinding plate 418 and the grinding rod 419 grind the inner wall of the refrigeration pipe. When the drain valve is opened to a certain size, water flows out of the drain ring 423, the length of the water outlet telescopic pipe 411 remains unchanged, the refrigeration pipe moves, and the grinding plate 418 and the grinding rod 419 rotate to grind the inner wall of the refrigeration pipe.

[0031] See also Figures 1 to 8 A turbine rod 424 is rotatably installed on the inner wall of the water outlet pipe 412, and a driving gear 425 is fixedly installed at one end of the turbine rod 424. The side end of the driving gear 425 is meshedly connected with a transmission gear 426, and the transmission gear 426 is rotatably installed on the side end of the mobile frame 413. The side end of the transmission gear 426 away from the driving gear 425 is meshedly connected with a driven ring gear 427, and the driven ring gear 427 is fixedly installed on the side end of the water outlet circle 416. When water passes through the water outlet pipe 412, the water flows through the turbine rod 424, and the turbine rod 424 drives the driving gear 425 to start rotating. The driving gear 425 drives the driven ring gear 427 to rotate through the transmission gear 426, so that the water outlet circle 416 starts to rotate, making it more convenient for the grinding plate 418 and the grinding rod 419 to grind the inner wall of the refrigeration pipe.

[0032] The working principle of the present invention is: when the refrigeration pipe needs to be polished, the refrigeration pipe is placed in the placement ring 202, and the fixing ring 203 is rotated to insert the fixing bolt into the fixing groove 205 set in the placement ring 202, so that the placement ring 202 and the rolling wheel 209 in the fixing ring 203 squeeze and fix the refrigeration pipe, making the placement and fixation of the refrigeration pipe more convenient; After the refrigeration pipe is fixed, when the inner and outer walls of the refrigeration pipe need to be polished, the mobile frame 413 is placed on the inner wall of the refrigeration pipe, the polishing telescopic rod 302 is started, the polishing belt 308 is wrapped around the outer wall of the refrigeration pipe, the driving motor 210 is started, the active turntable 211 starts to rotate the driven turntable 213 through the transmission belt 212, the fixed cylinder 208 drives the rolling wheel 209 to start rotating, and the rolling wheel 209 starts to move the refrigeration pipe and rotates at the same time, so that when the refrigeration pipe moves to polish the inner and outer walls of the refrigeration pipe, the refrigeration pipe does not need to stop, and the refrigeration pipe can be polished continuously; When the grinding belt 308 is wrapped around the outer wall of the refrigeration pipe and the refrigeration pipe starts to move, the winding motor 306 is started to grind the outer wall of the refrigeration pipe, and the moving direction of the grinding belt 308 is opposite to the rotation direction of the refrigeration pipe, so that the outer wall of the refrigeration pipe can be polished more evenly and efficiently; When the movable frame 413 is placed on the inner wall of the refrigeration pipe, the water pump 409 is started to fill the water in the water outlet telescopic pipe 411, and the control valve 422 is opened to make the refrigeration pipe move. The grinding plate 418 and the grinding rod 419 installed on the movable frame 413 grind the inner wall of the refrigeration pipe, and the drainage ring 423 starts to drain water to flush the position of the grinded inner wall of the refrigeration pipe. When the water flows through the water outlet pipe 412, the water flow drives the turbine pipe to start rotating, so that the driving gear The wheel 425 drives the water outlet circle 416 to start rotating, and the grinding plate 418 and the grinding rod 419 start to rotate in the opposite direction to the refrigeration pipe on the inner wall of the refrigeration pipe. When the water outlet telescopic tube 411 completely enters the refrigeration pipe, the drainage volume of the drainage pipe 421 is increased in the water outlet telescopic tube 411, so that the water outlet telescopic tube 411 pushes the grinding plate 418 and the grinding rod 419 to move in the inner wall of the refrigeration pipe to grind the inner wall of the refrigeration pipe, thereby making it more convenient to grind the inner wall of the refrigeration pipe with a longer length.
