[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] like Figure 1-20As shown, the present invention has the following five specific embodiments.

[0053] Example 1

[0054] An outer surface cleaning and grinding device for a pre-buried water conservancy pipeline comprises a pipeline body 100 and further comprises:

[0055] A base 1, with a mounting chamber 11 and a pedestal 12 fixedly connected to the left and right sides of the base 1, respectively; a turntable 13 is rotatably connected to the right side of the inner cavity of the mounting chamber 11; a main motor 14 is fixedly connected to the left center of the mounting chamber 11; an output shaft of the main motor 14 is rotatably connected to the left side plate of the mounting chamber 11, and a head of the output shaft of the main motor 14 is fixedly connected to the center of the turntable 13;

[0056] The mounting frame 2 is located on the right side of the turntable 13 and is symmetrically arranged up and down. The mounting frame 2 is provided with track grooves 21 on the front and rear sides. A seat plate 22 is slidably connected in the mounting frame 2. The front and rear sides of the seat plate 22 are fixedly connected with track blocks 23. A knife shaft 24 is rotatably connected in the seat plate 22. A knife head 25 is fixedly connected to the bottom of the knife shaft 24.

[0057] An adjustment mechanism, the mounting frame 2 is connected to the turntable 13 through the adjustment mechanism, and the adjustment mechanism is used to adjust the angle of the mounting frame 2 and the distance relative to the center of the turntable 13;

[0058] A driving mechanism, which is used to drive the cutter head 25 to rotate on one hand, and to drive the seat plate 22 to move in the mounting frame 2 on the other hand;

[0059] The supporting mechanism and the fixing mechanism are located on the pedestal 12 , and the supporting mechanism and the fixing mechanism respectively support and fix the pipeline body 100 .

[0060] In this embodiment, Figure 1 As shown, the angle of the mounting frame 2 and the distance relative to the center of the turntable 13 are adjusted by the adjusting mechanism, so that the inclination angle of the cutter head 25 and the distance relative to the center of the turntable 13 are adjusted.

[0061] The pipe body 100 is supported by a supporting mechanism and fixed by a fixing mechanism, and the left end of the pipe body 100 is close to the cutter head 25 .

[0062] When the equipment is working, the main motor 14 drives the turntable 13 to rotate, and the mounting frame 2 is connected to the turntable 13 through the adjustment mechanism. When the turntable 13 rotates, the mounting frame 2 and the cutter head 25 are driven to rotate.

[0063] In this process, the driving mechanism drives the cutter head 25 to rotate on the one hand, and drives the seat plate 22 to move rightward in the mounting frame 2 on the other hand. Since the mounting frame 2 is inclined, the height of the seat plate 22 increases continuously during the movement to the right, and the rotating cutter head 25 grinds the pipe body 100, thereby processing the inclined surface, that is, Figure 1 The shaded area shown in G is ground.

[0064] Example 2

[0065] The adjustment mechanism includes a first screw rod 31 and a second screw rod 32; a first transmission cavity 33 is provided at the center of the rotating disk 13, and slide grooves 34 are provided on both sides of the first transmission cavity 33. The first screw rod 31 is rotatably connected in the slide groove 34, and the head of the first screw rod 31 extends into the first transmission cavity 33 and is fixedly connected to a first driven bevel gear 35. The right side of the first transmission cavity 33 is rotatably connected to a first rotating shaft 36, and a first driving bevel gear 37 is fixedly connected to the left end of the first rotating shaft 36. The two first driven bevel gears 35 are meshed with the first driving bevel gear 37. A first adjustment seat 38 is slidably connected in the slide groove 34, and the first adjustment seat 38 is meshed with the first screw rod 31. A connecting seat 39 is fixedly connected to the right side of the first adjustment seat 38, and the left end of the mounting frame 2 is hinged to the connecting seat 39. The second screw rod 32 is rotatably connected to the side of the connecting seat 39 that is away from each other. Limit rods 310 are fixedly connected to both sides of the second screw rod 32. A second adjustment seat 311 is meshed on the second screw rod 32. The second adjustment seat 311 is slidably connected to the limit rod 310, and a pull plate 312 is hinged between the second adjustment seat 311 and the mounting frame 2.

[0066] In this embodiment, Figure 2 and Figure 4 As shown, the knob at the head of the first rotating shaft 36 drives it to rotate, so that the first active bevel gear 37 rotates, and the first driven bevel gear 35 meshing therewith rotates, so that the first screw rod 31 rotates. Since the first driven bevel gear 35 meshes with the first active bevel gear 37 on both sides, the two first screw rods 31 rotate in opposite directions, and the thread grooves on the two first screw rods 31 are set to have the same rotation direction, that is, the two first adjustment seats 38 are close to or away from each other, so as to adjust the position of the mounting frame 2, and indirectly adjust the distance between the cutter head 25 and the center of the turntable 13.

[0067] When the second screw rod 32 rotates, it can drive the second adjustment seat 311 to move. The second adjustment seat 311 drives the mounting frame 2 to rotate through the pulling plate 312, so as to adjust the inclination degree of the mounting frame 2 and the cutter head 25.

[0068] Example 3

[0069] The driving mechanism includes a driving shaft 41, a moving box 42, a feed screw 43 and a feed assembly; an L-shaped frame 45 is symmetrically fixed to the right side of the turntable 13, the driving shaft 41 is rotatably connected between the turntable 13 and the vertical plate of the L-shaped frame 45, a rotating gear 46 is fixed to the left end of the driving shaft 41, a gear ring 47 meshing with the rotating gear 46 is fixed to the inner wall of the left side plate of the installation bin 11, a moving groove 48 is opened on the horizontal plate of the L-shaped frame 45, and a moving groove 48 is fixed to the moving groove 48. The movable rod 49 is fixedly connected to the movable box 42 with a movable seat 410 which is slidably connected to the movable rod 49. A sleeve 411 is rotatably connected between the left and right side plates of the movable box 42. The drive shaft 41 is slidably connected in the sleeve 411. A transmission bar 412 is evenly fixedly connected to the circumference of the drive shaft 41. A transmission groove 413 corresponding to the transmission bar 412 is opened on the inner wall of the sleeve 411. A transmission shaft 414 is rotatably connected to the side of the movable box 42 close to the mounting frame 2. The transmission shaft 414 is rotatably connected to the drive shaft 414. 14 is linked with the sleeve 411 through a bevel gear pair 415, a square groove 416 is provided at the end of the transmission shaft 414 and the knife shaft 24, a cover tube 417 is fixedly connected to the end of the transmission shaft 414 and the knife shaft 24, a protective sleeve 418 is fixedly connected between the cover tubes 417, a positioning shaft 419 is rotatably connected to the cover tube 417, a soft shaft 420 is fixedly connected between the positioning shafts 419, and a square block 421 is fixedly connected to the end of the positioning shaft 419 away from the soft shaft 420, and the square block 421 is fixedly connected to the square block 421. The track block 23 is inserted into the square groove 416, a slide bar 422 is fixedly connected to the outer wall of the track block 23, and the front and rear sides of the moving box 42 are rotatably connected to the slide seat 424 through the second rotating shaft 423. The slide bar 422 is slidably connected in the slide seat 424, and the feed screw 43 is rotatably connected to the side of the L-shaped frame 45 away from the moving box 42. The moving box 42 is fixedly connected to an ear seat 425, and the ear seat 425 is meshed with the feed screw 43. The feed assembly is used to drive the feed screw 43 to rotate.

[0070] Preferably, a fixing plate 426 is fixedly connected to the right side of the slide seat 424 , a positioning screw 427 is meshed in the fixing plate 426 , and positioning holes 428 are evenly opened on the front and rear sides of the moving box 42 around the second rotating shaft 423 .

[0071] In this embodiment, when the inclination angle of the mounting frame 2 is adjusted, the inclination angle of the seat plate 22 changes synchronously, such as Figure 3-Figure 4 ,as well as Figure 6 As shown, since the slide bar 422 is fixed to the track block 23, the slide bar 422 changes its angle along with the seat plate 22, and the slide bar 422 drives the slide seat 424 to rotate around the second rotating shaft 423, and the angle of the slide seat 424 changes synchronously with the mounting frame 2, that is, the slide seat 424 is always parallel to the mounting frame 2.

[0072] like Figure 18-19 As shown, point F1 in the figure is the rotation connection point between the mounting frame 2 and the connecting seat 39, F2 is the center point of the seat plate 22, and F3 is the center point of the second rotating shaft 423. Fig.18The mounting frame 2 is in a horizontal state. When the mounting frame 2 and the seat plate 22 rotate, the seat plate 22 drives the slide 424 to rotate through the slide rod 422, so that the slide 424 and the seat plate 22 are always in a parallel state with each other, but the distance between the slide 424 and the seat plate 22 will continue to decrease, and the sliding of the slide rod 422 in the slide 424 can adapt to the change of the distance between the slide 424 and the seat plate 22, and the seat plate 22 will slide to the right in the mounting frame 2 to keep the slide rod 422 and the seat plate 22 perpendicular to each other, that is, when the angle of the seat plate 22 and the cutter head 25 is adjusted, the position of the cutter head 25 will also be appropriately raised, and then the height of the cutter head 25 can be adjusted.

[0073] like Figure 6 As shown, when the angle is adjusted, the angle between two adjacent positioning holes 428 is fixed, and the angle of the mounting frame 2 can be determined by the number of positioning holes 428 through which the positioning screw 427 passes. After the adjustment is completed, the positioning screw 427 can be screwed into the positioning hole 428. Assuming that the angle between two adjacent positioning holes 428 is 5°, when the mounting frame 2 starts to be adjusted from a horizontal position, the positioning screw 427 can be screwed in when it reaches the position of the fourth positioning hole 428.

[0074] like Figure 8 As shown in the figure, point H1 is the position of the connecting seat 39, point H2 is the position of the cutter head 25, straight line R1 is the position of the mounting frame 2, and straight line R2 is the position of the slide bar 422. When the height of the cutter head 25 is adjusted, the connecting seat 39 rises to h1. At this time, the mounting frame 2 reaches the r1 position, and the cutter head 25 reaches the h2 position. It can be seen that since the position of the slide bar 422 is fixed, the height-adjustable cutter head 25 will slide a little to the left on the mounting frame 2 when moving upward, which will cause its height to drop, but the overall height of the cutter head 25 will rise.

[0075] That is, when the adjustment mechanism is working, the inclination angle of the seat plate 22 and the cutter head 25 is adjusted first. Although the height of the cutter head 25 will change a little at this time, it can be densely distributed when the height of the mounting frame 2 is adjusted. When the height of the mounting frame 2 is adjusted, the change in the height of the cutter head 25 will be slightly smaller than the change in the height of the mounting frame 2, but it will be adjusted in the expected direction.

[0076] like Figure 1 , Figure 3-Figure 7 as well as Figure 9-10As shown, the main motor 14 drives the turntable 13 to rotate, thereby driving the mounting frame 2 to rotate, and the cutter head 25 rotates around the center of the turntable 13. At this time, due to the existence of the gear ring 47, the rotating gear 46 rotates to drive the drive shaft 41 to rotate. The drive shaft 41 drives the sleeve 411 to rotate through the transmission bar 412 and the transmission groove 413. The sleeve 411 drives the transmission shaft 414 to rotate through the bevel gear pair 415. The transmission shaft 414 drives the cutter shaft 24 and the cutter head 25 to rotate through the soft shaft 420. The cutter head 25 rotates in a tilted state.

[0077] The feed assembly drives the feed screw 43 to rotate, thereby driving the moving box 42 to move to the right. The moving box 42 drives the seat plate 22 to move through the slide rod 422, thereby moving the cutter head 25.

[0079] The feed assembly includes an arc-shaped rack 441, a power column 442, a movable disk 443 and a feed gear 444; an arc-shaped rack 441 is fixedly connected to the upper and lower inner walls of the mounting bin 11, and the two arc-shaped racks 441 are staggered laterally. An arc-shaped first permanent magnet 446 is fixedly connected to the position of the arc-shaped rack 441 on the inner wall of the left side plate of the mounting bin 11, and the curvature of the first permanent magnet 446 is greater than that of the arc-shaped rack 441. The power column 442 is rotatably connected to the turntable 13 and is symmetrically arranged up and down. The right end of the power column 442 is fixedly connected to the feed screw 43, and the first Cavity 447, a second cavity 448 and a third cavity 449, a movable disk 443 is slidably connected in the second cavity 448, a spring 4410 is fixed between the movable disk 443 and the right side of the third cavity 449, a connecting rod 4411 is fixed to the left side of the movable disk 443, the connecting rod 4411 is slidably connected in the first cavity 447, and transmission grooves 4412 are evenly arranged on the circumference of the connecting rod 4411, a transmission tooth 4413 is fixed to the inner wall of the first cavity 447, a feed gear 444 is fixed to the left end of the connecting rod 4411, and a second permanent magnet 4414 is fixed to the left side of the feed gear 444.

[0080] Preferably, the polarities of the left sides of the two second permanent magnets 4414 are the same, the polarity of the right side of the upper first permanent magnet 446 is the same as the polarity of the left side of the second permanent magnet 4414, and the polarity of the right side of the lower first permanent magnet 446 is opposite to the polarity of the left side of the second permanent magnet 4414;

[0081] When the upper moving plate 443 contacts the left side of the second cavity 448, the upper spring 4410 is in a natural state, and the upper feed gear 444 is located between the two arc-shaped racks 441; when the upper moving plate 443 contacts the right side of the second cavity 448, the upper feed gear 444 and the arc-shaped rack 441 on the right side overlap in horizontal position;

[0082] When the lower movable disk 443 contacts the right side of the second cavity 448, the lower spring 4410 is in a natural state, and the lower feed gear 444 is located between the two arc-shaped racks 441; when the lower movable disk 443 contacts the left side of the second cavity 448, the lower feed gear 444 overlaps with the arc-shaped rack 441 on the left side in lateral position.

[0083] Preferably, a manual handle 429 is fixedly connected to the right end of the feed screw 43 .

[0084] In this embodiment, when the rotating disk 13 moves to Figure 1 When the status shown is:

[0085] like Fig.11 As shown, the first permanent magnet 446 above has a magnetic repulsion force on the second permanent magnet 4414, the movable disk 443 above overcomes the retraction force of the spring 4410 and contacts the right side of the second cavity 448, and the feed gear 444 above is engaged with the arc-shaped rack 441 on the left. When the turntable 13 rotates, the arc-shaped rack 441 drives the feed gear 444 to rotate.

[0086] like Fig.12 As shown, the first permanent magnet 446 at the bottom has a magnetic attraction to the second permanent magnet 4414, the movable disk 443 at the bottom overcomes the retraction force of the spring 4410 and contacts the left side of the second cavity 448, and the feed gear 444 at the bottom is engaged with the arc-shaped rack 441 on the right side. When the turntable 13 rotates, the arc-shaped rack 441 drives the feed gear 444 to rotate.

[0087] like Fig.13 As shown, when the second permanent magnet 4414 is misaligned with the first permanent magnet 446, under the action of the spring 4410, Figure 1 The moving plates 443 at the upper and lower positions are in contact with the left and right sides of the second cavity 448 respectively, and the two feed gears 444 are both located between the arc-shaped racks 441 .

[0088] Figure 1 When the power column 442 at the upper middle position moves downward, the magnetic attraction of the first permanent magnet 446 also causes the moving disk 443 to contact the left side of the second cavity 448; Figure 1 When the power column 442 at the lower middle position moves upward, the magnetic repulsion force of the first permanent magnet 446 also causes the moving disk 443 to contact the right side of the second cavity 448 .

[0089] In summary, Figure 1 The feed gear 444 at the upper middle position will rotate only when it moves to the upper position, and the feed gear 444 at the lower position will rotate only when it moves to the lower position, that is, the feed gear 444 rotates once when it moves one circle.

[0090] Because the curvature of the first permanent magnet 446 is greater than that of the arc-shaped rack 441 , the feed gear 444 is in place in advance before meshing with the arc-shaped gear, thereby allowing the meshing operation to proceed smoothly.

[0091] When the feed gear 444 rotates, it drives the connecting rod 4411 to rotate. The connecting rod 4411 makes the power column 442 rotate through the cooperation of the transmission groove 4412 and the transmission tooth 4413, thereby driving the feed screw 43 to rotate, and further driving the cutter head 25 to move.

[0092] The pitch of the feed screw 43 , the number of teeth of the feed gear 444 and the arc gear are set so that the length of each movement of the cutter head 25 along the mounting frame 2 is smaller than the diameter of the cutter head 25 .

[0093] Since two cutter heads 25 are provided, and the two cutter heads 25 grind on both sides of the pipe body 100 at the same time, and the cutter heads 25 only feed once when they rotate one circle, Fig. 20 As shown in the figure, M1 and M2 are respectively the grinding area and feed area of ​​one of the cutter heads 25, m1 and m2 are respectively the grinding area and feed area of ​​the other cutter head 25. When the cutter head 25 is feeding, the grinding area of ​​the cutter head 25 is an arc, and the grinding effect is not good at this time, but it can be compensated by the grinding of the other cutter head 25, so that the grinding effect is better.

[0094] After the cutting is completed, when the feed gear 444 is out of mesh with the arc-shaped rack 441, the feed screw 43 can be driven to rotate in the opposite direction by the manual handle 429, so that the moving box 42 and the cutter head 25 can be manually reset.
