Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of the present application.

[0023] Embodiment one In order to reduce the noise and dust pollution when cutting the pile head, please refer to Figures 1-3 The embodiment provides a fan foundation pile head automatic breaking machine, which comprises a base 1 and a fixed track 2, a supporting plate 3 is slidably connected to the fixed track 2, a cutting assembly 4 and a dustproof and noise reduction assembly 5 are installed on the supporting plate 3, a driver 6 for driving the supporting plate 3 to move along the fixed track 2 is installed on one side of the supporting plate 3, the dustproof and noise reduction assembly 5 comprises an extension rod 51, an annular frame 52, a water pipe 53, an air duct 54 and a sewage recovery assembly 55, the extension rod 51 is fixed on the supporting plate 3, the annular frame 52 is fixed on the movable end of the extension rod 51, the annular frame 52 is hollow, a plurality of air extraction holes are formed in one side of the annular frame 52, the air duct 54 is in communication with the annular frame 52, the water outlet of the water pipe 53 faces the cutting assembly 4, and the sewage recovery assembly 55 is installed below the annular frame 52, the cutting assembly 4 comprises a motor 41 and a cutting wheel 42, the top of the motor 41 is fixed to a support 9, and the cutting wheel 42 is fixed to the output end of the motor 41.

[0024] In use, the base 1 is placed on the ground, the base 1 is gradually moved close to the pile head, until the cutting assembly 4 is in contact with the pile head, then the extension rod 51 is moved, until the annular frame 52 is also in contact with the pile head, at this time, the water pipe 53 is connected with an external water pipe, water is continuously supplied to the cutting assembly 4, the air duct 54 is connected with an external gas pipeline, air in the annular frame 52 is continuously extracted, air and dust around the pile head are extracted through the air extraction holes, then the cutting assembly 4 is started, the cutting assembly 4 cuts the pile head, after cutting, slotting, stripping of the steel bar, driving of the steel pile, pile head breaking and lifting away are performed, and a complete pile head breaking process is completed. In the process of cutting the pile head by the cutting assembly 4, the dustproof and noise reduction assembly 5 reduces the dust and noise pollution during cutting. The specific steps are as follows: Firstly, the water pipe 53 continuously waters the cutting position of the pile head by the cutting assembly 4, and the continuously flowing water at the cutting position not only has a cooling and lubricating effect, but also reduces the direct friction coefficient between the cutting blade and the concrete particles, makes the cutting process smoother, reduces the friction, naturally greatly reduces the sharp noise generated by the friction, and can also change the dust generated by the cutting into mud, so that the dust cannot vibrate and spread sound in the air, thereby eliminating this part of the noise, and the annular frame 52 wraps the cutting area, and the dust generated by the cutting is sucked away when it spreads to the surrounding, the dust is sucked away by the air pipe 54 through the air suction hole and the annular frame 52, so as to prevent the dust generated by the cutting from spreading to the surrounding, reduce the noise and dust pollution generated when the pile head is cut, and prevent the dust from spreading to the surrounding, reduce the possibility of affecting the vision and breathing of the cutting staff.

[0025] In order to enable the cutting wheel 42 to move around the pile head for cutting, referring to Figure 1 The support plate 3 is fixedly connected with a support 9 at the top, the support 9 is fixedly connected with a limiting frame 10 at the top, the water pipe 53 and the air pipe 54 penetrate through the limiting frame 10, the base 1 is provided with a receiving groove 11 at the top, the base 1 is slidably connected with a cover plate 12 covering the receiving groove 11 at the top, and a plurality of arc-shaped tracks 13 are arranged in the receiving groove 11.

[0026] In use, the cover plate 12 is opened, the arc-shaped tracks 13 are taken out from the receiving groove 11, and then the arc-shaped tracks 13 are continuously spliced on both sides of the fixed track 2 until the fixed track 2 and the arc-shaped tracks 13 are spliced into a complete annular track, and then the adjacent arc-shaped tracks 13 and the fixed track 2 are fixed by using gaskets and bolts. Since the fixing mode belongs to a commonly used structure, it is not marked in the figure. The driver 6 drives the support plate 3 and the cutting assembly 4 to move along the annular track, the cutting wheel 42 rotates to cut the pile head, and after the pile head is cut, the arc-shaped tracks 13 are taken off from the fixed track 2 and are re-placed in the receiving groove 11, so as to facilitate the assembly of the track around the pile head, enable the cutting wheel 42 to move around the pile head for cutting, reduce the difficulty of cutting the pile head at a fixed height by the cutting wheel 42, facilitate the track to be received in the base 1 after cutting, and reduce the space occupied by the whole device when not in use.

[0027] Since the support plate 3, the cutting assembly 4 and the dustproof and noise reduction assembly 5 need to extend to the outside of the base 1 to contact the pile head, the gravity center of the whole device is offset to the outside of the base 1, which is easy to make the whole device fall down. In order to correct the gravity center of the whole device, after the arc-shaped track 13 is assembled to the fixed track 2, the counterweight is put into the storage groove 11, and after the air inside the annular frame 52 is sucked out, the air pressure difference between the inside and the outside of the annular frame 52 absorbs the annular frame 52 on the pile head, so that the annular frame 52 is supported by the pile head from the side, which is convenient to increase the counterweight to adjust the gravity center distribution of the whole device, and the pile head is used to support the device from the side during the cutting process, so as to reduce the possibility of falling down of the device due to the offset of the gravity center.

[0028] Embodiment two In order to prevent the spray water from gathering at the bottom of the pile head and causing excessive water accumulation around the pile head to affect cutting, refer to Figures 1-4 On the basis of embodiment one, the sewage recovery assembly 55 includes an outer frame 551, a sliding frame 552, a connecting block 553 and a water absorption assembly 554. The connecting block 553 is fixed at the bottom of the annular frame 52, the sliding frame 552 is fixed at the bottom of the connecting block 553, the outer frame 551 is sleeved outside the sliding frame 552, the water absorption assembly 554 is fixed at the bottom of the support plate 3, and the movable end of the water absorption assembly 554 extends to the inside of the sliding frame 552. The top of the sliding frame 552 is provided with a notch with the same curvature as the annular frame 52, and the inner side of the top of the annular frame 52 is a slope.

[0029] When the annular frame 52 is moved to tightly contact the side of the pile head, the annular frame 52 drives the sliding frame 552 to slide along the outer frame 551 through the connecting block 553, so that the sliding frame 552 also tightly contacts the side of the pile head. After the water in the water pipe 53 is poured to the cutting wheel 42, the water flows downward along the surface of the pile head. First, a part of the water is blocked by the annular frame 52 and guided to flow away from the pile head along the slope at the bottom of the inner side of the annular frame 52 until it flows onto the sliding frame 552, so that this part of the water flows away from the pile head. The remaining water continues to flow downward along the outside of the pile head from the gap between the annular frame 52 and the pile head. This part of the water is blocked by the sliding frame 552 which tightly contacts the pile head and flows to the outer frame 551 along the sliding frame 552. The water absorption assembly 554 absorbs the water on the side of the sliding frame 552 close to the pile head, so that the amount and height of the water on the side of the sliding frame 552 close to the pile head are obviously higher than those on the other side of the sliding frame 552. The water flowing downward along the pile head is guided to flow faster to the outer frame 551 along the sliding frame 552 due to the height difference. A container is placed below the outer frame 551 to collect water, which can guide the spray water during the cutting of the pile head to flow away from the pile head, so as to reduce the possibility of water gathering around the pile head and causing excessive water accumulation around the pile head to affect cutting.

[0030] Embodiment three In order to achieve the purpose of accelerating the water on the surface of the pile head to flow to the sliding frame 552 and reducing the mud and debris mixed in the water from adhering to the surface of the water absorption assembly 554, refer to Figures 1-5On the basis of the first embodiment, the water absorption assembly 554 includes a telescopic electric cylinder 5541, an arc-shaped frame 5542, and a sponge column 5543. The telescopic electric cylinder 5541 is fixed at the bottom of the support plate 3. The arc-shaped frame 5542 is fixed with the movable end of the telescopic electric cylinder 5541. The rotating shaft of the sponge column 5543 is rotatably connected with the arc-shaped frame 5542. The arc-shaped frame 5542 is provided with a motor on one side for driving the sponge column 5543 to rotate. The sponge column 5543 is fixedly connected with a plurality of rubber strips 7 on the outside. The rubber strips 7 are fixedly connected with a plurality of plastic cones 8 on one side. The plastic cones 8 are slidably connected with the sponge column 5543.

[0031] In use, the sliding frame 552 is tightly attached to the outside of the pile head. The sprayed water flows down along the pile head to the sliding frame 552, and then is blocked by the sliding frame 552 and flows along the sliding frame 552. At this time, the telescopic electric cylinder 5541 is started to drive the arc-shaped frame 5542 and the sponge column 5543 to reciprocate. When the sponge column 5543 moves close to the sliding frame 552, the sponge column 5543 contacts the sliding frame 552. The maximum extension distance of the telescopic electric cylinder 5541 is controlled to avoid the sponge column 5543 from pressing the sliding frame 552. The water on the sliding frame 552 is sucked into the sponge column 5543, so that a greater height difference between the water on the outside of the pile head and the water on the sliding frame 552 is generated. The water on the outside of the pile head can flow to the sliding frame 552 more quickly, and the amount of water flowing down along the pile head from the gap between the pile head and the sliding frame 552 is reduced.

[0032] When the sponge column 5543 is pushed to move towards the sliding frame 552, the sponge column 5543 presses the connecting block 553. On the one hand, the sponge column 5543 is rotated by utilizing the friction between the rubber strips 7 and the connecting block 553, so that the other side of the sponge column 5543 with less water absorption is directed towards the sliding frame 552. On the other hand, the connecting block 553 deforms the sponge column 5543 to squeeze out the water in the sponge column 5543 and then flow to the sliding frame 552 from both sides of the connecting block 553. When the rubber strips 7 are squeezed, the plastic cones 8 are moved relative to the surface of the sponge column 5543, thereby shoveling away the mud and debris attached to the surface of the sponge column 5543. Finally, the telescopic electric cylinder 5541 drives the sponge column 5543 to move away from the sliding frame 552, and the above process is repeated. The sponge column 5543 continuously absorbs the water on the sliding frame 552 and then discharges the water from both sides of the connecting block 553, so that the water near the pile head on the sliding frame 552 can be absorbed, the height difference between the water on the outside of the pile head and the water on the sliding frame 552 is increased, and more water flowing down along the pile head flows along the sliding frame 552 to the designated position. Meanwhile, the mud and debris attached to the surface of the sponge column 5543 can be cleaned during the water absorption process.
