[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] Embodiment 1

[0041] Please refer to the attached Figures 1 to 8 , the present invention provides a technical solution:

[0042] An efficient hole-forming device for pile foundation construction includes a fixing frame 100, vertical support frames 101 are symmetrically fixed on both sides of the bottom of the fixing frame 100, and a collection frame 200 is connected to the lower middle part of the fixing frame 100 through a hoisting assembly;

[0043] A lifting ring platform 300 is provided below the fixed frame 100 at an outer position corresponding to the collecting frame 200. The top of the lifting ring platform 300 is connected to the fixed frame 100 through a lifting assembly, and a rotating assembly is provided on the outer side of the lifting ring platform 300. First vertical plates 403 are symmetrically fixed on the left and right sides of the top of the rotating assembly, and second vertical plates 406 are symmetrically fixed on the front and back sides of the top. A scraping structure is provided on the first vertical plate 403, and a leveling structure is provided on the second vertical plate 406.

[0044] The scraper structure includes a mobile frame 405 located outside the first vertical plate 403, the inner end of the mobile frame 405 is connected to the first vertical plate 403 through two hydraulic telescopic rods 404, a rotating shaft 501 is rotatably connected in the mobile frame 405, a plurality of scraper plates 500 are evenly fixed on the rotating shaft 501 along the circumferential direction, and a motor is connected to the top of the rotating shaft 501;

[0045] The leveling structure includes a moving frame 405 located outside the second vertical plate 406 , the inner end of the moving frame 405 is connected to the second vertical plate 406 via two hydraulic telescopic rods 404 , and a leveling wheel 600 is rotatably connected to the moving frame 405 .

[0046] During the drilling construction of the pile foundation hole, the support frame 101 is fixed to the outer side of the top of the pile foundation hole, the fixing frame 100 is located above the pile foundation hole, and the aggregate frame 200 is located at the position of the pile foundation hole. The aggregate frame 200 is raised and lowered in the pile foundation hole through the lifting assembly, so that the construction workers can transfer the slag generated by the drilling operation in the pile foundation hole and discharge it out of the pile foundation hole.

[0047] When the side wall of the pile foundation hole needs to be trimmed, the lifting ring 300 is moved intermittently in the pile foundation hole through the lifting assembly. After each movement of a certain distance, the position of the scraper plate 500 is adjusted through the corresponding hydraulic telescopic rod 404, so that the outer edge of the scraper plate 500 can contact the side wall of the pile foundation hole, and the rotating shaft 501 is driven by the motor to rotate multiple scraper plates 500 to perform scraping on the side wall of the pile foundation hole. At the same time, the scraper structure is moved in a circumferential direction through the rotating assembly, so that the circumferential side wall of the pile foundation hole can be fully scraped.

[0048] After the scraping structure scrapes a section of the side wall of the pile foundation hole, the position of the moving frame 405 in the leveling structure is adjusted by the corresponding hydraulic telescopic rod 404, so that the leveling wheel 600 is in contact with the wall surface of the pile foundation hole after scraping. Under the rotation of the rotating assembly, the pile foundation hole is leveled by the leveling wheels 600 on both sides, thereby improving the wall effect of the pile foundation hole and the stability of the wall soil.

[0049] Among them, the rotating component includes a rotating ring plate 400 rotatably connected to the outside of the lifting ring platform 300, the first vertical plate 403 and the second vertical plate 406 are both fixed on the top surface of the rotating ring plate 400, and a transmission ring gear 401 is fixed to the outside of the bottom of the rotating ring plate 400, and the lifting ring plate 301 is fixed to the outside of the bottom of the lifting ring platform 300. A driving gear 402 is rotatably connected to the lifting ring plate 301, and the driving gear 402 is connected to a motor, and the driving gear 402 is meshed with the inner side of the transmission ring gear 401. Through the drive of the motor and the transmission of the driving gear 402 and the transmission ring gear 401, the rotating ring plate 400 can drive the first vertical plate 403, the second vertical plate 406 and the scraper plate 500 and the leveling wheel 600 thereon to rotate, so as to trim the side wall of the pile foundation hole.

[0050] A plurality of balls are evenly arranged at the bottom of the transmission gear ring 401, and the balls contact the top surface of the lifting ring plate 301, so that the transmission gear ring 401 and the lifting ring plate 301 provide support for the outer edge of the rotating ring plate 400, and during the rotation process, the balls reduce friction and improve movement flexibility.

[0051] Among them, the lifting component includes two vertical first threaded shafts 302 symmetrically fixed on the top of the lifting ring platform 300, and two first threaded cylinders 303 are rotatably connected to the corresponding positions on the fixed frame 100. The first threaded shafts 302 are threadedly connected to the corresponding first threaded cylinders 303, and the top ends extend out of the first threaded cylinders 303. A worm gear 304 is fixed at the lower part of the first threaded cylinder 303, and a worm 305 is meshed with the rear side of the worm gear 304. The two worm gears 305 are coaxially fixed and rotatably connected to the bottom of the fixed frame 100, and one end of one of the worm gears 305 is connected to a motor.

[0052] When the height position of structures such as the scraper plate 500 and the leveling wheel 600 needs to be adjusted, the worm 305 is driven by a motor, and the two first threaded cylinders 303 are rotated simultaneously through the transmission of the worm 305 and the worm wheel 304, so that the two first threaded shafts 302 drive the lifting ring platform 300 and the structure thereon to move in the vertical direction and adjust the height position.

[0053] The hoisting assembly includes a fixing plate 104 fixed to the top of the fixing frame 100, two reels 206 are symmetrically arranged and rotatably connected on the fixing plate 104, one end of the axle of the reel 206 extends out of the fixing plate 104 and is fixed with a first gear 208, a second gear 209 is meshed with the inner side of the first gear 208, the two second gears 209 are meshed with each other, and one of the second gears 209 is connected to a motor, and the motor is fixed on the fixing plate 104;

[0054] A transverse plate 202 is fixed on the upper part of the aggregate frame 200 , and two suspension ropes 203 are symmetrically fixed on the top of the transverse plate 202 . A rope groove is provided on the fixed frame 100 at a position corresponding to the suspension rope 203 . The top end of the suspension rope 203 passes through the rope groove and is wound on the corresponding reel 206 .

[0055] When the material collecting frame 200 needs to be lifted or lowered, the two first gears 208 drive the corresponding reels 206 to rotate through the drive of the motor and the transmission of the two second gears 209, thereby simultaneously winding or unwinding the two suspension ropes 203 to achieve the lifting of the material collecting frame 200.

[0056] Embodiment 2

[0057] The structure of this embodiment is basically the same as that of the first embodiment, except that two guide wheels 105 are symmetrically arranged in the rope groove and rotatably connected, and the suspension rope 203 is located between the two guide wheels 105. The guide wheels 105 improve the guiding effect of the suspension rope 203 to avoid contact between the suspension rope 203 and the edge of the rope groove, thereby reducing the wear of the suspension rope 203. An annular groove can be arranged around the wheel surface of the guide wheel 105 to further limit the position of the suspension rope 203.

[0058] Two circular baffles 207 are symmetrically fixed on the reel 206, and the sling rope 203 is located between the two baffles 207. The baffles 207 limit the winding position of the sling rope 203 to prevent the sling rope 203 from approaching the end of the reel 206, thereby preventing the sling rope 203 from detaching from the end of the reel 206.

[0059] Embodiment 3

[0060] The structure of this embodiment is basically the same as that of the first embodiment, except that the bottom of the aggregate frame 200 is set to be open, and a bottom plate 201 is provided at the bottom end, and two vertical second threaded tubes 204 are symmetrically fixed on the top surface of the bottom plate 201, and a second threaded shaft 205 is threadedly connected in the second threaded tube 204, and the second threaded shaft 205 is rotatably connected to the cross plate 202, and the top end passes through the cross plate 202, and a turning handle is fixed. When it is inconvenient to rotate the aggregate frame 200 to dump the slag, the second threaded shaft 205 on both sides is rotated at the same time by the two turning handles, so that the two threaded tubes drive the bottom plate 201 to move downward through the action of the thread, and the bottom end of the aggregate frame 200 is opened, so that the slag can be discharged from the bottom of the aggregate frame 200, making the unloading of the aggregate frame 200 faster and more convenient.

[0061] Embodiment 4

[0062] The structure of this embodiment is basically the same as that of the first embodiment, except that a support plate 102 is fixed to the bottom end of the support frame 101, and the support plate 102 increases the contact area between the support frame 101 and the ground, thereby increasing the support stability, and a plurality of positioning bolts 103 are evenly arranged on the support plate 102, so that the support plate 102 is connected to the ground through the positioning bolts 103, further improving the support stability.
