Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a pile drilling processing device for building foundation construction and an operating method thereof. Background Art

[0002] Bored piles are a type of infrastructure widely used in construction projects. They are a type of pile foundation supported by processes such as drilling and pouring concrete. With the development of the construction industry, bored piles have become an indispensable part of construction projects.

[0003] In the prior art, when drilling piles, a rotary drilling machine is usually used to drive a rotary drilling drill to perform rotary drilling. It is impossible to know whether there are large stones in the foundation soil layer before construction. When the rotary drilling drill moves to the large stone and the edge of the large stone invades the edge of the pile drilling hole, the rotary drilling drill will crush the large stone, and the large stone will drive the soil near its surface, causing defects in the hole wall of the pile drilling hole. When large stones appear in a concentrated manner, the soil layer around the hole wall of the pile drilling hole will loosen and the soil layer will collapse, which can easily lead to construction accidents. When concrete is poured later, more concrete needs to be poured to ensure the stability of the soil layer, which increases the construction cost. When rainwater enters the hole wall, it will cause damage to the hole wall and the hole wall is prone to collapse. Summary of the invention

The rain shield mechanism includes a frame 207. The outer cylinder 203 is used in conjunction with the frame 207. A rain shield 208 is symmetrically slidably connected inside the frame 207. The rain shield 208 can prevent rainwater from entering the pile hole and causing damage to the hole wall of the pile hole.

[0021] like Figure 1-Figure 6 As shown, the filling mechanism also includes a telescopic rod 301, and the telescopic rod 301 is symmetrically arranged in the outer cylinder 203. The top of the telescopic rod 301 is connected to a plane where the rotary drilling device does not rotate by bolts. The telescopic end of the telescopic rod 301 is fixedly connected with a guide ring 302, and the guide ring 302 is rotatably connected to the boss frame 201. A plurality of evenly distributed guide grooves are provided at the bottom of the guide ring 302, and a slide groove is provided on the top of the six tamping blocks 202. An elastic telescopic shaft 303 is vertically slidably connected in the slide groove, and the telescopic end of the elastic telescopic shaft 303 movably passes through the boss frame 201 and slides into the guide groove of the guide ring 302. A screw auger 304 is fixedly connected to the middle part of the drill rod 1, and the screw auger 304 is used to transport soil to the upper side of the guide ring 302.

[0022] like Figure 3-Figure 7As shown, the loosening mechanism also includes a gear ring 401, the top of the guide ring 302 is fixedly connected to the gear ring 401, the top of the gear ring 401 is sleeved and rotatably connected to a protection box 402, one end of the support shaft 204 rotates through the protection box 402 and is fixedly connected to a gear meshing with the gear ring 401, and the protection box 402 is used to prevent soil from contacting the meshing surfaces of the gear ring 401 and the gear.

[0023] like Figure 8 As shown, the loosening mechanism also includes a guide sleeve 501, the outer wall of the protection box 402 is symmetrically fixed with the guide sleeve 501, the inner wall of the guide sleeve 501 is movably connected with the sleeve 502, the inner wall of the guide sleeve 501 is provided with a special-shaped groove, the outer wall of the sleeve 502 is fixed with a protrusion used in conjunction with the special-shaped groove, the sleeve 502 is movably sleeved on the outer wall of the support shaft 204, the outer wall of the sleeve 502 is hinged with one end of a connecting rod 503, the other end of the connecting rod 503 is hinged to the loosening plate 206, the protrusion slides along the special-shaped groove of the guide sleeve 501, and the connecting rod 503 can drive the loosening plate 206 to swing back and forth.

[0024] like Figure 2 As shown, it also includes a soil accumulation plate 601 . Six evenly distributed soil accumulation plates 601 are fixed to the inner wall of the outer cylinder 203 . The six soil accumulation plates 601 can push the soil to the side close to the six compacting blocks 202 .

[0025] When it is necessary to drill a foundation pile, the drill rod 1 is rotated to be perpendicular to the foundation through a rotary drilling machine in the existing equipment (the rotary drilling machine is a prior art and will not be described here), and the bottom of the frame 207 is placed on the foundation surface, and the rotary drilling machine is started first to drive the drill rod 1 to rotate, thereby causing the two rain shields 208 to move away from each other, and then the drill rod 1 drops downward to start rotary drilling, and the drill rod 1 drives the boss frame 201 to rotate through the cross bar, and the boss frame 201 drives the six tamping blocks 202 therein to rotate, and drives the outer cylinder 203 to rotate, and the outer cylinder 203 drives the swivel 205, the protection box 402 and the gear to revolve around the center of the outer cylinder 203 through the support shaft 204, thereby causing the two loosening plates 206 to revolve around the center of the outer cylinder 203, and the telescopic ends of the two telescopic rods 301 The guide ring 302 drives the gear ring 401 to remain stable so that the gear ring 401 cannot rotate, and then the gear is caused to rotate by the gear ring 401, and the gear drives the swivel 205 to rotate through the support shaft 204, and the swivel 205 drives the loosening plate 206 to rotate, and the loosening plate 206 drives the sleeve 502 to rotate through the connecting rod 503, and the sleeve 502 drives the protrusion to slide along the special-shaped groove of the guide sleeve 501, and the protrusion drives the sleeve 502 to reciprocate horizontally on the outer wall of the support shaft 204, and the sleeve 502 drives the loosening plate 206 to swing back and forth with the connection point of the swivel 205 as the center of the circle through the connecting rod 503, thereby realizing that the loosening plate 206 revolves around the center of the outer cylinder 203, and reciprocates while rotating through the swivel 205.

[0026] Initially, the top ends of the six elastic telescopic shafts 303 are against the top ends of the corresponding guide grooves at the bottom of the guide ring 302. While the boss frame 201 drives the six tamping blocks 202 therein to rotate, the tamping blocks 202 drive the corresponding elastic telescopic shafts 303 to slide along the guide grooves at the bottom of the guide ring 302. Since the guide ring 302 cannot rotate at this time, the six tamping blocks 202 slide close to each other, and the elastic member A contracts under force. At the same time, the elastic telescopic shaft 303 contracts and slides along the inclined surface of the corresponding guide groove. When the elastic telescopic shaft 303 slides to the bottom end of the corresponding inclined surface of the guide groove and passes over it, the elastic telescopic shaft 303 is freed from the restriction of the guide groove, thereby enabling the tamping block 202 to move. At this time, the elastic member A is released, allowing the six tamping blocks 202 to slide quickly away from each other. During this process, the top end of the elastic telescopic shaft 303 is always against the bottom surface of the guide ring 302. Since the tamping block 202 is heavier, the tamping block 202 continues to slide under the influence of its own inertia after sliding quickly, and then the tamping block 202 passes over the outer wall of the outer cylinder 203 on the side close to the outer cylinder 203. When the tamping block 202 is located in the hole of the pile foundation hole, the tamping block 202 can contact and impact the hole wall, thereby making the hole wall denser and improving the stability of the pile foundation hole. Then the elastic member A contracts to drive the tamping block 202 to reset, and then the drill rod 1 continues to rotate, thereby causing the six tamping blocks 202 to drive the elastic telescopic shaft 303 therein to revolve, and the top end of the elastic telescopic shaft 303 continues to slide along the bottom surface of the guide ring 302. When the top end of the elastic telescopic shaft 303 slides to the next guide groove, the elastic telescopic shaft 303 can move, and the elastic telescopic shaft 303 is lifted upward and stuck in the next guide groove, and then the above steps are repeated to achieve continuous movement of the six tamping blocks 202.

[0027] As the drilling depth of the drill rod 1 increases, the outer cylinder 203 gradually follows the drill rod 1 into the borehole, and the excavated soil is transported to the outer cylinder 203 by the auger 304. Since the excavated soil is relatively dense, the soil gradually accumulates on the upper side of the guide ring 302 after entering the outer cylinder 203. As the soil gradually increases, part of the soil contacts the six soil-collecting plates 601, and the six soil-collecting plates 601 push the soil to the side close to the six compacting blocks 202, so that the soil can contact the loosening plate 206, and the loosening plate 206 can move the soil through the above-mentioned action. When the six tamping blocks 202 slide towards each other, some of the loosened soil can enter the gap between the tamping blocks 202 and the inner wall of the outer tube 203. When the drill rod 1 contacts the large stones in the soil layer, the large stones will exert force on the soil near its surface, causing defects in the hole wall of the pile drilling hole. At this time, repeating the above steps can push the soil between the tamping blocks 202 and the inner wall of the outer tube 203 and hit the defects in the hole wall, thereby supplementing the defects in the hole wall, thereby effectively preventing the collapse of the foundation soil layer. Example 2

[0028] like Figure 9-11As shown, the rain shield mechanism also includes an L-shaped rod 701, the top of the frame 207 is symmetrically slidably connected with the L-shaped rod 701, an elastic member B is provided between the L-shaped rod 701 and the frame 207, and the elastic member B is a compression spring. The L-shaped rod 701 is rotatably connected with a rotating shaft 7011, and the rotating shaft 7011 is rotatably connected with a rotating wheel 702 used in conjunction with the outer cylinder 203, and is fixed with a frustum 7021 used in conjunction with the outer cylinder 203. Four evenly distributed sliding grooves are provided in the rotating wheel 702, and elastic pins 703 are horizontally slidably connected in the four sliding grooves. Four evenly distributed hemispherical grooves are provided on the rotating shaft 7011, and four The sliding grooves are arranged in one-to-one correspondence with the four hemispherical grooves, and the elastic pin 703 is used in conjunction with the hemispherical grooves. A take-up wheel 704 is fixedly connected to the rotating shaft 7011, and a bottom plate 705 is fixedly connected to the bottom of the frame 207. A through hole is opened on the bottom plate 705, and a slider 706 is symmetrically slidably connected to the bottom plate 705. An elastic part C is arranged between the slider 706 and the frame 207, and the elastic part C is a compression spring. The slider 706 is hinged to the rain shield 208, and one end of a pull rope is fixedly connected to the take-up wheel 704, and a guide wheel group is symmetrically fixedly connected to the frame 207. The other end of the pull rope is wound around the guide wheel group and slides through the frame 207 to be fixed to one side of the slider 706.

[0029] like Fig.11 As shown, it also includes an elastic wedge block 801, and the elastic wedge block 801 is symmetrically slidably connected to the bottom of one side of the frame 207. A locking groove for use with the elastic wedge block 801 is opened on one side of the slider 706, and the elastic wedge block 801 is used to limit the position of the slider 706.

[0030] like Fig.11 As shown, it also includes a damping ring 901, and the damping ring 901 is sleeved on the pull rope. An extension rod 902 is symmetrically fixed to the bottom of the frame 207. The telescopic end of the extension rod 902 is fixed to an extrusion block 903 through a counterweight frame, and is fixed to the damping ring 901 through the counterweight frame. One side of the elastic wedge block 801 is rotatably connected to an L-shaped shaft, and one end of the L-shaped shaft movably passes through the frame 207 and is used in conjunction with the extrusion block 903. A stopper used in conjunction with the L-shaped shaft is symmetrically fixed to one side of the frame 207. When the extrusion block 903 contacts the L-shaped shaft, the elastic wedge block 801 can move.

[0031] like Fig.12 As shown, a locking rod 1001 is also included. The locking rod 1001 is rotatably connected to the frame 207. A locking pin is inserted through one end of the locking rod 1001. The locking pin is plugged into the frame 207. A slot for use with the locking rod 1001 is provided on the outer tube 203. The locking rod 1001 can lock the position of the outer tube 203.

[0032] Initially, the locking pin is inserted into the locking rod 1001 and the frame 207, the locking rod 1001 and the frame 207 are in a merged state, the locking rod 1001 is stuck in the slot of the outer cylinder 203, the elastic member C is in a released state, the two rain shields 208 are in a merged state, the two L-shaped shafts are located at one end of the outer side of the frame 207 and face vertically downward toward the foundation, the two rotating wheels 702 are in contact with the outer wall of the outer cylinder 203, and after the frame 207 is placed on the foundation surface, the staff first pulls out the locking pin and rotates the locking rod 1001 to disengage the locking rod 1001 from the slot of the outer cylinder 203, the elastic member B is in a contracted state, the drill rod 1 is started first to rotate the outer cylinder 203, and the outer cylinder 203 rotates in the same direction by friction with the two rotating wheels 702, and the rotating wheels 702 drive the four elastic pins 703 therein to rotate. The elastic force of pin 703 is relatively large, and the four elastic pins 703 squeeze the four hemispherical grooves of the rotating shaft 7011, so that the rotating shaft 7011 drives the take-up wheel 704 to rotate synchronously, and the take-up wheel 704 reels the pull rope, and the pull rope drives the corresponding slider 706 to slide, and the elastic part C is forced to shrink. At this time, the two rain shields 208 slide away from each other, and the slider 706 contacts and squeezes the inclined surface of the corresponding elastic wedge block 801 after sliding. The elastic wedge block 801 shrinks and slides under force. When the locking groove of the slider 706 is aligned with the elastic wedge block 801, the elastic wedge block 801 is disengaged from the restriction and released to slide into the locking groove. The elastic wedge block 801 limits the rain shield 208 through the slider 706, so that the two rain shields 208 no longer move, preventing the two rain shields 208 from blocking the drill rod 1 and the outer cylinder 203 from falling for rotary drilling.

[0033] When the pull rope is wound, friction is generated between the damping ring 901 and the pull rope, and the damping ring 901 is lifted upward due to the damping characteristics. The damping ring 901 drives the telescopic end of the corresponding extension rod 902 to extend through the counterweight frame, and the telescopic end of the extension rod 902 drives the extrusion block 903 to lift upward through the counterweight frame, so that the extrusion block 903 is away from the L-shaped shaft on the elastic wedge block 801. The L-shaped shaft is freed from the restriction to enable the elastic wedge block 801 to move. When the elastic wedge block 801 is stuck in the locking groove of the corresponding slider 706, the pull rope is stretched to the limit, thereby making the take-up wheel 704 unable to continue to rotate. The take-up wheel 704 drives the corresponding rotating shaft 7011 to stop rotating, and the elastic pin 703 cannot The hemispherical groove drives the rotating shaft 7011 to rotate. When the two rotating wheels 702 drive the elastic pin 703 therein to continue to rotate, the elastic pin 703 begins to shrink and jump due to the squeezing of the hemispherical groove, thereby preventing the staff from being unable to control the outer cylinder 203 to stop rotating in time, resulting in the breakage of the pull rope. Then the drill rod 1 drives the outer cylinder 203 to descend for rotary drilling. After the top end of the outer cylinder 203 descends, it passes over the two rotating wheels 702 and contacts the two cones 7021. As the outer cylinder 203 gradually descends, the top end of the outer cylinder 203 passes over the bottom end of the cone 7021 and no longer contacts the cone 7021. During this process, the elastic member B is gradually released, causing the two L-shaped rods 701 to gradually slide closer.

[0034] At this time, the pull rope is no longer reeled in, and the pull rope no longer applies friction to the damping ring 901. The weight of the counterweight frame and the extrusion block 903 is applied to the telescopic end of the extension rod 902. The telescopic end of the extension rod 902 is subjected to force to drive the corresponding damping ring 901 to slowly descend along the pull rope. When the top of the outer cylinder 203 is not completely sunk below the foundation soil layer, rainwater can be blocked by the outer cylinder 203 and cannot fall into the borehole, and the descending speed of the drill rod 1 and the outer cylinder 203 is slow. When the outer cylinder 203 is not completely sunk below the foundation soil layer, the two rain shields 208 will collide with the outer cylinder 203 when they are reset, causing damage. At this time, the L-shaped axis is vertically downward toward the foundation, and the extrusion block 903 cannot contact the corresponding L-shaped axis after it descends and resets, thereby making the two elastic wedge blocks 801 unable to move and keeping the two rain shields 208 away from each other.

[0035] When the top of the outer cylinder 203 is completely sunk below the foundation soil layer, the staff rotates the L-shaped shaft to make the L-shaped shaft contact with the top surface of the corresponding block. At this time, the extrusion block 903 can contact and squeeze the L-shaped shaft on the corresponding elastic wedge block 801 after it falls. The block provides support for the L-shaped shaft, so that the L-shaped shaft can slide horizontally. The L-shaped shaft is subjected to force to drive the elastic wedge block 801 to shrink and slide, and disengage from the locking groove of the slider 706. The slider 706 is free from the restriction and can move. The elastic part C is released to drive the slider 706 to reset, thereby causing the two rain shields 208 to slide, reset and merge. At this time, the two rain shields 208 are in contact with the outer walls of the drill rod 1 and the two telescopic rods 301. When it rains at the construction site, the two rain shields 208 can effectively prevent rainwater from entering the pile hole, causing rainwater to damage the hole wall of the pile hole.

[0036] When the drill rod 1 needs to be lifted out of the pile hole, the drill rod 1 drives the outer cylinder 203 to be lifted upward, and then the top end of the outer cylinder 203 contacts and squeezes the bottom surfaces of the two rain shields 208. The two rain shields 208 are forced to rotate upward with the connection of the sliders 706 as the center. Then the drill rod 1 and the outer cylinder 203 continue to be lifted upward. When the bottom end of the drill rod 1 passes over the two rain shields 208, the two rain shields 208 rotate downward and reset under the influence of their own gravity, thereby blocking rainwater again and preventing rainwater from entering the pile hole. Then the top end of the outer cylinder 203 contacts and squeezes the surfaces of the two cones 7021, so that the two The L-shaped rods 701 slide away from each other, and then the drill rod 1 moves horizontally to the waste soil collection point to clean the waste soil on it and in the outer cylinder 203, and then the drill rod 1 is moved horizontally to reset, so that the outer cylinder 203 contacts and squeezes the surfaces of the two wheels 702, so that the two L-shaped rods 701 slide away from each other again, the elastic member B contracts again, and then the above steps are repeated to perform rotary drilling on the pile hole. In the subsequent rotary drilling process, there is no need to manually rotate the L-shaped shaft. The two rain shields 208 can be automatically reset by squeezing the L-shaped shaft through the squeezing block 903, thereby reducing the manual operation steps and completing the work of the entire device.

[0037] An operating method of a pile drilling processing device for building foundation construction comprises the following steps: S1: Place the frame 207 on the foundation, pull out the lock pin, start the rotary drilling machine, rotate the drill rod 1, and then rotate the take-up wheel 704 to tighten the pull rope. The pull rope drives the rain shield 208 to slide through the slider 706, and lifts the extrusion block 903 upward, and then the drill rod 1 falls to start rotary drilling; S2: When the top of the outer cylinder 203 enters the drill hole, the loosening plate 206 breaks up the soil in the outer cylinder 203, making it easier for the soil to enter the gaps between the tamping blocks 202 and the inner wall of the outer cylinder 203; S3: When the tamping blocks 202 rotate, the telescopic ends of the elastic telescopic shafts 303 slide along the guide grooves at the bottom of the guide ring 302, so that the tamping blocks 202 slide close to each other, and then the telescopic ends of the elastic telescopic shafts 303 are separated from the guide grooves, and the elastic member A is released to drive the tamping blocks 202 to slide, and the soil hits the hole wall; S4: After the squeezing block 903 falls, it contacts and squeezes the L-shaped shaft, thereby causing the elastic wedge block 801 to disengage from the locking groove of the slider 706, and then causing the rain shield 208 to slide back to its original position, shielding the drill hole to prevent rainwater from entering the drill hole.
