Description

Technical Field

[0001] The present 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 foundation 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 foundation 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 foundation pile drilling hole. When large stones appear in a concentrated manner, the soil layer around the hole wall of the foundation pile drilling hole will loosen and the soil layer will collapse, which can easily lead to construction accidents. When concrete is poured subsequently, 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

[0021] 2.

The outer wall of the boss frame 201 is fixedly connected to an outer cylinder 203. The six tamping blocks 202 are all slidably connected to the outer cylinder 203. A loosening mechanism is provided in the outer cylinder 203. The loosening mechanism includes a support shaft 204, the inner wall of the outer cylinder 203 is symmetrically connected to the support shaft 204, a swivel 205 is fixedly provided on the support shaft 204, the outer wall of the swivel 205 is rotatably connected to the loosening plate 206, and a rain shield mechanism is provided on the lower side of the outer cylinder 203. The rain shield mechanism includes a frame 207, the outer cylinder 203 is used in conjunction with the frame 207, and a rain shield 208 is symmetrically slidably connected to the frame 207. The rain shield 208 can prevent rainwater from entering the pile hole and causing damage to the wall of the pile hole.

[0037] like Figures 1-6As 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 the plane where the rotary drilling device does not rotate by bolts. The telescopic end of the telescopic rod 301 is fixedly connected to a guide ring 302, and the guide ring 302 is rotatably connected to the boss frame 201. A number 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 dragon 304 is fixed to the middle part of the drill rod 1, and the screw dragon 304 is used to transport soil to the upper side of the guide ring 302.

[0038] like Figure 3-Figure 7 As 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 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 surface of the gear ring 401 and the gear.

[0039] 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 the 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 can enable the connecting rod 503 to drive the loosening plate 206 to swing back and forth.

[0040] 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.

[0041] When it is necessary to drill a foundation pile, the drill rod 1 is rotated to be perpendicular to the foundation through the rotary drilling machine in the existing equipment (the rotary drilling machine is existing technology 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 down and starts 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 swings back and forth while rotating through the swivel 205.

[0042] When the cam 303 is in contact with the guide rail 302, the top ends of the six elastic telescopic shafts 303 are in contact with the top ends of the guide grooves corresponding to the bottom ends of the guide ring 302. When the cam 301 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 ends 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 is forced to shrink. At the same time, the elastic telescopic shaft 303 shrinks and slides along the inclined surfaces of the corresponding guide grooves. When the elastic telescopic shaft 303 slides to the bottom ends of the inclined surfaces of the corresponding guide grooves and passes over them, the elastic telescopic shaft 303 is freed from the restriction of the guide grooves, thereby enabling the tamping blocks 202 to move. At this time, the elastic member A is released, causing the six tamping blocks 202 to slide quickly away from each other. During this process, the top ends of the elastic telescopic shafts 303 are always in contact with the bottom surfaces 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 approaches the side of the outer cylinder 203 and passes over the outer wall of the outer cylinder 203. When the tamping block 202 is located in the hole of the pile foundation, the tamping block 202 can contact and impact the hole wall, thereby making the hole wall more compact and improving the stability of the pile foundation hole. Then the elastic part 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.

[0043] 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 tamping blocks 202, so that the soil can contact the loosening plate 206. The loosening plate 206 can move the soil through the above action. When the six tamping blocks 202 slide close to each other, some of the loosened soil can enter the gap between the tamping blocks 202 and the inner wall of the outer cylinder 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 foundation pile drilling. At this time, repeating the above steps can push the soil between it and the inner wall of the outer cylinder 203 through the tamping block 202 and hit the defects in the hole wall, thereby filling the defects in the hole wall and effectively preventing the collapse of the foundation soil layer. Example 2

[0044] like Figures 9-11As shown, the rain shield mechanism also includes an L-shaped rod 701, and 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. The elastic member B is a compression spring. The L-shaped rod 701 is rotatably connected to the rotating shaft 7011, and the rotating shaft 7011 is rotatably connected to the 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 the four The sliding grooves are arranged in one-to-one correspondence with the four hemispherical grooves, and the elastic pins 703 are used in conjunction with the hemispherical grooves. A take-up wheel 704 is fixed to the rotating shaft 7011, and a base plate 705 is fixed to the bottom of the frame 207. A through hole is opened on the base plate 705, and a slider 706 is symmetrically slidably connected to the base plate 705. An elastic part C is arranged between the slider 706 and the frame 207. The elastic part C is a compression spring. The slider 706 is hinged to the rain shield 208. One end of the pull rope is fixed to the take-up wheel 704, and a guide wheel group is symmetrically fixed 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.

[0045] like Figure 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.

[0046] like Figure 11 As shown, it also includes a damping ring 901, a damping ring 901 is provided 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 the extrusion block 903 through the 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, one end of the L-shaped shaft is movable through the frame 207, and is used in conjunction with the extrusion block 903, and a stop block 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 be moved.

[0047] like Figure 12 As shown, it also includes a locking rod 1001, which is rotatably connected to the frame 207. A locking pin is inserted into one end of the locking rod 1001, and the locking pin is plugged into the frame 207. A card slot for use with the locking rod 1001 is provided on the outer tube 203, and the locking rod 1001 can lock the position of the outer tube 203.

[0048] Initially, the lock pin is inserted into the lock rod 1001 and the frame 207, the lock rod 1001 and the frame 207 are in a merged state, the lock 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 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 lock pin and rotates the lock rod 1001 to disengage the lock rod 1001 from the slot of the outer cylinder 203, the elastic member B is in a contracted state, the drill rod 1 is first started to rotate the outer cylinder 203, and the outer cylinder 203 rotates in the same direction by friction with the two wheels 702, and the wheels 702 drive the four elastic pins 703 therein to rotate. When the lock groove of 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, thereby preventing the two rain shields 208 from moving and preventing the two rain shields 208 from blocking the drill rod 1 and the outer cylinder 203 from falling for rotary drilling.

[0049] 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 its 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 disengaged 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 When the rotating shaft 7011 is driven to rotate by the hemispherical groove and 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 descending, the top end of the outer cylinder 203 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.

[0050] 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.

[0051] When the top of the outer cylinder 203 is completely sunk below the foundation soil layer, the staff rotates the L-shaped shaft so that the L-shaped shaft contacts 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 foundation pile hole, causing rainwater to damage the hole wall of the foundation pile hole.

[0052] When the drill rod 1 needs to be lifted out of the foundation 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 point of the slider 706 as the center of the circle, and 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 foundation pile hole. Then the top end of the outer cylinder 203 contacts and squeezes the surfaces of the two cones 7021, thereby making 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 area 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 part B contracts again, and then the above steps are repeated to perform rotary drilling of the foundation 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 with the squeezing block 903, which reduces the manual operation steps and completes the work of the entire device.

[0053] An operating method of a pile drilling device for building foundation construction comprises the following steps:

[0054] 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. Then the drill rod 1 is lowered and the rotary drilling work begins;

[0055] S2: After the top end 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;

[0056] 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, causing the tamping blocks 202 to slide closer to each other. Then, the telescopic ends of the elastic telescopic shafts 303 disengage from the guide grooves, and the elastic member A is released, driving the tamping blocks 202 to slide and impact the soil on the hole wall.

[0057] S4: After the squeezing block 903 falls, it contacts and squeezes the L-shaped shaft, thereby disengaging the elastic wedge block 801 from the locking groove of the slider 706, and then the rain shield 208 slides back to its original position, shielding the drill hole and preventing rainwater from entering the drill hole.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
