Description

Technical Field

[0001] This invention relates to the field of pile foundation cleaning technology, specifically to a hole cleaning device for anti-overturning cast-in-place piles. Background Technology

[0002] Photovoltaic pile foundations are the basic project for photovoltaic projects, serving as civil engineering works during construction. Photovoltaic technology has many advantages: for example, it has no mechanical moving parts; besides sunlight, it does not require any other "fuel"; and it can work under both direct and oblique sunlight. Today, its application in power generation has spread all over the world, from powering automatic parking meters and rooftop solar panels to large-scale solar power centers. Mountain photovoltaic projects are among the largest and most significant photovoltaic projects, contributing to the sustainable development of energy.

[0003] Photovoltaic pile foundation construction is the most important foundation in photovoltaic project construction. At the same time, in the current stage of mountain photovoltaic projects in China, pile foundation construction is the process with the highest safety risk, the greatest construction difficulty, and the greatest difficulty in quality control.

[0004] Mountain photovoltaic projects involve a large number of concrete cast-in-place pile foundations, and the construction is all carried out in mountainous areas. Most of the mountain slopes are steep, which makes the process of cleaning the pile foundation holes complicated, time-consuming, and labor-intensive. As a result, before the pile foundation is ready for pouring, due to the long interval between the next construction process or external factors such as weather, the drilled pile foundation holes may collapse, thus affecting the construction and pouring quality of the mountain photovoltaic pile foundation.

[0005] Furthermore, existing processes are prone to technical problems when cleaning the foundation holes of photovoltaic piles in mountainous areas, such as difficulty in cleaning soil and debris and poor cleaning effect. This leads to a significant extension of the construction period, which is not conducive to the smooth progress of photovoltaic projects. The removal of waste residue from the foundation holes of photovoltaic piles and the cleaning of the removed waste residue have become urgent problems to be solved in the construction of photovoltaic pile foundations in mountainous areas. Summary of the Invention

[0006] To address the aforementioned issues, it is necessary to provide a hole-cleaning device for anti-overturning cast-in-place piles, addressing the problems inherent in existing technologies.

[0007] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows: A hole-cleaning device for anti-overturning foundation cast-in-place piles includes a pile driver and a hole-cleaning mechanism mounted thereon.

[0009] The height adjustment mechanism includes a vertical adjustment frame that is slidably nested on the limiting slide block, the vertical adjustment frame having an adjustment groove, and the limiting slide block penetrating the adjustment groove; The vertical adjustment frame is equipped with sliding rollers at both the upper and lower ends, and the sliding rollers are in close sliding connection with the inner wall of the movable groove. A fastening ring is installed at the top of the vertical adjustment frame, and the fastening ring is fixedly connected to the traction steel wire. The lower part of the vertical adjustment frame is equipped with a fastening compartment, and the fastening compartment has a pre-set fastening slot.

[0010] The locking mechanism includes a limiting sleeve fixedly installed in the middle of the vertical adjustment frame, and an electric telescopic rod is provided through the limiting sleeve. The fixed end of the electric telescopic rod is fixed to the top of the vertical adjustment frame. A motor cover is installed at the bottom of the electric telescopic rod, and a servo motor is connected inside the motor cover. A drive shaft is installed on the output end of the servo motor, and the motor cover moves up and down with the extension and retraction of the electric telescopic rod.

[0011] The installation mechanism includes an installation chamber that is fastened to the fastening slot, and an outer cover plate is installed on the outer side of the installation chamber; The lower end of the outer cover is fixed to the mounting bracket; The installation compartment is equipped with a rotating seat, and the top of the rotating seat is provided with a snap-fit ​​slot. The snap-fit ​​slot and the drive shaft are in a nested snap-fit ​​connection structure. The rotating base has toothed columns distributed on it, and toothed plates are provided on both sides of the toothed columns. The toothed plates and the toothed columns are meshed together.

[0012] The back of the toothed plate has multiple horizontal sliding grooves, and each groove is equipped with a limit sliding rod. A limit ring is installed at the end of the limiting slide rod; An annular retaining plate is installed at the end of the inner wall of the chute, and the annular retaining plate cooperates with the limiting ring to limit the toothed plate. The toothed plate forms a nested sliding limit connection structure with the limiting slide rod through the sliding groove; The limiting slide rod is fixedly installed on the inner wall of the installation chamber.

[0013] The integrated control module is electrically connected to the drive motor, and the integrated control module consists of a power supply module and a control module structure. A drive gear is installed on the output end of the drive motor, and the drive gear is meshed with the guide gear. The guide gear forms a rotating structure with the slag suction pipe through a docking bearing, and the slag suction pipe forms a rotating connection with the inner pipe through a docking bearing. The lower end of the inner tube is threaded.

[0014] The air compressor module includes an equipment compartment located on the side of the pile driver, an air compressor is installed inside the equipment compartment, and an air outlet pipe is installed at the output end of the air compressor; The top of the equipment compartment is fitted with a hinged, reversible access door, and the bottom of the equipment compartment is equipped with wheels.

[0017] Compared with the prior art, the present invention has the following beneficial effects.

[0018] Firstly, the suction pipe connected to the inner pipe can directly guide the residue in the pile foundation hole. After the residue is transported into the inner pipe through the suction pipe, it directly reaches the blower. The air pressure forms a circulating airflow, and the waste residue in the pile foundation hole is discharged through the slag discharge pipe installed on the blower, forming an efficient residue cleaning channel. The pile foundation hole is cleaned immediately after the pile foundation hole is opened, avoiding the phenomenon of delayed cleaning of the pile foundation hole leading to the extension of the subsequent processing period, and further accelerating the progress of the photovoltaic project.

[0019] Secondly, by turning on the drive motor, the drive gear is turned on, which drives the guide gear and the inner tube installed on it to rotate. In conjunction with the docking bearing, the slag suction pipe is fixed while the inner tube is rotated. The suction pipe installed on the inner tube will also rotate. When the suction pipe rotates, the slag removal seat installed at its lower end will quickly disperse and clean the residue in the pile foundation hole, making it easier to discharge the residue.

[0020] Thirdly, the vertical adjustment frame nested on the limiting slide can be adjusted to adjust the height of the vertical adjustment frame. The height of the slag discharge mechanism and the slag suction mechanism can be adjusted according to the height of the vertical adjustment frame, which can adapt to pile foundation holes of different depths.

[0021] Fourth, the arc-shaped paddle can quickly guide the residue when the slag removal head rotates, thereby dispersing and breaking up some of the residue that has clumped together. This not only allows the residue to be removed quickly, but also prevents large pieces of residue from clogging the transmission pipeline, enabling faster and more thorough residue cleaning.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a foundation pile cleaning device for preventing overturning, including a pile driver 1 and a cleaning mechanism 2 disposed thereon. The pile driver 1 includes a control chamber 101 and a limiting frame 102. The limiting frame 102 has a movable groove 106, and the cleaning mechanism 2 is disposed in the movable groove 106. The movable groove 106 on the limiting frame 102 and the cleaning mechanism 2 disposed in the movable groove 106 will not affect the operation of the pile driver 1 when the cleaning mechanism 2 is not installed. When the cleaning mechanism 2 is installed, the pile driver 1 needs to stop operating to maintain the safety of the construction site. like Figure 1 As shown, the control compartment 101 is equipped with an overall control module, which is the control module for the pile driver 1. The pile driver 1 is a commonly used pile driving equipment in existing mountain photovoltaic projects. A height adjustment frame 103 is installed on the limit frame 102 and slidably nested therewith. A drive pile 104 is installed on the height adjustment frame 103. A detachable pile driving auger 105 is installed at the lower end of the drive pile 104. The pile driving auger 105 can be moved down to open the pile foundation hole. After the opening is completed, the pile foundation hole is removed, and a lot of residue will remain in the new pile foundation hole, which can be cleaned up immediately.

[0027] like Figure 3As shown, a height adjustment frame 103 is provided on the limit frame 102. A linkage platform 107 is installed on the side of the height adjustment frame 103 close to the movable groove 106. A traction steel wire 27 is fixedly installed on the linkage platform 107. A threading roller 28 is installed at the top of the movable groove 106 where the traction steel wire 27 passes through. The traction steel wire 27 is fixed at the linkage platform 107 and passes through the threading roller 28 for height adjustment. The linkage platform 107 adjusts its height according to the height adjustment frame 103, and adjusts the length of the traction steel wire 27 on both sides of the threading roller 28.

[0028] like Figure 2 , Figure 3 , Figure 4 As shown, the hole cleaning mechanism 2 includes a limiting slide 29 fixed to the inner wall of the movable groove 106 and a height adjustment mechanism 21 disposed on the limiting slide 29. The height adjustment mechanism 21 is equipped with a locking mechanism 22 and an installation mechanism 23. The installation mechanism 23 is connected to a slag discharge mechanism 24. like Figure 5 , Figure 6 , Figure 7 As shown, the height adjustment mechanism 21 includes a vertical adjustment frame 2101 that is slidably nested on the limiting slide 29. The vertical adjustment frame 2101 has an adjustment groove 2102. The limiting slide 29 and the adjustment groove 2102 are connected. The adjustment groove 2102 improves the stability of the vertical sliding between the limiting slide 29 and the vertical adjustment frame 2101. The upper and lower ends of the vertical adjustment frame 2101 are equipped with auxiliary rollers 2103. The auxiliary rollers 2103 are in close sliding connection with the inner wall of the movable groove 106. The operation of the auxiliary rollers 2103 is smoother when the vertical adjustment frame 2101 adjusts the vertical height. like Figure 3 , Figure 7 As shown, a fastening ring 2104 is installed at the top of the vertical adjustment frame 2101. The fastening ring 2104 is connected to the traction steel wire 27. The two ends of the traction steel wire 27 are respectively fixedly installed on the linkage platform 107 and the fastening ring 2104. That is, when the linkage platform 107 moves down, the vertical adjustment frame 2101 with the fastening ring 2104 installed moves up, and when the linkage platform 107 moves up, the vertical adjustment frame 2101 with the fastening ring 2104 installed moves down. In this way, the height of the vertical adjustment frame 2101 is adjusted according to the depth of the pile foundation hole.

[0029] like Figure 6As shown, the locking mechanism 22 includes a limiting sleeve 2202 fixedly installed in the middle of the vertical adjustment frame 2101. An electric telescopic rod 2201 is installed through the limiting sleeve 2202. The fixed end of the electric telescopic rod 2201 is fixed to the top of the vertical adjustment frame 2101. A motor cover 2203 is installed at the bottom of the electric telescopic rod 2201. A servo motor 2204 is connected inside the motor cover 2203. A drive shaft 2205 is installed on the output end of the servo motor 2204. The motor cover 2203 moves up and down with the extension and retraction of the electric telescopic rod 2201. The servo motor 2204 is installed inside the motor cover 2203 and can be adjusted according to the height of the motor cover 2203, thereby adjusting the height of the drive shaft 2205 on the output end of the servo motor 2204, which facilitates driving and adjusting the mounting mechanism 23.

[0030] like Figure 11 , Figure 14 , Figure 16 As shown, the slag discharge mechanism 24 includes a mounting frame 2401 and a blower 2409 installed inside it. A comprehensive control module 2402 is installed on the mounting frame 2401. A slag extraction pipe 2412 connected to the blower 2409 is provided at the bottom of the mounting frame 2401. A slag discharge pipe 2413 is installed at one end of the blower 2409. A docking bearing 2405 is installed on the outer wall of the slag suction pipe 2412. A guide gear 2406 is provided on the outer wall of the docking bearing 2405. An inner pipe 2407 is connected to the inner wall of the guide gear 2406. A drive gear 2404 meshes with the side of the guide gear 2406. The output shaft of the drive motor 2403 is connected to the central shaft of the drive gear 2404. The integrated control module 2402 is electrically connected to the drive motor 2403. The drive gear 2404 is installed on the output end of the drive motor 2403. The drive gear 2404 and the guide gear 2406 are meshed. The guide gear 2406 forms a rotating structure with the slag suction pipe 2412 through the docking bearing 2405. The slag suction pipe 2412 forms a rotating connection with the inner pipe 2407 through the docking bearing 2405. The meshing of the drive gear 2404 and the guide gear 2406 can drive the rotation of the inner pipe 2407. At the same time, the fixed slag suction pipe 2412 can still discharge loose stones and broken soil. The integrated control module 2402 consists of a power supply module and a control module. The integrated control module 2402 controls the operation of the drive motor 2403, which can be turned on according to the construction status to achieve thorough cleaning of the pile foundation hole. The other end of the blowpipe 2409 is connected to a conduit 2410, and an air inlet valve 2411 is installed on the conduit 2410. When the air inlet valve 2411 is open, the conduit 2410 is open; when the air inlet valve 2411 is closed, the conduit 2410 is closed.

[0031] like Figure 4 , Figure 6 , Figure 8 As shown, a fastening compartment 2105 is installed at the lower part of the vertical adjustment frame 2101. The fastening compartment 2105 has a pre-set fastening groove 2106. The installation mechanism 23 includes an installation compartment 2302 that is fastened to the fastening groove 2106. The installation compartment 2302 is fastened into the fastening groove 2106 to achieve the initial installation of the installation mechanism 23. An outer cover plate 2301 is installed on the outer side of the installation compartment 2302. The outer cover plate 2301 protects the internal components of the installation compartment 2302. A block is provided at the lower end of the outer cover plate 2301 to fix it to the installation frame 2401. The outer cover plate 2301 is connected to the installation frame 2401 through the block to realize the flexible movement and installation of the installation frame 2401. like Figure 6 , Figure 8 , Figure 9 As shown, a rotating seat 2303 is provided inside the installation compartment 2302. A snap-fit ​​groove 2304 is provided at the top of the rotating seat 2303. The snap-fit ​​groove 2304 and the drive shaft 2205 are nested and engaged. When the drive shaft 2205 moves down, it engages with the snap-fit ​​groove 2304, so that the snap-fit ​​groove 2304 rotates with the rotation of the drive shaft 2205. The rotating seat 2303 has toothed columns 2305 distributed on it, and toothed plates 2307 are provided on both sides of the toothed columns 2305. The lower end of the inner tube 2407 is provided with a first thread 2408. The toothed plates 2307 and the toothed columns 2305 are meshed. When the snap-fit ​​groove 2304 rotates, the toothed columns 2305 on the rotating seat 2303 rotate and mesh with the toothed plates 2307 on both sides to push them out. At this time, the toothed plates 2307 can be unfolded to lock with the snap-fit ​​chamber 2105, preventing the mounting bracket 2401 connected to the outer cover plate 2301 from being displaced. like Figure 6 , Figure 9 , Figure 10As shown, the back of the toothed plate 2307 has multiple horizontal grooves 2308. Each groove 2308 contains a limiting rod 2306. A limiting ring 2310 is installed at the end of each limiting rod 2306. An annular retaining plate 2309 is installed at the end of the inner wall of each groove 2308. The annular retaining plate 2309 and the limiting ring 2310 cooperate to limit the toothed plate 2307. The toothed plate 2307 forms a nested sliding limiting connection structure with the limiting rods 2306 through the grooves 2308. The limiting rods 2306 are fixedly installed on... On the inner wall of the installation compartment 2302, the mutual limiting between the annular locking plate 2309 and the limiting ring 2310 can prevent the toothed plate 2307 from falling out while it unfolds, and drive the toothed plate 2307 more stably, ensuring that the toothed plate 2307 can fit against the inner wall of the fastening compartment 2105 to achieve the locking function. When it is necessary to remove it, the reverse rotation of the drive shaft 2205 drives the toothed plate 2307 to retract, and the electric telescopic rod 2201 runs upward to retract the motor cover 2203, so that the installation mechanism 23 can be removed.

[0032] like Figure 11 , Figure 15 As shown, the conduit 2410 is connected to the air compressor module 25. The air compressor module 25 includes an equipment compartment 2501 located on the side of the pile driver 1. An air compressor 2502 is installed inside the equipment compartment 2501. An air outlet pipe 2504 is installed at the output end of the air compressor 2502. The air outlet pipe 2504 is connected to the conduit 2410 to transmit the air pressure of the air compressor 2502 to the blower 2409. The top of the equipment compartment 2501 is fitted with a hinged, reversible access door 2503 for easy maintenance, and the bottom of the equipment compartment 2501 is fitted with wheels 2505 for easy movement. A limiting rail 2506 is provided on the side of the equipment compartment 2501. An insert plate 2507 is installed inside the limiting rail 2506, and the insert plate 2507 and the limiting rail 2506 are nested and slidably connected. A magnetic plate is installed at the top of the insert plate 2507, which magnetically connects to the inner wall of the limiting rail 2506. The bottom end of the insert plate 2507 is a pointed tip 2508, and a handle 2509 is connected to the insert plate 2507 near the pointed tip 2508. On sloping terrain, the equipment compartment 2501 needs to be secured to prevent it from tipping over. The handle is used for securing the equipment compartment. 2509 drives the tip 2508 on the insert plate 2507 to impact the ground. The tip 2508 penetrates the ground directly, while the limiting rail 2506 limits the impact trajectory of the tip 2508, quickly and accurately fixing the equipment compartment 2501. When the equipment compartment 2501 does not need to be fixed, hold the handle 2509 to drive the tip 2508 on the insert plate 2507 away from the fixed area, and then push the insert plate 2507 upward to make it slide within the limiting rail 2506 and magnetically fix it to the inner wall of the limiting rail 2506.

[0033] like Figure 12 As shown, a slag suction mechanism 26 is provided at the lower end of the slag discharge mechanism 24. The slag suction mechanism 26 includes a suction pipe 2601 connected to the inner pipe 2407. The suction pipe 2601 is a multi-segment assembly structure. The two ends of the suction pipe 2601 are respectively provided with a second thread 2602 and a third thread 2603. The second thread 2602 and the third thread 2603 are threaded to each other. The connection of the second thread 2602 and the third thread 2603 can assemble the suction pipe 2601. The corresponding number of suction pipes 2601 are installed according to the depth of the photovoltaic pile foundation hole to more thoroughly clean the photovoltaic pile foundation hole. The second thread 2602 and the first thread 2408 are threaded to each other. The connection of the second thread 2602 and the first thread 2408 can install the uppermost suction pipe 2601 on the inner pipe 2407 for connection. like Figure 12 , Figure 13 As shown, a tubular slag-cleaning seat 2604 is provided at the end of the suction pipe 2601. A fourth thread 2608 is provided at the top of the slag-cleaning seat 2604. The fourth thread 2608 is threadedly connected to the third thread 2603. The fourth thread 2608 is installed in conjunction with the suction pipe 2601 through the third thread 2603. The mating of the fourth thread 2608 and the third thread 2603 installs the slag-cleaning seat 2604 on the end of the suction pipe 2601. A flared slag-cleaning head 2605 is provided on the slag-cleaning seat 2604. The slag-cleaning head 2605 has multiple slag inlets 2. 606. A lever 2607 is installed at the interval of the slag inlet 2606 on the outer wall of the slag cleaning head 2605. Both the lever 2607 and the slag inlet 2606 are arranged in a circular array on the slag cleaning head 2605. The lever 2607 has an arc-shaped structure. When the slag cleaning head 2605 rotates, the lever 2607 can quickly guide the slag, thereby dispersing and breaking up some of the clumps of slag. This can not only quickly remove the slag, but also prevent large pieces of slag from clogging the transmission pipeline, and enable faster and more thorough slag cleaning.

[0034] Working principle: Start the pile driver 1, drive the pile 104 to move at the upper limit of the limit frame 102 along with the height adjustment frame 103, and the pile driving auger 105 close to the ground to open the photovoltaic pile foundation hole. After the opening is completed, remove the pile driving auger 105 and start the cleaning work of the pile foundation hole. During cleaning, move the air compressor module 25 parked on the side to the corresponding position and fix the equipment compartment 2501. When fixing, hold the handle 2509 and drive the tip 2508 on the insert plate 2507 to impact the ground. The tip 2508 penetrates the ground directly. The limit rail 2506 limits the impact trajectory of the tip 2508, and fixes the equipment compartment 2501 quickly and accurately. Then connect the air outlet pipe 2504 to the conduit 2410 to facilitate the subsequent transmission of air pressure. Then, the slag discharge mechanism 24 is removed, and the mounting frame 2401 is moved to the corresponding position. The height adjustment frame 103 is activated to drive the linkage platform 107 to adjust the height. The linkage platform 107 drives the vertical adjustment frame 2101 to adjust the height through the traction steel wire 27 to ensure that the vertical adjustment frame 2101 is compatible with the air compressor module 25 to be installed. After the height adjustment of the vertical adjustment frame 2101 is completed, the mounting frame 2401 is pushed to connect the mounting mechanism 23 into the fastening chamber 2105. After the mounting chamber 2302 is fully connected with the fastening chamber 2105, the electric telescopic rod 2201 is activated to engage the drive shaft 2205 of the servo motor 2204 output end in the motor cover 2203 into the fastening slot 2304. When the fastening slot 2304 and the drive shaft 2205 are completely locked, the servo motor 2204 is activated to drive the rotating seat 2303 to rotate. The toothed column 2305 rotates and engages with the toothed plates 2307 on both sides, at which point the toothed plates 2307 can unfold and lock with the fastening chamber 2105, preventing displacement of the mounting bracket 2401 connected to the outer cover plate 2301. At the same time, the mutual limiting between the annular clamping plate 2309 and the limiting ring 2310 can prevent the toothed plates 2307 from falling out while unfolding. After the toothed plates 2307 are fully unfolded, the servo motor 2204 stops running, and the initial installation of the mounting bracket 2401 is completed. When adjusting the height of the mounting bracket 2401, the height adjustment bracket 103 is also activated to drive the linkage platform 107 to adjust the height. The linkage platform 107 drives the vertical adjustment bracket 2101 to adjust the height through the traction steel wire 27. Install the corresponding number of suction pipes 2601 according to the depth of the photovoltaic pile foundation hole. Connect the second thread 2602 and the third thread 2603 to assemble the suction pipe 2601. Install the slag removal seat 2604 on the last suction pipe 2601. When installing, connect the fourth thread 2608 and the third thread 2603 and screw them together. The vertical adjustment frame 2101 is lowered to place the slag removal seat 2604 and the air intake pipe 2601 inside the pile foundation hole. The air compressor 2502 and the drive motor 2403 are turned on. The drive gear 2404 on the output end of the drive motor 2403 meshes with the guide gear 2406. The guide gear 2406 drives the inner tube 2407 to rotate, and the slag removal seat 2604 installed on the air intake pipe 2601 can then rotate. When the slag removal seat 2604 rotates, the arc-shaped prying block 2607 also rotates inside the pile foundation hole. The prying block 2607 quickly guides the residue while dispersing and breaking it apart. The residue is separated into clumps, which not only allows for quick removal of the residue but also prevents large pieces of residue from clogging the transmission pipe, enabling faster and more thorough residue cleaning. The residue enters the suction pipe 2601 through the slag inlet 2606. The airflow is quickly guided by pressure, and the airflow in the pile foundation hole picks up the remaining loose soil and gravel, causing them to tumble. The loose soil and gravel are then transported through the suction pipe 2601 into the blower 2409 and discharged through the slag discharge pipe 2413 to a wide area for accumulation. After cleaning, the pile driver 1 can be disassembled and moved for subsequent repeated pile driving and hole cleaning work.
