Description

Technical Field

[0001] This invention belongs to the field of pile hole cleaning technology, and particularly relates to a pile hole cleaning device with good cleaning effect. Background Technology

[0002] In the construction process, in order to ensure the stability of the foundation and reduce the impact of the looseness of the slag on the stability of the foundation, pile holes are drilled and steel cages are placed in the pile holes and concrete is poured to form foundation piles. This provides stable support for the foundation and ensures the stability of the building construction. At the same time, the pile holes can transfer the building load to the hard soil or rock layer underground, reducing the risk of collapse. In addition, the pile foundation can effectively anchor the foundation and prevent settlement or slippage.

[0003] During the excavation of pile holes, in order to ensure the bearing capacity and stability of the pile foundation, the slag at the bottom of the pile is cleaned. However, during the cleaning process using a rotary drilling slag removal bucket, the bottom of the pile hole is often difficult to clean due to the complex conditions and the presence of unbroken rocks at some bottoms. Furthermore, it is difficult to remove gravel and other particles during the cleaning process, which affects the cleaning effect of the rotary drilling slag removal bucket. Summary of the Invention

The sealing cap can seal the position of the bolt to reduce bolt rusting.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by incorporating a rotary drilling assembly, the slag at the bottom of the pile hole can be quickly shoveled into the cylinder by a shovel plate during the cleaning process. The cylinder then carries the slag out for further processing. If rocks at the bottom of the hole affect the cleaning effect, a second electric push rod can move the connecting plate and push the shovel plate to change its angle, reducing the resistance during rotation. Simultaneously, a second hinged seat can push the breaking rod to extend and crush the rocks, ensuring thorough cleaning, reducing the impact of the slag at the bottom of the hole on subsequent construction, and ensuring the stability of the pile foundation.

[0016] 2. In this invention, by providing an outlet component inside, the design enables the installation ring to move via a first electric push rod during the slag removal process. Simultaneously, the cooperation between the cover plate and the installation ring during its vertical movement allows for upward suction of water, accelerating the inward flow of slag scraped by the shovel and drawing water from the outer wall into the cylinder, thus increasing the speed of slag flow into the cylinder and improving slag removal efficiency. It also encourages some slag to flow from the outside into the cylinder, ensuring effective slag removal. Furthermore, when the cylinder moves upward, the guide shell and mesh plate prevent water from directly entering the cylinder and reduce the impact of water flowing into the cylinder.

[0017] 3. In this invention, by incorporating a flap assembly, the design enables the rotating plate to block the opening of the mounting plate, reducing the outflow of slag from the cylinder. During the process of the shovel plate feeding a large amount of slag into the cylinder, the slag's pressure on the rotating plate causes it to flip upwards, increasing the opening size of the mounting plate and ensuring the slag can enter the cylinder. Furthermore, the slag's flow within the cylinder is guided by the protrusion on the top surface of the rotating plate, causing it to flow upwards and further preventing slag from flowing out from the top opening. Additionally, as the mounting ring moves upwards, the increased water flow causes the rotating plate to rotate upwards, ensuring the water flows smoothly into the cylinder.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10 This invention provides a technical solution: a pile hole cleaning device with good cleaning effect, including a cylinder 4 and a cover-opening module 2; a connecting cylinder 1, which is disposed above the cylinder 4 for connecting a rotary drilling rig; and the cover-opening module 2 is known in the technical field and therefore not described in detail herein, and also includes: The rotary drilling assembly 6 includes a mounting plate 601 located at the bottom of the cylinder 4, and the mounting plate 601 has a fan-shaped opening for feeding material, through which the slag can be fed into the cylinder 4. A rotating plate 604 is located on the bottom surface of the mounting plate 601, and a rotating shaft 606 is provided on the top surface of the rotating plate 604. The rotating plate 604 is rotatably connected to the mounting plate 601 through the rotating shaft 606, and the rotating plate 604 corresponds to the fan-shaped opening at the bottom end of the mounting plate 601. The shovel plate 607 is located on the edge of the rotating plate 604 and is hinged to the rotating plate 604. The rotation of the cylinder 4 can drive the shovel plate 607 to shovel the slag at the bottom into the cylinder 4 through the opening provided by the mounting plate 601. It also includes: a connecting sleeve 5, which is cylindrical and installed on the bottom edge of the cylinder 4; Connecting seat 609 is disposed on the top surface of mounting plate 601 and is rotatably connected to connecting sleeve 5; The connecting buckle 602 is set on the top surface of the mounting plate 601, and the top of the connecting buckle 602 is connected to the connecting hook at the bottom of the opening module 2. By separating the connecting hook at the bottom of the opening module 2 from the connecting buckle 602, the mounting plate 601 can rotate around the connecting seat 609 as the axis point, thereby opening the bottom of the cylinder 4. Limiting strip 603 is installed on the top surface of rotating plate 604 and is slidably installed in the groove opened on the bottom surface of mounting plate 601; It also includes: an extrusion block 605, which is installed at the edge of the rotating plate 604. As the cylinder 4 rotates, the extrusion block 605 can slide and extrude the slag at the bottom and squeeze both sides of the slag phase. The fixing block 610 is set on the bottom surface of the mounting plate 601, and one side of the fixing block 610 is provided with a groove corresponding to the rotating plate 604. The fixing block 610 can limit the rotating plate 604 and prevent the rotating plate 604 from rotating excessively. Limiting block 608 is installed on one side of rotating plate 604, and limiting block 608 is provided on both the upper and lower sides of shovel plate 607. The swing angle of shovel plate 607 can be limited by limiting block 608. The breaking rod 611 is a rod with a breaking head at one end. The breaking rod 611 is slidably installed in the groove opened on the back of the shovel plate 607. By extending the breaking rod 611, it can break the rock in the pile hole. It also includes: a sliding frame 615, which is a long strip used to connect multiple crushing rods 611, and the sliding frame 615 is slidably disposed inside the shovel plate 607; The second hinge seat 616 is installed on one side of the sliding frame 615 and is located on the back of the shovel plate 607. The connecting plate 612 is hinged at one end to the second hinge seat 616. The movement of the connecting plate 612 can push the shovel plate 607 to swing and push the crushing rod 611 to extend and retract. The first hinge seat 613 is hinged to the connecting plate 612 on one side, and the telescopic end of the second electric push rod 614 is installed on one side of the first hinge seat 613. The first hinge seat 613 is moved by the second electric push rod 614, which in turn moves the connecting plate 612.

[0031] The specific implementation is as follows: During the cleaning process of the bottom end of the pile hole, the connecting cylinder 1 is connected to the output end of the rotary drilling rig, so that the cylinder 4 can be rotated by the rotary drilling rig, and the mounting plate 601 and the rotating plate 604 can be rotated. At the same time, the surface of the shovel plate 607 is a smooth plane and the back of the bottom end is a beveled surface. When the shovel plate 607 contacts the bottom of the pile hole, the shovel plate 607 and the rotating plate 604 are resisted and rotate relative to the mounting plate 601. This causes the rotating plate 604 to move away from the fan-shaped opening of the mounting plate 601, and one side of the rotating plate 604 abuts against the fixing block 610, thereby preventing the rotating plate 604 from rotating further relative to the cylinder. This allows the rotating plate 604 to rotate synchronously with the mounting plate 601 and the cylinder 4. During the rotation, the slag at the bottom of the pile hole can be shoveled into the cylinder 4 by the shovel plate 607. Furthermore, during the rotation of the cylinder 4, the slag at the edge of the hole wall can be moved and squeezed by the arc-shaped outer wall of the squeezing block 605, thereby squeezing the slag towards the hole wall to strengthen the hole wall and reduce the risk of hole wall collapse. At the same time, the slag located inside the squeezing block 605 can move inward under the shielding effect of the squeezing block 605, thereby ensuring that the shovel plate 607 can effectively shovel it into the cylinder 4. Furthermore, if rocks are encountered during the process of cleaning the bottom of the hole with the shovel plate 607, the first hinge seat 613 can be moved by the second electric push rod 614, and then the second hinge seat 616 can be moved by the connecting plate 612. At the same time, the shovel plate 607 can be moved by the push of the connecting plate 612, and the shovel plate 607 can be made to swing to a certain extent, so that the shovel plate 607 abuts against the limiting block 608 on one side, thereby changing the angle between the shovel plate 607 and the bottom of the hole, reducing the angle, thereby reducing the resistance to forward movement, and ensuring that the cylinder 4 can descend smoothly. Furthermore, after the connecting plate 612 pushes the shovel plate 607 to swing, the second electric push rod 614 continues to push, which can drive the second hinge seat 616 and the sliding frame 615 to move, thereby driving the crushing rod 611 to move and causing the crushing rod 611 to extend from the front end of the shovel plate 607. Then, during the rotation of the shovel plate 607, the rock can be squeezed and crushed by the conical protrusion at the front end of the crushing rod 611, thereby reducing the impact of the rock on the slag removal and ensuring the slag removal effect. Furthermore, after the rock crushing is completed, the second electric push rod 614 can drive the shovel 607 to reset, thereby increasing the angle between the shovel 607 and the bottom of the hole, so as to ensure that the slag at the bottom of the hole is quickly removed by the shovel 607 and ensure the efficiency of slag removal.

[0032] The outlet component 3 includes a top cover 302 located at the top of the cylinder 4, and the connecting cylinder 1 is installed on the top surface of the top cover 302; The guide shell 301 is installed on the top surface of the top cover 302, and the top cover 302 has an opening corresponding to the guide shell 301. The guide shell 301 can guide the water flow from the opening of the top cover 302 during the rotation of the cylinder 4. The screen plate 303 is set on one side of the opening of the guide shell 301, and one side of the screen plate 303 is an arc-shaped surface. The screen plate 303 can reduce the amount of slag flowing out of the cylinder 4 with the water flow. It also includes: a mounting ring 308, which is disposed inside the cylinder 4, and a first limiting frame 307 is provided inside the mounting ring 308; The first electric push rod 304 has its telescopic end fixedly connected to the top surface of the mounting ring 308, and the first electric push rod 304 is located on the top surface of the top cover 302. The telescopic end of the first electric push rod 304 passes through the top cover 302, and the mounting ring 308 can be moved by the first electric push rod 304. It also includes: a cover plate 305, which is disposed on the top surface of the mounting ring 308, and an airbag 306 is provided on the top surface of the cover plate 305, which can improve the buoyancy of the cover plate 305 in water. The slide rod 309 is installed on the bottom surface of the cover plate 305 and slides within the first limiting frame 307. The bottom end of the slide rod 309 is provided with an end cap to prevent the slide rod 309 from sliding out of the first limiting frame 307.

[0033] The specific implementation is as follows: During the process of the cylinder 4 driving the shovel plate 607 to clean the slag at the bottom of the hole, the first electric push rod 304 can drive the mounting ring 308 to move upward. During the upward movement, the top surface of the mounting ring 308 can contact the surface of the cover plate 305. The cover plate 305 is circular and its diameter is larger than the opening provided in the mounting ring 308. Thus, the opening of the mounting ring 308 can be blocked by the cover plate 305. During the upward movement of the mounting ring 308 and the cover plate 305, it can act as a piston and drive the water flow inside the cylinder 4 to flow upward. At the same time, it can drive the water flow to be sucked in from the bottom of the cylinder 4, thereby accelerating the flow of the slag shoveled by the shovel plate 607 inward and sucking some slag chunks into the cylinder 4, thereby ensuring the cleaning effect of the device. Furthermore, when the first electric push rod 304 drives the mounting ring 308 to move downward, the top surface of the mounting ring 308 separates from the bottom surface of the cover plate 305, thereby exposing the fan-shaped opening provided by the mounting ring 308. As a result, when the mounting ring 308 moves downward, the water flow can flow from the inside of the mounting ring 308 to the upper side, thereby preventing the mounting ring 308 from pushing the water flow downward. Furthermore, during the rotation of the cylinder 4, the water flows along the outer wall of the guide shell 301, while the water inside the cylinder 4 can flow out of the guide shell 301. The guide shell 301 is spiral-shaped, and the water flowing on the outer wall of the guide shell 301 can guide the water flowing out of the interior, thereby accelerating the water flow out of the guide shell 301 and improving the effect of the upward movement of the mounting ring 308 to a certain extent. Furthermore, when the water flows outward from the guide shell 301, the mesh plate 303 can block some of the sludge in the water flow, thereby reducing the amount of sludge discharged from the guide shell 301 along with the water flow. Furthermore, during the upward movement of the cylinder 4, the guide shell 301 can reduce the flow of water into the cylinder 4 and the slag inside the cylinder 4 being washed away. Also, since one side of the mesh plate 303 is curved, it can guide the downward flow of water to a certain extent, thereby further preventing the water from directly rushing into the cylinder 4 when the cylinder 4 moves upward.

[0034] Flip plate assembly 7 includes a rotating plate 701, a cover plate 702 on the top surface of the rotating plate 701, and a connecting shaft 703 on the bottom surface of the rotating plate 701. Mounting base 704, the top of mounting base 704 is provided with a groove corresponding to connecting shaft 703, and mounting base 704 is installed in the groove opened on the top surface of mounting plate 601; It also includes: a second limiting frame 705, which is disposed on one side of the mounting base 704, and the top of the second limiting frame 705 is provided with a plug corresponding to the top groove of the mounting base 704, and the connecting shaft 703 is wrapped by the mounting base 704 and the second limiting frame 705. The baffle 706 is installed on one side of the second limit frame 705, and one side of the baffle 706 is arc-shaped. The top surface of the baffle 706 is in contact with the bottom surface of the rotating plate 701. The baffle 706 can guide and block the water flow that is rushing towards the second limit frame 705. It also includes: bolt 708, which is located in a groove opened on one side of the stop block 706, and the second limit bracket 705 is fixed to the mounting base 704 by bolt 708; The sealing cover 707 is located in the groove opened on one side of the stop block 706, and a sealing structure is provided between the sealing cover 707 and the stop block 706. The sealing cover 707 can seal the position of the bolt 708 to reduce the rusting of the bolt 706.

[0035] The specific implementation is as follows: When installing the rotating plate 701, the connecting shaft 703 at the bottom of the rotating plate 701 can be slid into the groove opened at the top of the mounting base 704. Then, the second limiting frame 705 is installed on one side of the mounting base 704 and fixed with bolts 708. At the same time, the groove at the top of the second limiting frame 705 is connected to the protrusion at the top of the mounting base 704, and the other side of the connecting shaft 703 can be limited by the second limiting frame 705, thereby limiting the connecting shaft 703 and allowing the connecting shaft 703 to rotate in the groove formed by the second limiting frame 705 and the top of the mounting base 704. Furthermore, during the process of slag entering the cylinder 4 along the surface of the shovel plate 607, if there is a lot of slag, the slag will push the rotating plate 701 up from the bottom surface of the rotating plate 701, thereby increasing the opening exposed by the mounting plate 601 and avoiding clogging of the opening, which would affect the slag cleaning efficiency. Furthermore, after the slag enters the cylinder 4, the water flow and the accumulation of slag cause the slag inside to move. When the slag moves to the surface of the rotating plate 701, the top of the rotating plate 701 is raised, allowing the slag and water flow to move upward, thereby preventing the slag from falling into the opening of the mounting plate 601 and affecting the subsequent entry of slag. At the same time, the rotating plate 701 is provided with a baffle 702 to reduce the impact of slag entering the connection of the rotating plate 701. Furthermore, as the installation ring 308 moves upward, the flow rate of water entering the cylinder 4 increases, which also causes the rotating plate 701 to rotate upward, thereby ensuring that the water and slag smoothly enter the cylinder 4. The block 706 on one side of the second limit frame 705 can block the water flowing towards the second limit frame 705.
