Description

Technical Field

[0001] This invention relates to the field of auxiliary technology in building construction, and in particular to an auxiliary device for drilling and grouting pile construction. Background Technology

[0002] Drilled cast-in-place piles refer to pile holes formed in the foundation soil on the engineering site by means of mechanical drilling, steel pipe soil displacement or manual excavation. The installation of guide pipes is one of the procedures, which requires inserting a guide pipe into the hole and then connecting another guide pipe to the inserted guide pipe.

[0003] Chinese Patent Publication No. CN117569749A discloses an auxiliary device for bored pile construction, relating to the field of building construction auxiliary devices. This invention provides an auxiliary device for bored pile construction that enables precise docking of guide pipes, facilitating their placement into the hole. It includes a support frame, a first limiting plate, and a driving assembly. The driving assembly is located on top of the support frame and drives the first limiting plate. The driving assembly and the first limiting plate are slidably connected. The support frame has a docking mechanism for precisely docking the guide pipes. The docking mechanism includes symmetrically arranged fixing plates. While the aforementioned patent enables precise docking of the guide pipes, it cannot pre-treat the guide pipe joint by removing residue before docking. This makes it difficult to tighten the guide pipe joint during the subsequent docking process, affecting the precise docking. Manual removal is cumbersome and reduces docking efficiency.

[0004] This invention aims to solve the problems existing in the above-mentioned patents. To this end, it proposes an auxiliary device for bored pile construction that can remove the residue at the guide pipe joint before precise docking, which is easy to operate and improves docking efficiency. Summary of the Invention

[0005] To overcome the shortcomings of the aforementioned patents, which, although capable of precise docking of conduits, cannot pre-treat by removing residue from the conduit joint before docking, making it difficult to tighten the conduit joint during subsequent docking and affecting the precision of docking, and which, when cleaned manually, are cumbersome and reduce docking efficiency, this invention provides a drilling and grouting pile construction auxiliary device that can remove residue from the conduit joint before precise docking, making it easy to operate and improving docking efficiency.

[0006] This invention is achieved through the following technical solution:

[0007] A drilling pile construction auxiliary device includes a mobile vehicle and crossbars symmetrically fixed to the inner side of the mobile vehicle. A hole for a guide pipe to pass through is opened in the middle of the mobile vehicle. Arc-shaped positioning plates are symmetrically slidably fitted between the crossbars. An electric push rod is fixed to the inner side of the mobile vehicle, and the telescopic end of the electric push rod is fixedly connected to the arc-shaped positioning plate. The device also includes an arc-shaped guide rail, a scraper, a movable plate, a contact rod, a drive assembly, a positioning assembly, a clamping assembly, and a support assembly.

A scraper block is slidably connected to the inner side of the arc-shaped guide rail. A movable plate is fixed to the bottom of the scraper block, and a contact rod is fixed to the bottom of the movable plate. A drive assembly is provided on the arc-shaped positioning plate. The drive assembly is used to drive the contact rods on the front and rear sides to move away from each other. The contact rod drives the scraper block to move through the movable plate. The scraper block moves under the action of the arc-shaped guide rail so that the scraper block can scrape off the residue at the conduit joint. The clamping assembly is installed on the moving vehicle to clamp another conduit that is connected. The support assembly is installed on the moving vehicle to support and limit the conduit placed in the hole.

[0008] Further explanation: The drive assembly includes a guide frame fixed to the arc-shaped positioning plate. A slotted plate is symmetrically slidably mounted on the guide frame. The inner side of the slotted plate is slidably connected to the contact rod to drive the contact rod to move. A bidirectional lead screw is rotatably connected to the guide frame. The threads on the front and rear sides of the bidirectional lead screw are opposite. The bidirectional lead screw is threadedly connected to the slotted plate. A servo motor is installed inside the guide frame. The output shaft of the servo motor is driven by the bidirectional lead screw through a synchronous belt assembly.

[0009] Further explanation: The positioning component includes guide rods fixed to the front and rear sides of the mobile vehicle, a contact frame slidably mounted on the guide rods, a slide rod slidably connected to the contact frame, a wedge-shaped frame fixed to the end of the slide rod to position the guide tube, a connecting spring connecting the end of the slide rod to the contact frame, and a cylinder I fixed to the mobile vehicle, the end of the telescopic rod of cylinder I being fixedly connected to the contact frame.

[0010] Further explanation: The clamping assembly includes a support frame fixed to the rear side of the mobile vehicle, with arc-shaped clamps symmetrically rotatably connected to the support frame for clamping and fixing the docking conduits, and a dual-axis motor symmetrically mounted on the support frame, with the output shaft of the dual-axis motor fixedly connected to the shaft of the arc-shaped clamp.

[0011] Further explanation: The support assembly includes fixed seats symmetrically fixed to the front and rear sides of the mobile vehicle. Each fixed seat is equipped with a cylinder II. An L-shaped support plate is fixed to the end of the telescopic rod of the cylinder II for supporting the guide tube in the insertion hole.

[0012] Further explanation: The auxiliary equipment for bored pile construction also includes a rotating component. The rotating component includes a fixed frame fixed to the inside of the mobile vehicle. A movable frame is slidably mounted on the fixed frame. The side of the movable frames that are close to each other on the left and right sides is an inclined surface. A drive roller is rotatably connected to the bottom of the movable frame to drive the joint to rotate. A drive motor is installed inside the movable frame. The output shaft of the drive motor is connected to the drive roller through a bevel gear transmission. Return springs are symmetrically connected between the movable frame and the fixed frame.

[0013] To further explain, the auxiliary equipment for bored pile construction also includes ball bearings that are rotatably connected to an L-shaped support plate at uniform intervals, which are used to reduce the friction between the ball bearing and the guide pipe.

[0014] Further explanation: The auxiliary equipment for bored pile construction also includes a rubber pad fixed to the inner side of the arc-shaped clamp plate, which is used to increase the friction between the arc-shaped clamp plate and the guide pipe.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. First, move the device above the ground access hole position. Then, lower the guide tube into the hole. The L-shaped support plate supports the guide tube. Then, activate the electric push rod to move the scraper to contact the guide tube joint. Activate the servo motor to move the scraper to remove the residue at the guide tube joint. Then, the wedge frame positions the other guide tube. The positioned guide tube moves to dock with the guide tube in the hole. In this way, the scraper can remove the residue at the guide tube joint before precise docking. The operation is convenient and improves docking efficiency.

[0017] 2. Under the action of the arc-shaped clamp, whenever the upper conduit comes into contact with the lower conduit, the arc-shaped clamp can clamp and fix the upper conduit, and then the conduits can start to connect. This can prevent the conduits from shaking and affecting the connection, thus completing the precise connection of the conduits.

[0018] 3. Under the action of the drive roller, whenever the guide tubes are connected, the rotation of the drive roller can drive the joint to rotate and tighten. Tightening the joint can fix the two guide tubes together, eliminating the need for operators to manually tighten the joint, making operation convenient and further improving the connection efficiency.

[0030] Example: An auxiliary device for bored pile construction, please refer to [link / reference]. Figures 1-5As shown, the device includes a mobile carriage 1 and crossbars 2 symmetrically fixed to the upper inner side of the mobile carriage 1.

Two scraper blocks 6 are slidably connected to the inner sides of the right-side arc-shaped guide rails 5. Movable plates 7 are fixed to the bottom of the four scraper blocks 6. Contact rods 71 ​​are fixed to the bottom of the left and right movable plates 7 at positions far apart from each other. A drive assembly is provided on the arc-shaped positioning plate 3. The drive assembly is used to drive the contact rods 71 ​​on the front and rear sides to move in a direction far apart from each other. The contact rods 71 ​​drive the scraper blocks 6 to move through the movable plates 7. The scraper blocks 6 move under the action of the arc-shaped guide rails 5 so that the scraper blocks 6 can scrape off the residue at the conduit joint. The clamping assembly is installed on the moving carriage 1. When the clamping assembly is in operation, the clamping assembly can clamp another connected conduit. The support assembly is installed on the moving carriage 1. When the support assembly is in operation, the support assembly can support and limit the conduit placed in the hole.

[0031] Please see Figure 3 and Figure 4 As shown, the drive assembly includes a guide frame 8, a slotted plate 81, a bidirectional lead screw 82, and a servo motor 83. Guide frames 8 are fixedly connected to the arc-shaped positioning plates 3 on both the left and right sides. Slotted plates 81 are symmetrically slidably mounted on the guide frames 8. The inner side of the slotted plate 81 is slidably connected to the contact rod 71. When the slotted plate 81 moves, it can drive the contact rod 71 to move. The bidirectional lead screw 82 is rotatably connected between the upper parts of the front and rear sides of the guide frame 8. The threads of the bidirectional lead screw 82 are opposite on the front and rear sides. The bidirectional lead screw 82 is threaded to the lower part of the slotted plates 81 on the front and rear sides. Servo motors 83 are installed on the lower part of the inner front side of the guide frames 8 on both the left and right sides. The output shafts of the servo motors 83 on both the left and right sides are connected to the front side of the bidirectional lead screws 82 on the left and right sides respectively through a synchronous belt assembly.

[0032] Please see Figure 5As shown, the positioning assembly includes a guide rod 9, a contact frame 91, a cylinder I 92, a slide rod 93, a wedge frame 94, and a connecting spring 95. Guide rods 9 are fixedly connected to the lower parts of the front and rear sides of the moving vehicle 1. Contact frames 91 are slidably mounted on the guide rods 9 on both the front and rear sides. Slide rods 93 are slidably connected to the upper parts of the contact frames 91 on both the front and rear sides. Wedge frames 94 are fixedly connected to the ends of the slide rods 93 on both the front and rear sides that are close to each other. When the conduit is placed for docking, the wedge frame 94 can position the conduit. Connecting springs 95 are connected between the ends of the slide rods 93 on both the front and rear sides that are far apart from each other and the upper parts of the contact frames 91 on both the front and rear sides. Cylinders I 92 are fixedly connected to the upper parts of the front and rear sides of the moving vehicle 1. The telescopic rod ends of the cylinders I 92 on both the front and rear sides are fixedly connected to the lower parts of the contact frames 91 on both the front and rear sides.

[0033] Please see Figure 6 As shown, the clamping assembly includes a support frame 10, arc-shaped clamping plates 101, and a dual-axis motor 102. The support frame 10 is fixedly connected to the upper rear side of the moving vehicle 1. Two arc-shaped clamping plates 101 are symmetrically rotatably connected to the upper front side of the support frame 10. When the arc-shaped clamping plates 101 swing inward and contact the guide tube, the arc-shaped clamping plates 101 can clamp and fix the docked guide tube. The dual-axis motor 102 is symmetrically installed on the upper front side of the support frame 10. The output shafts on the upper and lower sides of the dual-axis motor 102 are fixedly connected to the shafts of the upper and lower arc-shaped clamping plates 101, respectively.

[0034] Please see Figure 6 As shown, the support assembly includes a fixed seat 11, a cylinder II 111, and an L-shaped support plate 112. Fixed seats 11 are symmetrically fixed to the upper part of the front and rear sides of the mobile vehicle 1. A cylinder II 111 is installed on each of the four fixed seats 11. An L-shaped support plate 112 is fixed to the end of the telescopic rod of each of the four cylinders II 111. When the L-shaped support plate 112 moves to contact the guide tube in the insertion hole, the L-shaped support plate 112 can support the guide tube in the insertion hole.

[0035] First, move the mobile vehicle 1 above the ground access hole, ensuring the hole on the mobile vehicle 1 aligns with the hole in the ground. Then, use a lifting machine to lower the guide tube into the hole. Simultaneously, activate the front and rear cylinders II 111. The extension rods of the front and rear cylinders II 111 extend, causing the front and rear L-shaped support plates 112 to move closer together. The front and rear L-shaped support plates 112 are positioned on the left and right sides of the guide tube. Then, close cylinders II 111. As the guide tube continues to descend, the fixing ring on the guide tube contacts and is limited by the L-shaped support plates 112, thus limiting the guide tube's position. Next, activate cylinder I 92. The extension rod of cylinder I 92 shortens, causing the front and rear contact frames 91 to move closer together. The contact rod 71, via the connecting spring 95, moves the front and rear... The two sliding rods 93 move towards each other, causing the front and rear wedge-shaped frames 94 to move towards each other. When the front and rear contact frames 91 move and contact the guide tube lowered into the hole, cylinder I 92 is closed, and the electric push rod 4 is activated. The telescopic rod of the electric push rod 4 extends, causing the left and right arc-shaped positioning plates 3 to move towards each other. The arc-shaped positioning plates 3, through the arc-shaped guide rail 5, cause the left and right scraper blocks 6 to move towards each other. When the left and right scraper blocks 6 contact the guide tube joint, the electric push rod 4 is closed, the arc-shaped positioning plates 3 stop moving, and the left and right arc-shaped positioning plates 3 clamp and fix the guide tube. The servo motor 83 is then activated to rotate forward. The servo motor 83 drives the bidirectional lead screw 82 to rotate through the synchronous belt assembly. The bidirectional lead screw 82 drives the front and rear straight-hole plates 81 to move away from each other. The straight-hole plates 81, through the contact rod 71, drive the front and rear movable plates 7 to move away from each other. The movable plates 7 drive the front and rear scraper blocks 6 to move away from each other. The scraper blocks 6 slide within the arc-shaped guide rail 5. The movement of the scraper blocks 6 scrapes away the residue at the conduit joint. When the scraper blocks 6 move to their maximum stroke within the arc-shaped guide rail 5, the servo motor 83 is activated to reverse, causing the front and rear scraper blocks 6 to move closer to each other and reset. Then, the electric push rod 4 is activated to drive the left and right arc-shaped positioning plates 3 to move away from each other and reset. The left and right scraper blocks 6 are then reset and disengaged from the conduit joint. At this point, the next section to be connected is lifted by the lifting machine. The guide tube is moved above the wedge frame 94 and lowered. As the guide tube moves downward, it contacts the inclined surfaces of the front and rear wedge frames 94. The guide tube presses against the front and rear wedge frames 94, causing them to move away from each other. The wedge frames 94 drive the sliding rod 93 to move, and the connecting spring 95 is stretched. As the guide tube continues to move downward, it disengages from the inclined surfaces of the wedge frames 94 and contacts the vertical surfaces of the wedge frames 94. The wedge frames 94 stop moving, and the front and rear wedge frames 94 then position the guide tube, ensuring that the downward-moving guide tube precisely aligns with the guide tube inside the hole. When the bottom end of the guide tube aligns with the top end of the guide tube inside the hole, the lifting machine is shut down. At this time, the dual-axis motor 102 is started to rotate, causing the left and right arc-shaped clamps 101 to swing towards each other.The left and right curved clamps 101 clamp and fix the upper conduit. Then, the joint is twisted to rotate and fix the upper and lower conduits together. Because the curved clamps 101 clamp and fix the upper conduit, it prevents the conduit from shaking and affecting the docking, thus completing the precise docking of the conduits. Then, the dual-axis motor 102 is started to drive the left and right curved clamps 101 to swing and reset in a direction away from each other. The curved clamps 101 release the conduit. Then, the cylinder II 111 is started to drive the L-shaped support plate 112 to move and reset. The L-shaped support plate 112 resets and disengages from the fixing ring of the conduit. The lifting machine can then continue to lower the docked conduit into the hole. After the docked conduit is lowered, the cylinder I 92 is started to drive the front and rear contact frames 91 to move and reset in a direction away from each other, which also causes the wedge frame 94 to move and reset. In this way, the scraper 6 can first remove the residue at the conduit joint before precise docking, which is convenient and improves docking efficiency.

[0036] Please see Figure 7 As shown, the auxiliary equipment for bored pile construction also includes a rotating assembly installed on the mobile vehicle 1. The rotating assembly includes a fixed frame 12, a movable frame 121, a return spring 122, a drive roller 123, and a drive motor 124. Fixed frames 12 are fixedly connected to the upper part of both the left and right sides of the mobile vehicle 1. Movable frames 121 are slidably mounted on both fixed frames 12. The side of the movable frames 121 that is close to each other is an inclined surface. The bottom of the movable frames 121 that is close to each other is rotatably connected to the drive roller 123. When the drive roller 123 rotates, it can drive the joint to rotate. The bottom of the movable frames 121 on both sides is equipped with a drive motor 124. The output shafts of the drive motors 124 on both sides are respectively connected to the upper part of the drive rollers 123 on both sides through bevel gear transmission. The side of the movable frames 121 that is far apart from each other is symmetrically connected to the fixed frames 12 on both sides.

[0037] When the guide tube is lowered, it contacts the inclined surface of the movable frame 121. The guide tube squeezes the left and right movable frames 121 and moves them away from each other. The return spring 122 is compressed. As the guide tube continues to move downward, it loses contact with the inclined surface of the movable frame 121, the wedge frame 94 stops moving, and the guide tube moves downward and contacts the drive roller 123. When the second guide tube moves downward to dock, the connector of the guide tube contacts the left and right drive rollers 123. At this time, the drive motor 124 is started. The drive motor 124 drives the drive roller 123 to rotate through the bevel gear transmission. The rotation of the drive roller 123 drives the connector of the guide tube to rotate and tighten. The rotation of the connector fixes the two guide tubes together. Then the drive motor 124 is turned off, and the drive roller 123 stops rotating. When the docked guide tube continues to be lowered, the guide tube loses contact with the drive roller 123. Due to the action of the return spring 122, the left and right movable frames 121 move towards each other to reset. The movable frame 121 drives the left and right drive rollers 123 to move towards each other to reset. In this way, there is no need for operators to manually tighten the connectors, making the operation convenient and further improving docking efficiency.

[0038] Please see Figure 8 As shown, the auxiliary equipment for bored pile construction also includes ball bearings 13. Seven ball bearings 13 are evenly spaced and rotated on the side of the L-shaped support plates 112 on both sides. The ball bearings 13 can reduce the friction between the ball bearing and the guide pipe.

[0039] Please see Figure 9 As shown, the auxiliary equipment for bored pile construction also includes rubber pads 14. Rubber pads 14 are fixed to the inner sides of the four arc-shaped clamps 101. The rubber pads 14 can increase the friction between the arc-shaped clamps 101 and the guide pipe.

[0040] When the L-shaped support plate 112 moves, it drives the ball bearing 13 to move. The ball bearing 13 moves and contacts the guide tube during the lowering process. The ball bearing 13 reduces the friction between the L-shaped support plate 112 and the guide tube. In this way, the L-shaped support plate 112 can be prevented from directly rubbing against the guide tube, which would cause wear and affect subsequent use, thereby ensuring the service life of the L-shaped support plate 112.

[0041] When the left and right curved clamps 101 swing toward each other, the curved clamps 101 drive the left and right rubber pads 14 to swing toward each other. The rubber pads 14 contact the upper conduit, and the curved clamps 101 clamp and fix the conduit through the rubber pads 14. The rubber pads 14 increase the friction between the curved clamps 101 and the conduit, so that the curved clamps 101 can clamp the conduit more firmly for docking.

[0042] Finally, it is necessary to note that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the scope of protection of the present invention; any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention are all within the scope of protection claimed by the present invention.
