Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a pile foundation hole construction device. Background Technology

[0002] A foundation pile hole is a hole drilled for cast-in-place concrete piles to reinforce underground foundations and improve the load-bearing capacity and seismic resistance of building foundations.

[0003] During the construction of pile foundation holes, it is generally necessary to drill holes of the appropriate size in the ground in advance through the pile hole drill. Then, a lifting device such as a crane is used to lift the pipe that needs to be inserted into the hole. Then, the crane's traction chain is slowly lowered, and the traction chain drives the pipe to move down, so that the pipe can slowly move into the pre-dug hole. During the process of moving the pipe down, the pipe is prone to misposition and deviation. Therefore, during construction, it is necessary to continuously straighten the pipe, which is quite troublesome.

[0004] Therefore, it is necessary to provide a new pile foundation hole construction equipment to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a pile foundation hole construction device.

[0006] The pile foundation hole construction equipment provided by this utility model includes a base and two clamping devices. A driving device is installed on the base, and the two clamping devices are both installed on the driving device. The two clamping devices can be raised and lowered by the driving device. Each clamping device is provided with multiple movable ends that can move simultaneously toward the center of the clamping device. Each movable end of the upper clamping device is equipped with a mounting frame, and rollers are movably installed in the mounting frame. Each movable end of the lower clamping device is equipped with a clamping block.

[0007] Preferably, the clamping device includes a mounting plate, a clamping assembly, and two connecting blocks. A mounting ring is fixedly connected to the bottom edge of the mounting plate, and the two connecting blocks are respectively fixedly connected to both sides of the mounting ring. The top end of the clamping assembly is positioned above the mounting plate.

[0008] Preferably, the clamping assembly includes a rotating component, an internal gear ring, and multiple moving components. The internal gear ring is movably connected to the inner wall of the mounting ring. The multiple moving components are circumferentially and evenly installed on the bottom of the mounting plate. The rotating component is installed on the bottom of the mounting ring and is connected to one of the moving components.

[0009] Preferably, the movable component includes a gear, a rack, and a limiting block. The gear is movably connected to the bottom of the mounting plate and meshes with an internal gear ring. The limiting block has a T-shaped structure and is fixedly installed on the inner wall of a through groove at the bottom of the mounting ring. The rack is movably inserted into the through groove at the bottom of the mounting ring, and a through groove for the limiting block to pass through is provided on the rack. The rack meshes with the gear, and a connecting frame is fixedly connected to one end of the rack. The top wall of the connecting frame is located above the mounting plate.

[0010] Preferably, the rotating component includes a U-shaped mounting bracket and a first motor. The top of the mounting bracket is fixedly connected to the bottom of the mounting ring, the first motor is fixedly installed inside the mounting bracket, and the output end of the first motor is fixedly connected to one of the gears.

[0011] Preferably, the ends of the multiple connecting frames in the upper clamping device are respectively fixedly connected to multiple mounting frames, and the ends of the multiple connecting frames in the lower clamping device are respectively fixedly connected to multiple clamping blocks.

[0012] Preferably, the driving device includes a rotating rod, a guide rod, and two support frames. Both support frames are fixedly connected to the top of the base. The rotating rod is movably connected to one support frame, and the guide rod is fixedly connected to the other support frame.

[0013] Preferably, a second motor is provided at the top of the rotating rod, the second motor is installed on the top of the support frame, and the output end of the second motor is fixedly connected to the end of the rotating rod.

[0014] Compared with related technologies, the pile foundation hole construction equipment provided by this utility model has the following beneficial effects:

[0015] When using this device, the upper clamping device is activated, causing multiple mounting brackets and rollers to come together. The rollers then contact the outer surface of the pipe. As the pipe, lifted by the traction chain, moves downward, the rollers rotate. When the pipe is near the top and positioned at the rollers, the rollers separate, and the pipe is clamped to the outer wall by multiple clamping blocks on the lower clamping device. At this point, the lifting device lowers the two clamping devices, and the pipe gradually moves downward, facilitating pipe installation. This device, with its multiple rollers and clamping blocks, positions the pipe, preventing it from shifting during installation. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1-6 ,in, Figure 1 This is a structural schematic diagram of the pile foundation hole construction equipment provided by this utility model; Figure 2 for Figure 1 A partial side view of the structure shown is a schematic diagram. Figure 3 for Figure 1 The diagram shows the structure of the clamping device. Figure 4 for Figure 3 A schematic diagram of the bottom of the structure shown; Figure 5 for Figure 3 A bottom-view structural diagram of the structure shown; Figure 6 for Figure 4 The diagram shows the structure of the mounting ring and the limiting block.

[0025] In the specific implementation process, such as Figures 1-6As shown, the device includes a base 1 and two clamping devices. A drive unit is mounted on the base 1, and both clamping devices are mounted on the drive unit and can be raised and lowered via the drive unit. Each clamping device has multiple movable ends that can move simultaneously toward the center of the clamping device. Mounting brackets 2 are mounted on the multiple movable ends of the upper clamping device, and rollers 3 are movably mounted within the mounting brackets 2. Clamping blocks 4 are mounted on the multiple movable ends of the lower clamping device. Activating the upper clamping device causes the mounting brackets 2 and rollers 3 to move closer together. Roller 3 contacts the outer surface of the pipe. As the pipe is lowered by the traction chain, roller 3 rotates. When the pipe is near the top and located at multiple rollers 3, the multiple rollers 3 are separated from each other and clamped to the outer wall of the pipe by multiple clamping blocks 4 on the clamping device located below. At this time, the lifting device moves the two clamping devices down, and the pipe also gradually moves down, which facilitates the installation of the pipe. The device, through the multiple rollers 3 and multiple clamping blocks 4, plays a positioning role for the pipe, making it less likely for the pipe to shift during the installation process.

[0026] The clamping device includes a mounting plate 5, a clamping assembly, and two connecting blocks 7. A mounting ring 6 is fixedly connected to the bottom edge of the mounting plate 5. The two connecting blocks 7 are respectively fixedly connected to both sides of the mounting ring 6. The top of the clamping assembly is located above the mounting plate 5. The clamping assembly includes a rotating component, an internal gear ring 9, and multiple moving components. The internal gear ring 9 is movably connected to the inner wall of the mounting ring 6. The multiple moving components are evenly installed circumferentially at the bottom of the mounting plate 5. The rotating component is installed at the bottom of the mounting ring 6 and is connected to one of the moving components. The moving component includes a gear 8, a rack 10, and a limiting block 12. The gear 8 is movably connected to the bottom of the mounting plate 5 and meshes with the internal gear ring 9. The limiting block 12 has a T-shaped structure and is fixedly installed on the inner wall of the through groove opened at the bottom of the mounting ring 6. The rack 10 is movably inserted into the through groove at the bottom of the mounting ring 6. Inside, the rack 10 has a through slot for the insertion of the limiting block 12. The rack 10 meshes with the gear 8. One end of the rack 10 is fixedly connected to a connecting frame 11. The top wall of the connecting frame 11 is located above the mounting plate 5. The rotating component includes a U-shaped placement frame 13 and a first motor 14. The top of the placement frame 13 is fixedly connected to the bottom of the mounting ring 6. The first motor 14 is fixedly installed inside the placement frame 13. The output end of the first motor 14 is fixedly connected to one of the gears 8. The first motor 14 drives one of the gears 8 to rotate. Under the action of the gear 8, the gear 8 drives the inner gear ring 9 to rotate. Then, the inner gear ring 9 drives multiple gears 8 to rotate. Since the gear 8 meshes with the rack 10, when the gear 8 rotates, the rack 10 drives the connecting frame 11 to move, so that multiple connecting frames 11 move closer to each other.

[0027] The ends of the multiple connecting frames 11 in the upper clamping device are respectively fixedly connected to the multiple mounting frames 2, and the ends of the multiple connecting frames 11 in the lower clamping device are respectively fixedly connected to the multiple clamping blocks 4.

[0028] The driving device includes a rotating rod 16, a guide rod 17, and two support frames 15. Both support frames 15 are fixedly connected to the top of the base 1. The rotating rod 16 is movably connected to one support frame 15, and the guide rod 17 is fixedly connected to the other support frame 15. The rotating rod 16 is threadedly connected to the connecting block 7 on one side of the mounting ring 6, and the guide rod 17 is movably connected to the connecting block 7 on the other side of the mounting ring 6. A second motor 18 is provided at the top of the rotating rod 16. The second motor 18 is mounted on the top of the support frame 15, and the output end of the second motor 18 is fixedly connected to the end of the rotating rod 16. The second motor 18 drives the rotating rod 16 to rotate, thereby causing the two clamping devices to move.

[0029] The working principle of this utility model is as follows: When using the device, the pipe is inserted into the central circular hole of the mounting plate 5, and the first motor 14 in the upper clamping device is started. The first motor 14 drives one of the gears 8 to rotate. Under the action of the gear 8, the gear 8 drives the internal gear ring 9 to rotate, and then the internal gear ring 9 drives multiple gears 8 to rotate. Since the gear 8 meshes with the rack 10, when the gear 8 rotates, the rack 10 drives the connecting frame 11 to move, so that multiple rollers 3 come closer to each other and contact the outer surface of the pipe. During the process of the pipe being lowered by the traction chain, the rollers 3 rotate. When the pipe is near the top and located at multiple rollers 3, the multiple rollers 3 are separated from each other and clamped to the outer wall of the pipe by multiple clamping blocks 4 on the lower clamping device. At this time, the second motor 18 drives the rotating rod 16 to rotate, so that the two clamping devices move down and the pipe gradually moves down, thus facilitating the installation of the pipe.
