Abstract

The application relates to the technical field of pile foundation concrete construction, and discloses a pile foundation concrete pouring enclosure device which comprises a circular plate, a ball screw, a screw nut, a cylinder, guide rails, sliding blocks, movable plates, enclosure plates and connecting rods. During use, the ball screw is driven to rotate, and the screw nut drives the cylinder to move; then, under the pulling or pushing of the connecting rods and the guiding and supporting of the guide rails and the sliding blocks, the movable plates move along the radial direction of the circular plate, and finally the enclosure plates are driven to move close to or away from each other.

Therefore, only a relatively large-diameter enclosure plate needs to be used, the maximum enclosure range of the device can be improved, the minimum maintenance range is not affected, and different sizes of pile foundations can be maintained.

Description

Technical Field

[0001] This application relates to the field of pile foundation concrete construction technology, and for example to a pile foundation concrete pouring retaining device. Background Technology

[0002] A related technology (publication number: CN220202775U) discloses a concrete pouring retaining device for pile foundation construction, comprising multiple retaining plates that can be inserted around the pile foundation to form a cylindrical structure. Each retaining plate has a steel pipe fixedly embedded in its outer wall, and locking components are mounted on the multiple steel pipes. The locking components include a central connecting rod. Multiple annularly distributed sleeves, all perpendicular to the central connecting rod, are fixedly installed on the wall of the central connecting rod. Each sleeve has a sliding rod with a sliding connection. An open ring is fixedly installed on each sliding rod, and the open ring is fitted onto the steel pipe and fixedly connected to the steel pipe by locking screws inserted on both sides of the open ring. An adjusting component for adjusting the distance between the open ring and the central connecting rod is provided on the central connecting rod. The adjusting component includes a threaded rod. The threaded rod is fixedly installed on the central connecting rod and coaxially arranged with the central connecting rod. A threaded sleeve with a threaded connection is fitted on the threaded rod, and a rotating ring with a rotating connection is fitted on the threaded sleeve. Multiple rotating connecting plates are installed on the rotating ring.

[0003] In implementing the above embodiments, at least the following problems were found in the related technology:

[0004] During use, the rotating threaded sleeve causes it to slide up or down along the threaded rod. The connecting plate then pulls or pushes the sliding rod along the inside or outside of the sleeve. Therefore, the inner diameter of the pile foundation enclosure can be adjusted according to actual needs; simply replacing the enclosure plate with one of the appropriate size is sufficient. However, when a larger inner diameter of the pile foundation enclosure is required, a longer sleeve is necessary. This sleeve length limitation results in a larger minimum inner diameter for the pile foundation enclosure, making it inconvenient for enclosures of different pile foundation sizes.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0017] The pile foundation concrete pouring retaining device provided in this disclosure can achieve the following technical effects:

[0018] This disclosure provides a pile foundation concrete pouring retaining device, comprising a circular plate, a ball screw, a screw nut, a cylinder, guide rails, sliders, a movable plate, a retaining plate, and connecting rods. The circular plate includes multiple strip-shaped holes evenly distributed around its center, each extending towards the center of the plate and used for the passage of the connecting rods. The ball screw is rotatably mounted at the center of the circular plate, enabling it to rotate relative to the plate. The screw nut is mounted on the ball screw, and together they convert the rotational motion into linear motion. The cylinder is mounted on the screw nut and is aligned with the ball screw's centerline, moving along the axial direction of the ball screw under the influence of the screw nut. Guide rails are evenly installed around the center of the circular plate along its radial direction, adjacent to the multiple strip-shaped holes, and used to support the sliding sliders. The sliders are mounted on each guide rail, and together they provide guidance and support. Each movable plate is connected to a slider and can move radially along the corresponding circular plate under the guidance and support of the slider's guide rail. A retaining plate is detachably connected to each movable plate for maintaining the pile foundation. Connecting rods are rotatably mounted between each movable plate and the outer wall of the cylinder to transmit driving force. Multiple connecting rods are movably inserted through multiple slotted holes to avoid interference with the circular plate during movement.

[0019] During operation, the drive ball screw rotates, and the screw, via a nut, moves the cylinder axially along the ball screw. Then, under the pull or push of multiple connecting rods, and guided and supported by multiple guide rails and sliders, multiple movable plates move radially along the circular plate, ultimately causing the multiple retaining plates to move closer together or separate. Therefore, the inner diameter of the pile foundation's retaining structure can be adjusted according to actual needs; simply replace the retaining plates with those of the appropriate size. Furthermore, the guide rail and slider design ensures that the range of motion of any retaining plate approximates the radius of the circular plate. Therefore, using retaining plates with a larger diameter can increase the maximum retaining range of the device without affecting the minimum maintenance range. This facilitates maintenance of pile foundations of different sizes.

Among them, the ball screw 2 can be rotated in a controlled manner to make the multiple movable plates 7 move closer together or separate.

[0038] This disclosure provides a pile foundation concrete pouring retaining device, comprising a circular plate 1, a ball screw 2, a screw nut 3, a cylinder 4, a guide rail 5, a slider 6, a movable plate 7, a retaining plate 8, and a connecting rod 9. The circular plate 1 includes multiple strip-shaped holes evenly distributed around its center, all extending towards the center of the circular plate 1, and used for the passage of the connecting rod 9. The ball screw 2 is rotatably mounted at the center of the circular plate 1, enabling it to rotate relative to the circular plate 1. The screw nut 3 is mounted on the ball screw 2, and together they convert the rotational motion into linear motion. The cylinder 4 is mounted on the screw nut 3 and is arranged along the same centerline as the ball screw 2, moving along the axial direction of the ball screw 2 under the drive of the screw nut 3. The guide rail 5 is evenly mounted around the center of the circular plate 1 along its radial direction, and is adjacent to the multiple strip-shaped holes, used to support the sliding slider 6.

Multiple connecting rods 9 are movably inserted through multiple slotted holes to avoid interference with the circular plate 1 during movement.

[0039] During operation, the ball screw 2 rotates, and the nut 3 drives the cylinder 4 to move axially along the ball screw 2. Then, under the pulling or pushing of multiple connecting rods 9, and with the guiding and supporting action of multiple guide rails 5 and multiple sliders 6, multiple movable plates 7 move radially along the circular plate 1, ultimately causing multiple retaining plates 8 to move closer together or separate. Therefore, the inner diameter of the pile foundation's enclosure can be adjusted according to actual needs; simply replace the retaining plate 8 with one of the appropriate size. Furthermore, the design of the guide rails 5 and sliders 6 ensures that the range of motion of any retaining plate 8 is approximately the radius of the circular plate 1. Therefore, using retaining plates with a larger diameter can increase the maximum enclosure range of the device without affecting the minimum maintenance range.
