Description

Technical Field

[0001] This utility model relates to the field of sheet pile guidance control technology, specifically a straightness control device for U-shaped sheet pile construction. Background Technology

[0002] In basic pile driving engineering construction, sheet pile driving is widely used in engineering fields such as support structures, dam reinforcement and underground continuous walls.

[0003] Traditional pile driving methods often employ single hoisting and manual positioning, resulting in low construction efficiency, difficulty in controlling verticality, and challenges in aligning adjacent sheet piles. Furthermore, existing equipment lacks effective guiding and limiting structures during continuous pile driving and relies on manual experience for posture adjustments. This makes it difficult to achieve precise vertical sinking and tight alignment of sheet piles, leading to deviations, tilting, or misalignment, which negatively impacts overall construction quality.

[0004] Therefore, there is an urgent need for a straightness control device for U-shaped sheet pile construction with automatic guidance and flexible adjustment functions to improve the efficiency and quality of sheet pile construction. Utility Model Content

[0006] The technical solution is as follows: A straightness control device for U-shaped sheet pile construction includes a connecting seat and a guide frame. The connecting seat is connected to a U-shaped guide frame on one side. It also includes a positioning adjustment component and a follow-up limiting component. The guide frame is symmetrically equipped with positioning adjustment components for sheet pile straightness control. The positioning adjustment component includes a positioning seat, a guide roller, an electric push rod, and a top block. The guide frame is symmetrically equipped with positioning seats on one side, and a guide roller for adjusting the verticality of the sheet pile side is rotatably mounted on the positioning seat. The other side of the guide frame is symmetrically equipped with electric push rods, and an electric push rod is also equipped on the guide frame near the guide roller. The telescopic shaft ends of the electric push rods are respectively connected to the top blocks. The guide frame is also equipped with follow-up limiting components for assisting in adjusting the position of the sheet pile.

[0007] Furthermore, the follower limiting component includes a connecting shaft, a connecting arm, a limiting wheel, a torsion spring, and a limiting block.

The guide frame is also provided with a limiting block for blocking the connecting arm.

[0008] Furthermore, it also includes a guide component mounted on the guide frame. The guide component includes a guide block and a positioning wheel. The guide blocks are symmetrically arranged at the front and back of the U-shaped opening of the guide frame. The positioning wheel for guiding and adjusting the side of the sheet pile is rotatably connected to the guide block.

[0009] Furthermore, the guide block has an inclined opening on its inner side, and the two inclined openings form an open structure.

[0010] Furthermore, it also includes a guide member, which is disposed at the U-shaped opening of the guide frame. The guide member includes a limiting plate, a guide wheel, and a guide plate.

[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0020] Detailed Implementation: This utility model provides a straightness control device for U-shaped sheet pile construction, combined with... Figures 1 to 5 The system includes a connecting seat 1, a guide frame 2, a positioning adjustment component, and a follow-up limiting component. The guide frame 2 is connected to one side of the connecting seat 1. The guide frame 2 has a U-shaped structure design, which can push the sheet piles a to make adjacent sheet piles a close together. The positioning adjustment component is symmetrically arranged on the guide frame 2. The positioning adjustment component includes a positioning adjustment seat 3, a guide roller 30, an electric push rod 4, and a top block 40. The positioning seat 3 is symmetrically arranged vertically on one side of the guide frame 2. The guide roller 30 is rotatably arranged on the positioning seat 3 for adjusting the verticality of the side of the sheet pile a. The electric push rod 4 is symmetrically arranged front and back on the other side of the guide frame 2. The electric push rod 4 is also arranged on the guide frame 2 near the guide roller 30. The telescopic shaft end of the electric push rod 4 is connected to the top block 40. The straightness of the sheet pile a can be flexibly controlled and adjusted through the positioning adjustment component. The guide frame 2 is also equipped with a follow-up limiting component.

[0021] Furthermore, in combination Figures 1 to 5 The follow-up limiting component includes a connecting shaft 5, a connecting arm 50, a limiting wheel 51, a torsion spring 52, and a limiting block 53. The connecting shaft 5 is symmetrically distributed on the guide frame 2 on the side opposite to the guide roller 30. The connecting arm 50 is movably sleeved on the connecting shaft 5. The end of the connecting arm 50 is rotatably connected to the limiting wheel 51, and the torsion spring 52 is connected between the outer end of the connecting shaft 5 and the connecting arm 50. The guide frame 2 is also provided with a limiting block 53 for blocking the connecting arm 50. The follow-up limiting component can effectively assist in adjusting the position of the sheet pile a during the sinking process, which is conducive to accurately controlling the straightness of the sheet pile a installation.

[0022] Furthermore, in combination Figures 1 to 5It also includes guide components set on the guide frame 2. The guide components include guide blocks 6 and positioning wheels 61. Guide blocks 6 are symmetrically arranged at the front and back of the U-shaped opening of the guide frame 2. Positioning wheels 61 are rotatably connected to the guide blocks 6 to assist in the vertical guidance and adjustment of the side of the sheet pile a, so as to avoid the situation of tilting during sinking. The guide blocks 6 have inclined openings 60 on the inner side, and the two inclined openings 60 form an open structure, which is conducive to the close distribution of adjacent sheet piles a, thereby achieving the purpose of neat arrangement.

[0023] Furthermore, in combination Figure 1 , Figure 2 , Figure 4 and Figure 5 It also includes a guide component, which is set at the U-shaped opening of the guide frame 2. The guide component includes a limiting plate 7, a guide wheel 70, and a guide plate 71. The U-shaped opening of the guide frame 2 is also symmetrically provided with limiting plates 7 at the front and back. The guide wheel 70 is rotatably arranged inside the limiting plate 7. The side of the limiting plate 7 is also connected to the guide plate 71, and the two guide plates 71 also form an open structure, which can play an auxiliary guiding role for the sinking sheet piles a, so that each sheet pile a can be installed side by side and neatly connected to form a row of tight protective support structure.

[0024] In addition, combined Figure 1 and Figure 2 It also includes an electronic level 8. The electronic level 8 is installed on the front top of the guide frame 2, and the electric push rod 4 is electrically connected to the electronic level 8 through the controller to control and adjust the state of the sheet pile a in real time so that the sheet pile a can remain vertical and sink.

[0025] The connecting seat 1 is installed on the end of the extrusion arm of the pile driver. The U-shaped sheet pile a is moved to the designated position by hoisting. Then, the sheet pile a is slowly lowered so that its lower end naturally abuts the ground, and the hoisting rope is wound up to keep the sheet pile a relatively vertical. When the extrusion arm of the pile driver and the connecting seat 1 descend to the upper end of the sheet pile a, the directional guidance of the limiting wheel 51 and the guide roller 30 can play a circumferential limiting and guiding role on the upper end of the sheet pile a, which is conducive to flexibly adjusting the sinking state of the sheet pile a. At this time, the hoisting rope can be released, and by controlling the extrusion arm of the pile driver to continue to slowly press down, the sheet pile a can be inserted into the designated area. Meanwhile, during the continuous sinking of sheet pile a, in order to maintain the vertical insertion of sheet pile a, the electronic level 8 and the electric push rod 4 are used in conjunction to control the extension and retraction of the electric push rod 4 on the left and front and rear sides. This allows for real-time control and adjustment of the state of sheet pile a during its sinking process, ensuring that sheet pile a remains vertical and sinks to the specified depth. Similarly, when other sheet piles a need to be sinked in series to the specified depth, the other sheet piles a are hoisted to the position relative to the sinking sheet pile a, with the lower end of the sheet pile a contacting the ground and the hoisting rope in position. Under hoisting stress, the guide frame 2 is first controlled to move downwards along the sheet pile a and then rise. When the guide frame 2 moves downwards to be flush with the upper end of another sheet pile a, it is controlled to move to the right side. Under the pushing action of the guide roller 30, the side contact surfaces of the two sheet piles a are made to fit tightly and align. With the auxiliary guiding action of the guide plate 71, guide wheel 70, and the inclined opening 60 on the guide block 6, the two sheet piles a are kept horizontally aligned. During this process, when the limiting wheel 51 in the normal state contacts the side of the fixed sheet pile a and continues to move to the right, it can push the limiting wheel 51 to the left. The thrust is applied to allow the limiting wheel 51 to rotate and unfold to the left, and in conjunction with the torsion spring 52, the limiting wheel 51 is pressed tightly against the side of another sheet pile a, thereby providing vertical guidance for the sheet pile a. Subsequently, the levelness can be automatically detected by the electronic level 8 and, in conjunction with the electric push rod 4, the state of the sheet pile a can be flexibly controlled and adjusted to keep the sheet pile a vertical and aligned with the other sheet pile a. Then, the extrusion arm of the pile driver can be controlled to move down to extrude and sink the sheet pile a to the specified depth. In this way, by repeating the above operations, continuous and precise vertical extrusion of the sheet pile a can be achieved.

[0026] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
