Description

Technical Field

[0001] This invention relates to the field of auxiliary structures for pipe pile construction, and more specifically, to a positioning device for pipe pile construction. Background Technology

[0002] In the construction of bridges or high-rise buildings, a large number of pipe piles are required as the foundation structure, and the distribution of these piles must meet certain requirements to achieve the necessary support effect. Therefore, before driving the pipe piles, it is necessary to mark the corresponding positions in advance. Currently, two common methods are used: one is to mark by sprinkling lime, and the other is to place rings as markers. Both methods are relatively simple and convenient to use; however, they also have significant drawbacks. The former is easily washed away by rain, and the markers disappear. The latter is only a simple ring structure with poor overall structural strength, and may be deformed or even damaged by the pipe piles during construction, affecting subsequent use. Furthermore, both methods require external equipment and instruments and relatively complex steps for alignment and positioning, making them inconvenient to use and requiring improvement.

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 , Figure 3 As shown in the figure, a positioning device for pipe pile construction is disclosed in a specific embodiment of the present invention, including two support frames 100, two splicing parts 200, multiple insertion rods 300, and an external connecting rod 400; the support frames 100 are semi-circular structures, the two support frames 100 are arranged opposite each other and connected by splicing parts 200 to form a closed-loop structure; the support frames 100 are provided with multiple insertion holes 110, and the support frames 100 are fixed to the ground by insertion rods 300 passing through the insertion holes 110; at least one alignment structure 500 is provided on one support frame 100, the alignment structure moves along the support frame in an arc trajectory, the alignment structure 500 is locked by a locking mechanism 600, the alignment structure 500 is provided with a prism 510, and one end of the external connecting rod 400 is sleeved on the prism 510 to guide the alignment direction.

[0033] A novel positioning device for pipe pile construction includes two support frames, two splicing components, multiple insertion rods, and an external connecting rod. The support frames are semi-circular, with the two frames facing each other and connected by the splicing components to form a closed-loop structure. Multiple insertion holes are provided on the support frames, which are then fixed to the ground by insertion rods passing through these holes. The device employs an assembly-type structure, facilitating disassembly and replacement. Even if partial structural damage occurs, targeted replacement can be performed, reducing operating costs. Furthermore, for non-fully embedded pipe pile construction, it can be disassembled and directly extracted without needing to be removed from the top of the pipe pile, simplifying construction.

[0034] A support frame is provided with at least one alignment structure. The alignment structure moves along an arc-shaped trajectory along the support frame. The alignment structure is locked by a locking mechanism. The alignment structure is provided with a prism, and one end of an external rod is sleeved on the prism to guide the alignment direction; for example... Figure 2 As shown, according to the actual layout requirements, a corresponding number of alignment structures can be selected and installed. The alignment foundation is achieved by adjusting the position of the alignment structures. The structures are distributed outward from the center to achieve the required layout distribution effect of the points, which facilitates the marking of the points during construction. The external rods are used to extend outward, which makes it easier to indicate and align. It is also easy to cooperate with another positioning device to achieve the connection between the two and enhance the overall coordination.

[0035] Furthermore, the external rods are fitted onto the prism. Due to the specific structure of the prism, the external rods cannot rotate, thus achieving effective alignment. It should be noted that the centers of the prism and the support frame are in the same vertical plane, ensuring that the center of the support frame and the external rods are in the same direction, thus ensuring the accuracy of the indicated direction.

[0036] Furthermore, the docking rod 400 includes a tube 410, with collars 420 installed at both ends of the tube 410. The shape of the collars 420 is adapted to the shape of the prism 510. The collars can be fitted onto the prism to realize the installation of the docking rod, and its direction is fixed, thus realizing the guidance of the required angle. The inner walls of the two ends of the tube are provided with internal threads, and the collars are fixed with inserts. The diameter of the inserts is adapted to the inner diameter of the tube, and the outer wall of the inserts is provided with external threads. The inserts and the tube are threadedly connected and matched. The assembly structure is convenient for production and assembly. Moreover, according to actual needs, external rods of different lengths can be selected to achieve the alignment effect of fixed length and orientation. Positioning can be achieved by guiding multiple rods with one rod, which facilitates the layout planning of the overall positioning device.

[0037] Furthermore, such as Figure 3 , Figure 4 As shown, the support frame 100 includes a semi-annular base 120, with an insertion hole 110 on the base 120. A protruding strip 130 is fixedly provided on the top surface of the inner ring of the base 120, extending along the inner ring of the support frame. The design of the protruding strip strengthens the structural strength of the inner ring of the support frame. This part is the first contact point that may collide with the pipe pile. The protruding strip enhances the anti-collision and anti-deformation effect. A first guide strip 140 is fixedly provided on the outer top of the protruding strip 130, and a second guide strip 150 is fixedly provided on the top of the outer ring of the base 120. The end of the first guide strip 140 is provided with a first screw. The end of the second guide strip 150 is provided with a second threaded hole 151. The splice 200 is slidably disposed at the first guide strip 140 and the second guide strip 150. When the splice 200 slides to the end of the first guide strip 140 and the second guide strip 150, the two support frames are connected by locking knobs. The movement of the splice is effectively limited by the two sliding locking parts to ensure that it will not easily loosen and to provide a stable locking. And the effective connection is achieved by locking knobs at multiple points, so that the splice forms a stable connection between the two support frames.

[0038] Furthermore, the base includes a first semi-ring plate and a second semi-ring plate. The inner diameter of the second semi-ring plate is larger than the outer diameter of the first semi-ring plate. The first and second semi-ring plates are fixedly connected by multiple frame strips. A protruding strip is provided on the top surface of the first semi-ring plate, and a second guide strip is provided on the outer edge of the second semi-ring plate. Insertion holes are provided on the frame strips and the second semi-ring plate, and the insertion holes on the frame strips and the insertion holes on the second semi-ring plate are staggered to further disperse the hole positions, making it convenient to insert the insertion rod according to actual needs, thereby providing a stable grounding connection. It can also reduce the overall weight and facilitate handling and use.

[0039] Furthermore, a diagonal brace is fixed between the frame bar and the outer wall of the convex bar. The diagonal brace supports and strengthens the convex bar, thereby further enhancing the structural strength of the entire support frame and preventing deformation of the convex bar.

[0040] Furthermore, the insertion rod includes a rod strip whose diameter matches the diameter of the insertion hole. The bottom end of the rod strip has a pointed structure, and a pressure plate is fixedly provided at the top end of the rod strip. A lifting ring is fixedly provided on the top surface of the pressure plate. The insertion rod penetrates the insertion hole and extends into the ground. The pressure plate presses against the base support, making the base support close to the ground. The lifting ring facilitates the subsequent removal of the insertion rod and makes disassembly convenient.

[0041] Furthermore, such as Figure 5 As shown, the splicing component 200 includes a first frame plate 230. A first slide block 210 and a second slide block 220 are fixedly mounted at both ends of the first frame plate 230. The first slide block 210 is slidably mounted on a first guide strip 140, and the second slide block 220 is slidably mounted on a second guide strip 150. Two first locking knobs 240 are installed on the first slide block 210, corresponding to first threaded holes. Two second locking knobs 250 are installed on the second slide block 220, corresponding to second threaded holes. These measures limit the movement of the splicing component along the first and second guide strips. When the two support frames are aligned, the splicing component can smoothly move to the alignment point, facilitating the connection of the two support frames. The two first locking knobs and two second locking knobs can connect the ends of the two support frames, thus achieving the connection of the two support frames. The use of locking knobs for locking facilitates disassembly and use, and effectively prevents easy loosening.

[0042] Furthermore, a handle is fixedly provided on the top surface of the first frame board, which can be easily lifted and pushed to adjust the position of the splicing parts, and also to facilitate the gripping part of the subsequent support frame, making it easy to move the entire support frame.

[0043] Furthermore, the inner wall of the protrusion is inclined and tilted downwards in the axial direction. This structural design enables the inner side of the protrusion to form a downwardly narrowing guide surface. When the insertion end of the pipe pile contacts the guide surface, it can move downwards, reducing the impact and preventing damage to the protrusion.

[0044] Furthermore, such as Figures 6 to 8 As shown, the alignment structure 500 includes a sliding frame 520, a gear 530, and a locking mechanism 600; a prism 510 is fixedly mounted on the sliding frame 520; the gear 530 is rotatably mounted on the sliding frame 520, and the locking mechanism 600 is mounted on the sliding frame 520 and can lock the gear 530; a rack 142 is provided on the outer side of the first guide strip 140, and the rack extends along the first guide strip; the sliding frame 520 is slidably mounted on the first guide strip 140 and the second guide strip 150, and the gear 530 meshes with the rack 142 for transmission; by using the meshing transmission of the gear and rack, when the gear is locked, the entire sliding frame can be effectively locked, thereby enabling more angle adjustments.

[0045] Furthermore, the sliding frame 520 includes a second frame plate 521. A third slide block 522 is fixedly provided at one end of the second frame plate 521, and a fourth slide block 523 is fixedly provided at the other end. The third slide block 522 is slidably disposed on the first guide strip 140, and the fourth slide block 523 is slidably disposed at the second guide strip 150. The limiting at both ends can effectively guide the sliding frame and prevent the sliding frame from shifting, facilitating subsequent alignment adjustments. A clamping groove 524 is provided at the third slide block 522. The side of the clamping groove near the rack is open, and the rack 142 extends into the clamping groove 524. The gear 530 is rotatably mounted in the clamping groove 524 via the support shaft 540; the top end of the support shaft 540 passes through the top of the clamping groove and protrudes from the top surface of the third slide 522, providing a mounting position for the gear and maintaining the transmission engagement with the rack; the locking mechanism 600 is mounted on the top surface of the third slide 522, and the locking mechanism 600 locks the support shaft 540; the prism 510 is fixedly mounted on the top surface of the fourth slide 523, and the prism is located near the edge of the support frame, which can prevent positional interference with other structural components and facilitate the subsequent placement of external rods.

[0046] Furthermore, a protruding post 541 is fixedly provided on the top surface of the support shaft 540. The protruding post has a prismatic prism structure. The locking mechanism 600 includes a support frame 610 and a universal sleeve 620. The support frame 610 is fixed to the top surface of the third slide block 522 by bolts. The support frame 610 is provided with a bayonet 611, which has a prismatic hole structure. The outer wall of the universal sleeve has a prismatic structure. The shape of the outer wall of the universal sleeve 620 is adapted to the shape of the bayonet 611. The universal sleeve 620 passes through the bayonet 611 to ensure that the universal sleeve can only move vertically and will not rotate. Therefore, it will not rotate with the gear. Conversely, it means that the gear can be locked. The universal sleeve can be adjusted to move down to fit on the protruding post and lock the support shaft. The universal sleeve can also be adjusted to move up to disengage from the protruding post and release the lock. The universal sleeve is a tool used to clamp the prismatic structure. It can be purchased and used on the market. The specific structure is not described in detail.

[0047] Furthermore, a gripper 630 is installed on the top of the universal sleeve 620; a limiting ring 621 is fixedly provided on the outer bottom of the universal sleeve 620, and multiple first magnet blocks 622 are embedded on the top surface of the limiting ring 621; multiple second magnet blocks 640 are correspondingly provided on the outer bottom end of the bayonet 611. The universal sleeve can be adjusted to move upward until the first magnet blocks and second magnet blocks are magnetically connected, so that the universal sleeve is detached from the protrusion and maintains the unlocked state; the universal sleeve can be adjusted to move downward until the gripper abuts against the top surface of the third slide, and the universal sleeve is sleeved on the protrusion and the support shaft is locked; the upward movement of the universal sleeve is limited by the limiting ring to ensure that the universal sleeve cannot be detached from the bayonet, and the magnetic attraction of the first and second magnet blocks keeps the universal sleeve detached from the protrusion; the gripper allows for easy lifting and placing of the universal sleeve, facilitating adjustment and use.

[0048] Furthermore, the gripper includes a circular plate, which is fixed to the universal sleeve by bolts. The diameter of the circular plate is larger than the maximum opening span of the bayonet. A ball head is fixed on the top surface of the circular plate. When assembling the locking mechanism, the gear needs to be placed in the clamping groove first, then the support shaft is inserted and connected by the insert. Next, the universal sleeve is magnetically attached to the support frame, and then the support frame is installed on the top surface of the third slide. Finally, the gripper is installed on the universal sleeve to complete the assembly of the locking mechanism.

[0049] Furthermore, the top surface of the first guide strip is provided with scale lines for indicating the angle; the top surface of the third slide is provided with an arrow-shaped pointer, which makes it easier to adjust the angle and facilitates operation.

[0050] This invention has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. This invention is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims are also within the protection scope of this invention.
