Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, specifically to an automatic positioning device for pipe pile molds. Background Technology

[0002] Current construction work requires the extensive use of pipe piles. Pipe pile molds are used during production, and these molds can be reused multiple times. A pipe pile mold consists of an upper mold cover and a lower mold cover, which are fastened together with multiple studs. After each use, cement residue remains at the contact point between the two mold covers. If this cement residue is not cleaned up promptly, it will affect the reuse of the mold, thus impacting the production quality of subsequent batches of pipe piles, and may even pose a significant risk of safety accidents during subsequent construction.

[0003] Therefore, in the production of pipe piles, multiple different operations are performed using pipe pile molds: for example, tightening bolts on the pipe pile molds to facilitate subsequent centrifugal concrete assembly; transporting the centrifuged square piles with molds for curing; disassembling bolts on the pipe pile molds before demolding to facilitate demolding and transport of finished pipe piles; and cleaning the pipe pile molds afterward. Currently, many of these different operations are performed manually, leading to low efficiency, high labor costs, high production risks, and low automation levels. To improve automation, a batch of automated equipment needs to be developed to complete these different operations. However, in automated operations, the pipe pile molds during transport must be positioned first. Only by ensuring precise positioning can other tooling (such as bolt tightening devices, bolt disassembly devices, mold cleaning devices, etc.) perform subsequent precise automated operations on the pipe pile molds during transport. Furthermore, during this positioning process, it is essential to ensure that the pipe pile molds do not stop transporting, thereby truly achieving significantly improved work efficiency, significantly reduced labor costs, and significantly reduced production risks.

[0004] A prior art patent, CN218170853U, discloses a solution including a frame for mounting external operating equipment. Two vertically arranged horizontal positioning clamping frames are movably mounted on the frame to form a pipe pile mold transmission channel between them. Each horizontal positioning clamping frame has a positioning guide sleeve at its bottom. The frame also has a drive assembly connected to the two horizontal positioning clamping frames. During operation, the drive assembly drives the two horizontal positioning clamping frames to gradually approach each other, guiding and clamping the running wheels on the pipe pile mold into the two positioning guide sleeves to form a position, facilitating precise operation of the pipe pile mold by the external operating equipment. This invention has the advantages of simple and compact structure, ease of manufacture and maintenance, high level of automation, significantly improved work efficiency, significantly reduced labor costs, and automated positioning of the pipe pile mold.

[0005] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0006] First, existing pipe pile molds often have cement blocks and other debris on the outside, which can cause uneven heights at both ends during fixing, affecting the molding efficiency during the pipe pile pouring process.

[0007] Secondly, the pipe pile mold is prone to tilting at both ends during placement, or the mating surface between the upper and lower molds may be tilted, which affects the stability of the installation between the upper and lower molds.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides an automatic positioning device for pipe pile molds. This device solves the problems of uneven heights at both ends of pipe pile molds during fixing due to the presence of cement blocks and other debris on the outside, which affects the forming efficiency during pipe pile casting. It also addresses the issues of molds being prone to tilting at both ends during placement, or the inclination of the mating surfaces between the upper and lower molds, which affects the stability of the installation between the upper and lower molds.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An automatic positioning device for pipe pile molds includes a support platform. Two sets of positioning structures are arranged in parallel along the longitudinal direction on the support platform. Each set of positioning structures includes a transverse adjustment seat that slides horizontally in the transverse direction. A height adjustment box is vertically raised and lowered on the transverse adjustment seat. Two support seats that move in opposite directions are slidably arranged at the upper end of the height adjustment box in the transverse direction. Reversing rollers are rotatably arranged on the opposite side walls of the two support seats.

[0012] As an optimized solution, the support base has a positioning inclined surface on the opposite end face, and an installation groove is formed on the positioning inclined surface, and the reversing roller is rotatably installed in the installation groove.

[0013] As an optimized solution, a top drive motor for driving the reversing idler roller to rotate is fixed to the side wall of the support base.

[0014] As an optimized solution, the upper end of the height adjustment box is provided with a rectangular sliding hole along the horizontal direction, and the lower end of the support base is respectively fixed with a sliding plate that is slidably installed in the rectangular sliding hole.

[0015] As an optimized solution, an internal lead screw is horizontally rotatably installed inside the height adjustment box. The internal lead screw has two external thread sections with opposite directions of rotation, and the two slide plates are respectively threadedly connected to the two external thread sections.

[0016] As an optimized solution, two internal seats are fixedly connected in parallel inside the height adjustment box, and the two ends of the internal lead screw are respectively rotatably mounted on the two internal seats. An internal drive motor that drives the internal lead screw to rotate is fixedly connected to one of the internal seats.

[0017] As an optimized solution, side lead screws are vertically rotatably mounted on the opposite outer walls of the lateral adjustment seat, and side drive plates that are threadedly connected to the side lead screws are fixed on the opposite outer walls of the height adjustment box.

[0018] As an optimized solution, side seats are fixedly connected to the opposite side walls of the lateral adjustment seat, the lower end of the side screw is rotatably mounted on the side seat, and a side drive motor for driving the side screw to rotate is fixedly connected to the lower end of the side seat.

[0019] As an optimized solution, the support platform is rotatably mounted with a bottom lead screw, and the lower end of the lateral adjustment seat is fixedly connected with two bottom drive plates that are threadedly connected to the bottom lead screw.

[0020] As an optimized solution, two bottom seats are fixedly connected side by side to the upper surface of the support platform, and the two ends of the bottom screw are rotatably mounted on the two bottom seats, with a bottom drive motor for driving the bottom screw to rotate fixedly connected to one of the bottom seats.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The system features two sets of positioning structures on the support platform, each operating independently to allow for independent adjustment of the ends of the pipe pile mold. The adjustable spacing between the two support seats allows for support of pipe pile molds with different diameters. By rotating the reversing rollers on the support seats, the system can correct the misalignment of the pipe pile mold's mating surface by using the reversing rollers to drive the pipe pile mold to rotate slightly, thus ensuring stability during the mating process between the upper and lower molds.

[0023] The height adjustment box can be raised and lowered vertically, which can be used to correct the uneven height of the two ends of the pipe pile mold when the two ends are not at the same height due to cement lumps on the outside.

[0024] The lateral adjustment seat can slide laterally, which allows the pipe pile mold to be adjusted to a parallel state when the two ends of the pipe pile mold are tilted. This greatly improves the stability and work efficiency during the assembly of the upper and lower molds. Attached Figure Description

[0030] like Figure 1 and Figure 2 As shown, the automatic positioning device for pipe pile mold includes a support platform 1. Two sets of positioning structures are arranged in parallel along the longitudinal direction on the support platform 1. Each set of positioning structures includes a horizontal adjustment seat 2 that slides horizontally along the transverse direction. A height adjustment box 3 is raised and lowered vertically on the horizontal adjustment seat 2. Two support seats 4 that move in opposite directions are arranged horizontally at the upper end of the height adjustment box 3. Reversing rollers 5 are rotatably arranged on the opposite side walls of the two support seats 4.

[0031] The support base 4 has a positioning slope on its opposite end face, and an installation groove is opened on the positioning slope. The reversing roller 5 is rotatably installed in the installation groove.

[0032] A top drive motor 6, which drives the reversing roller 5 to rotate, is fixedly connected to the side wall of the support base 4.

[0033] The upper end of the height adjustment box 3 has a rectangular sliding hole 7 opened horizontally, and the lower end of the support base 4 is fixed with a sliding plate 8 that is slidably installed in the rectangular sliding hole 7.

[0034] An internal lead screw 9 is horizontally rotatably installed inside the height adjustment box 3. The internal lead screw 9 has two external thread sections with opposite directions of rotation. The two slide plates 8 are respectively threadedly connected to the two external thread sections.

[0035] Two internal seats 10 are fixedly connected in parallel inside the height adjustment box 3. The two ends of the internal lead screw 9 are respectively rotatably mounted on the two internal seats 10. An internal drive motor 11 that drives the internal lead screw 9 to rotate is fixedly connected to one of the internal seats 10.

[0036] A side screw 13 is vertically rotatably mounted on the opposite outer wall of the horizontal adjustment seat 2. A side drive plate 14 threadedly connected to the side screw 13 is fixed on the opposite outer wall of the height adjustment box 3. A limit plate is fixed to the upper end of the side screw 13.

[0037] Side seats 12 are fixedly connected to the opposite side walls of the transverse adjustment seat 2. The lower end of the side screw 13 is rotatably mounted on the side seat 12.
