Description

Technical Field

[0001] This utility model relates to the field of foundation pipe pile technology, and specifically to a docking and positioning device for hollow concrete pipe piles. Background Technology

[0002] With the in-depth development of foundation engineering technology, a variety of foundation construction methods have emerged, among which pipe pile foundation is one of the most commonly used foundation forms. A pipe pile foundation involves welding multiple sections of pipe piles together to form a complete pile body, which is then connected to the pile cap to create a structurally sound foundation. Before welding, it is crucial to ensure that the upper and lower sections of the pipe piles are not significantly misaligned. For vertical pipe piles, to guarantee the overall support strength, the verticality of the upper section must also be ensured during the welding process. When welding two sections of pipe piles, a pile driver is used to lift one section of the pile and suspend it in the air. The relative positions of the upper and lower sections are repeatedly adjusted manually by pushing or pulling before the pile is lowered for welding. After the pile is lowered, two people must use crowbars to adjust the position of the pipe pile, and even after alignment, the verticality of the upper section must still be adjusted in conjunction with the pile driver. Therefore, the current pipe pile welding process is extremely complex and inefficient. Utility Model Content

[0017] The following is a description of the embodiments and appendices. Figures 1-3The technical solution of this utility model will be further described below.

[0018] Example 1

[0019] A concrete hollow pipe pile docking and positioning device includes: a lower positioning mechanism 1 and an upper positioning mechanism 2. Both the lower positioning mechanism 1 and the upper positioning mechanism 2 include a positioning ring 31 and a limiting module 32. The positioning ring 31 includes an arc-shaped plate 311 and an arc-shaped plate 312 that are hinged to each other. The limiting module 32 includes a bolt rod 321, a limiting block 322, and a rotating part 323. The middle part of the bolt rod 321 is threadedly connected to the positioning ring 31, and the rotating part 323 is fixedly provided at its tail end. The limiting block 322 is rotatably provided at the front end of the bolt rod 321 through a rotating base. A guide groove 41 is provided through the middle of the arc-shaped plate 311 and the arc-shaped plate 312. A support rod 42 is slidably provided in the guide groove 41, and a limiting nut 421 is rotatably provided on the support rod 42.

[0020] like Figures 1-3 As shown, the operating procedure for the connection of hollow concrete pipe piles according to this utility model is as follows:

[0021] S1: First, place the lower positioning mechanism 1 on the lower pipe pile. By rotating the rotating part 323 of the limiting module 32, the bolt rod 321 is rotated, so that the limiting block 322 is tightly abutted against the outer wall of the lower pipe pile, thereby achieving a stable fixation of the lower positioning mechanism 1.

[0022] S2: Next, slide the support rod 42 to a suitable position so that it is positioned in the guide groove 41. Then rotate the limit nut 421 to firmly fix the support rod 42 on the lower positioning mechanism 1 to ensure its stability.

[0023] S3: Install the upper positioning mechanism 2 at the end of the hollow concrete pipe pile to be connected. At this time, the support rod 42 slides into the guide groove 41 of the upper positioning mechanism 2, which serves as a guide.

[0024] S4: By adjusting the limiting module 32 of the upper positioning mechanism 2, i.e., rotating the rotating part 323, the bolt rod 321 is moved, which in turn drives the limiting block 322 to move, thereby achieving fine adjustment of the upper pipe pile. Ultimately, precise alignment of the upper and lower pipe piles is achieved.

[0025] The limiting module 32 of this utility model can be adjusted according to usage requirements to adapt to pipe piles of different sizes, improving versatility and flexibility. During installation, it is guided by the support rod 42, saving time and effort. Combined with the limiting nut to fix the support rod, it ensures stability during the connection process. The overall design simplifies the process, reduces construction time and labor requirements, improves work efficiency, lowers construction costs, and ensures project progress.

[0026] As a further improvement, both the first arc plate 311 and the second arc plate 312 are provided with a locking mating surface 43 at the end away from the hinge. A locking hole 44 is provided through the locking mating surface 43, and a locking element can be inserted into the locking hole 44.

[0027] Specifically, a locking hole 44 is provided through the locking mating surface 43, into which a locking element, such as a pin or bolt, can be inserted. When the positioning ring 31 is closed, by inserting the locking element into the locking hole 44, the arc plate 311 and the arc plate 312 can be firmly locked, preventing them from accidentally opening during use, ensuring the stability of the positioning device, enhancing the reliability of the positioning device, and ensuring that the positioning ring 31 can remain stably closed during docking, thereby improving the accuracy and safety of docking.

[0028] In a further improvement, two sets of limiting modules 32 are provided on either the first arc plate 311 or the second arc plate 312, and the two sets of limiting modules 32 are symmetrically arranged on both sides of the guide groove 41.

[0029] As a further improvement, an L-shaped positioning rod 45 is slidably provided on the lower positioning mechanism 1.

[0030] During the docking operation, the L-shaped positioning rod 45 provides additional guidance to ensure that the hollow concrete pipe piles maintain the correct centering position during docking, reduce offset and error, effectively improve the success rate and efficiency of docking, and reduce the difficulty of construction.

[0031] As a further improvement, at least two limiting nuts 421 are provided on the support rod 42.

[0032] As a further preferred embodiment, four limiting nuts 421 are provided.

[0033] Specifically, the support rod 42 is limited by the limiting nut 421 to prevent the support rod 42 from slipping during use.

[0034] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
