Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a guide support for steel pipe piles. Background Technology

[0002] When the foundations of cross-sea or cross-river bridges are located in water, temporary cofferdams are often required to reduce the impact of water on construction. Interlocking steel pipe pile cofferdams have been widely used in bridge foundation engineering in recent years due to their advantages such as simple fabrication, short construction period, high overall rigidity, high recyclability, and strong adaptability to planar layout. During the construction of interlocking steel pipe piles, high requirements are placed on the verticality control and driving efficiency of the steel pipe piles, as their verticality directly affects the closure and water-stopping effect of the cofferdam.

[0003] In building construction, the installation and positioning of steel pipe piles is a crucial step. Existing guide supports for steel pipe piles are mostly fixed and cannot be adjusted according to the size of the piles. This leads to frequent support replacements when handling piles of different sizes, which is time-consuming and labor-intensive. Furthermore, fixed guide supports are inconvenient to transport and store, increasing construction costs and failing to meet production demands. Therefore, a new guide support for steel pipe piles is proposed to address these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a guide support for steel pipe piles, which boasts advantages such as high construction efficiency and strong practicality. It solves the problem that most existing steel pipe pile guide supports are fixed and cannot be adjusted according to the size of the steel pipe pile, leading to frequent support replacements when handling steel pipe piles of different sizes, which is time-consuming and labor-intensive. Furthermore, fixed guide supports are inconvenient to transport and store, increasing construction costs and failing to meet production needs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a guide support for steel pipe piles, comprising a transverse main frame and a longitudinal positioning frame detachably installed outside the transverse main frame, wherein the upper surface of the longitudinal positioning frame is provided with a plurality of guide mechanisms.

[0006] The guiding mechanism includes a mounting base slidably mounted on the upper surface of the longitudinal positioning frame, a reciprocating motor fixedly mounted inside the mounting base, a threaded sleeve fixedly connected to the output shaft of the reciprocating motor, a moving block slidably connected inside the mounting base, a threaded rod fixedly connected to the back of the moving block, a limiting wheel rotatably mounted inside the mounting base, and a guide wheel disposed outside the moving block.

[0007] Furthermore, there are four horizontal main frames and four vertical positioning frames, and the four horizontal main frames and four vertical positioning frames are detachably connected in sequence.

[0008] Furthermore, four uprights are fixedly connected to the top of the bottom horizontal main frame, and the four uprights are distributed in a rectangular shape between the four horizontal main frames.

[0009] Furthermore, the threaded rod is rotatably connected to the inside of the threaded sleeve, a U-shaped frame is fixedly installed on the left side of the moving block, and the guide wheel is rotatably connected to the inside of the U-shaped frame.

[0010] Furthermore, a guide rod is fixedly connected inside the mounting base, and the movable block is slidably connected to the outside of the guide rod.

[0011] Furthermore, a number of limiting frames and fixing frames are fixedly connected sequentially between two adjacent longitudinal positioning frames, and the limiting frames and fixing frames are distributed sequentially between the two longitudinal positioning frames.

[0012] Furthermore, a number of columns are sequentially fixedly connected to the upper surfaces of the top horizontal main frame and the longitudinal positioning frame, and a number of crossbars are sequentially fixedly connected between the columns.

[0013] Furthermore, a support assembly is provided between two adjacent longitudinal positioning frames. The support assembly includes a fixed plate fixedly connected to the outside of the top longitudinal positioning frame and a support leg fixedly connected between the fixed plate and the longitudinal positioning frame. There are two sets of fixed plates, and a connecting leg is fixedly connected between the two sets of fixed plates.

[0014] Compared with the prior art, the present invention provides a guide support for steel pipe piles, which has the following advantages:

[0015] 1. This guide bracket for steel pipe piles uses a controller to start a reciprocating motor to drive a threaded sleeve to rotate. This allows the threaded sleeve to move a moving block within the mounting base, which can be flexibly adjusted according to the size of the steel pipe pile. The cooperation of the guide wheel and the limit wheel ensures that the steel pipe pile moves stably along a predetermined trajectory during the guiding process, significantly improving the positioning accuracy and guiding stability of the steel pipe pile. It can adapt to steel pipe piles of different sizes, eliminating the need for frequent component replacements and greatly improving construction efficiency, thus achieving the advantage of high construction efficiency.

[0016] 2. This guide support for steel pipe piles, by setting limit frames and fixing frames sequentially distributed between two longitudinal positioning frames, forms a stable frame structure. This effectively prevents the longitudinal positioning frames from lateral deformation or displacement under stress, enhancing the overall structural stability. The setting of columns and crossbars further improves the load-bearing capacity of the structure. The combination of fixing plates and support legs forms a stable triangular support structure, which can effectively distribute the load borne by the longitudinal positioning frames, reduce deformation or damage caused by concentrated loads, and further enhance the rigidity of the entire support assembly, enabling it to better resist lateral and torsional forces, achieving the advantage of strong practicality.

[0027] The threaded rod 10 is rotatably connected to the inside of the threaded sleeve 8, and a U-shaped frame 11 is fixedly installed on the left side of the moving block 9. The guide wheel 12 is rotatably connected to the inside of the U-shaped frame 11. The reciprocating motor 7 is started by the controller to drive the threaded sleeve 8 to rotate, so that the threaded sleeve 8 drives the moving block 9 within the mounting seat 6 to be flexibly adjusted according to the size of the steel pipe pile. The cooperation of the guide wheel 12 and the limit wheel 13 ensures that the steel pipe pile moves stably along the predetermined trajectory during the guiding process, which significantly improves the positioning accuracy and guiding stability of the steel pipe pile. It can adapt to steel pipe piles of different sizes, eliminates the need for frequent replacement of parts, greatly improves construction efficiency, and achieves the advantage of high construction efficiency.

[0028] Specifically, a guide rod 14 is fixedly connected inside the mounting base 6, and a movable block 9 is slidably connected to the outside of the guide rod 14.

[0029] In this embodiment, a number of limiting frames 4 and fixing frames 5 are fixedly connected sequentially between two adjacent longitudinal positioning frames 2, and the limiting frames 4 and fixing frames 5 are distributed sequentially between the two longitudinal positioning frames 2.

[0030] Among them, a number of columns 15 are fixedly connected to the upper surfaces of the top horizontal main frame 1 and the longitudinal positioning frame 2, and a number of crossbars 16 are fixedly connected between the columns 15.

[0031] Example 2:

[0032] Please see Figs. 1-3Based on Embodiment 1, a support assembly is included between two adjacent longitudinal positioning frames 2.
