Description

Technical Field

[0001] This invention relates to the technical field of building construction, and in particular to an adjustable-height building pipe pile specifically for building construction. Background Technology

[0002] Building construction refers to the construction of buildings, roads, bridges, water conservancy and other structures. Building pipe piles are usually used in the construction process. During construction, pipe piles are driven into the foundation pit and poured to improve the stability of the foundation.

[0003] The existing pipe piles still have the following shortcomings in actual use:

[0004] The length of existing pipe piles is usually fixed and cannot be adjusted. In actual use on the construction site, there are often situations where the foundation pit depth is insufficient or too deep. In this case, the fixed length pipe piles cannot be well adapted to the foundation pit, which has certain limitations.

[0005] Some existing pipe piles with height adjustment function have a lot of drive or transmission equipment inside. Once the equipment inside the pipe pile is placed, it cannot be removed and will be poured along with the pipe pile as a whole, which makes the overall cost of the pipe pile higher and is not conducive to its widespread use.

[0006] Therefore, there is an urgent need to design an adjustable-height building pipe pile specifically for building construction to solve the above problems.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0008] The purpose of this invention is to solve the problems existing in the prior art, and to propose an adjustable height building pipe pile for building construction.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An adjustable-height construction pipe pile for building engineering includes a lower pipe pile, a central connecting column fixedly installed inside the lower pipe pile, a central connecting pipe installed inside the lower pipe pile via a sliding mechanism, and an upper pipe pile fixedly installed at the upper end of the central connecting pipe. Two adjusting screws are threadedly installed inside the central connecting column, and two fixing plates are fixedly installed inside the upper pipe pile. Each fixing plate is equipped with a limit mechanism between itself and the corresponding adjusting screw. A communication mechanism is installed between the two fixing plates and the central connecting column.

[0011] The lower pipe pile is externally fitted with a bottom ring, and multiple positioning mechanisms are installed on the bottom ring. A connecting rod is fixedly installed on the lower part of each of the two adjusting screws. A telescopic rotating rod is rotatably installed on each of the connecting rods, and a fixed gear is fixedly installed at the lower end of each of the two telescopic rotating rods. Two moving gears are installed inside the bottom ring through a linkage mechanism, and the two moving gears respectively cooperate with the two fixed gears. An installation mechanism is installed between the bottom ring and the upper pipe pile.

[0012] In the above-mentioned adjustable height building pipe pile for construction engineering, the sliding mechanism includes an annular placement groove opened in the lower pipe pile, a plurality of trapezoidal limiting strips are fixedly installed in the annular placement groove, a plurality of trapezoidal limiting grooves are opened on the middle connecting pipe, and the plurality of trapezoidal limiting strips are respectively engaged and installed in the plurality of trapezoidal limiting grooves.

[0013] In the aforementioned adjustable height building pipe pile for construction engineering, the limiting mechanism includes a limiting rotating shaft fixedly installed on the adjusting screw, and the upper part of the limiting rotating shaft is rotatably installed on the fixed plate. A telescopic limiting rod is fixedly installed between the middle connecting column and the fixed plate.

[0014] In the aforementioned adjustable height construction pipe pile for building construction, the connecting mechanism includes a grouting hole opened in the central connecting column, and telescopic folding retaining rings are fixedly installed on the two fixed plates. The lower part of the telescopic folding retaining rings is fixedly installed on the central connecting column, and the grouting hole is located inside the telescopic folding retaining rings.

[0015] In the aforementioned adjustable height building pipe pile for construction engineering, the positioning mechanism includes multiple mounting plates fixedly installed on the lower part of the sleeve bottom ring, each mounting plate is fixedly installed with an electric telescopic rod, and each electric telescopic rod has a compression positioning plate fixedly installed on its drive end.

[0016] In the aforementioned adjustable height building pipe pile for construction engineering, the linkage mechanism includes a servo motor fixedly installed inside a sleeve bottom ring, a transmission rod rotatably installed inside the sleeve bottom ring, a drive spindle fixedly installed on the drive end of the servo motor, a transmission structure installed between the drive spindle and the transmission rod, and two moving gears respectively fixedly installed on the upper ends of the drive spindle and the transmission rod.

[0017] In the aforementioned adjustable height construction pipe pile for building engineering construction, the transmission structure includes a linkage rod rotatably installed in a sleeved bottom ring, a driven wheel fixedly installed on the linkage rod, a driving wheel fixedly installed on the drive shaft, and a transmission toothed belt fixedly sleeved between the driving wheel and the driven wheel. A transmission gear is fixedly installed on the transmission rod, and the transmission gear cooperates with the transmission toothed belt.

[0018] In the aforementioned adjustable height building pipe pile for construction engineering, the installation mechanism includes two installation columns fixedly installed on the upper pipe pile. Each of the two installation columns is slidably fitted with a traction rope through a traction hole. Two connecting rings are fixedly installed on the bottom ring, and the lower ends of the two traction ropes are respectively fixedly connected to the two connecting rings. Each of the two installation columns is fixedly fitted with a fixing ring.

[0019] Compared with existing technologies, the advantages of this invention are:

[0020] 1. By setting a mid-position connecting pipe, which is installed inside the lower pipe pile and fixed to the upper pipe pile at its upper part, the upper pipe pile can be moved synchronously when the mid-position connecting pipe extends or moves downward. This allows for flexible adjustment of the overall height of the lower pipe pile, the mid-position connecting pipe, and the upper pipe pile, thus achieving overall height adjustment.

[0021] 2: By setting a bottom ring, the bottom ring is slidably fitted onto the outside of the lower pipe pile and fixed to the lower pipe pile by a positioning mechanism. This allows the bottom ring to be slidably removed after the entire pipe pile is placed, so that it can be reused, effectively reducing the overall cost of the pipe pile.

[0022] 3: By setting a fixed gear, after the bottom ring is positioned, the moving gear on it will mesh with the fixed gear. At this time, the servo motor will start and drive the two fixed gears to rotate with the cooperation of the linkage mechanism.

[0023] 4. By setting an adjusting screw, the rotation of the fixed gear will drive the telescopic rotating rod and the adjusting screw to rotate as a whole. When the adjusting screw rotates, it will push up or down, thereby driving the fixed plate and the upper pipe pile to move up and down as a whole. This allows the middle connecting pipe to be pulled out or pulled down, thus realizing the adjustment of the overall length between the lower pipe pile, the middle connecting pipe and the upper pipe pile, and the adjustment of the height of the building pipe pile.

[0024] 5. By setting up a connecting mechanism, the telescopic folding retaining ring inside the connecting mechanism can be adaptively adjusted with the raising and lowering of the upper pipe pile. After the entire building pipe pile is placed, cement can be poured into the lower pipe pile through the upper pipe pile, the telescopic folding retaining ring, and the grouting hole to achieve overall grouting, which can effectively improve the overall stability of the vibration damping pipe pile.

[0025] In summary, this invention, by employing an external driving device to adjust the drive, can achieve overall height adjustment of building pipe piles with high efficiency and stability. Furthermore, the driving device can be used independently and is suitable for adjusting the height of multiple pipe piles, effectively reducing the cost of building pipe piles and having wider adaptability.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Reference Figures 1-2An adjustable height building pipe pile for construction engineering includes a lower pipe pile 1, a middle connecting column 3 fixedly installed inside the lower pipe pile 1, a middle connecting pipe 7 installed inside the lower pipe pile 1 through a sliding mechanism, and an upper pipe pile 2 fixedly installed at the upper end of the middle connecting pipe 7. Two adjusting screws 14 are threadedly installed inside the middle connecting column 3. Two fixing plates 4 are fixedly installed inside the upper pipe pile 2, and a limit mechanism is installed between each fixing plate 4 and the corresponding adjusting screw 14. A communication mechanism is installed between the two fixing plates 4 and the middle connecting column 3.

[0035] The following points are worth noting:

[0036] The sliding mechanism includes an annular placement groove 29 opened in the lower pipe pile 1. Multiple trapezoidal limiting strips are fixedly installed in the annular placement groove 29. Multiple trapezoidal limiting grooves are opened on the middle connecting pipe 7, and the multiple trapezoidal limiting strips are respectively engaged and installed in the multiple trapezoidal limiting grooves. The sliding mechanism is used to ensure that the middle connecting pipe 7 can only slide vertically in the lower pipe pile 1, and will not deviate or separate from the lower pipe pile 1.

[0037] The middle connecting pipe 7 is installed inside the lower pipe pile 1, and its upper part is fixed to the upper pipe pile 2. When the middle connecting pipe 7 extends or moves downward, it can drive the upper pipe pile 2 to move synchronously, so as to flexibly adjust the overall height of the lower pipe pile 1, the middle connecting pipe 7, and the upper pipe pile 2, and realize the adjustment of the overall height.

[0038] The limiting mechanism includes a limiting rotating shaft 15 fixedly installed on the adjusting screw 14, and the upper part of the limiting rotating shaft 15 is rotatably installed on the fixed plate 4. A telescopic limiting rod 13 is fixedly installed between the middle connecting column 3 and the fixed plate 4. The telescopic limiting rod 13 and the limiting rotating shaft 15 in the limiting mechanism play the role of limiting the adjusting screw 14 and the fixed plate 4, so that the fixed plate 4 can only move vertically up and down, and will not rotate with the rotation of the adjusting screw 14.

[0039] The connecting mechanism includes a grouting hole 5 opened in the middle connecting column 3, and telescopic folding retaining rings 6 fixedly installed on two fixing plates 4. The lower part of the telescopic folding retaining rings 6 is fixedly installed on the middle connecting column 3, and the grouting hole 5 is located inside the telescopic folding retaining rings 6. The telescopic folding retaining rings 6 can be adaptively adjusted with the raising and lowering of the upper pipe pile 2. After the entire construction pipe pile is placed, cement can be poured into the lower pipe pile 1 through the upper pipe pile 2, the telescopic folding retaining rings 6, and the grouting hole 5 to achieve overall grouting, which can effectively improve the overall stability of the vibration damping pipe pile.

[0040] Reference Figures 1-4The lower pipe pile 1 is slidably fitted with a bottom ring 8. The lower part of each of the two adjusting screws 14 is fixedly installed with a connecting rod 17. Each connecting rod 17 is rotatably installed with a telescopic rotating rod 16, and the lower end of each of the two telescopic rotating rods 16 is fixedly installed with a fixed gear 9. The bottom ring 8 is fitted with two moving gears 20 through a linkage mechanism, and the two moving gears 20 are respectively engaged with the two fixed gears 9. An installation mechanism is installed between the bottom ring 8 and the upper pipe pile 2.

[0041] The following points are worth noting:

[0042] Multiple positioning mechanisms are installed on the bottom ring 8. The positioning mechanisms include multiple mounting plates 26 fixedly installed on the lower part of the bottom ring 8. Each mounting plate 26 is fixedly installed with an electric telescopic rod 27, and each electric telescopic rod 27 is fixedly installed with a compression positioning plate 28 on its drive end. When the bottom ring 8 moves to a suitable position, the electric telescopic rod 27 will start to push the compression positioning plate 28 to move and press against the outer wall of the lower pipe pile 1. The multiple compression positioning plates 28 cooperate to fix the bottom ring 8 on the lower pipe pile 1.

[0043] The bottom ring 8 is slidably fitted onto the outside of the lower pipe pile 1 and fixed to the lower pipe pile 1 by a positioning mechanism, so that the bottom ring 8 can be slid out after the entire building pipe pile is placed, and can be reused, effectively reducing the overall cost of the building pipe pile.

[0044] The linkage mechanism includes a servo motor 23 fixedly installed inside the sleeve bottom ring 8. A drive spindle 24 is fixedly installed on the drive end of the servo motor 23. A transmission structure is installed between the drive spindle 24 and the transmission rod 18. The transmission structure includes a linkage rod rotatably installed inside the sleeve bottom ring 8. A driven wheel is fixedly installed on the linkage rod. A drive wheel 25 is fixedly installed on the drive spindle 24. A transmission toothed belt 21 is fixedly sleeved between the drive wheel 25 and the driven wheel. When the servo motor 23 starts, it will drive the drive spindle 24 and the drive wheel 25 to rotate. The drive wheel 25 will then drive the transmission toothed belt 21 to rotate as a whole under the cooperation of the transmission wheel.

[0045] A transmission rod 18 is rotatably mounted inside the bottom ring 8. A transmission gear 19 is fixedly mounted on the transmission rod 18, and the transmission gear 19 meshes with the transmission belt 21. Two moving gears 20 are respectively fixedly mounted on the upper ends of the drive spindle 24 and the transmission rod 18. When the transmission belt 21 is in motion, it will drive the meshing transmission gear 19 to rotate, thereby driving the transmission rod 18 to rotate. This enables the servo motor 23 to start and drive the two moving gears 20 to rotate together.

[0046] After the bottom ring 8 is set and positioned, the moving gear 20 on it will mesh with the fixed gear 9. At this time, the servo motor 23 will start and drive the two fixed gears 9 to rotate with the help of the linkage mechanism.

[0047] The rotation of the fixed gear 9 will drive the telescopic rotating rod 16 and the adjusting screw 14 to rotate as a whole. When the adjusting screw 14 rotates, it will push up or down, thereby driving the fixed plate 4 and the upper pipe pile 2 to move up and down as a whole. This will allow the middle connecting pipe 7 to be pulled out or pulled down, thus realizing the adjustment of the overall length between the lower pipe pile 1, the middle connecting pipe 7 and the upper pipe pile 2, and realizing the adjustment of the height of the building pipe pile.

[0048] The installation mechanism includes two installation columns fixedly installed on the upper pipe pile 2. Each of the two installation columns is slidably fitted with a traction rope 10 through a traction hole 12. Two connecting rings 22 are fixedly installed on the bottom ring 8, and the lower ends of the two traction ropes 10 are respectively fixedly connected to the two connecting rings 22. Each of the two installation columns is fixedly installed with a fixing ring 11.

[0049] The fixed lifting ring 11 facilitates the overall hoisting and transfer of the building pipe pile. After the overall height of the building pipe pile is adjusted, the two traction ropes 10 can be pulled up to move the bottom ring 8 upward, thus completing the disassembly and removal of the bottom ring 8 from the building pipe pile.

[0050] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.
