Description

Technical Field

[0001] This invention relates to the field of pipe pile connection technology, specifically a connection device that can increase the horizontal and pull-out resistance of pipe piles. Background Technology

[0002] Currently, prestressed pipe piles in China are usually of equal cross-section or equal diameter and are welded. In on-site operations, after the upper and lower pipe pile sections are aligned, they are fixed by spot welding at the end plates of the upper and lower pipe pile sections. Then, a continuous weld is applied along the joint of the pipe pile end plates. After the weld cools down, the pile is driven or pressed. The welded pile method has good adaptability to axially compressed piles.

[0003] During the welding process of the upper and lower pipe piles, the upper and lower pipe piles need to be aligned and connected. In the construction process, the pipe piles are usually aligned on-site by a crane and then welded directly. However, there will be a certain error when aligning the pipe piles on-site by a crane. Once the error exceeds the range, it is difficult for the staff to detect. If the pipe piles are directly welded and used, the horizontal and vertical resistance of the pipe piles will be reduced. Summary of the Invention

In addition, it can promptly remind workers whether the connection is neat and assist them in making adjustments, thereby improving both connection quality and work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a connecting device that can increase the horizontal and pull-out resistance of pipe piles, comprising an upper pipe pile and a lower pipe pile. The upper pipe pile is provided with a connecting mechanism for easy connection with the lower pipe pile, and the lower pipe pile is provided with an installation mechanism to assist in stable connection with the upper pipe pile. The connecting mechanism is provided with an adjustment mechanism. The connecting mechanism includes a fixed seat fixedly installed inside the upper pipe pile, an extension tube provided below the fixed seat, a spherical push block provided at one end of the extension tube, and a sealing groove fixedly installed inside the lower pipe pile. The spherical push block slides inside the sealing groove and is movably connected to the sealing groove. A sealing block is movably installed inside the spherical push block. The installation mechanism includes an installation plate movable on the sealing groove, and the installation mechanism also includes a first thread and a second thread respectively formed on the upper and lower pipe piles. The adjustment mechanism includes a fixed plate installed on the extension tube, an installation piece movably installed on the fixed plate, and the installation piece is located above the spherical push block.

[0006] Optionally, the extension tube is connected to the spherical push block, and both the extension tube and the spherical push block have cavities inside.

[0007] Optionally, the spherical pusher is hemispherical, and the surface edge of the spherical pusher is in contact with the inner wall of the sealing groove.

[0008] Optionally, a push rod is fixedly installed inside the sealing groove. The push rod is connected through the spherical push block. An exhaust pipe is provided at the bottom of the spherical push block. The push rod is movably connected to the exhaust pipe and slides inside the exhaust pipe.

[0009] Optionally, a sealing block is movably installed inside the exhaust pipe. The sealing block is movably connected to the push rod, and the push rod is pressed together with the sealing block. A vent hole is provided on the sealing block, and the vent hole is movably connected to the inner wall of the exhaust pipe. The inner diameter of the sealing block is 1.1 to 1.5 times the diameter of the push rod.

[0010] Optionally, the mounting mechanism further includes a receiving cavity formed in the sealing groove, the mounting plate has a T-shaped cross-section, the mounting plate moves inside the receiving cavity, and the mounting plate moves with damping inside the receiving cavity.

[0011] Optionally, the first thread is screwed into the second thread.

[0012] Optionally, the fixing plate is fixedly installed on the extension tube, the extension tube has an air jet port, and the fixing plate is located below the air jet port.

[0013] Optionally, the fixed plate has a movable groove, the mounting piece moves inside the movable groove, and one end of the mounting piece is designed not to contact the extension tube.

[0014] Optionally, the mounting plate has a first mounting hole, and the adjustment mechanism further includes a second mounting hole on the mounting plate, with the first mounting hole and the second mounting hole corresponding to each other.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. During the process of aligning one end of the upper pipe pile with the lower pipe pile, the gas pressure can be observed using a gas pressure detector. If the upper and lower pipe piles are not aligned properly, the connection between them will tilt. The upper pipe pile will cause the spherical push block to tilt. Due to the hemispherical design of the spherical push block, once it tilts, the surface edge of the spherical push block will no longer be in contact with the inner wall of the sealing groove. As a result, the inside of the sealing groove will no longer be a sealed space, and the gas pressure inside the sealing groove will change. By detecting the range of gas pressure change inside the sealing groove, the alignment of the connection between the upper and lower pipe piles can be determined. This allows for adaptive adjustments to the positions of the two at the connection point to ensure alignment between the upper and lower pipe piles, improve the connection quality, and enhance the horizontal and vertical resistance of the upper and lower pipe piles.

[0017] 2. In this invention, when the spherical pusher moves to a certain position inside the sealing groove, the push rod will drive the sealing block to slide inside the exhaust pipe, and disconnect the sealing block from the exhaust pipe. When the sealing block slides to a certain position, the gas squeezed inside the sealing groove will flow into the extension pipe and the spherical pusher through the vent hole, and be discharged through the jet nozzle on the extension pipe. Since the jet nozzle on the extension pipe is located on one side of the second thread, the ejected gas can clean the dust and impurities on the second thread, preventing dust and impurities from affecting the screw connection of the first thread and the second thread; and improving the stability of the screw connection of the first thread and the second thread.

[0018] 3. This invention determines the position of the gap between the spherical pusher and the inner wall of the sealing groove by observing which mounting piece is blown by the gas. This allows workers to easily make adjustments. The movement of the mounting piece can also determine the tilt direction of the connection between the upper and lower pipe piles. This not only works in conjunction with a pressure monitoring instrument to promptly alert workers to problems with the alignment of the connection, but also reminds them how to adjust the connection position of the upper and lower pipe piles. On the one hand, it improves the quality of the connection between the upper and lower pipe piles, and on the other hand, it saves workers the trouble of using equipment to check the alignment of the connection between the upper and lower pipe piles, thus improving work efficiency.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 9 The present invention provides a connection device that can increase the horizontal and pull-out resistance of pipe piles, including an upper pipe pile 1 and a lower pipe pile 2. The upper pipe pile 1 is provided with a connection mechanism 3 for easy connection with the lower pipe pile 2. The lower pipe pile 2 is provided with an installation mechanism 4 to assist in the stable connection with the upper pipe pile 1. The connection mechanism 3 is provided with an adjustment mechanism 5.

[0031] The connecting mechanism 3 includes a fixed seat 31 fixedly installed inside the upper pipe pile 1. An extension pipe 32 is provided below the fixed seat 31, and a spherical pusher 35 is provided at one end of the extension pipe 32. The connecting mechanism 3 also includes a sealing groove 33 fixedly installed inside the lower pipe pile 2. The spherical pusher 35 slides inside the sealing groove 33 and is movably connected to the sealing groove 33. A sealing block 37 is movably installed inside the spherical pusher 35. Since the lower pipe pile 2 is buried underground, when welding the upper pipe pile 1 and the lower pipe pile 2, a crane is used on-site to align one end of the upper pipe pile 1 with the lower pipe pile 2, and then the crane drives the upper pipe pile 1 to the lower pipe pile 2. As one end of pile 1 gradually approaches and aligns with the lower pipe pile 2, the upper pipe pile 1 first moves the internal fixed seat 31, which in turn moves the extension tube 32. The extension tube 32 then moves the sealing block 37, allowing the sealing block 37 to be inserted into the sealing groove 33 on the lower pipe pile 2. Since the spherical push block 35 is hemispherical in design, and its diameter is larger than that of the extension tube 32, and smaller than that of the lower pipe pile 2, the spherical push block 35 can be quickly and easily inserted into the sealing groove 33 inside the lower pipe pile 2.

[0032] Alternatively, small holes can be made in the lower pipe pile 2 and the sealing groove 33. The air pressure detector can be placed inside the sealing groove 33 through the small holes, and then the small holes can be sealed.

[0033] As the upper pipe pile 1 gradually aligns with the lower pipe pile 2, the spherical pusher 35 continuously slides inside the sealing groove 33. Since the surface edge of the spherical pusher 35 is in contact with the inner wall of the sealing groove 33, if the upper pipe pile 1 and the lower pipe pile 2 are neatly aligned, the surface edge of the spherical pusher 35 will adhere to the inner wall of the sealing groove 33, creating a sealed space inside the sealing groove 33. Therefore, when the spherical pusher 35 slides, it will compress the internal space of the sealing groove 33, increasing the gas pressure inside the sealing groove 33. This change in gas pressure can be observed using a gas pressure detector. However, if the upper pipe pile 1 and the lower pipe pile 2 are not neatly aligned, the gas pressure inside the sealing groove 33 will increase. If the connection between the upper pipe pile 1 and the lower pipe pile 2 tilts, the upper pipe pile 1 will cause the spherical push block 35 to tilt as well. Due to the hemispherical design of the spherical push block 35, once the spherical push block 35 tilts, the surface edge of the spherical push block 35 will no longer be in contact with the inner wall of the sealing groove 33. As a result, the interior of the sealing groove 33 will no longer be a sealed space, and the gas pressure inside the sealing groove 33 will change. By detecting the range of gas pressure change inside the sealing groove 33, the neatness of the connection between the upper pipe pile 1 and the lower pipe pile 2 can be determined. This can make the upper pipe pile 1 and the lower pipe pile 2 aligned, improve the connection quality between the upper pipe pile 1 and the lower pipe pile 2, and improve the horizontal and pull-out resistance of the upper pipe pile 1 and the lower pipe pile 2.

[0034] Additionally, when the spherical pusher 35 moves to a certain position inside the sealing groove 33, the push rod 34 will contact the spherical pusher 35 and slide into the interior of the exhaust pipe 36. As the spherical pusher 35 continues to move, the push rod 34 will contact and press against the sealing block 37. Since the diameter of the push rod 34 is smaller than the inner diameter of the sealing block 37, the push rod 34 will insert into the interior of the sealing block 37 and can drive the sealing block 37 to slide inside the exhaust pipe 36, thus disconnecting the sealing block 37 from the exhaust pipe 36. When the sealing block 37 slides to a certain position... The vent hole 38 on the sealing block 37 will not seal the connection with the inner wall of the exhaust pipe 36. As a result, the gas squeezed inside the sealing groove 33 will flow into the interior of the extension pipe 32 and the spherical push block 35 through the vent hole 38, and be discharged through the jet nozzle on the extension pipe 32. Since the jet nozzle on the extension pipe 32 is located on one side of the second thread 43, the ejected gas can clean the dust and impurities on the second thread 43, preventing dust and impurities from affecting the screw connection of the first thread 42 and the second thread 43; and improving the stability of the screw connection of the first thread 42 and the second thread 43.

[0035] The mounting mechanism 4 includes a mounting plate 41 that moves on the sealing groove 33. The mounting mechanism 4 also includes a first thread 42 and a second thread 43 respectively opened on the upper pipe pile 1 and the lower pipe pile 2. During the process of the gas inside the sealing groove 33 being discharged through the air jet on the extension pipe 32, the first thread 42 and the second thread 43 on the upper pipe pile 1 are screwed together, thereby increasing the integrity of the connection between the upper pipe pile 1 and the lower pipe pile 2, improving the stability of the connection between the upper pipe pile 1 and the lower pipe pile 2, and improving the horizontal and pull-out resistance.

[0036] The adjustment mechanism 5 includes a fixed plate 51 mounted on the extension pipe 32. An installation plate 52 is movably mounted on the fixed plate 51, positioned above the spherical pusher 35. When the spherical pusher 35 slides, it compresses the internal space of the sealing groove 33, increasing the gas pressure inside the sealing groove 33. The change in gas pressure can be observed using a pressure gauge. If the upper pipe pile 1 and lower pipe pile 2 are not aligned, some gas inside the sealing groove 33 will be ejected through the gap between the spherical pusher 35 and the inner wall of the sealing groove 33. Since the installation plate 52 is positioned above the spherical pusher 35, the ejected gas will blow the installation plate 52, causing it to move on the fixed plate 51. Because multiple sets of installation plates 52 are evenly and dynamically positioned on the fixed plate 51, it is possible to observe which installation plate 52 is being moved by the gas. When the device is blown, the mounting plate 52 will also strike the upper pipe pile 1, producing an abnormal noise, which also serves as an audible warning. In this case, multiple mounting plates 52 can be selected according to the installation accuracy. The position of the gap between the spherical push block 35 and the inner wall of the sealing groove 33 can be determined, which makes it convenient for the staff to make adjustments. The tilt direction of the connection between the upper pipe pile 1 and the lower pipe pile 2 can be determined by which mounting plate 52 moves. This can not only work with the air pressure monitor to promptly remind the staff of any problems with the neatness of the connection, but also remind the staff how to adjust the connection position of the upper pipe pile 1 and the lower pipe pile 2. On the one hand, it improves the quality of the connection between the upper pipe pile 1 and the lower pipe pile 2, and on the other hand, it saves the staff from the operation of borrowing equipment to check the neatness of the connection between the upper pipe pile 1 and the lower pipe pile 2, thus improving work efficiency.

[0037] Furthermore, the extension tube 32 is connected to the spherical push block 35, and both the extension tube 32 and the spherical push block 35 have cavities inside. The spherical push block 35 is hemispherical, and the surface edge of the spherical push block 35 is in contact with the inner wall of the sealing groove 33. A push rod 34 is fixedly installed inside the sealing groove 33, and the push rod 34 is connected through the spherical push block 35. An exhaust pipe 36 is provided at the bottom of the spherical push block 35. The push rod 34 is movably connected to the exhaust pipe 36, and the push rod 34 slides inside the exhaust pipe 36. A sealing block 37 is movably installed inside the exhaust pipe 36, and the sealing block 37 is movably connected to the push rod 34. The push rod 34 and the sealing block 37 are pressed together. A vent hole 38 is provided on the sealing block 37, and the vent hole 38 is movably connected to the inner wall of the exhaust pipe 36. The inner diameter of the sealing block 37 is 1.1 to 1.5 times the diameter of the push rod 34.

[0038] Furthermore, the mounting mechanism 4 also includes a receiving cavity 44 formed in the sealing groove 33, the mounting plate 41 has a T-shaped cross-section, the mounting plate 41 moves inside the receiving cavity 44, and the mounting plate 41 moves with damping inside the receiving cavity 44, and the first thread 42 is screwed to the second thread 43.

[0039] Furthermore, the fixed plate 51 is fixedly mounted on the extension tube 32, which has an air jet nozzle. The fixed plate 51 is located below the air jet nozzle and has a movable groove 55. The mounting piece 52 moves inside the movable groove 55. One end of the mounting piece 52 is designed not to contact the extension tube 32. The mounting piece 52 has a first mounting hole 53. The adjustment mechanism 5 also includes a second mounting hole 54 on the mounting plate 41. The first mounting hole 53 and the second mounting hole 54 are correspondingly arranged. When the spherical push block 35 contacts the push rod 34, the mounting piece 52 contacts the mounting plate 41. The mounting piece 52 is connected to the mounting plate 41 through the first mounting hole 53 and the second mounting hole 54, thus fixing the mounting piece 52 to the mounting plate 41. The upper pipe pile 1 and the lower pipe pile 2 are pre-connected. Then, the upper pipe pile 1 is rotated so that the first thread 42 on the upper pipe pile 1 is screwed into the second thread 43 on the lower pipe pile 2. At the same time, the mounting plate 41 slides into the receiving cavity 44. On the one hand, the upper pipe pile 1 and the lower pipe pile 2 are pre-connected to avoid collisions when the upper pipe pile 1 and the lower pipe pile 2 are aligned, which would cause the connection between the upper pipe pile 1 and the lower pipe pile 2 to be uneven. On the other hand, the pre-connection between the upper pipe pile 1 and the lower pipe pile 2 makes the screwing of the first thread 42 and the second thread 43 smoother and avoids misalignment when the first thread 42 and the second thread 43 are screwed together, thereby improving the stability of the connection between the upper pipe pile 1 and the lower pipe pile 2. After the upper pipe pile 1 and the lower pipe pile 2 are threadedly connected, welding is performed.

[0040] In addition, the mounting plate 52 can be made of a lightweight and high-hardness material, which is convenient for gas blowing and does not affect the connection strength with the mounting plate 41.

[0041] Working principle: Since the lower pipe pile 2 is buried underground, when welding the upper pipe pile 1 and the lower pipe pile 2, one end of the upper pipe pile 1 and the lower pipe pile 2 are aligned on site using a crane. Then, the crane drives one end of the upper pipe pile 1 to gradually approach the lower pipe pile 2 for alignment. During the process of the upper pipe pile 1 gradually approaching the lower pipe pile 2 for alignment, the upper pipe pile 1 first moves the internal fixed seat 31, the fixed seat 31 moves the extension pipe 32, and the extension pipe 32 moves the sealing block 37, so that the sealing block 37 is inserted into the sealing groove 33 on the lower pipe pile 2. Since the spherical push block 35 is hemispherical in design, and the diameter of the spherical push block 35 is larger than the diameter of the extension pipe 32, and the diameter of the spherical push block 35 is smaller than the diameter of the lower pipe pile 2, the spherical push block 35 can be quickly and easily inserted into the sealing groove 33 inside the lower pipe pile 2.

[0042] Alternatively, small holes can be made in the lower pipe pile 2 and the sealing groove 33. The air pressure detector can be placed inside the sealing groove 33 through the small holes, and then the small holes can be sealed.

[0043] As the upper pipe pile 1 gradually aligns with the lower pipe pile 2, the spherical pusher 35 continuously slides inside the sealing groove 33. Since the surface edge of the spherical pusher 35 is in contact with the inner wall of the sealing groove 33, if the upper pipe pile 1 and the lower pipe pile 2 are neatly aligned, the surface edge of the spherical pusher 35 will adhere to the inner wall of the sealing groove 33, creating a sealed space inside the sealing groove 33. Therefore, when the spherical pusher 35 slides, it will compress the internal space of the sealing groove 33, increasing the gas pressure inside the sealing groove 33. This change in gas pressure can be observed using a gas pressure detector. However, if the upper pipe pile 1 and the lower pipe pile 2 are not neatly aligned, the gas pressure inside the sealing groove 33 will increase. If the connection between the upper pipe pile 1 and the lower pipe pile 2 tilts, the upper pipe pile 1 will cause the spherical push block 35 to tilt as well. Due to the hemispherical design of the spherical push block 35, once the spherical push block 35 tilts, the surface edge of the spherical push block 35 will no longer be in contact with the inner wall of the sealing groove 33. As a result, the interior of the sealing groove 33 will no longer be a sealed space, and the gas pressure inside the sealing groove 33 will change. By detecting the range of gas pressure change inside the sealing groove 33, the neatness of the connection between the upper pipe pile 1 and the lower pipe pile 2 can be determined. This can make the upper pipe pile 1 and the lower pipe pile 2 aligned, improve the connection quality between the upper pipe pile 1 and the lower pipe pile 2, and improve the horizontal and pull-out resistance of the upper pipe pile 1 and the lower pipe pile 2.

[0044] Additionally, when the spherical pusher 35 moves to a certain position inside the sealing groove 33, the push rod 34 will contact the spherical pusher 35 and slide into the interior of the exhaust pipe 36. As the spherical pusher 35 continues to move, the push rod 34 will contact and press against the sealing block 37. Since the diameter of the push rod 34 is smaller than the inner diameter of the sealing block 37, the push rod 34 will insert into the interior of the sealing block 37 and can drive the sealing block 37 to slide inside the exhaust pipe 36, thus disconnecting the sealing block 37 from the exhaust pipe 36. When the sealing block 37 slides to a certain position... The vent hole 38 on the sealing block 37 will not seal the connection with the inner wall of the exhaust pipe 36. As a result, the gas squeezed inside the sealing groove 33 will flow into the interior of the extension pipe 32 and the spherical push block 35 through the vent hole 38, and be discharged through the jet nozzle on the extension pipe 32. Since the jet nozzle on the extension pipe 32 is located on one side of the second thread 43, the ejected gas can clean the dust and impurities on the second thread 43, preventing dust and impurities from affecting the screw connection of the first thread 42 and the second thread 43; and improving the stability of the screw connection of the first thread 42 and the second thread 43.

[0045] While the spherical pusher 35 contacts the push rod 34, the mounting plate 52 contacts the mounting disk 41. The mounting plate 52 is connected to the mounting disk 41 through the first mounting hole 53 and the second mounting hole 54, so that the mounting plate 52 and the mounting disk 41 are fixedly connected. This allows the upper pipe pile 1 and the lower pipe pile 2 to be connected in advance. Then, the upper pipe pile 1 is rotated so that the first thread 42 on the upper pipe pile 1 is screwed into the second thread 43 on the lower pipe pile 2. At the same time, the mounting disk 41 slides into the inside of the receiving cavity 44. On the one hand, the upper pipe pile 1 and the lower pipe pile 2 can be pre-connected to avoid collision when the upper pipe pile 1 and the lower pipe pile 2 are aligned, which would cause the upper pipe pile 1 and the lower pipe pile 2 to be connected unevenly. On the other hand, the pre-connection of the upper pipe pile 1 and the lower pipe pile 2 can make the screwing of the first thread 42 and the second thread 43 smoother and avoid misalignment when the first thread 42 and the second thread 43 are screwed together, thereby improving the stability of the connection between the upper pipe pile 1 and the lower pipe pile 2. After the upper pipe pile 1 and the lower pipe pile 2 are threadedly connected, welding is performed.

[0046] During the process of the gas inside the sealing groove 33 being discharged through the jet port on the extension pipe 32, the first thread 42 and the second thread 43 on the upper pipe pile 1 are screwed together, which can increase the integrity of the connection between the upper pipe pile 1 and the lower pipe pile 2, improve the stability of the connection between the upper pipe pile 1 and the lower pipe pile 2, and improve the horizontal and pull-out resistance.

[0047] When the spherical pusher 35 slides, it compresses the internal space of the sealing groove 33, increasing the gas pressure inside the sealing groove 33. This change in gas pressure can be observed using a pressure gauge. If the upper pipe pile 1 and the lower pipe pile 2 are not aligned, some gas inside the sealing groove 33 will be ejected through the gap between the spherical pusher 35 and the inner wall of the sealing groove 33. Since the mounting plate 52 is located above the spherical pusher 35, the ejected gas will blow the mounting plate 52, causing it to move on the fixed plate 51. Because the mounting plates 52 are multiple sets evenly moving on the fixed plate 51, the movement can be observed by checking which mounting plate 52 is moving on the fixed plate 51. The mounting plate 52 is blown by the gas to determine the position of the gap between the spherical pusher 35 and the inner wall of the sealing groove 33. This allows the staff to make adjustments. The direction of the tilt of the connection between the upper pipe pile 1 and the lower pipe pile 2 can be determined by which mounting plate 52 moves. This not only helps the staff to promptly remind them of any problems with the neatness of the connection, but also reminds them how to adjust the connection position of the upper pipe pile 1 and the lower pipe pile 2. On the one hand, it improves the quality of the connection between the upper pipe pile 1 and the lower pipe pile 2, and on the other hand, it saves the staff from having to use the equipment to check the neatness of the connection between the upper pipe pile 1 and the lower pipe pile 2, thus improving work efficiency.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
