Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a mechanical pile splicing construction device. Background Technology

[0002] Currently, as a type of precast concrete component, pipe piles are widely used in the foundations of large-scale projects such as high-rise buildings, bridges, and port terminals due to their advantages such as high single pile bearing capacity, fast construction speed, and stable quality.

[0003] In actual engineering projects, the length of a single section of pipe pile is limited due to constraints in transportation and construction equipment. Therefore, during the pile driving process, multiple sections of pipe pile must be joined together section by section using a connection process to achieve the designed pile length.

[0004] Pipe pile connection is a key process in pipe pile construction, and its quality directly determines the bearing capacity and durability of the entire pile foundation. However, the traditional pipe pile connection method is mainly welding connection. This method requires high technical skills from the operators, the weld quality is greatly affected by human factors, and the on-site welding speed is slow. It is also difficult to construct in bad weather, which can easily affect the construction cycle. Summary of the Invention

[0005] This application provides a mechanical pile splicing construction device that can reduce the impact on the construction cycle, and adopts the following technical solution: A mechanical pile splicing construction device includes a lower pipe pile, an upper pipe pile, and a connecting mechanism installed between the lower pipe pile and the upper pipe pile. The connecting mechanism includes a first connecting plate bolted to the top of the lower pipe pile and a second connecting plate bolted to the top of the upper pipe pile. Two insert plates are fixedly connected to the bottom of the second connecting plate, and two slots are opened on the top of the first connecting plate. The two insert plates are respectively inserted into the two slots. A first through hole is opened at the bottom of the two slots, and an automatic fixing component for fixing the two insert plates is installed in the first through hole.

[0006] To address this, when connecting the lower and upper pipe piles, the upper pipe pile is first hoisted onto the lower pipe pile using a lifting device. At this point, two insert plates are inserted into two slots, and an automatic fixing assembly automatically secures the two insert plates. This shortens the connection time between the lower and upper pipe piles, thus reducing the impact on the construction schedule. Furthermore, the two insert plates and two slots facilitate the positioning of the first and second connecting plates. This ensures that when the lower and upper pipe piles are joined, their central axes are aligned, preventing eccentricity. Consequently, the joint does not bear additional bending moments under stress, reducing the likelihood of breakage at the joint.

[0007] Preferably, the automatic fixing assembly includes two mounting brackets bolted to the bottom of the first connecting plate, two rotating rods rotatably connected to the two mounting brackets respectively, and two threaded rods fixed to the top of the two rotating rods respectively; the bottom of the two insert plates is provided with threaded grooves, and the two threaded rods are threadedly connected to the two threaded grooves respectively; the automatic fixing assembly also includes a driving component for driving the two rotating rods to rotate.

[0008] In response, when the insert plate is inserted into the slot, the driving component drives the two rotating rods to rotate. The rotation of the two driving rods enables the two threaded rods to be threadedly connected to the two moving insert plates, thereby facilitating the automatic fixation of the two insert plates. In summary, the automatic fixation component facilitates the automatic fixation of the two insert plates.

[0009] Preferably, the driving component includes a driving plate fixed to the bottom of the second connecting plate, a second through hole opened in the first connecting plate for the driving plate to pass through, two driving tubes respectively sleeved on the two rotating rods, a receiving plate installed on the outer side wall of the two driving tubes, and a support plate bolted to the bottom of the two mounting brackets; the bottom of the driving plate abuts against the top of the receiving plate, and a plurality of support springs are fixedly connected between the receiving plate and the support plate; a plurality of spiral blocks are fixedly connected to the outer side wall of the rotating rods, and a plurality of spiral grooves are opened on the inner wall of the driving tubes, with the plurality of spiral blocks and the plurality of spiral grooves corresponding to each other.

[0010] In response, when the first connecting plate and the second connecting plate are connected, the driving plate is inserted into the second through hole and drives the receiving plate to move downward. The downward movement of the receiving plate drives the two driving tubes to move downward. Then, the two driving tubes drive the two rotating rods to rotate under the action of the spiral block and the spiral groove, respectively. In summary, the driving component is designed to facilitate the rotation of the two rotating rods.

[0011] Preferably, a vertical rod is fixed to the bottom of the receiving plate, the vertical rod passes through the support plate, and the vertical rod is slidably connected to the support plate.

[0012] The vertical rods are designed to guide the movement of the receiving plate, which in turn facilitates the movement of the drive tube.

[0013] Preferably, the bottom of the support plate is equipped with two sets of abutment components. Each set of abutment components includes a first sliding sleeve fixed to the bottom of the support plate, a movable rod slidably connected to the first sliding sleeve, an abutment plate fixed to one end of the movable rod, and a first spring sleeved on the movable rod. The end of the movable rod away from the abutment plate is provided with a spherical surface, which matches the side wall of the vertical rod. The two ends of the first spring are respectively fixed to the inner sides of the abutment plate and the first sliding sleeve.

[0014] To address this, when the receiving plate moves downward under the action of the driving plate, it drives the moving rod downward. Then, under the action of the spherical surface, the vertical rod drives the moving rod to move closer to the inner wall of the lower pipe pile. The movement of the moving rod closer to the inner wall of the lower pipe pile causes the abutment plate to move closer to the inner wall of the lower pipe pile. This allows the abutment plate to abut against the inner wall of the lower pipe pile, thereby improving the stability between the first connecting plate and the lower pipe pile. Furthermore, the included first spring facilitates the limiting of the moving rod, ensuring that the moving rod initially stops at the position corresponding to the spherical surface and the vertical rod.

[0015] Preferably, a sealing mechanism is provided between the first connecting plate and the second connecting plate. The sealing mechanism includes a first annular groove and a second annular groove formed between the first connecting plate and the second connecting plate. An annular plate is slidably connected in the first annular groove. A sealing ring is fixedly connected to the top of the annular plate and is engaged with the second annular groove. A movable ring is fixedly connected to the bottom of the annular plate. A third through hole for the movable ring to move is provided at the bottom of the first annular groove. Two sets of transmission components for driving the movable ring to move upward are installed in the second connecting plate.

[0016] In response, when the insert plate is inserted into the slot, the transmission component drives the moving ring to move upward. The upward movement of the moving ring drives the annular plate to move upward, and the upward movement of the annular plate drives the sealing ring to move upward. This allows the sealing ring to engage with the second annular groove, thereby improving the sealing performance between the first connecting plate and the second connecting plate. Consequently, it reduces the possibility of uneven force distribution between the first connecting plate and the second connecting plate due to the entry of foreign objects.

[0017] Preferably, the two sets of transmission components are respectively configured for two insert plates. Each set of transmission components includes a fourth through hole opened in the side wall of the slot and communicating with the third through hole, a fixed rod fixed to the inner wall of the fourth through hole, a second sliding sleeve slidably connected to the fixed rod, a second spring sleeved to the fixed rod, and a limiting ring threaded to one end of the fixed rod. The two ends of the second spring abut against the second sliding sleeve and the limiting ring, respectively. A push plate is fixedly connected to the top of the second sliding sleeve. The push plate has a first inclined surface at the end near the insert plate, and the first inclined surface matches the side wall of the insert plate. The bottom of the moving ring has an annular second inclined surface, and the second inclined surface matches the end of the push plate away from the insert plate.

[0018] In response, when the insert plate is inserted into the slot, the insert plate drives the push plate to move closer to the moving ring under the action of the first inclined surface, and then the push plate drives the moving ring to move upward under the action of the second inclined surface. In summary, the transmission component is designed to facilitate the upward movement of the moving ring. In addition, the second spring is designed to limit the second sliding sleeve, which in turn limits the push plate, so that the push plate in the initial state can stay at the position corresponding to the first inclined surface and the insert plate.

[0019] Preferably, a sealing plate is bolted to the end of the fourth through hole away from the slot.

[0020] The sealing plate installed in this way can reduce the entry of foreign objects into the fourth through hole.

[0021] In summary, this application has the following beneficial effects: When connecting the lower and upper pipe piles, the upper pipe pile is first hoisted onto the lower pipe pile using a lifting device. At this point, two insert plates are inserted into two slots, and then an automatic fixing assembly automatically secures the two insert plates. This shortens the connection time between the lower and upper pipe piles, thus reducing the impact on the construction cycle. Furthermore, the two insert plates and two slots facilitate the positioning of the first and second connecting plates. This ensures that when the lower and upper pipe piles are joined, their central axes are aligned, preventing eccentricity. Consequently, the joint does not bear additional bending moments under stress, reducing the likelihood of joint breakage. Attached Figure Description

[0028] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0029] This application discloses a mechanical pile splicing construction device, such as... Figure 1 As shown, it includes a lower pipe pile 1, an upper pipe pile 2, and a connecting mechanism 3 installed between the lower pipe pile 1 and the upper pipe pile 2.

[0030] like Figure 1 and Figure 2As shown, the connecting mechanism 3 includes a first connecting plate 31 bolted to the top of the lower pipe pile 1 by countersunk bolts and a second connecting plate 32 bolted to the top of the upper pipe pile 2 by countersunk bolts. Two insert plates 33 are fixed to the bottom of the second connecting plate 32. Two slots 311 are formed at the top of the first connecting plate 31, and the two insert plates 33 are respectively inserted into the two slots 311. A first through hole 312 is formed at the bottom of the two slots 311, and an automatic fixing component 4 for fixing the two insert plates 33 is installed in the first through hole 312. When it is necessary to connect the lower pipe pile 1 and the upper pipe pile 2, the upper pipe pile 2 is first lifted onto the lower pipe pile 1 using a hoisting device. At this time, the two insert plates 33 are respectively inserted into the two slots 311, and then the automatic fixing component 4 can automatically fix the two insert plates 33, thereby shortening the connection time between the lower pipe pile 1 and the upper pipe pile 2, and thus reducing the impact on the construction cycle. In addition, the two insert plates 33 and two slots 311 facilitate the positioning of the first connecting plate 31 and the second connecting plate 32. This ensures that when the lower pipe pile 1 and the upper pipe pile 2 are connected, the central axes of the lower pipe pile 1 and the upper pipe pile 2 are on a straight line and there will be no eccentricity. As a result, the joint will not bear additional bending moment when under stress, thus reducing the possibility of joint breakage.

[0031] like Figure 2 and Figure 3 As shown, the automatic fixing assembly 4 includes two mounting brackets 41 bolted to the bottom of the first connecting plate 31, two rotating rods 42 vertically rotatably connected to the two mounting brackets 41 via bearings, and two threaded rods 43 fixed to the top of the two rotating rods 42. The threaded rods 43 are coaxially arranged with the rotating rods 42. The bottom of the two insert plates 33 is provided with threaded grooves 331, and the two threaded rods 43 are threadedly connected to the two threaded grooves 331. The automatic fixing assembly 4 also includes a driving component for driving the two rotating rods 42 to rotate. When the insert plate 33 is inserted into the slot 311, the driving component drives the two rotating rods 42 to rotate. The rotation of the two driving rods enables the two threaded rods 43 to be threadedly connected to the two movable insert plates 33, thereby facilitating the automatic fixing of the two insert plates 33. In summary, the automatic fixing assembly 4 facilitates the automatic fixing of the two insert plates 33.

[0032] like Figures 2-4As shown, the driving component includes a driving plate 44 vertically fixed to the bottom of the second connecting plate 32, a second through hole 313 opened in the first connecting plate 31 for the driving plate 44 to pass through vertically, two driving tubes 45 vertically sleeved on the two rotating rods 42 respectively, a receiving plate 46 horizontally installed on the outer side wall of the two driving tubes 45, and a support plate 47 bolted to the bottom of the two mounting brackets 41; the bottom of the driving plate 44 abuts against the top of the receiving plate 46, and a plurality of support springs 48 are vertically fixed between the receiving plate 46 and the support plate 47; a plurality of spiral blocks 421 are fixed to the outer side wall of the rotating rods 42, and a plurality of spiral grooves 451 are opened on the inner wall of the driving tubes 45, with the plurality of spiral blocks 421 and the plurality of spiral grooves 451 corresponding and matching one-to-one. When the first connecting plate 31 and the second connecting plate 32 are connected, the driving plate 44 is inserted into the second through hole 313 and drives the receiving plate 46 to move downward. The downward movement of the receiving plate 46 drives the two driving tubes 45 to move downward. Then, the two driving tubes 45 drive the two rotating rods 42 to rotate under the action of the spiral block 421 and the spiral groove 451 respectively. In summary, the driving component is designed to facilitate the rotation of the two rotating rods 42.

[0033] like Figure 2 and Figure 3 As shown, a vertical rod 49 is vertically fixed to the bottom of the receiving plate 46. The vertical rod 49 passes through the support plate 47 and slides vertically to the support plate 47. The vertical rod 49 facilitates the guidance of the movement of the receiving plate 46, and thus facilitates the guidance of the movement of the drive tube 45.

[0034] like Figure 1 , Figure 3 and Figure 5As shown, two sets of abutment components 5 are installed at the bottom of the support plate 47. Each set of abutment components 5 includes a first sliding sleeve 51 fixed to the bottom of the support plate 47, a moving rod 52 that slides radially along the lower pipe pile 1 and is connected to the first sliding sleeve 51, an abutment plate 53 fixed to one end of the moving rod 52, and a first spring 54 horizontally sleeved on the moving rod 52. A spherical surface 521 is provided at the end of the moving rod 52 away from the abutment plate 53, and the spherical surface 521 matches the side wall of the vertical rod 49. The two ends of the first spring 54 are respectively fixed to the inner sides of the abutment plate 53 and the first sliding sleeve 51. When the receiving plate 46 moves downward under the action of the driving plate 44, the receiving plate 46 drives the moving rod 52 to move downward. Then, the vertical rod 49, under the action of the spherical surface 521, drives the moving rod 52 to move closer to the inner wall of the lower pipe pile 1. The movement of the moving rod 52 closer to the inner wall of the lower pipe pile 1 drives the abutment plate 53 to move closer to the inner wall of the lower pipe pile 1. This allows the abutment plate 53 to abut against the inner wall of the lower pipe pile 1, thereby improving the stability between the first connecting plate 31 and the lower pipe pile 1. In addition, the first spring 54 is provided to limit the movement rod 52, so that the moving rod 52 in the initial state can stay at the position corresponding to the spherical surface 521 and the vertical rod 49.

[0035] like Figure 2 and Figure 3 As shown, a sealing mechanism 6 is provided between the first connecting plate 31 and the second connecting plate 32. The sealing mechanism 6 includes a first annular groove 61 and a second annular groove 62 opened between the first connecting plate 31 and the second connecting plate 32. An annular plate 63 is vertically slidably connected in the first annular groove 61. A sealing ring 64 is fixedly connected to the top of the annular plate 63. The sealing ring 64 is engaged in the second annular groove 62. When the sealing ring 64 is engaged in the second annular groove 62, both ends of the sealing ring 64 are respectively in the first annular groove 61 and the second annular groove 62. A movable ring 65 is fixedly connected to the bottom of the annular plate 63. A third through hole 611 is opened at the bottom of the first annular groove 61 for the movable ring 65 to move vertically. Two sets of transmission components 7 for driving the movable ring 65 to move upward are installed in the second connecting plate 32. When the insert plate 33 is inserted into the slot 311, the transmission assembly 7 drives the moving ring 65 to move upward. The upward movement of the moving ring 65 drives the annular plate 63 to move upward, and the upward movement of the annular plate 63 drives the sealing ring 64 to move upward. This allows the sealing ring 64 to engage with the second annular groove 62, thereby improving the sealing performance between the first connecting plate 31 and the second connecting plate 32. Consequently, it reduces the possibility of uneven force distribution between the first connecting plate 31 and the second connecting plate 32 due to the entry of foreign objects.

[0036] like Figure 2 and Figure 3As shown, two sets of transmission components 7 are respectively set for two insert plates 33. Each set of transmission components 7 includes a fourth through hole 71 opened in the side wall of the slot 311 and communicating with the third through hole 611, a fixing rod 72 horizontally fixed to the inner wall of the fourth through hole 71, a second sliding sleeve 73 slidably connected to the fixing rod 72 in the horizontal direction, a second spring 74 horizontally sleeved to the fixing rod 72, and a limiting ring 75 threaded to one end of the fixing rod 72. The two ends of the second spring 74 abut against the second sliding sleeve 73 and the limiting ring 75 respectively. A push plate 76 is fixedly connected to the top of the second sliding sleeve 73. A first inclined surface 761 is provided at the end of the push plate 76 near the insert plate 33. The first inclined surface 761 matches the side wall of the insert plate 33. A second inclined surface 651 is provided at the bottom of the moving ring 65. The second inclined surface 651 matches the end of the push plate 76 away from the insert plate 33. When the insert plate 33 is inserted into the slot 311, the insert plate 33 drives the push plate 76 to move closer to the moving ring 65 under the action of the first inclined surface 761. Then, the push plate 76 drives the moving ring 65 to move upward under the action of the second inclined surface 651. In summary, the transmission component 7 facilitates driving the moving ring 65 to move upward. In addition, the second spring 74 facilitates limiting the second sliding sleeve 73, and thus facilitates limiting the push plate 76. This allows the push plate 76 in the initial state to stay at the position corresponding to the first inclined surface 761 and the insert plate 33.

[0037] like Figure 2 As shown, a recessed groove 711 is provided at the end of the fourth through hole 71 away from the slot 311. A sealing plate 77 is bolted to the recessed groove 711 by a countersunk bolt. The sealing plate 77 can reduce the entry of foreign objects into the fourth through hole 71.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
