Description

Technical Field

[0001] The invention belongs to the field of foundation construction, and in particular relates to a construction device for serially connecting prefabricated concrete piles. Background Art

[0002] During the driving process of precast piles, if the length of a single pile cannot reach the depth specified in the design, it is necessary to connect them in series, that is, connect the precast piles one by one and continue to drive them downward until the designed depth is reached. When driving the piles, the driving angle of the precast piles needs to be set according to the influence of many factors such as geological conditions, pile type and construction method, environment and design requirements. During the driving process, after finding the appropriate driving angle, it is not convenient to maintain the position and driving angle of the precast piles completed for the first time, as well as to provide auxiliary support for the docking process of the newly connected precast piles in the later stage. External equipment is needed for further assistance, and the operation is difficult. Summary of the invention

[0003] In view of this, the present invention aims to propose a construction device for connecting precast concrete piles in series, so as to solve the problem that during the piling process, after finding a suitable piling angle, it is inconvenient to maintain the position and piling angle of the precast piles completed for the first piling, and to provide auxiliary support for the docking process of the newly connected precast piles in the later stage, and further assistance needs to be provided by external equipment, which makes the operation difficult.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A construction device for connecting concrete precast piles in series, comprising a support seat, a turning frame and a pile driver, wherein the end of the support seat is fixedly mounted with a connecting seat rotatably connected to the turning frame, and further comprising: a first toothed disc, the first toothed disc being rotatably mounted at the end of the connecting seat; a support member, the support member being arranged at the edge of the first toothed disc to support the precast pile; a first positioning pin, the first positioning pin passing through the turning frame and the connecting seat and then being plugged into the side wall of the first toothed disc; a positioning gear, the positioning gear being meshed with the first toothed disc; a mounting seat, the mounting seat being rotatably connected with a connecting shaft, the connecting shaft being fixedly plugged into the positioning gear; a locking assembly, the locking assembly being used to lock the positioning gear when the turning frame is rotated to a specified angle, so that the toothed disc of the first toothed disc is in a stationary state relative to the connecting seat; wherein, after the locking assembly locks the first toothed disc, the first positioning pin is unplugged from the first toothed disc, so that the first toothed disc and the supporting member as a whole are separated from the turning frame.

[0006] Furthermore, a first cylinder is rotatably connected between the turning frame and the supporting seat, and the first cylinder is provided to provide power for the turning frame to be turned relative to the supporting seat; a notch is provided on the connecting seat, and a supporting shaft is rotatably connected in the notch, and the first toothed disc is rotatably connected to the surface of the supporting shaft, and both ends of the supporting shaft pass through the connecting seat and are rotatably connected to the turning frame, so as to realize that the turning frame and the first toothed disc are both rotatably connected to the connecting seat; an auxiliary support seat is sleeved on the surface of the pile driver, and the auxiliary support seat is slidably arranged on the turning frame to keep the pile driver parallel to the turning frame;

[0007] It should be understood that during the construction process, the prefabricated pile is connected to the connecting end of the pile driver, the prefabricated pile connected to the pile driver will be supported by the support member, and then the first cylinder provides a turning power to the turning frame, so that the turning frame can be turned to an ideal angle. When the turning frame is at the ideal angle, the prefabricated pile connected to the pile driver is sent into the soil according to the adjusted ideal angle by the pile driver, so as to achieve the piling of the first prefabricated pile, and then the locking assembly locks the positioning gear so that the toothed disc of the first toothed disc is in a stationary state relative to the connecting seat, and the locking assembly locks the first toothed disc. After that, the first locating pin is unplugged from the first toothed disc, so that the first toothed disc and the supporting member are separated from the turning frame as a whole, and then the first precast pile is unconnected from the pile driver, so that the turning frame can turn with the pile driver to a position convenient for connecting to the second precast pile, and then the second precast pile is connected to the pile driver, and the turning frame is turned to the position for the first piling. Since the first precast pile is supported by the supporting member, the piling angle can be maintained, and it can be stably connected with the newly moved second precast pile, which is convenient for serial connection, and the initial piling angle is maintained unchanged, so as to prepare for the second piling.

[0008] It should be further explained that during the entire piling and connection process, the piling angle can be adjusted according to needs, and after the first precast pile is driven, the piling angle of the precast pile can be maintained while the precast pile is supported, and it can be docked in line with the newly moved precast pile to facilitate connection, and the initial piling angle can be maintained unchanged to prepare for the second piling.

[0009] Furthermore, a winder is fixedly installed on the top of the turning frame, a traction rope is wound on the winder, the end of the traction rope is fixedly connected to the top of the pile driver, and the bottom end of the pile driver clamps the prefabricated pile through a clamping assembly.

[0010] Furthermore, an adjustment component is provided between the first positioning pin and the surface of the flip frame, and the adjustment component includes: a first electromagnet, which is fixedly mounted on the side wall of the flip frame; a first magnetic plate, which is fixedly connected to the end of the first positioning pin, and a plug pin is also fixedly connected to the surface, and the plug pin is plugged into the main body of the flip frame; a first supporting spring, which is sleeved on the surface of the first positioning pin, and has two ends fixedly connected to the first magnetic plate and the flip frame respectively; wherein, when the first electromagnet is energized, the magnetic suction plate will be adsorbed to maintain the plug-in state of the first plug pin and the side wall of the first gear disk.

[0011] Specifically, a docking port for docking with the first positioning pin is formed on the surface of the first toothed disc.

[0012] Furthermore, the locking assembly includes: a first damping member, which is fixedly connected to the side wall of the positioning gear; a second magnetic plate, on the surface of which a plurality of plug-in rods are fixedly connected, and after the plurality of plug-in rods pass through the mounting seat, they are fixedly connected to the second damping member, and the second damping member is adapted to the first damping member; a plurality of second supporting springs, which are respectively plugged into the surfaces of the plurality of plug-in rods, and both ends of the plurality of second supporting springs are respectively fixedly connected to the second magnetic plate and the mounting seat; a second electromagnet, which is fixedly mounted on the surface of the mounting seat, and when the second electromagnet remains energized, the second electromagnet attracts the second magnetic plate to maintain the second damping member and the first damping member in a fitted and braked state, so that the positioning gear remains stationary relative to the mounting seat.

[0013] It should be understood that when the first precast pile is in the pile delivery state, the turning angle of the turning frame has been determined, and the first precast pile is supported by the support member. At this time, the second electromagnet is energized, and the second electromagnet attracts the second magnetic plate, and the second magnetic plate supports the second damping member, so that the second damping member and the first damping member are closely fitted, and the second damping member and the first damping member are maintained in a fitted and braked state, so that the positioning gear remains stationary relative to the mounting seat, and the position of the support member connected to the first gear disc is positioned, so that the piling angle of the first precast pile on the support member is determined, and the support of the support member is obtained during the piling process;

[0014] It should be further explained that after the driving angle of the first precast pile is supported and determined, the turning frame is separated from the first toothed disc and the supporting member, and the turning frame can move freely, providing freedom for the installation of the next precast pile, and the next precast pile can be turned over to the angle position of the first turning frame, so as to achieve the co-linear docking of the two precast piles, which helps to reduce the difficulty of docking.

[0015] Furthermore, the construction device for connecting precast concrete piles in series also includes: a first pressure sensor, which is fixedly mounted on the side wall of the flip frame to detect the force applied to the first magnetic plate; a second pressure sensor, which is fixedly mounted on the surface of the mounting seat to detect the force applied to the second magnetic plate; and a controller, which is fixedly mounted on the support seat to control the cancellation of power to the second electromagnet on the premise that the first pressure sensor detects the force applied by the first magnetic plate, and controls the cancellation of power to the first electromagnet on the premise that the second pressure sensor detects the force applied by the second magnetic plate.

[0016] It should be understood that after the piling angle of the precast pile is determined, in order to determine the piling angle, the positions of the support member and the first rotating disk must be determined first. Therefore, it is necessary to first control the locking assembly to lock the positioning gear, and the positioning gear synchronously locks the first toothed disk meshing with itself, thereby realizing the locking of the position of the support member arranged on the first toothed disk. Then, the plug-in limit of the first positioning pin and the first toothed disk is cancelled. If the plug-in of the first positioning pin and the first toothed disk is cancelled first, and then locked by the locking assembly, before the locking assembly is locked, under the action of gravity and other external forces, the support member and the first toothed disk will flip and deviate, which is easy to cause the piling angle to deviate.

[0017] After the pile driving is completed and the turning frame is at the initial ideal angle, the first positioning pin and the first toothed disc should be plugged and positioned so that the support member is at the position relative to the turning frame during the initial installation, and then the locking assembly should be unlocked. Otherwise, the locking assembly should be unlocked first. Under the action of gravity and other external forces, the support member and the first toothed disc will be flipped and offset, and the plugging position of the first positioning pin and the first toothed disc will be offset, resulting in the inability to complete the plugging and positioning.

[0018] Based on the above needs, a first pressure sensor, a second pressure sensor and a controller are set. Only when the first pressure sensor detects the force applied by the first magnetic plate for detection, can the controller be used to control the cancellation of power to the second electromagnet, so as to ensure that the first toothed disc has been positioned relative to the flip frame before the locking assembly is locked. Only when the second pressure sensor detects the force applied by the second magnetic plate, can the controller be used to control the cancellation of power to the first electromagnet, and the plug-in positioning of the first toothed disc relative to the flip frame by the first positioning pin be cancelled, which is beneficial for the supporting effect of the support member to always be in an ideal state, and to provide a guarantee for the switching process of the support member during the first pile delivery process and the later pile driving and docking process, so as to avoid operational errors.

[0019] Compared with the prior art, the construction device for connecting precast concrete piles in series according to the present invention has the following beneficial effects:

[0020] (1) In the construction device for connecting concrete precast piles in series described in the present invention, the piling angle can be adjusted according to demand during the entire piling and connecting process, and after the first precast pile is driven, the piling angle of the precast pile can be maintained while the precast pile is supported, which is conducive to preparing for the stable docking of the newly moved precast pile, facilitating the connecting, and maintaining the initial piling angle unchanged to prepare for subsequent piling.

[0021] (2) The construction device for connecting concrete precast piles in series described in the present invention maintains the second damping member in a braking state in contact with the first damping member, so that the positioning gear remains stationary relative to the mounting seat, and the position of the support member connected to the first toothed disc is positioned, thereby determining the piling angle of the first precast pile on the support member, and obtaining support from the support member during the piling process. After the piling angle of the first precast pile is determined, the flip frame is separated from the first toothed disc and the support member as a whole, and the flip frame can move freely, providing freedom for the installation of the next precast pile.

[0022] (3) The construction device for connecting concrete precast piles in series described in the present invention is provided with a first pressure sensor, a second pressure sensor and a controller. Only when the first pressure sensor detects the force applied by the first magnetic plate for detection, can the controller be used to control the second electromagnet to be de-energized, thereby ensuring that the first toothed disc has been positioned relative to the flip frame before the locking assembly is locked. Only when the second pressure sensor detects the force applied by the second magnetic plate, can the controller be used to control the first electromagnet to be de-energized, thereby canceling the plug-in positioning of the first toothed disc relative to the flip frame by the first positioning pin. This is beneficial for the supporting function of the supporting member to always be performed in an ideal state, and provides a good guarantee for the switching process of the supporting member during the first pile delivery process and the later pile driving and docking process, thereby avoiding operational errors.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] like Figure 1-Figure 5 As shown, in one embodiment, a construction device for connecting concrete precast piles in series includes a support seat 1, a turning frame 2 and a pile driver 3. The end of the support seat 1 is fixedly installed with a connecting seat 4 that is rotatably connected to the turning frame 2, and also includes: a first toothed disc 5, which is rotatably installed at the end of the connecting seat 4; a support member, which is arranged at the edge of the first toothed disc 5 to support the precast pile 48; a first positioning pin 6, which passes through the turning frame 2 and the connecting seat 4 and is inserted into the side wall of the first toothed disc 5; a positioning gear 7, which is a positioning gear The wheel 7 is meshed with the first toothed disc 5; a mounting seat 16, on which a connecting shaft 1601 is rotatably connected, and the connecting shaft 1601 is fixedly plugged into the positioning gear 7; a locking assembly, which is used to lock the positioning gear 7 when the flip frame 2 is rotated to a specified angle, so that the toothed disc of the first toothed disc 5 is in a stationary state relative to the connecting seat 4; wherein, after the locking assembly locks the first toothed disc 5, the first positioning pin 6 is unplugged from the first toothed disc 5, so that the first toothed disc 5 and the supporting member as a whole are detached from the flip frame 2.

[0044] Specifically, a first cylinder 8 is rotatably connected between the turning frame 2 and the support seat 1. By setting the first cylinder 8, power is provided for the turning frame 2 to be turned relative to the support seat 1; a notch is provided on the connecting seat 4, and a support shaft 9 is rotatably connected in the notch, and the first toothed disc 5 is rotatably connected to the surface of the support shaft 9. Both ends of the support shaft 9 penetrate the connecting seat 4 and are rotatably connected to the turning frame 2, so as to realize that the turning frame 2 and the first toothed disc 5 are both rotatably connected to the connecting seat 4; an auxiliary support seat 10 is sleeved on the surface of the pile driver 3, and the auxiliary support seat 10 is slidably set on the turning frame 2 to keep the pile driver 3 parallel to the turning frame 2;

[0045] It should be understood that during the construction process, the prefabricated pile 48 is connected to the connecting end of the pile driver 3, and the prefabricated pile 48 connected to the pile driver 3 will be supported by the support member, and then the first cylinder 8 provides a turning power to the turning frame 2, so that the turning frame 2 can turn to an ideal angle. When the turning frame 2 is at the ideal angle, the prefabricated pile 48 connected to the pile driver 3 is sent into the soil according to the adjusted ideal angle by the pile driver 3, so that the first prefabricated pile 48 is driven. Then, the locking assembly locks the positioning gear 7, so that the gear disc of the first gear disc 5 is in a stationary state relative to the connecting seat 4. After the locking assembly locks the first gear disc 5 , unplug the first locating pin 6 from the first toothed disc 5, so that the first toothed disc 5 and the supporting member are separated from the turning frame 2 as a whole, and then unplug the first precast pile 48 from the pile driver 3, so that the turning frame 2 can be turned with the pile driver 3 to a position convenient for connecting the second precast pile 48, and then the second precast pile 48 is connected to the pile driver 3, and the turning frame 2 is turned to the position for the first piling. Since the first precast pile 48 is supported by the supporting member, the piling angle can be maintained, and it can be stably docked with the newly moved second precast pile 48, which is convenient for serial connection, and the initial piling angle is maintained unchanged, so as to prepare for the second piling.

[0046] It should be further explained that during the entire piling and connection process, the piling angle can be adjusted according to demand, and after the first precast pile 48 is driven, while the precast pile 48 is supported, the piling angle of the precast pile 48 can be maintained, and it can be stably docked with the newly moved precast pile 48, which is convenient for connection, and the initial piling angle is maintained unchanged to prepare for subsequent piling.

[0047] Specifically, a winder 11 is fixedly installed at the top of the turning frame 2, and a traction rope 12 is wound on the winder 11. The end of the traction rope 12 is fixedly connected to the top of the pile driver 3, and the bottom end of the pile driver 3 clamps the prefabricated pile 48 through a clamping assembly.

[0048] It should be understood that during the process of the pile driver 3 delivering piles, the traction rope 12 needs to be paid out by the winder 11. Under the action of gravity, the pile driver 3 can move along the turning frame 2 to achieve the purpose of delivering piles.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Fig.10As shown, as an embodiment of further optimization of the present invention, an adjustment component is arranged between the first positioning pin 6 and the surface of the flip frame 2, and the adjustment component includes: a first electromagnet 13, the first electromagnet 13 is fixedly mounted on the side wall of the flip frame 2; a first magnetic plate 14, the first magnetic plate 14 is fixedly connected to the end of the first positioning pin 6, and a plug pin 1401 is also fixedly connected on the surface, and the plug pin 1401 is plugged into the main body of the flip frame 2; a first support spring 15, the first support spring 15 is sleeved on the surface of the first positioning pin 6, and the two ends are respectively fixedly connected to the first magnetic plate 14 and the flip frame 2; wherein, when the first electromagnet 13 is energized, the magnetic suction plate will be adsorbed to maintain the plug-in state of the first plug pin 1401 and the side wall of the first toothed disc 5.

[0050] It should be understood that when the pile is delivered for the first time, after the flipping angle of the flip frame 2 is determined, after the locking assembly locks the first toothed disc 5, when it is necessary to cancel the connection between the first positioning pin 6 and the first toothed disc 5, the first electromagnet 13 is energized, the first electromagnet 13 is de-energized, the first electromagnet 13 will lose its magnetic force, and under the support of the first supporting spring 15, the first magnetic plate 14 will drive the first positioning pin 6 to move, canceling the connection with the first toothed disc 5, and when docking is required, the first electromagnet 13 can be completed by restoring power to the first electromagnet 13.

[0051] Specifically, a docking port for docking with the first positioning pin 6 is formed on the surface of the first toothed disc 5 .

[0052] like Figure 4 , Figure 5 and Fig.13 As shown, as an optional embodiment of the present invention, the locking assembly includes: a first damping member 17, the first damping member 17 is fixedly connected to the side wall of the positioning gear 7; a second magnetic plate 18, a plurality of plug-in rods 19 are fixedly connected to the surface of the second magnetic plate 18, and the plurality of plug-in rods 19 are fixedly connected to the second damping member 20 after passing through the mounting seat 16, and the second damping member 20 is adapted to the first damping member 17; a plurality of second supporting springs 21, the plurality of second supporting springs 21 are respectively plugged into the surfaces of the plurality of plug-in rods 19, and the two ends of the plurality of second supporting springs 21 are respectively fixedly connected to the second magnetic plate 18 and the mounting seat 16; a second electromagnet 22, the second electromagnet 22 is fixedly mounted on the surface of the mounting seat 16, and when the second electromagnet 22 is powered on, the second electromagnet 22 attracts the second magnetic plate 18, maintains the second damping member 20 and the first damping member 17 in a fitted and braked state, so that the positioning gear 7 remains stationary relative to the mounting seat 16.

[0053] It should be understood that when the first precast pile 48 is in the pile delivery state, the flip angle of the flip frame 2 has been determined, and the first precast pile 48 is supported by the support member. At this time, the second electromagnet 22 is energized, and the second electromagnet 22 will attract the second magnetic plate 18, and the second magnetic plate 18 will support the second damping member 20, so that the second damping member 20 and the first damping member 17 are closely fitted, and the second damping member 20 and the first damping member 17 are kept in a fitted and braked state, so that the positioning gear 7 remains stationary relative to the mounting seat 16, and the position of the support member connected to the first gear disc 5 is positioned, so that the piling angle of the first precast pile 48 on the support member is determined, and the support of the support member is obtained during the piling process;

[0054] It should be further explained that after the piling angle of the first precast pile 48 is supported and determined, the flip frame 2 is separated from the first gear disc 5 and the support member, and the flip frame 2 can move freely, providing freedom for the installation of the next precast pile 48, and the next precast pile 48 can be flipped to the angle position of the first flip frame 2 flip, so as to achieve the co-linear docking of the two precast piles 48, which helps to reduce the difficulty of docking.

[0055] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Fig.10 and Fig.13 As shown, as an embodiment of further optimization of the present invention, it also includes: a first pressure sensor 23, the first pressure sensor 23 is fixedly mounted on the side wall of the flip frame 2 to detect the force applied to the first magnetic plate 14; a second pressure sensor 24, the second pressure sensor 24 is fixedly mounted on the surface of the mounting seat 16 to detect the force applied to the second magnetic plate 18; a controller 25, the controller 25 is fixedly mounted on the support seat 1, and is used to control the cancellation of power to the second electromagnet 22 on the premise that the first pressure sensor 23 detects the force applied by the first magnetic plate 14, and to control the cancellation of power to the first electromagnet 13 on the premise that the second pressure sensor 24 detects the force applied by the second magnetic plate 18.

[0056] It should be understood that after the piling angle of the precast pile 48 is determined, in order to determine the piling angle, the positions of the support member and the first rotating disk must be determined first. Therefore, it is necessary to first control the locking assembly to lock the positioning gear 7, and the positioning gear 7 synchronously locks the first toothed disk 5 meshing with itself, thereby realizing the locking of the position of the support member arranged on the first toothed disk 5. Then, the plug-in limit of the first positioning pin 6 and the first toothed disk 5 is cancelled. If the plug-in of the first positioning pin 6 and the first toothed disk 5 is cancelled first, and then locked by the locking assembly, before the locking assembly is locked, under the action of gravity and other external forces, the support member and the first toothed disk 5 will flip and deviate, which is easy to cause the piling angle to deviate.

[0057] After the pile driving is completed and the turning frame 2 is at the initial ideal angle, the first positioning pin 6 and the first toothed disc 5 should be plugged and positioned so that the support is at the position relative to the turning frame 2 during the initial installation, and then the locking assembly should be unlocked. Otherwise, the locking assembly should be unlocked first. Under the action of gravity and other external forces, the support and the first toothed disc 5 will be flipped and offset, and the plugging position of the first positioning pin 6 and the first toothed disc 5 will be offset, making it impossible to complete the plugging and positioning.

[0058] Based on the above needs, a first pressure sensor 23, a second pressure sensor 24 and a controller 25 are set. Only when the first pressure sensor 23 detects the force applied by the first magnetic plate 14, can the controller 25 be used to control the cancellation of the power to the second electromagnet 22, so as to ensure that the first toothed disc 5 has been positioned relative to the flip frame 2 before the locking assembly is locked. Only when the second pressure sensor 24 detects the force applied by the second magnetic plate 18, can the controller 25 be used to control the cancellation of the power to the first electromagnet 13, and the cancellation of the plug-in positioning of the first positioning pin 6 on the first toothed disc 5 relative to the flip frame 2, which is beneficial to the support of the support member always being in an ideal state, and to provide a good guarantee for the switching process of the support member during the first pile delivery process and the later pile driving and docking process, so as to avoid operational errors.

[0059] like Figure 1 , Figure 3 and Fig.10 As shown, as a further optimized embodiment of the present invention, it also includes a limiting plate 26, and the limiting plate 26 is fixedly connected to the surface of the first toothed disc 5.

[0060] It should be understood that after the first prefabricated pile 48 is driven, the first toothed disc 5 is separated from the turning frame 2, and the limit plate 26 is supported by the first toothed disc 5 and maintains its position unchanged, so that when the turning frame 2 is turned over and adjusted next time, it will be limited by the limit plate 26, which is helpful to prevent the turning frame 2 from turning over excessively.

[0061] like Figure 1 , Figure 3 and Fig.10 As shown, as an optional embodiment of the present invention, the support member includes: a support platform 27, the support platform 27 is fixedly connected to the surface of the first gear disk 5, and the end portion has a first supporting arc surface; two first supporting claws 28, the two first supporting claws 28 are symmetrically rotatably connected to the end portion of the support platform 27, the clamping surfaces of the two first supporting claws 28 are both second supporting arc surfaces, and the second supporting arc surfaces and the first supporting arc surfaces are both rotatably connected with rollers 29; two second cylinders 30, the two second cylinders 30 are respectively fixedly mounted on both sides of the first gear disk 5, and the output ends are rotatably mounted with connecting rods 49, and the ends of the two connecting rods 49 away from the second cylinders 30 are respectively rotatably connected to the surfaces of the two first supporting claws 28. It should be understood that in the process of supporting the prefabricated pile 48, the connecting rod 49 is first pulled by the second cylinder 30, and the connecting rod 49 simultaneously pulls the two first supporting claws 28 to rotate, so that the two first supporting claws 28 are opened to facilitate the placement of the prefabricated pile 48. When the prefabricated pile 48 is placed, the two second cylinders 30 are started to pull the connecting rod 49, so that the two first supporting claws 28 are moved closer to surround the prefabricated pile 48 to achieve support, and under the action of the roller 29, the prefabricated pile 48 can be rolled and supported to avoid excessive friction when the pile is delivered.

[0062] like Figure 6 and Figure 7 As shown, as an optional embodiment of the present invention, it also includes a docking sleeve 31 and a plug-in sleeve 32. The docking sleeve 31 is fixedly installed on the top end of the prefabricated pile 48 by bolts, and the plug-in sleeve 32 is fixedly connected to the bottom end of the prefabricated pile 48 by bolts.

[0063] Specifically, Figure 6 and Figure 7 As shown, the surfaces of the docking sleeve 31 and the plug sleeve 32 are provided with plug holes 33, and the plug holes 33 between the docking sleeve 31 and the plug sleeve 32 are plugged and positioned by a boss-type plug pin 34;

[0064] After the boss-type plug 34 is inserted and positioned between the plug-in hole 33 between the docking sleeve 31 and the plug-in sleeve 32, two wrapping plates 35 are put on the surface of the docking sleeve 31, and the two wrapping plates 35 are locked and positioned by bolts to prevent the boss-type plug 34 from detaching from the plug-in hole 33, thereby realizing the connection between the two prefabricated piles 48.

[0065] like Fig.10 , Fig.11 and Fig.12As shown, as an embodiment of the present invention that can be further optimized, the surface of the plug-in sleeve 32 has an annular groove 36, and the top ends of the two first support claws 28 are each provided with three mounting grooves 37, and auxiliary support members are provided in the three mounting grooves 37, and the auxiliary support members include: a slide 38, the slide 38 is slidably set in the mounting groove 37 shown, and a connecting rod 39 is inserted at the bottom end, the connecting rod 39 is fixedly connected to the inner bottom end of the mounting groove 37, and a third support spring 40 is sleeved on the surface, and the two ends of the third support spring 40 are respectively fixedly connected to the slide 38 and the inner wall of the mounting groove 37; an auxiliary support wheel 41, and the auxiliary support wheel 41 is rotatably connected to the slide 38.

[0066] It should be understood that after each pile delivery is completed, when the precast pile 48 that has just been delivered needs to be connected in series with a new precast pile 48, a section of the top of the precast pile 48 will be exposed to prepare for docking. After the precast pile 48 that has just been delivered is disconnected from the pile driver 3, it may sink into the soil under the action of gravity. By providing an auxiliary support wheel 41, the precast pile 48 is supported in the pile delivery state to maintain rolling support. The docking sleeve 31 at the top of the precast pile 48 sinks in time with the precast pile 48. When the docking sleeve 31 moves to the auxiliary support wheel 41, under the action of the third support spring 40, the auxiliary support wheel 41 will be pushed into the annular groove 36 to form an obstruction, which is conducive to preventing the precast pile 48 from further sinking.

[0067] It should be further explained that a limiting tooth 4101 is provided on the edge of the auxiliary support wheel 41; the auxiliary support member also includes a tooth plate 50, which is fixedly connected to the inner wall of the mounting groove 37 near the clamping surface. The tooth plate 50 is made of rubber. When the auxiliary support wheel 41 is in an obstructing state, the limiting tooth 4101 on the auxiliary support wheel 41 will stick to the tooth plate 50, thereby limiting the rotational freedom of the auxiliary support wheel 41 relative to the slide seat 38, which is beneficial for the auxiliary support wheel 41 to maintain a certain stability when obstructing the annular groove 36 of the docking sleeve 31.

[0068] like Figure 1 , Figure 8 and Fig. 9 As shown, as an optional embodiment of the present invention, the clamping assembly includes: a threaded rod 42, the threaded rod 42 is fixedly connected to the connection end of the pile driver 3 connected to the prefabricated pile 48; a plurality of inner clamping jaws 43, the plurality of inner clamping jaws 43 are slidably inserted on the surface of the threaded rod 42 at the bottom end of the pile driver 3, and the surfaces of the plurality of inner clamping jaws 43 have oblique grooves 44; a plurality of traction pins 45, the plurality of traction pins 45 are respectively slidably inserted in the oblique grooves 44 of the plurality of inner clamping jaws 43, and the top end is fixedly connected with a connecting ring 46, the top of the connecting ring 46 is rotatably connected with a threaded sleeve 47, and the threaded sleeve 47 is threadedly connected to the surface of the threaded rod 42.

[0069] It should be understood that when it is necessary to install the prefabricated pile 48 on the pile delivery device 3, the multiple inner clamping claws 43 are inserted into the inner ring space of the docking sleeve 31 at the top of the prefabricated pile 48, and then the threaded sleeve 47 is rotated, the threaded sleeve 47 will move upward, synchronously driving the connecting ring 46 to move, and the connecting ring 46 synchronously drives the multiple traction pins 45 to move upward synchronously, acting on the inclined groove 44, so that the multiple inner clamping claws 43 move outward to clamp the inside of the docking sleeve 31 to achieve connection. When it needs to be disassembled, the threaded sleeve 47 is rotated to move the threaded sleeve 47 downward to complete the clamping, which is convenient and quick.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
