[0053] Examples, such as Figure 1-Figure 5 As shown, a pile frame system is used for offshore construction of pipe piles; the pile frame system includes:

[0054] The basic platform 100 is arranged in a horizontal direction.

[0055] The lower pile frame 210 is disposed on one side of the base platform 100 along the vertical direction, and the bottom end of the lower pile frame 210 is fixedly connected to the base platform 100 .

[0056] The upper pile frame 220 is disposed above the lower pile frame 210, and the bottom end of the upper pile frame 220 is hinged to the top end of the lower pile frame 210, so that the upper pile frame 220 has a piling position and an avoidance position.

[0057] The rear pouring cylinder 230 is arranged on one side of the lower pile frame 210. The bottom end of the rear pouring cylinder 230 is hinged to the lower pile frame 210, and the top end of the rear pouring cylinder 230 is hinged to the upper pile frame 220. The rear pouring cylinder 230 can drive the upper pile frame 220 to flip back and forth between the piling position and the avoidance position around the top end of the lower pile frame 210.

[0058] The rear pull rod 240 is obliquely arranged above the base platform 100 , and the bottom end of the rear pull rod 240 is fixedly connected to the base platform 100 , and the top end of the rear pull rod 240 is fixedly connected to the lower pile frame 210 .

[0059] The fixed pulley 250 is fixedly mounted on the ends of the lower pile frame 210 and the upper pile frame 220 .

[0060] The winch 260 is fixedly installed on the basic platform 100, and the steel wire rope of the winch 260 passes through the fixed pulley 250 and is fixedly connected to the pile hammer 270 on one side of the upper pile frame 220. The winch 260 is used to drive the pile hammer 270 to rise.

[0061] The pile body 200 in the present application adopts a two-stage structure and is composed of an upper pile frame 220 and a lower pile frame 210, and the bottom end of the upper pile frame 220 is hinged to the top end of the lower pile frame 210. At the same time, a rear tilting cylinder 230 is provided on one side of the pile body 200, and the two ends of the rear tilting cylinder 230 are respectively hinged to the upper pile frame 220 and the lower pile frame 210. The upper pile frame 220 can be reciprocated around the bottom end by the telescopic drive of the rear tilting cylinder 230, so that the upper pile frame 220 has a working position that is convenient for the pile hammer 270 to hammer the pipe pile 400 and a avoidance position that is convenient for the pipe pile 400 to be hoisted, thereby avoiding the influence of the pile hammer 270 on the hoisting operation of the pipe pile 400, facilitating the hoisting operation of the pipe pile 400, and shortening the offshore pile foundation construction period.

[0062] In a specific embodiment, if Figure 1 and Figure 3 As shown, fixed pulleys 250 are installed at the top and bottom of the upper pile frame 220, and a fixed pulley 250 is installed at the bottom end of the lower pile frame 210. The steel wire rope of the winch 260 passes around the fixed pulleys 250 at three positions and is fixedly connected to the pile hammer 270 on one side of the upper pile frame 220; at the same time, a buffer block 221 is provided on one side of the upper pile frame 220 close to the pile hammer 270.

[0063] Such arrangement is because: during the process of the upper pile frame 220 flipping and switching between the working position and the avoidance position, the fixed pulley 250 at the bottom end of the upper pile frame 220 or the fixed pulley 250 at the top end of the lower pile frame 210 can keep the wire rope of the winch 260 in a tensioned state at all times to ensure the smooth movement of the pile hammer 270; at the same time, a buffer block 221 is installed on the upper pile frame 220, and the buffer block 221 can play a buffering role between the upper pile frame 220 and the pile hammer 270 to prevent the pile hammer 270 from hitting the upper pile frame 220 and causing damage to the upper pile frame 220 during the flipping process of the upper pile frame 220.

[0064] In a specific implementation, Figure 1 , Figure 3 As shown, a shelf 280 is provided above the basic platform 100, and the shelf 280 is fixedly connected to the top of the lower pile frame 210, and the shelf 280 can vertically support the upper pile frame 220 in the avoidance position, that is, under the action of the rear pouring cylinder 230, the upper pile frame 220 can be flipped from a vertical state to a horizontal state, and the upper pile frame 220 in a horizontal state is placed on the shelf 280, so as to support and fix the upper pile frame 220 through the shelf 280.

[0065] It should be noted that: in the present application, the hinge point of the upper pile frame 220 and the lower pile frame 210 is located on the side of the pile body 200 away from the pile hammer 270, so that when the upper pile frame 220 is turned up counterclockwise to a vertical state, the lower end surface of the upper pile frame 220 is exactly coplanar with the upper end surface of the lower pile frame 210, and the upper pile frame 220 is in the working position at this time. When the upper pile frame 220 is turned down clockwise at an appropriate angle, the pile hammer 270 is completely located on the right side of the left side of the upper pile frame 220, and the pile hammer 270 at this time will not interfere with the hanging operation of the pipe pile 400, that is, the upper pile frame 220 is in a evasive position.

[0066] Preferably, the shelf 280 is a tripod.

[0067] This arrangement is because: the triangle has good stability and can guarantee the supporting effect of the shelf frame 280 on the upper pile frame 220 to the greatest extent.

[0068] In a specific implementation, Figure 5 As shown, a pile gripper 290 is installed at the middle and lower part of the lower pile frame 210 .

[0069] In a specific implementation, Figure 1 , Figure 3As shown, the bottom end of the lower pile frame 210 is hinged to the base platform 100; the rear pull rod 240 is tilted above the base platform 100, the top end of the rear pull rod 240 is hinged to the lower pile frame 210, the bottom end of the rear pull rod 240 is hinged to the base platform 100, and the axial length of the rear pull rod 240 is adjustable to adjust the angle between the lower pile frame 210 and the horizontal plane, that is, to adjust the angle between the pile body 200 and the horizontal plane.

[0070] The reason for such arrangement is that: in the actual construction process, the pile frame system is fixedly installed on the pile driving ship, but the inclination angle of the hull is different at different times and under different wind and wave conditions. In this embodiment, the bottom end of the pile body 200 is hingedly connected to the base platform 100, and a rear tie rod 240 with adjustable axial length is installed between the pile body 200 and the base platform 100. By adjusting the axial length of the rear tie rod 240, the angle between the pile body 200 and the horizontal plane can be adjusted, that is, the pile frame system has the ability to change amplitude forward and backward, can adapt to different hull inclination angles, and thus ensure the verticality of the pipe pile 400.

[0071] Specifically, Figure 1 , Figure 3 As shown, the rear tie rod 240 includes a coaxially arranged inclined tie rod 241 and a variable-length oil cylinder 242, the top end of the inclined tie rod 241 is hinged to the top end of the lower pile frame 210, the bottom end of the inclined tie rod 241 is fixedly connected to the top end of the variable-length oil cylinder 242, and the bottom end of the variable-length oil cylinder 242 is hinged to the base platform 100, so that the axial length of the rear tie rod 240 can be adjusted by extending and retracting the variable-length oil cylinder 242.

[0072] In a specific implementation, Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the base platform 100 includes a longitudinal moving platform 110, which is installed in parallel above the longitudinal rails 310 of the hull 300. The number of the longitudinal rails 310 is two, and the two longitudinal rails 310 are arranged in parallel along the longitudinal direction.

[0073] The longitudinal movement platform 110 can slide on the longitudinal rail 310, and a longitudinal movement cylinder 120 is provided between the longitudinal movement platform 110 and the longitudinal rail 310. The longitudinal movement cylinder 120 is arranged along the longitudinal direction, and one end of the longitudinal movement cylinder 120 is fixedly connected to the longitudinal movement platform 110, and the other end of the longitudinal movement cylinder 120 is connected to a movable connection component 130, and the movable connection component 130 can be detachably fixedly connected to the longitudinal rail 310; a fixed connection component 140 is installed on the longitudinal movement platform 110, and the fixed connection component 140 can be detachably fixedly connected to the longitudinal rail 310.

[0074] This arrangement is because: the longitudinal movement cylinder 120 is installed between the longitudinal movement platform 110 and the longitudinal track 310, and the movable connection assembly 130 detachably and fixedly connects the other end of the longitudinal movement cylinder 120 to the longitudinal track 310, one end of the longitudinal movement cylinder 120 is fixedly connected to the longitudinal movement platform 110, and the longitudinal movement platform 110 is fixedly connected to the longitudinal track 310 through the fixed connection assembly 140. When the fixed connection assembly 140 is in a locked state, the longitudinal movement platform 110 is fixedly connected to the longitudinal track 310 as a whole, and the longitudinal movement platform 110 is locked and fixed on the longitudinal track 310 by the fixed connection assembly 140, so that the longitudinal movement platform 110 will not move due to the movement of the hull 300. When the fixed connection component 140 is in an unlocked state, the longitudinal movement platform 110 and the longitudinal track 310 can move relative to each other in the longitudinal direction. At this time, if the dynamic connection component 130 is in an unlocked state, the longitudinal movement cylinder 120 and the longitudinal track 310 can move relative to each other in the longitudinal direction. The longitudinal movement cylinder 120 can be extended and retracted to drive the dynamic connection component 130 to move longitudinally relative to the longitudinal track 310, and then the dynamic connection component 130 is changed from an unlocked state to a locked state, that is, the other end of the longitudinal movement cylinder 120 is fixedly connected to the longitudinal track 310 through the dynamic connection component 130; at this time, the longitudinal movement platform 110 and the longitudinal track 310 can be driven to move relative to each other by the extension and retraction of the longitudinal movement cylinder 120, thereby realizing the adjustment of the longitudinal position of the longitudinal movement platform 110.

[0075] Preferably, Figure 4 As shown, a plurality of plug-in positioning holes (not shown in the figure) are linearly arranged along the longitudinal direction on the longitudinal rail 310; the movable connection assembly 130 includes a movable slider 131, a movable latch pin 132 and a movable latch pin cylinder 133, the movable slider 131 is fixedly connected to the other end of the longitudinal displacement cylinder 120, and a through hole is provided on the movable slider 131 along the vertical direction; the movable latch pin cylinder 133 is fixedly installed above the movable slider 131, the movable latch pin 132 is arranged directly below the movable slider 131, the top end of the movable latch pin 132 extends axially into the through hole of the movable slider 131, and the top end of the movable latch pin 132 is fixedly connected to the piston rod end of the movable latch pin cylinder 133, so as to drive the movable latch pin 132 to be inserted and withdrawn from the plug-in positioning hole through the telescopic movement of the movable latch pin cylinder 133.

[0076] The fixed connection assembly 140 includes a fixed sliding block 141, a fixed latch pin 142 and a fixed latch pin cylinder 143. The fixed sliding block 141 is located at one end of the longitudinal movement cylinder 120 and is fixedly connected to the longitudinal movement platform 110, and a through hole is provided on the fixed sliding block 141 in the vertical direction; the fixed latch pin cylinder 143 is fixedly installed above the fixed sliding block 141, and the fixed latch pin 142 is arranged directly below the fixed sliding block 141. The top end of the fixed latch pin 142 extends axially to the through hole of the fixed sliding block 141, and the top end of the fixed latch pin 142 is fixedly connected to the piston rod end of the fixed latch pin cylinder 143, so that the fixed latch pin 142 can be inserted and withdrawn from the plug-in positioning hole by the telescopic drive of the fixed latch pin cylinder 143.

[0077] More preferably, Figure 3 , Figure 4 As shown, the base platform 100 also includes a transverse platform 150, which is arranged above the longitudinal platform 110 and can be moved transversely. A transverse oil cylinder 160 is arranged between the transverse platform 150 and the longitudinal platform 110, and the connection method between the transverse oil cylinder 160 and the transverse platform 150 and the longitudinal platform 110 is the same as the connection method between the longitudinal oil cylinder 120 and the longitudinal platform 110 and the longitudinal rail 310, which will not be repeated here. At the same time, the winch 260 is fixedly installed on the transverse platform 150.

[0078] It should be noted that the longitudinal direction in the present application refers to the longitudinal direction of the hull 300, and the transverse direction in the present application refers to the transverse direction of the hull 300, that is, the front and rear direction in the present application.

[0079] Compared with the prior art, this application has at least the following beneficial technical effects:

[0080] The upper pile frame and the pile hammer in the present application can be tilted backwards, so that the pile hammer can avoid the pile position, which not only facilitates the hanging and placing operation of the pipe pile, but also lowers the center of gravity of the pile frame system.

[0081] The pile driving frame system in the present application has the ability of front and rear amplitude adjustment, can adapt to different hull inclination angles, and ensure the verticality of the pipe pile.

[0082] The pile driving frame system in the present application has the ability to move longitudinally and transversely, and can make fine adjustments to each pile position, which can not only ensure the pile driving accuracy, but also enable one pile driving frame to cover multiple pile positions, thereby reducing the number of ship moves.

[0083] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
