Description

Technical Field

[0001] This invention relates to the field of steel pipe pile technology, specifically to an auxiliary handling system for steel pipe piles based on a crane vessel and its handling process. Background Technology

[0002] Concrete-filled steel pipe piles, due to the constraint of the internal concrete by the external steel pipe, put the concrete in a triaxial stress state, which greatly improves its strength, plasticity and toughness, and has good ductility. They are particularly suitable for bridges and wharves in areas with thick soft soil cover.

[0003] Steel-concrete composite piles are typically fabricated in a factory and then transported as a whole by a crane vessel. Upon arrival at the designated location, the crane vessel's crane lifts the steel-concrete composite piles horizontally one by one onto its vertical pile-erecting device. The vertical pile-erecting device then rotates the piles to a vertical position and transfers them to the crane vessel's impact-driven pile-driving device. The impact-driven pile-driving device then drives the steel-concrete composite piles one by one. Finally, concrete is poured, vibrated, and cured to obtain the steel-concrete composite pile. However, existing methods generally have the following drawbacks: 1) Partial lifting... 1) Some crane ships use a dispersed placement method for steel pipe piles. Although this makes it easier for the crane to lift the steel pipe piles one by one onto the vertical pile device, this method has a small carrying capacity and low work efficiency. 2) Some crane ships use an overall stacking method for steel pipe piles. Although this saves space and increases carrying capacity, this method requires lifting the steel pipe piles one by one from the top layer onto the vertical pile device. This requires manual labor at high altitudes to tie the lifting equipment to the corresponding steel pipe piles one by one, and then the crane to lift them one by one. This poses a risk of repeated high-altitude operations, which is not only unsafe, but also inefficient due to repeated high-altitude operations.

[0004] Furthermore, steel pipe piles are prone to deformation after being placed horizontally for a period of time. To address this issue, reinforcing supports are typically installed inside the steel pipe piles to prevent deformation. However, when the steel pipe piles are flipped by the vertical pile device, the reinforcing supports must be manually removed, a time-consuming and labor-intensive process. Therefore, these problems urgently need to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a steel pipe pile auxiliary handling system and its handling process based on a crane ship. By using the hoisting components, placement plate I, placement plate II, wire rope, winch, material handling mechanism and crane in a coordinated manner, not only can several steel pipe piles be stacked in an orderly manner in the frame for overall transportation, saving space, but it is also convenient to move the steel pipe piles out of the frame one by one and hoist them onto the vertical pile device in a low-altitude operation state. This process is time-saving and labor-saving, avoids high-altitude operation, and has high safety.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an auxiliary handling system for steel pipe piles based on a crane vessel, the innovation of which lies in: including a frame, placement plate I, placement plate II, lifting components, a lifting mechanism, and a material handling mechanism; the crane vessel is arranged along the forward and backward directions, and a hollow rectangular frame is horizontally and longitudinally arranged on its deck relative to one side of the vertical pile device; on the deck of the crane vessel, placement plates I are symmetrically arranged horizontally at intervals relative to the interior of the frame, and placement plates II are horizontally aligned directly above each placement plate I within the frame; the two placement plates II are lifted by the lifting mechanism within the frame relative to the placement plate I. The area directly above the placement plate I is raised and lowered synchronously; several horizontally arranged steel pipe piles are also arranged in parallel and laterally spaced on the two placement plates I and the two placement plates II, and hoisting components are symmetrically sleeved on both ends of each steel pipe pile, so that each steel pipe pile is supported on the corresponding two placement plates I or two placement plates II by the corresponding hoisting components; on the deck of the crane ship, there are also material picking mechanisms symmetrically spaced between the frame and the vertical pile device, and the steel pipe piles are moved out of the frame one by one by the horizontal and vertical synchronous movement of the two material picking mechanisms, and then hoisted onto the vertical pile device one by one by the crane and lifting equipment on the crane ship.

[0007] Preferably, the frame includes vertical tubes, horizontal tube I, horizontal tube II, horizontal reinforcing tubes, vertical reinforcing tubes, longitudinal reinforcing tubes, and transverse reinforcing tubes; two horizontal tubes II are arranged symmetrically in a horizontal direction with a gap between them, and horizontal tubes I are welded horizontally and longitudinally aligned at both ends between the two horizontal tubes II, forming a rectangular structure arranged horizontally and longitudinally; vertical tubes are also vertically aligned at both ends of the lower surface of each horizontal tube II, and the four vertical tubes are arranged symmetrically in a rectangle, and the frame is fixed to the deck of the crane vessel through the vertical tubes; horizontal reinforcing tubes are also welded horizontally or longitudinally aligned at the upper middle position between each pair of adjacent vertical tubes, and the distance between each horizontal reinforcing tube and the deck of the crane vessel must be greater than the height of the lifting assembly, and must ensure the material handling... The mechanism removes the steel pipe piles from the frame without interference. Vertical reinforcing pipes are welded sequentially and vertically at intervals along the length between each horizontal reinforcing pipe and its corresponding horizontal pipe I or horizontal pipe II. The stability of the frame is ensured through the cooperation of the horizontal and vertical reinforcing pipes. Several horizontally arranged transverse reinforcing pipes are welded sequentially and horizontally at intervals between two horizontal pipe I and in the area between two horizontal pipe II. Furthermore, several horizontally arranged longitudinal reinforcing pipes are welded sequentially and vertically at intervals along the length between each adjacent transverse reinforcing pipe, between the foremost transverse reinforcing pipe and the foremost horizontal pipe II, and between the last transverse reinforcing pipe and the last horizontal pipe II. The stability of the frame is further ensured through the cooperation of the transverse and longitudinal reinforcing pipes.

[0008] Preferably, each of the lifting components includes an upper cover, a lower cover, a connecting plate, a lifting lug II, a support block I, and a rubber roller; a lower cover is also provided at both ends of each steel pipe pile directly below its stress point, each lower cover being a U-shaped structure matching the steel pipe pile, with its opening facing upwards, and ensuring that its opening slots are all arranged horizontally; a support block I is also horizontally provided at the middle of the inner bottom surface of each lower cover, and a groove matching the steel pipe pile is embedded in the upper surface of each support block I. The system includes an arc-shaped groove I, each of which is coaxially arranged with the corresponding steel pipe pile. Within each arc-shaped groove I, several horizontally longitudinally arranged rubber rollers are sequentially spaced along the arc direction. Each rubber roller is rotatably connected to the corresponding support block I around its own axis. Each steel pipe pile passes horizontally and longitudinally through the corresponding two lower covers, and its stress points are supported within the arc-shaped groove I of the corresponding support block I. Thus, the corresponding steel pipe pile is supported by the cooperation of the lower covers, support blocks I, and rubber rollers. An upper cover is horizontally aligned with each lower cover on the upper surface of each steel pipe pile. Each upper cover is a U-shaped structure that matches the steel pipe pile, and its bottom surface size is consistent with that of each lower cover. The opening slot of each upper cover is set along the horizontal longitudinal direction, and its opening end is set downward. Adjacent upper and lower covers are screwed together by connecting plates to form a hollow cuboid structure that is open at the front and back. After the steel pipe pile passes through the corresponding hollow cuboid structure horizontally, it is supported on the rubber rollers in the corresponding arc-shaped groove I. Lifting lugs II are vertically welded on the front and back sides and near the bottom of each upper and lower cover. The lifting lugs II are used to lift the corresponding upper or lower cover, and it is ensured that the lifting lugs II do not interfere with the action of the steel pipe pile being supported horizontally on the corresponding placement plate I or placement plate II by the lifting components.

[0009] Preferably, each of the above-mentioned upper cover also includes a second fixing plate, a reinforcing plate, a second electric push rod, a clamping plate, and a first rubber pad; the height of each upper cover is greater than the height of the corresponding lower cover, and it must be ensured that the position of the connecting plate does not interfere with the corresponding lifting lug II; a second fixing plate is also horizontally and vertically symmetrically arranged at a position slightly below the middle of the left and right inner sides of each upper cover, and every two adjacent second fixing plates are respectively spaced apart on the left and right sides of the corresponding steel pipe pile; a reinforcing plate is also vertically arranged between the lower surface of each second fixing plate and the corresponding inner side of the upper cover, and the corresponding second fixing plate is fixed and reinforced by the reinforcing plate; a second electric push rod is also horizontally arranged on the upper surface of each second fixing plate, and each of the above-mentioned upper cover also includes a second fixing plate, a reinforcing plate, a second electric push rod, a clamping plate, and a first rubber pad; the height of each upper cover is greater than the height of the corresponding lower cover, and it must be ensured that the position of the connecting plate does not interfere with the position of the corresponding lifting lug II; a second fixing plate is also horizontally and vertically arranged at a position slightly below the middle of the left and right inner sides of each upper cover, and every two adjacent second fixing plates are respectively spaced apart on the left and right sides of the corresponding steel pipe pile; a reinforcing plate is also vertically arranged between the lower surface of each second fixing plate and the corresponding inner side of the upper cover, and the reinforcing plate is used to fix and reinforce the corresponding second fixing plate; a second electric push rod is also horizontally arranged on the upper surface of each second fixing plate, and a second electric push rod is also arranged between the lower surface of each upper cover and the corresponding lower cover II; a second fixing plate is also horizontally and horizontally arranged between the lower surface of each upper cover and the corresponding lower cover II; a second electric push rod is also horizontally and horizontally arranged between the lower surface of each upper cover and the corresponding lower cover II; a second fixing plate is also horizontally and horizontally arranged between the lower surface of each upper The tail ends of the two electric push rods are fixedly mounted on the upper surface of the corresponding second fixed plate by stiffening plates, and their pushing ends are respectively set towards the center direction of the corresponding steel pipe pile, and are respectively screwed and fixed to the corresponding clamping plates set vertically in the longitudinal direction; a first rubber pad is also fixedly attached to the side of each clamping plate near the steel pipe pile, and under the drive of the corresponding second electric push rod, the first rubber pad on each clamping plate is in close contact with the corresponding position on the surface of the corresponding steel pipe pile, thereby limiting the left and right direction of the corresponding steel pipe pile; the pushing end of each second electric push rod must ensure that the clamping plate can contact the surface of the corresponding steel pipe pile at its extreme extension position, and its retraction limit position must ensure that the clamping plate is disengaged from the corresponding steel pipe pile, and does not interfere with the rotation of the steel pipe pile around its own axis.

[0010] Preferably, the lifting mechanism includes a winch, a wire rope, and lifting lugs I; the front placement plate I is positioned directly below all the lifting components arranged in the same horizontal direction relative to the front side, and the rear placement plate I is positioned directly below all the lifting components arranged in the same horizontal direction relative to the rear side; the length and width of each placement plate I match the length and width of the corresponding placement plate II, and they are all spaced apart within the frame, ensuring that the frame does not interfere with the vertical up-and-down movement of all the upper steel pipe piles with the placement plate II; on the upper surface of each placement plate I, a placement groove I matching the bottom surface of the lower cover is vertically embedded in each lifting component position relative to the lower layer, and the depth of each placement groove I is less than the depth of the lower surface of the lower cover and the corresponding upper surface. The vertical spacing between the lifting lugs II, through the cooperation of the lower cover and the corresponding placement groove I, horizontally positions each steel pipe pile placed on the placement plate I, ensuring that all steel pipe piles in the lower layer are horizontally and longitudinally spaced and aligned in the same horizontal plane; on the upper surface of each placement plate II, a placement groove II matching the bottom surface of the lower cover is vertically embedded relative to each lifting component position in the upper layer, and the opening depth of each placement groove II is less than the vertical spacing between the lower surface of the lower cover and its corresponding lifting lug II, thus, through the cooperation of the lower cover and the corresponding placement groove II, horizontally positions each steel pipe pile placed on the placement plate II, ensuring that all steel pipe piles in the upper layer are horizontally and longitudinally spaced and aligned in the same horizontal plane; Lifting lugs I are welded symmetrically and perpendicularly at intervals on the left and right sides of each placement plate II. Winches are also installed on the inner top surface of the frame, positioned relative to the left and right sides of each placement plate II, ensuring that each winch is positioned directly above each pair of adjacent lifting lugs I. The four winches operate synchronously, and each winch is equipped with two horizontally coaxially arranged drums. Steel wire ropes are wound around the two drums of each winch, thereby connecting one end of each set of steel wire ropes on each winch to the corresponding two... With the lifting lug I connected, the two placement plates II can move vertically up and down synchronously through the synchronized winding and unwinding actions of the four winches, and all the steel pipe piles on the upper layer can be raised and lowered synchronously with the placement plate II. The lowering limit position of the two placement plates II must ensure that the placement plate II can be lowered to a position close to the corresponding placement plate I, and that the steel pipe piles on the placement plate II can be removed from the frame by the material handling mechanism. The rising limit position of the two placement plates II must ensure that the placement plate II is detached from the lower layer hoisting components, and that it does not interfere with the material handling mechanism's action of removing the steel pipe piles on the placement plate I from the frame.

[0011] Preferably, each of the material handling mechanisms includes a lower base plate, a lifting assembly, an upper top plate, a support block II, a second slide rail, a second slider, a second motor, a second gear, a second rack, and a second limiting block; a horizontally arranged lower base plate is symmetrically positioned between the frame and the vertical pile device relative to the area between the two placement plates I, and a horizontally arranged second slide rail is symmetrically positioned between the front and rear of each lower base plate on the deck of the crane ship, with the right end of each second slide rail extending to the right near the vertical pile device and the left end extending to the left into the interior of the frame, and is arranged horizontally and longitudinally collinear with the left side of each placement plate I; a second slider matching the second slide rail is symmetrically positioned on the lower surface of each lower base plate relative to the position of each second slide rail, and the lower base plate moves horizontally by means of the cooperation of the second slide rail and the second slider; a second slide rail is fixed at the left and right ends of each second slide rail on the deck of the crane ship. A second limiting block is provided to limit the horizontal movement of the lower base plate. A second rack is horizontally positioned on the deck of the crane vessel, directly below each lower base plate and between two corresponding second slide rails. The length of each second rack is the same as the length of each second slide rail, and they are aligned. The teeth of each second rack are horizontally positioned facing forward and are fixed to the deck of the crane vessel by stiffeners. A second motor is vertically positioned on the upper surface of each lower base plate, relative to the position of the corresponding second rack. Each second motor is positioned on the right side of the upper surface of the corresponding lower base plate, and the two second motors operate synchronously. The output end of each second motor extends vertically downwards from the lower surface of the corresponding lower base plate and is connected to the corresponding second rack via a second gear. Driven by the second motors, the two lower base plates move horizontally synchronously through the meshing of the second gear and the corresponding second rack. Above each of the lower base plates, a matching upper top plate is horizontally aligned. Between each upper top plate and its corresponding lower base plate, symmetrically spaced at intervals relative to the left side of the second motor, lifting components are arranged. The four lifting components operate synchronously, enabling the two upper top plates to move vertically up and down synchronously. A support block II is horizontally positioned in the middle of the upper surface of each upper top plate. Two support blocks II are symmetrically arranged, and each support block II has an arc-shaped groove II embedded in its upper surface, matching the steel pipe pile. Each arc-shaped groove II is coaxially aligned with the corresponding steel pipe pile, allowing the support blocks II to move horizontally and vertically with the upper top plate. The steel pipe piles are supported within the arc-shaped grooves II of the two support blocks II, and after detaching from the corresponding placement plate I or placement plate II, the steel pipe piles are moved out of the frame one by one. The horizontal leftward limit position of each lower bottom plate must ensure that the support block II can move horizontally to the left to directly below the leftmost steel pipe pile in the frame, and its rightward limit position must ensure that the support block II can move horizontally to the right out of the frame and move to a position close to the vertical pile device. The downward limit position of each upper top plate must ensure that the support block II can move horizontally with the lower bottom plate to directly below the corresponding steel pipe pile, and ensure that the arc-shaped groove II is coaxial with the steel pipe pile. The upward limit position of each upper top plate must ensure that the support block II can lift the steel pipe pile to detach it from the corresponding placement plate I or placement plate II.

[0012] Preferably, it also includes a placement plate III, a first slide rail, a first slider, a first fixing plate, a first motor, a first gear, a first rack, and a first limiting block; when the steel pipe pile is moved out of the frame to the right limit position, a placement plate III matching the lower cover is also horizontally arranged directly below the two corresponding lifting components. Both placement plates III are hollow cuboid structures with open upper surfaces, and their heights are both less than the vertical distance between the lower surface of the lower cover and the corresponding lifting lug II, ensuring that the two placement plates III are horizontally and longitudinally collinear; on the deck of the crane ship, a first slide rail is symmetrically arranged horizontally and longitudinally at intervals to the left and right of each placement plate III, and each first slide rail horizontally and longitudinally passes through the area directly below the corresponding placement plate III; on the lower surface of each placement plate III, a first slide rail is symmetrically arranged at intervals to the front and back of each first slide rail position, corresponding to the first slide rail. The matching first slider, and through the cooperation of the first slider and the corresponding first slide rail, the two placement plates III respectively move horizontally and longitudinally on the deck of the crane ship relative to the front and rear sides of the material handling mechanism, and ensure that the horizontal and longitudinal movement of the placement plate III does not interfere with the movement of the material handling mechanism; the first limiting block is also vertically provided on the deck of the crane ship at the front and rear ends of each first slide rail, and the horizontal and longitudinal movement of the corresponding placement plate III is limited by the first limiting block; the first rack is also horizontally and longitudinally parallel to each placement plate III at the position directly below the deck of the crane ship and between the two corresponding first slide rails, the length of each first rack is consistent with the length of the corresponding first slide rail, and the two are aligned, the tooth surface of each first rack is horizontally set to the right, and is fixedly installed on the corresponding position on the deck of the crane ship by stiffeners; A first fixing plate is horizontally fixed to the bottom of the outer side of each placement plate III in the front-rear direction. A first motor is vertically mounted on the upper surface of each first fixing plate relative to the corresponding first rack. Each first motor does not interfere with the movement of the steel pipe piles horizontally and longitudinally supported on the two placement plates III by the hoisting assembly. Its output end extends vertically downwards from the lower surface of the corresponding first fixing plate and is respectively connected to the corresponding first rack via a first gear. Thus, driven by the first motor, the two... The placement plates III move horizontally along their respective first slide rails. The opposing movement limit positions of the two placement plates III must be ensured. The two placement plates III are horizontally collinear with the two lower covers on the steel pipe pile. Thus, when the steel pipe pile moves out of the frame to the right limit position, it can be supported on the two placement plates III by the vertical up-and-down movement of the upper top plate. The opposing movement limit positions of the two placement plates III must be ensured. The two placement plates III can detach the two lifting assemblies from the corresponding steel pipe piles and will not interfere with the subsequent lifting of the steel pipe piles onto the vertical pile device.

[0013] Preferably, anti-deformation mechanisms are symmetrically arranged inside the frame relative to the front and rear sides of the steel pipe pile. Each anti-deformation mechanism includes a movable plate, a fixed seat, a third slide rail, a third slider, a third motor, a third gear, a third rack, a third limit block, a frame, a threaded rod, a guide rail, a fourth motor, a movable block, a rotating assembly, a sleeve, a first electric push rod, a pressure plate, and a locking block. Horizontally arranged movable plates are also symmetrically arranged inside the frame relative to the front and rear sides of the steel pipe pile. Several horizontally arranged third slide rails are also sequentially spaced along the left and right directions below the movable plates on the deck of the crane ship. The front and rear ends of each third slide rail horizontally and longitudinally pass through the area directly below the corresponding movable plate. A third slider matching the third slide rail is also spaced forward and backward on the lower surface of each movable plate relative to each third slide rail position. Through the cooperation of the third slider and the corresponding third slide rail, the two movable plates can move horizontally and longitudinally within the frame relative to the front and rear sides of the steel pipe pile. At the front and rear ends of each lower-level steel pipe pile, sleeves are coaxially fitted onto the outer sides of the corresponding hoisting components. The surface of each sleeve near the corresponding steel pipe pile is open, while its inner surface away from the steel pipe pile is in contact with the front and rear end faces of the corresponding steel pipe pile. The inner diameter of each sleeve is larger than the outer diameter of the steel pipe pile, and a frustum-shaped locking block matching the interior of the steel pipe pile is coaxially fixed to its inner surface away from the steel pipe pile. This locking block is then inserted into the corresponding steel pipe pile to ensure the stability of the steel pipe pile when it rotates around its own axis using the anti-deformation mechanism. Furthermore, along the circumferential direction of the outer circumference of each sleeve, there are sequentially... Several first electric push rods are arranged radially along the sleeve at intervals. The pushing end of each electric push rod extends vertically into the interior of the sleeve and is screwed and fixed to the corresponding pressure plate. A second rubber pad is also fixedly attached to one side of each pressure plate near the corresponding locking block. Driven by the first electric push rods, the second rubber pads on the pressure plate abut against the corresponding position on the surface of the steel pipe pile, so that the sleeve is connected to the corresponding steel pipe pile. The pushing end of each first electric push rod must ensure that the pressure plate is in contact with the corresponding position on the surface of the steel pipe pile when it extends to its limit position, and its retracted limit position must ensure that the pressure plate is disengaged from the surface of the corresponding steel pipe pile. On the upper surface of each movable plate, a hollow cuboid frame is vertically provided relative to each sleeve position. The surface of each frame near the steel pipe pile is open, and each frame is fixedly installed on the upper surface of the corresponding movable plate by a fixing seat, ensuring that adjacent frames on the same movable plate are arranged in a straight line with left and right spacing. Two threaded rods are vertically symmetrically arranged at left and right intervals in the middle of the interior of each frame. The lower end of each threaded rod is rotatably connected to the inner bottom surface of the corresponding frame about its own axis, and its upper end extends vertically upward from the upper surface of the corresponding frame, and is linked to the output end of the corresponding fourth motor. The two fourth motors on the same frame operate synchronously, and are vertically symmetrically arranged on the front and rear sides of each threaded rod within the interior of each frame. The frame is equipped with guide rails, and the upper and lower ends of each guide rail are fixedly connected to the inner top and inner bottom surfaces of the frame, respectively. Each threaded rod is also fitted with a movable block at intervals, and the four movable blocks within the same frame are arranged in a rectangular symmetrical configuration. Each movable block is screwed to the corresponding threaded rod and vertically slidably connected to the corresponding two guide rails. The four movable blocks within the same frame extend vertically from the steel pipe pile side of the corresponding frame and are connected to the outer surface of the corresponding sleeve away from the steel pipe pile via a rotating assembly. Driven by a fourth motor, the sleeve moves vertically up and down with the movable blocks, ensuring that the sleeve is coaxial with the uppermost corresponding steel pipe pile when at its upper limit position and with the lowermost corresponding steel pipe pile when at its lower limit position. On the deck of the crane vessel, a third rack is horizontally and longitudinally arranged directly below each movable plate and between each pair of adjacent frames. The length of each third rack is consistent with the length of the corresponding third slide rail, and the two are aligned and do not interfere with each other. The teeth of each third rack are horizontally arranged facing the right and are fixedly mounted on the deck of the crane vessel by stiffeners. A third motor is vertically arranged on the upper surface of each movable plate relative to each third rack. The operation of each third motor on the same movable plate is synchronized, and they are spaced apart between adjacent fixed seats. The output ends of the three motors extend vertically downwards from the lower surface of the corresponding moving plates, and are respectively connected to the corresponding third rack via a third gear. Driven by the third motor, the two moving plates move horizontally and longitudinally within the frame relative to the front and rear sides of the steel pipe pile through the meshing of the third gear and the corresponding third rack. The horizontal movement limit position of the two moving plates toward the steel pipe pile must ensure that the sleeve can be coaxially fitted onto both ends of the corresponding steel pipe pile, and the horizontal movement limit position away from the steel pipe pile must ensure that the sleeve can be disengaged from both ends of the corresponding steel pipe pile, without interfering with the action of the material handling mechanism to remove the steel pipe pile from the frame.

[0014] Preferably, each of the rotating components includes a housing, a gear shaft, a fifth motor, a main bevel gear, a driven bevel gear, and a roller assembly; a hollow cylindrical housing is coaxially disposed between each sleeve and the corresponding frame, and the outer surface of each housing away from the corresponding sleeve is fixedly connected to the four corresponding moving blocks, thereby moving vertically up and down with the moving blocks and moving horizontally longitudinally with the moving plate; a gear shaft is horizontally longitudinally disposed in the middle of the interior of each housing, and each gear shaft is rotatably connected to the corresponding housing about its own axis, and its end near the sleeve extends horizontally longitudinally out of the corresponding housing, and is coaxially fixedly connected to the outer surface of the corresponding sleeve away from the steel pipe pile; in each gear shaft A driven bevel gear is coaxially and fixedly fitted inside the corresponding housing, and each housing does not interfere with the rotation of the driven bevel gear with the corresponding gear shaft. Inside each housing, a fifth motor is vertically installed directly above the driven bevel gear, and the two fifth motors acting on the same steel pipe pile operate synchronously. The fixed end of each fifth motor is screwed to the inner top surface of the corresponding housing, and its output end is vertically downward toward the corresponding driven bevel gear. They are respectively connected to the corresponding driven bevel gear through the meshing of the main bevel gear and the corresponding driven bevel gear. Under the drive of the fifth motor, through the meshing of the main bevel gear and the corresponding driven bevel gear, the sleeve rotates horizontally around its own axis with the gear shaft, and drives the corresponding steel pipe pile to rotate around its own axis. Several sets of rollers are connected to the outer surface of each box body near the steel pipe pile, and these roller sets are all coaxially arranged with the corresponding box body and are not interfered with by the corresponding gear shaft. Each set of rollers is conical, with one end near the corresponding gear shaft being the small end and the other end being the large end, so as to accommodate a smaller linear velocity near the gear shaft when the box body rotates.

[0015] The present invention discloses a handling process for a steel pipe pile auxiliary handling system based on a crane vessel, the innovation of which lies in including the following steps: (1) During the storage and transportation of steel pipe piles (1.1) First, by synchronously unwinding the winch, the placement plate II is lowered to the lower limit position. Then, the steel pipe piles are horizontally and longitudinally supported on the support block II of the material taking mechanism. Then, by synchronously moving the material taking mechanism horizontally and vertically, the steel pipe piles are horizontally and longitudinally supported one by one in the corresponding placement slot II of the placement plate II. (1.2) Then, by the synchronous winding of the winch, the placement plate II is raised to the upper limit position, and then by the synchronous horizontal and vertical movement of the material taking mechanism, the steel pipe piles are horizontally and longitudinally supported one by one in the corresponding placement slot I of the placement plate I. (1.3) Then, by synchronously unwinding the winch, the placement plate II is lowered and supported on the corresponding upper cover of the lower layer of steel pipe piles. At this time, the storage and transportation of steel pipe piles can be carried out. (1.4) Every once in a while, driven by the third motor, the two moving plates move towards each other to their limit positions, and each sleeve is coaxially fitted onto the two ends of the corresponding steel pipe pile in the lower layer. Then the pushing end of the first electric push rod extends, so that the pressure plate is pressed against the corresponding position of the surface of the steel pipe pile through the second rubber pad. At this time, driven by the fifth motor, the gear shaft rotates around its own axis, which can drive the corresponding steel pipe pile to rotate, thereby preventing the deformation of the steel pipe pile in the lower layer. (1.5) Then the pushing end of the first electric push rod retracts, causing the pressure plate to detach from the surface of the corresponding steel pipe pile; then, driven by the third motor, the two moving plates move back to back to the limit position, and the sleeve detaches from the corresponding steel pipe pile; then, driven by the fourth motor, the sleeve rises with the moving block to the upper limit position, and then, driven by the third motor, the two moving plates move towards each other to the limit position, and each sleeve is coaxially sleeved at both ends of the corresponding upper steel pipe pile. Then, repeating the above steps can prevent deformation of the upper steel pipe pile. (2) When it is necessary to move the steel pipe piles out of the frame and onto the vertical pile device (2.1) First, the pushing end of the first electric push rod retracts, causing the pressure plate to detach from the surface of the corresponding steel pipe pile; then, driven by the third motor, the two moving plates move back to back to their limit positions, causing the sleeve to detach from the corresponding steel pipe pile. (2.2) Then, by synchronous winding of the winch, the placement plate II is raised and detached from the corresponding hoisting component of the lower layer of steel pipe pile; (2.3) Then, driven by the second motor, the support block II moves horizontally to the left along with the bottom plate to the position inside the frame relative to the rightmost steel pipe pile. Then, by the rise of the top plate, the support block II lifts the rightmost steel pipe pile of the lower layer and removes it from the placement plate I. Then, driven by the second motor, the support block II moves horizontally to the right along with the bottom plate to the right limit position and moves the rightmost steel pipe pile of the lower layer out of the frame. (2.4) Then, driven by the first motor, the two placement plates III move towards each other to their limit positions. Then, by the descent of the top plate, the steel pipe pile is supported on the two placement plates III by the hoisting assembly. At this time, the pushing end of the second electric push rod retracts, causing the clamping plate to detach from the corresponding steel pipe pile. Then, driven by the first motor, the two placement plates III move away from each other to their limit positions, so that the two hoisting assemblies can detach from the corresponding steel pipe piles respectively. (2.5) Then, in a low-altitude state, the lifting device is tied to the steel pipe pile, and the steel pipe pile can be lifted onto the vertical pile device by the crane of the crane ship in coordination with the lifting device. (2.6) Then repeat the above steps to move the lower layer steel pipe piles out of the frame one by one and hoist them onto the vertical pile device; then, by synchronously unwinding the winch, the placement plate II is lowered to the lower limit position. At this time, repeat the above steps to move the upper layer steel pipe piles out of the frame one by one and hoist them onto the vertical pile device.

[0016] The beneficial effects of this invention are: (1) By using the hoisting components, placement plate I, placement plate II, wire rope, winch, material handling mechanism and crane in combination, the present invention can not only stack several steel pipe piles in an orderly manner in the frame for overall transportation, saving space, but also facilitate the removal of steel pipe piles one by one from the frame and hoisting them onto the vertical pile device in a low-altitude operation state. This process is time-saving and labor-saving, and avoids high-altitude operation, with high safety. (2) By setting up a hoisting assembly, the present invention not only facilitates the hoisting of steel pipe piles, but also works with placement plate I and placement plate II to ensure that the steel pipe piles are stacked in an orderly manner within the frame, thereby saving space. (3) By using the placement plate III, the first slide rail, the first slider, the first fixing plate, the first motor, the first gear, the first rack and the first limiting block in combination, the present invention can automatically detach the hoisting component from the corresponding steel pipe pile after the steel pipe pile is removed from the frame, so as to facilitate the hoisting tool to be tied to the corresponding steel pipe pile in the low-altitude operation state, and then the steel pipe pile is hoisted to the vertical pile device by the crane for subsequent turning operation. This process saves time and effort and improves work efficiency. (4) By setting up an anti-deformation mechanism, the present invention can drive the corresponding steel pipe piles to rotate along their own axis one by one. This process not only saves time and effort, but also avoids the deformation of the steel pipe piles due to long placement time. Attached Figure Description

Detailed Implementation

[0035] The technical solution of the present invention will be clearly and completely described below through specific embodiments.

[0036] This invention discloses an auxiliary handling system for steel pipe piles based on a crane vessel, comprising a frame 1, a placement plate I 2, a placement plate II 4, a hoisting assembly 5, a lifting mechanism, and a material handling mechanism 7; as shown... Figures 1-16As shown, the crane vessel is arranged along the forward and backward direction, and a hollow rectangular frame 1 is horizontally and longitudinally arranged on its deck on one side relative to the vertical pile device 19. On the deck of the crane vessel, horizontally arranged placement plates I2 are symmetrically spaced forward and backward relative to the interior of the frame 1. Inside the frame 1, horizontally aligned placement plates II4 are positioned directly above each placement plate I2. The two placement plates II4 are synchronously raised and lowered within the frame 1 in the area directly above the placement plates I2 via a lifting mechanism. Parallel horizontal alignment is also provided on the two placement plates I2 and the two placement plates II4. Several horizontally and longitudinally arranged steel pipe piles 3 are arranged, and each steel pipe pile 3 is symmetrically fitted with lifting components 5 at both ends, so that each steel pipe pile 3 is supported on two corresponding placement plates I2 or two placement plates II4 by the corresponding lifting components 5. On the deck of the crane ship, there are also material picking mechanisms 7 symmetrically arranged at intervals between the frame 1 and the vertical pile device 19. Through the synchronous horizontal and vertical movement of the two material picking mechanisms 7, the steel pipe piles 3 are moved out of the frame 1 one by one, and then lifted one by one onto the vertical pile device 19 by the crane 20 and lifting gear 21 on the crane ship. The vertical pile device 19 of this invention is a conventional device used to turn the steel pipe piles 3 over. This is prior art. What this application aims to protect is how the steel pipe piles 3 are stacked as a whole on the crane ship, and how the stacked steel pipe piles 3 are lifted one by one onto the vertical pile device 19 in a low-altitude operation state. Therefore, the structure of the vertical pile device 19 will not be described in detail here.

[0037] The frame 1 of this invention includes a vertical tube 101, a horizontal tube I 102, a horizontal tube II 103, a horizontal reinforcing tube 104, a vertical reinforcing tube 105, a longitudinal reinforcing tube 107, and a transverse reinforcing tube 106; as shown Figure 1 , Figure 3As shown, two horizontal pipes II 103 are arranged symmetrically in a horizontal direction with a gap between them. Horizontal pipes I 102 are also welded horizontally and longitudinally between the two horizontal pipes II 103 at their ends, forming a rectangular structure arranged horizontally and longitudinally. Vertical pipes 101 are also vertically aligned at both ends of the lower surface of each horizontal pipe II 103, and the four vertical pipes 101 are arranged symmetrically in a rectangle. The frame 1 is fixed to the deck of the crane vessel through the vertical pipes 101. Horizontal reinforcing pipes 104 are also welded horizontally or longitudinally between each pair of adjacent vertical pipes 101 at a position slightly above the middle. The distance between each horizontal reinforcing pipe 104 and the deck of the crane vessel must be greater than the height of the lifting assembly 5, and must ensure that it does not interfere with the action of the material handling mechanism 7 in moving the steel pipe pile 3 out of the frame 1. The distance between each horizontal reinforcing pipe 104 and the crane vessel deck must be greater than the height of the lifting assembly 5, and must ensure that it does not interfere with the action of the material handling mechanism 7 in moving the steel pipe pile 3 out of the frame 1. Vertical reinforcing tubes 105 are welded vertically in sequence at intervals along the length between horizontal tubes I 102 or horizontal tubes II 103, and the stability of the frame 1 is ensured by the cooperation of horizontal reinforcing tubes 104 and vertical reinforcing tubes 105. Several horizontally arranged transverse reinforcing tubes 106 are welded horizontally in sequence at intervals along the length between two horizontal tubes I 102 and in the area between two horizontal tubes II 103. Several horizontally arranged longitudinal reinforcing tubes 107 are welded horizontally in sequence at intervals along the length between each adjacent transverse reinforcing tube 106, between the foremost transverse reinforcing tube 106 and the foremost horizontal tube II 103, and between the last transverse reinforcing tube 106 and the last horizontal tube II 103. The stability of the frame 1 is ensured by the cooperation of transverse reinforcing tubes 106 and longitudinal reinforcing tubes 107.

[0038] Each lifting assembly 5 of this invention includes an upper cover 51, a lower cover 52, a connecting plate 53, a lifting lug II 54, a support block I 55, a rubber roller 56, a second fixing plate 57, a reinforcing plate, a second electric push rod 58, a clamping plate 59, and a first rubber pad; as shown Figures 1-16As shown, at the front and rear ends of each steel pipe pile 3, directly below its stress point, a lower cover 52 is provided. Each lower cover 52 is a U-shaped structure that matches the steel pipe pile 3, with its open end facing upwards, and its opening groove is arranged horizontally. A support block I 55 is horizontally provided in the middle of the inner bottom surface of each lower cover 52, and an arc-shaped groove I matching the steel pipe pile 3 is embedded in the upper surface of each support block I 55. Each arc-shaped groove I is coaxially arranged with the corresponding steel pipe pile 3, and several horizontally arranged rubber rollers 56 are arranged at intervals along the arc direction in each arc-shaped groove I. Each rubber roller 56 is rotatably connected to the corresponding support block I 55 around its own axis. Each steel pipe pile 3 passes horizontally through the corresponding two lower covers 52, and its stress point is supported in the arc-shaped groove I of the corresponding support block I 55. Thus, the lower cover 52, support block I 55 and rubber roller 56 cooperate to support the corresponding steel pipe pile 3. like Figures 1-16 As shown, an upper cover 51 is horizontally aligned with each lower cover 52 on the upper surface of each steel pipe pile 3. Each upper cover 51 is a U-shaped structure that matches the steel pipe pile 3, and its bottom surface size is consistent with that of each lower cover 52. The opening slots of each upper cover 51 are arranged along the horizontal longitudinal direction, and their opening ends are all set downwards. Adjacent upper cover 51 and lower cover 52 are screwed together by connecting plates 53 to form a hollow cuboid structure that is open at the front and back. After the steel pipe pile 3 passes through the corresponding hollow cuboid structure in a horizontal longitudinal direction, it is supported on the rubber roller 56 in the corresponding arc-shaped groove I. Lifting lugs II 54 are vertically welded on the front and rear sides and near the bottom of each upper cover 51 and lower cover 52. The corresponding upper cover 51 or lower cover 52 is lifted by the lifting lugs II 54, and it is ensured that the lifting lugs II 54 do not interfere with the movement of the steel pipe pile 3 being supported horizontally in the longitudinal direction by the lifting assembly 5 on the corresponding placement plate I 2 or placement plate II 4.

[0039] like Figures 1-16As shown, the height of each upper cover 51 is greater than the height of the corresponding lower cover 52, and it must be ensured that the position of the connecting plate 53 does not interfere with the corresponding lifting lug II 54; a second fixing plate 57 is symmetrically arranged horizontally and vertically at the lower center of the left and right inner sides of each upper cover 51, and each pair of adjacent second fixing plates 57 are spaced apart on the left and right sides of the corresponding steel pipe pile 3; a reinforcing plate is vertically arranged between the lower surface of each second fixing plate 57 and the corresponding inner side of the upper cover 51, and the second fixing plate 57 is fixed and reinforced by the reinforcing plate; a second electric push rod 58 is horizontally arranged on the upper surface of each second fixing plate 57, and the tail of each second electric push rod 58 is fixedly installed by a stiffening plate. The upper surface of the corresponding second fixing plate 57 is provided with its pushing end facing the center direction of the corresponding steel pipe pile 3, and is screwed and fixed to the corresponding clamping plate 59 arranged vertically. A first rubber pad is also fixedly attached to one side of each clamping plate 59 near the steel pipe pile 3. Under the drive of the corresponding second electric push rod 58, the first rubber pad on each clamping plate 59 is in close contact with the corresponding position on the surface of the corresponding steel pipe pile 3, thereby limiting the left and right direction of the corresponding steel pipe pile 3. The pushing end of each second electric push rod 58 must extend to the limit position to ensure that the clamping plate 59 can contact the surface of the corresponding steel pipe pile 3, and its retraction limit position must ensure that the clamping plate 59 is disengaged from the corresponding steel pipe pile 3, and does not interfere with the rotation of the steel pipe pile 3 around its own axis.

[0040] like Figures 1-16 As shown, the front placement plate I2 is positioned directly below all the hoisting components 5 arranged in the same horizontal direction relative to the front side, and the rear placement plate I2 is positioned directly below all the hoisting components 5 arranged in the same horizontal direction relative to the rear side. The length and width of each placement plate I2 match the length and width of the corresponding placement plate II4, and they are all spaced apart within the frame 1, ensuring that the frame 1 does not interfere with the vertical up-and-down movement of all the upper steel pipe piles 3 with the placement plate II4. On the upper surface of each placement plate I2, a placement groove I that matches the bottom surface of the lower cover 52 is vertically embedded at the position of each hoisting component 5 in the lower layer. The opening depth of each placement groove I is less than the vertical distance between the lower surface of the lower cover 52 and its corresponding lifting lug II 54. Thus, through the cooperation of the lower cover 52 and the corresponding placement groove I, each steel pipe pile 3 placed on the placement plate I2 is horizontally positioned, ensuring that all the steel pipe piles 3 in the lower layer are horizontally and longitudinally arranged in parallel and aligned in the same horizontal plane. like Figures 1-16As shown, each of the upper surfaces of the placement plate II4 is vertically embedded with a placement groove II that matches the bottom surface of the lower cover 52 at the position of each hoisting component 5 on the upper layer. The depth of each placement groove II is less than the vertical distance between the lower surface of the lower cover 52 and its corresponding hoisting lug II 54. Thus, through the cooperation between the lower cover 52 and the corresponding placement groove II, each steel pipe pile 3 placed on the placement plate II4 is horizontally positioned, and all steel pipe piles 3 on the upper layer are horizontally and longitudinally arranged in parallel and aligned on the same horizontal plane. The lifting mechanism of this invention includes a winch 10, a wire rope 9, and a lifting lug I 8; as shown Figures 1-16 As shown, lifting lugs I8 are welded vertically and symmetrically at intervals on the left and right sides of each placement plate II4. Furthermore, winches 10 are installed on the inner top surface of the frame 1, positioned on the left and right sides of each placement plate II4, ensuring that each winch 10 is positioned directly above each pair of adjacent lifting lugs I8. The four winches 10 operate synchronously, and each winch 10 is equipped with two horizontally coaxially arranged drums. Steel wire ropes 9 are wound around the two drums of each winch 10, thereby connecting one end of each set of steel wire ropes 9 on each winch 10 to the corresponding two lifting lugs I8. With the connection of 8, the synchronous winding and unwinding actions of the four winches 10 enable the two placement plates II4 to move vertically up and down synchronously, and all the steel pipe piles 3 on the upper layer to rise and fall synchronously with the placement plates II4. The lowering limit positions of the two placement plates II4 must ensure that the placement plates II4 can descend to a position close to the corresponding placement plate I2, and that the steel pipe piles 3 on the placement plates II4 can be removed from the frame 1 by the material handling mechanism 7. The rising limit positions of the two placement plates II4 must ensure that the placement plates II4 detach from the lower-level hoisting assembly 5, and that the material handling mechanism 7 does not interfere with the removal of the steel pipe piles 3 on the placement plates I2 from the frame 1. The winches 10 equipped with two drums in this invention are existing conventional equipment, and the synchronous winding and unwinding actions of the winches 10 can be controlled by a controller. This is prior art, therefore, the structure and working principle of the winches 10 will not be described in detail here.

[0041] Each material handling mechanism 7 of this invention includes a lower base plate 701, a lifting assembly 702, an upper top plate 703, a support block II 704, a second slide rail 705, a second slider 706, a second motor 707, a second gear 708, a second rack 709, and a second limiting block 710; as shown Figures 1-16As shown, horizontally arranged lower base plates 701 are symmetrically arranged at intervals between the frame 1 and the vertical pile device 19, relative to the area between the two placement plates I2. Furthermore, horizontally arranged second slide rails 705 are symmetrically arranged at intervals below each lower base plate 701 on the deck of the crane vessel. The right end of each second slide rail 705 extends to the right near the vertical pile device 19, and its left end extends to the left into the interior of the frame 1, and is horizontally aligned with the left side of each placement plate I2. The following configuration is provided: On the lower surface of each lower base plate 701, a second slider 706 is symmetrically provided at left and right intervals relative to each second slide rail 705, and the lower base plate 701 can move horizontally through the cooperation of the second slide rail 705 and the second slider 706; On the deck of the crane ship, a second limiting block 710 is fixed at the left and right ends of each second slide rail 705, and the horizontal movement of the lower base plate 701 is limited by the second limiting block 710. like Figures 1-16 As shown, on the deck of the crane vessel, a second rack 709 is horizontally arranged below each lower base plate 701 and between two corresponding second slide rails 705. The length of each second rack 709 is the same as the length of each second slide rail 705, and the two are aligned. The teeth of each second rack 709 are horizontally arranged facing forward and are fixed to the deck of the crane vessel by stiffeners. A second motor 707 is vertically arranged on the upper surface of each lower base plate 701 relative to the position of the corresponding second rack 709. Each second motor 707 is positioned at the corresponding position. The upper surface of the lower base plate 701 is located at the right end, and the two second motors 707 operate synchronously. The output end of each second motor 707 extends vertically downward from the lower surface of the corresponding lower base plate 701, and is respectively connected to the corresponding second rack 709 through the meshing of the second gear 708. Thus, driven by the second motor 707, the two lower base plates 701 move horizontally synchronously through the meshing of the second gear 708 and the corresponding second rack 709. The present invention can control the synchronous operation of the second motors 707 through a controller, which is prior art, so its principle will not be described in detail here.

[0042] like Figures 1-16As shown, a matching upper top plate 703 is horizontally aligned and aligned directly above each lower bottom plate 701. A lifting assembly 702 is symmetrically positioned between each upper top plate 703 and its corresponding lower bottom plate 701, spaced apart from the left side of the second motor 707. The four lifting assemblies 702 operate synchronously, enabling the two upper top plates 703 to move vertically up and down synchronously. A support block II 704 is horizontally positioned in the middle of the upper surface of each upper top plate 703. The two support blocks II 704 are symmetrically arranged, and an arc-shaped groove II matching the steel pipe pile 3 is embedded in the upper surface of each support block II 704. Each arc-shaped groove II is coaxially aligned with the corresponding steel pipe pile 3, allowing the support blocks II 704 to move horizontally and vertically with the upper top plate 703. The steel pipe pile 3 is supported in the arc-shaped grooves II of the two support blocks II 704, and after it is separated from the corresponding placement plate I 2 or placement plate II 4, the steel pipe pile 3 is moved out of the frame 1 one by one; the horizontal left limit position of each lower bottom plate 701 must ensure that the support block II 704 can move horizontally to the left to be directly below the leftmost steel pipe pile 3 in the frame 1, and its right limit position must ensure that the support block II 704 can move horizontally to the right out of the frame 1 and move to a position close to the vertical pile device 19; the downward limit position of each upper top plate 703 must ensure that the support block II 704 can move horizontally with the lower bottom plate 701 to be directly below the corresponding steel pipe pile 3, and ensure that the arc-shaped groove II is coaxial with the steel pipe pile 3; the upward limit position of each upper top plate 703 must ensure that the support block II 704 can lift the steel pipe pile 3 to separate it from the corresponding placement plate I 2 or placement plate II 4. The lifting component 702 of this invention can be an existing lifting platform, which is a conventional device. Therefore, the structure and working principle of the lifting component 702 will not be described in detail here.

[0043] like Figures 1-16As shown, when the steel pipe pile 3 is moved out of the frame 1 to the right limit position, two horizontal placement plates III11 matching the lower cover 52 are respectively provided directly below the two corresponding lifting components 5. Both placement plates III11 are hollow cuboid structures with open upper surfaces, and their heights are both less than the vertical distance between the lower surface of the lower cover 52 and its corresponding lifting lug II 54, ensuring that the two placement plates III11 are horizontally and longitudinally aligned. On the deck of the crane ship, first slide rails 12 are symmetrically arranged horizontally and longitudinally at intervals to the left and right of each placement plate III11, and each first slide rail 12 horizontally and longitudinally passes through the area directly below the corresponding placement plate III11. On the lower surface of each placement plate III11, first sliders 13 matching the first slide rails 12 are symmetrically arranged front and back at intervals to the front and rear of each first slide rail 12, and the first sliders 13 and the corresponding first slide rails are connected by the first slide rails 12. With the cooperation of 12, the two placement plates Ⅲ11 respectively move horizontally and longitudinally on the deck of the crane ship relative to the front and rear sides of the material handling mechanism 7, and ensure that the horizontal and longitudinal movement of the placement plates Ⅲ11 and the movement of the material handling mechanism 7 do not interfere with each other; on the deck of the crane ship, at the front and rear ends of each first slide rail 12, a first limiting block 18 is also vertically provided, and the horizontal and longitudinal movement of the corresponding placement plate Ⅲ11 is limited by the first limiting block 18; on the deck of the crane ship, at the position directly below each placement plate Ⅲ11 and between the corresponding two first slide rails 12, a first rack 17 is also horizontally and longitudinally parallel, the length of each first rack 17 is consistent with the length of the corresponding first slide rail 12, and the two are aligned, the tooth surface of each first rack 17 is horizontally set to the right, and is fixedly installed on the corresponding position on the deck of the crane ship by stiffeners. like Figures 1-16As shown, a first fixing plate 14 is horizontally fixed to the bottom of each placement plate Ⅲ11 on its outer side in the front-rear direction. A first motor 15 is vertically mounted on the upper surface of each first fixing plate 14 relative to the corresponding first rack 17. Each first motor 15 does not interfere with the movement of the steel pipe pile 3, which is horizontally and longitudinally supported on the two placement plates Ⅲ11 by the hoisting assembly 5. Its output end extends vertically downward from the lower surface of the corresponding first fixing plate 14 and is connected to the corresponding first rack 17 via a first gear 16. Thus, driven by the first motor 15, the two... Placement plates III11 move horizontally along the corresponding first slide rail 12. The opposing movement limit positions of the two placement plates III11 must be ensured. The two placement plates III11 are horizontally aligned with the two lower covers 52 on the steel pipe pile 3. When the steel pipe pile 3 moves out of the frame 1 to the right limit position, it can be supported on the two placement plates III11 by the vertical up and down movement of the upper top plate 703. The opposing movement limit positions of the two placement plates III11 must be ensured. The two placement plates III11 can detach the two lifting assemblies 5 from the corresponding steel pipe pile 3 respectively, and will not interfere with the subsequent lifting of the steel pipe pile 3 onto the vertical pile device 19.

[0044] The present invention further includes symmetrical anti-deformation mechanisms 6 on the front and rear sides of the frame 1 relative to the steel pipe pile 3. Each anti-deformation mechanism 6 includes a movable plate 601, a fixed seat 602, a third slide rail 603, a third slider 604, a third motor 605, a third gear 606, a third rack 607, a third limiting block 608, a frame 609, a threaded rod 610, a guide rail 611, a fourth motor 612, a movable block 613, a rotating assembly, a sleeve 620, a first electric push rod 621, a pressure plate 622, and a locking block 623. Figures 1-16 As shown, inside the frame 1, horizontally arranged movable plates 601 are symmetrically arranged on the front and rear sides of the steel pipe pile 3. On the deck of the crane ship, several horizontally arranged third slide rails 603 are arranged in a left-right direction and aligned in sequence below the movable plates 601. The front and rear ends of each third slide rail 603 pass horizontally through the area directly below the corresponding movable plate 601. On the lower surface of each movable plate 601, third sliders 604 matching the third slide rails 603 are arranged at intervals in front and behind each third slide rail 603. Through the cooperation of the third sliders 604 and the corresponding third slide rails 603, the two movable plates 601 can move horizontally in the area inside the frame 1 relative to the front and rear sides of the steel pipe pile 3. like Figures 1-16As shown, at the front and rear ends of each steel pipe pile 3 in the lower layer, sleeves 620 are coaxially sleeved relative to the outer side of the corresponding hoisting assembly 5. The surface of each sleeve 620 near the corresponding steel pipe pile 3 is open, and its inner surface away from the steel pipe pile 3 is respectively in contact with the front and rear end faces of the corresponding steel pipe pile 3. The inner diameter of each sleeve 620 is larger than the outer diameter of the steel pipe pile 3, and a frustum-shaped locking block 623 matching the inside of the steel pipe pile 3 is coaxially fixed on its inner surface away from the steel pipe pile 3. The locking block 623 is then inserted into the corresponding steel pipe pile 3 to ensure the stability of the steel pipe pile 3 when it rotates around its own axis through the anti-deformation mechanism 6. On the outer circumference of each sleeve 620, there are also sleeves spaced at intervals along its circumference. Several first electric push rods 621 are arranged radially along the sleeve 620. The pushing end of each electric push rod extends vertically into the interior of the sleeve 620 and is screwed to the corresponding pressure plate 622. A second rubber pad is also attached to and fixed on one side of each pressure plate 622 near the corresponding locking block 623. Driven by the first electric push rods 621, the second rubber pads on the pressure plate 622 abut against the corresponding position on the surface of the steel pipe pile 3, so that the sleeve 620 is connected to the corresponding steel pipe pile 3. The pushing end of each first electric push rod 621 must ensure that the pressure plate 622 contacts the corresponding position on the surface of the steel pipe pile 3 when it extends to its limit position, and its retracted limit position must ensure that the pressure plate 622 is disengaged from the surface of the corresponding steel pipe pile 3. like Figures 1-16As shown, a hollow rectangular frame 609 is vertically provided on the upper surface of each movable plate 601 relative to each sleeve 620. The surface of each frame 609 near the steel pipe pile 3 is open, and each frame 609 is fixedly installed on the upper surface of the corresponding movable plate 601 via a fixing seat 602, ensuring that adjacent frames 609 on the same movable plate 601 are arranged in a straight line with left and right intervals. Two threaded rods 610 are vertically symmetrically arranged at left and right intervals in the middle of the interior of each frame 609. The lower end of each threaded rod 610 is rotatably connected to the inner bottom surface of the corresponding frame 609 around its own axis, and its upper end extends vertically upwards from the upper surface of the corresponding frame 609, and is linked to the output end of the corresponding fourth motor 612. The two fourth motors 612 on the same frame 609 operate synchronously. Furthermore, guide rails 611 are vertically spaced and symmetrically arranged on the front and rear sides of each threaded rod 610 inside each frame 609, and the upper and lower ends of each guide rail 611 are respectively connected to the frame... The inner top and bottom surfaces of 609 are fixedly connected at corresponding positions; each threaded rod 610 is also fitted with a movable block 613 at intervals, and the four movable blocks 613 in the same frame 609 are arranged in a rectangular symmetrical manner. Each movable block 613 is screwed to the corresponding threaded rod 610 and is vertically slidably connected to the two corresponding guide rails 611; the surface of the four movable blocks 613 in the same frame 609 near the steel pipe pile 3 extends vertically out of the corresponding frame 609, and is respectively rotated The component is connected to the outer surface of the corresponding sleeve 620 away from the steel pipe pile 3. Then, driven by the fourth motor 612, the sleeve 620 moves vertically up and down with the moving block 613. It is necessary to ensure that the sleeve 620 is coaxial with the corresponding upper layer steel pipe pile 3 when it is in the upper limit position, and it is necessary to ensure that the sleeve 620 is coaxial with the corresponding lower layer steel pipe pile 3 when it is in the lower limit position. The present invention can control the operation of the fourth motor 612 to synchronize through the controller. This is the prior art, so its working principle will not be described in detail here. like Figures 1-16As shown, on the deck of the crane vessel, a third rack 607 is horizontally and longitudinally arranged directly below each movable plate 601 and between each pair of adjacent frames 609. The length of each third rack 607 is consistent with the length of the corresponding third slide rail 603, and the two are aligned and do not interfere with each other. The teeth of each third rack 607 are horizontally arranged facing the right and are fixedly installed on the deck of the crane vessel by stiffeners. A third motor 605 is vertically arranged on the upper surface of each movable plate 601 relative to each third rack 607. The operation of each third motor 605 on the same movable plate 601 is synchronized, and they are spaced apart between adjacent fixed seats 602. The output ends of the 05 motors extend vertically downwards from the lower surface of the corresponding moving plates 601, and are respectively connected to the corresponding third racks 607 via third gears 606. Driven by the third motor 605, the meshing of the third gears 606 and the corresponding third racks 607 causes the two moving plates 601 to move horizontally longitudinally within the frame 1 relative to the front and rear sides of the steel pipe pile 3. The horizontal movement limits of the two moving plates 601 towards the steel pipe pile 3 must ensure that the sleeves 620 can be coaxially fitted onto both ends of the corresponding steel pipe pile 3, and their horizontal movement limits away from the steel pipe pile 3 must ensure that the sleeves 620 can disengage from both ends of the corresponding steel pipe pile 3, without interfering with the action of the material handling mechanism 7 in moving the steel pipe pile 3 out of the frame 1. This invention can synchronize the action of the third motor 605 through a controller; this is prior art, and its working principle will not be described in detail here.

[0045] Each rotating component of this invention includes a housing 614, a gear shaft 615, a fifth motor 616, a main bevel gear 617, a driven bevel gear 618, and a roller assembly 619; as shown Figures 1-16As shown, a hollow cylindrical box 614 is coaxially provided between each sleeve 620 and the corresponding frame 609. The outer surface of each box 614 away from the corresponding sleeve 620 is fixedly connected to four corresponding moving blocks 613, and thus moves vertically up and down with the moving blocks 613 and horizontally longitudinally with the moving plate 601. A gear shaft 615 is horizontally longitudinally provided in the middle of the interior of each box 614. Each gear shaft 615 is rotatably connected to the corresponding box 614 around its own axis, and its end near the sleeve 620 extends horizontally longitudinally out of the corresponding box 614, and is coaxially fixedly connected to the outer surface of the corresponding sleeve 620 away from the steel pipe pile 3. A driven bevel gear 618 is coaxially sleeved and fixed on each gear shaft 615 relative to the interior of the corresponding box 614, and each box 614 moves with the driven bevel gear 618. The rotation of the gear shaft 615 does not cause interference. Inside each housing 614, a fifth motor 616 is vertically arranged directly above the bevel gear 618. The two fifth motors 616 acting on the same steel pipe pile 3 operate synchronously. The fixed end of each fifth motor 616 is screwed to the inner top surface of the corresponding housing 614, and its output end is vertically downward towards the corresponding bevel gear 618. It is connected to the corresponding bevel gear 618 through the main bevel gear 617. Driven by the fifth motor 616, through the meshing of the main bevel gear 617 and the corresponding bevel gear 618, the sleeve 620 rotates horizontally around its own axis with the gear shaft 615, and drives the corresponding steel pipe pile 3 to rotate around its own axis. The present invention can control the operation of the fifth motor 616 to synchronize the operation of the fifth motor 616. This is the prior art, so its working principle will not be described in detail here. like Figures 1-16 As shown, several sets of rollers 619 are connected to the outer surface of each housing 614 near the steel pipe pile 3, and are in contact with the corresponding sleeve 620. The sets of rollers 619 are all coaxially arranged with the corresponding housing 614 and are respectively arranged without interfering with the corresponding gear shaft 615. Each set of rollers 619 is conical, and the end of each set of rollers near the corresponding gear shaft 615 is a small end and the other end is a large end, so as to accommodate a smaller linear velocity near the gear shaft 615 when the housing 614 rotates.

[0046] The motors, electric actuators, lifting assembly 702, and winch 10 involved in this invention are all existing general-purpose products, and they are all controlled by a controller. This allows for precise control of the movements of the first motor 15, second motor 707, third motor 605, fourth motor 612, fifth motor 616, first electric actuator 621, second electric actuator 58, winch 10, and lifting assembly 702, based on the anti-deformation operation and auxiliary handling operation of the steel pipe pile 3. The first motor 15, second motor 707, and third motor 605... The start and end of each action of the fourth motor 612, the fifth motor 616, the first electric push rod 621, the second electric push rod 58, the winch 10, and the lifting assembly 702 are obtained through repeated experiments and stored in the controller for easy retrieval later. Thus, when performing anti-deformation operations and auxiliary handling operations on the steel pipe piles 3, only the corresponding program instruction needs to be selected. This is the conventional control setting for the motors, electric push rods, lifting assembly 702, and winch 10, a technology known to industry professionals, and therefore will not be elaborated upon here.

[0047] The present invention discloses a handling process for a steel pipe pile auxiliary handling system based on a crane vessel, such as... Figures 1-16 As shown, it includes the following steps: (1) During the storage and transportation of steel pipe pile 3 (1.1) First, the placement plate II4 is lowered to the lower limit position by the synchronous unwinding of the winch 10. Then, the steel pipe pile 3 is horizontally and longitudinally supported on the support block II704 of the material taking mechanism 7. Then, the steel pipe pile 3 is horizontally and longitudinally supported in the corresponding placement slot II of the placement plate II4 one by one by the synchronous horizontal and vertical movement of the material taking mechanism 7.

[0048] (1.2) Then, by the synchronous winding of the winch 10, the placement plate II 4 is raised to the upper limit position, and then by the synchronous horizontal and vertical movement of the material taking mechanism 7, the steel pipe piles 3 are horizontally and longitudinally supported one by one in the corresponding placement slot I of the placement plate I 2.

[0049] (1.3) Then, by the synchronous unwinding of the winch 10, the placement plate II4 is lowered and supported on the corresponding upper cover 51 of the lower layer steel pipe pile 3. At this time, the storage and transportation of the steel pipe pile 3 can be carried out.

[0050] (1.4) Every so often, driven by the third motor 605, the two moving plates 601 move toward each other to their limit positions, and each sleeve 620 is coaxially fitted onto the two ends of the corresponding steel pipe pile 3 in the lower layer. Then, the pushing end of the first electric push rod 621 extends, so that the pressure plate 622 is in close contact with the corresponding position of the surface of the steel pipe pile 3 through the second rubber pad. At this time, driven by the fifth motor 616, the gear shaft 615 rotates around its own axis, which can drive the corresponding steel pipe pile 3 to rotate, thereby preventing the deformation of the lower layer steel pipe pile 3.

[0051] (1.5) Then the pushing end of the first electric push rod 621 retracts, causing the pressure plate 622 to detach from the surface of the corresponding steel pipe pile 3; then, driven by the third motor 605, the two moving plates 601 move back to back to the limit position, and the sleeve 620 detaches from the corresponding steel pipe pile 3; then, driven by the fourth motor 612, the sleeve 620 rises with the moving block 613 to the upper limit position, and then, driven by the third motor 605, the two moving plates 601 move towards each other to the limit position, and each sleeve 620 is coaxially sleeved at both ends of the corresponding upper layer steel pipe pile 3. Then, repeating the above steps can prevent the upper layer steel pipe pile 3 from deforming.

[0052] (2) When it is necessary to move the steel pipe pile 3 out of the frame 1 and onto the vertical pile device 19 (2.1) First, the pushing end of the first electric push rod 621 retracts, causing the pressure plate 622 to detach from the surface of the corresponding steel pipe pile 3; then, driven by the third motor 605, the two moving plates 601 move back to their extreme positions, causing the sleeve 620 to detach from the corresponding steel pipe pile 3.

[0053] (2.2) Then, by the synchronous winding of the winch 10, the placement plate II4 is raised and detached from the corresponding hoisting component 5 of the lower layer steel pipe pile 3.

[0054] (2.3) Then, driven by the second motor 707, the support block II 704 moves horizontally to the left along with the bottom plate 701 to the position inside the frame 1 relative to the rightmost steel pipe pile 3. Then, by the rise of the top plate 703, the support block II 704 lifts the rightmost steel pipe pile 3 of the lower layer and removes it from the placement plate I 2. Then, driven by the second motor 707, the support block II 704 moves horizontally to the right along with the bottom plate 701 to the right limit position and moves the rightmost steel pipe pile 3 of the lower layer out of the frame 1.

[0055] (2.4) Then, driven by the first motor 15, the two placement plates III11 move towards each other to their limit positions. Then, by the descent of the upper top plate 703, the steel pipe pile 3 is supported on the two placement plates III11 by the hoisting assembly 5. At this time, the pushing end of the second electric push rod 58 retracts, causing the clamping plate 59 to detach from the corresponding steel pipe pile 3. Then, driven by the first motor 15, the two placement plates III11 move away from each other to their limit positions, so that the two hoisting assemblies 5 can detach from the corresponding steel pipe pile 3 respectively.

[0056] (2.5) Then, in a low-altitude state, the lifting device 21 is tied to the steel pipe pile 3, and the steel pipe pile 3 can be lifted onto the vertical pile device 19 by the crane 20 of the crane ship cooperating with the lifting device 21.

[0057] (2.6) Then repeat the above steps to move the lower layer steel pipe piles 3 out of the frame 1 one by one and hoist them onto the vertical pile device 19; then, through the synchronous unwinding of the winch 10, the placement plate II 4 is lowered to the lower limit position. At this time, repeat the above steps to move the upper layer steel pipe piles 3 out of the frame 1 one by one and hoist them onto the vertical pile device 19.

[0058] The beneficial effects of this invention are: (1) By using the hoisting assembly 5, placement plate I 2, placement plate II 4, wire rope 9, winch 10, material handling mechanism 7 and crane 20 in combination, the present invention can not only stack several steel pipe piles 3 in an orderly manner in the frame 1 for overall transportation, saving space, but also facilitate the removal of steel pipe piles 3 one by one from the frame 1 and hoisting them onto the vertical pile device 19 in a low-altitude operation state. This process is time-saving and labor-saving, and avoids high-altitude operation, with high safety. (2) By setting up the hoisting assembly 5, the present invention not only facilitates the hoisting of the steel pipe pile 3, but also works with the placement plate I2 and the placement plate II4 to ensure that the steel pipe pile 3 is stacked in an orderly manner in the frame 1, thereby saving space. (3) By using the placement plate Ⅲ11, the first slide rail 12, the first slider 13, the first fixing plate 14, the first motor 15, the first gear 16, the first rack 17 and the first limiting block 18 in combination, the present invention can automatically detach the hoisting component 5 from the corresponding steel pipe pile 3 after the steel pipe pile 3 is removed from the frame 1, so that the hoisting tool 21 can be tied to the corresponding steel pipe pile 3 in the low-altitude operation state, and then the steel pipe pile 3 can be hoisted to the vertical pile device 19 by the crane 20 for subsequent turning operation. This process saves time and effort and improves work efficiency. (4) By setting up an anti-deformation mechanism 6, the present invention can drive the corresponding steel pipe pile 3 to rotate along its own axis one by one. This process not only saves time and effort, but also avoids the steel pipe pile 3 from deforming due to long placement time.

Through the cooperation of the third slider and the corresponding third slide rail, the two moving plates can move horizontally and longitudinally within the frame relative to the front and rear sides of the steel pipe pile. At the front and rear ends of each lower-level steel pipe pile, sleeves are coaxially fitted onto the outer sides of the corresponding hoisting components. The surface of each sleeve near the corresponding steel pipe pile is open, while its inner surface away from the steel pipe pile is in contact with the front and rear end faces of the corresponding steel pipe pile. The inner diameter of each sleeve is larger than the outer diameter of the steel pipe pile, and a frustum-shaped locking block matching the interior of the steel pipe pile is coaxially fixed to its inner surface away from the steel pipe pile. This locking block is then inserted into the corresponding steel pipe pile to ensure the stability of the steel pipe pile when it rotates around its own axis using the anti-deformation mechanism. Furthermore, along the circumferential direction of the outer circumference of each sleeve, there are sequentially... Several first electric push rods are arranged radially along the sleeve at intervals. The pushing end of each electric push rod extends vertically into the interior of the sleeve and is screwed and fixed to the corresponding pressure plate. A second rubber pad is also fixedly attached to one side of each pressure plate near the corresponding locking block. Driven by the first electric push rods, the second rubber pads on the pressure plate abut against the corresponding position on the surface of the steel pipe pile, so that the sleeve is connected to the corresponding steel pipe pile. The pushing end of each first electric push rod must ensure that the pressure plate is in contact with the corresponding position on the surface of the steel pipe pile when it extends to its limit position, and its retracted limit position must ensure that the pressure plate is disengaged from the surface of the corresponding steel pipe pile. On the upper surface of each movable plate, a hollow cuboid frame is vertically provided relative to each sleeve position. The surface of each frame near the steel pipe pile is open, and each frame is fixedly installed on the upper surface of the corresponding movable plate by a fixing seat, ensuring that adjacent frames on the same movable plate are arranged in a straight line with left and right spacing. Two threaded rods are vertically symmetrically arranged at left and right intervals in the middle of the interior of each frame. The lower end of each threaded rod is rotatably connected to the inner bottom surface of the corresponding frame about its own axis, and its upper end extends vertically upward from the upper surface of the corresponding frame, and is linked to the output end of the corresponding fourth motor. The two fourth motors on the same frame operate synchronously, and are vertically symmetrically arranged on the front and rear sides of each threaded rod within the interior of each frame. The frame is equipped with guide rails, and the upper and lower ends of each guide rail are fixedly connected to the inner top and inner bottom surfaces of the frame, respectively. Each threaded rod is also fitted with a movable block at intervals, and the four movable blocks within the same frame are arranged in a rectangular symmetrical configuration. Each movable block is screwed to the corresponding threaded rod and vertically slidably connected to the corresponding two guide rails. The four movable blocks within the same frame extend vertically from the steel pipe pile side of the corresponding frame and are connected to the outer surface of the corresponding sleeve away from the steel pipe pile via a rotating assembly. Driven by a fourth motor, the sleeve moves vertically up and down with the movable blocks, ensuring that the sleeve is coaxial with the uppermost corresponding steel pipe pile when at its upper limit position and with the lowermost corresponding steel pipe pile when at its lower limit position. On the deck of the crane vessel, a third rack is horizontally and longitudinally arranged directly below each movable plate and between each pair of adjacent frames. The length of each third rack is consistent with the length of the corresponding third slide rail, and the two are aligned and do not interfere with each other. The teeth of each third rack are horizontally arranged facing the right and are fixedly mounted on the deck of the crane vessel by stiffeners. A third motor is vertically arranged on the upper surface of each movable plate relative to each third rack. The operation of each third motor on the same movable plate is synchronized, and they are spaced apart between adjacent fixed seats. The output ends of the three motors extend vertically downwards from the lower surface of the corresponding moving plates, and are respectively connected to the corresponding third rack via a third gear. Driven by the third motor, the two moving plates move horizontally and longitudinally within the frame relative to the front and rear sides of the steel pipe pile through the meshing of the third gear and the corresponding third rack. The horizontal movement limit position of the two moving plates toward the steel pipe pile must ensure that the sleeve can be coaxially fitted onto both ends of the corresponding steel pipe pile, and the horizontal movement limit position away from the steel pipe pile must ensure that the sleeve can be disengaged from both ends of the corresponding steel pipe pile, without interfering with the action of the material handling mechanism to remove the steel pipe pile from the frame.

9. The steel pipe pile auxiliary handling system based on a crane vessel according to claim 8, characterized in that: Each of the rotating components includes a housing, a gear shaft, a fifth motor, a main bevel gear, a driven bevel gear, and a roller assembly. A hollow cylindrical housing is coaxially positioned between each sleeve and the corresponding frame. The outer surface of each housing, away from the corresponding sleeve, is fixedly connected to four corresponding moving blocks, allowing it to move vertically up and down with the moving blocks and horizontally with the moving plate. A gear shaft is horizontally positioned in the middle of the interior of each housing. Each gear shaft is rotatably connected to the corresponding housing around its own axis, and its end near the sleeve extends horizontally outward from the corresponding housing, coaxially fixedly connected to the outer surface of the corresponding sleeve away from the steel pipe pile. A series of gears are mounted on each gear shaft. A driven bevel gear is coaxially sleeved and fixed inside the corresponding housing, and each housing does not interfere with the rotation of the driven bevel gear with the corresponding gear shaft. Inside each housing, a fifth motor is vertically installed directly above the driven bevel gear, and the two fifth motors acting on the same steel pipe pile operate synchronously. The fixed end of each fifth motor is screwed to the inner top surface of the corresponding housing, and its output end is vertically downward towards the corresponding driven bevel gear. They are respectively connected to the corresponding driven bevel gear through the meshing of the main bevel gear and the corresponding driven bevel gear. Under the drive of the fifth motor, through the meshing of the main bevel gear and the corresponding driven bevel gear, the sleeve rotates horizontally around its own axis with the gear shaft, and drives the corresponding steel pipe pile to rotate around its own axis. Several sets of rollers are connected to the outer surface of each box body near the steel pipe pile, and these roller sets are all coaxially arranged with the corresponding box body and are not interfered with by the corresponding gear shaft. Each set of rollers is conical, with one end near the corresponding gear shaft being the small end and the other end being the large end, so as to accommodate a smaller linear velocity near the gear shaft when the box body rotates.

10. The handling process of a steel pipe pile auxiliary handling system based on a crane vessel according to claim 9, characterized in that... Includes the following steps: (1) During the storage and transportation of steel pipe piles (1.1) First, by synchronously unwinding the winch, the placement plate II is lowered to the lower limit position. Then, the steel pipe piles are horizontally and longitudinally supported on the support block II of the material taking mechanism. Then, by synchronously moving the horizontal and vertical sides of the material taking mechanism, the steel pipe piles are horizontally and longitudinally supported one by one in the corresponding placement slot II of the placement plate II. (1.2) Then, by the synchronous winding of the winch, the placement plate II is raised to the upper limit position, and then by the synchronous horizontal and vertical movement of the material taking mechanism, the steel pipe piles are horizontally and longitudinally supported one by one in the corresponding placement slot I of the placement plate I. (1.3) Then, by synchronously unwinding the winch, the placement plate II is lowered and supported on the corresponding upper cover of the lower layer of steel pipe piles. At this time, the storage and transportation of steel pipe piles can be carried out. (1.4) Every once in a while, driven by the third motor, the two moving plates move towards each other to their limit positions, and each sleeve is coaxially fitted onto the two ends of the corresponding steel pipe pile in the lower layer. Then the pushing end of the first electric push rod extends, so that the pressure plate is pressed against the corresponding position of the surface of the steel pipe pile through the second rubber pad. At this time, driven by the fifth motor, the gear shaft rotates around its own axis, which can drive the corresponding steel pipe pile to rotate, thereby preventing the deformation of the steel pipe pile in the lower layer. (1.5) Then the pushing end of the first electric push rod retracts, causing the pressure plate to detach from the surface of the corresponding steel pipe pile; then, driven by the third motor, the two moving plates move back to back to the limit position, causing the sleeve to detach from the corresponding steel pipe pile. Then, driven by the fourth motor, the sleeve rises to the upper limit position with the moving block. Then, driven by the third motor, the two moving plates move towards each other to the limit position, and each sleeve is coaxially sleeved on both ends of the corresponding upper steel pipe pile. Repeating the above steps can prevent deformation of the upper steel pipe pile. (2) When it is necessary to move the steel pipe piles out of the frame and onto the vertical pile device (2.1) First, the pushing end of the first electric push rod retracts, causing the pressure plate to detach from the surface of the corresponding steel pipe pile; then, driven by the third motor, the two moving plates move back to back to their limit positions, causing the sleeve to detach from the corresponding steel pipe pile. (2.2) Then, by synchronous winding of the winch, the placement plate II is raised and detached from the corresponding hoisting component of the lower layer of steel pipe pile; (2.3) Then, driven by the second motor, the support block II moves horizontally to the left along with the bottom plate to the position inside the frame relative to the rightmost steel pipe pile. Then, by the rise of the top plate, the support block II lifts the rightmost steel pipe pile of the lower layer and removes it from the placement plate I. Then, driven by the second motor, the support block II moves horizontally to the right along with the bottom plate to the right limit position and moves the rightmost steel pipe pile of the lower layer out of the frame. (2.4) Then, driven by the first motor, the two placement plates III move towards each other to their limit positions. Then, by the descent of the top plate, the steel pipe pile is supported on the two placement plates III by the hoisting assembly. At this time, the pushing end of the second electric push rod retracts, causing the clamping plate to detach from the corresponding steel pipe pile. Then, driven by the first motor, the two placement plates III move away from each other to their limit positions, so that the two hoisting assemblies can detach from the corresponding steel pipe piles respectively. (2.5) Then, in a low-altitude state, the lifting device is tied to the steel pipe pile, and the steel pipe pile can be lifted onto the vertical pile device by the crane of the crane ship in coordination with the lifting device. (2.6) Then repeat the above steps to move the lower layer steel pipe piles out of the frame one by one and hoist them onto the vertical pile device; then, through the synchronous unwinding of the winch, the placement plate II is lowered to the lower limit position. At this time, repeat the above steps to move the upper layer steel pipe piles out of the frame one by one and hoist them onto the vertical pile device.
