Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering, in particular to a piling and lifting dual-purpose system and a piling and lifting dual-purpose ship. Background Art

[0002] The traditional luffing pile-driving barge is a kind of equipment commonly used in the pile foundation construction of marine engineering projects such as hydraulic high-pile docks and large bridges. It generally includes a hull, a trunk beam fixedly connected to the hull, a luffing cylinder, a pile frame structure and pile driving equipment installed on the pile frame, such as a pile hammer, a pile cap and a pile gripper. With the large-scale development of docks, bridges and other equipment, the pile diameter and pile weight of the pile foundation are also getting larger and larger. The maximum pile length of a certain project has exceeded 134 meters, the maximum pile diameter has exceeded 7.5 meters, and the maximum pile weight has exceeded 1,100 tons. Therefore, the size and carrying capacity of the core structures such as the pile frame of the traditional luffing pile-driving barge are also becoming larger and larger, resulting in the development and manufacturing costs of single-purpose luffing pile-driving barges becoming increasingly high and the economic benefits gradually declining. It is necessary to find new uses for the luffing pile-driving barge to improve the economic benefits of the luffing pile-driving barge. Utility Model Content

[0003] The purpose of the utility model is to overcome the technical problems that the development and manufacturing costs of existing traditional variable-luff pile-driving vessels are becoming increasingly high and the economic benefits are gradually declining as the size becomes larger, and to provide a piling and lifting dual-purpose system and a piling and lifting dual-purpose vessel.

[0004] In a first aspect, the present invention provides a piling and lifting dual-purpose system, comprising:

[0005] base;

[0006] A rotating platform is rotatably connected to the base and is provided with a winch;

[0007] Main arm, one end of the main arm is swingably connected to the rotating platform, and the other end of the main arm is used for detachable connection to the lifting structure or piling structure;

[0008] The lifting structure includes a lifting pulley block and a hook. The lifting pulley block is connected to the end of the main arm away from the rotating platform. The hook is connected to the winch through a cable passing around the lifting pulley block.

[0009] The piling structure includes a pile frame and a telescopic support frame; the pile frame is swingably connected to the end of the main arm away from the rotating platform, and the pile frame is connected to a pile hammer, a pile cap and a pile gripper; the two ends of the telescopic support frame are respectively hinged to the rotating platform and the pile frame, and the length of the telescopic support frame is adjustable, thereby being able to drive the pile frame to swing relative to the main arm.

[0010] The piling and lifting dual-purpose system of this scheme is provided with a rotating platform that can rotate on the base, and the main arm is modified into a form that can detachably connect the lifting structure and the piling structure. When the lifting structure is installed on the main arm, this scheme can be used as a lifting system, and the rotation action of the rotating platform, the luffing action of the main arm and the retraction and extension action of the winch are combined to realize lifting actions such as lowering the hook, lifting the hook, and adjusting the position; when the piling structure is installed on the main arm, this scheme can be used as a piling system, and the rotation action of the rotating platform, the luffing action of the main arm, the retraction and extension action of the winch and the telescopic action of the telescopic support frame are combined to realize piling actions such as taking piles, piling and adjusting the position; that is, this scheme has both lifting and piling capabilities, realizing the multi-purpose of the rotating platform and the main arm. Compared with the existing technology that only has the piling function, this scheme has higher economic benefits.

[0011] Preferably, an extension frame is swingably connected to one end of the pile frame away from the main arm, and the extension frame has a first position and a second position. When the extension frame swings to the first position, the extension frame is spliced to the end of the pile frame away from the main arm, thereby lengthening the pile frame; when the extension frame swings to the second position, the extension frame is attached to one side of the pile frame.

[0012] This solution can switch the position of the extension frame according to usage. For example, when it is necessary to drive longer piles, the extension frame can be swung to the first position, thereby increasing the length of the pile frame to accommodate the long piles; when it is not necessary to drive shorter piles, the extension frame can be swung to the second position, thereby reducing the length of the pile frame to accommodate the short piles, and avoiding the extension frame from hindering the pile driving operation.

[0013] Preferably, the main arm comprises at least two segments connected in sequence along its length, the segment closest to the rotating platform is swingably connected to the rotating platform, and the segment closest to the pile frame is used to connect to the lifting structure or pile frame; the two adjacent segments are detachably connected.

[0014] This solution makes the main arm include at least two segments connected in sequence, and each segment can be detachably connected, which can facilitate disassembly, replacement, and increase or decrease of segments to adapt to different task requirements; for example, when a larger operating radius and operating height are required, such as when lifting, the number of segments can be increased, or some segments can be replaced with segments longer than usual; when the operating height needs to be lowered or flexibility needs to be improved, such as when piling, the number of segments can be reduced, or some segments can be replaced with segments shorter than usual.

[0015] Preferably, one end of the main arm away from the rotating platform comprises a first steel box structure, and the first steel box structure is used to connect to the lifting structure or the pile frame.

[0016] This solution adds a first steel box structure to the main boom, increasing the load-bearing capacity and rigidity of the corresponding area of the boom. This allows for both lifting and piling applications, ensuring structural stability in both conditions. The first steel box structure also provides ample flat surfaces, making it easier to arrange components such as the pulleys required for the winch and the hinges for the pile frame.

[0017] Preferably, the end of the pile frame close to the main arm comprises a second steel box structure, and the second steel box structure is used for connecting the pile hammer.

[0018] This solution adds a second steel box structure to the pile frame, which increases the load-bearing capacity and rigidity of the corresponding area of the pile frame, ensuring structural stability during piling. The second steel box structure also has a large number of flat surfaces, making it easier to connect the pile hammer.

[0019] Preferably, a working platform is slidably connected to the pile frame, and the working platform can move along the length direction of the pile frame and reach the end of the pile frame away from the main arm.

[0020] This solution can facilitate equipment or workers to get close to the piles on the working platform, so as to conduct surveys, inspections and other operations on the piles.

[0021] Preferably, the telescopic support frame includes at least two sleeves that are sequentially sleeved and connected, the sleeve closest to the rotating platform is hinged to the rotating platform, and the sleeve closest to the pile frame is hinged to the pile frame. A telescopic cylinder is connected between the two adjacent sleeves, and the telescopic cylinder can drive the two adjacent sleeves to slide against each other when it is extended and retracted, thereby changing the length of the telescopic support frame.

[0022] This proposal recommends a specific form of telescopic support frame. Compared with other structural forms, such as scissor-type planar linkage mechanisms and gear rack mechanisms, the sleeves of this proposal are nested with each other, which can better isolate the interference of the external environment and have more reliable working performance.

[0023] Preferably, at least one of the main arm and the pile frame comprises a truss structure.

[0024] This solution can reduce the windward area of the main arm and the pile frame, thereby reducing the wind load borne by the main arm and the pile frame, making this solution more adaptable to windy environments, such as marine environments.

[0025] In a second aspect, the present invention provides a piling and lifting dual-purpose vessel, comprising a hull, on which a piling and lifting dual-purpose system of the present invention is arranged, and a base is connected to the hull.

[0026] The piling and lifting dual-purpose vessel of this solution is equipped with the piling and lifting dual-purpose system of the present invention, and can switch between the lifting state and the piling state by disassembling and replacing the lifting structure and the piling structure, thus realizing multiple uses of one vessel and having higher economic benefits than the existing dedicated piling vessels.

[0027] Preferably, auxiliary lifting equipment and a shelf bracket are provided on the hull; the shelf bracket is used to support one end of the main arm away from the rotating platform, and the auxiliary lifting equipment is used to disassemble and assemble the lifting structure or the piling structure.

[0028] This solution can support the main arm by placing a bracket, thereby facilitating the disassembly and assembly of auxiliary lifting equipment, replacement of lifting structure or piling structure, and enabling this solution to switch working states automatically, reducing dependence on external equipment.

[0029] 1. The utility model provides a dual-purpose piling and lifting system. On the basis of a base, a rotating platform and a main arm, the main arm is configured to be able to install both a lifting structure and a piling structure, so that the lifting structure and the piling structure can be disassembled and replaced to switch between the lifting state and the piling state, realizing the multi-purpose use of the rotating platform and the main arm. Compared with the existing technology with only the piling function, this solution has higher economic benefits.

[0030] 2. The utility model provides a piling and lifting dual-purpose vessel equipped with the piling and lifting dual-purpose system of the present invention, which can switch between the lifting state and the piling state by disassembling and replacing the lifting structure and the piling structure, thereby realizing multiple uses of one vessel and having higher economic benefits compared with existing special piling vessels.

[0050] Example 1

[0051] like Figures 2 to 12 As shown, a piling and lifting dual-purpose system comprises a base 1, a rotating platform 2, a main arm 3, a lifting structure and a piling structure; the base 1 is used to connect to the ground or a carrier; the rotating platform 2 is rotatably connected to the base 1 through a slewing support and a cycloidal pinwheel, and the rotation angle is greater than or equal to 360 degrees; the rotating platform 2 is provided with equipment such as a winch, a counterweight, a driver's cab, and an attached platform; one end of the main arm 3 is swingably connected to the rotating platform 2; the other end of the main arm 3 is used for detachable connection to the lifting structure or the piling structure, and is provided with a luffing pulley block, and the cable in the winch passes around the luffing pulley block, so that it can be Figures 2 to 3 As shown, the main arm 3 swings by the retraction and extension of the winch.

[0052] The lifting structure includes a lifting pulley set 41 and a hook 42. The lifting pulley set 41 is connected to the end of the main arm 3 away from the rotating platform 2. The hook 42 is connected to the winch through a cable passing around the lifting pulley set 41, so that the hook 42 can be retracted and extended by the retraction and extension of the winch.

[0053] The pile driving structure includes a pile frame 51 and a telescopic support frame 52; the pile frame 51 is swingably connected to the end of the main arm 3 away from the rotating platform 2, and a slide rail is provided along the length direction of the pile frame 51, and a movable hinge seat is slidably connected to the slide rail. The movable hinge seat is connected to the pile hammer 53, pile cap, pile gripper and other equipment required for piling from top to bottom, and the pile hammer 53, pile cap and pile gripper are all connected to the side of the pile frame 51 away from the rotating platform 2; the pile hammer 53, pile cap and pile gripper can adopt existing mature products; the two ends of the telescopic support frame 52 are respectively hinged to the rotating platform 2 and the pile frame 51, and the length of the telescopic support frame 52 is adjustable, so that it can be used as Figures 2 to 3 As shown, the pile frame 51 is driven to swing relative to the main arm 3; the length adjustment of the telescopic support frame 52 can be achieved by a movable or adjustable mechanism including but not limited to a plane connecting rod, a gear rack, a hydraulic cylinder, a pneumatic cylinder, an electric telescopic rod, etc.

[0054] In an optional embodiment, the end of the pile frame 51 away from the main arm 3 is swung and connected to an extension frame 511, and the extension frame 511 has a first position and a second position. When the extension frame 511 swings to the first position, the extension frame 511 is spliced to the end of the pile frame 51 away from the main arm 3, thereby lengthening the pile frame 51; when the extension frame 511 swings to the second position, the extension frame 511 is attached to one side of the pile frame 51. Figures 6 and 7 As shown, the extension frame 511 is hinged to the side of the pile frame 51 close to the rotating platform 2, and its cross-sectional shape matches the pile frame 51; Figure 7 The figure shows the extension frame 511 in the first position, where it can be precisely connected to the lower end of the pile frame 51; Figure 6 The extension frame 511 is shown in the second position. It can be seen that the extension frame 511 can be close to the side of the pile frame 51 close to the rotating platform 2, thereby avoiding interference with the piling operation.

[0055] In an optional embodiment, the main arm 3 includes at least two segments 31 connected in sequence along its length direction. The segment 31 closest to the rotating platform 2 is swingably connected to the rotating platform 2, and the segment 31 closest to the pile frame 51 is used to connect to the lifting structure or the pile frame 51; the adjacent segments 31 are detachably connected. Figure 8 As shown, the main arm 3 includes two segments 31. In this case, the main arm 3 is shorter and more flexible, which is more suitable for pile driving conditions. Figure 9As shown, the main boom 3 includes three segments 31. In this case, the main boom 3 is longer and more suitable for lifting conditions.

[0056] In an optional embodiment, the cross-sectional area of the segment 31 closer to the rotating platform 2 is larger to match the situation where the stress of the main arm 3 is greater as it is closer to the rotating platform 2, so that this solution has stronger structural stability.

[0057] In an optional embodiment, the end of the main arm 3 away from the rotating platform 2 includes a first steel box structure 32, sometimes also called a plate beam structure; the first steel box structure 32 is used to connect the lifting structure or pile frame 51. Figures 1 to 5 As shown, a first steel box structure 32 is provided on the top of the main arm 3. When the lifting structure is installed, it can be seen that the lifting pulley group 41 and its corresponding supporting structure are connected to the first steel box structure 32; when the piling structure is installed, it can be seen that the pile frame 51 is hinged to one side of the first steel box structure 32.

[0058] In an optional embodiment, the end of the pile frame 51 close to the main arm 3 includes a second steel box structure 512, sometimes also called a plate beam structure; the second steel box structure 512 is used to connect the pile hammer 53. Figures 1 to 3 As shown, the second steel box structure 512 is arranged at the top of the pile frame 51. It can be seen that the pulley group and rope winding system required for the pile hammer 53 are distributed above and below the second steel box structure 512, thereby ensuring direct force and enabling the pile frame 51 to withstand the load generated by the pile hammer 53 driving the pile.

[0059] In an optional embodiment, a working platform is slidably connected to the pile frame 51, and the working platform can move along the length of the pile frame 51 and reach the end of the pile frame 51 away from the main arm 3. Working platforms can be provided on both sides of the width of the pile frame 51, that is, on both sides tangential to the rotation direction of the rotating platform 2, so that equipment or personnel can inspect the pile from both sides. The movement of the working platform can be achieved by methods including but not limited to wheel travel, alternating travel of mechanical feet, and retractable cables. The working platform can be provided with an openable and closable movable portion to approach and embrace the pile, so as to facilitate comprehensive inspection of the pile from all sides by equipment or personnel. The movement of the movable portion can be controlled by various methods such as motors, oil cylinders, pneumatic cylinders, and manual control.

[0060] In an optional embodiment, the telescopic support frame 52 includes at least two sleeves 521 that are sequentially sleeved and connected. The sleeve 521 closest to the rotating platform 2 is hinged to the rotating platform 2, and the sleeve 521 closest to the pile frame 51 is hinged to the pile frame 51. A telescopic cylinder 522 is connected between two adjacent sleeves 521. The telescopic cylinder 522 can drive the two adjacent sleeves 521 to slide relative to each other when it is extended and retracted, thereby changing the length of the telescopic support frame 52. Figure 10As shown, the telescopic support frame 52 includes three sleeves 521 that are sequentially sleeved; the sleeves 521 can be box beams with rectangular cross-sections to ensure the bearing capacity.

[0061] In an optional embodiment, if Figures 11 to 12 As shown, at least two groups of sleeves 521 are arranged along the width direction of the telescopic support frame 52, that is, tangentially along the rotation direction of the rotating platform 2. Each group of sleeves 521 includes at least two sleeves 521 arranged in sequence. An intermediate connecting beam is connected between the sleeves 521 in the corresponding positions of two adjacent groups of sleeves 521, and the telescopic cylinder 522 is connected between the two adjacent intermediate connecting beams along the length direction of the telescopic support frame 52. This arrangement can enhance the structural stability of the telescopic support frame 52 on the one hand, reduce the possibility of the telescopic support frame 52 being skewed or even deformed; on the other hand, it is also convenient for Figures 11 to 12 As shown, two or more rows of telescopic cylinders 522 are arranged along the length direction of the middle connecting beam, thereby enhancing the driving force that the telescopic support frame 52 can provide, and further enhancing the control ability of the swing of the pile frame 51; the middle connecting beam can also adopt a box beam with a rectangular cross-section to ensure the bearing capacity.

[0062] In an optional embodiment, at least one of the main arm 3 and the pile frame 51 comprises a truss structure. Figure 1 As shown, the main bodies of the main arm 3 and the pile frame 51 are both truss structures. The main body and diagonal rods of the truss structure are made of square steel pipes, and each connection point is reinforced with steel plates.

[0063] Example 2

[0064] like Figure 1 As shown, a piling and lifting dual-purpose vessel comprises a hull 6 on which a piling and lifting dual-purpose system according to Example 1 is provided. The base 1 of the piling and lifting dual-purpose system is connected to the stern of the hull 6, and a living area is provided at the bow of the hull 6.

[0065] In an optional embodiment, an auxiliary lifting device 8 and a shelf bracket 7 are provided on the hull 6; the shelf bracket 7 is located on one side of the rotating platform 2, and the distance between the shelf bracket 7 and the rotating platform 2 matches the length of the main arm 3, so that Figure 5 As shown, when the main arm 3 is laid down, the main arm 3 is supported at one end away from the rotating platform 2; the shelf bracket 7 can be a single large bracket or a combination of multiple small brackets according to the shape of the main arm 3; the auxiliary lifting equipment 8 is used for disassembling and assembling lifting structures or piling structures, including but not limited to tower cranes and cranes.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
