Description

[0001] Pile turning mechanism and steel pipe pile Technical Field

[0002] This application relates to the field of offshore wind power technology, and in particular to a pile-turning mechanism and a steel pipe pile. Background Technology

[0003] A steel pipe pile turning mechanism is a device specifically designed to clamp, lift, and flip steel pipe piles lying flat on the ground or other platforms, and then hoist them to a designated location. This type of mechanism is particularly important in marine engineering, bridge construction, and dock construction, especially in offshore wind power projects. As the diameter and weight of the pipe piles increase, traditional pile lifting methods can no longer meet construction requirements, thus highlighting the growing importance of steel pipe pile turning mechanisms.

[0004] Currently, the typical process for turning steel pipe piles under jacket supports involves installing two tubular lifting lugs on the outer wall of the steel pipe pile, and turning the pile through these lugs. Since the steel pipe pile needs to pass through the guide structure during subsequent pile driving, the lifting lugs often need to be removed to avoid conflict with the guide structure.

[0005] However, existing technology requires the removal of the lifting lugs, which can easily reduce the durability of the pile body and is time-consuming, labor-intensive, and material-intensive, resulting in high pile flipping costs. Utility Model Content

[0006] This application provides a pile-turning mechanism and a steel pipe pile to solve the problems of low pile durability, high time, labor and material consumption, and high pile-turning cost caused by the need to cut off the lifting lugs when turning piles.

[0007] In a first aspect, embodiments of this application provide a pile-turning mechanism applied to steel pipe piles. One end of the steel pipe pile is open, and the inner wall of the steel pipe pile is provided with lifting lugs. The pile-turning mechanism includes:

[0008] The support rod is fixedly connected to the inner wall of the steel pipe pile from the opening, and the length of the support rod is variable;

[0009] Sliding component, which is connected to the support rod;

[0010] The lifting component has one end fixedly connected to the lifting lug, and the other end of the lifting component passes around the sliding component and is connected to the lifting mechanism.

[0011] When the hoisting mechanism pulls upward, the hoisting component drives the end of the steel pipe pile with the support rod to move upward in the vertical direction so that the steel pipe pile is in an upright state.

[0012] The pile-turning mechanism described above can optionally have a cross-shaped support rod.

[0013] The pile-turning mechanism described above may optionally include a cross-shaped central rod, an adjustable lead screw, and a strut.

[0014] The cross-shaped center rod includes four connecting rods;

[0015] The adjustable lead screw includes a first end and a second end;

[0016] Each connecting rod is movably connected to the first end of an adjustable lead screw;

[0017] The second end of each adjustable lead screw is movably connected to a strut.

[0018] The above-mentioned pile-turning mechanism can optionally have a sliding component that is rotatably connected to the support rod.

[0019] The above-mentioned pile-turning mechanism can optionally have two sliding parts;

[0020] The two sliding parts are symmetrically arranged, and each sliding part is connected to the strut.

[0021] As described above, the pile-turning mechanism can optionally have the second end of each adjustable lead screw rotatably connected to a strut.

[0022] As shown in the above pile-turning mechanism, optionally, each sliding member is rotatably connected to the strut.

[0023] For the pile-turning mechanism described above, the optional lifting component is a steel wire rope.

[0024] Secondly, embodiments of this application provide a steel pipe pile, including a pile body and lifting lugs;

[0025] The lifting lugs are fixedly installed on the inner wall of the pile body and are used to connect the pile turning mechanism as described above.

[0026] The steel pipe piles mentioned above may also include, optionally, anti-detachment caps;

[0027] The anti-detachment cover is movably connected to the lifting lug to prevent the pile-turning mechanism connected to the lifting lug from falling off.

[0028] This application provides a pile-turning mechanism and a steel pipe pile. The pile-turning mechanism is applied to a steel pipe pile, one end of which is open, and the inner wall of the steel pipe pile is provided with a lifting lug. The pile-turning mechanism includes: a support rod, which is fixedly connected to the inner wall of the steel pipe pile from the opening, and the length of the support rod is variable; a sliding member, which is connected to the support rod; and a lifting member, one end of which is fixedly connected to the lifting lug, and the other end of which passes around the sliding member and is connected to the lifting mechanism. When the lifting mechanism pulls upward, the lifting member drives the end of the steel pipe pile with the support rod to move upward in the vertical direction, so that the steel pipe pile is in an upright state. By installing lifting lugs inside the steel pipe pile, the lifting components bypass the sliding parts and connect with the lifting lugs and lifting mechanism to perform pile turning. This eliminates the need to cut off the lifting lugs or use a special pile turning device, saving time and effort. It solves the problems of low pile durability, high time, labor, and material costs associated with cutting off the lifting lugs during pile turning, and high pile turning costs. Furthermore, by setting up a support rod with variable length, it can be adjusted according to different pile diameters, adapting to the construction of steel pipe piles with different diameters.

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this application. Rather, they are merely examples of apparatuses and devices consistent with some aspects of the embodiments of this application as detailed in the appended claims.

[0046] In the embodiments of this application, terms such as "first" and "second" are used to distinguish identical or similar items with essentially the same function and purpose. For example, "first chip" and "second chip" are used only to distinguish different chips and do not limit their order of execution. Those skilled in the art will understand that terms such as "first" and "second" do not limit the quantity or execution order, and that "first" and "second" do not necessarily imply that they are different.

[0047] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner. In the embodiments of this application, "at least one" refers to one or more, and "more than one" refers to two or more.

[0048] It should be noted that the phrase "at...time" in the embodiments of this application can refer to the instant at which a certain situation occurs, or to a period of time after the occurrence of a certain situation; the embodiments of this application do not specifically limit this. Furthermore, the pile-turning mechanism and steel pipe pile provided in the embodiments of this application are merely examples, and the pile-turning mechanism and steel pipe pile may include more or fewer components.

[0049] The current process for turning steel pipe piles under jacket supports typically involves installing two tubular lifting lugs on the outer wall of the steel pipe pile, and turning the pile through these lugs. However, since the steel pipe pile needs to pass through the guide structure during subsequent pile driving, the lugs often need to be cut off to avoid conflict with the guide structure. This process is time-consuming, labor-intensive, and material-intensive. Furthermore, cutting off the lugs carries the risk of damaging the parent material and the coating of the steel pipe pile, affecting the pile's durability.

[0050] Another method of pile turning is to use a special pile turning device, which is clamped on the pipe wall at the top of the pile to turn the pile, but the rental cost of the pile turning device is high.

[0051] In summary, in the existing technology, pile flipping requires the removal of the lifting lugs, which can easily reduce the durability of the pile body, and is time-consuming, labor-intensive, and material-intensive, resulting in high pile flipping costs.

[0052] Based on this, this application provides a pile-turning mechanism and a steel pipe pile, which is applied to steel pipe piles. By setting lifting lugs inside the steel pipe pile, the lifting component bypasses the sliding component and connects with the lifting lugs and the lifting mechanism to turn the pile. This eliminates the need to cut off the lifting lugs or use a special pile-turning device, saving time and effort. It solves the problems of low pile durability, high time, labor, and material costs associated with cutting off the lifting lugs during pile turning, and high pile turning costs. By setting a support rod with variable length, it can be adjusted according to different pile diameters to adapt to the construction of steel pipe piles with different diameters.

[0053] It can be used in the field of offshore wind power technology to solve the above-mentioned technical problems of existing technologies.

[0054] Figure 1 This is a side view of the pile-turning mechanism provided in an embodiment of this application. Figure 2 This is a front view of the pile-turning mechanism provided in an embodiment of this application.

[0055] like Figure 1 and Figure 2 As shown, this application embodiment provides a pile-turning mechanism 100, applied to a steel pipe pile 200. One end of the steel pipe pile 200 is open, and the inner wall of the steel pipe pile 200 is provided with a lifting lug 220. The pile-turning mechanism 100 includes:

[0056] The support rod 110 is fixedly connected to the inner wall of the steel pipe pile 200 from the opening, and the length of the support rod 110 is variable;

[0057] Sliding member 120, which is connected to support rod 110;

[0058] The lifting component 130 has one end fixedly connected to the lifting lug 220, and the other end of the lifting component 130 passes around the sliding component 120 and is connected to the lifting mechanism.

[0059] When the hoisting mechanism pulls upward, the hoisting component 130 drives the end of the steel pipe pile 200 with the support rod 110 to move upward in the vertical direction so that the steel pipe pile 200 is in an upright state.

[0060] For example, the support rod 110 may consist of multiple rods, which are connected by sleeves to adjust the length of the support rod 110. The sleeve connection may be equipped with threads, pins or other fixing devices, and methods such as thread locking, pin fixing, and press-fitting can be used to prevent the multiple rods from moving relative to each other or falling off when under force.

[0061] For example, the lifting component 130 can be fitted onto the lifting lug 220 for fixed connection, or it can be fixedly connected in other ways.

[0062] It should be understood that when the hoisting mechanism pulls upward, the hoisting component 130 bypasses the sliding component 120 and is fixedly connected to the lifting lug 220, so that the traction force is applied to the lifting lug 220, driving the end of the steel pipe pile 200 with the support rod 110 to move upward in the vertical direction, so that the steel pipe pile 200 is in an upright state, and the pile flipping is completed.

[0063] By setting a lifting lug 220 inside the steel pipe pile 200, and the lifting component 130 bypassing the sliding component 120 and connecting with the lifting lug 220 and the lifting mechanism to flip the pile, the steel pipe pile 200 does not need to be cut off the lifting lug 220 or a special pile flipping device is required for pile flipping. This saves time and effort and solves the problem that the removal of the lifting lug 220 is required for pile flipping, resulting in low pile durability, and is time-consuming, labor-intensive, material-intensive, and costly. By setting a support rod 110 with a variable length, it can be adjusted according to different pile diameters to adapt to the construction of steel pipe piles 200 with different diameters.

[0064] In some embodiments, the support rod 110 has a cross structure.

[0065] Specifically, the support rod 110 has a cross structure, and the four ends of the support rod 110 are fixedly connected to the inner wall of the steel pipe pile 200 to ensure the stability of the support, so as to ensure the stability of the sliding part 120 connected to the support rod 110.

[0066] In some embodiments, the support rod 110 includes a cross-shaped central rod 111, an adjustable lead screw 112, and a strut 113;

[0067] The cross-shaped center rod 111 includes four connecting rods;

[0068] The adjustable lead screw 112 includes a first end and a second end;

[0069] Each connecting rod is movably connected to the first end of an adjustable lead screw 112;

[0070] The second end of each adjustable lead screw 112 is movably connected to a support rod 113.

[0071] For example, the movable connection between the adjustable lead screw 112 and the connecting rod and support rod 113 can be achieved by a sleeve connection. It can be a sleeve connection with threads, pins or other fixing devices, and can be tightened by thread locking, pin fixing, press-fitting and fastening to prevent the multiple rods from moving relative to each other or falling off when under force.

[0072] For example, the movable connection between the adjustable lead screw 112 and the connecting rod and the movable connection between the adjustable lead screw 112 and the support rod 113 can be the same or different.

[0073] For example, each connecting rod of the cross-shaped center rod 111 has an internal thread of a certain length at one end connected to the adjustable lead screw 112, and the support rod 113 also has an internal thread of a certain length at one end connected to the adjustable lead screw 112. The length of the internal thread can be set according to the actual situation. The adjustable lead screw 112 has an external thread, and both ends of each adjustable lead screw 112 are respectively engaged with the connecting rod and the support rod 113 to adjust the length of the support rod 110.

[0074] It should be understood that the cross center rod 111 is set in the middle of the opening at one end of the steel pipe pile 200, and the support rod 113 is fixedly connected to the inner wall of the steel pipe pile 200 from the opening. One end of the adjustable screw rod 112 is connected to the cross center rod 111, and the other end is connected to the support rod 113. Depending on the specific method of the movable connection, the exposed length of the adjustable screw rod 112 can be adjusted by means of rotation or extension, thereby adjusting the length of the support rod 110. It can be adjusted according to different pile diameters to adapt to the construction of steel pipe piles 200 with different pile diameters.

[0075] In some embodiments, the slider 120 is rotatably connected to the support rod 110.

[0076] For example, the slider 120 may be composed of one or more pulleys, or it may be other sliders 120 that change the direction of the lifting member 130.

[0077] For example, the rotatable connection between the slider 120 and the support rod 110 can be achieved by a bearing connection or by other means.

[0078] It should be understood that the sliding element 120 is mounted on the support rod 110, and one edge of the sliding element 120 is exposed at the opening of the steel pipe pile 200 to avoid friction between the lifting component 130 and the steel pipe pile 200.

[0079] One end of the lifting component 130 is fixedly connected to the lifting lug 220, and the other end passes around the sliding component 120 to change direction so as to facilitate connection with the lifting mechanism.

[0080] In some embodiments, the number of sliders 120 is two;

[0081] Two sliding members 120 are symmetrically arranged, and each sliding member 120 is connected to the support rod 113.

[0082] Specifically, two connecting rods of the cross center rod 111 are parallel to the ground, and the other two connecting rods are perpendicular to the ground. Each connecting rod is directly connected to an adjustable lead screw 112 and indirectly connected to a support rod 113, dividing the support rod 110 into two parts: one parallel to the ground and the other perpendicular to the ground.

[0083] Two sliding members 120 are symmetrically arranged on a portion of the support rod 110 that is parallel to the ground to ensure the stability of the pile-turning mechanism 100 when the hoisting mechanism pulls upward.

[0084] In some embodiments, the second end of each adjustable lead screw 112 is rotatably connected to a support rod 113.

[0085] Specifically, rotary connections can be achieved through threaded connections.

[0086] Each connecting rod of the cross center rod 111 has an internal thread of a certain length at one end connected to the adjustable lead screw 112. The support rod 113 also has an internal thread of a certain length at one end connected to the adjustable lead screw 112. The length of the internal thread can be set according to the actual situation.

[0087] The adjustable lead screw 112 is provided with an external thread, and both ends of each adjustable lead screw 112 are respectively engaged with the connecting rod and the support rod 113 to adjust the length of the support rod 110. The length of the support rod 110 is adjusted by means of threaded connection, which is simple in structure and easy to operate.

[0088] In some embodiments, each slider 120 is rotatably connected to the strut 113.

[0089] For example, the rotatable connection between the slider 120 and the support rod 113 can be achieved by a bearing connection or by other means.

[0090] It should be understood that the sliding member 120 is set on the strut 113 of the support rod 110, that is, on the side of the support member close to the inner wall of the steel pipe pile 200. One end of the lifting member 130 is fixedly connected to the lifting lug 220, and the other end passes around the sliding member 120 to change direction so as to facilitate connection with the lifting mechanism.

[0091] In some embodiments, the lifting component 130 is a wire rope.

[0092] The lifting component 130 is a steel wire rope, which has the characteristics of high strength and wear resistance.

[0093] For example, the lifting component 130 includes a lifting wire rope, a lifting beam, and a connecting wire rope. The lifting wire rope is fixedly connected to the lifting lug 220. The lifting beam connects the lifting wire rope and the connecting wire rope. When the lifting mechanism pulls upward, the connecting wire rope is connected to the main hook of the crane of the lifting mechanism. The main hook of the crane slowly rises, realizing the flipping of the steel pipe pile 200.

[0094] Figure 3 This is a schematic diagram of the pile-turning mechanism and steel pipe pile provided in the embodiments of this application.

[0095] like Figure 3 As shown, this application embodiment provides a steel pipe pile 200, including a pile body 210 and a lifting lug 220;

[0096] The lifting lug 220 is fixedly installed on the inner wall of the pile body 210. The lifting lug 220 is used to connect the pile turning mechanism 100 as described above.

[0097] For example, the number of lugs 220 can be two, or the number can be selected according to the actual situation.

[0098] For example, the lifting lug 220 can be fixed to the inner wall of the pile body 210 by welding, or it can be fixed to the inner wall of the pile body 210 by other means.

[0099] It should be understood that when the lifting mechanism pulls upward, the connecting line of the two lifting lugs 220 is parallel to the ground, so that one end of the lifting component 130 is fixedly connected to the lifting lug 220, and the other end passes around the sliding component 120.

[0100] In some embodiments, an anti-detachment cover 230 is also included;

[0101] The anti-detachment cover plate 230 is movably connected to the lifting lug 220 to prevent the pile turning mechanism 100 connected to the lifting lug 220 from falling off.

[0102] In one example, lifting lugs 220 are installed on both sides of the inner wall of the steel pipe pile 200, anti-detachment cover 230 is installed on the lifting lugs 220, support rod 110 is supported on the inner wall of the opening of the steel pipe pile 200 to provide support for the pulley, the lifting wire rope is hung on the lifting lugs 220, the anti-detachment cover 230 fixes the lifting wire rope, the lifting wire rope is turned by the pulley, connected to the lifting beam, and connected to the main hook of the crane by the connecting wire rope.

[0103] When the hoisting mechanism pulls upward, the connecting wire rope is connected to the main hook of the hoisting mechanism. The main hook of the hoisting mechanism is slowly lifted, and one end of the steel pipe pile 200 with the support rod 110 moves upward in the vertical direction, realizing the turning of the steel pipe pile 200.

[0104] This application provides a pile-turning mechanism 100 and a steel pipe pile 200. The pile-turning mechanism 100 is applied to the steel pipe pile 200, one end of which is open, and the inner wall of the steel pipe pile 200 is provided with a lifting lug 220. The pile-turning mechanism 100 includes: a support rod 110, which is fixedly connected to the inner wall of the steel pipe pile 200 from the opening, and the length of the support rod 110 is variable; a sliding member 120, which is connected to the support rod 110; and a lifting member 130, one end of which is fixedly connected to the lifting lug 220, and the other end of which passes around the sliding member 120 and is connected to the lifting mechanism. When the lifting mechanism pulls upward, the lifting member 130 drives the end of the steel pipe pile 200 with the support rod 110 to move upward in the vertical direction, so that the steel pipe pile 200 is in an upright state.

[0105] By setting a lifting lug 220 inside the steel pipe pile 200, the lifting component 130 bypasses the sliding component 120 and connects with the lifting lug 220 and the lifting mechanism to flip the pile. This eliminates the need to cut off the lifting lug 220 or use a special pile flipping device to flip the pile, saving time and effort. It solves the problem that the pile body has low durability due to the need to cut off the lifting lug 220 when flipping the pile, and that it is time-consuming, labor-intensive, material-intensive, and costly.

[0106] The cross center rod 111 and the support rod 113 are connected by an adjustable screw rod 112. By adjusting the screw rod, the support rod 110 can be extended or shortened to accommodate steel pipe piles 200 of different diameters. It can be adjusted according to different pile diameters to adapt to the construction of steel pipe piles 200 of different diameters.

[0107] By setting the anti-detachment cover plate 230, the lifting component 130 is stably connected to the lifting lug 220, preventing the pile turning mechanism 100 connected to the lifting lug 220 from falling off.
