[0032] In order to make the personnel in the technical field better understand the present application scheme, the present application is further described in detail below in combination with the drawings and specific embodiments.

[0033] For the convenience of understanding and description, the following is described in combination with the turning-over tool and the turning-over system having the same, and the beneficial effect part is not repeated.

[0034] Please refer to Figures 1 to 5 , Figure 1 for the structure schematic diagram of the turning-over tool in the specific embodiment after being hung with the hook portion of the hoisting equipment and the pipe pile; Figure 2 for Figure 1 the structure schematic diagram of the A direction view in the specific embodiment; Figure 3 for Figure 1 the structure schematic diagram of the B direction view in the specific embodiment; Figure 4 for the structure schematic diagram of the pipe pile being turned over to a certain angle by the turning-over tool in the specific embodiment; Figure 5 for the front view of the turning-over tool in the specific embodiment, wherein the third lifting beam and the connecting structure between the third lifting beam and the second lifting beam are omitted.

[0035] In this embodiment, the turning-over system includes the hoisting equipment and the turning-over tool, and can be used for the turning-over operation of the pipe pile 500 which is one of the foundations of the offshore wind power, i.e. turning over the pipe pile 500 from the horizontal posture (as shown in the state of Figure 1 the pipe pile 500 is in the horizontal posture, and its axis is parallel to the horizontal plane, and the pipe pile 500 is in the vertical posture, and its axis is parallel to the vertical direction.

[0036] In this embodiment, the turning-over tool includes the lifting beam 110, the first lifting beam 120, the second lifting beam 130 and the third lifting beam 140; wherein the second lifting beam 130 is hinged to the lifting beam 110, the first lifting beam 120 is hinged to the second lifting beam 130, and the second lifting beam 130 and the third lifting beam 140 are provided with the telescopic structure, and the turning-over tool further includes the driving component 190, which is used for driving the telescopic structure to act to drive the third lifting beam 140 to rise or fall.

[0037] In addition, the lifting beam 110 is provided with at least one lifting lifting point 111 for hanging connection with the hook part 400 of the hoisting device; in the specific scheme, the lifting beam 110 is provided with two lifting lifting points 111, and correspondingly, the hook part 400 of the hoisting device is in the form of double hooks, that is, has two hooks, which are respectively hung and connected with the two lifting lifting points 111.

[0038] Specifically, a lifting sling 210 is arranged at the lifting lifting point 111, and the hanging connection between the lifting beam 110 and the hook part 400 of the hoisting device is achieved by the lifting sling 210.

[0039] Each hook of the hook part 400 can be in the form of a single hook or a double hook, and in the specific scheme, it is in the form of a double hook, that is, two lifting slings 210 are arranged at each lifting lifting point 111, and are respectively connected with the double hooks of the hook at the same position.

[0040] It can be understood that the hook part 400 of the hoisting device is in the form of a double hook, which can improve the stress capacity of the hook part 400, and each hook of the hook part 400 is in the form of a double hook, which can also improve the stress of the hook; in actual setting, the specific structure form of the hook part 400 and the setting of the lifting lifting point 111 can be set according to actual needs, which is not limited here.

[0041] The first lifting beam 120 is provided with at least two first lifting points 121, and the first lifting point 121 is used for hanging connection with the main lifting lug 510 of the pipe pile 500. The third lifting beam 140 is provided with at least one second lifting point 141, and the second lifting point 141 is used for hanging connection with the turning-over lifting lug 520 of the pipe pile 500.

[0042] It can be understood that the number of the first lifting point 121 of the first lifting beam 120 is related to the number of the main lifting lug 510 of the pipe pile 500, and the number of the second lifting point 141 of the third lifting beam 140 is related to the number of the turning-over lifting lug 520 of the pipe pile 500, and in actual setting, they are set according to needs.

[0043] In the specific scheme, the existing structure is taken as an example for illustration, that is, two main lifting lugs 510 are symmetrically arranged on one end of the pipe pile 500 along the circumference thereof, and one turning-over lifting lug 520 is arranged on the other end of the pipe pile 500.

[0044] Correspondingly, in the specific scheme, the first lifting beam 120 is provided with two first lifting points 121, and the third lifting beam 140 is provided with one second lifting point 141; the two first lifting points 121 of the first lifting beam 120 are respectively used for hanging connection with the two main lifting lugs 510 of the pipe pile 500 through the first lifting sling 220, and the second lifting point 141 of the third lifting beam 140 is used for hanging connection with the turning-over lifting lug 520 of the pipe pile 500 through the second lifting sling 230.

[0045] The lengths of the first sling 220 and the second sling 230 are relatively fixed.

[0046] In actual settings, the distance between the two first lifting points 121 on the first lifting beam 120 is matched with the pipe pile 500 that needs to be turned over.

[0047] After the above settings, the turning-over system provided with the turning-over tool can realize the turning-over operation of the pipe pile 500 from the horizontal posture to the upright posture.

[0048] During the operation, the hook part 400 of the hoisting equipment is hung with the lifting point 111 of the lifting beam 110 of the turning-over tool through the lifting sling 210, the first lifting beam 120 of the turning-over tool is hung with the two main lifting lugs 510 of the pipe pile 500 through the two first lifting points 121, the third lifting beam 140 is hung with the turning-over lug 520 of the pipe pile 500 through the second lifting point 141, then the hook part 400 of the hoisting equipment is lifted by controlling the hoisting equipment, the turning-over tool and the pipe pile 500 hung with the turning-over tool are lifted together, when the lifting height is set, the driving part 190 of the turning-over tool is controlled to drive the telescopic structure connected between the second lifting beam 130 and the third lifting beam 140 to drive the third lifting beam 140 to descend, so that the end of the pipe pile 500 hung with the third lifting beam 140 descends, the pipe pile 500 is turned over from the horizontal posture to the upright posture, and the state of the pipe pile 500 turned over to a certain angle can be referred to Figure 4 for understanding.

[0049] The driving part drives the telescopic structure to move until the pipe pile 500 is in the upright posture, during the process, the second lifting beam 130 rotates relative to the lifting beam 110, the first lifting beam 120 moves together with the second lifting beam 130 and can also rotate relative to the second lifting beam 130 to adapt to the turning-over operation of the pipe pile 500.

[0050] Therefore, by using the turning-over tool, only one hoisting equipment is needed to realize the turning-over of the pipe pile 500, and the hoisting equipment only needs to have a hook part 400 hung with the turning-over tool, without the cooperation of the main hook and the auxiliary hook, so that the problem that the distance between the main hook and the auxiliary hook cannot meet the requirements or the stress is not enough in the background art is avoided, and two hoisting equipments are not needed to cooperate, so that the construction difficulty of the turning-over operation of the pipe pile 500 is reduced, the requirement for the hoisting equipment is reduced, and the construction cost is relatively low.

[0051] In a specific scheme, the hinge axis of the second lifting beam 130 and the lifting beam 110 is perpendicular to the length direction of the lifting beam 110, that is Figure 1 As shown in FIG. 1, the lifting beam 110 can be specifically provided as a box beam structure with a certain length, and the bottom of the lifting beam 110 has two oppositely arranged ear plates 113 (indicated in FIG. 1) extending downward. Figure 5The second hoisting beam 130 is hinged to the two ear plates 113 through a hinge shaft, so as to be hinged to the first hoisting beam 120. Figure 1 As shown in the orientation, the hinge axis of the second hoisting beam 130 is perpendicular to the paper plane.

[0052] In the illustrated scheme, the hinge axis of the first hoisting beam 120 and the second hoisting beam 130 is arranged coincident with the hinge axis of the second hoisting beam 130 and the hoisting beam 110, so that the structure is more compact.

[0053] The hinge of the first hoisting beam 120 and the second hoisting beam 130 can also be realized through a hinge shaft.

[0054] It is to be noted here that the first hoisting beam 120 is hinged to the second hoisting beam 130, so that, during the overturning of the pipe pile 500, due to the lowering of the end of the pipe pile 500 connected to the third hoisting beam 140, the second hoisting beam 130 will necessarily adaptively rotate, and the first hoisting beam 120 is hung through the first hoisting point 121 to the pipe pile 500, the hinge of the first hoisting beam 120 and the second hoisting beam 130 makes the first hoisting beam 120 follow to adapt to the change of the position of the pipe pile 500, and the hinge relationship also enables the first hoisting beam 120 to rotate relative to the second hoisting beam 130 to avoid being stuck.

[0055] It is also to be noted that, due to the above connection mode of the first hoisting beam 120 and the second hoisting beam 130, after the overturning tool hangs the pipe pile 500, under the action of gravity of the pipe pile 500, the first hoisting beam 120 and the second hoisting beam 130 will rotate to make the whole structure in a balanced state, so that the center of gravity S of the pipe pile 500 is on the same vertical line with the hinge point of the second hoisting beam 130 and the hoisting beam 110, as shown in the middle of the figure. Figure 1

[0056] Since the hinge axis of the second hoisting beam 130 and the hoisting beam 110 coincides with the hinge axis of the first hoisting beam 120 and the second hoisting beam 130, in order to prevent the second hoisting beam 130 and the first hoisting beam 120 from rotating towards each other and colliding, a collision-preventing support block 310 is fixedly arranged on the side of the first hoisting beam 120 facing the second hoisting beam 130, and / or a collision-preventing support block 310 is fixedly arranged on the side of the second hoisting beam 130 facing the first hoisting beam 120, as shown in the middle of the figure. Figure 5

[0057] In actual arrangement, in addition to the above mode, the hinge axis of the first hoisting beam 120 and the second hoisting beam 130 can also be arranged not coincident with the hinge axis of the second hoisting beam 130 and the hoisting beam 110, but parallel to each other, specifically, an extended hinge ear plate is arranged on the second hoisting beam 130, so that the first hoisting beam 120 and the second hoisting beam 130 are hingedly connected through a hinge shaft passing through the hinge ear plate, so that the first hoisting beam 120 and the second hoisting beam 130 can avoid colliding, and the aforementioned collision-preventing support block is not needed.

[0058] ​​In a specific scheme, the telescopic structure connected between the second hoisting beam 130 and the third hoisting beam 140 is in the form of a pulley block and rope cooperation structure.

[0059] The telescopic structure comprises a first pulley block 150, a second pulley block 160, a rope 170 and a winding drum 180, wherein the first pulley block 150 is installed on the second hoisting beam 130, the second pulley block 160 is installed on the third hoisting beam 140, the rope 170 is wound between the winding drum 180, the first pulley block 150 and the second pulley block 160, and a driving component 190 is capable of driving the winding drum 180 to rotate to retract or release the rope 170, so as to make the third hoisting beam 140 ascend or descend.

[0060] Specifically, the driving component 190 can be an electric motor, and it can also be understood that the driving component 190, the winding drum 180 and the rope 170 are collectively selected in the form of an existing hoist.

[0061] The driving component 190 and the winding drum 180 are specifically installed on the hoisting beam 110, and a mounting seat 112 can be fixedly installed on the hoisting beam 110, and the winding drum 180 and the driving component 190 are specifically installed on the mounting seat 112.

[0062] As shown in the scheme, on the basis that the hoisting beam 110 is provided with two hoisting points 111, the mounting seat 112 is located between the two hoisting points 111, so that the structure of the whole turnover tooling is relatively symmetrical, and the phenomenon of uneven stress of the hook part 400 of the hoisting equipment is avoided.

[0063] One end of the rope 170 is fixed on the winding drum 180, the other end is stretched out of the winding drum 180 after winding on the winding drum 180, and then passes through the first pulley block 150 and the second pulley block 160 in sequence and is fixed on the mounting seat 112; specifically, two oppositely arranged winding drums 180 can be provided, and the rope 170 is stretched out of one winding drum 180, passes through the pulley block, and then winds to the other winding drum 180.

[0064] The winding mode of the rope 170 between the first pulley block 150 and the second pulley block 160 can refer to the common pulley block structure, as long as the third hoisting beam 140 can be driven to ascend or descend by the retraction or release of the rope 170.

[0065] The turnover tooling provided by the present application and the turnover system provided with the same are described in detail above. The principle and implementation mode of the present application are described by applying specific examples in this paper, and the above examples are only used to help understand the method of the present application and its core idea. It should be pointed out that those skilled in the art can make some improvements and modifications to the present application without departing from the principle of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
