Description

Technical Field

[0001] The invention relates to the field of underwater engineering construction, and in particular to a horizontality control device and a control method thereof during the sinking of an underwater pile barrel. Background Art

[0002] Offshore wind turbines usually use large steel pipe piles as pile foundations. Due to the particularity of some geology, the stability of the foundation cannot be guaranteed by using only a single pile foundation, so the pile-barrel composite foundation has emerged. The pile-barrel composite foundation mainly involves placing a large-diameter composite barrel under the outer jacket of the steel pipe pile, and using a negative pressure machine to sink the composite barrel below the mud surface to provide support for the steel pipe pile.

[0003] When the steel pipe pile is driven to the predetermined depth according to the design specifications, the composite barrel body should be immediately inserted into the steel pipe pile, and the composite barrel body should be slowly sunk. The sinking process of the barrel body is relatively long, and most of the time it is below the water surface. During construction, the horizontality of the top surface of the barrel body should be ensured to be within a certain range. In the prior art, the barrel body is usually hoisted by ropes, and the horizontality of the barrel body is directly set outside the steel pipe pile after hoisting and adjustment.

[0004] With regard to the above-mentioned prior art, it is difficult to adjust the horizontality of the composite barrel after the barrel body is hoisted outside the steel pipe pile, which is not convenient for ensuring the stability of the position of the barrel body when it is sleeved on the steel pipe pile.

In order to further ensure the stability of the rotating worm wheel during rotation, the adjustment seat 23 is provided with a receiving groove 29 which is arranged to penetrate along the vertical direction. The two ends of the adjusting worm wheel 25 respectively abut against the two groove walls directly opposite to the receiving groove 29, so that the receiving groove 29 plays a further limiting role on the position of the adjusting worm wheel 25 during rotation.

[0056] Reference Figure 7When the first motor 21 and the second motor 22 drive their own output ends to rotate respectively, the connecting seat 20 rotates around the axis of the output end of the first motor 21 and the axis of the adjusting worm wheel 25 respectively, that is, the connecting seat 20 is horizontally rotated around the x-axis direction and the y-axis direction.

Among them, the limiting semi-ring 34 is fixedly installed on the hanging plate 2, one end of the limiting semi-ring 34 is fixedly installed on the hanging plate 2, and the other end is provided with an arc-shaped limiting slide 37. The shape of the limiting rod 35 is similar to the limiting slide 37 is adapted and slidably fitted in the limiting slide groove 37, one end of the limiting spring 36 is fixedly set on the groove wall of the limiting slide groove 37, and the other end is fixedly set on the limiting rod 35. The limiting rod 35 is pressed against the side wall of the hanger plate 2 under the elastic force of the limiting spring 36. When the annular sling 33 is located in the area surrounded by the limiting semi-ring 34, the limiting rod 35 and the hanger plate 2, the position of the annular sling 33 is limited, thereby ensuring the stability of the position of the annular sling 33.

[0059] Continue to refer to Figure 7 and Figure 8 In order to facilitate the application of force to move the limit rod 35, a sliding groove 38 extending in the vertical direction is provided on the top of the limit rod 35, and a control rod 39 is slidably fitted in the sliding groove 38. A control groove 40 connected to the limit groove 37 and extending circumferentially around its own axis is provided on the top of the limit semi-ring 34. The control rod 39 is slidably fitted in the control groove 40. When the control rod 39 slides in the control groove 40, the limit rod 35 moves in the limit groove 37 in the direction close to or away from the hanging plate 2. A positioning block 41 is fixedly connected to the groove wall of the sliding groove 38. A positioning groove 42 extending in the direction of its own axis is provided on the outer peripheral surface of the control rod 39. Both ends of the positioning groove 42 in the length direction are closed. The positioning block 41 is slidably fitted in the positioning groove 42, so that the control rod 39 is not easy to escape from the sliding groove 38, which is convenient for stably realizing the driving of the limit rod 35.

[0060] Continue to refer to Figure 7 and Figure 8 The side of the limiting semi-ring 34 away from the notch of the control slide 40 is provided with a fixing hole 43 and a positioning hole 44 which are plugged with the control rod 39. The fixing hole 43 and the positioning hole 44 are distributed circumferentially along the axis of the limiting semi-ring 34. When the control rod 39 is plugged with the positioning hole 44, the limiting rod 35 is received in the limiting slide 37, which is conducive to ensuring the limiting effect of the limiting rod 35 received in the limiting slide 37. When the control rod 39 is plugged with the fixing hole 43, one end of the limiting rod 35 away from the notch of the limiting slide 37 abuts against the lifting ring 50, which is conducive to further ensuring the stability of the position of the annular sling 33 when limiting. The control rod 39 is fixed with a control ring 45, so that the staff can apply force to realize the vertical and horizontal movement of the control rod 39.

[0061] The implementation principle of the embodiment of the present application is as follows: when the barrel body of the composite barrel needs to be inserted into the steel pipe pile, the hanging plate 2 is first hoisted, and the hanging plate 2 is used to hoist the sling body through the connecting seat 20 and each annular sling 33. The bottom of the sling body is used to stably hoist the barrel body through the wire rope 32. During the barrel body hoisting process, the inclination sensor 1 detects the inclination of the composite barrel in the x-axis and y-axis directions. When the composite barrel tilts in the x-axis direction or the y-axis direction, the first motor 21 and the second motor 22 drive the rotation of their own output ends to rotate the connecting seat 20 around the x-axis direction and the y-axis direction, and then adjust the horizontality of the composite barrel through the annular sling 33 and the sling body, which is beneficial to ensure the stability of the position of the barrel body when it is sleeved on the steel pipe pile. The setting of the reinforcement rod is beneficial to ensure the overall structural stability of the sling body, and facilitates the connecting parts at the connection of each fixed beam 121 to achieve stable bearing on the barrel body.

[0062] The embodiment of the present application also discloses a method for controlling the horizontality of an underwater pile barrel during its penetration. The method comprises the above-mentioned device for controlling the horizontality of an underwater pile barrel during its penetration, and specifically comprises the following steps:

[0063] S1, after each annular sling 33 is sequentially connected to the connection seat 20 and the sling body, and the wire rope 32 is connected to the connection piece and the composite barrel, the composite barrel is hoisted through the hoisting plate 2.

[0064] S2, after the composite barrel is hoisted and mounted on the steel pipe pile, the inclination sensor 1 is used to detect the inclination of the composite barrel in the x-axis and y-axis directions.

[0065] S3, according to the detection data of the inclination sensor 1, the connecting seat 20 is driven to rotate around the x-axis direction and the y-axis direction through the horizontal adjustment mechanism to achieve micro-leveling of the composite barrel.

[0066] S4, when the detection data of the inclination sensor 1 is within the preset range, the composite barrel is slowly hoisted to the preset installation position.

[0067] The implementation principle of a method for controlling the horizontality of an underwater pile barrel during penetration in an embodiment of the present application is as follows: during the lifting process of the barrel body, the inclination sensor 1 realizes inclination detection of the composite barrel in the x-axis and y-axis directions. When the composite barrel is tilted in the x-axis direction or the y-axis direction, the first motor 21 and the second motor 22 drive the rotation of their own output ends to rotate the connecting seat 20 around the x-axis direction and the y-axis direction, and then the horizontality of the composite barrel is adjusted through the annular sling 33 and the sling body, which is beneficial to ensure the stability of the position of the barrel body when it is sleeved on the steel pipe pile. The setting of the reinforcement rod is beneficial to ensure the overall structural stability of the sling body, and facilitates the connecting parts at the connection of each fixed beam 121 to achieve stable bearing on the barrel body.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
