Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a ship fixing device and a use method thereof. Background Art

[0002] With the development of globalization and technology, the innovation of shipbuilding technology has gradually become a key research direction. At the same time, in order to achieve the goal of building a strong maritime nation, it is necessary to have powerful ship engineering equipment, so it is inevitable to carry out engineering operations on ships to carry out various construction, repair and modification of ships. However, when building and repairing ships, due to the influence of seawater buoyancy and sea surface wind, the ships will shake, which is not only inconvenient for the work of the staff, but in serious cases, it may also cause equipment and personnel to tip over, causing unnecessary losses.

[0003] In order to solve the above technical problems, application No. 201210313918.2 discloses "a shallow sea area rescue operation vessel and a hull fixing method provided with a pile insertion and extraction device", which has a rack on the outer surface of the pile body, and a lifting mechanism that drives the pile body to move longitudinally and causes the pile body to be inserted into or pulled out of the seabed is engaged with the rack. Although this scheme realizes the insertion of the pile body into the seabed by providing structures such as a rack and a lifting mechanism, its structure is complicated, which leads to a cumbersome process of inserting the pile body into the seabed. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a ship fixing device, which mainly solves the problem that the pile body of the existing ship needs to be inserted into the seabed with the help of a driving mechanism, which leads to a complicated technical problem in the insertion process of the pile body.

[0005] To achieve the above object, the present invention is achieved through the following technical solutions:

[0006] A ship fixing device comprises a support for connecting to the end of a ship hull, the support being fixedly connected to a lifting mechanism and a support platform extending outward, the support platform being provided with a through hole for a column to pass through; the column being configured to be inserted into the seabed by its own gravity, at which time the top of the column is located above the upper surface of the through hole; the column being configured to be pulled out from the seabed by the lifting mechanism.

[0007] Furthermore, a sliding bearing is provided on the inner wall side of the through hole.

[0008] Furthermore, the bottom end of the column is a plug-in end, and the plug-in end is in the shape of an inverted triangle.

[0009] Furthermore, the column is a hollow structure.

[0010] Furthermore, a limit piece is fixedly inserted and passed through the upper end of the column transversely, the limit piece is located above the upper surface of the through hole, and the transverse length of the limit piece is greater than the diameter of the through hole.

[0011] Furthermore, the side wall of the column has a plurality of groups of through-holes arranged evenly and equidistantly in the vertical direction. The through-holes are located below the limiting member for insertion of the plug pin, and the transverse length of the plug pin is greater than the diameter of the through-hole.

[0012] Furthermore, the distance between the limiting member and the uppermost through-and-insertion hole and the distance between two adjacent through-and-insertion holes are both smaller than the lifting stroke of the lifting mechanism.

[0013] Furthermore, the lifting mechanism is connected to the column through a connecting piece.

[0014] Furthermore, there are two ship fixing devices, which are symmetrically arranged at two ends of the hull.

[0015] A method for using the above-mentioned ship fixing device comprises:

[0016] The initial state of the column is: the bottom through-hole of the column is located above the upper surface of the through-hole, and at this time, the plug is inserted into the through-hole;

[0017] When the column needs to be inserted: just pull out the above-mentioned pin and let the column be inserted under its own gravity;

[0018] When the column needs to be pulled out: start the lifting mechanism to drive the column to move upward. When the lifting mechanism is extended upward to the full stroke, the uppermost through-hole is located above the upper surface of the through-hole of the support platform. At this time, the pin needs to be inserted into the through-hole; then retract the lifting mechanism, and then start the lifting mechanism again to extend it to drive the column to continue to move upward; repeat this cycle until the column is completely pulled out from the seabed.

[0019] The above technical solution has the following advantages or beneficial effects:

[0020] In the ship fixing device and the use method thereof and the ship described in the present invention, the column can be directly inserted into the seabed by its own gravity when inserted into the seabed. In this way, not only the ship is fixed, but also the insertion process of the column is simplified, thereby improving the existing ship pile body that needs to rely on a driving mechanism when inserted into the seabed, resulting in a more complicated technical problem in the insertion process of the pile body.

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] Please refer to the attached Figure 1 To Attachment Figure 2 The first embodiment of the present invention provides a ship fixing device, which is suitable for fixing ships in shallow waters, and includes a support 2 connected to the end of the ship hull 1, preferably a detachable connection, so as to adjust the position of the ship fixing device. The support 2 is fixedly connected with a lifting mechanism 3 and a support platform 4 extending outward, and the support platform 4 is provided with a through hole 41, and the through hole 41 is for the column 5 to pass through; the column 5 is configured to be inserted by its own gravity when inserted into the seabed, and at this time, the top of the column 5 is located above the upper surface of the through hole 41, so as to prepare for the subsequent extraction of the column 5. The column 5 is configured to be pulled out by the lifting mechanism 3 when being pulled out of the seabed, specifically: the lifting mechanism 3 is connected to the column 5 through a connecting piece 8 to drive the column 5 to be pulled out of the seabed. It can be understood that in this embodiment, when the column 5 is inserted into the seabed, it can be directly inserted into the seabed only by its own gravity. In this way, not only the fixation of the ship is achieved, but also the insertion process of the column 5 is simplified, thereby improving the existing problem that the pile body of the ship needs to be inserted into the seabed with the help of a driving mechanism, resulting in a more complicated technical problem in the insertion process of the pile body.

[0029] Preferably, there are two ship fixing devices, which are symmetrically arranged at two ends of the hull 1 so that the overall force of the hull 1 is balanced.

[0030] Please refer to the attached Figure 1 To Attachment Figure 2 In one preferred embodiment, a sliding bearing is provided on the inner wall side of the through hole 41 to reduce friction resistance, so that the insertion and extraction process of the column 5 is smoother and the energy consumption is lower. The bottom end of the column 5 is a plug-in end 51, and the plug-in end 51 is in the shape of an inverted triangle, so that the column 5 can be inserted into the seabed more quickly. However, those skilled in the art should understand that in other embodiments, the shape of the plug-in end 51 can also be a quadrilateral or a pentagon, etc., and the present invention does not make specific limitations.

[0031] Please refer to the attached Figure 1 To Attachment Figure 2 In one preferred embodiment, a hoisting hole 52 is provided on the top of the column 5 to facilitate hoisting of the column 5. The column 5 is a hollow structure, so that the overall mass of the column 5 is relatively light, which is convenient for transportation of the column 5.

[0032] Please refer to the attached Figure 1 To Attachment Figure 2 In one preferred embodiment, the upper end of the column 5 is laterally penetrated by a fixed insert limiting member 6, and the limiting member 6 is located above the upper surface of the through hole 41, and the lateral length of the limiting member 6 is greater than the diameter of the through hole 41 to prevent the column 5 from completely passing through the through hole 41 and failing to fix it; at the same time, when pulling out the column 5, the connecting member 8 connected to the lifting mechanism 3 should be wrapped around the side wall of the column 5 and located below the limiting member 6. At this time, the limiting member 6 not only facilitates the pulling out of the column 5, but also prevents the connecting member 8 from falling off the column 5.

[0033] Please refer to the attached Figure 1 To Attachment Figure 2 In one preferred embodiment, the lifting mechanism 3 is preferably a hydraulic telescopic cylinder, one end of the connecting member 8 is fixedly connected to the support 2 to stabilize it, the other end is wrapped around the side wall of the column 5 to connect with the column 5, and the middle part is connected to the end of the telescopic rod of the hydraulic telescopic cylinder so that the column 5 can be driven to move upward when the telescopic rod is extended. However, those skilled in the art should understand that in other embodiments, the lifting mechanism 3 can also be other driving mechanisms that can play the same role as this embodiment.

[0034] Please refer to the attached Figure 1 To Attachment Figure 2In one preferred embodiment, the side wall of the column 5 is equidistantly and neatly arranged with a plurality of through-plug holes 53 in the vertical direction. The through-plug holes 53 are located below the stopper 6 for the insertion of the plug pin 7, and the transverse length of the plug pin 7 is greater than the diameter of the through hole 41, so that the column 5 can be completely pulled out from the seabed later. At the same time, the spacing between the stopper 6 and the topmost through-plug hole 53 and the spacing between two adjacent through-plug holes 53 are both smaller than the lifting stroke of the lifting mechanism 3 (i.e., the extension stroke of the telescopic rod of the hydraulic telescopic cylinder). It can be understood that in this embodiment, when the column 5 is pulled out and each time the telescopic rod is fully extended, a plurality of through-plug holes 53 will be located above the upper surface of the through hole 41 from top to bottom in sequence, so that the plug pin 7 can be inserted into the corresponding through-plug hole 53 to prevent the column 5 from falling.

[0035] Please refer to the attached Figure 1 To Attachment Figure 3 A second embodiment of the present invention provides a method for using a ship fixing device, comprising:

[0036] The initial state of the column 5 is: the bottom through-hole 53 of the column 5 is located above the upper surface of the through-hole 41, and at this time, the plug 7 is inserted into the through-hole 53;

[0037] When the column 5 needs to be inserted, just pull out the above-mentioned plug 7 and let the column 5 be inserted under its own gravity;

[0038] When the column 5 needs to be pulled out: start the lifting mechanism 3 to drive the column 5 to move upward. When the lifting mechanism 3 is extended upward to the full stroke, the uppermost through-hole 53 is located above the upper surface of the through-hole 41 of the support platform 4. At this time, the pin 7 needs to be inserted into the through-hole 53; then retract the lifting mechanism 3, and then start the lifting mechanism 3 again to extend it to drive the column 5 to continue to move upward; repeat this cycle until the column 5 is completely pulled out from the seabed. Specifically, when pulling out the column 5, the connecting piece 8 should be tightly wound around the side wall of the column 5 and located below the limiter 6. At this time, the hydraulic telescopic cylinder is started to extend the telescopic rod of the hydraulic telescopic cylinder upward and drive the column 5 to move upward through the connecting piece 8. Since the spacing between the limiter 6 and the uppermost through-plug hole 53 and the two adjacent through-plug holes 53 is smaller than the extension stroke of the telescopic rod, when the telescopic rod is extended upward to the full stroke, at this time, the uppermost through-plug hole 53 is located above the upper surface of the through-hole 41 of the support platform 4, and the latch 7 needs to be inserted into the through-plug hole 5 3; then retract the telescopic rod, and re-tighten the connecting piece 8 on the lower side wall of the column 5, start the hydraulic telescopic cylinder again, and let the telescopic rod of the hydraulic telescopic cylinder extend upward to continue to drive the column 5 to move upward. The plug 7 can be unplugged at any time during the process of re-tightening the connecting piece 8 on the side wall of the column 5 and extending the telescopic rod upward, ensuring that the plug 7 can be unplugged without affecting the next insertion of the column 5 into the seabed; this cycle is repeated until the column 5 is completely pulled out from the seabed, and finally the plug 7 is plugged into the through-plug hole 53 at the bottom of the column 5 to return to the initial state of the column 5. When the column 5 is inserted into the seabed, the through-plug hole 53 can also allow seawater to enter the interior of the column 5, making the insertion of the column 5 into the seabed more secure.
