[0014] Next, with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shapes, structures, mutual positions and connection relationships of the various components involved, the functions and working principles of each part, etc., will be further described in detail.
[0015] As Figure 1-8As shown in the figure, this shallow-beach walking engineering ship includes: a triangular main hull 1 with three independent pile-standing points; each pile-standing point includes two main piles, namely pile leg A 3 and pile leg B 5, which are driven by a pile driving system to stand alternately to achieve the advancement of the ship; each pile-standing point is equipped with an independent single-point rotation system 6, and the single-point rotation system 6 includes a rotating gear track 14, a single-point rotation drive motor 15 and a pile driving platform 21, which are used to adjust the direction of the pile leg guide rail to achieve 360° advancement angle control; a pile shoe 2, which is connected to the end of the main pile and contacts the mud surface. The three independent pile-standing points are respectively arranged at the three corners of the triangular main hull 1, and a single-point rotation outer cabin wall 12 is arranged outside the single-point rotation system 6. As Figure 7 shown, a pile driving platform 21 is arranged outside pile leg A 3 and pile leg B 5, and a pile driving main body 22 is arranged at the bottom of the pile driving platform 21. A plurality of lifting pile driving motors 19 are evenly distributed on the pile driving platform 21. The lifting pile driving motors 19 are connected to driving gears, and the driving gears are clamped into the pile leg holes 4 on the pile legs. A plurality of pile leg holes 4 are evenly arranged vertically on the pile legs, and the positions of the pile leg holes 4 are correspondingly arranged with the teeth of driving gear 1.
[0016] As Figure 6 、 7 shown, the pile driving system includes a pile driving motor 16 and a pile driving limit guide rail 18. There are two pile driving limit guide rails 18, which are arranged between the pile driving platform 21 and the pile driving main body 22. Pile driving teeth 17 are arranged on the pile driving limit guide rail 18, and a pile driving motor 16 is arranged on the pile driving main body 22. The pile driving motor 16 is connected to driving gear 2, and driving gear 2 meshes with the pile driving teeth 17. The pile driving motor 16 drives the pile leg to move on the pile driving limit guide rail 18, and the alternate movement stroke of the pile leg is controlled by the pile driving limit guide rail 18. An inner roller 23 is arranged inside the pile driving main body 22. When pile leg A 3 and pile leg B 5 move up and down, their outer surfaces contact the inner roller 23, which is used to reduce the rotational friction force and ensure the rotational accuracy.
[0017] As Figure 6 shown, the gear track 14 is circular. A plurality of single-point rotation drive motors 15 are arranged outside the gear track 14. Gears are connected to the single-point rotation drive motors 15, and the gears mesh with the outer teeth 20 outside the gear track 14. The single-point rotation drive motors 15 are fixed on the triangular main hull 1.
[0018] As Figure 1 shown, a boom 7, a boom shelf 8, a crane barrel 9, a crane main body 10 and a derrick 11 are equipped at the top of the triangular main hull 1. The boom 7, the boom shelf 8, the crane barrel 9 and the crane main body 10 form a crane main body for hoisting. The crane and the derrick 11 are used for construction in shallow beach areas or sunken ship salvage operations. The adjustable area of the pile shoe 2 ranges from 10 to 30 square meters to adapt to different muddy shallow beach areas. As Figure 2 、5 As shown, a watertight compartment 13 is provided in the triangular main hull 1 , and the provision of the watertight compartment 13 is beneficial to increasing the floating performance of the triangular main hull 1 .
[0019] When in use, the pile driving motor 16 rotates and drives the driving gear 2 to move the pile legs horizontally, the pile lifting driving motor 19 moves the pile legs vertically, and the single-point rotation driving motor 15 drives the gear track 14 to realize the steering of the engineering vessel.
[0020] A method for using a shoal walking engineering vessel comprises the following steps: (1) If Figure 9 As shown, the vessel is first towed to the safe water depth closest to the construction shoal area, and the tugboat unties the towline and assists the vessel in dropping anchor and deploying the anchor. (2) If Figure 10 As shown, after the ship's position is stable, the lifting motor drive system of the three sets of A pile legs 3 of the ship is started to stand the three A piles. At the same time, the depth of the ballast pile legs is adjusted to make each pile reach the load depth. Pay attention to the ship's posture to ensure the stability of the standing piles and ensure the safety of the ship. Each time the piles are stood, it is necessary to confirm that the standing piles are stable and safe. (3) If Figure 11 As shown, after the three A piles have finished standing, the A pile driving motor (16) is turned on. At this time, the entire ship uses the three A piles as the fulcrum, and the entire ship moves forward slowly under the drive of the driving motor until the A and B pile main platforms come into contact and the ship stops moving. (4) If Figure 12 As shown, three sets of B pile lifting drive motors 19 are started to complete the standing of three B piles and ensure that they reach the predetermined depth and stand steadily; (5) If Figure 13 As shown, at this time, the three sets of A pile lifting drive motors 19 are started, and the three A piles are slowly pulled out. During the A pile pulling process, the three B piles and the ship's posture are observed until the A pile pulling is completed; (6) If Figure 14 As shown, the three A pile driving motors 16 are started to move the A piles forward to the end of the track; (7) If Figure 15 As shown, three sets of A pile lifting driving motors 19 are started to complete the A pile standing in place; (8) If Figure 16 As shown, the three sets of B pile lifting pile driving motors 19 are started to complete the B pile pulling. At this time, steps 2-8 are a complete cycle. The purpose of ship travel can be achieved by repeating the operation. This cycle is a unidirectional travel process for the ship. (9) Figure 17 As shown, if the forward angle needs to be adjusted while the ship is moving, the three sets of A or B piles are moved to the rotation center positions of the three single-point rotation systems respectively; As shown in Figure 18 Figure (10), at this time, start the single-point rotation drive motors 15 of the three sets of single-point rotation systems 6. The three sets of single-point rotation systems 6 rotate around the row pile platform respectively, so that the direction of the pile leg guide rail is aligned with the predetermined positioning direction of the shoal. After the rotation of the three sets of single-point rotation systems 6 is completed, repeating the above processes 2-8 can complete the arrival at the established shallow water area; (11) After the construction is completed, the ship also operates according to the processes 2-10 to complete the withdrawal.
[0021] This shoal walking engineering ship operates several power motor drive systems through the ship control system to enable the ship to freely switch between shallow and deep water areas for work. It is especially suitable for shallow water soft geological areas with a water depth of 0-10 meters, not affected by surging waves and beach-breaking waves, and the operation weather window is not restricted.
[0022] In terms of walking, this engineering ship is solved by using an independent three-set tripod-type double-pile alternating standing pile system. In terms of the traveling direction, it uses three independent single-point rotation systems to adjust the traveling angle of the ship by changing the direction of the guide rail. The three-point tripod-type standing pile technology, each point has two piles, and the two piles are driven alternately by a motor to achieve the forward and backward movement of the ship with the standing pile as the fulcrum. At the same time, each point is equipped with an independent rotation system as a whole, and by adjusting the angle of the pile guide rail at each point, the forward direction of the pile can reach 360°.
[0023] Compared with conventional ships, the advantages of using this shoal walking engineering ship include: breaking through the technical bottleneck that large ships cannot enter the shoal for construction, not being restricted by the water depth in shallow water areas, not being restricted by environmental factors such as surging waves and weather in the construction environment, greatly reducing the weather standby ratio, shortening the construction period, saving costs, the construction ship does not need to drop anchors and lay out the field, having no risk of grounding and touching the bottom, and greatly improving safety.
[0024] The present invention has been described exemplarily above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
