Description

Technical Field

[0001] The invention relates to the technical field of marine equipment, and in particular to a vertical positioning device for a ship to be stably stopped on water. Background Art

[0002] Ships are ideal water emergency carriers, but when floods occur, the water flow in the river is turbulent, so ships as carriers need stable positioning capabilities. General ship positioning piles are driven by hydraulic cylinders for lifting and lowering. In order to meet different water depths, the cylinder needs to be set with a sufficient working stroke, which is costly. In addition, when the positioning piles are lifted, the movable rod of the cylinder needs to be retracted into the cylinder body. The pollutants carried by the outer wall of the movable rod may enter the cylinder and have an adverse effect on the cylinder work. Not only that, in turbulent rivers, the water flow is surging, and the general hull positioning piles only rely on one-time positioning of the pile body, which cannot adapt well to the impact and influence of water flow in different directions on the hull. In the prior art, a Chinese patent with the authorization announcement number CN116118941B discloses a vertical positioning device for a ship to be stably stopped on water, comprising a positioning pile, wherein the positioning pile is movably connected to the hull in the horizontal direction and slidably connected in the vertical direction through a slide, wherein the positioning pile is hollow, a movable pulley is arranged inside the positioning pile, the slide is used for unwinding a reel of a sling, a rotating sleeve, an induction plate, a spiral rod and a spiral sleeve are arranged at the bottom of the positioning pile, the rotating sleeve is rotatably connected to the positioning pile, and an induction plate is arranged on the rotating sleeve, and the induction plate can drive the spiral rod to rotate and move downward;

[0003] The positioning piles of the above-mentioned ship's vertical positioning device for steady stopping on the water can be driven into the bottom of the water by their own gravity, and then the piles can be driven deep by the pressure cylinder to achieve stable and fixed piles. After one positioning, the effect of the water flow on the induction plate can be used to make the spiral rod at the bottom of the positioning pile continue to be driven deeper. However, during the pile setting process, there may be relatively hard rocks under the soil layer, and it is difficult for the device to determine the depth of the rock. When the oil cylinder forcibly applies pressure to the drill bit, the drill bit is easily damaged, or the drill bit may slip, causing the device to tilt and unable to be positioned in the vertical direction. With the combined effect of the turbulent water flow, the hull may capsize. Summary of the invention

[0036] Embodiment 1: Figures 1 to 6As shown, the present application is a vertical positioning device for a ship to be stably stopped on water, including a positioning pile 300, wherein the positioning pile 300 is movably connected to the hull 100 in the horizontal direction through a slide 200, and the positioning pile 300 is slidably connected to the slide 200 in the vertical direction, the positioning pile 300 is hollow, and a movable pulley 312 is arranged inside the positioning pile 300, and a synchronous platform 500 and an unwinder 400 for unwinding a lifting rope 410 are arranged on the slide 200, and the synchronous platform 500 is connected to the slide 200 through a synchronous oil cylinder 530; an adjusting pulley 510 and a steering pulley 520 are arranged on the synchronous platform 500, and the lifting rope 410 is unwound from the unwinder 400. The locating pile 300 is wound up by the adjusting pulley 510 after passing through the steering pulley 520 and the movable pulley 312 in sequence; the synchronization platform 500 is provided with a pressure cylinder 600 above the positioning pile 300, and the pressure piston 311 inside the pressure cylinder 600 is fixedly connected to the pressure rod 310, and the pressure rod 310 passes through the top of the positioning pile 300 and extends to the inside of the positioning pile 300, and a force-bearing member for contacting the bottom of the pressure rod 310 is provided above the movable pulley 312; a coupling shaft is provided at the shaft end of the adjusting pulley 510, and a synchronous gear is fixedly sleeved on the coupling shaft, and the synchronous gear is meshed with the synchronous rack, and one end of the synchronous rack is fixedly connected to the pressure rod 310.

[0037] The bottom of the positioning pile 300 is provided with a positioning assembly 700, which includes a rotating sleeve 710, an induction sleeve 720, a drilling and pressure platform 730 and a spring drill 740; the rotating sleeve 710 is a vertically arranged cylindrical body, and a transfer hole 713 is opened at the top center thereof, such as Figure 6 The bottom of the pressure rod 310 is rotatably connected to the rotating sleeve 710 through the adapter hole 713; Figure 2 and Figure 3 The rotating sleeve 710 is provided with an annular matching groove in the middle, and the induction sleeve 720 is sleeved in the matching groove. The induction sleeve 720 is an annular cylindrical shape with upper and lower openings. A plurality of induction plates 721 are vertically arranged on the outer surface of the induction sleeve 720. The plurality of induction plates 721 are rectangular plates uniformly distributed around the outer annular surface of the induction sleeve 720. The drilling and pressing platform 730 is arranged in the induction sleeve 720, and the spring drill 740 is fixed at the bottom of the drilling and pressing platform 730. The spring drill 740 is a conical spring with the tip downward as a whole. Figure 5 A plurality of vertically arranged ratchet teeth 714 are provided in the matching groove of the rotating sleeve 710, one side of the tooth surface of the ratchet teeth 714 is a vertical surface, and the other side is an inclined surface; a groove is provided on the inner ring surface of the sensing sleeve 720, and a limiting tooth 722 is connected inside the groove by a spring, and the tooth surface of the limiting tooth 722 cooperates with the ratchet teeth 714, so that the sensing sleeve 720 can only rotate in one direction, and the rotation direction of the sensing sleeve 720 is the spiral direction of the spring drill 740.

[0038] The working process of the vertical positioning device for a ship that stops steadily on water in this embodiment is as follows:

[0039] S1: The unwinding shaft of the unwinder 400 rotates in the opposite direction to release the suspension rope 410, and the positioning pile 300 moves downward. At the same time, the synchronous oil cylinder 530 contracts, and the synchronous platform 500 and the positioning pile 300 move downward synchronously until the bottom of the positioning pile 300 penetrates the limit position of the bottom of the water, and the unwinder 400 is closed. At this time, the limit clamp limits the adjustment pulley 510.

[0040] S2: When pressing the pile, the limit clamp corresponding to the adjustment pulley 510 is released, the upper space of the pressure piston 311 enters the pressure cylinder 600 to press the positioning pile 300, the pressure piston 311 and the pressure rod 310 move downward, and the pressure rod 310 presses the positioning pile 300; at this time, the synchronous rack moves downward synchronously, and the synchronous rack drives the gear to rotate, so that the adjustment pulley 510 rotates forward, and the adjustment pulley 510 releases the line to ensure that the positioning pile 300 has a margin for being pressed downward by the positioning pile 300;

[0041] When the pressure piston 311 of the pressure cylinder 600 moves to the lower limit position, the synchronous cylinder 530 contracts by oil discharge, the synchronous platform 500 descends, the pressure cylinder 600 follows the synchronous platform 500 to descend, and the pressure piston 311 moves relatively to the upper limit position of the pressure cylinder 600. The pressure cylinder 600 can continue to apply pressure. During this process, the adjustment pulley 510 rotates in the opposite direction, and the adjustment pulley 510 performs a line-retracting action to prevent the suspension rope 410 from being loosened.

[0042] S3: As the positioning pile 300 is pressed downward, the lower part of the spring drill 740 is inserted into the underwater foundation, and the spring drill 740 as a whole is deformed by the pressure; when the water flow acts on the sensing plate 721 and causes the sensing sleeve 720 to rotate forward, the rotating sleeve 710 drives the rotating sleeve 710, and the rotating sleeve 710 drives the spring drill 740 to rotate forward, so that the spring drill 740 rotates and penetrates the foundation; when the water flow causes the sensing sleeve 720 to rotate in the opposite direction, the ratchet 714 on the rotating sleeve 710 is not pushed by the limiting teeth 722, so that the spring drill 740 will not rotate in the opposite direction.

[0043] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0044] In this embodiment, an induction sleeve 720, a rotating sleeve 710 and a spring drill 740 are arranged, and the three cooperate with each other. When the spring drill 740 is compressed, it produces elastic deformation. Driven by the water flow, the spring drill 740 rotates and continues to drill deep into the underwater foundation, and spirals in the foundation without being easily loosened, thereby solving the technical problem of the positioning device in the prior art that the drill bit is easily damaged or slipped when encountering rocks during the bottom drill bit drilling process, and achieving the technical effect that the drill bit can shrink and deform after touching the rock and the positioning is more stable.

[0045] Embodiment 2: Considering that in the above embodiment 1, in order to ensure the strength of the spring drill 740, it is necessary to prevent the reaction force of the spring drill 740 from being too high after the positioning pile 300 is directly pressed down, causing the hull to initially produce unstable shaking, it is necessary to improve the device so that the spring drill 740 can be inserted into the foundation smoothly and avoid the hull from being subjected to a strong reaction force, such as Figures 7 to 9 As shown, the specific structure is as follows:

[0046] A sliding platform 732 is fixed on the top of the drilling and pressing platform 730, and a positioning groove 731 is provided on one side of the sliding platform 732; a sliding cavity 712 is provided inside the rotating sleeve 710, and the sliding platform 732 is slidably connected to the sliding cavity 712. The bottom of the sliding cavity 712 is open, and the opening size matches the drilling and pressing platform 730. When the sliding platform 732 slides up and down in the sliding cavity 712, the drilling and pressing platform 730 and the spring drill 740 can be synchronously retracted into or extended from the sliding cavity 712; a positioning protrusion 711 is fixed on one side of the inner wall of the sliding cavity 712, and the positioning protrusion 711 cooperates with the positioning groove 731 to control the rotation of the sliding platform 732, and when the rotating sleeve 710 rotates, the sliding platform 732 can drive the drilling and pressing platform 730 and the spring drill 740 to rotate synchronously.

[0047] The lower part of the positioning pile 300 is coaxially fixed with a pressure cylinder 320 above the rotating sleeve 710. The pressure cylinder 320 is cylindrical and has a pump liquid chamber 321 inside. A pressure plate 323 is coaxially slidably connected in the pump liquid chamber 321. A compression spring 322 is fixed between the upper end surface of the pressure plate 323 and the top of the pump liquid chamber 321. The compression spring 322 is used to pull the pressure plate 323 up to the top of the pump liquid chamber 321. When the pressure cylinder 600 drives the pressure rod 310 to move downward, the movable pulley 312 at the bottom of the pressure rod 310 resists downward. The upper end surface of the liquid pressure plate 323 is pushed to move downward to the bottom of the pump liquid chamber 321. The positioning pile 300 at the bottom of the pressurizing cylinder 320 is partially provided with a liquid through hole 325, and the liquid through hole 325 is used to connect the pump liquid chamber 321 and the sliding chamber 712. A one-way liquid inlet pipe 324 is connected to one side of the bottom of the pump liquid chamber 321. A one-way valve is provided inside the one-way liquid inlet pipe 324. The end of the one-way liquid inlet pipe 324 away from the pump liquid chamber 321 is connected to the external space of the pressurizing cylinder 320, so as to allow the water outside the pressurizing cylinder 320 to enter the pump liquid chamber 321.

[0048] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0049] In this embodiment, a pressurizing cylinder 320, a sliding chamber 712 and a sliding platform 732 are provided. When the positioning pile 300 is pressed down, the sliding platform 732 first slides upward to the top of the sliding chamber 712, so that the upper half of the spring drill 740 is retracted into the sliding chamber 712. When the pressure rod 310 repeatedly moves up and down under the action of the pressure cylinder 600, the pressure plate 323 is repeatedly pumped into the pump chamber 321 through the one-way liquid inlet pipe 324 by the pressure rod 310 and the pressure spring 322. At the same time, with the pressure of the liquid pressure plate 323, the water in the pump liquid chamber 321 is squeezed into the sliding chamber 712, so that the spring drill 740 is subjected to downward liquid pressure, and the internal hydraulic pressure of the sliding chamber 712 is kept in a balanced state under the elastic reaction force of the spring drill 740. As the spring drill 740 continues to rotate and insert into the foundation, the reaction force of the spring drill 740 is gradually eliminated, thereby avoiding the initial elastic reaction force of the spring drill 740 being too high, causing unstable shaking of the hull at the initial stage.

[0050] Embodiment 3: In order to further improve the working efficiency of the positioning assembly 700 and improve the stability and firmness of the spring drill 740 after entering the foundation, it is necessary to improve the device, such as Figures 10 to 14 As shown, the specific structure is as follows:

[0051] The outer ring side and the inner ring side of the spring drill 740 are both fixed with a spiral pressing sheet 750, the spiral pressing sheet 750 is a spiral sheet elastic body, and the spiral pressing sheet 750 is arranged along the length direction of the spring drill 740, and the length of the spiral pressing sheet 750 is equal to that of the spring drill 740;

[0052] like Fig.14 The spiral pressing plate 750 includes an upper pressing plate 751 and a lower pressing plate 752. The upper pressing plate 751 is fixed to the upper end surface of the lower pressing plate 752. The cross-section of the upper pressing plate 751 is triangular. The upper pressing plate 751 forms a slope extending outward from the spring drill above the lower pressing plate 752. The lower pressing plate 752 is a stainless steel metal sheet, and the upper pressing plate 751 is made of elastic rubber.

[0053] A liquid outlet groove 733 is provided inside the drilling and pressing platform 730, and a liquid outlet hole 734 is provided at the bottom of the liquid outlet groove 733; a liquid spray channel 741 is provided inside the spring drill 740, and one end of the liquid spray channel 741 passes through the bottom end of the spring drill 740, and the other end is upwardly connected to the bottom of the liquid outlet hole 734; a one-way valve is fixedly connected to the top of the liquid outlet hole 734, and the one-way valve is used to allow the liquid in the liquid outlet groove 733 to flow out to the liquid spray channel 741.

[0054] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0055] In this embodiment, the liquid injection channel 741 is provided. When the bottom of the spring drill 740 is inserted into the underwater foundation, the end of the liquid injection channel 741 is blocked. When the pressure plate 323 applies hydraulic pressure to the inside of the sliding chamber 712, as the water pressure increases, water is ejected from the liquid injection channel 741, so that the spring drill 740 moves downward more smoothly. Secondly, a spiral pressing sheet 750 is provided. When the spring drill 740 is pressed downward as a whole, the spiral pressing sheet 750 compacts the loose part of the foundation. At the same time, after the spiral pressing sheet 750 is excavated with the spring drill 740, under the action of the upper pressing sheet 751, the spring drill 740 is more stable underwater and is not easy to be pulled out, which can better stabilize the hull 100.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
