[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in view of the shortcomings of the existing technology, a slipway half-ship sliding system with a simple structure is provided, which can effectively improve the utilization rate of the slipway, ensure the continuous loading of ships on the slipway, and ensure that the stern section of the hull can slide safely and reliably.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0007] The present invention is a slipway half-ship sliding system, wherein the ship sliding frame system comprises a plurality of slide plates, a plurality of cross beams, a plurality of first rigid supports, and a plurality of second rigid supports, wherein each slide plate assembly comprises a plurality of slide plates, and the plurality of slide plate assemblies are arranged laterally according to gaps, and the longitudinally adjacent slide plates of each slide plate assembly are fixedly connected by metal wires, and the slide plates in opposite positions in two laterally adjacent groups of slide plate assemblies are fixedly connected laterally by cross beams, an outer sliding limit portion is provided at the inner lower part of the slide plate, and the cross beam is connected to the slide plate by a connecting component, and one side of the stern section of the hull that needs to slide is connected to the slide plate of one slide plate assembly by a first rigid support, and the other side of the stern section of the hull is connected to the slide plate of another slide plate assembly by a second rigid support.

[0008] The crossbeam is supported on multiple sliding tracks, the slide of each slide assembly is supported on a corresponding load-bearing slide, and the outer sliding limit portion of the slide of each slide assembly abuts against the inner side position of the corresponding load-bearing slide.

[0022] L1: effective length inside the slipway gate;

[0023] L2: Captain;

[0024] L3: reserved distance for sliding traction rope;

[0025] L4: total distance between the bow distance and sliding section of the whole ship;

[0026] L5: The distance between the stern cover of the whole ship and the gate;

[0027] The weight calculation of the stern section is: W = W1 + W2 + W3 + W4 + W5;

[0032] W4: outfitting weight;

[0033] W5: Weight of the sliding frame on board.

[0034] The technical solution of the present invention is adopted, and the working principle and beneficial effects are as follows:

[0035] The slipway half-ship sliding system of the present invention, when setting up the structure, makes various components of the ship sliding frame system, the components include a plurality of slides, a plurality of crossbeams, a plurality of first rigid supports, and a plurality of second rigid supports, then combines the various components to form a ship sliding frame system, and then arranges the ship sliding frame system A between the slipway and the stern section of the hull that needs to slide. When assembling the components, each slide board assembly includes a plurality of slide boards, the plurality of slide board assemblies are arranged transversely according to the gap, and the longitudinally adjacent slide boards of each slide board assembly are fixedly connected by metal wires to form a straight-line structure, and the slide boards in opposite positions in the two transversely adjacent groups of slide board assemblies are fixedly connected transversely by crossbeams, the crossbeams and the slide boards are arranged vertically, and an outer sliding limiter is provided at the lower inner side of the slide board, the outer sliding limiter prevents the slide board from detaching from the corresponding load-bearing slide from the side, and the crossbeams and the slide boards are connected by connecting components, and the connecting components realize reliable connection when the crossbeams and the slide boards are connected, and are easy to separate when disassembled. When the ship-borne sliding frame system is connected to the hull, one side of the stern section of the hull that needs to slide is connected to a slide of a slide assembly through a first rigid support, and the other side of the stern section of the hull is connected to a slide of another slide assembly through a second rigid support. In this way, the rigid connection between the ship-borne sliding frame system and the hull can be reliably achieved. The ship-borne sliding frame system can be controlled by a winch towing system to achieve reliable and safe sliding and change its position on the slipway. The principle of the half-ship sliding method adopted by the slipway half-ship sliding system described in the present invention is: Sliding method: The ship-borne sliding frame system is used as a sliding medium, and the main towing system and the auxiliary towing system are controlled by an electrical control system to achieve towing operations, and the half-ship sliding can be reliably completed. Stone of the present invention invents a method for moving a stern half ship in order to improve the utilization rate of the slipway, that is, the whole ship that is launched first is arranged under the slipway near the gate, and the half section of the ship that is launched later is built at the position above the slipway. After the current ship is launched, the slope of the slipway slideway or the traction of the winch cable is used to move the pre-installed stern section from the original construction position to the predetermined installation position at the rear of the slipway. When the sliding frame system slides with the ship, the crossbeam is supported on the sliding track, which can reliably realize both load-bearing and sliding. Similarly, the slides of each slide assembly are respectively supported on the corresponding load-bearing slide, which can reliably realize both load-bearing and position limiting, and can also slide reliably. The beneficial effects of the system of the present invention are: 1. Effectively improve the slipway turnover rate. According to the traditional one-and-a-half shipbuilding method, the average slipway cycle for building a ship is 90 days. After adopting the slipway half-ship sliding method, the slipway cycle can be shortened by 45 days, and the slipway turnover rate is nearly doubled. 2. Make full use of the slipway area, expand the boat installation position, and increase the slipway outfitting workload. Shifting the front and stern half can complete more than 80% of the outfitting work; after the shift, most of the outfitting work of the whole ship can be completed on the slipway, which improves the integrity of the launched ship, resulting in a significant reduction in the dock boat installation workload after the ship is launched, effectively shortening the total construction period of the ship. 3. Maintain the balance of slipway work.By adopting a one-and-a-half-shipbuilding system, various types of work can be arranged to work on two ship positions in a planned and rhythmic manner. This has changed the past phenomenon where various types of work were concentrated on one ship due to the small cabin, and they were crowded and had to wait for work. This has improved the construction quality, ensured safe production, and transferred a large number of water operations to land, improving working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following is a further detailed description of the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various components involved, the function and working principle of each part, etc., through the description of the embodiments with reference to the accompanying drawings:

[0044] As attached Figure 1 -Attached Figure 5As shown, the present invention is a slipway half-ship sliding system, the ship sliding frame system A includes a plurality of slides A1, a plurality of crossbeams A2, a plurality of first rigid supports A3, and a plurality of second rigid supports A4, each slide assembly includes a plurality of slides A5, the plurality of slide assemblies are arranged in a horizontal manner according to the gap, the longitudinally adjacent slides A5 of each slide assembly are fixedly connected by metal wires, the slides A5 in opposite positions in two groups of slide assemblies adjacent in the horizontal direction are fixedly connected in the horizontal direction by the crossbeam A2, the inner lower part of the slide A5 is provided with an outer sliding limiter A6, the crossbeam A4 is connected to the slide A5 by a connecting component A7, one side of the stern section E1 of the hull E to be slidable is connected to the slide A5 of one slide assembly by the first rigid support A3, and the other side of the stern section E1 of the hull E is connected to the slide A5 of another slide assembly by the second rigid support A4. The above structure proposes an improved technical solution to address the deficiencies in the prior art. When setting up the structure, various components of the ship-mounted sliding frame system A are made, including several slide plates A1, several crossbeams A2, several first rigid supports A3, and several second rigid supports A4. Then, the various components are combined to form the ship-mounted sliding frame system A, and then the ship-mounted sliding frame system A is arranged between the slipway and the stern section E1 of the hull that needs to slide. When assembling the components, each slide plate assembly includes multiple slide plates A5, and the multiple slide plate assemblies are arranged horizontally according to the gaps. The slide plates A5 adjacent to each other in the longitudinal direction of each slide plate assembly are fixedly connected by metal wires to form a straight-line structure. The slide plates A5 in opposite positions in two sets of slide plate assemblies adjacent to each other in the horizontal direction are fixedly connected horizontally by crossbeams A2, and the crossbeams A2 are arranged vertically with the slide plates. An outer sliding limiter A6 is provided at the inner lower part of the slide plate A5, and the outer sliding limiter A6 prevents the slide plate from detaching from the corresponding load-bearing slide A8 from the side. The crossbeams A4 and the slide plates A5 are connected by connecting components A7, and the connecting components A7 realize reliable connection when the crossbeams A4 and the slide plates A5 are connected, and are easy to separate when disassembling. When the ship-borne sliding frame system A is connected to the hull, one side of the stern section E1 of the hull E that needs to slide is connected to the slide A5 of a slide assembly through the first rigid support A3, and the other side of the stern section E1 of the hull E is connected to the slide A5 of another slide assembly through the second rigid support A4. In this way, the rigid connection between the ship-borne sliding frame system A and the hull is reliably achieved. The ship-borne sliding frame system A can be controlled by a winch towing system to achieve reliable and safe sliding and change its position on the slipway. The principle of the half-ship sliding method adopted by the slipway half-ship sliding system described in the present invention is: Sliding method: The ship-borne sliding frame system A is used as a sliding medium, and the main towing system and the auxiliary towing system are controlled by an electrical control system to achieve towing operations, and the half-ship sliding is reliably completed.Stone of the present invention invents a method for moving a stern half ship in order to improve the utilization rate of the slipway, that is, the whole ship that is launched first is arranged under the slipway near the gate, and the half section of the ship that is launched later is built at the position above the slipway. After the current ship is launched, the slope of the slipway slideway or the traction of the winch cable is used to move the pre-installed stern section from the original construction position to the predetermined installation position at the rear of the slipway. When the ship sliding frame system A slides, the crossbeam is supported on the sliding track G, which can reliably realize both load-bearing and sliding. Similarly, the slides of each slide assembly are respectively supported on the corresponding load-bearing slide, which can reliably realize both load-bearing and limit, and can also slide reliably. The beneficial effects of the system of the present invention are: 1. Effectively improve the slipway turnover rate. According to the traditional one-and-a-half shipbuilding method, the average slipway cycle for building a ship is 90 days. After adopting the slipway half-ship sliding method, the slipway cycle can be shortened by 45 days, and the slipway turnover rate is nearly doubled. 2. Make full use of the slipway area, expand the boat loading position, and increase the slipway outfitting workload. Shifting the front stern half section can complete more than 80% of the outfitting work; after the shift, most of the outfitting work of the whole ship can be completed on the slipway, which improves the integrity of the launched ship, resulting in a significant reduction in the dock boat loading workload after the ship is launched, and effectively shortens the total construction period of the ship. 3. Maintain the balance of slipway work. With one and a half shipbuilding, each type of work can be arranged to work on two positions in a planned and rhythmic manner, which changes the past phenomenon of various types of work being concentrated on one ship due to the small cabin, crowding each other, and waiting for work, improves the construction quality, ensures safe production, and transfers a large number of water operations in the past to land, improving working conditions. The slipway half-ship sliding system described in the present invention has a simple structure, can effectively improve the utilization rate of the slipway, ensures the continuous loading of ships on the slipway, and ensures that the stern section of the hull can slide safely and reliably.

[0045] The crossbeam A2 is supported on multiple sliding rails G, the slide plate A5 of each slide plate assembly is supported on a corresponding load-bearing slide A8, and the outer sliding limiter A6 of the slide plate A5 of each slide plate assembly abuts against the inner side of the corresponding load-bearing slide A8. In the above structure, the sliding rails G are arranged in multiple lanes, and the multiple sliding rails G are arranged in parallel. The crossbeam is supported on the sliding rails G, and the sliding rails G enable the stern section E1 of the hull E to reliably bear the load and slide reliably. Similarly, the outer sliding limiters A6 of the slide plates on both sides are respectively stuck in the inner side of the corresponding load-bearing slide A8, so as to achieve reliable limitation of the slide plates between the load-bearing slides A8 and ensure that they will not fall off.

[0046] The connecting component A7 includes a crossbeam connecting member A71 and a slide connecting member A72, which are connected by plugging in the vertical direction, and a wedge A1 is inserted in the horizontal direction to limit the crossbeam connecting member A71 and the slide connecting member A72. With the above structure, when the crossbeam and the corresponding slide need to be connected, the crossbeam connecting member A71 and the slide connecting member A72 are connected by plugging in the vertical direction to achieve reliable horizontal limitation, and then the wedge A1 is inserted into the slots on the crossbeam connecting member A71 and the slide connecting member A72 to achieve reliable clamping, ensuring that the crossbeam connecting member A71 and the slide connecting member A72 are reliably positioned in the vertical direction and will not be easily separated.

[0047] The slipway half-ship sliding system also includes a main winch towing system B, an auxiliary winch towing system C, and an electrical control system. The main winch towing system B includes a main winch B1, a main pull winch rope drum B2, a transverse guide wheel B3, a longitudinal guide wheel B4, and an upper pull cable lock B5; the auxiliary winch towing system C includes a reverse pull winch, a reverse pull winch rope drum, a lower pull cable C3, a lifting ring C4, a fixed pulley, and a movable pulley. In the above structure, the main function of the main winch towing system is to generate sufficient traction force, and with the help of the ship-mounted sliding frame system, the acceleration of the hull sliding down is constrained, so that it moves to the predetermined position at a specified speed. Since the stern section E1 of the hull E has a large mass, a large traction force constraint is required, but the pulling force of the main winch cannot be designed too large, so sufficient traction must be obtained by increasing the pulley multiple. However, the pulley multiple should not be too large, otherwise, the steel cable is too long and the rope drum cannot be accommodated, so it is generally only taken 4 to 5 times. Therefore, the main winch must have a large pulling force and a thicker steel cable needs to be used; moreover, due to the large sliding range of the ship and the long towing steel cable, which is generally several hundred meters long, the main winch must use a double-drum winch and be equipped with a cable storage drum. The main function of the auxiliary winch towing system is to increase the sliding force of the ship, overcome the friction resistance of the slideway increased due to some reason, and to pull the ship sliding frame system and the stern section E1 of the hull E to slide down at the specified speed. The traction force required by the auxiliary winch system is much smaller than the traction force of the main winch, and the diameter of the wire rope is also smaller. The electrical control system includes a main winch motor, an auxiliary winch motor, and a cable storage drum motor. The working principle of the electrical control system is to control the towing action of the main winch towing system and the auxiliary main winch towing system through the control of electrical equipment.

[0048] The present invention also relates to a sliding method of a slipway half-ship sliding system with simple steps, which can effectively improve the utilization rate of the slipway, ensure continuous loading of ships on the slipway, and ensure that the stern section of the hull can slide safely and reliably.

Tighten, when one is tightened, the other must be loosened; S4: During the sliding process of the sliding frame system A, when the sliding starts, the main winch towing system B slowly unwinds, and the initial speed is controlled to be low. After the sliding is normal, the intermediate sliding stage gradually increases, and the speed is reduced to a low speed before the sliding reaches the end. Finally, the sliding frame system A is contacted with the anti-skid, and the sliding stern section E stops sliding, and the sliding process ends; S5: After the sliding is completed, the position of the stern section E1 of the hull E is measured and adjusted, and the stern section E1 of the hull E is positioned. At the same time, the rigid support, the middle pier and the side pier are installed, so that the stern section E1 of the hull E falls on the pier wood; the middle pier and the side pier are knocked tight, the traction of the main winch towing system B is tightened, the first rigid support A3 and the second rigid support A4 of the sliding frame system A are removed, the main winch towing system B is loosened, and the auxiliary winch towing system C is used to tow the sliding frame system A out of the bottom of the stern section E1 of the hull E.

[0050] Before using the sliding method of the slipway half-ship sliding system, the whole ship is arranged near the slipway gate, and the stern section E1 is arranged in the remaining space at the upper end of the slipway.

The slide plates A5 in the two groups of slide plates adjacent to each other in the horizontal direction are fixedly connected horizontally by a crossbeam A2, which is arranged vertically with the slide plate. An outer sliding limiter A6 is provided at the inner lower part of the slide plate A5, which prevents the slide plate from detaching from the corresponding bearing slide A8 from the side. The crossbeam A4 is connected to the slide plate A5 by a connecting component A7, which realizes a reliable connection between the crossbeam A4 and the slide plate A5 when connected, and is easy to separate when disassembled.
