Abstract
Description
Technical Field
[0001] The invention belongs to the field of marine ship design and construction, and in particular relates to an insertable elastic bow support module. Background Art
[0002] When the ship is launched on the slide, when the ship reaches the stern floating state, the fulcrum reaction force at the bow fulcrum is very large, which can easily cause structural instability and generate a lot of structural repair work, resulting in a significant increase in costs and affecting the ship delivery plan.
[0003] In order to achieve the requirement of rapidity, the outer plate of the bow area of the ship usually presents a V-shaped thin line. When launching, a center slideway needs to be set on the slipway. The effective contact area between the pads above the slide at the bow fulcrum and the outer bottom plate of the hull is very small. Therefore, a bow bracket device with the same shape as the hull outer plate is placed on the center slideway, such as Figure 1 In the existing design, the bow support device is a fixed bow fulcrum device. Each ship needs to make a support according to the shape of the ship. When the same type of ship is discarded after use, the bow support is a heavy structure and needs to be transported to the slipway by a crane, which is difficult to position. After launching, it needs to be recovered from the water, and the salvage and production costs are high, and the utilization rate is low. Summary of the invention
[0004] In order to solve the above problems, the present invention provides a plug-in elastic bow support module, aiming to improve the utilization rate of the bow support module and reduce the actual ship construction cost. The technical solution adopted is: A plug-in elastic head support module has a rectangular iron frame. Both ends and the top of the iron frame are open structures. The iron frame consists of a frame body and support bars fixed on the frame body. Multiple lateral support bars are vertically arranged on both sides of the frame body, and multiple bottom support bars are horizontally arranged at the bottom of the frame body.
[0005] A combined wood module is fixed inside the iron frame. A V-shaped groove is set in the center of the combined wood module. Flat irons are pressed on the edges of both sides of the top of the combined wood module. Vertical bolts pass through the flat irons from top to bottom to fix the combined wood module. The combined wood module is composed of multiple layers of sub-wooden blocks stacked from bottom to top. The bottom layer is an ordinary wood block, and the rest are spring wood blocks. The spring wood block is composed of an external square sleeve and a solid wood block inserted into the square sleeve. The square sleeve is slidably connected to the solid wood block. The side of the spring wood block close to the V-shaped groove is tilted, and the tilt angle is A, 45° <A<70°。
[0006] The iron frame is symmetrically provided with connecting flat irons and elastic buckles on both sides, and the connecting flat irons and elastic buckles on each side are respectively located at the two ends of one side, and the connecting flat irons are hinged with the lateral support bars. A slideway is provided on the slipway, and the bow support module is fixed in the bow fulcrum area of the slideway.
[0007] The above-mentioned plug-in elastic head support module further has a height difference between the lowest point and the highest point of the groove of at least 500 mm.
[0008] The above-mentioned plug-in elastic head support module, further, has a frame body made of angle steel.
[0009] The above-mentioned plug-in elastic head support module further has a plurality of bottom support bars arranged at equal intervals, and a plurality of lateral support bars arranged at equal intervals.
[0010] The above-mentioned plug-in elastic head support module further has a rubber sheet laid on the inner surface of the groove.
[0011] The above-mentioned plug-in elastic head support module further has sliding grooves on both sides of the sleeve, and the solid wooden block has sliding blocks that match the sliding grooves.
[0012] The above-mentioned plug-in elastic head support module, further, the iron frame is fixed on the slideway by a slide plate, and the width of the slide plate is the same as the width of the iron frame.
[0013] The above-mentioned plug-in elastic head support module, further, has transverse bolts fixed on the sides of the combined wood module, and the transverse bolts pass through the lateral support strips to fix the combined wood module.
[0014] The present invention uses the principle of mechanics to design an elastic bow support module that can be spliced and plugged in. It can be adjusted according to the length and fatness of the ship, and can be used by multiple ships. It solves the problem of large stress on the bow support point during launching, and the high cost of salvaging and manufacturing. At the same time, it can improve the utilization rate of the bow support module, reduce the actual ship construction cost, and improve the safety of ship launching. The principle of splicing is used to solve the problem of overweight of the bow bracket and simplify the installation process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0016] The present invention will be further described in conjunction with the accompanying drawings.
[0017] like Figure 2 , 3 As shown in Figure 4, a plug-in elastic head support module includes a rectangular iron frame, the two ends and the top of the frame are open structures, frame support bars are arranged on both sides and the bottom of the frame, and the height of the frame is the same along the length direction of the frame. A plurality of spring wooden blocks are embedded in the frame, and the plurality of spring wooden blocks are arranged in sequence along the height direction of the frame. The combined spring wooden blocks have downwardly concave grooves, and the grooves are V-shaped. The bottoms of the V-shaped grooves are located on the same horizontal line, and the height difference between the lowest point and the highest point of the groove is at least 500mm.
[0018] There are two rows of flat irons on the top of the frame, which press the top of the wooden block. Vertical bolts pass through the flat irons and the wooden block from the top of the wooden block. There are transverse bolts on both sides of the bottom of the frame. The transverse bolts are close to the bottom of the wooden block and pass through the frame and the wooden block from the outside of the wooden block to fix the wooden block in the frame.
[0019] The iron frame is filled with a combined wood module. The center of the combined wood module is provided with a downward concave V-shaped groove. Flat irons are pressed on the edges of the top and sides of the combined wood module. Vertical bolts pass through the flat irons from top to bottom to fix the combined wood module. The combined wood module is composed of multiple layers of sub-wooden blocks stacked from bottom to top. The bottom layer is ordinary wood blocks, and the rest are spring wood blocks, such as Figure 5 As shown, the spring block is composed of an external square sleeve 16 and a solid wood block 17 inserted into the square sleeve. The square sleeve is slidably connected to the solid wood block. The spring block is inclined near the V-shaped groove, and the inclination angle is A, 45° <A<70°。
[0020] The outer sleeve structure is a wooden structure with a certain thickness, which plays a fixing role in combination with the vertical bolts. The rubber sheet 12 installed on the inclined edge protects the outer plate of the hull and can greatly increase the contact area between the wooden module and the outer plate.
[0021] The bottom wooden block is a non-elastic wooden block, which has a frictional resistance to the upper wooden block. There is a groove in the middle, which serves as a vertical support for the bottom of the ship. The top elastic wooden block is fixed by the top flat iron of the iron frame and the flat irons on both sides. The bottom elastic wooden block is fixed by the flat irons on the front, back and both sides of the iron frame. The top and bottom wooden blocks tightly connect the middle wooden block, and there is friction between them to limit the displacement. The middle elastic wooden block is fixed by the flat irons on the front, back and both sides. All elastic wooden blocks have built-in springs, which can be compressed independently according to the pressure they are subjected to, but the maximum compression displacement is the same. The initial state of the combined spring wooden module is 11, and the maximum compression displacement is 13.
[0022] Before the combined spring wood module is made, an iron frame is made of angle steel and flat iron. The length and width of the iron frame are the same as those of the skateboard. The frame body is made of angle steel, and the frame support bars are made of flat iron. The frame support bars are divided into lateral support bars and bottom support bars. The lateral support bars are located on both sides of the frame, and the bottom support bars are located at the bottom of the frame. The lateral support bars are arranged vertically along the height direction, and the bottom support bars are arranged horizontally along the width direction. After the iron frame is made, several pieces of wood are placed in the iron frame along the width direction of the iron frame, and the wood is tightened and fixed in the longitudinal, transverse and vertical directions by through bolts.
[0023] The combined spring wood module has a groove in the middle of the wood to maximize the contact area with the hull outer plate. From the cross-section, the height difference between the lowest and highest points of the groove is at least 500mm, which is used to better digest and absorb the reaction force of the bow fulcrum.
[0024] A rotating ring 15 and a connecting flat iron 8 are installed on the vertical flat irons at the front of the two sides of the rectangular iron frame. The connecting flat iron 8 can rotate on the rotating ring 15 and then can be connected to the adjacent iron frame. An elastic buckle 14 is installed on the vertical flat irons at the rear of the two sides of the frame, which can be connected to the adjacent iron frame. The spring buckle is normally in a state of springing up, and it drops down after being pressed, and it can spring up automatically after being pressed down.
[0025] The combined structure of rectangular iron frame and spring wood block can be used in connection or separately. The number of elastic bow modules can be selected according to different ship types and sizes, and the combined structure is lighter than the existing structure (the existing structure is a solid structure), has strong compatibility, can be customized according to the ship type and tonnage, and can eliminate the transportation process, which is convenient for positioning.
[0026] For ships with a thin bow structure, three slideways are usually used for launching. High piers need to be set on both sides of the slideway to squeeze the side to increase the contact area, which is wasteful. This patent can only set the middle slideway, turning the three slideways in the bow area into one, saving costs and simplifying the process.
[0027] The traditional two slideways for launching ships with pointed and thin lines on the outer plate cannot meet the structural weight of the pointed and thin bow area. Therefore, a central slideway must be added between the original two slideways. The wooden module is placed in the bow fulcrum area of this central slideway, such as Figure 8 As shown in the figure, a temporary slideway is added to the slipway center, where Figure 8 The strong force area of the slipway is also given, and the bow fulcrum reaction area of the ship launched from the slipway must fall within this strong force area. Fig. 9 This is a side view of the ship being built on the slipway. Fig.10 It is a schematic diagram of the stern float when the ship is launched. The appropriate tide height is selected through calculation before launching. When the stern of the ship enters the water to a certain depth, the stern begins to float, and the bow fulcrum entering the strong force area is immediately subjected to force. The wooden module located on the center slide can well bear the bow fulcrum reaction force generated by the stern float.
