Description

Technical Field

[0001] This utility model relates to the field of ship conversion technology, and in particular to a support fixture for the main bow section of an old ship. Background Technology

[0002] In large-scale ship conversion projects, it is often necessary to cut off and set aside a portion of the hull structure, and then reassemble the set-off portion after the conversion of other areas is completed. For the cut-off area, if the shape is large, reasonable support fixtures must be designed. This patent addresses the support fixture structure involved in the reassembly of an old ship's bow section after it has been cut off. This design can simultaneously meet the process requirements of the old bow section in the initial cutting state, the resting state, and the final closing and positioning state, taking into account factors such as strength, stability, and construction.

[0003] When using the above-mentioned technology, the following technical problems were found in the existing technology: The existing technology adopts separate designs for anti-tilting supports and adjustment and positioning supports, which are complex in structure and cumbersome in operation. Moreover, the existing technology has a fixed support position for the old bow section, and cannot flexibly adjust the support spacing, angle or height according to the actual structural differences on both sides of the old bow section (such as asymmetry of the line shape, local damage), center of gravity shift or construction conditions (such as the tilt angle when it is laid down), resulting in poor support adaptability and possible uneven local stress or stability hazards. To this end, we designed a support fixture for the old bow section of a ship to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a support fixture for the main bow section of a ship to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A support fixture for the main bow section of a ship includes a base plate. Electric guide rails are fixed to both sides of the top of the base plate. A movable plate and a movable dock block are slidably connected to the top of the electric guide rails. Two support rollers are mounted on the top of the movable plate. Inclined positioning rollers are rotatably connected to both sides of the support rollers. A linkage plate is fixed to the end of the two inclined positioning rollers away from the support rollers. An adjustment and clamping mechanism for the inclined positioning rollers is provided on both sides of the top of the movable plate. The clamping mechanism includes a guide seat, a lead screw, an adjusting seat, and a lifting rod. Guide seats are fixed to both sides of the top of the movable plate. An adjusting seat is slidably connected to the inner side of the guide seat. A lifting rod is rotatably connected to the top of the adjusting seat, and the top of the lifting rod is rotatably connected to the linkage plate.

[0006] The guide seat has a lead screw rotatably connected to its inner side, and the lead screw is threadedly connected to the adjusting seat on its outer side.

[0007] One end of the lead screw passes through the guide seat and is fixed with a handle.

[0008] The guide seat has several limiting holes on one side, and the adjusting seat has a limiting pin slidably connected to one side, with one end of the limiting pin slidably connected to the corresponding limiting hole.

[0009] A spring is sleeved on the outer side of the limiting pin, one end of the spring is fixed to the limiting pin, and the other end of the spring is fixed to the adjusting seat.

[0010] The movable plate has a support plate fixed at one end of its top, a support column fixedly connected to the inner side of the support plate, and an arc-shaped plate fixed to the outer side of the support column.

[0011] The inner side of the arc-shaped plate is fixed with a fitting pad.

[0012] An adjustment mechanism is provided between the movable plate and the movable dock. The adjustment mechanism includes a support column, a drive block, a hydraulic rod, and a linkage rod. Linkage rods are rotatably connected to both sides of one end of the movable dock. The drive block is rotatably connected to the end of the linkage rod away from the movable dock. A hydraulic rod is assembled at one end of the bottom of the movable plate, and the output end of the hydraulic rod is fixed to the drive block.

[0013] The movable dock has support columns fixed on both sides at one end, and the outer side of the support columns is slidably connected to the movable plate.

[0014] The top of the movable dock is equipped with a buffer pad.

[0015] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses the arc plate and the fitting pad to accurately fit the deflection of the bottom end of the old bow, combined with the multi-point support system formed by the support rollers and movable dock piers, which can evenly distribute the load of the old bow; at the same time, the inclined positioning rollers on both sides achieve stable positioning through the clamping mechanism, and with the locking structure of the limiting pin and the limiting hole, it can effectively prevent the old bow from tilting or falling over, thus ensuring the stability and safety of the support process as a whole, and avoiding structural damage caused by excessive force at a single point; The adjusting seat driven by the screw can flexibly change the clamping angle of the tilting positioning roller; in the adjusting mechanism, the hydraulic rod drives the linkage rod to precisely adjust the distance between the moving plate and the movable dock, ensuring that the two are at the optimal support point; in addition, the overall movement function realized by the electric guide rail enables the tooling to quickly adapt to the support position requirements under different working conditions, greatly improving the versatility of the equipment. The overall displacement of the support structure is achieved by using electric guide rails, and the driving method of the handle and hydraulic rod reduces the intensity of manual operation. At the same time, details such as the pre-tightening force design of the spring on the limit pin and the buffer pad on the top of the movable dock ensure the stability and reliability of the clamping state, and reduce the rigid damage to the old bow during the support process, thus achieving an effective balance between ease of operation and safety of use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] As shown in the background technology: Existing technologies employ separate designs for anti-tilting supports and adjustment positioning supports, resulting in complex structures and cumbersome operations. Furthermore, existing technologies fix the support positions of the old bow section, making it impossible to flexibly adjust the support spacing, angle, or height based on actual structural differences on both sides of the old bow section (such as asymmetrical alignment or local damage), center of gravity shift, or construction conditions (such as the tilt angle during placement). This leads to poor support adaptability and may result in uneven local stress or potential stability issues.

[0022] Example 1 Please see Figure 1-8 This utility model provides a technical solution: a support fixture for the main section of an old ship's bow, including a base plate 1, electric guide rails 2 fixed on both sides of the top of the base plate 1, a movable plate 3 and a movable dock 5 slidably connected to the top of the electric guide rails 2, two support rollers 9 mounted on the top of the movable plate 3, inclined positioning rollers 10 rotatably connected to both sides of the support rollers 9, a linkage plate 11 fixed to the end of the two inclined positioning rollers 10 away from the support rollers 9, and a clamping mechanism for adjusting the inclined positioning rollers 10 provided on both sides of the top of the movable plate 3, the clamping mechanism including a guide seat 13, a lead screw 15, an adjusting seat 16 and a lifting rod 12, a guide seat 13 fixed on both sides of the top of the movable plate 3, an adjusting seat 16 slidably connected to the inner side of the guide seat 13, a lifting rod 12 rotatably connected to the top of the adjusting seat 16, and the top of the lifting rod 12 rotatably connected to the linkage plate 11; When it is necessary to disassemble and support the old bow section, the old bow section is lifted by a crane, and then the movable plate 3 and movable dock 5 are moved to directly below the old bow section. The movable plate 3 drives the support roller 9 and the arc plate 6 to support the bottom of the old bow section. The inner side of the arc plate 6 effectively fits and supports the deflection of the bottom of the old bow section. The support roller 9 and the movable dock 5 effectively support the center of gravity of the old bow section, so as to effectively support the old bow section. The movable plate 3 and the movable dock 5 effectively move the old bow section along the guide of the electric guide rail 2. Then, by activating the clamping mechanism, the inclined positioning roller 10 is driven to clamp the two sides of the bottom end of the old bow, thereby preventing the old bow from tilting and improving the stability of the old bow support. A lead screw 15 is rotatably connected to the inner side of the guide seat 13, and the outer side of the lead screw 15 is threadedly connected to the adjusting seat 16. One end of the lead screw 15 passes through the guide seat 13 and is fixed with a handle 14. Rotating the handle 14 drives the lead screw 15 to rotate, and the lead screw 15 drives the adjusting seat 16 to apply pressure to the lifting rod 12 along the guide seat 13, so that the lifting rod 12 lifts the linkage plate 11, and the adjusting seat 16 drives the lifting rod 12 to lift and tilt the linkage plate 11, thereby facilitating the clamping of both sides of the bottom end of the old bow, so as to effectively clamp and limit the old bow, and ensure the support and positioning of the disassembled old bow; A number of limiting holes 18 are provided on one side inside the guide seat 13, and a limiting pin 17 is slidably connected to one side of the adjusting seat 16. One end of the limiting pin 17 is slidably connected to the corresponding limiting hole 18. When the rotating handle 14 drives the lead screw 15 to support the adjusting seat 16, lifting rod 12 and tilting positioning roller 10 on both sides of the old bow, at this time, to prevent the tilting positioning roller 10 from becoming loose, it is then engaged with the limiting hole 18 on one side of the guide seat 13 by the limiting pin 17, thereby ensuring the stability of the tilting positioning roller 10 supporting both sides of the bottom end of the old bow. A spring 20 is sleeved on the outside of the limiting pin 17. One end of the spring 20 is fixed to the limiting pin 17, and the other end of the spring 20 is fixed to the adjusting seat 16. The elasticity of the spring 20 effectively ensures that the limiting pin 17 is engaged with the corresponding limiting hole 18, so that the adjusting seat 16 can drive the lifting rod 12 and the inclined positioning roller 10 to clamp the width of both sides of the bow. At this time, the limiting pin 17 is limited according to the inclined clamping angle driven by the adjusting seat 16 to ensure the stability of the inclined angle of the inclined positioning roller 10. A support plate 4 is fixed to one end of the top of the movable plate 3. A support column 8 is fixedly connected to the inner side of the support plate 4. An arc plate 6 is fixed to the outer side of the support column 8. An adhesive pad is fixed to the inner side of the arc plate 6. The inner side of the arc plate 6 effectively fits with the deflection of the bottom of the old bow. The adhesive pad effectively improves the anti-slip and support effect between the old bow and the arc plate 6.

[0023] Example 2 Reference Figures 8-10 A support fixture for the main section of an old ship's bow, wherein an adjustment mechanism is provided between a movable plate 3 and a movable dock 5, the adjustment mechanism including a support column 8, a drive block 21, a hydraulic rod 7 and a linkage rod 19, the two sides of one end of the movable dock 5 are rotatably connected to the linkage rod 19, the end of the linkage rod 19 away from the movable dock 5 is rotatably connected to the drive block 21, and one end of the bottom of the movable plate 3 is equipped with a hydraulic rod 7, the output end of the hydraulic rod 7 is fixed to the drive block 21; By activating the hydraulic rod 7, the drive block 21 and the linkage rod 19 are moved towards the moving plate 3. As a result, the linkage rod 19 drives the movable dock 5 to move along the guide between the support column 8 and the moving plate 3, thereby shortening the distance between the moving plate 3 and the movable dock 5. This facilitates support based on the length of the bottom of the old bow, effectively placing the moving plate 3 and the movable dock 5 at the optimal support point of the old bow, thus ensuring the support effect of the old bow. Both sides of one end of the movable dock 5 are fixed with support columns 8. The outer side of the support column 8 is slidably connected to the movable plate 3. The top of the movable dock 5 is equipped with a buffer pad.

[0024] The usage process of the support fixture for the old bow section of a ship provided by this utility model is as follows: After the old bow section is lifted by a crane, the movable plate 3 and the movable dock 5 are moved along the electric guide rail 2 to directly below the old bow section. The support roller 9 at the top of the movable plate 3, the arc-shaped plate 6, and the movable dock 5 form a multi-point support structure. The inner fitting pad of the arc-shaped plate 6 fits against the deflection of the bottom end of the old bow section, and the support roller 9 and the movable dock 5 jointly support the center of gravity of the old bow section, achieving stable lifting. Then, the clamping mechanism is used to limit and fix the two sides of the old bow. Rotating the handle 14 drives the lead screw 15 to rotate, causing the adjusting seat 16 to slide along the guide seat 13, which in turn pushes the lifting rod 12 to lift the linkage plate 11, driving the inclined positioning rollers 10 on both sides to move closer to the old bow and clamp. After the adjustment is completed, the limiting pin 17 is inserted into the limiting hole 18 of the guide seat 13 under the elastic force of the spring 20, locking the position of the adjusting seat 16, ensuring that the clamping angle of the inclined positioning rollers 10 is stable, and preventing the old bow from tilting. Finally, based on the required length of the old bow section, the distance between the movable plate 3 and the movable dock 5 is adjusted using the adjustment mechanism. The hydraulic rod 7 is activated to move the drive block 21, which in turn drives the linkage rod 19 to pull the movable dock 5 along the support column 8, placing both at the optimal support point of the old bow section and optimizing the support effect.

[0025] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
