Description

Technical Field

[0001] The present invention relates to the technical field of ship support, in particular to a telescopic movable support tool. Background Art

[0002] The vessel, the "Nora," undertook a bulbous bow conversion. The conversion required a lengthwise cut at FR256-200, and a height cut from 12,900 meters below the baseline. Approximately 200 tons of tonnage was removed. A new, energy-efficient bulbous bow section, weighing approximately 160 tons, would be installed in the corresponding location. The entire conversion process would be carried out in the dock. Due to the large size of the original vessel, the upper portion of the cut, which involved the entire forecastle section, weighing over 300 tons, posed a risk of sagging and deformation if appropriate support measures were not implemented before the bulbous bow section was removed. Based on stress analysis and strength calculations, the original plan was to reinforce the bow with two supports on each side. These reinforcements would be constructed from three 325-diameter steel pipes, weighing approximately 6 tons. However, due to the vessel's large bow flare, the supports were located within the flare, making it impossible for the dock crane to directly lift the tooling into place. Furthermore, the 2-ton winch's pulling force was insufficient to meet the lifting requirements.

[0003] The main problem with the original tooling was that it was too heavy, and the dock crane could not directly lift it into place, while the existing winch could not meet the requirements. The contact area on the dock deck was small, the standing stability was insufficient, there were great safety risks in on-site installation, and the flexibility during use was low.

[0004] Therefore, we propose a telescopic movable support tooling to solve the above problems. Summary of the Invention

[0023] The embodiment of the present application provides a telescopic movable support tooling, which changes the support tooling from a "column" type to a "tower" type, thereby increasing the contact area with the ground and lowering the center of gravity, thereby increasing the stability of the support tooling and further improving the safety of construction. The position of the end support head can be readjusted through the power mechanism of the support assembly, and the height position and deflection angle of the support head can be adjusted, thereby solving the technical problems mentioned in the background technology.

[0024] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: Example 1: See also Figure 1-10 The present invention provides a technical solution: a telescopic movable support tooling, including a base 1, an intermediate slide bar 2 is slidably provided on the base 1, the intermediate slide bar 2 and the base 1 are fixedly connected by two sets of limit pins 8, a support assembly 3 is provided on the top of the intermediate slide bar 2, a support leg 5 is rotatably provided on the base 1, and the support leg 5 is provided with three groups, the support assembly 3 includes a first hydraulic cylinder 31, one end of the push rod of the first hydraulic cylinder 31 is fixedly connected to the adjusting rod 32, one end of the adjusting rod 32 is welded and fixed with a U-shaped seat 33, and an adjusting rod 33 is rotatably provided on the U-shaped seat 33. Block 34, the adjusting block 34 is driven by the second hydraulic cylinder 35, a connecting frame 36 is welded and fixed on one side of the adjusting rod 32, a second connecting seat 37 is welded and fixed on the connecting frame 36, a connecting head 38 is fixed on one end of the push rod of the second hydraulic cylinder 35, the cylinder body of the second hydraulic cylinder 35 and the second connecting seat 37 are rotatably connected through a rotating shaft, a third connecting seat 39 is welded and fixed on one side of the adjusting block 34, the connecting head 38 and the third connecting seat 39 are rotatably connected through a rotating shaft, and the support assembly 3 and the intermediate slide bar 2 are fixedly connected through a fixed seat 310.

[0025] The main structural form of the overall support tooling is composed of three inclined tubes and one straight tube. The straight tube is designed to be telescopic up and down to achieve the effect of quick installation. The three inclined tubes provide stable support and are supported by three sets of legs 5 in contact with the ground. The support tooling is changed from a "column" type to a "tower" type, which increases the contact area with the ground and lowers the center of gravity, thereby increasing the stability of the support tooling and improving the safety of construction. The middle slide bar 2 can slide relative to the base 1. By adjusting the extended length of the middle slide bar 2 relative to the base 1, the overall height of the support tooling can be flexibly adjusted. Due to the high height of the support tooling, a horizontal manufacturing solution can be adopted. The middle slide bar 2 is manufactured to the minimum requirements to facilitate transportation and installation. Compared with the original tooling, the weight of the tooling is reduced, which effectively saves the cost of using auxiliary materials.

[0026] An adjustable support assembly 3 is added to the top of the middle slide bar 2. The position of the end support head is fine-tuned through the power mechanism of the support assembly 3 so that the support head can be accurately supported. The power mechanism of the support assembly 3 is composed of a first hydraulic cylinder 31 and a second hydraulic cylinder 35. The first hydraulic cylinder 31 and the second hydraulic cylinder 35 are both connected to the ground hydraulic pump group through oil pipes. The height position of the ground hydraulic pump group is set at a suitable position. The ground hydraulic pump group consists of multiple hydraulic pumps and related components, such as motors, control valves, filters, etc. The function of the ground hydraulic pump group is to provide stable and controllable hydraulic energy for the hydraulic system, driving the first hydraulic cylinder 31 and the second hydraulic cylinder 35 to complete specific actions.

[0027] like Figure 6 、 Figure 7 and Figure 8 As shown, when the first hydraulic cylinder 31 is working, it drives the adjusting rod 32 at one end thereof to slide axially along the middle slide bar 2, thereby adjusting the extended length of the adjusting rod 32 relative to the middle slide bar 2, and the adjusting rod 32 drives the end support head to move synchronously, thereby fine-tuning the height position of the support head. In actual use, the deflection angle of the end support head can be flexibly adjusted according to the support requirements through the second hydraulic cylinder 35. When the second hydraulic cylinder 35 is working, it drives the connecting head 38 at one end thereof to move, and the connecting head 38 drives the third connecting seat 39 to move. The third connecting seat 39 drives the adjusting block 34 to rotate relative to the U-shaped seat 33, and the U-shaped seat 33 drives the support head, thereby adjusting the deflection angle of the support head. The deflection angle of the support head is controlled by the telescopic stroke of the push rod of the second hydraulic cylinder 35. By fine-tuning the position of the end support head, the support head can be close to the position to be supported by the ship, thereby achieving stable support.

[0028] Installation method of support tooling: After the ship enters the dock, the approximate range of the support position is surveyed on the dock deck, and the support tooling is placed as close to the designated position by using the dock crane. The middle slide bar 2 is pulled by the winch, and the support tooling is towed to the designated position by a hand winch. The three sets of legs 5 of the support tooling are then rigidly fixed to the dock deck, and the middle slide bar 2 is lifted to a certain height by the winch. The height position of the support assembly 3 is adjusted so that the top support assembly 3 reaches near the outer plate. After the height position of the middle slide bar 2 is determined, two sets of limit pins 8 are used to connect the base 1 and the middle slide bar 2. Finally, the position of the end support head is fine-tuned by the first hydraulic cylinder 31 and the second hydraulic cylinder 35 of the support assembly 3 so that the support head can accurately support the ship.

[0029] In some examples, the intermediate slide bar 2 is configured as a hollow structure, the fixing seat 310 is welded and fixed in the hollow chamber of the intermediate slide bar 2, the first hydraulic cylinder 31 is installed and fixed on the fixing seat 310, the adjusting rod 32 is slidingly connected to the intermediate slide bar 2, and the first hydraulic cylinder 31 is hidden in the intermediate slide bar 2. When the first hydraulic cylinder 31 is working, it drives the adjusting rod 32 at one end thereof to slide axially along the intermediate slide bar 2, adjusts the extended length of the adjusting rod 32 relative to the intermediate slide bar 2, and then adjusts the height position of the end support head again.

[0030] In some examples, the base 1 is provided with multiple groups of first plug holes 11 , the middle slide bar 2 is provided with multiple groups of second plug holes 21 , and the limiting pin 8 passes through the first plug holes 11 of the base 1 and the second plug holes 21 of the middle slide bar 2 .

[0031] When lifting the middle slide bar 2 by the winch, after lifting, ensure that the first plug hole 11 of the base 1 is aligned with the second plug hole 21 at a certain point on the middle slide bar 2, and then use two sets of limit pins 8 to pass through the first plug hole 11 and the second plug hole 21 to achieve a fixed connection between the base 1 and the middle slide bar 2. When disassembling, pull out the limit pin 8 to release the fixation between the base 1 and the middle slide bar 2, and the middle slide bar 2 is retracted into the steel pipe 4 at the lower end of the base 1 to achieve folding, which is convenient for storage and transportation.

[0032] In some examples, hanging parts 23 are welded and fixed on both sides of the middle slide bar 2, and the hanging parts 23 form a hanging position, which is conducive to the hanging of the overall supporting tooling.

[0033] In some examples, a slot 22 is provided on one side of the middle slide bar 2, and the slot 22 is located on one side of the first hydraulic cylinder 31. The slot 22 forms an oil pipe connection position. The oil pipe can extend into the hollow chamber of the middle slide bar 2 through the slot 22 and be connected to the first hydraulic cylinder 31 to provide hydraulic energy for the first hydraulic cylinder 31.

[0034] By adopting the above technical solutions: The main structural form of the overall support tooling consists of three inclined tubes and one straight tube. The straight tube is designed to be telescopic up and down to achieve the effect of rapid installation. The support tooling is changed from a "column" type to a "tower" type, which increases the contact area with the ground and lowers the center of gravity, thereby increasing the stability of the support tooling and improving the safety of construction.

[0035] An adjustable support assembly 3 is added to the top of the middle slide bar 2, and the position of the end support head can be readjusted through the power mechanism of the support assembly 3, and the height position and deflection angle of the support head can be adjusted so that the support head can provide accurate support, improve the support stability, and at the same time improve the flexibility of the support tooling during use.

[0036] Example 2: Based on Example 1, this example introduces the specific structure of the support leg 5 in a telescopic movable support tooling. A first connecting seat 12 is welded and fixed on the side of the base 1. Three groups of first connecting seats 12 are provided, and the three groups of first connecting seats 12 are evenly spaced along the circumferential direction of the base 1.

[0037] In some examples, a connecting plate 51 is welded and fixed to one end of the supporting leg 5 , and the first connecting seat 12 of the base 1 and the connecting plate 51 of the supporting leg 5 are fixedly connected by a locking bolt 7 .

[0038] The three groups of first connecting seats 12 correspond to the three groups of legs 5 respectively. When the locking bolts 7 are loosened, the legs 5 can rotate relative to the first connecting seats 12, that is, the deflection angle of the legs 5 relative to the base 1 can be adjusted. By adjusting the deflection angles of the three groups of legs 5, the opening angles of the three groups of legs 5 can be adjusted. The opening angles of the three groups of legs 5 can be adjusted accordingly according to actual usage requirements to achieve stable support and meet different support requirements. By increasing the opening angles of the legs 5, the center of gravity can be further lowered, the stability of the supporting tooling can be increased, and the flexibility during use can be improved. After the opening angles of the three groups of legs 5 are adjusted, the locking bolts 7 are tightened again.

[0039] In some examples, a steel pipe 4 is welded and fixed to the lower end of the base 1, and the steel pipe 4 is connected to the support legs 5 through a central stabilization component 6. The central stabilization component 6 connects the three groups of support legs 5 and transfers the load, thereby improving the stability, load-bearing capacity and anti-overturning ability of the support tooling, and enhancing the overall support tooling's ability to resist lateral forces.

[0040] In some examples, the central stabilization component 6 includes a sleeve 61 and a connecting rod 62. The sleeve 61 is sleeved on the steel pipe 4, and the steel pipe 4 and the sleeve 61 are slidingly connected. A fifth connecting seat 63 is welded and fixed on the side of the sleeve 61. There are three groups of fifth connecting seats 63, and the three groups of fifth connecting seats 63 are evenly distributed along the circumferential direction of the sleeve 61.

[0041] In some examples, a fourth connecting seat 52 is welded and fixed to the support leg 5, one end of the connecting rod 62 is rotatably connected to the fourth connecting seat 52 via a rotating shaft, and the other end of the connecting rod 62 is rotatably connected to the fifth connecting seat 63 via a rotating shaft.

[0042] like Figure 9 and Figure 10 As shown, the three groups of legs 5 can be opened synchronously to a certain angle. At the same time, the sliding sleeve 61 of the central stabilizing component 6 slides accordingly along the steel pipe 4, one end of the connecting rod 62 rotates a certain angle relative to the fifth connecting seat 63, and the other end of the connecting rod 62 rotates a certain angle relative to the fourth connecting seat 52. The opening and closing angles of the legs 5 supporting the tooling are adjustable to adapt to different terrains. The legs 5 are foldable, which is convenient for the storage and transportation of the overall supporting tooling.

[0043] By adopting the above technical solutions: When the locking bolt 7 is loosened, the three groups of legs 5 can all rotate relative to the first connecting seat 12. The opening angles of the three groups of legs 5 of the supporting tooling can be adjusted accordingly according to actual usage requirements to achieve stable support and meet different support requirements. By increasing the opening angles of the legs 5, the center of gravity can be further lowered, the stability of the supporting tooling can be increased, and the flexibility during use can be improved.

[0044] The three groups of legs 5 are connected and the load is transferred through the central stabilizing component 6, thereby improving the stability, load-bearing capacity and anti-overturning ability of the supporting tooling and enhancing the lateral force resistance of the overall supporting tooling.

[0045] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
