Description

Technical Field

[0001] The present invention relates to the field of shipbuilding, in particular to a tower support jacking and shifting mechanism and a jacking and shifting method for shipbuilding. Background Art

[0002] With the development trend of larger ships, the outer plate supports in the loading stage are getting higher and higher, especially the bow line is larger. After the whole ship structure is connected, the support tooling is located directly under the hull structure. It is very difficult to lift the support tooling before the ship is undocking. Due to the high height, heavy weight and high center of gravity of the support, the on-site can only rely on forklifts to hit the support tooling, causing a slight displacement of the support. Then, through continuous impact, the support is shifted to a position where the crane can hook it. This method has the following shortcomings:

[0003] First, if a crane is used to move and fine-tune the supporting tooling, it will occupy valuable crane resources and be detrimental to the control of construction costs.

[0004] Second, the forklift's constant hard impact on the supporting tooling causes the support to shake. In addition, the ground may be uneven, and the support may fall over, posing a major safety hazard.

[0005] Third, the hard impact of the forklift on the supporting tooling will cause certain damage to the supporting tooling itself. If this operation is carried out for a long time, it will definitely affect the strength of the supporting tooling itself;

[0006] Fourth, the support is displaced and adjusted by forklift impact, and only a small displacement can be performed each time, resulting in low construction efficiency and low production efficiency.

[0007] In the prior art, Chinese utility model patent 201820114623.5 discloses a combined support frame for ships. This application adopts a combination method to meet the use requirements of different support heights, forming a ship tower support device with different support heights.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and specific examples, but the scope of protection of the present invention shall not be limited thereto.

[0045] like Figure 1 As shown, the present invention first designs and manufactures a tower support jacking and shifting mechanism for ship construction, which is composed of four main parts: a corbel support frame 1, a fixing hoop 2, a walking mechanism 3, and a jacking oil pump 4.

[0046] Among them, the tower support jacking and shifting mechanism includes a tower support base and a tower support column 15 and a tower support base leg 16 that are perpendicular to each other on the tower support base. A corbel support frame 1 is welded and fixed on the tower support column 15, and a fixing hoop 2 is fixed and welded on the tower support base leg 16. A walking mechanism 3 is provided inside the fixing hoop 2, and a jacking oil pump 4 is provided directly above the walking mechanism 3. The jacking oil pump 4 pushes the corbel support frame 1 to drive the tower support jacking and shifting mechanism to lift up. The supporting gravity of the tower support jacking and shifting mechanism moves the walking mechanism 3 downward, and the tower support jacking and shifting is completed by using a forklift to push.

[0047] like Figure 2-3As shown, the corbel support frame 1 serves as a lifting point for the tower support lifting and shifting mechanism and includes a base plate 11, transverse reinforcement ribs 12, vertical reinforcement ribs 13 and base plate anti-top reinforcement ribs 14. The transverse reinforcement ribs 12 are transversely connected to the tower support column 15, and the vertical reinforcement ribs 13 are longitudinally connected to the tower support base legs 16. The base plate 11 is a right-angled isosceles triangle structure. The base plate 11 is fixedly welded on the supporting column 15. The two right-angled sides of the base plate 11 are respectively welded to the transverse reinforcement ribs 12 and the longitudinal reinforcement ribs 13 to form a triangular prism structure. A base plate anti-top reinforcement rib 14 is provided above the base plate 11 and is welded to the base plate 11, and at the same time connects the transverse reinforcement ribs 12 and the vertical reinforcement ribs 13.

[0048] like Figure 4 As shown, the fixing hoop 2 is used to secure the traveling mechanism 3. The first and second transverse panels 22, 24, and first and second longitudinal panels 21, 23 form a rectangular structure. The fixing hoop has no top or bottom and is welded to the tower support base leg 16. The length and width of the rectangular structure are equal. The first and second transverse panels 21, 24 are both rectangular components, welded to the longitudinal and transverse tower support base legs 16, respectively. The panels' lower edges align with the base's lower panel, and the panels' upper edges are 33mm-37mm higher than the base panel, facilitating welding. The second longitudinal panel 23 and first transverse panel 22 are parallel to the first and second transverse panels 21, 24, respectively. The panels extend lengthwise into the interior of the I-beams of the tower support base leg 16, where they are embedded and welded in place. The width of the second longitudinal panel 23's main structure is 95mm-105mm smaller than the width of the other panels, facilitating the smooth insertion of the traveling mechanism 3 into the fixing hoop 2.

[0049] like Figure 5-6As shown, the walking mechanism 3 is used to constrain the horizontal displacement movement in the fixed hoop, including a top plate 31, an end plate 32, a side plate 33, a lifting ring 34, a walking wheel 35, a shaft sleeve 36, an axle pin 37, and a gasket 38 to form a semi-enclosed mechanical device that can be freely carried and maintained. The top plate 31, two end plates 32 and two side plates 33 form a rectangular parallelepiped structure of the walking mechanism without a bottom. The length and width of the rectangular parallelepiped are equal, which is larger than the length and width of the fixed hoop 2. The size is 3mm-7mm smaller. The upper surface of the top plate 31 in the height direction is basically the same as the tower support base leg 16, ensuring that the walking mechanism can be smoothly placed in the fixing hoop without causing eccentricity during the walking process due to excessive gaps. The side plate 33 has a hole for welding and fixing the axle pin 37. The axle pin 37 is fixedly connected to the walking wheel 35. The axle sleeve 36 is provided between the axle pin 37 and the walking wheel 35. A gasket 38 is provided between the walking wheel 35 and the side plate 33. The side plate 33 and the top plate 31 and the side plate 33 and the axle pin 37 are all welded together. The installation height of the walking wheel 35 exceeds the lower end surface of the rectangular structure of the walking mechanism 3 by 30mm, ensuring that the maximum lifting height of the tower support is 30mm. There are two lifting rings 34, located on both sides above the top plate, to facilitate the transportation of the entire walking mechanism.

[0050] The jacking oil pump 4 is a pre-assembled hydraulic mechanical device that can be purchased directly. Its rated load must meet the required tonnage for the lift. The height of the jacking oil pump plus half the lift stroke height is approximately equal to the height between the support frame base and the upper surface of the traveling mechanism. By placing the jacking oil pump on the constrained traveling mechanism, the tower support jacking and shifting mechanism is lifted. Rolling friction replaces static friction, enabling autonomous shifting of the tower support jacking and shifting mechanism with the assistance of the forklift's jacking force.

[0051] Based on the design of the above-mentioned special mechanism, the present invention also provides a method for realizing displacement and lifting by using the above-mentioned tower support jacking and shifting mechanism. The method includes the following steps:

[0052] S1. Weld the bracket support frame 1 structure onto the tower support column 15, estimate the specifications of the jacking oil pump 4, actually lay out the relevant parts of the bracket support frame 1, and weld and fix each part onto the tower support column 15;

[0053] S2. Perform actual layout of the relevant parts in the fixing hoop 2 and weld the fixing hoop 2 structure on the tower support base legs 16;

[0054] S3, placing the four sets of the walking mechanisms 3 into the four fixing hoops 2, with the directions of the walking wheels 35 being consistent and aligned with the direction of the predetermined route to be shifted;

[0055] S4, placing the four sets of jacking oil pumps 4 directly above the four traveling mechanisms 3;

[0056] S5, starting the jacking oil pump 4, applying a jacking thrust, and the tower support jacking and shifting mechanism is lifted smoothly until the tower support jacking and shifting mechanism body is off the ground;

[0057] S6. Open the mechanical lock of the jacking oil pump 4 and loosen the hydraulic device;

[0058] S7, using the forklift arm of the forklift to push against the tower support column 15, pushing the tower support lifting and shifting mechanism to shift;

[0059] S8. After reaching the target position, start the jacking oil pump 4, loosen the mechanical lock, and slowly lower the tower support jacking and shifting mechanism until the base falls steadily to the ground, completing the moving process;

[0060] S9. Take out the walking mechanism 3 and place it in a special tool storage area for next use. The tower support jacking and shifting of the ship construction is completed.

[0061] This lifting and shifting method does not require a crane to fine-tune the position of large tower supports, effectively freeing up crane resources; it avoids the safety hazards caused by rough construction using forklifts, and quickly and smoothly moves the support tooling to the target position, improving production efficiency, reducing safety risks, and lowering production costs.

[0062] The above is only one implementation of the present invention. Based on the same idea, other similar methods and structures can be replaced, not limited to the steps and structural components described. In short, the scope of protection of the present invention also includes other obvious changes and substitutions for those skilled in the art.
