Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to an auxiliary installation device for marine support pipes. Background Art

[0002] In the stage of shipbuilding subassembly or sub-section erection, especially in areas with larger hull lines, a combined mechanism of support pipes and stabilizing frames is often used to support the hull construction.

[0003] Currently, the commonly used support pipe has an outer diameter of 325 mm, while the caliber of the commonly used stabilizing frame top plate is only 330 mm. It is very difficult to lift a support pipe with a length of more than ten meters into a stabilizing frame with a height of 8 meters only by a crane. Usually, construction workers need to work at heights and manually control the end of the support pipe to be placed into the stabilizing frame to achieve this. Since the lifting point of the support pipe is at the top, for a long strip-shaped structure of more than ten meters, the end will swing due to factors such as wind speed and the sway of the lifting rope, which is extremely dangerous for construction workers working at heights, and the entire operation process consumes a large amount of construction time. Summary of the Invention

[0004] In view of this, the utility model provides an auxiliary installation device for marine support pipes to solve the problems existing in the above background art.

[0005] An auxiliary installation device for marine support pipes includes a fixed groove body and a sliding adjustment component;

[0006] A plurality of the fixed groove bodies are provided, and the plurality of fixed groove bodies are evenly distributed on the outer circumferential surface of the support pipe. A sliding adjustment component is movably arranged in the sliding groove of each fixed groove body, and two adjacent sliding adjustment components are fixed to each other;

[0007] The sliding adjustment component includes a T-shaped slider and an arc-shaped disc fixed to the top of the web of the T-shaped slider. The web of the T-shaped slider is an inverted triangle, and the panel of the T-shaped slider is stuck in the sliding groove of the fixed groove body and can slide along the sliding groove to force the center line of the support pipe to coincide with the center line of the inner hole of the stabilizing frame top plate through the interference between the hypotenuse of its web and the inner hole of the stabilizing frame top plate during the descent of the support pipe.

[0008] Preferably, the sliding groove of the fixed groove body is a T-shaped sliding groove.

[0009] Preferably, the fixed groove body includes two symmetrically arranged L-shaped bodies and cover plates fixed to the top and bottom of the two L-shaped bodies. The two L-shaped bodies are spaced apart to form a T-shaped sliding groove therebetween.

[0010] Preferably, the acute angle of the web of the T-shaped slider is 16°.

[0011] Preferably, the angle of the arc-shaped disc is 120°, the ends of two adjacent arc-shaped discs are butted and welded together, and an arc-shaped notch is formed in the inner side of each arc-shaped disc.

[0012] Preferably, the arc-shaped notch is a semi-circular notch.

[0013] Preferably, the outer diameter of the support pipe is smaller than the aperture of the inner hole of the stabilizer frame top plate.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The structure of the utility model is simple and practical. Fixing this device at the end of the support pipe can automatically adjust the position of the support pipe during the process of hoisting the support pipe onto the stabilizer frame. There is no need for workers to work at heights, and the long strip structure will not cause harm to construction workers when swaying at high altitudes, reducing the construction safety risk of workers.

[0016] 2. The utility model is made of conventional shipbuilding materials, with low cost. This device can be installed on the support pipe in a horizontal and low-altitude state, and the installation steps are simple and convenient, greatly reducing the construction cost of the enterprise.

[0017] 3. When disassembly and recycling are required, the support pipe can be taken out according to conventional operations. Since the groove body structure of this application is small, it basically has no impact on the stacking of the support pipe, and only taking out the sliding adjustment component can meet the requirements of stacking and recycling.

[0031] To better understand the technical solution of the present utility model, the present utility model will be described in detail below with reference to the drawings.

[0032] The present utility model provides a marine support pipe auxiliary installation device, which includes a fixed groove body 1 and a sliding adjustment component 2.

[0033] A plurality of the fixed groove bodies 1 are provided, and the plurality of fixed groove bodies 1 are evenly distributed on the outer circumferential surface of the support pipe 3. A sliding adjustment component 2 is movably provided in the sliding groove of each fixed groove body 1, and two adjacent sliding adjustment components 2 are fixed to each other.

[0034] Specifically, the fixed groove body 1 includes two symmetrically arranged L-shaped bodies 1.1 and cover plates 1.2 fixed to the tops and bottoms of the two L-shaped bodies 1.1. The two L-shaped bodies 1.1 are spaced apart to form a T-shaped sliding groove therebetween. In this embodiment, the length of the L-shaped body 1.1 is 360 mm, that is, the formed T-shaped sliding groove is also 360 mm.

[0035] The sliding adjustment assembly 2 includes a T-shaped slider 2.1 and an arc-shaped disc 2.2 fixed to the top of the web of the T-shaped slider 2.1. The web of the T-shaped slider 2.1 is an inverted triangle. The panel of the T-shaped slider 2.1 is stuck in the chute of the fixed chute body 1 and can slide along the chute. During the descent of the support tube 3, the interference between the hypotenuse of its web and the inner hole 5 of the stabilizer frame top plate forces the center line of the support tube 3 to be adjusted to coincide with the center line of the inner hole 5 of the stabilizer frame top plate.

[0036] In this embodiment, the T-shaped slider 2.1 is stuck in the T-shaped chute of the fixed chute body 1. The width of the panel of the T-shaped slider 2.1 is slightly smaller than the width of the corresponding part of the chute in the T-shaped chute. Preferably, the width of the panel of the T-shaped slider 2.1 is 0.3 - 0.5 mm smaller than the width of the corresponding part of the chute in the T-shaped chute. The web of the T-shaped slider 2.1 is an inverted triangular plate with an acute angle of 16° and the length of the right-angled side is 300 mm.

[0037] The angle of the arc-shaped disc 2.2 is 120°. The ends of two adjacent arc-shaped discs 2.2 are butt-jointed and welded together. In this embodiment, three sets of sliding adjustment assemblies are provided. In this way, the arc-shaped discs 2.2 of the three sets of sliding adjustment assemblies can be spliced into a disc, and the three arc-shaped discs 2.2 also slide synchronously along the chute.

[0038] An arc-shaped notch 2.3 is provided on the inner side of each arc-shaped disc 2.2. In this embodiment, the arc-shaped notch 2.3 is a semi-circular notch.

[0039] Taking the support tube with a common outer diameter of 325 mm and an 8 m high stabilizer frame as an example, the use process of the above device will be described in detail below.

[0040] When using the above device to assist in installing the support tube 3, the following steps are included:

[0041] S1, place the support tube 3 in a horizontally overhead state, and then install the device of the present application on the support tube 3.

[0042] When installing the device of the present application, first symmetrically fix two L-shaped bodies 1.1 at a certain position 810 mm away from the end of the support tube 3, and then install the sliding adjustment assembly 2 in the fixed chute body 1. When installing the T-shaped slider 2.1 of the sliding adjustment assembly 2, attention should be paid to the installation direction of the T-shaped slider 2.1 to ensure that the web of the T-shaped slider 2.1 is in an inverted triangular state when the support tube 3 is hoisted; then weld and fix the cover plate 1.2 at both ends of the two L-shaped bodies 1.1.

[0043] Then, install the remaining two sets of fixed chute bodies 1 and sliding adjustment assemblies 2 in place at other positions 810 mm away from the end of the support tube 3 in the same way.

[0044] After the three fixed chutes 1 and the sliding adjustment components 2 are all installed in place, weld and fix the joints of the three arc-shaped discs 2.2.

[0045] S2. Enlarge the diameter of the inner hole 5 of the stabilizer frame top plate of the stabilizer frame 4 to 460 mm.

[0046] S3. Fix the crane hook to the top end of the support pipe 3, start the crane, lift the support pipe 3, and insert the support pipe 3 into the inner hole 5 of the stabilizer frame top plate from above.

[0047] Since the diameter of the support pipe 3 is 325 mm, which is much smaller than the diameter of the inner hole 5 of the stabilizer frame top plate (460 mm), it is very easy for the support pipe 3 to extend into the inner hole 5 of the stabilizer frame top plate.

[0048] S4. Since the diameter of the support pipe 3 is much smaller than the diameter of the inner hole 5 of the stabilizer frame top plate, the support pipe 3 will be eccentric during the descending process.

[0049] When the support pipe 3 is eccentric (tilted) during the descending process and at least one web of the T-shaped slider 2.1 has contacted the edge of the inner hole 5 of the stabilizer frame top plate, under the block of the inner hole 5 of the stabilizer frame top plate, the T-shaped slider 2.1 in contact with the edge of the inner hole 5 of the stabilizer frame top plate will move upward along the chute until it contacts the cover plate of the fixed chute 1 (the T-shaped slider 2.1 in contact with the edge of the inner hole 5 of the stabilizer frame top plate will also drive the corresponding arc-shaped disc 2.2 to move upward synchronously). During this process, since the three arc-shaped discs 2.2 are welded and fixed together, the T-shaped slider 2.1 not in contact with the edge of the inner hole 5 of the stabilizer frame top plate will also slide upward until it contacts the cover plate of the fixed chute 1. At this time, the webs of the three T-shaped sliders 2.1 just get stuck on the inner hole 5 of the stabilizer frame top plate;

[0050] After that, under the gravity of the support pipe 3 (at this time, the center of gravity of the support pipe 3 is below the device of the present application), the lower part of the support pipe 3 will tilt towards the side of the "T-shaped slider 2.1 in contact with the edge of the inner hole 5 of the stabilizer frame top plate", that is, the lower part of the support pipe 3 will be pressed down, so that the T-shaped slider 2.1 not in contact with the edge of the inner hole 5 of the stabilizer frame top plate contacts the inner hole 5 of the stabilizer frame top plate to adjust the position of the support pipe 3 and ensure that the center line of the support pipe 3 coincides with the center line of the inner hole 5 of the stabilizer frame top plate.

[0051] When the position of the support pipe 3 is adjusted, the three T-shaped sliders 2.1 just get stuck on the inner hole 5 of the stabilizer frame top plate. At this time, the support pipe 3 and the stabilizer frame 4 are in a clamped state, and the support pipe 3 is installed in place.

[0052] It should be clear that the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.
