Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to an insulation box transfer device and its usage method. Background Technology

[0002] The LNG carrier insulation box is a critical component in ensuring the ultra-low temperature (approximately -163°C) within the cargo hold. It minimizes heat transfer, prevents LNG vaporization, and safeguards the ship's structural integrity. The sides of the insulation box are lined with polyurethane foam, while the top is covered with plywood. Currently, the insulation box is typically handled using clamping fixtures or pneumatic suction cups. Both methods have significant drawbacks: 1. If clamping fixtures are used to clamp the insulation box, the clamping fixtures need to clamp the side of the insulation box for handling or moving. However, the side of the insulation box is made of polyurethane foam, which has very low strength and can easily damage the box structure. 2. If a pneumatic suction cup is used to hold the insulation box, the suction cup needs to be attached to the upper surface of the insulation box. However, the upper surface of the insulation box is made of plywood, which is relatively loose and has a large surface roughness. It is difficult to achieve good airtightness of the suction cup when it is attached. Sometimes, the suction cup fails to attach during the picking or transportation process, resulting in the insulation box falling and being damaged. Summary of the Invention

[0003] In view of this, the present invention provides an insulation box transfer device and its method of use, which uses the locking tongue groove structure of the insulation box itself as an anchor point. By locking the locking head of the insulation box transfer device into the locking tongue groove, the insulation box can be quickly transferred or transported with the help of the insulation box transfer device.

[0004] An insulation box transfer device includes a transfer box body. A vertical through hole is provided in the center of the transfer box body. A rotating shaft is installed in the through hole. The upper and lower ends of the rotating shaft extend out of the transfer box body. An adjustment handle is provided at the upper end of the rotating shaft and a locking head is provided at the lower end. Anti-rotation plates are provided at the bottom of the transfer box body. The anti-rotation plates are symmetrically arranged on both sides of the rotating shaft and the anti-rotation plates and the axis of the rotating shaft are located in the same plane. In the initial state, the center line of the clamp head and the center line of the rotating shaft are in the same plane. The clamp head and the anti-rotation plate extend into the clamp tongue groove of the insulation box, and the clamp head rotates 90° under the drive of the rotating shaft to lock the insulation box transfer device on the insulation box.

[0005] Preferably, the latch groove of the insulation box is an inverted T-shaped groove, the anti-rotation plate is locked in the vertical groove section of the latch groove, and the locking head is locked in the horizontal groove section of the latch groove.

[0006] Preferably, the clamp head is a rectangular rod-shaped structure, the width of the clamp head is smaller than the opening width of the clamp tongue groove, the length of the clamp head is smaller than the width of the horizontal groove section of the clamp tongue groove, and the thickness of the clamp head is smaller than the groove depth of the horizontal groove section of the clamp tongue groove.

[0007] Preferably, the width of the card head is 1mm-2mm smaller than the opening width of the card tongue groove, the length of the card head is 2mm-4mm smaller than the width of the horizontal groove section of the card tongue groove, and the thickness of the card head is 2mm-3mm smaller than the groove depth of the horizontal groove section of the card tongue groove.

[0008] Preferably, the thickness of the anti-rotation piece is 1mm-2mm smaller than the opening width of the tongue groove.

[0009] A method of using the aforementioned insulation box transfer device specifically includes the following steps: S1, insert the locking head and anti-rotation plate of the insulation box transfer device into the locking tongue groove of the insulation box; S2, Twist the adjusting handle, rotate the shaft to drive the clamp to rotate 90°, so as to lock the insulation box transfer device on the insulation box; S3, Hold the adjustment handle and lift and move the insulation box transfer device and insulation box to the target location; S4. After the insulation box is moved to the target position, turn the adjusting handle in the opposite direction to reset the clamp and remove the insulation box transfer device from the insulation box.

[0010] The beneficial effects of this invention are: 1. This invention utilizes the tongue groove structure of the insulation box itself as an anchor point. By locking the clamp head of the insulation box transfer device into the tongue groove, the insulation box can be quickly transferred or transported with the help of the insulation box transfer device without damaging the insulation box structure. Furthermore, there will be no connection failure between the insulation box transfer device and the insulation box during the transportation process, further ensuring the stability and reliability of the insulation box transportation.

[0011] 2. When using the insulation box transfer device of the present invention to transport insulation boxes, simply insert the clamp into the clamp tongue groove and rotate the adjusting handle to rotate the clamp 90° to lock the insulation box transfer device onto the insulation box. This allows for quick and effective connection between the two, improving not only the transport efficiency of the insulation box but also the stability and reliability of the transport. It is suitable for the installation of insulation boxes in the construction of LNG cargo tanks of LNG carriers, LNG fuel tanks of other ships, and LNG storage tanks on land.

[0025] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0026] This invention provides an insulation box transfer device, including a transfer box body 1-1. A vertical through hole is provided in the center of the transfer box body 1-1, and a rotating shaft 1-2 is arranged in the through hole. The upper and lower ends of the rotating shaft 1-2 extend out of the transfer box body 1-1. An adjustment handle 1-4 is provided at the upper end of the rotating shaft 1-2, and a locking head 1-3 is provided at the lower end. An anti-rotation plate 1-5 is provided at the bottom of the transfer box body 1-1. The anti-rotation plates 1-5 are symmetrically arranged on both sides of the rotating shaft 1-2, and the center line of the anti-rotation plates 1-5 and the rotating shaft 1-2 are located in the same plane. In the initial state, the center line of the clamp 1-3 and the center line of the rotating shaft 1-2 are in the same plane. The clamp 1-3 and the anti-rotation plate 1-5 extend into the clamping tongue groove 2 of the insulation box, and the clamp 1-3 rotates 90° under the drive of the rotating shaft 1-2 to lock the insulation box transfer device on the insulation box.

[0027] Specifically, the transfer box 1-1 is a cubic box with a through hole in the center. The rotating shaft 1-2 is inserted into the through hole, and the clamp 1-3 is fixed to the lower end of the rotating shaft 1-2.

[0028] The clamping head 1-3 is a rectangular rod-shaped structure. The width of the clamping head 1-3 is smaller than the opening width of the latch groove 2, the length of the clamping head 1-3 is smaller than the width of the horizontal groove section of the latch groove 2, and the thickness of the clamping head 1-3 is smaller than the groove depth of the horizontal groove section of the latch groove 2. In this embodiment, the width of the clamping head 1-3 is 1mm-2mm smaller than the opening width of the latch groove 2, the length of the clamping head 1-3 is 2mm-4mm smaller than the width of the horizontal groove section of the latch groove 2, and the thickness of the clamping head 1-3 is 2mm-3mm smaller than the groove depth of the horizontal groove section of the latch groove 2. This size ensures that the clamping head 1-3 can rotate freely within the latch groove 2.

[0029] The anti-rotation plate 1-5 is a rectangular piece, and its thickness is 1mm-2mm smaller than the opening width of the latch groove 2. This thickness design ensures that the anti-rotation plate 1-5 can be inserted into the latch groove 2 without wobbling. Two anti-rotation plates 1-5 are symmetrically arranged on both sides of the rotating shaft 1-2, and the center lines of the anti-rotation plates 1-5 and the rotating shaft 1-2 are in the same plane. In use, the anti-rotation plate 1-5 is inserted into the latch groove 2 along with the latch head 1-3. Specifically, the latch groove 2 of the insulation box is an inverted T-shaped groove. The anti-rotation plate 1-5 is engaged in the vertical groove section of the latch groove 2, and the latch head 1-3 is engaged in the horizontal groove section of the latch groove 2. By inserting the anti-rotation plate 1-5 into the vertical groove section of the latch groove 2, the transfer box 1-1 can be prevented from rotating along with the latch head 1-3 when the latch head 1-3 rotates.

[0030] like Figure 5 As shown, in use, the insulation box transfer device is inserted into the latch groove 2 from above the insulation box, that is, the anti-rotation plate 1-5 is locked in the vertical groove section of the latch groove 2, and the locking head 1-3 is locked in the horizontal groove section of the latch groove 2. Then, the adjusting handle 1-4 on the rotating shaft 1-2 is turned, and the rotating shaft 1-2 rotates the locking head 1-3 by 90° so that the locking head 1-3 interferes perpendicularly with the top plate of the latch groove on the insulation box, thereby locking the insulation box transfer device on the insulation box. Then, the insulation box transfer device and the insulation box are lifted upward by holding the adjusting handle 1-4, thereby achieving the purpose of quickly transporting or moving the insulation box.

[0031] like Figure 6 As shown, Figure 6 This is a schematic diagram for unlocking the insulation box transfer device. After moving the insulation box to its destination, turn the adjusting handle 1-4 in the opposite direction to reset the locking head 1-3 (i.e., rotate the locking head 1-3 until its center line is in the same plane as the center line of the rotating shaft 1-2), and then remove the insulation box transfer device from the locking tongue slot of the insulation box.

[0032] In a preferred embodiment, in order to prevent excessive stress concentration between the clamp head 1-3 and the top plate of the clamp tongue groove during the process of lifting the insulation box transfer device and the insulation box, which would cause deformation of the top plate of the clamp groove, multiple insulation box transfer devices can be inserted into the clamp tongue groove at equal intervals along the length direction of the clamp tongue groove 2 during use, and the transfer box bodies of multiple insulation box transfer devices can be connected into one unit by connecting rods or other components, so that all insulation box transfer devices and insulation boxes can be lifted as a whole.

[0033] The present invention also discloses a method for using an insulation box transfer device, specifically including the following steps: S1, insert the locking head 1-3 and anti-rotation plate 1-5 of the insulation box transfer device into the locking tongue groove 2 of the insulation box; S2, Twist the adjusting handle 1-4, rotate the shaft 1-2 to drive the clamp 1-3 to rotate 90°, so as to lock the insulation box transfer device on the insulation box; S3, hold the adjustment handles 1-4, lift and move the insulation box transfer device and insulation box to the target position; S4. After the insulation box is moved to the target position, turn the adjusting handle 1-4 in the opposite direction to reset the clamp 1-3 and remove the insulation box transfer device from the insulation box.

[0034] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
