Description

Technical Field

[0001] This utility model belongs to the field of nearshore box technology, and in particular relates to an integrated cast nearshore box lifting lug structure. Background Technology

[0002] Containers are modular tools capable of transporting packaged or unpackaged goods, facilitating loading and unloading by mechanical equipment. The greatest success of containers lies in their standardization and the resulting comprehensive transportation system. The ability to standardize a massive container weighing tens of tons, and to gradually build a global logistics system encompassing ships, ports, shipping routes, highways, transit stations, bridges, tunnels, and multimodal transport, is truly one of the greatest miracles of human history.

[0003] When handling containers, cranes are often used to lift them onto the lifting lugs. Offshore container lifting tools lift the lifting lugs on the inside of the four corner pieces of the container. However, most existing lifting lugs are made of multiple thick plates welded together. After welding, the welds need to be inspected for defects, which is not only time-consuming and labor-intensive, but also affects the strength of the lifting lugs. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an integrated cast offshore box lifting lug structure, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an integrally cast nearshore box lifting lug structure, comprising a base component and a lifting lug integrally formed on the upper end face of the base component, and further comprising:

[0007] A through hole is provided in the center of the lifting lug. An inclined slope is provided on the upper side of one side of the lifting lug, and the inclined slope is set in an arc shape.

[0008] The offshore container is located at the lower end of the base component. The offshore container has a locking mechanism inside for connecting the base component and the offshore container.

[0009] Furthermore, the left and right sides of the lifting lug are symmetrically fixed with reinforcing ribs, and the reinforcing ribs are fixed to the base component.

[0010] Furthermore, a connector is fixed to the lower end of the base component, and the cross-section of the connector is an "L" shaped structure, with a connecting groove on the outer side of the connector.

[0011] Furthermore, the locking mechanism includes a positioning slide groove, a connecting slide groove, a locking plate, and a locking rod. The positioning slide groove is located at one corner of the upper end face of the nearshore container, the connecting slide groove is located on one side of the positioning slide groove, the locking plate is slidably engaged with the inner side of the connecting slide groove, the locking rod is fixed in the center of the locking plate and extends outward from the nearshore container, and the cross-section of the locking plate is a "U" shaped structure, with the other end of the locking plate engaged with the connecting groove.

[0012] Furthermore, a baffle is fixed to the outer surface of the locking rod, and a return spring is provided at the upper end of the baffle, with the other end of the return spring in contact with the interior of the nearshore box.

[0013] This utility model has the following beneficial effects:

[0014] This utility model eliminates the need for welding between the base component and the lifting lug by setting the base component and the lifting lug as a cast integral structure. This reduces the number of welds and the amount of flaw detection work, and also improves the strength of the entire lifting lug assembly. The reinforcing ribs strengthen the lifting lug and prevent it from shifting or wobbling. Furthermore, the connector can slide and engage inside the positioning groove, pushing the connector to one side. Then, the reset spring and baffle can push the locking plate to engage with the connecting groove, thereby limiting the position of the connector and preventing it from shifting or wobbling. This allows for quick installation and control of the base component. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 As shown, this utility model is an integrally cast nearshore box lifting lug structure, including a base part 1 and a lifting lug 2 integrally formed on the upper end face of the base part 1, and further including:

[0024] The through hole 3 is located at the center of the lifting lug 2. An inclined slope 4 is provided on the upper side of one side of the lifting lug 2, and the inclined slope 4 is designed in an arc shape. The inclined slope 4 facilitates the connection of the hook, thereby facilitating subsequent transportation and handling.

[0025] The left and right sides of the lifting lug 2 are symmetrically fixed with reinforcing ribs 5, and the reinforcing ribs 5 are fixed to the base part 1. The reinforcing ribs 5 are triangular in structure, which can ensure the connection effect between the base part 1 and the lifting lug 2. Since the base part 1, the lifting lug 2 and the reinforcing ribs 5 are integrally formed, the strength of the lifting lug 2 can be guaranteed. The lower end of the base part 1 is fixed with a connector 6, and the cross-section of the connector 6 is "L" shaped. A connecting groove 601 is provided on the outer side of the connector 6. The connector 6 can be slidably embedded into the positioning groove 8. Since the connector 6 is "L" shaped, it can slide along the inside of the positioning groove 8. Since the connecting groove 601 is eccentrically set along the side of the connector 6, it is convenient to lock and limit the connector 6 in the future.

[0026] The offshore container 7 is located at the lower end of the base component 1. The offshore container 7 has an internal locking mechanism for connecting the base component 1 and the offshore container 7. The locking mechanism includes a positioning groove 8, a connecting groove 9, a locking plate 10, and a locking rod 11. The positioning groove 8 is located at one corner of the upper surface of the offshore container 7, and the connecting groove 9 is located on one side of the positioning groove 8. The locking plate 10 is slidably engaged with the inner side of the connecting groove 9. The locking rod 11 is fixed in the center of the locking plate 10 and extends outward from the offshore container 7. The locking plate 10 has a U-shaped cross-section, and the other end of the locking plate 10 is engaged with the connecting groove 601. When the connector 6 is slidably engaged inside the positioning groove 8, the locking rod 11 can be pulled outward. When the connector 6 is embedded inside the positioning groove 8, the connector 6 can be slid to one side. A baffle 12 is fixed on the outer surface of the locking rod 11, and a return spring 13 is provided at the upper end of the baffle 12. The other end of the return spring 13 is in contact with the interior of the sea box 7. Then, the locking rod 11 is released, and the return spring 13 can reset the baffle 12, which can push the locking plate 10 to slide and engage inside the connecting groove 601, thereby limiting the position of the connector 6 and preventing the connector 6 from shifting.

[0027] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
