Background technique

The hull needs to be transported during the assembly phase or the assembly phase. The straighter section or the main section can directly pad the plank on the gantry to support the support and cushion. However, for a segment or a total segment with a relatively large curvature of the whole or local position, if the support position is simply supported by a skid, and there is no rigid joint segment or the total segment cannot be well fixed, the transportation stability will be affected. Sex and safety, so the current support for the location with large curvature is welded between the gantry and the segment or the total section with round or double channel steel to play the connection and support to ensure the safety of transportation. Although the stability of the segment or the total section is supported by round or double channel steel, the stability is relatively good, but the structural curvature of each segment or total segment is different because the assembly method of each segment or total segment is different. Different from each other, the position that needs to be supported, the height of the reinforcing material, and the like are naturally different, which is not conducive to the classification management and recycling of the transportation door frame. The existing recycling needs to cut and remove the reinforcing material for support, and then re-weld, which will leave many uneven cut marks on the door frame, which not only affects the appearance, but also wastes the reinforcing material, and at the same time, the cutting block is placed on the concave and convex cut marks. On the top, the stud support is uneven, the force is uneven, the stability is poor, and there is a safety hazard.

Summary of the invention

The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

As shown in FIGS. 1 to 3, in the present embodiment, a hull transport tooling according to the present invention includes a gantry 1 for transporting a hull and detachably disposed on the gantry 1 for performing a hull Supporting a plurality of support base tools 2, the support base tool 2 includes a support base and a support top plate 201, and the support base is provided with a receiving groove adapted to the beam 101 of the door frame 1, the support base The gantry 1 is disposed on the gantry 1 , and the beam 101 is located in the accommodating groove, and the supporting top plate 201 is fixedly connected to the supporting base.

By providing a detachable support tooling 2 on the gantry 1, a reinforcing material is welded between the supporting top plate 201 of the supporting tooling 2 and the segment or the total section of the hull to strengthen the hull, thereby realizing the segmentation of the hull. Or the total segment is fixed. After the segment or the total section of the hull is fixed to the transport tooling, the crane can be used to transport the segment or the total segment. When it is necessary to lift the segmentation of the hull or the fixing of the total slab, it is only necessary to cut the end of the reinforcing material connected to the segment or the main section at a position close to the outer plate to release the fixing of the segment or the total segment, and further use The forklift or crane will remove the support tool 2 with reinforcement from the gantry 1 for the next use.

In the next use, the height of the support tool 2 can be measured according to the distance between the outer panel of the hull and the gantry 1, or the appropriate height with the reinforcement removed before (the height at this time is the support tool) 2 and the total height of the reinforcing material) Supporting tooling 2, to achieve multiple use of reinforcing materials, can reduce welding times and reduce waste of resources.
