Description

Technical Field

[0001] The present invention belongs to the technical field of shipbuilding, and particularly relates to an auxiliary floor positioning device and a positioning method thereof. Background Art

[0002] During the process of ship block construction, especially when fabricating the blocks of the parallel middle bottom part of the ship, a large number of floors need to be installed. These floors are all hoisted piece by piece by a crane and then fixed by welding supports or tack welding. Only after that can the crane be released to continue installing the next partition. After all partitions are installed, all supports need to be removed. Since the supports are fixed by welding, the welding points need to be repaired and polished during removal, which not only wastes a large amount of labor but also affects the product quality. This method has both low installation efficiency and high subsequent additional costs, and occupies a large amount of crane resources, which is not conducive to the production progress of the overall project. Summary of the Invention

[0003] In order to solve the problems of low installation efficiency and high subsequent additional costs in the prior art, the present invention provides an auxiliary floor positioning device and a positioning method thereof.

[0004] Among them, the main structure of the auxiliary floor positioning device is two symmetric angle steels facing away from each other. The two angle steels are fixedly connected by a connecting plate. The gap between the two angle steels is used to place longitudinal partitions; slots are formed in the angle steels, and the slots are used to insert transverse partitions; clamping members are arranged at positions on the angle steels avoiding the slots for locking the tooling after the partitions are inserted.

[0005] Further, the gap is formed between the vertical sides of the two angle steels, and the gap matches the thickness of the longitudinal partition.

[0006] Further, the slots are arranged perpendicular to the gap, and the slots pass through the vertical sides and horizontal sides of the angle steels; the length of the slots located in the vertical side part of the angle steels is less than the height of the vertical side of the angle steels, and the length of the slots located in the horizontal side part of the angle steels is equal to the length of the horizontal side of the angle steels.

[0007] Further, the clamping member includes a nut, and the nut is fixed on one side of the horizontal side of the angle steel located at the slot.

[0008] Further, a locking bolt is inserted into the nut, and the locking bolt is perpendicular to the part of the horizontal side of the angle steel where the slot is located.

[0009] Further, a fastening handle is provided at the end of the locking bolt.

[0010] The positioning method of the above-mentioned auxiliary floor positioning device includes the following steps:

[0011] Install and fix the longitudinal partition structure first, and ensure the safety and stability of the longitudinal partition.

[0012] Install the tooling at the intersection position of the transverse ribs to be installed, and pay attention to the position of the card slot of the angle steel facing the longitudinal partition board.

[0013] Fix the tooling on the longitudinal partition by tightening the fastening bolts.

[0014] Use a crane to insert the rib from the card slot between the two angle steels of the tooling. After the lower end of the rib is in place, the crane can be released.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The present invention is simple to manufacture, weighs only about 3KG, is convenient to install and disassemble during use, can be operated by a single person, and has high practicability. When using this tooling to position the ribs, the positioning time of each rib can be shortened by about 20 minutes. At the same time, the saved crane can be used for hoisting other materials, which has a good effect on improving the efficiency of the entire project. In addition, when using this tooling to position the ribs, welding supports for fixation are not required, thus reducing the labor costs such as welding and grinding for the installation and removal of the supports.

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0023] The present application proposes an auxiliary rib positioning device. According to the characteristics that the partitions at the parallel middle bottom part of the ship are crisscrossed, and the longitudinal partitions are continuous while the transverse partitions are discontinuous, a tooling is designed and fixed at the intersection of the longitudinal and transverse partitions by bolts and combined angle steels. An opening slot is provided on one side of the angle steel, and when the transverse rib is hoisted, it is inserted through this slot and the crane can be released after it is placed stably.
