Description

Technical Field

[0001] The utility model relates to the technical field of hull component processing, in particular to an anti-falling square steel cutting platform. Background Art

[0002] The ship is equipped with a large number of ballast tanks to facilitate load adjustment. The ballast tanks run through the platform or other hull structures. In order to meet the needs of rapid pumping, drainage or reducing the weight of the structure, a large number of lightening holes are usually opened on the horizontal platform plate. At the same time, in order to meet the needs of subsequent crew inspections and ballast tank maintenance, such as Figure 1 and Figure 2 As shown, anti-falling square steel 6 is arranged on the lightening hole 5 to meet the needs of personnel passage and the walking safety of crew members.

[0003] Anti-fall square steel is typically 22mm x 22mm square. During installation, to prevent the formation of a slippery corrosion film on the steel after exposure to seawater, which could increase the risk of slipping for crew members, the steel is installed at a 45-degree angle in the lightening holes, creating a diamond-shaped structure to increase friction. To avoid sharp corners at either end, the steel is typically beveled at a 45-degree angle after leaving a 15mm gap. To reduce procurement costs, manufacturers typically purchase meter-long steel bars and then cut them in-house without dedicated cutting machines, resulting in slow cutting and low efficiency.

[0025] According to the anti-falling square steel cutting platform of the present invention, when working, the distance between the first longitudinal girder 1 and the second longitudinal girder 2 is first adjusted by the distance adjusting mechanism 3; then, one end of the anti-falling square steel 6 is laid in the first mounting groove 11 on one side and protrudes from the first longitudinal girder 1, and the other end of the anti-falling square steel 6 is laid in the second mounting groove 12 on the other side and protrudes from the second longitudinal girder 2; then the platform 4 is laid on the anti-falling square steel 6, and a cutting device is arranged on the platform 4, and according to actual needs, the upper end of the part of the anti-falling square steel 6 protruding from the first longitudinal girder 1 and the upper end of the part protruding from the second longitudinal girder 2 are cut at a 45-degree angle respectively. Compared with the single manual cutting method in the prior art, it can be directly arranged according to on-site expectations, the cost is lower, the construction arrangement is simpler, and the work efficiency is improved; at the same time, since there are multiple first mounting grooves 11 and second mounting grooves 12, the anti-falling square steel 6 can be cut in batches, reducing labor consumption, and the operation is more convenient, which can reduce labor intensity.

[0026] Exemplarily, the distance adjustment mechanism 3 includes a first linear guide pair 33, a second linear guide pair 34, a first slide 31, and a second slide 32. The first linear guide pair 33 and the second linear guide pair 34 are arranged in parallel. The first longitudinal girder 1 slides on the first linear guide pair 33 and the second linear guide pair 34 via the first slide 31; the second longitudinal girder 2 slides on the first linear guide pair 33 and the second linear guide pair 34 via the second slide 32.

Therefore, when the drive motor 36 is working, the screw nut pair 35 can convert the rotation of the drive motor 36 into linear motion, thereby driving the first slide 31 to drive the first longitudinal girder 1 to move forward and backward along the first linear guide pair 33 and the second linear guide pair 34, and at the same time can drive the second slide 32 to drive the second longitudinal girder 2 to move forward and backward along the first linear guide pair 33 and the second linear guide pair 34, thereby realizing the toward or away movement of the first longitudinal girder 1 and the second longitudinal girder 2, which is suitable for batch cutting of anti-fall square steels 6 of different lengths and specifications, and the adjustment method is quick.

[0028] Exemplarily, the cutting device is preferably a cutting carriage with a flame cutting head, which is more flexible and more efficient.
