Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shipbuilding, and particularly relates to a hatch cover rubber strip pressing plate correcting device. BACKGROUND

[0002] A hatch coaming structure is arranged on the periphery of an opening above a cargo hold of a container ship, a heavy-lift ship or the like, and the top end of the hatch coaming structure is a hatch coaming top plate (a carbon steel plate, with a relatively large thickness, generally not less than 25 mm). A circumferential hatch cover rubber strip pressing plate (an austenitic stainless steel plate, with a relatively small thickness, generally 8-15 mm) is arranged on and welded to the hatch coaming top plate. The hatch cover rubber strip pressing plate corresponds to the position of a hatch cover rubber strip (arranged below the hatch cover structure) in one-to-one correspondence. The hatch cover falls above the hatch coaming top plate, the hatch cover rubber strip is in full contact with and pressed against the hatch cover rubber strip pressing plate (to achieve water tightness), and the hatch cover rubber strip pressing plate is prevented from rusting and contaminating the hatch cover rubber strip.

[0003] The installation requirements for the hatch coaming top plate and the hatch cover rubber strip pressing plate are that the two should be in close contact and no gap is allowed. However, the hatch cover rubber strip pressing plate is generally processed by shearing due to its relatively small thickness, and a certain amount of torsional deformation is easily generated in the shearing process. A certain amount of bending deformation is also easily generated in the shearing, stacking, transportation and hoisting processes, which results in that, after the hatch cover rubber strip pressing plate is hoisted into position, a gap exists between the hatch cover rubber strip pressing plate and the hatch coaming top plate due to the local bending or torsional deformation of the hatch cover rubber strip pressing plate, and the installation technical requirements are not met.

[0004] The prior art is to first weld a 7-shaped code on the hatch coaming top plate, then insert an iron wedge and knock the iron wedge, the iron wedge exerts pressure on the hatch cover rubber strip pressing plate, and temporary correction, pressing and fixing are realized between the hatch cover rubber strip pressing plate and the hatch coaming top plate. Then, positioning welding is performed between the hatch cover rubber strip pressing plate and the hatch coaming top plate in the corrected area. After the positioning welding is completed, the iron wedge and the welded 7-shaped code are removed, the correction and positioning welding of the hatch cover rubber strip pressing plate at one place are completed, and the above method is prepared for the correction and positioning welding of the next place of the hatch cover rubber strip pressing plate. In the above way, the 7-shaped code needs to be welded and removed each time for correction, which results in a large amount of work and low efficiency. Moreover, the 7-shaped code leaves a welding root on the hatch coaming top plate after being removed, and the welding root needs to be cleaned and the cleaned welding root needs to be repaired and polished, which is low in efficiency and high in cost.

[0005] Therefore, a hatch cover rubber strip pressing plate correcting device is needed to solve the above problems. SUMMARY
