Description

Technical Field

[0001] The invention relates to the technical field of ramp manufacturing, and in particular to an aluminum alloy ramp for a roll-on / roll-off ship and a welding auxiliary device thereof. Background Art

[0002] With the rapid development of the logistics industry and the increasing requirements for transportation efficiency and safety, the performance and quality of aluminum alloy ramps, as key connecting components between ro-ro ships and terminals, have received widespread attention. When loading and unloading vehicles and other cargo, ro-ro ships need a ramp that can adapt to different working conditions and has good stability and anti-skid performance to ensure the safe and rapid passage of vehicles and personnel. Traditional ramp designs often have problems such as bulky structure, inconvenient installation, and poor anti-skid effect, which makes it difficult to meet the needs of efficient operation of ro-ro ships.

[0003] Aluminum alloy has become an ideal material choice for manufacturing ramps due to its advantages such as light weight, high strength and strong corrosion resistance. However, aluminum alloy faces many challenges in the welding process. Due to the high thermal conductivity and large linear expansion coefficient of aluminum alloy, it is easy to produce large thermal deformation during welding, which will not only affect the dimensional accuracy and shape accuracy of the ramp, but also may cause the residual stress of the welded joint to increase, thereby reducing the overall structural strength and stability of the ramp. In addition, the welding process requirements of aluminum alloy are relatively strict. Improper selection of welding parameters can easily cause defects such as pores and cracks, further affecting the welding quality.

[0004] In order to overcome these problems and meet the performance requirements of aluminum alloy ramps for ro-ro ships, it is imperative to develop an efficient welding auxiliary device specifically for aluminum alloy ramps. Existing welding auxiliary equipment is often highly versatile, and is not adaptable enough to the welding of aluminum alloy ramps, which have a specific structure and material. It cannot effectively solve the deformation problem during the welding of aluminum alloys, and it is difficult to meet the complex structural shape and high-precision welding requirements of the ramp. Therefore, it is necessary to design a special welding auxiliary device that can accurately control the welding process, reduce deformation, and improve welding quality according to the actual working range, slope requirements, and welding characteristics of aluminum alloys of ro-ro ships.

[0030] The usage status of the present invention is: the present invention has many advantages, its structural design is exquisite and reasonable, the production cost is low, and the installation process is simple and easy. In the actual application of the aluminum alloy ramp, when the aluminum alloy ramp 1 for roll-on / roll-off ships needs to be activated, the operator can use the handle hole plate 1 7 and the handle hole plate 2 13 to pull, and at the same time rely on the flexible rotation of the moving wheel 1 6 and the moving wheel 2 14 to smoothly push the ramp plate 1 to the predetermined ideal position, ensuring that the connecting plate 9 at the right end can accurately and firmly achieve seamless docking with the corresponding part of the roll-on / roll-off ship. At this time, the anti-skid strips 2 carefully arranged on the top surface of the ramp plate 1 and the top surface of the connecting plate 9 will provide solid and reliable anti-skid protection for the driving of vehicles and the walking of people, and effectively prevent slipping. In the event of an accident, the transverse L-plate 3 and the longitudinal L-plate 4 are closely arranged and work together, which greatly strengthens the overall structural strength of the ramp plate 1 and the connecting plate 9, so that they have sufficient bearing capacity and can safely and stably withstand the weight and pressure applied by various vehicles and goods. The limit L-plate 12 and the protective layer 11 on its right side are like a solid shield, which can not only effectively limit the accidental displacement of the ramp during use, but also comprehensively protect the surrounding equipment and personnel from potential collision injuries. The inclined L-plate 16 and the anti-skid layer 15 on its bottom surface build a stable support system at the bottom of the left side of the ramp, further improving the anti-skid performance and stability of the ramp, ensuring that the entire ramp can maintain a reliable working state under various working conditions. For the use of the welding auxiliary device, first, carefully place the ramp plate 1 to be welded in the positioning groove 23 provided by the positioning groove seat 22 on the longitudinal moving mechanism 21, so as to achieve preliminary precise positioning, then properly place the iron pressing block 29 in the non-welding key area above the ramp plate 1, and then turn on the power of the electromagnetic chuck 28 to generate a strong magnetic force to tightly adsorb the iron pressing block 29, thereby firmly pressing the ramp plate 1 in the positioning groove 23, laying a solid foundation for the subsequent welding process, effectively ensuring the reliability of the welding process, and significantly reducing the risk of welding deformation. When the L plate (including the horizontal L plate 3, the longitudinal L plate 4 and the inclined L plate 16) is clamped, the L plate clamping device 2 513 and the oil cylinder 25139 in the L-plate clamping device 2514 will efficiently drive the movable clamping block 25134 to move smoothly toward the fixed clamping block 25133, so as to achieve a tight clamping of the L-plate. At the same time, the magnetic force generated by the electromagnet 251311 after being energized can accurately attract the iron block 251310 on the movable limit block 25136, and flexibly enhance the clamping force according to the actual welding requirements, so as to ensure that the L-plate always maintains a stable position during the entire welding process. When the L-plate is firmly clamped, the moving device 26 is started, and the motor 4 261 drives the screw 3 264 to rotate at a uniform speed, so as to enable the transverse seat 265 to smoothly move laterally in the slide groove 263 of the crossbeam 262, and quickly adjust to an appropriate transverse position.Subsequently, the motor 5 267 drives the screw 4 268 to rotate, driving the lifting seat 269 to move up and down smoothly in the guide hole seat 266, thereby accurately guiding the adjustable clamping mechanism 25 to descend to a suitable height, and the longitudinal moving mechanism 21 can flexibly move the ramp plate 1 to a suitable longitudinal position to meet the needs of different welding parts. In addition, the motor 1 254 in the adjustable clamping mechanism 25 drives the driving gear 253 to rotate, thereby driving the driven gear 255 and the rotating seat 256 to rotate, so that the guide groove seat 251 can be flexibly rotated. Turn to the appropriate angle to perfectly adapt to the welding operation requirements of the L plate in different directions. The motor 2511 and the motor 3 2516 can respectively drive the screw 2510 and the screw 1 259 to rotate, so that the movable seat 1 2512 and the movable seat 2 2515 move relative to or oppositely in the guide groove 258, accurately meeting the clamping requirements of L plates of different lengths at different positions, effectively ensuring the movement stability of L plates of different lengths after clamping, greatly improving the welding quality, and providing all-round guarantee for the efficient and high-quality welding of aluminum alloy ramps. ;
