Automatic walking operation vehicle for ship hatch coaming

Abstract

The invention relates to the technical field of machining of a ship hatch coaming, and discloses an automatic walking operation vehicle for a ship hatch coaming. The automatic walking operation vehicle for the ship hatch coaming comprises a first vehicle frame and a second vehicle frame, and the first vehicle frame is telescopically connected to the upper part of the second vehicle frame in an overlapping mode, a walking wheel device for moving on a hatch coaming panel and at least one limiting wheel device for moving on the outside surface of a stiffener plate are arranged on the first vehicle frame, a plurality of support wheel devices for sliding on the inner side surface of a web plate are arranged on the second vehicle frame; and wheel axes of the limiting wheel devices and wheel axesof the supporting wheel device are separately perpendicular to the wheel axis of the walking wheel device, and the moving directions of the walking wheel device, the limiting wheel devices and the supporting wheel devices are the same. The automatic walking operation vehicle for the ship hatch coaming can provide a working platform for the work of the automatic welding, grinding, cutting, carbonarc gouging, flaw detection and the like at the stage of sectional carrying of the ship hatch coaming, the welding efficiency and quality are improved, the working environment is improved, the construction cost is reduced, and the safety in the working process is improved.

Description

technical field [0001] The invention relates to the technical field of ship hatch coaming processing, in particular to a ship hatch coaming automatic walking operation vehicle. Background technique [0002] The webs of the hatch coaming sections of container ships are all thick plates because they participate in the calculation of the longitudinal strength, and the T-shaped joints between the webs and the main deck are generally required to be deep penetration welding or full penetration welding, so the butt welding of the webs and the T Shaped joints have a large amount of welding and high quality requirements. See attached figure 1 , the outer side of the hatch coaming panel 1 (the side near the outer plate) is generally provided with stiffeners 4, which is not conducive to the implementation of automatic welding, but the inner side of the web 2 (the side near the midship) usually has no other structural design and is relatively smooth. Conducive to the implementation of...

Problems solved by technology

However, since the hatch coaming is located on the main deck 3 of the hull structure, and its position is relatively high, there are certain obstacles in the implementation of automatic welding due to the limitations of traditional scaffolding columns and storey heights. Larger semi-automatic carbon dioxide welding

[0003] At present, the industry adopts the method of erecting stent-type scaffolding from the bottom of the cabin to the position around the hatch. The height varies from a few meters to tens of meters depending on the height of the cabin of the ship, and the erection cost is high.

Welding with semi-automatic carbon dioxide welding or automatic welding equipment figure 1 The butt welds 5 between the webs 2 of the middle hatch coaming and the deep penetration or full penetration fillet welds 6 of the T-shaped joints between the webs 2 and the main deck 3, but for automatic welding equipment, a few meters of scaffolding There are uprights and beams, and the uprights and beams must be installed close to the inner side of the web due to safety factors. The uprights and beams of the traditional scaffolding become obstacles to the walking of the automatic welding trolley, and ordinary welding trolleys cannot achieve welding across obstacles

In addition, the general welding trolley is absorbed by magnets on the smooth surface of the inner side of the upper hatch coaming web, lacking a firm fulcrum support, affected by the heat of the welding process, the magnetic adsorption force decreases with the increase of temperature, and the track is easy to slip or even fall. fall, causing the position of the welding torch to deviate from the groove or fall and cause safety accidents
