Abstract
The utility model relates to a special tooling for integrally heating and automatically welding main coil pipes of pile legs of a marine drilling platform. The special tooling is characterized by comprising a pair of clamping plates which are symmetrically arranged in the vertical direction, wherein concave arc-shaped grooves capable of being exactly combined with string tubes in an embedded manner are arranged in the inner side surfaces of the clamping plates; upper connecting plates and lower connecting plates are respectively arranged at the upper ends and the lower ends of the clamping plates; two or more bolt connecting holes are arranged in the upper and lower connecting plates along the horizontal direction; and corresponding upper connecting plates of the two clamping plates can be connected and fixed through bolt groups, and corresponding lower connecting plates of the two clamping plates can be connected and fixed through bolt groups. A rack and the string tubes are clamped through the clamping plates in a plurality of special toolings and are connected and fixed through the bolt groups, so the positioning is realized, relative fixation of the positions of the rack and the string tubes is guaranteed during the welding, the welding quality is improved and the tooling is simple in structure.
Description
Technical field
The utility model relates to a kind of marine drilling platform spud leg master coil processing tool, particularly the whole heating of a kind of marine drilling platform spud leg master coil automatic welding special tooling.
Background technology
Along with the quickening of ocean development paces, the development prospect of marine engineering equipment industry is more and more wide.In the marine engineering equipment industry, the technical merit of drilling platforms is the highest, its ocean platform spud leg master coil is the critical component of self-lifting type marine drilling platform, its structure as shown in Figure 1, 2, 3, mainly comprise the tooth bar 1 at middle part and the semicircle string pipe 2 of tooth bar 1 both sides, string pipe 2 is welded and fixed with tooth bar 1, and product has that bearing load is large, dimension precision requirement is high, the large characteristics of welding difficulty, makes difficulty.
At present domestic traditional spud leg master coil during fabrication, string pipe and rack welding great majority employing stick electrode arc weldings exist welding efficiency low, welder's labour intensity is large, specification requirement is high, welding precision is difficult to control, poor working environment, the shortcomings such as production cost height.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of whole heating of marine drilling platform spud leg master coil automatic welding special tooling that can improve welding effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: the whole heating of a kind of marine drilling platform spud leg master coil automatic welding special tooling, its innovative point is: comprise a pair of vertical direction and symmetrically arranged clamping plate, the medial surface of described clamping plate be provided with just can be chimeric with the string pipe the arcs of recesses groove, clamping plate upper, the lower end is respectively arranged with upper junction plate and lower connecting plate, upper, along continuous straight runs is provided with two or more bolt connecting holes on the lower connecting plate, can be connected and fixed by the bolt group respectively between upper junction plate corresponding to two clamping plates and between the corresponding lower connecting plate.
The utility model has the advantage of: clamp tooth bar chord pipe by the clamping plate in some special toolings, and be connected and fixed by the bolt group, realize the location, it is relatively fixing to guarantee to weld hour rack chord pipe position, improves welding quality, and tool structure is simple.The problems such as it is large to have solved traditional manufacturing technique labour intensity, and product percent of pass is low are for the production of pile legs of self-elevating drilling platform master coil provides a kind of effective, practical frock of manufacturing.
