Abstract
The utility model discloses a supporting frame which is provided with a supporting frame body, wherein the upper part of the supporting frame body is of a semicircular-arc structure matched with a rolled tube. The supporting frame body is of a frame-shaped steel structure formed by connecting a bottom plate, a longitudinal rib plate, a reinforcing rib plate, a side blanking plate, a top panel and a top semicircular panel. The supporting frame can be used for assisting a lifting-up system in finishing a lifting-up operation for a jacket rolled tube, and thus, the other lifting way is provided for the jacket rolled tube; the increased length and weight of a large rolled steel tube in a workshop are increased, and the lengthening operation for the large rolled tube in the workshop is realized; the welding quality for the large lengthened rolled steel tube is improved, the work efficiency for lengthening the large rolled steel tube is increased, and the safety for lifting the large rolled tube is improved; and the utilization ratio of a shop traveler in the workshop is reduced, and the building cost of the rolled tube is reduced.
Description
Technical field
The utility model relates to bracing or strutting arrangement, relates in particular to a kind of continuous jacking support frame of ultra-large type deep water jacket wrap-around tube structure that is applicable to.Belong to the offshore engineering field.
Background technology
Along with China's marine petroleum development constantly to the striding forward of deep water field, the large-sized deep water jacket has obtained using more and more widely.At present, for the steel pipe of the caliber of making jacket greater than 406mm, all adopt steel plate to roll and form, its pipe crimping process: at first, with the steel plate of specifying specification in the tubulation workshop, cut, blanking and roll into several little pipeline sections; Then, again several little pipeline sections are carried out the integral solder spreading to design length; Along with the increase of large-sized deep water jacket volume, roll the weight of steel pipe and length and also further increase, so that the part large-scale steel pipe is because of overhead traveling crane inadequacy of lifting capacity in the workshop, and the hauling operation after can not in the tubulation workshop, finishing spreading fully.Therefore, for the large-scale spreading work that rolls steel pipe, a spreading part in the workshop normally, then, the recycling overhead traveling crane with its be lifted into be transported to outside the workshop on the flat truck after, set up shed and proceed grafting.Mainly there is following shortcoming and outside the workshop, finish the large-scale steel pipe spreading that rolls:
1, the workshop external environment is subject to the Changes in weather impact, reduces the large-scale welding quality that rolls the steel pipe spreading;
2, the extra work such as scaffolding has increased laid down cost, has reduced work efficiency;
3, overhead traveling crane lifting operation efficient is low, and cost is high, makes the large-scale cycle that rolls the steel pipe spreading become large, has increased wrap-around tube laid down cost;
4, the overhead traveling crane lifting operation is subjected to the impact of center of gravity uncertain factor, has certain potential safety hazard.
The utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of support frame, it can be used for auxiliary jack-up system and finish the jacket wrap-around tube is carried out lifting operation, thereby a kind of another hoisting way to the jacket wrap-around tube is provided; Increased large-scale length and the weight that rolls steel pipe spreading in the workshop, realized all large-scale wrap-around tubes grafting in the workshop; Improved large-scale welding quality and the welding efficiency work efficiency that rolls the steel pipe spreading reached the safety that large-scale wrap-around tube is promoted; Reduced in the workshop the Occupation coefficient of overhead traveling crane, reduced the laid down cost of wrap-around tube.
The purpose of this utility model is realized by following technical scheme:
A kind of support frame is characterized in that: be provided with a support frame body, the semicircular arc structure of this support frame body top for matching with wrap-around tube.
Described support frame body is by base plate, vertical floor, strengthens the frame shape steel structure that the semicircle panel in gusset, sidepiece shrouding, top panel and top connects and composes.
The beneficial effects of the utility model: the utility model is simple in structure, and it can be used for auxiliary jack-up system and finish the jacket wrap-around tube is carried out lifting operation, thereby a kind of another hoisting way to the jacket wrap-around tube is provided; Increased large-scale length and the weight that rolls steel pipe spreading in the workshop, realized all large-scale wrap-around tubes grafting in the workshop; Improved large-scale welding quality and the welding efficiency work efficiency that rolls the steel pipe spreading reached the safety that large-scale wrap-around tube is promoted; Reduced in the workshop the Occupation coefficient of overhead traveling crane, reduced the laid down cost of wrap-around tube.

The specific embodiment
Such as Fig. 1-shown in Figure 4, the utility model is provided with a support frame body, the support frame body is mainly by base plate 1, vertically floor 2, all kinds of reinforcement gusset 3, sidepiece shrouding 4, top panel 5, the semicircle panel 6 in top and the frame shape steel structure that consists of that adopts welding manner to connect, the semicircular arc structure of the top of support frame for matching with wrap-around tube.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
Claims (2)
