Problems solved by technology

The problem is that due to the high structural strength requirements of the drilling platform, there are strict requirements on the dimensional accuracy of each part of the pile leg structure. Starting with the dimensional relationship and the influence of each construction process on the dimensional accuracy, we will develop a method for segmental data detection of pile legs

Embodiment Construction

[0015] The segmental data detection method of the large-scale truss-type pile legs of the present invention includes the detection of the main dimensions of the pile legs, wherein:

[0016] a. The length L1 of the leg segment is detected by the distance between the two ends of the leg segment-main side tube (as shown in Figure 1);

[0017] b. The leg segment height H1 is detected through the vertical distance from the main side tube to the opposite surface of the leg segment (that is, the distance from the center point of the end of the main side tube to the opposite surface of the leg segment) (as shown in Figure 2);

[0018] c On the cross section, the distances Z1, Z2 and Z3 from the rack plate to the segmented center of the leg are detected through the distance from the center point of the main side tube end to the center of the segmented equilateral triangle of the opposite leg (as shown in Figure 2);

[0019] d Detect the rack plate spacing B1, B2, B3 (as shown in Figure...

Abstract

The invention discloses a method for performing a measurement to the size of the triangle truss type spud leg and the local precision during the process of constructing a jack up drilling platform, wherein, the large scale truss type spud leg segmenting data detecting method of the invention comprises the detecting procedures that: the main size of the spud leg is detected; the main size of the spud leg comprises a spud leg segmenting length (L1), a spud leg segmenting height (H1), a distance from a gear rack plate to a spud leg (Z1, Z2 and Z3), and a gear rack plate space (B1, B2, B3); the levelness of the gear rack plate and the crown of the gear rack plate end face are detected; the middle point (P5) of an end part gear rack central line is fetched to detect the same face degree of the gear rack plate. The invention has the advantages that the invention is convenient and advisable and has high detection precision, under the support of a high precision instrument, the exact dimensional accuracy, a tolerance and a derivation can be obtained, thereby guiding a construction process, guaranteeing the quality of the final drilling platform, reducing the possibility of the platform damage, and ensuring the safety of an offshore operation.

Description

technical field [0001] The invention relates to a method for detecting the local dimensional accuracy of a frame-type frame body, more specifically, relates to a method for measuring the size, local accuracy and deviation of triangular truss-type pile legs used to build a self-elevating drilling platform Methods. Background technique [0002] The Chinese patent "Composite tire frame device for segmental construction of pile legs" filed by the applicant on December 8, 2006 describes a composite tire frame device for segmental construction of pile legs. This paper describes the leg structure of the jack-up drilling platform. The leg shape is a triangular truss type, and the three corners of the leg structure are provided with a main side tube with a rack, which is connected by a support tube, including two opposite semicircular tubes and a part with a rack (or called rack plate), connected by structural tubes to form a triangular truss. The problem is that due to the high s...
