Embodiment 1

[0035] Embodiment 1 of the present invention provides a tool for measuring the height of a half-circle plate of a leg rack and chord tube. In order to facilitate the description of the measurement tooling provided by the embodiment of the present invention, firstly combine figure 1 Briefly introduce the structure of leg rack chord. like figure 1 As shown, the leg rack chord includes a rack 30 and semicircular plates 40 symmetrically welded on both sides of the rack 30 .

[0036] figure 1 It is a schematic diagram of the front view structure of a leg rack chord semi-circular plate height measuring tool provided by Embodiment 1 of the present invention. like figure 1 As shown, the measuring fixture includes a standard plate 10 and a measuring assembly 20 connected to the standard plate 10 . The standard plate 10 has a straight side 11 and the straight side 11 defines an opening slot 12 for accommodating the semicircular plate 40 . During implementation, the standard plate 1...

Embodiment 2

[0052] Embodiment 2 of the present invention provides a method for measuring the height of the leg rack chord semicircular plate using the measuring tool provided in Embodiment 1. figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Image 6 , the method includes:

[0053] The second base frame 210 in the measurement assembly 20 is rotated to be fixed with the fourth base 211, and the right-angle scale plate 26 passes through the open slot 12 and is connected to the first base frame 23 through the sliding groove 26a and the first slider 23b, The right-angle scale plate 26 is located in the first through groove 23b;

[0054] Rotate the support sleeve 25 so that the support rod 24 is extended or shortened to adjust the position of the right-angle scale plate 26, so that the hypotenuse 26b of the right-angle scale plate 26 is in contact with the opening groove 12, and the right-angle side of the right-angle scale plate 26 is in contact with the standard plate 10 vert...

Embodiment 3

[0060] Embodiment 3 of the present invention provides a method of using the measuring tool provided in Embodiment 1 to check whether the height of the leg rack chord tube semicircular plate is qualified. figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , the method includes:

[0061] The right-angled scale plate 26 passes through the opening slot 12 and is connected to the first base frame 23 and the second base frame 210 through the chute 26a, the first slider 23b, and the second slider, and the right-angled scale plate 26 is located in the first through groove 23a and in the second through groove;

[0062] Rotate the support sleeve 25 so that the support rod 24 is extended or shortened to adjust the position of the right-angle scale plate 26, so that the hypotenuse 26b of the right-angle scale plate 26 is in contact with the opening groove 12, and the right-angle side of the right-angle scale plate 26 is in contact with the standard plate 10 vertical;

Abstract

The invention discloses a tool and method for measuring the height of the semicircular plate of a leg chord, and belongs to the field of ocean engineering equipment. The measuring tool includes a standard plate and a measuring module connected with the standard plate; the standard plate has a straight side, the straight side of the standard plate is provided with an opening groove which can hold the semicircular plate; the measuring module comprises a first base and a second base which are fixedly disposed on a side of the standard plate, a first base frame, a support rod hinged to the middle of the first base frame, a support sleeve and a right-angle scale plate in threaded connection to the support rod and movably connected to the second base; one end of the base frame is hinged to the first base; a first slide block is disposed on the sidewall of a first slot at the other end of the first base frame; the right-angle scale plate is located in the first slot and is provided with a chute for the first slide block to slide, and the hypotenuse of the right-angle scale plate is provided with scale values equal to the height value of the hypotenuse. The tool may accurately measure the height of the semicircular plate.

Description

technical field [0001] The invention relates to the field of ocean engineering equipment, in particular to a tool for measuring the height of a leg rack and a chord tube semicircular plate and a measuring method. Background technique [0002] The jack-up offshore platform is the main equipment for marine engineering development at present. When the platform is operating, the legs not only have to bear the gravity of the offshore platform itself, but also are impacted by seawater. At present, the structural form of pile legs mostly adopts truss type. [0003] The truss-type pile leg includes at least three rack chords and connecting rods connected between the rack chords, wherein the rack chord consists of a rack and semicircular plates welded symmetrically on both sides of the rack. The core part of the truss-type pile leg, so the manufacturing accuracy of the rack chord will directly affect the performance of the pile leg, and it is very important to measure the rack chord...
