Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
In the description of the present invention, unless otherwise specified and limited, it should be noted that term " installation ", " connected ",
" connection " shall be understood in a broad sense, for example, it may be mechanical connection or electrical connection, the connection being also possible to inside two elements can
It, can also be indirectly connected through an intermediary to be to be connected directly.It for the ordinary skill in the art, can basis
Concrete condition understands the concrete meaning invention of above-mentioned term.
Referring to the embodiment of the present invention described in Fig. 1 to Fig. 3
A kind of rack gear spreading tooling for truss-like marine drilling platform main side tube of spud leg, every set rack gear spreading tooling include 2
A wedge shape frame 1 and 4 tension device 2, each wedge shape frame 1 is welded on plate frame 11 by two wedge blocks 12 to be formed,
The outer back gauge of 12 transverse gage of wedge block is no more than spline thicknesses, and the welding that longitudinal center's distance adds 2.0 ~ 2.5 mm is shunk
Amount；The tension device 2 is welded on 22 both ends of flower basket bolt by plate folder 21 and is formed；The plate at tension device both ends presss from both sides 21 pre-slottings
Mouthful, it is embedded in 1 edge of wedge-shaped frame and is fixed；When 3 spreading of spud leg main side pipe racks, 2 wedge-shaped frames 1 are respectively loaded on to interface
Locate the upper and lower cut surface of rack gear 3,2 tension devices 2 are respectively arranged in 3 two sides of rack gear, by tightening flower basket bolt 22 for upper and lower two
Wedge-shaped frame 1 tenses, and completes the quick positioning of 3 spreading of rack gear.
Preferably, the positioning of 3 spreading of rack gear finishes, the gaily decorated basket can be adjusted according to practical contraction distortion situation in welding process
Bolt 22 it is elastic, thus control welding shrink and side bending deformation, guarantee rack gear spreading precision.
Preferably, main side tube of spud leg semi-circular plate 4 is arranged in spud leg main side pipe racks 3.
Flower basket bolt two end plates folder 21 of the invention is welded on 22 both ends of flower basket bolt and forms tension device 2, welding point
