As shown in fig. 1 to 13, the present embodiment provides a method for installing a C-tank saddle of a gas carrier, including:
installation of a fixed saddle:
s11: the fixed-side laminated wood outer contour line 111 is drawn.
Step S11 specifically includes:
s111: a C-shaped cargo tank symmetry line 101 is arranged at the bottom of the C-shaped cargo tank 100, and a first horizontal reference surface 102 is arranged at a position C away from the bottom of the C-shaped cargo tank 100;

s113: the outer contour line 111 of the fixed-side laminated wood 11 on the surface of the fixed-side laminated wood on the side away from the C-type cargo tank was drawn based on the measured data.
In this embodiment, the C-shaped cargo tank 100 is horizontally disposed, and the C-shaped cargo tank symmetry line 101 is disposed on the C-shaped cargo tank 100 by ocean-rushing. A rectangular coordinate system is established with the x-axis as the line of the first horizontal reference plane 102 opposite to the fixed-side laminated wood 11 and the y-axis as the line perpendicular to the first horizontal reference plane 102 as the origin o, and with the intersection point of the x-axis and the C-type cargo tank symmetry line 101 as the origin o. The distance from the surface of the fixed-side laminated wood 11 on the side close to the first horizontal reference plane 102 is measured every d distance from the o point in the direction of both sides of the x axis, and the coordinate value of this point is recorded. And recording coordinate values of all points through drawing software, and sequentially connecting all points through a curve so as to draw the outer contour line 111 of the laminated wood on the fixed side. In addition, the value of c ranges from 0 to 1000mm, the value of d ranges from 50 to 300mm, specifically, the value of c is 500mm, the value of d is 200mm, and CAD software is adopted as drawing software.
S12: a fixing-side epoxy outer contour line 171 located outside the fixing-side laminated wood outer contour line 111 and spaced a distance a from the fixing-side laminated wood outer contour line 111 is drawn.
In step S12, the C-tank symmetry line 101 points perpendicularly to the direction of the two sides of the C-tank 100, and the value of a gradually increases. Specifically, the change range of the a value is 10mm-20 mm. In this embodiment, since the opening of the fixing-side laminated wood outer contour line 111 is smaller than the diameter of the fixing-side laminated wood 11, and the fixing-side laminated wood can be smoothly fitted into the saddle, in designing the fixing-side epoxy resin outer contour line 171, the value of a gradually increases from the o point to both sides of the x axis, specifically, the value of a at the o point is 10mm, and the value of a at the opening of the fixing-side epoxy resin outer contour line 171 is 20 mm. At this time, the distance of the opening of the fixing side epoxy resin outline 171 is increased, and the problem of the locking when the fixing side laminated wood 11 is fitted into the saddle can be prevented, and it should be noted that the actual thickness of the fixing side epoxy resin 17 is 10 mm.

in the present embodiment, the fixed-side saddle restricts the movement of the C-type cargo tank 100 in the axial and circumferential directions of the C-type cargo tank 100, and therefore, the fixed-side bow and stern flaps 14 and 15 and the fixed-side saddle arc panel 13 are enclosed as a groove that restricts the movement of the fixed-side laminated wood 11 in the axial direction of the C-type cargo tank 100. And a fixed side sway-prevention flat iron 16 is further arranged in the groove, the fixed side laminated wood 11 is inserted into the fixed side sway-prevention flat iron 16, and the fixed side laminated wood 11 is limited to move along the circumferential direction of the C-shaped cargo tank 100.

A rectangular coordinate system is established with the x-axis as the line of the first horizontal reference plane 102 opposing the slide-side laminated wood 21 and the y-axis as the line perpendicular to the first horizontal reference plane 102 as the origin o at the intersection of the x-axis and the C-type cargo tank symmetry line 101. The distance from the surface of the slip-side laminated wood 21 on the side close to the first horizontal reference surface 102 is measured every d distance from the o point in the direction of both sides of the x axis, and the coordinate value of this point is recorded. The coordinate values of all the points are recorded through drawing software, and the points are connected in sequence through a curve, so that the outer contour line 211 of the laminated wood on the sliding side is drawn. In addition, the value of c ranges from 0 to 1000mm, the value of d ranges from 50 to 300mm, specifically, the value of c is 500mm, the value of d is 200mm, and CAD software is adopted as drawing software.

s27: a sliding side bow baffle 24, a sliding side stern baffle 25 and a sliding side sway prevention flat iron 26 opposite to a cabin symmetry line 201 of the cabin are arranged on the sliding side saddle arc-shaped panel 23 at intervals.
In the present embodiment, the sliding-side saddle restricts the circumferential movement of the C-type cargo tank 100 along the C-type cargo tank 100, allowing the axial movement of the C-type cargo tank 100 along the C-type cargo tank 100. First, the sliding-side laminated wood 21 includes a first laminated wood 212 and a second laminated wood 213, the first laminated wood 212 is fixedly connected to the C-type cargo tank 100, and the second laminated wood 213 is fixedly connected to the sliding saddle via the sliding-side epoxy resin 27. The sliding side bow baffle 24, the sliding side stern baffle 25 and the sliding side saddle arc-shaped panel 23 are enclosed into a groove, the second laminated wood 213 is filled in the groove, the sliding side sway-stopping flat iron 26 is inserted into the first laminated wood 212, and the first laminated wood 212 is abutted to the second laminated wood 213. Thus, the first laminated wood 212 and the second laminated wood 213 can slide axially relative to the C-type cargo tank 100, and the sliding side sway stop bars 26 limit the circumferential sliding of the first laminated wood 212 and the second laminated wood 213 relative to the C-type cargo tank 100. Specifically, the thickness of the second laminated wood 213 is greater than or equal to the depth of the groove. The sliding side sway-stopping flat iron 26 is provided with one and is opposite to the cabin symmetry line 201, the first laminated wood 212 is provided with an insertion groove, the insertion groove is opposite to the C-shaped cargo tank symmetry line 101 of the C-shaped cargo tank 100, and when the C-shaped cargo tank 100 is installed to the saddle, the sliding side sway-stopping flat iron 26 is inserted into the insertion groove.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
