Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a reinforcement of a fixed saddle for an LNG tank of a car carrier, a fixed saddle and a manufacturing method. Background Art

[0002] The LNG tank of the car carrier is cylindrical, and the structure needs to be designed with fixed reinforcements that match the LNG tank for installation. The LNG tank is large in size and weight, so a saddle is required at the bow and stern to bear its weight, one fixed saddle and one movable saddle to facilitate on-site lifting. The fixed saddle reinforcement needs to be connected to the baffle above the middle T-beam panel to prevent the saddle from deforming.

[0003] like Figure 1 As shown, the existing fixed saddle reinforcement has the following disadvantages:

[0004] 1. A circle of corresponding reinforcement is set on both sides of the central supporting T-beam, and the whole is made into a reinforcement with a slot connecting the baffle above the middle T-beam panel, which is difficult to position on site.

[0005] 2. The reinforced upper end of the fixed saddle is set at a right angle, but the temperature of the LNG tank is low and requires thicker insulation. The reinforced right angle will interfere with the insulation. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a reinforcement and manufacturing method of a fixed saddle for an LNG tank of a car carrier, which solves the difficulty of on-site hoisting and positioning and eliminates the problem of insulation interference.

[0007] The object of the present invention is achieved through the following technical solutions: a car carrier LNG tank fixed saddle reinforcement, comprising:

[0008] The middle supporting T beam, each of which has two ends connected to two triangular T beams.

[0009] The baffles are symmetrically arranged on the outer sides of the ribs.

[0010] Toggle plate, connecting the end of the baffle plate and the triangular T-beam panel.

[0011] A saddle reinforcement includes two symmetrically arranged intermediate supporting T-beams, four baffles and several brackets.

[0012] In addition to providing a saddle reinforcement, the present invention further provides a saddle provided with the saddle reinforcement, wherein the saddle reinforcement is arranged at a certain angle and at equal intervals below a horizontal line passing through the center of the tank body.

[0013] The present invention also provides a method for manufacturing a saddle reinforcement, which is as follows:

[0014] Step 1: Set the arrangement of the saddle reinforcement in the fixed saddle according to the overall layout and LNG tank parameters, and confirm the specific positioning of the saddle reinforcement;

[0015] Step 2: Determine the width of the intermediate support T-beam panel;

[0016] Step 3: Connect the T-beam panel and the corresponding structure at the lower end to determine the shape of each fixed saddle reinforcement structure.

[0017] Preferably, the saddle reinforcement positioning is confirmed by connecting the bottom longitudinal structure and the inner bottom through the intersection of the center of the tank body.

[0018] Preferably, if there is a corresponding structure at the saddle reinforcement position in the height direction, it needs to be consistent with the corresponding structure positioning.

[0019] Preferably, the width of the intermediate supporting T-beam panel is determined according to the LNG tank parameters.

[0020] Preferably, the toggle plate is rounded.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] The present invention provides a reinforcement, fixed saddle and manufacturing method for the LNG tank of a car carrier. When modeling and designing the triangular T-beam structure, a negative margin 2 can be placed when supporting the T-beam panel in the middle to facilitate on-site insertion, thereby solving the problem that the existing design cannot place a negative margin, is inconvenient to insert, and requires a lot of time to adjust the position on site. By adding a guide circle design to the elbow plate, the problem of the difficulty of on-site positioning of the fixed saddle reinforcement is fundamentally solved, and the situation of insulation interference with the tank body is eliminated. The present invention solves the on-site positioning problem and insulation interference problem of the fixed saddle, and can save a lot of time for hoisting, deformation adjustment, and later interference cutting and grinding.

[0029] Intermediate supporting T beams 1, each intermediate supporting T beam 1 is connected to two triangular T beams 4 at both ends;

[0030] Baffles 2 are symmetrically arranged on the outside of the middle supporting T beam 1;
