Embodiment Construction
[0039] Figure 1~Figure 17 Among them, the low-temperature liquefied natural gas tank suit frame has a rail car 1, a horizontal rectangular frame 2 on the rail car, a rail wheel 3 under the frame, and a rotating frame 4, a side shifting frame 5 and a moving idler connected in sequence above the frame rack 6,
[0040] In the middle of the frame, there is a central shaft hole 7 perpendicular to the plane of the frame. In the middle of the bottom of the rotating frame, there is a central shaft 8 inserted in the central shaft hole. Fan-shaped slides with the central shaft hole as the center are evenly distributed on the top of the frame. 9. There is a fan-shaped roller group 10 on the bottom of the rotating frame that matches the fan-shaped slideway on the frame, and a rotating hydraulic cylinder 11 that can drive the rotating frame to rotate around the central axis is hinged between the frame and the rotating frame.
[0041] Horizontal lateral slides 12 are evenly distributed ab...

The invention provides a sheathing bracket of a low-temperature liquefied natural gas tank, wherein a rotation supporting frame, a side sway frame and a moving roller frame are successively connected on the rectangular car frame of a rail car; a fan-shaped slideway is arranged on the car frame; a set of fan-shaped rolls are arranged below the rotation frame; a hydraulic cylinder is hinged between the car frame and the rotation frame; a lateral slideway is arranged on the rotation frame; a set of parallel sector rolls are arranged below the side sway frame; a hydraulic cylinder is connected between the rotation supporting frame and the side sway frame; a supporting roller side slideway is arranged on the side sway frame; a supporting roller frame is arranged on the supporting roller side slideway; a set of parallel sector rolls are arranged below the supporting roller frame; and a hydraulic cylinder is connected between the side sway frame and the supporting roller frame. The sheathing bracket for low temperature liquefied natural gas tank disclosed by the invention has a rotation frame, a side sway frame and a moving roller frame driven by hydraulic pressure; when the cylinder body of an outer tank body is sheathed outside an inner tank body, the rotation frame, the side sway frame and the moving roller frame can move correspondingly under the driving force of the hydraulic pressure, therefore, the axis of the outer tank cylinder and that of the inner tank body is on the same line, and the working efficiency is high, the working quality is good and the labor intensity is low.
Description
technical field [0001] The invention relates to an auxiliary device for making a low-temperature liquefied natural gas tank, in particular to a low-temperature liquefied natural gas tank suiting frame. Background technique [0002] Natural gas is a kind of energy with good comprehensive performance. The volume of natural gas of the same mass is 600 times the volume of liquefied natural gas. In order to facilitate transportation and storage, natural gas should be made into liquefied natural gas. [0003] Liquefied natural gas (LNG) is a liquefied natural gas produced from gaseous natural gas under a certain pressure using cryogenic technology. [0004] When transporting liquefied natural gas by vehicle, the liquefied natural gas is contained in a low-temperature liquefied natural gas tank. Cryogenic liquefied natural gas tanks must ensure that the temperature of the liquefied natural gas in the tank is minus 162°C to minus 196°C, and the pressure is between 0.65Mpa and 1....
