[0032] The telescopic part 3 is connected to the lifting and lowering part 2. As the lifting and lowering part 2 moves up and down, the telescopic part 3 expands and contracts along the horizontal direction to match the installation position.

The fixed rod 422 is a Y-shaped structure, the bottom 4221 of its bifurcated end is welded to the chassis 421, and the upper part 4222 of the bifurcated end is connected to the rotating rod 423 through a fixed bolt 427. The top end of the rotating rod 423 is connected to the rotation mechanism 43, and the other end of the rotating rod 423 is connected to the adjustment lead screw structure 424 through a connecting rod 426. Driven by the adjustment lead screw structure 424, the rotating rod 423 moves relative to the fixed rod 422 with the fixed bolt 427 as the center point to change the pitching angle of the rotation mechanism. The front end of the lead screw of the adjustment lead screw structure 424 is connected to the connecting rod 426, and the end of the lead screw is driven by a motor and a reduction motor 428.

[0036] The rotation mechanism 43 is driven to rotate by a rotation motor 431, and the rotation mechanism 43 further drives the installation accessory part 6 provided thereon to rotate and adjust the angle left and right.

[0037] The deflection part 5 is provided on the pitching adjustment part 4. Since there are some differences in the distance and angle between the position of the installation machine and the bulkhead every time an insulating board is installed, the deflection part 5 can be used for small-amplitude deflection left and right after the insulating board is close to the installation position for fine adjustment, and the effective adjustment angle of the fine adjustment is ±15°.

[0038] See Figure 5A and Figure 5BAs shown, the deflection part 5 includes a third lead screw structure 51, a connecting plate 52, two side support plates 53, a rotating plate 54 and a supporting plate 55. Among them: The connecting plate 52 is connected to the surface of the rotating mechanism 43 of the pitching adjustment part, so that the deflection part 5 can move along with the pitching adjustment part 4. The two side support plates 53 are arranged on the upper surface of the connecting plate 52 to play a supporting role. The fixed end 511 of the lead screw of the third lead screw structure 51 is arranged between the two side support plates 53. The front end of the adjusting part 512 of the third lead screw structure passes through the fixed end 511 of the lead screw, and a manual adjustment handle 513 is arranged at the end of the adjusting part 512. A connecting bearing 541 is arranged at the bottom of the rotating plate 54, and the adjusting part 512 of the third lead screw structure 51 passes through the connecting bearing 541.

There is an operating gap between the frame body 62 and the upper surface of the fixing plate 61, and a plurality of row holes 63 are arranged on the frame body 62. The frame body 62 forms inclined surfaces at multiple angles. Setting the frame body 62 on the fixing plate 61 can be applicable to insulating boards of different shapes, not just flat insulating boards. The insulating board is locked on the row holes of the suitable inclined surface through bolts.

[0040] In addition, an electric control box 7 is equipped on the front side of the main rod. The electric control box 7 is located on the front side of the main rod to balance the entire main body part 1.

[0041] When this application is in use, first fix the insulating board on the row of holes of the installation accessory part 6 with bolts. Subsequently, the installer pushes the installation machine to the corresponding position where it needs to be installed, steps on the brakes of the universal wheels, and props up the foot support rod 125 to ensure the stability of the installation machine body. According to the installation position of the insulating board, use the wired control box or the remote control box to raise the first hydraulic cylinder to match the corresponding height; extend the second hydraulic cylinder to be close to the installation bulkhead; adjust the pitching adjustment part to make the glue application surface of the insulating board as parallel as possible to the bulkhead plane (if the matching with the bulkhead surface is not good, the pitching base can be rotated 90 degrees to the left or right by loosening the three bolts of the pitching base to meet different installation conditions); if there is a deviation between the current position of the installation machine and the actual position, the left and right positions can be adjusted by adjusting the screw rod adjustment handle; in order to facilitate hole alignment, it is necessary to first confirm the position of the screw holes on one side and then achieve alignment with the screw holes on the other side by deflecting left and right. Finally, during the process of the insulating board continuously approaching the bulkhead, make appropriate fine adjustments, install the insulating board in place according to the drawn auxiliary lines, and use bolts and gaskets as required to fix it firmly to complete the installation of the insulating board.

[0042] The installation machine of this application is applicable to the insulation layer in the LNG cargo containment system, and can cooperate with the installation of each insulating board weighing 300 - 400 kg faster, more accurately and more safely, avoiding contact between personnel and the insulating board, and reducing dust, moisture pollution or damage caused by personnel contacting the insulating board.
