Description
Technical Field
[0001] The utility model relates to the technical field of flatness detection of insulation boards of LNG ships, in particular to an insulation board step difference detection device. Background Art
[0002] The insulation board is laid inside the LNG cargo tank. Adjacent insulation boards are connected with glue. Tooling is required to detect the height difference between adjacent insulation boards and whether the joint is flat. By performing height detection during the installation of adjacent insulation boards, the installation height error of adjacent insulation boards can be kept within a reasonable range. Existing height detection tooling mostly uses a roller to mark the surface of the wooden floor to detect the flatness of the wooden floor. The roller marking partition is the concave deformation area of the wooden floor. The marking branch chain is used to drip a pigment solution on the wooden floor to indicate that the area is the protruding deformation area of the wooden floor, so that the deformation area on the surface of the wooden floor can be intuitively found. However, for newly laid insulation boards, it is necessary to quickly detect the height difference between adjacent insulation boards to determine the flatness of the insulation board. The existing detection tooling needs to frequently adjust the rolling position of the roller. After the device is shifted, it can only detect adjacent insulation boards in the straight direction. When detecting the joint of the insulation board, there are problems such as cumbersome steps, long time consumption and low detection efficiency. For this reason, we propose an insulation board step difference inspection device. Utility Model Content

[0028] Working principle: When in use, the gap alignment window 4 provided with the gap line can be aligned with the connection gap of the four insulating plates 19, so that the projection center of the horizontal plate 1 and the output end of the stepper motor 8 in the horizontal direction is located at the connection of one end of the four insulating plates 19.

The force sensor 13 synchronously drives the force sensing wings 14 on both sides thereof to rotate synchronously, and the bottom surface of the force sensing wing 14 is aligned with the bottom surface of the horizontal plane. The surfaces are coplanar. When the force sensing wing 14 rotates, if there is a height difference between different insulating plates 19 that exceeds the error range, the side of the insulating plate 19 with a higher height will apply thrust to the force sensing wing 14 in contact with it. The force sensor 13 will transmit the fluctuating value to the central processing unit through the signal amplifier, and the central processing unit will transmit it to the numerical display screen 16 and the terminal display screen in the hands of the inspector for display. The inspector can infer whether the height difference is within the error range based on the detected value. If it exceeds the preset value, the insulating plate 19 to be adjusted can be quickly determined.
