[0002] IRST (Aircraft Infrared Search and Tracking System Front Sensor), also known as optical mine sensor, uses the principle of single photon detection technology to greatly improve the sensitivity of the sensor. Daily inspection and maintenance of such high-precision equipment is a very important task. The first step of regular inspection and maintenance is to remove the optical mine sensor from the aircraft. At present, there is no equipment for such work tasks on the market. The general method of the army is to directly remove the optical mine sensor with special tooling and then manually lift it onto a trailer for transportation.

[0003] Problems with existing technologies:

[0004] The optical radar sensor is directly disassembled using special tooling and then manually lifted onto a trailer for transportation. This type of disassembly and assembly method has low efficiency, requires 3 to 4 people to work together, is complex to operate, and is greatly affected by human factors during the disassembly and assembly process, posing certain risks. Utility Model Content

[0005] In view of this, the utility model provides an auxiliary disassembly and assembly device for a light mine sensor to solve the problems of low working efficiency, need for cooperation of multiple people and complex operation in the existing light mine sensor assembly method.

The device moves the lifting device and the supporting device to the bottom of the light mine sensor, and then drives the bottom plate to rise through the lifting device.

First, the two bolts at the diagonal angles of the light mine sensor are removed to leave two bolt holes on the light mine sensor. Then, the distance between the bottom plate 1 on the X-axis and the Y-axis is adjusted by rotating the first screw and the second screw 23 so that the two plug columns 5 can be aligned with the light mine sensor. The two bolt holes are inserted into the two bolt holes, and then the two plug posts 5 are driven up by the scissor-type lift 21 to be inserted into the two bolt holes. After the support rod 4 supports the two bolt holes, the ratchet wrench 7 is rotated. The screw rod 6 rotates and drives the support plate 8 to rise until the sensor is supported, and then the remaining bolts are removed. After the disassembly is completed, the threaded rod 17 is rotated in the opposite direction to drive the tightening disc 18 to rise, and the limit on the chassis 15 is released. Then the sensor on the support plate 8 is driven down by the scissor-type lift, and finally, it is transferred to the next maintenance work area.
