Description

Technical Field

[0001] The invention belongs to the field of helicopter maintenance equipment, and in particular relates to a bracket device for disassembling and assembling a helicopter sighting system. Background Art

[0002] The sighting system is the "eyes" of the helicopter, which mainly uses television, laser, infrared, tracking equipment, etc. to search, aim, locate, measure distance and track targets. This system plays an increasingly important role in modern warfare, providing helicopters with powerful battlefield perception and precision strike capabilities.

[0003] The sighting and observation system is an important component of the helicopter's precision guidance system. It often requires maintenance and needs to be replaced or repaired when a failure occurs. Therefore, it often needs to be disassembled and installed.

[0004] The sighting and observation system is a cylinder with a spherical lower end. The structure is not conducive to human grasping and weighs dozens of kilograms. Currently, during the disassembly and installation process, multiple people are required to lift the sighting and observation system by hand. Because the disassembly and assembly process is long and the equipment is heavy, it is extremely inconvenient to disassemble and assemble. The sighting and observation system is extremely expensive, with the price of a single unit reaching several million yuan. Once accidentally damaged, the loss will be serious.

[0036] When installing a helicopter sighting system:

[0037] a1. Push the trailer carrying the helicopter sighting system to the bottom of the installation point of the helicopter sighting system, raise the connecting platform 8, and connect the helicopter sighting system to the helicopter fuselage;

[0038] b1. After the helicopter sighting system is connected to the fuselage, pull out the quick-release pins between the left support arm 11 and the right support arm 21 and the connecting platform 8, disconnect the left support arm 11 and the right support arm 21 from the connecting platform 8, lower the connecting platform 8, move the trolley out of the fuselage, and remove the left bracket 1 and the right bracket 2 from the helicopter sighting system for storage;

[0039] c1. Move the trailer to the parking spot. If the left bracket 1 and the right bracket 2 are not used in a short period of time, put the left bracket 1 and the right bracket 2 back into the packing box.

[0040] The present invention provides a bracket device for disassembling and assembling a helicopter sighting system. With the assistance of a towing vehicle, the helicopter sighting system is grabbed and carried for disassembly and assembly, thereby solving the inconvenience of manually lifting the helicopter sighting system when disassembling and assembling the helicopter sighting system, and preventing the helicopter sighting system from being damaged.

[0041] Anti-skid rubber pads 3 are provided on the curved surfaces of the left arm 12 and the right arm 22 .

[0042] A roller group is disposed on the upper and lower side walls of the first slide groove 13 and the second slide groove 23.

The light rod part 62 is hinged to the left arm 12, and the screw rod part 63 is threadedly matched with the left support arm 11. A hand wheel 61 is provided at the top of the adjusting rod 6. The hand wheel 61 controls the rotation of the adjusting rod 6. The adjusting rod 6 is used to fine-tune the height spacing between the left arm 12 and the left support arm 11, so as to facilitate the disassembly and assembly of the helicopter sighting system. The left bracket 1 and the right bracket 2 are symmetrically arranged, and the right support arm 21 and the right arm 22 are symmetrically arranged. Similarly, through the cooperation of the adjusting rod 6 and the guide column 7, when disassembling the helicopter sighting system, when the connecting platform 8 is close to the left bracket 1 and the right bracket 2, the lifting of the connecting platform 8 is stopped, and the height fine-tuning hand wheels 61 on the left bracket 1 and the right bracket 2 are synchronously rotated to perform height fine-tuning, so as to facilitate the alignment of the left support arm 11 and the right support arm 21 with the slide groove of the connecting platform 8; when installing the helicopter sighting system, when the helicopter sighting system is about to approach the installation point, the lifting speed of the connecting platform 8 is reduced, and the two hand wheels 61 are synchronously rotated to fine-tune the height of the left arm 12 and the right arm 22, so as to facilitate the alignment of the helicopter sighting system with the installation holes of the fuselage. After alignment, the helicopter sighting system is connected to the fuselage.
