Description

Technical Field

[0001] This invention relates to the field of mobile structure technology, specifically to an integral mobile structure for a helicopter. Background Technology

[0002] The outstanding characteristics of helicopters are their ability to perform low-altitude, low-speed maneuvering with a constant nose direction, and especially their ability to take off and land vertically in small areas. These characteristics give them a wide range of applications and development prospects. In military applications, they are widely used for ground attack, amphibious assault, weapons transport, logistical support, battlefield medical evacuation, reconnaissance patrols, command and control, communications, anti-submarine warfare, mine clearance, and electronic warfare. In civilian applications, they are used for short-haul transport, medical evacuation, disaster relief and rescue, emergency rescue, equipment hoisting, geological exploration, forest fire fighting, and aerial photography. The transport of personnel and supplies between offshore oil wells and bases is an important aspect of civilian applications, and helicopters with skid-tube landing gear are a diverse category.

[0003] When existing helicopters use skid-tube landing gear, rapid helicopter movement becomes an urgent problem to be solved. Using trailers or hoists would impose significant limitations on equipment and space. Therefore, an integrated helicopter movement structure is proposed to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an overall mobile structure for helicopters.

The first baffle has a first through hole and a second through hole. A locking bolt is inserted into the second through hole, and a locking nut is threaded to the other end of the locking bolt. After the spindle is fixed to the first baffle with a fixing rivet, it is then fixed to the skid tube with the locking bolt and locking nut to form a component. The connecting shaft is inserted into the spindle, enabling the quick installation of the transport wheels. By adding transport wheels to this device, short-distance helicopter relocation can be achieved, avoiding the inconvenience of helicopter movement when using skid tube landing gear, and reducing the site's restrictions on helicopter movement.

[0035] A limiting ring 10 is fixedly connected to the mandrel 201. The limiting ring 10 has two fixing holes 11, which are respectively located on the left and right sides of the front of the limiting ring 10. The fixing rivet 9 passes through the interior of the fixing hole 11. The limiting ring 10 can limit the two ends of the mandrel 201, so that the mandrel 201 can be stably set between the first baffle 1 and the second baffle 4. The fixing holes 11 can facilitate the installation of the mandrel 201 on the first baffle 1 by the fixing rivet 9.

[0036] There are two limiting rings 10, which are fixedly connected to the left and right ends of the outer wall of the spindle 201, respectively. The two limiting rings 10 can conveniently limit the two ends of the spindle 201.

[0037] The spindle 201 has a second positioning hole 205. A connecting shaft 12 is inserted into the spindle 201. A bearing 7 is fixedly installed inside the transport wheel 8.

The connecting shaft 12 is inserted into the inside of the spindle 201, realizing the quick installation of the transport wheel 8. By adding the transport wheel 8 to this device, short-distance helicopter relocation can be achieved, avoiding the inconvenience of helicopter movement when using skid tube landing gear, reducing the site's restrictions on helicopter movement. The design of the handle 304... The device allows the user to easily pull the connecting rod 303, causing the positioning pin 307 to disengage from the insertion hole 13 inside the connecting shaft 12. At this time, the connecting shaft 12 can be directly pulled out from inside the spindle 201, allowing for quick disassembly of the transport wheel 8. When it is necessary to install the transport wheel 8, the connecting shaft 12 is inserted into the spindle 201, and the positioning pin 307 is released so that it is inserted into the insertion hole 13 under the action of the spring 306, thereby achieving quick installation and fixation of the transport wheel 8 and further improving the practicality of the overall moving structure.
