Description

Technical Field

[0001] This utility model belongs to the field of aircraft parts transportation technology, and relates to a temporary aircraft tire transportation device. Background Technology

[0002] A certain type of aircraft has three tires. Due to the large size of the tires (approximately 1600mm in diameter) and their heavy weight (approximately 150kg), temporary transport is difficult for a single person (without handles or connecting parts). Typically, multiple people working together with general-purpose tooling are used. There is a lack of dedicated temporary tire transport equipment. Furthermore, placing the tires upright on a flatbed requires at least two people to support them, and placing them upside down easily wears down the wheel rims, exhibiting instability and a tendency to roll. Considering the characteristics of thermal support, including tight deadlines, urgent tasks, personnel shortages, lack of dedicated tooling, and operational difficulties, existing methods cannot meet the requirements. Utility Model Content

[0003] To fill the gap in the temporary transportation and parking of tires for a certain type of aircraft, this utility model provides an aircraft tire transportation device, specifically a pull-out double-bend "horn-shaped" temporary transportation device that is ready to use upon insertion. It integrates stretchability, load-bearing capacity, and transportability, with a simple structure and convenient operation. It is the best choice for thermal protection maintenance and repair. Furthermore, due to the versatility of tires, this device can be extended to the transportation of general tires for automobiles, ships, and other types of vehicles.

[0004] The present invention adopts the following technical solution:

[0005] A temporary transport device for aircraft tires, the temporary transport device comprising a handle mechanism 1, a locking structure 2, a baffle mechanism 3, a base frame mechanism 4, and polyurethane directional casters 8.

[0006] The base frame mechanism 4 includes a pedal 20, a vertical rod 21, a support plate 22, and a support rib 23. The support plate 22 has support ribs 23 fixedly installed at both ends. The support ribs 23 are arc-shaped and double-bent "ox horn" shaped, which can be directly inserted into the bottom of the arc surface on both sides of the tire to support the tire. The vertical rod 21 is a hollow column and is fixedly installed in the middle of the upper surface of the support plate 22. A hole is made in the upper part of the vertical rod, and a locking structure 2 is installed in the hole. The pedal 20 is installed in the middle of the side of the support plate 22 away from the support rib 23.

[0007] The polyurethane directional casters 8 are installed at both ends of the lower surface of the support plate 22.

[0008] The handle mechanism 1 includes a handle grip 10, a handle vertical rod 11, a vertical rod pad 12, and a handle base plate 13. The handle grip 10 and the handle vertical rod 11 are fixedly connected to form a T-shaped structure. The handle grip 10 is covered with a rubber grip 7. The handle vertical rod 11 has several connecting holes spaced apart, which are inserted into the vertical rod 21 on the base frame mechanism 4. The handle mechanism 1 is pulled out to the required height, and locking is achieved by the locking structure 2 cooperating with the corresponding connecting holes. The handle vertical rod 11 is fixed with a vertical rod pad 12, and the bottom is fixed with a handle base plate 13 to increase strength.

[0009] The locking structure 2 includes a rotating handle 14, a threaded rod 15, a pressure plate 16, a cylinder 17, and a spring 18. One end of the cylinder 17 is fitted with the pressure plate 16, which has a central circular hole. The other end has an annular boss on its inner wall. The spring 18 is placed inside the cylinder 17, with one end pressed against the end face of the pressure plate 16 and the other end fixed to an annular fixing plate. The fixing plate presses against the annular boss of the cylinder 17. One end of the threaded rod 15 is threadedly fixed to the rotating handle 14, and the other end passes through the pressure plate 16 and exits from the cylinder 17. The fixing plate of the spring 18 is fixed to the threaded rod 15. The cylinder 17 is fixedly installed in the hole at the top of the vertical rod 21 in the base frame mechanism 4. In its natural state, the end of the threaded rod 15 passes into the connecting hole on the handle vertical rod 11 in the handle mechanism 1, achieving height locking of the handle mechanism 1. Pulling the rotating handle 14 outward causes the end of the threaded rod 15 to disengage from the handle mechanism 1, adjusting the height of the handle mechanism 1.

[0010] The baffle mechanism 3 includes baffle pins 5, stainless steel hinges 9, baffle 19, and sealing plate 6. The baffle 19 is n-shaped, and its two ends are mounted on the support plate 22 in the base frame mechanism 4 facing the support rib 23 via stainless steel hinges 9, so that the baffle 19 can be adjusted in angle to press the tire tightly onto the support rib 23 and prevent the tire from falling off. The sealing plate 6 is fixedly installed on the top of the baffle 19 facing the vertical rod 21. The sealing plate 6 is provided with a number of positioning holes at intervals, and the hole spacing is set according to the outer diameter of the vertical rod 21. Two baffle pins 5 are inserted into two adjacent positioning holes to clamp the vertical rod 21 between the two baffle pins 5 to fix the baffle 19 at the required angle.

[0011] In use, the temporary transport device is in its natural state with the support rod 23 on the ground. The tire is loaded onto the support rod 23, the angle of the baffle 19 is adjusted to press the tire, the two baffle pins 5 are inserted to fix the angle of the baffle 19, the rotating handle 14 is pulled outward, the handle mechanism 1 is pulled out to the desired angle, the rotating handle 14 is released to fix the handle mechanism 1, the foot pedal 20 is stepped on and the handle lever 10 is pressed down to make the support rod 23 leave the ground, and the temporary transport device is pushed to transport the tire.

[0012] The beneficial effects of this utility model are: This utility model has a simple and practical structure, which can improve the transportation efficiency of aircraft tires after disassembly and before assembly, and shorten the overall equipment thermal protection cycle.
