Description

Technical Field

[0001] This utility model belongs to the field of aviation auxiliary equipment technology, and relates to an auxiliary aircraft accessory parking, lifting and self-locking transportation device, specifically a comprehensive device that integrates parking and maintenance, short-distance transfer and lifting after the radar dome is disassembled. Background Technology

[0002] After disassembly, the radome of a certain type of aircraft needs to be transferred over a short distance (from the finished product site to the maintenance site). A special protective coating is applied to the radome's surface. Furthermore, the radome needs to be secured, and after transfer, it undergoes repair. Following repair, adjustments are required at a height between 1076mm and 1347mm from the ground to facilitate assembly. During the lifting and assembly adjustment process, vertical movement is not permitted. The radome's shape (larger at one end and smaller at the other) and overall arc shape mean that it is currently typically placed flat on a general-purpose flatbed truck. There is a lack of dedicated radome parking equipment, making it difficult to secure the product, protect the coating, and assist in assembly. Insecure securing and unstable vertical adjustments can easily damage the product, thus affecting the efficiency of thermal maintenance for the entire aircraft. Utility Model Content

[0003] This utility model provides an auxiliary aircraft accessory parking, lifting, and self-locking transport device. It is a comprehensive transport device that can quickly, stably, flexibly, and safely (with 40,000-way casters and foot brakes) effectively fix, park, transfer, lift, and self-lock a certain type of aircraft radome. It is lightweight, flexible in transfer, and quick in lifting (based on the characteristics of the front and rear double threaded columns, the two columns can be simultaneously raised and lowered, or raised and lowered on one side to achieve assembly angle adjustment). It can achieve dual protection of the product coating and the body. It is simple and quick to operate and meets the needs of multiple scenarios such as parking, transfer, maintenance, and assembly adjustment.

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

[0005] A self-locking transport device for parking and lifting auxiliary aircraft accessories, the transport device comprising a front bracket 1, a rear bracket 2, a sleeve handwheel 3, a one-way thrust bearing 4, a rear stop bar 5, a vehicle body 6, and a brake caster 7.

[0006] The vehicle body 6 is a frame structure with a square bottom frame and caster base plates fixed at the four corners for fixing and installing brake casters 7. The bottom frame has two parallel and symmetrically arranged triangular frames, and a connecting rod is fixed between the two triangular frames to form an integral frame. Reinforcing ribs are provided at the connection between the triangular frames and the bottom frame to increase strength. Each of the two triangular frames has a wheel nut 18 installed at the top. Each wheel nut 18 has a recessed groove at the top and a semi-circular protrusion on the inner wall of the top of the groove.

[0007] The sleeve handwheel 3 includes a handwheel wrench 15, a handwheel nut 16, and a handwheel support rod 17. The lower outer circumference of the handwheel nut 16 has a groove. The handwheel wrench 15 is a ring wrapped around the handwheel nut 16. The handwheel support rod 17 is welded between the two to form an integral assembly. To improve welding performance, all materials are made of 20 steel and then galvanized. There are two sets of sleeve handwheels 3. The lower end face of the two handwheel nuts 16 is fitted with the one-way thrust bearing 4 and then respectively installed into the grooves of the two wheel nuts 18 on the top of the vehicle body 6. The groove of the handwheel nut 16 and the semi-circular arc boss of the wheel nut 18 cooperate to form a limit.

[0008] The front bracket 1 and rear bracket 2 have the same structure and can be set to different sizes according to the supported products. Both include straps 9, strap fixing plates 10, bracket heads 11, bracket head pads 12, bracket swivel rods 13, and wooden supports 14. The bracket head 11 is fixed with wooden supports 14 by self-tapping screws. The top of the wooden supports 14 is set in an arc shape to fit the supported products. Straps fixing plates 10 are installed on both sides of the bracket head 11. Straps 9 are installed on the strap fixing plates 10 to fix the supported products. The bracket head pads 12 are fixed at the bottom center of the bracket head 11. The upper end of the bracket swivel rod 13 is fixed on the bracket head pads 12, and the lower end is assembled in the combined handwheel nut 16, one-way thrust bearing 4, and machine wheel nut 18 to realize the vertical lifting and self-locking of the front and rear brackets. The two brackets can be lifted and lowered synchronously or independently.

[0009] The rear stop bar 5 is welded from a stop bar screw and a stop bar wrench. After forming, it is covered with a stop bar rubber handle for easy manual lifting. The rear stop bar 5 cooperates with the front bracket 1 and is used to clamp laterally when the front bracket 1 is raised or lowered to the usage size, so as to achieve mechanical fixation.

[0010] Furthermore, the wheel nut 18 has a hole drilled in its side wall and a tail rod nut 19 is installed to cooperate with the installation of the wing nut 8. Tightening the wing nut 8 strengthens the locking of the bracket rotating rod 13.

[0011] The beneficial effects of this utility model are as follows: This utility model has a simple and practical structure, enabling rapid fixation of the radome for disassembly, relocation, repair, adjustment, and assembly, improving the efficiency of thermal protection maintenance and reducing damage. The transport device is lightweight, flexible in relocation, and features dual protection from the product coating and the main body. It is simple and quick to operate, providing strong on-site support for regular overhauls, major repairs, and thermal protection of the radome. Attached Figure Description
