These structural forms lead to the weak bearing capacity and poor manufacturability of the existing raceway devices
Moreover, most of the existing raceway devices are tightly connected with the underfloor profiles or quickly released with the aircraft ground rail. The installation, disassembly and maintenance of the fastened connection method are difficult, and the quick release connection with the aircraft ground rail will cause excessive large incidental weight

Embodiment Construction
[0018] A kind of raceway device of the present invention is described in detail in conjunction with accompanying drawing:
[0019] Provide a raceway device, including a plurality of rolling rod assemblies 1, multiple pairs of seat codes, multiple pairs of card seats, one seat rail 4, and two locking devices 5; wherein, each rolling rod assembly includes a left retaining ring 6a , right retaining ring 6b, left steel wire retaining ring 7a, right steel wire retaining ring 7b, left roller bearing 8a, right roller bearing 8b, roller shell 9, roller shaft 10; each pair of seat codes includes left seat code 2a and right seat code 2b; each pair of decks includes left deck 3a and right deck 3b;
[0020] In each roller assembly 1, the roller shell 9 is a cylindrical aluminum alloy, and the outer wall surface of the cylinder is hard anodized; the roller shaft 10 is a stepped shaft structure with a thick middle part and thin ends. There are two symmetrical shaft shoulders, and both ends...

The invention belongs to the technical field of aviation and relates to a raceway device used for air transportation and air drop. The raceway device mainly comprises a seat rail, rolling rod assemblies, seat codes, clamp seats and locking devices. The rolling rod assemblies are composed of rolling rod shell bodies, rolling rod shafts, roller bearings, blocking rings and steel wire blocking rings, wherein the rolling rod shafts, the roller bearings, the blocking rings and the steel wire blocking rings are installed in the rolling rod shell bodies. The rolling rod shafts penetrate into shaft holes of the seat codes and then ride on the vertical faces of the two sides of the seat rail. The clamp seats are connected on the seat rail in a riveting mode, and spherical bulges of the clamp seats fall into concave holes of the seat codes to limit moving of the seat codes. The seat rail is sectioned and arranged reasonably, and the multiple rolling rod assemblies are installed on the seat rail. When working, the raceway device is rapidly fixed on an airplane floor through the locking device, and integrated packaging units are placed on the raceway device. When not working, the raceway device is dissembled from the airplane floor. The defects of poor bearing capacity, inconvenient dissembling and assembling, poor manufacturability and interchangeability and the like of a traditional raceway device are overcome.
Description
technical field [0001] The invention belongs to the technical field of aviation and relates to a raceway device used for air transport and air drop. Background technique [0002] The raceway device is mainly used for the support or linear transmission of the container unit in the air transportation and airdrop mission, and usually includes three parts: seat rail, rolling rod assembly and connecting piece. At present, most of the existing raceway seat rails are made of riveted angle materials and plates; the roller shafts are directly connected to the seat rails through cotter pins, balls or stop gaskets; most of the bearings are single-row needle roller bearings. These structural forms lead to weak bearing capacity and poor manufacturability of the existing raceway device. Moreover, most of the existing raceway devices are tightly connected with the underfloor profiles or quickly released with the aircraft ground rail. The installation, disassembly and maintenance of the fa...
