Description

Technical Field

[0001] This utility model relates to the field of transfer vehicle technology, specifically to a transfer vehicle for main reducer accessories. Background Technology

[0002] The helicopter main gearbox has a power input end for the engine and a power output end connected to the drive shafts of the rotor and tail rotor accessories. It is one of the main transmission components on the helicopter, and also the most complex, largest, and most important component in the transmission system. The helicopter main gearbox is generally a gear-driven main gearbox. Its working characteristics are deceleration and steering. It transforms the high-speed, low-torque engine power into low-speed, high-torque power to be transmitted to the rotor shaft, and then transmits the power to the tail rotor, accessories, etc., according to the speed and torque requirements. When the helicopter main gearbox is assembled in the factory, various parts need to be transported to the assembly line using a transfer vehicle. However, the existing transfer vehicles generally only have a top-level shelf, resulting in a small transport capacity. This leads to frequent transports by the transfer personnel, high labor intensity, and easy fatigue for the transfer personnel. Utility Model Content

[0025] The frame 1 is assembled from a top long beam, a top short beam, uprights, a bottom long beam, and a bottom short beam using die-cast brackets and countersunk screws. A back beam 11 is fixed between the two uprights on the rear side of the frame 1. Two drawer beams 10 are provided between the two uprights on the left side and the two uprights on the right side of the frame 1. A top reinforcing rib 12 is provided between the two top long beams of the frame 1. A bottom reinforcing rib 13 is provided between the two bottom long beams of the frame 1. Insertion slots are provided on the top long beam, top short beam, bottom long beam, and bottom short beam.

[0026] The middle part of the layer of the pattern plate 3 is fixed to the top reinforcing rib 12, and the periphery of the layer of the pattern plate 3 is located in the insertion slots on the top long beam and the top short beam of the frame 1.

[0027] The bottom storage plate 8 is fixed in the middle to the bottom reinforcing rib 13, and the bottom storage plate 8 is located in the insertion slots on the bottom long beam and bottom short beam of the frame 1.

[0028] The drawer structure includes drawer 5, padding strip 15 between the long beam of drawer 5, and heavy-duty industrial lockable drawer slide 14 on the side of the short beam of drawer 5. The slide of the heavy-duty industrial lockable drawer slide 14 is fixed on the drawer beam 10. The slide lock on the heavy-duty industrial lockable drawer slide 14 extends 10mm out of the slide. Both the long beam and the short beam of drawer 5 are provided with mounting grooves.

[0029] The middle portions of the two-layer storage plate 4 and the three-layer trace plate 6 are respectively fixed on the corresponding pads 15, and the two-layer storage plate 4 and the three-layer trace plate 6 are respectively inserted into the corresponding mounting slots around their perimeters.

[0030] The first layer of the trace plate 3 is composed of a first upper plate 18 and a first lower plate 19. The first upper plate 18 and the first lower plate 19 are fixed together by a male and female nail. The first upper plate 18 is provided with a pre-dug cavity 16 stamped according to the shape of the accessory. The bottom side of the pre-dug cavity 16 is provided with a coding label 17 corresponding to the pre-dug cavity 16. The coding label 17 is laser printed on the first upper plate 18. The first lower plate 19 is provided with a second pre-dug cavity that matches the pre-dug cavity 16.

[0031] The three-layer trace plate 6 is composed of a second upper plate 20 and a second lower plate 21.
