Embodiment 1

[0040] like Figure 1~4 As shown, a kind of auxiliary equipment for helicopter ground movement, including heavy gear train 1, hydraulic system 2 and frame 3. The heavy-duty wheel system 1 includes a heavy-duty tire 101 and a wheel axle 102. Two identical heavy-duty tires 101 are respectively installed on the two ends of the long axis of the wheel axle 102, and a pair of first trunnions are set on the wheel axle 102 between the two heavy-duty tires 101. 103, the first trunnion 103 is provided with four evenly distributed bolt holes;

[0041] The hydraulic system 2 includes a hydraulic jack 201. The bottom of the hydraulic jack 201 is provided with four evenly distributed countersunk holes 202. The countersunk holes 202 are adapted to the bolt holes on the first trunnion 103, and the hexagon socket bolts pass through the countersunk heads in turn. The hole 202 and said bolt hole fix the bottom of the hydraulic jack 201 on the first trunnion 103;

[0042]The frame 3 includes a ...

Embodiment 2

[0044] Such as figure 2 with image 3 As shown, further on the basis of Embodiment 1, an auxiliary device for ground movement of a helicopter, the support frame 301 is in the shape of an inverted U, and the inverted U-shaped support frame 301 is covered on the hydraulic jack 201 . The screw rod at the top of the hydraulic jack 201 is provided with a blind hole 203, and the center position of the top of the support frame 301 is provided with a through hole. The bolt assembly 313 passes through the through hole on the support frame 301 and the blind hole at the top of the hydraulic jack 201 successively, and the support frame 301 tops are fixedly connected with hydraulic jack 201 tops. The opposite side walls of the inverted U-shaped support frame 301 are respectively provided with an inverted U-shaped groove 304 , and the axle 102 passes through the inverted U-shaped grooves 304 on the side walls of the inverted U-shaped support frame 301 in sequence.

[0045] The hydraulic ...

Embodiment 3

[0047] Such as figure 2 with image 3 As shown, further on the basis of Embodiment 2, a kind of auxiliary equipment for helicopter ground movement, the bottom of the support frame 301 and the fixed block 302 are connected and fixed through the bottom plate 303:

[0048] The bottom surface of the support frame 301 and the fixed block 302 are all provided with bolt holes, and the bottom plate 303 is provided with countersunk holes that match the bolt holes on the bottom surface of the support frame 301 and the fixed block 302. The support frame 301, the bottom plate 303 and the fixed block 302 are sequentially It is connected by bolt 306, and the bolt adopts hexagon socket bolt;

[0049] The upper surface of the fixed block 302 is provided with two symmetrical second trunnions 307, and the center of the second trunnions 307 is provided with a through hole; the opposite side walls of the bottom plate 303 are provided with two symmetrical third trunnions ( 308) and a blind hole...

Abstract

The invention discloses an auxiliary equipment for helicopter ground movement, which comprises a heavy-duty wheel train, a hydraulic system and a frame; the heavy-duty wheel train includes heavy-duty tires and a wheel shaft, and the heavy-duty tires are installed at both ends of the long axis of the wheel shaft. And the first trunnion is provided on the axle; the hydraulic system includes a hydraulic jack, and the bottom of the hydraulic jack is fixed on the first trunnion; the frame includes a support frame and a fixed block, and the support The upper part of the frame is connected with the top of the hydraulic jack, and the bottom of the support frame is connected with the fixed block. The support frame drives the fixed block to move up or down with the hydraulic jack, and the fixed block is used to fix the helicopter stand. The helicopter ground movement auxiliary device provided by the invention has a compact overall structure, a small overall volume, convenient storage and transportation, and is economical and practical.

Description

technical field [0001] The invention relates to the technical field of general aviation, in particular to an auxiliary device for ground movement of a helicopter. Background technique [0002] During the ground movement of the helicopter, it is the basic requirement of the ground handling work to transfer the helicopter quickly, conveniently and efficiently. Research, design and manufacture of helicopter transfer mechanism is an effective way to improve the efficiency of ground operations; at the same time, it also shortens labor time and reduces labor intensity for ground personnel. Currently commonly used helicopter ground mobile devices mainly include integrated and combined types. The integrated type is a ground mobile device in which the traction device and the helicopter carrying device are integrated. The method is to park the helicopter on the integrated ground mobile device and directly carry the helicopter. Ground movement; the combined type is to separate the tra...
