Detailed Description

The present invention will be described in further detail below with reference to the accompanying drawings.

The novel tug wheel structure shown in fig. 1-4 comprises a helicopter undercarriage cross bar 1, a tug wheel structure 2 and a mounting device 3, and is characterized in that the mounting device 3 is fixedly mounted on the helicopter undercarriage cross bar 1, a clamping groove 31 is formed in one side of the mounting device 3, the tug wheel structure 2 comprises a connecting structure 21 and a pull rod 26, the connecting structure 21 comprises a plurality of mounting plates 22, a first cross beam 23, a second cross beam 24 and a third cross beam 25 are respectively and fixedly connected to the mounting plates 22, the first cross beam 23 is matched with the clamping groove 31, the pull rod 26 is fixedly connected to the second cross beam 24 in a welding manner, a clamping hook 27 is arranged at one end of the pull rod 26 far away from the second cross beam 24, the clamping hook 27 can be clamped with the helicopter undercarriage cross bar 1, and rollers 28 are respectively mounted at two ends of the third cross beam 25, the rollers 28 are respectively positioned on two sides of the helicopter landing gear cross bar 1, and the pull rod 26 is positioned above the third cross beam 25.

Preferably, the upper edge of the mounting device 3 is provided with a threaded through hole 32, and the threaded through hole 32 is provided with a threaded rod 33. The mounting plate 22 is triangular in shape. The pull rod 26 is connected with a clamping hook 27 in a penetrating mode, the clamping hook 27 can rotate on the pull rod 26, 2 clamping rings 29 are fixedly arranged on the pull rod 26 in a welding mode, and the clamping rings 29 are located on two sides of the clamping hook 27 respectively.
