Embodiment Construction
[0023] Such as Figure 1-2 The shown main tow bar 2 has a structure as follows: a front tow bar 1 is arranged on the nose landing gear of the aircraft, the front tow bar 1 includes a main pipe 1-1, and the buffer 1-2 is arranged on the main pipe 1-1. 1, the other end of the buffer 1-2 is connected with the traction ring 1-4 through the shear bolt 1-3, and the lifting mechanism 1-5 is connected with the hydraulic device 1-6 and one end of the main pipe 1-1. On the main pipe 1-1, the other end is connected to the cylinder 1-8 at the bottom of the bracket 1-7. The hydraulic device 1-6 drives the piston 1-8-4 on the cylinder to move to push the bracket 1-7 to the bracket. The fixed point is the center of rotation.
[0024] Lifting mechanism 1-5 such as image 3 As shown, actuators 1-8 are as Figure 4 As shown, the hydraulic device 1-6 includes an oil tank 1-6-1, one section of the hand pump 1-6-2 is connected to the oil tank 1-6-1, and the other end is connected to the oil tan...

The invention provides an airplane draw bar device. A main takeoff draw bar is arranged on an airplane main landing gear, and a front takeoff draw bar is arranged on an airplane nose landing gear. The airplane draw bar device adopts the structure that the front takeoff draw bar is arranged on the airplane nose landing gear, the front takeoff draw bar comprises a main pipe, a buffer is arranged at the front end of the main pipe, the other end of the buffer is connected with a traction ring through a shear bolt, a lifting mechanism consists of a hydraulic device arranged on the main pipe and an actuating cylinder of which one end is connected to the main pipe and the other end is connected to a support, and the hydraulic device drives a piston rod on the actuating cylinder to move so as to push the support to rotate by taking a support fixing point as the center. Through the adoption of the structure that the main takeoff draw bar and the front takeoff draw bar are arranged, the technical problems in the prior art that an airplane is inflexible in movement, a strong traction force has high probability of damaging the landing gears of the airplane and up-and-down adjustment of the draw bars is inconvenient are solved.
Description
technical field [0001] The invention relates to a towing device, in particular to an aircraft tow bar device. Background technique [0002] Before the 1990s, the drawbar equipment of military aircraft at home and abroad, because of the light weight of the aircraft and the small size of the aircraft, the structure of the drawbar is a single truss rod structure, which is simple in structure and light in weight. load. After the 1990s, the combat aircraft equipped by the air and naval forces of various countries greatly surpassed the military aircraft in the past no matter the overall size of the aircraft or the weight of the aircraft. Due to the changes in the structural form of the aircraft landing gear pillars, the aircraft is equipped with various high-precision electronic equipment and fire control equipment that have strict requirements on aircraft traction. Therefore, the frame-type towing bar in the past can no longer meet the towing work requirements of the aircraft. ...
