Embodiment Construction

[0012] Below in conjunction with accompanying drawing this embodiment will be further described

[0013] Depend on figure 1 It can be seen that one end of the herringbone rod mechanism 10 is connected with the body through a joint bearing, and the other end is connected with the lifting platform 6 through a torque sensing mechanism 11 . The two ends of the pull-down rod mechanism 9 are respectively connected with the body and the lifting platform 6 through joint bearings. The stop wheel mechanism 7 is connected with the lifting platform 6 by a pin shaft, and is driven by an oil cylinder connected by the same pin shaft. The two ends of the lifting oil cylinder 5 are connected with the body and the lifting platform 6 through joint bearings. The telescopic arm 3 is connected to the lifting platform through pads, and is driven by a telescopic arm cylinder. The folding arm mechanism 1 is connected with the telescopic arm 3 through a pin shaft and driven by a folding arm oil cyli...

Abstract

The invention provides a device for protecting a nose landing gear of a rodless aircraft tractor. The device is mainly characterized in that a herringbone pull rod mechanism is connected with a machine body by knuckle bearings; the other end of the herringbone pull rod mechanism is connected with a lifting platform by a torque sensing mechanism; the two ends of a lower pull rod mechanism are respectively connected with the machine body and the lifting platform by the knuckle bearings; an aircraft wheel retaining mechanism is connected with the lifting platform by pin shafts; the two ends of a lifting cylinder are connected with the machine body and the lifting platform by the knuckle bearings; retractable arms are connected with the lifting platform by cushion blocks; arm folding mechanisms are connected with the retractable arms by the pin shafts and are driven through an arm folding cylinder between the arm folding mechanisms and the retractable arms; pin plugging mechanisms are connected with the arm folding mechanisms by bolts; and ground contact wheels are connected with the lifting platform by the pin shafts and baffle plates. The device has the advantages that when the aircrafts of the category listed in the application range of the rodless aircraft tractor are dragged and pushed, the nose landing gear of the aircraft is protected reliably, and the problem that the damage to the nose landing gear of the aircraft and the heavy economic loss are uncertain to avoid when various functions and performance parameters of the rodless aircraft tractor are detected is solved.

Description

technical field [0001] The invention relates to a rodless aircraft tractor, in particular to a rodless aircraft tractor with a protective aircraft front landing gear system. Background technique [0002] At present, domestically produced aircraft tractors are all rodless aircraft tractors, which are an era behind international rodless aircraft tractors, and several rodless aircraft tractors that have been trial-produced in China do not have aircraft nose landing gear protection systems. It cannot be realized by dragging the real machine test. Simultaneously, it is impossible to test the aircraft produced by foreign aircraft frame manufacturers one by one for all ten or twenty types of aircraft in the scope of use. Contents of the invention [0003] The object of the present invention is to provide a front landing gear protection device for a rodless aircraft tractor aiming at the deficiencies in the above-mentioned technologies. When towing and pushing the types of aircr...
