Embodiment Construction
[0021] The specific implementation of the aircraft emergency rescue device of the present invention will be described below according to the accompanying drawings.
[0022] Aircraft emergency rescue device of the present invention such as figure 1 As shown, the overall combined structure design is adopted, including a traction rod 1, a hydraulic lifting system 2, a support platform 3, a traveling mechanism 4 and a wheel holding mechanism 5. The traction rod 1 is used for traction to move this device, and the front end of the traction rod 1 has a T-shaped handle that is convenient to hold hard, and the rear end is as Figure 5 As shown, the pin shaft is hinged on the cross bar 32 in the support platform 3, and the traction rod 1 can rotate left and right with the pin shaft as the fulcrum. The hinged structure of the traction rod 1 and the support platform 3 adopts a quick connection type, and is fixed by a steel ball spring quick release pin. spring pin 11 as Figure 5 As sh...

The invention provides an emergency rescue device for an airplane. The emergency rescue device comprises a traction rod 1, a hydraulic lifting system 2, a support platform 3, a traveling mechanism 4 and a wheel holding mechanism 5, wherein the platform surface of the support platform 3 is C-shaped; a universal support wheel 33 is arranged on the front end of each of two prongs 3; the support platform 3 is connected with the traction rod 1 through a hinging structure; the hydraulic lifting system 2 comprises an oil pump 21, a high-pressure oil pipe 22, a hydraulic cylinder 23 and a connecting rod mechanism 24, wherein the connecting rod mechanism 24 is arranged on the rear ends of the two prongs of the support platform 3; the connecting rod mechanism 24 is connected with the traveling mechanism 4 and is used for converting a horizontal pushing force of the hydraulic cylinder into a downward pushing force of a main axle through a lever principle, so that the traveling mechanism 4 moves downwards, and the lifting of the support platform 3 is realized; wheel holding brackets of the wheel holding mechanism 5 are arranged on the platform surface of the support platform 3 and used for stably holding wheels to effectively prevent the wheels from sliding off, and thus the connection reliability of the emergency rescue device and the wheels of the airplane is ensured in a dragging process. The emergency rescue device provided by the invention has the effect of simple structure and is easy to operate.
Description
technical field [0001] The invention relates to an aircraft emergency rescue device, in particular to an aircraft emergency rescue device used to replace a tire burst or locked wheel to enable the aircraft to move when the tire is blown or the wheel is locked due to accidents during take-off, taxiing and landing of the aircraft . Background technique [0002] As an aircraft emergency rescue device, at present, airports at home and abroad generally use wheeled aircraft tractors as equipment for towing aircraft. However, the tractor is bulky, inconvenient to operate, expensive and difficult to maintain. As for the common small-sized equipment that is used to replace the fire-locked machine wheel with a flat tire, there is no mature product with simple structure and easy to use both at home and abroad. [0003] The object of the present invention is to provide an aircraft emergency rescue device with simple structure, easy maintenance, ground crews can independently complete ...
