Abstract
The utility model relates to a special rescue traction hanger for an aircraft. The hanger mainly comprises traction cables, ring-shaped belts, an overload protection device, shackles and a pulley block, wherein both the traction cables and the ring-shaped belts are circular belts formed by twisting high-strength fiber, thereby having high strength and light weights; the ring-shaped belts cannot scratch the application cylinder of the landing gear of the aircraft; a safety pin in the overload protection device can be made with various specifications according to different types of aircrafts, thereby satisfying the requirements for utilization in various types of aircrafts in the conventional airport; and safety protection riggings are used for prevent a broken end of the safety pin from rebounding after the safety pin is broken; and the pulley block enables the force on the whole system to be balanced through the moving of the traction cable on a pulley. Therefore, the hanger has the advantages of compact structure, strong suitability, light weight and simplicity in operation, and can ensure that the whole aircraft is drawn to move smoothly and safely.
Description
Affiliated technical field
The utility model relates to a kind of traction hanger, and the accident aerocraft of being applicable to can not move voluntarily, needs to implement the emergent aerocraft rescue traction hanger that pulls the specialty of using when rescuing.
Background technology
Civil aircraft is the indispensable transport facility of the modern life, because it has the advantages that volume is big, weight is big.In a single day aerocraft loses ability voluntarily, need use traction appliance to pull separately.Being suitable for general hauling rope can not guarantee accident aerocraft safety be pulled, and blindly operation also possibly cause the damage of caring for the position.How not receiving under the further damage prerequisite at assurance accident aerocraft, the accident aerocraft of making obtains pulling the aerocraft rescue traction hanger that just needs specialty steadily, safely and solves.
Summary of the invention
In order to solve the problem that the accident aerocraft can access steadily, pull safely, the utility model provides a kind of later-model aerocraft rescue traction hanger.Its technical scheme is: this traction hanger is made up of tracting cable, endless belt, overload protection device, shackle and assembly pulley.Its tracting cable and endless belt are all the circle band that high-intensity fiber is entwined, and do not have rigid joint, and intensity is big, light weight, and the endless belt can be cared for easily on aerocraft alighting gear application cylinder, can not cause the scuffing to application cylinder; Overload protection device comprises safety device, safety pin and safety guard-safeguard rigging; Safety device is the device that is used to install safety pin; Safety pin divides plurality of specifications by type; Be the safety element that is used for limiting overload traction, the safety guard-safeguard rigging is the protection rigging that is used to prevent broken end resilience after the shear pin breakage; Shackle and assembly pulley are the coupling assemblings of each parts of connected system and breakdown trailer, and wherein assembly pulley makes total system reach stress balance through tracting cable moving on pulley.
This traction hanging tool structure is compact, and comformability is strong, and is in light weight, simple to operate.
The beneficial effect of the utility model is owing to use multinomial safety method in the system, can ensure that aerocraft is whole steadily, safety pulls.Through the conversion of different loads safety pin, can reach the operating needs that can satisfy the various types in existing airport once cover aerocraft rescue traction hanger in addition.
