Abstract

The utility model relates to a traction hook, in particular to a traction hook for a plane traction device. The traction hook for the plane traction device comprises an outer layer clamp plate, an inner layer clamp plate, a hook and a spring bolt positioning mechanism. The track hook for the plane traction device simplifies the structure of the traction hook by means of combined connection mode, solves the problem that traction hook material selection and machining are difficult, effectively reduces weight of the traction hook and improves operational flexibility of the traction hook. The spring bolt positioning mechanism has the advantages of being simple in structure, convenient to operate, safe and highly reliable.

Description

A kind of aircraft draw gear is linked up with traction

Technical field

The utility model relates to a kind of traction hook, and especially a kind of aircraft draw gear is linked up with traction.

Background technology

Effective connecting length of aircraft nose towing axle is longer, and the axis of traction diameter is very large, if the traction hook structure adopts single piece, processing technology is complicated, productive costs is high, and its volume and weight is all very large, ground crew's operation during inconvenient towing aircraft; Simultaneously, the stop gear of traction hook adopts the moving tommy bar mechanism controls latch bolt position of tetrad, and part is more, complex structure, and matching requirements are higher, and reliability is relatively low.

The utility model content

Technical problem to be solved in the utility model is: the aircraft draw gear that provide a kind of compound type to connect, processing is simple, easy to operate, use safety, reliability is high is with drawing hook.

The technical solution of the utility model is: a kind of aircraft draw gear is linked up with traction, it is characterized in that: described traction hook comprises outer laminated plank 2, interior laminated plank 1, hook 4 and dead bolt stop gear 3; Outer laminated plank 2 is fixing by bolt and nut 5 with interior laminated plank 1; Hook 4 is fixing by bolt and nut 5 with outer laminated plank 2; Dead bolt stop gear 3 is comprised of rotating shaft 10, dead bolt 11, handle 7, permanent seat 9 and locating dowel pin 8; Hook is divided into hook gib head and hook coupler body, has slot in the hook coupler body; Dead bolt 11 is positioned at the hook slot; Upper outside laminated plank, dead bolt 11, lower outside laminated plank are passed in rotating shaft 10 successively, and dead bolt 11 and rotating shaft 10 are by being welded and fixed; Handle 7 is positioned at upper outside laminated plank top and fixing with rotating shaft 10; Locating dowel pin 8 passes handle, locating dowel pin 8 lower ends with contact above the upper outside laminated plank.

The beneficial effects of the utility model are: the utility model connects by compound type, simplified the version of traction hook, solve traction hook selection and the large problem of difficulty of processing, effectively alleviated the weight of traction hook, improved the flexibility of operation of traction hook; The dead bolt stop gear is simple in structure, easy to operate, safety, and reliability is high.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.

Referring to Fig. 1, Fig. 2, the utility model aircraft draw gear comprises interior laminated plank 1, outer laminated plank 2, dead bolt stop gear 3, hook 4, bolt and nut 5, turning shear bolt 6 with a kind of specific embodiment of traction hook; Wherein the structure of dead bolt stop gear comprises handle 7, locating dowel pin 8, permanent seat 9, rotating shaft 10, dead bolt 11 referring to Fig. 3.

By two outer laminated planks 2 up and down and hook by six bolt and nuts clampings, be fixed together, outer laminated plank is connected by bolt and nut 5, turning shear bolt 6 with interior laminated plank 1 as the extension of hook, form the structure of combined traction hook, be provided with the turning safety device of traction hook.

With reference to Fig. 3, dead bolt 11 is passed in the rotating shaft 10 of dead bolt stop gear, and fixes by spot welding, and the initial installation site of dead bolt 11 should be with the position of outer laminated plank 2 upper lock tongue stop gears 3, coordinate the installation site of outer laminated plank 2 up and down, fixedly the position of dead bolt.

The utility model aircraft draw gear is linked up with when assembling with traction, the rotating shaft of dead bolt stop gear, bolt component are inserted in the mounting hole of two outer laminated planks 2 up and down, fix six bolt and nuts 5, then permanent seat 9 and the handle 7 of dead bolt stop gear 3 are installed, are guaranteed that the rotation of dead bolt stop gear 3 is flexible.

The utility model belongs to the part of aircraft draw gear, is connected with draw gear by interior laminated plank 1; During use, dead bolt stop gear 3 is pulled initial position by handle 7, dead bolt 11 is regained, then lift hook 4 and hang on the aircraft axis of traction, pull handle 7 to locked position, make dead bolt 11 gears below the aircraft axis of traction, and fixing with locating dowel pin 8.

The utility model selection commonality is high, and processing is simple, easily implements, and is easy to operate, improved the use alerting ability of traction hook, and the towing aircraft safe reliability is high.

The utility model is not limit the traction hook that is applicable to each large and medium-sized aircraft draw gear of domestic active service, and the compound type design philosophy can inspire the decomposition design of heavy parts, and the dead bolt stop gear can be applied in all kinds of mechanical equipments.
