Description

Ground towing machine wheel of skid type helicopter
Technical field
The present invention relates to a kind of ground towing machine wheel that is used for small-sized skid type helicopter transportation.
Background technology
The main pattern of helicopter landing gear has two kinds of wheeled and sledge formulas.The helicopter that adopts wheel undercarriage generally needs the special tractor truck that is equipped with to transport when carrying out short-distance transportation or transition, has therefore increased maintenance task, has improved maintenance cost.And the alighting gear of skid chassis helicopter is the ripping bar of two symmetries; Self does not have ground tractive capacity, need carry out ground traction transportation the time for this reason, needs to install the fluid pressure type towing machine wheel of specialty or uses supporting lifting transport trolley to carry out ground traction haul; So inconvenient operation, cost is higher.
Particularly for small-sized skid type helicopter, like sled formula unmanned plane because such helicopter body weight is less, when therefore shifting as still with the fluid pressure type towing machine wheel with lift transport trolley and transport, its complicated operation, cost is higher, practicality is not good enough.
Summary of the invention
The object of the invention:, the invention provides a kind of convenient transportation, skid type helicopter simple to operate, lower-cost ground tugboat in order to solve prior art skid type helicopter short-distance transportation inconvenience, complicated operation, cost problem of higher
Technical scheme of the present invention: a kind of helicopter ground towing machine wheel, it comprises base, wheel, rotating shaft, neonychium, wherein; Said base bottom is provided with the passage that rotating shaft is installed, and said wheel is arranged on the rotating shaft two ends, and is locked in the base both sides through nut; Said base be provided with one be used to accommodate ripping bar U type groove, and said neonychium is arranged in the said U type groove, simultaneously; Two walls of said U type groove are symmetrically arranged with a transverse groove and vertical slots; The neonychium of this position also is provided with corresponding transverse groove and vertical slots, and wherein, said transverse groove bottom should be not more than on the ripping bar distance between two adjacent fixed pins to the distance between the vertical slots.
Said neonychium is bonding to be arranged in the U type groove of base.
Said neonychium is rubber pad or rubber washer.
Advantage of the present invention is: U type groove and helicopter ripping bar on the ground towing machine wheel of skid type helicopter base of the present invention match, and particularly transverse groove and the vertical slots through U type groove inwall can install and fix ripping bar quickly and easily.When therefore carrying out short-distance transportation; Can the helicopter ripping bar be directly installed in the base U type groove, then through traction ground towing machine wheel transport helicopter easily, and during dismounting; Only need raise the helicopter ripping bar; The set pin of ripping bar is separated with vertical slots with the transverse groove of base U type groove, can realize separating of helicopter and ground towing machine wheel, therefore simple to operation.And skid type helicopter of the present invention ground tugboat is simple in structure, and cost is lower, is highly suitable for the short range traction transportation of Mini Tele-Copter, has certain actual application value.

The specific embodiment
Through the specific embodiment the present invention is further specified below:
See also Fig. 1, it is the structural representation of skid type helicopter one preferred embodiments of the present invention.In this embodiment, said ground towing machine wheel of skid type helicopter comprises base 1, wheel 2, bearing 3, neonychium 4.Wherein, said base 1 bottom is provided with the passage 5 that bearing 3 is installed, and said wheel 2 is arranged on bearing 3 two ends, and is locked in base 1 both sides through nut.Said base 1 be provided with one be used to accommodate ripping bar 6 U type groove 7.Said neonychium 4 is rubber pad or rubber washer, is bonded in said U type groove 7 inboards through adhesive, to reduce the wearing and tearing between ripping bar 6 and the U type groove 7.
Please consult Fig. 2 simultaneously, it is the lateral plan of base among Fig. 1, and two walls of said U type groove 7 are symmetrically arranged with a transverse groove 8 and vertical slots 9.Wherein, Installation and removal between ripping bar and the base for ease; Said transverse groove bottom is not more than on the ripping bar 6 distance between two adjacent fixed pins to the distance between the vertical slots, and the opening part size of transverse groove 8 and vertical slots 9 should be less than the diameter of ripping bar set pin.Simultaneously, the neonychium 4 of transverse groove and vertical slots position also is provided with corresponding transverse groove and vertical slots, is installed on the U type groove 7 so that the ripping bar set pin passes neonychium 4.
In addition, Fig. 3 is the base A-A cutaway view among Fig. 2,1 inner passage 5 of base described in the figure be positioned at U type groove 7 below be used to install bearing 3.
See also Fig. 4, it is the assembling scheme drawing of ground towing machine wheel of skid type helicopter one preferred embodiments of the present invention.The actual commentaries on classics joined in the process, lifts a side ripping bar 6 about 20cm earlier, and inclined base 1 makes transverse groove 8 aim at the set pin of ripping bar 6 then, base 1 and set pin is in place along transverse groove 8 again.Rotating base 1 then, makes ripping bar 6 another set pins aim at base vertical slots 9, and is in place, and then falls ripping bar.In like manner, opposite side ripping bar 6 is installed, to realize the assembling between helicopter ripping bar and the base 1 according to above step.
Transverse groove and the vertical slots of ground towing machine wheel of skid type helicopter of the present invention in sum through the U type groove inwall on the base be Assembly &Disassembly helicopter ripping bar quickly and easily.When therefore carrying out short-distance transportation; Can the helicopter ripping bar be directly installed in the base U type groove, then through traction ground towing machine wheel transport helicopter easily, and during dismounting; Only need raise the helicopter ripping bar; The set pin of ripping bar is separated with vertical slots with the transverse groove of base U type groove, can realize separating of helicopter and ground towing machine wheel, therefore simple to operation.And skid type helicopter of the present invention ground tugboat is simple in structure, and cost is lower, is highly suitable for the short range traction transportation of Mini Tele-Copter, has certain actual application value.
