Abstract
The utility model provides a helicopter dragging wheel which comprises a first rolling wheel, a second rolling wheel, and a dragging device which is arranged between the first rolling wheel and the second rolling wheel, wherein the dragging device comprises a main body; the main body is internally provided with an oil pump, an integrated block, a rack shaft, a gear shaft, a cavity, an oil storage barrel, and a safe handle and a ventilation plug which are arranged on the cavity body; and the helicopter dragging wheel also comprises a rocker seat which is fixedly connected with the oil pump, and a handle which is connected with the rocker arm. The helicopter dragging wheel solves the technical problems that the dragging wheel has a complex structure, leaks oil easily, and is great in manufacturing difficulty and poor in manufacturability; a hydraulic oil pipeline of the dragging wheel is arranged in the middle oil storage barrel, the complex sealing structure is avoided, the probability of outward hydraulic oil leakage is reduced, and as the part structure is simple, the use is reliable, and the processing manufacturability is good.
Description
Technical field
The utility model belongs to helicopter ground handling equipment technical field, is specifically related to a kind of helicopter towing machine wheel.
Background technology
In recent years,, keep and formation fighting capacity, improve the usefulness of safeguarding of equipment, realize that the quick and convenient of flight-line service seems extremely important along with helicopter equips our troops successively in batches.The helicopter landing device of little tonnage adopts ski type, relies on the Sledge type support to prop when parking, and is when moving helicopter during routine maintenance, mobile again after needing a kind of device that it is held up.And existing towing machine wheel is that hydraulic circuit is designed on dynamic component, and is in motion, very high to the hydraulic circuit seal request during owing to dynamic component work, needs a large amount of sealing members, thereby the design of part complicacy, easy leakage of oil, and difficulty of processing is big, and manufacturability is poor.
The utility model content
In order to solve the towing machine wheel complex structure, leakage of oil easily, and difficulty of processing is big and the technical matters of manufacturability difference, and the utility model provides a kind of helicopter towing machine wheel.
The technical scheme that the utility model adopts: a kind of helicopter towing machine wheel comprises first roller, second roller; Be arranged at the machine that drags between first roller and second roller, it is characterized in that: the said machine that drags comprises main body, is provided with oil pump in the said main body; Integrated package, rack shaft, gear wheel shaft; Cavity, oil drum is arranged at safety handle and breather stem vent plug on the cavity; Also comprise the rocker arm bracket that is connected with oil pump, with rocker arm bracket bonded assembly handle.
Preferably, the lower end of said main body is provided with claw.
Preferably, said main body is provided with handle.
Preferably, said claw is provided with torsion spring.
Preferably, said integrated package is provided with unloader valve.
The utility model advantage compared with prior art:
1, this device can guarantee that not only the safe helicopter with several tons of weights holds up, and can also easily it be dragged to repair location, and volume is little, and is in light weight, carries when being convenient to army's transition training.
2, the towing machine wheel hydraulic circuit is installed in the oil drum of middle part, has avoided complicated hermetically-sealed construction, has reduced the possibility that hydraulic oil leaks, because design of part is simple, therefore uses reliably, and fabrication properties is good.

Description of reference numerals:
The specific embodiment
Referring to Fig. 1-shown in Figure 2, the helicopter towing machine wheel that the utility model provides comprises first roller, 1, the second roller 2; Be arranged at and drag machine 3 between first roller 1 and second roller 2, drag machine 3 to comprise main body 301, be provided with oil pump 311 in the main body 301; Integrated package 321, rack shaft 331, gear wheel shaft 341; Cavity 351, oil drum 381 is arranged at safety handle 361 and breather stem vent plug 371 on the cavity 351; The rocker arm bracket 302 that drags machine 3 also to comprise to be connected with oil pump 301 is with rocker arm bracket 302 bonded assembly handles 303.The lower end of main body 301 also is provided with claw 4.Main body 301 is provided with handle 5, and claw 4 is provided with torsion spring 6.
The principle of work of the utility model is following:
The claw 4 of towing machine wheel is connected with fastening nail on the helicopter Sledge type support; Shake the handle 303 on the rocker arm bracket 302; Drive oil pump 311 work, hydraulic oil promotes rack shaft 331 through integrated package 321, and the gear wheel shaft 341 that is engaged with is rotated; Thereby the relative position that changes first roller 1 and second roller 2 is raised towing machine wheel claw 4, the purpose that realization holds up whole helicopter.Unloader valve 3211 is housed on the integrated package 321, and when load surpassed 1.5t, hydraulic oil was let out in the oil drum through unloader valve, prevented the damage of towing machine wheel overload.Safety handle 361 is housed on the cavity 351, and when rack shaft 331 moves to assigned position, safety handle 361 will be moved down certainly and inserted in the hole on the rack shaft 331, move behind the rack shaft 331 that prevents to cause because of hydraulic pressure is malfunctioning.Breather stem vent plug 371 is housed on the cavity 351, can bleeds off the air in the oil drum 381 when unscrewing breather stem vent plug 371; When using towing machine wheel, should unscrew breather stem vent plug 371, make oil drum 381 and atmosphere, with after should close breather stem vent plug 371, prevent in rainwater, the foreign material entering oil drum 381.On the oil drum 381 oil filler plug is housed, takes out oil filler plug and can in towing machine wheel, inject No. 15 aeronautic hydraulic oil.
The foregoing description, just the preferred embodiment of the utility model is not to be used for limiting the utility model practical range, so all equivalences of being done with the said content of the utility model claim change, all should be included within the utility model claim scope.
