Description
Technical field
The utility model relates to a kind of traction bindiny mechanism, particularly about a kind of traction bindiny mechanism that is applicable in the little space.
Background technology
Pull line is an a kind of emergent traction bindiny mechanism, and it is widely used in the traction work of various mechanicals device.Such as, because under some particular case, aircraft, automobile, steamer all need specific traction bindiny mechanism to draw to move to, at this moment, generally need pull line to realize.
In the real aircraft distraction procedure, pull line generally is connected on the main landing gear wheel shaft of aircraft.Wherein, the pull line joint is two fork ears, it is separately positioned on the monaural both sides on the main landing gear wheel shaft, and laterally runs through the pull line joint by one and realize connection tie bolt between the two for two fork ears and main landing gear wheel shaft monaural, thereby makes things convenient for the traction between the two.
Yet certain type aircraft is because the change of brake system, causes that distance diminishes between the two-wheeled, and when with the two ear modes of pitching of prior art pull line when connecting, the horizontal axial space between its ears is not enough, is difficult to install tie bolt.Therefore, the connection in the little space of prior art pull line two fork ear connection mode incompatibility.
And the emergent traction of aircraft axial load is big, and very big lateral loading is arranged, and can not use bearing pin to connect, also be inconvenient to use be articulated and connected, otherwise, because load is excessive, there is potential safety hazard.Therefore be badly in need of a kind ofly satisfying big load little space in and safe and reliable aircraft draws bindiny mechanism.
The utility model content
Can't realize that in order to solve the prior art trailer coupling traction of big load aircraft in the little space connects, the utility model provides a kind of safe and reliable and bindiny mechanism can realize the traction of big load aircraft in little space.
In order to solve the problems of the technologies described above, the utility model provides following technical solution: a kind of traction bindiny mechanism, it is made up of the auricle that has little axle, first nut, fork ear, independent auricle, bolt, second nut.Wherein, described independent auricle is oppositely arranged with the auricle that has little axle, and independent auricle be provided with two respectively with the little axle and the corresponding screw of bolt of the auricle that has little axle, described screw bolt passes independence auricle, pitch ear, have the auricle of little axle, and it stretches out auricle one end that has little axle and is fastened by first nut back of the body, little axle in the described auricle that has a little axle passes successively and is pulled parts auricle, independent auricle, and is fixed by second nut.
The little shaft diameter of described auricle with little axle is less than the diameter of bolt, and the little axle of described auricle with little axle realizes and the captiveing joint of auricle that by welding wherein, the diameter of described bolt is 30mm.
In addition, described be arranged on the auricle and the fork ear between the independent auricle of little axle and be pulled between the parts auricle have the space.
Be different from prior art, fork ear of the present utility model realizes that with independent auricle the traction between the two is connected by the auricle with little axle respectively with being pulled the parts auricle and since the fork ear be pulled the parts auricle and be vertical arrangement, so lateral dimension is less.And be arranged on the fork ear be pulled the parts auricle with the transverse width of the auricle of little axle and independent auricle much smaller than fork ear width be pulled parts auricle width, therefore can significantly dwindle the space of traction bindiny mechanism, thereby be applicable to that traction connects in the little space.In addition, because the diameter of bolt of locking fork ear is pulled the little shaft diameter of parts auricle greater than locking, can bear big transverse load.Therefore the utility model traction bindiny mechanism can realize big load traction, the safe reliability height, and the big load aircraft traction that can satisfy in the small space connects.
Description of drawings
Fig. 1 is the structural representation of the utility model traction bindiny mechanism one better embodiment;
Wherein, the 1-auricle, 2-first nut, 3-fork ear, 4-independence auricle, 5-bolt, 6-second nut, the 7-that have a little axle is pulled the parts auricle.
The specific embodiment
See also Fig. 1, it is the structural representation of the utility model traction bindiny mechanism one better embodiment.The bindiny mechanism of drawing of the present utility model is made up of the auricle 1 that has little axle, first nut 2, fork ear 3, independent auricle 4, bolt 5 and second nut 6.Wherein, described independent auricle 4 is oppositely arranged with the auricle 1 that has little axle, and independent auricle 4 be provided with two respectively with the little axle and the bolt 5 corresponding screws of the auricle 1 that has little axle.Described bolt 5 passes independent auricle 4, fork ear 3 successively, has the auricle 1 of little axle, and it stretches out auricle 1 one ends that have little axle and is fastened by first nut, 2 back ofs the body.Little axle in the described auricle 1 that has a little axle and auricle 1 are for being welded to connect, and this little axle passes successively and is pulled parts auricle 7, independent auricle 4, and is fastened by second nut, 6 back ofs the body, wherein, in this embodiment, be pulled parts auricle 7 for being pulled the alighting gear auricle.
Described be arranged on the auricle 1 and the fork ear 3 between the independent auricle 4 of little axle and be pulled between the alighting gear auricle have the space, this fork ear 3 be pulled the alighting gear auricle by with the auricle 1 and independent auricle 4 realizations of little axle being connected between the two, and can be by the transmission that realizes power between the two with the auricle and the independent auricle of little axle, transmission such as tractive force, promptly by traction power pulling fork ear 3, drive with independent auricle 4 by auricle 1 again and be pulled the alighting gear auricle, thereby realize towage with little axle.And the diameter of described bolt is 30mm, greater than little shaft diameter, therefore when bolt 5 during by 2 lockings of first nut, can bear bigger transverse load, thereby guarantees independent auricle 4, have the reliable connection between the auricle 1 of little axle, improves the safe reliability of drawing.
The sequence of erection of the traction bindiny mechanism in the present embodiment is as follows: pass independent auricle 4, fork ear 3 by king bolt 5 earlier.Then, the little axle that has in the auricle 1 of little axle is put on monaural on the main landing gear wheel shaft.Then king bolt 5 joins with screw on the auricle 1 that has little axle, and at this moment, king bolt 5 need not pass completely through the auricle 1 that has little axle.Rotate king bolt 5 then, make king bolt 5 dock and tighten, give primary nut 6 and fastening on the little shaft lock that passes independent auricle 4 again with big nut 2.Thereby realize fork ear 3 and reliable connection that is pulled between the alighting gear fork ear.
The utility model traction bindiny mechanism is not limited to the traction that is applied to undercarriage, can be widely used in the traction of various mechanical equipments, particularly is applicable to the towage of the heavy mechanical equipment that the traction connection space is comparatively narrow and small.
Fork ear of the present utility model in sum be pulled the parts auricle by realizing that with independent auricle the traction between the two is connected by the auricle with little axle of little axle and locked with bolts, the two is vertical arrangement, but not laterally is arranged side by side.And be arranged on the fork ear be pulled the parts auricle with the transverse width of the auricle of little axle and independent auricle much smaller than fork ear width be pulled parts auricle width, therefore can significantly dwindle the space of traction bindiny mechanism, thereby be applicable to towage in the small space.In addition, because the diameter of bolt greater than little axle, can bear big load.Therefore, the utility model traction bindiny mechanism can realize big load traction, the safe reliability height, and the big load aircraft traction that can satisfy in the small space connects.
