Embodiment
Draw-gear of the present invention is applicable to complete automobile collision test, but application of the present invention is not limited to this, is also applicable to the field that other needs traction guiding.
Draw-gear of the present invention comprises driver element, track, cable and traction pilot unit.Preferably, cable is wirerope.
Please refer to Fig. 1 to Fig. 4, the traction pilot unit 100 of present pre-ferred embodiments comprises lid 10, framework 20, first angle sheave 30 and the second angle sheave 40.
Framework 20 comprises base plate 21, the first side wall 22 and the second sidewall 23.Framework 20 inside forms an accommodating cavity 24, and wherein base plate 21 is positioned at the bottom of accommodating cavity 24, and the first side wall 22 and the second sidewall 23 are positioned at the periphery of accommodating cavity 24, and lid 10 is for covering the top of accommodating cavity 24.Base plate 21 is provided with first fixed structure 25, second fixed sturcture 26 and mounting hole 212.First fixed structure 25 comprises round platform 252 and rotating shaft 254, and rotating shaft 254 extends out from the top of round platform 252, and round platform 252 can be fixed by screws on base plate 21.Second fixed sturcture 26 comprises pedestal 262, round platform 264 and rotating shaft 266, and round platform 264 is fixed on pedestal 262, and rotating shaft 266 extends out from the top of round platform 264, and pedestal 262 can be fixed by screws on base plate 21.The first side wall 22 has the first breach 222, second sidewall 23 and has the second breach 224 and the 3rd breach 226.
Cave inward in the middle of the middle perisporium being provided with axis hole 34, first angle sheave 30 coordinated with rotating shaft 254 of first angle sheave 30, form the accommodating annular groove 32 removing journey cable 60a.First angle sheave 30 is rotatably installed in the rotating shaft 254 of first fixed structure 25.
The perisporium centre that second angle sheave 40 is provided with axis hole 44, second angle sheave 40 coordinated with rotating shaft 266 caves inward, and forms the annular groove 42 of accommodating backhaul cable 60b.Second angle sheave 40 is rotatably installed in the rotating shaft 266 of the second fixed sturcture 26.The horizontal level of the second angle sheave 40 is higher than the first angle sheave 30, and the difference in height of the two determines according to going the distance up and down of journey and backhaul cable 60a, 60b in track.
Preferably, rope skipping preventing structure 27 is set on the side of each angle sheave 30,40, such as, some cylinders can be set in the edge near angle sheave 30,40.The material of these cylinders can be plastic cement, and cylinder is arranged on base plate 21 by stud.The distance at cylinder and angle sheave 30,40 edge is designed to, and when tractive wire is not strained, tractive wire can be avoided to cross pine and be separated with angle sheave, and when tractive wire tensioning, cylinder also can not rub with cable.
Preferably, in order to reduce friction force when angle sheave 30,40 rotates, an antifriction combination 50 is set between angle sheave 30,40 and rotating shaft 254,266 respectively.Antifriction combination 50 comprises Upper gasket 52, lower gasket 54 and screw 56.Lower gasket 54 is annular gasket, is enclosed within rotating shaft 254,266, is positioned at below angle sheave 30,40.Have through hole 522 in the middle of Upper gasket 52, Upper gasket 52 is placed on above angle sheave 30,40.Screw 56 is through being fixed in rotating shaft 254,266 after the through hole 522 of Upper gasket 52, angle sheave 30,40 is between Upper gasket 52 and lower gasket 54, thus can reduce friction when rotating, and Upper gasket 52 can also prevent angle sheave 30,40 from departing from rotating shaft 254,266.
When installing draw-gear, traction pilot unit 100 is fixed on ground by bolt through mounting hole 212, and the first breach 222 is facing to track, and the second sidewall 23 is facing to driver element.Referring to Fig. 3, backhaul cable 60b becomes journey cable 60a after walking around driver element successively after track, the first breach 222, second angle sheave 40, the 3rd breach 236, removes journey cable 60a successively through the second breach 234, first angle sheave 30, first breach 222 and track.Remove journey cable 60a and backhaul cable 60b in track for distribute up and down, therefore can reduce the width of track, reduce the cost of draw-gear.
Be appreciated that the pedestal 262 of the second fixed sturcture 26 can be removed, and the height of corresponding increase round platform 264.
Be appreciated that round platform 25,26 also can replace with the platform of other shape.
Be appreciated that the height of the first angle sheave 30 and the second angle sheave 40 can be exchanged, or 60a becomes backhaul cable, and 60b becomes journey cable.
In another embodiment, please refer to Fig. 5, backhaul cable 60a ' becomes journey cable 60b ' after walking around driver element successively after track, the first breach 222, first angle sheave 30, second breach 234, removes journey cable 60b ' successively through the 3rd breach 236, second angle sheave 40, first breach 222 and track.Remove journey cable 60b ' and backhaul cable 60a ' in track for distribute up and down, therefore can reduce the width of track, the cost of reduction draw-gear.
The above, only embodiments of the invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
