The technical scheme that the utility model provides is, a kind of rail vehicle hitch, comprise: hitch, mounting cylinder, leading screw, nut and slide block, the sidewall of described mounting cylinder offers bar hole, described leading screw and described mounting cylinder coaxially arrange and are rotatingly arranged in described mounting cylinder, described nut thread is connected on described leading screw, described slide block offers through hole, described skid to be connected in described mounting cylinder and to be connected with described nut, described leading screw is inserted in described through hole, described slide block is also provided with mount pad, described mount pad is connected with described hitch through described bar hole.
Further, the upper end of described mounting cylinder is provided with deep groove ball bearing, and the bottom of described mounting cylinder is provided with thrust ball bearing, and the top of described leading screw is inserted in described deep groove ball bearing, and the bottom of described leading screw is inserted in described thrust ball bearing.
Further, described slide block is resisted against the top of described nut.
Further, described slide block entirety is in tube-in-tube structure, and the inside of described tube-in-tube structure is provided with baffle plate, and described baffle plate offers described through hole, and described nut is arranged in described tube-in-tube structure.
The utility model also provides a kind of autorail, comprises car body, also comprises above-mentioned rail vehicle hitch, and the mounting cylinder of described rail vehicle hitch is fixed on described car body.
The rail vehicle hitch that the utility model provides and autorail, realize driving slide block to move up and down by adopting leading screw and nut screw connection, thus the hitch height be arranged on slide block can be adjusted easily, to meet the requirement of towing vehicle on railway and highway, when not dismantling hitch, realize regulating hitch height continuously, effectively raise the field of application of rail-road car, realize the commonality that improve rail vehicle hitch, and reduce the adjustment difficulty of rail vehicle hitch, easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the cutaway view of the utility model rail vehicle hitch embodiment.
Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the present embodiment rail vehicle hitch, comprise: hitch (not shown), mounting cylinder 1, leading screw 2, nut 3 and slide block 4, the sidewall of described mounting cylinder 1 offers bar hole 11, described leading screw 2 and described mounting cylinder 1 be coaxial to be arranged and is rotatingly arranged in described mounting cylinder 1, described nut 3 is threaded on described leading screw 2, described slide block 4 offers through hole 41, described slide block 4 to be slidably connected in described mounting cylinder 1 and to be connected with described nut 3, described leading screw 2 is inserted in described through hole 41, described slide block 4 is also provided with mount pad 5, described mount pad 5 is connected with described hitch through described bar hole 11.
Specifically, mounting cylinder in the present embodiment rail vehicle hitch is for being fixed on the car body of rail-road car, in use, according to the traction position requirement for height being pulled car, by rotational lead screw 2, nut 3 is made to move up and down to be with movable slider 4 to move up and down in mounting cylinder 1, the height and position that just can be adjusted to by slide block 4.Wherein, can rotate smoothly in order to ensure leading screw 2, the upper end of mounting cylinder 1 is provided with deep groove ball bearing 61, the bottom of described mounting cylinder 1 is provided with thrust ball bearing 62, the top of described leading screw 2 is inserted in described deep groove ball bearing 61, and the bottom of described leading screw 2 is inserted in described thrust ball bearing 62.
Further, in order to avoid hitch is in distraction procedure, power is delivered on nut 3 and leading screw 2, slide block 4 is resisted against the top of described nut 3, slide block 4 and nut 3 are only contact and be not fixed together, and when adjusting height, nut 3 rises and to be risen by band movable slider 4, and nut 3 declines, then slide block 4 declines automatically by gravity, after hitch is stressed, is delivered on mounting cylinder 1 by slide block 4 by power, and guarantee that leading screw 2 and nut 3 do not stress, improve reliability.Preferably, slide block 4 entirety is in tube-in-tube structure, and the inside of described tube-in-tube structure is provided with baffle plate 42, and described baffle plate 42 offers described through hole 41, and described nut 3 is arranged in described tube-in-tube structure.Concrete; by slide block 4 is designed to tube-in-tube structure; the area of contact between slide block 4 and mounting cylinder 1 can be increased; and nut 3 is arranged in tube-in-tube structure; can be protected nut 3 by tube-in-tube structure; more effectively avoid that hitch is stressed passes to nut 3, nut 3 provides raising force by contacting with the baffle plate 42 in tube-in-tube structure to slide block 4.
