Description
Technical field
The utility model relates to a kind of anchor fitting, particularly about the device of stage clip in a kind of fixedly locomotive traction energy disperser.
Background technology
The locomotive traction shock absorber is as the vitals of locomotive traction, and the requirement when assembling is relatively stricter.As shown in Figure 1, the coupler draft gear 1 in the existing locomotive traction shock absorber is installed in the coupler yoke 2, and stage clip in the coupler draft gear 13 connects a slave plate 4, and correspondence is provided with a pair of draft key hole 5 on side top frame of coupler yoke 2 and underframe.Before locomotive that coupler yoke 2 is packed into, since uncertain with stage clip 3 bonded assembly slave plates 4 positions, therefore hitch can only be connected on the coupler yoke 2, again coupler yoke 2 is put into locomotive.But to assembling, often there are a lot of inconvenience in the transposing of inter process, and overall package is cumbersome from stage clip 3.
Summary of the invention
At the problems referred to above, the purpose of this utility model provide a kind of can be at transposing fixing device of stage clip in locomotive traction energy disperser during operation.
For achieving the above object, the utility model is taked following technical scheme: the anchor fitting of stage clip in a kind of locomotive traction energy disperser, it is characterized in that: it comprises a screw rod and one and the nut that is used of described screw rod, described screw rod one end has a spiral shell head of being convenient to turn, the other end is used for pushing up the slave plate of establishing the locomotive traction shock absorber, the upper/lower terminal of described nut have with the locomotive traction shock absorber in pintle pin-and-hole two extension arms that are used that one is long and the other is short; The global shape of two described extension arms is cuboid.
Nut towards the first side of described spiral shell is arc-shaped surface.
The short-and-medium first side end of the described dorsad spiral shell of extension arm of described two extension arms has the circular arc chamfering.
The extension arm of described weak point is arranged on the upper end of described nut, and the extension arm of described length is arranged on the lower end of described nut.
The extension arm of described length is arranged on the upper end of described nut, and the extension arm of described weak point is arranged on the lower end of described nut.
The radial section shape of described spiral shell head is one of square and hexagon.
The utility model is owing to take above technical scheme, and it has the following advantages: 1, the utility model adopts fixedly slave plate of moving screw, has guaranteed the size of locomotive traction shock absorber stage clip when the transposing operation.2, nut of the present utility model can be extracted out from the pintle pin-and-hole of coupler yoke, therefore makes the carrying when the transposing operation of locomotive traction shock absorber more convenient.3, the utility model is simple in structure, convenient disassembly, and can recycle.4, the utility model can be for multiple energy disperser fixed measure, and is applied widely.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
As Fig. 2, shown in Figure 3, the utility model comprises a screw rod 6 and one and the nut 7 that is used of screw rod 6.Screw rod 6 one ends have a spiral shell head 61 of being convenient to turn, and the other end is used for pushing up the slave plate 4 of establishing the locomotive traction shock absorber.The upper/lower terminal of nut 7 has a short extension arm 71 and a long extension arm 72 respectively, and the global shape of short extension arm 71 and long extension arm 72 is cuboid,
And all has arc-shaped surface 73 towards spiral shell head 61 1 sides.Short extension arm 71 spiral shell head 61 1 side ends dorsad has circular arc chamfering 74.
In the foregoing description, the radial section shape of spiral shell head 61 can be that square also can be a hexagon.
In the foregoing description, short extension arm 71 can be arranged on the upper end of nut 7, also can be arranged on its lower end, and long stretching wall 72 is positioned at the upper end.
As shown in Figure 4, the utility model carries out using when stage clip is operated at the traction shock absorber of press-loading device to locomotive, the draft key hole 5 that the short extension arm 71 and the long extension arm 72 of nut 7 of the present utility model placed coupler yoke 2 respectively at first, its short-and-medium extension arm 71 is arranged in the draft key hole 5 of upper end, long extension arm 71 is arranged in the draft key hole 5 of lower end, then screw rod 6 is screwed into nut 7.When coupler draft gear 1 reaches the stage clip size, turn the spiral shell head 61 on the screw rod 6, make the other end of screw rod 6 hold out against on slave plate 4, make slave plate 4 and coupler draft gear 1 no longer mobile, guaranteed that thus the traction shock absorber carries out operation its stage clip size of when transposing and remains unchanged.
After the transposing operation finishes, to draw shock absorber puts in the locomotive, slave plate 4 is fixed by the machine coupler pocket in the locomotive with the position of coupler draft gear 1, then by turning the spiral shell head 61 in the screw rod 6, screw rod 6 and slave plate 4 are broken away from, because this moment, nut 7 of the present utility model no longer was subjected to the pressure effect of rut energy disperser 1, just can be with its from bottom to top extraction from the pintle pin-and-hole 5 of coupler yoke 2.The utility model can be taken out from the traction shock absorber thus, can then be utilized the utility model that the stage clip in another locomotive traction energy disperser 1 is fixed then.
The foregoing description only is a kind of better embodiment of the present utility model; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model; to improvement and the equivalents that individual component is carried out, should not get rid of outside protection domain of the present utility model.
