Abstract
The utility model provides a tip rod which is used on a rail switch of a railway. The tip rod comprises a straight pull rod with a groove and a tip iron, and one end is provided with a spiral buckle joint which is connected with the tip iron. The utility model is characterized in that the position between the straight pull rod with the groove and the spiral buckle joint is provided with regulating nuts, two ends of which are respectively connected with the straight pull rod with the groove and the spiral buckle joint by screw threads. The width of a tip rail can be discretionally regulated without disassemble and blocking a running section of a train.
Description
The utility model relates to a kind of front rod of a point that is used on the railway switch.
Be used for the front rod of a point on the railway switch, its effect is to guarantee that the switch blade opening in the regulation gauge, guarantees to cause the trouble-free operation of train.Owing to the bump of train wheel rim, its width can change this front rod of a point after use a period of time.For guaranteeing train safe, must in time regulate.The front rod of a point that is used at present on the railway comprises the spiral shell snapping head that most advanced and sophisticated iron, an end are connected with most advanced and sophisticated iron by cottor pin and connecting pin, and spiral shell snapping head is connected with trough of belt Drag link internal thread.Regulating its length must extract the cottor pin that inserts on the connecting pin, and then connecting pin is pulled out from spiral shell snapping head and most advanced and sophisticated iron mouth, regulates the purpose that spiral shell snapping head can reach adjusting again.Must block train running interval during adjusting, could regulate after with the locking of tongue and stock rail with hook lock device, its adjustable range is inaccurate, and minimal adjustment is apart from being half pitch, could regulate after must extracting cottor pin and connecting pin in addition, and is very inconvenient.
In view of above reason, the purpose of this utility model is just can regulate not dismantling of tongue width arbitrarily and can regulate front rod of a point in order to overcome above shortcoming, to provide a kind of and need not block train running interval, need not dismantling.
The purpose of this utility model is achieved in that the utility model is the improvement on existing front rod of a point, the utility model front rod of a point comprises the spiral shell snapping head that trough of belt Drag link, most advanced and sophisticated iron, an end are connected with most advanced and sophisticated iron, the adjusting nut (referring to Fig. 1, Fig. 2) that it is characterized in that having between trough of belt Drag link and spiral shell snapping head two ends to be connected with spiral shell snapping head thread with the trough of belt Drag link respectively.
Above-mentioned adjusting nut two ends are respectively left hand thread, right-handed thread, and concave hole (referring to Fig. 1, Fig. 2) is arranged between left and right hand thread.
There is the locking nut (referring to Fig. 1, Fig. 2) that is connected on trough of belt Drag link and the spiral shell snapping head at the two ends of above-mentioned adjusting nut.
Referring to Fig. 1, Fig. 2, when needing to regulate the width of front rod of a point, only need to unclamp locking nut with spanner, pull adjusting nut and can regulate.
The utility model need not be dismantled part just can regulate the tongue width, without closing the section, all can regulate before and after train operation, and the tongue width can be regulated arbitrarily, and is easy to adjust.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
Referring to Fig. 1, Fig. 2, the upper and lower end of adjusting nut 1 is respectively a left side (instead) and revolves screw thread 2 and the right side (just) revolves screw thread 3, and its two sections screw thread transition positions are concave hole 4.The spiral shell snapping head 8 that is connected with most advanced and sophisticated iron 7 by cottor pin 5 and connecting pin 6 is threaded with the adjusting nut upper end, and the lower end of adjusting nut is threaded with trough of belt Drag link 9.Locking nut 10,11 is loaded on respectively on most advanced and sophisticated iron and the trough of belt Drag link.
Claims (3)
1, do not dismantle and to regulate front rod of a point, comprise the spiral shell snapping head that trough of belt Drag link, most advanced and sophisticated iron, an end are connected with most advanced and sophisticated iron, the adjusting nut that it is characterized in that having between trough of belt Drag link and spiral shell snapping head two ends to be connected with spiral shell snapping head thread with the trough of belt Drag link respectively.
2, according to claim 1 the dismounting can be regulated front rod of a point, it is characterized in that the adjusting nut two ends are respectively left hand thread and right-handed thread, have concave hole between left and right hand thread.
3, according to claim 1 and 2 the dismounting can be regulated front rod of a point, it is characterized in that there is the locking nut that is connected on trough of belt Drag link and the screw socket joint at the two ends of adjusting nut.
