In the prior art, be that rail is hammered in the plug pin hole of rail waist with the wiring plug pin, thereby realize being electrically connected.Traditional rail is spike with the wiring plug pin, and the one of which end has wiring hole, and the plug pin hole has been bored at the waist of rail track by elder generation during use, plug pin is pounded in this plug pin hole fixed again, and the wiring hole of its outer end is as the fixing point of lead.Not only speed of application is slow with the wiring plug pin for this traditional rail; And plug pin is disposable product, can't change after the damage, can not change thereby cause lead once to be fixed on the plug pin; If rail replacement then causes all circuit on it to change simultaneously, influenced conevying efficiency.In addition, loosening in order to prevent plug pin, the plug pin top is fixed by screw, yet the plug pin hole of plug pin and rail waist in use, because the change of antirust oiling and various stress conditions, it is of common occurrence that the loosening phenomenon with loose contact of plug pin takes place.
[summary of the invention]
The object of the invention is exactly will solve above-mentioned deficiency and a kind of ground signalling connected nail is provided; Not only simple in structure; Convenient installation, dismounting and replacing, and its self-locking is effective, can be because of the loosening dropout that cause; And can fully contact with rail, guaranteed the safety of railway system's operation.
For realizing that above-mentioned purpose designs a kind of ground signalling connected nail; Comprise spiral shell tail cone bar 1, expansion sleeve 2 and stop nut 3; Said spiral shell tail cone bar 1 comprises conical nose 4 and screw rod tail 5, and said conical nose 4 is a pyramidal structure, and said screw rod tail 5 is for having externally threaded cylinder; Said conical nose 4 is an integral structure with screw rod tail 5; Said conical nose 4 peripheries are arranged with expansion sleeve 2, and said screw rod tail 5 peripheries are equipped with stop nut 3, and said stop nut 3 is threaded with screw rod tail 5.
Said expansion sleeve 2 comprises expansion body 6 and expansion set end face 7, and the diameter of said expansion body 6 peripheries is suitable with the aperture of rail connection holes 8, and said expansion sleeve 2 is connected with stop nut 3 face contact types through expansion set end face 7.
Said expansion sleeve 2 inside have the bellmouth that matches with conical nose 4.
Said stop nut 3 adopts medium carbon steel to process.
The present invention compares with prior art, has following advantage:
1. anticorrosion, quick detachable, can repeatedly use, good manufacturability, cost is low;
2. can guarantee that the ground signalling connected nail fully contacts with rail, thereby make signal held
Continuous guarantee;
3. novel structure, simple, simple to operate has made things convenient for installation, dismounting and replacing, has improved operating efficiency, has reduced manual work;
4. self-locking effect is remarkable, can be because of the loosening dropout that causes, and it is reliable to guarantee that signal circuit connects, thereby guarantees the safety of railway system's operation;
5. do not receive weather effect, use safer.

[embodiment]
Further specify below below in conjunction with accompanying drawing the present invention being done:
Shown in accompanying drawing 1 to accompanying drawing 5, the present invention includes spiral shell tail cone bar 1, expansion sleeve 2 and stop nut 3, said spiral shell tail cone bar 1 comprises conical nose 4 and screw rod tail 5; Said conical nose 4 is a pyramidal structure; Said screw rod tail 5 is for having externally threaded cylinder, and said conical nose 4 is an integral structure with screw rod tail 5, and said conical nose 4 peripheries are arranged with expansion sleeve 2; Said screw rod tail 5 peripheries are equipped with stop nut 3, and said stop nut 3 is threaded with screw rod tail 5.Said expansion sleeve 2 comprises expansion body 6 and expansion set end face 7, and the diameter of said expansion body 6 peripheries is suitable with the aperture of rail connection holes 8, and said expansion sleeve 2 is connected with stop nut 3 face contact types through expansion set end face 7.Said expansion sleeve 2 inside have the bellmouth that matches with conical nose 4.Said stop nut 3 adopts medium carbon steel to process.
Shown in accompanying drawing 6, be operation principle sketch map of the present invention, its operation principle is:
1. the electric way of contact of ground signalling connected nail is crimping;
2. the constant pulling force that is provided by instrument puts on the spiral shell tail cone bar, makes it to move along direction of pull, and the full superficial expansion of expansion sleeve is also pressed on rail connection holes hole wall, thereby forms complete surperficial crimping;
3. constant owing to pulling force, so crimp force is constant, promptly contact resistance is a definite value;
4. the expansion set end face of binding post and expansion sleeve carries out crimping with stop nut.
