Description
Technical field:
The utility model relates to a kind of railway track circuit maintenance tool, and specifically a kind of plug pin pulls out head and plug pin extractor.
Background technology:
Bond wire, wire jumper, lead-in that railway track circuit is used are between rail and rail, rail and frog, rail and transformer tank, lean on the plug pin at two ends to be connected with rail, frog etc., are the important equipment that guarantees information reliable delivery in the circuit.In actual maintenance work, more frequent to the replacing of bond wire, wire jumper, lead-in.Because plug pin is to pour in the hole of mother metals such as rail, frog, constitutes saturated or interference fit, therefore when changing, extracting of plug pin is quite difficult, and also effective without comparison at present instrument is extracted plug pin.Existing way one is manually to prize by the nail nipping crowbar, wastes time and energy, and often is damaged, and is easy to cause the operating personnel to injure, and the reliability of extracting is not more than 70%; The 2nd, manually go out from the plug pin afterbody with drift, but because the plug pin material mostly is the steel less than No. 30, afterbody be hit the distortion bigger, easily form shoulder block, impact extraction efficiency and also be not more than 70%, the plug pin of locating at stock rail and tongue, frog etc. particularly, because of being subjected to structural limitations, at all can not be with impacting the way of taking out; The 3rd, adopt destroy method to remove, promptly allow plug pin be retained on the mother metal, change bond wire, wire jumper, lead-in in the way of perforating elsewhere, thereby cause on mother metal, forming new defective.
Summary of the invention:
The purpose of this utility model provides a kind of plug pin shifting block and plug pin extractor.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of plug pin pulls out head, described shifting block is a hollow cylinder, on the tube wall of hollow cylinder one end, be provided with and be convenient to the shaft orientation opening groove that plug pin is put into and taken out, end face inwall at hollow cylinder is provided with the load step corresponding with plug pin reducing step, is provided with axially directed groove at the outer wall of hollow cylinder.
The width of shaft orientation opening groove described in the utility model at load step place is the diameter less than the plug pin head, greater than the diameter of plug pin bottom.
A kind of plug pin extractor that adopts above-mentioned plug pin shifting block, described shifting block places in the dial sleeve, the also corresponding shaft orientation opening groove that is provided with on the dial sleeve, on the dial sleeve with the corresponding guider screw that is provided with of axially directed groove on the shifting block, the shifting block other end is inner screw sheath and connects with the screw rod of driving lever one end, end cap with pull out external threading and connect, be provided with hand crank at the other end of driving lever.
The utility model is pulling out the thrust ball bearing that is provided with between cover and the dead man with the resistance of reducing friction.
The utility model is provided with the square head that is used to use the wrench reinforcing at the other end of driving lever.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, operate, carry, easy to maintenance, maximum overall dimensions Φ 42mm*280mm, weight is applicable to extracting of the various plug pin of railway signal system less than 2.3kg, particularly the plug pin that frog, tongue and stock rail place are difficult to take out can both effectively be extracted.
