The utility model discloses single line operation of just can accomplishing the nail, has practiced thrift construction cost greatly.
Description
Technical Field
The utility model relates to an electricity affair track equipment connecting wire especially relates to a track connecting wire.
Background
In recent years, the railway construction of China develops rapidly, the development of track circuit equipment is also different day by day, the construction of high-speed rails requires high speed and high safety quality coefficient, the requirement on track circuit connecting lines is higher and higher, the traditional connecting line adopts multi-strand injection molding and other blocking lines consisting of steel wires and copper wires, the elasticity and bending strength of the connecting lines are high due to the thick line diameter and the high elasticity of the steel wires, the traditional connecting line and a plug nail adopt a right-angle connection mode, a hole for connecting a steel rail and the plug nail is a hole perpendicular to the rail waist plane of the steel rail, the longitudinal central axis of the plug nail and the central axis of the steel rail hole form a certain angle when the steel rail is nailed due to the strong elasticity of the wire and the narrow space of the position of the steel rail hole, one person often needs to adjust the angle of the plug nail by hands to greatly, and the other person needs to drive the plug nail into the hole, the single line operation of hardly accomplishing the nail, efficiency and outward appearance aesthetic feeling all can not satisfy the high-speed railway, the construction operation requirement of subway, bring very big inconvenience for a ray of construction, construction cost increases at double, receive constructor operation quality and the influence of wire rod traditional manufacturing process, the back is followed closely to the stopper, the connecting wire can lead to connecting wire bending deformation together with the extrusion that the rail bottom can be tight, there is harmful friction between the two, the vibrations of train can lead to moulding plastics the inside corrosion of intaking of layer damage messenger wire rod, the disconnected strand appears in the steel wire that causes to form the connecting wire, bring the hidden danger for driving safety.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: overcomes the defects of the prior art and provides the track connecting line which can be used for completing the nail line operation by a single person.
The utility model discloses the technical problem that will solve is:
a track connecting line comprises a steel-clad copper line and a plug head, wherein the connecting end of the steel-clad copper line and the plug head is bent to form an included angle of 50-65 degrees, the bent end of the steel-clad copper line is welded with the plug head, the other end of the plug head is connected with a steel rail hole perpendicular to the plane of a steel rail web, and an injection-molded protective layer is arranged on the circumference of the welding position of the steel-clad copper line and the plug head.
The bending angle of the ladle copper wire is 50 degrees.
The bending angle of the ladle copper wire is 60 degrees.
The bending angle of the ladle copper wire is 65 degrees.
The size and the shape of the protective layer are matched with those of the welding position of the steel-clad copper wire and the plug head, and the bending direction of the steel-clad copper wire is based on the connecting end of the plug head and the steel rail hole.
The utility model discloses an actively beneficial effect is:
1. the utility model discloses in bend into 50 ~ 65 contained angles with ladle copper line and stopper nail head link, can solve at the scene because the elasticity of wire rod can not bend greatly and cause the construction inconvenience, can also batch industrial with ladle copper line wire rod setting processing, single just can accomplish the nail line operation like this, practiced thrift construction cost greatly.
2. The utility model discloses well ladle copper line can not lead to connecting wire bending deformation with the extrusion that the rail bottom can not be tight, has certain clearance between the two, can not lead to moulding plastics the layer damage and then make the inside corrosion of intaking of wire rod because of the vibrations of train, can not cause the broken strand of steel wire appearance that constitutes the connecting wire yet, has guaranteed the safety of driving a vehicle.
Drawings
Fig. 1 is a schematic structural diagram of the track connecting line of the present invention.
Detailed Description
The invention will be further explained and explained with reference to the drawings and the embodiments:
referring to fig. 1: in the figure, 1-copper clad wire, 2-nail head and 3-protective layer.
Example (b): the utility model provides a track connecting wire, includes ladle copper line 1 and stopper pin fin 2, and ladle copper line 1 bends into 50 ~ 65 contained angles with stopper pin fin 2 link, and the end after ladle copper line 1 bends is in the same place with stopper pin fin 2 welding, and perpendicular to rail web planar rail hole is connected to the other end of stopper pin fin 2, and ladle copper line 1 and stopper pin fin 2 welding department circumference are provided with injection moulding's inoxidizing coating 3.
The bending angle of the ladle copper wire 1 is 50 degrees.
The bending angle of the ladle copper wire 1 is 60 degrees.
The bending angle of the ladle copper wire 1 is 65 degrees.
The size and the shape of the protective layer 3 are matched with the size and the shape of the welding position of the steel-covered copper wire 1 and the plug head 2, and the direction of bending of the steel-covered copper wire 1 is used for plugging the connecting end of the plug head 2 and the steel rail hole.
During the use, before 1 wire rod of ladle copper line and the welding of stopper nail head 2, do the setting processing of bending with 1 wire rod of ladle copper line and 2 links of stopper nail head earlier, prune the parallel and level with 1 wire rod end of ladle copper line afterwards and weld together with stopper nail head 2, then with stopper nail head 2 injection moulding can, the track connecting wire after the shaping is connected with the planar rail hole vertical connection of rail web.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still fall within the scope of the technical solution of the present invention.
