Description
Technical Field
The utility model relates to the technical field of electrified railway contact net parts, in particular to a dropper line of an electrified railway contact net.
Background
In electrified railway contact network equipment, the chord line is generally used for meeting the requirement of bearing capacity in chain-shaped suspension, and current smoothly passes through when needed. Through retrieving a reinforced type dropper wire disclosed in chinese patent publication No. CN216184639U, the problem that the dropper wire cannot be stably connected with the dropper wire clamp is raised, and the magnetic pole rod is led to extend out to limit with the dropper wire clamp by pushing the extrusion block to drive the magnetic pole block, so that the dropper wire clamp is conveniently clamped with the connecting block, and the effect of connecting stability is realized. However, since the pole is magnetically extended from the connection block and connected to the string clip, the pole ends are not in contact with the object, resulting in insufficient connection stability.
Disclosure of Invention
Aiming at the problems, the utility model provides a dropper wire of an electrified railway contact net, which solves the problem of insufficient connection stability between the dropper wire and a dropper wire clamp.
The technical scheme is as follows: the utility model provides a dropper wire of electrified railway contact net, its includes connecting device, connecting device is including the connecting block that is used for inserting the dropper fastener, be used for spacing with the dropper wire fastener and can follow the stopper that stretches out in the connecting block, its characterized in that: the limiting block is characterized in that the limiting block end part positioned in the connecting block is in sliding contact with the extruding block, the extruding block is in a conical shape with a small upper part and a big lower part, the connecting rod I is hinged to two sides of the lower end of the extruding block, the connecting rod II is hinged to the other end of the connecting rod I, the other end of the connecting rod II is hinged to a stop block in the connecting block, the connecting rod I and the connecting rod II are obliquely arranged and extend out of the connecting block through an avoidance hole formed in the side part of the connecting block, a spring is connected to the joint of the connecting rod I and the connecting rod II, and the other end of the spring abuts against the stop block.
It is further characterized by:
the connecting block is cylindrical, and the outer surface of the lower part of the connecting block is provided with threads and is connected with an adjusting ring through the threads.
After the structure is adopted, when the connecting block is inserted into the dropper wire clamp, the first connecting rod and the second connecting rod are extruded to push the extrusion block to move upwards, and the limiting block can be outwards ejected out due to the fact that the extrusion block is small in upper part and large in lower part, so that the limiting block and the dropper wire clamp are used for limiting, and the limiting rod is stretched out through the extrusion block, the end part of the limiting rod is in contact with the extrusion block, and the limiting rod is difficult to retract as long as the extrusion block does not retract, so that the connection stability is effectively guaranteed.
