Description

Ground pole tie

technical field

The utility model relates to the technical field of power outage maintenance of an electrified railway catenary, in particular to a binding device for grounding poles.

Background technique

During the maintenance operation of electrified railway catenary, it is necessary to hang the grounding wire before starting the operation, and remove the grounding wire after the operation is completed before power transmission can be opened. Hanging and removing the grounding wire must be carried out with the help of insulating rods, and the human body cannot touch the grounding wire to prevent personal electric shock casualties.

The insulating poles used are generally three sections (each section is 1.8-2.0 meters long), and they are tied with ropes or directly wrapped with grounding wires on the insulating poles for easy carrying when storing or transporting. Before the operation, it is necessary to untwist the wound ground wire from the insulating rod and connect the insulating rod. After the operation, the insulating rod needs to be pulled down and the ground wire is wound on the insulating rod. Because the grounding wire is 11-13 meters long and the outer diameter is 9 millimeters (25 square millimeters), this method is time-consuming and laborious, which affects the effective time of the power outage operation and reduces the utilization rate of the skylight time of the railway power outage operation.

Utility model content

The purpose of the utility model is to provide a grounding pole tie with simple structure, reasonable design and convenient use in view of the defects and deficiencies of the prior art.

In order to achieve the above object, the technical solution adopted by the utility model is: it includes a clamp, a crimping buckle, a rubber pad, an insulating rod groove, a base, a winding shaft, a U-shaped buckle, and a screw; the two ends of the clamp are respectively provided with Crimping buckle and U-shaped buckle, the upper end of the U-shaped buckle is screwed with a screw, the upper and lower surfaces of the fixture are respectively provided with rubber pads, and the surface of the rubber pad is provided with insulating rod grooves; The spool is fixed on the base.

Preferably, the winding shaft has a semicircular structure, and the upper and lower ends are respectively welded to the clamp and the base.

Preferably, a handle is connected to one end of the clamp.

When the utility model is bundled, the two ends of the stacked insulating rods are clamped respectively, and the three insulating rods are placed in the insulating rod groove of the bundler, and the clamps are fastened; one bundler and two bundlers are installed. The distance is about 1.5 meters. The base steel plates on the binder are facing both ends of the insulating rod, and then the grounding wire is wound in the shape of "8" on the winding shafts of the two binders, and the remaining grounding wire is wound on one end of the insulating rod. The wire end is fixed on the wire clamp of the binding device, and the binding of the grounding wire is completed; during operation, only need to loosen the wire clamp that fixes the wire end first, and loosen the clamp of the binding device to connect the insulating rod.

After adopting the above-mentioned structure, the beneficial effects of the utility model are as follows: the ground wire rod binding device described in the utility model can effectively improve the efficiency of the maintenance operation of the electrified railway catenary, and solve the problem that the ground wire hangs and withdraws from the site for a long time. As for the impact on maintenance work, it is a light, flexible, easy-to-operate and practical tool, which has significant advantages in saving the number of skylights and reducing production costs. The utility model has the advantages of simple structure, reasonable setting and low production cost. Etc.
