The invention discloses an anti-wear fitting for an overhead ground wire of a transmission line, and belongs to the technical field of installation equipment for overhead ground wires of a transmission line. A connecting pin is welded to the outer middle part of the hull of the suspension line clamp, and the connecting pin is connected to the inner ring of the slewing bearing. The hull of the suspension line clamp is connected to the line lifting lug plate through the slewing bearing, and the line lifting lug plate is underneath There is a bearing mounting hole, and the bearing mounting hole is snap-fitted with the outer ring of the slewing bearing. It has a simple structure and a reasonable design. The suspension line clamp, the hull and the line lifting ear plate are connected through the slewing bearing, so that the suspension line clamp, the hull and the line lifting ear plate are connected. The line lug plates can rotate between each other. When they swing under the action of wind, the suspension line clamp hull and the line lifting lug plate swing together, reducing friction at the contact parts, thereby reducing equipment damage, ensuring safe and stable operation of the equipment, and improving power supply. reliability.
Description
Technical Field
The invention relates to an anti-abrasion hardware fitting for an overhead ground wire of a power transmission line, and belongs to the technical field of installation tools for overhead ground wires of power transmission lines.
Background
The suspension clamp is mainly used for connecting a ground wire, an optical cable and the like of a power transmission line on a linear tower, has the function of effectively bearing the installation load of a wire in a vertical span, prevents the ground wire from slipping off or separating from an insulator string when the line normally runs or breaks, and is an important component of a power transmission line structure.
However, because the distribution of the power transmission line is diversified, natural disasters bring great threat to power transmission equipment, the occurrence of equipment damage caused by high wind occurs, the existing suspension clamp lifting lug swings under the action of wind force with the connecting plate connected with the suspension clamp lifting lug, the load born by the contact part exceeds the damage load of the suspension clamp lifting lug due to long-time friction, the serious damage can cause the falling of the guide wire and the ground wire to cause tripping accidents, and therefore, how to reform the equipment fitting to reduce the damage caused by natural factors becomes a problem which needs to be solved urgently.
Disclosure of Invention
Aiming at the problems, the invention aims to provide the wear-resistant hardware fitting for the overhead ground wire of the power transmission line.
The invention relates to an anti-wear fitting for an overhead ground wire of a power transmission line, which comprises a suspension clamp hull, a connecting pin, a rotary bearing, an inner ring, an outer ring, a wire lifting lug plate and a bearing mounting hole, wherein the connecting pin is welded at the middle part of the outer side of the suspension clamp hull and is connected with the inner ring of the rotary bearing, the suspension clamp hull is connected with the wire lifting lug plate through the rotary bearing, the bearing mounting hole is formed below the wire lifting lug plate, and the bearing mounting hole is clamped with the outer ring of the rotary bearing.
Preferably, during installation, the outer ring of the rotary bearing is clamped and fixed with a bearing mounting hole below the wire lifting lug plate, then the inner ring of the rotary bearing is fixed with a connecting pin on the suspension clamp ship body, the suspension clamp ship body and the wire lifting lug plate can rotate through the rotary bearing, and when the suspension clamp ship body and the wire lifting lug plate swing under the action of wind force, the suspension clamp ship body and the wire lifting lug plate swing together.
The invention has the beneficial effects that: its simple structure, reasonable in design is connected through slewing bearing between suspension clamp hull and the lifting lug board for can rotate between suspension clamp hull and the lifting lug board, when its swing under the effect of wind power, suspension clamp hull swings together with lifting lug board, reduces the contact position friction, thereby alleviates equipment damage degree, guarantees equipment safe and stable operation, improves power supply reliability.
