Abstract

The adjustment plate with its own back-up protection device belongs to the technical field of overhead transmission line connection hardware protection. The technical problem to be solved is to provide an adjustment plate that can quickly and safely adjust the sag. The technical solution adopted is: in the adjustment plate body There are fixed connection holes at the central corner end, and a plurality of adjustment connection holes are spaced apart in the middle of the adjustment plate body, and the plurality of adjustment connection holes are distributed in an arc shape; the first three-eye connecting plate body, the second three-eye connecting plate body The structure is: holes are opened at both ends, one end is the bolt hole for connecting the adjusting bolt, and the other end is the wire connecting hole for connecting the wire, the adjusting bolt passes through the bolt hole of the first three-eye connecting plate body and the adjusting connecting hole of the adjusting plate body in turn After the bolt holes of the second three-eye connecting plate body, the first three-eye connecting plate body and the second three-eye connecting plate body are respectively connected to both sides of the adjusting plate body. The present invention is applied to the protection of overhead transmission line connection fittings.

Description

technical field [0001] The utility model relates to an adjustment plate with a backup protection device, which belongs to the technical field of protection for overhead transmission line connection fittings. Background technique [0002] In the actual operation of transmission lines, due to long-term operation and environmental changes, the conductor sag (sag) often does not meet the design requirements, and sag adjustment is required. According to the regulations, "adjusting the sag requires tightening the conductor tension and It can only be carried out after taking backup protection measures.” However, the existing sag adjustment work consumes a lot of manpower and material resources, and the safety is not high, and there is a lack of tools that can quickly and safely adjust the sag. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an adjusting plate capable of quickly and safely adjusting sag. [0004] In or...
