The utility model relates to a middle-phase cross-arm clamp, which is characterized in that: a middle-phase cross-arm clamp includes a clamp plate; its features are as follows: the two ends of the clamp plate are provided with a connection structure which is tightly connected with a plane clamp on the middle-phase cross-arm of the iron tower; the connection structure at both ends of the clamp plate is a groove matching the plane size of the cross-arm of the iron tower; and a tightening wire screw is arranged in the middle of the clamp plate; The bottom of the tightening lead screw is connected with an insulating pull rod, and the bottom end of the insulating pull rod is connected with a connecting plate hook; the product is simple in structure, convenient in operation and suitable for popularization; the installation and disassembly of the product are relatively convenient, thus reducing the workload of the installer. The installation of the utility model on the plane of the middle-phase cross-load can increase the distance between the screw rod and the middle-phase wire, thereby increasing the safety group of the operator. The clamp is installed on the upper plane of the middle phase cross-arm, and the workers on the tower can stand on the lower plane of the middle phase cross-arm and tighten the screw rod upright so as to reduce the labor intensity of the workers; the utility model provides favorable conditions for realizing the safe live operation.
【技术实现步骤摘要】
一种中相横担卡具
本技术涉及一种卡具,具体是一种输电线路作业的中相横担卡具。
技术介绍
带电更换220kV输电线路“V”型绝缘子串是输电线路的一个重点项目。目前带电更换220kV输电线路V型绝缘子串作业,需要组三滑轮、横担边卡和吊篮配合,使作业人员进入等电位进行绝缘子更换,由于铁塔窗口很紧凑,等电位作业人员难以有效把握安全距离,所以存在较大安全隐患。同时,V型绝缘子串承受较大张力,给作业人员带了极大的操作困难和劳动强度。目前缺少针对该项目的相应工器具,所以很难开展220kV输电线路“V”型绝缘子串更换作业。
