Description
技术领域： Technical field:
本发明涉及工具领域，具体地说是一种更换输电线路中合成绝缘子的钳型带电作业卡具及使用方法。The invention relates to the field of tools, in particular to a pincer-type live work jig for replacing synthetic insulators in power transmission lines and a method for using it.
背景技术： Background technique:
众所周知，绝缘子是输电线路中的易损件，更换绝缘子时一般使用直线卡具，直线卡具由设有U型槽和丝杠孔的卡具体、带定位块的丝杠和丝杠扳手组成，卡具体上卡槽一侧设有紧固螺丝柄，丝杠孔可以设置有与丝杠相啮合的螺纹，也可以在卡具体上设置与丝杠相啮合卡槽和导柱，这种卡具只能适用于直线水泥杆及单回直线塔，应用于水泥杆时卡具安装在绝缘子挂点上方角铁上，由于铁塔的横担绝缘子挂点处角铁的长度比水泥杆的短1/3左右，所以铁塔上使用的直线卡具只能安装在横担两边的角铁上使用，由于角铁长短和规格存在差异，横担两边角铁的承力系数明显降低，这样一来，卡具不能在双回路塔、下压较大塔和大跨越档距塔等特殊直线塔使用，另外，这种卡具卡在横担两边的角铁上使用会使卡具与导线的竖直方向存在一定的夹角，卡具U型槽的开口方向恰好与导线相同，使得卡具的丝杠不能沿导线垂直方向摆动，限制了丝杠和卡具的可操作性，由于U型槽和丝杠间只存在1-2mm间隙，按照目前所有类型直线铁塔横担结构情况，当卡具丝杠倾角大于5°时，丝杠和卡具会存在死角出现卡死现象，丝杠单边受力过大，操作十分困难，而且存在很不安全因素。As we all know, insulators are wearing parts in power transmission lines. When replacing insulators, linear clamps are generally used. The linear clamps are composed of a clamp body with a U-shaped groove and a screw hole, a screw with a positioning block and a screw wrench. There is a fastening screw handle on one side of the card slot on the clamp body, and the screw hole can be provided with a thread that meshes with the lead screw, or a card slot and a guide post that engage with the screw screw can be provided on the clamp body. It can only be applied to straight cement poles and single-circuit straight towers. When applied to cement poles, the fixture is installed on the angle iron above the insulator hanging point, because the length of the angle iron at the cross arm insulator hanging point of the iron tower is 1/2 shorter than that of the cement pole. 3 or so, so the straight line clamps used on the iron tower can only be installed on the angle irons on both sides of the cross arm. Due to the differences in the length and specifications of the angle irons, the bearing coefficient of the angle irons on both sides of the cross arm is significantly reduced. The fixture cannot be used on special straight-line towers such as double-circuit towers, large down-pressure towers, and long-span span towers. In addition, the use of this fixture on the angle irons on both sides of the cross arm will cause the vertical direction of the fixture and the wire to exist. At a certain angle, the opening direction of the U-shaped groove of the fixture is exactly the same as the wire, so that the lead screw of the fixture cannot swing along the vertical direction of the wire, which limits the operability of the lead screw and the fixture. Due to the U-shaped groove and the lead screw There is only a 1-2mm gap between them. According to the current structure of all types of straight iron tower crossarms, when the inclination angle of the lead screw of the fixture is greater than 5°, there will be dead angles between the lead screw and the fixture, and the lead screw will be stuck. Large, very difficult to operate, and there are very unsafe factors.
