Embodiment Construction

[0018] The insulator replacement tool of the present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the insulator replacement tool includes a support rod 1, which is a rod-shaped part made of a steel pipe. In order to improve the bending resistance of the support rod 1, the cross-sectional shape of the support rod 1 can be set as a polygon. When the strut 1 has sufficient strength, even if it will not bend during use, the cross-sectional shape of the strut 1 can also be set as a circle, and one end of the strut 1 is provided with a fixing rod 2 for fixing the strut 1 , the fixed rod 2 is perpendicular to the pole 1, and the other end of the pole 1 is provided with an elbow 3, and the fixed rod 2 is a rod for setting the pole 1 on the cross arm 18, and the fixed The rod 2 is set perpendicular to the pole 1 to make it more convenient to fix the fixed rod 2. In...

Abstract

The invention relates to a power grid emergency repair tool, in particular to an insulator replacement tool. The insulator replacement tool provided by the present invention can conveniently set the pole on the cross arm of the expansion tower by setting the fixing pole, which improves the fixing efficiency and strength of the pole; by using a lever block and a rope to tighten the cable, The cable is easy to tighten and reduces the labor intensity of the operator; by setting the fixed line and the positioning line, the pole is fixed more firmly, which improves the safety performance in the process of insulator replacement; stable performance.

Description

technical field [0001] The invention relates to a power grid emergency repair tool, in particular to an insulator replacement tool. Background technique [0002] When the power grid is erecting cables, in order to ensure reliable insulation between the expansion tower and the cable, an insulator is installed between the cable and the expansion tower. The insulator needs to be replaced after long-term use or damage to ensure reliable insulation between the cable and the expansion tower. insulation. [0003] When replacing the insulator, the cable on the insulator is removed first, and then the insulator is replaced. Since the cable is relatively heavy, it is necessary to fix the cable on the cross arm of the expansion tower after the cable is removed. In the prior art , After the cable is removed from the insulator, use a pole set on the cross arm to fix the cable. This kind of fixing method has the disadvantages that the pole is not fixed firmly and the cable fixing operati...
