Embodiment Construction
[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0015] The multi-functional maintenance tool of this embodiment is used as an auxiliary tool when using the card meter to measure the grounding resistance of the transmission line tower, and the specific usage method will be described later. Such as figure 1 As shown, the multifunctional overhaul tool of this embodiment includes a first tool 1 and a second tool 2; figure 1 and figure 2 First, the structure of the first tool 1 is described. The first tool 1 includes a first body 10, a first wrench 11 arranged at one end of the first body 10, and a wrench 11 arranged at the other end of the first body 10 and along the first body 10. Two first side wings 13 extending in the length direction, one end of the two first side wings 13 are respectively connected to two sides of the first bo...

The invention discloses a multifunctional overhaul tool which comprises a first tool and a second tool, and further comprises a rod part connected with a bolt hole in a line tower or flat iron, wherein each of the first tool and the second tool comprises a main body, a spanner arranged at one end of the main body and two side wings arranged at the other end of the main body; slide grooves and a rotary shaft traversing the slide grooves are arranged on the side wings respectively; fastening nuts are arranged at one or two ends of the rotary shaft; the rod part is rotationally connected with the side wings through the rotary shaft; one end of the rod part is a clamping end, and the other end of the rod part is an operating end; an open groove in the length direction of the rod part is formed in the clamping end; a clamping block is rotationally connected to the interior of the open groove and rotates in or out of the open groove during rotation; a soft copper line is detachably connected between the rotary shaft of the first tool and the rotary shaft of the second tool. The tool has the benefits that the tool can be used as not only an auxiliary tool during measurement of a ground resistor of the power transmission line tower by a card meter but also a spanner, and the tool is convenient to carry and operate.
Description
technical field [0001] The invention relates to a multifunctional maintenance tool, which can be used as an auxiliary tool when using a card meter to measure the grounding resistance of a transmission line tower, and can also be used as a wrench. Background technique [0002] The line towers used on the high-voltage transmission line need to be grounded. With the development of the power grid, in order to ensure the safe operation of the line and make the line have a better grounding effect, the grounding electrode of the line tower is changed from the original steel bar connection to the flat iron connection. , that is, the angle steel at the bottom of the line tower is connected to the earth through flat iron. [0003] In order to ensure the safety of power supply, before the thunderstorm season comes every year, the power supply department will measure the grounding resistance of the tower of the transmission line. [0004] There are two types of measuring tools availabl...
