Embodiment Construction

[0031] A gripping tool for indirect electrification work according to an embodiment of the present invention will be described based on the drawings. Hereinafter, the axial direction of the insulating operating rod 14 is defined as an up-down direction, and a direction away from the central axis of the insulating operating rod 14 is defined as outward. In addition, embodiment shown below is an example which actualized this invention, and does not limit the technical scope of this invention.

[0032] figure 1 The holding tool 10 for indirect electrified work shown in has: a holding part 12 for holding an object 84 to hold; an insulating operating rod 14 with the holding part 12 installed at the front end; an auxiliary insulating operating rod 24 for holding the operating part 26 The operation is transmitted to the grip portion 12; the grip operation portion 26 is provided near the base end portion of the insulating operating lever 14; and the pivot 30. The grip operation part...

Abstract

The present invention provides a holding tool for indirect electrification work that can reliably hold a linear object, a plate-shaped object, or a cloth-shaped object with a diameter or thickness of 2 mm to 5 mm without damage. The holding tool (10) for indirect electrified work is characterized by having an insulating operating rod (14), a holding portion (12) having a movable holding portion (20) and a fixed holding portion (22), and an auxiliary insulating operating rod (24). , holding the operating part (26) and the pivot (30), the fixed holding part (22) and the movable holding part (20) have a base part (22d, 20d), an arm part (22b, 20b) and an abutment part (22a, 20a), the abutment portion (22a) and the abutment portion (20a) are all provided with a plurality of protrusions (W), the abutment portion (22a) of the fixed grip portion (22) and the abutment of the movable grip portion (20) The connecting portion (20a) is configured to hold the electric wire (84) at a distance equal to or close to the diameter of the electric wire (84) to be held when the electric wire (84) is held.

Description

technical field [0001] The present invention relates to a holding tool for indirect electrification work. In particular, it relates to a holding tool for indirect live work capable of indirectly carrying out live work on a high-voltage power distribution line in a non-power failure state, and capable of holding the electric wire or the like. Background technique [0002] In the past, there are two types of live work for high-voltage distribution lines in power distribution projects without power failure: the direct live construction method and the indirect live live construction method. The direct electrification construction method is a construction method in which workers wear protective gear such as high-voltage rubber gloves and directly contact the high-voltage distribution lines that are energized to carry out power distribution work. However, there is a risk of electric shock accidents for workers. In contrast, the indirect live construction method is a construction ...
