Problems solved by technology

Therefore, it is required to design the insulating hanger with a relatively simple structure into a structure with better workability. If only the above-mentioned structure of the insulating hanger is used, the workability is not sufficient, and further improvement is required.

Embodiment Construction

[0018] Below, refer to Figure 1 to Figure 3 The tightening device 10 for the insulated overhead wire 20a of this embodiment will be described. In the drawings, the same reference numerals are assigned to the same components, and overlapping descriptions will be omitted. For convenience of description, the sizes and positional relationships of components shown in the drawings are sometimes exaggerated. In the following description, each element constituting the present embodiment may be constituted by a single component and serve as multiple elements, or the function of one component may be shared by multiple components.

[0019] Such as Figure 1 to Figure 3 As shown, the tightening device 10 for an insulated overhead wire 20 a according to this embodiment includes a base 1 , an insulating portion 2 , and a spring member 3 . The base 1 includes a first holding portion 1a. The base 1 holds the first end portion 21a of the first insulated overhead wire 21 by the first holdi...

Abstract

The invention provides a tightening device of insulated trolley wire capable of using a relatively simple structure to achieve higher workability and an insulated trolley using the tightening device. A tightening device comprises: a base portion; an insulator portion; and a spring member. The base portion has a first retaining portion. The base uses the first retaining portion to retain the first end portion of a first insulated trolley wire. The insulator portion has a second retaining portion. The insulator portion uses the second retaining portion to retain the second end portion of a second insulated trolley wire. The spring member applies an elastic force to the insulator portion such that the first retaining portion and the second retaining portion will become closer to each other. The tightening device further comprises: an adjusting portion for adjusting the magnitude of said elastic force. The base portion is configured to accommodate the insulator portion in such a way that it is movable along the direction of the aforementioned elastic force applied by the spring member.

Description

technical field [0001] The present invention relates to a tightening device capable of tightening insulating overhead wires and an insulating hanger using the tightening device. Background technique [0002] Conventionally, transportation machines have been used in various production sites and the like. Handling machinery moves load-bearing devices such as cranes or cranes by moving equipment. Insulating hangers are used as a mobile power supply system that supplies power to mobile equipment in transportation machines. The insulating hanger is capable of supplying power from the insulated overhead line to the mobile device via the current collector of the mobile device. [0003] As such an insulating hanger, there is known an insulating hanger that applies tension to the insulating overhead line using a connector that connects the insulating overhead line to the power line on the primary side (for example, refer to Document 1 [Japanese Laid-Open Patent Publication No. 2012...
