Problems solved by technology

In addition, when the dump truck that has entered the both sides of the excavator and completed the loading operation is driven out of the work area, it moves after turning back in the work area, but when the dump truck that has been loaded in the work is turning back, It is possible to step on the cables arranged between the travel paths of the dump truck
As a result, it becomes difficult for the dump truck to turn back, and it becomes difficult to enter the dump truck on both sides of the excavator.

Embodiment approach 1

[0032]

[0033] figure 1 It is a schematic diagram of an excavator as an example of a loading machine to which electric power is supplied via the relay vehicle according to the first embodiment. The excavator 1 shown in the figure is an electric power machine that drives various parts with electric power supplied from the outside. This excavator 1 has an upper revolving structure 2 and an undercarriage 10 , and the upper revolving structure 2 and the undercarriage 10 are connected by a swing circle 16 capable of relative rotation. Among them, a working machine 3 as a working device including an arm 4 , a boom 5 , and a bucket 6 is attached to the upper swing body 2 . In addition, the undercarriage 10 includes a pair of left and right crawler belts 11 and a pair of left and right travel motors 12 that drive the crawler belts 11 by electric drive. The excavator 1 can travel by driving the crawler belts 11 with the travel motor 12 as described above.

Embodiment approach 2

[0075] The relay trolley 90 according to the second embodiment has substantially the same structure as the relay trolley 30 according to the first embodiment, but is characterized in that the cable support rod 95 is provided so as to be able to expand and contract. The rest of the structure is the same as that of Embodiment 1, so its description is omitted, and the same reference numerals are used.

[0077] Image 6 It is a schematic diagram of the relay vehicle according to Embodiment 2. Figure 7 yes means Image 6 An explanatory diagram of the retracted state of the cable support rod shown. The relay trolley 90 according to the second embodiment, like the relay trolley 30 according to the first embodiment, has a trolley main body 31 on which a cable drum 34 holding a cable 70 is mounted. Furthermore, a traveling device 50 is connected. In addition, the trolley main body 31 is provided with a cable support rod 95 for supporting the cable 70. However, this cabl...

Abstract

A power support system to an electric work machine includes: a cable holding unit configured to hold a cable that transmits power; a cable support pole configured to support the cable held by the cable holding unit at a position higher than a height of a vehicle that travels on a track that intersects at a position where the cable is disposed; and a travel device connected to the cable holding unit and the cable support pole and configured to perform a traveling operation so as to be able to move the cable holding unit and the cable support pole.

Description

technical field [0001] The present invention relates to a cable relay trolley with a pole and an electric power supply system for supplying electric power to an electric working machine. Background technique [0002] In recent years, from the standpoint of fuel consumption reduction and environmental protection, among machine tools such as hydraulic excavators, there are electrically driven machines that are driven by electric power. For example, the electric machine tool described in Patent Document 1 can be supplied with power from the outside through a cable, and can be driven by the power supplied from the outside in this way to perform operations such as excavation in mines and quarrying sites. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Unexamined Patent Publication No. 2010-65445 [0006] Summary of the invention [0007] The problem to be solved by the invention [0008] Here, the work area such as the quarry site...
