活線作業用配電線支持装置を得ることを目的とする。Since the conventional distribution line support device for live line work is configured as described above, temporary support method type 1 is used to support the power line during power transmission.
Work on live power distribution lines cannot be done without deploying a pair of 2 and an aerial work vehicle 2 for carrying workers, which increases costs and requires a large on-street parking space. There was a problem. In addition, when cutting electric wires (main lines) that are currently transmitting power due to changes in pole installation, etc., we also need to install wire tensioners to temporarily hold and adjust the tension of the wires to be cut, as well as carry out tensioning operations to prevent power outages. From this point of view, worker M has to install all the bypass circuits (bypass cables) to connect the cut wires during power transmission, which is very inefficient and poses a risk of electric shock, etc. There was a problem with this. This invention was made in order to solve the above-mentioned problems, and it is an activity that allows work on distribution lines such as changing pole installation while the lines are live to be carried out safely and efficiently using a single aerial work vehicle. The purpose is to obtain a distribution line support device for line work.

Duplicate explanations will be omitted. In the figure, reference numeral 13 denotes a support arm for attaching to a utility pole, which is detachably attached to the utility pole IO as a main body of the distribution line support device 4 and held parallel to the utility pole arm 11, and 30 indicates this support arm. - A utility pole gripping mechanism is provided on the arm 13 and grips the utility pole 10 to support and fix the support arm 13 to the utility pole IO. The utility pole gripping mechanism 30 is configured to automatically and mechanically open and close the utility pole 10 by an external control signal such as a remote control. Reference numeral 60 denotes a plurality of wire pulling arms arranged and held in orthogonal directions on the support arm 13 and arranged in rows at the same intervals as the wires 8. The wire pulling arm 60 has a hollow fixed arm 61 fixed to the support arm 13, and a pair of left and right movable arms 62 fitted inside both sides of the fixed arm 61 so as to be extendable and slidable. It has become. Reference numeral 63 is a wire tensioning hydraulic cylinder (63) housed within the fixed arm 61 as shown in FIG. 64 is a hydraulic cylinder 6 for tensioning the wire.
3. This is the mounting fixture. Reference numeral 50 denotes an elevating drive section of the wire gripping mechanism 6, which includes a cylinder box section 51 connected to the outer ends of both movable arms 62, and an elevating drive section housed within the cylinder box section 51, as shown in FIG. The piston rod 52a of the lifting cylinder 52 is composed of a driving cylinder 52.
It protrudes upward from the cylinder box part 51 and integrally supports the electric wire gripping mechanism 6. Reference numeral 41 designates a base of the wire gripping mechanism 6, which is approximately U-shaped and whose bottom portion is connected and supported by the upper end of the piston rod F'52a. 42 is a movable wire gripping piece movably arranged on the base 41 and presses and grips the electric wire 8 with a bypass cable connector 71 to be described later; 43 is a movable wire gripping piece 43 that connects and supports the wire gripping movable piece 42; This is a hydraulic cylinder that expands and contracts in the direction toward and away from the bypass cable connector 71, and is attached to one side wall of the base 41. Reference numeral 70 denotes a bypass cable for supplying current between the cutting of the electric wire 8 while it is being energized, and is inserted into the electric wire pulling arm 60 and led out to the base 41 of the electric wire gripping mechanism 6 at both ends of the electric wire pulling arm 60. ing. A bypass cable connector 71 is attached to the inner surface of the other side wall of the base 41 and faces the wire gripping movable piece 42.

Therefore, the electric wire gripping movable piece 42 and the bypass cable connector 71 constitute an electric wire clamper that clamps the electric wire 8 in an energized state during power transmission. 72 is housed within the fixed arm 61 to which the bypass cable 70 is connected.
This is a switch for switching on and off the electricity. 80 is a hydraulic drive control unit attached to the support arm 13, as shown in FIG. 82 is a winch attached to the telescopic boom 3B of the aerial work vehicle 2 as shown in FIG. 2, and 83 is a suspension rope with a hanging device for this winch 82. Next, the operation will be explained. When performing distribution line work such as changing the pole installation while the line is live, first use the winch 82 of the aerial work vehicle 2, and use the winch 82 to move the distribution line support device 4 to the working position at a predetermined height on the utility pole 10. lift up to. Then, in this lifting position, the utility pole gripping mechanism 30 grasps the utility pole 10, thereby supporting and fixing the distribution line support device 4 to the utility pole 10. Thereafter, the hanging rope 83 of the winch 82 is removed from the distribution line support device 4. Next, by extending the lifting cylinder 52, the wire gripping mechanism 6 is raised to a predetermined height position at which the wire gripping mechanism 6 can grip the wire 8. As a result, when the electric wire gripping mechanism 6 reaches a predetermined height position, it is stopped at that position, and then the electric wire gripping hydraulic cylinder 43 is extended. Then, the electric wire gripping movable piece 42 moves closer to the bypass cable connector 71, and finally the electric wire gripping movable piece 42 strips the sheath of the electric wire 8 that is transmitting power between it and the bypass cable connector 7I. (bare wire part). By gripping it, the electric wire 8 that is transmitting power comes into electrical contact with the bypass cable connector 71, and the bypass cable 70 becomes energized. Next, the wire tensioning arm 60 is expanded and contracted by activation of the wire tensioning hydraulic cylinder 63 to extend and retract the wire tensioning arm 60.

The electric wire 8 is held at a position near where a safe insulation distance can be obtained. In this state, the worker M above the above-mentioned worker M performs work on the distribution line, such as cutting the electric wire 8 between the bypass cable connectors 71, while the line is live. Even if the electric wire 8 is cut between the bypass cable connectors 71 in this way, if the switch 72 is turned on at the time of the cut, current will flow through the bypass cable 70 as described above, so it is possible to work on the distribution line without causing a power outage. can be carried out safely and smoothly. Furthermore, since the cylinder box portion 51, fixed arm 61, and movable arm 62 of the wire tensioning arm 60 are made of an insulator or are insulated, there is no risk of electric shock even if the worker M approaches them. In the above embodiment, a horizontal pole installation was explained, but it is also possible to install a vertical pole by changing the mounting method to the utility pole 10 and the direction of the lifting cylinder 52, and the distribution line work is performed by a robot instead of the worker M. You can go there. Also, telephone pole 1
The distribution line support device 4 is not necessarily attached to the winch 82, but may be performed by separately providing a dedicated arm or the like. Further, the extension/retraction driving means of the wire pulling arm 60 and the driving means of the wire gripping mechanism 6 are not limited to a hydraulic cylinder, but may be a hydraulic motor or other driving device, and in either case, the same as in the above embodiment. It has the effect of
