[Problem to be solved by the invention]

Since the conventional power distribution line support device is configured as described above, when performing wiring work, two vehicles, the temporary support method vehicle 1 for supporting the electric wire 8 and the aerial work vehicle 2 for performing the work, are used. In addition, if the main line is cut due to changing the pole installation, etc., the operator must separately install a wire tensioner to hold the wire and adjust the tension, and carry out the wire tensioning work. There were issues such as not being able to do so.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to obtain a power distribution line support device that can perform various wiring works with a single aerial work vehicle.

[Means to solve the problem]

A power distribution line support device according to the present invention includes a support arm provided with a wire gripping mechanism for gripping a wire, this support arm supported by an arm support mechanism, and further this arm support mechanism attached to the power distribution line support mechanism so as to be movable up and down. This power distribution line support mechanism is provided with a utility pole gripping mechanism to enable fixation to the utility pole, and the utility pole gripping mechanism and the arm support mechanism are operable by a drive mechanism using hydraulic pressure or the like.

[Effect]

After the distribution line support mechanism of the present invention is installed on a utility pole by the utility pole gripping mechanism, it is possible to grasp the electric wire, push up the electric wire while holding it, and maintain and inspect the electric wire without using an aerial work vehicle. During this period, the aerial work vehicle will be available for the pole installation work.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 3a is the telescopic pool of the aerial work vehicle 2 similar to that shown in FIG. 6, 4A is the distribution line support mechanism, 8 is the electric wire, 10 is the utility pole, 11 is the utility pole arm, and 12 is the telescopic pool. A packet is supported by 3a, 13 is a worker, and 30 is a utility pole gripping mechanism.

A vertical drive screw that moves up and down while rotating; 6 is a one-wire gripping mechanism provided on the support arm 5; 51 is a presser drive device that drives a wire valve holder 52 as shown in FIG. 3; and 52 is a wire supporter. This is the above electric wire valve fitting that prevents the electric wire 8 that has entered the inside of the electric wire 8 from coming off. 4 and 5 show a wire tensioning mechanism 60 provided in the support arm 5. In the same figure, 61 is a drum drive device that operates a pair of wire winding sitrams 63 for adjusting tension, and 62 is a drum drive device. A transmission device that connects the drive device 161 and the wire winding drum; 64 is a camler that grips the electric wire 8; 65 is a wire that connects the camler 64 and the wire winding drum 63; 80 is a drive for the distribution line support mechanism 4A shown in FIG. unit, which receives external hydraulic pressure to support the arm support mechanism 40. The operation of the utility pole gripping mechanism 30 is controlled. 81 is a hydraulic hose that supplies oil as a power source to the external power distribution line support mechanism 4A, 82 is a winch attached to the telescopic poom 3a, and 83 is a hanging tool.

Next, the operation will be explained.

A packet 12 is placed at the tip of the telescopic pool 3a of the aerial work vehicle 2.
is attached to the packet 12, and a winch 82 for hoisting the transformer etc. is attached to the packet 12.
Using the lifting tool 83 suspended from the winch 82, the distribution line support mechanism 4A is lifted at a predetermined position t-i on the utility pole 10. After lifting the distribution line support register 4A to a predetermined position, the utility pole gripping mechanism 30, which operates to open and close, is operated to close,
This power distribution line support 11114A is fixed to the utility pole 10.

Once the distribution line support 4A has been fixed to the utility pole 10, the packet 12 of the aerial work vehicle 2 can be moved freely (can be used for other work) by removing the hanging device 83. Become.

Next, oil is supplied to the hydraulic hose 81 and the drive unit 80
, thereby rotating the vertical drive screw 42,
The support arm 5 on the arm support mechanism 40 is raised to the position of the electric wire 8, and the electric wire gripping mechanism 6 holds the electric wire If8B.

This method of holding the electric wire 8 is such that when the electric wire 8 is inserted into the electric wire support 53, the electric wire 8 is held by the electric wire valve actuator shown in FIG. This prevents the electric wire 8 from coming off from inside the electric wire support 53 due to vibration, wind, etc.

Next, the electric wire 8 is pushed up and held by the arm support mechanism 40 until a safe insulation distance is obtained from the utility pole arm 11, which is the work position of the worker 130, and the intended distribution line work is carried out.

Furthermore, when cutting the electric wire 8, a camler 64 is attached to the electric wire 8, each cut end of the smeared wire 8 is held by the wire tensioning mechanism 60, and the wire is wound up by the drum drive device 61).
The drum 63 is operated and the wire 65 is wound up or pulled out on the drum 63.

After the tension of the electric wire 8 is adjusted remotely, the above-mentioned cut end is connected.

The drum drive device 61 and arm support mechanism 40 are driven by a drive unit 80 using hydraulic pressure supplied from the outside through a hydraulic hose 81.

In this way, the distribution line support mechanism is configured such that the wire tensioning mechanism 60 is provided within the support arm 5 on which the wire gripping mechanism 6 is installed, so that the wire tensioning mechanism 60 can be cut and
To easily and quickly hold an electric wire and adjust its tension in parallel with other wiring work.

In addition, in the above embodiment, horizontal pole mounting was explained, but it may be used for vertical pole mounting by changing the mounting method to the utility pole 10 and the direction of the vertical movement mechanism, or it may be a separate work that is performed by the operator. This can also be done using a robot.

Further, in the above embodiment, the winch 82 is used to attach the device to the utility pole 10, but a dedicated arm or the like may be separately provided.

〔Effect of the invention〕

As described above, according to the present invention, the distribution line support mechanism is fixed to the utility pole by the utility pole gripping mechanism, and the electric wire gripping mechanism is configured to be movable up and down with respect to the distribution line support mechanism. In addition to being able to perform various distribution line work such as inspecting, repairing, and connecting distribution lines inexpensively and easily using the machine, it also has the effect of reducing the amount of on-street parking space required for work vehicles.
