Description

[Detailed description of the invention] (Industrial field of application) This invention mainly relates to a column-mounted bucket for high-altitude work, which is used for maintenance work at high places such as overhead power distribution lines, and other appropriate high-place work. .

(Prior art) Conventionally, buckets for working at heights used when working on live overhead power distribution lines are installed in automobiles.
A boom or arm with a bucket at the tip is protruded from a car, and the boom or arm is extended, retracted, and rotated to bring the bucket closer to an elevated work area, and work is performed from inside the bucket.

(Problem that the invention aims to solve) This conventional system uses a car to support bucket carts for working at high places, but because it is a car, it cannot be used in narrow spaces, and the places where it can be used are limited. There is. Furthermore, vehicles must be parked on the road for hours while working at heights, which takes up a lot of space and becomes a traffic hindrance, especially in areas with heavy traffic.

(Means for solving the problem) Therefore, in a conventional aerial work vehicle, a work platform, etc., which is a pole-mounted work base, is attached to the tip of the boom, and this is simply and firmly attached to an appropriate location on the pole, and the boom It is conceivable to separate the poles, move the car with the boom installed, and then remove the pole-mounted workbench again using the car with the boom after completing work at high places.

This idea takes this idea further by attaching a fixed part at the base of the extendable arm that supports the bucket for work at height to the outer periphery of the column, which is slightly above the height of a person or car. From this point, the arm is extended to the high place work area using appropriate power.

That is, this invention provides a horizontal arm base which is formed by pivotally supporting and connecting two members and is rotatable in the horizontal direction, and a horizontal arm which is extendable and retractable in the longitudinal direction from one end of the horizontal arm base. The other end of the arm base is provided with a fixing part that can be detachably attached to a pole body such as a telephone pole, and the tip of the horizontal arm is provided with a vertical arm that has a bucket at the upper end and is extendable and retractable in the vertical direction. The fixing part pivotally supports one end of each of the two gripping pieces each having an arcuate cross section, and the bent edges of the other ends can be fixed with bolts and nuts, and one of the gripping pieces is attached to the other end of the horizontal arm base. This is a fixed configuration.

(Function) When working at heights, the device of this invention is transported to the work site using a truck with a boom etc. on the loading platform. The fixing part is attached to a pillar near the site at a position slightly higher than the height of passersby and cars, and the car is returned. When attaching this device to the column, rotate one of the two gripping pieces of the fixed part, wrap it around the outer circumference of the column with the two gripping pieces, and align the bent ends of each tip. By bringing the edges together and fixing them with bolts and nuts, the column is held between the two gripping pieces. This fixes the device to the column. When actually working at heights, if the pole is a utility pole, the power source is taken from the low-voltage line of the utility pole, and the arm is extended and contracted using hydraulic pressure, etc. to bring the bucket closer to the work place and work is carried out. . After completing the work at height, the retsu car is brought back to the site at a time when there is less traffic, the device of this invention is removed from the column, and transported to a storage location.

(Example) An example of this invention will be described below with reference to the drawings.
1 to 3 show a first embodiment of this invention, in which one end of the horizontal arm base 1 is provided with two gripping pieces 2, 2, each having a substantially semicircular cross section, which are crowned on the outer periphery of a utility pole and which can be freely tightened. A utility pole clamping part 3 is provided, and the free end of each of these gripping pieces 2 has a bent abutting edge 2a. This horizontal arm base body 1 is divided into two parts, which are connected to each other so as to be horizontally rotatable by a vertical shaft 4 and fixed at an appropriate position. Further, a horizontal arm 5 that can freely protrude from the horizontal arm base 1 is provided at the other end of the horizontal arm base 1, and a cylindrical vertical arm base 6 is fitted into an annular portion 5a at the tip of the horizontal arm 5. There is. A telescopic vertical arm 7 projects from the upper surface of the vertical arm base 6, and a bucket bag 8 is provided at the upper end of the vertical arm 7. These horizontal rotations of the horizontal arm base 1 and the extension and contraction of the horizontal arms 5 and vertical arms 7 are performed by appropriate power such as hydraulic pressure or air pressure, and can be controlled within the bucket 8, and the bucket 8 can be horizontally adjusted. It is possible. Further, the bucket 8 is insulated and further grounded from the utility pole clamping part 3.

In the case of this embodiment, this device is transported by truck to the work site early in the morning when traffic is light, the two gripping pieces 2 of the utility pole clamping part 3 are opened, and these are attached to, for example, a nearby utility pole 9. Place the two gripping pieces 2 on the outer periphery at a height that does not interfere with the movement of passersby or vehicles.
A bolt is passed through the bolt hole of each bent butting edge 2a of 2, and the nut is tightened to firmly fix the utility pole clamping part 3 to the utility pole 9. As a result, this device is attached to the utility pole 9, and the retouch vehicle leaves the site and returns home. When actually working at high places during the daytime, the worker gets on the bucket cart 8, operates the bucket cart 8, rotates the horizontal arm base 1 in the appropriate direction, and extends and contracts the horizontal arm 5 and vertical arm 7 to increase the height. The bucket 8 is brought close to the side of the work area and stopped. This allows the worker to work. After completing this high-place work, each arm is retracted, but the device remains attached to the utility pole, and later a retoucher truck comes to the work site and removes it from the utility pole 9.

Furthermore, the device of this invention is not limited to being attached to utility poles, but can be attached to any appropriate pole body. Therefore, when working at a height in a place where a car can enter and where conventional traffic is not frequent, the device of this invention should be attached in advance to a column 9' provided on the cargo bed of a car 18, as shown in Fig. 4. It is also possible to go to the work site with the vehicle 18 in place, stop the vehicle 18, extend the arm from above the vehicle, and move the bucket cart 8 closer to the high-altitude work location.

(Effects of the invention) This invention has the above-mentioned structure, and focuses on pillars such as utility poles that are erected at regular intervals along power distribution lines. Because the base is attached and the bucket for work at heights is supported by poles such as telephone poles, the structure is extremely simple and manufacturing is easy, unlike conventional buckets for work at heights that are integrated with the car. . Furthermore, the structure is simple and compact, making it convenient to store and transport. Therefore, when working at heights, the device must first be transported in a truck or the like during early morning hours or other times when there is little traffic, and then attached to a column, and the arm must be extended when working at heights. Since this device is installed on the column above the height of passersby and passing vehicles, it does not interfere with road traffic during work at heights, so work can be carried out safely and reliably.

Furthermore, when fixing this device to the column, the column is held between the two gripping pieces of the fixing part, thereby making it possible to firmly fix the device to the column.
In addition, in this device, the horizontal arm base is freely rotatable in the horizontal direction, and the horizontal arm is freely extendable and retractable in the longitudinal direction from one end of the horizontal arm base, and the vertical arm is also freely extendable and retractable in the vertical direction. You can carry the bucket to any location from where the fixed part is attached to the column. Therefore, by fixing the fixing part of this invention below the column, the worker can easily get on the bucket below the column, and then move the bucket to the target location and bring it close to the top of the column. This makes work easier.
