Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is equipped with a manipulator pivotally supported by a plurality of pivots on the outer circumference of a workbench, for example, in high-altitude work to efficiently perform a predetermined high-altitude work. It relates to an aerial work vehicle equipped with a manipulator that is often used.

[Related technology and problems]

When performing work at high places with conventional work platforms, such as erection of electric wires on pillars, dust removal work attached to the insulator, and salt removal work, the worker mounts on the workbench equipped at the tip of the boom. The actual situation is that the above-mentioned predetermined work is carried out.

In such a conventional work platform for aerial work, the work platform originally equipped with the tip of a boom that can be undulated, extended and retracted, and extended to the highest place possible, and the worker who boarded the work platform described above. Its main purpose is to carry out such various operations. Therefore, for example, live work during power transmission (work in a workbench with good insulation that protects against electric shock), as well as work that is dangerous if workers directly perform various work at high places, There are various restrictions on various types of work that require time-consuming simple work, or even work where the work environment is extremely poor and that poses a health problem. In reality, another work means is not found, and therefore, when carrying out the work, it is the actual situation that the workbench is provided with various safety equipment corresponding to the work.

As a solution to the above-mentioned various problems, an operator on the workbench operates a predetermined operation lever to remotely control various work machines mounted on the outer circumference of the workbench to perform the desired work at a high place. There is a demand for the development of an aerial work vehicle that can be done, but at the present time, the aerial work vehicle that employs such a manipulator system in earnest has not been developed.

[Means and Actions for Solving Problems]

The present invention has been made in view of the above circumstances, and its purpose is to mount a manipulator pivotally supported by a plurality of pivots on the outer circumference of a workbench, for example, in a work at a high place to provide a predetermined height. The purpose is to provide an aerial work vehicle equipped with a manipulator for efficiently performing work at a place.To this end, a turntable mounted on a bogie or the like is attached with a boom that is undulating and retractable, and a predetermined work is performed on the boom. In an aerial work vehicle equipped with a platform, a substantially T-shaped base in plan view is attached to the tip of the boom so as to be rotatable in a horizontal plane, and a protrusion extending from substantially the center of the base is provided. The workbench is pivotally attached to the tip so that it can swing,
A pair of manipulators pivotally supported by a plurality of pivots and capable of changing direction in a predetermined direction are attached to the left and right ends of the base, and operation members for remotely controlling the manipulators are arranged on the workbench.

[Action]

Since the present invention adopts the above-mentioned configuration, the base can be swung about 90 degrees with respect to the boom, and the work table can be swung about 90 degrees with respect to the base. Can be stored compactly. In addition, since it is possible to swing only the work table with respect to the manipulator, the worker can always perform a predetermined work while visually observing the tip of the manipulator. Therefore, various works at high places can be performed accurately and safely. And it can be done quickly.

〔Example〕

Hereinafter, one embodiment of an aerial work vehicle equipped with a manipulator according to the present invention will be described in detail with reference to the attached FIGS. 1 and 2.

In the figure, reference numeral 1 is a chassis, on which a turntable 2 is rotatably mounted, and the turntable 2 is swung by a hydraulic motor. The turntable 2 has a telescope shape, and a boom 3 extending and retracting is pivotally supported by a hydraulic cylinder (not shown) provided inside the turntable 2. The boom 3 is provided between the turntable 2 and the boom 3. The hydraulic cylinder 4 is configured to be vertically undulated by expansion and contraction. Further, a base (manipulator mount, which will be described later) 5 formed in a substantially T-shape is attached to the tip of the boom 3 so as to be pivotally supported by a first pivot 3a, and a protrusion extending from the center of the base 5. A workbench 6 is pivotally supported by a second pivot 5c at the tip of 5a, and is attached to the workbench 6 so that the workbench can swing and bend and rotate in a predetermined direction.
Manipulators 7, 7 capable of bending, rotating, and gripping are attached to the ends of the extending portions 5b, 5b protruding to the left and right of the base 5.

By the way, for remote control of the manipulators 7, 7 attached to the left and right of the base 5, the left and right operation members provided inside the workbench 6 (in this embodiment, a master arm system is adopted, which will be described below as a master arm). 8) Manipulation of 8 and 8 is performed.

In the figure, 9 is an operation panel in which knobs for various operators are arranged.

The operation of the aerial work vehicle equipped with the manipulator according to the present invention will be described below based on the above configuration.

That is, the manipulators 7 and 7 are remotely controlled by the operation of the master arms 8 and 8 mounted in the workbench 6 to smoothly perform a predetermined work. In the present invention, in particular, the manipulators 7 and 7 and the workbench 7 are 6 for the first and second pivots 3
Since they are pivotally supported by a and 5c and are connected via the base 5, the maneuverability of both members is much wider than that of the conventional one, and the workability is excellent. , 7 can be positioned, as shown in the figure, the manipulators 7, 7 and the workbench 6 can be set in a straight line (considering the direction of the passenger) to perform a predetermined work. Since it is possible, it is extremely easy, accurate and safe to operate the manipulators 7, 7 by manipulating the master arms 8, 8 in the work table 6.

Further, since the manipulators 7 and 7 and the workbench 6 can be respectively rotated at arbitrary angles, the boom 3 is reduced and the workbench 6 is lifted from the work platform after a predetermined work is completed. In the case of positioning it on the front cabin of No. 1, it is sufficient to return to the state before the boom 3 shown in the same figure is unfolded, so that the workbench 6 and the manipulators 7, 7 can be stored very easily in a compact manner.

[Effect of device]

As described in detail above, the present invention attaches a boom that is undulating and retractable to a turntable equipped on a trolley,
In an aerial work vehicle equipped with a work table for performing a predetermined work on the boom, a substantially T-shaped base in plan view is attached to the tip of the boom so as to be rotatable in a horizontal plane. The workbench is pivotally attached to the tip of a protrusion extending from substantially the center of the base, and the left and right ends of the base are pivotally supported by a plurality of pivots to direct in a predetermined direction. A pair of convertible manipulators are attached, and operating members for remotely controlling each of the manipulators are arranged on the work table, so that the base is substantially
Since it can be turned 90 degrees and the work table can be swung about 90 degrees with respect to the base, it can be stored compactly. In addition, since it is possible to swing only the work table with respect to the manipulator, the worker can always perform a predetermined work while visually observing the tip of the manipulator, and therefore various work at high places can be performed accurately and safely. In addition, it has various excellent effects such that it can be performed quickly.
