Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to improvement of a manipulator tool that is used by being held by the hand of a manipulator mounted on the tip of a boom of an aerial work vehicle or the like, and is particularly suitable for the intended work when it is held by the hand of the manipulator. The present invention relates to a manipulator tool capable of adjusting the orientation of the manipulator tool depending on the state.

[0002]

[Prior art]

 Conventional work at height, For example, electric wire replacement work performed by electric power companies, Most of the work such as adding wires or replacing transformers, Generally, a worker rides on the bucket of an aerial work vehicle equipped with a bucket at the end of the boom, We carry out various high-altitude work, Since there is a danger of electric shock when performing high-voltage hot line work, As shown in Figure 1, Equipped with an operation cabin 3 at the tip of the boom 2, An aerial work vehicle 1 equipped with a manipulator 4 in front of the operation cabin 3 was developed, When carrying out the above-mentioned hot line work, With the hand 4b equipped at the tip of the slave arm 4a of the manipulator 4, For example, a tape winding tool for electric wires, Peeling tool, Wire polishing tool, At present, the manipulator tool 5 typified by a nut attachment / detachment tool is clamped to perform a predetermined work.

[0003]

[Problems to be solved by the device]

 However, in the manipulator tool 5 held by the hand 4b of the conventional manipulator 4, the grip portion 5a held by the hand 4b has a quadrangular shape as shown in an example of FIG. The holding angle of the manipulator tool 5 was limited to four directions. Therefore, depending on the angle of the manipulator tool 5 clamped by the hand 4b, even when the work at the intended location can be performed, the clamping angle of the conventional manipulator tool 5 by the hand 4b is 4 degrees. Since it can only pinch in which it can be changed only in the direction (rotate by 90 degrees for adjustment), it has a complicated problem that the boom 2 must be moved or the position of the manipulator 4 must be moved.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above problems, and an object of the present invention is to improve a manipulator tool that is used by being held by a manipulator hand equipped at the tip of a boom of an aerial work vehicle or the like. Therefore, it is an object of the present invention to provide a manipulator tool capable of adjusting the orientation of the manipulator tool to an optimal state for the intended work especially when the manipulator tool is clamped by the manipulator hand. In the manipulator tool used in the manipulator equipped at the tip of the boom of a car, etc., the grip of the tool held by the manipulator's hand should have a polygonal shape with at least a pentagon.

[0005]

[Action]

 With the above configuration, the grip of the manipulator tool has a polygonal shape even when the boom is in contact with an obstacle and the manipulator mounted at the boom tip cannot be moved. Since the angle of the manipulator tool held by the hand can be changed subtly, the working range of the manipulator can be expanded and safe and efficient live work can be performed.

[0006]

【Example】

 An embodiment of a manipulator tool according to the present invention will be described in detail below with reference to FIGS. 1 and 2. In the figure, 1 is an aerial work vehicle. This aerial work vehicle 1 has a turntable rotatably mounted on the front part of the vehicle body, a telescopic boom 2 having a base end pivotally mounted on the top of the turntable, and a boom 2 at the tip of the boom 2. It is composed of an operation cabin 3 on which an equipped worker is aboard, and a slave arm 4a of a manipulator 4 mounted in front of the operation cabin 3.

The hoisting operation of the boom 2 is performed by expanding and contracting the hoisting cylinder disposed between the turntable and the boom 2, and the hoisting operation of the boom is performed by a telescopic cylinder (not shown in the figure) built in the boom 2. It is performed by expanding and contracting. The operation cabin 3 is provided with an operation device (not shown) for controlling the operation of the boom 2 and the like, and a master arm (not shown) of the manipulator 4. The manipulator tool 5 typified by, for example, an electric wire tape winding tool, a peeling tool, a wire polishing tool, a nut attaching / detaching tool, etc. is held at the tip of the slave arm 4a of the manipulator 4 to perform a predetermined work.

By the way, the outer shape of the grip portion A held by the hand 4b of the manipulator 4 of the manipulator tool 5 is a pentagonal or more polygonal shape, for example, a hexagon in the present embodiment, and the manipulator is held by the hand 4b. The holding angle of the tool 5 is configured so that it can be adjusted by 60 degrees, which is finer than 90 degrees in the case of the conventional quadrangle.

The operation of the manipulator tool according to the present invention will be described below based on the above configuration. That is, in the manipulator tool 5 according to the present invention, the outer shape of the grip portion A held by the hand 4b of the manipulator 4 is formed into a polygonal shape of a pentagon or more. Even when the equipped manipulator 4 cannot be moved, since the grip portion A of the manipulator tool 5 has a polygonal shape, the gripping angle with the hand 4b of the manipulator 4 can be finely adjusted for gripping. Therefore, the work range of the manipulator 4 is expanded, and safe and efficient live line work can be performed.

[0010]

[Effect of the device]

 As described in detail above, the present invention is a manipulator tool for use in a manipulator mounted on the tip of a boom of an aerial work vehicle or the like, and the outer shape of the grip portion of the tool clamped by the hand of the manipulator is at least pentagonal. Since it has a polygonal shape, the grip of the manipulator tool has a polygonal shape even when the manipulator mounted at the tip of the boom cannot be moved due to the boom coming into contact with an obstacle. Since it is possible to finely adjust the gripping angle with this hand, the working range of the manipulator can be expanded, and there are various excellent effects such as safe and efficient live-line operation.
