[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation device of a work handling machine used for attaching a wall material or a ceiling material to a wall surface or a ceiling surface at an indoor building site or the like.

[0002]

2. Description of the Related Art When mounting a wall material on a wall surface or mounting a ceiling material on a ceiling surface at an indoor construction site, etc., an operator transports a heavy wall material to a mounting location and holds the vertical position. Since the ceiling material is transported to the installation location and held in a horizontal position, the work requires labor and is not only troublesome, but also can cause accidental falling. It is a danger. Therefore, the present applicant first attaches a manipulator that swings up and down and moves horizontally to the traveling carriage, attaches a work support member to the tip of the manipulator, supports the work with the work support member, and operates the work manipulator. Has applied for a work handling machine capable of transporting the machine upward.

[0003]

The operation of the manipulator of such a work handling machine is controlled by an operation box provided on the traveling trolley, so that the tip of the manipulator is separated from the operation box, and the manipulator is operated while observing the movement of the tip of the manipulator. Poor operability is difficult.

Therefore, an object of the present invention is to provide an operating device for a work handling machine which can solve the above-mentioned problems.

[0005]

Means for Solving the Problems A main body 13 is attached to the traveling carriage 1, and the main body 13 is vertically swung by a cylinder 29,
A manipulator is provided by attaching a parallel four-bar link that is manually moved horizontally, and a mounting bracket 40 is mounted on the distal end of the manipulator so as to swing freely on a swing longitudinal axis 41. A horizontal axis 43 that is 90 degrees out of phase with the vertical axis 41 is rotatably supported, and a mounting board 47 is swingably mounted on the rotating plate 42 in a horizontal orientation and a vertical orientation. 47
A swinging cylinder 49 is connected to the rotating plate 42 and a work supporting member 50 is mounted on the mounting board 47 to form a work handling machine. At the tip of the manipulator, pressure is applied to the cylinder 29 and the cylinder 49. An operating device for a work handling machine, comprising an operating member for switching an operating valve for supplying oil.

[0006]

[Work] The turning plate is turned so that the mounting board 47 is positioned below the horizontal axis 43, and the mounting board 49 is turned sideways with respect to the turning plate by the cylinder 49 so that the work supporting member 50 is turned downward. By doing so, the work placed horizontally on the floor can be supported by the work supporting member 50. In this state, the work is brought to the vertical posture by setting the mounting board 47 to the vertical posture by the cylinder 49, so that the work can be transported to the wall surface and held in the vertical posture. At this time, the work is inclined left and right by swinging the mounting bracket 40, so that the work can be made parallel to the wall surface. Thus, a work placed horizontally on the floor can be easily attached to the wall. By setting the mounting substrate 47 to the horizontal position by the cylinder 49 from the state of the above-mentioned vertical position of the work, the work becomes a horizontal position. In this state, the work can be transported to the ceiling and held in a horizontal position by swinging the parallel four-bar link up and down, moving horizontally, and running the traveling cart. Thus, a work placed horizontally on the floor can be easily mounted on the ceiling. In addition, since the operating member is attached to the tip of the manipulator, the operating member is near the work supporting member 50, and the manipulator can be vertically rocked and the mounting board 47 can be rocked near the work supporting member 50. . Thus, the operation can be performed while watching the work, so that the operation can be finely performed.

Then, the workpiece moves upward as shown in FIG. 6, and when the cylinder 49 is extended, the workpiece E assumes a horizontal posture as shown in FIG. Therefore, as shown in FIG. 8, the movable mast 6 is raised while supporting the work E placed on the floor, and at the same time, the four-joint link mechanism is swung upward to bring the work E into the vertical posture. The work E can be transported to the wall F as shown in FIG. Similarly, the work E placed on the floor as shown in FIG. 10 can be transported to the ceiling G as shown in FIG. 11 and held in a horizontal posture. Since the driver's cab 7 is provided in the above embodiment, a plurality of works E are placed on the driver's cab 7 as shown in FIGS. Since the work E can be moved upward to be mounted on the wall F or the ceiling G, the work can be extremely easily and safely mounted on the wall F or the ceiling G. The work supporting member may be a clamp or the like.

[0011]

The rotating plate 42 is rotated so that the mounting substrate 47 is positioned below the horizontal axis 43, and the mounting substrate 49 is oriented laterally with respect to the rotating plate 42 by the cylinder 49 so that the work supporting member 50 faces downward. By doing so, the work placed horizontally on the floor can be supported by the work support member 50. In this state, the work is brought to the vertical posture by setting the mounting board 47 to the vertical posture by the cylinder 49, so that the work can be transported to the wall surface and held in the vertical posture. At this time, the work is inclined left and right by swinging the mounting bracket 40, so that the work can be made parallel to the wall surface. Thus, a work placed horizontally on the floor can be easily attached to the wall. By setting the mounting substrate 47 to the horizontal position by the cylinder 49 from the state of the above-mentioned vertical position of the work, the work becomes a horizontal position. In this state, the work can be transported to the ceiling and held in a horizontal position by swinging the parallel four-bar link up and down, moving horizontally, and running the traveling cart. Thus, a work placed horizontally on the floor can be easily mounted on the ceiling. In addition, since the operating member is attached to the tip of the manipulator, the operating member is near the work supporting member 50, and the manipulator can be vertically rocked and the mounting board 47 can be rocked near the work supporting member 50. . Thus, the operation can be performed while watching the work, so that the operation can be finely performed.
