Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerial work vehicle with a manipulator for newly installing or maintaining a distribution line installed at a high place for distribution line work. In particular, the present invention relates to a method of storing a manipulator in a work vehicle and attaching it to a bucket provided at the tip of a boom.

[0002]

2. Description of the Related Art Conventionally, a manipulator is generally fixedly installed at a predetermined position of a bucket (for example, Japanese Utility Model Laid-Open No. 1-143220). Also, there is a winch supporting column provided at the tip of the boom in which a manipulator is detachably mounted (for example, JP-A-64-60212).

[0003]

However, in the former case, unless the storage posture of the manipulator having a relatively large weight is devised, the manipulator protrudes from the tip of the vehicle and the center of gravity moves to the front part during traveling, which causes unstable running. Invited,
There was a problem that the manipulator equipped with necessary functions could not be installed due to the restriction of the allowable weight on the boom due to the turning angle regulation of the vehicle. In addition, while the latter can solve the former problem, the method of storing it in the vehicle is not clearly stated, and since the manipulator is rotatably mounted on the winch support, the distribution line of the manipulator can be referenced based on the bucket. There is a problem in that the work position for can not be specified. Therefore, an object of the present invention is to provide a manipulator mounting method for a power distribution work vehicle that can reduce the allowable weight on the boom related to the turning angle regulation of the vehicle, can stably drive, and can specify the rotational position of the manipulator with respect to the distribution line. To do.

[0004]

In order to solve the above problems, when the vehicle is running, the manipulator is stored in a storage device fixed to the bed of the vehicle in a posture that minimizes space,
During power distribution work, the manipulator is hoisted by the winch provided in the bucket, fixed to the fixed seat of the bucket, and then the wiring and piping for manipulator operation are connected.

[0005]

When the vehicle is running, the manipulator does not stick out from the tip of the vehicle, and the center of gravity of the vehicle is lowered. When a manipulator is attached to the tip of the boom for wiring work, the work position of the distribution line with respect to the bucket can be specified.

EXAMPLES Specific examples of the present invention will be described below with reference to FIGS. FIG. 1 is a side view (a) and a rear view (b) showing a traveling state of a vehicle. At the rear of the vehicle 1,
The turning base 2 is fixed to the bed of the vehicle. A boom 3 having a plurality of telescopic arms inside is rotatably provided above the swivel base 2. A cylinder 4 is connected to the middle of the boom 3 by a pin or the like, and the boom 3 which is rotated by the expansion and contraction of the cylinder 4 is folded so as to be substantially horizontal with respect to the platform. A bucket 5 having a manipulator mounting portion 6 on the front surface provided at the tip of the boom 3 is fixed to the roof of the driver's seat. A manipulator storage device 7 is fixed to the floor surface below the boom 3 between the swivel base 2 and the driver's seat. The manipulator storage device 7 includes a manipulator 8
Each arm is folded and stored and fixed in a posture that minimizes the space. FIG. 2 is a side view showing the lifting operation of the manipulator. Before starting the work, the cylinder 5 is extended and the boom 3 is rotated to hold the bucket 5 at a high place. Next, the manipulator 8 is detached from the manipulator storage device 7, the hook 11 attached to the tip of the wire 10 of the winch 9 is hooked on a hanger such as an eyebolt provided on the manipulator 8, and an operator who rides on the bucket 5 The winch 9 is operated to lift it up to the manipulator mounting portion 6 provided on the front surface of the bucket 5. Figure 3
Is a front view (a) and a side sectional view (b) showing a manipulator mounting portion, and FIG. 4 is a front view (a) and a side sectional view (b) showing a manipulator mounting state. A fixed seat 13 of a flat plate-shaped manipulator 8 having a height H and a width L is fixed to the front surface of the manipulator mounting portion 6. A seat 14 left uncut at a height h and a depth t is provided below the flat surface of the fixed seat 13. The upper surface horizontal portion of the seat 14 is used as the Z-direction positioning portion 14Z. A vertical groove 15 having a width of 1 is cut in the central portion of the seat 14 in the width L direction, and both side surfaces of the groove 15 are used as Y direction positioning portions 15Y. The upper rectangular recess of the Z-direction positioning portion 14Z becomes the X-direction positioning portion 16X. The X direction positioning portion 16X is provided with a plurality of female threads 17 for attaching the manipulator. That is, the fixed seat 13 is formed with a T-shaped recess serving as a reference surface for positioning in the X, Y, and Z directions. On the other hand, the manipulator mounting portion of the manipulator storage device 7 is also formed with the same recess as the T-shape provided on the fixed seat 13. The manipulator mounting portion 6 and the manipulator housing 7 are provided with a similar-shaped convex portion that fits in a T-shaped concave portion provided on the manipulator storage device 7 on the mounting base of the manipulator 8. The convex portion provided on the manipulator 8 is fitted into the concave portion provided on the manipulator mounting portion 6, and the positions in the X, Y and Z directions are determined as shown in FIG. Fixed to.

[0007]

Since the manipulator is detachable and is stored / fixed in the luggage carrier, the manipulator does not protrude from the vehicle, the center of gravity of the vehicle is lowered, and stable traveling is possible. Since the manipulator is fixed to the bucket at the manipulator mounting portion having a positioning function, the orientation of the manipulator is determined by the swinging / rotating angle of the boom, so that the working position of the manipulator with respect to the distribution line can be specified.
