Description

[Detailed description of the invention] (Field of application of industrial robots) The present invention is equipped with a workbench at the upper end of the boom, and can be attached to tall pillars such as telephone poles and trees by itself, allowing work at any height. This article relates to methods and equipment for working at heights, in which workers and cargo are transported to different locations. (Prior art) When carrying a worker up to the top of a vertical columnar object such as a telephone pole or a tree, it is necessary to carry the worker up to a so-called high place where the moving vehicle is equipped with a lifting means as shown in Fig. 9. This was carried out using a work vehicle 90. (Problem to be solved by the invention) The above-mentioned aerial work vehicle has excellent mobility, but because it is integrated with a traveling vehicle such as a truck or crane, it is impossible to repurpose the vehicle. be. Additionally, the positions of vehicles and cranes are restricted during work, so when working around the entire circumference of a pillar-shaped object, it was necessary to move the vehicle according to the work position. Furthermore, it is necessary to stop the work vehicle close to the columnar object and surround it with a barricade, which poses problems such as interfering with traffic.

The present invention allows a worker to be placed on a columnar object and raised or lowered to any desired height.This allows the AM vehicle to be released during work, so it can be used in relatively narrow spaces without interfering with traffic. The purpose is to provide a method and device for working at heights. (Means for Solving the Problems) The high-altitude method according to the present invention for achieving the above object is as follows:
The boom of the working device is extended or lifted by a crane, and the device is attached to the support L by holding the support with a holding mechanism at the tip of the boom.

The feature is that the boom is then activated to move the workbench above the support to perform the work. In addition, the equipment for working at heights is
A clamping mechanism for the support body is composed of a pair of clamping parts equipped with an opening/closing mechanism, and a boom having a workbench at the tip is attached to the clamping mechanism so as to be able to rise and fall freely.
It is also possible to attach the clamping mechanism to the supporting mechanism via a rotatable mounting body around the clamping mechanism.

(Function) While placed on the transport means, extend the boom of the working device or lift it with a crane, etc., and clamp the support body with the support mechanism at the tip. Then, the boom 5 is retracted and the work platform is lifted from the transport means. Further, the boom is extended to raise the workbench to a working position above the support and work is performed. If necessary, the boom can be rotated around the support mechanism and the workbench can be moved to any position around the support, allowing for efficient work. (Example) Next, an example of the present invention will be described based on the drawings.

Fig. 1 is a front view of the high-altitude working device of the present invention, Fig. 2 is a plan view thereof, Fig. 3 is an enlarged front view of the clamping mechanism, Fig. 4 is a partially cutaway front view of the same, and Fig. 5 is the clamping mechanism. FIG.

First, the configuration of the high-place work device 8 used in the high-place work method will be explained.

The high-altitude working device A is provided with a packet 3, which is a workbench, at the upper end of a boom 2, which is attached to the negative side of a clamping mechanism 1 that can be opened and closed, so as to be able to rise and fall freely.

As shown in FIGS. 3 to 5, the clamping mechanism 1 consists of a pair of semicircular clamping parts 11 and 12 whose ends are rotatably supported on a shaft 10. Grooves 11a are cut into the outer peripheries of the clamping parts 11 and 12.

Furthermore, a cylinder 17 is fixed to the side of one of the clamping parts 1-2, and the end of the rod 18 of this cylinder 17 is pivotally supported by the other clamping part 11. Therefore, when the cylinder 17 is actuated, the clamping portion 11 rotates around the shaft 10, and the clamping mechanism 1 opens and closes. (See the imaginary line in FIG. 5) On the other hand, the clamping mechanism 1 is provided with a mounting body 23 for the boom 2.

This mounting body 23 has a protrusion 23a formed on the top cover along the tip thereof, and this protrusion 23a is slidably fitted into the groove 11a. A drive motor 19 is mounted on the top of the mounting body 23.
Configure. Gear l at the tip of the drive shaft of the second motor 19.
9a meshes with the upper ends of the outer peripheral surfaces of the clamping mechanisms 1] and 12, so that the rotation of the motor 19 causes the mounting body 23 and the boom 2 to rotate along the circumference of the clamping mechanisms. The boom 2 is provided with a tilting mechanism 21 for tilting downward L (vertical direction in FIG. 1), and is fixed to one side of the clamping mechanism 1. Furthermore, although the boom 2 of this embodiment has each rod nested in a nested manner to be extendable and retractable, the number of rods in the structure is not particularly limited, and the rods are not necessarily nested.

The packet 3 is attached to the tip of the boom 2 via an attachment portion 45. The crane 4 is attached to the L end of the mounting portion 45 so that it can be raised and lowered and rotated freely. In the figure, 41 is a winch and 42 is a wire. Next, we will explain how to work at heights using the above-mentioned equipment for working at heights. As shown in Fig. 6, the six packets 3 that transport the aerial work equipment IA to the work site are fixed to the truck T, and the boom 2 is extended to move it to the predetermined position of the columnar object S to be worked on. ．． In addition to the method described above, there is also a method for moving the high-place work equipment A to a predetermined position on the columnar object S, such as lifting it with a crane or the like. After that, the cylinder 17 of the clamping mechanism 1 is operated and the rond 18 is
is retracted and the clamping part 11 is rotated to open the clamping mechanism 1. Then, the columnar object S is positioned between the clamping parts 11 and 12, and the rod 18 is extended and clamped by the clamping mechanism 1 to fix the mounting IA to the columnar object S.

Thereafter, a worker is placed on the packet 3 and the boom 2 is raised to a working height. (See Fig. 7) As shown in Fig. 8, in this state, the tilting mechanism 21 is operated to tilt the boom 2 appropriately to position the packet 3 at an appropriate distance from the columnar object S, and perform the desired operation. I do.

During work, the packet 3 can be moved to the desired position by tilting or extending/retracting the boom 2 as necessary, and by activating the movable motor 19 of the mounting body 23 to rotate the boom 2 around the columnar object S. It can be placed in any position, enabling efficient work.

When moving the equipment 2ZA to truck T after the work is completed,
The above procedure can be performed in reverse.

As described above, according to this embodiment, high-place work can be performed easily and safely using a small-sized work device. Also,. Once the device is attached to the column, the truck is no longer needed, so it does not obstruct traffic. Furthermore, one truck can transport several pieces of equipment. (Effects of the Invention) As explained above, according to the present invention, the transport vehicle can be released during work because it can be fixed to the support body by itself. Moreover, it functions usefully even in narrow work sites, does not take up much space, and does not obstruct traffic. Work efficiency is improved because the workbench can be rotated around the support while the support mechanism is fixed to the support. Furthermore, since it is independent from the transport vehicle, storage management and storage can be carried out easily.
