Description

[Detailed description of the device] [Industrial applications]

The present invention relates to an aerial work vehicle, and more particularly, to an aerial work vehicle having a winch having a sub-boom near a bucket mounted at the tip of a boom.

[Background of device]

Conventionally, an aerial work vehicle as shown in FIG. 2 has been known. In the figure, 1 is a boom that can be lifted, retracted, and swiveled in an aerial work vehicle, 2 is a bucket attached to the tip of the boom 1,
3 is a winch equipped with a winch post 5 standing upright on a pivot base 4 of the boom 1 and the bucket 2 so as to be able to swing vertically and horizontally, 6 is a sub boom of the winch 3, 7 is a wire, 8 Is a hook, 9 is a pivot for pivotally supporting the winch body 3a on the winch post 5, and 10 is a winch sheave fixed to the tip of the sub-boom 6. By the way, for example, distribution line work is performed using such an aerial work vehicle. However, the workability of the conventional aerial work vehicle shown in FIG. Also, some problems remained from the viewpoint of safety. That is, an operator rides on the bucket 2 to perform various work such as distribution line work, but for work such as this distribution line work, two people are often required from the work contents. For example, two workers are required for the work performed using the wire crimping machine, the cutter, and the like. By the way, when two workers come to ride on the bucket 2, since the bucket 2 itself is not so large, it is difficult to work and the work efficiency becomes low. Moreover, not only is the work efficiency low, but when two people are working on the bucket 2 that is not so large, the bucket 2 is not large, so the worker is hard to move, and therefore the worker himself is difficult to balance. However, it also has the disadvantage of poor safety. Furthermore, the work range of the boom is regulated from the viewpoint of preventing the work vehicle itself from falling, but this regulation has a drawback that the larger the load is, the tighter the work range is, that is, the safe work range of the boom is narrow. .

[Disclosure of device]

An object of the present invention is to provide an aerial work vehicle having excellent work efficiency. An object of the present invention is to provide an aerial work vehicle having excellent work safety. Another object of the present invention is to provide an aerial work vehicle in which work efficiency and safety can be improved by simple means. The object of the present invention is an aerial work vehicle in which a winch having a sub-boom is provided in the vicinity of a bucket mounted at the tip of the boom, and the winch sheave is provided at one end and the handling device is provided at the other end. The mechanism is achieved by an aerial work vehicle characterized in that the mechanism is provided at the tip of the sub-boom so as to be rotatable and stopable.

【Example】

1 (a), (b) and (c) are views of an aerial work vehicle according to the present invention.
It is a perspective view, a top view, and a side view of the important section of an example. The present invention is also provided with the configuration of each part shown in FIG. 2, but detailed description thereof will be omitted. Reference numeral 11 denotes a groove formed on the tip of the sub-boom 6, reference numeral 12 denotes a shaft arranged on the groove 11, and the shaft 12 is attached to the sub-boom 6 by a pin 13 so as to be rotatable. ing. 14 is a sheave for winch provided at one end of the shaft 12,
The method of attaching the winch sheave 14 to the shaft 12 may be the same as the method of attaching the winch sheave 10 to the sub-boom 6 of the related art, and thus the details thereof will be omitted. Reference numeral 15 denotes a handling device which is provided at the other end of the shaft 12 and which has a function of firmly holding a tool such as an electric wire crimping machine or a cutter, or hooking an electric wire or the like. Reference numeral 16 denotes a stopper mechanism composed of, for example, a pin so that the shaft 12 can maintain the state shown in FIG.
The shaft 12 is maintained in the concave streak portion 11 of the sub-boom 6 by the action of, and the stopper mechanism is released in the state of FIG. The shaft 12 rotates counterclockwise in FIG.
The handling device 15 housed inside 1 is arranged at the tip of the sub-boom 6, and the winch sheave 14 is arranged at the recessed portion 11 of the sub-boom 6. When distribution work is performed using the aerial work vehicle configured as described above, the number of workers on the bucket 2 may be one. That is, if the electric wire crimping machine used for connecting the electric wires is held by the handling device 15, the electric wire can be connected even by one person. Further, the work using a tool such as a cutter can also be performed by one person by sandwiching these tools in the handling device 15 by one person. As described above, according to the aerial work vehicle of the present invention, the work that has been required by two people can be performed by one person, so that the labor cost for the work can be reduced and the cost can be reduced. In addition, the work range of the boom is regulated from the viewpoint of preventing the work vehicle itself from falling, but this regulation is tighter as the payload is larger, that is, the safe work range of the boom is narrower. As the number of persons from 2 to 1 decreases, the load becomes lighter, so that the safe work range of the boom becomes wider, that is, the work range without moving the aerial work vehicle becomes wider, and the workability also becomes better. Moreover, not only is the working cost low, but only one worker is required to ride on the bucket 2. Therefore, even if the bucket 2 itself is small, the movement of the worker is not restricted, and it is easy to move, so the working efficiency is improved. Furthermore, since the worker easily moves in the bucket 2, it is difficult to lose the balance, and the safety is increased accordingly. Further, the work using the winch and the work using the handling device can be switched by simply rotating the shaft 12 to which they are attached, and the workability is also good.

【effect】

An aerial work vehicle according to the present invention is an aerial work vehicle in which a winch having a sub-boom is provided in the vicinity of a bucket mounted on the tip of a boom, and a sheave for a winch is provided at one end and a handling is provided at the other end. Since the mechanism having the device is provided at the tip of the sub boom so as to be rotatable and stopable,
For example, when distribution line construction is performed, only one worker may ride on the bucket. In other words, if the wire crimping machine used to connect the wires is clamped by the handling device,
One person can perform the work of connecting the electric wire, and the work of using a tool such as a cutter can also be performed by one person by sandwiching these tools in the handling device. Since the work that has been done up to now can be done by one person, the labor cost of the work can be reduced by that much, the cost can be made low, and not only the work cost is reduced, but also one worker who rides on the bucket Because you can
Even if the bucket itself is small, the movement of workers is not restricted,
Workability is improved because it is easy to move, and because the worker is easy to move inside the bucket, it is less likely to lose balance and safety is increased accordingly, and the work range of the boom from the viewpoint of preventing the work vehicle itself from falling over. Is regulated, but if the number of workers becomes one from two, the load will be lighter, so the safe work range of the boom will be widened,
In other words, the range of work that can be performed without moving the aerial work vehicle is widened, and thus the workability is improved, and the work between the winch and the handling device can be easily switched. It has good characteristics, and has a feature that it has a simple structure for exhibiting these effects and can be provided at low cost.
