JPH0625492Y2 - Bucket operating device arrangement structure for aerial work vehicles - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] According to the present invention, boom-related operations such as ups and downs, expansion and contraction, and swinging of a boom are performed by a control lever or the like of an upper operation unit mounted on the connecting side of the boom. Related to the bucket operation device arrangement structure for aerial work vehicles in which work related operations in the bucket such as live line work can be performed by the control lever of the upper operation unit equipped at a position other than the boom connection side Is.

[Prior art and its problems]

For example, a boom is equipped with a bucket at the tip of a boom that can be undulated, extended, retracted, and swiveled, and an operator rides on the bucket and operates the upper operation part to use boom-related operations such as undulation, stretching, and swiveling of the boom, or an attachment tool. In the conventional aerial work vehicle capable of performing the work-related operations described above, since the equipment of the upper operation section for the bucket is concentratedly installed in one place on the boom connection side, the boom-related operation, that is, the boom However, when performing boom undulation, extension and contraction, turning, etc., it is convenient because it is easy to operate because the upper operation part is equipped on the boom connection side of the bucket, but the work related operation using the attachment tool, that is, the puller When performing a predetermined work at a high place using an attachment tool such as Since it has to be vertical, the upper operation part is located on the back or side of the operator, so the various control levers are in the opposite direction to the operator's normal selfishness and must be operated backwards, which is very complicated. However, there was a problem that it was difficult and the work efficiency was extremely poor.

[Means and Actions for Solving Problems]

The present invention has been made in view of the above circumstances, and its purpose is to perform boom-related operations such as boom up / down, extension / contraction, and turning by using a control lever or the like of an upper operation unit equipped on the connecting side of the boom. It is to provide a bucket operating device arrangement structure for an aerial work vehicle that can be performed and work related operations in the bucket such as live line work can be performed by the control lever of the upper operation unit equipped at a position other than the connecting side of the boom.
Therefore, in an aerial work vehicle in which a bucket is equipped at the tip of the boom, and the bucket is equipped with upper operation parts such as various control levers, all or a part of the various control levers in the upper operation part are It is installed in parallel at different positions so that the operator can use it properly according to the work purpose and direction.

[Action]

Since the above-mentioned configuration is adopted, the operator can selectively use the upper operation section according to the operation position / direction of the boom-related operation and the in-bucket operation-related operation. The work efficiency is remarkably improved, and the operator can work in high places extremely safely.

〔Example〕

An embodiment of a bucket operating device arrangement structure for an aerial work vehicle according to the present invention will be described in detail below with reference to the drawings.

In the figure, 1 is a bucket mounted on the tip of the boom 2, and 3 is mounted on the side of the boom 2 for operating the boom 2.
That is, various upper control levers 4 for performing ups and downs, expansion and contraction, turning of the boom 2, and the like are upper operation levers having the same function as the above various upper control levers 3 or a function slightly independent from the upper control levers 3. Is equipped with special operation levers 4a, 4b, etc., which are operated especially on the tip side of the bucket 1.

The operation of the bucket operating device arrangement structure for an aerial work vehicle according to the present invention having the above-described configuration will be described below.

That is, the bucket operating device arrangement structure for an aerial work vehicle according to the present invention has various upper control levers 3 which are functional in operating the boom 2 on the side of the boom 2 around the periphery of the bucket 1.
And the upper end operation levers 4a, 4b related to work at a high position, which is less related to the operation of the boom 2, that is, the tip side of the bucket 1, and the attachment tool such as an impact wrench. Since it is equipped with a lever etc. for operating the
It is very easy to operate the bucket 1 left / right, up / down, etc. according to the work content, and when the operator performs a predetermined work at a high place, he / she works backward as he / she does with the upper operation lever as a back while performing the work as usual. Thus, there is no need to operate the upper operation lever and the like, and there is no difficulty in operation, and extremely safe and efficient work in high places can be performed.

[Effect of device]

As described above in detail, according to the present invention, a bucket is provided at the tip of the boom, and an aerial work vehicle in which the bucket is equipped with upper operation parts such as various control levers. All or a part of the above are separately installed in parallel at different positions of the bucket, and the operator can selectively use them according to the work purpose and direction. It is possible to selectively use the upper operation part depending on the operation position and direction, so the operability and work efficiency of various control levers are significantly improved, and the operator can perform high-altitude work extremely safely. Has excellent effect.
