Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an aerial work vehicle used for external work of buildings and the like.

[0002]

[Prior art]

 For example, an aerial work vehicle is used for external work of the building such as washing the outer wall of the building with water and repairing outer wall materials such as tiles. In the conventional structure of an aerial work vehicle, a boom is attached to the rear part of the truck bed, and a work bucket is attached to the tip of the boom. An operating device is provided in the work bucket. The aerial work vehicle is operated by an operator who works at a high place by operating an operating device in the work bucket.

[0003]

[Problems to be solved by the device]

 However, the above conventional aerial work platforms and their control methods had the following problems. That is, the work bucket is at a height of several tens of meters during work, and a worker who is not specialized in operating the boom in the work bucket pays attention to the condition of the grounding surface of the outrigger part and all surrounding trees or wires. It is difficult to control while handing out. In fact, there are many accidents where the work bucket collides with the outer wall of the building or the boom comes into contact with standing trees.Therefore, drivers' licenses and vehicle inspections have recently become obligatory. I lost control. Therefore, when working, a method has been adopted in which an operator who specializes in operating a work vehicle rides in a work bucket and operates the boom so that the worker can concentrate only on work in high places. However, if an operator, who is separate from the operator, is placed in a work bucket that is originally narrow, it is difficult for both the operator and the operator to move, which makes it difficult for the operator to work and also for the operator. Also, when the operator is on board, in the situation on the spot, it will be helpful for the operator, such as handing tools, helping the worker in high places work, and getting wet in the rain because there is no roof. Not a good working environment.

[0004]

[Means for Solving the Problems]

 Means of the present invention taken to solve the above problems are as follows. That is, the present invention is an aerial work vehicle in which a boom is attached to the bed of a self-propelled work vehicle, and a work bucket is attached to the tip of the boom. An aerial work vehicle in which an operation cabin equipped with an operation device for operating the boom is provided.

【Example】

 The present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 is a side view of an aerial work vehicle according to the present invention. Reference numeral A is an aerial work vehicle, which includes a self-propelled work vehicle 1. Outriggers 3 and 4 are provided at the front and rear of the luggage carrier 2 at the rear of the self-propelled work vehicle 1 to extend laterally to ground the legs to the ground and support the work vehicle A from falling. . A turntable 5 which is rotationally operated in the circumferential direction is provided at the rear of the loading platform 2. A base of a boom 6 is attached to the turntable 5. The boom 6 is extendable and retractable, and an arm 7 whose angle can be changed is provided at the tip. A work bucket 8 is attached to the tip of the arm 7. The work bucket 8 has a structure in which it is always kept horizontal regardless of the angle of the arm 7. An operation device 9 that can operate the boom 6 and the arm 7 is provided inside the work bucket 8 at a position where the work of the worker is not hindered. An operation cabin 10 is provided on the turntable 5 near the base of the boom 6. Like the operating device 9, an operating device 11 capable of operating the boom 6 and the arm 7 is provided inside the operating cabin 10.

(Operation) FIG. 2 is an explanatory view showing a working state. The operation of this embodiment will be described with reference to FIGS. Stop the aerial work vehicle A at the work position, spread the outriggers 3 and 4, ground the legs, and press the ground. This supports the aerial work vehicle A. An operator who is an expert in operating the boom 6 gets into the operation cabin 10 and operates the boom 6 and the arm 7 with the operation device 11 to unload the work bucket 8 from the loading platform 2. An operator who works in a high place gets into the work bucket 8. An operator operates the boom 6 and the arm 7 with the operation device 9 to bring the work bucket 8 close to a work place such as an outer wall of a building. At this time, the operator moves the work bucket 8 to the work position of the operator by paying attention to the surrounding standing trees, electric wires, signboards, buildings or the condition of the grounding surface of the outrigger part.

In this way, the operator and the aerial worker have different work positions, and the operator performs most of the operation of the boom 6 and the arm 7 in the operation cabin 10 in which the surrounding situation can be easily grasped. Therefore, the worker can concentrate on the work at a high place. Also, unlike the conventional case where an operator and an aerial worker are together, the operator does not have to do extra work such as helping the operator and can concentrate on the operation. Therefore, it becomes a good working environment where each specialized skill can be fully utilized, and safe and quick work becomes possible. Further, since the operator can operate inside the operation cabin 10 which is almost closed, even if the operator is forced to work in bad weather such as rainy weather, the operator is not easily affected by the bad weather, and the work safety is improved. The present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the claims for utility model registration.

[0008]

[Effect of device]

 The present invention has the above configuration and has the following effects. (A) The operator and the aerial worker work at different positions, and the operator performs most of the boom and arm operations within the operation cabin where it is easy to grasp the surrounding conditions. This allows the operator to concentrate on working at high places without worrying about unfamiliar boom and arm operations. Also, unlike the conventional case where an operator and an aerial worker are together, the operator does not have to do extra work such as helping the operator and can concentrate on the operation. Therefore, it becomes a good working environment where each specialized skill can be fully utilized, and safe and quick work becomes possible. (B) Since the operator can operate inside the almost closed operation cabin, even if it is unavoidable and the work is performed in bad weather such as rainy weather, the influence of bad weather is unlikely to be received and the work safety is improved. improves.
