Description

[Detailed Description of the Invention] (1) Industrial field of application The present invention is an aerial work vehicle in which the aerial work device is hidden by a body so that the aerial work device cannot be seen from the outside when stored. It is about.

(2) Conventional technology A turntable is rotatably mounted on the upper front surface of the vehicle body or the upper rear surface of the vehicle body, and a boom is erected and pivotally attached to the turntable. The work vehicle has been conventionally known as described in, for example, Japanese Utility Model Laid-Open No. 64-39400.

(3) Problems to be solved by the invention The conventional aerial work vehicle has a turntable rotatably mounted on a vehicle body, and a boom having a workbench attached to its tip is pivotally attached to the worktable at an aerial position. Since the equipment was not equipped to be hidden from the outside, the work equipment at high places could be seen from the outside, and it was too loud for a vehicle to be used for other service work, etc. was there.

(4) Means for Solving the Problems In order to solve the above problems, the present invention provides a turntable provided on a vehicle body so as to be freely rotatable, and a boom pivotably attached to the turntable. In an aerial work vehicle equipped with an aerial work device including a workbench attached to the tip of the boom, a body mounted on a vehicle body for accommodating the aerial work device inside and the aerial work device And a lifting device for lifting the turntable up and down so as to project above the body.

(5) Operation With the above configuration, when the work at a high place is not performed as when traveling, the lifting device is operated to lower the turntable, and the work device at a high place including the turntable, the boom and the workbench is mounted on the body. It is stored and stored inside so that the turntable and boom cannot be seen from the outside, and when performing work in high places using the aerial work device, operate the lifting device to raise the turntable, After projecting the aerial work device above the body, the turntable and boom are operated to move the workbench to an arbitrary position, and work is performed from inside the workbench.

(6) Embodiment An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, an aerial work vehicle covers the vehicle body (1) with a body (3) integrally formed with a driver's seat (1a) for operating the work vehicle. Body (3)
A recessed portion (4) for accommodating the aerial work apparatus (A) is provided in the center of the upper surface of the body, and is housed in the body (3) at the time of storage at the left, right, front and rear of the vehicle body (1), and when used (3)
An outrigger (2) is provided which projects more obliquely outward and is grounded. An aerial work device (A) is a lifting device (up and down) for moving up and down between a stowed position housed inside a body (3) and a working position protruding above the body (3) on a vehicle body (1). 6), a turntable (7), a telescopic boom (8) whose base end is pivotally supported by the turntable (7) and is connected in a telescopic manner, and a distal end of the telescopic boom (8). It consists of a workbench (9) that is held in equilibrium, and the telescopic boom (8) is a telescopic device (not shown).
The telescopic boom (8) and the workbench (9) are expanded and contracted by the turntable (7) and the telescopic boom (8). ) Is located inside the body (3) in the retracted position, it is housed inside the recess (4) so that the work implement (A) cannot be seen from the outside. Doors (11) for utilizing the inside of the body (3) as a storage portion are provided on the left and right side surfaces of the body (3).

As shown in FIG. 3, in the lifting device (6), an inner frame (12) is vertically erected on the upper surface of a turning ring (5) rotatably mounted on a vehicle body (1). An outer frame (13) is vertically slidably fitted around the outer periphery of (12), and a turntable (7) is attached to the upper surface of the outer frame (13). Outer frame (13) is outer frame (13) and inner frame (12)
The telescopic cylinder (14), which is built in and has one end attached to the lower end of the inner frame (12) and the other end attached to the upper end of the outer frame (13), slides up and down by extension and contraction.

With the above configuration, when performing work using an aerial work vehicle, the outrigger (2) is projected obliquely outward of the body (3) to be grounded, and the vehicle body (1) is supported by the outrigger (2). After that, the telescopic cylinder (14) is extended, the outer frame (13) is slid upward with respect to the inner frame (12), and the aerial work device (A) is projected above the body (3). In this state, the telescopic boom (8) is hoisted and extended, the lifting device (6) is swung to move the workbench (9) to an arbitrary position, and work is performed from inside the workbench (9). When the work at a high place is not performed, the telescopic boom (4) is contracted to lower the ups and downs, and the lifting device (6) is swung to position the telescopic boom (8) to the retracted position, and then the telescopic cylinder (14). And the outer frame (13) is slid downward with respect to the inner frame (12) to store the high-altitude work device (A) inside the recessed portion (4) of the body (3) and raise it from the outside. Make the work device (A) invisible. In this state, outrigger (2)
Can be stored in the body (3), and the aerial work vehicle can be moved to any position.

(7) Effects of the Invention As described above, according to the present invention, the aerial work apparatus composed of the turntable, the telescopic boom and the workbench is housed inside the body when the aerial work is not performed, and the aerial work apparatus is installed higher than the outside. The work equipment is hidden and the work equipment at height is projected above the body when performing work, which improves the image as a vehicle used for other service work and Since the turntable can be used for storage and the like, and the turntable can be moved up and down, the boom length can be shortened and the work vehicle can be downsized. It is effective for improving the workability of the field work vehicle and expanding the range of use.
