Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled aerial work vehicle used for aerial work, and more particularly to a battery-operated aerial work vehicle having an improved storage method of a battery as a power source. is there.

[0002]

2. Description of the Related Art This type of aerial work vehicle is used for indoor construction work, electric work such as wiring, desorption of objects, painting, etc. to save labor and improve safety at the construction site. To achieve this, a self-propelled battery-powered vehicle is used. Recently, such aerial work vehicles are often equipped with a rubber crawler type traveling device that can travel even on a rough road surface and does not damage the road surface during traveling.

3 and 4 are views showing a conventional example of an aerial work vehicle. The aerial work vehicle of FIG. 3 is a battery as a power source.
The (9) was placed between the rubber crawler (8) and the workbench (4). Further, in the aerial work vehicle of FIG. 4, the battery (9) is housed between the crawler traveling device (5-1) at the rear of the vehicle.

[0004]

However, the conventional aerial work vehicle described above has the following problems. In the aerial work vehicle shown in Fig. 3, the height of the floor surface of the workbench (4) is equal to or greater than the sum of the height of the rubber crawler (8) and the height of the battery (9). There was a problem that it was difficult to get on and off the floor of the workbench (4).

In the aerial work vehicle shown in FIG. 4, the floor height of the workbench (4) can be reduced, but the battery (9) interferes with the crawler traveling device (5-1) and the battery (9). There was a problem that it could not be stored unless the size of 9) was smaller than the required capacity.

An object of the present invention is to provide an aerial work vehicle capable of accommodating a battery having a required capacity without raising the floor surface of the workbench more than necessary.

[0007]

In order to solve the above-mentioned problems, the invention of claim 1 provides a gantry (1), traveling means (8) provided on both sides of the gantry, and a traveling direction of the gantry. The masts (2) and (3) provided on one side, and the drive means (5) and (6) provided on the other side in the traveling direction of the gantry to drive the traveling means and the mast on the gantry. A battery (9) which is arranged at a position surrounded by the traveling means, the mast, and the driving means, and serves as a driving source of the driving means, and is provided to be movable up and down on the mast, and is provided on a part of the floor surface of the battery. The elevator (4) is provided with an opening (12) formed corresponding to the position of the battery and a door (13) for opening and closing the opening.

[0008]

According to the present invention, an opening is formed in a part of the floor surface of the lift table, and an openable / closable door section is provided in the opening section, and the battery is mounted on the pedestal below the door section. Since it is stored, a large battery can be installed without raising the floor of the lift. Further, when the elevator is not raised (stored state), maintenance can be performed from the opening by opening the door on the floor of the elevator.

[0009]

The present invention will be described in more detail below with reference to the drawings and the like. FIG. 1 is a perspective view showing an embodiment of an aerial work vehicle according to the present invention, and FIG. 2 is a plan view, a front view and a side view showing an aerial work vehicle according to this embodiment. The aerial work vehicle of this embodiment is provided with a telescopic mast (2) on the front side of the upper surface of the gantry (1), and the worktable (4 ) Is fixed. The telescopic mast (2) is constructed so that the workbench (4) can be moved up and down by expansion and contraction by an elevating device (not shown) composed of a retractable hydraulic cylinder and a chain and the like housed inside. A traction motor (5) and a mission (6) are provided behind the gantry (1). A sprocket (7) is fixed to the output shaft of the mission (6), and the rubber crawler (8) is driven by the sprocket (7), so that the aerial work vehicle can travel.

The battery (9) is arranged at the center of the vehicle surrounded by the rubber crawler (8) on the base (1), the mission (6) and the telescoping mast (2). A protective cover (10) is provided. Floor of workbench (4)
In (11), at the position corresponding to the battery protection cover (10),
An opening (12) is formed, and a door (13) is provided in the opening (12) so as to be openable and closable via a hinge (14).

Next, the battery maintenance of the aerial work vehicle of this embodiment will be described. Battery maintenance is normally performed by raising the workbench (4) and then opening the battery protection cover (10). When the workbench (4) cannot be raised due to battery exhaustion or failure, etc., the floor surface (11) of the workbench (4)
Open the door (13) and add the battery protection cover (10).
Open.

The present invention is not limited to the embodiments described above, and various modifications and changes are possible, which are also included in the present invention. For example, the example of the crawler type has been described, but the wheel type may be used. Further, the door portion may be a sliding door type. Further, the shape of the work table (elevating table) is not limited to that shown in the figure. The mast may be arranged on the rear side and the motor and the mission may be arranged on the front side.

[0013]

As apparent from the above description, according to the present invention, the battery can be installed in the center of the vehicle without deteriorating the capacity of the battery. As a result, it is possible to greatly improve the ability of the operator to get on and off the platform and the ability to load and unload tools and materials. Further, even when the platform is lowered, the door portion can be opened to perform maintenance such as checking the liquid level of the battery or replacing the battery through the opening.
