Description

[Detailed Description of the Invention] (1) Field of Industrial Application The present invention relates to a guide light for guiding a boom of a work platform such as an aerial work vehicle at night when the boom is stored in the boom rest.

(2) Conventional technology When the boom of an aerial work vehicle or the like is stored in the boom rest at night, the operator operates the operating device from the work platform to store the boom while checking the boom rest in the dark. It was

(3) Problems to be solved by the invention Conventionally, when a boom is stored in a boom rest after work by using a work platform for aerial work at night, the position of the boom rest is not good because the surroundings are dark. There was a problem that it was hard to grasp and accidentally damaged the cabin.

(4) Means for Solving the Problems In order to solve the above problems, the present invention includes a boom pivotally mounted on a turntable rotatably mounted on the vehicle body so that the boom can be raised and lowered. In a work vehicle in which a boom rest is erected, a guide light for guiding the boom at night is provided on the upper surface of the boom rest on which the boom is placed when retracted.

(5) Operation With the above configuration, when the work is performed at night using a work vehicle for aerial work and the boom is retracted after the work is completed, the guide light provided on the upper surface of the boom rest is turned on to allow the operator to perform boom operation. The position of the boom rest is grasped by the position of the light of the guide light that hits the lower surface, and the boom is stored in the boom rest.

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

As shown in FIG. 3, an aerial work vehicle is provided with outriggers (2) for supporting the vehicle body (1) on the front left and right side portions and the rear left and right side portions of the vehicle body (1), respectively. ), A turntable (3) is rotatably mounted on the turntable (3), the base end of a telescopic boom (4) is pivotally supported on the turntable (3), and the telescopic boom (4) has a built-in telescopic device (not shown). And the work table (6) is attached to the tip of the telescopic boom (4) while the telescopic boom (4) extends and retracts and the hoisting cylinder (5) having both ends pivotally attached to the turntable (3) and the telescopic boom (4) extends and retracts. Are balanced, and the telescopic boom (4) is stored in a boom rest (7) standing on the vehicle body during traveling.

As shown in FIG. 1 and FIG. 2, on the upper surface of the boom rest (7), a pair of guide lights (8) are provided on the left and right, and the guide light (8) includes a telescopic boom (4) and a boom rest (8). 7) It is embedded so that the light travels straight toward the lower surface of the telescopic boom (4) when it is directly above, and when the telescopic boom (4) is stored in the boom rest (7) at night. ,
The position of the boom rest (7) can be accurately grasped by the position of the light of the guide light (8) that hits the lower surface of the telescopic boom (4), and the operating device (9) provided on the workbench (6) can be used. The telescopic boom (4) is stored in the boom rest (7) by operation, and since the guide light (8) does not protrude from the upper surface of the boom rest (7), the telescopic boom (4) is damaged even when stored. Never.

With the above configuration, when the work is performed by using the work platform at night and the telescopic boom (4) is stored in the boom rest (7) after the work is completed, it is provided on the upper surface of the boom rest (7). The guide light (8) is turned on, the operating device (9) is operated to position the telescopic boom (4) above the boom rest (7), and the operator or turntable (3) on the workbench (6). ) The operator above grasps the turning position of the telescopic boom (4) by looking at the position of the light of the guide light (8) that hits the lower surface of the telescopic boom (4), and guides the light that hits the lower surface of the telescopic boom (4). When the light of (8) is shifted to the left, it is swung to the right, and when it is shifted to the right, it is swung to the left, and the telescopic boom (4) is positioned right above the boom rest (7) to raise and lower. Telescopic boom (4) by retracting the cylinder (5) and lowering the telescopic boom (4) And stores it in the boom rest (7).

(7) Effect of the Invention As described above, in the present invention, since the guide light is provided on the upper surface of the boom rest of the work vehicle, when the work vehicle is used at night and the boom is retracted after the work is completed, A boom retracting guide light for a work vehicle is provided that allows the position of the boom rest to be easily grasped, and the present invention is effective in improving workability and safety of the work vehicle.
