Description

[Detailed description of the invention] (1) Industrial application field The present invention relates to a work platform device for an aerial work vehicle, and is particularly suitable for communication work such as optical cables.

(2) Prior Art It is conventionally known to cover the upper part of the workbench of an aerial work vehicle with a tent, as described in, for example, Japanese Utility Model Application Publication No. 59-185352.

(3) Problems that the invention aims to solve However, in the conventional work platform devices for aerial work vehicles, the struts supporting the tent were formed in a straight line, making it difficult to connect cables inside the tent. In this method, the cable had to be bent into a U-shape, which resulted in the risk of damaging the cable and poor workability.

(4) Means for Solving the Problems In order to solve the above problems, the present invention has developed an aerial work vehicle that has side surfaces on the front, rear, left and right sides of the bottom and whose upper part is covered with a tent supported by a frame. In the workbench, a support part for supporting the shelf board is provided on the inner periphery of the side surface, and the pillars of the frame located on the left and right sides of the support part are formed in the shape of a crank with a recessed base end.

(5) Effect With the above configuration, by positioning the cable at the retracted base end of the crank-shaped support, the cable is pulled into the tent and placed on the shelf board placed on the support. Connect the cables that have been brought in.

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

As shown in FIG. 3, in the aerial work vehicle, a turntable 2 is rotatably provided on a vehicle body 1, a base end of a lower boom 3 is pivotally supported on the turntable 2, and an uplift boom 4 is attached to the tip of the lower boom 3. The lower boom 3 is raised and lowered by an undulating cylinder 6, and the upper boom 4 is bent and extended by a bending cylinder 7. A workbench 5 is held in balance at the tip of the upperboom 4, and the upper part of the workbench 5 is covered by a tent 8. ing.

The workbench 5, as shown in FIGS. 1 and 2,
The bottom surface 51 on which the worker is mounted is surrounded by four side surfaces 52, 53, 54, and 55 on the front, rear, left, and right sides.
The workbench 5 is attached to the tip of the upper boom 4 on the rear side 53, and a support part 56 for supporting the shelf board 9 is formed in the middle of the inner periphery of the front side 52, left side 54, and right side 55 in the shape of a brim. and the support part 5
By placing the shelf board 9 on the collar of 6, the shelf board 9 becomes a table.

A pair of support holes 57 and 58 are vertically provided at the upper ends of the inner peripheries of the left side surface 54 and the right side surface 55, respectively, into which the base of a frame that supports the tent is inserted. The base ends of a pair of crank-shaped struts 81 and straight struts 82 are inserted, frame pieces 83 are horizontally attached to the upper ends of each strut 81 and strut 82, and three frame pieces 83 are installed between the two frame pieces 83. The frames are connected by frame pieces 84 to form a frame, and the tent 8 is formed by covering the upper surface of the frame and the front, rear, left and right sides with sheets 85.

With the above configuration, when connecting optical cables, etc., with the tent 8 attached to the workbench 5, the workbench 5 is connected to the cable 10 by rotating the turntable 2, raising and lowering the lower boom 3, and bending and extending the upper boom 4. As shown in FIGS. 4 and 5, open the fastener 86 provided on the side surface of the seat 85 and place it in the retracted position at the base of the support column 81, parallel to the front surface 52 of the workbench 5. cable 10
is pulled in, and the cable 10 is connected using a connector on the shelf board 9. After the connection work is completed, the workbench 5 is moved and the cable 10 is taken out of the tent 8.

Also, by removing the tent 8 and shelf board 9,
It can also be used as a regular workbench.

(7) Effects of the invention As described above, according to the invention, by positioning the cable at the retracted base end of the crank-shaped support, the cable can be straightened without being bent into a U-shape. Since work can be performed on the shelf board in the tent while the cable is maintained in the same state, there is provided a work platform device for an aerial work vehicle that not only does not have the risk of damaging the cable but also has excellent workability.
