(57) [Abstract] [Purpose] To provide an aerial work vehicle at a low cost with a simple structure and capable of expanding the work area as needed. [Structure] An extension floor 5 is connected to one side of a workbench 3 so as to be vertically rotatable.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an aerial work vehicle used for ceiling work or the like at a construction site, and more particularly to an aerial work vehicle in which an extended floor is connected to a work table in order to increase a work area.

[0002]

[Prior art]

 Generally, work platforms of aerial work platforms have poor workability because the size of the workbench is limited. For this reason, some work floors are attached to the side of the workbench to expand the work area and improve workability. This extension floor was attached to one side of the workbench with a mounting pin, or was stored under the workbench and was attached so as to project from the workbench by a power mechanism.

[0003]

[Problems to be solved by the device]

 However, in the case where the above-mentioned mounting pin is used to mount the extended floor, it takes time and effort to mount it, and the extended floor is a separate entity from the aerial work vehicle, so a storage place for the extended floor was required.

Further, in the structure in which the extension floor is projected from the workbench by the power mechanism, the mechanism is complicated and the manufacturing cost of the aerial work vehicle is increased.

Therefore, the present invention has an object to provide an aerial work vehicle that has a simple structure and can expand the work area as needed at a low cost.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides an elevation work machine, in which an elevating mechanism is provided between a base and a work table, and the work table is elevated by the elevating mechanism. The expansion floor is connected so as to be vertically rotatable.

[0007]

[Action]

 As a result, when transporting or traveling an aerial work vehicle, the extended floor should be rotated 90 degrees upward with the attachment part to the work table as a fulcrum and held vertically on one side of the work table. You can Further, when using the extended floor, the extended floor can be rotated 90 degrees downward from the above-mentioned state with the attachment portion to the workbench as a fulcrum to project from the workbench.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The aerial work vehicle 1 has a scissor link mechanism 4 as an elevating mechanism arranged between a movable base 2 and a work table 3. By opening and closing the scissor link mechanism 4, The workbench 3 is raised and lowered. Further, an extension floor 5 is connected to one side of the workbench 3 so as to be vertically rotatable about a connecting portion with the workbench 3 as a fulcrum.

The workbench 3 is formed in a rectangular shape having substantially the same area as the upper surface of the base 2, and mounting portions 3a, 3a of the extension floor 5 are provided at both ends of one side. Each mounting portion 3a is formed by projecting two plate members in parallel with the width direction of the workbench 3, and a pin insertion hole is formed in the central portion of each plate member. Further, a handrail 7 is erected on the outer periphery of the workbench 3 excluding the extension floor connection side, and a receiving portion 3b of the extension floor 5 and a stopper 3c are provided on the upper surface of the workbench 3 so as to project.

The extension floor 5 is formed in a rectangular shape having a width narrower than that of the workbench 3, and mounting arms 5a, 5a for mounting the workbench are projectingly provided on one side thereof. Further, each mounting arm 5a is provided with a pin insertion hole that communicates with the pin insertion hole of the mounting portion 3a. The workbench 3 and the extension floor 5 are rotatably connected in the vertical direction by holding the mounting arm 5a between the mounting portions 3a and inserting the pin 6 into the pin insertion hole.

A handrail 7 is erected on the outer periphery of the extension floor 5 excluding the workbench attachment side, similarly to the workbench 3, and a handrail 7a attached to the tip side has an extension floor with one end as a fulcrum. It is attached to the inside of 5 so as to be rotatable by 90 degrees. Further, an air damper 8 is provided below the extension floor 5. This air damper 8 has one end attached to the end on the extension floor connecting side of the workbench 3 and the other end attached to the bottom on the tip side of the extension floor 5, so that the operator can easily rotate the extension floor 5 in the vertical direction. I am able to do it.

In the aerial work vehicle 1 as described above, the extended floor 5 is pivoted 90 degrees in the vertical direction about the mounting portions 3a, 3a as a fulcrum during transportation or traveling, and the extended floor 5 is mounted on one side of the workbench 3. Hold vertically. At this time, the handrail 7 on the side of the extension floor 5 is brought into contact with the receiving portions 3b 1 and 3b of the workbench 3 and fixed to the workbench 3 by the stoppers 3c and 3c. Further, the handrail 7a on the front end side is rotated 90 degrees about one end as a fulcrum, and is overlapped with the handrail 7 on the side. Further, when it is desired to extend the work area of the workbench 3, the stoppers 3c, 3c are removed from the handrail 7, and the extension floor 5 is rotated around the mounting portions 3a, 3a as a fulcrum so that the workbench 3 can be extended horizontally. The handrail 7a on the tip side of the floor 5 is rotated and attached at a predetermined position. Further, when the horizontally extended extension floor 6 is erected vertically on the workbench 3, the operator can easily lift the extension floor 5 by the air damper 8 provided at the bottom of the extension floor 5.

As described above, by mounting the extension floor 5 on the workbench 3 so as to be rotatable in the vertical direction, the work area of the workbench 3 can be adjusted as needed without causing any support for transportation or traveling. Can be extended. Further, since the extension floor 5 is stored in the workbench 3, no extra space is required and the extension floor 5 can be easily extended and stored. Furthermore, since the extension floor 5 can be connected to the workbench 3 with a simple structure, the manufacturing cost of the aerial work vehicle 1 does not increase.

In the above embodiment, the scissors link mechanism is opened and closed as the elevating mechanism. However, the elevating mechanism is not limited to this, and a vertical mast system or a bending or telescopic arm system is used. It may be a mechanism.

[0015]

As described above, according to the present invention, since the extension floor is vertically rotatably connected to one side of the workbench, the extension floor can be attached to the workbench with a simple structure. . In addition, the extended floor can be easily extended and stowed, the work area can be expanded as necessary, and there is no risk that the extended floor will support the transportation or traveling of the aerial work vehicle. Further, the simple structure makes it possible to provide it at low cost.
