DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerial work vehicle used for work on a ceiling or a wall at a construction site.

[0002]

2. Description of the Related Art An aerial work vehicle is provided with a worktable that can be raised and lowered on a traveling vehicle body in order to perform work on a ceiling or an upper wall of a construction site. Also, when working outside the pillars or outside the windows, attach the sub-deck with a T-shape in plan view to the workbench .
At the front end , the sub-deck protrudes outside the pillars and windows, so that the worker can work around the outside. In addition, in this specification, the front end is the front and rear
Means the front end side in the traveling direction of the working vehicle that can travel.

[0003]

However, in the above-described structure, work can be performed when the distance between adjacent columns or the opening of the window is wider than the width of the sub-deck, but the vehicle body is moved laterally each time. I had to let it. Also, if the distance between adjacent columns or the opening of the window is smaller than the width of the sub-deck, the sub-deck cannot be passed. Especially,
If the column stands outside the wall, the front end of the traveling body
The distance in plan view between the surface and the end surface of the sub deck on the traveling body side is short.
As a result, the front end surface of the traveling vehicle abuts against the inner surface of the wall,
The deck cannot go around the outer side of the pillar,
Business could not be done. In addition, it stands upright and left corner of the floor
Pillars cannot be handled without replacing the sub-deck
won.

[0004] Therefore, the present invention can pass through the work floor even when the distance between adjacent columns or the opening of the window is narrow, or when the columns are standing outside the wall. It is another object of the present invention to provide an aerial work vehicle in which a work floor can be located at an appropriate work place without moving a vehicle body in a lateral direction.

[0005]

The present invention for achieving the above object, there is provided a means for solving], in aerial work platforms provided to be vertically movable work platform to the vehicle body, the workbench of the front end, prior to the vehicle body <br A work floor protruding from the end surface is detachably provided, and an auxiliary floor is provided in the front half of the work floor so as to protrude from either the left or right end surface of the work floor by horizontal movement.

[0006]

[Work] According to the above configuration, the traveling vehicle is driven to pass the auxiliary floor between the pillars and the opening of the window, and after projecting the auxiliary floor outside the pillar and the outside of the window, the auxiliary floor is moved. Work can be performed by moving horizontally to the work place side and positioning it at an appropriate work place. An auxiliary floor is provided in the first half of the work floor.
So even if the pillars are standing outside the wall,
Distance between the front end face of the
It becomes longer, and the front end surface of the traveling body does not abut against the inner surface of the wall.
By moving the slab horizontally, it moves around the outer surface of the pillar.
Work on the outer side of the pillar.
Wear. In addition, the auxiliary floor is moved horizontally to the left and right of the work floor.
It can protrude from either end, so it can stand on the left or right corner of the floor.
The work floor and auxiliary floor are also exchanged for work on the pillars
Can be handled without replacement.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS.

[0008] Aerial 1, the upper portion of the vehicle body 2 via a scissors linkage 3 to the elevating supporting the worktable 4, the front end of the work table 4, projects from front end surface of the vehicle body 2 The work floor 5 is detachably provided, and is provided in front of the work floor .
The halves, left a wide auxiliary floor 6 of the vehicle body than the working floor 5
It is provided so that it can move horizontally to the right .

As shown in FIG. 3, the aerial work vehicle 1 constructed as described above moves the auxiliary floor 6 in the opposite direction (left side in the figure) to the column 7 serving as a work place, and
And the auxiliary floor 6 is passed between the column 7 and the adjacent column 8 to protrude outside the columns 7 and 8, and then the auxiliary floor 6 is placed on the side of the column 7 serving as a work place (right side in the figure). The worker moves horizontally to an appropriate work place, and a worker works outside the pillar 7.

Therefore, if the space between the pillars 7 and 8 is wider than the width of the auxiliary floor 6, the auxiliary floor 6 can pass through.
The auxiliary floor 6 can be protruded to the outside of the columns 7, 8 even at a smaller interval than before, and after the auxiliary floor 6 is protruded,
Since the auxiliary floor 6 is moved horizontally to the work place side, the traveling vehicle body 2 does not need to be moved in the lateral direction. In addition, the auxiliary floor 6
Since it is provided in the first half of the work floor 5, as shown in FIG.
Even if the pillars 7 and 8 are standing outside the wall,
A plan view of the front end face of the vehicle body 2 and the end face of the auxiliary floor 6 on the traveling vehicle body side
Becomes longer, and the front end face of the traveling vehicle body 2 hits the inner surface of the wall.
By moving the auxiliary floor 6 horizontally without touching it,
It can be turned around on the outer side, and works on the outer side
Work can be done. Further, the auxiliary floor 6 is
Project from either the left or right end of the floor.
Work floor 5 and auxiliary for work on pillars
It can be handled without changing the floor 6.

FIG. 4 shows a second embodiment of the present invention.
In the first half of the work floor 5, the horizontal
The auxiliary floor 10, which can protrude from the end face of the shift, is formed to have the same width as the work floor 5, and one side protrudes from the side of the work floor 5 by horizontal movement. Therefore, if the space between the columns 7 and 8 is wider than the width of the work floor 5 , the work floor 5 and the auxiliary floor 10 are replaced.
Without any pillars 7,8 auxiliary bed 10 by the horizontal movement
It can also be projected to the outside. Also, pillars 7 and 8
Even if you are standing on the outside of the wall, as in the first embodiment
In addition, the auxiliary floor 10 can be wrapped around the outer side of the pillar 8.
Wear.

[0012]

The present invention described above, according to the present invention is the workbench of the front end of the aerial work platforms, the working floor projecting from front end surface of the vehicle body together removably provided, the first half portion of said working bed,
An auxiliary floor that can protrude from either the left or right end face of the work floor by horizontal movement is provided, so that if the interval for projecting the work floor is wider than the width of the auxiliary floor, the auxiliary floor can pass through the auxiliary floor. Then, the auxiliary floor is horizontally moved to the work place side after the projecting, so that the traveling vehicle body does not need to be moved in the lateral direction. In particular, the auxiliary floor is provided in the first half of the work floor
So even if the pillars are standing outside the wall,
Distance between the front end face of the
It becomes longer, and the front end surface of the traveling body does not abut against the inner surface of the wall.
By moving the slab horizontally, it moves around the outer surface of the pillar.
Work on the outer side of the pillar.
Wear. In addition, the auxiliary floor is moved horizontally to the left and right of the work floor.
It can protrude from either end, so it can stand on the left or right corner of the floor.
The work floor and auxiliary floor are also exchanged for work on the pillars
Can be handled without replacement.
