Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention is used in the field of aerial work vehicles in which workers work inside gondolas.

(bl Prior Art) With conventional aerial work vehicles, there is a risk of the gondola colliding with the work surface when the gondola approaches the work surface, and it is difficult to control the boom device. After some effort, the gondola was stopped, and the workers inside the gondola were leaning over and working on the work surface.

As a result, a gap is created between the work surface and the gondola, and workers may accidentally drop work tools (e.g. spanners, adjustable wrenches) onto the ground through the gap, causing injury to passersby. , there was a risk of damaging the vehicle body.

(C) Purpose of the Invention The purpose of the present invention is to eliminate the above-mentioned drawbacks, and the purpose of the present invention is to prevent tools from falling to the ground even if a worker accidentally drops them while working inside a gondola. This is what I did.

(dl Structure of the Invention The present invention provides a boom device that can be raised and lowered on a vehicle body, a gondola is provided at the tip of the boom device, and a work tool or the like that can open upwardly when expanded is provided on the wall surface of the gondola in the working direction. The present invention relates to an aerial work vehicle having a fall prevention device for work tools, etc., which is provided with a fall prevention device that can be stored.

(el example Examples will be described below with reference to the drawings.

(1) is the car body, and on the car body (11 is a boom device (2)
is equipped with the ability to swivel and raise and lower.

A gondola (3) is provided at the tip of the boom device (2), and a worker can work inside the gondola (3).

(4) is a fall prevention device attached to the outer wall of gondola (3), and this fall prevention device (4) is used to prevent workers from accidentally dropping work tools while working inside gondola (3). This is to catch the work tools and prevent them from falling to the ground.

The fall prevention device (4) moves the board (5) to the gondola (3).
It is fixed to the outer wall surface, and a swing plate (6) is installed at the bottom of the board (5).
) is supported by a shaft (7), and the rocking plate (6) is supported by a shaft (7).
) so that it can swing forward.

A foldable seat (8) +81 is attached between both side ends of the base plate (5) and the swing plate (6), and
6) when rocking forward, the substrate (5) and the rocking plate (
6) and a pair of sheets f81+81 are shaped like a bag and form an opening (9) at the top, and the opening (9)
9) can be opened to the same extent as the gap H between the gondola (3) and the work surface α0).

(11) is a lashing piece, and the lashing piece (11) holds the rocking plate (6) between the rocking plate (6) and a part of the gondola (3) when the rocking plate (6) is stored. (3) This is for fixing to.

(12) is a rope passed between the rocking plate (6) and the gondola (3), and the rope (12) is attached to the rocking plate (6) when the rocking plate (6) is stored. This is to draw the people towards the gondola (3).

It should be noted that the fall prevention device is not limited to the structure as in the embodiment, but can have a similar function and effect as long as it has a bag-like opening when expanded and can receive work tools, etc. It is.

The present invention has the above-mentioned configuration, and its operation will be explained next. First, the vehicle body (1) is stopped at a work place, and the boom device (2) is rotated or raised to bring the gondola (3) closer to the work surface QO).

After the gondola (3) has stopped, remove the lashing piece (11) that fixes the rocking plate (6) and push the rocking plate (6) forward to open the opening at the top as shown in Figure 3. (9), and further rotation of the rocking plate (6) is restricted by the rope (12).

After forming the opening (9), the operator moves to the work surface 00)
Even if a worker accidentally drops a work tool during work, the work tool is caught by a fall prevention device (4) and prevented from falling to the ground.

Next, when the work is completed, pull the rope (12) and swing it toward the gondola (3) side of the swing plate (6).
) to the stored state. In that state, the lashing piece (
11) is fitted between the gondola (3) and the swing plate (6), and the swing plate (6) is fixed in the retracted state.

(fl) More than the effects of the invention (The present invention is equipped with a fall prevention device on the gondola to catch work tools, etc. accidentally dropped by workers, and prevent them from falling to the ground. There is no danger of falling over or damaging the vehicle, and workers can work with peace of mind.

[Brief explanation of drawings]

FIG. 1 is an overall view of the present invention, FIG. 2 is an enlarged view of the main parts, and FIG. 3 is an operating state diagram. (1) is the vehicle body, (2) is the boom device, (3) is the gondola, and (4) is the fall prevention device. Applicant: Kyokuto Kaihatsu Kogyo Co., Ltd.

Claims (1)

[Claims] A boom device that can be raised and lowered is provided on the vehicle body, a gondola is provided at the tip of the boom device, and a fall prevention device such as a work tool that can be opened upward when expanded is provided on a wall surface of the gondola in the working direction so that it can be stored. An aerial work vehicle equipped with a fall prevention device for work tools, etc.
