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.

(b) Prior art In conventional aerial work vehicles, when the gondola approaches the work surface, there is a risk of the gondola colliding with the work surface, and it is difficult to control the boom device. The gondola was stopped some distance away, and a worker inside the gondola was 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 damage to the vehicle body.

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

(d) Structure of the invention The present invention provides a boom device that can be raised and lowered on a vehicle body, and a gondola is provided at the tip of the boom device,
The present invention relates to an aerial work vehicle having a fall prevention device for work tools, etc., which is retractably provided on the wall surface of the gondola in the work direction, the top of which can be opened when expanded.

(e) Examples Examples will be described below with reference to the drawings.

1 is a vehicle body, and a boom device 2 is mounted on the vehicle body 1 so as to be able to swing 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.

Reference numeral 4 denotes a fall prevention device attached to the outer wall of the gondola 3. If a worker accidentally drops a work tool while working inside the gondola 3, the fall prevention device 4 will catch the work tool and keep it on the ground. This is to prevent it from falling.

The fall prevention device 4 fixes a board 5 to the outer wall surface of the gondola 3. A lower part of a swing plate 6 is supported by a shaft 7 at the bottom of the board 5, and the swing plate 6 swings forward about the shaft 7. I am able to move. Foldable seats 8, 8 are attached between both side ends of the base plate 5 and the rocking plate 6, and when the rocking plate 6 is rocked forward, the base plate 5, the rocking plate 6, and the pair of sheets are attached. 8,
8 is shaped like a bag and has an opening 9 formed above, and the opening 9 connects the gondola 3 and the work surface 1.
It is designed so that it can be opened to the same extent as the gap H between 0 and 0.

Reference numeral 11 denotes a lashing piece, and the lashing piece 11 is used to secure the swing plate 6 to the gondola 3 by sandwiching the swing plate 6 and a part of the gondola 3 when the swing plate 6 is stored.

A rope 12 is stretched between the swing plate 6 and the gondola 3, and the rope 12 is used to pull the swing plate 6 toward the gondola 3 when the swing plate 6 is stored.

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. Next, the operation will be explained. First, the vehicle body 1 is stopped at a work place,
The gondola 3 rotates or raises the boom device 2.
is brought closer to the work surface 10.

After the gondola 3 has stopped, the securing piece 11 fixing the rocking plate 6 is removed and the rocking plate 6 is pushed forward to form a bag with an opening 9 formed at the top as shown in FIG. Further rotation of the swing plate 6 is restricted by the rope 12.

After forming the opening 9, the operator opens the work surface 1.
Even if the worker starts work at 0 and 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 the rocking plate 6 toward the gondola 3 side, and the rocking plate 6
to the stored state. In this state, the securing piece 11 is fitted between the gondola 3 and the rocking plate 6 as shown in FIG. 2, and the rocking plate 6 is fixed in the retracted state.

(f) Effect of the Invention As described above, the present invention provides a fall prevention device on the gondola to catch work tools, etc. accidentally dropped by a worker, and prevents them from falling to the ground, thereby eliminating the possibility of injuring passersby as in the case of the conventional method. , there is no risk of 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, 4
is a fall prevention device.

Claims (1)

[Claims] 1 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 bag-shaped work tool that can be opened at the top when expanded is provided on the wall surface of the gondola in the working direction. An aerial work vehicle equipped with a retractable fall prevention device for work tools, etc.
