Description

[Detailed Description of the Invention] (1) Field of Industrial Application The present invention relates to a ladder loading device for a working vehicle, in which a ladder is detachably attached to a tool box provided on the vehicle body.

(2) Conventional technology It has been known for a long time that a work vehicle used for electrical work, etc. is equipped with a boom and a tool box on the vehicle body for storing tools, etc., and that a ladder for working at heights is loaded on the top of the tool box. It was getting worse.

(3) Problems that the invention aims to solve However, conventional ladders were fixed by a fixing device attached to the top of the tool box, so when operating the boom during work, it was necessary to prevent interference between the boom and the ladder. In order to prevent this, the ladder must be lowered, which makes the work complicated.Furthermore, since the ladder is loaded at a high position, it takes time to unload the ladder.

(4) Means for solving the problems In order to solve the above problems, the present invention provides a work vehicle equipped with a boom and a tool box on the vehicle body.
A pair of guide rails are attached to the top of the tool box facing the left and right directions of the vehicle body, a slide rail that slides outward from the vehicle body along these guide rails, and a ladder that is attached to the slide rails and supports the ladder in a removable manner. The ladder support device includes a ladder support device and a fixing device that is attached to the guide rail and fixes the ladder support device to the guide rail.

(5) Effect With the above configuration, the ladder support device is moved by sliding the slide rail along the guide rail to operate the boom or unload the ladder, so there is no possibility of interference between the working device and the ladder. This makes it easy to load and unload the ladder.

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

As shown in Figures 3 and 4, the aerial work vehicle is
A turntable 3 is rotatably placed on the vehicle body 1 supported by outriggers 2, and the base end of a telescoping boom 4 is pivotally supported on the turntable 3. ), and is also raised and lowered by the extension and contraction of the undulation cylinder 5, and a workbench 6 is held in equilibrium at the tip of the telescoping boom 4. Tool boxes 7 and 8 for storing tools and the like are attached to the left and right sides of the turntable 3 placed on the vehicle body 1, respectively, and a ladder loading device 9 for loading a ladder 16 is attached to the upper surface of the tool box 8 on the right side. It is being

As shown in FIGS. 1 and 2, the ladder loading device 9 has a pair of guide rails 10 attached to the upper surface of the tool box 8 in parallel in the left-right direction of the tool box 8. Guide rail 1
Slide rails 11 are slidably attached to the outside of the tool box 8 along 0, and ladder holders 12 and 13 on which a ladder 16 is placed above are respectively attached to these slide rails 11, and these ladder holders 12, 13 has a ladder 16 with a ladder support 1
Fixing rod 1 to prevent it from falling from 2, 13
5 are installed respectively. Both ladder receivers 12 and 13 are connected by a connecting rod 14, and the guide rail 10 has guides for the ladder receivers 12 and 13 in a position where they protrude outside the tool box 8 and a position where they are stored on the tool box 8, respectively. Fixing pins 17 to be fixed to the rails 10 are respectively attached, and the ladder receivers 1
2, 13, the connecting rod 14 and the fixing rod 15 constitute a ladder support device. The ladder supports 12 and 13 hold the ladder 16 at an angle, so that the ladder support 12 located at the front of the tool box 8 is higher than the ladder support 13 located at the rear of the tool box 8.

With the above configuration, when performing work at height using an aerial work vehicle or loading and unloading a ladder, the fixation of the ladder receivers 12 and 13 by the fixing pin 17 is released, and the slide rail 11 by sliding them along the guide rails 10 to the outside of the tool box 8, the ladder receivers 12 and 13 protrude outside the tool box 8, and in this state, the fixing pin 17
By fixing the ladder receivers 12 and 13 to the guide rail 10, the ladder receivers 12 and 13 protrude outward from the tool box 8 and are fixed. Ladder 16 and telescopic boom 4 placed on 12 and 13
The ladder 16 can be easily loaded and unloaded onto the ladder receivers 12 and 13 without interfering with each other. In addition, when traveling the aerial work vehicle, etc., the ladder receivers 12 and 13 fixed to the outside of the tool box 8 are released from the fixing pins 17, and the slide rails 11 are attached to the guide rails 10, respectively. The ladder receivers 12 and 13 are stored on the tool box 8 by sliding them onto the tool box 8 along the same line, and in this state, the ladder receivers 12 and 13 are fixed to the guide rail 10 with the fixing pin 17. stored above.

(7) Effects of the invention As described above, the present invention allows the ladder support device that supports the ladder to slide freely between the top surface of the tool box and the position protruding outward from the tool box. Provided is a ladder loading device for a work vehicle that can prevent interference between a ladder and a boom by sliding a support device outside a tool box, and can also easily load and unload a ladder.
The present invention is effective in improving the work efficiency of work vehicles.
