Description

[Detailed description of the invention] (1) Industrial application field The present invention is a cargo platform rain protection device for a cargo transport vehicle in which a cargo platform carrying cargo moves up and down along a ladder and slides forward at the tip of the ladder. It is related to.

(2) Prior Art A load carrying work vehicle in which a load carrying load moves up and down along a ladder and also slides forward at the tip of the ladder is described, for example, in Japanese Patent Application Laid-Open No. 59-48378. has been known from the past.

(3) Problems that the invention aims to solve However, since conventional load-carrying work vehicles do not have a rain protection device on the loading platform to prevent rain, etc., it is difficult to use the load-carrying work vehicle to lift and lower goods in rainy weather. If you do this, there is a problem that the cargo on the loading platform will get wet.To solve this problem, installing a cover such as a top plate on the loading platform will make it easier to load and unload cargo at the tip of the ladder. There is a problem in that when the loading platform is slid forward, the cover comes into contact with a building wall or the like and is damaged.

(4) Means for Solving the Problems In order to solve the above problems, the present invention provides a loading platform that can move up and down along the top surface of a multi-stage telescoping ladder and can also slide forward at the tip of the multi-stage telescoping ladder. This is a load carrying work vehicle equipped with a rain protection device that is slidable in the front and rear directions of the loading platform.

(5) Effect With the above configuration, when the loading platform is moved up and down along the multi-tiered telescoping ladder, the rain shield device is kept sliding forward to cover the loading platform, and cargo, etc. can be loaded and unloaded at the tip of the ladder. When the loading platform is slid forward at the tip of a multi-tiered telescoping ladder, the rain protection device comes into contact with the wall of the building, and when the loading platform is further slid forward in this state, the rain protection device slides backward. do.

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

Figure 2 shows a load carrying work vehicle, with outrigger 2
A turntable 3 is rotatably provided on the vehicle body 1 supported by a turntable 3, a base end of a multi-stage telescoping ladder 4 is pivotally supported on the turntable 3, and the other end of the telescoping ladder 4 is supported by a turntable 3.
is expanded and contracted by a telescoping device (not shown) and raised and lowered by an undulating cylinder 6. A cart 7 is attached to the top surface of the multi-stage telescoping ladder 4 so as to move up and down along the multi-stage telescoping ladder 4. One end of the support base 8 is pivotally supported for free swinging, and the support base 8 is always maintained in equilibrium by a balance maintaining device 9 installed between the support base 8 and the trolley 7, regardless of the up-and-down angle of the multi-stage telescoping ladder 4. A loading platform 5 is attached to the upper surface of the vehicle 8 so as to be slidable forward, and a rain prevention device 24 is detachably attached to the loading platform 5.

As shown in FIG. 1, the loading platform 5 has four sides 52, 53, 5 on the front, rear, left and right sides of a bottom surface 51 on which luggage is placed.
4 and 55, and a front side 52, a left side 54, and a right side 55 are attached to the bottom 51 so as to be able to swing outward between a vertical position and a horizontal position, respectively.

The rain protection device 24 is provided with a pair of support holes 10 and 11 vertically at the upper end of the rear side surface 53, into which the base ends of the pair of support columns 12 and 13 are inserted, and between the support holes 12 and 13. are connected by a support rod 14, and cylindrical support pieces 15, 16 are attached to the upper ends of each support column 12, 13 approximately horizontally in the front and rear directions, respectively. Each support piece 15, 16 has a support piece 15, 1
Frame pieces 17 and 18 longer than 6 are slidably inserted, and the front and rear sides of a square frame 19 are attached to both ends of each frame piece 17 and 18. In addition to the frame pieces 17 and 18, they are connected by a support rod 20. Each frame piece 17, 18 has each support piece 15,
16 and the rear side of the frame 19, the springs 22 and 23 are biased to protrude forward relative to the support pieces 15 and 16, respectively, and the frame 19, each frame piece 17 and 18, and each support Piece 1
5, 16 and the support rod 20 are covered with a sheet 21.

With the above configuration, when working with the rain protection device 24 attached to the loading platform 5, the base ends of the columns 12 and 13 are inserted into the support holes 10 and 11, and the rain protection device 24 is attached to the loading platform 5.
is attached to the loading platform 5, the multi-stage telescoping ladder 4 is set at the working position, and the cart 7 is moved up and down along the multi-stage telescoping ladder 4, as shown in FIG. Next, when the loading platform 5 is slid forward with respect to the support platform 8 in order to load and unload cargo at the tip of the multi-stage telescoping ladder 4, the front side of the frame 19 of the rain protection device 24 is moved by the sliding movement of the loading platform 5. When the loading platform 5 is further slid forward in this state, the frame pieces 17 and 1
8 slides rearward against the urging force of springs 22 and 23, and moves the rain protection device 24 rearward. After loading and unloading the cargo, when the loading platform 5 is slid rearward, the frame pieces 17 and 18 slide forward due to the biasing forces of the springs 22 and 23, moving the rain protection device 24 forward and moving the loading platform 5. cover. In addition, when the rain protection device 24 is not used, the pillar 12,
13 and remove the rain protection device 24 from the loading platform 5.

In addition, in the above embodiment, the rain protection device 24
The pillars 12 and 13 are attached to the rear side of the loading platform 5, but if you want to make the four sides of the loading platform 5 freely openable and closable, as shown in FIG. Attach brackets 26 and 27 to
By detachably inserting the support columns 12 and 13 of the rain protection device 24 into the respective brackets 26 and 27, the four sides of the loading platform 5 can be made openable and closable.

(7) Effects of the invention As described above, according to the present invention, the rain protection device attached to the loading platform is provided so as to be slidable in the front and rear directions, so the loading platform can be slid without damaging the rain protection device. The present invention is effective in improving the efficiency of cargo transportation work.
