Description

[Detailed description of the invention] The present invention relates to a structure that includes measures to ensure safety when operating the lifting/lowering platform in a lifter vehicle in which the lifting/lowering loading platform and the operating section are arranged adjacent to each other on the chassis. .

In conventional lift vehicles, when the loading platform is raised above the height of the operating section, a vertical space is created between the operating section and the loading platform, and if an item enters this vertical space, the loading platform may be There were cases where items were damaged when being lowered. In particular, if a worker carelessly inserts his or her hand into the vertical space, there is a risk of causing a serious accident.

The present invention was created with the purpose of eliminating the drawbacks of the conventional lifter vehicle as described above.
The gist of this is that in a lifter vehicle in which an operating section and a loading platform are installed adjacently and juxtaposed on the chassis, and the loading platform can be raised and lowered from the top surface of the chassis to a position higher than the operating section, the operating section A vertically movable plate-shaped safety cover is installed between the platform and the platform, and when the platform rises, a part of the platform hooks the locking part provided on the safety cover, and the safety cover The main feature is that it moves up and down as the loading platform moves up and down.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A safety lifter vehicle according to the present invention (hereinafter referred to as the present invention lifter vehicle) will be explained below based on drawings showing embodiments thereof.

Figure 1 shows how to transfer goods loaded onto a loading platform.
2 is a side view of the proposed lifter vehicle located near a large truck, and FIG. 2 is a front view of the proposed lifter vehicle in FIG. 1 from the right side. As shown in FIGS. 1 and 2, the lifter vehicle according to the present invention has an operating section 1
and a loading platform 2 are installed on the vehicle platform 11 in a juxtaposed state. The loading platform 1 is supported by a lifting cross link 9 in order to facilitate the transfer of loaded articles between a high place and a low place. cross link 9
Although the lifting and lowering is performed by a known cylinder, illustration of the cylinder is omitted to avoid complication. When the cross link 9 is driven to raise the loading platform 2 to the position indicated by the dashed line, a vertical space X is created between the operating section 1 and the loading platform 2. Conventionally, there was a danger if an object entered the vertical space X or if a worker carelessly inserted his hand in an attempt to remove an object that had entered. Therefore, the lifter vehicle of the present invention has a structure in which when the loading platform 2 is raised, this vertical space X is automatically cut off between the operating section 1 side and the loading platform 2 side. Automatic shutoff in this case was performed by a plate-shaped safety cover 3 that moves up and down as the loading platform 2 moves up and down.

The safety cover 3 is interposed between the operating portion 1 and the loading platform 2, and is erected so as to be vertically movable. A vertically movable state of the safety cover 3 is ensured by a guide member 5 erected along the back wall 1a of the operating section 1. That is, as is clear from FIG. 3, which is a cross-sectional view taken along the line 1 in FIG. The ribs are fixed and erected so as to face each other, and a guide groove is formed between the rib of the L-shaped rigid frame and the back wall 1a of the operating section 1, and the safety cover 3 is loosely fitted into this guide groove. . The safety cover 3 has a plate shape, as seen in an enlarged perspective view of FIG.
A locking portion 4 is biased along its upper edge. The locking part 4 was held against it by holding an angle member. The locking portion 4 protrudes toward the loading platform 2, and is caught on a portion of the upper edge of the loading platform 2 when the loading platform 2 rises from the top surface of the vehicle platform 11. Therefore, the safety cover 3 is lifted upward as the loading platform 2 rises. For this reason,
The vertical space X created by the lifting of the loading platform 2 is automatically cut off between the operating section 1 side and the loading platform 2 side by the lifted safety cover 3. A scale 6 indicating the upward mobility is attached to the safety cover 3 in the vertical direction, and the upward mobility of the safety cover 3 and the loading platform 2 can be determined by the indication of the indicator needle 7. When the loading platform 2 is lowered, the safety cover 3 also moves downward, and the lower edge of the safety cover 3 comes into contact with the upper surface of the vehicle platform 11 and stops. At this time, the vertical space X between the operating section 1 and the loading platform 2 is eliminated. In this embodiment, the width of the safety cover 3 is approximately the same as the width of the operating section 1, but it may be the same as the width of the loading platform 2. Although steel is most commonly used as the material for forming the safety cover 3 and the locking portion 4, plastic or wood may also be used. FIG. 5 is an enlarged perspective view showing a safety cover 3' according to another embodiment. This safety cover 3' has a frame material around the periphery, and a net material 3a is stretched over a wide central area. By doing so, the raised state of the loading platform 2 can be seen through the net material 3a. Furthermore, the locking portion 4' is simplified by being attached to the end of the upper edge of the safety cover 3'.

1 and 2, 81 is an operating lever for raising and lowering the cargo platform 2, 82 is a steering lever for driving, 83 is a clutch lever for driving and stopping, 84 is a gear shift lever for changing the driving gear,
10 is a caterpillar of the proposed lifter vehicle, 12 is a rear part of a large truck that is intended to transfer articles from the proposed lifter vehicle, and 13 is a loading platform of the large truck 12.

Next, the operation of the lifter vehicle according to the present invention will be explained. By operating the operating lever 81 of the operating section 1, the loading platform 2 is raised to the height of the loading platform 13 of the large truck 12. At that time, part of the upper edge of the loading platform 2 is covered by the safety cover 3.
Hook the locking part 4 and lift the safety cover 3. Therefore, the vertical space X generated between the operating section 1 and the loading platform 2 is completely blocked off by the safety cover 3 between the operating section 1 side and the loading platform 2 side. Of course, the height of the safety cover 3 is such that it does not slip out of the guide member 5 due to its upward movement. Due to this blocking, articles do not enter the vertical space X, and there is no risk of an operator inserting a part of the human body such as a hand.
Whether or not the loading platform 2 has been raised to the height of the loading platform 13 of the large truck 12 can be determined by reading the scale 6 indicated by the indicator needle 7. In the case where the safety cover 3 has a net material stretched over the central area, the rising height of the loading platform 3 can also be confirmed by seeing through the net material. After the articles loaded on the loading platform 2 are transferred to the loading platform 13 of the large truck 12, the loading platform 2 is lowered. Along with this, the safety cover 3 also moves downward. Therefore, the vertical space X created between the operating section 1 and the loading platform 2 remains cut off between the operating section 1 side and the loading platform 2 side until it is resolved by the lowering of the loading platform 2. There is no danger of objects getting into this vertical space X and being damaged, or of hands etc. being inserted and causing unexpected disasters.
Then, the loading platform 2 finishes descending to the upper surface of the original vehicle platform 11.

Since the proposed lifter vehicle is as described above, when carrying goods and transferring them between high and low places, it can be carried out safely without damaging the goods or injuring workers. In addition to being able to carry out work, the rising height of the loading platform can be confirmed by reading the scale attached to the safety cover or by seeing through the netting stretched over the safety cover, making it easy to check the height of the cargo platform. Transfer work can be performed easily and efficiently.
