Description

[Detailed Description of the Invention] This invention relates to a storage structure for a stick used to reliably hold the loading platform in a raised state in a power transport vehicle having a loading platform that can be freely dumped.

For power transport vehicles equipped with a dump-type loading platform, the loading platform is often raised when inspecting or servicing the vehicle body, but at this time there is a space between the loading platform frame and the vehicle body frame to prevent the loading platform from lowering due to an unexpected accident. A stick is interposed to ensure that this raised state is maintained. However, in the past, the cane was stored next to the driver's seat because it was not appropriate, but this method has disadvantages such as inconvenience in handling the cane.

Therefore, in the present invention, the stick can be taken out immediately when it is used, and the stick can be reliably stored while having a simple structure.

The present invention will be explained below based on embodiments shown in the drawings.

A has three running wheels 1 and 2 on each side of the vehicle body a,
It is a six-wheel power transport vehicle equipped with a drive unit 6 provided at the rear of the vehicle body a, which receives power from an engine 4 provided at the front of the vehicle body a via a propeller shaft 5.
while transmitting power from the traveling drive unit 6 to the left and right traveling drive chain devices 7, 7, respectively, and driving the left and right traveling wheels 1, 2, 3 by the chain devices 7, 7. The vehicle body a is configured to run.

Reference numeral 8 denotes a loading platform provided at the rear of the vehicle body a for dumping, and a chain case 7' serving as the vehicle body frame a'.
An upward bracket 9 is erected at the rear end, and a downward bracket 10 is protruded from the rear end of the platform frame 8', and both brackets 9 and 10 are connected by a pivot pin 11, and the cylinder body 12a is connected by a pivot pin 11. The base end is pivotally attached 13 to the horizontal frame 7'' which is passed between the front ends of the chain cases 7', 7', and the tip of the rod 12b is attached to the horizontal frame 7'' which is passed between the middle parts of the carrier frames 8', 8'. A hydraulic cylinder 12 for raising and lowering the loading platform is provided which is pivotally connected to the frame 8'', and the loading platform 8 is configured to be raised and lowered around a pivot point at the base end as the hydraulic cylinder 12 expands and contracts. There is.

Reference numeral 15 denotes a stick that is interposed between the cargo platform frame 8' and the chain case 7' serving as the vehicle body frame a' to reliably maintain the elevated state of the cargo platform 8 when the cargo platform 8 is in the elevated state; Support rod 15a
It has a structure in which L-shaped members 15b, 15b are respectively welded to both ends of. Furthermore, both L-shaped members 15
b, 15b are provided with their opening sides facing in the same direction, and their receiving surfaces 15b', 15
b' is inclined at a slight angle from the direction perpendicular to the length direction of the support rod 15a. This allows the stick 15 to be attached from one side of the frames 7', 8', and when the stick 15 is attached, the receiving surfaces 15b', 15b' of the L-shaped members 15b, 15b,
The vertical plate portions 15b'', 15b'' fit into the rectangular cross-section of the vehicle body and the right-angled corners of the cargo platform frames a', 8', respectively. This is the structure for this purpose.

16, 16 is the support rod 1 in the above-mentioned stick 15
These are through holes formed in the same direction at both ends of the stick 5a, and support rods 17, 17 are provided upright in the chain case 7' where the stick 15 is interposed. In this case, the support rods 17, 17 are formed into approximately L-shaped rods with horizontally facing parts 17', 17' provided at their base ends, respectively, and the tips of the horizontally facing parts 17', 17' are connected to the sides of the chain case 7'. By welding it to the chain case 7', it is erected with a slight gap t maintained between it and the side surface of the chain case 7'.

Further, 18 and 18 are inserted into the stick 15 by passing the support rods 17 and 17 through the through holes 16 and 16, respectively.
is stored along the chain case 7', the support rods 17, exposed from the through holes 16, 16,
This is a snap pin that is fixed to the penetrating tip of 17 to fix the retracted state of the stick 15, and 19 and 19 are the same snap pins 18 and 18.
This is a pin hole for use.

Therefore, this cane 15 is stored at the place where it is used, that is, at a place interposed between the frames 7 and 8, and its storage structure is such that the through hole 1
6 through the support rod 17 and the snap pin 18
It has an extremely simple structure in which it is fixed.

The stick 15 is interposed between the frames 7' and 8' when the loading platform 8 is in the raised state to maintain the raised condition of the loading platform 8. In this case, the support rod 1
When the stick 15 is installed while intervening the vertical plate part 15b'' of the L-shaped member 15b in the gap t formed by the horizontal part 17' of the stick 15, the stick 15
The skidding is caught by the support rod 17,
The attached state of the stick 15 is ensured.

As mentioned above, according to the present proposal, the cane is stored in the place where it is used, so it can be removed immediately when it is used, and it can be stored immediately after use without worrying that it has been left behind. This has the effect of making it extremely easy to handle. In addition, although the structure is simple, it can be reliably stored, and the stick 15 is prevented from skidding, improving safety.
By supporting the right angle corner of a' and distributing the same load, there is also the effect that no extra reinforcement is required for the vehicle body frame a'.
