Description

[Detailed Description of the Invention] This invention relates to a load carrying device,
In particular, the present invention relates to a transport vehicle that is used for transporting heavy objects at a steelworks, smelter, shipyard, etc., and is operated as a trackless means of transportation on the premises or on general roads. Some of these types of transport vehicles have a U-shaped trailer chassis connected to the rear of the towing part of the truck, and this trailer chassis can be used to carry various objects such as heavy objects, large-capacity objects, or long objects. There are devices equipped with various removable cargo holders such as containers and flat pallets according to the requirements of the vehicle, and the object of this invention is to propose a device for stably loading such cargo holders. It is.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the drawings shown as examples.

First, as shown in FIG.
It consists of 3 chassis. This trailer chassis 3 is provided with a U-shaped elevating part 4 on the inside, and as shown in FIG. is forming.

FIG. 2 shows a pallet 7 loaded with a coiled load 6, and FIG. 3 shows a container 9 loaded with a heavy load 8. The vehicle is transported by being placed on the elevating section 4 of the trailer chassis 3. In this case, the horizontal portion 5 supports the luggage rack from below. Furthermore, when loading or unloading the cargo tray on or off the lifting section 4, the lifting section 4 itself is lowered, and when the transport vehicle 1 is operated, the lifting section 4 is raised. .

Next, a pair of holes 10, 10 are formed in the inner side wall of the lifting section 4.
A retractable rod 11 that can retract and retract is provided diagonally forward (toward the towing part).

On the other hand, the pallet 7 corresponds to the retractable rod 11.
There is a retractable rod 1 on the side of the luggage rack for containers 9, etc.
A recess 12 is formed in which the connector 1 can be freely engaged and disengaged. As shown in FIG. 6, this recessed portion 12 has an arcuate wall surface, and a backing plate 13 is placed on the back surface of the front portion where the tip of the retractable rod 11 comes into contact for reinforcement. Furthermore, the lower plate 14 of this recess 12 is not horizontal but is formed in an oblique shape that descends toward the open side, so that the retractable rod 11 can be easily inserted into and locked in this recess 12.

Therefore, when loading and unloading the cargo cradle for pallets 7, containers 9, etc. onto and from the elevating section 4, the retractable rod 11 is recessed into the hole 10, and the cargo cradle is placed on the elevating section 4. Driving transport vehicle 1,
Alternatively, when lifting the front part of the elevating part 4 and tilting the elevating part 4 as a dump truck, use the retractable rod 1.
1 protrudes and locks into the recess 12 of the luggage tray,
It is designed to stably fix the luggage rack. Therefore, even when the transport vehicle 1 is started or stopped, the structure is such that the loaded cargo tray can be prevented from shifting.

Furthermore, the slanted lower plate that descends toward the open side of the arc-shaped recess securely fixes the cargo tray, and the vibration of the loaded object during transportation is extremely small compared to conventional horizontal recesses. , the load is less likely to collapse and can be loaded and transported safely.

In addition, since the retractable rod is provided in the hole in the inner wall of the elevating section, space for a container guide or the like is not required, and the product can be made smaller and lighter, and the structure is simpler and cheaper than conventional products.

The present invention has the above-described configuration, and therefore can provide a luggage carrying device in which a luggage holder can be stably mounted.

Claims (1)

[Claims] 1 A hole 10 is formed in the inner wall of the U-shaped lifting section 4 provided inside the U-shaped trailer chassis 3, and a retractable rod 1 projects obliquely forward from the hole 10.
1 is provided so as to be retractable into the hole 10, and on the other hand, the retractable rod 11 can be freely engaged and disengaged at the side of the luggage rack, and is formed in an oblique shape that descends toward the open side. A recess 12 having an arc-shaped wall surface is formed with the lower plate 14, and the retractable rod 11 is engaged with the recess 12, thereby fixing the luggage rack placed on the elevating part 4. A load carrying device.
