Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a front lock device for preventing containers from falling due to forgetting to engage the side lock device, abnormal operation or failure of the side lock device in a luggage carrier. It is something.

[Conventional technology]

Conventionally, in cargo transport vehicles used in steel mills, smelters, shipyards, etc., a U-shaped trailer chassis is connected to the rear of the towing part of the truck, and this trailer chassis is used to transport heavy objects, large-capacity objects, etc. Alternatively, various types of removable containers are mounted to accommodate various objects to be transported, such as long objects, and a side lock device is provided for safe loading of the containers.

[Problems to be solved by the invention] However, the side lock device alone cannot maintain safety in the event of forgetting to engage the side lock, abnormal operation, or failure. Therefore, the object of this invention is to provide a front lock device as an auxiliary means for the side lock device.

[Means for solving problems]

Therefore, in this design, the trailer chassis 3
An inner frame 4 that moves up and down is provided inside the
Accordingly, in a luggage carrier that loads and unloads the container 6, the front plate 11 of the container 6 is
A bracket 13 having a hook portion 12 on the outer surface of the bracket 13
a lock frame 16 having a locking hole 15 on the outer surface of the front plate 14 of the inner frame 4;
is fixed, and by raising the inner frame 4,
The hook portion 12 of the bracket 13 is inserted into the locking hole 15 of the lock frame 16.

[Effect]

Because of the above measures, even if the side lock device is forgotten to engage, malfunctions, or malfunctions, the hook part of the bracket will always be locked in the locking hole of the lock frame, so the container can be attached to the inner frame of the trailer chassis. It won't fall off.

〔Example〕

The configuration of this invention will be explained below with reference to the drawings shown as examples.

First, as shown in FIG. 1, a luggage carrier 1 consists of a truck 2 and a U-shaped trailer chassis 3 connected to the rear of the truck 2. This trailer chassis 3 is provided with a U-shaped inner frame 4 on the inside, and as shown in FIG. is forming.

FIG. 3 shows a container 6 for objects to be transported, which is mounted on the inner frame 4 of the trailer chassis 3 for transportation. In this case, the horizontal portion 5 supports the container 6 from below. Further, when loading or unloading the container 6 on the inner frame 4, the inner frame 4 itself is lowered, and when the luggage carrier 1 is driven, the inner frame 4 is raised.

The side lock device includes a retractable rod 8 that is provided in a pair of holes 7, 7 formed on the inner surface of the inner frame 4, and a retractable rod 8 that can be freely retracted from the side of the container 6 corresponding to the retractable rod 8. It consists of a recess 9 formed to be able to engage and disengage.

The front lock device is attached to the front plate 1 of the container 6.
1, and a front plate 14 of the inner frame 4.
It consists of a lock frame 16 having a locking hole 15 fixed to the outer surface of the lock frame 16. Incidentally, from the viewpoint of stability of the container 6 when mounted on the inner frame 4, it is preferable that the bracket 13 and the lock frame 16 are set in pairs as shown. Further, a bumper 17 may be attached to the inner surface of the front plate 14 of the inner frame 4 in order to buffer the impact when the container 6 is mounted on the inner frame 4.

Therefore, when loading or unloading the container 6 on the inner frame 4 of the trailer chassis 3, the retractable rod 8 of the side lock device is recessed into the hole 7, and the container 6 is placed on the inner frame 4 and the cargo is loaded. When driving the transport vehicle 1 or tilting the inner frame 4 by lifting the front part of the inner frame 4, the retractable rod 8 is projected and locked in the recess 9 of the container 6.
The container 6 is fixed.

However, if the side lock device is forgotten to engage, or if the side lock device malfunctions or breaks down, there is a risk that the container 6 may slip off the inner frame 4.

Therefore, the front lock device of this invention works as an auxiliary means. In other words, since the container 6 is always locked to the inner frame 4 by the front locking device, the loaded container will remain secure even when the luggage carrier starts or stops, or when the inner frame 4 is tilted. Misaligned or
It can prevent it from falling.

[Effect of idea]

As described above, in the container front lock device of the luggage carrier of this invention, the hook portion 12 of the bracket 13 fixed to the container 6 locks the lock frame 1 fixed to the inner frame 4.
Since it is always locked in the locking hole 15 of No. 6, it is possible to maintain safety in the event of forgetting to engage the side lock device, abnormal operation, or failure, and has an excellent effect.
