Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention is applicable to the leg suspension of a heavy truck, etc., which has a steerable and drivable wheel device in the lower part of the vehicle body frame. This invention relates to a protective cover that protects the cargo from rainwater and dust in a freight vehicle that is capable of loading and unloading pallets.

[Conventional technology]

For example, large and heavy cargo such as cold-rolled coils is loaded on a pallet with legs that support the pallet at a certain height above the ground with multiple left and right legs. After moving the pallet to the bottom of the pallet, the vehicle height is raised and the pallet is placed on the car body frame.

After placing the pallet on the car body frame as described above,
Cover the cargo on the valet with a protective cover to protect it from rainwater, etc.

[The key point that the invention attempts to solve]

Because the legs of pallets with legs protrude from both sides, it is not possible to use a hood-type cover like that attached to ordinary freight vehicles, and it is difficult to manually attach sheets to the cargo on the pallet. This method required a large amount of manpower and expense when the cargo was large, and it took time to unhook and unhook the sheets, which was the case in H31.

[Means for Solving Problem 5] In order to solve the above problems, the present invention provides a cover main body having a roof and both side walls on the body frame of a freight vehicle by attaching it only by a support frame at the front end. A space is provided between the side walls and both sides of the vehicle body frame to expose the legs on both sides of the pallet, and a flexible seal is provided to close this space, and the rear end opening of the cover body is opened and closed by power drive. A rear door is provided, a space is provided between the lower end of the rear door and the rear end of the vehicle body frame through which a pallet can go in and out, and a shutter that is opened and closed by power drive is provided in this space.

[For production]

This invention has the above-mentioned configuration, and when loading an empty pallet, the rear door is left in the closed position, only the shutter at the lower end is opened, and the vehicle is backed up with the body frame lowered, and the pallet is loaded. After the car body frame enters the lower part, when the car body frame is raised, the pallet is lifted by the car body frame, and the legs on both sides of the pallet are lifted off the ground.

In the case of loading an empty pallet as described above, the pallet enters the body frame from the space between the bottom of the rear door and the rear end of the body frame, and the legs on both sides of the pallet are connected to the lower edge of both side walls of the cover body and the body frame. The seal in this area is pushed outward by the upper end of the pallet leg.

After loading the pallets as described above, close the shutter at the bottom of the rear door and drive to the destination.

When loading a pallet with cargo, open the shutter at the bottom of the rear door and open the rear door, but the loading operation is the same as when loading an empty pallet, and after loading, close the rear door and shutter. Close it and drive to your destination.

Note that the operation for unloading the pallet from the vehicle body frame can be easily performed in three steps by reversing the above-mentioned loading operation.

〔Example〕

In FIGS. 1 and 2, 1 is a heavy truck, 2 is its body frame, and has a large number of steerable running wheels 3. The legs that support each wheel 3 are hydraulic cylinders, etc. The vehicle height can be freely changed by extending and contracting each leg.

Reference numeral 4 denotes a gate-shaped support frame fixed on the front part of the vehicle body frame 2. The front part of the cover body 5 that covers the cargo on the vehicle body frame 2 is fixed to this support frame 4, and the cover body 5 is secured by the support frame 4. is supported on a cantilever.

The cover main body 5 has a frame made of steel or the like, and a roof 7 and side walls 8 are formed by covering this frame with a metal plate 9 such as a steel plate or an aluminum plate. Although it is not clear in the figure, a metal plate such as a steel plate or an aluminum plate is also attached to the support frame 4 to form the front wall of the cover body 5.

A space 10 is provided between the lower edges of both side walls 8 of the cover main body 5 and both sides of the vehicle body frame 2, as shown in FIG. This space is closed by a seal 11 made of a flexible material such as rubber attached to the lower edge of the side wall 8, but only the upper edge of the seal 11 is fixed to the lower edge of the side wall 8, the rest being free.

Reference numeral 12 denotes a rear door, which, like the cover main body 5, is made of a metal plate such as a steel plate or an aluminum plate stretched over a frame. 14, it is rotatably attached to a bracket 15 at the upper rear end of the cover body 5.

The lower edge of the rear door 12 is connected to both side walls 8 of the cover main body 5.
A space is provided between the lower edge and the rear end of the vehicle body frame 2, and the upper edge of the shutter 17 made of a flexible material such as rubber is connected to the rear door. 1
Fix it to the lower edge of 2.

18 in Fig. 2 is a pair of left and right vertical cylinders fixed to the outside of the rear door 12, and the piston rod 1 is operated by hydraulic pressure.
9, whose lower ends are connected to left and right frames 20 fixed to the outside of the lower edge of the shutter 17.

21 are vertical guide tubes fixed to the outside of the rear door 12 so as to be located on both sides of each cylinder 18. Fixed at 20.

Reference numeral 25 denotes a pair of left and right cylinders attached to both sides of the upper rear end of the roof 7 of the cover body 5, which act by hydraulic pressure or the like.
The piston rod 26 is connected to the outer end of the plate 13 to open and close the rear door 12.

The operation of the above embodiment will be explained based on FIGS. 5 to 7. In these figures, 31 is a pallet with legs supported at a constant height from the ground by a plurality of legs 32 provided on the left and right sides, and 33 is cargo placed thereon.

First, as shown in Figure 5, place the car body frame 2 in front of the pallet 31.
is lowered, the cylinder 18 is activated to raise the shutter 17, and the cylinder 25 is activated to flip up the rear door 12 rearward and upward to fully open the rear opening of the cover body 5.

Next, the vehicle 1 is moved backward, and the vehicle body frame 2 is moved into the lower part of the pallet 31, as shown in FIG. At this time, the upper ends of the left and right legs 32 of the pallet 31 push open the seal 11 at the bottom of the side wall 8 and are located outside the vehicle body frame 2, as shown by chain lines in FIG.

As shown in FIG. 6, when the body frame 2 is confirmed to have completely entered the lower part of the pallet 31 and the body frame 2 is raised, the body frame 2 lifts the pallet 31 and lifts each of the left and right legs 32 from the ground. make it float.

Then, when the shutter 17 and the rear door 12 are lowered by the operation of the cylinder 18.25, the pallet 31 and the cargo 33 are moved to the cover body 5, the rear door 12, and the shutter 17, as shown in FIG.
and is completely surrounded by the seal 11.

As described above, the truck 1 loaded with the pallet 31 carrying the cargo 33 travels as it is to the destination ring and unloads the pallet 31, but the operation is the reverse of the loading operation.

Furthermore, empty pallets 31 can be easily loaded and unloaded by opening only the shutter 17 while keeping the rear door 12 closed.

〔effect〕

This invention provides a cover body having a roof and both side walls on the body frame of a truck, and the cover body has its front end mounted on a support frame on the front end of the body frame and is supported in a cantilevered manner. Moreover, since there is a space between the lower edges of both side walls and both sides of the car body frame, when loading and unloading a pallet with legs, the left and right legs of the pallet move out of the above space to the outside of both sides of the car body frame. I'm going to go out. Therefore, when loading and unloading a pallet with legs, there is no fear that the legs will get in the way, so the pallet can be easily loaded and unloaded.

Further, the space below the side walls of the cover body is closed off with seals, which are made of a flexible material and are pushed open by the legs of the pallet during loading and unloading of the pallet.

Therefore, this seal does not interfere with the loading and unloading of the pallet, and after the pallet is loaded, the spaces on both sides are completely closed off by the seal.

Furthermore, the opening at the rear of the cover body is opened and closed by the rear door, and when the rear door is closed, there is a space between the lower end of the rear door and the rear end of the vehicle body frame where a pallet can enter and exit. Pallets can be loaded and unloaded with the rear door closed.

Moreover, since there is a shutter on the lower edge of this rear door that is opened and closed by power, after loading the pallet, the shutter (closes the space at the lower end of the rear door), allowing the pallet and cargo inside the main body to be removed. It is completely covered and protected from rainwater and dust, and has the unique effect of allowing quick loading and unloading of pallets without much of the conventional manual labor.
