Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching and detaching the canopy of a transport vehicle operated as a trackless transport means on public roads or on premises used for loading and unloading heavy objects in steel works, refineries, shipyards, etc. The purpose of this is to remove the canopy from a transport vehicle without having to do the work of attaching and detaching it manually, when a canopy is required depending on the object of cargo handling or in case of rain, etc., or when removing the mounted canopy. To provide a method for attaching and detaching the top of a transport vehicle, which can be easily carried out by vertically moving a trailer chassis.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be explained below with reference to the drawings showing one embodiment.

First, an apparatus for carrying out the method of the present invention will be described in detail.

FIG. 1 shows an outline of a transport vehicle 1 used in the present invention, in which a trailer 4 having a U-shaped chassis 3 is connected to a tow truck 2.

This transport vehicle 1 is a U-shaped chassis 3 with a trailer 4.
The structure is such that it is equipped with various removable attachments such as containers, flats, and pallets, and is capable of lifting various oddly shaped heavy objects and transporting them by the towing truck 2. The vertical movement of the U-shaped chassis 3 of the transport vehicle 1 is performed by the operation of a hydraulic cylinder appropriately installed between the trailer 4 and the U-shaped chassis 3.

A lower frame 6, which is one side of a canopy main body 5 configured as a two-part body, is fixed to the trailer 4, and a colorless and transparent acrylic plate 7 is attached to the lower frame 6 frame.

On the other hand, the upper frame 8 of the canopy main body 5, which is detachable, is held by a support (not shown) protruding from the inside of the upper frame 8 on the support frame 10 of the canopy removable pallet 9 shown in FIG. There is.

A colorless and transparent acrylic plate 11 is attached to the upper frame 8 in the same manner as the lower frame 6, and a roof made of a plastic corrugated plate 12 is provided on the upper part of the upper frame 8.

Further, legs 13 are secured to the top attaching/detachable pallet 9 by pins 14 so as to be slidable up and down. (Details will be explained in FIG. 9.) Therefore, the method of the present invention is implemented as follows. First, the trailer 4 with the lower frame 6 shown in FIG. 3 fixed thereon is moved to a position where the removable hood pallet 9 holding the upper frame 8 shown in FIG. 4 can be mounted.

Then, as shown in FIG. 5, the lower frame 6 is placed directly under the upper frame 8.

Next, raise the U-shaped chassis 3 in this state,
Lift up the hood removable pallet 9 a little.

Then, the load on the leg 13 of the top attaching/detachable pallet 9, which is locked by the pin 14, is removed, so the pin 14, which will be described in detail later, can be easily removed, and the locking of the top attaching/detachable pallet 9 and the leg 13 is removed. It comes off.

Therefore, when the U-shaped chassis 3 is lowered, the top attaching/detachable pallet 9 also slides on the legs 13 and lowers accordingly, so that the upper frame 8 held by the support frame 10 also lowers.

Then, the upper frame 8 frame becomes the lower frame 6 frame.
It fits into a frame receiving part 15 formed on the frame. (Details will be explained in FIG. 10.) Furthermore, as the U-shaped chassis 3 descends, only the support frame 10 descends, so the upper frame 8 is released from the support frame 10 and is supported only by the lower frame 6. The state will be as follows.

Furthermore, a stand 1 provided in the center of the hood removable pallet 9
The U-shaped chassis 3 is lowered until the robot 6 lands on the ground.
Then, the hood removable pallet 9 is released from being held by the U-shaped chassis 3, and the two are separated from each other.

Subsequently, when the towing truck 2 is moved forward and the trailer 4 is pulled out from the hood attachment/detachment pallet 9, the upper frame 8 is mounted on the lower frame 6 as shown in FIG. 6, and the hood attachment operation is completed. .

Further, the hood attaching/detachable pallet 9 that held the upper frame 8 is in an attachable/detachable state with the platform 16 being lowered, as shown in FIG.

FIG. 8 shows a state in which the canopy body 5, which is configured as a two-part body consisting of the upper frame 8 and the lower frame 6, is attached to the trailer 4, as seen from the rear. This is a state where the overslide door 17 installed on the ceiling is lowered. A colorless and transparent acrylic plate 18 is attached to this overslide door 17 as well, like the upper and lower frames 6 and 8.

Figure 9 shows that the hood removable pallet 9 and leg 13 are connected to pin 1.
4 shows the details of the locked state.

The hood removable pallet 9 is provided with a fixing frame 20 in which a pin hole 19 is formed, and the leg 13 is provided with a fitting hole 21 at the top in alignment with the pin hole 19.
is formed, so the hood removable pallet 9 and leg 1
3 is locked by a pin 14.

Therefore, in order to remove the pin 14 from the locked state, move the hood removable pallet 9 to the U-shaped chassis 3.
Accordingly, if you raise it a little, leg 1 will move accordingly.
The load of the hood removable pallet 9 on 3 is eliminated,
The weight of the hood attachment/detachment pallet 9 is no longer applied to the pin 14, and the pin 14 can be easily removed.

FIG. 10 is an explanatory diagram showing a state in which the eight upper frames fit into the six lower frames. The eight upper frames have a rectangular shape, and the six lower frames have an H shape. The frame receiving portion 15 is formed by providing guide pieces 22 at several locations.

Therefore, when the upper frame 8 is lowered as explained in FIG. 5, the rectangular upper frame 8
The frame is a guide piece 22 provided on the lower frame 6 frame.
It will be guided and fitted into the H-shaped lower frame 6 frame.

The case in which the top body 5 is attached to the trailer 4 has been described above in the order shown in FIGS. 1 to 10. Next, the case in which the top is removed will be described.

In other words, it is sufficient to perform the operation in the reverse order of the above-mentioned mounting method, but first, as shown in FIG. , the trailer 4 on which the canopy body 5 is mounted is moved to a position where the upper frame 8 of the canopy body 5 is held by the support frame 10 of the canopy attachment/detachment pallet 9.

Next, when the U-shaped chassis 3 is raised and the hood attachment/detachment pallet 9 is raised, the support frame 10 is raised accordingly, pushing up a support (not shown) protruding from the inside of the upper frame 8. Upper frame 8
Then, the lower frame 6 is disengaged, and the upper frame 8 is further raised.

Then, the pin hole 19 formed in the fixing frame 20 of the top attaching/detachable pallet 9 is aligned with the fitting hole 21 formed in the upper part of the leg 13, and after locking with the pin 14, the U-shaped chassis 3 is further lowered. , pull out the trailer 4 from the hood attachment/detachment pallet 9.

By the above-described operation method, the upper frame 8 of the top body 5 can be returned to the support frame 10 of the top attaching/detachable pallet 9 where it was initially held, as shown in FIG.

This invention has the above-described configuration, and therefore, when a hood is required in rainy weather, or when a hood is not required in sunny weather, the hood can be attached and removed without manual work. This can be done quickly and easily by vertically moving the trailer chassis of the transport vehicle.
