Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a hood device for a freight transport vehicle used in, for example, a steel mill premises.

[0002]

2. Description of the Related Art Conventionally, as a hood device for a freight transport vehicle of this type, there is a device disclosed in, for example, Japanese Utility Model Publication No. 46-20561.

That is, this conventional one is composed of rails laid on both ends of a gantry and a pair of hoods in which a film body is stretched over a plurality of gate-shaped frames which can run along the rails. A front plate and a rear plate are fixedly erected on both front and rear ends, and the end portions of the hood are connected to the front and rear plates. Then, the hood is opened by running the gate-shaped frame along the rails toward the ends.

[0004]

However, when the hood is opened in the above-mentioned conventional one, the hood is housed in a contracted state at both ends of the rail, so that work such as loading cargo is performed. Not only does this hinder the storage of cargo, but it also becomes impossible to store cargo at both ends of the pedestal, which greatly reduces the cargo loading space.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, and it is an object of the present invention to expand the cargo loading space by securing a storage space for the hood when the hood is opened. And

[0006]

[Means for Solving the Problems] That is, the means adopted by the present invention in order to solve the above-mentioned problems is that a rail 2 laid at a predetermined interval on a gantry 1 and traveling along the rail 2 are possible. And a hood 7 in which a film body 6 is stretched over a plurality of gate-shaped frames 3 connected to each other so that the hood 7 is opened when the hood 7 is opened. In order to be able to store the above, the gate-shaped frame 3 of the hood 7 is attached to the end of the rail 2.
The point is that a movable rail 33 capable of traveling is rotatably provided.

[0007]

Therefore, when the hood 7 is opened in the hood device characterized by the above-mentioned structure, the hood 7 is run along the gate-shaped frame 3 toward its end and the movable rail 33 in the stored state is moved. When it is rotated and connected to the rail 2, the gate frame 3 runs from the rail 2 to the movable rail 33 side, and the hood 7 is housed in the movable rail 33 in a contracted state. As a result, cargo can be loaded on the end side of the gantry 1.

The tips of the bent plates 39 fixed to both lower ends of the gate-shaped frame 3a located on one end side are fixed to a chain 27 suspended between the sprockets 26 as shown in FIG. .

This embodiment has the above-mentioned configuration,
Next, an example of its use will be described.

First, when the hood 7 is opened to load cargo on the gantry 1, the seat 8 attached to the gate-shaped frame 3a on one end side is tucked up, and the motor 34 is started to start the sprocket 35 and the chain. Rotation is transmitted to the support shaft 31 via the 37 and the sprocket 36, and each movable rail 33 rotates 90 ° about the support shaft 31 and stops when the movable rail 33 is aligned with the rail 2 and stops. Will be connected.

Thereafter, when the motor 10 is started, the drive shaft 11 is rotated via the sprocket 14, the chain 16 and the sprocket 13, and the rotary shaft 19 is rotationally driven via the sprocket 17, the chain 22 and the sprocket 20. .

The rotation of the rotary shaft 19 is transmitted to the support shaft 24 via another sprocket 21, a chain 38, and a sprocket 28 attached to the rotary shaft 19, and further the sprocket 26.
The chain 27 stretched in between rotates to the other end side.

Thus, the bent plate fixed to the chain 27
The gate-shaped frame 3a on one end side travels along the rail 2 to the other end side via 39, and each gate-shaped frame 3 travels from the rail 2 to the movable rail 33 while the film body 6 is folded. After that, when the gate-shaped frame 3a on one end side is moved to the movable rail 33 side, this is detected by a detection means (not shown) such as a limit switch, and the motor 10 is stopped.
Movable rail with the hood 7 contracted as shown by the alternate long and short dash line
It will be stored on 33.

Next, the cargo is loaded on the gantry 1 in this state. Since the entire hood 7 is stored on the movable rail 33, that is, because the storage space for the hood 7 is secured outside the gantry 1, The cargo can be loaded in the entire space of the gantry 1, so that the load can be significantly increased and the hood 7 does not hinder the cargo loading operation.

After the cargo is loaded on the gantry 1, the hood 7 is closed. In this case, the motor is reversed, as opposed to when it is opened.
When 10 is rotated in the reverse direction, the gate-shaped frame 3a on one end side travels from the movable rail 33 to the rail 2 side, and while the film body 6 is extended, the other gate-shaped frames 3 sequentially move to one end side. When the gate-shaped frame 3b on the other end side moves from the movable rail 33 to the rail 2 side, the detection means detects this and the motor 10
Stops.

Thereafter, the motor 34 is interlocked with the detection means.
Reversely rotates, and each movable rail 33 rotates 90 ° inward around the support shaft 31 and stops at the original position to be accommodated. If the seat body 8 is tucked down, the cargo is stored in this state. Hood 7
Is stored inside.

Thus, the hood device according to the present embodiment has an advantage that it can be manufactured easily and inexpensively because the whole structure is very simple.

In the above embodiment, the movable rail
Although the motor 34 is adopted as the drive means for rotating the 33, the drive means is not limited to this, and when the hood device is small, this drive means is omitted. It is possible and need not always be provided.

Further, the length of the movable rail 33 can be changed appropriately depending on the size of the hood 7 to be stored.

In addition, the specific structure of each part of the hood device can be arbitrarily changed in design within the scope intended by the present invention.

[0028]

As described above, according to the present invention, since the movable rail is provided at the end of the rail, the movable rail is rotated and connected to the rail when the hood is opened. By doing so, the hood can be housed by running the gate-shaped frame from the rail to the movable rail side. That is, since it becomes possible to secure the storage space of the hood outside the gantry, it is possible to obtain a special effect that cargo can be loaded in the entire space of the gantry without waste.

Further, since the hood device according to the present invention has a very simple structure as described above, it has a practical effect that it can be manufactured easily and at low cost.
