DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crane operation room of a refuse disposal plant provided for operating a crane for carrying out refuse in a refuse incineration plant or the like.

[0002]

2. Description of the Related Art FIG. 4 is a vertical sectional side view showing an example of a main part of a conventional refuse treatment plant. A truck a which has collected garbage throws garbage into a garbage pit b. I have. A crane c is provided above the waste pit b. The bucket d of the crane c carries out the waste in the waste pit b to the hopper e, and transports the waste from the hopper e to the incinerator (not shown) by the conveyor f for incineration. ing.

An operation room g is installed on one side above the refuse pit b, and a glass h slightly protruding toward the refuse pit b is attached to the front of the operation room g. An operation panel of the crane c is provided in the operation room g, and the operation of the crane c is performed while observing the state of the waste pit b in the operation room g.

[0004] From the refuse pit b, dust and water soar by the input of refuse to pollute the glass h, or water vapor generated by fermentation of refuse adheres to the outer surface of the glass h.
Since dust adheres to the surface and becomes contaminated, the outer surface of the glass h often needs to be cleaned in order to keep the view inside the dust pit b.

[0005]

The glass h of the operation room g installed in the conventional refuse treatment plant is fixed in such a manner that it slightly projects toward the garbage pit b so that the inside of the garbage pit b can be seen directly below. Therefore, it is dangerous to clean the outer surface of the glass h, and furthermore, the odor of the garbage is so great that cleaning by a person is impossible. For this purpose, a device for automatically cleaning the outer surface of the glass h has been considered,
In addition to being very expensive, it has a problem that it cannot be maintained for the same reason as described above.

Further, since the glass h slightly protrudes toward the dust pit b, it is necessary to prevent the bucket d of the crane c from hitting the glass h, and there is a disadvantage that the moving range of the crane c is restricted. Was.

The present invention eliminates such conventional disadvantages,
It is an object of the present invention to provide a crane operation room of a refuse disposal site that can easily clean glass in front of an operation room and does not limit the moving range of the crane.

[0008]

A crane operating room of a waste disposal site according to the present invention is provided with a waste pit into which waste is put and a waste pit provided above the waste pit and carried into the waste pit. A crane, an operation room accommodating space formed on one side of the garbage pit, a shutter provided between the operation room accommodating space and the garbage pit, and the operation room movably with respect to the garbage pit. An operation room provided in the storage space and having a glass window facing the waste pit and operating the crane therein.

[0009]

[Function] When cleaning the outer surface of the glass window, retract the operation room from the garbage pit and close the shutter to perform cleaning work on the floor of the operation room isolated from the garbage pit. When the glass windows in the control room restrict the movement of the crane, the control room can be retracted from the waste pit.

Can be conveyed to an incinerator (not shown) by a conveyor 8 for incineration.

FIG. 2 is an enlarged vertical sectional side view of the operation room accommodating space 4, and FIG. 3 is a cross-sectional plan view of FIG. 2. As shown in these figures, a dust pit 1 is provided on the floor of the operation room accommodating space 4. Is laid, and the operation room 10 is moved by wheels 12 rotated by an electric driving device 11.
Along the garbage pit 1. A stopper 13 is provided at the end of the rail 9.
The movement of the operation room 10 is stopped at the end of the rail 9.

The operation room 10 is provided with a glass window 14 slightly protruding from the side facing the waste pit 1 so that the inside of the waste pit 1 and the crane 3 (FIG.
See)). The operation of the crane 3 can be performed from the operation room 10. In the rear of the operation room 10, a bellows-type passage 15,
Doors 16 and 16 are provided so that traffic can pass between the rear of the operation room 10 and the rear of the operation room housing space 4.

As shown in FIG. 2, a shutter 17 is provided between the operation room accommodating space 4 and the refuse pit 1 so as to be openable and closable, and the operation room 10 is retracted into the operation room accommodating space 4. When the shutter 17 is lowered from the shutter box 18 in this state, the space between the operation room storage space 4 and the waste pit 1 can be partitioned.

As shown in FIG. 2, an air supply fan 19 is attached to a rear portion of the operation room accommodating space 4, so that outside air can be sent to the operation room accommodating space 4, and FIG. As shown, compartments 21 separated by doors 20, 20
Is provided, passes through the compartment 21, and the operation room accommodation space 4
People can pass between the inside and outside of the building.

Next, the operation will be described.

As shown in FIG. 1, the truck 6 that has collected the garbage throws the garbage from the platform 5 into the garbage pit 1. The garbage collected in the garbage pit 1 is carried out of the garbage pit 1 by the bucket 2 of the crane 3 and
It is conveyed to an incinerator (not shown) by the conveyor 8 and incinerated. At this time, the shutter 17 shown in FIG. 2 is opened, and the operation room 10 is advanced toward the refuse pit 1 as shown by a two-dot chain line, so that the crane 3 (see FIG. 1). When the moving range of the bucket 2 of the crane 3 is hindered by the glass window 14, the operation of the crane 3 is caused by the projection of the glass window 14 by moving the operation room 10 to the back of the operation room housing space 4.
