Description

[Detailed Description of the Invention] The present invention relates to a pit gate provided in a dust storage pit of an incinerator.

The timing of garbage, etc. to be thrown into an incinerator is regulated depending on the heat burning condition of the incinerator. Therefore, the dust collected by dust collection trucks, etc. is not put into the incinerator each time, but is temporarily stored in a dust storage pit adjacent to the incinerator, and is stored waiting for the above-mentioned time to put it in. It is controlled so that it is thrown into the incinerator from the dust pit. On the other hand, for the dust storage pit, a pit gate that can be opened and closed is installed between the truck stage (truck approach road and work area) and the dust storage pit (communication passage, etc.) for the work environment and safety.
These truck stages and dust storage pits are separated. The pit gate is opened and closed when the collected garbage is transferred from the truck to the dust storage pit.

The present invention is an improvement to such a pit gate to make it easier to install and to improve handling workability.The design consists of a mounting plate that is to be fixed on a vertical surface formed above the track stage. The base of the operating cylinder is pivotally supported on the upper part, and the upper end of the pit gate is pivotally supported on the lower part of the mounting plate, so that both pivot points are formed in the same vertical plane,
The gist is that the tip of the cylinder rod of the operating cylinder is pivotally attached to a bracket attached below the upper pivot point near the center of the pit gate.

The configuration and effects of the present invention will be explained below based on the drawings, but the following embodiment is only one specific example of the present invention, and the shape of the mounting plate and pit gate, and the pivot of the pit gate will be explained in accordance with the spirit of the above and below. Any changes to the design of the support structure etc. are included in the technical scope of the present invention.

FIG. 1 is an explanatory diagram illustrating the pit gate of the present invention, and shows the pit gate in a closed state.
FIG. 2 is a right side view of FIG. 1, partially cut away. FIG. 3 is an explanatory diagram corresponding to FIG. 1, and shows a state in which the pit gate is opened. In these figures, 1 is a pit gate, 2 is a gate mounting plate, 3 is a gate operating cylinder, and pit gate 1
The operating cylinder 3 is pivotally supported on a mounting plate 2 fixed to a vertical surface 6 of a shed (or a slag beam, etc.) via a gate bracket 4 and a cylinder bracket 5, respectively. The tip of the cylinder rod 3a of the operating cylinder 3 is pivotally connected to a bracket 8 attached to the approximate center of the pit gate 1.
In the illustrated example, five gate brackets 4 are provided, one of which is fixed to the mounting plate 2. The number of brackets 4 may also be changed as appropriate, such as two or three, depending on the size of the mounting plate 2. A pit gate 1 pivotally supported by a mounting plate 2 closes a charging gate 10 formed between a truck stage 9 and a shed 7, and is configured to partition a dust storage pit A side and a work area B.

When a truck that has collected garbage in such a state approaches the truck stage 9,
Operate the operating cylinder 3 to release the cylinder rod 3a.
, and lift pit gate 1. That is, the lever principle is applied to the pit gate 1, and the point of action at the lower end of the pit gate 1 is pivoted using the bracket 8 as a point of force and the gate bracket 4 as a fulcrum. At this time, the operating cylinder 3 also pivots using the cylinder bracket 5 as a fulcrum in the same way as the pit gate 1, but this moving distance is extremely small compared to the pivoting distance of the pit gate 1, so the operating cylinder has a short stroke. is applicable. When the input gate 10 is opened in this manner, the collected garbage on the truck is input into the dust storage pit. When the garbage input is completed, the truck is evacuated, the cylinder rod 3a is advanced, the pit gate 1 is moved in the opposite direction to the above direction, and the input gate 10 is closed. Reference numeral 12 is a cushioning material such as rubber, which softens the impact force between the pit gate 1 and the track stage 9 when the input gate is closed. Further, reference numeral 11 denotes an anchor, which enhances the integrity of the mounting plate 2 that pivotally supports the pit gate 1 and the vertical surface 6.

In conventional gates, pit gates, actuating cylinders, etc. are carried separately to the installation location, and then installed at appropriate locations such as sheds while aligning each other. However, since pit gates and the like are bulky and heavy, it is extremely difficult to install them in order to accurately center the center of rotation, and in some locations, it is necessary to reinforce the mounting part. . In contrast, in the present invention, the pit gate 1, the mounting plate 2, and the operating cylinder 3 can be manufactured in advance at a factory via the brackets 4, 5, 8, etc.
There is also no need to align the mounting plate 2 and the operating cylinder 3, making it extremely easy to install.

Since the present invention is configured as described above, the following effects can be obtained.

Since the pit gate can be operated with an extremely simple mechanism, it can be used for a long period of time with few failures.

Since the lever principle is applied, the pit gate can be turned significantly even if the driving length of the operating cylinder is short.

Since the pit gate, mounting plate, and operating cylinder are integrally constructed, installation work can be easily carried out.
