[Technical Field]

[0001] The present invention relates to a platform. [Background technology]

[0002] Traditionally, there was a platform for a waste incineration facility. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 4-127708 Summary of the Invention [Problem to be solved by the invention]

[0004] With conventional platforms, in order to make it easier to deposit waste through the loading door that opens and closes the opening to the waste pit at the waste incineration facility, users of the waste incineration facility had to drive their vehicles so that the rear of the vehicle was facing the loading door.As a result, there were cases where users were unable to safely position their vehicles properly, posing a risk of them falling into the waste pit due to driving errors. Furthermore, there are platforms equipped with turntables, such as those described in Patent Document 1. However, such platforms require a relatively large area for the turntable to be installed. Furthermore, such platforms require time to rotate the turntable to change the direction of the railcar, and the distance from the railcar to the loading door is long, so there is room for improvement in convenience.

[0005] An object of the present invention is to provide a safe and highly convenient platform. [Means for solving the problem]

[0006] The present invention has the following aspects. (1) One aspect of the platform according to the present invention is a platform adjacent to a garbage pit, and is equipped with a conveyor capable of transporting vehicles, the conveyor's transport direction facing the garbage pit. (2) In the above (1), the conveying direction may be oblique to the side wall surface of the garbage pit in a plan view. (3) In the above (2), an inclined surface may be provided between the floor surface of the platform and the side wall surface. (4) In (2) or (3) above, an opening leading to the garbage pit and capable of being opened and closed by a dump door may be provided, the opening surface of the opening being arranged diagonally relative to the side wall surface in a plan view, and the conveying direction being arranged perpendicular to the opening surface in a plan view. (5) In the above (1) or (2), the conveyor may include a first conveyor and a second conveyor arranged in parallel. (6) In the above (5), the conveyor located farthest from the entrance of the vehicle may have the longest transport distance. (7) In the above (1) or (2), the conveyor may be equipped with a load cell. (8) In the above (1) or (2), the conveyor may have a control device that can automatically stop transportation when the vehicle approaches the garbage pit. [Effects of the Invention]

[0007] According to the present invention, a safe and highly convenient platform can be provided. [Brief explanation of the drawings]

[0008] [Figure 1] FIG. 1 is a plan view showing a platform 100 according to an embodiment. [Figure 2] 1 is a cross-sectional view showing a platform 100 according to an embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0009] [Embodiment] The platform 100 according to the embodiment will be described below. Fig. 1 is a plan view showing a platform 100 according to an embodiment, and Fig. 2 is a cross-sectional view showing the platform 100 according to an embodiment.

[0010] The platform 100 according to the embodiment is used in a waste incineration facility 1, for example. The waste incineration facility 1 includes, for example, a platform 100 and a waste pit P adjacent to the platform 100, as shown in FIGS.

[0011] A user of the waste incineration facility drives a vehicle C loaded with waste G to be disposed of at the waste incineration facility, enters the platform 100, disposes of the loaded waste G in a waste pit P, and then exits the platform 100.

[0012] 1 and 2, the platform 100 has a flat floor surface 10 on which a vehicle C can travel. The platform 100 has, for example, a rectangular flat surface. 1, the platform 100 has an entrance 30 and an exit 50 for the vehicle C. The entrance 30 and the exit 50 may be located in the same place.

[0013] The platform 100 may be, for example, a vertically long rectangle having a width W in a plan view. This allows multiple conveyors 20 to be lined up along the side wall surface P1 of the garbage pit P. Then, garbage G can be simultaneously thrown into the garbage pit P through multiple openings 40.

[0014] The platform 100 is adjacent to the garbage pit P. The platform 100 is equipped with a conveyor 20 capable of transporting a vehicle C. The conveyor 20 has a conveying direction D facing the garbage pit P. As described above, the platform 100 is equipped with a conveyor 20 capable of transporting a vehicle C. This allows the movement of the vehicle C to be controlled by the conveyor 20 without relying on the user's driving operation. This avoids the risk of the vehicle C falling into the garbage pit P due to a user's driving error, and allows the vehicle C to be safely and appropriately positioned, for example, with the loading platform of the vehicle C facing the opening 40 leading to the garbage pit P. Furthermore, the conveyor 20 has a conveying direction D facing the garbage pit P. This allows the vehicle C to be transported toward the garbage pit P without the user having to drive the vehicle C in reverse. This allows the loading platform of the vehicle C loaded with garbage to be reliably faced toward the garbage pit P, making it easier to unload the garbage G from the loading platform and drop it into the garbage pit P. Therefore, a safe and highly convenient platform 100 can be provided.

[0015] The garbage pit P is a hole recessed below the level of the floor surface 10 of the platform 100. The garbage pit P is surrounded by side walls extending vertically and has a rectangular shape in a plan view. Garbage G is dropped into the garbage pit P. The garbage G in the garbage pit P is picked up by a garbage crane R and dumped into an incinerator (strictly speaking, a garbage dump hopper H) for incineration. The side walls of the garbage pit P have side wall surfaces P1, which are vertical surfaces that continue to the floor surface 10 of the platform 100.

[0016] The platform 100 preferably has an inclined surface T that connects the floor surface 10 and the side wall surface P1 of the platform 100. The inclined surface T is provided between the floor edge M of the floor surface 10 and the upper edge N of the side wall surface P1. Therefore, as shown in FIG. 2, the inclined surface T is inclined from the side wall surface P1 toward the floor surface 10 in a cross-sectional view. This allows garbage G dropped onto the inclined surface T to fall smoothly to the bottom of the garbage pit P by utilizing gravity, even if the opening surface 42 of the opening 40 and the side wall surface P1 are separated from each other in a plan view.

[0017] The conveyor 20 may be any type capable of transporting the vehicle C toward the garbage pit P, and may be, for example, a roller conveyor, a belt conveyor, or an apron conveyor. Note that the conveyor 20 may be capable of reciprocating as long as it is capable of transporting the vehicle C toward the garbage pit P.

[0018] The platform 100 may have a plurality of conveyors 20 arranged in parallel. In other words, the conveyors 20 may have a first conveyor 21 and a second conveyor 22 arranged in parallel. In this way, the first conveyor 21 and the second conveyor 22 are arranged in parallel. Specifically, for example, the conveying direction D of the first conveyor 21 and the conveying direction D of the second conveyor 22 are arranged so as to be parallel to each other. This allows the plurality of conveyors 20 to be arranged in a space-saving planar manner. In the example of the platform 100 shown in FIG. 1, five conveyors 20 are arranged in parallel.

[0019] Of the multiple conveyors 20, it is preferable that the conveyor 20 (the innermost conveyor 20E) that is located farthest from the entrance 30 for the vehicle C has the longest transport distance E. This allows a vehicle C with a relatively long vehicle length, such as a truck, to be preferentially placed on the innermost conveyor 20E, and a vehicle C with a relatively short vehicle length, such as a private car, to be placed on a conveyor 20 that is closer to the entrance 30 than the innermost conveyor 20E. Therefore, even if a vehicle C with a relatively long vehicle length is present on the platform 100, a wide area on the platform 100 can be secured for other vehicles C to pass through.

[0020] The conveyor 20 is preferably equipped with a load meter 23, which allows the weight of the vehicle C on the conveyor 20 to be measured. Therefore, for example, the weight of the vehicle C loaded with garbage G can be measured, and the weight of the vehicle C after the garbage G has been unloaded can be measured, and the weight of the unloaded garbage G can be calculated from the difference between these weights.

[0021] The conveyor 20 preferably has a control device 24 that can automatically stop conveyance when the vehicle C approaches the garbage pit P (or opening 40). The control device 24, for example, places a sensor that detects the blocking of a laser or the like by the vehicle C in a non-contact manner in front of the input door 41 (on the opposite side of the input door 41 from the garbage pit P), and when this sensor detects the vehicle C, controls the motor that drives the conveyor 20 to stop. This makes it possible to prevent the vehicle C from coming into contact with the opening 40 or input door 41 or falling into the garbage pit P.

[0022] In a plan view, the conveying direction D of the conveyor 20 is preferably arranged at an angle to the side wall surface P1 of the garbage pit P. In a plan view, the conveying direction D is preferably arranged at an angle of, for example, between 75 degrees and 45 degrees to the direction along the side wall surface P1, and more preferably at an angle of about 60 degrees. In this way, the conveying direction D of the conveyor 20 is arranged diagonally with respect to the side wall surface P1 of the garbage pit P in a plan view. This makes it possible to shorten the trajectory (e.g., the second trajectory r2 in FIG. 1) along which the user drives the vehicle C, and also to shorten the width W of the platform 100 (the depth in the vertical direction relative to the side wall surface P1 of the garbage pit P). Therefore, it is possible to provide a safe, compact, and highly convenient platform 100. Furthermore, because the platform 100 is compact, the construction area of ​​the platform 100 can be reduced, and construction costs can be reduced.

[0023] The platform 100 has an opening 40 that leads to the garbage pit P and can be opened and closed by a drop door 41. An opening surface 42 of the opening 40 is disposed at an angle to the side wall surface P1 in a plan view. Here, the conveying direction D is disposed perpendicular to the opening surface 42 in a plan view. This allows the loading platform of the vehicle C transported backward by the conveyor 20 to be positioned directly in front of the opening surface 42 of the opening 40. This also shortens the trajectory that the garbage G loaded on the loading platform must take to be dropped into the garbage pit P. This increases the convenience of the platform 100.

[0024] The drop-in door 41 may be a so-called double door, or may be a shutter that slides vertically, and may be capable of springing up around the top of the opening 40 from a state in which the opening surface 42 is closed to a state in which the opening surface 42 is open, and may be rotatable from the platform 100 side toward the garbage pit P side. The drop-in door 41 may be rotatable from the platform 100 side toward the garbage pit P side, around a pillar that extends vertically from the floor surface 10 of the platform 100. This allows the opening surface 42 of the opening 40 to be opened and closed freely even when the vehicle C is positioned close to the opening 40.

[0025] (action) Next, the operation of the platform 100 according to the embodiment will be described along the flow from when a vehicle C loaded with waste G enters the platform 100, unloads the waste G, and exits the platform 100.

[0026] (1) The vehicle C, with garbage G loaded on the rear loading platform, is directly driven by the user and enters the platform 100 from the entrance 30, and as shown by the white arrows in Figure 1, follows the first trajectory r1, then follows the second trajectory r2, turns (for example, 60 degrees) until the traveling direction of the vehicle C is aligned with the conveying direction D of the conveyor 20, and stops on the conveyor 20. At this time, the weight of the vehicle C with the garbage G loaded is measured appropriately by the load meter 23.

[0027] (2) Next, the vehicle C is transported by the conveyor 20 toward the garbage pit P (opening 40) backwards, with the loading platform facing the garbage pit P (opening 40). At this time, the transport of the vehicle C by the conveyor 20 automatically stops when the vehicle C approaches the opening 40 (or the drop-in door 41).

[0028] (3) When the vehicle C approaches the opening 40 (or the drop-in door 41), the drop-in door 41 is opened, and the garbage G is dropped into the opening 40 directly from the loading platform of the vehicle C or indirectly by hand, and then dropped into the garbage pit P.

[0029] (4) After the garbage G has been dropped into the garbage pit P, the weight of the vehicle C without the garbage G loaded is measured using the load meter 23 as appropriate. Then, the difference between the weight of the vehicle C with the garbage G loaded and the weight of the vehicle C without the garbage G loaded is calculated as appropriate.

[0030] (5) Next, after the garbage G loaded on the vehicle C is unloaded from the loading platform, the conveyor 20 is stopped and the user directly operates the vehicle C, causing it to move forward on the conveyor 20.

[0031] (6) Next, vehicle C heads toward exit 50 along third trajectory r3, and exits through exit 50 along fourth trajectory r4. In this way, according to the platform 100 of the embodiment, the movement line of the vehicle C from entering the platform 100, unloading the garbage G, to exiting can be shortened, and the driving operation of the vehicle C can be reduced.

[0032] Although the embodiments have been described above with reference to the drawings, the present invention is not limited to the above. Multiple features given as the embodiments may be freely combined.

[0033] The platform 100 according to this embodiment is adjacent to a garbage pit P. The platform 100 is equipped with a conveyor 20 capable of transporting a vehicle C. The conveyor 20 has a conveying direction D facing the garbage pit P. As described above, the platform 100 is equipped with a conveyor 20 capable of transporting a vehicle C. This allows the movement of the vehicle C to be controlled by the conveyor 20 without relying on the user's driving operation. This avoids the risk of the vehicle C falling into the garbage pit P due to a user's driving error, and allows the vehicle C to be safely and appropriately positioned, for example, with the loading platform of the vehicle C facing the opening 40 leading to the garbage pit P. Furthermore, the conveyor 20 has a conveying direction D facing the garbage pit P. This allows the vehicle C to be transported toward the garbage pit P without the user having to drive the vehicle C in reverse. This allows the loading platform of the vehicle C loaded with garbage to be reliably oriented toward the garbage pit P, making it easier to unload the garbage G from the loading platform and drop it into the garbage pit P. Therefore, a safe and highly convenient platform 100 can be provided.
