Description

  The present invention relates to a waste material transport container in which waste materials such as household waste, waste, sludge, and residual soil in the waste material processing field are accommodated and transported.

  Conventionally, a waste material transport container that can be loaded and unloaded on a transport vehicle is a box shape with a substantially U-shaped cross section, and a discharge door is attached to the rear part of the container so that the waste material can be stored or discharged in the container. I am doing so. Containers are loaded onto and unloaded from transport vehicles with cranes or hydraulic equipment, and waste materials such as household waste, waste, sludge, and soil are transported to a disposal site for disposal.

  However, in a general waste container, although the cross section is a substantially U-shaped box shape, the lower portions on both sides of the inner surface member are right-angled or bent at a predetermined angle. Yes. Therefore, the container is tilted with a transport vehicle to discharge the contents, but waste materials such as household waste, waste, sludge, and residual soil adhere to the corners on both sides, and the waste material falls smoothly. The corner portion was easily corroded by the waste material that was not attached or adhered. In addition, even when waste material is thrown into the container, the waste material hits the side surface or the lower corner of the container and the inner surface member is deformed and is easily damaged.

Therefore, it has been desired that the waste material transport container can smoothly discharge the waste material without adhering to the corner portion, and can be durable without being damaged as much as possible.
Therefore, the applicant has developed a container having smooth curved surfaces on both sides of the inner surface, such as utility model registration No. 3039451 and Japanese Patent Application Laid-Open No. 2008-62954, and has been well received. .

Utility Model Registration No. 3039451 JP 2008-62954 A

  However, since the container is as large as 2800 to 6700 mm in length, 1600 to 2300 mm in width, and 1200 to 1900 mm in height, the lower side surfaces of both sides are molded into a curved shape with a predetermined diameter of 100 to 300 mmR. In addition, a large press forming device with high output is required, and the molded container is easily deformed or deformed during use, and it is difficult to lose shape or deform with a simple press forming device with as little output as possible. The challenge was to use containers.

  Therefore, as in Patent Document 1 and Patent Document 2, the container is made of wear-resistant, high-strength Swedish steel, and the corners on both sides of the container are curved with a curvature radius of 100 to 300 mm. In order to form a curved surface, a pressed bent portion is formed by pressing the steel plate sequentially through a mold at intervals of 10 to 20 mm and pressing the curved surface with a curvature radius of 100 to 300 mm.

  However, although Swedish steel has wear resistance and high tension even though it is thin, it can reduce the weight and durability of the container, but it is very expensive, so it has been a problem to reduce the price of the container.

  The present invention has been made in view of the above points, and in order to solve the above-described problems, the present invention is a waste material transport container that houses and transports waste materials such as household waste, waste, sludge, and residual soil in a container. The bottom plate of the container is made of wear-resistant, high-strength Swedish steel, and the steel plate including general structural rolled steel and welded structural steel on both sides of the bottom plate of the container is 100 to 300 mm. It is another object of the present invention to provide a container for transporting waste material, characterized in that a container is formed by joining side plates integrally formed with curved corner portions having a radius of curvature.

  Also, a waste material transporting container for transporting waste materials such as household waste, waste, sludge, and residual soil in a container, having a curved shape with a curvature radius of 100 to 300 mm on both sides of a bottom plate portion on the bottom surface of the container. The corners are made of wear-resistant, high-strength Swedish steel, and side plates made of steel, including general structural rolled steel and welded structural rolled steel, are installed on both sides of the bottom of the container. The object is to provide a container for transporting waste material, characterized in that the containers are formed by joining them.

  Another object of the present invention is to provide a container for transporting waste materials in which a bottom plate on the bottom surface of the container is wear-resistant and a high-strength Swedish steel plate is formed in a mountain shape or a valley shape.

  Furthermore, the both side plates of the container are divided into an upper plate and a lower plate, respectively, and a bent reinforcing portion including a curved shape that bulges outward along the longitudinal direction of the container is provided on each of the divided upper plate and lower plate. An object of the present invention is to provide a container for transporting waste material, wherein the side plate is formed by integrally joining the bent reinforcing portion of the upper plate and the bent reinforcing portion of the lower plate which are divided into upper and lower parts.

  Still another object of the present invention is to provide a waste material transporting container in which a wear-resistant, high-strength Swedish steel plate is 3 to 4 mm thick.

  The waste material transport container of the present invention is a waste material transport container for storing and transporting waste materials such as household waste, waste, sludge, and residual soil in the container as described in claim 1. In addition, wear-resistant, high-strength Swedish steel plates are used for the bottom plate of the bottom of the container, and rolled steel for general structure or rolled steel for welded structure is steel with a curvature of 100 to 300 mm on both sides of the bottom plate of the container. By forming the container by joining the side plates that integrally formed the corners of the curved surface shape of the radius, the bottom of the container is reduced in weight and strength as wear-resistant, high-strength Swedish steel. It is made of steel including general structural rolled steel and welded structural rolled steel, which reduces the price. Household waste, waste, sludge, residual soil and other waste materials are stored in a container. The possible discharge process so that waste does not stagnate in the truck.

  Moreover, the waste material transport container of the present invention is a waste material transport container according to claim 2, wherein the waste material transport container accommodates and transports waste materials such as household waste, waste, sludge, and residual soil in the container. It is assumed that curved corners with a radius of curvature of 100 to 300 mm are integrally provided with wear-resistant, high-strength Swedish steel plates on both sides of the bottom plate portion of the bottom of the container. By forming containers by joining side plates made of steel including structural rolled steel and welded structural rolled steel, the bottom and corners of the container have wear resistance, and high-strength Swedish steel reduces weight and strength. The two sides are made of steel materials including rolled steel for general structures and rolled steel for welded structures to reduce the price, and waste materials such as household waste, waste, sludge, and residual soil are used as containers. And contents, can be discharged treated as waste this container to the truck is not stagnant.

  Furthermore, the waste material transport container according to the present invention is as described above by forming the wear-resistant, high-tension Swedish steel plate in the shape of a mountain or valley in the bottom plate on the bottom of the container. The wear resistance of the container and the bottom surface of the high-strength Swedish steel can be reinforced to improve the strength of the container.

  Furthermore, the waste material transporting container according to the present invention, as described in claim 4, divides both side plates of the container into an upper plate and a lower plate, respectively, and divides the upper plate and the lower plate into the longitudinal direction of the container. Accordingly, a bending reinforcement portion including a curved shape bulging outward is provided, and the side plate is formed by integrally joining the bending reinforcement portion of the upper plate and the bending reinforcement portion of the lower plate divided vertically. As a result, the side surface of the container is reinforced, and it can be prevented from being deformed or deformed during use, and can be used with good durability.

  Furthermore, the waste material transport container according to the present invention has a high tensile strength, as described above, by using a wear-resistant, high-strength Swedish steel plate having a thickness of 3 to 4 mm. The Swedish steel can be made as light and strong as possible, reducing costs.

  The waste material transport container of the present invention is a waste material transport container that houses and transports waste materials such as household waste, waste, sludge, and residual soil in a container, and has a wear-resistant, high tensile strength on the bottom plate of the container. A Swedish steel plate was used, and curved corners with a curvature radius of 100 to 300 mm were integrally formed on both sides of the bottom plate at the bottom of this container with steel materials including general structural rolled steel materials and rolled steel materials for welded structures. It is characterized in that the side plates are joined together to form a container.

  As shown in FIGS. 1 and 2, the container 1 for transporting waste materials can be loaded and unloaded on a transport vehicle 2 such as a truck, and is mounted and integrated. Waste materials such as household waste, waste, sludge, and residual soil 3 and 4, the container 1 has a lower curved side surface as shown in FIGS. 3 and 4 and a discharge door 3 that can be opened and closed at the rear. It is designed to discharge smoothly so that it does not stick or stagnate.

  As shown in FIGS. 3 and 4, the container 1 uses a wear-resistant, high-strength Swedish steel plate for the bottom plate 4 on the bottom surface, and general structural rolled steel, hot-rolled steel plate, and welds on both sides of the bottom plate 4 on the bottom. Side plates 6 integrally formed with a curved corner portion 5 having a radius of curvature of 100 to 300 mm made of steel including structural rolled steel, mechanical structural carbon steel, and stainless rolled steel are integrally joined by welding. Yes.

  The steel plate of the bottom plate 4 of the container 1 is 3 to 4 mm thick and, if necessary, 4 to 6 mm thick Swedish steel (Hardox or Domex wear-resistant steel, high-tensile steel plate of Sweden Steel) or equivalent strength. It is preferable to use a steel plate, and the container 1 can be as light and strong as possible. As will be described later, the bottom plate 4 of the container 1 can further reinforce the bottom surface as a gentle mountain shape or valley shape. Swedish steel is several times higher in price than general steel materials, and is used for the bottom plate 4 of the container 1 to reduce the cost.

  A rolled steel material for general structure, in which curved corner portions 5 having a radius of curvature of 100 to 300 mm are integrally formed on both sides of the bottom plate 4 on the bottom surface of the container 1 as shown in FIGS. The side plates 6 of steel materials including rolled steel plates, rolled steel materials for welded structures, carbon steel materials for machine structures, and stainless steel rolled steel materials are welded and joined together to reduce costs.

  The above-mentioned side plate 6 includes SS41, SS50, SPN1, SPN2, SM41, SM42, S10C, S20C, SUS21, SUS24 and other general structural rolled steel materials, hot rolled steel plates, welded structural rolled steel materials, mechanical structural carbon steel materials, stainless steel Steel material such as rolled steel can be used, and it is joined using 3 to 6 mm of the same thickness as the above-mentioned Swedish steel, and it is inferior in wear resistance and high tension compared to Swedish steel, but the curved surface of the corner portion 5 It is easy to mold the shape, and the price is low, so the cost can be reduced.

  In order to form the corner portions 5 on both sides of the lower portion of the container 1 into a curved shape having a predetermined radius of curvature of 100 to 300 mmR, the container perpendicular to the discharge door 3 on the end surface is formed on the steel plate of the curved portion of the corner portion 5. Along the longitudinal direction, that is, in parallel, at a predetermined interval of 10 to 50 mm, pressing is performed as shown in FIG. 5 by press molding, and each corner portion 5 is bent to be formed into a curved shape. The curved surface portions on both side surfaces of 1 can be formed as smoothly as possible, and adhesion of dust and the like can be effectively prevented.

  As the press molding device, for example, a lower mold is provided with a concave portion having a curved surface with a predetermined width of 20 to 60 mm, and an upper die is provided with a convex portion having a curved surface with a predetermined width of 10 to 50 mm, A steel plate with a predetermined thickness and width is fed 10-50 mm at a time, the upper die is lowered, and the steel plate is folded at 90 degrees from the bottom to the side from the front end to the rear end by pressurizing about 1-2 mm with a predetermined output. It can be bent and formed into the required curved shape.

  By doing so, the side member can be formed by bending the steel plate into a required curved shape through a relatively small output press forming device without the need for a high output press forming device, and the container The one corner portion 5 can be reinforced, and can be used with good durability because it can be prevented from being deformed or deformed during use. In addition, the corner part 5 of the container 1 can also be press-molded as usual.

  1 to 4, the side plates 6 on both sides of the container 1 are divided into an upper plate 7 and a lower plate 8, respectively, and the divided upper plate 7 and lower plate 8 are arranged along the longitudinal direction of the container 1. The bending reinforcement portions of the upper plate 7 divided into upper and lower portions are provided with bending reinforcement portions 9 and 10 each having an outwardly bulging cross-section, such as an arcuate curved surface shape, a hexagonal shape, or an octagonal shape. 9 and the bent reinforcing portion 10 of the lower plate 8 are overlapped or butted together and welded together.

  Both side portions of the container 1 are made of steel such as structural rolled steel. However, the bent reinforcing portions 9 and 10 can be overlapped and welded together to be integrally joined for reinforcement and can be used with good durability. . Moreover, since the container 1 is divided and joined to the bottom plate 6, the upper plate 7, and the lower plate 8, a large steel plate is not required, and a fixed-size steel plate is reduced to a half or the like. Since it can be divided into an appropriate size into the above dimensions, it can be molded economically. Moreover, it is not necessary to bend a large steel plate integrally, and it is preferable because it can be formed by a relatively small press forming apparatus and space can be saved.

  Further, as the bending reinforcing means for the side plate 6, as shown in FIG. 6 (a), only the outer side portion of the side plate 6 is formed in a curved shape or the like by welding and joining to the inner side portion, or as shown in FIG. The volume of the container 1 can be increased by bending the bent reinforcing portions 9 and 10 of the container 1 to the upper side plate 7 and the lower side plate 8 as shown in FIG.

  The lower part of the divided upper plate 7 of the side plate 6 on the both sides of the container 1 and the upper part of the lower plate 8, etc. are cross-sectionally bulged outwardly along the longitudinal direction of the container 1 as shown in FIG. U-shaped curved reinforcement parts 9 and 10 are provided, respectively, and the lower and upper bending reinforcement parts 9 and 10 of the upper and lower plates 7 and 8 are overlapped. They can also be joined together by welding, and means that are easy to mold can be employed.

  Further, the bent reinforcing portions 9 and 10 of the upper plate 7 and the lower plate 8 are welded as a plurality of two or more stages as shown in FIGS. In addition to reinforcing, the volume of waste material can be increased.

  9A and 9B, the bottom plate 4 on the bottom surface of the container 1 is formed of a wear-resistant, high-strength Swedish steel plate in a gentle mountain shape, an obtuse angle shape, or the like. In particular, it is preferable that the central portion has a gradient of about 3 to 10 degrees, more preferably 5 to 10 degrees. If the gradient is small, the reinforcing effect is small, and if the gradient is large, the strength can be improved. However, it is not preferable because the volume of the container 1 is reduced and waste materials are easily accumulated at the bottom. In addition, the reinforcement material 11 can be further provided in the lower part of these reinforcement parts, and the intensity | strength of a bottom face can also be improved.

  10 (a) and 10 (b), the wear resistance of the bottom plate 4 on the bottom surface of the container 1 and a high-tension Swedish steel plate are formed into a gentle valley shape, obtuse angle shape, or the like. In particular, it is preferable that the central portion has a gradient of about −3 to −10 degrees, more preferably −5 to −10 degrees. When the gradient is small, the reinforcing effect is small, and when the gradient is large, the strength can be improved and the volume of the container 1 can be increased, which is preferable. Moreover, the water | moisture content contained in a waste material is collected in the center part, and it can discharge | emit, and is preferable.

  Further, as shown in FIGS. 11A and 11B, curved corner portions 5 having a radius of curvature of 100 to 300 mm are formed on both sides of the bottom plate 4 on the bottom surface of the container 1 with a wear-resistant, high-tension Swedish steel plate. The bottom surface provided integrally is formed on both sides of the bottom surface of the container 1 with general structural rolled steel, slightly hot rolled steel, welded structural rolled steel, mechanical structural carbon steel, and stainless steel including stainless steel. The side plates 6 can be welded and joined together to form the container 1. Also in this case, wear resistance of the bottom surface of the container 1 and the corner 5 and high-strength Swedish steel can be reduced in weight and strength, and the price can be reduced, such as household waste, waste, sludge, residual soil, etc. Waste material can be accommodated in a container, and the container can be discharged so that the waste material does not stagnate in the transport vehicle.

  In the above description, the side plates 6 on both sides of the container 1 are divided into upper and lower parts and joined. However, the upper and lower parts can be integrally formed as a single piece, and further divided and joined appropriately in the front-rear direction. Therefore, it is possible to implement a modified embodiment based on the above-described gist of the present invention.

  On the outer peripheral surface of the container 1 formed in this way, the upper end portion is bent as shown in FIGS. 1 and 2 to form the reinforcing portion 12, or the reinforcing material of the channel material is welded parallel to the upper portion. A container attaching part 14 can be installed on the bottom of the container 1 and the legs 13 are directly welded to the bottom of the container 1 in the same manner as a conventional container, so that the container 2 can be unloaded and can be mounted integrally. The front and rear wall surfaces 15 of the container 1 can be configured in substantially the same manner as in the prior art so that the transport vehicle 2 does not feel uncomfortable and can be used in the same manner as in the past.

The container 1 for transporting the waste material is for 10 tons, and the bottom plate 4 of a 3.2 mm thick wear-resistant steel and high-strength steel plate (Domexware) has a predetermined width. The side plates 6 of the rolled steel material for general structure of SS41, which are integrally formed by sequentially pressing the curved corner portions 5 having a radius of curvature of 300 mm on both sides, are integrally joined by welding. The general structural rolled steel is made of 3 to 4 mm having the same thickness as the Swedish steel so that no step is generated in the joint.

  Even though the Swedish steel is thin, it has wear resistance and high tension, but it is expensive. The rolled steel for general structure of SS41 is inferior in wear resistance and high tension compared with Swedish steel, but the price is low, and the corner portion 5 It is easy to mold the curved surface shape, and the cost of the container 1 can be reduced.

  Moreover, as shown in FIGS. 1 to 4, the side plates 6 on both sides of the container 1 are cut into a predetermined size by dividing a single sized steel material into upper and lower plates 7 and 8, respectively. Semi-arc-shaped bending reinforcing portions 9 and 10 bulging outward along the longitudinal direction of the container 1 are provided at the lower portion of the side plate 7 and the upper portion of the lower plate 8, respectively. The bending reinforcing portion 9 and the bending reinforcing portion 10 on the upper side of the lower side plate 8 are overlapped and welded to be integrally joined, and the side portions are reinforced by the bending reinforcing portions 9 and 10 to be economically durable. We make it available with sexuality.

  Therefore, the bottom surface of the container 1 can be lightened and strengthened with wear-resistant, high-strength Swedish steel, and the weight and price can be reduced by 1/3 to 1/2 compared to the conventional one-piece structure. The side part is made of rolled steel for general structure and is divided into parts, and the side part is reinforced by the bending reinforcement parts 9 and 10 to reduce the price and increase the strength. Waste materials such as waste, sludge, and residual soil can be accommodated in the container 1, and the container 1 can be discharged into the transport vehicle so that the waste materials do not stagnate.
