Description

The present invention relates to an article transport container in which an upper surface opening that opens upward leaving a peripheral edge on an upper surface of a container body is covered with a canopy so as to be opened and closed.

  Conventionally, as this kind of article transport container, a substantially rectangular canopy that covers the upper surface opening that opens upward leaving a peripheral edge on the upper surface of the substantially rectangular container body in plan view. A lateral end of the container body in the lateral direction is integrally connected to a shaft rotatable around an axis extending in the longitudinal direction of the lateral side of the container body in the longitudinal direction, and One in which this shaft is connected to driving means for rotating the shaft forward and backward is known (see Patent Document 1). And when the axis is rotated forward by the driving means when the canopy is opened, the canopy is rotated around the axis until it falls down along the side surface on one side in the left-right direction of the container body to open the top opening, while the canopy is closed. When the shaft is sometimes rotated in the reverse direction, the canopy is rotated around the shaft to close the upper surface opening.

  By the way, the container main body is hung by a gantry crane or unloaded by an unloading device or the like from a loading platform of a container vehicle, and is installed at an input site where an article is put into the container main body. In that case, when installing the container main body, it is necessary to consider the rotation trajectory of the canopy and install it at the input site where no obstacle exists on the trajectory of the canopy.

  However, when the upper surface opening of the container main body is covered with a single canopy as in the conventional case, when the upper surface opening is opened, the axis extending in the front-rear direction on one side periphery of the container main body in the left-right direction. The rotational trajectory of the canopy rotating around the trajectory draws the trajectory of the left and right dimensions of the canopy with the axis as a fulcrum. For this reason, the rotation trajectory of the canopy occupies a considerably wide range from the position where the upper surface opening of the container body is closed until the container body falls down along the side surface on one side in the left-right direction. In this way, if the rotation trajectory when the canopy is open occupies a fairly wide area, the retreat of obstacles that interfere with the rotation trajectory of the canopy will naturally spread over a wide area, which is very important for the installation site when installing the container body. Requires a lot of space.

  The present invention has been made in view of the above points, and the object of the present invention is to improve the structure of the canopy, drastically change the rotation trajectory when the canopy is opened, and install the container main body space. It is an object of the present invention to provide a goods transport container that can be made very compact.

  In order to achieve the above object, in the present invention, an upper surface opening is formed on the upper surface of a substantially rectangular container body that is elongated in the front-rear direction. It is assumed that the container is covered with an openable and closable canopy, and an article transporting container that allows an article to be put into the container main body through the upper surface opening when the canopy is opened. Furthermore, the canopy is divided into four canopy divided pieces in the front-rear direction, and the front-rear outer end of the front outer canopy divided piece and the rear outer canopy divided piece located on both outer sides in the front-rear direction of the canopy divided pieces. Are connected to the front and rear end shafts that can rotate around the axis extending in the left-right direction, respectively, and are positioned on both inner sides in the front-rear direction of the canopy divided pieces. The front and rear canopy split pieces and the rear inner canopy split piece can be rotated at their outer ends in the front-rear direction via connecting shafts extending in the left-right direction with respect to the front and rear canopy split pieces and the rear outer canopy split piece. To support. The front and rear end shafts are connected to driving means for rotating the both end shafts in both the front and rear direction inside and outside the canopy divided pieces, and the front and rear end shafts are separated from each other by the driving means. When the front and rear canopy divided pieces and the rear outer canopy divided piece are respectively rotated in the front and rear direction outward direction, the front and rear inner canopy divided pieces and the front inner canopy divided piece and the rear inner canopy divided The front and rear inner ends of the front and rear inner canopy divided pieces and the rear inner canopy divided pieces are directed toward the front and rear ends along the left and right edges of the container body while raising the front and rear outer ends of the pieces together with the connecting shaft. It is characterized in that the upper surface opening is opened by guiding.

  In addition, it is preferable that the driving means is individually provided for each of the front and rear end shafts.

  In addition, it is preferable that each of the canopy divided pieces is provided with a pair of left and right locking members for fixing the canopy divided pieces to the periphery of the upper surface opening when the canopy is closed.

  A rear opening that opens rearward leaving a peripheral edge on the rear surface of the container main body, a rear lid that covers the rear opening so as to be openable and closable, and the container main body closer to the inner space of the container main body than the rear lid. Formed on the inner surface of the rear cover and extending toward the center line so as to face the outer edge of the rear lid in a direction along the center line of the rear opening, and on the outer edge of the rear lid A first sealing body that is fixed and seals a first gap between a peripheral edge of the rear opening and the outer edge of the rear lid that face each other in a direction perpendicular to the center line, and is fixed to the extension body. And a second seal body that seals a second gap between the outer edge of the rear lid and the extension body. And the extension body may cover the second seal body as a whole from the inner space side of the container body in the direction along the center line.

  Furthermore, the article may be a waste or contaminated soil.

  In short, the canopy is divided into four canopy divided pieces in the front-rear direction, and the front and rear outer ends of the front outer canopy divided piece and the rear outer canopy divided piece are the front and rear end axes of the container body front and rear end edges. The front and rear canopy split pieces and the rear inner canopy split piece are respectively rotated and connected to the front and rear outer canopy split pieces and the front and rear canopy split pieces and the rear outer canopy split piece via the connecting shaft. The front and rear canopy split pieces and the front and rear canopy split pieces when the front and rear both end axes are separated from each other by the driving means that freely supports and connects the front and rear end axes, Front and rear sides of the front inner canopy divided piece and the rear inner canopy divided piece while raising the front and rear inner ends of the rear outer canopy divided piece and the front and rear inner canopy divided pieces and the rear inner canopy divided piece together with the connecting shaft. And it opens the upper opening to guide the front and rear end edges facing along the right and left end edges of the direction inner end container body.

  Therefore, when the canopy divided piece divided into four pieces opens the upper surface opening, the front and rear canopy divided pieces and the rear outer canopy divided pieces in the front-rear direction inner ends, the front inner canopy divided pieces and the rear inner canopy divided pieces Folding the front-rear outer end of the front and rear ends to the front and rear end edges to open the upper surface opening, and at the front and rear end edges of the upper surface opening, respectively, one canopy split piece upwards the dimension in the front-rear direction. Only the rotation trajectory occupies. As a result, there are no obstacles that interfere with the rotation trajectory of the canopy around the front, rear, left, and right of the container body, so that the obstacles move out little and do not affect the surroundings of the container body. Therefore, the space at the input site where the container body is installed can be made very compact.

  In addition, by providing the driving means for each of the front and rear end shafts separately, there is no need to connect the front and rear end shafts so that power can be transmitted by the connecting shaft. For this reason, when holding waste or contaminated soil with a fork claw or the like and loading it into the container main body from the upper surface opening, considering the shape of the upper surface opening of the container main body, either the left or right side of the upper surface opening or the other A hydraulic excavator provided with a fork claw or the like, even when an article is loaded from the side, without connecting a shaft extending in the front-rear direction on one side edge or the other side edge of the upper surface opening when the article is thrown Usability such as can be improved.

  In addition, each canopy divided piece is firmly fixed to the periphery of the upper surface opening by fixing each canopy divided piece to the periphery of the upper surface opening when the canopy is closed by a pair of left and right locking members of each canopy divided piece. Can be fixed to.

  Further, the first gap between the peripheral edge of the rear opening of the rear surface of the container body and the outer edge of the rear lid is sealed by the first sealing body fixed to the outer edge of the rear lid, and extends from the outer edge of the rear lid. The second gap between the extended body and the extended body is sealed by a second seal body fixed to the extended body formed on the inner surface of the container body on the inner space side of the container body from the rear lid, and the extended body is By extending toward the center line side so as to face the outer edge of the rear lid in a direction along the center line of the opening, the second seal body is entirely covered from the inner space side of the container body. By the 1 seal body and the 2nd seal body, liquids, such as water which exudes from the article in the container main body, are surely prevented from leaking outside the container through the first and second gaps.

  And when an external force is to be applied to the second seal body from the article accommodated in the container body, this external force is mainly carried by the extension body, so that it is directly large from the article to the second seal body. An external force is prevented from acting. Therefore, the second seal body is prevented from being damaged by the external force from the article in the container, and the durability of the container body can be improved.

  Moreover, even when the rear lid is opened and the container main body is tilted rearward so that the articles in the container main body are discharged from the rear opening, the collision of the articles with the second seal body causes the second seal body to be put into the container. It is avoided by the extension body covering from the internal space side of the main body. Therefore, the damage of the second seal body due to the collision of the articles is similarly prevented, which is advantageous in improving the durability of the container body.

  Furthermore, by storing waste and contaminated soil in the container body, it is possible to reliably prevent the exudate water from the waste and contaminated soil from leaking from inside the container body through the top opening. The surroundings can be reliably prevented from being soiled. In addition, it is possible to reliably prevent the waste and contaminated soil in the container body from spilling from the upper surface opening, and to reliably prevent the surroundings of the container body from being contaminated by the waste and contaminated soil. Moreover, it is possible to reliably prevent odor diffusion from the contents in the container body to the outside.
