Description

  The present invention relates to an overhead crane with a temporary hopper cart.

  Conventionally, garbage discharged from households and business establishments is collected by garbage trucks (packer cars), transported to a municipal waste incinerator, and in a garbage pit installed at the garbage incinerator. Ceiling that is put in order, grabbing the garbage in this pit by a predetermined amount using an overhead crane with a bucket installed on the garbage pit, and transferring the garbage and putting it into the hopper from inside the pit A crane has been proposed.

  By the way, as for the overhead crane installed so that it can run between the garbage pit such as the conventional garbage incinerator and the incinerator, a plurality of overhead cranes are installed in the garbage pit, including spare ones. Usually, only one overhead crane is used to carry out the transshipment work of garbage and the work of putting it into the hopper of the incinerator from the garbage pit.

For this reason, for example, during the operation of transshipment of garbage, the operation of charging into the other incinerator hopper cannot be performed, so this operation of charging the garbage must be suspended.
Therefore, even if a single overhead crane is used to perform two roles, such as loading into the incinerator hopper and another work such as transshipment of garbage, the work efficiency is performed by a single crane. The work efficiency was low.

  In view of the problems of the above-described conventional overhead incineration crane overhead crane, the present invention can simultaneously perform a transshipment operation of garbage and an input operation into an incinerator hopper with one crane. An object of the present invention is to provide an overhead crane with a temporary hopper cart that can improve the work efficiency.

In order to achieve the above object, an overhead crane with a temporary hopper cart according to the present invention is installed on a girder of an overhead crane, and a club that traverses along the girder, is suspended from the club, and is opened and closed and lifted and lowered. The garbage gripping bucket for carrying out the operation and the club individually traverse along the girder, and are provided with an open / close hopper that receives the dust in the garbage pit from the garbage gripping bucket and can be put into the incinerator hopper It is an overhead crane installed on a garbage pit configured with a temporary hopper cart, and the traversing rail of the club is on the upper surface of the girder and the traversing rail of the temporary hopper cart is on the lower surface of the girder. This arrangement prevents the club and the temporary hopper cart from interfering with each other, and the temporary hopper cart is made up of cylinders on the traverse rail of the temporary hopper cart. Through the device is disposed, the Provisional location hopper carriage, a position to receive the waste from the waste hooking bucket is raised to a position higher than the opening and closing type hopper for the temporary location hopper carriage, a position put into the incinerator hopper It is characterized by reciprocating between the two.

  According to the overhead crane with a temporary hopper cart of the present invention, a single overhead crane can simultaneously serve two roles of waste transshipment and introduction into an incinerator, so that there is relatively little space. Only one overhead crane can be installed on the garbage pit, and the installation can be performed easily, and the operation time cycle of the garbage gripping bucket can be shortened to efficiently perform the crane work.

  Even when it is not possible to immediately put garbage into the incinerator hopper, such as during the work of transferring garbage with the garbage gripping bucket, the waste supplied from the garbage gripping bucket is temporarily stored in the temporary hopper cart. Therefore, if it becomes possible to put it into the incinerator hopper, it can be quickly put in just by opening the open / close hopper, and the garbage gripping bucket can be emptied during that time. The efficiency of the crane can be improved.

  In addition, it is possible to reliably supply the garbage from the garbage gripping bucket and to lower the temporary hopper cart to a position directly above the incinerator hopper when being put into the incinerator hopper. Opening the hopper at the position directly above prevents the waste from rising.

  Furthermore, since the club that suspends and supports the garbage gripping bucket can be reloaded to the temporary hopper cart in the vicinity of the garbage reloading position, it is not necessary to move the club over a long distance from the garbage reloading position. As a result, the operation time cycle of the garbage gripping bucket can be shortened, and the refilling and loading operations of the garbage can be efficiently performed.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of an overhead crane with a temporary hopper cart according to the present invention will be described with reference to the drawings.

1 to 2 show an embodiment of an overhead crane with a temporary hopper cart according to the present invention.
This overhead crane C with a temporary hopper cart is an overhead crane that is installed so as to be able to run on the waste pit P and the waste incinerator B, and traverses along the girder 1 of the overhead crane. A garbage gripping bucket 4 that opens and closes and lifts and lowers is supported on the club 2 via a rope 7 so as to traverse along the girder 1 individually with the club 2. The temporary hopper cart 3 is provided with an openable hopper 5 that receives garbage from the garbage gripping bucket 4 and can traverse and enter the incinerator hopper H.

The girder 1 of the overhead crane C with the temporary hopper cart is allowed to travel along the rail R disposed above the waste pit P and the waste incinerator B, similarly to a normal overhead traveling crane. This is done by driving the traveling wheels W, W arranged at the lower part of the girder 1 with a traveling device (not shown) so that the girder 1 can travel at least over the entire length of the garbage pit. The traveling device is not limited.
Further, the girder 1 is provided with a club traversing rail 6 along its entire length direction, and traverses along the traversing rail 6 at least from the end of the waste pit P to the position above the incinerator hopper H. In this way, the club 2 is arranged.
In this club 2, the garbage gripping bucket 4 is suspended and supported by a rope 7 such as a wire, and the bucket 7 is wound and unwound by a bucket lifting device 21 to recycle the garbage. And the garbage grasping bucket 4 is opened and closed by a rope operation for opening and closing or by hydraulic pressure.
The configuration and opening / closing operation of the garbage gripping bucket 4 are not particularly limited, and a garbage gripping bucket that opens and closes the bucket by a hydraulic method or a rope method can be employed. In the outer lower part of the bucket-type bucket container, it is placed opposite to the left and right, and it has a shape that makes it easy to grab handled items such as garbage, and a shape that can reliably grasp the required amount of garbage, such as city garbage Two bucket pieces projecting a plurality of gripping claws that are easily formed are swingably attached via hinges, and a bucket cylinder is provided on the upper end side of the bucket piece to open and close the bucket piece. It can be configured to perform a grabbing action.

  In addition to the club traverse rail 6, a traverse rail 8 for a temporary hopper cart is laid on the girder 1. Although the height position of the traverse rail 8 and the club traverse rail 6 of the temporary hopper cart is different, this is not particularly limited. For example, the club traverse rail 6 is placed at a high position ( On the upper surface of the girder 1, the traversing rails 8 of the temporary hopper cart 3 are arranged in parallel so as to be in a low position (lower surface of the girder 1), and thereby interference between the club 2 and the temporary hopper cart 3. To prevent.

  The laying position and the length of the traversing rail 8 of the temporary hopper trolley are determined between the position where the temporary hopper trolley 3 receives at least garbage from the garbage gripping bucket 4 and the position where it is put into the incinerator hopper H. The reversible hopper 5 is disposed from the temporary hopper cart 3 in which the garbage received from the garbage gripping bucket 4 has been moved to a position directly above the incinerator hopper H, and the lower part thereof. By opening, it can be directly put into the incinerator hopper H.

Further, the temporary hopper cart 3 that receives the garbage from the garbage gripping bucket 4 is provided with an openable hopper 5 at a lower position thereof, and an elevating device for raising and lowering the temporary hopper cart 3, specifically Is provided with a cylinder. Thereby, from the garbage gripping bucket 4 raised to a higher position than the open / close hopper 5 of the temporary hopper cart 3 , it is possible to receive and temporarily store garbage so as to be stacked on top of the closed open / close hopper 5, At the position on the incinerator hopper H, the temporary hopper cart 3, at least the position of the openable hopper 5 is lowered to the position directly above the incinerator hopper H, and then the openable hopper 5 is opened for incineration. It is possible to prevent scattering at the time of putting garbage into the furnace hopper H.

Next, the operation of transferring waste and putting the waste into the incinerator hopper H using the overhead crane with a temporary hopper cart of the present invention will be described.
When the overhead crane C with a temporary hopper cart placed at a predetermined position of the garbage pit P and capable of traveling is to be transshipped in the garbage pit P, as shown in FIG. , The garbage gripping bucket 4 is opened like a chain line and the rope 7 is unwound and lowered toward the top of the garbage mountain, so that the bucket comes into contact with the top surface of the garbage mountain, that is, the bucket by landing Due to its own weight and its descending speed, the gripping claws protruding from the bucket tip pierce the garbage mountain.

When the rubbing bucket 4 is landed, the rewinding and descending of the rope 7 is stopped, and the bucket piece released (opened) by the action of the hydraulic pump is closed, so that the garbage is separated from the garbage grasping bucket. It will be naturally grabbed inside. By repeating this operation a few times as necessary, it is possible to more reliably grasp the garbage.
Then, while lifting the garbage gripping bucket 4 and moving it to a position where it can be transferred to the temporary hopper cart 3, the garbage gripping bucket 4 is opened, and the dust in the bucket 4 is discharged and transferred. Hereinafter, this operation is repeated.

In addition, when a command for putting garbage into the garbage incinerator B is issued during the transshipment operation in the garbage pit P, the garbage picked up by the garbage grasping bucket 4 is transferred into the temporary hopper cart 3. To do.
This moves the temporary hopper cart 3 to a position immediately below the raised position of the garbage gripping bucket 4, and the temporary hopper cart 3 does not interfere with each other. It is assumed that the carriage 3 is moved up and down by a lifting device.
In this way, the temporary hopper cart 3 that has received the waste is moved (transverse) to the waste incinerator B side, specifically to a position directly above the incinerator hopper H, and then the elevator device is operated to operate the temporary hopper cart. When the openable hopper 5 is opened after the 3 is lowered, the dust temporarily stored in the temporary hopper cart 3 is surely put into the incinerator hopper H without rising.

Temporary hopper cart 3 that has been emptied is placed in a standby state at a garbage entry position, or in a position that does not interfere with the work of transferring garbage in the pit by the garbage gripping bucket 4 and is easy to transfer the garbage from the bucket. However, when the empty temporary hopper cart 3 is put on standby, the hopper of the temporary hopper cart 3 on standby is closed so that the next waste incinerator B can be quickly put into place if there is a command to put in waste. The next supply of garbage can be received from the garbage gripping bucket 4 and can be kept on standby so as to be temporarily stored.
By doing in this way, the garbage bucket 4 can be continuously carried out until the next incinerator is put into the garbage without suspending the operation, and one unit can perform different operations simultaneously. The work efficiency of the overhead crane can be improved by performing the two roles.

In addition, although the operation | movement which transfers the garbage grasped with the bucket 4 for garbage temporarily once in the temporary hopper cart 3 and throws in into the incinerator hopper H was demonstrated, it grasped with the bucket 4 for garbage grasp. It is also possible to put the garbage directly into the incinerator hopper H.
In particular,
(1) In the state where the temporary hopper cart 3 is in the standby state at the right end position in FIG. 1, the garbage gripping bucket 4 is moved to a position directly above the incinerator hopper H, and then the bucket 4 is opened. The waste in 4 is put into the incinerator hopper H.
(2) The width W3 of the temporary hopper cart 3 is formed wider than the width W4 of the garbage gripping bucket 4, and the temporary hopper cart 3 is lowered to a height at which the bucket 4 can pass on the garbage pit P, and the bucket passes through. 4 is moved to a position directly above the incinerator hopper H, the bucket 4 is opened, and the dust in the bucket 4 is put into the incinerator hopper H.
(3) The width W1 of the girder 1 is widened so that the traversing rail 8 of the temporary hopper cart 3 can move in the traveling direction of the overhead crane C, and the garbage gripping bucket 4 passes beside the temporary hopper cart 3. After moving the bucket 4 to a position directly above the incinerator hopper H, the bucket 4 is opened, and the dust in the bucket 4 is put into the incinerator hopper H.
Etc. can be adopted.

  As described above, the overhead crane with a temporary hopper cart according to the present invention has been described based on the embodiment.However, the present invention is not limited to the configuration described in the above embodiment, and may appropriately be used without departing from the scope of the present invention. The configuration can be changed.

  The overhead crane with a temporary hopper cart according to the present invention can simultaneously carry out the transshipment work of garbage and the charging work into the incinerator hopper with one crane, and can improve the work efficiency of the overhead crane. It can be widely used for waste incinerators and other facilities that handle garbage.
