Description

Continuous Unloading Device {CONTINUOUS SHIP UNLOADER}

The present invention relates to a continuous unloading device, and more particularly to a continuous unloading device for unloading vessel loads, such as raw materials, fuel, etc. used in the operation of the blast furnace of the steel mill.

Iron ore and coal, which are used as raw materials or fuels when operating blast furnaces in steel mills, are usually transported to ships, unloaded at docks, and then transported to the yard of the factory through transport equipment such as belt conveyors.

As such, a facility for unloading loads from a ship is called an unloader. In particular, a unloading device in which a bucket excavates a load continuously in an elevator type is called a continuous unloading device.

In general, the continuous unloading device includes a traveling part moving along a pier, a boom installed on an upper side of the running part, an elevator post provided on the boom, and a plurality of moving parts in an orbit along the elevator post. It has a form including a bucket.

According to this continuous unloading device, a plurality of buckets installed in the elevator post is moved along the elevator post to continuously enter the hold of the vessel in which the iron ore or load is stored to excavate and load the load.

The loads disbursed in this way are put into a hopper above the running part along the belt conveyor installed on the boom, and disbursed to a corresponding position through a plurality of belt conveyors associated with the hopper.

The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.

According to the continuous loading and unloading device as described above, as the remaining amount of the load in the hold decreases, the load is not properly contained in the bucket for carrying out the excavation work and is pushed by the bucket, thereby lowering the unloading efficiency.

Therefore, there is a need for improvement.

The present invention was devised to improve the above problems, and an object thereof is to provide a continuous unloading device having an improved structure to improve the unloading efficiency.

Continuous unloading device according to the present invention comprises: a frame portion in which the first rotating portion is installed; A shuttle unit provided with a second rotating unit and movable to the frame unit; A moving part installed on the first rotating part and the second rotating part and moving along the infinite track; And a bucket part installed in the moving part.

In addition, the present invention preferably further includes a load inducing unit linked with the shuttle to guide the loading of the load on the bucket portion.

In addition, the load guide portion, the load guide member for moving up and down in conjunction with the distance between the first rotary part and the second rotary part; And a wire part installed between the shuttle part and the load guide member to control an operation of the load guide member.

In addition, the present invention includes a first guide member provided in the frame portion; And a second guide member provided in the loading guide member to be slidably coupled to the first guide member.

In addition, one of the first guide member and the second guide member is preferably provided with a guide rail, the other is provided with a guide groove into which the guide rail is inserted.

The frame unit may further include: a shuttle frame in which the shuttle unit is movable; And a support frame extending to the upper side of the shuttle frame, wherein the first rotating part is installed on at least one of the shuttle frame and the support frame.

3 and 4 are views showing the operation relationship of the continuous unloading device shown in FIG.

3 and 4, the operation and effects of the continuous unloading apparatus of the present embodiment will be described.

First, referring to FIG. 3, the first rotating unit 160 and the second rotating unit 170 are rotated to unload a load by using the continuous unloading device, and together with the first rotating unit 160 and the second rotating unit ( The moving unit 130 installed at 170 is moved along the caterpillar.

By moving the moving unit 130, the plurality of bucket unit 140 is moved along the orbit along with the moving unit 130 to sequentially excavate and load the load loaded on the hold of the vessel.

Specifically, the plurality of buckets 140 is moved along the orbit along with the moving unit 130, the opening portion 142 in the portion to move the lower portion of the shuttle 120 and shuttle frame 112, Is moved in the horizontal direction to face the second rotating portion 170 and the loading guide member 152 to excavate and load the load.

If unloading of the load continues to reduce the remaining amount of the load, it may not be properly contained in the bucket portion 140 to perform the excavation work may be pushed by the bucket portion 140, the bottom surface on which the load is loaded, for example For example, breakage of the bottom surface of the vessel hold and the bucket portion 140 may occur due to the contact between the bottom surface of the vessel hold and the bucket portion 140.

According to the continuous unloading device 100 of the present embodiment, as shown in FIG. 4, the shuttle part 120 may be moved in a direction in which the first and second rotating parts 160 and 170 are closer to each other. .

When the shuttle unit 120 is moved in this way, the tension of the moving unit 130 installed in the first rotating unit 160 and the second rotating unit 170 is weakened, the moving unit 130 is loosened, the bucket unit 140 is struck in the downward direction with the loosened moving part 130.

As such, the bucket part 140 struck in the lower direction can more effectively excavate a load having a smaller residual amount, and impact the bottom surface of the ship hold due to the loosened moving part 130 even when contacted with the bottom surface of the ship hold. Less is given and the bucket portion 140 itself is also relatively less impacted.

That is, in the continuous loading and unloading device 100 of the present embodiment, when the remaining amount of the load becomes small, the shuttle portion 120 is moved in a direction in which the first rotating portion 160 and the second rotating portion 170 come closer to each other. It is possible to further improve the unloading efficiency when the remaining amount is small, and to suppress the occurrence of breakage of the bottom surface of the ship holder and the bucket portion 140.

On the other hand, when the shuttle unit 120 is moved in the direction in which the first rotary unit 160 and the second rotary unit 170 closer as described above, the wire unit provided between the shuttle unit 120 and the loading guide member 152. The 154 moves along the shuttle portion 120 in a direction approaching the second rotating portion 170, and the loading guide member 152 moves the lower portion of the frame portion 110 by the movement of the wire portion 154. Descend toward.

The lower load inducing member 152 is not loaded on the bucket part 140 at the lower portion of the frame part 110, but the load pushed out of the bucket part 140 is no longer pushed to the outside of the load inducing member 152. By blocking the path from which the load is pushed out so as not to go, it induces loading of the load.

Continuous loading and unloading device 100 of the present embodiment as described above, the load of the load by blocking the movement path of the load that is pushed by the bucket portion 140, not loaded in the bucket portion 140, Even if the remaining amount is small, it is possible to effectively carry out the excavation and loading of the load to improve the unloading efficiency.

In addition, if the remaining amount of the load is small, by moving the shuttle 120 in the direction of the first rotation unit 160 and the second rotation unit 170 closer, the unloading efficiency when the remaining amount of the load is further improved At the same time, breakage of the bottom surface of the ship holder and the bucket portion 140 can be suppressed.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. I will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims below.
