Generally, bituminous coal used as a heat source in a power plant is a kind of coal, which is transported by a carrier and then unloaded from a quay through a continuous cargo ship. Bituminous coal is subdivided into standard coal and dust coal depending on whether water is contained or not. Specified carbon contains a certain amount of moisture, and dust generation is small when unloading. Since the amount of water contained in the dust charcoal is small, dust can be generated relatively easily compared to the standard charcoal when unloading.

1, a continuous type unloading machine according to the present invention includes a main body 100 installed to be movable along a rail 10 installed at an unloading dock, a boom 100 installed at an upper portion of the main body 100, A casing 120 installed in the casing 120 and provided at a front end of the boom 110 so as to be able to lift a bituminous coal loaded in the storage 1 of the ship, Shaped loading and unloading foot 130 provided with a bucket 131 rotatably installed in an endless track manner.

2, the lower end of the unloading foot 130 may prevent the inner wall of the storage 1 from colliding with the bucket 131 during the unloading operation, or may prevent the bucket 131 from colliding with the inner wall when the front end of the unloading foot 130 collides with the inner wall. The collision avoidance unit 200 can mitigate an impact applied to the vehicle. Preferably, the collision avoidance unit 200 includes a frame 210 installed at both ends of a center axis of the bucket drive sprocket 133 so as to surround the front end of the load foot 130, 210 may include at least one rotating roller 220 that is rotatably mounted. The rotary roller 220 may be installed to be rotatable about a vertical axis provided on the frame 210 or may be rotatable about a horizontal axis.

3, the rotating roller 220 is rotatably coupled to the stationary bracket 221 and the stationary bracket 221 is slidably coupled to the frame 210 via the buffer spring 223, It is possible to alleviate the impact generated.

Referring to FIG. 4, on the frame 210 at the front end of the unloading foot 130, high-pressure water is sprayed toward the inner wall of the reservoir 1 to remove the hardened bituminous coal. And a yarn 300 may be provided. That is, bituminous coal (standard coal) loaded in the storage 1 contains moisture and is often fixed to the inner wall. Accordingly, the jetting unit 300 or the worker manually removes the bituminous coal fixed by hand.

5, the jetting unit 300 includes a swinging shaft 320 rotatably coupled to the frame 210 and coupled to the plurality of jetting nozzles 310 along the longitudinal direction, And a driving cylinder 330 installed at one side of the swinging shaft 320 for swinging the injection nozzle 310 up and down within a range of 30 to 90 degrees. The driving cylinder 330 may be operated in various manners in which one of hydraulic pressure, pneumatic pressure and electricity is supplied.

Referring to FIG. 6, the jetting section 300 having such a structure injects water supplied through the jetting nozzle 310 at a high pressure. When the jetting nozzle 310 is moved up and down by the operation of the driving cylinder 330 As you swing, you can spray high-pressure water like scattering.

In this case, in the present invention, the spray nozzle 310 is shown as an example of swinging up and down. However, the present invention is not limited thereto, and the spray nozzle 310 may be used while being fixed at a predetermined angle. Of course, it can be used in various ways.

In addition to the purpose of removing the hardened bituminous coal, the jetting unit 300 can also be used for minimizing the generation of dust during the unloading operation of the dust charcoal (the content of moisture is smaller than that of the standard charcoal). That is, dust is inevitably generated during the unloading operation of the dust charcoal using the unloading foot 130. Therefore, by spraying water toward the dust generation site using the sprayer 300, generation of dust can be minimized.

In the present invention, the collision preventing part 200 and the jetting part 300 are selectively provided on the frame 210. However, the present invention is not limited to this, Of course, it can be used.

Hereinafter, a method for unloading a bituminous coal using the continuous unloading machine according to the present invention having the above-described structure will be described. For reference, the illustration of the collision avoiding unit 200 and the jetting unit 300 will be omitted for the sake of illustrating the process of unloading the bituminous coal.

First, the operator preliminarily grasps the depth of the reservoir 1, the internal protruding part, and the arrangement structure of various structures provided in the carrier (step 1).

Referring to Fig. 7, all the carriers are formed so that the internal structures of the reservoirs 1 are different from each other. Therefore, it is necessary to grasp the structures such as the ladder in the storage 1 of the cargo ship, the protruding part of the pipe and the like, and the shape of the reservoir 1 provided at the bow and stern. Thus, the unloading delay due to the collision between the unloading foot 130 and the structure during the unloading operation can be prevented. Also, since the depth of the reservoir 1 is known in advance, it is possible to prevent the loading foot 130 from colliding with the bottom at the loading and unloading finishing step.

8, when the structure of the reservoir 1 is grasped, the operator can grasp the boom 110 on a rectangular shaped opening 3 having a narrow opening width on the upper side, Are arranged diagonally. Then, the boom 110 and the unloading foot 130 are aligned in a straight line (second step).

That is, when the angle between the boom 110 and the unloading foot 130 is large, the flow of the unloader occurs a lot, which causes the excavation efficiency of the bucket 131 to be lowered. Therefore, it is preferable to match the boom 110 and the unloading foot 130 when the loading foot 130 is lowered into the reservoir 1 to start the excavation work.

After inserting the casing 120, which is the rotation center axis of the unloading foot 130, at the corner of the opening 3, the loading foot 130 is turned at a predetermined angle and the upper part of the bituminous coal filled in is excavated Thereby securing a work space capable of turning the unloading foot 130 in the storage 1 (third step).

Referring to FIG. 9, the center of rotation of the unloading foot 130 is disposed at any one of the four corners of the opening 3 to start the unloading operation of the bituminous coal loaded in the center of the storage 1. When the unloading operation of the depth of 1 ~ 2m is completed at the corresponding point, the rotating center of the unloading foot 130 is moved to the remaining points and the unloading operation is performed sequentially.

In this case, the turning radius of the unloading foot 130 is set within 90 degrees, and the unloading foot 130 is moved 40 to 60 cm (the height of the opened bucket is about 100 cm when excavated) repeatedly up and down (Luffing down ) It is desirable to perform the unloading operation. That is, as the rotation of the unloading foot 130 is shortened at a narrow interval, the bucket 131 can be further inserted and operated, thereby improving the unloading efficiency.

It is preferable that the unloading foot 130 is turned clockwise from the first left side when viewed from any one side of the four sides of the opening portion 3 where the operator is located.

10, when the work space of the unloading foot 130 is secured in the reservoir 1, the unloading foot 130 is lowered into the reservoir 1 under the opening 3, and then the unloading foot 130 ) To carry out the unloading of bituminous coal in earnest (Step 4). When the unloading foot 130 descends, the boom 110 and the unloading foot 130 must be aligned in a straight line.

11, after the unloading foot 130 is lowered into the reservoir 1, the boom 110 and the unloading foot 130 are aligned in a straight line from the unloading foot 130 at a reference (0 °) Of the turning radius within 180 ° in clockwise direction and 180 ° in counterclockwise direction.

12, when the inner wall of the fore and aft side is exposed through the unloading process (the fourth step), the center of rotation of the unloading foot 130 is positioned at the center of the storage 1, and the unloading foot 130 And the unloading operation is carried out (Step 5).

That is, when the loading operation is continued without confirming the center of the storage 1, the center is continuously changed as the boom 110 is lowered due to the structure of the loader. As the bituminous coal in the storage 1 is biased in one direction, . ≪ / RTI >

In this case, it is preferable that the turning radius of the unloading foot 130 is within 360 °, and the unloading operation is performed by moving the unloading foot 130 by 20 to 30 cm up and down repeatedly. That is, when the vertical movement distance of the unloading foot 130 is 30 cm or more, the overloading may cause the unloader to stop. Conversely, when the up-and-down moving distance is 20 cm or less, the amount of bituminous coal contained in the bucket 131 is small and the unloading efficiency may be reduced.

13, the unloading operation is carried out while maintaining the height h of 1.5 to 2 m so as to prevent the bituminous coal loaded on the inner wall of the reservoir 1 from being collapsed during the unloading operation (fifth step) Step 6).

After the above steps 5 and 6 are repeatedly performed, the unloading operation is performed using the unloader until the loaded bituminous coal remains on the floor surface at least 10 cm or less. Then, as shown in FIG. 14, (Step 7). In this case, the bituminous coal removing work can be removed by a worker using a long pole such as bamboo, and the uncoated portion can be removed using the sprayer 300 according to the present invention.

Finally, as shown in FIG. 15, the excavator is charged into the reservoir 1 to collect the bituminous coal remaining on the bottom surface, and the finished bit is unloaded using the unloading foot (Step 8).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
For example, in the present invention, the frame 210 is coupled to the front end of the loading foot 130 so that both ends of the frame 210 are fixed to the center axis of the bucket driving sprocket 133, The jetting unit 300 may be installed on the frame 210 along the longitudinal direction of the swinging shaft 320 to separate the plurality of jetting nozzles 310 from each other.
Therefore, when the front end of the unloading foot 130 collides with the inner wall of the reservoir 1 through the collision preventing part 200 during the unloading operation, the shock applied to the bucket 131 can be alleviated, Water is jetted toward the bituminous coal fixed to the inner wall of the reservoir 1 through the jetting unit 300 in a state in which the tip of the unloading foot 130 is brought into close contact with the inner wall of the reservoir 1 as much as possible, By doing so, it is possible to remove bituminous coal adhered with strong water pressure.
