Description

[0001] The present invention relates to a method for loading and unloading a continuous ship unloader,

The present invention relates to a method for unloading dust by using a continuous unloading machine, and more particularly, to a continuous unloading (CSU) method for continuously discharging dust coal loaded in a carrier The present invention relates to a method for unloading dust by using an unloading machine.

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.

A continuous type unloading machine used for unloading bituminous coal is composed of a main body moving along a rail provided at a wharf, a boom installed at an upper portion of the main body, and an elevator post vertically installed at the tip of the boom, And an unloading foot for moving a plurality of buckets. Such a continuous type unloading machine has been previously filed as a patent application No. 10-2013-0059886.

First, when the carrier carrying the bituminous coal arrives at the unloading dock, the unloading foot of the driven continuous unloading unit is moved into a hold (hereinafter referred to as 'storage') in which the bituminous coal is loaded on the carrier. And the unloading of the bituminous coal is performed by continuously rotating the bucket provided at the unloading foot. The bituminous coal that is unloaded in this way is conveyed to the low-freeness through the conveyor belt.

However, in the process of unloading the bituminous coal in the confined space inside the storage, the unloading foot often hits the wall inside the storage. In this case, the bucket may be damaged and the unloading operation must be stopped in order to repair the damaged bucket.

In addition, the unloading operation using the continuous unloading machine has a great difference in the operation time required for the unloading of the bituminous coal according to the skill level of the operator. Since the time difference is directly related to the cost of the quarry, it is necessary to increase the efficiency of the unloading operation within a limited time.

Hereinafter, a method for unloading dust using a continuous unloading machine according to the present invention will be described. For reference, the illustration of the collision avoiding unit 200 and the jetting unit 300 will be omitted in order to explain focusing on the dusting and unloading process.

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 the casing 120, which is the center axis of rotation of the unloading foot 130, is inserted into the corner of the opening 3, the loading foot 130 is rotated at a predetermined angle, and the upper part of the dust- 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 dust buried in the central portion 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 to 90 ° or less, and the unloading foot 130 is moved from 80 to 100 cm (the height of the 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 loading and unloading work of the dust gun 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.

In this case, water is continuously injected toward the inside of the reservoir 1 through the spraying part 300 (see FIG. 4) provided in the opening part 3 so as to suppress dust generated during the unloading operation of the dust shot (Step 5).

Referring to FIG. 12, when the inner wall of the fore and aft sides is exposed through the unloading process (steps 4 and 5), the center of rotation of the unloading foot 130 is positioned at the center of the storage 1, ) (Step 6).

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 dust in the storage 1 is biased in one direction, It can affect balance.

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 40 to 60 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 dust buried in the bucket 131 is small, which may lower the unloading efficiency.

13, the unloading operation is carried out while the height (h) of 1.5 to 2 m is maintained so as to prevent collapse of dust buried on the inner wall of the reservoir 1 during the unloading operation (sixth step) Step 7).

After repeating the above-mentioned steps 5 to 7, the cargo loading operation using the unloader is performed until the loaded dust particles remain on the floor surface at least 10 cm or less. Then, as shown in FIG. 14, The dust charcoal is removed (Step 8). In this case, the worker can remove the dust dust by using a long rod such as bamboo or the like, and the portion where the rod is not exposed 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 dust particles remaining on the floor surface at the central portion, and finishing unloading using the unloading foot (Step 9).

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.
