1 is a schematic schematic view of a loading machine equipped with a sprinkling system for a loading and unloading machine according to an embodiment of the present invention, and FIG. 2 is a schematic perspective view of a foot assembly and an injection part of a spraying system for a loading and unloading machine according to an embodiment of the present invention.

First, with reference to Figures 1 and 2, it will be described with respect to the loading and unloading machine used in the present invention.

The load 10 loaded in the storage 2 of the ship is unloaded through the loading and unloading machine installed in the dock 1.

The loading and unloading machine is formed long in one direction from the main body 110 and the main body 110 moving along the rail installed on the pier 1, and the boom 120, the boom 120 and the weight are installed to be movable or rotated. Counter-waiter boom 130 for hitting the center, a bucket elevator 140 connected to one end of the boom 120 by a bucket elevator support 1230 and formed in a lower direction of the boom 120, and a bucket elevator ( It is disposed on the lower portion of the 140 is provided with a foot assembly 150 for unloading the load (10) using a plurality of buckets (151).

The loading and unloading route of the load using such a loading machine is as follows.

When the ship loaded with the load on the pier 1 docks, the loader is moved by the driving unit 112. The portal 111 is disposed on the driving unit, and the bucket elevator 140 is moved to the storage 2 of the ship by vertically moving or rotating the boom 120 by the boom support 114 disposed on the portal 111. Position it.

The load 10 loaded on the storage 2 of the ship is carried in a bucket 151 connected to the chain 152 of the foot assembly 150. In order to efficiently load the load 10 into the bucket 151, the bucket elevator 140 rotates to adjust the position of the foot assembly 150. The load 10 contained in the bucket 151 is moved to the upper discharge chute 143 through the bucket moving part 141 of the bucket elevator 140. Subsequently, the load 10 unloaded in the discharge chute 143 is dropped onto the boom conveyor 122 disposed on the upper portion of the frame 121 of the boom 120 through the circular transfer chute 144, through which The load 10 is transferred to the central suit 113. The load 10 unloaded to the central chute 113 is transferred to the quay conveyor line 3 disposed at the quay 1 through a belt conveyor 118 installed at the bottom of the central chute 113.

In the process of transporting the load 10, a large amount of scattering dust is generated.

For example, unloading of coal, such as sub-bituminous coal from Russia, has a problem in that unloading is stopped or complaints occur due to a large amount of scattering dust generated during unloading. In particular, scattering dust is generated in the process of excavating the load 10 with the bucket 151.

Accordingly, the sterilizing system for the loading and unloading machine according to an embodiment of the present invention installs the injection unit 240 in the bucket elevator 140 on the top of the foot assembly 150.

The injection unit 240 serves to reduce scattering dust by spraying water to a position where the unloading operation is performed.

The injection unit 240 is provided in the guide tube 241 and the guide tube 241 for spraying the supplied water from the periphery of the foot assembly 150 and a nozzle 242 for spraying water.

In general, the foot assembly 150 is formed long in one direction, and in order to reduce scattering dust, the guide tube 241 may also be formed in an elliptical shape formed long in the direction of the foot assembly 150. In addition, a plurality of nozzles 242 are disposed at a predetermined distance to the guide tube 241, thereby increasing the efficiency of low-cost scattering dust.

In addition, as described above, the bucket elevator 140 rotates to increase the unloading efficiency, thereby adjusting the position of the foot assembly 150. At this time, the guide tube 241 of the sprinkler system for loading and unloading according to an example of the present invention is also fixed to the bucket elevator 140 by the support member 243 so that it can be moved depending on the position of the foot assembly 150. That is, even when the foot assembly 150 moves, water for reducing scattering dust may be sprayed at a position where the unloading operation is always performed.

In addition, a water pressure increasing pump 246 for increasing the water pressure injected by the nozzle 242 may be further disposed in the injection unit 240. The hydraulic boost pump 246 may be disposed between the connecting pipe 253 and the guide pipe 241 for supplying water to the guide pipe 241.

Meanwhile, as mentioned above, the bucket elevator 140 rotates to adjust the position of the foot assembly 150 to increase the unloading efficiency. The rotation of the bucket elevator 140 makes it difficult to supply water required for injection to the injection unit 240.

That is, in general, the water required for injection is supplied using a pipe, but the pipe cannot be installed outside the bucket elevator due to the rotation of the bucket elevator. In addition, the bucket moves inside the bucket elevator, making it difficult to install the pipe.

Accordingly, the sprinkler system for the loading and unloading machine according to an example of the present invention has solved such a structural restriction through the connecting tank 230.

Figure 3 is a schematic perspective view of a connecting tank of the sprinkling system for a loading and unloading system according to an embodiment of the present invention, Figures 4 and 5 are cross-sectional views according to I-I 'of Figure 3, the cross-sectional structure of the connecting tank and the shape of the sealing portion It is for explaining.

Referring to Figures 3 to 5, it will be described with respect to the supply of water to the injection tank 240, the connection tank 230 of the sprinkler system for an unloader according to an embodiment of the present invention.

First, the sprinkler system for an unloading machine according to an embodiment of the present invention receives water from the outside through a supply pipe 252 disposed along the boom 130 and accommodates it in the connection tank 230.

In addition, the connection tank 230 of the sprinkler system for the loading and unloading machine according to an embodiment of the present invention is disposed in a ring shape centering on a bucket elevator on the outside of the bucket moving part 141 of the bucket elevator 140. That is, the connection tank 230 is moved dependent on the rotation of the bucket elevator 140.

 In contrast, the connection pipe 232 for supplying water to the connection tank 230 is independent from the rotation of the bucket elevator 140. That is, the connection pipe 232 is installed on the bucket elevator support 123, and is fixed to be independent of rotation of the bucket elevator 140.

The connection pipe 232 is penetrated into the opening formed in the upper portion of the connection tank 230, and the opening formed in the upper portion of the connection tank 230 is formed in a ring shape that matches the rotation direction of the bucket elevator 140. Therefore, even if the bucket elevator 140 rotates, the connection pipe 232 is maintained in a state penetrated into the connection tank 230.

In conclusion, even if the connection tank 230 rotates with the bucket elevator 140, regardless of this, the connection pipe 232 may supply water for injection to the connection tank 230.

The water accommodated in the connection tank 230 is supplied to the injection unit 240 through the connection pipe 253. Since the connection tank 230, the connection pipe 253, and the injection portion 240 are all dependent on the rotation of the bucket elevator 140, there is no problem in the supply of water in this section.

Meanwhile, a water level sensor 234 is disposed in the connection tank 230, and one valve 235 is disposed at one end of the connection pipe 232. When a level below a certain amount is detected from the water level sensor 234, water may be supplied to the connection tank 230 by controlling the valve 235.

In addition, as shown in FIG. 4, a seal 233 is disposed in the opening of the connection tank 230. In the space where the loading and unloading work is carried out, scattering dust occurs at various locations. When this scattering dust flows into the connection tank 230, it causes a failure, such as blocking the connection pipe 253. The connecting tank 230 of the sprinkling system for the loading and unloading system according to an example of the present invention is arranged by placing the sealing 233 in the opening, so that the sealing is opened only at the place where the connecting pipe 253 is located, and the other position is closed, thereby closing the connecting tank 230 ) To prevent foreign substances from entering. Alternatively, as shown in FIG. 5 instead of the sealing, it is also possible to fix the rubber ring 233 'with a piece on the inside and outside of the opening. The outlet 236 is formed at the bottom of the connection tank 230, and may be used when washing the connection tank 230.

In summary, by using the sprinkling system for the loading and unloading machine according to an example of the present invention, the structural limitations due to the rotation of the bucket elevator 140 are overcome and the water assembly 150 smoothly reduces water scattering. There is an effect that can be sprayed.

However, a separate means is needed to supply water to the handling machine itself. The unloading machine is moved by the driving unit 112 on the rail installed along the pier 1. Conventionally, in order to clean the cargo machine or to supply the necessary water, the cargo machine was moved to a position where water can be supplied.

However, in order to drive the sprinkler system for an unloading machine of the present invention in the unloading process, there is a need for a method capable of supplying the required water regardless of the position of the unloading machine.

6 is a schematic perspective view of a traveling part and a cable chain of a watering system for a loading and unloading machine according to an example of the present invention.

With reference to FIGS. 1 and 6 together, in the sprinkler system for an unloading machine according to an example of the present invention, a method for supplying the required water regardless of the position of the unloading machine will be described.

First, in the sprinkler system for an unloading machine according to an example of the present invention, a water tank 220 may be installed in the main body 110. The water tank 220 is connected to the supply pipe 252 and serves to receive water to be supplied to the sprinkling system according to an example of the present invention.

In addition, the sprinkler system for an unloading machine according to an embodiment of the present invention may include a water supply unit 210 that is formed to be long according to the moving direction of the unloading machine.

The water supply unit 210 includes a cable chain 211 and a water pipe 212 which are disposed in the cable chain 211 that is stretched and contracted according to the movement of the main body 110 of the unloading machine.

The water pipe 212 serves to supply water through the connecting pipe 251 from the outside to the water tank 220.

As can be seen in Figure 6, the cable chain 211 is shortened as part of the cable chain 211 overlaps when the main body 110 of the unloading machine is moved, or the cable chain 211 at the top moves to the bottom. do.

That is, the sprinkler system for the loading and unloading machine according to an example of the present invention does not need to move the loading and unloading machine to a position where water can be supplied for supplying water as in the prior art by supplying water using the cable chain 211. Therefore, the sprinkling system for the loading and unloading machine according to an embodiment of the present invention has an advantage that it can supply the required water regardless of the position of the loading and unloading machine. In particular, the water supply unit 210 may be used to supply various waters, such as supply of washing water and supply of fire fighting water.

The scope of the present invention is not limited to the description and expression of the embodiments explicitly described above. In addition, it is once again pointed out that the scope of the present invention may not be limited by the obvious changes or substitutions in the technical field to which the present invention pertains.
