Description

Multi-Functional Special Equipment for Gathering and Disposing of Coal in Hatch of Coal Transport Ship}

The present invention relates to special equipment for handling onboard coal and xanthan coal. More specifically, in the ship collecting and xanthan coal processing equipment, the upper rotating body and the lower running body is provided, the upper rotating body is provided with an excavation part, a sweeper part and a crane part, and the lower traveling body is provided with a dozer part, The present invention relates to a special equipment for inboard coal collecting and xanthan processing which is injected into a hatch to effectively carry out coal collecting and xanthan processing, and which can be remotely controlled by a remote control device.

In coal-fired power plants, coal and heavy oil are generally used as fuels for power generation. On the other hand, the thermal power plant is mainly located on the coast in order to facilitate fuel transport and to facilitate the intake of water, such as cooling water. In the case of coal-fired power plants, coal is transported by sea to coal carriers, and the coal is transported through a dedicated pier built adjacent to the power plant.

FIG. 1A is a view showing an example of a work for unloading coal of a coal carrier using a continuous ship unloader (CSU).

The coal carrier 110 typically loads and transports coal into nine or more hatches (Hatch 120). The operation of unloading the coal loaded on the coal carrier 110 is called CSU (Continuous Ship Unloader: 100). Through a continuous unloading device. Coal loaded on the coal carrier 110 is transferred to a conveyor belt (Conveyor Belt (not shown)) through the CSU (100), coal is transported to the low coal by the conveyor belt.

As shown in FIG. 1A, when one ship of the coal carrier 110 is docked at the pier, the coal is unloaded by using two CSUs 100. In order to maintain the balance of the coal carrier 110, each CSU ( 100 is to sequentially unload the coal in the direction of the inner hatch 120 from the outer hatch (120).

Figure 1b is a view for explaining the operation of unloading the coal loaded on the coal carrier to the conveyor belt through the CSU.

Coal of the coal carrier 110 is lifted up through the screw 130 provided in the CSU (100) and transported to the outlet 140 is connected to the conveyor belt.

On the other hand, the work of unloading the coal of the coal carrier 110 to the conveyor belt through the CSU 100 can be largely divided into three stages.

In the first step, the coal loaded in the hatch 120 of the coal carrier 110 is unloaded using only the CSU 100. After the coal in the hatch 120 is unloaded to some extent, for example, if the coal remains at a height of about 2 to 3 meters (m) at the bottom of the hatch 120, it is difficult to unload the coal with the CSU 100 alone, and Equipment should be loaded for coal unloading.

Therefore, in step 2, equipment for carrying out operations such as lifting, lifting, and discharging, such as a shovel truck or payloader, is input to assist the coal unloading operation of the CSU 100. That is, after the considerable amount of coal is unloaded, payloader is put into the hatch 120 to collect the remaining xanthan coal near the screw 130 so as to be easily unloaded from the CSU 100.

When the coal remains at a height of about 1 to 2 meters based on the bottom of the hatch 120, a three-stage operation is performed. In the third step, the CSU 100 is withdrawn from the hatch 120 and a working worker is put into the hatch 120 to clean the inside of the hatch after discharging the remaining coal to the outside through the work of the payloader and the working worker. Do the work.

Table 1 shows these unloading operations.

Work steps Unloading means Stage 1 CSU 2 steps CSU + Payloader 3 steps Payloader + worker

The one-stage unloading operation using the CSU 100 is convenient because the CSU 100 can be adjusted wirelessly or by wire, but the two-stage and three-stage operations require a working worker for payloader operation and final xanthan treatment. In the hatch 120, there is a problem that the working environment is very poor due to coal dust and noise.

In addition, in the three-stage operation, the work worker is put together with the payloader to finish the unloading work, so the work worker has a high risk of injury. In particular, since the thermal power plant is continuously operated for 24 hours, the coal unloading operation may need to be performed even at night, and thus there is a problem in that a possibility of a safety accident may exist due to increased fatigue of a worker due to night work.

However, in order to solve these problems, special equipment for inboard coal collecting and xanthan coal processing has not been developed yet. That is, there is no development of equipment capable of processing the coal residues of the hatch 120 in the vessel without input of a workman as well as a simple function of lifting, lifting, and discharging the payloader.

In addition, since the working environment in the ship hatch 120 is poor, such equipment should not only be able to be remotely operated, but also in some cases, the equipment operator should be able to ride and operate. It is not a reality.

On the other hand, if you look at the current state of the automation related technology of large machinery among the industrial control system, the active research and development is progressing in universities and research institutes, but these devices are mainly in the stationary robot or building automation field or humanoid robot field for the automobile factory It is focused on the development of

However, in the case of remote control, the remote control device 800 can be used to operate the special equipment for inboard collecting and xanthan coal processing according to the present invention outside the hatch 120.

The operation of each function part will be explained by dividing it into manual control and remote control. As described above, the operation of each functional part is controlled by the hydraulic circuit shown in Fig. 7, so that both manual control and remote control are made by adjusting the opening and closing of the hydraulic valve.

Hydraulic valves are usually required to supply a large amount of pressure when hydraulic pressure is used to transfer large forces, such as heavy equipment, such as heavy equipment. However, there is a limit to manually opening and closing such pressure or flow hydraulic valves. There is. Therefore, opening and closing of the hydraulic valve generally uses a pilot control method. The pilot pressure refers to the use of hydraulic pressure as a signal for opening and closing the valve. A pilot control method is a method of controlling opening and closing of a hydraulic valve by manipulating a pilot line to which pilot pressure is applied. Pilot control makes it easier to operate the machine because it allows you to control larger forces with smaller forces. Therefore, when manually manipulating the special equipment of the present invention, the driver inside the cabin 260 controls the equipment by using a driving lever installed in the cabin 260.

However, this operation is difficult in the case of remote control.

In the case of remote control of the equipment, it is desirable to use an Electric Proportional Control Valve.

Typically, the electronic proportional control valve refers to a valve that can be controlled in proportion to an electrical signal. In the case of the solenoid valve, the solenoid may be used to directly control the opening and closing of the valve. However, as in the case of manual operation, a large capacity solenoid must be used to directly control the opening and closing of the valve. Therefore, the pilot pressure, that is, the pilot line, is adjusted by the electromagnetic proportional control valve to adjust the opening and closing of the valve.

In a preferred embodiment of the present invention, in the case of remote control of the special equipment for inboard coal collecting and xanthan coal processing according to the present invention, the operation of the hydraulic circuit is controlled by adjusting the pilot line using an electronic proportional control valve.
