Description

Removing device of fallen coal using excavator

The present invention relates to an apparatus for removing grenade using an excavator, and more particularly, installed in an excavator that moves according to the location of occurrence of coal grenade generated by coal transmission, thereby minimizing inflow of grenade when the coal is removed. The present invention relates to a rock removing device using an excavator that can improve the efficiency of removing the rock.

Thermal power generation accounts for about 60% of Korea's electricity production, more than hydropower or nuclear power. Fuels of domestic thermal power generation include bituminous coal, anthracite coal, internal combustion, LNG-composite, diesel and bunker C oil, among which bituminous coal power plants are responsible for base loads (basically used power) and peak loads with LNG-combined thermal power. It is common to take charge of (power when using the most power).

The advantage of thermal power plant is that its structure is simpler than nuclear power plant, its construction cost and construction time are short, and its thermal efficiency is excellent because it is directly heating the boiler.

Bituminous coal, one of the fuels used in boilers, corresponds to anthracite coal, which contains a large amount of volatile components and burns with flame when burned. Examples of bituminous coal include peat, peat, lignite, bituminous coal, and the like, and are mainly used for power generation due to high calorific value.

There are many ways to transfer coal to a boiler, but the conveyor system using belts is mainly used.

Such a belt conveyor is a device for circulating a belt made of rubber, fabric, wire mesh or steel plate, and placing various transport items on the belt, and continuously transporting the belt conveyor. The belt conveyor is driven by rotating the pulley with a pulley. One belt length can be up to about 2,000m when horizontal, and a device for preventing sagging along the way is also provided.

The belt conveyor is supplied to a generator in a coal-filled low coal yard, and is installed to transport long distances while being exposed to the outdoors. Therefore, the coal loaded on the upper part of the belt conveyor is separated from the belt conveyor under the influence of self vibration and wind, accumulated on the ground, and exposed to the outdoors, and is fixed at the upper part of the belt under wet conditions such as rain and snow when the coal moves. When moving out of the supply position and moving downwards, a grenade was built up to the ground by gravity.

Such a grenade may accumulate on the lower ground where the belt conveyor is installed, and if the height exceeds a certain height, it may come into contact with the belt conveyor driving device or the belt, causing a failure of the belt conveyor, or causing an overload of the belt. Since the coal is itself made of coal material with a low ignition point, it is necessary to continuously remove the rock as it may be ignited by rising temperature or irradiated solar heat.

In general, in order to remove the grenade, during the operation of the belt conveyor, the worker enters the lower part of the belt to remove the grenade by hand, or the excavator is removed using an excavator while the belt conveyor is stopped. When the above-mentioned worker removes the grenade by hand, the work speed is slowed, and there is a problem that the injury occurs in contact with the moving belt.

Recently, a rock removing device for removing a rock is installed and used in an excavator has been developed and used. Such an apparatus for removing a camel using an excavator of the prior art is provided by an excavator in the form of a rack pinion with the bucket moved to a position where the shot is removed from the excavator after being transported by the operation of the excavator to the position where the shots are accumulated on the belt conveyor. It is provided to operate the drive device for driving the bucket to remove the pushing the shell.

In the prior art, the grenade removal device using an excavator is driven by rotating the pinion gear while the bucket is moved to the rocket position removed by the operation of the excavator, while the rack gear moves the bucket in the direction of pushing the grenade and reciprocates in the transverse direction. Work to get rid of the grenade.

However, the rock removing device using the excavator of the prior art has a rack gear and a pinion gear which drive the bucket when moving to remove the rock in the bucket. When moving along the rack gear due to the rotation, there was a problem in that the gear is broken or is out of the range of the tooth coupling coupled.

In addition, there has been a problem that the prior art of removing a grenade using an excavator is required to remove the introduced grenade in a state in which the operation is stopped as the rocket is continuously introduced into the driving device when the grenade is removed. .

In addition, the apparatus for removing a grenade using a conventional excavator converts the power transmitted from the excavator into a rotational force to rotate the pinion gear, and converts the rotated power into a linear reciprocating motion by the rack gear. Is complicated and there is a problem in that power loss is generated during power conversion and the output power is reduced compared to the power supplied.

In addition, since the driving force generated by the pinion gear and the rack gear has to withstand the force that the gear pushes the bucket as the driving force is generated by the pinion gear and the rack gear of the prior art, it is difficult to remove the large-capacity camel. There was a problem.

The present invention has been invented to improve the above problems, the problem to be solved by the present invention, is installed in an excavator that is moved according to the location of the occurrence of coal falling generated when coal is sent to receive the power of the excavator to remove the coal It is provided so that the power acts in the direction to be removed, the removal force can be improved, and to provide a rock removing device that can improve the removal efficiency of the rock while minimizing the influx of the shell during the removal.
