Non-vibration rock mass cutting device using water pressure and its hydraulic pressure supply device

The present invention is an assembly structure of a supply tube to be supplied with high-pressure water and the expansion tube is mounted on the outer side of the supply tube and expanded and restored while having a spacing member and a guide tube mounted on the outer side of the expansion tube to maintain pressure It relates to a vibration-free rock cutting device using the pressure of water to inflate rock without vibration while the expansion tube and the guide tube expand at the same time.

In addition, the present invention is a vibration-free rock-breaker installed when the pressure of the fluid is supplied to the second chamber having a relatively narrow area when the fluid is supplied to the first chamber having a relatively large area to double the pressure It relates to a hydraulic pressure supply device.

In general, a method of crushing a rock has been used to form a blast hole and to crush it by charging gunpowder inside it, or to manually crush it manually using a tablet according to the characteristics or texture of the rock.

When using gunpowder, first, a plurality of blasting holes are drilled in the rock at appropriate intervals, and then the gunpowder is inserted into the blasting, and when the blasting is performed, the rock is crushed by the pressure of the gunpowder generated inside the blasting hole.

However, the use of gunpowder has the advantage that it can be easily crushed even large rock, but the explosion noise is high, the risk of safety accidents at work is also very high, and it is not possible to perform work unless you are an expert, so in terms of environmental, stability and workability Problems and regulations followed.

In order to solve such a problem, a cylindrical crusher is presented in Korean Laid-Open Patent Publication No. 95-23831, the configuration of which is to operate a number of small cylinders provided on the side of the body to apply a force to the rock For example, when the strength of the rock is not constant, excessive force is applied to the cylinder, which causes frequent breakage, and only one side of the force is applied, thereby preventing effective crushing.

In addition, in order to solve the above problems, the Korean Utility Model Publication No. 1998-20574 discloses a rock crushing ball and its configuration, as shown in Figures 1 and 2, the rock crushing ball 100 is generally cylindrical A circular tube 10 forming a central axis, an elastic tube 20 expanded by oil injection while surrounding the circular tube 10, and an upper end of the circular tube 10 prevent oil from being separated from the capping 50. Cap-shaped nut 30 provided with a hose connection tab 31, the lower end is made of a configuration that the cap-shaped nut 30 for preventing the separation of the cap ring 50 is screwed.

In addition, the circular pipe 10 forming the central axis is provided with a thread 12 at both ends thereof while a plurality of oil supply holes 11 are drilled, and the oil supply hole 11 is connected to the circular tube 10 from the outside. The inflow oil is supplied to the elastic tube, the cap ring 50 is provided with a through hole and the same inside and the same as the outer diameter of the circular tube 10, the upper and lower parts of the circular tube 10 through the through hole When each is inserted in the elastic tube 20 as the concave-convex portion 21 is fixed to the circular tube (10).

In addition, the cap nut 30 is provided with an oil hose connecting tab 31 and a thread 12 connected to an external oil hose, and the cap nut 30 is a screw thread provided at the upper end of the circular tube 10. Screwed with 12 to supply the oil from the outside to the circular tube 10 while preventing the capping 50 from being separated from the circular tube 10 when the elastic tube 20 is expanded.

However, the rock crushing sphere as described above, the elastic tube 20 by supporting the elastic tube only through the latching jaw formed in the cap ring 50 so that the coupling portion is easily separated when the pressure acts on the elastic tube 20 to leak the pressure. There is a problem that can not be expanded, the moment there is no change in the diameter of the cap ring 50 when the rock is incision, so that the gap between the elastic tube and the elastic tube 20 is easily concentrated due to the pressure of the elastic tube 20. .

When the rock crushing hole is inserted into the blast hole, the elastic tube 20 expanded through the gap formed by the blast hole and the cap ring 50 is exposed so that pressure is not accurately transmitted to the inside of the blast hole, and the elastic tube 20 is exposed. When the expansion of the capping 50 is not expanded at the same time because the elastic tube is exposed to the gap between the capping and the drilling hole has the disadvantage that it is difficult to accurately transfer the pressure.

In addition, the elastic tube 20 is swelled only in the gap, so as to be easily broken, thereby reducing the reliability of the elastic tube 20.

On the other hand, when the thickness of the elastic tube 20 is increased in order to solve the above problems, the thickness of the uneven portion 21 is relatively reduced, so that the pressure is concentrated, thereby increasing the fatigue of a part and shortening the life.

In addition, a hydraulic piston type vibration-free noiseless rock cutting method has been proposed, and its configuration is inserted into a rock injector hydraulically operated in a hole (Hole) drilled in the rock, and when the operating oil is supplied to the rock cutting machine, the piston is raised and lowered.

In addition, the supply line of the bidirectional switching valve 850 is connected to the first chamber 1315 having a relatively large volume while being divided through the piston 1310 to supply oil compressed to the first chamber 1315 at high pressure. Done.

At this time, the oil pressure OW supplied to the first chamber 1315 is transferred to the second chamber 1317 having a relatively small volume by the principle of Pascal, thereby doubling the pressure so that a simple booster is not required. The configuration allows the pressure to be doubled inside the cylinder.

Then, the second chamber 1317 is filled with water having a predetermined pressure to double the pressure of the water supplied to the rock cutout S by the pressure of the oil opened in the first chamber 1315.

In addition, the return line provided in the oil tank 800 is also provided with a cooler 805 and a return filter 803 to remove foreign substances in the oil while cooling the return oil, the temperature of which rises by continuous compression during pressure increase, and then oil Return to tank.

Subsequently, the water supplied as the water pump 1110 is continuously supplied with the required amount while the return is prevented through the second valve 1107.

In addition, the water supplied as the water pump is continuously supplied to the required amount while the return is prevented through the second valve 1107, and water is leaked when the pressure difference is generated by the second pressure gauge 1530. In operation, the operation of the water pump 1110 is stopped.

In addition, the water tank 1100 is also provided with a water pressure increasing means 1500 to increase the pressure to the desired pressure while recycling the water to supply to the second chamber (1317).

In addition, one side of the rock incision (S) is provided with a drain valve 1320 to disassemble the rock and then to drain the water from the rock incision in order to shrink the rock incision (S) to the water tank 1100 Make it easy to drain.

In addition, the rock cutting machine (S) is to supply the water having a predetermined pressure as each individual cylinder 1300 to prevent the phenomenon that the supply of water to the whole even if the rock cutting machine (S) is damaged. .

The present invention is a supply tube for supplying the water of high pressure and the expansion tube which is mounted on the outside of the supply pipe is expanded and restored while the expansion tube for applying pressure to the drilling hole is firmly supported by a fixed block The present invention relates to a non-vibrating rock cutting device using water pressure to inject rock without vibration so that a uniform water pressure acts on the entire hole when supplying water pressure.
