The splitting machine performs the secondary disintegration of large rocks, and has the advantages of high efficiency, low cost, simple operation, and safety and reliability that can not be compared with the traditional methods, and the use effect is good. It is an ideal secondary disintegration device.
The reasonable setting of splitting point splitting point is the key to ensure the quality of work and working efficiency. The following parameters are the key to splitting point setting: 1 whether the bottom hole axis is in the same plane; 2 bottom hole depth; 3 bottom hole spacing .
The specific numerical settings in parameters 2 and 3 mainly depend on the model of the splitter and are affected by the density and strength of the rock. For example, when LC-P40 rock splitter is used to split the granite rock, it usually takes lOO tons of granite to split the l cubic area of ​​granite. If you open a granite stone about 5m long and 2m high, generally set 3 to 4 points.
Bottom hole parameter selection and drilling
1) Bottom hole diameter The bottom hole diameter depends on the rock splitter wedge assembly. The size of the wedge assembly depends on the size of the rock in the site. The rock volume is large. The large-diameter wedge assembly is used. The rock volume is small and small. Diameter wedge assembly. The LC-P40 uses a bottom hole diameter of 42mm.
2) Bottom hole depth Bottom hole depth is mainly determined by the model of the rock splitter, LC-P40 selects the bottom hole depth of 5:00mm.
3) Bottom hole spacing The bottom hole spacing depends on the characteristics of the rock and the model of the rock splitter. The LC-P40 selects the bottom hole spacing of 5:00mm.
4) The direction of drilling of the drilled rock should be perpendicular to the surface where the hole is located. The size of the hole should be compatible with the diameter of the splitter, and the depth of the drilled hole is 2OOmm deeper than the insertion length of the wedge assembly. Cleavage Insert the splitting gun into the hole and adjust the splitting direction as required. The splitting machine used in this project is equipped with three splitting lances. When splitting, three splitting lances should be placed in three holes next to each other, and the wedge direction (cracking direction) The direction should be the same, so that the enthusiasm is concentrated and the splitting effect is better. According to the size and hardness of the rock, it can be considered to use 2 sets (6 splitting guns) to split at the same time, which greatly improves the efficiency of splitting.
Start the pump station, control the reversing valve, make the piston out, chase, after the rock cracks a crack (can also be observed from the pressure gauge, when the pressure rises to a certain value suddenly drops) reversing valve commutation At this time, the wedge moves in the opposite direction. When it is reset, the splitter is rotated by an angle and the above-mentioned splitting process is repeated. This can perform multi-directional splitting in one hole, split the stone into multiple pieces, and reduce the number of holes. The workload.
