Description

Technical Field

[0001] The utility model relates to the technical field of mining engineering auxiliary equipment, in particular to a drill rod holding and processing device for a raise boring machine in a mining area. Background Art

[0002] In the construction of mine development projects, most of the current chute and ventilation shaft construction uses mechanical equipment instead of manual excavation. While mechanical equipment improves the construction safety factor and construction progress, it also has some fatal shortcomings. For example, when the chute and ventilation shaft excavation equipment (raised borer) encounters areas with poor geological conditions during the guide hole process, it is easy to cause the borehole to collapse, the borehole to return water abnormally, and the guide hole waste residue cannot be discharged out of the hole. If not handled carefully, the raise hole drill rod will be stuck and the drill will be stuck. Once the raise hole drill rod is stuck and the drill rod is stuck, the construction drill can no longer be constructed, and the drill rod cannot be removed, which will result in a series of chain economic losses such as the drill rod being discarded, the design changed, and the chamber being re-excavated.

[0003] Therefore, in the construction of mine development projects, when encountering this problem, in order to solve the blockage of the drill rod of the drilling rig, there is an urgent need for a more efficient, safer and economically feasible processing device. Utility Model Content

Explosives are loaded for blasting at a distance of 5m-10m from the hole mouth, and the borehole mouth is filled with gun mud. A handheld detonator is used at the cave mouth to detonate the electronic digital detonator for blasting, and the guide hole drill rod is vibrated to loosen the crack between the guide hole drill rod and the rock wall. The drill holding state is released under the flushing of high-pressure water flow in the borehole, so that the guide hole drill rod can rotate freely, and finally the purpose of dealing with the drill holding of the raise drilling rig drill rod is achieved. The operation is safe and reliable, the investment is small, the treatment period is short, the well drilling position and the shaft forming are not changed, and the economic impact caused by the blockage and drill holding of the raise drilling rig guide hole is minimized.

[0007] The inner wall surface of the first cylinder is provided with an insertion hole, and the inner wall surface of the second cylinder is fixedly connected with an insertion rod, which is inserted into the insertion hole to connect the first cylinder and the second cylinder.

[0008] The first cylinder and the second cylinder are fixedly connected by inserting the insert rod into the insert hole, which is not only convenient for disassembly and installation, but also convenient for placing explosives in the cylinder, reducing the workload of operators and saving time and effort in operation.

[0009] The bottom surface of the containing cylinder is fixedly connected with a base, and the base includes a first base and a second base.

[0010] The provided base can increase the mass of the entire containing cylinder, so that it will not jump out of the drill hole after blasting to accidentally injure the operator, and the use is safe and reliable.

[0011] The outer wall surface of the base is fixedly connected with fixing rods, the number of the fixing rods is two, and the fixing rods are symmetrically arranged along the center line of the containing cylinder.
