Self-moving type water jet drilling machine

Abstract

The invention belongs to drilling machine equipment and particularly relates to a self-moving type water jet drilling machine. The self-moving type water jet drilling machine is composed of a walking device, a lifting device, a feeding device, an inclination adjusting oil cylinder, a stabilizing oil cylinder, a water jet drilling device, a control rod, a rear supporting oil cylinder and a rear supporting seat. The drilling machine is capable of achieving crawler belt self-walking, stable in walking, high in climbing ability, capable of turning in situ and flexible; the water jet drilling technology is adopted, and a drill bit is small in size, small in recoil and vibration and convenient to operate; dust and heat emitting are avoided, and the fireproof, anti-explosion and chemical reaction resisting capability is high; meanwhile, the dust fall effect of water can be used for remarkably reducing dust on a working surface, and the field construction condition is improved; the service life of related matching machines can be prolonged with the cooling effect of water; the drilling depth, height and perpendicularity are all adjustable, and the drilling machine is especially suitable for drilling coal mine underground gas extracting and exhausting holes, advanced detection holes, fluid injection fire-fighting holes, coal bed water injection holes, outburst prevention pressure releasing holes and geological exploring holes and other engineering hole construction.

Description

technical field [0001] The invention belongs to the field of drilling equipment, in particular to a self-moving water jet drilling machine. Background technique [0002] Existing electric drilling rigs and mineral oil hydraulic drilling rigs need to be equipped with a separate power source, such as an explosion-proof power supply or a hydraulic pump station, which will inevitably increase the weight and volume of the system, affect the assembly, disassembly and movement of the drilling rig, and must consider the explosion-proof safety of the supporting electrical appliances And the potential safety hazard of mineral oil itself, especially when it is used underground in coal mines, the potential safety hazard is relatively large. Existing anti-outburst drilling rig structures generally have several forms such as hand-held, column-mounted, and rack-supported types: the hand-held structure is characterized by supporting the drilling rig by manpower or by simple brackets, and ma...

Problems solved by technology

[0002] Existing electric drilling rigs and mineral oil hydraulic drilling rigs need to be equipped with a separate power source, such as an explosion-proof power supply or a hydraulic pump station, which will inevitably increase the weight and volume of the system, affect the assembly, disassembly and movement of the drilling rig, and must consider the explosion-proof safety of the supporting electrical appliances And the potential safety hazards of mineral oil itself, especially when used in underground coal mines

Existing anti-outburst drilling rig structures generally have several forms such as hand-held, column-mounted, and rack-supported types: the hand-held structure is characterized by supporting the drilling rig by manpower or by simple brackets, and manpower propels the rig to drill. Larger, and because the drilling rig is manually propelled, it will inevitably lead to insufficient torque and propulsion, causing a series of problems such as insufficient hole depth, unstable operation of the drilling rig, and low drilling efficiency; Pillars are erected in the roadway of the working face to support the drilling rig, and the drilling rig is still driven by manpower, which has problems such as high labor intensity and insufficient cobalt machine capacity, and the erection and movement of the pillars are inconvenient, time-consuming, labor-intensive and low in efficiency; The characteristic of the supporting structure is that the drilling rig is fixed in the roadway of the working face through the frame fixed together with the drilling rig, and the feeding device built in the frame is used to push the drilling rig to drill. When moving, the frame and the drilling rig need to be disassembled and moved, which is inconvenient The disadvantage is that manpower is still required to move, and the labor intensity of workers is relatively high

[0003] In summary, it is not difficult to see that the existing downhole drilling rigs cannot well meet the needs of efficient construction at the working face
