Description

A self-moving water jet drilling rig

technical field

The invention belongs to the field of drilling equipment, in particular to a self-moving water jet drilling machine.

Background technique

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 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 needed to move, and the labor intensity of workers is relatively high.

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. Therefore, it is very necessary to develop a self-propelled drilling rig that is suitable for the needs of the working face, has a large propulsion force, a strong back seat support, is intrinsically safe and explosion-proof, and improves the labor intensity of the workers.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide a self-propelled, self-propelled, large propulsive force, strong back seat support, intrinsically safe explosion-proof, low labor intensity, which is simple in principle, reliable in structure, light in operation, and suitable for high-efficiency working surfaces.

The rotation of the feed motor can drive the driving pulley to rotate, and the driving pulley drives the multi-ribbed belt to move, and the multi-ribbed belt can drive the fixed upper sliding saddle to move in translation, and then the drilling machine can realize the feeding movement; in the feeding cylinder Under the action, the slide rail can slide on the lower saddle, so that the water jet drilling device can move forward and feed as a whole.

The water jet drilling device is composed of a drill bit, a high-pressure drill pipe, a drilling rig, a high-pressure water tail, and a high-pressure pump. The water jet drilling device is set above the top beam of the lifting device. The drilling height is controlled by the lifting cylinder, and the drilling inclination (perpendicularity) is controlled by the tilting cylinder, so that the drilling height and inclination (perpendicularity) are equal. adjustable. The water jet drilling technology is adopted, the drill bit is small in size, small in recoil, small in vibration, easy to operate; no dust, no heat, strong fireproof, explosion-proof, anti-chemical reaction performance; dust suppression and cooling effects are obvious, which can improve the construction site condition, long service life.

Under the action of the rear support oil cylinder, the rear support beam can rotate downward when the equipment is drilling, press the ground tightly, provide a strong rear support force, and ensure the stability of the equipment when it is working; when the equipment is turning or walking At this time, it can be lifted up and off the ground without affecting the walking and steering of the equipment.

The joystick controls the whole device, and is easy and flexible to operate, and is arranged at the rear of the whole machine.

The hydraulic pump station and the water tank may not be installed when the equipment is used in the underground, but are all collected from the existing equipment on the working face; the equipment needs to work alone, and the existing equipment on the working face cannot provide corresponding oil cylinders. When the hydraulic source and water source are used, the hydraulic pump station and water tank need to be configured. The hydraulic pump station and water tank are arranged on the left and right sides of the walking frame, which can reduce the center of gravity of the entire equipment and improve the stability of the equipment when it is working.

The beneficial effects of adopting the above technical solution are: the working medium of the self-moving water jet drilling rig is water, the water resource is abundant and easy to obtain, and the cost is low. During the cleaning, crushing and cutting process, no arc, dust and toxic gas will be generated.
