Benefits of Air Leg Rock Drill
Security
Safe to use, fully pneumaticand can be used in closedenvironments, no sparks.
Excellent Adaptability
Performs reliably under various harsh conditions (wet, dusty, high-altitude environments) without being affected by water or dust ingress.
High -Quality Part
On the premise of ensuring power, the air leg rock drill machine's gas consumption is only 5 m³/min, which reduces energy consumption by 10%-15% compared with traditional air leg drills.
Simple & Reliable Structure
IWith fewer components and a durable design, it ensures minimal failure rates, easy maintenance, and low long-term operational costs.
Application of Air Leg Rock Drill
Mining Field
In mining, air leg rock drill machine is mainly used for tunnel excavation and blast hole drilling before ore mining.
Railway Construction
In railway construction, air leg rock drill machine is responsible for drilling blast holes during tunnel excavation to facilitate tunnel excavation.
Transportation Construction
In the field of transportation construction, such as the construction of infrastructure such as roads and bridges, air leg rock drill machine is also often used for rock drilling operations in rocky areas.
Water Conservancy Construction
In the field of water conservancy construction, air leg rock drill machine is mainly used for rock excavation operations in water conservancy projects such as hydropower stations and dams.
Troubleshooting And Handling Of Air Leg Rock Drill
(1) Causes of failure: First, the working air pressure is low; second, the air leg is not telescopic, the thrust is insufficient, and the fuselage jumps backward; third, the lubricating oil is insufficient; fourth, the flushing water flows into the lubrication part; Affecting exhaust; Sixth, the wear of main parts exceeds the limit; Seventh, the phenomenon of “hammer washing” occurs.
(2) Elimination measures: First, adjust the pipeline to eliminate air leakage, increase the diameter of the air supply pipe, and reduce the gas consumption equipment; and whether the reversing valve is lost, damaged or stuck; the third is to add oil to the lubricator, replace the polluted lubricating oil, clean or blow through the small holes of the oil circuit; the fourth is to replace the broken water needle and replace the brazing rod that blocked the center hole The fifth is to knock off the condensed ice cubes; the sixth is to replace the worn parts in time; the seventh is to reduce the water pressure and overhaul the water injection system.
(1) Causes of failure: First, the small end of the piston is seriously piled up or the center hole of the shank is not correct; the second is that the clearance between the shank and the hexagonal sleeve is too large; the third is that the water needle is too long; the fourth is that the reaming depth of the shank is too shallow .
(2) Elimination measures: first, replace it in time; second, replace it when the opposite side of the hexagonal sleeve is worn to 25mm; third, trim the length of the water needle; fourth, deepen it according to the regulations.
(1) Causes of failure: First, the water pressure is too high; second, the gas circuit or water circuit is blocked; third, the parts in the water injection valve are corroded; fourth, the spring of the water injection valve fails due to fatigue; fifth, the sealing ring is damaged.
(2) Elimination measures: One is to appropriately reduce the water pressure; the other is to dredge the air passage or waterway in time; the third is to clear the rust or replace it; the fourth is to replace the spring; the fifth is to replace the sealing ring.
(1) Causes of failure: First, the water needle was removed; second, the lubricating oil was too thick and too much; third, water was poured into the machine.
(2) Elimination measures: First, refill the water needle; second, adjust properly; third, find the cause and remove it in time.
(1) Causes of failure: First, the air pressure in the pipeline is too high; second, the high power is suddenly turned on.
(2) Elimination measures: one is to take pressure reduction measures; the other is to start the rock drill slowly.
