Excavator drilling rig is a tool used for directly mining stone materials. It drills on rock layers to complete the extraction of stone or other rock engineering.
As a meritorious service in rock mining, the excavator drilling rig cannot be ignored. In addition, the excavator can also be used as a breaker to break hard layers such as concrete. Rock drills can be divided into four categories based on their power sources: pneumatic rock drills, internal combustion rock drills, electric rock drills, and excavation drilling rigs.
Attention should be paid to the following matters during the use of the excavator drilling rig, and correct use can bring greater benefits.
(1) When using a drilling rig for rock drilling, the pusher should be placed in the drilling position so that the front end is pressed against the rock. Be careful to allocate and move the drilling rig forward so that the drill bit touches the rock; When drilling, quietly let the drilling rig push first, and when the drill rod is in place in the rock, allocate it to the fully open position.
(2) Before starting the excavation and modification drilling rig, it is necessary to check whether the inflation pressure of the accumulator is normal; Check if the flushing water pressure and lubrication air pressure are sufficient; Check if there is sufficient lubricating oil in the lubricator and if the oil supply is appropriate; Check the reverse tendency of the oil pump motor.
(3) If the drilling rig cannot smoothly open the hole, the rock drill should be assigned to retreat first, and then the rock drill should be moved forward to start the hole from the beginning.
(4) When replacing the drill bit of the drilling rig, the drill bit should be lightly pressed against the rock, and the motor of the drilling rig should be reversed to complete the sensitive unloading of the fiber head.
(5) The inspection of hydraulic components can only be prevented under extreme cleaning conditions. After removing the connecting tissue, it is necessary to quickly plug it with a cleaning and fitting plug. Before using the repaired hydraulic system of the rock drill from scratch, it is necessary to pump hydraulic oil into the oil circuit in a circulating manner to wash the components of the hydraulic system.
(6) Regularly check the oil level and fuel supply of the lubricator; Regularly add high-temperature resistant grease to the gears of the reverse organization; Regularly check the oil level in the lubrication tank and remove any dirt and impurities from the tank.
(7) Most of the current excavation and renovation drilling rigs are equipped with buffering devices, and some heavy-duty excavation and renovation drilling rigs also have recoil devices. The buffering device is primarily used to absorb the energy generated by the rebound of the drill rod, prevent the rebound of the drill rod from causing rigid impact between the relevant components and the body, and facilitate the service life of the moving drill rod and the body. The recoil device is designed to provide a reverse impact force to the drill rod in a stuck state, and to pull the drill rod out of the borehole in reverse.
(8) When not in use, use a tight fitting protective plug to plug all oil ports, completely wash the machinery, and release the gas in the accumulator. The rock drill should be stored in a rigid cleaning center.
