The role and application of the Hydraulic auger

Hydraulic auger, a complex set of machines, is composed of machines, units and mechanisms. Hydraulic auger is a mechanical device that drives drilling tools into the ground to obtain physical geological information in the exploration or mineral resources (including solid ore, liquid ore, gas ore, etc.) development. Also known as drilling machine, the main function is to drive the drilling tool to break the rock at the bottom of the hole and lower or raise the drilling tool in the hole. It can be used to drill cores, mineral cores, rock chips, gaseous samples, liquid samples, etc., in order to explore the underground geology and mineral resources, ល។. Here is the introduction of our Hydraulic auger

Working Principle
The spreader ring is connected with the spreader ring seat by pin, the spreader ring seat is welded to the hook bar, the barrel is connected with the hook body by left-hand thread, and the threads are prevented from loosening by stop blocks. The hook body and barrel can move up and down along the hook bar. The function of inner and outer load spring is to make the vertical root pop upward after loosening the buckle when starting drilling.
The barrel body is equipped with oil. The seat ring of thrust bearing divides the oil chamber into two parts, and there are oil holes on the seat ring. Due to the damping effect of the oil flow, it absorbs the shock vibration of the hook body during its down-drilling operation and can prevent damage to the thread of the drill pipe joint.
The upper end of the barrel is composed of 6 small springs and positioning discs to form a positioning device. With the friction between the positioning and the annular contact surface of the spreader ring seat, it can prevent the spreader ring from being turned when lifting the empty spreader card.
Applications

Maintenance
1. Items for regular inspection of the Hydraulic auger
(1) Check the main structural condition of the Hydraulic auger, the bolts of the structural connectors, the pins of the structural connectors, the welds of each structural component, the structure of the basket and the safety protection condition, especially before entering the field for use, a qualified unit should be asked to test its safety performance and it should be used only after passing.
(2) Regularly inspect the condition of various power heads, working cylinders, drill bits and drill rods.
(3) regularly on the winch reel anti-wire rope shedding device and both sides of the edge height, reel wall condition, wire rope tail on the reel circumference for inspection, especially the condition of the brake mouth should be a key project for inspection at any time.
(4) the electrical system inspection, the main check items are: special electric box setting and short-circuit protection and leakage protection device, emergency power off switch, electric box damping device, the work device on the cable fixation, lighting line, grounding line is strictly prohibited for current-carrying zero line, etc..
2、Hydraulic auger should always check the items
(1) the steel wire rope rope end solidification situation to check.
The content of the wire rope inspection is: the number of wire rope safety circle, wire rope selection, installation, lubrication, wire rope defects check, such as wire rope diameter and wear, the number of wire rope broken wire, etc..
(2) Check the pulley system of the rig at any time, the main items are: the condition of the pulley body and the anti-jumping device of the transition pulley.
(3) Check the walking system of the Hydraulic auger at any time, the main items are: the condition of the pile rig walking pipe, cardboard and hook pipe system, sleeper laying, ល។.
(3) keep a good record of the maintenance of the rig, and keep a detailed record of the replacement parts to ensure that the parts are used within the validity period, or keep track of the time of the next replacement.
4、If the rig is faulty, it should be stopped immediately and should not be used until the fault is removed.
Precautions
Precautions for rig operation.
1. Do not start the Hydraulic auger until the power machine is running normally. The clutch should be connected smoothly and should not be impacted, and must be light, even and smooth.
2、When you turn on the gearbox or splitter handle to change the speed, you must first disengage the clutch and forbid to drive the gear.
3, each gear shift gear shift should be completely hung full, so as not to automatically slide gear damage.
4、Check the running parts during operation, such as bearings, gear box, ល។. The temperature should not exceed 60℃, such as overheating should be stopped to check.
5、If the clutch is found to be hot or slipping, it should be stopped for inspection and the clearance of the clutch friction plate should be adjusted. The gap should be adjusted appropriately. If it is too tight, the clutch will not be joined; if it is too loose, the clutch will work in a semi-clutched state, which will cause the transmission torque to be reduced and the friction plate to wear rapidly.
6、Before starting the Hydraulic auger, lift the drilling tool off the bottom of the hole, close the clutch, and then give pressure to drill after the rig is running normally.
7、When using the hoist, it is forbidden to press down the left and right hand grips at the same time, or to tighten the hand grips combined with the foot brake at the same time; the winch should not be overloaded to lift the weight.
8. Before starting a new Hydraulic auger or a rig that has been stopped for a long time, the rig should run at least 20 minutes at 2 speeds to allow the gears and bearings to be splashed with lubricant before drilling normally.
9. Lock the rig locking device before driving to prevent the rig from backing up due to vibration.
10、The tachometer should not be reversed. If the rotator needs to be reversed, the flexible shaft of the tachometer should be removed to avoid damaging the tachometer.
11. Do not move the drill rig during the drilling and lifting process.
12、If abnormal noise occurs during the operation of the Hydraulic auger, stop the rig to find out the cause and eliminate it.
13、In the case of automatic brake, the operator must not leave, and if necessary, the cam should be stuck by the pawl.
14、No oil should be splashed on the brake belt to avoid slippage.
15、All hydraulic control handles cannot be used at the same time; after the gear oil pump is started, pay attention to the reaction of the oil pressure gauge and the pressure indicator gauge at the bottom of the hole. During the drilling process, when the pressure at the bottom of the hole needs to be increased or decreased, it should be adjusted gradually and should not be increased or decreased suddenly; when using the hydraulic system to quickly lift the vertical shaft (fast reverse rod), it should only be done under the original load to prevent damage to the machine parts.
16、Manipulate the steel ball positioning valve, not too hard, should be skilled in each positioning position of the correct positioning point. When operating the spring-loaded automatic reset valve, it should be pulled to the bottom, otherwise it is easy to cause pressure shock damage to the pressure gauge.
17, in order to rationalize the use of the hydraulic system, to ensure safe operation, each state of the actuator, the working pressure value should be within the required range.
18, winch “water-cooled” after the end of use, the stored water should be drained and remove the rubber water seal coated with lubricant, so as to avoid rusting parts or freezing the reel.
19、Before moving the rig backward, unlock the rig locking device.
20、When the rig is not used for a long time, the exposed parts should be coated with lubricating grease to prevent rusting.
Troubleshooting
Common faults of the Hydraulic auger and methods of troubleshooting.
1、Insufficient pressure in the hydraulic system of the Hydraulic auger, regulator fatigue to adjust the limit nut or replace the spring; if the regulator seat cone is damaged or jammed, remove the regulator sleeve Jane to overhaul.
2, Hydraulic auger coupling heat, excessive wear of the elastic ring; the reason is the poor coaxiality of the Hydraulic auger power machine and clutch assembly, the need to improve the coaxiality of the assembly.
3, the Hydraulic auger oil pump does not start on the oil or the amount of oil is not enough, first row check whether the amount of oil in the tank is insufficient or no oil, refueling to the oil level line failure such as still not ruled out, to check whether the filter is blocked, in addition, also look at the tank vent hole is blocked, or the suction pipe joint loose air intake and other reasons.
4, rig winch brake slippage, the main reason is to hold the brake with oil on the inner surface, you need to remove the inner surface of the brake; if the rig hold brake without oil, check the brake belt and brake wheel clearance, such as too loose to properly tighten;.
5, rig clutch slippage, the main reason is excessive wear or rupture of the friction plate or compression spring aging or fracture, the rig friction plate should be overhauled.
6, rig oil pump heat and wear, repair and replace the oil pump, oil viscosity is too high or too low, to strictly follow the instructions of the oil; at the same time, check the transmission device of the rig oil pump, to improve the accuracy of the assembly.
7, the hydraulic system oil temperature is too high, too little oil in the oil tank or oil pump damage, ទៅ
