The daily maintenance of the drilling machine is to regularly start the column guide device, rotary mechanism, rotary bearing, oblique support mechanism, oblique support screw, etc. of the drilling machine. Select a spindle by understanding its power and speed characteristics. Next, we will introduce the relevant content in detail.
1、 Daily maintenance of drilling machine
1. The column guide device, rotary mechanism, rotary bearing, diagonal support mechanism, diagonal support screw, sprocket, guide wheel, and drive wheel bracket of the drilling machine should be started regularly. Regularly check and replenish lubricating grease.
(1) Regularly add lubricating grease to the copper sleeves at both ends of the main drum.
(2) The steering wheel should be lubricated at least once a week, and the track should rotate above the ground. Note: When the guide wheel rotates, it is necessary to add the guide wheel grease. If the grease does not overflow, it may be due to excessive filling pressure or inability to add. Therefore, the track should be removed and the guide wheel dredged.
(3) Check the hydraulic system every day to find out the shortage of hydraulic oil.
(4) Check whether the inclined support ball joint seat needs to be lubricated every day and replenish the oil in a timely manner.
2. The track chain should be cleaned daily to ensure normal operation of the track.
3. When the tilt support rotates, attention should be paid to whether there is a swing phenomenon. If there is a swing, it is necessary to replace the copper guide sleeve or copper nut in the inclined bracket in a timely manner.
4. Wire and tubing joints, cable joints, etc. are prone to friction and expansion, and protective tubes should be used to protect them.
5. The inspection, maintenance, and use of the drill wire rope should be carried out in accordance with relevant standards.
6. When working, pay attention to whether the ball socket under the diagonal support rod has string movement. If there is string movement, immediately stop working, remove the end cap under the protruding beam, make the diagonal support bear pressure, and tighten and lock the nut at the lower end. If necessary, use electric welding to weld the nut. When the temperature drops below zero in winter, it is necessary to check whether there is no water in the extended light beam, and timely drain the water to prevent freezing from loosening the nut.
7. The pumps, control valves, and oil tanks of the hydraulic system should be kept clean. Every time you change the oil in the oil tank, it is necessary to carefully clean the oil tank to prevent dust from entering the tank and causing failures.
8. Check the looseness of the drilling machine's power head, vibration hammer flange bolts, and operating mechanism bolts and nuts every day.
9. The wear of the sliding parts of the power head, the nylon sleeve of the pulley, and the copper sleeve of the main winch should be replaced in a timely manner.
2、 Method of Selecting Spindle for Drilling Machines
1) Understand the power and speed characteristics of the spindle.
Machine tool manufacturers publish spindle characteristics in their operating manuals. Here, you will find the low and high rpm for each scale, as well as the desired power for the entire rpm scale.
If you have never studied this important data, you may not have optimized your cycle timing. To make matters worse, you may apply excessive pressure to the spindle motor of the machine, or even cause the motor to stop rotating. Carefully reading the manual and understanding the spindle characteristics can help you optimize the productivity of your machine.
2) Know how long it takes to change the spindle size.
There are at least two types of spindle scale conversion systems: systems with spindle drive motors with multiple windings and systems with mechanical transmission devices.
The former changes on an electronic scale by modifying the motor windings they use. These changes are almost instantaneous.
Systems with mechanical gearboxes typically drive directly in their high gears and engage the gearbox in lower gears. Changing the scale may take a few seconds, especially if it is necessary to abort the spindle during the process.
