Maintenance of rotary drilling machine Today, I led everyone to master the maintenance of rotary worktable of rotary drilling machine. I think everyone knows the person responsible for the rights of the rotary drilling rig and should also know its efficacy. Rotary table output great torque and working pressure, but it also bear the load, vibration, impact, so the rotary table is a rotary excavator. The core component is also the most problematic component. So, let's revisit today's topic of discussion.

1. maintenance countermeasures:
(1) Check and replace the rotary table spline shaft oil,
(2) Remove and replace the lubricating grease of rotary table of rotary drilling rig;
First of all, let's talk about the process of regularly checking and replacing the oil of the spline shaft of the rotary table and how to replace the grease of the rotary table of the rotary drilling rig. Check and replace the rotary table spline shaft oil
1. Check the height-width ratio of the lubricating fluid in the transmission according to the glass of the transmission cover from beginning to end, and ensure that the amount of oil is not less than the 2/3 of the vertical height-width ratio of the window. (The rolling bearings in the reduction gearbox are moistened by oil. If the amount of oil is too low, the rolling shaft is not well moistened, which will reduce the service life of the machine.)

2. When changing the oil, turn the oil adding screw of the transmission gear of the rotary table to the bottom first, which is convenient for actual operation and oil drainage.
3. Remove the pouring oil plug and oil plug, let the oil of the rotary table drain into suitable vessels, and slowly rotate the transmission gear of the rotary table during the whole process of pouring, so as to facilitate oil drainage and air pollution. To ensure safety, when the transmission gear rotates, the relevant staff should be put out on the spot.
4. Check whether the power plug and sealing are intact. If there is significant damage or destruction, replace it with a new one.
5. After draining, install the oil plug.
6. Twist off the hydraulic rubber hose joint of the energy storage device at the top of the driving force head, pay attention to the cleanliness of the joint, and introduce grease (220 super heavy industrial gear oil) to the reduction gearbox according to the joint hole. In addition, check the oil amount according to the observation mirror and add it to the 2/3 of the aspect ratio of laminated glass, but it should not be full. If it is full, it will cause the hydraulic seal of the rotary table to leak, so that the gear oil or water into the reduction box, which is likely to environmental pollution reduction box.
7, after the process, tighten the hose joint removed in process 5 and install the oil plug. Relevant tightening torque, customer program appendix.
8. Start the diesel engine and let the rotary table drive gear rotate twice.
9. Terminate the diesel engine and check whether the oil quantity is higher than the 2/3 of the aspect ratio of the window.

Removal and Replacement of Lubricating Fluid for Rotary Table of Rotary Drilling Rig
1. Remove the inspection cover located directly under the controller of the rotary table.
2. Remove the drainage pipe from the support frame on the upper structure, and one end of the plastic hose faces the vessel.
3. Loosen the drain valve with a cross shaft with a sleeve specification. Discharge the oil to a suitable vessel.
4. Tighten the drain valve. Hanger the water drainage line on the support frame. Ensure that the plastic hose ends up.
5. Remove the oil dipstick from the rotary worktable of the rotary drilling rig.
6, according to the dipstick tube filling measurement verification oil.
7. Maintain the amount of oil between the top of the oil dipstick and the oil dipstick mark.
Today, we will correctly guide you to master the rotary drilling rig rotary table maintenance measures. Let us master the maintenance and maintenance of the rotary table drive equipment again tomorrow.
