10 Operating Tips For Rotary Drilling Rig
1. Check the oil level of each running assembly before drilling.2. Check all connecting bolts and fastening studs, and tighten them in time in case of looseness.
3. Check whether there is oil leakage, water leakage and air leakage in all parts.
4. Add calcium base grease lubricant to each lubricating point on time.
5. Each shift shall drain the water in the oil tank of the drilling pan.
6. During drilling, the force value of the winch shall be determined according to the size of the drill bit and the geological conditions to keep the drill bit suspended. When the slag discharge is interrupted, the drill bit shall be lifted immediately and lowered slowly after the slag discharge. When stopping drilling, first lift the drill bit and then stop the wind.
7. Before the drill head assembly runs, be sure to turn on the oil pump motor to keep the system in good lubrication condition.
8. The holes shall be covered with wooden boards, and tools and iron parts shall not fall into the holes.
9. In the process of drilling, if the pointer of the ammeter swings sharply and the instantaneous current exceeds the allowable value and the power cannot be cut off automatically, the drilling should be stopped and then started. Instead, the drilling should be started with light weight on bit and slow speed, and the drilling should be resumed after it is normal.
10. Low speed should be used for drilling in rock and sand.

Track shoes are common walking parts of construction machinery, and are also one of the main parts that are easy to wear. They are widely used in crawler crane, piling machine, bulldozer, and excavator.
1. One Machine Can Be Used for Multiple Purposes to Realize Multiple Drilling Methods. Firstly, the design of large pile hole and foundation construction drilling rig makes full use of hydraulic transmission technology, adopts modular combination design method, and realizes multi-purpose of one machine without changing the main machine, so as to meet the adaptability of large construction machinery to different construction methods.
1. When unwinding and installing the wire rope In order to prevent damage to the wire rope lay structure, the correct method should be adopted; In addition, when winding the wire rope to the drum, do not make the surface of the wire rope with sand. So as not to aggravate the wear, affect the life of the wire rope.
1. During construction on the soft soil ground, it is easy to attach soil to the track and track link. Therefore, the track shall be slightly loosened to prevent the attached soil from exerting abnormal stress on the track link. 2. When constructing on the ground with pebbles, the track should also be slightly loosened, so that the bending of the track shoe can be avoided when walking on the pebbles. 3. When constructing on firm and flat ground, it is better to adjust the track slightly.
XCMG XR550D rotary drilling rig consists of telescopic crawler undercarriage, large diameter swing bearing, full single row winch wire rope, self lifting foldable drilling mast, telescopic Kelly bar and other components.
Firstly, the auger drilling rig is simple in structure and fast in installation. The operator only needs to connect the drill pipe with the power head. Drill pipes are usually installed and used according to different conditions. The rotary drilling rig has more components than the auger drilling rig. In terms of Kelly bar, interlocking Kelly bar, friction Kelly bar and combined Kelly bar are mostly used, which can be directly put into place during operation.
Rotary drilling rig is a kind of construction machinery for soil borrowing and bored pile, which is widely used. What do you know about rotary drilling rigs that have been used for so long? What are its main components? You know what?
