Specification for use of rotary drilling rig

1. After starting the vehicle, it should run slowly for 3-5min and rotate the rotary table under full load to facilitate the normal operation of the hydraulic transmission system.

2. During the operation of the drilling rig, the operators should regularly observe and check whether there are any problems with various instrument panel signs. If there are any abnormal phenomena, parking inspection should be carried out in time.

3. During the operation, it is necessary to pay attention to the actual operation of the operating handle in time to prevent the system from causing the impact of working pressure.

4. In use, check the tightening pressure of the three-way joint and the gasoline pump to tighten the bolts to ensure that there is no oil leakage or steam leakage.

The drilling rig needs to be guided by full-time personnel when walking, especially in dangerous areas such as high-voltage wires and puddles.

6. It is forbidden to sit within the rotation range of the drilling rig.

7. After the whole conversion process of the drilling rig, the truck under the flatbed must immediately open the crawler type to move around.

8. When checking the gear oil, be sure to wait for the gear oil to be cold.

9, arc welding drill pipe components, be sure to unplug the power switch.

10. Check the rotary joint on time.

The above aspects are also the operators must take into account during the operation of the rotary drilling rig. Before construction, during construction and after construction, there are special attention areas. The importance of rotary drilling rig in pile engineering projects is obvious. Although its effect and quality are very reliable, it is always a large-scale mechanical construction. Attention should be paid to it and cannot be settled.

The value of the rotary drilling rig, but to maintain a good point.

Rotary drilling rig as a foundation engineering pile operation construction machinery and equipment, in addition to expensive, its work efficiency is also very high, so at this stage is widely used in pile foundation engineering. It is also very important to ensure the normal operation of the rotary drilling rig without delaying the construction period. For experienced masters, this kind of maintenance expertise is already quite familiar. Here, I will briefly introduce several aspects of maintenance precautions in detail.

Whether the 1. rotary support, drill pipe rotary support, shafts, sleeves, power box sports field, drill pipe sports field and rope lifter lack salt-free butter and their damage;

2. the whole car screws to check whether they are loose or fall off on time. Key parts: fixed car engine bolts, slewing bearing bolts, shaking head bolts, fixed drill pipe bolts, and walking reducer bolts;

3. check whether the galvanized steel wire rope is rusted or cracked. If the above situation occurs, it should be replaced immediately to avoid unnecessary trouble;

4. check the power circuit solenoid valve is not aging, early preparation of accessories;

5. check the damage of oil pipeline and sealing ring at any time and anywhere, and prepare accessories in advance to deal with urgent shortage;

6. check whether the rotation of the rolling bearing of the drill pipe rope lifter is flexible. If it is damaged, replace it immediately.

Some maintenance that needs to be done in the actual construction process and other situations need to be adjusted by the operators and masters according to their work experience. It's not easy to maintain such a large piece of equipment.
