Inspection Items before The Rotary Drilling Rig Starts Operation

A comprehensive inspection of the rotary drilling rig before its operation is an important prerequisite for ensuring construction safety and efficiency. The slightest oversight may cause malfunctions during the construction process and even lead to safety accidents. None of the following key inspection items can be ignored.

1. Mechanical appearance inspection: Carefully examine the body of the rotary drilling rig for any cracks or deformations, and check if the connecting bolts of each component are loose. If paint peeling or severe scratches are found, it is necessary to further inspect whether the internal structure is damaged.

2. Hydraulic system inspection: Check the oil level, color and viscosity of the hydraulic oil to ensure good oil quality and sufficient oil quantity. At the same time, check whether there is any leakage in the hydraulic pipeline and whether the joints are firm to prevent insufficient pressure or leakage problems during operation.

3. Power system inspection: Start the engine and listen to whether the running sound is smooth and if there are any abnormal noises or vibrations. Check the reserves of engine oil and fuel to ensure the engine can work continuously and stably, and avoid sudden engine stalling during construction.

4. Drill tools and accessories: Check the wear of the drill bit to ensure that the cutting teeth are sharp and the drill pipe is free from bending and cracking. Check the auxiliary devices such as steel wire ropes and pulleys to ensure that they have no broken wires or wear and operate flexibly.

5. Electrical system inspection: Test whether the displays of various instruments are normal and whether the lighting and alarm devices can work properly. Check for any damage or aging of the circuits to prevent potential safety hazards caused by electrical faults.

6. Site and surrounding environment: Confirm that the construction site is flat, solid, and has a load-bearing capacity that meets the requirements for drilling rig operations. At the same time, observe whether there are any obstacles such as high-voltage lines and underground pipelines around, and plan the construction safety area in advance.

In conclusion, the inspection of a rotary drilling rig before its operation should cover multiple aspects such as the machinery itself, power system, drilling tools, and electrical systems, while also paying attention to the site environment. Only by conducting every inspection thoroughly and leaving no detail unchecked can the rotary drilling rig operate safely and efficiently during construction, ensuring the smooth progress of the project.
