The drilling hole diameter of the excavator is 42-110mm, suitable for ordinary hard rock layers, and can achieve good results for general blue rock and limestone. The drilling efficiency can reach 0.5-2 meters/minute, and the drilling arm track length is 3 or 6 meters, with a drilling depth of 20 meters (which can be completed by changing the rod). How to reduce usage costs and improve service life during use?
The hydraulic assembly of the drilling rig provides the torque of the high-speed hydraulic motor, while the air compressor assembly is responsible for the main drilling operation, providing the impact force of the impactor and completing the slag discharge. Due to the high requirements for air compressors, using high-capacity air compressors on small excavators may not be able to load them and require separate towing. Recommend modifying the excavator with a low tonnage of 8 tons.
1. Try to avoid the influence of hazardous elements as much as possible
1) Avoid impurities
For hydraulic rock drilling rigs that need to work in harsh environments and complex environments, it is necessary to first use high-quality, matched spare parts, lubricating grease, and lubricating oil to plug the source of harmful impurities; Next, we need to do a good job in on-site mechanical prevention to ensure that the relative organization can work normally and prevent various residues from entering the equipment.
2) Suitable for temperature
In the application process of excavation and modification drilling rigs, it is necessary to avoid overloading operation at low and high temperatures, ensure the normal operation of the preheating process, and ensure that the equipment meets the standard temperature before starting operation or running.
3) Anti corrosion
Effective measures should be taken based on the local weather conditions and environmental pollution at that time to reduce the impact of chemical corrosion on equipment. The top priority is to avoid the invasion of precipitation and chemical components in gases into equipment.
2. Moderate operating load
The size and characteristics of the operating load of the drilling rig have a critical impact on the consumption process of the equipment. Stable loads result in less damage, fewer failures, and a shorter service life compared to dynamic loads. Therefore, it is necessary to ensure that normal operating loads are not carried out under loads that exceed the capacity of the equipment. The second is to ensure the symmetrical addition and subtraction of equipment load as much as possible, so that the equipment is in a relatively light and gentle load change.
3. Reasonable use of lubricating oil
Due to the precision of coordinating various components of the hydraulic rock drilling rig, excellent lubrication can maintain normal working clearance and suitable operating temperature, thereby reducing the degree of component damage and equipment failure. Normal and effective lubrication is one of the useful measures to reduce equipment failures. Therefore, one is to use lubricating fluid correctly. Secondly, it is necessary to frequently inspect the quantity and quality of lubricating fluid.
4. Moderate maintenance and repair
The harm of some faults in the drilling rig to industrial equipment may be subtle, while some may be more serious. Severe mechanical failures are usually caused by smaller faults. Therefore, for mechanical failures, regardless of their size, they should be immediately cleared and moderate maintenance and repair work should be carried out.
5. Process and organizational coordination should be appropriate.
One is to pay attention to ensuring that the excavation and modification drilling rig avoids damage, deformation, rust, etc. during transportation and storage.
The second is to adhere to the principle of daily mechanical protection work, so that the equipment is in excellent process mode.
Thirdly, it is necessary to train the operators to properly use and operate various types of excavation and renovation drilling machines, in order to reduce and avoid equipment failures caused by human errors.
The fourth step is to carefully maintain the drilling rig, ensuring proper and effective regular and irregular maintenance, maintaining the cleanliness and tidiness of the equipment, regularly maintaining the process of the equipment, handling abnormalities properly, immediately locking and adjusting loose and unbalanced parts, and carrying out protective replacement of certain vulnerable parts.
