Several tips for getting started with rotary drilling rig quickly
Operation method of starting and drilling of rotary drilling rigFirst, the strongest power is required at start-up, and low speed control is required during operation, so it is easy to overcome various resistances from static to dynamic. When some equipment is in operation, it still needs to accelerate and decelerate quickly， due to tonnage Heavier, when stopping, be sure to slow down first to reduce the impact of acceleration.Second, the drilling technique is directly related to the geology of the construction: when drilling in the geology of the soil layer, the resistance encountered is relatively small, the highest performance of the rotary drilling rig can be used, and the high torque can quickly drill and improve Construction efficiency;When encountering sandstone layers, due to higher resistance While drilling with high torque, the rotary drilling rig needs to pay attention to increase the pressurized oil cylinder to maintain load balance and reduce resistance;in case of pebble layer, special attention shall be paid not to hard drilling. This kind of geological reaction is relatively strong. When drilling, slow pressure and low torque shall be applied to minimize the vibration;When encountering particularly hard and high-density geological conditions, after selecting the appropriate bit, steadily operate the drill to output and pressurize with large torque to overcome the resistance brought by drilling into the geological conditions.
Introduction of small rotary drilling rig
In recent years, due to its excellent performance and affordable price, Shandong's small rotary drilling rig has won the favor of the engineering construction team, ranging from the construction of engineering buildings to the construction of towns and villages, and the advantages of rotary drilling rig have really changed the concept of pile foundation construction.The highly automatic control system and advanced construction design scheme make the work that used to take more than two months to complete, now it only takes six days to complete,It can not only save the labor cost, but also greatly shorten the construction time of the project. With such high efficiency, it is really a "tool for drilling money". Now all engineering teams are inseparable from the construction of rotary drilling rig.
Precautions for the novice to open the rotary drilling rig for the first time
Instructions for crawler rotary drilling rigs, workers should pay attention to the following points during the pile driving process to avoid accidents!1.The red light should be installed on the top of the column of the crawler rotary drilling rig (hereinafter referred to as rotary drilling rig), which must be lit at night to show the height warning sign and be installed by the user according to actual conditions.2. The top of the column of the crawler rotary drilling rig should be connected to the lightning rod according to the regulations, and the work should be stopped during the lightning strike.3. The track should be on the ground when the rotary drilling rig is working.4. The working wind force is greater than 6 grades, the pile driver should be stopped, the oil cylinder should be used as auxiliary support, and the cable wind rope should be added for fixing if necessary.5. When crawler piling operation, the drill rod reinforcement cage should be avoided to collide with the column.6. The drill pipe is drilled into the ground or piled into the ground. It is strictly forbidden to move the pile frame.7. When the track rotary drilling rig is drilling, the ammeter current must not exceed 100A. When the current exceeds 100A, the lowering of the drill rod should be stopped, but the power head always drills. When the current drops below 100A and stabilizes, the drill rod can continue to be slowly lowered. .8. When pulling the sinking pile for pressure, the front of the pile frame should not be lifted.9. Crawler pile frame walking and moving pile position. The pile frame uses crawler walking. The slewing mechanism rotates to accurately align the pile position. When the position of the pile frame cannot meet the pile position requirements, it can walk or rotate back and forth.
The requirement of refilling hydraulic oil for rotary drilling rig
In the construction process, we must pay attention to observe the use of oil in the hydraulic oil tank, if it is found that the hydraulic oil is insufficient, it must be replenished in time, otherwise it will cause some failures. Are there any requirements for refilling hydraulic oil with a rotary excavator? The answer is yes, not all oil can be added. We must do it according to the requirements stipulated by the manufacturer of the rotary excavator, which can reduce the occurrence of failures and will not affect the after-sales service of the manufacturer to us.There are many types of hydraulic oil. When the hydraulic oil of the rotary excavator is found to be insufficient, the hydraulic oil should be filled according to the instructions of the rotary excavator. The type and brand of the hydraulic oil must be strictly selected, and the waste oil cannot be used. Different brands and different models It is strictly forbidden to mix the oil. There are also requirements for the accuracy of hydraulic oil, which must comply with the cleanliness specified by the manufacturer. If you choose poor quality hydraulic oil, it will cause damage to the hydraulic components of the rotary excavator, so we must not try to buy poor quality oil cheaply. We must purchase hydraulic oil according to the manufacturer's requirements, so as to ensure the integrity of the equipment, make our machines work better, reduce the occurrence of failures, and seek more benefits for us.
