Crawler Cleaning Method of Water Well Drilling Rig -- Yikuang Science and Technology
The water well drilling rig crawler is composed of crawler shoes and crawler pins. The track pins connect the track shoes to form a track link. There are holes at both ends of the track shoe to mesh with the driving wheel, and there are guiding teeth in the middle to regulate the track, and the water well drilling rig prevents the track from falling off when turning. The side in contact with the ground has reinforced anti-skid ribs (referred to as patterns) to Improve the firmness of the track shoe and the adhesion between the track and the ground. The water well drilling rig chassis also has supporting chain wheels, roller wheels, driving wheels and rail chain links. When cleaning and cleaning the crawler of the 2. water well drilling rig, the sludge on the lower walking body shall be cleaned at the same time. After the operation is completed, the operators shall clean and drive.

Which part does the drill chuck refer to and what role does it play?
Answer: The chuck is an independent and important component of the drilling machine. Its function is to clamp the drill pipe on the drilling machine, transmit torque and axial force to the drill pipe, and drive the drilling tool to realize rotation and feed. The chuck is composed of clamping components, intermediate transmission mechanism and clamping power device. According to the way of obtaining the force, it is mainly divided into mechanical chuck and hydraulic chuck. Mechanical chuck clamping and loosening by manual operation, the structure is relatively simple, but the operation is laborious and time-consuming, can only drill some shallow holes. The hydraulic chuck uses the hydraulic cylinder to provide the force directly or indirectly to make the clamping member perform the clamping action, which has the advantages of rapid action, easy centralized control and program control.

How to match the geological drill pipe with the drilling rig?
Answer: Φ34mm-Φ50mm small diameter geological drill pipes can be used together with pneumatic column drilling rigs (ZQJC160 to 1000) with torque below 1000N/m/full hydraulic tunnel drilling rigs for coal mines (ZDY400, 540, 650, 1200). Large diameter geological drill pipes above Φ63.5mm are generally used together with full hydraulic drilling rigs (ZDY1900, 3200, 4000,) and crawler full hydraulic tunnel drilling rigs (ZDY6000), in addition, the matching of drill pipe and drilling rig should also take into account the drilling diameter and depth of the drilling rig, and the drilling diameter is inversely proportional to the depth.

What is the material of 42CRMO and 42CRMOA and what is the difference?
Answer: There is a symbol after the grade of round steel, which means that the content of phosphorus and sulfur is low. There is no difference between 42CRMO and 42CRMOA in other aspects, and we know that the content of phosphorus and sulfur will seriously affect the performance and strength of steel. The one with A indicates high quality, less impurities and better performance.
