Reverse circulation rotary drilling rig of two shifting mechanism of reverse circulation drilling rig swivel host structure includes an electrical control system, hydraulic system, the impact of winches, deputy hoist, main transmission, impact mechanism, operating system, tool winches, rigs, turntable, base, etc., which together constitute the supporting components of reverse circulation rotary drilling rig production line. Reverse circulation rotary drilling rig have two forms of travel shift mechanism A walk shifting mechanism is a horizontal, vertical hydraulic walking mechanism, which is a small pitch and underground continuous wall construction is particularly convenient, the other is mechanical shift means a small caterpillar drilling rig equipment, base mounted on the side walk round, walking round walking on the rails. Forward speed and rotation speed of the importance of the project to rig among recent years of development, domestic infrastructure and municipal engineering and other construction market booming, many drilling rig manufacturers to strengthen the development and research of all types of construction equipment, in particular For the production needs of drilling rig equipment. With the continuous improvement and improve products based engineering drilling equipment, construction equipment and more to the mechanical, electrical, fluid integration of direction developed constantly led the Chinese Engineering Construction Drilling Rig in the technical performance is constantly updated development. Full hydraulic drilling rig in the power head and feed mechanism is usually the most important drilling rig execution unit. Drilling rig in the production of hydraulic power rotary head drive drilling and production of small caterpillar drilling rig manufacturers, feed mechanism driving power of the rotary drill head while achieving drill feed, and then complete the project drilling rig. According to the actual production situation, the actuator should be able to achieve a high and low speed rotation and fast, slow feed crawler drilling rig working small price to meet the different conditions of small caterpillar drilling rig construction, thus achieving the most productive economy, so the analysis view, Engineering Drill feed speed and rotation speed control system related to the production of quality engineering rig.
