Efficient switching clubs systemically important project for the engineering drill rig, the drilling rig is a slope supporting exploration coring rock construction equipment. In previous times the economically underdeveloped, less drilling rig use, so technological development drilling rig is also lagging behind, but with the strong foundation engineering construction equipment, more and more drilling rig is used to extensive engineering drilling rig use, but also to more and more people began to pay attention to drilling rig efficiency, power, and security issues. Engineering drilling rig at the time of production, due to the use of drill pipe length restrictions, the need to constantly connect drill hole depth rated to complete drilling 600 drilling rig, upon completion of drilling operations when 600 drilling rig equipment, and the need to constantly drill demolition work, so continue drilling operations, continue to carry out demolition construction will reduce production efficiency, and therefore need to adopt new production techniques, to change these backward production efficiency to address different aspects of the project Drill production problems, it is also true, to design a high efficiency, good security system for automatic switching clubs drilling rig, it is particularly important, but also very necessary. At present, various drilling rig in the construction process, mostly done by manual drill pipe handling, not only inefficient, but also for the operator's safety compromised. For this situation, a new drill rod changer library design, carried out the design of its mechanical structure and hydraulic systems, and details of their step process. It can carry six drill, the hydraulic system control robotic handling drill and automatic switching clubs, high-efficiency 600 drilling rig price, good security. Keywords: drilling rig; automatic switching clubs; proposed drill rig library project is an important device 1. Problem Slope Support, exploration coring geotechnical construction. With the extensive application engineering drilling rig, there is growing interest in the work efficiency of the rig, power, and security issues. Drilling rig during drilling, drill pipe length is limited, the need to constantly tipping drill hole depth rated to complete drilling; after the completion of drilling operations, and the need to constantly drill disassembly. Currently most of the drilling rig are dropped first by elevator or lift much money 600 drilling rig drill, drill work immediately after 卡瓦卡 lower part, by a winch system and workers to accomplish the task handling drill. For some large drilling rig, as long drill pipe and heavy, not moving, several workers need to work together to complete the change lever, which requires a lot of labor-intensive, the need for some of the heavier drill pipe and the other with lifting machinery . These are largely extended the drilling operation time, reduce the efficiency of construction. At the same time due to limitations drilling rig working environment, particularly in the high drilling and upwardly inclined drilling process, manual handling particularly difficult drill workers during operation due to an oversight could lead to major construction casualties. Therefore, the design of a high efficiency, good safety wrap rod system is particularly important. 600 drilling rig picture _ the Prius _ Heshan 600 drilling rig provided by Luoyang Prius Drilling Equipment Co., Ltd.
