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, 100 drilling rig where the selling, 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, Boli 100 drilling rig, and the need to constantly disassembly drill pipe. Currently most of the drilling rig are dropped first by elevator or lift the drill pipe, after the lower part of the drill 卡瓦卡 tight work, the 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. Drilling rig is applied in the construction of a more extensive mechanical, 100 drilling rig much money, it occupies an important role, let's learn more about some of the applications engineering drilling rig. Engineering drilling rig is mainly used in infrastructure construction, accounting for up to 60%, which was less in the mining industry and real estate applications, 100 drilling rig manufacturers, accounting for only about 10% are. Thus, the drilling machine will be the most large-scale infrastructure construction from the country's benefit, without the General Assembly affected the mining industry and the real estate investment growth fell sharply, and therefore works with domestic demand growth will remain stable rig . In addition, the drilling machinery industry has a high proportion of exports, but the industry itself smaller capacity, demand is more stable and few competitors worldwide, and the advantages of our business and very prominent, so we think can keep drilling machinery export sales a high growth rate. Hydrological and engineering drilling rig in hydrogeology, based mainly in exploration, combined exploration and mining principle, except to obtain information needed to evaluate the hydrogeological conditions, but also to meet the maximum amount of water possible to obtain the corresponding increase in hole diameter, construction General requirements for water supply well. Hydrological engineering drilling rig drilling rig to adapt to this need, for the hydrogeological drilling rig. Hydrological engineering drilling rig should have the ability twofold: not only drilling, taking core samples or rock; but drilling large diameter drilling and well completion operations conducted. These are the details of the project with some applications of the rig, I believe many people are able to gain from. 100 drilling rig where to sell the Prius, Boli 100 drilling rig provided by Luoyang Prius Drilling Equipment Co., Ltd.
