Anchor drilling rig is to adapt to the construction of some foundation projects, with the further development and improvement of technology and engineering requirements, anchor drilling rig is also in constant improvement and sublimation. No matter how the anchor drilling machine develops, it is based on the development of bolt support technology and rock drilling technology. Therefore, as long as we find ways to improve the level of bolt support and rock drilling technology, skid-type light hydraulic anchor and drilling machine are mainly used in hydropower, mine, dam body and road subgrade anchoring projects. Rock anchors are mainly used in mine anchoring projects, which require high hole forming accuracy and are generally constructed on scaffolding about 10 meters high, therefore, it is necessary to ensure that the drilling rig is flexible and convenient in shifting the scaffold, and also to take into account the stability of the drilling rig during perforation, and to be easily connected firmly with the scaffold. Generally, skid type I drilling rig should be adopted with a weight of about 1.6 tons, a rotary torque of about 3.OkNm and a propulsion lifting force of about 5 tons. Rock drilling using air down-the-hole hammer is the most effective method.

 

The development of anchor drilling rig is based on rock drilling technology and anchor support technology. High drilling speed, good adaptability, high reliability and high quality service from manufacturers are the goals of anchor drilling rig product competition. The research on the performance parameters of the anchoring rig, the rationalization of product structure design and material selection, and the establishment of product quality assurance system are the basis for the further development of the anchoring rig products. Anchoring rig is the construction machinery of anchor support, which affects the construction quality of anchor support -- the orientation, depth, aperture and installation quality of anchor hole. The technical characteristics of the product itself also involve the safety of the operator.

 

Anchor drilling rig is the key equipment of bolt support, which affects the quality of bolt support-the location of the bolt hole, depth, the accuracy of the aperture and the quality of bolt installation, but also involves the operator's personal safety, labor intensity and operating conditions. Although the domestic industrial level is low compared with foreign advanced industrial technology. The development of domestic anchor drilling rig has experienced a long history of more than 30 years, but the achievements are amazing. It has successively developed mechanical outrigger electric anchor drilling rig, drill truck type anchor drilling rig, outrigger and guide rail type hydraulic anchor drilling rig, outrigger pneumatic anchor drilling rig, non-mechanical transmission outrigger electric anchor drilling rig, airborne anchor drilling rig and two-stage air leg rock drill. In recent years, with the improvement of domestic science and technology level and industrial development level, the MQT/MQS series pneumatic anchor drilling rig produced in China has been able to gradually replace the imported gear motor type anchor drilling rig; the ZYX series hydraulic anchor drilling rig has made gratifying progress in supporting the use of S100 roadheader.

 

The development of anchor drilling rig is very focused on the situation suitable for their own country, suitable for their own national engineering situation, so there are quite a lot of foreign anchor drilling rig types, they pay more attention to practicality. For example, American coal mines use a large number of tower drilling trucks, while French-made turret bolter drilling rigs set to drill holes. Finland produces drill truck-type bolter drilling rigs with resin injection systems. Each place has its own characteristics and creativity. Domestic anchor drilling rig has also been developed in the last ten years, of course, this is also closely related to the social and economic development, reform and opening up to the rapid economic development, for anchor drilling rig, down-the-hole drilling rig, drilling rig and other demand is also increasing, imports must face is expensive, which gave birth to a generation of Chinese anchor drilling rig talent.
