Now understand the principles supporting bolt, then let us introduce installation works under the bolt. Bolt installation ① check: Before installing the bolt, to check the direction of drilling, location, angle, depth, anchoring agent, anchor meets the design requirements, if a failure, it may not be installed. ② anchor head Mixing: timely kick after eye bolt installation requires a minimum operating by two. When installing anchors, the first connector is screwed onto the threaded bolt tail, with the other rod to the bottom of the hole will be anchoring agent pier real, then the placement of coal drill or blender, start mixing, stirring anchor time is 30 to 40 seconds. To force uniform stirring resin bolt tension meter, not excessive. When taking coal drill, lift the rod body, after removing temporarily with small pieces of wood or small stones placed in the hole and choked rod to prevent the rod decline. ③ pallet install: to be solidified resin, and then remove the connector, and immediately install pallet, gaskets, when the bolt tension meter Guangdong install pallet, the pallet must be lifted by one person anchor set into care live, another person quickly put gaskets, screw on the double nut, the roadway is high need another person with a long bar against the pallet to prevent fall injuries. Require close pallet wall, double cap single pad tighten security or anti prohibited pallets padded coal rock. Finally, with a torque wrench to tighten the nut Hubei double bolt tension meter, so that to reach 90 percent of prestressed anchoring force. Turn from the outside and inside, playing a note one, all empty top support is completed. Bolt must be tightened with a torque wrench tight mechanical or ensure that pallets closely wall. Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City, relying on technological advantage Resources and Environmental Engineering, University of Science and Technology, to develop the production and operation of coal mine safety monitoring instruments for the main direction of Henan bolt tension meter, and actively carry out the conversion work of the new technology, technological innovation and new product development ability. Technical staff, mostly Shandong University of Science and Technology professor, associate professor and the backbone of the research staff, with 20 years of mining experience in product development and production pressure. Usage: mining bolt tension meter is used to detect, judge shotcrete support projects dedicated equipment anchor strength, anchoring force, anchoring quality. Features: Mine rational use pointer bolt tension meter structure, reliable performance, and hand pumps, electric pumps, pneumatic pumps supporting the use. Bolt tension meter, good Henan bolt tension meter, quality and excellent service provided by Warner electromechanical. This information consists of: Mechanical and Electrical Equipment Co., Ltd.
