Bolt tension meter in front of the steps to prepare anchor pulling force test have? ? ① According to the test purpose, in the coal mine (tunnel) to develop parts of the rock drill bolt holes. Deep hole depth on the basis of normal minor adjustments to the length of the exposed bolt bigger ensure Rally jack bolt installation; or using a normal hole depth will be tested bolt lengthened, so as to jack bolt tension meter installation provide space. ② according to the normal installation process to install the test bolt, the bolt with mortar smooth mouth to put pressure support plate. ③ determined according to the type and drawing time test purposes bolt. ④ bolt tail plus the plate, put a hollow jack, anchor the outer end of the inner cylinder jack fastened together, and the installation of displacement measuring equipment and instruments. ⑤ by manual hydraulic pump pressurized oil from the oil pressure gauge reading, according to the translation of the piston area anchor withstand the pulling force, depending on the amount required to read from the dial gauge ending displacement bolt, bolt drawing draw force-displacement curve Yantai bolt tension meter for analysis. Prestressed anchor supporting quality Electrical Equipment Co., Ltd. Tai'an City of Warner special production of prestressed detection tensioning equipment, bolting construction, testing equipment: bolt tension meter, anchor dynamometer, Bolt Cutter , measuring bolt, bolt installation machine, bolt preload detector, mine gas trigger, bolt pneumatic wrenches, bolt torque wrench, special extension socket head, bolt angle detector, nut off , a force sensor bolt, bolt dynamometer tester, bolt torque amplifier, hydraulic bolt wrench, auxiliary equipment: Mining track gas drilling, pneumatic orbital drilling machines. 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, position, angle, depth, anchoring agent, anchor meets the design requirements, if a failure, it can not be installed. ② anchor head Mixing: After eye bolt kick timely installation requires a minimum operated by two people. When installing anchors, the first connector is screwed onto the threaded bolt tail Weifang bolt tension meter, with the other rod to the bottom of the hole will be anchoring agent pier real bolt tension meter, then the placement of coal drill or agitation , a stirring was started, anchor stirring time of 30 to 40 seconds. Stir resin to force uniform, not too much. When taking coal drill, lift up the rod, after removing temporarily with small pieces of wood or small stones placed in the wells choked rod to prevent the rod decline. ③ pallet install: After the resin solidified, and then remove the connector, immediately install pallet, gaskets, when install pallet, the pallet to be lifted by one person hold the anchor set into another person quickly put on pads, tighten the nut on the double, the higher the roadway when another person needs to withstand the pallet with a long bar to prevent fall injuries. Requires close pallet wall, double cap single pad tighten security or anti prohibited pallets padded coal blocks. Finally, with a torque wrench to tighten the nut double that of prestressed anchoring force of up to 90%. Turn from the outside and Li Weihai bolt tension meter, playing a note one, will support all the empty top finish. Bolt must be tightened with a torque wrench tight mechanical or ensure close pallet wall.
