  Introduction of Constant Torque Electric Spanner for Bridge Construction随着中国改革开放的不断深入,中国的基础设施越来越多,桥梁建设是必不可少的。系索桥是桥梁建设的主要形式。螺栓连接必须采用大六角高强度螺栓。
  With the deepening of China's reform and opening up, China's infrastructure is increasing, and bridge construction is indispensable. Tethered bridge is the main form of bridge construction. Large hexagonal high strength bolts must be used in bolt connection.
  大六角高强度螺栓一般为10.9级或12.9级。根据高强螺栓的施工工艺要求,高强螺栓的施工必须先紧固,再紧固。初始拧紧一般为比较大扭矩值的50% ~ 60%;比较后的紧固必须达到螺栓规定的比较大扭矩值。
  Large hexagonal high strength bolts are generally of grade 10.9 or 12.9. According to the construction technology requirements of high-strength bolts, the construction of high-strength bolts must be tightened first and then. Initial tightening generally ranges from 50% to 60% of the maximum torque value; final tightening must reach the maximum torque value specified by the bolt.
  Large hexagonal high strength bolt structure, the first tightening can choose manual torque wrench, fixed torque electric wrench, the last tightening must choose the front field torque electric wrench.
  In bridge construction, bolts are usually M2-M24 and (large hexagonal high strength bolts, including M2-M24 maximum torque value is usually 860 nautical miles (maximum torque value is based on different friction coefficients, and different), (maximum torque value is usually 1700 nautical miles (maximum torque value is based on different friction coefficients, and different) early tightening, it is necessary to select torque electric wrench, set initial tightening moment value, and start to tighten bolts. After a few seconds, stop fastening the electric wrench and take out the sleeve.
  Finally, when tightening, it is necessary to fix the torque electric wrench. First, the value of the torque is set to the maximum value of the bolt. After tightening for a few seconds, the electric wrench stops tightening and can be taken out.
  The universal fixed moment electric wrench can be used in the initial tightening, and the front field fixed moment electric wrench must be used in the final tightening. The torque is large, the error is small and the precision is high.
  (1) Firstly, the dial is set to the required torque value, and the wrench glove is placed on the bolt.
  Press the switch and start working.
  (3) When the wrench reaches the set torque value, it automatically stops tightening and pulls out the wrench to finish the work.
  Use note:
  Please strictly comply with the regulatory requirements.
  Insert the bolt into the sleeve reasonably and smoothly without tilting, so as to prolong the service life of the sleeve.
  Replace the carbon brushes in time. The carbon brushes should not be less than 6mm in order to prolong the service life of the motor.
  Don't tighten it repeatedly.
  Do not touch the reaction arm while working.
  To adjust the positive and negative rotation, it is necessary to rotate the trigger in place.
  When the green light is on, it is usually on and can work properly.
  When the red light is on, the operation is illegal and the power supply needs to be restarted.

  2. Install the necessary sleeve.
  3. Tighten two positioning screws.
  Replace the carbon brush:
  (1) Remove the brush cover and put the carbon brush into it.
  Press in the spring.
  (Long to short, short to long)
  Upper chord (don't exert too much force).
  Regular inspection and maintenance:
  1. 定期检查电源线。
  1. Check the power cord regularly.
  2. 定期检查各部位螺丝,注意电机的声音。
  2. Check the screw in every part regularly and pay attention to the sound of the motor.
  3. Ensure that motor, sleeve and machine are free from impurities.
  4. 拧紧螺栓5000次,及时检查炭刷和套管。
