The invention discloses an electric head torque checking device. The electric head torque checking device comprises a torque verifying platform control cabinet and torque verifying platform vehicle bodies connected with the torque verifying platform control cabinet. Each torque verifying platform vehicle body comprises a shell and a universal stacking type flange assembly arranged on a platform on the top of the shell, wherein the lower portion of the universal stacking type flange assembly is connected with a sensor, a coupler and a speed changing box, and the two sides of the speed changing box are provided with speed changing box load assemblies. Each speed changing box load assembly comprises a magnetic powder brake. The periphery of each torque verifying platform vehicle body is provided with an adjusting hand wheel. The torque verifying platform vehicle bodies with different ranges can be connected with the torque verifying platform control cabinet, torque checking on different specifications of electric heads can be achieved, the different electric heads can be clamped conveniently and rapidly through the universal stacking type flange assemblies, and butt joint between the electric heads and the universal stacking type flange assemblies is facilitated through the adjusting hand wheels. The electric head torque checking device is convenient to operate, stable, reliable and suitable for carrying out torque checking on the different specifications of electric heads.
Description
technical field [0001] The invention relates to the technical field of electric head torque calibration, in particular to an electric head torque calibration device. Background technique [0002] The electric heads used in nuclear power plants have many varieties (different production countries and factories), various specifications, torque ranges, electrical control methods, mechanical installation interfaces, and working environments are all different. After routine maintenance and overhaul disintegration, it is necessary to use a special torque calibration device to reset the key parameters such as the control torque of the electric head, restore the technical data, and establish the management database of the electric head. [0003] The existing electric head detection instrument has the following limitations: single torque range, narrow application range; indirect torque measurement method, low precision; fixed installation is not movable, not suitable for production si...
