Electrical variable measuring device for mining machinery motor

Abstract

The invention provides a mining machinery motor electrical variable measuring device, and relates to the technical field of electrical variable measurement, the mining machinery motor electrical variable measuring device comprises a base, the rear ends of the two sides of the base are fixedly provided with two side plates, the tops of the side plates are fixedly provided with a top plate, the bottom of the top plate is fixedly provided with two pressing blocks, and the front side corners of the bottoms of the pressing blocks are of a fillet structure; the air control device is fixedly arranged at the right end of the rear side of the rear plate; the air control device comprises a lead screw frame, the lead screw frame is fixedly arranged at the top of the air control device, and a lifting lead screw is rotationally arranged in the middle of the lead screw frame; according to the air control device, the air pressure measurement variable can be adjusted, the lifting lead screw is rotated to drive the square piston to ascend and descend, air control is carried out, the internal air pressure of the housing is adjusted, and electric variable measurement of the motor under the influence of air pressure is achieved. The technical scheme of the invention is used for solving the problem that a currently used measuring device is difficult to measure a plurality of factors causing the change of the power consumption of the motor at the same time.

Description

technical field [0001] The invention relates to the technical field of electric variable measurement, in particular to an electric variable measuring device for mining machinery motors. Background technique [0002] The working principle of the motor is to drive the starter rotor to rotate through the energized coil in the magnetic field. When using in mines, it is necessary to consider the temperature of the motor, the change of air pressure at the working place, the interference of the magnetic field at the place of use and the influence of the load on the motor. All of the aforementioned influencing factors may cause the power consumption of the motor to change. [0003] However, the measuring devices currently used are difficult to measure the above problems at the same time. They do not have the function of directly adjusting the air pressure to measure electrical variables, do not have the function of adjusting the magnetic field to interfere with the operation of the ...
