Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of torque detection, and particularly relates to a mechanical torque detector for installation pre-tightening force of a magnetic medium plate of a magnetic separator. BACKGROUND

[0002] As a widely used ore dressing equipment in mining, metallurgy and other industries, the magnetic separator has a core component, i.e., a magnetic medium plate, which plays a key role in realizing efficient magnetic separation. The magnetic medium plate is tightly installed at a specific position of the magnetic separator through bolts, and the installation quality directly affects the performance and stability of the magnetic separator. The bolt connection not only needs to ensure that the magnetic medium plate does not loosen and fall off due to vibration, impact and other factors during the operation of the equipment, but also needs to ensure that the magnetic medium plate has good contact and sealing performance with other components of the magnetic separator, so as to maintain the normal working magnetic field and material passing environment of the magnetic separator. Therefore, the bolts used for the installation of the magnetic medium plate need to be detected by a torque detector.

[0003] A Chinese patent with the publication number CN119147137A discloses a low-resistance bolt torque detector. After the installation block is installed in place, the piston plate is moved downward in the pressure groove by the magnetic attraction between the first magnetic block and the second magnetic block, so that the lubricating oil in the pressure groove is sprayed from the smearing nozzle through the second connecting pipe, thereby smearing the lubricating oil to the outside of the bolt body, avoiding the excessive friction between the bolt body and the locking nut affecting the torque detection accuracy.

[0004] However, in the above scheme, after the torque detection of one bolt is completed, the detector needs to be disassembled from the bolt, and then the detector needs to be reinstalled on the next bolt to be detected for detection. Such frequent disassembly and reinstallation operation not only consumes a lot of time and labor, but also increases the complexity and error probability of the operation, resulting in low detection efficiency of the equipment.

[0005] Therefore, the application provides a mechanical torque detector for installation pre-tightening force of a magnetic medium plate of a magnetic separator. SUMMARY
