Embodiment Construction
[0019] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.
[0020] The magnetic pole switch combination structure of the traction motor of the coal mining machine, the magnetic pole switch is arranged in the speed measuring junction box of the traction motor of the coal mining machine goaf side, and the output end of the motor shaft here is evenly distributed with a number of grooves. The magnetic pole switch is arranged at the output end of the motor shaft of the traction motor to detect the motor speed, and the speed measuring junction box can realize the protection of the magnetic pole switch. This design is relatively easy to implement, the magnetic pole switch is small in size and takes up little space; 5 grooves are evenly distributed on the output shaft of the motor (the 5 grooves evenly distributed and the naturally formed protrusions are to produce a stable switch. Continuous signal, and achieve ac...

The invention belongs to the monitoring of the running position of a coal mining machine, in particular to a composite structure of a magnetic pole switch of a traction motor for a coal mining machine, which solves the problems that the traditional coal mining machine has no position monitoring or has undesirable installation position, has complicated structure, frequent damage in use, low measuring precision, and false installation, and even become a new failure source. The composite structure of the magnetic pole switch of the traction motor for the coal mining machine is characterized in that the magnetic pole switch is arranged in a speed-measuring junction box of the traction motor at the worked-out side of the coal mining machine, and the output end of a motor shaft at the traction motor is uniformly distributed with a plurality of grooves. The invention has the advantages that the measuring precision of the composite structure can be enhanced, the structure can be simplified and compacted and has convenient maintenance and low manufacturing cost, and the magnetic pole switch is easy to protect so that the using reliability is enhanced.
Description
technical field [0001] The invention belongs to coal mining machine parts, in particular to a coal mining machine traction motor magnetic pole switch combination structure. Background technique [0002] As the key equipment of the working face, the coal shearer only has strong support in the remote transmission technology of operation data and position detection technology. Under this premise, it is possible to realize the detection and management of the operation data of underground equipment on the ground, and even realize centralized control ( or monitoring). At present, various electric traction shearers in foreign countries have made great progress in intelligent detection and control. Various operating parameters of the shearer can be detected and displayed, and centralized control of the operation of the shearer can be realized. Due to the relatively poor conditions of the underground working face, the monitoring and control parameters are required to be as comprehen...
