Embodiment Construction
[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the following embodiments will specifically describe the monitoring and alarm system and method for online monitoring of cutter head fracture in the cutter drum of the present invention in conjunction with the accompanying drawings.
[0020]
[0021] This embodiment provides a monitoring and alarm method for online monitoring of the breakage of the cutter head in the cutter drum, which is performed according to the following steps.
[0022] Step 1: Use magnetic material to make the cutter head;
[0023] Step two, install the magnetic cutter head obtained in step one on the drum;
[0024] Step 3: Set up a cover on the outside of the knife drum, and set a magnetic induction proximity switch on the cover, and obtain the change of the magnetic field.
[0025] Step four, according to the change of the magnetic field, judge whether there is a fracture of the ...

The invention provides a monitoring-alarming system and method for monitoring the breakage condition of a tool bit in a tool drum online. The monitoring and alarming method for monitoring the breakagecondition of the tool bit in the tool drum online is characterized by comprising the following steps: 1, manufacturing the tool bit from a magnetic material; 2, installing the magnetic tool bit obtained in the step 1 is on the tool drum; 3, arranging a housing outside the tool drum, arranging a magnetic induction type proximity switch on the housing, and obtaining the magnetic field change condition; 4, judging whether the tool bit is broken or not according to the change condition of the magnetic field, and 5, giving an alarm for reminding when the tool bit is judged to be broken. Accordingto the monitoring and alarming system for monitoring the breakage condition of the tool bit in the tool drum online, a user can know the breakage condition of the tool bit immediately and replace thetool bit in time.
Description
Technical field [0001] The invention relates to the field of machinery, and in particular to a monitoring alarm system and method for online monitoring of the cutter head fracture condition in the cutter drum. Background technique [0002] The knife drum is an important part of heavy machinery such as milling equipment, crushing equipment, and cutting equipment. Milling, crushing, and cutting are realized through the knife drum. During work, the cutter head may break, and it needs to be replaced in time. However, the current treatment method is: after the mechanical equipment is finished, manually observe the fracture and damage of the cutter head. In this way, the breakage of the cutter head cannot be found in the work, and if the cutter head is not broken in the first time, it will cause serious adverse effects on the subsequent work. Moreover, this method needs to check the cutter heads on the knife drum one by one, which is time-consuming and labor-intensive for manual main...
