Description
Technical field
The utility model relates to a kind of mud scraper, particularly relates to a kind of dense mud scraper overload protection device.
Background technology
Thickening machine main is with applying to environment protection sewage process; mine ore dressing is collected; material will be precipitated to central collection; because of the more difficult control of sediment doses; easily go out and bury collecting rake below; initial design adopts and surveys current system by intelligence instrument, collection rake is upwards promoted by lifting motor work, thus makes dense mud scraper obtain protective effect.
In prior art, after adopting measured motor electric current that current value is exceeded standard, lifting motor work occurs that the probability of error is very large, thus fault rate is very high.Such as voltage change, variation of ambient temperature, component ageing etc. all easily cause a deviation.
Utility model content
The utility model is intended to address the aforementioned drawbacks, and provides a kind of dense mud scraper overload protection device.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical problem adopts: this dense mud scraper overload protection device comprises reductor, the lifting motor that reductor side connects, shaft is connected bottom lifting motor, be provided with between lifting motor and shaft and stir supporting and stir supporting case lid, the bottom of shaft connects agitator one and agitator two, the upper end of reductor is provided with second level reductor, the lower end of reductor is provided with third level decelerating chassis, the upper end of second level reductor connects first order reductor, be provided with moment of torsion between the side of described first order reductor and the side of second level reductor and support transmission arm and torque sensor, lower end and the moment of torsion of torque sensor support transmission arm and are fixedly connected with, the upper end of torque sensor is fixedly connected with the side of first order reductor.
According to another embodiment of the present utility model, comprise described third level decelerating chassis, stirring supporting and shaft further and be fixedly connected on bracing frame.
The beneficial effects of the utility model are: can monitor the stressing conditions collecting rake at any time after this dense mud scraper overload protection device adopts torque sensor; if turn round when short square raises and illustrate that material increases below; can reduce or stop charging in concentrator, avoid the regular lifting of lifting motor.Not only effectively reduce equipment failure rate, by us, the real-time monitoring of moment of torsion is substantially increased to the service efficiency of our equipment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of partial enlargement in Fig. 1;
Wherein: 1, reductor, 2, lifting motor, 3, supporting case lid is stirred, 4, supporting is stirred, 5, shaft, 6, agitator one, 7, agitator two, 8, first order reductor, 9, torque sensor, 10, moment of torsion supporting transmission arm, 11, second level reductor, 12, third level decelerating chassis, 13, bracing frame.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, figure comprises reductor 1, the lifting motor 2 that reductor 1 side connects, shaft 5 is connected bottom lifting motor 2, be provided with between lifting motor 2 and shaft 5 and stir supporting 4 and stir supporting case lid 3, the bottom of shaft 5 connects agitator 1 and agitator 27, the upper end of reductor 1 is provided with second level reductor 11, the lower end of reductor 1 is provided with third level decelerating chassis 12, the upper end of second level reductor 11 connects first order reductor 8, be provided with moment of torsion between the side of first order reductor 8 and the side of second level reductor 11 and support transmission arm 10 and torque sensor 9, lower end and the moment of torsion of torque sensor 9 support transmission arm 10 and are fixedly connected with, the upper end of torque sensor 9 is fixedly connected with the side of first order reductor 8, third level decelerating chassis 12, stirring supporting 4 and shaft 5 are fixedly connected on bracing frame 13.
Embodiment
Survey Main motor current when normal work, its value is set to canonical parameter.
When torque sensor survey Main motor current be above standard arrange electric current a certain size time, be namely likely that mud precipitation in mud scraper bottom is too many or bottom is stressed too large, main stirrings stopping certain hour, lifting motor upwards promotes and starts working.When torque sensor survey Main motor current be less than standard configuration electric current a certain size time, be namely likely that mud precipitation in mud scraper bottom is too many or bottom is stressed too large, main stirrings stopping certain hour, lifting motor upwards declines and starts working.
First order reductor is designed to hollow shaft, coordinates with second level reductor power shaft (convex axle).Second level reductor arranges moment of torsion supporting transmission arm (start and support first order reductor), torque sensor is contained between first order reductor and torque sensing arm.When equipment operation, torque sensor will bear the anti-power of work, and torque sensor is started working, if torque sensor numerical value also increases when dense mud scraper lower load increases, if sensor exports and turns a sense signal and make lifting motor work when moment of torsion exceedes setting value.
