As shown in fig. 1-5, the self-balancing mining scraper conveyor comprises a conveying box body 1, chains 2 at the left side and the right side of the conveying box body 1, scrapers 3 uniformly arranged between the chains 2 at the two sides, and a main motor 4 arranged at the lower part of the front side of the conveying box body 1; the method is characterized in that: the output end of the main motor 4 is connected with a differential 5; the differential 5 comprises an input shaft 6, a phase control port and output shafts 7 at the left side and the right side; an input shaft 6 of the differential 5 is connected with an output shaft 7 of the main motor 4, and the output shafts 7 on the left side and the right side are connected with self-swinging adjusting devices; the self-swinging adjusting device comprises a central disc 8 connected with an output shaft 7 of the differential mechanism 5 and a chain wheel 9 coaxially sleeved outside the central disc 8; the side surface of the central disc 8 is uniformly and fixedly connected with an elastic body 10 along the annular shape; the other end of the elastic body 10 is fixedly connected with the inner side surface of the chain wheel 9; the chain 2 is meshed and matched with the chain wheel 9; an infrared distance measuring sensor module 11 is arranged on the lower part of the inner side wall of the transportation box body 1; distance measuring rods 12 corresponding to the detection end of the infrared distance measuring sensor module 11 are vertically fixed on the left side and the right side of the upper end of the scraper 3; the signal output end of the infrared distance measurement sensor module 11 is connected with a phase control port of the differential 5 through a controller; a support rod 13 is arranged on the inner side surface of the chain wheel 9; the end part of the supporting rod 13 is provided with a stop trigger switch 14 connected with a control circuit of the main motor 4, and the stop trigger switch 14 is opposite to one elastic body 10; the infrared sensor module is connected with a timing module.
As shown in figure 1, when the invention is used, whether the teeth are dislocated or not can be judged by observation of workers, when the teeth are dislocated, the chain wheels 9 at two sides can be independently controlled through the phase control port of the differential mechanism 5, so that one side which rotates relatively fast (relative dislocation caused by the teeth are dislocated) stops rotating, and after the other side which rotates relatively slow continues to rotate the dislocated phase, the two sides keep balance again, then the control of the differential mechanism 5 is released and the two sides are locked, and the chains 2 at two sides run synchronously;
as shown in fig. 3, when the output shaft 7 of the differential 5 drives the self-oscillating adjusting device to rotate, the central disc 8 drives the chain wheel 9 to rotate through the elastic body 10, the central disc 8 first drives the elastic body 10 to rotate and deform, when the elastic body 10 deforms to a certain degree, the relative torque is transmitted to drive the chain 2 to rotate, the scraper 3 is driven to move by overcoming the resistance, if the tension of the chains 2 at both sides is stable, the whole body operates stably, when the coal blocks are accumulated at one side, taking the left side as an example, the required tension of the chain 2 at the left side is increased, when the central disc 8 rotates continuously, the elastic body 10 is driven to continue deforming, the chain wheel 9 at the left side is not moved, when the elastic body 10 deforms soon and transmits enough torque to continue to drive the chain wheel 9 to rotate, the chain 2 at the left side pauses a little and then continues to move, the time is short, meanwhile, the chain, due to the pause of the left side chain 2, the right side chain 2 drives the right side of the scraper 3 to move forwards for a small distance, the scraper 3 is inclined, the heavier left side is backward, the left side does not work backward during pause, the right side chain 2 bears larger pulling force, the right side elastic body 10 deforms to store energy, pause gaps are generated, the left and right pause gaps are staggered in time, the left side moves forwards when the left side pauses slightly, the left side moves forwards when the right side pauses slightly, the scraper 3 can swing, the coal briquette can move to the middle position due to slight swinging, accumulation on one side is avoided, and finally the zippers on two sides run stably.
In the self-oscillation adjusting device, the blade 3 oscillates less due to a short time lag, but the blade can be pushed to the center, and the differential 5 is not adjusted when the inclination due to the self-oscillation is within the range of the degree of the dislocation or when the self-oscillation is adjusted.
As shown in fig. 4, when the infrared distance measuring sensor module 11 measures the distance between the distance measuring rods 12, the distance measuring rods 12 are arranged on the left side and the right side of each scraper 3, the linear distance between the two distance measuring rods 12 is fixed, when the distance measuring rods are inclined, the vertical distance between the distance measuring rods 11 and the detection end of the infrared distance measuring sensor module 11 is changed, the distance between the two distance measuring rods 12 and the detection end of the infrared distance measuring sensor module 11 is measured, one distance is near the other distance, the vertical distance between the two distance measuring rods 12 can be obtained by difference, the vertical distance is a right-angle side, the linear distance is an inclined side, the inclined angle can be calculated by a processor arranged in the module, and. The infrared distance measuring sensor module 11 is installed at the lower part of the inner side wall of the transportation box body 1, the lower scraper 3 is detected, taking the example that the left side of the lower scraper 3 inclines backwards, the distance of the distance measuring rod 12 at the left side is detected firstly, the distance is far, namely, the left side of the scraper 3 is judged to be backwards, the distance of the distance measuring rod 12 at the right side is detected by the infrared distance measuring sensor module 11, the inclination angle can be obtained through built-in processing calculation, the inclination angle is judged to be caused by the malocclusion when reaching a certain value, the left side of the lower scraper 3 is backwards, in fact, the motion process is due to the advance of the motion, the controller can control the output shaft 7 at the left side of the differential mechanism 5 to stop rotating through the phase control port, meanwhile, the output shaft 7 at the right side, the controller is used for controlling the rotation angle of the main motor 4. When the tooth is dislocated, the scraper 3 is inclined greatly, and the detected tooth is firstly detected to enter the adjustment stage of the differential 5 without self-swinging adjustment.
Through the range finding distance of infrared distance measuring sensor module 11 to range finding pole 12, can judge whether left range finding pole 12 or right side range finding pole 12, through the time interval size, can judge that is same scraper blade 3 or two adjacent scraper blades 3, then use the range finding signal as the timing point, the moving time of every section of detectable both sides chain 2, when moving time interval grow, then this section chain 2 probably has loosened.
As shown in fig. 5, the differential 5 may be electronic or mechanical, and the electronic differential 5 needs a master controller to connect the main motor 4, the phase control port, the infrared distance measuring sensor module 11, the timing module, and the like; the mechanical differential 5 needs to be matched with a display to connect the infrared distance measuring sensor module 11 and the timing module so that a worker can operate the control circuit of the main motor 4 and the differential 5 after observing the detection result.
