[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides Figure 1-Figure 3 The coal mine belt anti-deviation device shown includes a bracket 1, an upper deviation correction mechanism 5, and a lower deviation correction mechanism 6. A connecting crossbar 2 is fixedly installed on the top of the bracket 1. The connecting crossbars 2 are symmetrically arranged on the bracket 1. Upper deviation control structures 3 are symmetrically arranged on the connecting crossbars 2. Two lower deviation control structures 4 are fixedly installed at one end of the bracket 1.

[0020] See also Figure 1 When the coal mine belt needs to be prevented from deviation, the bracket 1 is firmly installed at the appropriate position of the coal mine belt conveyor system to ensure its stability, the connecting cross bar 2 is welded to the top of the bracket 1, and the connecting cross bar 2 is ensured to be symmetrically distributed on the bracket 1. Then, the upper deviation control structure 3 is installed on the connecting cross bar 2, and the lower deviation control structure 4 is installed at one end of the bracket 1. The upper deviation correction mechanism 5 is movably installed on the connecting cross bar 2 so that it can perform effective deviation correction operations when the belt deviates upward. Finally, the lower deviation correction mechanism 6 is installed so that the lower deviation correction mechanism 6 can be adjusted according to actual conditions to ensure that it can effectively correct the deviation problem of the lower belt.

[0021] The upper deflection-correcting mechanism 5 includes an upper deflection-correcting bracket 501, both ends of which are movably mounted on the connecting crossbar 2. A guide roller 503 is rotatably mounted on the upper deflection-correcting bracket 501, and a pneumatic cylinder 502 is movably mounted on one side of the connecting crossbar 2. The output end of the pneumatic cylinder 502 is movably connected to one end of the upper deflection-correcting bracket 501.

[0022] See also Figure 1-Figure 2 When the upper belt on the upper correcting mechanism 5 deviates, the pneumatic cylinder 502 pushes the upper correcting bracket 501 to rotate on the connecting cross bar 2, thereby changing the position of the guide roller 503, so that the belt deflection returns to the right position to correct its deviation trend.

[0023] The lower correcting mechanism 6 includes a lower correcting bracket 601, which is fixedly connected to the connecting cross bar 2. The lower correcting bracket 601 is "U"-shaped. A fixed base 605 is fixedly installed at the center of the lower correcting bracket 601, and a mounting base 604 is movably installed on the fixed base 605. A second guide roller 603 is rotatably installed on the top of the mounting base 604. The second guide roller 603 is fixedly connected to the connecting rods at both ends of the mounting base 604. A second pneumatic cylinder 602 is fixedly installed on the inner side wall of the lower correcting bracket 601, and the output end of the second pneumatic cylinder 602 is movably connected to the connecting rod at one end of the mounting base 604.

[0024] See also Figure 1 、 Figure 3 When the belt on the lower correcting mechanism 6 deviates, the mounting seat 604 rotates on the fixed base 605 through the pushing action of the pneumatic cylinder 2 602, thereby causing the guide roller 2 603 to slightly flip, and the belt on the guide roller 2 603 deviates back to the right position to correct its deviation trend.

[0025] An upper deviation control structure 3 is provided with an upper deviation correction switch 301, a sensor 1 302 is fixedly mounted on the upper deviation control structure 3, and the upper deviation control structure 3 is electrically connected to the upper deviation correction mechanism 5. A lower deviation control structure 4 is provided with a lower deviation correction switch 401, a sensor 2 402 is fixedly mounted on the lower deviation correction switch 401, and the lower deviation control structure 4 is electrically connected to the lower deviation correction mechanism 6.

[0026] See also Figure 1 During the sliding process of the belt in the anti-deviation device, the sensor 1 302 on the upper deviation control structure 3 and the sensor 2 402 on the lower deviation correcting switch 401 monitor whether the belt is still on the correct track, and then transmit the signal to the upper deviation control structure 3 and the lower deviation correcting switch 401 in the form of an electrical signal. After receiving the signal, the upper deviation correcting switch 301 and the lower deviation correcting switch 401 are controlled to open, so that the upper deviation correcting mechanism 5 and the lower deviation correcting mechanism 6 start to operate, so that the deviated belt returns to the right track to correct its deviation trend.

[0027] The working principle of the present invention is as follows: when the upper part or the lower part of the belt deviates, the sensor 1 302 on the upper deviation control structure 3 or the sensor 2 402 on the lower deviation control structure 4 monitors the belt deviation and transmits the signal to the upper deviation control structure 3 or the lower deviation control structure 4 in the form of an electrical signal. The upper deviation control structure 3 controls to open the upper correction switch 301 and start the upper correction mechanism 5, or the lower deviation control structure 4 controls to open the lower correction switch 401 and start the lower correction mechanism 6. The pneumatic cylinder 1 502 in the upper correction mechanism 5 or the pneumatic cylinder 2 602 in the lower correction mechanism 6 pushes the upper correction bracket 501 or the mounting seat 604 to rotate, thereby driving the guide roller 1 503 or the guide roller 2 603 to rotate and change position, so that the upper and lower belts are offset and returned to normal, correcting their deviation trend.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
