DETAILED DESCRIPTION

[0015] The present application will be further described in detail below in combination with the drawings.

[0016] The present application will be further described in detail below in combination with the drawings.Figure 1 、 Figure 2 、 Figure 3 The coal mine belt conveyor automatic deviation rectifying device comprises a conveyor body 1, a plurality of detection assemblies, and a deviation rectifying assembly. The conveyor body 1 comprises a base 4. A driving frame 5, a deviation rectifying frame 6, and a reversing frame 7 are sequentially arranged on the base 4 from left to right. A driving roller 8 is rotatably arranged on the driving frame 5. A plurality of U-shaped frames 9 and lower supporting rollers 10 are arranged on the deviation rectifying frame 6 and the reversing frame 7. V-shaped supporting rollers 11 are rotatably arranged in the U-shaped frames 9. The detection assemblies comprise a plurality of side columns 12. An inwardly inclined mounting plate 13 is arranged on the top of each side column 12. The detection assemblies are symmetrically arranged on both sides of the deviation rectifying frame 6 and the reversing frame 7. A belt deviation monitor 14 is arranged on the mounting plate 13. The deviation rectifying assembly comprises a tensioning mechanism for adjusting the lower supporting rollers 10 at the outer ends, and a rotating mechanism for adjusting the deflection of two U-shaped frames 9.

[0017] The belt deviation monitor 14 is attached with a photoelectric switch on the belt. When the belt is running, the photoelectric switch can detect the position and running state of the belt, so as to determine whether the belt is deviated. When the conveying belt deviates, the tensioning degree and position of the belt can be changed by adjusting the tensioning mechanism, so as to correct the deviation. When the conveying belt deviates from the theoretical center line, the axis of the V-shaped supporting roller 11 of the deviation rectifying device will be deflected by a certain angle around the rotation center in the corresponding direction, so as to generate a transverse friction force perpendicular to the running direction of the conveying belt between the roller and the conveying belt, so that the conveying belt returns to the correct position. The double adjustment cooperates with the detection assemblies to rectify the whole conveying belt.

[0018] The tensioning mechanism comprises a first hydraulic cylinder 15 and a sliding groove 16. The sliding groove 16 is symmetrically arranged on the inner side of one end of the reversing frame 7. A sliding block 17 is slidably arranged in the sliding groove 16. The hydraulic cylinder is arranged below the sliding groove 16 and is fixedly connected with the sliding block 17. The sliding block 17 is rotatably connected with the lower supporting roller 10.

[0019] The rotating mechanism comprises a second hydraulic cylinder 18 and a cross beam 19. The cross beam 19 is fixedly arranged on the top of the deviation rectifying frame 6. The tail end of the second hydraulic cylinder 18 is rotatably connected with the cross beam 19. The U-shaped frames 9 arranged on both sides of the deviation rectifying frame 6 are rotatably connected with the deviation rectifying frame 6 and are provided with a rotating shaft 20 on the lower side. The rotating shaft 20 is rotatably connected with the front end of the adjacent hydraulic cylinder.

[0020] Symmetrical support plates 21 are arranged on the lower sides of the U-shaped frames 9 arranged on both sides of the deviation rectifying frame 6. The lower ends of the support plates 21 are slidably connected with the deviation rectifying frame 6.

[0021] The interval of the V-shaped carrier rollers 11 on the deviation rectifying frame 6 is smaller than that of the V-shaped carrier rollers 11 on the reversing frame 7, and the V-shaped carrier rollers 11 on the deviation rectifying frame 6 are provided with a plurality of circular grooves 22, which can reduce the contact area between the V-shaped carrier rollers 11 on the deviation rectifying frame 6 and the conveying belt, and do not affect the material conveying, so as to reduce the friction, facilitate the rotation of the V-shaped carrier rollers 11 by a certain angle, and avoid that the too large friction between the V-shaped carrier rollers 11 and the conveying belt causes the deformation of the conveying belt.

[0022] When the belt deviation monitor detects belt deviation and cannot automatically correct, the first hydraulic cylinder is started to drive the sliding block to be finely adjusted downward in the sliding groove, and the lower carrier roller is moved downward to the conveying belt to be tightened and reset. The belt deviation monitor continues to detect, and if it cannot be reset, the sliding block position is restored. According to the deviation direction, the corresponding second hydraulic cylinder is started to drive the shaft and the U-shaped frame to deflect by a certain angle, a transverse friction force perpendicular to the running direction of the conveying belt is generated between the roller and the conveying belt, the conveying belt is returned to the correct position, and after reset, the initial state of the second hydraulic cylinder is restored.

[0023] The above describes the utility model and its implementation mode, which is not limited, and the drawings shown are only one of the embodiments of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired, without departing from the purpose of the utility model, without creative design, similar structure modes and embodiments of the technical scheme should belong to the protection scope of the utility model.
