Description

Technical Field

[0001] The utility model relates to the field of belt conveyor auxiliary equipment, in particular to a mechanical deviation-correcting device for a belt conveyor. Background Art

[0002] Belt conveyors are widely used in industrial fields, such as cement and chemical industries. The smooth and reliable operation of the belt is critical, but during the operation of the belt, due to equipment manufacturing, installation, and uneven material distribution in the belt width direction, the belt will inevitably deviate. Severe deviation can directly lead to belt damage and paralysis of the equipment. For high-speed belt conveyors with high belt speeds, once the belt deviates and is not detected and corrected in time, it will cause belt damage, resulting in serious consequences. In some working conditions, there are no electrical or safety conditions to install an additional belt resetting power device, so it is necessary to propose a deviation correction device that does not require additional power.

[0018] The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

[0019] Example

[0020] As shown in the figure, a mechanical deviation correction device for a belt conveyor includes a fixed beam 7, a deviation detecting mechanism and a deviation correction mechanism. A connecting bridge 6 is provided in the middle of the fixed beam 7. The deviation detecting mechanism and the deviation correction mechanism are respectively provided at the upper two ends of the connecting bridge 6. The connecting bridge 6 spans over the fixed beam 7 and is fixed by screws. Bearings are provided at both ends of the connecting bridge 6.

[0021] The deflection analyzing mechanism includes a crank arm support frame and a steering link 15. The crank arm support frame includes a horizontal support 8, two oblique supports 9 and two telescopic supports 10. Belt contactors 11 are arranged at both ends of the top of the crank arm support frame. The oblique supports 9 are obliquely arranged at both ends of the horizontal support 8. The bottom end of the oblique support 9 is fixedly connected to the horizontal support 8 by screws. The installation angle between the oblique support 9 and the horizontal support 8 is not fixed, and the maximum angle can reach 145°, which can be adjusted according to the width and position of the belt.

[0022] A number of screw holes 20 are correspondingly arranged on the oblique bracket 9 and the telescopic bracket 10. The top of the oblique bracket 9 is fixedly connected to the telescopic bracket 10 by screws passing through the screw holes 20. The use of screw holes 20 at different positions for connection can change the extension length of the telescopic bracket 10 to adapt to belt conveyors of different sizes. The belt contactor 11 is arranged at the top of the telescopic bracket 10, and the two belt contactors 11 are arranged opposite to each other. The belt contactor 11 is a component that directly contacts the belt. When the belt deviates, force is applied to the belt contactor 11 on one side, driving the entire deflection detection mechanism to rotate.

[0023] The deviation correction mechanism includes a steering support bracket 1 and a belt idler, and a steering connecting plate 12 is arranged in the middle of the bottom surface of the steering support bracket 1. The belt idler is arranged above the steering support bracket 1 and is arranged parallel to the steering support bracket 1. The belt idler includes a horizontal idler and a left idler 2 and a right idler 4 arranged on both sides of the horizontal idler. The left end of the left idler 2 and the right end of the right idler 4 are respectively provided with a material stopper 5 with a gradually increasing diameter.

[0024] The middle part of the bottom surface of the horizontal bracket 8 is hinged to the right end of the steering link 15 through the first rotating shaft 17, the middle part of the bottom surface of the steering link 15 is hinged to the bridge member 6 through the second rotating shaft 18, the left end of the steering link 15 is hinged to the right end of the steering link plate 12 through the intermediate rotating shaft 19, and the left end of the steering link plate 12 is hinged to the bridge member 6 through the third rotating shaft 21. The bottom ends of the second rotating shaft 18 and the third rotating shaft 21 are both arranged in the bearing on the bridge member 6. The rotation direction of the left end of the steering link 15 is opposite to that of the right end, and the left and right ends of the steering link plate 12 have the same rotation direction. When the belt contactor 11 contacts the deviated belt, the deflection detection mechanism is deflected as a whole and rotates around the second rotating shaft 18. The left end of the rotating link pulls the steering link plate 12 to rotate the steering support bracket 1 in the opposite direction to the deflection detection mechanism, and realizes the return and reset of the belt through the material stopper 5.

[0025] A limiting unit is provided on the side of the deflection detection mechanism, and the limiting unit includes a fixed plate 16, a rotating connecting plate 13 and a limiting plate 14. The fixed plate 16 is fixed to the side of the horizontal bracket 8 close to the deflection correction mechanism, the right end of the rotating connecting plate 13 is fixedly connected to the fixed plate 16, the left end of the rotating connecting plate 13 is fixedly connected to the top of the limiting plate 14, and the bottom end of the limiting plate 14 is close to the side of the connecting bridge 6. When the crank arm support frame rotates counterclockwise toward the deflection correction mechanism, the limiting plate 14 is blocked by the connecting bridge 16 to prevent the crank arm support frame from colliding with the deflection correction mechanism.

[0026] Therefore, the utility model adopts a mechanical deviation correction device for a belt conveyor with the above-mentioned structure. The belt contactor 11 of the deviation correction mechanism is in contact with the belt. When the belt is deflected, the crank arm support frame rotates. Based on the linkage structure of the steering connecting rod 15-the connecting bridge member 6-the steering connecting plate 12, the steering support bracket 1 rotates in the opposite direction, and the belt is forced to return to the straight direction through the material blocking end 5 of the belt roller; the limiting unit in the deviation correction mechanism limits the excessive rotation of the crank arm support frame to prevent the crank arm support frame from colliding with the steering support bracket 1.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
