Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment anti-deviation, in particular to an anti-deviation device for conveying equipment. Background Art

[0002] Conveying equipment is a mechanical device for continuously conveying materials. It is widely used in mining, metallurgy, chemical industry, ports, and other industries. It realizes automatic material transportation through conveyor belts, chains, rollers or spiral structures, improves production efficiency and reduces labor costs. According to different conveying methods, conveying equipment mainly includes belt conveyors, chain conveyors, roller conveyors, screw conveyors, etc. Among them, belt conveyors have become one of the most common conveying equipment due to their strong conveying capacity and wide adaptability. During the operation of conveying equipment, conveyor belt deviation is a common problem. Conveyor belt deviation will lead to reduced conveying efficiency, material scattering, equipment damage, and even safety accidents. Therefore, the anti-deviation device has become an indispensable auxiliary mechanism in conveying equipment, which can automatically correct the conveyor belt when it deviates, so that it remains on the normal operating track and ensures the stability and safety of the conveying system.

[0003] At present, the common anti-deviation devices mainly correct the deviation through the V-shaped distribution of rollers and the rotatable roller frame: multiple rollers are arranged at a V-shaped angle so that the conveyor belt is subject to an inward constraint force, reducing the possibility of deviation; the roller frame can rotate when the conveyor belt deviates, and rely on the friction of the conveyor belt itself to adjust the conveyor belt to return to the right position; although it can also play a certain anti-deviation role, because the V-shaped rollers only generate centripetal constraint force through a fixed angle, the rotatable roller frame only relies on the friction force after the conveyor belt is deviated to trigger rotation, both belong to a one-way deviation correction mode, and cannot be dynamically adjusted according to the deviation direction and degree. The deviation correction effect is single and the adjustment range is limited, which cannot effectively solve the conveyor belt deviation under complex working conditions. Summary of the invention

[0004] The present invention provides an anti-deviation device for conveying equipment, which solves the problem that the current common anti-deviation device mainly corrects the deviation through a V-shaped roller arrangement and a rotatable roller frame, but the V-shaped roller only relies on a fixed angle to apply a centripetal constraint force, and the rotatable roller frame relies on the friction force after the conveyor belt is offset to trigger rotation, both of which belong to a one-way deviation correction mode and cannot be dynamically adjusted according to the deviation direction and degree, resulting in a single deviation correction effect and a limited adjustment range, and it is difficult to effectively deal with the technical problem of conveyor belt deviation under complex working conditions.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 8 The present invention provides a technical solution: an anti-deviation device for conveying equipment, comprising a plurality of H-shaped support frames 1 distributed equidistantly in the transverse direction, two strip-shaped supports 2 symmetrically fixedly connected to the H-shaped support frames 1, a plurality of roller frames 3 equidistantly fixedly connected to the two strip-shaped supports 2 and having U-shaped end faces, and a roller group 4 installed on the roller frames 3, each roller frame 3 is symmetrically installed with two anti-deviation mechanisms 5 for restricting the conveyor belt in the transverse direction to prevent the conveyor belt from deviating, a correction mechanism 6 for restricting the conveyor belt from above and automatically correcting it in time is arranged on the two strip-shaped supports 2 and between two adjacent anti-deviation mechanisms 5, the anti-deviation mechanism 5 and the correction mechanism 6 are arranged between the two adjacent anti-deviation mechanisms 5, and the anti-deviation mechanism 5 and the correction mechanism 6 are arranged between the two adjacent anti-deviation mechanisms 5. The deflection mechanisms 6 are interconnected to impose restrictions on the conveyor belt from multiple directions to prevent the conveyor belt from running off track. An F-shaped fixed frame is fixedly connected to the upper part of the vertical section of the roller frame 3, and a stop roller 8 is rotatably connected to the fixed frame. A number of sliding grooves 10 are equidistantly provided on the opposite sides of the two strip-shaped supports 2, and sliding blocks are slidably connected in the sliding grooves 10, and a compression spring is fixedly connected between the sliding block and the sliding groove 10, and a pressure roller 9 is fixedly connected between the front and rear sliding blocks. The compression spring is used to push the sliding block downward, and the sliding block then drives the pressure roller 9 to move downward, so that the pressure roller 9 is tightly pressed against the conveyor belt. When the conveyor belt is loose, it can be automatically tightened in time to avoid lateral deviation of the conveyor belt due to relaxation.

[0032] See also Figure 3 and Figure 4 In this embodiment, the anti-bias mechanism 5 includes a base 51 which is fixedly connected to the upper end surface of the roller frame 3 through a support and has an opening at the top. A toothed disc 52 is rotatably connected to the bottom of the base 51 through a rotating shaft. A torsion spring for resetting is fixedly connected between the toothed disc 52 and the inner cavity of the base 51. Two turntables 53 are fixedly connected to the bottom of the base 51 symmetrically through a rotating column, and the two turntables 53 are respectively distributed on the left and right sides of the toothed disc 52. The outer walls of the two turntables 53 are fixedly connected with arc-shaped racks 54 meshing with the toothed discs 52. An L-shaped connecting rod 55 is fixedly connected to the outer wall of the turntable 53 on the side away from the toothed disc 52. A shift plate 56 is fixedly connected to the short end of the L-shaped connecting rod 55. The radius of the arc-shaped rack 54 on the left of the anti-bias mechanism 5 is smaller than the radius of the arc-shaped rack 54 on the right, and the radius of the turntable 53 on the left is smaller than the radius of the turntable 53 on the right.

[0033] In the initial state, the long sections of the two L-shaped connecting rods 55 in the anti-deviation mechanism 5 are in the same straight line position, and the direction of the conveyor belt during operation is counterclockwise rotation. When the conveyor belt deviates during the operation of the conveying equipment, the conveyor belt moves in the deviation direction and will collide with the paddle 56 in the anti-deviation mechanism 5. Since the radius of the arc-shaped rack 54 on the right is greater than the radius of the arc-shaped rack 54 on the left, the movement stroke of the left paddle 56 is indirectly greater than the movement stroke of the right paddle 56. Specifically, when the conveyor belt touches the right paddle 56 in the anti-deviation mechanism 5, the right paddle 56 drives the right turntable 53 to rotate through the L-shaped connecting rod 55, and the right turntable 53 then drives the toothed disc 52 to rotate through the right arc-shaped rack 54, and the toothed disc 52 then drives the left arc-shaped rack 54 to rotate. The left turntable 53 is driven to rotate, and then the left turntable 53 is driven to rotate. Since the radii of the left and right arc-shaped racks 54 are different, the rotation stroke of the right arc-shaped rack 54 will be amplified, so that the rotation stroke of the left L-shaped connecting rod 55 is greater than the rotation stroke of the right L-shaped connecting rod 55. The left L-shaped connecting rod 55 then drives the paddle 56 to touch the edge of the conveyor belt, and applies pressure to the edge of the conveyor belt to move the edge of the conveyor belt toward the middle thereof, that is, a thrust is applied to the edge of the adjacent area of ​​the offset part of the conveyor belt toward the middle of the conveyor belt, so that the offset part of the conveyor belt can be pushed back to the normal position in time; finally, the torsion spring drives the toothed disc 52 to reverse and reset, and the toothed disc 52 then drives the two L-shaped connecting rods 55 to reset and rotate through the arc-shaped rack 54 and the turntable 53 until the two L-shaped connecting rods 55 move to the initial position.

[0035] See also Figure 3 and Figure 5 The pulling assembly 63 includes a rotating shaft 631, a reel 1 632, a reel 2 633, a cable 634 and a traction cable 635. The support plate 61 is symmetrically connected to the two rotating shafts 631 on one side of the anti-deviation mechanism 5 located on the left side. The outside of the rotating shaft 631 is fixedly connected with the reel 1 632 and the reel 2 633 from left to right in sequence. The outside of the reel 1 632 is wrapped with a cable 634. The end of the cable 634 away from the reel 1 632 is fixedly connected to the L-shaped connecting rod 55 located on the right side of the anti-deviation mechanism 5. The outside of the reel 2 633 is wrapped with a traction cable 635. The end of the traction cable 635 away from the reel 2 633 is fixedly connected to the left side of the U-shaped frame 62 through a connecting block. The radius of the reel 1 632 is smaller than the radius of the reel 2 633. The left end face of the support plate 61 is fixedly connected to the limiting ring through a connecting column, and the cable 634 passes through the limiting ring.

[0036] See also Figure 6 and Figure 7 The pulling assembly 66 includes a U-shaped groove 661 opened in the U-shaped frame 62 and connected with the two sliding grooves 64, a strip-shaped through groove connected with the U-shaped groove 661 is opened on the transverse section of the U-shaped frame 62, a transmission shaft that passes through the strip-shaped through groove is rotatably connected to the transverse section of the U-shaped frame 62, a reel 662 is fixedly connected to the outside of the transmission shaft and located in the strip-shaped through groove, a pull rope 663 is fixedly connected to the lower end surface of the interference rod 65, and one end of the pull rope 663 away from the interference rod 65 passes through the sliding groove 64 and the U-shaped groove 661 in turn and is fixedly connected to the outside of the reel 662, a spur rack 664 is fixedly connected to the upper end surface of the support plate 61, and a gear 665 meshing with the spur rack 664 is fixedly connected to the right part of the outer wall of the transmission shaft.

[0037] The L-shaped connecting rod 55 on the right part of the anti-deviation mechanism 5 is pressed by the offset part of the conveyor belt and moves, and at the same time, it also drives the cable 634 to move. The cable 634 then pulls the reel 1 632 to rotate. The reel 1 632 then drives the reel 2 633 to rotate through the rotating shaft 631. The reel 2 633 then winds up the traction cable 635, and the traction cable 635 then pulls the U-shaped frame 62 to move. Because the radius of the reel 1 632 is smaller than the radius of the reel 2 633, when the reel 1 632 is pulled to drive the reel 2 633 to rotate the same number of circles, the length of the traction cable 635 that is retracted by the reel 2 633 is greater than the length of the cable 634 that is released, thereby amplifying the movement stroke of the L-shaped connecting rod 55; The movement of the frame 62 drives the gear 665 to move synchronously. The gear 665 moves horizontally on the spur rack 664 and then rotates. The gear 665 then drives the reel 662 to rotate through the transmission shaft. The reel 662 then winds up the pull rope 663, and the pull rope 663 pulls the contact rod 65 downward. The contact rod 65 moves horizontally downward along the sliding groove 64. After moving down to a certain distance, the contact rod 65 will touch the edge of the conveyor belt where the conveyor belt is offset. Then the reel 662 continues to rotate, driving the contact rod 65 to continue to move downward. The contact rod 65 then pushes the offset edge of the conveyor belt downward from the top until the corresponding front and rear edges are flush with each other, so that the offset part of the conveyor belt can be pushed from the top.

[0038] After the conveyor belt deviation is corrected, the L-shaped connecting rod 55 is reversed and reset, thereby making the cable 634 become relaxed, and then the limit spring 7 is reset to drive the U-shaped frame 62 to move and reset to the initial position, and the U-shaped frame 62 then drives the traction cable 635 to move, and the traction cable 635 then pulls the reel 2 633 to reverse, and the reel 2 633 then drives the reel 1 632 to reverse through the rotating shaft 631, and finally the reel 1 632 winds up the cable 634 to complete the reset.

[0039] During operation, the sliding block is pushed downward by the compression spring during the operation of the conveyor belt, and the sliding block then drives the pressure roller 9 to move downward and touch the conveyor belt to ensure that the conveyor belt is always in a taut state. When the conveyor belt deviates during operation, the anti-deviation mechanism 5 will be triggered to operate, and the anti-deviation mechanism 5 will touch the conveyor belt from the side to push it to a normal position. The operation of the anti-deviation mechanism 5 also drives the deviation correction mechanism 6 to operate, and the deviation correction mechanism 6 pushes the deviated part of the conveyor belt from above until the deviated area of ​​the conveyor belt returns to its normal position, that is, the corresponding front and rear edges of the conveyor belt are in a flush position, and the anti-deviation mechanism 5 and the deviation correction mechanism 6 are linked to each other to prevent the conveyor belt from deviating in multiple directions.
