Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and particularly relates to a device for correcting belt deviation of a high-strength belt conveyor. Background Art

[0002] A belt conveyor is a transmission device used to transport materials. Its main structure includes a frame, a roller unit installed on the frame, a belt supported on the roller, and a belt roller that drives the belt transmission. The material is transported through the transmission belt, such as long-distance transmission.

[0003] High-strength belt conveyors are different from traditional ordinary belt conveyors. They have a large load and transmission material volume, such as the belt conveyors used to transmit mineral materials in mining, and the transmission distance is long. They are mostly used in the mining industry. During the working process, high-strength belt conveyors not only have a large load volume and a long transmission distance, but also have a relatively fast transmission speed. Therefore, in the actual working process, it is very important to maintain the smooth transmission of high-strength belt conveyors.

[0004] However, in actual use, as the belt conveyor ages, the belt is prone to deviation during the transmission process. For example, the belt is loose, the frame is loose, and the rollers are loose, which causes the belt to deviate during transmission. The deviated belt is very likely to cause a large amount of material to fall off the belt and easily cause the belt to be damaged. Therefore, in actual use, once the deviation occurs, it needs to be corrected immediately. However, due to the heavy weight of the belt itself during the belt transmission, especially when the material is loaded, it is difficult to correct the deviation.

[0005] In addition, since the direction of the belt deviation is mostly irregular during the belt transmission process, it is difficult to correct the belt once it deviates in a certain direction of the frame during operation. Therefore, in the actual working process, it is obviously impossible to effectively and accurately correct the position of the belt by correcting the belt, especially the belt with materials on it. Once the correction is not timely, the high-speed running belt will produce chain deviation, resulting in a large-scale deviation, which further increases the difficulty of correction.

During operation, if the belt is displaced to the left, the cylinder on the left is opened, and the cylinder drives the top wheel upward to contact the left side of the V-shaped roller bracket. At this time, the left side of the V-shaped roller bracket tilts upward (with the articulated ball as the fulcrum). At this time, the raised left roller supports the belt again. Conversely, the right side is raised. In this way, the angle can be adjusted by raising the two sides of the V-shaped roller bracket, which is convenient for accommodating the displaced belt on both sides.

[0041] Example 1

[0042] like Figure 1-5As shown, a high-strength belt conveyor belt deviation correction device includes a belt deviation correction mechanism, which includes a roller assembly for supporting the belt, and the roller assembly includes a V-shaped roller bracket 11, the V-shaped roller bracket 11 is horizontal in the middle, and the two sides are tilted upward. Like the existing rollers, the V-shaped roller bracket 11 is equipped with three rollers 12 that are excluded in a V shape; the rollers are rotatably connected to the V-shaped roller bracket 11 (the two ends of the roller 12 rotate on the fixed ends on the V-shaped roller bracket 11).

[0043] The belt deviation correction mechanism further comprises a first adjustment component for adjusting the angles of both sides of the V-shaped roller bracket 11 up and down, and a second adjustment component for rotationally adjusting the angle of the V-shaped roller bracket 11 .

[0044] Specifically, in the actual working process, the left and right ends of the V-shaped roller support 11 are adjusted by the first adjustment component, such as raising the left end of the V-shaped roller support 11 and lowering the right end, and vice versa. The rotation adjustment is achieved by the second adjustment component. The above method can be used to adjust the V-shaped roller support 11-roller structure in two different ways, and the position of the offset belt can be adjusted by fully changing the V-shaped roller support 11-roller posture, so as to facilitate the offset belt to be fully supported on the roller again, and avoid the material tipping over due to the offset.

[0045] Specifically, the first adjustment assembly includes a base plate 2, and the top center position of the base plate 2 is hinged to the V-shaped roller bracket 11 through a hinge.

[0046] Specifically, the articulated part includes an articulated seat 241 fixedly connected to the base plate 2, and the articulated seat 241 is articulated with an articulated ball seat 24 (the articulation method of the articulated ball seat 24 on the articulated seat 241 is the existing conventional method, specifically, an articulated limit groove is opened on the articulated seat 241, and the articulated ball is articulated and limited in the groove), and a mounting rod is welded to the top of the articulated ball seat 24, and the mounting rod is welded to the bottom of the V-shaped roller bracket 11.

[0047] At the same time, the first adjustment component also includes a top wheel structure supported on both sides of the bottom of the V-shaped roller bracket 11, and the top wheel structure includes a cylinder 21, and the piston rod of the cylinder 21 is assembled and connected to the top wheel 22 that abuts against the bottom of the V-shaped roller bracket 11 (specifically, the piston rod of the cylinder 21 is installed at the bottom of the wheel frame on the roller).

[0048] During operation, if the belt deviates to the left, the cylinder 21 on the left is opened, and the cylinder 21 drives the top wheel 22 upward to contact the left side of the V-shaped roller bracket 11. At this time, the left side of the V-shaped roller bracket 11 is tilted upward (with the articulated ball as the fulcrum), and the raised left roller supports the belt again. Conversely, the right side is raised.

[0049] In order to improve the rolling stability of the top wheel 22 , track grooves A adapted to the top wheel 22 are respectively opened on the left and right sides of the V-shaped roller bracket 11 ; the top wheel 22 rolls in the track grooves A.

[0050] At the same time, in order to change the height of the top wheel 22 driven by the cylinder 21, the bottom of the above-mentioned cylinder 21 is rotatably connected with a height-adjusting screw 211 (specifically: the top position of the height-adjusting screw 211 is a smooth part, a fixed boss is installed at the bottom of the cylinder barrel of the cylinder 21, and the top of the height-adjusting screw 211 is rotatably connected in the fixed boss), and the height-adjusting screw 211 is threadedly connected to the base plate 2.

[0051] By turning the height adjustment screw 211 and adjusting the height of the height adjustment screw drive cylinder 21, it is convenient to change the lifting height of the top wheel 22, and then adjust the flip angle of the V-shaped roller bracket 11 (under normal circumstances, the top wheel 22 and the V-shaped roller bracket 11 maintain a certain distance).

[0052] Example 2

[0053] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, a plurality of reset springs 23 are fixedly connected to both ends of the V-shaped roller bracket 11. The reset springs 23 are used to close the cylinder 21 when the V-shaped roller bracket 11 needs to be reset (for example, when the belt is deviated and the normal track is restored, the V-shaped roller bracket 11 needs to be reset to the initial state), and the reset springs 23 are used to cooperate to achieve rapid reset.

[0054] During operation, after adjustment, the V-shaped roller bracket 11 needs to be in a positioned state. Therefore, in order to lock the hinge and prevent the V-shaped roller bracket 11 from being unstable and shaking, the hinge is positioned by a locking structure.

[0055] Specifically, the locking structure includes a locking cylinder 25, a piston rod of which is fixedly connected to a locking rod 251, and the locking rod 251 passes through the hinge seat 241. After the angle is adjusted, the locking rod 251 is pressed and locked on the hinge ball seat 24 (an adaptive through hole is provided on the hinge seat 241, and after the locking rod 251 enters the through hole, it is locked and squeezed onto the hinge ball seat 24 to achieve positioning, and when the angle is adjusted, it remains out of the squeezed state).

[0056] In the above-mentioned manner, during the working process, the V-shaped roller bracket 11-roller positioning is controlled according to whether the angle is adjusted or not.

[0057] At the same time, a cylinder seat for installing the cylinder barrel of the locking cylinder 25 is welded on the chassis plate 2.

[0058] Example 3

[0059] like Figure 1-5 As shown, based on the structure of Example 2, in actual working process, according to the range of belt deviation, the second adjustment component cooperates with the first adjustment component to support the deviated belt, especially the seriously deviated belt.

[0060] Specifically, the second adjustment component includes a rail base 31 (the shape of the rail base 31 is circular, with mounting arms welded on both sides, and the mounting arms 311 are installed on the frame in the existing manner), and the bottom of the base plate 2 is assembled and connected with two rollers 32 arranged in a left-right symmetrical distribution. The rollers 32 roll on the rail base 31 (during the adjustment process, the rotation stability achieved in this way is high, and the accuracy of the adjustment angle is high). At the same time, the second adjustment component also includes a drive motor 33 assembled and connected to the bottom position of the rail base 31, and the output shaft of the drive motor 33 is fixedly assembled at the bottom center position of the base plate 2. According to the existing method, the output shaft of the drive motor 33 is rotatably connected to the center position of the rail base 31.

[0061] During operation, the drive motor 33 works to drive the chassis plate 2 carrying the V-shaped roller bracket 11-roller structure to rotate within a certain angle, and the V-shaped roller bracket 11-roller is adjusted to the supporting position in time according to the belt deviation direction through rotation, so as to fully support the belt.

[0062] Example 4

[0063] like Figure 1-5 As shown, based on the structure of Example 1, the left and right ends of the V-shaped roller bracket 11 are respectively equipped with offset contact roller mechanisms; the offset contact roller mechanism includes a roller base frame 131 welded to the side walls on both sides of the V-shaped roller bracket 11, and the roller base frame 131 is rotatably connected to a plurality of vertically arranged contact rollers 13 (same as the existing method, the bottom of the contact roller 13 is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the roller base frame 131).

[0064] The function of the resistance roller 13 is to block the belt to prevent the offset belt from being too seriously offset. When the offset belt tends to be excessively offset to the left or right sides, the edge of the belt contacts the resistance roller 13, and the resistance roller 13 rotates and blocks the belt at the same time.

[0065] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
