Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyors, and specifically, to a reversible belt conveyor bracket group and a reversible belt conveyor. Background Art

[0002] As a main conveying device, the reversible belt conveyor plays a very crucial role in production due to the needs of the production process. However, during the installation and use process, belt deviation is a common problem, especially during the commissioning and operation of the reversible belt, which is the most difficult to adjust. Since the reversible belt rotates in both forward and reverse directions, it often deviates during reverse rotation, resulting in contradictions during adjustment. Summary of the Invention

[0003] The present invention is made to solve the above technical problems. One of its purposes is to provide a reversible belt conveyor bracket group that can support the stable operation of the reversible belt and make it less likely to have an eccentric phenomenon when the reversible belt runs forward or backward.

[0004] Another purpose of the present invention is to provide a reversible belt conveyor that adopts the above reversible belt conveyor bracket group, and the reversible belt in it is less likely to have an eccentric phenomenon when running forward or backward.

[0005] According to an embodiment of the present invention, a reversible belt conveyor bracket group is provided, including a fixed frame and a plurality of roller bracket groups thereon. The roller bracket group includes: a bottom frame provided on the fixed frame; two first support columns provided in the middle of the bottom frame; two second support columns respectively provided at both ends of the bottom frame, with a height higher than that of the first support columns; a first roller rotatably provided on the two first support columns; two second rollers, one end rotatably provided on the first support columns and the other end rotatably provided on the second support columns; wherein a limiting groove for accommodating the rotating shaft of the second roller is formed at the upper end of the second support column, and the width of the limiting groove along the running direction of the reversible belt is greater than the width of the rotating shaft.

[0006] As an embodiment, the roller bracket group further includes: an adjustment plate, the lower end of which is rotatably connected to the upper end of the second support column, and an installation groove sleeved on the rotating shaft is formed at the upper end, and the height of the installation groove is higher than that of the limiting groove.

[0007] As an embodiment, the adjustment plate is a plate body with a width greater at the upper end than at the lower end.

[0008] As an embodiment, the adjustment plate is a triangular plate body.

[0009] As an embodiment, the ratio of the width of the limiting groove along the running direction of the reversible belt to the height from the limiting groove to the lower end of the second support column is 0.07 - 0.1.

[0010] As an embodiment, at least one of the idler bracket groups is a self-aligning idler bracket group, and a self-aligning shim is arranged between the chassis of the self-aligning idler bracket group and the fixed bracket.

[0011] As an embodiment, the thickness of the self-aligning shim is 15 mm - 20 mm.

[0012] According to an embodiment of the present invention, there is provided a reversible belt conveyor, including: the reversible belt conveyor bracket group as described above; a reversible belt arranged on the first idler and the second idler; and a driving device linked to the reversible belt for driving the reversible belt to run forward or backward.

[0013] According to the above description and practice, in the reversible belt conveyor bracket group of the present invention, limiting grooves are provided on the second support columns on both sides, and the rotation shafts of the idlers on both sides are movably arranged in the limiting grooves. When the idlers support the reversible belt, under the action of the reversible belt, the outer ends of the rotation shafts will abut against one side wall of the limiting groove. As the running direction of the reversible belt changes, the rotation shafts will respectively abut against different side walls of the limiting groove, playing a role in aligning the reversible belt, and then preventing the reversible belt from being eccentric during operation.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] According to an embodiment of the present invention, a reversible belt conveyor bracket group is provided. Please refer to Figures 1 to 6, the reversible belt conveyor bracket group includes a fixed frame 1 and several roller bracket groups thereon. The fixed frame 1 is arranged along the extending direction of the reversible belt conveyor, and several roller bracket groups are arranged above the fixed frame 1 for supporting the reversible belt.

[0026] Please combine Figure 3 and Figure 4 , each roller bracket group includes a bottom frame 2, a first support column 3, a second support column 4, a first roller 5 and a second roller 6. Among them, the bottom frame 2 is arranged on the fixed frame 1, such as bolted or clamped on the fixed frame 1, and its main function is to fix the first support column 3 and the second support column 4. Two first support columns 3 are fixedly arranged in the middle of the bottom frame 2, and the first roller 5 is rotatably arranged on the two first support columns 3 for horizontally supporting the reversible belt. Two second support columns 4 are respectively fixedly arranged at the two ends of the bottom frame 2, the height of the second support column 4 is higher than that of the first support column 3, one end of the two second rollers 6 is rotatably arranged on the first support column 3, and the other end of the two second rollers 6 is rotatably arranged on the second support column 4. The two second rollers 6 form a relatively inclined structure, and when cooperating with the first roller 5 to support the reversible belt, it can make the reversible belt form a form with a downward depression in the middle to prevent the materials on the reversible belt from falling from the side.

[0027] In this embodiment, a limiting groove 8 for accommodating the rotating shaft 7 of the second roller 6 is formed at the upper end of the second support column 4, and the width of the limiting groove 8 along the running direction of the reversible belt is greater than the width of the rotating shaft 7.

[0028] When the reversible belt conveyor bracket group is actually applied, the second roller 6 supports the reversible belt. If the reversible belt runs in the first direction, the second roller 6 will move in the first direction under the action of the reversible belt until the outer end of the rotating shaft 7 of the second roller 6 abuts against one side wall of the limiting groove 8; if the reversible belt runs in the second direction, the second roller 6 will move in the second direction under the action of the reversible belt until the outer end of the rotating shaft 7 of the second roller 6 abuts against the other side wall of the limiting groove 8. Compared with the fixed position of the second roller 6, in this structure form of the reversible belt conveyor bracket group, as the running direction of the reversible belt changes, the rotating shaft 7 of the second roller 6 will respectively abut against different side walls of the limiting groove 8, playing a role in centering the reversible belt, and then preventing the reversible belt from being eccentric during operation.

[0029] Furthermore, in this embodiment, each roller bracket group further includes two adjusting plates 9. As Figures 4 to 6 shown, the lower end of the adjusting plate 9 is rotatably connected to the upper end of the second support column 4, and an installation groove 10 sleeved on the rotating shaft 7 is formed at the upper end, and the height of the installation groove 10 is higher than that of the limiting groove 8.

[0030] During actual use, if the reversible belt runs to the left in the figure, it will push the upper end of the second idler 6 to move to the left, and the rotating shaft 7 thereon will rotate to the left around the rotation center of the adjusting plate 9 until it abuts against the left side wall of the limit groove 8, that is Figure 5 the state shown. If the reversible belt then runs to the right in the figure, it will push the upper end of the second idler 6 to move to the right, and the rotating shaft 7 thereon will rotate to the right around the rotation center of the adjusting plate 9 until it abuts against the right side wall of the limit groove 8, that is Figure 6 the state shown. Compared with the rotating shaft 7 of the second idler 6 being fixed on the center line of the second support column 4, this kind of movably arranged rotating shaft 7 can play a centering role for the reversible belt during actual operation, ensuring that the reversible belt does not show an eccentric phenomenon during operation. And after setting the adjusting plate 9, the rotating shaft 7 on the second idler 6 moves more stably and smoothly with the reversible belt, enabling the above-mentioned centering function to be maintained continuously and stably.

[0031] Further, the adjusting plate 9 is a plate body with a width at the upper end greater than that at the lower end, and it is more likely to rotate as the reversible belt rotates. For example, in this embodiment, the adjusting plate 9 has a triangular structure, as Figures 4 to 6 shown. During actual operation, the adjusting plate 9 can rotate around its own rotation center as the reversible belt runs forward or backward to ensure the realization of the above-mentioned centering function.

[0032] As an implementation manner, the ratio of the width of the limit groove 8 along the belt running direction to the height from the limit groove 8 to the lower end of the second support column 4 is 0.07 - 0.1. Within this width range, the rotating shaft 7 of the second idler 6 can only move a preset distance in the limit groove 8, and while realizing the above-mentioned centering function, it can also ensure the normal operation of the reversible belt and other idler structures.

[0033] As an implementation manner, in this reversible belt conveyor bracket group, at least one idler bracket group is a centering idler bracket group, and a centering gasket 11 is provided between the chassis 2 and the fixed bracket 1 in this centering idler bracket group. For example, in Figure 2 the middle idler bracket group is set as a centering idler bracket group, and a centering gasket 11 is provided between the chassis 2 and the fixed bracket 1 therein. Compared with other idler bracket groups, its height is increased, which can further improve the stability of the reversible belt during operation and prevent the reversible belt from showing an eccentric phenomenon.

[0034] Further, in this embodiment, the thickness of the centering gasket 11 is 15 mm - 20 mm. Within this thickness range, this centering idler bracket group can realize the above-mentioned centering function while ensuring the normal operation of the reversible belt and other idler bracket groups.

[0035] In this embodiment, a reversible belt conveyor is also disclosed, which applies the above-mentioned reversible belt conveyor bracket group, and further includes a reversible belt and a driving device. The reversible belt is arranged on the first roller 5 and the second roller 6 in the above-mentioned reversible belt conveyor bracket group, and the driving device is linked with the reversible belt to drive the reversible belt to run forward or backward on the first roller 5 and the second roller 6.

[0036] When the reversible belt conveyor is in use, the reversible belt therein can always run stably, and there will be no eccentric phenomenon during forward or backward running.

[0037] Furthermore, in this embodiment, the material dropping place in the reversible belt conveyor is a traditional shock-absorbing roller rack group, the parts close to the head roller and the tail roller are traditional fixed roller rack groups, and multiple above-mentioned reversible belt conveyor bracket groups are arranged at other parts. This can ensure the long-term stable operation of the reversible belt conveyor without the eccentric phenomenon of the reversible belt.

[0038] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
