[0022] The present invention provides the following embodiments.
[0023] Embodiment 1
[0024] As Figure 1 、 Figure 2 shown, an adjustable belt anti-deviation vertical roll device of the present invention includes a vertical roll 1, a vertical roll frame 2, a vertical support rod 3, an adjusting screw 4 and a channel-shaped connecting piece 5. The vertical roll 1 is rotatably installed in the vertical roll frame 2. The two sides of the channel-shaped connecting piece 5 are fixed in the middle of the vertical roll frame 2, forming an activity space 6 with the vertical roll frame 2. A long slot 7 is opened on the channel-shaped connecting piece 5 along the length direction of the vertical roll frame 2. The bottom of the vertical roll frame 2 is hinged to the middle of the vertical support rod 3. Through holes are opened at the top of the vertical support rod 3, and a guiding nut 8 is fixed at each end of the through hole. The adjusting screw 4 is threadedly sleeved in the two guiding nuts 8. One end of the adjusting screw 4 is inserted into the long slot 7 on the channel-shaped connecting piece 5 and then fixed to the sliding head 9, and the other end is connected to the handle 10.
[0025] A reverse L-shaped clip 11 is fixed to the bottom of the vertical support rod 3. The clip 11 and the vertical support rod 3 are clamped on both sides of the belt conveyor support, and are fixed to the belt conveyor support by bolts and nuts. The detachable design of the bolt and nut connection here is more flexible than directly welding the vertical support rod 3 to the belt support, and the design of the clip 11 makes the connection firm.
[0026] The part of the upper part of the vertical support rod 3 where the guiding nut 8 is fixed is bent towards the vertical roller frame 2, and the bending angle is 25-30 degrees. After bending, the angle between the adjusting screw rod 4 and the vertical roller frame 2 is closer to perpendicular, the force is better, and the structure is more reasonable.
[0027] The handle 10 is a ring without sharp corners, which is convenient for operation and safe.
[0028] The sliding head 9 is hemispherical, and its diameter is greater than the width of the long hole 7. The adjusting screw rod 4 is connected to the plane of the sliding head 9.
[0029] As Figure 4 shown, the usage method of this embodiment is as follows:
[0030] Install the present utility model symmetrically on the belt conveyor supports on both sides, clamp the belt conveyor supports between the vertical support rod 3 and the clip 11, and fix them with bolts and nuts. Then rotate the handle 10 to drive the rotation of the adjusting screw rod 4, adjust the screw rod length between the vertical support rod 3 and the vertical roller frame 2, so that the vertical roller frame 2 drives the vertical roller 1 to rotate around the bottom hinge point, adjust the angle of the vertical roller 1, and make the vertical roller 1 effectively contact the belt 17 to prevent the belt 17 from running off track.
[0031] During the above adjustment process, when the adjusting screw rod 4 rotates, there will be a position change between its end and the vertical roller frame 2. The long hole 7 on the channel-shaped connecting piece 5 meets the requirements of this position change, so that the adjusting screw rod 4 can drive the sliding head 9 to slide up and down in the moving space 6.
[0032] Embodiment 2
[0033] As Figure 3 shown, an adjustable belt anti-running-off-track vertical roller device of the present utility model includes a vertical roller 1, a vertical roller frame 2, a vertical support rod 3, an adjusting screw rod 4 and a channel-shaped connecting piece 5. The vertical roller 1 is rotatably installed in the vertical roller frame 2. Two sides of the channel-shaped connecting piece 5 are fixed in the middle of the vertical roller frame 2, forming a moving space 6 between the channel-shaped connecting piece 5 and the vertical roller frame 2. A long hole 7 is opened along the length direction of the vertical roller frame 2 on the channel-shaped connecting piece 5. The bottom of the vertical roller frame 2 is hinged in the middle of the vertical support rod 3. Through holes are opened at the top of the vertical support rod 3, and a guiding nut 8 is fixed at each end of the through hole. The adjusting screw rod 4 is sleeved in the two guiding nuts 8 through threads. One end of the adjusting screw rod 4 is inserted into the long hole 7 on the channel-shaped connecting piece 5 and then fixed to the sliding head 9, and the other end is connected to the handle 10.
[0034] A horizontal adjusting device 12 is fixed to the bottom end of the vertical support rod 3. The horizontal adjusting device 12 includes a horizontal adjusting rod 13, a vertical movable rod 14, and a set bolt 15. A plurality of adjusting holes 16 are equidistantly formed in the horizontal adjusting rod 13. One end of the horizontal adjusting rod 13 is fixed to the bottom end of the vertical support rod 3, and the other end is slidably sleeved in the sliding through hole in the upper part of the vertical movable rod 14. A set hole corresponding to the adjusting hole 16 is also provided on the vertical movable rod 14. The set bolt 15 passes through the set hole and the adjusting hole 16, and cooperates with a nut to fix the horizontal adjusting rod 13 and the vertical movable rod 14 together.
[0035] A reverse L-shaped clip 11 is fixed to the bottom of the vertical movable rod 14. The clip 11 and the vertical support rod 3 are clamped on both sides of the belt conveyor support, and are fixed to the belt conveyor support through bolts and nuts.
[0036] The part of the upper part of the vertical support rod 3 where the guiding nut 8 is fixed is bent towards the vertical roller frame 2, and the bending angle is 25 - 30 degrees.
[0037] The handle 10 is a ring.
[0038] The sliding head 9 is hemispherical, its diameter is larger than the width of the long hole 7, and the adjusting screw rod 4 is connected to the plane of the sliding head 9.
[0039] In the second embodiment, the horizontal adjusting device 12 is added compared with the first embodiment, so that the adjustable distance of the utility model in the horizontal direction becomes longer and the adaptable range increases.
[0040] As mentioned above, the above are only the preferred specific embodiments of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the utility model should be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
