[0031] As Figures 1 to 3As shown, the utility model discloses an adjustable upper deflection adjusting roller support for a belt conveyor, comprising a frame 1, a deflection adjusting roller frame 2, a rotating component and an adjusting device. The deflection adjusting roller frame 2 is located at the top of the frame 1. The frame 1 and the deflection adjusting roller frame 2 are rotatably connected through the rotating component to facilitate the deflection adjusting roller frame 2 to rotate in the horizontal direction. The adjusting device is installed between the frame 1 and the deflection adjusting roller frame 2 to adjust the rotation angle of the deflection adjusting roller frame 2. The adjusting device is located on one side of the rotating component. The adjusting device comprises an adjusting mechanism and a limiting mechanism. The limiting mechanism is connected to the adjusting structure to limit the rotation of the adjusting mechanism. The adjusting mechanism comprises a sawtooth disk 3 and a clamping block. 4. Fixed rod 5, rotating rod 6 and connecting plate 7. The sawtooth disk 3 is installed on the top of the frame 1. The spacing between two adjacent tooth structures of the sawtooth disk 3 matches the thickness of the block 4 so that the block 4 is clamped in the tooth structure of the sawtooth disk 3. The ends of the rotating rod 6 along the length direction pass through the connecting plate 7 and the block 4 respectively and are connected with the fixed rod 5. The fixed rod 5 is horizontally arranged and perpendicular to the rotating rod 6. The block 4 is fixedly connected to the rotating rod 6. The top of the connecting plate 7 is fixedly connected to the bottom of the deviation adjustment roller frame 2. The end of the connecting plate 7 away from the deviation adjustment roller frame 2 is provided with a first through hole 16. The rotating rod 6 passes through the first through hole 16 and is rotatably connected to the connecting plate 7.

[0032] The adjusting roller frame 2 is rotatably mounted on the frame 1 through a rotating component. The adjusting roller frame 2 can make a circular motion in the horizontal direction. The serrated disc 3 is mounted on one side of the rotating component. The toothed structure of the serrated disc 3 is away from the rotating component. The limiting mechanism is connected to the end of the rotating rod 6 away from the clamping block 4. When the clamping block 4 is engaged in the tooth groove of the serrated disc 3, the angle of the adjusting roller frame 2 is fixed. When the clamping block 4 is disengaged from the tooth groove of the serrated disc 3, the adjusting roller frame 2 can be rotated arbitrarily in the horizontal direction. When the adjusting roller frame 2 rotates to the target angle, the rotating rod 6 moves left or right along the first through hole 16, driving the clamping block 4, the connecting plate 7 and the fixing rod 5 to move left or right. When the adjusting roller frame 2 rotates to the target angle, the rotating rod 6 moves left or right along the first through hole 16, driving the clamping block 4, the connecting plate 7 and the fixing rod 5 to move left or right. After the angle is marked, the rotation of the rotating rod 6 is limited by the limiting mechanism, and then the fixed rod 5 drives the block 4 to engage in the corresponding tooth groove of the sawtooth disk 3, so that the positions of the connecting plate 7 and the block 4 are fixed. Or after the deviation adjustment roller frame 2 is rotated to the target angle, the block 4 is first engaged in the corresponding tooth groove of the sawtooth disk 3 by the fixed rod 5, and then the rotation of the rotating rod 6 is limited by the limiting mechanism, so that the positions of the connecting plate 7 and the block 4 are fixed, and the position of the deviation adjustment roller frame 2 is fixed at the same time, and the angle adjustment of the deviation adjustment roller frame 2 is completed, which effectively solves the problem of the deviation adjustment roller bracket swinging back and forth when the belt conveyor is running, and the block 4 moves along the tooth groove of the sawtooth disk 3 to more accurately adjust the deviation of the belt conveyor and ensure safe operation of the belt conveyor.

[0033] like Figures 2 to 4As shown in the figure, the limiting mechanism includes a ratchet wheel 8, a pawl 9, a connecting rod 10 and a spring 11. The ratchet wheel 8 is fixedly connected to the end of the rotating rod 6 away from the clamping block 4. The pawl 9 meshes with the ratchet wheel 8. The inner side of the pawl 9 is fixedly connected to the end of the connecting rod 10 along the length direction. The end of the connecting rod 10 away from the pawl 9 is slidably connected to the connecting plate 7. The spring 11 is sleeved on the connecting rod 10. The two ends of the spring 11 along the length direction are respectively fixedly connected to the inner side wall of the pawl 9 and the outer side wall of the connecting plate 7.

[0034] In this embodiment, the spring 11 is a compression spring. The middle of the ratchet wheel 8 is fixedly connected to the end of the rotating rod 6. The connecting rod 10 is a cylindrical rod. The connecting rod 10 passes through the connecting plate 7 and is slidably connected to the connecting plate 7. The spring 11 is sleeved on the part of the connecting rod 10 between the pawl 9 and the connecting plate 7. When the pawl 9 is pressed, the spring 11 is compressed, and the connecting rod 10 slides inwardly towards the connecting plate 7, and the pawl 9 disengages from the ratchet wheel 8. Rotate the fixing rod 5, and the fixing rod 5 drives the clamping block 4, the rotating rod 6 and the ratchet wheel 8 to rotate upward synchronously, so that the clamping block 4 disengages from the current tooth groove of the sawtooth disc 3. Then rotate the deviation adjusting idler bracket 2, and the deviation adjusting idler bracket 2 drives the connecting plate 7, the rotating rod 6, the clamping block 4 and the fixing rod 5 to rotate synchronously. When the deviation adjusting idler bracket 2 rotates left or right, the rotating rod 6 moves left or right synchronously along the first through hole 16, thereby driving the clamping block 4 and the fixing rod 5 to move. When the deviation adjusting idler bracket 2 rotates to the target angle, drive the clamping block 4 to rotate downward through the fixing rod 5 to engage the clamping block 4 into the tooth groove of the sawtooth disc 3. At this time, release the pressing of the pawl 9. Under the elastic force of the spring 11, the pawl 9 meshes with the ratchet wheel 8, the position of the clamping block 4 is fixed, and the angle adjustment of the deviation adjusting idler bracket 2 is completed. The position of the clamping block 4 is locked by the meshing of the pawl 9 and the ratchet wheel 8, and the position of the rotating rod 6 fixedly connected to the clamping block 4 is fixed. Since the two ends of the spring 11 along the length direction are respectively fixedly connected to the inner side of the pawl 9 and the outer side of the connecting plate 7, the position of the connecting plate 7 is fixed under the action of the spring 11. Since the top of the connecting plate 7 is fixedly connected to the bottom of the deviation adjusting idler bracket 2, the position of the deviation adjusting idler bracket 2 is fixed, effectively solving the problem that the upper deviation adjusting idler bracket swings back and forth during the operation of the belt conveyor.

[0035] Further, the connecting rod 10 passes through the second through hole on the connecting plate 7 and is slidably connected to the connecting plate 7. A limiting plate is provided at the end of the connecting rod 10 inside the connecting plate 7. When the spring 11 is in a free state, the limiting plate is in contact with the inner side wall of the connecting plate 7. When the spring 11 is in a compressed state, the limiting plate moves away from the connecting plate 7. The limiting plate can prevent the connecting rod 10 from disengaging from the second through hole. At the same time, the limiting plate can also push the connecting plate 7 towards the ratchet wheel 8 and the pawl 9, restricting the moving direction and moving distance of the connecting plate 7, and improving the stability of the position of the connecting plate 7.

[0036] As Figure 3As shown, the slewing member includes a horizontal plate 14 and a rotating column 13. The horizontal plate 14 is a square plate, and the horizontal plate 14 is fixedly connected to the bottom of the deviation adjusting idler bracket 2. The top of the rotating column 13 is fixedly connected to the side of the horizontal plate 14 away from the deviation adjusting idler bracket 2.

[0037] In this embodiment, the rotating column 13 is of a cylindrical structure. The rotating column 13 is rotatably connected to the frame 1 through a ball bearing 15. The ball bearing 15 cooperates with the rotating column 13 to enable the deviation adjusting idler bracket 2 to rotate in the horizontal direction.

[0038] As Figure 3 and Figure 5 shown, the deviation adjusting idler bracket 2 includes an idler bracket and an idler groove. The idler groove is snap-fitted on the idler bracket. The idler bracket includes a horizontal bracket 203 and an inclined bracket 204. Both the left and right ends of the horizontal bracket 203 are fixedly connected with the inclined bracket 204. The idler groove includes a first idler groove 201 and a second idler groove 202. The first idler groove 201 is spaced at both ends of the horizontal bracket 203, and the second idler groove 202 is provided at the end of the inclined bracket 204 away from the horizontal bracket 203.

[0039] In this embodiment, the cross-sections of the horizontal bracket 203 and the inclined bracket 204 are both of an inverted V-shaped structure. The lengths of the two inclined brackets 204 are the same, and the angles between the two inclined brackets 204 and the horizontal bracket 203 are the same. The two inclined brackets 204 are respectively fixedly connected to the left and right ends of the horizontal bracket 203 along the length direction to form an idler bracket. The bottoms of the first idler groove 201 and the second idler groove 202 are matched with the idler bracket and are both of an inverted V-shaped structure, which is convenient for snap-fitting the first idler groove 201 and the second idler groove 202 on the horizontal bracket 203 and the inclined bracket 204. The first idler groove 201 includes a first vertical portion, a second vertical portion and a connecting portion. The widths of the first vertical portion and the second vertical portion are the same and the first vertical portion is higher than the second vertical portion. The first vertical portion and the second vertical portion are spaced apart and the tops are connected by the connecting portion. The tops of the first vertical portion and the connecting portion are both provided with grooves for snap-fitting idlers. The two first idler grooves 201 are respectively arranged at both ends of the horizontal bracket 203 and the first vertical portions of the two first idler grooves 201 are close to each other. The second idler groove 202 includes a third vertical portion and an extension portion. The height of the extension portion is the same as the height of the third vertical portion. The number of the extension portions is two. The two extension portions are respectively vertically connected to the length direction of the third vertical portion along the length direction. The bottom of the third vertical portion is of an inverted V-shaped structure so that the third vertical portion can be snap-fitted on the inclined bracket 204. The top of the third vertical portion is provided with a groove for snap-fitting an idler.

[0040] As Figure 3 and Figure 5As shown, the frame 1 includes a horizontal portion 101 and a vertical portion 102. The vertical portion 102 is of a U-shaped structure. Both ends of the horizontal portion 101 in the length direction are connected with the vertical portion 102, and the outer side wall of the transverse end of the vertical portion 102 is connected with the end of the horizontal portion 101.

[0041] In this embodiment, a ball bearing 15 is provided on the horizontal portion 101. The horizontal portion 101 enables the deviation adjusting idler bracket 2 to be rotatably installed on the horizontal portion 101 through the ball bearing 15.

[0042] As Figure 3 shown, the serrated disc 3 is of a sector structure, and the center point of the serrated disc 3 is collinear with the central axis of the rotating column 13 at the bottom of the deviation adjusting idler bracket 2.

[0043] In this embodiment, according to the actual working conditions, the central angle of the serrated disc 3 is designed to be the required angle, and the center of the serrated disc 3 is collinear with the central axis of the rotating column 13.

[0044] As Figure 3 and Figure 5 shown, a handle 12 is provided at the end of the fixed rod 5 away from the clamping block 4, and the handle 12 is perpendicular to the fixed rod 5.

[0045] The fixed rod 5 can be driven to rotate up and down through the handle 12. When the fixed rod 5 rotates, the rotating rod 6 fixedly connected thereto rotates in the first through hole 16, and at the same time, the clamping block 4 rotates synchronously with the fixed rod 5.

[0046] During use, the fixed rod 5 is driven to rotate up and down through the handle 12. The fixed rod 5 drives the rotating rod 6 to rotate synchronously and drives the clamping block 4 to rotate along the rotation direction of the rotating rod 6. When the clamping block 4 is engaged in the tooth groove of the serrated disc 3, the angle of the deviation adjusting idler bracket 2 is fixed. When the clamping block 4 disengages from the tooth groove of the serrated disc 3, the deviation adjusting idler bracket 2 can rotate freely through the rotating column 13 at the bottom. By engaging the clamping block 4 in different tooth grooves of the serrated disc 3, the angle of the deviation adjusting idler bracket 2 is adjusted. When the pawl 9 is pushed towards the connecting plate 7 to make the connecting rod 10 slide towards the inside of the connecting plate 7, the spring 11 is compressed, and the pawl 9 disengages from the tooth groove of the ratchet wheel 8. The clamping block 4 is driven by the fixed rod 5 to disengage from the tooth groove of the serrated disc 3 to adjust the angle of the deviation adjusting idler bracket 2. At this time, the rotating rod 6, the fixed rod 5, the clamping block 4 and the connecting plate 7 rotate synchronously with the deviation adjusting idler bracket 2. When the deviation adjusting idler bracket 2 rotates to the target angle, the thrust on the pawl 9 is released, and the elastic force of the spring 11 drives the pawl 9 to be re-engaged in the tooth groove of the ratchet wheel 8. At this time, the rotating direction of the rotating rod 6 is a one-way rotation. The rotating rod 6 and the clamping block 4 are driven by the fixed rod 5 to rotate in the clockwise direction to make the clamping block 4 engaged in the corresponding tooth groove of the serrated disc 3. At this time, the position of the deviation adjusting idler bracket 2 is fixed, effectively solving the problem that the upper deviation adjusting idler bracket swings back and forth during the operation of the belt conveyor, eliminating wire bundling, more accurately adjusting the deviation of the belt conveyor, and enabling the belt conveyor to operate safely.

[0047] The above are only the preferred embodiments of the present utility model, and do not impose any limitations on the present utility model. Any simple modifications, changes, and equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model still fall within the scope of protection of the technical solution of the present utility model.
