Description

Technical Field

[0001] The utility model relates to the technical field of a tensioner bracket, and relates to a suspension structure of a tensioner bracket. Background Art

[0002] A tensioner bracket is a device used in a conveyor belt system to keep the conveyor belt taut and ensure its normal operation. The function of the tensioner bracket is to maintain the tension of the conveyor belt, prevent the conveyor belt from loosening or slipping, and at the same time can extend the service life of the conveyor belt;

[0003] A tensioner is usually used in the belt drive part of an engine drive system to tension the transmission belt by adjusting the position of the tensioner. However, after the transmission belt is tensioned by the tensioner, the transmission belt is generally in a relatively taut state. During the driving of the vehicle, the transmission belt may be slightly shaken due to the movement of the vehicle. During the long-term use of the transmission belt, in the case of shaking of the taut transmission belt, a pulling situation may occur. The length of the pulled transmission belt will increase during long-term pulling, which may affect the tensioning effect of the tensioner on the transmission belt, and thus may lead to a reduction in transmission efficiency;

[0004] To solve the above problems, a suspension structure of a tensioner bracket is proposed in this application. Summary of the Utility Model

[0005] The utility model aims at the technical problems existing in the prior art and provides a suspension structure of a tensioner bracket.

[0008] By setting the fixed sleeve, the second spring, the telescopic rod, the connecting strip and the cleaning rod, the dust on the conveyor belt can be cleaned, so as to prevent the dust on the conveyor belt from falling above the tension pulley body, and further prevent excessive dust on the tension pulley body from affecting the tensioning effect on the conveyor belt.

[0009] Preferably, a soft pad is fixedly connected to the outer wall of the telescopic rod, and one side of the soft pad is fixedly connected to one side of the connecting strip.

[0010] By setting the soft pad, the protection of the connecting strip and the fixed sleeve can be realized, so as to slow down the time of damage.

[0011] Preferably, one end of the convex block is rotatably connected to a threaded tube, a through hole is opened on the support plate, the threaded tube penetrates through the through hole opened on the support plate, and a bolt is threadedly connected to the inner wall of the threaded tube, and one side of the bolt is attached to one side of the support plate.

[0012] By setting the threaded tube, the through hole and the bolt, the movement of the convex block and the first spring can be realized, so as to facilitate the tensioning of the conveyor belt by the tension pulley body.

[0013] Preferably, a protective stripe is opened on one side of the bolt.

[0014] By setting the protective stripe on the bolt, the fixing of the convex block can be realized, so as to prevent the convex block from shaking, and further prevent the shaking of the convex block from affecting the tensioning effect of the tension pulley body on the conveyor belt.

[0015] Preferably, a limiting plate is fixedly connected to the bottom of the rotating frame, and a limiting shell is fixedly connected to the inner wall of the support frame.

[0016] By setting the limiting plate and the limiting shell, the limiting of the rotating frame and the tension pulley body can be realized, so as to prevent the tensioning effect of the tension pulley body on the conveyor belt from being affected.

[0017] The beneficial effects of the present utility model are:

When the vehicle is driving, when encountering a relatively steep ground, the conveyor belt may shake during the driving of the vehicle. During the shaking of the conveyor belt, the tension pulley body will continuously tension the conveyor belt under the pulling of the first spring, so as to effectively prevent the conveyor belt from becoming loose.

[0019] Through the mutual cooperation of the fixed sleeve, the second spring, the telescopic rod, the connecting bar and the cleaning rod, the dust on the conveyor belt is cleaned. When the vehicle is running, the dust may adhere to the outer surface of the conveyor belt. The cleaning rod scrapes the adhered dust, thus preventing the dust on the conveyor belt from falling above the tensioning wheel body, and further preventing excessive dust on the tensioning wheel body from affecting the tensioning effect on the conveyor belt.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the present application.

[0029] Referring to Figures 1-3 , a tensioner bracket suspension structure includes a support frame 1 and a conveyor belt 9 drivingly connected between two connecting wheels. A rotating frame 3 is rotatably connected to the top of the support frame 1. The support frame 1 is used to connect the rotating frame 3 above the vehicle. One end of the rotating frame 3 away from the support frame 1 is rotatably connected to a tensioner body 4. The rotating frame 3 is used to adjust and fix the tensioner body 4. The outer wall of the tensioner body 4 is in contact with the outer wall of the conveyor belt 9. The tensioner body 4 is used to tension the conveyor belt 9. A connecting plate 5 is fixedly connected to the side wall of the rotating frame 3. One end of the connecting plate 5 is rotatably connected to a first spring 6. The connecting plate 5 is used to fix the connecting plate 5 and facilitate the rotation of the connecting plate 5. A support plate 2 is fixedly connected to the top of the support frame 1. The support frame 1 is used to fix the support plate 2. A convex block 8 is rotatably connected inside the support plate 2. The outer wall of the convex block 8 is fixedly connected to one end of the first spring 6 away from the connecting plate 5. The convex block 8 is used to fix the first spring 6 and realize the rotation of the first spring 6. One side of the support plate 2 is fixedly connected to a cylinder 7. One end of the cylinder 7 is rotatably connected to a transmission wheel on the engine. The cylinder 7 is used to fix the support plate 2 to prevent the support plate 2 from shaking.

[0030] Referring to Figures 1-3, on the side of the rotating frame 3 away from the connecting plate 5, there is a fixed sleeve 10 fixedly connected. Inside the fixed sleeve 10, there is a second spring 11 fixedly connected. The fixed sleeve 10 is used to fix the second spring 11. One end of the second spring 11 is fixedly connected to a telescopic rod 12. The second spring 11 is used to move the telescopic rod 12. The outer wall of the telescopic rod 12 is in contact with the inner wall of the fixed sleeve 10. One end of the telescopic rod 12 away from the second spring 11 is fixedly connected to a connecting bar 13. The telescopic rod 12 is used to connect the connecting bar 13 to the second spring 11, so that the expansion and contraction of the second spring 11 can act on the connecting bar 13. A cleaning rod 14 is rotatably connected to the side wall of the connecting bar 13. The connecting bar 13 is used to connect the cleaning rod 14. The cleaning rod 14 is used to clean the dust on the conveyor belt 9, so as to prevent the dust on the conveyor belt 9 from falling above the tension pulley body 4, and further prevent too much dust on the tension pulley body 4 from affecting the tensioning effect on the conveyor belt 9.

[0031] Refer to Figure 3 , a soft pad 15 is fixedly connected to the outer wall of the telescopic rod 12. One side of the soft pad 15 is fixedly connected to one side of the connecting bar 13. The soft pad 15 is used to protect the connecting bar 13 and the fixed sleeve 10. When the vehicle is driving on a relatively steep road surface, the connecting bar 13 and the fixed sleeve 10 may collide with each other due to vibration, resulting in damage. The soft pad 15 is used to protect the collision part of the connecting bar 13 and the fixed sleeve 10, so as to slow down the time of damage.

[0032] Refer to Figure 1 and Figure 4 , one end of the convex block 8 is rotatably connected to a threaded pipe 16. A through hole 17 is opened on the support plate 2. The threaded pipe 16 passes through the through hole 17 opened on the support plate 2. A bolt 18 is threadedly connected to the inner wall of the threaded pipe 16. One side of the bolt 18 is in contact with one side of the support plate 2. The cooperation of the threaded pipe 16, the through hole 17 and the bolt 18 can move the convex block 8 and the first spring 6. By moving the convex block 8 and the first spring 6, the position of the tension pulley body 4 can be adjusted, so as to facilitate the tension pulley body 4 to tension the conveyor belt 9.

[0033] Refer to Figure 1 and Figure 2 , anti-slip stripes are opened on one side of the bolt 18. The anti-slip stripes provided on the bolt 18 are used to fix the convex block 8. Through the anti-slip stripes, the joint between the bolt 18 and the support plate 2 is made closer, so as to prevent the convex block 8 from shaking, and further prevent the shaking of the convex block 8 from affecting the tensioning effect of the tension pulley body 4 on the conveyor belt 9.

[0034] Refer to Figure 1 and Figure 4The bottom of the rotating frame 3 is fixedly connected to a limiting plate 20, and the inner wall of the supporting frame 1 is fixedly connected to a limiting shell 19. The coordinated use of the limiting plate 20 and the limiting shell 19 can realize the limitation of the rotating frame 3 and the tensioning wheel body 4. When the vehicle encounters a too steep road surface during driving, the conveyor belt 9 may shake slightly, causing the rotating frame 3 to swing up and down. The coordinated use of the limiting shell 19 and the limiting plate 20 can limit the swing of the rotating frame 3, thereby avoiding affecting the tensioning effect of the tensioning wheel body 4 on the conveyor belt 9.

[0035] Working principle:

[0036] The staff installs the device on the vehicle, and the threaded tube 16 can be moved by rotating the bolt 18. The movement of the threaded tube 16 can move the protrusion 8, so that the position and angle of the rotating frame 3 and the tensioning wheel body 4 can be adjusted, so that the tensioning wheel body 4 can tension the conveyor belt 9. During the driving of the vehicle, the conveyor belt 9 will shake during the movement of the vehicle. At this time, the shaking of the conveyor belt 9 will squeeze the tensioning wheel body 4, and the tensioning wheel body 4 will be stretched by the first spring 6 during the squeezing, thereby avoiding the conveyor belt 9 from shaking too violently, thereby avoiding affecting the tensioning effect of the conveyor belt 9. At the same time, during the driving of the vehicle, dust will fall into the outer surface of the conveyor belt 9 through the heat dissipation of the vehicle. The dust on the conveyor belt 9 can be cleaned by the cleaning rod 14, thereby avoiding dust accumulation on the tensioning wheel body 4, thereby avoiding affecting the tensioning effect of the tensioning wheel body 4 on the conveyor belt 9.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
