Abstract
Description
Technical Field
[0001] This disclosure relates to the field of suspension technology, and more particularly to a suspension structure and a vibrating screen. Background Technology
[0002] In existing technologies, the connection and fixation of wire ropes usually involves arranging the wire ropes in evenly distributed grooves using conical copper pins, then fixing the connection by locking with nuts, and adjusting the length and preload using wire rope tensioning rods.
[0003] When suspending the vibrating screen using the above method, friction points exist at the contact points between the wire rope and the locking nut. During screen operation, these friction points cause severe wear on the wire rope, leading to breakage. Furthermore, the contact points between the wire rope and the locking nut are also stress concentration points for the wire rope, accelerating wear and reducing its service life. These factors combined result in frequent wire rope breakage during actual use, severely impacting the operational safety and efficiency of the vibrating screen.
[0004] Therefore, how to provide a suspension structure that can reduce the wear of the wire rope and avoid stress concentration when the vibrating screen is working is an urgent problem to be solved. Utility Model Content
[0005] To address the aforementioned technical problems, this disclosure provides a suspension structure comprising: a fixing member, a flexible member, and an adjusting member, arranged sequentially along a vertical direction; the flexible member having a first winding end and a second winding end opposite each other along its extension direction; a first connecting member having a first annular surface on its outer periphery; a second connecting member having a second annular surface on its outer periphery; a locking member; the fixing member being rotatably connected to the first connecting member and located at the first winding end of the flexible member; one end of the adjusting member being rotatably connected to the second connecting member and located at the second winding end of the flexible member; and the other end of the adjusting member being used to suspend the object to be suspended; the first winding end of the flexible member extending along its extension direction after at least one turn around the first annular surface to form a first overlapping segment, and the first overlapping segment being locked by the locking member; the second winding end extending along its extension direction after at least one turn around the second annular surface to form a second overlapping segment, and the second overlapping segment being locked by the locking member.
[0006] In some embodiments, both the first connector and the second connector have a head and a tail, and the width of the head and the tail decreases along the first direction. The head and the tail smoothly transition to form a continuous curve, and the head of the first connector and the head of the second connector are arranged opposite to each other along the extension direction of the flexible member.
[0007] In some embodiments, the first connector has a first target hole, the second connector has a third target hole; the fixing member has a second target hole corresponding to the first target hole, the adjusting member has a fourth target hole corresponding to the third target hole; and a locking pin is used to connect the first target hole and the second target hole, and the third target hole and the fourth target hole are connected by a locking pin.
[0008] In some embodiments, the adjusting member includes: threaded rods, two threaded rods are arranged opposite each other in a vertical direction, and the outer peripheral surfaces of the two threaded rods are provided with threads of opposite patterns, the opposite ends of the two threaded rods are respectively used to connect the flexible member and the member to be suspended; and a connecting sleeve, threadedly connected to the two threaded rods, the connecting sleeve being able to rotate to bring the two threaded rods closer or further apart.
[0009] In some embodiments, the adjusting member includes: a safety buckle, and each of the two threaded rods having a mounting buckle at its two ends close to each other, the extension direction of the safety buckle forming an angle with the extension direction of the threaded rod, and the extension length of the safety buckle being greater than the length of the inner diameter of the connecting sleeve.
[0010] In some embodiments, the locking member includes: a fastening body having a U-shaped surface; a limiting portion sleeved on the fastening body and forming an annular locking area together with the U-shaped surface for clamping the flexible member; and a locking portion threadedly connected to the fastening body, capable of locking the limiting portion to a plurality of mounting positions on the fastening body.
[0011] In some embodiments, the first overlapping segment and the second overlapping segment each include at least two overlapping segments; the suspension structure further includes: a tightening sleeve, sleeved on the flexible member, the tightening sleeve having an annular groove, and the multiple overlapping segments being locked through the annular groove.
[0012] In some embodiments, the first annular surface and the second annular surface are respectively provided with a plurality of grooves, and the plurality of grooves correspond one-to-one with a plurality of overlapping segments.
[0013] A second aspect of this application provides a vibrating screen, including: a suspension structure as shown on the weight.
[0014] In some embodiments, the device further includes: a screen frame; and a plurality of suspension structures, the plurality of suspension structures being connected to the screen frame via respective adjusting members to suspend the screen frame.

The portion of the first winding end extending after winding around the first annular surface and between the first and second winding ends forms a first overlapping section, and the portion of the second winding end extending after winding around the second annular surface and between the first and second winding ends forms a second overlapping section. A locking member locks the flexible element in the first and second overlapping sections. The contact method, where the first winding end of the flexible element is wound with the first annular surface and the second winding end is wound with the second annular surface, increases the contact area between the flexible element and the first and second connectors, resulting in a more uniform stress distribution. Furthermore, the locking member is located in the first and second overlapping sections, rather than at the connection between the first connector and the first winding end or the connection between the second connector and the second winding end, thus avoiding excessive stress concentration at the connection points. The rotating connection between the fixed component and the first connecting component, and between the adjusting component and the second connecting component, allows the flexible component a certain degree of freedom under stress, reducing the impact and wear caused by rigid connections. Therefore, this suspension structure can effectively reduce the friction and wear of the wire rope, distribute stress, improve the reliability and safety of the connection, and extend the service life of the wire rope.

[0031] The inventors discovered that the vibrating screen for large-particle urea uses a wire rope suspension system, with four wire ropes attached to the four corners of the screen's base. These wire ropes are perpendicular to the ground and of equal length, with their lengths adjusted via tensioners. However, since its commissioning, the vibrating screen has experienced 3 to 5 wire rope breakage incidents annually. Each incident requires a shutdown of the granulation system for more than 4 hours, leading to reduced load operation and increased energy consumption in the urea plant. The breakage points are primarily concentrated at the contact point between the locking nut of the straight rod connector and the wire rope, indicating severe wear and stress concentration at this contact area.
[0032] This disclosure provides a suspension structure 13, including: a fixing member 1, a flexible member 2, and an adjusting member 3, arranged sequentially along a vertical direction A; the flexible member 2 has a first winding end 21 and a second winding end 22 opposite to each other along its extension direction; a first connecting member 4, with a first annular surface 41 on its outer periphery; a second connecting member 5, with a second annular surface 51 on its outer periphery; a locking member 6; the fixing member 1 is rotatably connected to the first connecting member 4 and located at the first winding end 21 of the flexible member 2; one end of the adjusting member 3 is rotatably connected to the second connecting member 5 and located at the second winding end 22 of the flexible member 2; the other end of the adjusting member 3 is used to suspend the suspended member 12; the first winding end 21 of the flexible member 2 extends along its extension direction after winding around the first annular surface 41 at least once to form a first overlapping segment 7, and the first overlapping segment 7 is locked by the locking member 6; the second winding end 22 extends along its extension direction after winding around the second annular surface 51 at least once to form a second overlapping segment 8, and the second overlapping segment 8 is locked by the locking member 6.
[0033] Specifically, such as Figure 1 As shown, the fixing component 1 is used to support the flexible component 2, the adjusting component 3, and the component 12 to be suspended, etc. The fixing component 1 can be a U-shaped closed-loop tube, one end of which can be fixed to the supporting frame 14 via bolts, clips, or other connectors, or it can be fixed to the supporting frame 14 by welding. The supporting frame 14 can be a wall, other supporting column, or a support frame. The fixing component 1 can also be a lifting eye bolt, lifting lug, or other structure. The flexible component 2 can deform to a certain extent under stress and is a component with a certain degree of flexibility. It can be a synthetic fiber rope or a steel strand made of multiple strands of fine steel wire. The length of the flexible component 2 can be selected according to actual needs and is not specifically limited here.
[0034] The first connecting member 4 connects the fixed member 1 and the flexible member 2, and the second connecting member 5 connects the flexible member 2 and the adjusting member 3. One end of the fixed member 1 can be rotatably connected to the first connecting member 4 via a rotating shaft. The first winding end 21 of the flexible member 2 can wrap around the first annular surface 41 on the outer peripheral surface of the first connecting member 4, and then wrap back to its body between the first winding end 21 and the second winding end 22, and overlap with its body to form a first overlapping section 7. The first overlapping section 7 is then locked by the locking member 6. The first winding end 21 can wrap around the first annular surface 41 once or multiple times before being locked by the locking member 6. The adjusting member 3 can extend and retract along the extension direction of the flexible member 2 to adjust the distance between the second winding end 22 and the suspended member 12. The adjusting member 3 can be a telescopic rod, a hydraulic cylinder, etc. One end of the adjusting member 3 can be rotatably connected to the second connecting member 5 via a rotating shaft. The second winding end 22 of the flexible member 2 can wrap around the second annular surface 51 on the outer peripheral surface of the second connecting member 5, and then wrap back to the body between its first winding end 21 and the second winding end 22, and overlap with the body to form a second overlapping section 8. The second overlapping section 8 is then locked by the locking member 6. The second winding end 22 can wrap around the second annular surface 51 once or multiple times before being locked by the locking member 6.
[0035] Through the above technical solution, the suspension structure 13 and vibrating screen provided in this disclosure connect the first winding end 21 of the flexible member 2 to the first annular surface 41 of the first connecting member 4, thereby connecting it to the fixing member 1. The second winding end 22 of the flexible member 2 is wound around the second annular surface 51 of the second connecting member 5, thereby connecting it to the member to be suspended 12. Furthermore, the portion of the first winding end 21 extending after winding around the first annular surface 41 and between the first winding end 21 and the second winding end 22 forms a first overlapping segment 7. Similarly, the portion of the second winding end 22 extending after winding around the second annular surface 51 and between the first winding end 21 and the second winding end 22 forms a second overlapping segment 8. Locking member 6 locks the flexible member 2 in the first overlapping section 7 and the second overlapping section 8. The first winding end 21 of the flexible member 2 is wound with the first annular surface 41, and the second winding end 22 is wound with the second annular surface 51. This contact method increases the contact area between the flexible member 2 and the first connecting member 4 and the second connecting member 5, resulting in a more uniform stress distribution. Furthermore, the locking member 6 is located in the first overlapping section 7 and the second overlapping section 8, rather than at the connection between the first connecting member 4 and the first winding end 21, or the connection between the second connecting member 5 and the second winding end 22, thus avoiding excessive stress concentration at the connection points. The rotational connection between the fixing member 1 and the first connecting member 4, and between the adjusting member 3 and the second connecting member 5, allows the flexible member 2 a certain degree of freedom under stress, reducing the impact and wear caused by rigid connections. Therefore, this suspension structure 13 can effectively reduce the friction and wear of the wire rope, disperse stress, improve the reliability and safety of the connection, and extend the service life of the wire rope.
[0036] In some embodiments, the first connector 4 and the second connector 5 are both provided with a head 43 and a tail 44, and the width of the head 43 to the tail 44 decreases along the first direction B. The head 43 and the tail 44 are smoothly transitioned to form a continuous curve, and the head 43 of the first connector 4 and the head 43 of the second connector 5 are arranged opposite to each other along the extension direction of the flexible member 2.
[0037] Specifically, such as Figure 1 , Figure 5 As shown, the heads 43 of the first connector 4 and the second connector 5 are wider to provide a larger contact area, allowing the flexible element 2 to be wound more stably. The tails 44 of the first connector 4 and the second connector 5 are narrower to reduce friction of the flexible element 2 during winding and ensure that the flexible element 2 can be smoothly wound from the annular surface to the body of the flexible element 2. The gradually decreasing width from the heads 43 to the tails 44 of the first connector 4 and the second connector 5 forms a continuous curve, allowing the flexible element 2 to gradually adapt to changes in the annular surface during winding. This ensures a smooth transition for the flexible element 2 during winding, reduces local stress concentration points, and improves the service life of the flexible element 2. In addition, the teardrop shape of the first connector 4 and the second connector 5 provides guidance and aesthetics, making the flexible element 2 easier to wind and reducing the risk of tangling and knotting.
[0038] In some embodiments, the first connector 4 is provided with a first target hole 42, the second connector 5 is provided with a third target hole 52; the fixing member 1 is provided with a second target hole 11 corresponding to the first target hole 42, the adjusting member 3 is provided with a fourth target hole corresponding to the third target hole 52; a locking pin 9 is used to connect the first target hole 42 and the second target hole 11, and the third target hole 52 and the fourth target hole are connected by a locking pin 9.
[0039] Specifically, such as Figure 1As shown, the first connecting member 4 has a first target hole 42, which penetrates the first connecting member 4 and can be positioned at the center of the first connecting member 4. The second connecting member 5 has a second target hole 11, which penetrates the second connecting member 5 and can be positioned at the center of the second connecting member 5. The fixing member 1 has a second target hole 11 corresponding to the first target hole 42. The fixing member 1 and the first connecting member 4 at least partially overlap in the extending direction of the flexible member 2, so that the first target hole 42 and the second target hole 11 correspond and are locked by a locking pin 9. The diameter of the first target hole 42 and the second target hole 11 can be greater than or equal to the outer diameter of the locking pin 9. The adjusting member 3 has a fourth target hole corresponding to the third target hole 52. The adjusting member 3 and the second connecting member 5 at least partially overlap in the extending direction of the flexible member 2, so that the third target hole 52 and the fourth target hole correspond and are locked by a locking pin 9. The diameter of the third target hole 52 and the fourth target hole can be greater than or equal to the outer diameter of the locking pin 9. Such a connection structure can maintain a stable connection between the fixing member 1 and the first connecting member 4, and between the adjusting member 3 and the second connecting member 5, while also ensuring that the fixing member 1 and the first connecting member 4, and between the adjusting member 3 and the second connecting member 5, have a certain degree of freedom, and prevent stress concentration at a certain point of connection.
[0040] In some embodiments, the adjusting member 3 includes: threaded rods 32, two threaded rods 32 are arranged opposite to each other along the vertical direction A, and the outer peripheral surfaces of the two threaded rods 32 are provided with threads of opposite patterns, and the two opposite ends of the two threaded rods 32 are respectively used to connect the flexible member 2 and the member to be suspended 12; and a connecting sleeve 33, which is threadedly connected to the two threaded rods 32, and the connecting sleeve 33 can rotate to make the two threaded rods 32 move closer or further apart.
[0041] Specifically, such as Figure 1 As shown, the outer circumferential surface of the threaded rod 32 is threaded, and the threads of the two threaded rods 32 are opposite in direction, one being a right-hand thread and the other a left-hand thread. The opposite ends of the two threaded rods 32 are used to connect the flexible component 2 and the suspended component 12, respectively. The connecting sleeve 33 has an internal thread that matches the external threads of the two threaded rods 32. The two threaded rods 32 are threaded together through the connecting sleeve 33 to form a whole. When it is necessary to shorten the distance between the two threaded rods 32, the connecting sleeve 33 is rotated clockwise. Since the threads of the two threaded rods 32 are opposite in direction, the rotation of the connecting sleeve 33 will cause the two threaded rods 32 to move inward simultaneously, thus bringing them closer together. When it is necessary to lengthen the distance between the two threaded rods 32, the connecting sleeve 33 is rotated counterclockwise. The rotation of the connecting sleeve 33 will cause the two threaded rods 32 to move outward simultaneously, thus moving them further apart. The adjusting component 3 can easily adjust the length and preload of the flexible component 2, improving the stability and reliability of the suspension structure 13.
[0042] In some embodiments, the adjusting member 3 includes a safety buckle, and each of the two threaded rods 32 is provided with a mounting buckle at its two ends that are close to each other. The extension direction of the safety buckle forms an angle with the extension direction of the threaded rods 32, and the extension length of the safety buckle is greater than the length of the inner diameter of the connecting sleeve 33.
[0043] Specifically, the extension direction of the safety buckle forms a certain angle with the extension direction of the threaded rod 32, such as 90° or 130°, and the length of the extended portion of the safety buckle is greater than the inner diameter of the connecting sleeve 33. The main body of the safety buckle can be U-shaped, C-shaped, or other similar shapes. One end of the safety buckle can be drilled and fixed to the threaded rod 32 with a pin. The other end of the safety buckle can be fitted with a spring lock to ensure that it automatically closes under force and prevents accidental opening. The safety buckle not only provides additional safety protection but also prevents the threaded rod 32 from completely separating in the event of loosening or failure of the connecting sleeve 33, thereby improving the stability and safety of the entire suspension structure 13.
[0044] In some embodiments, the locking member 6 includes: a fastening body 61 having a U-shaped surface 611; a limiting portion 62 sleeved on the fastening body 61 and forming an annular locking area together with the U-shaped surface 611 for clamping the flexible member 2; and a locking portion 63 threadedly connected to the fastening body 61, capable of locking the limiting portion 62 to multiple mounting positions of the fastening body 61.
[0045] Specifically, such as Figure 4 As shown, the fastening body 61 has a U-shaped surface 611 for accommodating the flexible member 2. A limiting part 62 is fitted onto the fastening body 61, forming an annular locking area together with the U-shaped surface 611. The locking part 63 is threadedly connected to the fastening body 61 and can be screwed into it. The locking part 63 can lock the limiting part 62 at different installation positions on the fastening body 61, thus accommodating different thicknesses of the flexible member 2. By screwing the locking part 63 into the threaded hole of the fastening body 61, the limiting part 62 is gradually pushed closer to the fastening body 61. The position of the locking part 63 can be adjusted as needed to firmly press the limiting part 62 onto the fastening body 61, thereby fixing the flexible member 2 within the locking area. The locking part 63 can be locked at multiple installation positions on the fastening body 61 to accommodate flexible members 2 of different thicknesses or different preload requirements. The locking part 63 presses the limiting part 62 into the appropriate position, and the flexible part 2 is firmly fixed in the locking area to prevent it from loosening or slipping during use. The preload can be increased by further tightening the locking part 63 to ensure the stability of the flexible part 2.
[0046] In some embodiments, the first overlapping segment 7 and the second overlapping segment 8 each include at least two overlapping segments; the suspension structure 13 further includes: a tightening sleeve 10, which is sleeved on the flexible member 2, the tightening sleeve 10 having an annular groove 101, and the multiple overlapping segments are locked by the annular groove 101.
[0047] Specifically, such as Figure 1 , Figure 3 As shown, the first overlapping segment 7 and the second overlapping segment 8 include at least two overlapping segments, meaning that the first winding end 21 winds around the first annular surface 41 at least twice, and the second winding end 22 winds around the second annular surface 51 at least twice. This increases the contact area between the two ends of the flexible member 2 and the connecting member, thus increasing the stress-bearing area and reducing local stress. The tightening sleeve 10 has an annular groove 101 for locking multiple overlapping segments. The tightening sleeve 10 can have multiple annular grooves 101, each corresponding to one overlapping segment, that is, each annular groove 101 engages one overlapping segment. The tightening sleeve 10 is designed as a ring structure, with the annular groove 101 located on the inner surface of the tightening sleeve 10. The tightening sleeve 10 can be fitted onto the first overlapping segment 7 and the second overlapping segment 8. The annular groove 101 securely fixes the multiple overlapping segments together, preventing them from sliding against each other and causing wear.
[0048] In some embodiments, the first annular surface 41 and the second annular surface 51 are respectively provided with a plurality of grooves, and the plurality of grooves correspond one-to-one with a plurality of overlapping segments.
[0049] Specifically, the first winding end 21 is wound around the first annular surface 41 of the first connecting member 4, with one groove corresponding to each turn. The second winding is wound around the second annular surface 51 of the second connecting member 5, with one groove corresponding to each turn. By setting multiple grooves, each turn of the flexible member 2 has its own independent space, avoiding direct contact between the turns and thus reducing mutual wear. When the vibrating screen vibrates, the segments of the flexible member 2 will not rub against each other, improving the durability of the system.
[0050] A second aspect of this application provides a vibrating screen, including a suspension structure 13.
[0051] The vibrating screens of this application include, but are not limited to, linear suspension vibrating screens, circular suspension vibrating screens, and high-frequency suspension vibrating screens. The vibrating screen provided in this disclosure connects the first winding end 21 of the flexible member 2 to the first annular surface 41 of the first connecting member 4, thus connecting it to the fixing member 1. The second winding end 22 of the flexible member 2 is wound around the second annular surface 51 of the second connecting member 5, thus connecting it to the member to be suspended 12. Furthermore, the portion of the first winding end 21 extending after winding around the first annular surface 41 and between the first winding end 21 and the second winding end 22 forms a first overlapping segment 7. The portion of the second winding end 22 extending after winding around the second annular surface 51 and between the first winding end 21 and the second winding end 22 forms a second overlapping segment 8. Locking member 6 locks the flexible member 2 in the first overlapping section 7 and the second overlapping section 8. The first winding end 21 of the flexible member 2 is wound with the first annular surface 41, and the second winding end 22 is wound with the second annular surface 51. This contact method increases the contact area between the flexible member 2 and the first connecting member 4 and the second connecting member 5, resulting in a more uniform stress distribution. Furthermore, the locking member 6 is located in the first overlapping section 7 and the second overlapping section 8, rather than at the connection between the first connecting member 4 and the first winding end 21, or the connection between the second connecting member 5 and the second winding end 22, thus avoiding excessive stress concentration at the connection points. The rotational connection between the fixing member 1 and the first connecting member 4, and between the adjusting member 3 and the second connecting member 5, allows the flexible member 2 a certain degree of freedom under stress, reducing the impact and wear caused by rigid connections. Therefore, this vibrating screen can effectively reduce the friction and wear of the wire rope, disperse stress, improve the reliability and safety of the connection, and extend the service life of the wire rope.
[0052] In some embodiments, the system further includes: a screen frame; and a plurality of suspension structures 13, the plurality of suspension structures 13 being connected to the screen frame via respective adjusting members 3 to suspend the screen frame.
[0053] Specifically, such as Figure 1 As shown, the screen frame is the main part of the suspended vibrating screen. It carries the screen mesh and material and is suspended from the support frame 14 by the suspension structure 13. The screen frame can be of any shape, such as a rectangular screen frame or a circular screen frame. The screen frame can be suspended by multiple suspension structures 13. There is no limit to the number of suspension structures 13, such as 4, 5, or 6. For example, four suspension structures 13 can be evenly arranged on the screen frame, and the screen frame can be suspended by the four suspension structures 13 together. Suspending the screen frame by the four suspension structures 13 ensures that the screen frame can move up and down evenly during vibration. In addition, by adjusting the length and preload of each suspension structure 13, the balance and vibration amplitude of the screen frame can be adjusted to optimize the screening effect.
