Description

Technical Field

[0001] This utility model relates to the field of track plate technology, and in particular to a rubber-coated track plate device with adjustable tension. Background Technology

[0002] In numerous industrial sectors and specialized operational scenarios, such as construction machinery, agricultural equipment, and mining machinery, rubber-coated track pads play a crucial role. They not only provide powerful traction but also adapt to various complex terrains and harsh working conditions, ensuring stable equipment operation. With continuous technological advancements and increasingly diverse application scenarios, the performance requirements for rubber-coated track pads are becoming increasingly stringent, especially in terms of tension adjustment. Precise and efficient adjustment mechanisms have become a key factor in improving the overall efficiency of the equipment. Therefore, developing an adjustable tension rubber-coated track pad device has significant practical implications and broad application prospects.

[0003] In traditional rubber-coated track pad technology, the common mechanical structure relies on simple bolt tightening and nut adjustment to change the track pad tension. The technical principle is to manually rotate the nuts, changing the relative positions of the connecting parts and thus adjusting the track pad tension. This adjustment method usually depends on the operator's experience and judgment, lacking precise quantitative standards. In actual operation, the operator often needs to repeatedly adjust and visually observe the track pad tension to achieve a roughly suitable level.

[0004] Traditional adjustment methods struggle to precisely adjust track shoe tension to the optimal operating state for the equipment. This results in either excessively loose track shoe tension, causing slippage between the track shoe and drive wheel, reducing power transmission efficiency and affecting normal operating speed and work progress, or excessively tight tension, increasing wear between the track shoe and other components. This not only shortens the track shoe's lifespan but may also cause malfunctions in other related components, significantly reducing the stability and reliability of the equipment, increasing maintenance costs and downtime, and severely hindering efficient operation under complex and variable working conditions. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable tension rubber-coated track plate device, which aims to improve the problem that traditional adjustment methods are difficult to accurately adjust the tension of the track plate to the optimal state for equipment operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable tension rubber-coated track plate device, comprising a track body, a fixing frame provided on one side of the outer wall of the track body, an inner plate fixedly connected inside the fixing frame, a track support wheel and an auxiliary wheel rotatably connected inside the inner plate, the track support wheel and the track body and the auxiliary wheel and the track body being meshed and connected, a push plate rotatably connected to the outer wall of the track support wheel, a connecting plate fixedly connected to the inner wall of the push plate, a push rod fixedly connected to one side of the connecting plate, and an adjustment component provided at one end of the push rod;

[0007] The adjustment assembly includes a triangular sliding plate and a second push plate. The outer wall of the triangular sliding plate is fixedly connected to one end of the push rod. A fixing plate is fixedly connected to the outer wall of the inner plate. A handwheel is rotatably connected inside the fixing plate. A telescopic rod is fixedly connected to one end of the handwheel. A threaded rod is fixedly connected to one end of the telescopic rod. The inner thread of the second push plate is threadedly connected to the outer wall of the threaded rod.

[0008] Furthermore, a limit wheel is fixedly connected to the outer wall of the handwheel, a fixing ring is fixedly connected to the outer wall of the telescopic rod near the handwheel, and a reset assembly is provided on the outer wall of the telescopic rod.

[0009] Furthermore, the reset assembly includes a movable ring and a spring, both of which are sleeved on the outer wall of the telescopic rod.

[0010] Furthermore, one end of the spring is fixedly connected to the outer wall of the movable ring, and the other end of the spring is fixedly connected to the outer wall of the fixed ring.

[0011] Furthermore, both the fixed ring and the movable ring are slidably connected inside the fixed plate, and the fixed ring and the movable ring are used to drive the spring to extend and retract.

[0012] Furthermore, the outer wall of the limiting wheel is slidably connected to the inside of the fixed frame, and the limiting wheel is used to limit the handwheel.

[0013] Furthermore, the inner wall of the second pusher plate is slidably connected to the outer wall of the triangular slide plate, and the second pusher plate is used to drive the triangular slide plate to move.

[0014] Furthermore, the outer wall of the triangular sliding plate is slidably connected to the inside of the inner plate, and the triangular sliding plate is used to drive the push plate to move.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the drive handwheel drives the telescopic rod and the threaded rod to rotate. By utilizing the threaded relationship between the two and the push plate two, the triangular slide plate is pushed to move precisely on the inner plate. Through the push rod and the connecting plate, the push plate one and the track roller are driven to achieve efficient and precise tension adjustment. Compared with traditional devices, its adjustment accuracy is higher. It can quickly adjust the track plate tension according to actual needs, improve the stability and reliability of equipment operation, reduce failures caused by improper tension, and extend the service life of the equipment.

[0017] 2. In this utility model, when driving the handwheel, pulling the handwheel outward causes the limit wheel to slide within the fixed frame. After disengaging, the handwheel can be rotated to adjust the tension. During this process, the telescopic rod drives the fixed ring and spring to stretch and store energy. Once the adjustment is complete, the spring rebounds, causing the limit wheel to return to its position, thus firmly limiting the handwheel, enhancing its stability, and preventing it from loosening due to external forces such as vibration, thus preventing changes in the track tension. This ensures that the track tension remains constant during equipment operation, improving safety and sustainability, and reducing maintenance work and equipment operating costs caused by a loose handwheel.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 4 This utility model provides an embodiment of an adjustable tension rubber-coated track plate device, comprising a track body 1, a fixing frame 3 provided on one side of the outer wall of the track body 1, an inner plate 5 fixedly connected inside the fixing frame 3 to provide a sliding track for the triangular slide plate 8, ensuring that the triangular slide plate 8 slides smoothly along a pre-designed path, a track support roller 2 and an auxiliary roller 18 rotatably connected inside the inner plate 5, the track support roller 2 and the track body 1, and the auxiliary roller 18 and the track body 1 are all meshed together, the outer wall of the track support roller 2 is rotatably connected to a push plate 4, which moves under the drive of a connecting plate 6 to assist... The track roller 2 adjusts the tension of the rubber-coated track plate and works in conjunction with the track roller 2 to act on the track plate. The inner wall of the push plate 4 is fixedly connected to the connecting plate 6, which is displaced under the action of the push rod 7. Through the connection structure with the push plate 4 and the track roller 2, the push plate 4 and the track roller 2 move synchronously, and finally realize the adjustment of the tension of the rubber-coated track plate. The push rod 7 is fixedly connected to one side of the connecting plate 6, connecting the triangular slide plate 8 and the connecting plate 6, accurately transmitting the force generated by the sliding of the triangular slide plate 8 to the connecting plate 6, pushing the connecting plate 6 to move. One end of the push rod 7 is provided with an adjustment component.

[0027] The adjustment assembly includes a triangular sliding plate 8 and a push plate 10, which move linearly under the drive of a threaded rod 9. The inclined surface at the front end of the push plate 8 is in contact with the side of the triangular sliding plate 8. The direction of the force is changed by the pushing action of the inclined surface, causing the triangular sliding plate 8 to slide inside the inner plate 5, thereby realizing the transmission and conversion of force. The outer wall of the triangular sliding plate 8 is fixedly connected to one end of the push rod 7. A fixing plate 12 is fixedly connected to the outer wall of the inner plate 5. A handwheel 11 is rotatably connected inside the fixing plate 12. Rotating the handwheel 11 provides the initial power for the tension adjustment of the entire device, driving the telescopic rod 17 to rotate. One end of the handwheel 11... A telescopic rod 17 is fixedly connected to the threaded rod 9, which transmits the rotational force of the drive handwheel 11 to the threaded rod 9, causing the threaded rod 9 to rotate synchronously. On the other hand, when adjusting the position of the handwheel 11, it can be stretched to match the movement of the handwheel 11, while simultaneously moving one end of the fixed ring 14 and the spring 16. One end of the telescopic rod 17 is fixedly connected to the threaded rod 9, which is connected to the push plate 2 10 by a thread. Utilizing the principle of thread transmission, its own rotation is converted into the linear movement of the push plate 2 10, providing power for the push plate 2 10 to push the triangular slide plate 8. The internal thread of the push plate 2 10 is connected to the outer wall of the threaded rod 9.

[0028] Specifically, the operator applies rotational force to the drive handwheel 11. Thanks to its robust structural design, the handwheel 11 efficiently transmits the operator's power, causing the closely connected telescopic rod 17 to rotate as well. The telescopic rod 17 is made of high-strength alloy material, possessing excellent torsional resistance and maintaining stability during rotation. Simultaneously, it drives the internally nested threaded rod 9 to rotate synchronously. The surface of the threaded rod 9 undergoes high-precision thread machining, precisely matching the internal threaded hole of the push plate 10. As the threaded rod 9 rotates, based on the threaded transmission principle, the push plate 10 moves linearly along the axial direction under the action of the threaded rod 9. The front end of the push plate 10 is carefully designed as a bevel at a specific angle. During movement, the inclined plane will closely fit the side of the triangular sliding plate 8, and the pushing action of the inclined plane will drive the triangular sliding plate 8 to slide smoothly along the pre-designed track inside the inner plate 5. The triangular sliding plate 8 has a unique shape, and its sliding process can effectively change the direction of force transmission. Through the push rod 7 connected to it, the force is accurately transmitted to the connecting plate 6. The connecting plate 6 has a sturdy structure and can withstand a large tensile force. Under the action of the push rod 7, it will be displaced, and then, through its connection structure with the push plate 4 and the track roller 2, it will drive the push plate 4 and the track roller 2 to move synchronously. The movement of the track roller 2 ultimately realizes the precise adjustment of the tension of the rubber-coated track plate, meeting the strict requirements of track plate tension under different working conditions.

[0029] Reference Figure 1 , Figure 4 and Figure 5A limit wheel 13 is fixedly connected to the outer wall of the handwheel 11. When the handwheel 11 moves outward, it slides inside the fixed frame 3. When it completely disengages from the fixed frame 3, the limit on the handwheel 11 is released, allowing the handwheel 11 to rotate freely for tension adjustment. After adjustment, it returns to the fixed frame 3 under the rebound action of the spring 16, limiting the handwheel 11 and preventing it from loosening. A fixing ring 14 is fixedly connected to the outer wall of the telescopic rod 17 near the handwheel 11. A reset assembly is provided on the outer wall of the telescopic rod 17, which includes a movable ring 15 and a spring 16. When adjusting the position of the handwheel 11, it is stretched and stores elastic potential energy. After adjustment, the rebound force drives the limit wheel 13 back to the fixed frame 3 through the fixing ring 14 and the telescopic rod 17, limiting the handwheel 11 and ensuring the stability of the handwheel 11, preventing it from loosening. Both the movable ring 15 and the spring 16 are... A spring 16 is fitted onto the outer wall of the telescopic rod 17. One end of the spring 16 is fixedly connected to the outer wall of the movable ring 15, and the other end of the spring 16 is fixedly connected to the outer wall of the fixed ring 14. At the end of the telescopic rod 17, the spring 16 moves with the telescopic rod 17, causing one end of the spring 16 to move, thus stretching or rebounding the spring 16. The spring 16 and the telescopic rod 17 serve as a connection and force transmission. The fixed ring 14 and the movable ring 15 are both slidably connected inside the fixed plate 12. The fixed ring 14 and the movable ring 15 are used to drive the spring 16 to extend and retract. The outer wall of the limiting wheel 13 is slidably connected inside the fixed frame 3. The limiting wheel 13 is used to limit the handwheel 11. The inner wall of the push plate 2 10 is slidably connected to the outer wall of the triangular slide plate 8. The push plate 2 10 is used to drive the triangular slide plate 8 to move. The outer wall of the triangular slide plate 8 is slidably connected inside the inner plate 5. The triangular slide plate 8 is used to drive the push plate 1 4 to move.

[0030] Specifically, the operator first needs to pull the handwheel 11 outward. The handwheel 11 has a textured surface for easy gripping, making it convenient for the operator to apply force. As the handwheel 11 moves outward, the limiting wheel 13, which is coaxially mounted with the handwheel 11, slides inside the fixing frame 3. The inner surface of the fixing frame 3 is finely polished to ensure that the limiting wheel 13 slides smoothly and stably. When the limiting wheel 13 completely disengages from the inside of the fixing frame 3 under external force, the handwheel 11 is freed from its limiting constraint, and the operator can then freely drive the handwheel 11 to rotate, thus initiating the subsequent tension adjustment process. During the movement of the handwheel 11, the telescopic rod 17 connected to it is also stretched accordingly. The telescopic rod 17 is composed of multiple nestable telescopic tubes, possessing good... With good telescopic performance, as the telescopic rod 17 moves, the fixed ring 14 at its end and one end of the spring 16 connected to the fixed ring 14 are also moved, causing the spring 16 to gradually stretch and store elastic potential energy during this process. After the tension adjustment operation is completed, the spring 16 begins to rebound with its stored elastic potential energy. This rebound force is transmitted to the telescopic rod 17 through the fixed ring 14, which in turn drives the limit wheel 13 to slide along the internal track of the fixed frame 3 again until it returns to the initial limit position inside the fixed frame 3, thus achieving a firm limit on the handwheel 11. This effectively prevents the handwheel 11 from loosening due to vibration or other external interference during equipment operation, ensuring the stability and reliability of the tension adjustment of the rubber-coated track plate device.

[0031] Working principle: When the adjustable tension rubber-coated track plate device is needed, first drive the handwheel 11 to drive the telescopic rod 17 and the threaded rod 9 to rotate. Then, in conjunction with the threaded relationship between the threaded rod 9 and the push plate 10, the push plate 10 moves linearly with the rotation of the threaded rod 9. Thus, the inclined surface of the push plate 10 pushes the triangular slide plate 8 to move inside the inner plate 5. Then, the push rod 7 drives the connecting plate 6 to move. Then, the movement of the connecting plate 6 drives the push plate 4 and the track roller 2 to move, thereby realizing tension adjustment.

[0032] Furthermore, when driving the handwheel 11, first pull the handwheel 11 outward, thereby causing the limit wheel 13 to slide inside the fixed frame 3. When the limit wheel 13 is completely disengaged from the inside of the fixed frame 3, the handwheel 11 can be driven to rotate. During this process, the movement of the handwheel 11 will also cause the telescopic rod 17 to stretch. Then, the movement of the telescopic rod 17 will cause the fixed ring 14 and one end of the spring 16 to move, causing the spring 16 to stretch. After the tension is adjusted, the spring 16 will rebound and cause the limit wheel 13 to return to the inside of the fixed frame 3, thereby limiting the handwheel 11 and preventing it from loosening.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
