Description

Technical Field

[0001] This utility model relates to the field of support roller technology, and in particular to a high-strength support roller structure. Background Technology

[0002] Track rollers typically consist of components such as a wheel body, axle, bearings, and end caps. The wheel body is mounted on the axle via bearings to achieve relative rotation. The axle ends are fixedly connected to the equipment frame or support structure. Track rollers are the core load-bearing components of tracked construction machinery (such as excavators, bulldozers, pavers, etc.), directly contacting the track tracks and bearing the equipment's own weight and impact loads during operation. Their structural strength and ease of assembly and disassembly directly affect the equipment's working efficiency and maintenance costs.

[0003] In practical use, traditional track rollers are often fastened with bolts or welded to the equipment frame. Bolted connections require the removal of multiple bolts one by one, especially in field operations or muddy environments, where bolts are prone to rust and jamming, making disassembly time-consuming and laborious. Welded connections cannot be repeatedly disassembled and reassembled, and require cutting and separation during maintenance and replacement, which not only damages the structural strength but also significantly prolongs downtime, making it inconvenient for subsequent quick replacement.

[0004] To address this, a high-strength support roller structure is proposed. Utility Model Content

Bolted connections require the removal of multiple bolts one by one, especially in field operations or muddy environments, where bolts are prone to rust and jamming, making disassembly time-consuming and laborious. Welded fixation cannot be repeatedly disassembled and reassembled, and cutting and separation are required for maintenance and replacement, which not only damages the structural strength but also significantly prolongs downtime, making it inconvenient for subsequent quick replacement.

[0026] 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.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A high-strength support roller structure includes a wheel body 1. An axle 2 is rotatably mounted inside the wheel body 1 via bearings. Both ends of the axle 2 are provided with axle heads 3. A quick-release mechanism 4 is fixedly connected to the top of the surface of the axle head 3. The quick-release mechanism 4 includes a connecting component 41 and a fixing component 42. The connecting component 41 includes a first connecting block 411 and a second connecting block 412. The first connecting block 411 is welded to the top of the surface of the axle head 3. The second connecting block 412 is disposed on top of the first connecting block 411 and the first connecting block 411 and the second connecting block 412 cooperate with each other. A T-shaped groove 413 is opened on the front side of the first connecting block 411. A T-shaped block 414 is fixedly connected to the bottom of the second connecting block 412 and cooperates with the T-shaped groove 413.

[0029] In this embodiment: by setting the connecting component 41, the first connecting block 411 is welded and fixed to the surface of the shaft head 3, which can provide an installation base for the entire quick-release mechanism 4; the second connecting block 412 is the connecting carrier of the equipment frame, which can cooperate with the first connecting block 411 to achieve docking; the T-slot 413 can provide precise guidance and limiting function, guide the T-block 414 to be inserted, and ensure that the first connecting block 411 and the second connecting block 412 will not loosen in the vertical direction due to vibration or load when docking, while increasing the contact area to disperse stress and improve the connection strength. At the same time, when the T-block 414 can be inserted into the T-slot 413, preliminary fixation can be achieved through shape matching, providing a basis for the subsequent locking of the fixing component 42, avoiding lateral displacement during docking, and ensuring installation accuracy.

[0030] Specifically, such as Figure 5 As shown, the fixing component 42 includes multiple fixing rods 421. The first connecting block 411 has multiple cavities inside, and the fixing rods 421 pass through the cavities and extend into the interior of the T-shaped groove 413.

[0031] Specifically, such as Figure 5 As shown, the surface of the T-shaped block 414 is provided with a positioning groove 422, and the positioning groove 422 is used in conjunction with the fixing rod 421.

[0032] Specifically, such as Figure 6 As shown, a mounting ring 423 is fixedly sleeved on the surface of the fixing rod 421 and the mounting ring 423 is movably connected inside the cavity. A fastening spring 424 is sleeved on one end of the fixing rod 421 inside the cavity. The two ends of the fastening spring 424 are fixedly connected to the mounting ring 423 and the inner wall of the cavity, respectively.

[0033] Specifically, such as Figure 6 As shown, a linkage plate 425 is fixedly connected to the outer side of the fixing rod 421, and a handle 426 is fixedly connected to the surface of the linkage plate 425.

[0034] Specifically, such as Figure 6 As shown, a front baffle 427 is attached to the front side of the T-shaped groove 413, and the side of the front baffle 427 near the linkage plate 425 is fixedly connected to the linkage plate 425.

[0035] In this embodiment: by setting the fixing component 42, the fixing rod 421 can be engaged into the positioning groove 422 of the T-block 414, and the axial displacement of the T-block 414 is restricted by the rigid fit, thereby preventing the T-block 414 from coming out of the T-groove 413; the cavity can provide installation space for the fixing rod 421, the mounting ring 423 and the fastening spring 424, while constraining the movement trajectory of the fixing rod 421, ensuring that the fixing rod 421 is accurately aligned with the positioning groove 422; the mounting ring 423 is fixed to the surface of the fixing rod 421 and can move synchronously with the fixing rod 421; the fastening spring 424 is normally in a stretched state, and can drive the fixing rod 421 to always be in a stretched state by pulling the mounting ring 423. The T-shaped block 414 tends to retract into the T-slot 413, achieving automatic locking after insertion and ensuring it does not loosen under vibration or impact conditions. The linkage plate 425 can connect multiple fixing rods 421 into one unit. By pulling the handle 426, all fixing rods 421 can be moved outward against the tension spring force, disengaging from the positioning slot 422, thus unlocking multiple fixing points in one operation and greatly improving disassembly efficiency. The front baffle 427 is fixed to the linkage plate 425. When the fixing rods 421 are locked, the front baffle 427 will fit against the front side of the T-slot 413, thereby sealing the opening end of the T-slot 413, preventing the T-shaped block 414 from accidentally sliding out from the front end, and enhancing the overall structural protection.

[0036] Specifically, such as Figure 2 As shown, sealing rings 5 ​​are provided inside both ends of the wheel body 1, and end caps 6 are fixedly connected to the outside of the sealing rings 5. Both the end caps 6 and the sealing rings 5 ​​are sleeved on the surface of the wheel axle 2.

[0037] Specifically, such as Figure 2 As shown, both ends of the wheel body 1 are provided with annular grooves 7. An annular block 8 is fixedly connected to the side of the end cover 6 near the annular groove 7. The annular block 8 is used in conjunction with the annular groove 7. The inside of both ends of the wheel body 1 is threaded with a first screw 9. The surface of the annular block 8 is provided with a first threaded groove 10 and the first screw 9 is used in conjunction with the first threaded groove 10.

[0038] In this embodiment: With the above settings, the sealing ring 5 is a sealing component at both ends of the wheel body 1. Its main function is to prevent external impurities such as mud and water from entering the interior of the wheel body 1. The end cap 6 can provide a mounting carrier for the sealing ring 5. This prevents the lubricating oil inside the wheel body 1 from leaking along the wheel axle 2, and at the same time blocks external impurities from entering through the gap between the wheel axle 2 and the end cap 6. The annular groove 7 can be used in conjunction with the annular block 8. The two can form a concave-convex fit structure. When the annular block 8 is embedded in the annular groove 7, the annular block 8 and the end cap 6 can be fastened in the annular groove 7 of the wheel body 1 by the first screw 9, so that the annular block 8 and the annular groove 7 fit tightly and the sealing ring 5 is in close contact with the wheel axle 2, ensuring that the sealing ring 5 will not loosen under vibration or impact conditions.

[0039] Specifically, such as Figure 5 As shown, both ends of the surface of the wheel axle 2 are provided with alignment grooves 12, and the inner wall of the shaft head 3 is fixedly connected with an alignment block 11, which is used in conjunction with the alignment groove 12.

[0040] Specifically, such as Figure 5 As shown, the surfaces at both ends of the axle 2 are provided with second threaded grooves 13, and the internal threads of the axle head 3 are connected with second screws 14, which are used in conjunction with the second threaded grooves 13.

[0041] In this embodiment: With the above configuration, the alignment block 11 is a raised structure on the surface of the axle 2, and the alignment groove 12 is a groove that fits the inner wall of the axle head 3. The two can form a concave-convex fit. When installing the axle head 3, by embedding the alignment block 11 into the alignment groove 12, the installation position of the axle 2 and the axle head 3 can be quickly calibrated, avoiding uneven force on the axle head 3 or installation deviation of the quick-release mechanism 4 due to misalignment. After the alignment block 11 and the alignment groove 12 are positioned, the axial preload of the second screw 14 can firmly fix the axle head 3 to the surface of the axle 2, preventing axial movement or circumferential slippage under heavy load, impact or vibration conditions. This ensures that the load is stably transmitted from the axle 2 to the axle head 3, and then transmitted to the equipment frame through the quick-release mechanism 4. At the same time, it facilitates the disassembly and maintenance of the axle head 3 in the later stage, further improving the flexibility of use.

[0042] Working principle: First, pull the handle 426 on the surface of the linkage plate 425. The handle 426 drives all the fixing rods 421 to move outward against the elastic force of the fastening spring 424, causing the fixing rods 421 to disengage from the positioning groove 422 of the T-block 414. At the same time, the front baffle 427 will move away from the front side of the T-slot 413 along with the linkage plate 425, exposing the opening. Then, the T-block 414, which is pre-fixed to the bottom of the equipment frame, is aligned with the T-slot 413 on the front side of the first connecting block 411, and then pushed in axially along the T-slot 413 until the T-block 414 is completely embedded in the T-slot 413. After the T-block 414 is installed in place, release the handle 426. Under the tension of the fastening spring 424, the fixing rods 421 will automatically snap into the positioning groove 422 on the surface of the T-block 414. At the same time, the linkage plate 425 will drive the front baffle 427 to conform to the T-block. The front side of the groove 413 is closed to complete the fixed connection between the wheel body 1 and the equipment frame. When the wheel body 1 is working, it will contact the track and bear the load of the equipment. The wheel body 1 rotates around the fixed axle 2. The sealing ring 5 can block the intrusion of external mud and sand, prevent internal lubricating oil leakage, and protect the internal bearing. When the wheel body 1 needs to be repaired or replaced, the handle 426 is pulled outward again. The handle 426 will drive all the fixing rods 421 to move outward against the elastic force of the fastening spring 424 through the linkage plate 425, so that the fixing rods 421 are disengaged from the positioning groove 422 of the T-block 414. At the same time, the front baffle 427 will leave the front side of the T-groove 413 along with the linkage plate 425, exposing the opening of the T-groove 413. Then, the T-block 414 is pulled out along the axis of the T-groove 413 to complete the separation of the axle head 3 from the equipment frame.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
