Description

Technical Field

[0001] This utility model relates to the field of excavator support roller technology, specifically a combined high wear-resistant excavator support roller. Background Technology

[0002] Track rollers are a crucial component of the excavator chassis. Their primary function is to transfer the excavator's weight to the ground and roll it along the tracks, while simultaneously preventing lateral slippage and ensuring stable operation. Track rollers are typically located between the lower surface of the left / right beams of the excavator chassis and the tracks; depending on the excavator's tonnage, there may be 5-10 on each side. Track rollers operate under harsh conditions, often in mud, water, and dust, and are subjected to strong impacts; therefore, they require excellent sealing, wear resistance, and low rolling resistance.

[0003] For example, Chinese Patent Application No. 202221645842.9 discloses a novel support roller, including a support roller shaft and a support roller body, end cap A, and end cap B sleeved on the support roller shaft. End cap A and end cap B are located on opposite sides of the support roller body. A first bearing and a second bearing are press-fitted into the support roller body. The support roller body is rotatably mounted on the support roller shaft via the first and second bearings. The inner holes of end caps A and B are both interference-fitted with the shaft ends of the support roller shaft. A first oil seal is installed between the support roller body and end cap A, and a second oil seal is installed between the support roller body and end cap B. The beneficial effects of this utility model are: Regarding the fit between the end caps and the shaft, generally, O-ring seals and retaining rings are used for sealing. This utility model uses interference fits between both ends of the support roller shaft and the end caps, eliminating the need for retaining rings and O-rings. This ensures more accurate axial clearance and reduces costs.

[0004] During the use of track rollers for excavators, the outer wheel body is often designed as a single piece. However, when the wheel body is worn out or damaged, the entire track roller needs to be replaced. This not only makes the replacement process complicated and cumbersome, but also results in excessively high maintenance costs and complicated replacement procedures.

[0005] Therefore, it is necessary to redesign and modify the support rollers of the combined high wear-resistant excavator to effectively prevent the occurrence of complex replacement and high maintenance costs. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a combined high wear-resistant excavator support roller, which has the advantages of being easy to use and solves the problems of complex replacement and high maintenance costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a combined high wear-resistant excavator support roller, comprising a support roller and a wear-resistant mechanism. The wear-resistant mechanism includes semi-circular rings movably connected to the front and rear sides of the support roller. Each semi-circular ring has an extension ring fixedly connected to its surface, and the extension ring has a wear-resistant ring fixedly connected to its surface. The wear-resistant ring has wear-resistant properties and is made of high-chromium alloy. The support roller has an anti-detachment mechanism on its surface.

[0008] As a preferred embodiment of this utility model, the anti-slip mechanism includes an arc-shaped ring movably connected to the surface of the semi-circular ring. The outer surface of the support roller is provided with multiple bolts, which fix the semi-circular ring and the arc-shaped ring to the surface of the support roller through threads. The surface of the arc-shaped ring is fixedly connected with multiple tooth blocks, which can prevent the track from falling off.

[0009] As a preferred embodiment of this invention, a reinforcing plate is fixedly connected to the inner side of the extension ring, and the inner side of the reinforcing plate is fixedly connected to the surface of the semi-circular ring.

[0010] As a preferred embodiment of this invention, the surface of the arc-shaped ring is fixedly connected with multiple protective rings, which can shield and protect the bolts.

[0011] As a preferred embodiment of this invention, a locking block is fixedly connected to the back of the front semicircular ring, and the locking block is inserted into the interior of the rear semicircular ring to facilitate the alignment and installation of the semicircular ring.

[0012] As a preferred embodiment of this invention, the surface of the extension ring is provided with an arc angle, which can prevent sharp edges from scratching the operator.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In practical use, the wear-resistant mechanism and the anti-detachment mechanism of this utility model work together. The wear-resistant mechanism, with its unique design and high-performance materials, significantly enhances the wear resistance of the support roller, effectively extending its service life. Simultaneously, the anti-detachment mechanism ensures the stable connection of related components, guaranteeing the stability of the overall structure. It is worth mentioning that the overall structure adopts a modular design concept. When external components, such as certain parts of the wear-resistant mechanism or the anti-detachment mechanism, become excessively worn or damaged, operators can quickly and conveniently replace and repair them without replacing the entire support roller. This modular design greatly simplifies the maintenance process, reduces maintenance costs and time, and makes it easy to use.

[0015] 2. By setting up an anti-detachment mechanism, the multiple toothed blocks on the surface of the arc-shaped ring can cooperate with the track, increasing the friction between the track and the support roller, effectively preventing the track from falling off due to vibration, impact, or other reasons during the operation of the support roller, ensuring the normal operation of the equipment, and avoiding safety accidents and equipment damage caused by track detachment.

[0016] 3. This utility model further strengthens the connection between the extension ring and the semi-circular ring by adding a reinforcing plate. During the operation of the support roller, it can withstand greater forces and vibrations, preventing the extension ring and the semi-circular ring from separating due to weak connection, thus ensuring the overall stability and reliability of the wear-resistant mechanism.

[0017] 4. This utility model, by setting a protective ring, can shield and protect the bolts, preventing them from being impacted or worn during equipment operation. As a crucial component of the fixing and anti-loosening mechanism, the integrity of the bolts is vital for the normal operation of the entire device. The protective ring effectively extends the service life of the bolts and reduces maintenance work caused by bolt damage.

[0018] 5. This utility model, by incorporating locking blocks, makes the alignment and installation of the semicircular rings more convenient and faster. During installation, operators can use the guiding effect of the locking blocks to quickly and accurately align and install the front and rear semicircular rings, improving installation efficiency and reducing installation time and labor costs.

[0019] 6. This utility model incorporates an arc angle. During equipment installation, maintenance, and repair, operators will come into contact with the extension ring. The arc angle design prevents operators from being injured by accidentally touching sharp edges, thus improving the safety and user-friendliness of the equipment. Attached Figure Description

The wear-resistant rings 4 have wear-resistant properties and are made of high chromium alloy. The surface of the support roller 1 is provided with an anti-detachment mechanism.

[0027] refer to Figure 2 The anti-slip mechanism includes an arc ring 5 movably connected to the surface of the semi-circular ring 2. Multiple bolts 6 are provided on the outer surface of the support roller 1. The bolts 6 fix the semi-circular ring 2 and the arc ring 5 to the surface of the support roller 1 through threads. Multiple tooth blocks 7 are fixedly connected to the surface of the arc ring 5. The tooth blocks 7 can prevent the track from falling off.

[0028] As a technical optimization of this utility model, by setting an anti-detachment mechanism, multiple toothed blocks 7 on the surface of the arc-shaped ring 5 can cooperate with the track, increase the friction between the track and the support roller 1, effectively prevent the track from falling off due to vibration, impact and other reasons during the operation of the support roller 1, ensure the normal operation of the equipment, and avoid safety accidents and equipment damage caused by track detachment.

[0029] refer to Figure 2 A reinforcing plate 8 is fixedly connected to the inner side of the extension ring 3, and the inner side of the reinforcing plate 8 is fixedly connected to the surface of the semi-circular ring 2.

[0030] As a technical optimization of this utility model, the connection strength between the extension ring 3 and the semi-circular ring 2 is further strengthened by setting the reinforcing plate 8. During the operation of the support roller 1, it can withstand greater force and vibration, preventing the extension ring 3 and the semi-circular ring 2 from separating due to weak connection, thus ensuring the overall stability and reliability of the wear-resistant mechanism.

[0031] refer to Figure 2 Multiple protective rings 9 are fixedly connected to the surface of the arc-shaped ring 5. The protective rings 9 can shield and protect the bolt 6.

[0032] As a technical optimization of this utility model, by setting a protective ring 9, the bolt 6 can be shielded and protected, preventing the bolt 6 from being impacted or worn during equipment operation. As an important component of the fixing and anti-loosening mechanism, the integrity of the bolt 6 is crucial to the normal operation of the entire device. The setting of the protective ring 9 can effectively extend the service life of the bolt 6 and reduce maintenance work caused by bolt 6 damage.

[0033] refer to Figure 3 A locking block 10 is fixedly connected to the back of the front semicircular ring 2. The locking block 10 is inserted into the interior of the rear semicircular ring 2 to facilitate the alignment and installation of the semicircular ring 2.

[0034] As a technical optimization of this utility model, the setting of the locking block 10 makes the alignment and installation of the semicircular ring 2 more convenient and faster. During the installation process, the operator can quickly and accurately align and install the front and rear semicircular rings 2 in place by using the guiding effect of the locking block 10, thereby improving installation efficiency and reducing installation time and labor costs.

[0035] refer to Figure 3 The surface of the extension ring 3 is provided with an arc angle 11, which can prevent sharp edges from scratching the operator.

The arc angle 11 design avoids the operator from being injured due to accidentally touching the sharp edge, thus improving the safety and humanization of the equipment.

[0037] The working principle and usage process of this utility model are as follows: In use, the entire device is designed around the support roller 1 to improve its wear resistance and facilitate parts replacement. The wear-resistant mechanism is achieved through semi-circular rings 2 movably connected to the front and rear sides of the support roller 1. High-chromium alloy wear-resistant rings 4 are fixed to the extended rings 3 on the surface of the semi-circular rings 2. Utilizing the wear-resistant properties of high-chromium alloy, the wear-resistant rings 4 effectively resist wear and extend the service life of the support roller 1 when it rubs against the track or other contact parts during operation. In the anti-detachment mechanism, an arc-shaped ring 5 movably connected to the surface of the semi-circular ring 2 is fixed to the support roller 1 surface by bolts 6 on the outer surface of the support roller 1. The toothed blocks 7 on the surface of the arc-shaped ring 5 interact with the track to prevent the track from detaching during the operation of the support roller 1. A protective ring 9 shields and protects the bolts 6, and the arc angle 11 prevents scratches to operators. This avoids the inconvenience caused by poor wear resistance and complicated maintenance of the excavator support roller 1, giving it the advantage of being easy to use.

[0038] In summary, in practical use, the wear-resistant mechanism and the anti-detachment mechanism of this invention work together. The wear-resistant mechanism, with its unique design and high-performance materials, significantly enhances the wear resistance of the support roller 1, effectively extending its service life. Simultaneously, the anti-detachment mechanism ensures the stable connection of related components, guaranteeing the stability of the overall structure. It is worth mentioning that the overall structure adopts a modular design concept. When external components, such as certain parts of the wear-resistant mechanism or the anti-detachment mechanism, become excessively worn or damaged, operators can quickly and conveniently replace and repair them without replacing the entire support roller 1. This modular design greatly simplifies the maintenance process, reduces maintenance costs and time, and makes it easy to use.
