Description

Technical Field

[0001] This utility model relates to the field of excavator equipment manufacturing technology, and more specifically to an excavator track protection device. Background Technology

[0002] Track shoes are chassis components of construction machinery, commonly used in excavators. They are continuous plate-like structures installed under the track frame, responsible for supporting the vehicle's weight and transmitting power. In existing technology, wear-resistant strips and track shoes are usually integrally molded, made of manganese steel, which has high strength and wear resistance, suitable for various complex working conditions, and can withstand a certain amount of external impact. However, when encountering hard ground, the wear-resistant strips are prone to wear due to "hard-on-hard" contact with the ground, and the excavator's movement is bumpy, causing discomfort to the operator and affecting operation. Therefore, in such conditions, the track shoes need simple protection to avoid wear and bumps. To address these problems, the inventor proposes an excavator track shoe protection device. By adding protective plates to the track shoes, with corresponding rubber strips on the protective plates, an effective cushioning effect is provided when the excavator travels on hard ground, preventing rapid wear of the wear-resistant strips and extending the service life of the track shoes.

[0003] To address the issue of short service life caused by wear and tear on the grounding ribs of track plates, especially on hard surfaces, Chinese patent (authorization announcement number: CN218594451U) discloses a wear-resistant, high-strength track plate structure. This utility model includes a main track plate plate, wear-resistant strips, and wear-resistant retaining strips. The top of the main track plate plate has multiple anti-slip protrusions, each with a detachable wear-resistant retaining strip. A lug is located on one side of the main track plate plate. The main track plate plate also has multiple mounting holes and waist holes. Wear-resistant strips are located on both sides of the top of the main track plate plate. This utility model enhances the wear resistance of the anti-slip protrusions by using anti-slip protrusions on the top of the main track plate plate and connecting them to wear-resistant retaining strips. These wear-resistant retaining strips strengthen the wear resistance of the anti-slip protrusions, giving the main track plate plate plate strong wear resistance and increasing its service life.

[0004] This solution still has some shortcomings in application. Since track shoes are typically made of manganese steel, which inherently possesses high strength and good wear resistance, the wear rate is relatively low on ordinary ground. However, on hard surfaces, the impact can easily cause wear. Furthermore, once wear occurs, replacement parts need to be easily replaceable to avoid cumbersome maintenance and increased time, thus reducing construction efficiency. Therefore, the structure of the track shoes needs to be improved to overcome the aforementioned limitations, making them more suitable for the requirements, more practical, providing better protection, and extending the service life of the track shoes. Utility Model Content

[0005] This utility model discloses an excavator track protection device, the main purpose of which is to overcome the above-mentioned deficiencies and shortcomings of the existing technology.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A protective device for excavator track plates includes a track plate body and a protective plate. The track plate body is integrally formed and has several grounding ribs on its outer surface. The protective plate is adapted to cover the outer side of the track plate body and is fixed by bolts. The middle section of the protective plate has several raised grooves corresponding to the grounding ribs. The bottom of the raised grooves is open, and the two ends of the inner side of the open structure are provided with locking grooves, which movably lock rubber strips.

[0008] Furthermore, the protective plate has a first bolt hole in the middle and second bolt holes on all four sides.

[0009] Furthermore, the left and right sides of the locking groove are open structures, and the rubber strip passes through the open structures into the locking groove.

[0010] Furthermore, the card slot has arc-shaped grooves on both sides, and the rubber strip has corresponding hanging ears on both sides, which are adapted to be embedded in the arc-shaped grooves.

[0011] Furthermore, the locking groove is provided with a plurality of limiting protrusions, and the rubber strip is provided with corresponding limiting grooves, which are movably locked with the limiting protrusions.

[0012] Furthermore, the rubber strip has a frustum structure that is wider at the bottom and narrower at the top, and the top of the frustum structure is provided with several rubber protrusions.

[0013] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0014] This invention firstly adds protective plates to the outer side of the track plate body, with each protective plate individually corresponding to each track plate body, facilitating installation and replacement. Next, the protective plates have several raised grooves that correspond to the grounding ribs of the track plate body. Rubber strips are installed at the bottom of the raised grooves, with an outward-protruding structure. These rubber strips act as a buffer and shock absorber between the ground and the grounding ribs, preventing the grounding ribs from colliding with the hard ground and causing rapid wear, thus extending the service life of the track plate body. Simultaneously, the rubber strips also have an anti-slip function, increasing traction as the grounding ribs are prone to slipping on hard surfaces. Finally, the rubber strips can be pushed in and pushed out from the arc-shaped grooves on both sides of the embedded grooves, allowing for quick replacement when wear occurs without removing the protective plates. This invention features a novel structure and ingenious design, effectively preventing track plates from scrambling and wearing out on hard surfaces, and providing effective shock absorption and anti-slip properties, making it suitable for widespread application.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, an excavator track plate protection device includes a track plate body 1 and a protective plate 2. The track plate body 1 is an integrally formed structure and has several grounding ribs 3 on its outer surface. The protective plate 2 is adapted to cover the outer side of the track plate body 1 and is fixed by bolts. The middle section of the protective plate 2 is provided with several raised grooves 4, which are correspondingly sleeved with the grounding ribs 3. The bottom of the raised grooves 4 is an open structure, and the two ends of the inner side of the open structure are provided with locking grooves 5, which movably lock rubber strips 6.

[0021] Furthermore, the protective plate 2 has a first bolt hole 21 in the middle and second bolt holes 22 on all four sides.

[0022] Furthermore, the left and right sides of the locking groove 5 are open structures, and the rubber strip 6 passes through the open structures into the locking groove 5.

[0023] Furthermore, the locking groove 5 is provided with arc-shaped grooves 51 on both sides, and the rubber strip 6 is provided with corresponding hanging ears 61 on both sides, which are adapted to be embedded in the arc-shaped grooves 51.

[0024] Furthermore, the locking groove 5 is provided with a plurality of limiting protrusions 52, and the rubber strip 6 is provided with a corresponding limiting groove (not shown in the schematic diagram due to viewing angle), which is movably locked with the limiting protrusions 52.

[0025] Furthermore, the rubber strip 6 has a frustum structure that is wider at the bottom and narrower at the top, and the top of the frustum structure is provided with several rubber protrusions 7.

[0026] Example: First, several rubber strips 6 are inserted into the locking groove 5 through the open structures on both sides of the locking groove 5 and locked into the arc groove 51 through the lugs 61, so that the lower part of the rubber strip 6 is fastened into the locking groove 5. At the same time, the limiting groove of the rubber strip 6 is also embedded into the limiting protrusion 52, so that the rubber strip 6 is further fastened into the locking groove 5. The upper part of the rubber strip 6 protrudes outward. Next, the protective plate 2 is installed on the outside of the track plate body 1 and fixed through the first bolt hole 21 and the second bolt hole 22. At this time, the rubber strip 6 is on the outside of the grounding rib 3. When the excavator encounters hard ground, the rubber strip 6 plays an effective buffering role, avoiding hard collisions that cause wear to the grounding rib 3. At the same time, the rubber strip 6 can also increase the grip effect, effectively preventing slippage and avoiding slippage when the excavator is moving. Finally, when the rubber strip 6 wears out after a period of use, the rubber strip 6 can be pulled out from the locking groove 5 and a new rubber strip 6 can be inserted into the locking groove 5 again. Replacement is very convenient, and it is not even necessary to remove the protective plate 2.

[0027] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0028] This invention firstly adds protective plates to the outer side of the track plate body, with each protective plate individually corresponding to each track plate body, facilitating installation and replacement. Next, the protective plates have several raised grooves that correspond to the grounding ribs of the track plate body. Rubber strips are installed at the bottom of the raised grooves, with an outward-protruding structure. These rubber strips act as a buffer and shock absorber between the ground and the grounding ribs, preventing the grounding ribs from colliding with the hard ground and causing rapid wear, thus extending the service life of the track plate body. Simultaneously, the rubber strips also have an anti-slip function, increasing traction as the grounding ribs are prone to slipping on hard surfaces. Finally, the rubber strips can be pushed in and pushed out from the arc-shaped grooves on both sides of the embedded grooves, allowing for quick replacement when wear occurs without removing the protective plates. This invention features a novel structure and ingenious design, effectively preventing track plates from scrambling and wearing out on hard surfaces, and providing effective shock absorption and anti-slip properties, making it suitable for widespread application.

[0029] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
