Description

Technical Field

[0001] This utility model relates to the field of engineering equipment accessories technology, and in particular to an excavator track plate with anti-slip teeth. Background Technology

[0002] Excavator track shoes are key components of the construction machinery chassis, primarily supporting the weight of the equipment, transmitting driving force, and adapting to complex terrain. Classified by ground contact shape: single-ribbed track shoes offer strong traction and are suitable for bulldozers and tractors; triple-ribbed track shoes balance adhesion and bending strength, and are the mainstream choice for excavators; flat-bottomed track shoes are mostly used in swamps or farmland to reduce ground pressure and turning resistance. Special terrain adaptations: Swampy operations require extra-wide track shoes (over 800 mm wide) or extended tracks to increase the contact area and reduce ground pressure; triangular track shoes are specifically designed for soft ground, compressing the soil to increase surface density and enhance adhesion.

[0003] Currently, while excavator track shoes are equipped with raised strips on their surface to provide anti-slip functionality, the height and shape of these strips may not be optimally designed. This can result in insufficient friction to prevent track slippage under certain terrain or working conditions, such as wet, muddy, or soft ground. Furthermore, these raised strips are prone to wear after prolonged use, further reducing their anti-slip performance. Additionally, different working environments require different materials and hardness for the raised strips; inappropriate material selection or insufficient hardness can also negatively impact the anti-slip effect. Utility Model Content

[0004] The purpose of this utility model is to provide an excavator track plate with anti-slip teeth, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An excavator track pad with anti-slip teeth includes a first modified track pad, a second modified track pad connected to the first modified track pad, a third modified track pad connected to the second modified track pad, and multiple first modified track pads, second modified track pads and third modified track pads connected together to form an excavator track;

[0007] The first modified track plate includes an L-shaped main plate, a protrusion, a track plate pivot, and a docking part. The protrusion and the docking part are respectively located at the front and rear ends of the L-shaped main plate. The side wall opening of the protrusion is inserted into the track plate pivot. A notch is provided between the two protrusions for the insertion of the docking part of the next-level modified track plate. A docking groove is provided between the two docking parts for the insertion of the protrusion of the next-level modified track plate. A through hole is provided in the docking groove for the insertion of the track plate pivot.

[0008] The upper end of the L-shaped main board has a recessed groove. A limiting rod is inserted into the side wall of the L-shaped main board. The limiting rod passes through multiple recessed grooves and is connected to anti-slip protruding teeth installed in the recessed grooves. The two ends of the limiting rod are fastened to the L-shaped main board by double nut fasteners.

[0009] As a further preferred embodiment of this utility model, a plurality of the protrusions are equidistantly distributed at the front end of the L-shaped main board, and the protrusions and the L-shaped main board are designed as a single unit. The outer end of the protrusion is designed in an arc shape, and the round hole is placed at the center of the end face of the protrusion to facilitate the insertion of the track plate shaft.

[0010] As a further preferred embodiment of this utility model, a plurality of the docking parts are equidistantly distributed at the lower rear end of the L-shaped motherboard. The docking parts are integrated with the L-shaped motherboard. The outer end of the docking part is arc-shaped, and the round hole on the protrusion is directly opposite the through hole.

[0011] As a further preferred embodiment of this utility model, the first modified track plate, the second modified track plate, and the third modified track plate have the same structure and are connected by a track plate pivot.

[0012] As a further preferred embodiment of this utility model, a plurality of the recessed grooves are equidistantly distributed on the L-shaped main board, the edges of the recessed grooves are arc-shaped, the inner ends of the recessed grooves are arc-shaped, and the double nut fastener includes a double nut and an anti-slip washer, the anti-slip washer is placed between the double nut and the L-shaped main board, and is fixed on the L-shaped main board by the double nut fastener.

[0013] As a further preferred embodiment of this utility model, the anti-slip protruding teeth are designed in a cubic shape. The anti-slip protruding teeth rotate along the limiting rod in the recessed groove, and the anti-slip protruding teeth protrude accordingly, thereby improving the anti-slip effect.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Through the precise design of the protrusions and mating parts, and the aligned fit between the track plate pivot and the perforation, a precise and stable connection between the various modified track plates is achieved, ensuring the integrity and stability of the track system. The protrusions and L-shaped main plates, as well as the mating parts and L-shaped main plates, are all designed as an integrated unit, which enhances the strength and durability of the structure and reduces wear and failure risk at the connection points. The equidistantly distributed protrusions and mating parts, as well as the arc-shaped holes and perforations, make the connection process smoother and improve assembly efficiency.

[0016] The anti-slip protruding teeth adopt a cubic design and can rotate freely in the recessed groove along the limiting rod. When rotated to a specific position, they can protrude, effectively improving the anti-slip effect of the track shoes. This design enables the excavator to maintain stable operation in various complex terrains, enhancing the excavator's adaptability and safety. The limiting rod is firmly installed on the L-shaped main plate with double nut fasteners, ensuring the stability and reliability of the anti-slip protruding teeth.

[0017] The modified track shoe connection system provides a stable foundation for the anti-slip protruding tooth mechanism, enabling the anti-slip protruding teeth to function effectively in various terrains. The protruding design of the anti-slip protruding tooth mechanism further enhances the friction between the track shoes and the ground, and together with the modified track shoe connection system, ensures the excavator's stability and passability in complex terrains. The two work together to improve the overall performance and work efficiency of the excavator, and reduce the failure rate and maintenance costs. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 - Figure 4 As shown, this utility model provides an excavator track plate with anti-slip teeth. The track plate is composed of multiple modified track plates connected in an orderly manner, specifically including a first modified track plate 1, a second modified track plate 2, and a third modified track plate 3. These modified track plates are interconnected through a specific connection method to jointly form the complete track system of the excavator.

[0025] The first modified track plate 1 mainly consists of an L-shaped main plate 11, a protrusion 12, a track plate pivot 14, and a docking part 15. The protrusion 12 and the docking part 15 are respectively located at the front and rear ends of the L-shaped main plate 11. The side wall of the protrusion 12 has holes for inserting the track plate pivot 14. A notch 13 is formed between two adjacent protrusions 12 for inserting the docking part 15 of the next-level modified track plate. Simultaneously, a docking groove 17 is formed between two docking parts 15, and this groove 17 has through holes 16 for inserting the track plate pivot 14.

[0026] The upper end of the L-shaped main board 11 is designed with a recessed groove 18. A limiting rod 4 is inserted into the side wall of the L-shaped main board 11. The limiting rod 4 passes through multiple recessed grooves 18 and is connected to anti-slip protruding teeth 5 installed in the recessed grooves 18. The two ends of the limiting rod 4 are fixed by double-nut fasteners 6. The fastener includes double nuts and anti-slip washers. The anti-slip washers are placed between the double nuts and the L-shaped main board 11, thereby firmly installing the limiting rod 4 on the L-shaped main board 11.

[0027] Multiple protrusions 12 are equidistantly distributed at the front end of the L-shaped main board 11, and the protrusions 12 and the L-shaped main board 11 are integrated into one piece. The outer end of the protrusion 12 is arc-shaped, and the circular hole is located at the center of the end face of the protrusion 12. This design facilitates the smooth insertion of the track plate shaft 14. Similarly, multiple mating parts 15 are equidistantly distributed at the lower rear end of the L-shaped main board 11. The mating parts 15 are also integrated into the L-shaped main board 11, and the outer end of the mating parts 15 is arc-shaped. Furthermore, the circular holes on the protrusions 12 are aligned with the through holes 16, ensuring the accuracy of the connection.

[0028] The first modified track plate 1, the second modified track plate 2, and the third modified track plate 3 are structurally identical, and they are effectively connected to each other through the track plate pivot 14. Multiple recessed grooves 18 are distributed equidistantly on the L-shaped main plate 11, and the edges and inner ends of the recessed grooves 18 are all designed with arcs, which increases the overall aesthetics and practicality.

[0029] The anti-slip protruding tooth 5 adopts a cubic design and can rotate freely in the recessed groove 18 along the limiting rod 4. When the anti-slip protruding tooth 5 rotates to a specific position, it can protrude accordingly, thereby effectively improving the anti-slip effect of the track shoes and ensuring the stable operation of the excavator in various complex terrains.

[0030] Prepare multiple first modified track plates 1, second modified track plates 2, and third modified track plates 3. For each first modified track plate 1, pass a limiting rod 4 through multiple recessed grooves 18 on the L-shaped main plate 11, and install anti-slip protrusions 5 in the recessed grooves 18 to connect with the limiting rod 4. Then, fix both ends of the limiting rod 4 with double-nut fasteners 6 (including double nuts and anti-slip washers, with the anti-slip washers placed between the double nuts and the L-shaped main plate 11). Next, insert the track plate pivot 14 into the hole on the side wall of the protrusion 12 of the first modified track plate 1. Then, insert the mating part 15 of the second modified track plate 2 into the notch 13 between adjacent protrusions 12 of the first modified track plate 1, while ensuring that the through hole 16 in the mating groove 17 of the second modified track plate 2 is aligned with the round hole on the protrusion 12 of the first modified track plate 1. Next, insert the track plate pivot 14 into the through hole 16, and connect multiple first modified track plates 1 and second modified track plates 2 in sequence. Similarly, using the same method as described above for connecting the first modified track plates 1 and second modified track plates 2, connect the third modified track plate 3 to the second modified track plate 2, thus forming the complete track system of the excavator.

[0031] The assembled excavator track shoes with anti-slip teeth are installed onto the excavator. During excavator operation, the track shoes rotate as the excavator moves. When encountering complex terrain requiring enhanced anti-slip performance, the anti-slip protrusions 5 come into play.

[0032] Because the anti-slip protruding teeth 5 are cubical in design and can rotate freely in the recessed groove 18 along the limiting rod 4, when an enhanced anti-slip effect is needed, an external force (such as the vibration of the excavator or a specific operating device) is applied to make the anti-slip protruding teeth 5 rotate around the limiting rod 4 in the recessed groove 18. When the anti-slip protruding teeth 5 rotate to a specific position, they will protrude, thereby effectively improving the anti-slip effect of the track shoes and ensuring the stable operation of the excavator in various complex terrains.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
