[0002] High-strength alloy steel tracks are tracks specifically designed to improve mechanical performance and extend service life. They are commonly used in heavy-duty construction machinery, such as rotary drilling rigs and excavators, and can cope with complex and harsh working environments. Chinese utility model patent CN208149472U discloses a track, including a base plate and track plates. The base plate has upper and lower hinge ends on opposite sides, with two upper and two lower hinge ends each. The two upper hinge ends are located between the two lower hinge ends and are equidistant from each other. The base plate has a mounting groove on its surface, and the track plates are disposed within the mounting groove. Each track plate has a baffle on opposite sides outside the mounting groove, with one side of the baffle abutting one end of the base plate. The baffle is connected to the base plate by fasteners, and the upper surface of the track plate is higher than the upper surface of the base plate. This utility model features a reasonable structural design and convenient assembly / disassembly. Based on existing solutions and actual production and processing, existing high-strength alloy steel tracks can disperse stress through unloading holes, i.e. stress dispersion holes, but it is inconvenient to increase the contact area with the ground when dispersing stress. Therefore, we propose a high-strength alloy steel track with an anti-fatigue stress dispersion structure to solve the problems mentioned above. Utility Model Content

[0014] Please see Figures 1-5 Existing high-strength alloy steel tracks can disperse stress through unloading holes, i.e. stress dispersion holes, but it is inconvenient to increase the contact area with the ground when dispersing stress.

A high-strength alloy steel track with a fatigue stress dispersion structure includes a chain 1, an alloy steel track plate 2, dispersion holes 3, reinforcing ribs 4, screw holes 5, rubber pads 6, and screws 7. Alloy steel track plates 2 are installed on the outer side of the chain 1. A reinforcing rib 4 is integrally fixed on the lower surface of the alloy steel track plate 2, and a screw hole 5 is opened inside the reinforcing rib 4. A screw hole 5 is opened inside the chain 1. The alloy steel track plate 2 is connected to the chain 1 by screws 7. By removing the screws 7, it is easy to disassemble and assemble the alloy steel track plate 2 and the chain 1, and it is easy to replace the alloy steel track plate 2 separately. like Figure 2 , Figure 4 and Figure 5 As shown, the alloy steel track plate 2 has a dispersion hole 3 inside, and a rubber pad 6 is attached to the inside of the dispersion hole 3. The depth of the dispersion hole 3 is equal to half the height of the rubber pad 6, and the outer side of the rubber pad 6 is flush with the outer side of the alloy steel track plate 2. The setting of the dispersion hole 3 can disperse the stress on the alloy steel track plate 2, so that the track has a fatigue stress dispersion structure. The rubber pad 6 protects the dispersion hole 3 to prevent sand and mud from entering the interior of the dispersion hole 3. When the alloy steel track plate 2 touches the ground, the rubber pad 6 contacts the ground, increasing the contact area between the track and the ground and improving stability.
