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.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example 1:

[0024] Please see Figure 1 As shown, this utility model provides a connection structure that facilitates the replacement of excavator tracks, including a first track section 1 and a second track section 2. Both the connecting ends of the first track section 1 and the second track section 2 are equipped with connecting seats 3. The connecting seats 3 have an installation cavity 4 inside. Fixed seats 8 are fixedly installed at both the front and rear ends of the connecting seats 3. A positioning vertical plate 9 is vertically snapped into the inside of the fixed seat 8. An auxiliary reinforcing plate 10 is welded to the upper end of the positioning vertical plate 9. The inner end of the auxiliary reinforcing plate 10 extends to the top of the connection part of the first track section 1 and the second track section 2 and is connected by fastening bolts 11.

[0025] This technical solution, through the design of the mounting cavity 4, facilitates workers to quickly locate and operate the connecting components, avoiding the cumbersome process of finding and operating connecting components in traditional structures, thus saving replacement time. The positioning vertical plate 9, which is vertically snapped into place inside the fixing seat 8, plays a precise positioning role when the first track section 1 and the second track section 2 are connected. During track installation, the positioning vertical plate 9 can guide the two track sections to be accurately aligned, avoiding problems such as loose connection or abnormal track operation caused by installation position deviation. During the excavator's operation, the track will be subjected to various forces, and the positioning vertical plate 9 can withstand some of the lateral and longitudinal forces, ensuring a tight connection between the track sections and reducing the risk of track loosening or even falling off.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, limiting seats 5 are fixedly installed on both sides of the inner cavity of the mounting cavity 4. Protrusions are fixedly installed at the bottom of the connecting ends of the first track section 1 and the second track section 2, and the lower ends of the protrusions are engaged with the inside of the mounting cavity 4 and fit against the side of the limiting seats 5. Connecting frames 6 are installed at the bottom of the connection between the first track section 1 and the second track section 2. The middle part of the connecting frame 6 is engaged with the outside of the connecting seat 3, and the ends are connected to the bottom of the first track section 1 and the second track section 2 respectively by connecting bolts 7.

[0028] Adopting such Figure 1 The technical solution shown has a limiting seat 5 on both sides of the mounting cavity 4 that cooperates with the protrusion at the bottom of the track section connection end. This provides precise positioning when the track sections are connected, avoiding the installation difficulties and weak connections caused by inaccurate positioning in traditional connection methods. The limiting seat 5 effectively prevents the track section from shifting in the lateral direction by limiting the protrusion. During the operation of the excavator, the track will be subjected to various lateral forces, such as the lateral force when turning. The tight fit between the limiting seat 5 and the protrusion can withstand these lateral forces, ensuring the stable connection between the track sections and reducing the risk of track loosening and wear.

[0029] Secondly, in the technical solution, positioning plates 12 are symmetrically installed on the outside of the fixed base 8. A snap-fit ​​plate is fixedly installed on one side of the positioning plate 12, and the inner end of the snap-fit ​​plate is snapped into the inside of the positioning vertical plate 9. The end of the positioning plate 12 is connected by bolts. A vertical slot adapted to the positioning vertical plate 9 is opened inside the fixed base 8, and elastic rubber pads are provided on both sides of the vertical slot.

[0030] Its adoption is as follows Figure 1 The technical solution shown is that the positioning plate 12 is snapped into the interior of the positioning vertical plate 9 by a snap-fit ​​plate on one side, and the end of the positioning plate 12 is then connected with bolts, which further strengthens the connection between the positioning vertical plate 9 and the fixed seat 8. When the excavator is working, the tracks will be subjected to complex and variable forces. This additional reinforcement method can effectively prevent the positioning vertical plate 9 from shaking and shifting in the fixed seat 8.

[0031] Example 3:

[0032] This utility model is as follows Figures 1-5 As shown, the inner end of the auxiliary reinforcing plate 10 is provided with a threaded hole that is compatible with the fastening bolt 11, and the inner surface of the threaded hole is polished; the connecting seat 3 is made of high-strength alloy steel and its surface is treated with anti-corrosion; the lower end of the positioning vertical plate 9 is provided with a chamfer, and an insertion groove that is compatible with the inner snap-fit ​​plate of the positioning card plate 12 is provided inside the positioning vertical plate 9.

[0033] By adopting the above technical solution, the inner end of the auxiliary reinforcing plate 10 is provided with a threaded hole that matches the fastening bolt 11, which can ensure that the fastening bolt 11 and the auxiliary reinforcing plate 10 are tightly connected. When the auxiliary reinforcing plate 10 is fixed above the connection between the first track section 1 and the second track section 2 by the fastening bolt 11, this matching threaded connection can provide sufficient preload, effectively preventing the bolts from loosening due to vibration and other factors during excavator operation, ensuring that the auxiliary reinforcing plate 10 continues to play a reinforcing role, and improving the overall stability of the track connection.

[0034] The working principle of this utility model is as follows: When it is necessary to connect the first track link 1 and the second track link 2, firstly, the protrusions at the bottom of the connecting ends of the first track link 1 and the second track link 2 are respectively inserted into the corresponding mounting cavities 4 of the connecting seat 3. The limiting seats 5 on both sides of the mounting cavity 4 will limit the protrusions, so that the protrusions fit against the sides of the limiting seats 5, achieving preliminary accurate positioning of the first track link 1 and the second track link 2 in the horizontal direction. Then, the middle part of the connecting frame 6 is engaged with the outside of the connecting seat 3. Then, the connecting bolts 7 are used to connect the end of the connecting frame 6 to the bottom of the first track link 1 and the second track link 2. In this way, the connecting frame 6 serves as a connection between the first track link 1 and the second track link 2. The bottom of the connection part provides reinforcement. The positioning vertical plate 9 is vertically inserted into the vertical slot inside the fixed base 8. After the positioning vertical plate 9 is installed, the auxiliary reinforcement plate 10 welded to its upper end will extend to the top of the connection part of the first track section 1 and the second track section 2. By screwing the fastening bolt 11 into the threaded hole at the inner end of the auxiliary reinforcement plate 10, the connection part of the first track section 1 and the second track section 2 is further reinforced, enhancing the reliability of the connection. Finally, the positioning plate 12 is installed on the outside of the fixed base 8, so that the positioning plate 12 fits against the snap-fit ​​plate on one side of the fixed base 8 and snaps into the insertion slot inside the positioning vertical plate 9. Then, the end of the positioning plate 12 is connected with bolts.
