[0002] Track shoes are an important component of crawler cranes. They are continuous plate-like structures installed under the crawler frame, responsible for supporting the vehicle's weight and transmitting power.

The bottom of the edge buffer block 10 is connected with a pressure column 11, and a buffer rubber sleeve 12 is installed at the inner bottom of the edge guide groove 4 corresponding to the pressure column 11. When the edge buffer block 10 drives the pressure column 11 to slide, the bottom of the pressure column 11 fits and connects to the inner side of the buffer rubber sleeve 12. Combined with the buffering effect of the pressure column 11 and the buffer rubber sleeve 12, the pressure is buffered, thereby reducing the pressure on the track shoe body 1;

[0029] Connecting plates 14 are adjustably mounted on the bottom of both sides of the track shoe body 1 , and a mounting hook 16 is connected to the middle end of the bottom of the connecting plate 14 .

[0030] The track shoe body 1 has a sliding groove 13 at the middle of the bottom of both sides. The top of the connecting plate 14 is connected to the sliding groove 13 by a slider 15. The slider 15 has an adjustment groove 17 inside.

[0031] The inner side of the adjusting groove 17 is embedded with a circular nut seat 18 which is slidably connected. The inner side of the circular nut seat 18 is connected with a locking screw 19 by threading. The connecting plate 14 and the slider 15 slide along the sliding groove 13, and the slider 15 slides along the locking screw 19 through the limiting guide groove 20 in the middle thereof, so that the connecting plate 14, the slider 15 and the mounting hook 16 are slidably connected to the bottom of the track shoe body 1 in a sliding connection manner. A limiting guide groove 20 is provided at the top middle end of the slider 15, and the locking screw 19 is placed in the limiting guide groove 20.

[0032] The working principle and use process of the utility model are as follows: in the actual application process of the high-strength pressure-resistant track shoe, first, when the track shoe body 1 is connected and installed, the track shoe body 1 is conveniently connected and installed through the connecting plate 14 and the installation hook 16 at the bottom of the track shoe body 1, and during the actual installation process of the installation hook 16, the connecting plate 14, the slider 15 and the installation hook 16 are conveniently slidably connected to the bottom of the track shoe body 1 through the sliding groove 13;

[0034] In the process of walking, the crawler structure composed of multiple track shoe bodies 1 can protect the track shoe body 1 through the edge protection rubber 2 and the resistance-increasing rubber 3 on the surface of the track shoe body 1, and can also increase the grip of the crawler track and improve its traveling efficiency. In addition, based on the central buffer block 9 and the edge buffer block 10, it is convenient to receive the pressure between the track shoe body 1 and the ground. In combination with the edge guide groove 4, the mounting groove 5, the bottom plate 6, the buffer spring 7 and the damper 8, when the track shoe body 1 is subjected to excessive pressure at a local position during the friction between the track shoe body 1 and the ground, the central buffer block 9 and the edge buffer block 10 can be used to transfer the pressure to the buffer spring 7 and the damper 8, thereby achieving buffering of the excessive pressure.

[0035] In addition, the pressure is further buffered by combining the buffering effect of the pressure column 11 and the buffer rubber sleeve 12, so as to reduce the pressure on the track shoe body 1 through a multi-step buffering and pressure reduction treatment method, thereby protecting it and improving its actual pressure resistance.
