[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The chain rail sealing mechanism of the crawler transporter comprises a chain 1, a connecting block 2, a fixed block, a pin 4, a sealing block 5, a cylinder 6 and a limiting mechanism 7, wherein the chain 1 is arranged on the connecting block 2, the fixed block is connected to the chain 1 through the pin 4, the sealing block 5 is connected to the connecting block 2 through the cylinder 6, one end of the cylinder 6 passes through the connecting block 2 and the sealing block 5 in sequence, the limiting mechanism 7 comprises a bearing 8, a rotating block 9, a groove 10, a spring 11, a long plate 12, a clamping block 13 and a pressing block 14, the bearing 8 is arranged on the connecting block 2, and the fixing block is connected to the chain 1 through the pin 4. On the connecting block 2, one end of the rotating block 9 is rotatably connected to the bearing 8, and the other end of the rotating block 9 abuts against the cylinder 6. The groove 10 is opened on the cylinder 6. One end of the spring 11 is connected to the inner wall of the groove 10, and the other end of the spring 11 is connected to one end of the long plate 12. One end of the clamping block 13 is connected to the other end of the long plate 12, and the other end of the clamping block 13 passes through the groove 10 and extends into the rotating block 9.
