Specific embodiment
Referring to attached drawing, a kind of hydraulic suction dredge crawler belt and is located at 10 two sides of creeper tread at creeper tread 10 including wedge shaped strip
Rail chain structure 20, the creeper tread 10 perpendicular to rail chain structure 20 outer rolling face arrange；
The rail chain structure 20 includes the outer plate 21 and inner plate 22 of successively hinge arrangement, between two sides inner plate 22
It is disposed with guide 28, idler wheel 26 is equipped on guide 28, the both ends of guide 28 are protruded into the hinge hole of inner plate 22, guide 28
Inner hole places rail chain pin 29, and the outer end of the rail chain pin 29 is placed in the outside of outer plate 21, and the outer end of rail chain pin 29 passes through
Round nut is fixed, and is provided with first seal 23 between the outer plate 21 and inner plate 22, and first seal 23 is located at
It is close to rail chain pin 29 and arranges in the end of guide 28；Second seal 24 and third are set between the inner plate 22 and idler wheel 26
Sealing element 25, the second seal 24 are close to guide 28 and are arranged, the third sealing element 25 is close to idler wheel 26 and is arranged；Rolling
The radial direction of wheel 26 offers oil filler 27, and the oil filler 27 extends inwardly to the gap location between idler wheel 26 and guide 28,
The radial direction of guide 28 offers logical hydraulic fluid port, and the logical hydraulic fluid port extends inwardly at rail chain pin 29；
The creeper tread 10 is located at the evacuation position of idler wheel 26, and the outer end face of creeper tread 10 is higher than the top surface of idler wheel 26；
The buoyancy tank rail contact of the idler wheel 26 and hydraulic suction dredge, the idler wheel 26 are rolled along buoyancy tank track and are moved ahead.
