Amphibious hydraulic excavator sealing box type caterpillar band assembly

Abstract

The invention discloses an amphibious hydraulic excavator sealing box type caterpillar band assembly which comprises a plurality of rolling wheel caterpillar track assemblies which are connected in series to form a ring. Each rolling wheel caterpillar track assembly comprises a track shoe, a rolling wheel caterpillar track section and a detachable mud scraping plate assembly; the track shoe is mounted on the outer surface of the rolling wheel caterpillar track section through bolts; and the detachable mud scraping plate assembly is mounted on the inner surface of the rolling wheel caterpillartrack section. The amphibious hydraulic excavator sealing box type caterpillar band assembly is convenient to disassemble and maintain, the buoyancy is improved, silt is removed in real time, abrasionis small, and the internal structural layout of the rolling wheel caterpillar track sections is optimized and improved.

Description

technical field [0001] The invention relates to the technical field of excavator pontoon chain rails, in particular to a sealed box-type track assembly of an amphibious hydraulic excavator. Background technique [0002] The structure of the amphibious hydraulic excavator is mainly divided into an upper body and a floating box crawler lower body. The pontoon crawler-type lower car body adopts a multi-hull boat-shaped frame-type pontoon structure, a middle platform, and a sealed box-type crawler assembly. Driven by the driving force of the motor, relative motion is generated relative to the left and right pontoons, thereby realizing the walking and floating of the left and right pontoons of the amphibious hydraulic excavator. [0003] Due to the complex and harsh working environment of the amphibious hydraulic excavator, it is easy to accelerate the damage and corrosion of the crawler assembly. The amphibious hydraulic excavator is mainly driven and operated in the muddy land...

AI Technical Summary

Problems solved by technology

[0003] Due to the complex and harsh working environment of the amphibious hydraulic excavator, it is easy to accelerate the damage and corrosion of the crawler assembly. The amphibious hydraulic excavator is mainly driven and operated in the muddy land with low bearing capacity, and the gravel in the muddy water is relatively hard and sharp. The track shoes in the track assembly are greatly damaged; muddy water and mud sand accumulate on the upper part of the left and right pontoons, which can easily cause the movement of the track to be blocked. As the resistance increases, the track will be damaged faster and the upper surface of the pontoon will be damaged.

[0004] The traditional track assembly is divided into two parts: sealed track tiles and roller chains. These two parts are integral welded parts and cannot be separated separately. It is impossible to repair and replace a single damaged sealed track tile and roller chain link.
