Multi-functional walking excavator

Abstract

The invention provides a multi-functional walking excavator, and relates to the technical field of excavator technology. An interlinked suspension system of the multi-functional walking excavator comprises hydraulic jackings, a left-right balance control device, a front-back balance control device, a first steering gear, a second steering gear, a fluid pump and a fluid source; the hydraulic jackings are arranged on the upper sides of vehicle wheels of the excavator vehicle, two hydraulic jackings are arranged on the upper side of each vehicle wheel, the two hydraulic jackings, located at a same end, on different vehicle wheels, are connected with each other through first pipelines, and the rest of the hydraulic jackings, located at the same end, on different vehicle wheels are connected with the rest of the hydraulic jackings, located at the other end of a same side while on different vehicle wheels through second pipelines; and the left-right balance control device is connected with the second pipelines which are located on two sides of the vehicle through pipelines correspondingly, and the front-back balance control device are connected with the first pipelines located on two sides of the vehicle through the pipelines correspondingly. The multi-functional walking excavator rarely bumps on rough ground, is sensitive to response, good in stability and comfort performance, has the functions of anti-side-tipping, anti-side-rollover, and anti-pitching, and is high in climbing performance.

Description

[0001] Technical field: [0002] The invention relates to the technical field of excavators, in particular to a walking excavator with multiple functions. [0003] Background technique: [0004] The walking all-terrain excavator is the extension and supplement of the function of the crawler excavator. The crawler excavator has strong power, a wide range of use and a high market share. It is the most widely used excavator. However, due to the limitations of the structure of crawler excavators, it is impossible to work safely and efficiently on complex terrain such as rugged or steep or muddy or tall obstacles, and can only rely on manual work. Walking excavators often work in the wild with complex and uneven terrain, especially when climbing hills and uneven slopes or stepped terrains. Its hydraulic suspension is not flexible enough, which limits the speed of the excavator, and often requires a lot of work. Only slow can avoid bumps or excessive tilting, long-distance migration...

Problems solved by technology

However, due to the limitation of the structure of crawler excavators, it is impossible to work safely and efficiently on complex terrain such as rugged or steep or muddy or tall obstacles, and can only rely on manual work.

Walking excavators often work in the wild with complex and uneven terrain, especially when climbing hills and uneven slopes or stepped terrains. Its hydraulic suspension is not flexible enough, which limits the speed of the excavator, and often requires a lot of work. Only slow can avoid bumps or excessive tilting, long-distance migration on uneven ground cannot be driven quickly, and a lot of time is wasted when stopping to work on uneven terrain to adjust the balance of the fuselage, which greatly reduces the work of the excavator. Efficiency and safety performance
