A multifunctional all-terrain walking hydraulic excavator

Abstract

A multifunctional all-terrain walking-type hydraulic excavator comprises a multifunctional working apparatus (2), a cab (3), a slew assembly (4), a slewing bearing (6), and a walking-type chassis (5). By means of a hydraulic winch (5.9) arranged at the forward end of the chassis (5), the excavator is able to perform self-rescue and towing assistance. The walking-type chassis (5) adapts to terrain through adjustments of the swing angles of the forward and rear feet (5.2, 5.4, 5.5, 5.6) and thus is able to walk and operate in difficult terrain.

Description

technical field [0001] The invention relates to an excavator, in particular to a multifunctional all-terrain walking hydraulic excavator. Background technique [0002] Under the influence of national policy guidance and technological progress, my country's construction machinery has shown a rapid development momentum in recent years, and product categories and series have become more complete. Excavators are one of the important categories, and they have also received faster and better results. develop. There are many types of excavators, which can be divided into crawler type, tire type and walking type according to the walking mode. Compared with tire type excavators, crawler type excavators have better climbing ability and better stability, but their driving speed It is not high, and the chassis of the other two adopt a fixed structure, which has limited terrain adaptability. It is helpless for places with complex terrain such as mountains and swamps, and cannot be driven...

AI Technical Summary

Problems solved by technology

There are many types of excavators, which can be divided into crawler type, tire type and walking type according to the walking mode. Compared with tire type excavators, crawler type excavators have better climbing ability and better stability, but their driving speed It is not high, and the chassis of the other two adopt a fixed structure, which has limited terrain adaptability. It is helpless for places with complex terrain such as mountains and swamps, and cannot be driven and operated in these areas. Poor function scalability

The existing walking excavator has poor function expansion ability; only two front wheels have steering function, and the two rear wheels do not have steering function, and its front wheel steering structure is relatively complicated, and the protection of the oil cylinder is poor; the four sides of the chassis The joints are different, and the production and processing technology is not good; the joint degree of freedom between the front claw and the outrigger is small, and the terrain adaptability and grip reliability are poor.

For other types of walking hydraulic excavators, the terrain adaptability of the excavator is still limited, and it uses ordinary working devices, the walking performance is low, and the function expansion ability is also poor
