Multifunctional all-terrain walking type hydraulic excavator

Abstract

The invention provides a multifunctional all-terrain walking type hydraulic excavator which comprises a multifunctional working device, a cab, a revolving platform assembly, a pivoting support, a walking type chassis and the like. The multifunctional all-terrain walking type hydraulic excavator can quickly replace various hydraulic tools such as a bucket, a grab bucket and a quartering hammer through a quick-replacing device, can be connected with various hydraulic tools such as a hydraulic drilling rig and a hydraulic vibration shovel through a hydraulic quick coupling, and can carry out self rescue, traction rescue and the like through a hydraulic capstan which is mounted at the front end of the walking type chassis. The walking type chassis can be adapted to terrains by adjusting the pendulum angle of a front walking leg and a rear walking leg, and can walk and operate on complex terrains like a mountainous region, a marsh and an abrupt slope. The multifunctional all-terrain walking type hydraulic excavator has the advantages of being simple in structure and convenient to operate and well solves the flexible problem of mechanical equipment under the complex terrains.

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.

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
