Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] refer to figure 1 , figure 2 and image 3 , double-arm hand tire type rescue mechanical hydraulic system, the hydraulic system can drive the main arm of the two working arms up and down, the auxiliary arm up and down, the attachment up and down, wrist rotation, wrist swing and attribute Tool work, the main arm of the left working arm rotates and the main arm swings, the turntable rotates when getting on the car, the cab lifts, the bulldozing shovel and the "Y" outrigger retract when getting off the car. In addition, it can also drive the running mechanism of the off-car tires, and through switching between different control modes, three steering modes, such as front-wheel steering, four-wheel steering and crab steering, can be realized respectively.

[0015] In this embodiment, the first oil pump 1 supplies oil to all actions on the right working arm of the ...

Abstract

A dual-arm wheeled rescue machinery hydraulic system comprising a first oil pump (1), a second oil pump (2), and a third oil pump (3). An oil supply pipe of the first oil pump (2) is in communication with an upper car right working arm, a cab lifting / lowering oil cylinder (23), a lower car Y-shaped support leg oil cylinder (26), and a lower wheel travelling motor (31). An oil supply pipe of the second oil pump (2) is in communication with an upper car left working arm, an upper cart turntable rotary motor (6), and a lower car dozer blade oil cylinder (36). An oil supply pipe of the third oil pump (3) is in communication with a fully hydraulic steering gear (39), a front axle steering oil cylinder (33), a rear axle steering oil cylinder (27), and a cooling gear motor. The hydraulic system allows two arms to work in coordination, satisfies complex operation requirements, accelerates rescue speed, and shortens rescue time.

Description

technical field [0001] The invention relates to a construction machine hydraulic system, in particular to a dual-arm hand-wheel type rescue machine hydraulic system. Background technique [0002] In recent years, buildings, landslides, mountain collapses and burials caused by earthquakes, mudslides, fires, explosions, terrorist activities and major production accidents have always threatened the safety of people's lives and property. After the above-mentioned accidents, it is often necessary for large-scale rescue machinery to be able to rush to the scene for effective rescue at the first time. At the current rescue scene, because there is no rescue machinery available, the traditional manual rescue method is still used to save people's lives at the scene at the first time. Conventional construction machinery, such as excavators, cranes and loaders, are single-handed. The form of the arm can only play the role of cleaning up the ruins afterwards, and cannot meet the complex...
