Abstract

The invention discloses an engineering machine. The construction machine includes outriggers, a slewing mechanism, and a vehicle body, and further includes a power source and a switching mechanism, wherein the power source is arranged on the vehicle body; the switching mechanism is connected to the power source and can be switched to The power of the power source is transmitted to the leg or the slewing mechanism. The construction machine may further include a first gear, a second gear and a third gear. The invention only sets one set of driving system on the outrigger and the slewing mechanism, and has the advantages of compact structure, high utilization rate of the driving system, stable movement of the outrigger, wide deployment range and the like.

Description

technical field [0001] The invention mainly relates to the field of engineering machinery, in particular, to an engineering machinery including a support leg and a turning mechanism. Background technique [0002] Concrete pump trucks, cranes and other construction machinery are generally equipped with outriggers and slewing mechanisms. When the construction machine arrives at the work site, the outriggers are deployed and the car body is supported by the outriggers, which can stabilize the center of gravity of the vehicle during the operation, thereby avoiding the construction machine from tipping over. The main operating devices (such as the boom system and the conveying pipe or hook on the boom system) are generally arranged on the slewing mechanism, and the rotation of the slewing mechanism drives the operating device to work in different positions. [0003] Before operation, the outriggers need to be unfolded to a certain position, and the slewing mechanism can only per...
