Abstract

The invention discloses a swing support leg mounting structure which comprises a swing support leg, a machine body and a stretchable driving device. One end of the swing support leg is hinged to the machine body. The stretchable driving device is hinged to the swing support leg and the machine body. The stretchable driving device comprises a first driving cylinder (3) and a second driving cylinder (4). One of the first driving cylinder (3) and the second driving cylinder (4) is hinged to the machine body, and the other one of the first driving cylinder (3) and the second driving cylinder (4) is hinged to the swing support leg. When the first driving cylinder (3) and the second driving cylinder (4) completely retract, the swing support leg is in a retraction state. When the first driving cylinder (3) and the second driving cylinder (4) completely stretch out, the swing support leg is in a stretching state. When one of the first driving cylinder (3) and the second driving cylinder (4) completely stretches out and the other one of the first driving cylinder (3) and the second driving cylinder (4) completely retracts, the swing support leg is in the position where the swing support leg rotates a preset angle from the machine body. In addition, the invention further discloses a hydraulic control device, a control system, and an engineering machinery and swing support leg coordination control method.

Description

technical field [0001] The invention relates to an installation structure of a swing outrigger. In addition, the invention also relates to a hydraulic control device, a control system, an engineering machine and a method for cooperating with the swing outrigger. Background technique [0002] Construction machinery such as concrete pump trucks usually need to use support devices to realize the support during work, so as to enhance the stability during work and avoid overturning caused by excessive work load. The supporting device generally includes two pairs of outriggers at the front and back, and each outrigger has two positions of retracting and supporting. When moving, the outriggers need to be retracted; during construction, the outriggers need to be unfolded to achieve support. [0003] In the prior art, outrigger-type construction machinery is divided into two categories according to the position when it is stowed: one is a swing-type outrigger, and the stowed positio...
