Abstract

The invention discloses a swinging supporting leg mounting structure which comprises a swinging supporting leg, a machine body and a telescopic driving device. One end of the swinging supporting leg is hinged to the machine body. The telescopic driving device is hinged to the swinging supporting leg and the machine body. The telescopic 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 is hinged to the swinging supporting leg. When the first driving cylinder (3) and the second driving cylinder (4) are retracted completely, the swinging supporting leg is in a withdrawing position. When the first driving cylinder (3) and the second driving cylinder (4) extend out completely, the swinging supporting leg is in a stretching position. When one of the first driving cylinder (3) and the second driving cylinder (4) extends out completely and the other one is in a complete-retracted state, the swinging supporting leg is in a machine-body-rotating-preset-angle position. In addition, the invention discloses matching control method of a hydraulic control device, a control system, engineering machinery and the swinging supporting leg.

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...
