Abstract

The invention discloses a supporting system of an engineering machine, which comprises a first supporting leg, a second supporting leg, a third supporting leg and a fourth supporting leg which are arranged on the engineering machine. Additional supporting legs are arranged between the third supporting leg and the fourth supporting leg, and the minimum distance from a ligature of a supporting point of the third supporting leg and a supporting point of the fourth supporting leg to the circumference of a gravity center circle of the engineering machine is shorter than the minimum distance from a ligature of supporting points of each two adjacent of the third supporting leg, the fourth supporting leg and the additional supporting legs to the circumference of the gravity center circle of the engineering machine. By the aid of the additional supporting legs, anti-tipping capacity and supporting capacity of a whole vehicle are improved, and when being shortened, the supporting legs do not need to occupy sites with large site and can keep stability as same as those in the prior art, so that the engineering machine with the supporting system can be operated in limited space and meet construction needs of the narrow sites, and the application range of the engineering machine is widened. The invention further discloses the engineering machine comprising the supporting system.

Description

technical field

[0001] The invention relates to the technical field of engineering machinery, in particular to a support system. The invention also relates to a construction machine with a support system as described above. Background technique

[0002] Construction machinery usually has a support system to support the entire vehicle and drive the entire vehicle. Taking a concrete pump truck as an example, its support system generally includes four outriggers located on a fixed turret. During operation, two outriggers protrude forward and the other two outriggers protrude backward.

[0003] Please refer to figure 1 , figure 1 It is a schematic diagram of the distribution of outriggers of a concrete pump truck in the prior art, and the figure also shows the relationship between the polygon formed by the support points of the outriggers and the stability of the vehicle body.

[0004] The support system of the concrete pump truck is provided with a first front outrigger 11 ...
