The invention provides an engineering vehicle and a landing leg device and a landing leg assembly of the engineering vehicle. The landing leg device of the engineering vehicle comprises a landing leg beam, the landing leg assembly and a landing leg oil cylinder. The landing leg assembly comprises a landing leg bottom plate and a pressure sensor arranged on the landing leg bottom plate. The landing leg oil cylinder comprises a cylinder body and a piston rod which are matched with each other. The upper end of the cylinder body is connected with the landing leg beam, the lower end of the piston rod abuts against the top of the pressure sensor and enables the landing leg pressure to be exerted on the pressure sensor, and the pressure sensor measures the landing leg pressure. The landing leg device of the engineering vehicle is simple in structure and high in measuring precision.
Description
technical field [0001] The invention relates to the technical field of engineering vehicle auxiliary support, in particular to an engineering vehicle and its outrigger device and outrigger assembly. Background technique [0002] Due to the large working load of engineering vehicles, most of them support the entire vehicle body through legs, and the wheels are out of contact with the ground. Such engineering vehicles include concrete pump trucks, fire ladders and cranes, etc. The safety performance of engineering vehicles during operation is increasingly being affected People are concerned that the European Union even regards the stability test of such engineering vehicles as the entry threshold for entering various EU countries. [0003] Engineering vehicles often have rollover accidents during operation due to the following reasons: 1. The weight of the vehicle cannot be supported due to problems such as weak foundation bearing capacity, foundation collapse, or encountering...
