Abstract

The invention provides a supporting structure and an engineering mechanism. The supporting structure comprises a supporting frame, a first supporting leg, a second supporting leg, a first hydraulic cylinder and a second hydraulic cylinder, wherein the supporting frame is connected with an engineering mechanism body; the first supporting leg and the second supporting leg are transversally crossed, one end of the first supporting leg is hinged with one end of the second supporting leg through a first pin roll installed on the supporting frame; one end of the first hydraulic cylinder is connected with the supporting frame, and the other end of the first hydraulic cylinder is connected with the first supporting leg; and one end of the second hydraulic cylinder is connected with the supporting frame, and the other end of the second hydraulic cylinder is connected with the second supporting leg. The supporting structure ensures that the supporting during working is more stable, the length of a mechanism body cannot be increased, and the supporting structure is simple and easy to layout.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a support structure and construction machinery. Background technique [0002] With the progress of society and the development of science and technology, construction machinery such as roadheaders and cranes play an increasingly important role in infrastructure construction. Taking the cantilever roadheader as an example, it is an efficient tunneling equipment that integrates cutting, loading, and transfer. It is widely used in transportation, tunnels, mining and other fields. Compared with large roadheaders, it has the characteristics of small size and light weight. , suitable for medium and small coal mine operations, improve the level of mechanization. When construction machinery such as roadheaders are working, due to the large vibration generated, the support may be unstable and prone to slipping, endangering equipment and personal safety, especially when working uphil...
