Abstract

The invention discloses an engineering machine turntable which comprises a base (10), a first mounting member (21) and a second mounting member (22). The first mounting member (21) and the second mounting member (22) are used for mounting an engineering machine and are respectively fixed on the base. The base (10) comprises a circular part (11) and an extension part (12) extending from one side of the round part (11). The downside of the first mounting member (21) and the downside of the second mounting member (22) are fixed on the circular part (11) and the extension part (12) respectively in the extension direction of the extension part (12). The base is structurally modified, and accordingly inclination of stressed sides of the first and second mounting members is alleviated so as to reduce local stress and to improve strength of the turntable. The invention further discloses an engineering machine with the engineering machine turntable.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an engineering machinery turntable and an engineering machinery. Background technique [0002] In construction machinery, the turntable has the function of connecting the top of the boom and the bottom of the construction machinery, and also has the function of loading and rotating cloth on the boom. In recent years, long boom construction machinery has gradually dominated the market, and a notable feature of long boom construction machinery is that the hinge holes on the turntable are inclined towards the cab, so that a larger boom design space can be obtained. In addition, when the jib is lengthened, the section of each jib is correspondingly enlarged. In order to ensure that the construction machinery is not oversized when the vehicle is running, the turntable of the construction machinery tends to be set as an inclined turntable with a large inclination angle.
