Rotary table main body structure and crane provided with same

Abstract

The embodiment of the invention discloses a rotary table main body structure and a crane provided with the same. The rotary table main body structure comprises a first assembly and a second assembly, wherein the first assembly is connected with the second assembly through a detachable connection structure; the rotary table main body structure has a length direction, a width direction and a thickness direction; and the first assembly and the second assembly are locked together by the detachable connection structure at least in the width direction of the rotary table main body structure. The crane comprises the rotary table main body structure provided by the invention, wherein at least one of a suspension arm, a swing mechanism, a winding mechanism, a power system, a hydraulic system and a swing platform of a cab is arranged on the rotary table main body structure. The rotary table main body structure disclosed by the invention can be used for overcoming the limitation, caused by the transportation clearance, on the width size of the rotary table main body structure, and can be used for solving the technical problem that the space requirements of the assembly and the maintenance of parts can not be met due to the limitation, caused by the transportation clearance, on the width size of the rotary table main body structure in the prior art.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a main structure of a turntable and a crane provided with the main structure of the turntable. Background technique [0002] Among the major structural parts of the crane, the turntable is the key load-bearing structural part used to connect the crane to get on and off. [0003] In the existing crawler cranes, most of the turntables adopt the traditional monolithic structure. The turntable with integral structure includes a main structure of the turntable and an auxiliary structure, and the main structure of the turntable and the auxiliary structure are detachably connected. [0004] Such as figure 1 Shown is an existing main body structure of a turntable, which includes a left vertical plate 10, a right vertical plate ( figure 1 Not shown in ) and the installation box between the left side vertical plate 10 and the right side vertical plate for installing parts, the left si...
