Supporting structure and crane with same

Abstract

The invention provides a supporting structure and a crane with the same. The supporting structure comprises a rotating stand column (1), a plurality of level landing legs (3), a plurality of vertical landing legs (7), a supporting base (9) and a bearing landing leg disc (8), wherein one ends of the level landing legs (3) are respectively hinged to the peripheral surface of the rotating stand column (1) around the peripheral surface of the rotating stand column (1); the upper ends of the vertical landing legs (7) are respectively connected with one corresponding landing leg of the level landing legs (3), and the lower ends of the vertical landing legs are respectively connected with the bearing landing leg disc (8); especially, each level landing leg (3) is provided with a sliding rail (5), and the upper end of each vertical landing leg (7) is provided with a sliding sleeve (6) matched with the slide rail (5) so that each vertical landing leg (7) can move relative to the corresponding level landing leg (3). The supporting structure can be used for large-sized engineering machine and particularly used for supporting the lifting operation of the crane and the positioning regulation before the supporting and has the advantages of simple structure, light weight, convenient installation, strong carrying capacity, and the like.

Description

technical field [0001] The invention relates to a support mechanism and a crane with such a support structure. Background technique [0002] When the crane is hoisting on soft ground, the supporting foundation is used to support the crane on the foundation through the supporting structure. Since the supporting foundation is fixed and the supporting area is limited, in order to improve construction efficiency, relative movement between the vertical outrigger and the ground is required during positioning adjustment, that is, the rotation of the vertical outrigger around the slewing column and the movement along the horizontal outrigger are required. translational movement. [0003] In order to achieve this purpose, in the supporting structure of the prior art, the horizontal support leg adopts a sleeve-type structure, and the translational movement of the vertical support leg is realized through the expansion and contraction of the horizontal support leg itself (such as Figu...

AI Technical Summary

Problems solved by technology

Although the sleeve-type structure shown in the figure can realize the above-mentioned translational movement, there are a series of problems in this structure: First, in order to meet the load-bearing requirements, there is a certain overlapping part between the two sections of the sleeve. The load is large, so the structural strength of the overlapping part is required to be high, resulting in an increase in the weight of the overlapping part; in addition, the overlapping part also leads to an increase in manufacturing materials, an increase in processing costs, and an increase in the weight of the entire mechanism
