Abstract

The invention relates to a plug-in tracked chassis structure comprising a frame and a track carrier. The frame comprises overhanging beams and a middle structure connected with the same. The track carrier comprises a square hole and inner vertical plates; the overhanging beams can be inserted into the square hole; the sectional areas of the roots, in connection with the middle structure, of the overhanging beams and the middle structure decrease from the middle structure to positions far away from the middle structure; The sections of the overhanging beams are designed in a variable form, namely, the sectional areas decrease from the middle structure to the positions far away from the middle structure, the middle structure is made transitional to the overhanging beams, sectional width of the roots of the overhanging beams is increased, stress area is enlarged, stress concentration of the roots is effectively decreased, stress distribution is more reasonable, the thickness of upper and lower cover plates need not be increased, the upper and lower cover plates need not be locally reinforced, strength level of material need not be increased either, manufacturing cost of the frame is decreased, and the frame is easier to manufacture.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a plug-in crawler chassis structure. Background technique [0002] Crawler crane refers to the crane whose lifting operation part is installed on the crawler chassis, and the walking depends on the crawler traveling device. [0003] The crawler chassis includes the frame and the left and right track frames. The track frame is also called the track running device, which is generally composed of a track frame structure, a running mechanism, a driving wheel, a roller, a supporting sprocket, a guide wheel and a track shoe. [0004] For crawler cranes with small tonnage, in order to meet the requirements for the stability of the whole machine during crane operation, as well as the requirements that the crawler frame can be retracted during overall transportation and the width of the whole machine meets the requirements of transportation regulations, plug-in connections a...
