Telescopic mechanism of wetland excavator walking device

Abstract

The invention relates to a telescopic mechanism of a wetland excavator walking device, which comprises a left floating box and a right floating box. An intermediate frame is arranged between the left floating box and the right floating box; the intermediate frame is provided with mutually parallel connecting through holes; the two floating boxes are connected with the intermediate frame together through steel girders fixed on the floating boxes; the steel girders are inserted in respective connecting through holes and are connected in a staggered shape; the extension of the steel girders is controlled by a telescopic oil cylinder, one end of the steel girder is arranged inside a left waking device, and the other end of the steel girder is arranged inside a right walking device; and when the left and right floating boxes are completely contracted, the steel girder of the left floating box is hidden in the right floating box, and the steel girder of the right floating box is hidden in the left floating box. The telescopic mechanism saves the transportation cost and the time required for assembly and disassembly and improves the work efficiency. The whole side excavating range can beincreased when a chassis is completely contracted; and a driver can clearly look so as to avoid the phenomenon of improperly excavating the walking device via the conventional wetland excavator bucket.

Description

technical field [0001] The invention relates to a wetland excavator, in particular to a telescopic mechanism of a walking device of the wetland excavator. Background technique [0002] The position of the traveling device on both sides of the existing traditional wetland type excavator is fixed, which causes the problems of difficult transportation, high transportation cost, and time-consuming disassembly and assembly. And because the running gear on both sides is wide, the driver cannot clearly and accurately visually inspect it, thus causing the phenomenon that the bucket of the traditional wetland excavator digs the running gear by mistake. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the object of the present invention is to provide a telescoping mechanism of the walking device of a wetland excavator, which is controlled by a telescopic oil cylinder. It reduces the transportation cost and the time required for di...
