Guide wheel, track system and engineering machinery

Abstract

The invention discloses a guide wheel, a crawler system and engineering machinery. The guide wheel comprises a left supporting seat, a right supporting seat, a guide wheel moving assembly and a fastener, the left supporting seat and the right supporting seat are symmetrically mounted on two sides of the bracket; the two sides of the guide wheel moving assembly are installed between the left supporting base and the right supporting base through connecting pieces correspondingly. The fasteners are installed on the connecting pieces on the two sides respectively, the guide wheel moving assembly axially moves between the left supporting base and the right supporting base by loosening the fasteners on the two sides, and after the guide wheel moving assembly moves by a preset distance, the guide wheel moving assembly is fixed to the left supporting base and the right supporting base by tightening the fasteners on the two sides. Left-right movement of the guide wheel relative to the supporting seat is achieved, height change of the axis of the guide wheel is achieved, and different requirements during track replacement are met.

Description

Technical field [0001] The invention is applicable to the field of construction machinery, in particular, to a guide wheel. Background technique [0002] The current guiding wheel structure is widely used in the construction machinery structure, and the leading track is mainly bypassing in the track chassis walking process, preventing the role of track running and the traveler. In general, in the guide wheel mounting process, the guide wheel is required to be in the main pulse of the main leader, thereby correctly guiding the track bypass, but in the actual production, the guide holder is in the process of welding with the main bank, among the main lines. There is a deviation in the pair of beam lines, coupled with the gap between the guide wheel rails, thereby causing the guide wheel offset, and the crawler is biased under the guidance of the guide wheel during the walking process, further causing four rounds. The wear of a belt causes the use of faults, and the correction metho...

Problems solved by technology

In this patent, the additional adjustment part is the key to the height of the axis of the guide wheel, but the adjustment part is connected to the guide seat through bolts. In the process of realizing the first posture and the second posture of the guide wheel, the adjustment part needs to be adjusted After dismantling, flipping and reinstalling, the narrow internal space of the guide seat makes it inconvenient to disassemble the fixing bolts, and at the same time, it is impossible to realize the axial left and right movement of the guide wheel
