Problems solved by technology

By adopting the method of changing wheels diagonally in batches, the problem of road surface damage when the excavator is moving is solved, and there is no need to add additional power devices, and no need to use large-scale hydraulic equipment. The arrangement of the mechanism is reasonable, ensuring the space utilization of the excavator. and machine stability when changing wheels

Abstract

The invention provides a stable wheel exchange type excavator and a wheel exchange method thereof. The stable wheel exchange type excavator comprises an excavator body, caterpillar band movement mechanisms, wheel type movement mechanisms, power connection mechanisms, auxiliary supporting devices and a control system. The caterpillar band movement mechanisms are divided into four sets, arranged atthe bottom of the excavator body and connected with oblique hydraulic cylinders I. The wheel type movement mechanisms are provided with walking wheels, bent rails and bevel gears I. The bent rails arefixed to the positions below the excavator body and movably sleeved with the walking wheels which are connected with hydraulic cylinders II. The power connection mechanisms are connected with an engine of the excavator and provided with rhombus two-way bevel gears. The rhombus two-way bevel gears are connected with the caterpillar band movement mechanisms and correspond to the bevel gears I. Theauxiliary supporting devices are arranged at the bottom of the excavator body and provided with rotary discs and supporting hydraulic cylinders with fixed drill bits. The stable wheel exchange type excavator is ingenious and unique in design, a wheel exchange mode is flexible, and the excavator is stable in the wheel exchange process and is unlikely to topple over.

Description

technical field [0001] The invention belongs to the technical field of excavating machinery, and relates to a stable wheel-changing excavator and a using method thereof. Background technique [0002] Existing small excavators often need to carry out cross-regional operations during road construction, and the excavators are usually transported by cars. However, when going to and from a short-distance construction site with an interval of about 200 to 500 meters, it is obviously more convenient for a small excavator to move there by itself; Excavators with crawler tracks will leave traces of track tracks when moving, damaging cement or asphalt pavement. In the existing construction technology, in order to protect the road surface, workers need to alternately place the backing boards on the road surface, and the excavator runs slowly on the backing boards, which not only hinders the traffic, but also greatly reduces the moving efficiency of the excavator and increases cost. ...
