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 wheel-changing excavator and a method for using the excavator, comprising an excavator body, a crawler moving mechanism, a wheeled moving mechanism, a power connection mechanism, an auxiliary support device and a control system; the crawler moving mechanism is divided into four groups , set at the bottom of the excavator body, and connected with a "eight"-shaped inclined hydraulic cylinder I; the wheeled moving mechanism is provided with traveling wheels, curved tracks and helical gears I; the curved track is fixed on the excavation The bottom of the excavator body is bent downward; the traveling wheel is movably sleeved on the curved track and connected to the hydraulic cylinder II; the power connection mechanism is connected to the engine of the excavator and is provided with a diamond-shaped two-way helical gear; The diamond-shaped two-way helical gear is connected with the crawler belt moving mechanism and corresponds to the helical gear I; the auxiliary supporting device is arranged at the bottom of the excavator body. The invention has ingenious design, unique and practical wheel changing form, and can be flexibly applied to excavator equipment.

Description

technical field [0001] The invention belongs to the technical field of excavating machines, and relates to a 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 generally 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. Theref...
