Abstract

The invention provides an automatic inflating wheel changing excavator and a wheel changing method thereof. The automatic inflating wheel changing excavator comprises an excavator body, four caterpillar band moving mechanisms, a wheel type moving mechanism, a power connecting mechanism, an auxiliary supporting device and a control system. The caterpillar band moving mechanisms are arranged at thebottom of the excavator body and are connected to a hydraulic cylinder I; a walking wheel, a bending track, a bevel gear I and an automatic detecting and air supplementing device are arranged on the wheel type moving mechanism; the bending track is fixed below the excavator body; the walking wheel is movably connected to the bending track in a sleeving mode and is connected to a hydraulic cylinderII; the power connecting mechanism is connected to an engine of the excavator and is provided with a rhombic bidirectional bevel gear; the rhombic bidirectional bevel gear is connected to the caterpillar band moving mechanisms and corresponds to the bevel gear I; and the auxiliary supporting device is arranged at the bottom of the excavator body. The automatic inflating wheel changing excavator is skillful in design and unique and practical in wheel changing form. The tire pressure is kept normal, and the automatic inflating wheel changing excavator can be flexibly applied to excavator equipment.

Description

technical field [0001] The invention belongs to the technical field of excavating machinery, and relates to an automatic inflatable wheel-changing excavator and a use 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 inc...
