The invention discloses a dual-purpose excavator with mutually replaced crawlers and tires. The dual-purpose excavator comprises a lower frame and a walking mechanism. The walking mechanism is provided with crawler-type walking mechanisms, a front walking mechanism and a rear steering walking mechanism. The front walking mechanism is detachably mounted on the lower frame through a front lower frame; the front walking mechanism is provided with a front tire wheel and a straight driving device; the rear walking mechanism is detachably mounted on the lower frame through a rear lower frame; and the rear walking mechanism is provided with rear tire wheels and a steering walking driving device, the number of the crawler-type walking mechanisms is two, the upper crawler-type walking mechanism isprovided with a crawler belt and a crawler belt installation driving mechanism used for installing the crawler belt and driving the crawler belt to rotate, and the crawler belt installation driving mechanism is detachably or fixedly connected with the lower frame. Compared with like excavators in the prior art, the crawler-type excavator has the advantages that the crawler belt and the tires of the whole excavator can be detached and replaced, an automobile is not needed for transportation independently during transferring, an engineering team does not need to buy two excavators with differentwalking modes, and the use cost is greatly reduced.

    本发明公开一种履带轮胎互拆换双用挖掘机,包括下车架和行走机构;行走机构具有履带式行走机构、前行走机构和后转向行走机构,前行走机构通过前下车架拆卸安装在下车架上,前行走机构具有前轮胎车轮和直行驱动装置,后行走机构通过后下车架拆卸安装在下车架上,后行走机构具有后轮胎车轮和转向行走驱动装置,履带式行走机构设置有二个,上履带式行走机构具有履带和供履带安装并驱动履带转动的履带安装驱动机构,上述履带安装驱动机构与上述下车架拆卸或固定连接。与现有技术相比,其能使整个挖掘机能实现履带与轮胎互拆换双用,转运时无需再单独采用汽车来运输,工程队无需购买二辆不同行走方式的挖掘机,大大降低使用成本。
