The invention provides a crane supporting leg device capable of achieving detection of a foundation state, and relates to the technical field of engineering construction. The crane supporting leg device comprises a supporting leg and a supporting leg base plate, and a detection plate is arranged between the supporting leg and the supporting leg base plate; an induction iron sheet is annularly arranged on the supporting leg base plate, and at least two electromagnetic induction switches used for detecting the induction iron sheet are arranged on the detection plate; an ultrasonic generating probe and an ultrasonic receiving probes which can extend downwards are installed at the bottom of the supporting leg at intervals, and each connected with the supporting leg through a spring separately;and the ultrasonic generating probe and the ultrasonic receiving probe can be inserted into a foundation or abut against the surface of the foundation. According to the crane supporting leg device, the supporting state and the foundation state of the supporting leg of an engineering crane can be rapidly detected before hoisting of the engineering crane, and overturning accidents due to insufficient counterforce of the supporting leg are prevented to a great extent.

    一种可检测地基状态的起重机用支腿装置,涉及工程施工技术领域,其包括支腿和支腿垫板,所述支腿和支腿垫板之间设有检测板,所述支腿垫板上环形设置有感应铁皮,所述检测板上设置有至少两个用于检测感应铁皮的电磁感应开关,所述支腿的底部间隔安装有可往下伸出的超声波发生探针和超声波接收探针,所述超声波发生探针和超声波接收探针分别通过一根弹簧与支腿连接,所述超声波发生探针和超声波接收探针可插入地基中或抵在地基表面。本发明可在工程起重机起吊之前对其支腿处的支撑状态和地基状态进行快速检测,在极大程度上防止发生因支腿反力不足造成的倾覆事故。
