Abstract

The invention discloses a crane supporting leg device capable of detecting a foundation state, and relates to the technical field of engineering construction. The device comprises a supporting leg and a supporting leg base plate, wherein 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, at least two electromagnetic induction switches used for detecting the induction iron sheet are arranged on the detection plate, and an ultrasonic generating probe and an ultrasonic receiving probe which can extend downwards are mounted at the bottom of the supporting leg at an interval, are respectively connected with the supporting leg through a spring, and can be inserted into a foundation or abut against the surface of the foundation. According to the invention, the supporting state of the supporting leg of the engineering crane and the foundation state can be rapidly detected before the engineering crane is lifted, so that an overturning accident caused by insufficient counter force of the supporting leg is prevented to a great extent.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a crane outrigger device capable of detecting foundation conditions. Background technique [0002] In order to increase the lifting capacity of the equipment and the stability of the body of the construction crane, the outrigger structure with a certain span is usually designed. However, in actual work, due to the soft foundation at the outriggers of the engineering crane or the staff's illegal operation without placing the outrigger pads, it will directly lead to insufficient support reaction force of the outriggers of the equipment, and in severe cases, the entire equipment will overturn. The occurrence of this lifting accident ranges from damage to the crane, and can also cause casualties in severe cases. [0003] Existing construction cranes usually install load cells on the four outriggers to detect the support status of the outriggers after the outriggers ...
