Crane supporting leg device capable of achieving detection of foundation state

Abstract

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.

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 ...

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 kind of lifting accident will damage the crane in light, and 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 touch the ground. The crane is still at risk of capsizing if the ground subsides
