Abstract

The invention provides leg type engineering machinery, and relates to the technical field of the engineering machinery. The leg type engineering machinery comprises a working main body and a pluralityof vertical legs for supporting the working main body, wherein the vertical legs comprise vertical leg cylinders, leg discs and leg reaction force sensors, the leg reaction force sensors are connected between the vertical leg cylinders and the leg discs, the vertical leg cylinders are used for adjusting the length of the vertical legs, the leg reaction force sensors are used for detecting the legreaction force, and the leg discs are used for carrying the leg reaction force sensors and supporting the sensors on the ground. The leg reaction force of the leg type engineering machinery has smallmonitoring result error, and the engineering machinery has higher safety.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a leg-type engineering machinery. Background technique [0002] Outrigger construction machinery includes truck cranes, concrete pump trucks, etc., which use multiple outriggers to support the entire work body during work. Due to reasons such as uneven roadbed, subsidence of roadbed or soft roadbed, overturning accidents often occur in outrigger construction machinery during operation. In order to prevent the construction machinery from overturning accidents during operation, the outrigger construction machinery uses sensors to monitor the reaction force of the outriggers to monitor the safety status of the construction machinery. However, the monitoring result error of the outrigger reaction force sensor of the existing outrigger construction machinery is large, which is not conducive to ensuring the safety of the construction machinery. Contents of the inventio...
