The invention discloses a movable hydraulic supporting structure for an engineering truck, and relates to the technical field of crane supporting. Comprising a telescopic transverse moving part, a vertical telescopic part is installed on the telescopic transverse moving part, and the vertical telescopic part is used for supporting a crane in a telescopic mode; a horizontal supporting leg part is mounted on the vertical telescopic part; the vertical telescopic part is used for controlling the horizontal supporting of the horizontal supporting foot part; an anti-damage limiting part is mounted on the telescopic transverse moving part; the anti-damage limiting part is used for preventing the vertical telescopic part from being recycled in advance; the vertical telescopic part can be used for detecting the horizontal state of the ball sleeve, it is guaranteed that the sliding supporting foot disc can be supported on the ground or a sleeper in the horizontal state, the supporting stability of the structure can be guaranteed, and the problem of unstable supporting such as slipping caused by inclination of the sliding supporting foot disc is solved. The problems that according to an existing hydraulic supporting structure, a transverse moving part is directly recycled, irreversible damage and even breaking are easily caused to a vertical supporting hydraulic cylinder, and automatic safety limiting is inconvenient are solved.
本发明公开了一种工程车用可移动式液压支撑结构,涉及吊车支撑技术领域;包括伸缩横移部,所述伸缩横移部上安装有竖向伸缩部,所述竖向伸缩部用于伸缩支撑吊车;所述竖向伸缩部上安装有水平支脚部;所述竖向伸缩部用于控制水平支脚部水平支撑;所述伸缩横移部上安装有防损伤限位部;所述防损伤限位部用于防止提前回收竖向伸缩部;采用竖向伸缩部可以用于检测球套的水平状态,确保滑动支脚盘可以保持水平状态支撑在地面或枕木,可以保证本结构支撑稳定性,避免滑动支脚盘歪斜造成打滑等支撑不稳的问题;以解决目前的液压支撑结构直接回收横移部分容易对竖向支撑液压缸造成不可逆损伤甚至折断,不便于自动保险限位的问题。
