The invention relates to the technical field of engineering operation machinery, in particular to a crane frame with a supporting function. The crane frame comprises a walking truck, a crane, four groups of multi-stage hydraulic supporting devices, a supporting protective plate, and a levelness monitoring device; the crane is arranged on the walking truck; the four groups of multi-stage hydraulicsupporting devices are arranged below the crane; the supporting protective plate is arranged on the lower side of the crane; the supporting protective plate is connected with the crane through a plurality of first hydraulic cylinders; and the levelness monitoring device is arranged at the center of the lower side of the supporting protective plate. The crane frame has the beneficial effects that the four groups of multi-stage hydraulic supporting devices arranged below the crane can form an X shape, so that the supporting area is enlarged, and the stability of the crane during working is better; when a larger supporting area needs to be obtained, the supporting area can be adjusted through the multi-stage hydraulic supporting devices, so that the working area of the crane is larger; and furthermore, the levelness monitoring device is further arranged, so when the crane inclines, alarming and auxiliary correcting work can be improved, and the safety of the crane in the working process is improved.

    本发明涉及工程作业机械技术领域,具体涉及一种具有支撑功能的吊车架,包括:行走卡车以及设置在行走卡车上的吊车;设置在吊车下方的四组多级液压支撑装置;支撑护板,所述支撑护板设置在吊车下侧,且支撑护板通过多个第一液压缸与吊车相连;水平度监测装置,所述水平度监测装置设置在支撑护板下侧中央处。本发明的有益效果是设置在吊车下方的四组多级液压支撑装置可以形成一个X形,扩大了支撑面积,使吊车工作时的稳定性更好;当需要获得更大的支撑面积时,可通过多级液压支撑装置来调节支撑面积,使吊车的工作面积更大;此外,还配置有水平度监测装置,当吊车在发生倾斜时可以提高报警以及辅助纠正工作,扩大了吊车在工作时的安全性。
