The invention relates to the technical field of cranes, in particular to a stably supported automobile crane. The stably supported automobile crane comprises a crane rack storage frame. Sealing platesare arranged on the surface of the crane rack storage frame, connecting bushings are arranged on the surfaces of the sealing plates, and a transverse rod is arranged on the inner wall of the crane rack storage frame. The transverse rod penetrates through a supporting column, and the surface of the transverse rod is sleeved with limiting plates. First steel balls are arranged on the surfaces of the limiting plates, a base plate is arranged at the end of the supporting column, a damping pad is arranged on the surface of the base plate, and preformed holes penetrate through the base plate and the damping pad. The stably supported automobile crane has beneficial effects that the preformed holes are formed in the surfaces of the base plate and the damping pad, supporting rotating rods with drill bits penetrate through the preformed holes, and the supporting rotating rods are pushed by hydraulic cylinders while being driven by motors; and in this way, the supporting rotating rods are inserted into the ground, the supporting stability of the supporting column is improved, and the penetration depth of the supporting rotating rods is adjustable.
本发明涉及起重机技术领域,具体为一种承托稳定的汽车起重机,包括起重机机架存放架,起重机机架存放架的表面设置有封板,封板的表面设置有连接套管,起重机机架存放架的内壁设置有横杆,横杆贯穿承托柱,横杆的表面套设有限位板,限位板的表面设置有第一钢珠,承托柱的端部设置有垫板,垫板的表面设置有阻尼垫,垫板和阻尼垫被预留孔贯穿;有益效果为:本发明提出的承托稳定的汽车起重机在垫板和阻尼垫表面开设预留孔,预留孔内部穿过带有钻头的支撑转杆,支撑转杆被电机驱动的同时被液压缸顶推,如此支撑转杆被插入地下,提升承托柱支撑稳定性,且支撑转杆入土深度可调。
