Cantilever crane structure for concrete pump truck
The invention discloses a cantilever crane structure for a concrete pump truck. The structure comprises a rotating base and a cantilever crane telescopic swinging device; the cantilever crane telescopic swinging device comprises a cantilever crane swinging assembly and a cantilever crane telescopic assembly, the cantilever crane telescopic assembly comprises a plurality of cantilever cranes connected section by section and a plurality of telescopic driving mechanisms connected between adjacent cantilever cranes, the telescopic driving mechanism comprises a first hydraulic driving component, a controller, driving execution assemblies, electromagnets and electromagnetic attraction assemblies, a plurality of driving array holes are formed in the length direction of the outer wall of each cantilever crane, the electromagnetic attraction assembly is fixedly connected with another electromagnetic attraction assembly, the controller is used for sending out a telescopic control instruction, so as to control the electromagnets to attract or release the electromagnetic attraction assemblies, so that the driving execution assemblies are buckled in the corresponding driving array holes, and the plurality of cantilever cranes which are connected section by section stretch and retract. The structure is simple, low in manufacturing cost, high in automation control degree, and high in swing and telescopic control precision; and the working efficiency is improved and the labor cost is reduced.
本发明公开了一种混凝土泵车用臂架结构，包括转动底座和臂架伸缩摆动装置，臂架伸缩摆动装置包括臂架摆动组件和臂架伸缩组件，臂架伸缩组件包括多个逐节连接的臂架及连接于相邻臂架之间的多个伸缩驱动机构，伸缩驱动机构包括第一液压驱动构件、控制器、驱动执行组件、电磁铁和电磁吸引组件，沿臂架外壁的长度方向上均设有多个驱动阵列孔，电磁吸引组件与电磁吸引组件固定连接，控制器用于发出伸缩控制指令，控制电磁铁吸合或释放电磁吸引组件，以促使驱动执行组件扣合于相应的驱动阵列孔内，以对多个逐节连接的臂架进行伸缩。本发明结构简单、制作成本低；自动化控制程度高、摆动和伸缩控制精度高；提高工作效率、降低人工成本。
