The invention belongs to the technical field of crane design, and particularly relates to a fixed mounting structure suitable for a lorry-mounted crane, which comprises three groups of bolt assemblies and two limiting plates, under the condition that a vehicle is not provided with an auxiliary beam, limiting is conducted through a bolt assembly and a limiting plate, and the limiting plate is of a sheet body structure, is installed below a crane cross beam and is connected with the crane cross beam in a matched mode through two 90-degree limiting faces. The limiting plates are arranged on the left side and the right side respectively, clamp the longitudinal beam of the vehicle in the middle and are connected with the longitudinal beam of the vehicle through bolts and nuts, and the crane can be fixed and limited in the longitudinal direction and the left-right direction of the vehicle at the same time. The lorry-mounted crane solves the problems of mounting, fixing and limiting of the lorry-mounted crane under the condition that a vehicle is not provided with an auxiliary beam.
本发明属于起重机设计技术领域,具体涉及一种适用于随车起重机的固定安装结构,包括:三组螺栓组件和两个限位板;在车辆没有副梁的情况下,通过螺栓组件和限位板的方式进行限位,限位板采用片体结构,安装位置在起重机横梁下方,与起重机横梁通过两个呈90°的限位面相配合连接;限位板左右两侧各一个,将车辆车辆纵梁卡在中间,与车辆车辆纵梁通过螺栓和螺母相连接,可同时实现起重机在车辆纵向及左右方向的固定和限位。本发明解决了车辆没有副梁的情况下随车起重机的安装固定及限位的问题。
