Description
本申请涉及作业机械技术领域，尤其涉及一种插拔销连接组件、起重机臂架及起重机。The present application relates to the technical field of working machinery, in particular to a plug-in pin connection assembly, a crane jib and a crane.
起重机的副臂连接通常采用接叉和销轴相互配合的连接方式。目前，常使用的插拔销安装连接方式通常有两种。其一是通过人工敲击的方式逐个安装。该安装方式的效率较低，且操作人员的安全难以保障。其二是采用液压油缸驱动插拔销进行插拔连接动作。目前使用的液压插拔销的长度固定，不同截面尺寸的副臂需要配备不同尺寸的液压插拔销，其通用性较差。The jib connection of the crane usually adopts a connection method in which the fork and the pin shaft cooperate with each other. At present, there are usually two ways of installing and connecting plug pins that are commonly used. One is to install them one by one by manual tapping. The efficiency of this installation method is low, and the safety of operators is difficult to guarantee. The second is to adopt the hydraulic oil cylinder to drive the plug pin to carry out the plug connection action. The length of the hydraulic plugging pins currently used is fixed, and jibs with different cross-sectional sizes need to be equipped with hydraulic plugging pins of different sizes, which has poor versatility.
