The invention discloses a small tower crane inclined rear pull rod connecting device. The device comprises a tower cap, a balance arm and an inclined rear pull rod, wherein the end part of the balancearm is hinged to the bottom of the tower cap, the inclined rear pull rod is connected with the other end of the balance arm and the top part of the tower cap, and the balance arm is hinged with the inclined rear pull rod through a rotatable connection assembly. The device has the following beneficial effects that the device provides a flexible and reliable connection device for the self-installation and disassembly of the balance arm of the small tower crane, so that the original fixed connection hinge point becomes the rotatable connection hinge point, the balance arm and mechanisms and structural components on the balance arm are smoothly pulled up or rotated and put down through the inclined rear pull rod, the installation and disassembly workloads of the installation and disassembly and transportation working conditions are reduced to the maximum extent, so that the conversion of the installation and disassembly and transportation working conditions becomes faster.
一种小型塔式起重机械斜后拉杆连接装置,包括塔帽、平衡臂和斜后拉杆,平衡臂端部铰接于塔帽底部,斜后拉杆分别与平衡臂另一端以及塔帽顶部连接,所述平衡臂与斜后拉杆之间通过可旋转式连接组件铰接。有益效果:本发明为小型塔式起重机械的自安装、拆卸平衡臂提供了灵活可靠的连接装置,使原固定的连接铰点成为可旋转的连接铰点,实现了通过斜后拉杆顺利扳起或旋转放下平衡臂及其上的机构、结构部件,最大限度地减少了安装、拆卸及运输工况的安装及拆卸工作量;也使安装、拆卸及运输工况的转换变得更快捷。
