The multi-section binding oil cylinder comprises a first-stage oil cylinder body, a second-stage oil cylinder body and a multi-stage oil cylinder body, a cylinder barrel of the first-stage oil cylinder body is welded to a cylinder barrel of the second-stage oil cylinder body through a first supporting block, and one side of a piston rod of the second-stage oil cylinder body is connected with a cylinder barrel of the next-stage oil cylinder body through a second supporting block; a through-flow block is fixed to one side of the second-stage oil cylinder and one side of the next-stage oil cylinder, first sealing rings are arranged on the two sides of the through-flow block, and an oil pipe is installed on one side of a cylinder barrel of the first-stage oil cylinder and one side of a cylinder barrel of the second-stage oil cylinder and communicated with the cylinder barrel of the first-stage oil cylinder. By arranging the first buffering sleeve, the second buffering sleeve, the spring and the buffering adjusting ring, a good bidirectional buffering effect can be achieved in the stretching and retracting process of the oil cylinder, hydraulic impact is reduced, and the stability of mechanical movement and the personal safety of an operator are guaranteed. And the cylinder barrel and the piston rod are connected and synchronously move to unfold and can be superposed after being recovered, so that the length of the oil cylinder is shortened, the volume is reduced, and the required mounting space is reduced.

    本发明公开了一种应用于高空作业车且带双向缓冲的多节捆绑油缸,包括一级油缸、二级油缸和多级油缸,所述一级油缸缸筒通过第一支撑块与二级油缸缸筒焊接,且二级油缸的活塞杆一侧通过第二支撑块连接有下一级油缸的缸筒,所述二级油缸与下一级油缸的一侧固定有通流块,且通流块的两侧设置有第一密封圈,所述一级油缸缸筒与二级油缸缸筒的一侧安装有油管相通。本发明通过设置第一缓冲套、第二缓冲套、弹簧和缓冲调节圈能够在油缸伸展和回收过程中实现较好的双向缓冲效果,减少液压冲击,保证机械运动的平稳性及操作者的人生安全。且缸筒与活塞杆连接同步运动展开,回收后可叠加,缩短了油缸的长度,缩小了体积,减少了所需的安装空间。
