The invention provides a telescopic boom frame and a crane, the telescopic boom frame comprises a first section of boom, a second section of boom... an Nth section of boom which are sequentially sleeved from outside to inside, and N is greater than or equal to 3; one of a first piston rod and a first cylinder barrel of the first oil cylinder is connected with the first knuckle arm, and the other one of the first piston rod and the first cylinder barrel is connected with the second knuckle arm; one of a second piston rod and a second cylinder barrel of the second oil cylinder is connected with the second section arm, and the other one of the second piston rod and the second cylinder barrel is connected with the third section arm; one of an (N-1) th piston rod and an (N-1) th cylinder barrel of the (N-1) th oil cylinder is connected with the (N-1) th section of arm, and the other one of the (N-1) th piston rod and the (N-1) th cylinder barrel is connected with the Nth section of arm; the arrangement positions of the first oil cylinder, the second oil cylinder... the (N-1) th oil cylinder are mutually independent and do not interfere with each other in telescopic movement. In this way, the use of a rope row is omitted, and the shock resistance of the telescopic boom frame is enhanced; all the oil cylinders do not need to stretch out and draw back in sequence, and then all the knuckle arms are driven to stretch out and draw back freely and independently, so that the crane has higher working efficiency.
本申请提供了一种伸缩臂臂架及起重机,该伸缩臂臂架包括由外至内依次套设的第一节臂、第二节臂……第N节臂,N≥3;还包括:第一油缸,其第一活塞杆、第一缸筒中的一者与第一节臂连接、另一者与第二节臂连接;第二油缸,其第二活塞杆、第二缸筒中的一者与所述第二节臂连接、另一者与第三节臂连接;……第N‑1油缸,其第N‑1活塞杆、第N‑1缸筒中的一者与第N‑1节臂连接、另一者与第N节臂连接;第一油缸、第二油缸……第N‑1油缸的设置位置彼此独立、伸缩移动互不干涉。如上,省去了对绳排的使用,增强了伸缩臂臂架的抗冲击性能;各油缸不需要按照顺序伸缩,进而驱动各节臂彼此独立的任意伸缩移动,使得起重机具有更高的工作效率。
