Large-diameter heavy pipe lifting device

Abstract

The invention discloses a large-diameter heavy pipe lifting device, which comprises a lifting base and a lifting rod, wherein a threaded rod is arranged at the lower part of the lifting rod, and is mounted at the center position of the upper end surface of the lifting base through a thread; the thread part of the lifting rod is sleeved with a locking nut; and the structure is mainly used for enhancing the fixing stability of the lifting rod and the lifting base. According to the technical scheme, firstly, a to-be-lifted round pipe is vertically put on the upper end surface of the lifting base; the lifting rod is inserted, assembled and fastened; a left oblique rod and a right oblique rod are pulled out in the radial direction at the lower part and are fastened together with aligned through holes through bolt assemblies; and the condition that the outer walls of the left oblique rod and the right oblique rod cling to the inner wall of the to-be-lifted round pipe can be ensured, so that direct lifting can be carried out.

Description

technical field [0001] The invention relates to a large-diameter heavy pipe hoisting device. Background technique [0002] At present, the hoisting of large-diameter heavy pipes has always been difficult. Generally, steel wire ropes are used for direct hoisting, which has low safety and is easy to wear heavy pipes and wire ropes. When hoisting through frames, the frame itself requires high strength and heavy weight, resulting in energy waste. A light structure for the hoisting of heavy pipes with large diameters is very necessary. Contents of the invention [0003] Aiming at the above technical problems, the present invention proposes a light structure for hoisting heavy pipes with large diameters. [0004] In order to achieve the above purpose, it is realized through the following technical solutions: [0005] Large-diameter heavy pipe hoisting device, including hoisting base and hoisting rod; [0006] The hoisting base is disc-shaped; [0007] The lower part of the l...
