Heavy three-way pipe hoisting device

Abstract

The invention discloses a heavy three-way pipe hoisting device which comprises a lifting mechanism and an embedded hoisting mechanism, wherein the lifting mechanism comprises a lifting disk and a lifting straight rod perpendicularly fixed together with the lifting disk; the lifting disk is a circular disk; a hanging ring for fixing a steel wire rope is arranged at the upper end of the lifting straight rod; the embedded hoisting mechanism comprises a fixing seat and arc-shaped stretching claws fixedly arranged on the outer wall of the fixing seat through hinge shafts; the arc-shaped stretching claws are concave arcs; the lifting disk is positioned on the fixing seat and is arranged between the two opposite arc-shaped stretching claws; a through hole, through which the steel wire rope passes, is formed in the fixing seat. According to the heavy type three-way pipe hoisting device, the front end of the embedded type hoisting mechanism extends into a perpendicular pipe orifice of a three-way pipe, and then the steel wire rope is used for lifting up the lifting straight rod to drive the lifting disk to rise up; by virtue of upward movement of the lifting disk, the arc-shaped stretching claws are driven to be unfolded; furthermore, the upward movement distance of the lifting disk is larger, and the unfolding angles of the arc-shaped stretching claws are larger; the unfolded arc-shaped stretching claws can be very effectively clamped in the three-way pipe, so that locked lifting is realized.

Description

technical field [0001] The invention relates to a hoisting device for a machine, in particular to a device for hoisting a heavy tee pipe. Background technique [0002] At present, when hoisting large-scale tee pipes, the existing cranes generally use steel wire ropes to be inserted into the tee pipe and then wound for hoisting. In this way, the inner wall of the tee pipe will be worn during the hoisting process, especially the edge of the tee pipe is easy to wear gaps. It can be very difficult to install the seal on the duct. Contents of the invention [0003] Aiming at the above technical problems, the present invention proposes a device for hoisting heavy tee pipes. [0004] In order to achieve the above purpose, it is realized through the following technical solutions: [0005] Heavy-duty tee pipe hoisting device, including hoisting mechanism and embedded hoisting mechanism; [0006] The lifting mechanism includes: a lifting plate and a lifting straight rod fixed ver...
