Technical Field

[0001] The utility model relates to the technical field of pipeline construction, in particular to a pipeline hoisting device. Background Art

[0002] Building HVAC pipelines are devices connected by pipes, pipe connectors, valves, etc. for transporting gases, liquids, or fluids with solid particles. The uses of pipelines are very extensive. Building HVAC pipelines are mainly used for heating. When installing pipelines, a pipeline hoisting machine is needed to hoist them to the designated position.

[0003] For example, the Chinese patent with the application number CN202322942772.4 discloses a pipeline hoisting machine for rapid hoisting, including: a base, a boom, a hoisting rope, and a fixing seat. A boom is installed above the base, a hoisting rope is connected to the boom, one end of the hoisting rope is connected to a fixing seat, and a clamp is installed below the fixing seat. And the base serves as a support foundation. For this pipeline hoisting machine for rapid hoisting, the pipeline is placed in the clamp, the worm is rotated to drive the clamping block to move horizontally through the toothed plate, and the pipeline is clamped by the clamping block through the clamping block, realizing that the user can quickly clamp and hoist the pipeline through the hoisting mechanism, saving time and improving efficiency. Rotating the L-shaped handle drives the internal thread block to be snap-fitted and fixed in the card slot. After reversing the rotation of the L-shaped handle to drive the internal thread block to move horizontally, the fixing seat is lifted upward to complete the disassembly, realizing that the user can disassemble and replace the clamp according to the length of different pipelines through the quick disassembly and assembly mechanism, improving the practicability of the pipeline hoisting machine. The boom hoists the object through the hoisting rope. When the boom moves with the pipeline, the hoisting rope and the pipeline will shake. To improve the safety of pipeline hoisting, some hoisting machines will be provided with a ring-shaped bracket on the boom. The ring-shaped bracket is fixed around the hoisting rope to avoid excessive shaking amplitude of the hoisting rope and the object. However, since the bracket is fixed to the boom, a large amount of friction will be generated between the hoisting rope and the bracket.
