Description

Technical Field

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

[0002] At construction sites, operators often need to transport pipes to higher locations and install them. For example, in the construction of prefabricated structures, pipes are commonly used components. The current way to transport pipes is usually to use some lifting devices to transport the pipes to higher locations. Before transportation, the pipes are often tied with ropes to prevent them from falling.

[0003] At present, there are also some lifting devices that can not only transport pipes, but also provide further stability, so that the safety during transportation is greatly improved. For example, a Chinese patent with publication number CN218642255U discloses an assembled construction lifting device, which not only improves the stability during pipe transportation, but also can transport multiple groups of pipes at a time.

[0004] However, there are also some problems. First, the inclined baffle is used to provide pressure to the pipe to keep the pipe stable, and this pressure comes from the sling, which will cause the pressure provided to the pipe during transportation to be unstable, and the pipe may slide from the side; second, more operations are required before loading the pipe, which is more troublesome.

[0005] Therefore, we proposed a construction pipe lifting device to solve the above-mentioned problems.

[0006] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field.
