Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and in particular relates to a protective device for high-rise building construction and a method of using the same. Background Art

[0002] High-rise construction waste includes concrete (unused concrete from the project), construction debris (old concrete, mortar, and other mineral materials generated by chiseling and plastering), as well as dust, wood, paper, metal, and other types of waste. Existing construction waste recycling equipment for high-rise building waste mostly utilizes elevator shaft space to install transmission pipes, which then transport the waste to the ground, where it is finally transferred to a crushing mechanism for processing. During traditional high-rise building construction, waste cannot be quickly crushed before transportation. The large size of the waste causes a large impact force to be generated during transportation due to gravitational potential energy, making it difficult to transport. Dust generated during transportation cannot be effectively removed, leading to the generation of raised dust. The pipes are not equipped with clearing components, so when blockages occur, they cannot be cleared in a timely manner and require disassembly for clearing operations.

[0003] To this end, Chinese patent CN110092134B discloses a high-rise building waste crushing and conveying protection device, including a crushing box and several conveying pipe sections. The crushing box is fixed to the construction floor, and the conveying pipe sections are laid downward from the construction floor along the elevator shaft; the crushing box is equipped with a material guide, crushing rollers, ears, vertical plates, partitions, hydraulic push rods, movable rods, and multi-tooth cutters, and the middle plate of the partition is evenly provided with coarse material discharge holes; the conveying pipe section includes a rectangular conveying pipe, and the ends of the rectangular conveying pipe are fixed with upper and lower end plates connected by several buffer springs. The rectangular conveying pipe is provided with a dust guide port on one narrow side, and an outer cover with a dust suction pipe is fixed to the outside of the dust guide port. A dredging component is provided in the other narrow side and the inner cavity.

[0004] However, this high-rise construction waste crushing and conveying protection device still has some shortcomings. First, it is suitable for crushing and conveying large pieces of construction waste, but not for conveying small pieces and powdered construction waste. Second, its pipes are large in size, and placement on exterior walls poses a high safety risk. Therefore, it needs to be optimized and improved. Summary of the Invention

The inner cavity of the inner tube serves as a conveying area, and the area between the inner tube and the outer tube serves as a dust suction area. A central shaft is installed at the axis of the conveying area, and several circles of fan blades are fixed on the outside of the central shaft. A swivel is fixed near the two ends of the central shaft, and the movement of the swivel is restricted in the adjacent end plates. The outside of one of the swivels is evenly distributed with convex teeth, and the annular pull belt is sleeved on the outside of the swivel with convex teeth, and the inside of the annular pull belt is evenly distributed with tooth grooves that cooperate with the convex teeth.
