Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically to a transportation and installation system for pipeline layout in buildings. Background Technology

[0002] After prolonged operation, central air conditioning systems in building structures often exhibit aging equipment, low efficiency, and high energy consumption, necessitating upgrades and renovations. In industrial buildings, the central air conditioning systems, including cooling water pipes, cooling tower pipes, and chilled water pipes, are typically installed on the roof structure. Traditional pipe installation methods primarily involve setting up roof pipe supports, using angle steel to directly support the pipes on the roof panels or small-section roof beams. However, existing pipe installation structures have the following shortcomings:

[0003] 1) Due to the limited load-bearing capacity of the existing building structure roof design, the installation of roof pipe supports is relatively difficult. In addition, there are many existing roof process pipes in industrial buildings, which will affect the layout, installation and transportation of air conditioning pipes.

[0004] 2) Installing roof pipe supports on the roof panels can easily damage the roof's waterproofing layer, leading to roof leaks;

[0005] 3) Roof pipe supports are directly supported on small-section roof beams or roof panels, which can easily cause local roof deformation exceeding the standard requirements, resulting in local roof damage and leakage.

[0006] 4) The roof pipe supports are directly supported on the small cross-section beams or roof panels of the roof. In addition, the large roof area makes it difficult to transport and lift the air conditioning pipes horizontally on the roof. This requires a large amount of labor, is high-intensity, and has low efficiency in pipe transportation and installation. Utility Model Content

The lower ends of the two sets of steel columns 21 are fixed to the upper part of the concrete structural column 1. The diagonal support 23 is fixed in an inclined manner between the steel column 21 and the steel frame beam 22. The steel frame beam 22 and the steel column 21 are connected by the diagonal support 23 to form a triangular stable structure. In specific implementation, each set of steel columns 21 is made of HN250×125×6×9 hot-rolled H-beams, and the steel frame beams 22 are made of HN250×125×6×9 steel. The two ends of the steel frame beams 22 are connected to the flanges of the steel columns 21 by fixing components. High-strength bolts are used for these fixing components. The diagonal supports 23 are also fixed between the steel frame beams 22 and the steel columns 21 by high-strength bolts. The roller transport structure 4 includes two sets of bearing fixing seats 41, a rotating shaft 42, and roller sleeves 43. The two sets of bearing fixing seats 41 are symmetrically installed on the steel frame beams 22 of the portal steel frame 2.

This utility model fixes the portal steel frame 2 to the upper end of the concrete structural column 1, ensuring the stability of the portal steel frame 2. At the same time, it can directly transfer the load of the pipe 3 on the portal steel frame 2 to the concrete structural column 1, solving the problem of insufficient bearing capacity of the traditional roof pipe 3 support fixed on the roof panel. The portal steel frame 2 of this utility model is provided with diagonal support 23, which can improve the seismic performance of the portal steel frame 2 and reduce the cross section material of the steel frame beam 22. The crane 7 lifts the pipe 3 from the ground onto the roller transport structure 4 of the portal steel frame 2.

The two sets of fixing parts 512 are located on the outside of the U-shaped opening groove 511. The anti-slip safety hoop 51 covers the outer periphery of the roller device through the U-shaped opening groove 511. The anti-slip safety hoop 51 passes through the two sets of fixing parts 512 and the steel frame beam 22 in sequence through the connecting bolt 52. The nut 53 is threadedly connected to the connecting bolt 52 to lock and fix the anti-slip safety hoop 51 to the steel frame beam 22. This utility model features an anti-slip safety hoop 51 on the outer periphery of the roller device, which ensures that the pipe 3 will not slip during transportation, prevents damage to the pipe 3, and improves the stability of the pipe 3 during transportation. The anti-slip safety hoop 51 is made of flat steel bent into a U-shape and is fixed to the anti-slip safety hoop 51 by connecting bolts 52. The anti-slip safety hoop 51 can be made of Q235 carbon steel, 5mm thick, and 50mm wide flat steel bent into a U-shaped structure with an inner diameter 10-20mm larger than that of the pipe 3. The connecting bolts 52 are M12 stainless steel bolts.

[0039] like Figures 5-7As shown, in a specific implementation of this utility model embodiment, a telescopic boom 71, a lifting structure 72, and a lifting tool 8 are fixed on a crane 7. The telescopic boom 71 is installed on the crane 7. One end of the lifting structure 72 is connected to the telescopic boom 71, and the other end of the lifting structure 72 is connected to the lifting tool 8. The lifting tool 8 includes a U-shaped clamp 81, a lifting ring 82, and an adjusting ring 83. One straight side of the lifting clamp beam of the U-shaped clamp 81 is provided with a plurality of lifting holes 811 and lifting adjusting holes 812. The plurality of lifting holes 811 are distributed alternately on the straight side of the lifting clamp beam of the U-shaped clamp 81 from left to right.

A main lifting strap 84 is provided above the lifting ring 82, and an auxiliary lifting strap 85 is provided above the adjusting ring 83. The main lifting strap 84 passes through the lifting ring 82 and is connected to the main lifting rope assembly 721 of the lifting structure 72. The auxiliary lifting strap 85 passes through the adjusting ring 83 and is connected to the auxiliary lifting sling assembly 722 of the lifting tool 8. The crane 7 of this utility model uses the lifting ring 82 of the U-shaped clamp 81 as the main force point for lifting the pipe 3. By cooperating with the lifting structure 72 and the telescopic boom 71, the U-shaped clamp 81 can be inserted into the pipe 3 to complete the lifting work of the pipe 3, reducing the input of labor and labor costs, and also reducing the safety hazards of workers. The U-shaped clamp 81 has lifting holes 811 at different positions, which can effectively solve the problem of center of gravity shift caused by different pipe lengths. The crane 7 of this utility model has a simple structural design, which can prevent the pipe 3 from accidentally falling off during the lifting process. By inserting the U-shaped clamp 81 into the outer wall of the end of the pipe 3, the pipe 3 can be protected and the outer skin of the pipe 3 can be prevented from being excessively scratched by binding. It can achieve the purpose of fast and simple lifting, and greatly improve the overall work efficiency of lifting and installing the pipe 3.

[0040] This invention features an anti-slip part 813 installed inside the straight-side lifting beam of the U-shaped clamp 81. The lifting tool 8 is secured to the outer wall of the end of the pipe 3 via the anti-slip part 813. The anti-slip part 813 inside the U-shaped clamp 81 ensures a firm grip on the pipe 3, preventing slippage and ensuring a secure clamping that prevents the pipe 3 from falling off during lifting. The entire U-shaped clamp 81 has a simple structure, is easy to clamp, has low manufacturing cost, requires no complex clamping components, and is easy to use. The anti-slip part 813 has a serrated structure and is made of rubber anti-slip material. This ensures good protection at the contact point between the U-shaped clamp 81 and the pipe 3 when the U-shaped clamp 81 is inserted into the outer wall of the end of the pipe 3, preventing wear and damage to the pipe 3 during lifting.
