[0029] Reference Figure 1-6As shown, the utility model provides a technical solution: a flexible air duct installation device for a large-span steel roof structure, comprising a straight pipe 5, a bracket 1, an expansion hook 11, a guide rod 14, an inlet 3 and a plurality of ends 4, two eyebolts 7 are installed on the surface of the two brackets 1, a steel rope adjuster 8 is installed on the surface of the eyebolt 7, a main steel rope 2 is installed between the two steel rope adjusters 8, a clamp 9 is installed on both sides of the main steel rope 2, a suspension steel rope 6 is hooked on the lower surface of the expansion hook 11, a one-way adjustment hook 12 is installed at the lower end of the suspension steel rope 6, an aluminum sleeve 13 is fixedly installed on the upper side of the suspension steel rope 6, two mounting strips 34 are fixedly connected to the outer side of the straight pipe 5, a plurality of mounting holes 35 are opened on the surface of the mounting strip 34, and an S-shaped hook 10 is hooked between the mounting hole 35 and the main steel rope 2.

[0030] The following is a detailed description of its overall specific settings and functions.

[0031] In this embodiment: the side wall of the guide rod 14 is slidably connected with the first limit frame 17, the end side of the guide rod 14 is fixedly connected with the second limit frame 18, the inner sides of the first limit frame 17 and the second limit frame 18 are both rotatably connected with pulleys 19, the outer side of the pulley 19 is placed with a hemp rope 16, the end side of the hemp rope 16 is fixedly connected with a hook 24, and the side walls of the first limit frame 17 and the second limit frame 18 are both provided with two reserved grooves 23. Pulling the two hemp ropes 16, the hemp ropes 16 slide on the surface of the pulley 19 to change the direction of the pulling force of the hemp ropes 16, and the suspension work of the straight pipe 5 can be achieved in the process of pulling the hemp ropes 16. The internal thread of the first limit frame 17 is connected with the screw rod 15, and the screw rod 15 is rotatably connected to the inside of the second limit frame 18. Rotating the screw rod 15 will drive the first limit frame 17 to move away from or close to the second limit frame 18.

[0032] The side walls of the first limiting frame 17 and the second limiting frame 18 are fixedly connected with two positioning blocks 20, and a stop frame 21 is slidably connected inside the positioning block 20, and a first spring 22 is fixedly connected between the stop frame 21 and the positioning block 20. When the stop frame 21 is released, the stop frame 21 will be blocked on the outside of the main steel rope 2 by the elastic force of the first spring 22, so that the main steel rope 2 and the first limiting frame 17 and the second limiting frame 18 can be quickly locked. A slide plate 25 is slidably sleeved on the outside of the hook 24, and a connecting plate 26 is fixedly connected to the outside of the hook 24. A screw pin 27 is threadedly connected inside the connecting plate 26, and the screw pin 27 is rotatably connected to the inside of the connecting plate 26. When the screw pin 27 is rotated, the screw pin 27 will push the slide plate 25 to slide on the surface of the hook 24, so that the port of the hook 24 can be sealed.

[0033] Specifically, the lower surfaces of the first limiting frame 17 and the second limiting frame 18 are fixedly connected with a support rod 28, and the hemp rope 16 is slidably connected to the inside of the support rod 28. By setting the hemp rope 16 to slide inside the support rod 28, the hemp rope 16 is prevented from shaking back and forth.

[0034] A rectangular block 30 is fixedly connected to the surface of the support rod 28, a slide 31 is slidably connected to the inside of the rectangular block 30, a plurality of arc-shaped barbs 32 are fixedly connected to the surface of the slide 31, and a second spring 33 is fixedly connected between the slide 31 and the rectangular block 30. The arc-shaped barbs 32 are tightly fitted to the outside of the hemp rope 16 by the elastic force of the second spring 33. An arc-shaped plate 29 is fixedly connected to the surface of the support rod 28. The arc-shaped barbs 32 can be accurately fitted to the outside of the hemp rope 16 by the arc-shaped plate 29.

[0035] Working principle: first install the two brackets 1 at the pre-installation position, and after determining the position of the hanging point, you need to install the expansion hook 11 at the position of each hanging point, and then hang the suspension rope 6, and then install two sets of main steel ropes 2 between the two brackets 1. By adjusting the steel rope adjuster 8, the tightness of the main steel rope 2 can be adjusted. When the straight pipe 5 needs to be suspended and installed, the screw rod 15 can be rotated, and the screw rod 15 will drive the first limit frame 17 to move away from or close to the second limit frame 18, wherein the first limit frame 17 slides on the surface of the guide rod 14 to limit the moving direction between the first limit frame 17 and the second limit frame 18, and the distance between the first limit frame 17 and the second limit frame 18 is adjusted. The adjustment facilitates the construction of the first limit frame 17 and the second limit frame 18 on the main steel rope 2 at two different width positions. First, pull the baffle frame 21 inside the positioning block 20, and after the reserved grooves 23 on the first limit frame 17 and the second limit frame 18 are sleeved on the outside of the main steel rope 2, release the baffle frame 21, and the baffle frame 21 will be blocked on the outside of the main steel rope 2 by the elastic force of the first spring 22, so that the main steel rope 2 and the first limit frame 17 and the second limit frame 18 can be quickly locked. The side of the hemp rope 16 with the hook 24 is hooked on the inner side of the mounting hole 35 on the mounting strip 34 on the surface of the straight tube 5 on the ground, and the screw pin 27 is rotated. The screw pin 27 will push the slide plate 25 to slide on the surface of the hook 24, so that the port of the hook 24 can be sealed. The safety of lifting the straight tube 5 is improved. At this time, the two hemp ropes 16 are pulled, and the hemp ropes 16 slide on the surface of the pulley 19, which has the effect of changing the direction of the pulling force of the hemp ropes 16. The straight tube 5 can be suspended in the process of pulling the hemp ropes 16. In the process of pulling the hemp ropes 16, the hemp ropes 16 and the arc-shaped barbs 32 will move relative to each other, and the arc-shaped barbs 32 will be tightly fitted to the outside of the hemp ropes 16 by the elastic force of the second spring 33. By setting the hemp ropes 16 to slide inside the support rod 28, the hemp ropes 16 are prevented from shaking back and forth. The setting of the arc plate 29 also prevents the hemp ropes 16 from being squeezed by the arc-shaped barbs 32 and pushed and deflected. The arc plate 29 can make the arc-shaped barbs 32 accurately fit the outside of the hemp ropes 16. The hemp rope 16 has an irreversible effect during the relative movement with the arc-shaped barb 32. When a person accidentally releases the hemp rope 16, the arc-shaped barb 32 will be inserted upside down inside the hemp rope 16, thereby avoiding the straight tube 5 from falling and improving the safety of the straight tube 5 during the hanging process. When the straight tube 5 is suspended to the installation position, the hemp rope 16 is stopped from being pulled, and the staff at a high place can respectively install the S-shaped hook 10 on the inner side of the installation hole 35 and the outer side of the main steel rope 2, thereby realizing the lifting of the straight tube 5. By adjusting the one-way adjustment hook 12, the installation height of the straight tube 5 can be adjusted. By setting the above structure, the flexible lifting and installation of the straight tube 5 is facilitated, and the straight tube 5 is avoided from falling from a high place during the installation process.To a certain extent, the safety of installing the straight pipe 5 is improved.
