Description

Technical Field

[0001] This utility model relates to the field of pipeline construction equipment, and in particular to a lifting device for indoor pipeline installation. Background Technology

[0002] Currently, in interior building construction, the installation of pipes near the roof, known as high-altitude pipe installation, is a common type of work. Common examples include fire-fighting pipe installation and water supply / drainage pipe installation. Because it requires lifting heavy pipes from the ground to the installation location, appropriate lifting and hoisting equipment is necessary.

[0003] Existing lifting devices primarily consist of a mobile platform installed on the indoor ground. A telescopic rod is mounted vertically on this platform, and its length is adjustable. During pipe lifting, the locking mechanism (e.g., a pin) ensures the stability of the telescopic rod's length, providing necessary support. A lifting rope is attached to the telescopic rod, with a hook at one end. In practice, the pipe is lifted from the ground using the hook until it reaches the desired installation height. However, because the mobile platform is not fixed to the indoor ground, and the total height of the telescopic rod is considerable, even slight swaying during pipe lifting can cause the lifting device to tip over, severely impacting construction safety and progress. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a lifting device for indoor pipe installation that prevents the lifting device from tipping over during pipe lifting.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a lifting device for indoor pipe installation, including a mobile platform set on the indoor ground, a telescopic rod set vertically on the mobile platform, a lifting rope set on the telescopic rod, a hook set at one end of the lifting rope, and a jacking mechanism, which is fixedly set on the telescopic rod. The jacking mechanism lifts the jacking rod upward until it is close to the indoor roof.

[0006] Furthermore, the lifting mechanism includes a jack, and a pad is provided between the jack's lifting rod and the roof.

[0007] Furthermore, the telescopic pole includes a telescopic main pole and a first telescopic pole, the first telescopic pole being telescopically mounted inside the telescopic main pole, and the telescopic main pole being fixedly mounted on the mobile platform.

[0008] Furthermore, the bottom of the mobile platform includes front wheels and rear wheels, and the extension line of the telescopic main rod is located between the front wheels and the rear wheels.

[0009] Furthermore, a first positioning pin is provided between the telescopic main rod and the first telescopic rod, which is used to fix the first telescopic rod to the telescopic main rod.

[0010] Furthermore, it includes a second telescopic rod, which is telescopically mounted inside the first telescopic rod. A crossbar is fixedly mounted on the top of the second telescopic rod, and a lifting mechanism is fixedly mounted on the crossbar.

[0011] Furthermore, a second positioning pin is provided between the first telescopic rod and the second telescopic rod, which is used to fix the second telescopic rod to the first telescopic rod.

[0012] Furthermore, rollers are installed on the crossbar, and a suspension rope is attached to the rollers, with one end of the suspension rope connected to a winch on the moving platform.

[0013] Furthermore, it includes a fixing device for securing the pipe to be hoisted, the fixing device including a pair of protective plates, the pipe being disposed between the protective plates, and hoisting strap shackles being disposed on the wall surface facing away from the protective plates, with hoisting straps disposed inside the hoisting strap shackles and the hoisting straps being disposed on the hooks.

[0014] Furthermore, a rubber pad is provided on the protective plate, and the rubber pad is placed between the pipe and the protective plate.

[0015] The beneficial effects of this utility model are as follows: In actual use, first determine the position of the mobile platform indoors, then adjust the length of the telescopic rod to the required height and lock it. Finally, raise the lifting rod of the jacking mechanism until it is flush with the indoor ceiling. At this point, the load-bearing unit composed of the mobile platform, telescopic rod, and jacking mechanism is firmly set between the indoor floor and the ceiling. Because the jacking rod is raised, the mobile platform is firmly pressed to the ground, while the jacking rod is firmly pressed against the ceiling surface, greatly increasing the frictional force exerted by the ceiling on the jacking rod and effectively preventing the lifting device from tipping over. This utility model is particularly suitable for indoor pipe installation operations. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1 to 7 The illustration shows an embodiment of a lifting device for indoor pipe installation. This lifting device is used in indoor pipe construction to safely and reliably lift pipe 121 from the ground to a height near the roof 91 for installation. A mobile platform 1 is located on the indoor floor and can be moved on the floor via rollers to adjust the lifting position of the pipe. The top surface of the mobile platform 1 is equipped with a lifting operation platform 7, a winch 6, and a telescopic main rod 2. The lifting operation platform 7 can be vertically adjusted to lift construction personnel to a higher position for pipe 121 installation and operation of the jacks 8. The telescopic main rod 2 is vertically oriented and its bottom is fixed to the top surface of the mobile platform 1. Based on the telescopic main rod 2, the first telescopic rod 3 is sleeved inside the telescopic main rod 2. The first telescopic rod 3 can slide up and down relative to the telescopic main rod 2 to adjust its height. When it is necessary to lock the height of the first telescopic rod 3 relative to the telescopic main rod 2, the first positioning pin is inserted into the hole between the telescopic main rod 2 and the first telescopic rod 3. Similarly, the second telescopic rod 4 can slide up and down relative to the first telescopic rod 3. When it is necessary to lock the height of the second telescopic rod 4 relative to the first telescopic rod 3, the second positioning pin is inserted into the hole between the second telescopic rod 4 and the first telescopic rod 3.

[0026] Through the height adjustment of the first telescopic rod 3 and the second telescopic rod 4, the crossbar 5 at the top of the second telescopic rod 4 is positioned close to the height of the roof 91. At this time, the jack 8 at the top of the crossbar 5 begins to lift. To prevent the lifting rod of the jack 8 from puncturing the roof 91, a pad 9, which can be a steel plate, can be added between the lifting rod and the roof 91 to protect the roof 91. As the lifting rod is lifted upward, it will be subjected to a reaction force from the roof 91. This reaction force is transmitted downward along the second telescopic rod 4, the first telescopic rod 3, and the telescopic main rod 2 to the moving platform 1, becoming a downward pressure that firmly presses the moving platform 1 to the ground. Thus, the entire lifting device is firmly fixed between the ground and the roof 91. Due to the friction between the roof 91 and the ground, the entire lifting device will be very stable, without swaying or tipping over. Generally, it is preferable that the extension line of the telescopic main rod 2 is positioned between the front and rear wheels of the moving platform 1 to further prevent swaying that may be caused by the sliding of the moving platform 1.

[0027] After completing the above-mentioned lifting and fixing, as follows: Figure 3 and Figure 5 As shown, one end of the lifting rope 10 is attached to the winch 6. After the lifting rope 10 is hooked onto the roller of the crossbar 5, the other end of the lifting rope 10 is fixedly connected to the hook 11. When the winch 6 rotates forward, the lifting rope 10 lifts the hook 11 upward. When the winch 6 rotates in reverse, the lifting rope 10 lowers the hook 11 downward. The roller of the crossbar 5 is used to allow the lifting rope 10 to move smoothly and reduce friction during its movement.

[0028] Figure 4 The diagram illustrates one embodiment of the fixing device, which includes paired protective plates 13, which can be steel or iron. A pipe 121 is positioned between the protective plates 13. Lifting strap shackles 15 are respectively installed on the opposite wall surfaces of the protective plates 13, each containing a lifting strap 12, which is mounted on a hook 11. Rubber pads 14 are installed on the protective plates 13, positioned between the pipe 121 and the protective plates 13. In actual use, when the hook 11 lifts upwards, it pulls up the lifting straps 12, causing the two opposing protective plates 13 to come together, thus clamping the pipe 121. Due to the protection of the rubber pads 14, the pipe 121 can be securely and safely clamped and lifted. After the lifting sling 12 passes through the lifting sling shackles 15 on both sides, a portion of the lifting sling 12 will be placed at the bottom of the two guard plates 13. This portion of the lifting sling 12 can provide support for the bottom of the pipe 121.

[0029] After lifting pipe 121 to a height close to the roof 91, and since the construction workers have already ascended to a height close to the roof 91 via the lifting platform 7, pipe 121 can be installed on the roof 91. Then, hook 11 moves downwards, lowering the fixing device to the ground, preparing for the lifting of the next pipe 121. After completing the work in the surrounding area, the construction workers first move the lifting rod of jack 8 downwards while removing the pad 9. Then, the moving platform 1 is slowly moved to the next installation position for pipe 121. Next, the lifting rod is moved upwards, and the pad 9 is secured to the roof 91, fixing the new installation position. Then, the lifting of the new pipe 121 can begin, continuing the installation process.
