Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, specifically a high-altitude fall net with a tightening structure. Background Technology

[0002] Construction engineering refers to the actual construction and installation process in various engineering projects such as buildings, roads, bridges, and tunnels, according to design plans and construction drawings. During construction, fall protection nets are usually installed to prevent people and objects from falling or to avoid or reduce injuries from falling objects. However, existing fall protection nets still have certain defects in use, such as:

[0003] After being left in place for a long time, the safety nets of high-altitude fall protection nets will have insufficient tension and will not be able to provide enough support. Most existing high-altitude fall protection nets do not have a tightening structure, and the support frame of most existing high-altitude fall protection nets is directly installed to the bracket. When subjected to heavy objects, the connecting bolts will loosen due to the impact force, thus causing damage. There are also problems such as the lack of a buffer structure. Utility Model Content

[0004] The purpose of this invention is to provide a high-altitude fall net with a tightening structure, in order to solve the problems mentioned in the background art that the current high-altitude fall nets on the market do not have a tightening structure and a cushioning structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-altitude fall net with a tightening structure, comprising: a support frame, a protective net, and an installation plate;

[0006] A protective net is installed inside the support frame, and an installation plate is installed on the back of the support frame, with the protective net serving as the protective base.

[0007] The tensioning mechanism is installed inside the support frame. The tensioning mechanism includes: a hook, a pull rope, a rotating rod, a sleeve, a bolt, and an arc-shaped extrusion plate. The protective net is hung with a hook, and a pull rope is fixedly connected to the hook.

[0008] Preferably, a rotating rod is rotatably connected through the inner wall of the support frame, and a pull rope is wound around the rotating rod.

[0009] Preferably, a sleeve is fixedly connected to one side of the support frame, and the sleeve is sleeved on the rotating rod.

[0010] Preferably, the sleeve is internally threaded with a bolt, and the end of the bolt is rotatably connected to an arc-shaped extrusion plate, which is disposed on the outer circumferential surface of the rotating rod.

[0011] Preferably, a damper is fixedly connected to the back of the support frame, and the damper is fixedly connected to the front of the mounting plate.

[0012] Preferably, a buffer spring is sleeved on the damper, the buffer spring is connected to the front of the mounting plate, and the buffer spring is connected to the back of the support frame.

[0013] Preferably, a U-shaped friction rod is fixedly connected to the front of the mounting plate, a first lug is connected to the U-shaped friction rod, a transmission plate is rotatably connected inside the first lug, the other end of the transmission plate is rotatably connected inside a second lug, and the second lug is fixedly connected to the back of the support frame.

[0014] Preferably, a return spring is connected to one side of the first ear, and the return spring is sleeved on the U-shaped friction rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By loosening the bolts with a wrench, and then rotating the rotating rod to wind the rope and tighten the protective net, the bolts are then tightened with a wrench to move the arc-shaped extrusion plate, which in turn squeezes the rotating rod and tightens it. When the protective net receives a heavy object, the protective net pulls the support frame to move the extrusion damper and buffer spring, and at the same time pushes the second ear, causing the transmission plate to rotate between the first and second ears, and pushes the first ear to move along the U-shaped friction rod to extrude the return spring, converting the impact force into internal energy and friction force for consumption. Then the buffer spring and return spring reset the support frame and the first ear, restoring the damper, and thus buffering the impact. The specific details are as follows:

[0016] 1. Loosen the bolts with a wrench to move the arc-shaped extrusion plate away from the rotating rod, rotate the rotating rod to wind the rope, pull the protective net to tighten it, and then tighten the bolts with a wrench to move the arc-shaped extrusion plate to squeeze the rotating rod and tighten it.

[0017] 2. When the protective net receives a heavy object, the net first deforms to buffer the impact. Then, it pulls the support frame to move the damper and buffer spring, while simultaneously pushing the second lug, which moves the first lug along the U-shaped friction rod to squeeze the reset spring. This converts the impact force into internal energy and friction force for dissipation. Then, the buffer spring and reset spring deform to reset the support frame and the first lug, restoring the damper to its original state, thus providing buffering. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a high-altitude fall net with a tightening structure, comprising: a support frame 1, a protective net 2, and an installation plate 3;

[0026] A protective net 2 is installed inside the support frame 1, and an installation plate 3 is installed on the back of the support frame 1, with the protective net 2 serving as the protective base; a tensioning mechanism 4 is installed inside the support frame 1, and the tensioning mechanism 4 includes: a hook 401, a pull rope 402, a rotating rod 403, a sleeve 404, a bolt 405, and an arc-shaped extrusion plate 406. The hook 401 is hung inside the protective net 2, and the pull rope 402 is fixedly connected to the hook 401.

[0027] A rotating rod 403 is rotatably connected through the inner wall of the support frame 1. A pull rope 402 is wound around the rotating rod 403. Rotating the rotating rod 403 winds the pull rope 402, pulling the protective net 2 and tightening it. A sleeve 404 is fixedly connected to one side of the support frame 1. The sleeve 404 is fitted onto the rotating rod 403, allowing the rotating rod 403 to rotatably connect inside the sleeve 404. A bolt 405 is threaded through the sleeve 404. An arc-shaped pressing plate 406 is rotatably connected to the end of the bolt 405. The arc-shaped pressing plate 406 is set on the outer circumference of the rotating rod 403. Rotating the bolt 405 moves the arc-shaped pressing plate 406, pressing the rotating rod 403 to prevent rotation.

[0028] A damper 5 is fixedly connected to the back of the support frame 1. The damper 5 is fixedly connected to the front of the mounting plate 3. When the protective net 2 is subjected to impact, it causes the support frame 1 to squeeze the damper 5, converting the impact force into internal energy. A buffer spring 6 is sleeved on the damper 5. The buffer spring 6 is connected to the front of the mounting plate 3 and the back of the support frame 1. The support frame 1 squeezes the buffer spring 6 while squeezing the damper 5. Then the buffer spring 6 resets the support frame 1 and restores the damper 5. A U-shaped friction rod 7 is fixedly connected to the front of the mounting plate 3. A first lug 8 is connected to the U-shaped friction rod 7. A transmission plate 9 is rotatably connected inside the first lug 8. The other end of the transmission plate 9 is rotatably connected to the second ear 10. The second ear 10 is fixedly connected to the back of the support frame 1. When the support frame 1 compresses the damper 5, it drives the second ear 10 to move downward, causing the transmission plate 9 to rotate between the first ear 8 and the second ear 10, and pushes the first ear 8 to move along the U-shaped friction rod 7, converting the impact force into friction force for consumption. A return spring 11 is connected to one side of the first ear 8. The return spring 11 is sleeved on the U-shaped friction rod 7. When the first ear 8 moves along the U-shaped friction rod 7, it compresses the return spring 11. When the impact force disappears, the return spring 11 resets the first ear 8.

[0029] In conclusion: Figure 1-4 As shown, when using this type of fall net with a tightening structure, a simple understanding of the device is provided. First, use a fixing bolt to pass through the hole on the mounting plate 3 to fix the mounting plate 3 in place. Open the hook 401 to hook the protective net 2. When the tension is insufficient after a long period of inactivity, use a wrench to loosen the bolt 405 to move the arc-shaped compression plate 406 away from the rotating rod 403. Rotate the rotating rod 403 to wind the pull rope 402, pull the protective net 2, and tighten the protective net 2. Then, use a wrench to tighten the bolt 405 to move the arc-shaped compression plate 406 and squeeze the rotating rod 403. When the protective net 2 receives a heavy object... The protective net 2 first deforms to buffer the impact, then pulls the support frame 1 to move the damper 5 and the buffer spring 6, converting the impact force into internal energy for dissipation. At the same time, it pushes the second lug 10, causing the transmission plate 9 to rotate between the first lug 8 and the second lug 10, and pushes the first lug 8 to move along the U-shaped friction rod 7 to squeeze the reset spring 11, converting the impact force into friction for dissipation. Then the buffer spring 6 and the reset spring 11 deform to reset the support frame 1 and the first lug 8, restoring the damper 5 to its original state. The contents not described in detail in this description are existing technologies known to those skilled in the art.
