Description

Technical Field

[0001] The utility model relates to the technical field of aerial work, and specifically relates to a portable aerial safety belt hanging device. Background Technique

[0002] Aerial work refers to work carried out by people at positions more than 2 meters above the reference plane of the falling height. Such work is particularly common in industries such as electricity, construction, and communication, including substation maintenance, tower erection, glass curtain wall cleaning, etc. Aerial work is extremely risky. Once a fall occurs, the consequences are unimaginable. Therefore, aerial work not only requires operators to have professional skills and knowledge, but also requires the use of a series of safety equipment to ensure personnel safety. The safety belt hanging device is one of the safety equipment in aerial work, which ensures the safety of workers.

[0003] A Chinese patent with the publication number CN212998047U discloses a portable aerial safety belt hanging device, including a hanging rod. One end of the hanging rod is provided with a hanging mechanism, and the other end is provided with a hanging part for hanging the safety belt; the hanging mechanism includes a hanging plate. The two ends of the hanging plate extend horizontally outwards to form hanging parts. The hanging plate is hinged to the end of the hanging rod corresponding to the two hanging parts. A support block for supporting the hanging plate is arranged outside the end of the hanging rod where the hanging plate is hinged. When the hanging plate rotates to be perpendicular to the hanging rod, one side of the hanging plate can abut against the support block; a torsion spring mechanism is also arranged between the hanging plate and the hanging rod. Under the torsion of the torsion spring mechanism, the hanging plate can rotate to a position perpendicular to the hanging rod.

[0004] Although the above solution provides safety guarantee and convenience for aerial work, the torsion spring mechanism may lose its original torsion due to fatigue or corrosion during long-term use, resulting in the hanging plate being unable to stably maintain a vertical position or requiring excessive force to rotate, increasing safety risks. Therefore, it does not meet the existing requirements. For this reason, we propose a portable aerial safety belt hanging device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a portable aerial safety belt hanging device to solve the problem that the torsion spring of the portable aerial safety belt hanging device is prone to fatigue and corrosion during use, affecting the stability of the hanging plate, thereby increasing the operation difficulty and safety risks as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A portable aerial safety belt hanging device, including an adjustment seat. A hanging rod is arranged at the lower end of the adjustment seat, and a hanging part is arranged at the lower end of the hanging rod.

[0007] It further includes a first transmission cavity which is opened at the lower side inside the adjusting seat. Four threaded rods which are annularly and equidistantly distributed are rotatably arranged at the upper side inside the first transmission cavity. Moving blocks are all threadedly connected to the outer sides of the threaded rods. Hanging blocks are all welded to the outer sides of the moving blocks. One ends of the hanging blocks all extend to the outside of the first transmission cavity, and the hanging blocks are all slidably matched with the first transmission cavity.

[0008] It further includes a second transmission cavity which is opened at the upper side inside the adjusting seat. Slide rods are installed at the four corners inside the second transmission cavity. A lifting plate is arranged inside the second transmission cavity. The slide rods all penetrate through the lifting plate, and the slide rods are all slidably matched with the lifting plate. A rotating rod is rotatably arranged at the middle position inside the first transmission cavity. One ends of the rotating rod all penetrate through and extend to the inside of the second transmission cavity, and the rotating rod is rotatably matched with the second transmission cavity.

[0009] Preferably, a first bevel gear is arranged on the outer wall of one end of the rotating rod inside the first transmission cavity. Second bevel gears are all arranged at one ends of the threaded rods, and the second bevel gears are all meshed and connected with the first bevel gear.

[0010] Preferably, guide rods are all welded below the threaded rods. The guide rods all penetrate through the moving blocks, and the guide rods are all slidably matched with the moving blocks.

[0011] Preferably, a rectangular block is arranged at one end of the rotating rod inside the second transmission cavity. A rotating block is arranged at the middle position inside the lifting plate, and the groove at the lower end of the rotating block is adapted to the rectangular block. The rotating block is connected to the lifting plate through a bearing.

[0012] Preferably, a connecting rod is adhesively fixed to the upper end of the rotating block. One end of the connecting rod extends to the outside of the second transmission cavity. A knob is installed at one end of the connecting rod outside the second transmission cavity.

[0013] Preferably, return springs are all sleeved on the lower sides of the slide rods. One ends of the return springs are all connected to the lifting plate, and the other ends of the return springs are all connected to the second transmission cavity.

[0014] Preferably, a connecting plate is threadedly connected to the outer wall of the hanging rod. An annular rubber block is adhesively fixed to the upper end of the connecting plate.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. The utility model opens a first transmission cavity on the lower side inside the adjusting seat. After the adjusting seat passes through the air conditioner installation hole, the rotating rod in the first transmission cavity is rotated. Through the meshing connection of the first bevel gear and the second bevel gear, the four threaded rods can be rotated synchronously. The threaded rods will drive the hanging blocks to move horizontally in a straight line, so that the four hanging blocks can be unfolded outward. The synchronous outward unfolding of the four hanging blocks can more evenly disperse the weight and vibration of the worker, enhance the stability and safety of high-altitude operations, and reduce the risk of loosening or damage caused by uneven single-point stress. By adopting the mechanical transmission mode of the threaded rods and the hanging blocks, the problems of fatigue and corrosion that may occur to the torsion spring due to long-term use are avoided, thus ensuring the stability of the hanging part and reducing the safety risk brought by the instability of the hanging plate.

[0017] 2. The utility model opens a second transmission cavity on the upper side inside the adjusting seat. When the rotating rod needs to be rotated, only need to press the knob downward and rotate it. The knob will make the rotating block rotate through the connecting rod. The downward movement of the knob will make the rectangular block snap into the groove below the rotating block. Then, when rotating, it can drive the rectangular block to make the rotating rod rotate synchronously. After adjustment, the lifting plate will move upward under the elasticity of the reset spring, so that the rectangular block can be separated from the rotating block, thus avoiding the rotation caused by external accidental touch, ensuring the stability of the adjusted hanging block, and making the use safer.

[0018] 3. The utility model has a connecting plate threadedly connected to the outer wall of the hanging rod, and an annular rubber block is adhesively fixed to the upper end of the connecting plate. After the adjusting seat is installed on the upper side of the air conditioner installation hole, the connecting plate can be rotated to make the annular rubber block snap into the inside of the air conditioner installation hole. When the annular rubber block is in close fit with the air conditioner installation hole, the connection stability between the hanging rod and the air conditioner installation hole is increased through the friction force, making the whole device more stable and reliable after installation and not easy to loosen or fall off.

Detailed implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-5 , the present invention provides a technical solution: a portable high-altitude safety belt hanging device, including an adjusting seat 1, a hanging rod 2 is arranged at the lower end of the adjusting seat 1, and a hanging part 3 is arranged at the lower end of the hanging rod 2;

[0027] It further includes a first transmission cavity 4, which is opened at the lower side inside the adjusting seat 1. Four threaded rods 5 are rotatably arranged at equal intervals in a ring at the upper side inside the first transmission cavity 4. Moving blocks 7 are threadedly connected to the outside of the threaded rods 5. Hanging blocks 11 are welded to the outside of the moving blocks 7. One ends of the hanging blocks 11 all extend to the outside of the first transmission cavity 4, and the hanging blocks 11 are all slidably matched with the first transmission cavity 4;

[0028] It further includes a second transmission cavity 12, which is opened at the upper side inside the adjusting seat 1. Sliding rods 14 are installed at the four corners inside the second transmission cavity 12. A lifting plate 16 is arranged inside the second transmission cavity 12. The sliding rods 14 all penetrate through the lifting plate 16, and the sliding rods 14 are all slidably matched with the lifting plate 16. A rotating rod 9 is rotatably arranged at the middle position inside the first transmission cavity 4. One end of the rotating rod 9 all penetrates and extends to the inside of the second transmission cavity 12, and the rotating rod 9 is rotatably matched with the second transmission cavity 12.

[0029] During use, the adjustment base 1 passes through the air conditioner installation hole. Operate the knob 20, drive the lifting plate 16 to compress the return spring 15 through the connecting rod 18, drive the rotating block 17 to make the rectangular block 13 snap in and rotate with it. This rotation drives the rotation of the threaded rod 5 through the meshing of the first bevel gear 8 and the four second bevel gears 10, and then the moving block 7 moves horizontally along the guide rod 6 to expand the hanging block 11, achieving stable hanging. This design avoids the problem of long-term use of torsion springs and improves the stability of the hanging part 3. After loosening the knob 20, the return spring 15 resets, separating the rotating block 17 from the rectangular block 13, preventing accidental touch and improving safety.

[0030] Please refer to Figure 3 and Figure 5 , on the outer wall of one end of the rotating rod 9 located inside the first transmission cavity 4, a first bevel gear 8 is provided. One end of each threaded rod 5 is provided with a second bevel gear 10, and the second bevel gears 10 are all meshed and connected with the first bevel gear 8. Through the meshing connection of the second bevel gear 10 and the first bevel gear 8, it can ensure that the rotational force of the rotating rod 9 is evenly transmitted to the four threaded rods 5 to achieve synchronous rotation, thereby ensuring that the four hanging blocks 11 can expand evenly and synchronously, improving the accuracy and stability of adjustment;

[0031] Please refer to Figure 5 , below each threaded rod 5, a guide rod 6 is welded. The guide rods 6 all penetrate the moving block 7, and the guide rods 6 are all slidably matched with the moving block 7. The guide rods 6 provide a stable axial movement trajectory for the moving block 7, preventing it from shifting or shaking during rotation, and ensuring the smoothness and accuracy of the horizontal movement of the moving block 7 and the hanging block 11;

[0032] Please refer to Figure 4 and Figure 5 , at one end of the rotating rod 9 located inside the second transmission cavity 12, a rectangular block 13 is provided. At the middle position inside the lifting plate 16, a rotating block 17 is provided, and the groove at the lower end of the rotating block 17 is adapted to the rectangular block 13. The rotating block 17 and the lifting plate 16 are connected by a bearing 19. The introduction of the bearing 19 reduces the friction between the rotating block 17 and the lifting plate 16, making the rotation smoother. The cooperation between the rectangular block 13 and the groove of the rotating block 17 ensures the reliable connection and synchronous rotation between the two, providing a solid foundation for the entire transmission mechanism;

[0033] Please refer to Figure 1 , Figure 2 and Figure 5, a connecting rod 18 is adhesively fixed to the upper end of the rotating block 17. One end of the connecting rod 18 extends outside the second transmission cavity 12. A knob 20 is installed at the end of the connecting rod 18 located outside the second transmission cavity 12. The design of the knob 20 enables workers to conveniently control the operation of the internal transmission mechanism through external operations. The connecting rod 18 serves as a bridge for force transmission, transmitting the rotational force of the knob 20 to the rotating block 17, thereby driving the entire transmission mechanism to work, achieving the convenience and efficiency of operation;

[0034] Please refer to Figure 5 , return springs 15 are sleeved on the lower sides of the outer parts of the sliding rods 14. One ends of the return springs 15 are connected to the lifting plate 16, and the other ends of the return springs 15 are connected to the second transmission cavity 12. The return springs 15 can automatically recover their deformation after the worker releases the knob 20, thereby driving the lifting plate 16 and the rotating block 17 to reset, so that the rectangular block 13 is separated from the rotating block 17, avoiding accidental rotation caused by accidentally touching the knob 20, and improving the safety and stability of the equipment;

[0035] Please refer to Figure 1 and Figure 2 , a connecting plate 21 is threadedly connected to the outer wall of the hanging rod 2. An annular rubber block 22 is adhesively fixed to the upper end of the connecting plate 21. The softness and elasticity of the annular rubber block 22 can ensure a tight fit with the air conditioner installation hole, increasing the friction force and improving the connection stability between the hanging rod 2 and the installation hole.

[0036] Working principle: When in use, pass the adjusting base 1 through the air conditioner installation hole, press the knob 20. The knob 20 drives the lifting plate 16 to move towards the direction of the rectangular block 13 through the connecting rod 18, which will compress the return spring 15. The lifting plate 16 will drive the rotating block 17 to move synchronously, so that the rectangular block 13 is clamped into the groove at the lower end of the rotating block 17. At this time, the knob 20 can be rotated, and the rotating block 17 can rotate smoothly through the bearing 19. The rotating block 17 will drive the rectangular block 13 to rotate synchronously. The rectangular block 13 will drive the first bevel gear 8 to rotate through the rotating rod 9. Since the first bevel gear 8 is meshed with the four second bevel gears 10, it will drive the second bevel gears 10 to rotate the threaded rod 5 synchronously. The threaded rod 5 will drive the moving block 7 to rotate synchronously. Since the lower ends of the moving blocks 7 are all slidably matched with the guide rods 6, the moving blocks 7 will all be axially limited. The rotation of the moving blocks 7 will be converted into horizontal linear movement. The moving blocks 7 will drive the hanging blocks 11 to extend out of the interior of the first transmission cavity 4, realizing the expansion of the four hanging blocks 11. By adopting the mechanical transmission mode of the threaded rod 5 and the hanging blocks 11, it avoids the fatigue and corrosion problems that may occur to the torsion spring due to long-term use, thus ensuring the stability of the hanging part 3, reducing the safety risks brought by the instability of the hanging plate. After the adjustment is completed, the knob 20 can be released, and the position of the lifting plate 16 will be restored under the elastic recovery action of the return spring 15, so as to drive the rotating block 17 to separate from the rectangular block 13, so that the synchronous rotation of the rectangular block 13 will not be realized when the knob 20 is accidentally touched, ensuring the stability of the adjusted hanging blocks 11. By rotating the connecting plate 21, the annular rubber block 22 can be clamped into the lower end of the air conditioner installation hole. When the annular rubber block 22 is in close fit with the air conditioner installation hole, the connection stability between the hanging rod 2 and the air conditioner installation hole is increased through the friction force, making the whole device more stable and reliable after installation, not easy to loosen or fall off.
