Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude operation safety equipment, in particular to a high-altitude operation safety belt hanging point device at the edge of a balcony. Background Art

[0002] Balcony edge aerial work refers to aerial work that needs to be done on the balcony of a building, close to the edge or hanging over the edge. This type of work has a high safety risk because workers need to operate at high altitudes and are prone to slipping or falling accidentally. Balcony edge aerial work may involve cleaning, maintenance, decoration and other work, and strict safety measures need to be taken to protect the safety of workers. These measures include the use of safety belts, the installation of guardrails, and the provision of safety nets. Balcony edge aerial work requires special safety measures. The safety belt hanging point device is to ensure that workers can firmly fasten their safety belts when working at high altitudes to prevent accidental falls. High-strength materials are usually used and must undergo rigorous design and testing to ensure its stability and reliability under extreme conditions.

[0003] The distance of the safety belt is limited. Due to the different floor heights, the height of the balcony is also different. The construction position of some high balconies is low. At this time, due to the distance limitation of the safety belt, it is inconvenient for construction workers to carry out construction. Construction workers are required to use hanging baskets for construction, which makes construction more inconvenient. At the same time, since the safety hanging point is a fixed point and the balcony has a certain width, when it exceeds the distance of the safety belt, construction workers are required to re-hang the installation belt, which is time-consuming and labor-intensive, and reduces work efficiency.

The adjustment structure 2 includes an adjustment block 3, a threaded rod 4 and a first servo motor 5. The adjustment block 3 is slidably arranged inside the slide rail 1. A threaded hole is opened at one end of the adjustment block 3. The threaded hole at one end of the adjustment block 3 is threadedly connected with a threaded rod 4. When the threaded rod 4 rotates, it pushes the adjustment block 3 to move along the slide rail 1. The first servo motor 5 is arranged at one end of the threaded rod 4.

The upper surface of the second servo motor 12 is fixedly connected to the lower surface of the fixed plate 7. The fixed plate 7 is convenient for installing the second servo motor 12. The power output end of the second servo motor 12 is fixedly connected to one end of the worm 11. The second servo motor 12 is electrically connected to an external power supply. The second servo motor 12 is started, and the rotation of the power output end of the second servo motor 12 drives the worm 11 to rotate.

[0022] In the specific implementation process, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper surface and the lower surface of the slide rail 1 are respectively fixedly connected with a plurality of connecting plates 13, and the side surface of each group of connecting plates 13 is provided with fixing holes, and the fixing holes on the side surface of each group of connecting plates 13 are respectively provided with expansion bolts 14. When installing the slide rail 1, firstly, a plurality of mounting holes are drilled in the wall, and the expansion bolts 14 are screwed into the fixing holes on the side surfaces of the connecting plates 13 and the mounting holes on the wall, and then the slide rail 1 is tightly fixed to the wall, and the top and the bottom of the slide rail 1 are provided with sliding grooves, and the inner wall of the slide rail 1 is fixedly connected with a partition 21, and the side surface of the partition 21 is provided with through holes.

The sliding plates 15 on the upper surface and the lower surface of the adjustment block 3 are respectively slidably set inside the top and bottom sliding grooves in the slide rail 1. The sliding plates 15 limit the adjustment block 3 inside the slide rail 1 without hindering the sliding block from sliding along the slide rail 1. One side of the adjustment block 3 is fixedly connected to the end of the support arm 6 close to the slide rail 1. When the adjustment block 3 slides, it can drive the support arm 6 to move.

[0024] Among them, one end of the threaded rod 4 close to the first servo motor 5 passes through the through hole on the side surface of the partition 21 and is fixedly connected to the power output end of the first servo motor 5. One side of the first servo motor 5 is fixedly connected to the inner wall of the slide rail 1. The end of the threaded rod 4 away from the first servo motor 5 is rotatably connected to the inner wall of the slide rail 1. The first servo motor 5 is electrically connected to an external power supply. When the first servo motor 5 is started, the rotation of the power output end of the first servo motor 5 drives the threaded rod 4 to rotate inside the through hole on the side surface of the partition 21.

[0025] Among them, a groove is opened on the lower surface of the end of the support arm 6 away from the slide rail 1, and a pulley 16 is rotatably arranged inside the groove. The two ends of the pulley 16 are rotatably connected to the inner walls of the groove on the lower surface of the end of the support arm 6 away from the slide rail 1, and the pulley 16 can rotate inside the groove on the lower surface of the end of the support arm 6 away from the slide rail 1.

[0026] Among them, two groups of first mounting plates 17 and two groups of second mounting plates 18 are fixedly connected to the lower surface of the fixing plate 7, and through holes are opened on the lower end side surfaces of the two groups of first mounting plates 17 and the two groups of second mounting plates 18, and the winding rod 9 is rotatably connected to the inside of the through holes on the lower end side surfaces of the two groups of first mounting plates 17, and the winding rod 9 can rotate inside the through holes on the lower end side surfaces of the two groups of first mounting plates 17. An adjusting belt 19 is fixedly connected to the outer surface of the winding rod 9, and part of the adjusting belt 19 is wrapped around the outer surface of the winding rod 9. The outer surface of the adjusting belt 19 is attached to the outer surface of the pulley 16, and the pulley 16 reduces the wear of the adjusting belt 19 and increases the service life of the adjusting belt 19. The end of the adjusting belt 19 away from the winding rod 9 is fixedly connected to a connecting ring 20, and the connecting ring 20 is convenient for fixing and connecting the safety belt, and the worm 11 is rotatably connected to the inside of the through holes on the lower end side surfaces of the two groups of second mounting plates 18, and the worm 11 can rotate inside the through holes on the lower end side surfaces of the two groups of second mounting plates 18.

[0027] The working principle provided by the utility model is as follows: the operator first locks the safety belt in the connecting ring 20. When the operator needs to work on the balcony edge and the working position is low, the operator starts the second servo motor 12. The power output end of the second servo motor 12 rotates to drive the worm 11 to rotate. When the worm 11 rotates, it meshes with the worm wheel 10 and drives the worm wheel 10 to rotate. When the worm wheel 10 rotates, it drives the winding rod 9 to rotate. When the winding rod 9 rotates, the adjusting belt 19 is gradually released. The adjusting belt 19 increases the length of the safety belt, which is convenient for the operator to descend. The operator can work at a lower point. When the operator needs to return to the balcony, he only needs to control the power output end of the second servo motor 12 to reverse. At the same time, when the operator needs to adjust the working position, the operator starts the first servo motor 5. The rotation of the power output end of the first servo motor 5 drives the threaded rod 4 to rotate inside the through hole on the side surface of the partition 21. While the threaded rod 4 rotates, it is threadedly connected with the threaded hole at one end of the adjusting block 3, so that the adjusting block 3 slides inside the slide rail 1. The sliding of the adjusting block 3 drives the support arm 6 and the fixed plate 7 to move at the same time, which is convenient for adjusting the working position of the operator.
