Description

Technical Field

[0001] The invention relates to the technical field of personal safety equipment, in particular to a high-altitude operation anti-fall safety rope system. Background Art

[0002] With the rapid development of modern construction and industry, aerial work has become an indispensable part of various engineering projects. However, the safety issues of aerial work have become increasingly prominent, especially the anti-fall safety rope system as a key equipment to protect the life safety of workers. Its performance and adaptability are directly related to the safety and efficiency of the operation process.

[0003] The existing anti-fall safety rope technology has the following limitations: 1. Poor environmental adaptability. Most of the anti-fall safety rope systems on the market are relatively simple in design and difficult to adapt to the complex and changeable high-altitude working environment. For example, under extreme conditions such as strong wind, drastic temperature changes, and high humidity, the material and performance of traditional safety ropes may be affected, resulting in reduced safety performance. In addition, for working areas with special shapes or structures, such as curved surfaces and inclined surfaces, the existing safety rope systems are often difficult to effectively fix and install, limiting their scope of application. 2. Difficult installation. In high-altitude operations, the installation position of the safety rope often needs to be adjusted according to actual conditions, but in the existing technology, the installation of the safety rope often relies on manual operation, which is not only time-consuming and labor-intensive, but also has great safety hazards. Especially when working in a small space or complex structure at high altitude, the difficulty of installation is doubled. 3. Single function. The traditional anti-fall safety rope system mainly focuses on preventing operators from falling, but in the actual operation process, they may also face various safety risks such as object impact and electric shock. However, the existing safety rope system often only has a single anti-fall function and cannot fully guarantee the safety of operators. 4. Short service life. Due to the complex and changeable environment of high-altitude working, the safety rope is easily damaged by wear and corrosion during use, which shortens its service life. At the same time, the maintenance and replacement of traditional safety ropes are also cumbersome, increasing operating costs and safety risks. Summary of the invention

DETAILED DESCRIPTION

[0018] Example: like Figure 1-10 As shown in the figure, a high-altitude work anti-fall safety rope system includes an energy feedback module 2. The safety rope 6 is led out from the energy feedback module 2 and passes through multiple intermediate adapter modules along the working path and then is fixed at the other end. The intermediate adapter modules support the safety rope 6 in the middle and corner parts according to the shape of the working path. The safety rope 6 is used to hang the connecting rope of the operator. An energy feedback connector 21 is provided on the energy feedback module 2. One end of the energy feedback connector 21 is fixed and the other end is tensioned and connected with the safety rope 6. A plurality of S-shaped buffer plates 22 are provided between the two ends of the energy feedback connector 21.

[0019] The safety rope 6 is led out from the energy feeding module 2 and passes through a plurality of intermediate transfer modules along the operation path, and then the other end is fixedly connected to another energy feeding module 2 .

[0020] like Figure 1 As shown in the figure, multiple S-shaped plates are connected in sequence in the buffer plate 22 on the energy feeding module 2. The axial distance when the plates are contracted together is shortened through the S-shaped path and elastic potential energy can be stored, which is used to cushion the operator when he accidentally slips and falls. The displacement of the safety rope 6 during the fall is supplemented by stretching the S-shaped plate.

[0021] The above-mentioned intermediate transfer module types include an intermediate bracket 3 , a corner bracket 4 and a top rotating bracket 5 .

[0022] A base 8 is provided at the bottom of the energy feeding module 2, the middle bracket 3, the corner bracket 4 and the top rotating bracket 5, and the base 8 is used to be connected to the working surface.

[0023] The intermediate support 3 includes a fixed support 9 connected to the base 8, a support frame 31 is provided on the fixed support 9, a cable support tube 32 is provided on the top of the support frame 31, and the safety cable 6 passes through the cable support tube 32; The corner bracket 4 includes a fixed bracket 9 connected to the base 8, a corner support frame 41 is provided on the fixed bracket 9, a corner support tube 42 is provided on the top of the corner support frame 41, and the corner support tube 42 is provided with an arc-shaped tube body for converting the angle of the plane cable, and the safety rope 6 passes through the corner support tube 42; The top rotation bracket 5 includes a fixed bracket 9 connected to the base 8, on which a top rotation support frame 51 is provided. A top rotation support tube 52 is provided on the top of the top rotation support frame 51. The top rotation support tube 52 is provided with an arched or concave tube body for converting the angles of the upper and lower ropes, and the safety rope 6 passes through the top rotation support tube 52.

[0024] A support column 10 is provided at the outlet of the safety cable 6 of the energy feeding module 2 and at the inlet and outlet of the intermediate transfer module. A wire routing wheel 11 is provided at the top of the support column 10 , and the wheel groove of the wire routing wheel 11 faces the safety cable 6 .

[0025] The wire wheel 11 is used to roll and cushion the wire entry and exit points when the safety wire 6 is deformed due to the pulling of the fall when an operator falls, so as to prevent the deformation from being transmitted to the entry or exit point and rubbing against the supporting tube body, causing the wire of the safety wire 6 to tear and then cause the rope to break.

[0026] A wire-routing pressure sensor 12 is provided at the shaft of the wire-routing wheel 11 , and the wire-routing pressure sensor 12 is used to detect whether a fall occurs and the fall position.

[0027] During normal operation, the safety rope 6 is pre-tightened. Although the safety rope with the operator hanging on it is under stress, the force of the safety rope is less than the pre-tightening force, and the safety rope 6 is in a straight state. At this time, the safety rope 6 is not in contact with the wiring wheel 11 or is in slight contact with it. The wiring pressure sensor 12 has no pressure value or a very small value. When a person falls, the impact force of the person falling is very large, causing the safety rope 6 to deform and then contact the wiring wheel 11, causing the pressure value of the wiring pressure sensor 12 to increase sharply. It is possible to judge whether a person has fallen based on the pressure value, and the specific position of the person falling can be judged by the position of the wiring wheel 11 where the pressure increases.

[0028] The above-mentioned support column 10 and the cable wheel 11 are respectively arranged one on both sides of the safety rope 6.

[0029] By providing a routing wheel 11 on each side of the safety rope 6, in addition to preventing the safety rope 6 from being torn due to workers falling from the eaves, it can also prevent the rope from being torn from both sides due to falling caused by rust on the roof or excessive load.

[0030] The above-mentioned energy feedback connector 21 is connected to the safety rope 6 through a wire tensioner 7. The wire tensioner 7 includes a connecting plate 71 connected to the energy feedback connector 21. The connecting plate 71 is connected to one end of the expansion sleeve 72. The safety rope 6 enters the sleeve from the other end of the expansion sleeve 72. An adjusting nut 74 is provided between the connecting plate 71 and the expansion sleeve 72. One end of the adjusting nut 74 is threadedly connected to the inner side of the rotating nut 73 at the top of the expansion sleeve 72. The safety rope 6 is fixed by adjusting the tensioning force by rotating the adjusting nut 74 to enter the expansion sleeve 72 to a depth.

[0031] In the preferred scheme, the above-mentioned energy feedback connector 21 is connected to the U-shaped bushing 13, and a pad 14 is provided between the upper and lower ports of the U-shaped bushing 13 for fixing. A tensioning adjustment nail 15 is provided at the U-shaped bottom of the U-shaped bushing 13, and the end of the tensioning adjustment nail 15 passes through the U-shaped bushing 13 and is connected to the adapter rod 18. A pre-tightening pressure sensor 16 is provided on the tightening side of the tensioning adjustment nail 15 on the inner side of the U-shaped bushing 13, and the protruding end of the tensioning adjustment nail 15 on the outer side of the U-shaped bushing 13 is threadedly connected to the pre-tightening screw 17, and the other end of the adapter rod 18 is connected to the safety rope 6, and a quick-spin hole 19 is provided on the adapter rod 18.

[0032] By adjusting the pre-tightening screw 17, the tensioning adjustment pin 15 is tightened to compress the pre-tightening pressure sensor 16 to achieve the pre-tightening force. When a person falls, the safety rope 6 is displaced to act on the tensioning adjustment pin 15, so that the detection value of the pre-tightening pressure sensor 16 increases. The detection value of the pre-tightening pressure sensor 16 can be used to confirm the detection of the person falling by the routing pressure sensor 12 to prevent misjudgment.

[0033] like Fig.10 As shown in the figure, the middle bracket 3 is used to support the safety rope 6 of multiple lengths, the corner bracket 4 is used to support the safety rope 6 at the corner, the top rotating bracket 5 is used to connect the two sides of the roof or the concave connection, the bottom of the base 8 of the top rotating bracket 5 matches the roof, and the system is installed on the outside of the roof to ensure the safety of people falling.
