[0025] The following is combined with Figure 1-4 The present invention is described in further detail.

[0026] The embodiment of the present invention discloses a safety rope suspension and corner protection device.

[0027] Reference Figures 1-4 A safety rope hanging and corner protection device includes a hanging rope 8, an arc-shaped member, and a rope tightener 8. The arc-shaped member is set at the corner of the tied structure 10. The arc-shaped member has a mounting hole 5 and a tightening rope hole 4 for the hanging rope 8 to pass through. The hanging rope 8 includes a hanging rope 8- and a hanging rope 8-2. The hanging rope 8- and the hanging rope 8-2 are respectively wound around the two sides of the tied structure 10 through the corresponding mounting hole 5 of the arc-shaped member, and then pass through the tightening rope hole 4 and are fixed by the rope tightener 8. The rope tightener 8 and the anti-slip member 3 increase the friction with the tied structure 10 to ensure that the safety rope 9 is firmly tied. It is easy to install and use, and has the functions of a corner protector and a hanging point, and has strong applicability.

[0028] The arc-shaped member has a rotating part that enables the arc angle of the arc-shaped member to open or contract. An elastic member 2 is provided inside the arc-shaped member. The elastic member 2 is used to drive the arc portion to expand outward, thereby maintaining the tension of the suspension rope 8, ensuring the friction between the bound structure 10, the arc-shaped member and the suspension rope 8, and improving the suspension stability of the suspension rope 8. It is easy to install and remove, safe and reliable, does not damage the structure, and has the functions of corner protection and suspension point setting.

[0029] The arc-shaped part is provided with a limit column 6 for rotation, and the arc-shaped part is provided with a limit portion. The rotation axis of the limit column 6 is provided with a coil spring. Under the action of the coil spring, the limit column 6 rotates and contacts the limit portion to form a limit. The limit column 6 can rotate inward, and the suspension rope 8 is installed in the installation hole 5 of the arc-shaped part through the limit column 6. The limit column 6 is divided into upper and lower parts. The upper limit column 6 can be pressed and rebounded, and the lower limit column 6 is fixedly set as the limit portion. The rope is directly put in from here, which is convenient for rope hanging. A tooth connection design is provided between the upper limit column 6 and the lower limit column 6 to prevent the buckle from popping out.

[0030] Arc-shaped portions are provided on the inner and outer sides of the corners of the mounting hole 5 to improve the passability of the suspension rope 8, avoid the corners from being cut, and improve safety.

[0031] An anti-slip part 3 is provided on the inner side of the arc-shaped part. The anti-slip part 3 is used to be in close contact with the bound structure 10. The inside of the arc-shaped part has a mounting hole 5 for the suspension rope 8 to pass through. The friction is enhanced after being tightened by the rope tightener 8 to prevent the arc-shaped part from sliding. The anti-slip part 3 is made of anti-slip rubber. The arc-shaped part and the bound structure 10 are in contact with the anti-slip rubber to increase the friction.

[0032] A protrusion 1 is provided at one end of the anti-slip part 3 close to the arc-shaped part, and the arc-shaped part is provided with a groove adapted to the protrusion 1. The groove is engaged with the protrusion 1. The anti-slip part 3 and the arc-shaped part are connected by the groove to ensure a reliable connection and prevent the contact surface from sliding.

[0033] The outer side of the anti-slip member 3 is provided with an anti-slip groove, which further improves the anti-slip effect.

[0034] An opening 7 is provided at the corner of the arc-shaped member, and the opening design at the corner is adapted to the shape of the rope when the safety rope 9 is pulled.

[0035] The rope tightener 8 adopts the existing rope tightener 8, which is used to bundle and fix the two suspension ropes 8. The part of the suspension rope 8 extending out of the arc-shaped member forms the suspension point of the safety rope 9.

[0036] The present invention has multiple uses and can meet the needs of hanging the suspension rope 8 in various situations. It can be tightened and adjusted to adapt to pillars of different sizes. At the same time, it only needs to adjust the arc-shaped part to be suitable for hanging the suspension rope 8 of a cylinder. A single arc-shaped part can also be used as a rope right-angle protector.

[0037] The construction steps of the present invention are as follows: the arc-shaped member is fitted to the bound structure 10 → the suspension rope 8 is wrapped around the bound structure 10 → the rope tightener 8 is tightened to make the arc-shaped member close to the bound structure 10 → the safety rope 9 is hung on the suspension rope 8 → the rope tightener 8 is loosened → the suspension rope 8 and the arc-shaped member are removed.

[0038] This embodiment also includes a control system. Connecting cables 14 are provided between adjacent curved members 11. Each curved member 11 is provided with a pressure sensor 12 for detecting the pressure on the connecting cables 14. The control system is communicatively connected to an alarm. The control system is preset with a pressure threshold. When the pressure value received from the pressure sensor 12 exceeds the pressure threshold, the alarm is activated. A connecting portion is slidably provided on the curved member 11. The connecting cable 14 is connected to the connecting portion. The pressure sensor 12 is used to detect the tension applied to the connecting portion.

[0039] The pressure sensor 12 uses a tensile pressure sensor 12, which is used to detect the pressure value exerted on the sliding part 13. When the arc-shaped part 11 and the bound structure 10 become loose, the connecting rope 14 drives the sliding part 13 to slide outward to generate pressure. At this time, the tensile pressure sensor 12 detects the pressure of the sliding part 13. When the control system receives the pressure value of the pressure sensor 12 that exceeds the pressure threshold, the alarm is activated to alarm. At this time, the staff can perform maintenance or evacuate to improve safety.

[0040] Furthermore, there are multiple groups of pressure thresholds. In this embodiment, there are pressure threshold one, pressure threshold two, and pressure threshold three. When pressure threshold one is reached, it means that the suspension rope 9 is slightly stretched (stretched within 1 mm), indicating that the tightness between the arc part 11 and the bound structure 10 is relatively loose, but still within a controllable range. At this time, the alarm sound can be relatively gentle, and staff can be sent for maintenance, and the staff do not need to evacuate. When pressure threshold two is reached, it means that the suspension rope 9 is stretched to a certain extent (stretched 2-2.5 mm), the tightness between the arc part 11 and the bound structure 10 is loose, the alarm sound is relatively sharp, and staff are sent for maintenance. Some personnel can be evacuated to reduce the suspension pressure; when pressure threshold three is reached, it means that the suspension rope 9 is stretched to a large extent (stretched more than 2.5 mm), the tightness between the arc part 11 and the bound structure 10 is loose, the alarm sound is relatively sharp, and all staff evacuate. Only maintenance personnel can perform maintenance, and maintenance personnel can use other safety suspension devices for maintenance to ensure safety.

[0041] The arc-shaped member 11 has a receiving groove for the pressure sensor 12 , and the sliding portion 13 is slidably fitted in the receiving groove. A limiting portion can be provided to limit the sliding portion 13 from sliding in the receiving groove to prevent the sliding portion 13 from separating from the arc-shaped member 11 .

[0042] The control system uses a CPU and its peripheral circuits, which are existing technologies and will not be described in detail here. The control system has wireless communication, which transmits data to the terminal, and the terminal performs monitoring to improve security.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
