[0016] In order to make the purpose, technical solution and advantages of the utility model clearer and more understandable, the technical solution of the utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, a flexible support prestressed cable tensioning protection device provided by the utility model includes a frame assembly and a positioning support assembly. The frame assembly includes a steel wire protection net 12 and a plurality of protection frames. The plurality of protection frames are arranged in a row and are rotatably connected to adjacent protection frames. The steel wire protection net 12 is installed on the outside of the protection frame. A transparent soft curtain 10 is also installed on the outside of the protection frame. The transparent soft curtain 10 is located between the protection frame and the steel wire protection net 12. The positioning support assembly is used to fix the support frame assembly.

[0018] The frame assembly in the utility model is composed of a plurality of protective frames hinged to each other, arranged in a row, and rotatable and adjustable relative to each other to form a bow-shaped semi-cage. During operation, the frames can be placed in front of the operator to effectively prevent the operator from getting out of control or other accidents during the prestressed tensioning construction process. At the same time, a steel wire protective net 12 and a transparent soft curtain 10 are arranged on the outside of the protective frame. On the one hand, they do not affect the observation of the prestressed tensioning area. On the other hand, they can prevent the possible damage to people caused by flying objects of all sizes, thereby further improving the safety of the construction operation process.

[0019] The protective frame includes a top horizontal rod 1, a bottom horizontal rod 3 and a plurality of vertical rods 2. The plurality of vertical rods 2 are fixedly connected between the top horizontal rod 1 and the bottom horizontal rod 3. The top horizontal rods 1 in adjacent protective frames are hinged to each other, and the bottom horizontal rods 3 are hinged to each other.

[0020] Since adjacent protective frames are rotatably connected, the frame assembly as a whole can be rotated and folded, which is more convenient for transportation and installation.

[0021] The positioning support assembly includes a positioning unit and a support unit. The support unit includes a horizontal reinforcement rod 11, a horizontal strut 9, a spatial diagonal strut 8, a horizontal partition rod 6 and a horizontal diagonal strut 4. The horizontal reinforcement rod 11 is fixedly connected to the vertical rod 2 in the middle protection frame. One end of the horizontal strut 9 is hinged to the horizontal partition rod 6 and the other end is hinged to the bottom horizontal rod 3 in the middle protection frame. One end of the spatial diagonal strut 8 is hinged to the horizontal partition rod 6 and the other end is hinged to the horizontal reinforcement rod 11. One end of the horizontal diagonal strut 4 is hinged to the horizontal partition rod 6 and the other end is hinged to the bottom horizontal rod 3 in the protection frames on both sides. The positioning unit is installed on the horizontal partition rod 6.

[0022] The horizontal reinforcing rod 11 can facilitate the connection of the spatial diagonal brace rod 8 on the one hand, and can enhance the stability of the structure on the other hand; the horizontal brace rod 9 is used to support the protective frame in the middle, and the corresponding horizontal diagonal brace rod 4 is used to support the protective frames on both sides. The more protective frames there are in the frame assembly, the more horizontal diagonal brace rods 4 need to be increased to ensure the stability of the support.

[0023] It should be noted that the spatial diagonal braces 8, horizontal braces 9, horizontal diagonal braces 4 and horizontal partition bars 6 are all detachable from each other, and the horizontal braces 9, horizontal diagonal braces 4 and spatial diagonal braces 8 are also detachable from the protective frame, so that they can be easily disassembled and transported.

[0024] The positioning unit includes a ground plug connection plate 7 and a ground plug 5 . The ground plug connection plate 7 is fixedly mounted on the horizontal partition rod 6 , and the ground plug 5 is mounted on the ground plug connection plate 7 .

[0025] The ground plug 5 can be inserted into the ground for positioning, which facilitates the subsequent installation and support of the frame assembly.

[0026] To sum up, the overall installation process of the utility model is: first, connect and assemble the transported spatial diagonal support rods 8, horizontal support rods 9, horizontal diagonal support rods 4, horizontal partition rods 6, ground plug connecting plates 7 and ground plugs 5, insert the ground plugs 5 into the ground at appropriate positions, and then unfold the frame assembly into a bow shape so that the wire protection net 12 is on the outside of the frame assembly, and then connect each rod to the corresponding position on the protection frame, and then when working, the operator can stand on the inside of the frame assembly.
