[0020] This embodiment provides a steel wire rope anchoring device for an angle steel tower. Figure 1A schematic structural diagram of a steel wire rope anchoring device for an angle steel tower provided in this embodiment.

[0021] like Figure 1 As shown, the wire rope anchoring device for the angle steel tower of this embodiment includes a fixing bracket 1 and a connecting plate 2. The fixing bracket 1 includes a main body 11, a diagonal support portion 12 and a connecting portion 13. The wire rope 3 is fixed to the main body 11. The bottom end of the diagonal support portion 12 is connected to the main body 11. The top end of the diagonal support portion 12 is inclined in a direction away from the main body 11 to form an opening 14 between the main body 11 and the top end of the diagonal support portion 12. The connecting portion 13 is arranged at the top end of the diagonal support portion 12. The connecting plate 2 includes a first end 21 and a second end 22. The first end 21 is hinged to the main body 11. The second end 22 can rotate around the first end 21 between a first position and a second position. When the second end 22 is in the first position, the connecting plate 2 closes the opening 14, and the second end 22 can be fixed to the connecting portion 13 through the connecting member 4. When the second end 22 is in the second position, the opening 14 is in an open state.

[0022] In some examples, such as Figure 1 As shown, when the second end 22 of the connecting plate 2 is in the first position, the main body 11, the diagonal support part 12 and the connecting plate 2 form a closed structure, and the angle steel beam 9 is fixed in the closed structure formed by the main body 11, the diagonal support part 12 and the connecting plate 2. The angle steel beam 9 includes a first right angle side and a second right angle side, the first right angle side of the angle steel beam 9 is in contact with the outer wall of the main body 11, and the second right angle side faces the connecting plate 2 and is parallel to the connecting plate 2. When the anchor device of this embodiment is fixed on the angle steel beam 9 of the angle steel tower, since the first right angle side of the angle steel beam 9 is in contact with the outer wall of the main body 11, and the second right angle side faces the connecting plate 2 and is parallel to the connecting plate 2, the connection between the anchor device and the angle steel tower can be made more firm and reliable, and the stability is higher.

[0023] The steel wire rope anchoring device for the angle steel tower of this embodiment includes a fixing bracket 1 and a connecting plate 2. The fixing bracket 1 includes a main body 11, an inclined support part 12 and a connecting part 13. The steel wire rope 3 is fixed on the main body 11. The main body 11 and the inclined support part 12 form an angle, and an opening 14 is formed between the top of the main body 11 and the inclined support part 12. When the steel wire rope anchoring device for the angle steel tower of the present invention is used, the angle formed by the main body 11 and the inclined support part 12 is sleeved on the angle steel beam 9 of the angle steel tower through the opening 14, and then the second end 22 of the connecting plate 2 is rotated to the first position, and the second end 22 of the connecting plate 2 is fixed to the connecting part 13 through the connecting member 4, so that the main body 11, the inclined support part 12 and the connecting plate 2 form a closed structure, and the angle steel beam 9 is enclosed in the closed structure, so that the steel wire rope 3 is safely and firmly anchored on the tower body of the angle steel tower. The steel wire rope anchoring device for the angle steel tower of the present invention has a small size, a simple structure, is easy to carry, is convenient and quick to use, is firm and reliable, and is easy to disassemble, which is beneficial to improving maintenance efficiency and operation safety.

[0024] Figure 2 A top view of a fixing bracket 1 provided in this embodiment. In some embodiments, as Figure 1 and Figure 2 As shown, the main body 11 is provided with a fixing hole 111. The steel wire rope 3 is passed through the fixing hole 111. A buckle 31 is provided at one end of the steel wire rope 3.

[0025] For some examples, see Figure 1 and Figure 2 The steel wire rope 3 is arranged in the fixing hole 111 and connected to the fixing hole 111 by welding. Such arrangement can ensure that the connection between the steel wire rope 3 and the main body 11 is firm and reliable.

[0026] For other examples, see Figure 1 and Figure 2 The steel wire rope 3 is arranged in the fixing hole 111 and connected with the fixing hole 111 by a locking block or a locking bolt. With such arrangement, the extension length of the steel wire rope 3 can be adjusted, and the steel wire rope 3 can be disassembled, which is convenient and flexible to use.

[0027] The main body 11 of this embodiment is provided with a fixing hole 111 for connecting the steel wire rope 3. The steel wire rope 3 is fixed on the main body 11. When in use, the force of the entire anchoring device can be more uniform, which is conducive to improving stability. A buckle 31 is provided at one end of the steel wire rope 3 to facilitate connecting the safety rope of the maintenance personnel. In addition, the buckle 31 can also be used as a limiting structure. When the other end of the steel wire rope 3 is stressed, the buckle 31 can prevent the steel wire rope 3 from slipping out of the fixing hole 111 under the limiting effect of the buckle 31.

[0028] In some embodiments, Figure 1 As shown, the fixing bracket 1 includes two oblique support parts 12. The two oblique support parts 12 are symmetrically arranged on the left and right sides of the main body 11. There are two connecting plates 2, and each connecting plate 2 corresponds to one oblique support part 12.

[0029] In some examples, such as Figure 1 As shown, the two inclined support parts 12 have the same size specifications. This arrangement makes the anchor device symmetrical, which is conducive to force balance. It should be noted that in other embodiments, the two inclined support parts 12 have different size specifications to be suitable for angle steel beams 9 of different specifications, which is conducive to expanding the application range of the anchor device.

[0030] The fixing bracket 1 of this embodiment includes two inclined support parts 12, which are symmetrically arranged on the left and right sides of the main body 11, and can be applied to angle steel beams 9 with different orientations. When in use, according to the inspection position and the orientation of the angle steel beam 9, a suitable side of the inclined support part 12 can be selected and anchored on the angle steel beam 9.

[0031] In some embodiments, Figure 1 As shown, the inclined support portion 12 includes an inclined section 121 and a horizontal section 122 connected to each other. The bottom end of the inclined section 121 is connected to the main body 11, and the top end of the inclined section 121 extends in a direction away from the main body 11, so that the main body 11 and the inclined section 121 form an angle. The horizontal section 122 is connected to the top end of the inclined section 121 and extends in a direction close to the main body 11. The connecting portion 13 is connected to the horizontal section 122.

[0032] In some examples, such as Figure 1 As shown, the inclined section 121 and the horizontal section 122 are an integrally formed structure. Such a configuration can make the inclined support portion 12 have better firmness and higher structural stability. However, it can be understood that in other embodiments, the inclined section 121 and the horizontal section 122 can also be designed as a split structure and assembled into one by welding or bolting. This embodiment does not impose too many restrictions on this, as long as it can meet the strength requirements.

[0033] The diagonal support portion 12 of the present embodiment includes an inclined section 121 and a horizontal section 122 that are connected to each other. The inclined section 121 and the horizontal section 122 form an angle, and the open side of the angle faces the main body 11, which can play a certain limiting role on the angle steel beam 9, so that the anchoring device of the present embodiment can be more stably anchored on the angle steel beam 9.

[0034] Figure 3 Schematic diagram of the structure of a connecting plate 2 provided in this embodiment. In some embodiments, Figure 1 and Figure 3As shown, the connecting plate 2 comprises at least two sections of plates 24 . Two adjacent sections of plates 24 are hingedly connected via a hinge shaft 23 .

[0035] In some examples, such as Figure 1 and Figure 3 As shown, the connecting plate 2 includes three sections of plates 24, and two adjacent sections of plates 24 are hinged by a hinge shaft 23. When in use, if the size of the angle steel beam 9 is small, the angle steel beam 9 is directly inserted into the angle formed by the main body 11 and the diagonal support part 12, and the connecting plate 2 is used to close the opening 14 between the main body 11 and the top of the diagonal support part 12 to play an anchoring role. When the size of the angle steel beam 9 is large and cannot be placed in the angle formed by the main body 11 and the diagonal support part 12, a suitable hinge shaft 23 can be selected as the bending point of the connecting plate 2 according to the size of the angle steel beam 9, so as to enclose the angle steel beam 9 in the closed structure formed by the main body 11, the diagonal support part 12 and the connecting plate 2 to achieve fixation. It is convenient and flexible to use and has a wide range of applications.

[0036] In some examples, such as Figure 1 and Figure 3 As shown, the lengths of the plurality of plates 24 may be at least partially equal or completely equal, and may be specifically set according to size requirements, and this embodiment does not impose too many restrictions on this.

[0037] The connecting plate 2 of the present embodiment comprises at least two sections of plates 24, and two adjacent sections of plates 24 are hinged via a hinge shaft 23. When in use, a suitable hinge shaft 23 can be selected as the bending point of the connecting plate 2 according to the size of the angle steel beam 9, so that the connecting plate 2 and the angle steel beam 9 have a higher fit, which is more conducive to improving the stability of the connection between the anchor device of the present embodiment and the angle steel beam 9.

[0038] In some embodiments, Figure 1 As shown, the connecting member 4 includes at least one of a self-tapping screw 41 and a fixing bolt 42 .

[0039] In some examples, such as Figure 1 As shown, the connecting member 4 includes both a self-tapping screw 41 and a fixing bolt 42. The dual fixing effects of the self-tapping screw 41 and the fixing bolt 42 can make the connection between the connecting plate 2 and the connecting portion 13 more firm and reliable.

[0040] In some examples, such as Figure 1As shown, the length of the self-tapping screw 41 and the fixing bolt 42 is selected according to the use requirements. When the size of the angle steel beam 9 is large and the connecting plate 2 cannot fit with the connecting portion 13, a self-tapping screw 41 and a fixing bolt 42 with a larger length are selected to ensure the effective connection between the connecting plate 2 and the connecting portion 13. When the size of the angle steel beam 9 is small and can be placed in the angle formed by the main body 11 and the inclined support portion 12, the connecting plate 2 and the connecting portion 13 can fit together, so a self-tapping screw 41 and a fixing bolt 42 with a smaller length can be selected for easy operation.

[0041] The connecting member 4 of this embodiment adopts at least one of a self-tapping screw 41 and a fixing bolt 42, which has a simple structure, is easy to disassemble, safe and reliable, and has low cost and convenient material acquisition, which is conducive to reducing the use cost.

[0042] In some embodiments, Figure 2 and Figure 3 As shown, the wire rope anchoring device for the angle steel tower also includes: a first notch 5 and a second notch 6. The first notch 5 is arranged on the connecting plate 2. The first notch 5 is close to the second end 22 of the connecting plate 2. The second notch 6 is arranged on the connecting portion 13. When the second end 22 of the connecting plate 2 is located at the first position, the first notch 5 and the second notch 6 at least partially overlap. The connecting member 4 passes through the first notch 5 and the second notch 6 in sequence to fix the connecting plate 2 on the connecting portion 13.

[0043] In some examples, such as Figure 2 and Figure 3 As shown, the first notch 5 and the second notch 6 are both in the shape of long strips. The length direction of the first notch 5 is parallel to the length direction of the connecting plate 2. The length direction of the second notch 6 is parallel to the length direction of the connecting portion 13. Such a configuration is conducive to expanding the overlapping range of the first notch 5 and the second notch 6, and is convenient for the installation and fixation of the connecting member 4.

[0044] This embodiment utilizes the first slot 5 and the second slot 6 in conjunction with the connecting piece 4 to achieve the connection between the connecting plate 2 and the connecting portion 13. When the second end 22 of the connecting plate 2 is located at the first position, the first slot 5 and the second slot 6 can at least partially overlap, so as to be applicable to angle steel beams 9 of various specifications, thereby helping to expand the scope of use.

[0045] In some embodiments, Figure 2 As shown, the connecting portion 13 further includes a bolt hole 7. When the second end 22 of the connecting plate 2 is located at the first position, the bolt hole 7 overlaps with the first notch 5.

[0046] For some examples, see Figure 1The number of bolt holes 7 can be one, or two or more. When the number of bolt holes 7 is two or more, the two or more bolt holes 7 need to be arranged in sequence along the length direction of the connecting portion 13. This arrangement can be applicable to angle steel beams 9 of various sizes.

[0047] In this embodiment, bolt holes 7 are provided on the connection part 13 to cooperate with the self-tapping screws 41 on the connection plate 2 to achieve positioning and connection between the connection plate 2 and the connection part 13, which is convenient for installation and disassembly and easy to use.

[0048] In some embodiments, Figure 1 and Figure 2 As shown, the main body 11 is provided with a rotating shaft 8. The first end 21 of the connecting plate 2 is rotatably connected to the rotating shaft 8.

[0049] For some examples, see Figure 1 and Figure 2 The rotating shaft 8 is rotatably mounted on the main body 11 through a bearing. Such an arrangement can make the rotation of the rotating shaft 8 more stable and smooth.

[0050] The connecting plate 2 of this embodiment is hinged to the main body 11 via the rotating shaft 8, and the structure is more solid. The axis of the rotating shaft 8 is perpendicular to the length direction of the connecting plate 2, and can limit the rotation range of the connecting plate 2.

[0051] In some embodiments, Figure 1 As shown, the main body 11, the diagonal support portion 12 and the connecting portion 13 are an integrally formed structure.

[0052] The main body 11, the inclined support part 12 and the connecting part 13 of this embodiment are an integrally formed structure, so the structure of the fixing bracket 1 is more stable and has a stronger load-bearing capacity. However, it should be noted that in other embodiments, the main body 11, the inclined support part 12 and the connecting part 13 can also be designed as a split structure and assembled to form the fixing bracket 1 by welding or bolting. This embodiment does not impose too many restrictions on this, as long as the strength requirements can be met.

[0053] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
