[0002] A transmission tower is an electric power facility used for erecting transmission lines during the power transmission process. During the later maintenance or repair of the transmission tower, it is necessary for operators to climb onto the iron tower for high-altitude operations. To prevent operators from falling from a height and improve the safety of operators during the operation process, an anti-falling device is usually fixedly installed on the transmission tower, which can play an anti-falling effect when the operator is performing high-altitude operations or climbing. At present, the anti-falling device usually includes a guide rail fixed on the transmission tower and an anti-falling arrester slidably arranged on the guide rail. Now most of the guide rails are processed from T-shaped steel. During on-site installation, a plurality of T-shaped steels are sequentially connected and fixed to the transmission tower along their length directions, and at the same time, the ends of two adjacent T-shaped steels are connected and fixed together to complete the installation of the guide rail on the transmission tower. However, when the guide rails are butt-jointed, it is necessary to align the ends of the two T-shaped steels to avoid affecting the sliding of the anti-falling arrester during use. As a result, during on-site installation of the rails, it is necessary to repeatedly adjust the positions of the T-shaped steels, and the operation process is relatively complicated, affecting the on-site construction efficiency.

[0024] Please refer to Figure 1 and Figure 2, the installation structure of the anti-falling guide rail for the iron tower provided by the present utility model will be described hereinafter. The installation structure of the anti-falling guide rail for the iron tower includes a guide rail 1, a positioning projection 2, and a connecting member 3. The number of the guide rails 1 is multiple, and the multiple guide rails 1 are connected end to end. The guide rail 1 includes a first wing plate 11 and a second wing plate 12 which is arranged perpendicular to the first wing plate 11.

[0025] Compared with the prior art, the installation structure of the anti-falling guide rail for the iron tower provided by this embodiment is provided with a guide rail 1 which is processed by a T-shaped steel. The guide rail 1 includes a first wing plate 11 and a second wing plate 12 which are perpendicular to each other. The first wing plate 11 is used for guiding the movement of the anti-falling device. The second wing plate 12 is used for connecting with the adjacent guide rail 1 and the iron tower. In this application, a positioning projection 2 protrudes from one end of the first wing plate 11, and a sliding groove which is slidably matched with the positioning projection 2 is arranged at the other end of the first wing plate 11. When two guide rails 1 are butted, the positioning projection 2 on one of the guide rails 1 can be slid into the other sliding groove, so as to prevent the two connected guide rails 1 from displacing in the width direction of the first wing plate 11. At the same time, the two ends of the second wing plate 12 are inclined surfaces which are arranged at intervals in parallel. After the two second wing plates 12 are connected together, the two connected guide rails 1 can be limited from displacing in the width direction of the second wing plate 12. On the one hand, it is convenient to butt and install two adjacent guide rails 1, reduce the adjustment of the position of the guide rail 1 during the butting process, and at the same time, the stability of the position when the two guide rails 1 are connected can be improved. It is convenient for on-site construction and installation, and the construction efficiency of installing the guide rail 1 on the iron tower can be improved.

[0026] Specifically, in this embodiment, one end of the connecting member 3 is fixedly installed on the second wing plate 12 through a bolt, and the other end of the connecting member 3 is bent to be provided with a fixing portion for fixing to the iron tower, and a fixing hole for fixing to the iron tower is arranged on the fixing portion.

[0027] In some embodiments, the above-mentioned second wing plate 12 can adopt a structure as shown in Figure 1 , Figure 2 Shown structure. See also Figure 1 , Figure 2, one end of the second wing plate 12 close to the positioning protrusion 2 is inclined in a direction away from the other end in a direction away from the first wing plate 11. When the guide rail 1 is installed on site, the end with the positioning protrusion 2 is located at the top of the guide rail 1. The top end of the second wing plate 12 is inclined downward in a direction close to the first wing plate 11. When the second wing plates 12 on the two guide rails 1 are butted, the second wing plate 12 on the upper guide rail 1 can be made to abut against the positioning protrusion 2 on the first wing plate 11 of the lower guide rail 1 through the guiding at both ends of the second wing plate 12. It is convenient to adjust the relative position of the two butted guide rails 1 in the width direction of the second wing plate 12.

[0028] In some embodiments, the above-mentioned second wing plate 12 may adopt a structure such as Figure 1 , Figure 2 as shown. Referring together to Figure 1 , Figure 2 , a guiding protrusion 4 is provided at one end of the second wing plate 12 close to the positioning protrusion 2, and a guiding groove that is in guiding cooperation with the guiding protrusion 4 is provided at the other end of the second wing plate 12. A guiding protrusion 4 also protrudes at the end of the guide rail 1 where the positioning protrusion 2 is provided. The guiding protrusion 4 is located at the end of the second wing plate 12, and a guiding groove that is in sliding cooperation with the guiding protrusion 4 is recessed at the other end of the second wing plate 12. When the two guide rails 1 are connected end to end, the guiding protrusion 4 at the end of the second wing plate 12 slides into the interior of the guiding groove, and the positioning protrusion 2 on the first wing plate 11 slides into the interior of the sliding groove. Through the arrangement of the positioning protrusion 2 and the guiding protrusion 4, double positioning of the guide rail 1 in the width direction of the first wing plate 11 and the width direction of the second wing plate 12 can be achieved simultaneously, thereby ensuring the stability of the relative position when the two guide rails 1 are butted.

[0029] In some embodiments, the above-mentioned guide rail 1 may adopt a structure such as Figure 1 , Figure 2 as shown. Referring together to Figure 1 , Figure 2 , the guiding protrusion 4 is fixedly connected to the positioning protrusion 2 and is located at the side of the second wing plate 12 close to the positioning protrusion 2. The guiding protrusion 4 is located at the side of the second wing plate 12 close to the first wing plate 11, and the guiding protrusion 4 is fixedly connected to the positioning protrusion 2 together. The sliding grooves at the ends of the first wing plate 11 are communicated with the sliding grooves on the second wing plate 12. When the two guide rails 1 are butted, through the guiding of the inclined surfaces at both ends of the second wing plate 12, the guiding protrusion 4 can pass through the sliding groove on the first wing plate 11 and abut against the side wall of the guiding groove. Positioning of the two guide rails 1 in the width direction of the second wing plate 12 is achieved. At the same time, during on-site splicing, the docking of the two guide rails 1 can be completed by the gravity of the upper guide rail 1 combined with the guiding of the inclined surfaces at both ends of the second wing plate 12. The operation is convenient, and it is convenient to align the relative positions of the two guide rails 1 to be butted during on-site installation.

[0030] Specifically, in this embodiment, the positioning protrusion 2 and the guiding protrusion 4 are fixedly connected together, which can improve the strength of the guiding protrusion 4 and the positioning protrusion 2 themselves and prevent the positioning protrusion 2 and the guiding protrusion 4 from deforming.

[0031] In some embodiments, the above-mentioned fixing assembly 5 may adopt the structure as Figure 1 shown. Refer to Figure 1 , a fixing assembly 5 for connecting two adjacent guide rails 1 together is further provided between two adjacent guide rails 1. The fixing assembly 5 includes a fixing plate 51, a tightening member 52, and a fastening member 53. The number of the fixing plates 51 is two, and the two fixing plates 51 are respectively installed on both sides of the second wing plate 12. The fixing plate 51 is provided with fixing holes for connecting to the second wing plates 12 on two adjacent guide rails 1. The tightening member 52 penetrates through the fixing holes and the second wing plate 12, and a limiting portion for abutting against the fixing plate 51 is provided at one end of the tightening member 52. The fastening member 53 is threadedly connected to the tightening member 52 and is used for clamping the second wing plate 12 between the two fixing plates 51. The fixing plate 51 is processed from a steel plate, and a plurality of fixing holes are arranged along the length direction of the fixing plate 51 for the tightening member 52, and through holes corresponding to the fixing holes are provided at both ends of the second wing plate 12. The tightening member 52 is a bolt, and the fastening member 53 is a nut. When two guide rails 1 are butted, the two fixing plates 51 can be installed between the second wing plates 12 on two adjacent guide rails 1, and the two fixing plates 51 are placed on both sides of the second wing plate 12. The tightening member 52 passes through between the fixing plate 51 and the second wing plate 12, and the second wing plate 12 is clamped between the two fixing plates 51 by using the fastening member 53 to realize the fixation between the two second wing plates 12. The structure is simple and the operation is convenient.

[0032] Specifically, in this embodiment, the plurality of fixing holes are arranged at intervals along the length direction of the fixing plate 51.

[0033] In some embodiments, the above-mentioned fixing plate 51 may adopt the structure as Figure 1 shown. Refer to Figure 1 , the fixing holes on the fixing plate 51 include a plurality of first through holes connected to the same second wing plate 12 and a plurality of second through holes connected to the adjacent second wing plate 12. A plurality of first through holes and second through holes are provided on the fixing plate 51. The number of the first through holes and the second through holes is at least two. The arrangement of the plurality of first through holes and second through holes can prevent the fixing plate 51 from rotating relative to the second wing plate 12 along the axis of the tightening member 52, thereby effectively improving the connection stability between the fixing plate 51 and the second wing plate 12.

[0034] Specifically, in this embodiment, the number of both the first through holes and the second through holes is two.

[0035] In some embodiments, the above-mentioned fixing plate 51 may adopt the structure asFigure 1 The structure shown. Refer to Figure 1 , the second via hole is an oblong through hole, and the length direction of the second via hole is arranged at an angle with the length direction of the fixing plate 51. When the fixing plate 51 is installed between the second wing plates 12 of the two guide rails 1, the second via hole is located below the first via hole. A guiding portion that slidably cooperates with the inner wall of the oblong through hole is provided in the middle of the tightening member 52. When the fixing plate 51 is installed on the second wing plate 12, the length direction of the oblong through hole is inclined upward or downward along the direction close to the first wing plate 11. When docking the second wing plates 12 on the two guide rails 1 on site, the fixing plate 51 can be first connected to the second wing plate 12 of the upper guide rail 1 through the tightening member 52 and the first via hole, and then the tightening member 52 is passed through the second via hole and connected to the second wing plate 12 of the lower guide rail 1. By knocking and rotating the fixing plate 51 with the axis of the first via hole as the center, the tightening member 52 on the second wing plate 12 of the lower guide rail 1 is driven to move upward by guiding with the inner wall of the oblong through hole, so as to drive the second wing plate 12 on the lower guide rail 1 to move up and down, so that the ends of the second wing plates 12 on the upper and lower guide rails 1 can be fitted together, and combined with the guiding provided by the inclined arrangement of both ends of the second wing plate 12, the stability of the connection between the two second wing plates 12 can be effectively improved, and further the stability of the relative position of the two docking guide rails 1 can be improved.

[0036] Specifically, in this embodiment, when the length direction of the fixing plate 51 is parallel to the length directions of the first wing plate 11 and the second wing plate 12, the tightening member 52 located inside the second via hole abuts against the end of the second via hole, and when the tightening member 52 abuts against the end of the second via hole, the ends of the second wing plates 12 on the two docking guide rails 1 are fitted together with each other.

[0037] In some embodiments, the above-mentioned fixing plate 51 can adopt the structure as shown in Figure 1 The structure shown. Refer to Figure 1 , when the fixing plate 51 is installed on the second wing plate 12, the length of the second via hole is inclined from the direction away from the first via hole to the direction close to the first wing plate 11. When the fixing plate 51 is installed on the second wing plate 12, the second via hole is located below the first via hole, and the length direction of the second via hole is inclined from top to bottom to the direction close to the first wing plate 11, so that when knocking the fixing plate 51 from the outside and rotating it in the direction close to the first wing plate 11, the second wing plates 12 on the two docking guide rails 1 can be moved in the direction of relative approach, which is convenient for on-site operation. At the same time, it is convenient for the fixing plate 51 to be connected between the two second wing plates 12 of the two guide rails 1. The operation is convenient and it is convenient for on-site docking and installation.
