Description

Technical Field

[0001] This utility model belongs to the field of anti-fall track installation technology, and in particular relates to an anti-fall track fixing hardware for reinforcing iron towers. Background Technology

[0002] A reinforced iron tower typically consists of four columns, the structure of which is as follows: Figure 1 , Figure 2 As shown, it mainly includes two angle steels, which are set at right angles to each other. The two angle steels are connected and fixed by screws using cross-shaped connecting plates. The connecting plates are arranged at intervals along the height direction of the column.

[0003] Fall arrestor rails are rigid rail structures, typically with a T-shaped cross-section, laid parallel to the outside of the tower's columns. Fall arrestor rails are installed on the rails. When climbing the tower, operators connect the safety rope around their waist to the fall arrestor. In the event of a fall, the fall arrestor automatically locks the operator onto the rails, ensuring their safety.

[0004] When a single angle steel bar is used as a column, its right-angled side faces outwards. When installing fall arrestor rails on such columns, the rails can be directly welded to the outside of the right angle of the angle steel. Because the right-angled portion of the angle steel has high strength, this better ensures the installation strength of the fall arrestor rails. However, for columns of reinforced steel towers, the right-angled sides of the two angle steel bars are located in the middle of the column, making it inconvenient to connect fall arrestor rails. Therefore, how to solve the problem of connecting fall arrestor rails for reinforced steel towers is the main objective of this application. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fixing hardware for the anti-fall rail of reinforced iron towers, which facilitates the installation of anti-fall rails on reinforced iron towers and has high connection strength and ease of installation.

[0006] In order to achieve the purpose of this utility model, the following solution is proposed:

[0007] A type of anti-fall rail fixing hardware for reinforcing iron towers. The tower's support column includes two parallel angle steels, positioned at right angles to each other. The two angle steels are connected by a cross-shaped connecting plate, which fits against the outer wall of the angle steel. The fixing hardware includes a screw rod and two clamping plates.

[0008] The clamping plate includes mutually perpendicular end plates and an outer clamping plate. The end plates have through holes for threading screws.

[0009] During assembly, the screw rod passes through the two angle steels along the length of one of the connecting plates. The two ends of the screw rod protrude from the outer sides of the two angle steels respectively. The screw rod fits against the outer wall of the side plate of the angle steel. The clamping plate is connected to the screw rod through the through hole. The end of the screw rod is equipped with a locking nut to press the end plate against the edge of the side plate of the angle steel. The outer clamping plate is located inside the included angle of the corresponding angle steel and fits against the inner wall of the corresponding side plate of the angle steel. The anti-fall rail is connected to one end of the screw rod.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This solution utilizes a clamping plate and a screw rod, and locks them with a locking nut to fix the screw to the column of the reinforced iron tower. The screw rod is used to install the fall arrestor rail, which effectively ensures the stability of the fall arrestor rail installation structure.

[0012] 2. This solution eliminates the need for welding. Instead, it utilizes screws and locking nuts to achieve a detachable installation method, making the installation of the fall arrestor rails more convenient. Attached Figure Description

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1 to 3 As shown, the support column of the reinforced tower includes two parallel angle steels 1, which are arranged at right angles to each other. The two angle steels 1 are connected by a cross-shaped connecting plate 2. The connecting plate 2 is attached to the outer wall of the angle steel 1, so there is a gap between the angle steels 1 that is the same as the thickness of the connecting plate 2.

[0024] like Figures 1 to 4 As shown, a type of anti-fall track fixing hardware for reinforcing iron towers includes: a screw 3 and two clamping plates 4.

[0025] The clamping plate 4 includes mutually perpendicular end plates 41 and outer clamping plates 42. The end plates 41 have through holes for threading screws 3 through.

[0026] During assembly, the screw 3 passes through the two angle steels 1 along the length of one of the connecting plates 2. Both ends of the screw 3 protrude from the outer sides of the two angle steels 1, and the screw 3 fits against the outer wall of the side plate of the angle steel 1. The clamping plate 4 is connected to the screw 3 through a through hole. A locking nut 5 is provided at the end of the screw 3 to press the end plate 41 against the edge of the side plate of the angle steel 1. The outer clamping plate 42 is located inside the included angle of the corresponding angle steel 1 and fits against the inner wall of the side plate of the corresponding angle steel 1. Because the included angles of the two angle steels 1 face different directions, the clamping plate 4 needs to be adjusted according to its relative position to the angle steel 1. Figure 3As shown, the clamping plates 4 at both ends of the screw 3 face opposite directions. The anti-fall rail is connected to one end of the screw 3. Specifically, a through hole is provided on the vertical section of the T-shaped section of the anti-fall rail. The through hole is used to connect with the end of the screw 3. The vertical section of the T-shaped section of the anti-fall rail fits against the outer surface of the end plate 41, and the anti-fall rail is fixed to the screw 3 by using the locking nut 5.

[0027] The above scheme utilizes the gap between two angle steels 1 to insert a screw rod 3, and uses the clamping plates 4 at both ends of the screw rod 3 to lock it onto the angle steel 1, thereby fixing the screw rod 3 and the clamping plates 4. Then, the fall arrestor rail is installed on the screw rod 3, thus achieving the purpose of fixing the fall arrestor rail. When the clamping plates 4 and the screw rod 3 are connected to the angle steel 1, the outer clamping plate 42 and the screw rod 3 are respectively clamped on both sides of the same side plate of the angle steel 1 to ensure that the screw rod 3 is in close contact with the outer wall of the side plate of the angle steel 1. Then, the end plate 41 is pressed against the edge of the side plate of the angle steel 1 by the locking nut 5 to prevent the screw rod 3 from moving along the length direction. Through the above two directions of limiting, the stability of the screw rod 3 on the reinforced iron tower column is effectively guaranteed, thereby ensuring the strength of the fall arrestor rail installation structure. The fixing hardware is set at multiple intervals along the height of the column, which can effectively ensure the stability of each section of the fall arrestor rail.

[0028] Preferably, the side of the outer clamping plate 42 facing the end plate 41 is an inclined surface, and the angle between the inclined surface and the end plate 41 is greater than 90 degrees. During assembly, the minimum distance between the root of the inclined surface and the screw 3 is less than the thickness of the side plate of the angle steel 1. By setting the inclined surface, it is not only convenient to insert the side plate of the angle steel 1 into the screw 3 and the outer clamping plate 42, but also to guide the screw 3 to fit with the side plate of the angle steel 1, thereby improving the tightness of the connection between the screw 3 and the angle steel 1.

[0029] Preferred, such as Figure 3 , Figure 4 As shown, an inner clamping plate 43 is vertically provided in the middle section of the end plate 41. Its extension direction is consistent with the extension direction of the outer clamping plate 42, and the distance between the inner clamping plate 43 and the outer clamping plate 42 is consistent with the thickness of the side plate of the angle steel 1. This structural design can use the inner clamping plate 43 and the outer clamping plate 42 to restrict the position between the clamping plate 4 and the angle steel 1 during assembly, and can effectively ensure the perpendicularity between the end plate 41 and the side plate of the angle steel 1.

[0030] Preferred, such as Figure 4 As shown, the end plate 41 is provided with inner clamping plates 43 on both sides corresponding to the outer clamping plate 42, which can further improve the structural strength of the clamping plate 4 and ensure the connection stability between it and the angle steel 1.

[0031] Preferably, the end plate 41, the outer clamping plate 42, and the inner clamping plate 43 are integrally stamped.

[0032] Preferred, such as Figure 3 , Figure 4As shown, the fall arrestor rail is connected to the screw rod 3 via angle iron 6. The angle iron 6 has two mutually perpendicular side plates. The screw rod 3 passes through one of the side plates, and the side plate connected to the screw rod 3 is pressed between the end plate 41 and the locking nut 5. The other side plate is parallel to the screw rod 3. The vertical section of the T-shaped section of the fall arrestor rail is connected to the side plate parallel to the screw rod 3 by screws. This structure makes the horizontal section of the T-shaped structure of the fall arrestor rail face the outside of the column, which is convenient for installing the fall arrestor.

[0033] Preferably, the extension direction of the screw 3 passes through the center line of the tower, and the angle iron 6 is located on the outside of the tower, so that the fall arrest track protrudes from the outside of the tower column, thereby reducing the obstruction of the safety rope by the tower and allowing the operator and the safety rope to move smoothly along the fall arrest track.

[0034] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
