Description

Technical Field

[0001] This utility model belongs to the technical field of guide rail fixing devices, specifically relating to a guide rail fixing device for preventing falls. Background Technology

[0002] Angle steel towers, a common type of power and communication tower structure, are widely used in power transmission lines, communication base stations, and broadcasting. Due to their typically high height, workers performing inspections and maintenance on these towers face a significant risk of falling. To ensure worker safety, angle steel towers are equipped with a guide rail fall arrestor system, consisting of fall arrestors, guide rails, and fixing devices. After the first guide rail is installed, subsequent rails are connected and positioned using guide rail fixing devices to ensure stability between them.

[0003] In existing technologies (such as) Figure 4 As shown, the guide rail fixer includes a fixer and bolts. When using it, the fixer needs to be inserted into the guide rail first and fixed with bolts. Then, another guide rail is inserted into the fixer. The guide rail position is then positioned and bolts are inserted to achieve fixation. However, due to the heavy weight of the guide rail and the fact that the fall protection device is installed on the angle steel tower, it is inconvenient to use. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3As shown, a fall arrestor guide rail fixer includes a fixer 2 and a fixing bolt 1. A positioning component 4 is provided on the side of the fixer 2. The positioning component 4 includes a housing 47 detachably connected to the fixer 2, a pressing post 40 pressed and locked onto the housing 47, and a plug-in post 44 elastically inserted into the pressing post 40. The pressing post 40 is elastically connected to the housing 47. The plug-in post 44 cannot be detached from the pressing post 40. The plug-in post 44 can be inserted into the guide rail 5.

[0021] In use, the operator connects the fixture 2 to the upper guide rail 5 using the fixing bolt 1. After the connection is completed, the positioning component 4 is connected to the fixture 2. Then, the guide rail 5 is inserted into the fixture 2. When the upper end of the guide rail 5 exceeds the upper part of the positioning component 4, the pressing post 40 is pressed and locked onto the outer shell 47. At this time, the insertion post 44 elastically abuts against the guide rail 5. Then, the operator continues to move the guide rail 5 upward until the insertion post 44 is inserted into the hole.

[0022] It should be noted that during the above-mentioned operation, the positioning component 4 is installed at the uppermost positioning hole of the guide rail 5. Figure 3 The holes on the left and right sides of the middle guide rail 5 are aligned to avoid a large gap between the upper and lower guide rails 5.

[0023] It should be noted that the positioning component 4 can also be installed in other positions, but it is important to note that when the guide rail 5 moves up, the next positioning hole should be the hole where the plug post 44 needs to be inserted, and then the pressing post 40 should be pressed to avoid the plug post 44 being inserted into the wrong hole.

[0024] Once the positioning is complete, the guide rail 5 can be fixed to the fixture 2 using the fixing bolt 1. After fixing, the positioning component 4 can be removed.

[0025] In this embodiment, the outer shell 47 is fixed with a threaded cylinder 46, which is threadedly connected to the fixture 2. The fixture 2 has a fixing hole 21 through which the fixing bolt 1 passes and a threaded hole 3 for the threaded cylinder 46 to be threadedly connected. The fixing hole 21 and the threaded hole 3 can be the same hole, that is, one of the fixing holes 21 on the fixture 2 can be replaced with the threaded hole 3.

[0026] In this embodiment, a pressing plate 41 is fixed to one end of the pressing column 40 away from the guide rail 5, and a top cover 401 is fixed to one end of the outer shell 47 near the pressing plate 41. A snap button 42 is fixed to the top cover 401, and the pressing plate 41 is pressed and locked onto the snap button 42.

[0027] The pressing and locking of the pressing column 40 is achieved by setting the snap button 42 and the pressing plate 41.

[0028] In this embodiment, the pressing post 40 is provided with a storage groove 43 for the insertion post 44 to be inserted into. The storage groove 43 is provided with a telescopic spring 49 that abuts against the insertion post 44. The storage groove 43 is provided with a sliding groove 402 along the axial direction of the pressing post 40. The insertion post 44 is fixed with a protrusion located in the sliding groove 402.

[0029] A positioning post 45 is fixed to the end of the plug post 44 away from the pressing post 40. The positioning post 45 and the pressing post 40 are elastically connected by a return spring 48.

[0030] When in use, the pressing post 40 is pressed and locked, and the return spring 48 is squeezed. At this time, the positioning post 45 abuts against the guide rail 5, and the telescopic spring 49 is squeezed. When the positioning hole is aligned with the positioning post 45, the telescopic spring 49 pushes the positioning post 45 into the positioning hole, thereby realizing the positioning of the guide rail 5. When it is necessary to remove it, the pressing post 40 is pressed again, and the telescopic spring 49 drives the pressing post 40 to return to its original position. The pressing post 40 drives the positioning post 45 to disengage from the positioning hole through the insertion post 44.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
