Abstract
Description
Technical Field
[0001] This utility model relates to the field of rapid docking and positioning technology, and in particular to a rapid docking and positioning device for railway protective net frame and net sheet. Background Technology
[0002] In the field of railway transportation infrastructure construction, railway safety nets are a key protective structure for ensuring line safety. The quality of the docking and positioning between the frame and the mesh directly affects the protective performance and construction efficiency. Currently, there are still significant technical bottlenecks in related docking and positioning technologies. First, existing devices generally adopt a non-independent design, requiring structural modifications such as drilling and welding on the frame or mesh body. For example, pre-drilling threaded holes in the frame to install clamping components or welding positioning ear plates to the edge of the mesh not only damages the original mechanical structure of the safety net but also makes the device incompatible with different standard safety net specifications, resulting in poor versatility and difficulties in modification. The process increases pre-construction processing time and reduces overall construction efficiency. Secondly, existing devices mostly rely on single-dimensional clamping and positioning mechanisms, applying clamping force only in a single horizontal or vertical direction. For example, if bolts are used to press the edge of the mesh for positioning, it is easily affected by construction vibration and changes in mesh tension, requiring repeated disassembly and adjustment. At the same time, the device lacks an extension and adaptation structure, requiring the replacement of the entire clamping module when facing different specifications of frames and meshes, increasing the spare parts inventory cost for construction units. Moreover, in outdoor railway environments, the fixed structure is prone to rust and jamming, requiring subsequent maintenance to be forcibly dismantled, further increasing maintenance costs and labor time.

[0022] Please see the appendix Figure 1 - Appendix Figure 7This utility model provides an embodiment of a quick-connection and positioning device for railway protective netting frame and mesh panel, including a frame component 1, a mesh panel component 2 disposed on the upper surface of the frame component 1, a left base block 3 and a right base block 11 disposed on one outer surface of the frame component 1, each of the left base block 3 and the right base block 11 having a limiting groove 4, a first fixing hole 5 being provided on one outer wall of the left base block 3, a thick telescopic rod 8 and a vertical adjustment clamping mechanism 9 being welded into the first fixing hole 5, and a second fixing hole 6 being provided on one outer wall of the left base block 3 and the right base block 11, a thin telescopic rod 7 being welded into the second fixing hole 6; the vertical adjustment clamping mechanism 9 includes a first clamping arm 901, a first clamping groove 902, a vertical threaded hole 903, and a first connecting...

A right base block 11 is located at the end of the vertical fixing rod 912. A first fixing hole 5 is formed on one side of the outer wall of the right base block 11. The end of the vertical fixing rod 912 is welded into the first fixing hole 5, thus fixing the vertical adjustment clamping mechanism 9 to the right base block 11, forming a vertical linkage structure between the left base block 3 and the right base block 11. A first clamping groove 902 is formed on the first clamping arm 901. A vertical threaded hole 903 is formed on one side of the outer wall of the first clamping arm 901. A vertical threaded hole 903 is formed on one side of the outer surface of the first clamping arm 901. A first connecting hole 904 and a vertical threaded hole 903 are internally threaded to a vertical threaded screw 905. One end of the vertical threaded screw 905 is provided with a first swing handle 906. The two ends of the first swing handle 906 are respectively provided with a first through groove 907 and a first through hole 908. One end of the vertical threaded screw 905 is welded into the first through groove 907, ensuring that when the first swing handle 906 rotates, it synchronously drives the vertical threaded screw 905 to drive the first clamping arm 901 to move vertically.

The end of the horizontal fixing rod 1012 is welded to the first connecting hole 904 to fix the horizontal adjustment clamping mechanism 10 and the first clamping arm 901, forming an integrated structure for vertical and horizontal adjustment.The second clamping arm 1001 has a second clamping groove 1002. A transverse threaded hole 1003 is formed on one outer wall of the second clamping arm 1001. A second connecting hole 1004 is formed on one outer surface of the second clamping arm 1001.

One end of the transverse threaded screw 1005 is welded into the second through groove 1007, and the other end is welded into the second connecting hole 1004. A thick telescopic rod 8 ensures that when the second swing handle 1006 rotates, it drives the transverse threaded screw 1005 to move the second clamping arm 1001 laterally, and the thick telescopic rod 8 provides lateral support. A second rotating shaft 1009 is provided inside the second through hole 1008, and a second anti-slip handle 1010 is provided inside the second rotating shaft 1009. A second linkage shaft 1011 is provided at the end of the transverse threaded screw 1005, and a transverse fixing rod 1012 is provided on one side of the second linkage shaft 1011. The second rotating shaft 1009 allows the second anti-slip handle 1010 to rotate, and the second linkage shaft 1011 prevents the transverse threaded screw 1005 from swaying radially.
[0023] Working Principle: Using this invention, firstly, align the left base block 3 and right base block 11 of the device with the two lower corners of the frame member 1, respectively, so that the limiting grooves 4 on the left base block 3 and right base block 11 are completely fitted with the outer walls of the two lower corners of the frame member 1. The groove structure of the limiting grooves 4 achieves initial positioning between the device and the frame member 1. At this point, the device uses the two lower corners of the frame member 1 as a reference to form a stable installation foundation, without requiring any structural modifications to the frame member 1 itself. The horizontal adjustment clamping mechanism 10 of the device is distributed corresponding to the two upper corners of the frame member 1, and the end of the horizontal fixing rod 1012 of the horizontal adjustment clamping mechanism 10 is welded to the first connecting hole 904 of the left base block 3, forming a linkage between the lower base and the upper clamping mechanism. The mechanism involves rotating the second anti-slip handle 1010 of the horizontal adjustment clamping mechanism 10. This handle, via the second rotating shaft 1009 fixed within the second through hole 1008, drives the second swing handle 1006 to rotate. Since one end of the horizontal threaded screw 1005 is welded to the second through groove 1007 of the second swing handle 1006, and the horizontal threaded screw 1005 is threadedly connected to the horizontal threaded hole 1003 of the second clamping arm 1001, the rotation of the second swing handle 1006 drives the horizontal threaded screw 1005 to move axially, thereby causing the second clamping arm 1001 to extend and retract laterally until the second clamping groove 1002 of the second clamping arm 1001 precisely engages with the two corners of the upper end of the frame piece 1, completing the lateral positioning of the upper corners of the frame piece 1. During this process, the two… The thin telescopic rods 7, which are respectively welded to the second fixing holes 6 of the left base block 3 and the right base block 11, will extend and retract synchronously with the lateral extension and retraction of the horizontal adjustment clamping mechanism 10, ensuring the consistency of the lateral adjustment of the device and preventing the corners of the frame piece 1 from being offset by force. Align the four corners of the mesh piece 2 with the four corners of the frame piece 1, and then rotate the first anti-slip handle 910 of the vertical adjustment clamping mechanism 9. The first rotating shaft 909 in the first through hole 908 drives the first swing handle 906 to rotate. Since one end of the vertical threaded rod 905 is welded to the first through groove 907 of the first swing handle 906, and the vertical threaded rod 905 is threadedly connected to the vertical threaded hole 903 of the first clamping arm 901, the rotation of the first swing handle 906 will drive the vertical threaded rod 905 axially. The movement causes the first clamping arm 901 to extend and retract vertically, so that the first clamping groove 902 of the first clamping arm 901 simultaneously engages with the four corners of the mesh piece 2 and the two upper corners of the frame piece 1, achieving vertical coordinated positioning of the mesh piece 2 and the frame piece 1. During this process, the thick telescopic rod 8, which is welded to the first fixing hole 5 of the left base block 3 and the second connecting hole 1004 of the horizontal adjustment clamping mechanism 10 at both ends, will extend and retract synchronously with the vertical extension and retraction of the vertical adjustment clamping mechanism 9, ensuring the stability of the vertical adjustment of the device and preventing vertical misalignment between the mesh piece 2 and the frame piece 1. The horizontal threaded screw 1005 and the vertical threaded screw 905 maintain the clamping force on the second clamping arm 1001 and the first clamping arm 901 through the self-locking characteristics of the threads.The limiting groove 4, the second clamping groove 1002, and the first clamping groove 902 of the left base block 3 and the right base block 11 form a triple clamping structure. Combined with the structural constraints of the first linkage shaft 911, the second linkage shaft 1011, the vertical fixing rod 912, and the horizontal fixing rod 1012, this ultimately achieves rapid and error-free docking and positioning of the frame piece 1 and the mesh piece 2.
