AI Technical Summary
The bolt connections of existing forged aluminum load-bearing cable support clamps are prone to loosening, resulting in insufficient reliability.
A high-strength wire clamp device is adopted, which distributes stress through the structural cooperation of the plug sleeve and the annular groove, and uses a reinforcing frame and connecting ear to lock and fix the upper and lower mounting seats to avoid stress concentration on the screw.
It improves the reliability of the support clamp, prevents wobbling caused by loose nuts, and extends its service life.

Abstract
Claims
1. A forged aluminum messenger cable anchor support clamp for a railroad, characterized by: The device includes a high-strength wire clamp device (1), which comprises an upper clamp (11), an upper mounting base (12), a lower clamp (13), a lower mounting base (14), a screw (15), a nut (16), a plug-in sleeve (17), and an annular groove (18). The upper clamp (11) is integrally provided with the upper mounting base (12) on both sides, and the lower clamp (13) is provided below the upper clamp (11). The lower clamp (13) is integrally provided with the lower mounting base (14) on both sides. The screw (15) is composed of... The screw passes through the mounting holes inside the lower mounting base (14) and the upper mounting base (12) from bottom to top, and the top of the screw (15) is tightened with a nut (16) to lock the upper mounting base (12) and the lower mounting base (14) together. The lower sleeve (13) is assembled and fixed on the lower part of the upper sleeve (11). The top surface of the lower mounting base (14) is provided with a plug sleeve (17), and the bottom surface of the upper mounting base (12) is provided with an annular groove (18). The plug sleeve (17) is movably nested into the inner side of the annular groove (18).
2. The forged aluminum messenger seat support clamp for a railway of claim 1, wherein: The height of the plug sleeve (17) is 5-15mm, and the depth of the annular groove (18) matches the height of the plug sleeve (17).
3. The forged aluminum messenger seat support clamp for a railway of claim 1, wherein: The plug sleeve (17) and the lower mounting base (14) are integrally cast.
4. The forged aluminum load-bearing cable support clamp for railways according to claim 1, characterized in that: The upper mounting base (12) and the lower mounting base (14) are movably fitted with reinforcing frames (19). The upper and lower edges of the outer side of the reinforcing frames (19) are symmetrically provided with connecting ears (191). The two sets of connecting ears (191) are respectively attached to the outside of the upper mounting base (12) and the lower mounting base (14). The screw (15) is longitudinally inserted through the inside of the connecting ears (191) to lock and fix the connecting ears (191) with the upper mounting base (12) and the lower mounting base (14) into one piece.
5. The forged aluminum messenger seat support clamp for a railway of claim 4, wherein: The inner side of the reinforcing frame (19) is arc-shaped.
6. The forged aluminum messenger seat support clamp for a railway of claim 4, wherein: The reinforcing frame (19) and the connecting ear (191) are made of forged aluminum.
