An upper vertical elbow of a try-type bridge frame comprises a groove rack and a protecting cover. The groove rack is integrally designed to be L-shaped, and chamfers are connected between two openings of the groove rack; the groove rack is movably connected with the protecting cover; a corrosion prevention coating layer is arranged on the surface of each of the groove rack and the protecting cover. The upper vertical elbow has the advantages of being simple in structure, simple and convenient to use and capable of effectively lowering cable abrasion and decreasing probability of wire breakage inside the cable in elbows.
