In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0018] like Figure 1 , Figure 2 As shown, the present invention provides a locomotive drive shaft box bearing hanger, including an upper bracket assembly 2 and a lower bracket assembly 3;

[0019] like Figure 3 As shown, the upper bracket assembly 2 includes a sleeve 2-1, the top of the sleeve 2-1 has a lifting ring 1, the side of the sleeve has a longitudinal sliding hole 2-2 that passes through the sleeve 2-1, and the outer wall of the sleeve 2-1 is evenly distributed with four groups of upper mounting plates 2-4 around its axis, and each group of upper mounting plates 2-4 includes two upper mounting plates 2-4 that are spaced apart;

[0020] like Figure 4 As shown, the lower bracket assembly 3 includes a longitudinal round rod adapted to the sleeve 2-1, the upper part of the longitudinal round rod has a sliding pin shaft connection hole 3-1, and the lower end of the longitudinal round rod is evenly distributed around its axis with four groups of four lower mounting plates 3-2 corresponding to the upper mounting plates 2-4, each group of lower mounting plates 3-2 includes two lower mounting plates 3-2 arranged at intervals;

[0021] like Figure 1 , Figure 2 , Figure 5As shown, the upper end of the longitudinal round rod is deeply inserted into the sleeve 2-1, and the longitudinal round rod and the sleeve 2-1 are slidably connected by the sliding pin bolt 2-3 passing through the longitudinal sliding hole 2-2 and the sliding pin connecting hole 3-1; each group of upper mounting plates 2-4 corresponds to a connecting support plate 4, and the connecting support plate 4 is composed of an upper strip plate 4-4, a middle strip plate 4-5 and a lower strip plate 4-6 connected in sequence, and the upper strip plate 4-4 has a long sliding hole 4-3, and the connection between the middle strip plate 4-5 and the lower strip plate 4-6 has a lower shaft pin mounting hole. The mounting hole 4-2, the lower end of the lower strip 4-6 has a hook plate 4-1, the upper end of the upper strip 4-4 and the lower end of the lower strip 4-6 are inclined toward the outside away from the sleeve 2-1, the upper strip 4-4 and the upper mounting plate 2-4 are slidably connected by passing through the upper sliding hole 4-3 and the upper pin bolt 2-6 on the side wall of the upper mounting plate 2-4, and the connecting support plate 4 and the lower mounting plate 3-2 are rotationally connected by passing through the lower pin mounting hole 4-2 and the lower pin bolt 3-3 on the side wall of the lower mounting plate 3-2.
