MOBILE SUBSTATION Russian patent published in 2022 - IPC E21F13/00 B62B3/00 H02B5/00 

FIELD: tunnel construction.

SUBSTANCE: invention is intended for providing a high-voltage power source for tunnel construction. The mobile substation contains a box-type substation (1) and a trolley (2) for transporting the mobile substation (1). The trolley (2) contains a body (2-1) and a roller (2-2) for moving it. The body (2-1) is equipped with a base plate (3) for transporting a box-type substation (1) and a rotating shaft (3-1), each of the two ends of the rotating shaft (3-1) are respectively connected to the base plate (3) and the body (2-1) ensuring the rotation of the base plate (3) around the rotating shaft (3-1). The support surface (3-3) of the base plate (3) is larger in the length direction than in the transverse direction, the connection between the base plate (3) and the rotating shaft (3-1) is made in the middle of the transverse direction of the base plate (3), and located at one end of the center line in the direction of the length of the bearing surface (3-3). In this case, the distance to the end of the support surface (3-3) is 1/8-3/8 of the length of the center line. Maneuvering wheels (3-4) are located on one side of the base plate (3-1). On the body (2-1) there are several L-shaped fixed locks (4).

EFFECT: improving the safety and maneuverability of a mobile substation.
