The utility model belongs to the technical field of electric hoisting devices, provides an electric hoisting device for excavating a contact passage pump room, and aims to solve the problems of low manual excavation speed, high labor intensity and influence on procedures and safety when the contact passage pump room is excavated by adopting an undercutting method. The electric hoisting device comprises I-shaped steel frames arranged at the two ends of the pump room, wherein an I-shaped steel beam is arranged at the top ends of the I-shaped steel frames; an electric hoist is suspended on the I-shaped steel beam; each I-shaped steel frame consists of two support frames and a transverse beam arranged on the support frames; the support frames are fixed on support grating steel frames built at the bottom of a contact passage; one end of the I-shaped steel beam is fixed on a temporary support built during contact passage construction; the electric hoist is a single-hook suspension electric hoist. The electric hoist is used for realizing vertical lifting and horizontal transportation, and mechanical work is adopted for replacing manual construction in the narrow space, so that the construction process is accelerated, and the investment of labor force is reduced; the electric hoisting device can be applied in narrow structures such as the contact passage pump rooms and water-collecting wells, and is simple in structure and remarkable in effect; the hoisting operation safety is ensured.
