The invention discloses a mounting and adjusting device for pouring of a solid propellant combustion chamber. The mounting and adjusting device comprises a pouring cylinder which is cylindrical and isprovided with the hollow interior, and the bottom of the pouring cylinder is provided with a hydraulic lifting platform. A plurality of guiding grooves are uniformly distributed in the side wall of the pouring cylinder in the axial direction, a plurality of annular grooves are distributed in the side wall of the pouring cylinder in the radical direction, and the guiding grooves and the annular grooves are vertically formed in the inner side of the side wall in a staggered mode. The mounting and adjusting device further comprises a bearing disc, the bottom of the bearing disc is connected witha bearing beam, and the center of the bearing beam is provided with a bearing. The mounting and adjusting device is reasonable in structure, reliable in work and easy to operate, various potential safety hazards are completely eliminated, the number of tools is decreased, and the production cost and management cost of enterprises are greatly reduced.

Mounting and adjusting device for pouring of solid propellant combustion chamber

The utility model relates to electromagnetic crane equipment, in particular to a rotating mechanism of an electromagnetic crane. The rotating mechanism comprises a rotating beam; a slewing bearing is arranged at the bottom of the rotating beam and is connected with a connecting support; the connecting support is connected with an electromagnetic suspended beam; an electromagnet connecting piece and an electromagnet are arranged on the electromagnetic suspended beam; the rotating beam is formed by a cross beam and a longitudinal beam in a crossing way; movable pulley are arranged at two ends of the cross beam and the longitudinal beam; the rotating beam is connected with a principle machine of the crane by steel wire ropes on the movable pulleys; a speed reducer is arranged on the rotating beam; a gear is arranged on the speed reducer; a gear is arranged on the inner surface of the slewing bearing; and the gear of the speed reducer is meshed with the gear on the inner surface of the slewing bearing. The rotating mechanism has the advantages that the rotating mechanism is not easy to sway during hoisting, hoisting is stable and labor-saving, the crane has high acting efficiency, etc.
