The invention belongs to the technical field of transmission, and particularly relates to a jacking transmission and brake assembly. The jacking transmission and brake assembly comprises a jacking transmission mechanism and a brake mechanism; the jacking transmission mechanism comprises a base frame, a driving wheel, a driven wheel, a linkage shaft, a worm wheel and a worm, the driving wheel is rotationally matched with the base frame and meshes with the driven wheel, the driven wheel and the worm wheel are coaxially mounted through the linkage shaft for linkage, the linkage shaft is rotationally matched with the base frame, the worm wheel is in transmission connection with the worm, and the worm is vertically and fixedly mounted; and the braking mechanism is used for braking reverse transmission of the jacking transmission mechanism under the pressure action of external force. The jacking transmission and brake assembly, the operation of lifting and braking after lifting to the targetposition is achieved; and by adopting transmission fit of the worm wheel and the worm, jacking precision is high.
