The invention relates to the technical field of elevators, and discloses a screw elevator middle reinforcing device which comprises two sets of guide rails which are arranged side by side in a spaced mode, the tops of the two sets of guide rails are connected through a first cross beam, and the bottoms of the two sets of guide rails are connected through a second cross beam; the top of the screw rod is fixedly connected with the first cross beam, and the bottom of the screw rod is fixedly connected with the second cross beam; the lifting platform assembly is arranged between the two groups of guide rails in a sliding manner and is in threaded connection with the screw rod; the lifting driving assembly is used for driving the lifting platform assembly to move on the screw rod; the reinforcing beam is arranged between the first cross beam and the second cross beam, and two ends of the reinforcing beam are respectively connected with the two groups of guide rails; the reinforcing assembly is arranged on the reinforcing beam, and the reinforcing assembly can be used for clamping the screw rod; when the lifting platform assembly is close to the reinforcing assembly, the reinforcing assembly retracts to avoid the lifting platform assembly; and when the lifting platform assembly is far away from the reinforcing assembly, the reinforcing assembly clamps the screw rod. By arranging the reinforcing assembly, the screw can be clamped by the reinforcing assembly, shaking of the screw is avoided, the riding comfort is improved, and when the lifting platform assembly gets close to the reinforcing assembly, the reinforcing assembly can retract to avoid vertical movement of the lifting platform assembly.
