The invention discloses a threaded sleeve locking type tensioning control device, and relates to the field of mechanical tensioning. According to the technical scheme, the threaded sleeve locking type tensioning control device comprises an outer cylinder body, an inner cylinder body and a pull rod; an inner cavity of the outer cylinder body is in sliding fit with the inner cylinder body; the outer cylinder body is provided with a first thrust piece for pushing the inner cylinder body backwards or forwards; an inner cavity of the inner cylinder body is in sliding fit with an inner piston, the inner piston is connected with the rear end of the pull rod, and a pre-pressing spring is arranged between the inner piston and the front end of the inner cylinder body. A threaded sleeve locking assembly is arranged between the inner cylinder body and the outer cylinder body. By the adoption of the threaded sleeve locking type tensioning control device, the object to be tensioned can be tensioned automatically or manually. The threaded sleeve locking type tensioning control device is simple in structure, strong in tensioning force, high in reliability, sustainable, convenient to remotely check the working state of the threaded sleeve locking type tensioning control device, and suitable for anti-slip locking of railway vehicles.
