The invention discloses a multifunctional hoisting device for a heat expanding steel pipe. The multifunctional hoisting device comprises a hoisting machine body and a slide shaft. Two slide shafts are installed at the right end of the hoisting machine body and are vertically parallel. A control panel is installed on the lower surface of the front end of the hoisting machine body. A slide plate is installed at the right ends of the slide shafts. The right end of the slide plate is connected with a bearing shaft in a clamped mode. A telescopic plate is welded to the right end of the bearing shaft. A steel pipe containing box is welded to the right end of the telescopic plate. An inner cavity of the steel pipe containing box is divided into two independent spaces by installing a partition plate. A gravity sensor is arranged at the lower end of the inner cavity of the steel pipe containing box. The output end of the control panel is electrically connected with the input end of a controller. The multifunctional hoisting device is easy and convenient to use, can well protect a steel pipe in the use process, provides good safety performance for a user, and is more user-friendly in the use process.
