摘要（英）：

The utility model discloses a chimney lifting device of an oil and gas field heating device. The technical problem of the heating device is completely solved. A support and a chimney base are arranged on a prying base of the lifting device. The support is hinged to a lengthening rod which is provided with a hand winch. A fixed pulley is arranged at the top end of the lengthening rod. A supporting base for supporting the chimney is arranged on the bottom face of the chimney base. The chimney is provided with a movable pulley. The bottom end of the chimney is connected with a chimney foundation through a hinged flange. One end of a steel wire rope is connected with the hand winch, and the other end is wound through the fixed pulley and the movable pulley and is fixed at the top of the lengthening rod. The lifting device does not leave a furnace body during a transporting process, easily-disassembled parts are avoided, losing can be avoided, the structure is simple and reliable, and maintaining is convenient.
