The invention discloses a lifting type construction platform for constructional engineering. The lifting type construction platform comprises a bottom plate, wheels, a support plate, a rotating lead screw, a support plate, a sliding block, a gear, a toothed belt, a feeding assembly, a reset spring, a clamping hook, a support rod, a rotating shaft and a third motor. According to the invention, teeth are matched with the toothed belt, the vertical up-down movement of the support plate can be realized, by matching with the clamping hook, when the motor fails, the support plate does not slip, safety of constructors is guaranteed, the safety performance of the lifting platform is greatly improved, extensible sliding plates are arranged on the two sides of the bottom plate, the support range ofthe bottom side can be expanded, through the effect of the rotating lead screw, the stability of the lifting platform can be guaranteed at the non-platform operation position, the situation that the lifting platform inclines is avoided, the lifting platform can be better fixed, a feeding structure is arranged on the side edge of the lifting platform, construction materials and construction waste materials can be conveniently conveyed, and the construction efficiency can be greatly improved.
