The portal frame 3 comprises two telescopic upright posts 31, a walking base is arranged at the bottom of each telescopic upright post 31, and a sliding rail matched with the walking base is arranged on the platform foundation 1. The top of the two telescopic uprights 31 is provided with a cross beam 32. The beam 32 is provided with a motor 33 and a shaft 35. The rotating shaft 35 is arranged above the cross beam 32 in parallel through bearing blocks. A motor 33 is fixed to the cross beam 32, the motor 33 is used for driving the rotating shaft 35 to rotate, the motor 33 is in transmission connection with the rotating shaft 35 through a belt and a belt pulley 34, the belt is not shown, and the belt pulley 34 matched with the belt is installed on the rotating shaft 35. Gear diverters 36 are provided at both ends of the cross beam 32. The gear deflector 36 is connected to an end of the rotary shaft 35, while the gear deflector 36 is also connected to a vertically disposed first screw 37. The other end of the first screw rod 37 is connected with a fixed section of the telescopic upright 31 in a matched manner. When the motor 33 drives the rotating shaft 35 to rotate, the rotating shaft 35 drives the first lead screw 37 to rotate through the gear steering device 36, and the first lead screw 37 and a fixed section of the telescopic upright 31 move axially relatively, so that the gear steering device 36, together with the cross beam 32 and a movable section of the telescopic upright 31, achieve a lifting effect.
