Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments thereof.
As shown in fig. 1 and 4, an electromagnetic portal crane includes a crane body 10, the crane body 10 includes a gantry 12, a plurality of electromagnetic hanging beams 30 are arranged below the gantry 12, the axial direction of the electromagnetic hanging beams 30 is perpendicular to the plane where the gantry 12 is located, a plurality of trolleys 13 are arranged on the beam of the gantry 12, each trolley 13 cooperates with one electromagnetic hanging beam 30, and specifically, the electromagnetic hanging beam comprises: the trolley 13 is suspended with two movable pulley beams 15 through a traction power part, the movable pulley beams 15 are fixed on the electromagnetic hanging beam 30, and the electromagnetic hanging beam 30 can be lifted under the traction of the traction power part.
Referring to fig. 1-2, the lower portion of the electromagnetic suspension beam 30 is connected to a plurality of electromagnetic chucks 91, and the electromagnetic chucks 91 are used for connecting the steel rail 90.
Referring to fig. 1, in order to prevent the electromagnetic suspension beam 30 from shaking, a vertical guide rail 102 is fixed on the gantry 12, a guide post 101 is fixed on the electromagnetic suspension beam 30, and the guide post 101 is clamped in the vertical guide rail 102 and can slide therein, so that a moving pair is formed between the guide post 101 and the vertical guide rail 102.
Referring to fig. 2, the electromagnetic suspension beam 30 is connected to the electromagnetic chuck 91 via a rope 32 in order to provide a slight adjustment between the rail 90 and the electromagnetic chuck 91.
As shown in fig. 5-7, the traction power component is a traction motor 131, the traction motor 131 is fixed on the trolley 13, and is provided with two output shafts 132, each output shaft 132 is connected with a winding drum 134 through a speed reducer 133, a steel wire rope 136 is wound on the winding drum 134, the free end of the steel wire rope 136 is connected on a fixed pulley block 135 through a direction-changing pulley block 137 and a movable pulley block 16, the fixed pulley block 135 and the direction-changing pulley block 137 are arranged on the trolley 13, and the movable pulley block 16 is arranged on the movable pulley beam 15.
