Supporting and hanging frame for building machinery and electricity

The utility model provides a building electromechanical support hanger which comprises a base, supports are symmetrically and fixedly connected to the base, the other ends of the two supports are both arranged on a wall beam, a limiting block is fixedly connected to the wall beam, a buffering mechanism is fixedly connected to the position, below the limiting block, of the base, and an air pipe can be connected into the buffering mechanism in a contact mode. Air cylinders are symmetrically and fixedly connected to the portions, on the two sides of the buffering mechanism, of the wall beam, the driving ends of the air cylinders are fixedly connected with connecting rods, and the connecting rods are in contact connection with the buffering mechanism. The air pipe is limited through the combination of the buffering mechanism and the limiting block, the buffering mechanism can play a buffering role when the air pipe is vibrated, the air pipe is protected, meanwhile, the sliding mechanism is driven by the air cylin
