The invention discloses a tilting type straight-bar pantograph device. The tilting type straight-bar pantograph device is mainly composed of an underframe, an air bag, a steel wire rope, a fan-shaped adjusting plate, a rotating shaft, a rotating arm, a straight bar, a Y-shaped supporting head, a hanging device, a pantograph bow frame and a tubular sliding plate. When a pantograph ascending button is pressed down, an electromagnetic valve is powered up, compressed air enters the air bag so that the air bag can be expanded and lifted, the steel wire rope is driven to pull the straight bar to make a pantograph ascend at a certain angle, and the tubular sliding plate on a pantograph bow makes contact with a contact line to be powered up. When a pantograph descending button is pressed down, the electromagnetic valve is powered off, the compressed air is cut off, the air bag exhausts air, and the pantograph descends quickly under the action of self weight to fall onto a rubber stopping block. The tilting type straight-bar pantograph device is simple in structure; compared with a traditional pantograph, more than 80% of parts are reduced, a complex frame structure and auxiliary hinge devices of the frame structure are omitted, and the weight of the device only accounts for 1/4 to 1/3 of the weight of the traditional pantograph; air resistance is small, and vibration is low; the device can be in close contact with the contact line at any height, the contact resistance is small, and arcs can be greatly reduced.
