Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically a vacuum suction cup hoisting device. Background Technology

[0002] Vacuum suction cup lifting equipment utilizes the principle of vacuum, that is, using vacuum negative pressure to "adsorb" workpieces to achieve the purpose of lifting workpieces. After the vacuum pump is started, the air inside the suction cup is sucked out, forming a vacuum state with a certain pressure. At this time, the air pressure inside the suction cup is lower than the atmospheric pressure outside the suction cup, and the workpiece is lifted under the action of external pressure. However, existing suction cup lifting equipment cannot change the spacing between suction cups, making it difficult to adjust according to the items to be lifted, and its use is quite limited.
