Description

Technical Field

[0001] The utility model relates to the technical field of automated equipment for a prestressed concrete pipe pile production line, in particular to a pile hanger with automatic identification and automatic adsorption. Background Art

[0002] Suction cup slings are very important transfer equipment in the production process of pipe piles. All types of pipe piles can be transferred by suction cup slings. Since the production of concrete pipe piles adopts assembly line operation, the suction cup slings of pipe piles configured on the assembly line are required to have high production efficiency, especially in the demoulding and transportation process:

[0003] (1) The pile crane using traditional lifting equipment cannot automatically demould, and ground workers are required to help with demoulding and lifting.

[0004] (2) When demolding the pile, the temperature of the pile is relatively high because the pipe mold with the pile has just been lifted out of the high-temperature steam curing tank. If traditional pipe pile lifting equipment is used, the working environment of the workers working near the pile is high in temperature and humidity, which can easily cause safety accidents such as burns to the workers.

[0005] (3) The traditional pipe pile lifting device requires the driver to position and locate the pile in the cab, and then lift the pile manually after demoulding on the ground. This is not only labor-intensive but also has low production efficiency, which affects the output of pipe pile production.

[0006] (4) If ordinary vacuum suction cup lifting devices are used, they can generally only adapt to concrete pipe piles of one specification, and cannot meet the needs of pipe piles of different diameters and lengths, let alone bamboo piles (bamboo piles refer to pipe piles with a bulge in the middle that looks like a bamboo node), and have poor adaptability.

When the suction cup assembly contacts the top of the pile, it moves vertically along the guide rod to make multiple groups of the suction cup assemblies float in contact with different parts of the pile.

[0014] Preferably, the object detection switch detects the displacement distance of the guide rod, and each group of the suction cup assemblies is individually configured with an indicator light electrically connected to the object detection switch.

[0017] Preferably, the vacuum pump device is provided with a vacuum pump pressure sensor for detecting the vacuum suction force of the vacuum pump device.
