For achieving the above object, the technical scheme that the utility model is taked is: a kind of crane hanging beam automatic level control device, it is installed on the hanging beam, and it comprises a front rake switch, a casterangle switch, two contactless switch KA1, two contactless switch KA2, a contactless switch 1KA1, a contactless switch 1KA2, a contactless switch 2KA1, a contactless switch 2KA2, a contactless switch 1KA6, a contactless switch 1KA7, a contactless switch 2KA6 and contactless switch 2KA7; Wherein, described front rake switch and casterangle switch lay respectively at the two ends of hanging beam, and both are electrically connected on the Switching Power Supply by a power supply changeover device; Phase and connecing after be connected in series with a contactless switch KA2, contactless switch 2KA1, contactless switch 2KA7 again after one contactless switch KA1, contactless switch 1KA2, the contactless switch 1KA6 serial connection, and be electrically connected on the described Switching Power Supply; Phase and connecing after be connected in series with another contactless switch KA2, contactless switch 2KA2, contactless switch 1KA7 again after another contactless switch KA1, contactless switch 1KA1, the contactless switch 2KA6 serial connection, and be electrically connected on the described Switching Power Supply.
Crane hanging beam automatic level control device of the present utility model further is set to: it is provided with for control front rake switch, the casterangle switch is enabled or inactive mask switch.
Crane hanging beam automatic level control device of the present utility model also is set to: described contactless switch is normally open contactor.
Compared with prior art, the utlity model has following beneficial effect: crane hanging beam automatic level control device of the present utility model can detect heeling condition automatically when the hanging beam run-off the straight, and the lifting velocity of control suspension hook adjusts hanging beam to level, and hanging beam is operated steadily, and uses safety.
Description of drawings
Fig. 1 is the schematic diagram of crane hanging beam automatic level control device of the present utility model.
Fig. 2 is the scheme of installation of crane hanging beam automatic level control device of the present utility model.
The specific embodiment
See also shown in Figure of description 1 and the accompanying drawing 2, the utility model is a kind of crane hanging beam automatic level control device 100, it is installed on the hanging beam 9, and it comprises a front rake switch 11, a casterangle switch 12, two contactless switch KA1, two contactless switch KA2, a contactless switch 1KA1, a contactless switch 1KA2, a contactless switch 2KA1, a contactless switch 2KA2, a contactless switch 1KA6, a contactless switch 1KA7, a contactless switch 2KA6, a contactless switch 2KA7 and mask switch 4.
Wherein, described hanging beam 9 two ends are provided with left side suspension hook 91 and right side suspension hook 92.
Described front rake switch 11 and casterangle switch 12 lay respectively at the two ends of hanging beam 9, and both are electrically connected on the Switching Power Supply 3 by a power supply changeover device 2, and this power supply changeover device 2 turns direct current transducer for exchanging.Described mask switch 4 is used for control front rake switch 11, casterangle switch 12 is enabled or stop using, and when mask switch 4 was stopped using, hanging beam 9 can adopt manual control.
Further, phase and connecing after wherein be connected in series with a contactless switch KA2, contactless switch 2KA1, contactless switch 2KA7 again after a contactless switch KA1, contactless switch 1KA2, the contactless switch 1KA6 serial connection, and be electrically connected on the described Switching Power Supply 3.Phase and connecing after be connected in series with another contactless switch KA2, contactless switch 2KA2, contactless switch 1KA7 again after another contactless switch KA1, contactless switch 1KA1, the contactless switch 2KA6 serial connection, and be electrically connected on the described Switching Power Supply 3.Described contactless switch is normally open contactor.
