Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As depicted in figs. 1 and 2: the utility model includes hook 1, pulley 5, wirerope 6 and roller 7, and the hook is fixed
In one end of the wirerope, the pulley is fixed on crown 3, the other end of the wirerope after the pulley with institute
It states roller to be intertwined and connected, the crown, which is located above the hook, is provided with limit for height controller 2, turns in the pulley
It is provided with tension sensor 4 on axis, brake block 8 is provided in the roller outer circle, one end and the cylinder of the brake block are fixed
One end of connection, the other end of the brake block and the connecting rod 11 is rotatablely connected, and the middle part of the connecting rod passes through the torsion axis 9
The piston rod 19 of rotation connection, the other end of the connecting rod and the cylinder 10 is rotatablely connected, and is provided with starting on the cylinder
Solenoid valve and solenoid valve is closed, release unloading valve solenoid valve and brake unloading valve is additionally provided on the cylinder, the cylinder connects
Cutting solenoid valve upstream is connect, the automatically controlled end of the air motor connects microcomputer host, the signal acquisition of the microcomputer host
End is electrically connected the limit for height controller and the tension sensor, the control signal output of the micro computer auxiliary agent electrically connect
Connect the starting solenoid valve 16, brake unloading valve 21 and the closing solenoid valve 17, release unloading valve 20.
As an improvement, the output end of the air motor is additionally provided with cutting solenoid valve 18.The microcomputer host 14 is set
It is equipped with display 13 and combined aural and visual alarm 12.
Working principle: when lifting, start winch motor 15, roller 7, which starts turning, drives wirerope 6 and the rotation of pulley 5 to draw
