Cable collection tube is placed on the contact crossbeam, and the height and position of plane certain distance on the crossbeam is installed the friction rotating disk over against the cable collection tube center, increases friction rotating disk cornerite with carrying roller, and cable arrives in the cable trough on ground by other guider again.The normal speed of friction rotating disk and cable collection tube guider is set at a little more than the cart normal speed, and the normal speed of cable collection tube guider is a little more than the setting speed of friction rotating disk.
The friction rotary speed is regulated by adjustable frequency motor, and to adapt to the cart friction speed, cable collection tube speed can be fixed by variable frequency adjustment.Stream oriented device all is equipped with the magnetic hysteresis coupling, be used for the asynchronous caused speed discrepancy of compensation speed, guarantee that cable is by certain moment of torsion and the speed drive that needs, the friction rotating disk uses the magnetic hysteresis coupling than high pulling torque, the magnetic hysteresis coupling moment of torsion that the cable collection tube guider uses cable is involved in smooth-goingly or pull out cable collection tube just can, thereby much smaller.
2. the folding and unfolding of container crane sling cable:
On the basis of former use cable storage frame mode, one guider is installed, and the setting speed of this device is generally 110% lifting velocity a little more than main lifting velocity, magnetic hysteresis coupling moment of torsion is adjusted according to the main lifting velocity of difference, and the assurance cable correctly enters in the tube or from tube in order emits.
At present, suspender cable core number reaches more than 42 cores, if according to past employing cable drum mode, except on main carriage, increasing the complicated cable roll device, also will dispose one the 42 above slip ring current collector of core, it costs an arm and a leg, and the fault point increases, increase the deadweight and the space of running trolley again, made the vehicle structure complexity.If adopted cable frame mode according to the past, though structure is simple, rely on cable from focusing on turnover cable frame in the process of hoisting, when fast rise or strong wind,, the deadlock of cable causes taking place the accident that cable is broken owing to can not entering frame smooth-goingly.These aspects are perplexing harbour user and crane supplier always.
Use the cable collection tube device of the tape guide among the present invention, just can address these problems, both simplified the structure, reduced cost again, its reliable operation.
