Sliding type lifter slewing and anti-torsion device of pulley cars

The invention provides a sliding type lifter slewing and anti-torsion device of pulley cars. The sliding type lifter slewing and anti-torsion device of pulley cars comprises at least four lifting pulley sets, at least two sliding cars, at least two sliding guide mechanisms and at least two driving mechanisms, wherein the lifting pulley sets are respectively arranged in front of and behind the sliding cars; the sliding cars are arranged on corresponding steel rails through the sliding guide mechanisms; the driving mechanisms are respectively used for pushing the sliding cars to slide forwards and backwards on the corresponding steel rails. The lifter slewing and anti-torsion device provided by the invention is arranged on a running car, has the advantages of being compact in structure and convenient to demount, can directly and intuitively control the slewing action of lifters, can quickly respond to lifter systems required to rectify deviation, and can quickly rectify the torsional attitude of lifters, so that drivers can quickly and accurately make alignment, the success rate is high, and the loading and unloading efficiency at wharfs is improved.
