Hydraulic jacking hatch cover crane

Abstract

The invention discloses a hydraulic jacking hatch cover crane, and relates to the technical field of hoisting equipment. The hydraulic jacking hatch cover crane comprises two supporting bases, a lifting appliance, a hatch cover and a guide rail; the upper parts of the two supporting bases are fixedly connected with hydraulic oil cylinders through bolts; the two sides of the lifting appliance are fixedly connected with connecting arms; the two connecting arms are fixedly connected to the upper ends of the hydraulic oil cylinders; and the two sides of the lower surface of the lifting appliance are each fixedly connected with two lifting hooks. According to the hydraulic jacking hatch cover crane, the hydraulic oil cylinders, the connecting arms and the lifting appliance are cooperatively arranged, so that the dangerous situation that a rope is corroded and broken in the using process of a traditional hatch cover crane is avoided, effective post-event reaction time is provided, workers are able to remind each other to pay attention on avoidance, and convenience is brought to temporary shutdown maintenance; and limiting seats, fixing plates and rollers are matched, so that the liftingappliance, the lifting hooks and the hatch cover are prevented from shaking greatly, and the stability and safety of the hatch cover during hoisting are improved.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a hydraulic jacking hatch cover crane. Background technique [0002] The marine portal hatch crane is a special lifting device for lifting the upper hatch cover of the ship. The lifting device is installed on the ship deck, and the track is laid on both sides of the ship deck. The hatch cover crane runs along the track, and the working surface covers the entire ship. On the upper surface of the deck, this equipment can not only be used to lift the hatch cover, but also can lift other materials. The existing ship hatch covers are divided into lift-off type, side-open type, folding type, etc. At present, the common ship hatch covers are lift-off The control principle of the lift-off hatch cover is simple. It is directly lifted by the lifting equipment on the ship with the help of wire ropes, snap rings, shackles and eye plates. The single-piece hatch cover of this kind o...
