The decelerating through motor reel that described decelerating through motor reel is the multilayer wirerope-winding.
Described decelerating through motor reel top is provided with from the electronic screw mandrel rope winding jib of motion tracking, describedly from the electronic screw mandrel rope winding jib of motion tracking, comprise screw mandrel, be arranged on the screw mandrel upper bracket, the two ends of described support are respectively arranged with direction detection device, and described screw mandrel one end is provided with reducing motor.
Also include transmission device and driver train, described driver train drives the lifting trolley motion by transmission device, described driver train is reducing motor, described transmission device is gear & rack structure, described gear is separately positioned on two tracks, tooth bar is arranged on lifting trolley, and reducing motor drives two gears on track to rotate simultaneously.
Principle of work of the present utility model is:
Hoisting crane is positioned at cabin, and on the track of frame, move, the lifting trolley of hoisting crane also moves on the main body crane span structure of hoisting crane, until the suspension hook on steel rope moves to, needs position, suspension hook now descends, hang up steel rope, the suspension hook that hoists, then jenny and dolly, to the needs position, the suspension hook that descends again, until goods lands or falls on ship, take off steel rope and get final product.
Advantage of the present utility model is:
1, the utility model is directly installed on the frame of wind-power engine room, rainproof, safe, easy to use.And can be arranged on for a long time on frame standby, available at any time.Can realize the oblique pull function, the parts in cabin directly can be hung on ship.
2, traditional wheel driving is that roller is pressed and the frictional force drives of generation, therefore friction force is little.The propulsive effort of rack-and-gear and friction force are irrelevant, lean on the size of motor and retarder to guarantee.Guarantee the oblique pull lifting operation with this.
3, a motor drives two side gears, guarantees being synchronized with the movement of two gears.
4, the utility model has realized the judgement to the steel rope position by the direction detection device that is arranged on the support both sides, simple in structure.
5, lifting motor deceleration drum mechanism built is arranged in the crane span structure end, with lifting trolley, separates, and greatly reduces from the rise size.
