Description
Technical field
The utility model belongs to the attached facility that helps, and specifically a kind ofly is convenient for changing the device that the transfer crane hoist rope is used.
Background technology
Use the transfer crane loading and unloading container, be to lift container spreader by four hoist ropes on the cylinder of dolly winch on the door frame to realize, promptly the head end of four steel ropes is fixed on the cylinder of dolly winch, have the changed course assembly pulley that hoists separately in the cooresponding car frame of pile warp now, and the pulley of installing on four angles of container spreader, its end returns on the vehicle frame that is fixed on dolly, and freight container lifts by crane by lockset and container lock stressed joint below the suspender.Handle lockset, can or unclamp freight container and suspender locking.Change the hand of rotation of dolly elevator cylinder, the freight container below the suspender can be mentioned or put down.
Because the handling labor of container wharf is very busy, steel rope frequently rises and falls and can produce fatigue.For guaranteeing the safety of handling labor, steel rope must regularly replace, and to avoid rope-broken accident.
Since four hoist ropes on the changed course assembly pulley that hoists around to very complicated, and the diameter of hoist rope reaches 26mm, long about 80 meters of every steel rope, weight is more than 200 kilograms, more change steel rope bothers very much.The existing more method of change steel rope is, earlier with four old steel ropes after the attachment point in the car frame is with the artificial unloading, the people stands in the car frame and with tiny hauling rope old steel rope is put into ground, to be placed on ground-surface new steel rope termination again and tie up to the hauling rope lower end, manually lift hauling rope, make the end head pass the changed course assembly pulley that hoists accordingly respectively, need the suspension rod of crane auxiliary sometimes.By hauling rope 4 hoist rope one ends are moved on the cylinder of dolly winch fixingly, the other end is fixed on the attachment point in the car frame, just finish the replacing of hoist rope.Usually changing steel cable probably needs 2-3 hour, leans on manpower up to draw with 4,5 people, and whole process work capacity is big, and the consumption time is long, labour intensity is big and dangerous, and the manpower and the equipment that take are many, have influenced normally carrying out of handling labor.
The utility model content
Technical problem to be solved in the utility model is, overcome prior art and change four hoist ropes of transfer crane, need many people also will cooperate accessory equipment just can finish, work capacity is big, the consumption time is long, working strength is high, the shortcoming that manpower that takies and equipment are many provides a kind of more changing device of wire rope of gantry crane.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the more changing device of described steel rope comprises the changed course assembly pulley that hoist rope walks around, the hauling rope that can tie up to the hoist rope termination; Be equipped with in the car frame of transfer crane and change the rope winch, the cylinder that changes the rope winch is arranged side by side and parallel with the hoist rope cylinder of dolly winch; One end of two hauling ropes is separately fixed at and changes rope winch cylinder two ends, and the other end of hauling rope is for can fall to ground-surface free end; In car frame, also be equipped with, when the hauling rope on will changing rope winch cylinder is guided ground into, a plurality of changed course pulleys that hauling rope needs the change of direction place to be provided with on by car frame.
The utility model also has following technical characterictic:
The support of described changed course pulley is, the labyrinth type support that is combined into by " U " shape plate and " L " shape plate;
Described labyrinth type support is supported with pulley in " U " shape plate " U " shape, " U " is one side the another side of being longer than " U " shape of shape plate is long limit; The vertical edge of " L " shape plate is perpendicular to " U " shape plate long limit suitable for reading, and its " L " pin is buckled on the long limit fixing downwards, the top that " U " shape plate is suitable for reading with fix after " L " shape plate between opening described hauling rope is passed through.In " U " shape bottom of " U " shape plate, be fixed with leg perpendicular to long limit, leg and the vertical edge of " L " shape frame constitute the supporting leg of labyrinth type support jointly.
When not using rope changer, two hauling ropes are to be wound on the cylinder that changes the rope winch.To change the cylinder reversing of rope winch when changing rope and pull out hauling rope, with wherein one by being installed in the described changed course pulley in the car frame, after arriving the attachment point of hoist rope to be replaced, be connected with the two ends of old hoist rope to be replaced, by changed course pulley and existing changed course assembly pulley old steel rope is hauled hauling rope under the effect of deadweight and arrive ground, finish the dismounting of old steel rope.And then new hoist rope two ends are connect with two hauling ropes respectively, start and change the rope winch and just changeing hauling rope is rolled, when an end of hoist rope is towed to fixed point in the car frame, removes with being connected and fixed of hauling rope and take root; When the other end of hoist rope drew to the hoist rope cylinder, same releasing was connected with hauling rope, is fixed on the hoist rope cylinder, has so just finished the erection work of hoist rope.
Advantage of the present utility model and good effect are, owing in the car frame of transfer crane, be equipped with and change the rope winch, changing to roll up on the rope winch cylinder has two can fall to ground-surface hauling rope, simultaneously, the guiding of passing through when hauling rope is turned to changed course pulley also is installed in the car frame, when two hauling rope terminations are connected to the two ends of hoist rope, start and change the rope winch, walk around the changed course pulley and the existing changed course assembly pulley of new installation respectively, old steel rope that can will pull down is put into ground and new steel rope is moved on the attachment point on the dolly.Use said apparatus not need to stand in stay cord in the car frame by the people, greatly reduce labour intensity, it is few to take human resources, safe and reliable; Do not need simultaneously other accessory equipments such as crane, change the time weak point that rope consumes.According to measuring and calculating, use said apparatus more change steel rope compared with prior art can improve work efficiency 2-3 doubly, and the time of being saved is put in the handling labor, and its benefit is considerable.
