Abstract
The invention discloses a device for exchanging a wire rope of a gantry crane, which aims to overcome the defects that people and auxiliary equipment are needed, the workload is high, the consumed time is long, the working intensity is high, and the occupied resources are wide for exchanging a hoisting wire rope at present. The device comprises a redirection pulley block and hauling ropes. A rope exchanging winch is arranged on a frame of a crane trolley; one end of each of two hauling ropes is fixed at two ends of a roller of the rope exchanging winch respectively, and the other end is a free end; and a plurality of redirection pulleys for changing the walking direction of the hauling ropes are also arranged on the trolley frame. Because the two hauling ropes on the roller of the rope exchanging winch are wound around the redirection pulleys or the redirection pulley block, the ends of the hauling ropes can be connected to two ends of the hoisting wire rope on the ground respectively; and the rope exchanging winch is started, the hauling ropes haul the two ends of the hoisting wire rope to fix the two ends at respective fixing points on the trolley without manual work or other auxiliary equipment. Therefore, the labor intensity is reduced, the time is saved, and the working efficiency can be improved by 2 to 3 times by using the device.
Description
Technical field
The invention belongs to and attach the facility of helping, specifically a kind ofly be 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, separately existing hoist changed course assembly pulley and the pulley of installing on four angles of container spreader in the cooresponding car frame of pile warp; Its end returns on the vehicle frame that is fixed on dolly, and freight container leans on lockset and the container lock stressed joint lifting below the suspender.Handle lockset, can or unclamp freight container and suspender locking.Change the hand of rotation of dolly elevator cylinder, can the freight container below the suspender 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 complicated to very, 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, will be placed on ground-surface new steel rope termination again and tie up to the hauling rope lower end, and manual work lifts hauling rope; Make the end head pass the changed course assembly pulley that hoists accordingly respectively, need the suspension rod of crane auxiliary sometimes.Through hauling rope four 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 accomplish the replacing of hoist rope.Usually changing steel cable probably needs 2-3 hour, up draws by manpower 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.
Summary of the invention
Technical matters to be solved by this invention is; Overcome prior art and change four hoist ropes of transfer crane; Need many people also will cooperate accessory equipment to accomplish, work capacity is big, and 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 present invention adopts following technical proposals to realize: the more changing device of said 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; In the car frame of transfer crane, be equipped with 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 through car frame.
The present invention also has following technical characterictic:
The support of said changed course pulley is, the labyrinth type support that is combined into by " U " shape plate and " L " shape plate;
Said 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 said 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 through being installed in the said 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, through changed course pulley and existing changed course assembly pulley old steel rope hauled hauling rope under the effect of deadweight and arrive ground, accomplish 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 the fixed point in the car frame, removes and take root with being connected fixedly of hauling rope; 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 accomplished the erection work of hoist rope.
Advantage of the present invention 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 also is installed in the car frame uses the changed course pulley; 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; The 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 need not 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.
