Description
Technical Field
The utility model relates to the technical field of crane hoisting mechanism steel wire rope replacement equipment, in particular to a crane steel wire rope collecting device.
Background
The replacement operation of the steel wire rope of the crane lifting mechanism is a conventional maintenance operation project at present, and no safe, effective and convenient operation method exists before the old steel wire rope is coiled in the replacement process of the steel wire rope of the crane. The wire rope replacement maintenance operation is long in time consumption and also needs to be put into a large amount of manpower. The maintainer directly coils by hand in the process of coiling the old steel wire rope during the replacement operation of the crown block steel wire rope, and basically coils continuously for about 1 hour, and because the steel wire rope is hard and heavy, the labor intensity of the operator is increased in the process of coiling the old steel wire rope, and the operator frequently exposes the lower part of the crown block winding drum and simultaneously increases the safety risk of the operator.
At present, three crown block steel wire rope replacement methods are most widely used:
method 1: the new wire rope reel is vertically hoisted by using an electric hoist or a crown block auxiliary hook, then the wire rope head on the new wire rope reel is welded with the old wire rope head cut off in the crown block lifting hook, the new wire rope is brought into the lifting hook movable pulley through the operation of the crown block lifting reel, the new wire rope is wound on the winding reel after the fixed pulley is inserted, then the old wire rope is manually coiled on the ground, and then the new wire rope is fixed after being cut off, and the new wire rope is replaced.
Method 2: when the crown block is replaced by the steel wire rope, the novel steel wire rope reel is turned over by a forklift truck, the steel wire rope reel is horizontally placed on the ground, 1 long steel pipe is used for penetrating into the steel wire rope reel winding core, at the moment, two ends of the steel pipe are lifted up by forklift truck forks to be placed on two Y-shaped brackets with bases, then after the steel wire rope ends on the novel steel wire rope reel are welded with the old steel wire rope ends cut off in the crown block lifting hook, the novel steel wire rope is brought into the lifting hook movable pulley through the operation of the crown block lifting drum, the novel rope is wound onto the winding drum after the fixed pulley is inserted, then the old rope is manually coiled on the ground, the novel rope is fixed after the old rope is cut off, and the novel steel wire rope is replaced.
Method 3: the wire rope reel is placed above the turntable by using the rotary turntable, then the wire rope head on the new wire rope reel is welded with the old wire rope head cut off in the overhead traveling crane lifting hook, the new wire rope is brought into the lifting hook movable pulley by the operation of the overhead traveling crane lifting drum, the new rope is wound on the winding drum after the fixed pulley is inserted, then the old rope is manually fallen to the ground to be coiled, and then the new rope is cut off to be fixed, and the replacement of the new wire rope is finished.
The three crown block steel wire rope replacement methods can be seen: in any replacement method, the old steel wire rope is coiled manually, and then the old steel wire rope is coiled after the new steel wire rope is fully coiled by the reel, so that the old steel wire rope is coiled continuously and continuously; the crane which uses one steel wire rope or two steel wire ropes is used, and at least two people are required to coil the old steel wire rope respectively, and as the new steel wire rope is welded with the old steel wire rope when being coiled, a part of bolts and a protecting device are required to be removed in the process of replacing the steel wire rope, the labor intensity is increased intangibly, and the safety risk of ground maintainers is increased; the method for replacing the steel wire rope by the three crown blocks has the labor input for maintenance of 7-8 persons, and the maintenance time is about 6-8 hours.
