Description
Technical Field
The invention relates to the technical field of bridge cranes in the metallurgical industry, in particular to a device for measuring the length of a steel wire rope of a bridge crane.
Background
In a large-tonnage bridge crane in the metallurgical industry, 4 steel wire ropes 12 are generally used for main lifting, and a reel winds the steel wire ropes 12 to enable a lifting hook to move up and down to extract heavy objects. Two steel wire ropes 12 are fixedly wound on one winding drum, the rope heads of the two steel wire ropes 12 are respectively fixed on two sides of the winding drum, a heavy lantern ring 13 is directly installed on the tail of the steel wire rope 12 by a manufacturer in a stamping mode before the steel wire rope 12 leaves a factory, and the heavy lantern ring 13 at the tail of the steel wire rope 12 is fixedly connected to the hook balancer 4 through a pin shaft, as shown in fig. 4a, 4b and 8. One winding drum, two steel wire ropes 12 and one balancer 4 form a group. And the main hoisting is two drums 4, two steel wire ropes 12 and two balancers 4. If the steel wire ropes 12 need to be replaced, 4 steel wire ropes 12 need to be replaced at the same time, so that the safety is ensured. Because the new steel wire rope 12 is from a manufacturer to a steel mill, one steel wire rope 12 is a rope coil 7 and is a package, the length of each steel wire rope 12 cannot be completely unified, and the error is about 1 meter. Meanwhile, a heavy lantern ring 13 at the tail end of the steel wire rope 12 is pressed on the tail end of the steel wire rope 12 in a punching mode and cannot be adjusted on the balancer 4. If the lengths of the steel wire ropes 12 are different, the balancer 4 on the hook fails, that is, the balancer 4 fails, that is, only one steel wire rope 12 on one side of the hook is stressed, and two steel wire ropes 12 are stressed, as shown in fig. 4b, the balancer 4 which is obliquely failed is shown in fig. 4a, and is the normal balancer 4. The balancer 4 can be checked to be out of work only after the steel wire rope 12 is completely replaced and the main coil is lifted to the state that the hook completely leaves the ground, if the main coil is out of work, the hook needs to be placed on the ground, the residual steel wire rope 12 wound on the winding drum is wound out and is placed on the ground, the clamping plate 9 for fixing the steel wire rope 12 on the winding drum is loosened, as shown in fig. 6, the tail steel wire rope 12 on the winding drum is lowered and pulled up to be lengthened or shortened to adjust the balance degree of the balancer 4 on the hook, and the rope is adjusted.
At present, because the lengths of 4 main winding steel wire ropes 12 are different, the length judgment is completely carried out by human vision, the accuracy cannot be completely achieved, the balancer 4 on a main winding hook is easy to fail, the lengths of the 4 steel wire ropes 12 must be readjusted to achieve the purpose of balancing stress of the 4 steel wire ropes 12, and the balancer 4 needs to be balanced by newly adjusting the lengths of the steel wire ropes 12 within about 120min, so that time and labor are wasted.
In conclusion, how to effectively solve the problem that the length of the steel wire rope can only be estimated and adjusted by manual vision in large scale, which is not completely accurate, is time-saving and labor-saving, and the like, is a problem that the technicians in the field need to solve at present.
