In the present invention, by the carrying roller 10 that can roll along the rotation direction of drum grooves is installed in drum grooves, has guaranteed that hauling rope 20 and new steel cable 40 can be free to slide in drum grooves, thereby under the condition of self not rotating at reel 1a, completed the replacing of steel cable.If carrying roller 10 is not set, in Renewal process, hauling rope 20 or new steel cable 40 are wrapped in the above locking phenomenon that just there will be of three circles in drum grooves, and, under the traction of actuating unit 30, hauling rope 20 or new steel cable 40 can not slide in drum grooves.
For the structure of carrying roller 10, requirement must arrange rotating shaft 12a, 12b at carrying roller body two ends, and the Main Function that rotating shaft is set is, in the process of avoiding carrying roller 10 to roll in drum grooves, job-hop phenomenon occurs, and for example carrying roller 10 is jumped in adjacent drum grooves.This be because, when hauling rope 20 and new steel cable 40 slide in the annular groove 11a of carrying roller 10, can produce friction force with carrying roller 10 and drive carrying roller 10 to roll according to predetermined ground track in drum grooves, described desired trajectory is consistent with the rotation direction of drum grooves, but the stressed rotation direction that may depart from drum grooves of carrying roller 10 in fact, now, if rotating shaft 12a, 12b are not set, carrying roller 10 is easy to depart from desired trajectory while rolling in drum grooves, cause the generation of job-hop phenomenon.
And for annular groove 11a, just as mentioned before, it mainly plays act as hauling rope 20 and new steel cable 40 provides the groove of slip and guarantee hauling rope 20 and sideslip not when new steel cable 40 slides in groove, thereby the dimensions of annular groove 11a is to carry out supporting design according to the specification of hauling rope 20 and new steel cable 40.In the above-described embodiments, be the mode that adopts " small steel rope drags large steel cable ", thereby adopt annular groove 11a structure as above.But the invention is not restricted to this, the present invention can also adopt steel cable that diameter is more than or equal to new steel cable 40 diameters as hauling rope 20, for example, can adopt " old steel cable drag new steel cable " mode, directly adopt old steel cable as hauling rope, now, annular groove 11a by the 4th camber line around the shaft the axis of 12a rotate a circle and the curved surface that forms, the radius of curvature of the 4th camber line is identical with the radius of hauling rope and new steel cable, and the 4th camber line is the arc that is not more than 1/2 circle; Again for example, when the diameter of hauling rope is greater than new steel cable 40, the structure when structure of annular groove 11a and the diameter of hauling rope are less than new steel cable 40 is similar, different, the radius of curvature R 2 of the second camber line radius of curvature R 3 identical with the radius of hauling rope 20 and the 3rd camber line is identical with the radius of new steel cable 40 in this case.But it should be noted that, the cable diameter of the heavy ox system of overturning is very large, and when the diameter of hauling rope is more than or equal to cable diameter, actuating unit 30 equipment of required employing are huge and cost is higher, therefore, preferably adopt the mode of " small steel rope drags large steel cable ".
In sum, the present invention by design can be by new steel cable automatic coiling the more changing device on reel, solved in prior art, need manually by steel cable slowly dish move the loaded down with trivial details operation process to reel, and then reduce labor intensity, shorten the repair time, save the cost of overhaul.
Although above by having described the present invention in conjunction with exemplary embodiment, it will be apparent to those skilled in the art that in the situation that do not depart from the spirit and scope that claim limits, can carry out various modifications and change to exemplary embodiment of the present invention.
