The shunting winch is commonly called as a winch, is a driving device for dragging carriages such as train carriages to walk, is mainly suitable for a driving system for carrying and walking the carriages in a limited area in a production field, and is different from long-distance transportation of a train locomotive.
The shunting winch system mainly comprises a shunting winch, a rope guide wheel, a rope pressing wheel, a balance weight, a supporting roller, a matched steel wire rope and the like. The working principle of the shunting winch system is as follows: the steel ring is hung on the railway carriage fixing device through a plurality of connecting cable rings and drives the steel wire rope to bypass guide rope wheels at different positions so as to draw the slag car to run in the front and back directions, thereby respectively realizing the conversion of loading and unloading positions of an empty car body and a full car body. Until all the cars are filled with material, the shunting winch system is replaced by the rail vehicle, and the cars are hauled away.
At present, in the process of replacing a steel wire rope of a shunting winch, an old steel wire rope is replaced by a new steel wire rope, and two methods are mainly adopted in the prior art. One is that the steel wire rope is driven by a train locomotive, which needs to contact with the railway transportation department, and the train locomotive is used for driving a new steel wire rope to run along a straight line for a long distance. However, the time consumption is long when the transportation department is contacted, the time consumption for replacing the steel wire rope during the traction of the train locomotive is influenced by the short material loading and unloading interval time, the train wagon is not paired timely if the time control is improper during the traction process of the train locomotive, and particularly under the condition that the steel wire rope is suddenly broken, the train locomotive, the material carriage and the loader are all mixed in the cross operation, the efficiency is extremely low, and the production is influenced.
The other type is that a loader is adopted to drive a steel wire rope, the loader runs along a train track, signal lines beside the train track are easily damaged, and material loading, unloading and outward transportation are influenced. Conventionally, a shunting winch wire rope has a large self-weight and a large space for replacement, so that maintenance work is difficult.
Fig. 1 schematically illustrates a prior art system 10 for replacing a shunting winch cable as described above.
Referring to fig. 1, the replacing system 10 includes a shunting winch 20, a guide sheave assembly 30, a pressing sheave 40, a wire rope 50, and the like. The shunting winch 20 includes a traction machine 21, a tension weight device 22, a traction steel ring 23, a winch-used pressing sheave assembly 24, a connecting rope 25, and the like, wherein the traction steel ring 23 is disposed between the traction machine 21 and the tension weight device 22 to connect the traction machine 21 to the tension weight device 22 through the traction steel ring 23 and the connecting rope 25. The traction machine 21 comprises four rope pulleys on either side of the machine, two of which are located on one side of the machine 21 and two on the opposite side of the machine 21. The rope guide wheel assembly 30 includes a first end rope guide wheel 31 at a and a second end rope guide wheel 32 at B, and other intermediate rope guide wheels between a and B, wherein the first end rope guide wheel 31 and the second end rope guide wheel 32 are rope guide wheels located farthest from the shunting winch 20 on both sides of the shunting winch 20, respectively, and the first end rope guide wheel 31 and the second end rope guide wheel 32 are located on a straight line. The wire rope 50 is passed around the pressing sheave 40, the first intermediate guide sheave 33, the first end guide sheave 31, the second end guide sheave 32, the second intermediate guide sheave 34, and the third intermediate guide sheave 35 in this order counterclockwise from the traction machine 21, and is wound back to the traction machine 21 again, and then the wire rope 50 is passed around the four sheaves of the traction machine 21 in this order, thereby forming a closed loop.
The exchange system 10 is disposed between the vehicle track 70 and the roadway 80.
As shown in fig. 1, when the shunting winch 20 pulls the wire rope 50 to perform clockwise rotation, the train car 60 located on the vehicle rail 70 travels to the right in fig. 1; and when the shunting winch 20 pulls the wire rope 50 to perform counterclockwise rotation, the train car 60 located on the vehicle rail 70 travels leftward in fig. 1.
Accordingly, there is a need in the art for an improved replacement system for a shunting winch cable and an improved replacement method for a shunting winch cable that eliminates or at least alleviates some or all of the above-mentioned deficiencies in the prior art.

The above-mentioned "proper rope length" means that the first section of the new rope remains a length convenient for guiding at the second end deflector sheave 320, outside the joint where it is connected with the remaining portion of the old rope. The above "suitable rope length" may be, for example, 3 meters or more.
The "suitable distance" mentioned above refers to a distance that is less than the distance between the first end deflector sheave 310 and the traction machine 210, which facilitates connecting together the first and second ends of the first section of new rope.
In one embodiment, in step S24, after the second section of the new steel wire rope with the second suitable length is cut, the two ends of the second section of the new steel wire rope are respectively passed through the traction steel ring 230, fixed by knotting with the jaws, and then moved away from the moving device 800.
