For example, when the intermediate portion of the roll body unit 1 is worn seriously, only the intermediate portion of the roll body unit 1 is replaced, and the roll body unit 1 near the end fence 2 is worn less, so that normal use can be secured, and therefore the roll body unit 1 near the end fence 2 may not be replaced.
Method for changing the capacity of the reel by changing the number of reel body units:
when the change of the outer diameter and length of the steel rope to be wound is large, the end baffles 2 can be moved along the circumferential direction of the central shaft 3 to increase the distance between the two end baffles 2, the number of the reel body units 1 is added, and the steel rope winding capacity of the reel is increased.
The method for changing the winding radius by changing the winding drum body unit with different outer diameters comprises the following steps:
the winding outer diameter of the winding drum unit 1 can be changed by replacing the winding drum unit 1 of the outer circular arc plate 13 with different outer diameters under the condition of not replacing a rotary power part, thereby changing the winding arm of force. Since the rotary power part 5 is not changed, the winding moment is changed under the condition that the side winding moment arm is changed, so that the tension generated by the steel rope wound by the winding drum can be changed. The output torque of the rotary power member 5 is constant, and the tensile force generated by the reel winding wire rope increases when the outer diameter of the replacement reel body unit 1 decreases, and the tensile force generated by the reel winding wire rope decreases when the outer diameter of the replacement reel body unit 1 increases.
