[0042] Referring to Figures 1-2 , combined with Figures 3-5 , the steel wire rope protection device of the shunting winch in the present application is mainly used for limiting and pressing the steel wire rope 50 in the iron ox shunting winch system, mainly relates to the pressing and covering of the steel wire rope 50 at the main machine dispatching winch 10 part, and the limiting and pressing between the main machine dispatching winch 10 and the deflection pulley 30, or between the deflection pulleys 30.

[0043] In the pressing process and the limiting and pressing process, through the rotation of the pressing roller and the stretching of the steel wire rope 50, the stable movement of the steel wire rope 50 can be ensured.

[0044] The steel wire rope protection device of the shunting winch provided by the utility model, comprising: a first steel wire rope pressing assembly 1 and a second steel wire rope pressing assembly 2;

[0045] The first steel wire rope pressing assembly 1 is connected on the speed reducer box 20 of the main machine dispatching winch 10, and comprises a first pressing roller 11 for limiting and pressing the steel wire rope 50 on the friction wheel 40, and a plurality of pressing roller ring grooves 111 are arranged on the first pressing roller 11;

[0046] The second steel wire rope pressing assembly 2 is arranged between the main machine dispatching winch 10 and the deflection pulley 30, and comprises a second pressing roller 21 for pressing the suspended steel wire rope 50.

[0047] Through the first steel wire rope pressing assembly 1 and the second steel wire rope pressing assembly 2, the stable stretching movement of the steel wire rope 50 on the friction wheel 40 and the stable stretching movement of the steel wire rope 50 in the turning process can be maintained respectively, and the risk of derailment, disorder and instability of the steel wire rope 50 can be avoided.

[0048] In one specific embodiment, from the perspective of the first steel wire rope pressing assembly 1, the first pressing roller 11 is connected to the reducer box 20 through an L-shaped support steel plate 12, which includes a bent top plate 121 and a side plate 122 that is fixed to the reducer box 20 by bolts.

[0049] The L-shaped support steel plate 12 constitutes the mounting base of the first pressing roller 11 and also constitutes the mounting connection between the first pressing roller 11 and the reducer box 20.

[0050] Further, the bottom wall of the top plate 121 is connected with a vertically arranged hanging plate 13, which includes two oppositely arranged plates. The first pressing roller 11 is rotatably connected between the hanging plates 13 through a first penetrating shaft 14, which allows the first pressing roller 11 to rotate on the first penetrating shaft 14, ensuring the smoothness of the steel wire rope 50 stretching movement. The two ends of the first penetrating shaft 14 are respectively connected to the hanging plates 13, which can fix the first penetrating shaft 14 and further fix the mounting position of the first pressing roller 11.

[0051] Through the arrangement of the first pressing roller 11, the steel wire rope 50 can be pressed between the friction wheel 40 and the first pressing roller 11, effectively regulating the position of the steel wire rope 50 and preventing the phenomenon of derailment and disordered rope of the steel wire rope 50 on the friction wheel 40.

[0052] The first pressing roller 11 includes a solid pressing roller. Preferably, the first pressing roller 11 is a φ133 solid steel roller. The cast steel part has high hardness, plasticity and toughness, good weldability, low cost and good wear resistance.

[0053] The two side end faces of the first pressing roller 11 are respectively connected with pressing roller end covers 112, which further prevent the steel wire rope 50 from escaping from the pressing constraint between the first pressing roller 11 and the friction wheel 40.

[0054] The profile size of the pressing roller end cover 112 is larger than that of the first pressing roller 11, and the rim of the pressing roller end cover 112 is relatively protruding from the rim of the first pressing roller 11. The protruding rim can form an effective shielding ring plate to effectively prevent the steel wire rope 50 from sliding out of the first pressing roller 11 and reduce the wear of the steel wire rope 50.

[0055] The pressing roller ring grooves 111 on the first pressing roller 11 are uniformly arranged on the roller surface of the first pressing roller 11. The friction wheel 40 is provided with a friction wheel rope groove 41 for accommodating the steel wire rope 50. The positions of the pressing roller ring grooves 111 and the friction wheel rope groove 41 are opposite and centrally opposite.

[0056] Through the setting mode, the movement range of the steel wire rope 50 can be limited, the steel wire rope 50 is accurately overlaid between the friction wheel rope groove 41 and the press roller ring groove 111, and it is ensured that each steel wire rope 50 moves in the friction wheel rope groove 41 of the friction wheel 40 without skipping rope and disordering rope.

[0057] In another specific embodiment, from the perspective of the second steel wire rope pressing assembly 2, the second steel wire rope pressing assembly 2 comprises a press roller support 22, and the second press roller 21 is installed on the press roller support 22. The second press roller 21 in the embodiment is mainly used for pressing the suspended steel wire rope 50 downward. Specifically, the second press roller 21 and the necessary counterweight structure are pressed on the suspended steel wire rope 50 under the action of gravity, and the movement of the steel wire rope 50 is realized under the condition that the second press roller 21 can freely rotate, accompanied by the downward friction force between the second press roller 21 and the steel wire rope 50.

[0058] Therefore, the press roller support 22 comprises an outer support frame 23 and an inner support frame 24. The outer support frame 23 is fixedly installed on the ground, and the inner support frame 24 is slidably installed on the outer support frame 23. The second press roller 21 is installed at the bottom of the inner support frame 24 and can linearly and tangentially contact the steel wire rope 50.

[0059] In a specific installation, the inner support frame 24, the second press roller 21 and the necessary configuration are independent of the overall structure of the outer support frame 23, and can slide up and down on the outer support frame 23 following the fluctuation of the steel wire rope 50 during movement.

[0060] The second steel wire rope pressing assembly 2 can ensure that the steel wire rope 50 has a reduced fluctuation amplitude before turning, and more stably realizes turning, so that the traction system operation is stable and safe.

[0061] From the specific structural composition, the outer support frame 23 comprises outer support groove steels 231 with opposite openings and a support bottom plate 232 connected at the bottom of the outer support groove steels 231. The support bottom plate 232 is fixed to the ground, so as to fix the outer support frame 23.

[0062] The inner support frame 24 is slidably installed between the outer support groove steels 231. Specifically, the inner support frame 24 is installed between the opposite grooves and can slide up and down, which facilitates plug-in installation on the outer support frame 23.

[0063] In order to prevent the steel wire rope 50 with a large fluctuation amplitude from ejecting and flinging the inner support frame 24 out in an extreme state, a limiting cover plate 233 is detachably connected to the top of the outer support frame 23. The limiting cover plate 233 is connected between the outer support groove steels 231, the outer support groove steels 231 are closed, the limiting protection of the inner support frame 24 is realized, and the safety of operation is ensured.

[0064] When connected, the top outer side of the two outer support channel steels 231 can be connected with the flaps 234, and the flaps 234 and the corresponding parts of the limiting cover plates 233 are provided with through holes, and the limiting cover plates 233 are fixed and installed in the form of bolt-nut penetration fixation.

[0065] Further, the inner support frame 24 includes open opposite inner support channel steels 241 and a cross beam channel steel 242 connected between the inner support channel steels 241, and the inner support channel steels 241 and the cross beam channel steel 242 are connected as an H-shaped inner support frame 24.

[0066] Specifically, the notches of the inner support channel steels 241 face the groove walls of the outer support channel steels 231, the size of the inner support channel steels 241 is smaller than the size of the outer support channel steels 231, and the outer support channel steels 231 and the inner support channel steels 241 are clearance-fitted, which can ensure the sliding of the inner support frame 24 in the outer support channel steels 231.

[0067] The notches of the cross beam channel steels 242 on the inner support frame 24 are upwardly arranged, and the counterweights 25 are movably installed in the notches of the cross beam channel steels 242, constituting the necessary counterweight structure as described above, which can ensure stable and reliable pressing down.

[0068] The second compression roller 21 is rotatably installed below the cross beam channel steel 242 through a second penetration shaft 26, which can be tangent to the steel wire rope 50. At the same time, in order to facilitate the installation and replacement of the counterweight 25 and the second compression roller 21, based on the notches of the inner support channel steels 241 facing the groove walls of the outer support channel steels 231, a slide 27 is formed on the middle groove wall of the inner support channel steels 241, and the slide 27 specifically includes slides 27 distributed upward and downward, and the thickness of the cross beam channel steel 242 plus the radius of the largest size second compression roller 21 is the middle separation area.

[0069] The two ends of the second penetration shaft 26 are clamped in the slide 27 from bottom to top, and the counterweight 25 is clamped in the slide 27 from top to bottom and seated on the notches of the cross beam channel steel 242. Through this arrangement, the installation position of the counterweight 25 and the second compression roller 21 can be regulated to ensure stability and reliability, and disassembly and replacement can be facilitated.

[0070] The clamping of the second penetration shaft 26 in the slide 27 can make the second compression roller 21 freely roll in combination with the pressing down friction of the second compression roller 21 and the steel wire rope 50, avoiding the static second compression roller 21 causing sliding obstacles to the movement of the steel wire rope 50.

[0071] The counterweight 25, the inner support frame 24 and the second compression roller 21 are pressed above the suspended steel wire rope 50, an effective pressing relationship can be realized, and can slide up and down freely under the fluctuation of the steel wire rope 50.

[0072] Participate Figure 6 The utility model further provides an iron bull shunting winch system comprising the above-mentioned shunting winch steel wire rope protection device, which can ensure the stability of the movement of the steel wire rope to the maximum extent.
