[0002] In the process of electrolytic aluminum production, overhead crane winches are needed to transfer aluminum ladle or other materials. The wire rope of the winch is exposed in the electrolytic plant, and the dust in the workshop is easy to adhere to the surface of the wire rope. If it is not cleaned in time, it may cause wear and corrosion damage to the wire rope, reducing the service life of the wire rope.

[0003] When cleaning the wire rope of the existing winch, the staff must operate at close range and keep the winch in working state to clean the dust on the surface of the descending or ascending wire rope, which is unsafe and increases the labor intensity of the staff. Utility Model Content

[0029] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0030] The following is combined with Figure 1 To Attachment Figure 3 And specific embodiments describe the present invention in detail.

[0031] like Figures 1 to 3 As shown, the utility model provides a wire rope blowing device for an overhead crane winch, comprising a blowing pipe 1, which is placed close to the wire rope. A plurality of blowing ports 11 are provided on one side of the blowing pipe 1 close to the wire rope, and the plurality of blowing ports 11 are distributed along the axial direction of the blowing pipe 1.

[0032] The side of the blowing pipe 1 away from the wire rope is fixedly connected to an air inlet pipe 2, and the air inlet pipe 2 is connected to an air compressor (not shown in the figure). The gas generated by the air compressor enters the blowing pipe 1 through the air duct and is then discharged from the blowing port 11 through the blowing pipe 1.

[0033] The winch 3 is fixedly connected to the support rod 4, the blowing pipe 1 is connected to the support frame 5, and a connecting component 6 is provided between the support frame 5 and the support rod 4. The position of the blowing pipe 1 in the vertical direction is adjusted by the connecting component 6. The blowing pipe 1 is adjusted to a suitable position according to actual needs on site. The connecting component 6 connects the support frame 5 with the support rod 4.

[0034] When the winch 3 is started, the wire rope rises or falls, and the air blowing port 11 blows air toward the moving wire rope to blow off the dust on the surface of the wire rope and clean the dust on the surface of the wire rope. It is not necessary for the staff to clean the moving wire rope at a close distance, which has the effect of improving safety and reducing the labor intensity of the staff.

[0035] The connecting assembly 6 includes a first connecting rod 61 fixedly connected to the end of the support rod 4 away from the winch 3, and a second connecting rod 62 fixedly connected to the upper surface of the support frame 5. The lower surface of the first connecting rod 61 is provided with a connecting groove 611 inwardly, and the second connecting rod 62 is slidably plugged into the connecting groove 611.

[0036] The vertical side wall of the first connecting rod 61 is provided with a plug hole 612, and the plug hole 612 is connected to the connecting groove 611. The second connecting rod 62 is provided with a plurality of plug grooves 621 on one side close to the plug hole 612, and the plurality of plug grooves 621 are evenly distributed along the vertical direction. A plug rod 63 is plugged into the plug hole 612, and the second connecting rod 62 is moved in the vertical direction, and the second connecting rod 62 drives the blowing pipe 1 to move through the support frame 5, and the blowing pipe 1 is adjusted to a suitable position, and then the plug rod 63 is plugged into the corresponding plug groove 621, and the plug rod 63 connects and fixes the second connecting rod 62 and the first connecting rod 61.

[0037] The plug rod 63 is an iron rod, and a magnet 622 is provided at the bottom of the plug slot 621, and the magnet 622 is fixedly connected to the second connecting rod 62. When the plug rod 63 is plugged into the plug slot 621, the magnet 622 attracts and abuts the plug rod 63, and the magnet 622 increases the stability of the plugging of the plug rod 63 and the plug slot 621.

[0038] The first connecting rod 61 is fixedly connected to the fixing rod 7 on one side of which the plug hole 612 is provided. The fixing rod 7 is rotatably connected to the baffle plate 71, which can only rotate around the axis of the fixing rod 7. After the plug-in rod 63 is plugged into the plug-in slot 621, the baffle plate 71 is rotated to make the baffle plate 71 abut against the side of the plug-in rod 63 away from the second connecting rod 62. The baffle plate 71 restricts the plug-in rod 63, reduces the possibility of the plug-in rod 63 being separated from the plug-in slot 621, and further increases the stability of the plug-in rod 63 and the plug-in slot 621.

[0039] When the second connecting rod 62 is moved, the baffle 71 is rotated so that the baffle 71 no longer abuts against the plug-in rod 63, and the plug-in rod 63 is moved to the side away from the second connecting rod 62 to separate the plug-in rod 63 from the plug-in slot 621. The plug-in rod 63 releases the restriction on the second connecting rod 62, and the second connecting rod 62 can be moved.

[0040] The air inlet pipe 2 is connected to a solenoid valve 8, which is electrically connected to a motor that controls the opening and closing of the hoist 3. When the hoist 3 is started, the solenoid valve 8 opens the air inlet pipe 2, and the air outlet 11 can blow air toward the moving wire rope while the wire rope is moving. When the hoist 3 is closed, the solenoid valve 8 synchronously closes the air inlet pipe 2.

[0041] like Figure 1 to Figure 2 As shown, a rotating assembly 9 is provided between the support frame 5 and the blowing pipe 1, and the blowing pipe 1 is connected to the support frame 5 through the rotating assembly 9. The blowing angle of the blowing port 11 to the steel wire rope is adjusted according to the actual needs on site by the rotating assembly 9. After the blowing angle of the blowing port 11 to the steel wire rope is adjusted appropriately, the rotating assembly 9 fixes the blowing pipe 1.

[0042] The rotating assembly 9 includes a rotating rod 91 fixedly connected to both ends of the blowing pipe 1, and the supporting frame 5 is provided with a pair of reserved holes 51. The rotating rod 91 is arranged in a one-to-one correspondence with the reserved holes 51, and the rotating rod 91 is rotatably connected to the reserved holes 51. The supporting frame 5 is threadedly connected with a pair of fixing bolts 92, and the fixing bolts 92 are arranged in a one-to-one correspondence with the rotating rod 91, and the fixing bolts 92 abut against the rotating rod 91.

[0043] The blowing angle of the blowing port 11 to the wire rope can be adjusted by rotating the blowing pipe 1. After the adjustment is completed, the fixing bolt 92 is tightened, and the fixing bolt 92 is pressed against the rotating rod 91. The fixing bolt 92 fixes the rotating rod 91 and then fixes the blowing pipe 1. The fixing bolt 92 is loosened, and the fixing bolt 92 is separated from the rotating rod 91, and the blowing pipe 1 can be rotated.

[0044] The implementation principle of the wire rope blowing device for the overhead crane winch provided by the utility model is as follows: the second connecting rod 62 is moved to adjust the position of the blowing pipe 1 in the vertical direction. After the position of the blowing pipe 1 is completed, the plug-in rod 63 is plugged into the plug-in slot 621, and the baffle 71 is rotated to make the baffle 71 abut against the side of the plug-in rod 63 away from the second connecting rod 62. The blowing pipe 1 is rotated to adjust the blowing angle of the blowing port 11 to the wire rope. After the adjustment is completed, the fixing bolt 92 is tightened, and the fixing bolt 92 abuts the rotating rod 91. When the winch 3 is started, the blowing port 11 blows the wire rope to clean the dust on the surface of the moving wire rope.

[0045] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
