[0017] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figs. 1 to 3 The embodiments are described in detail below.

[0018] This embodiment provides an anti-slip device for the wheels of a winding trolley, as shown in the attached figure. Figs. 1-3 As shown, the system includes a frame 1 and an upper adjustment seat 2. A trolley wheel 13 is rotatably connected to the side of the frame 1, and the bottom of the trolley wheel 13 is rolledly connected to the top of the track 12. The upper adjustment seat 2 is fixedly connected to the side of the frame 1, and a tensioning bolt 3 that can be spirally raised and lowered is threaded through its upper surface. A tensioning block 4 is provided at the bottom of the tensioning bolt 3. A nut is threadedly connected to the outside of the tensioning bolt 3, and the nut abuts against the lower surface of the upper adjustment seat 2. There are at least two tensioning bolts 3. The tensioning block 4 is threadedly connected to the bottom of the tensioning bolt 3, and tension springs 5 ​​are hung on both sides of the bottom of the tensioning block 4. By rotating the tensioning bolt 3, the tensioning block 4 below moves upward, and the tensioning bolt 3 can be locked and fixed by the nut, thereby fixing the position of the tensioning block 4 and preventing the tensioning block 4 from moving downward under the tension of the tension spring 5. The upward movement of the tensioning block 4 can pull the tension spring 5, increasing its tension.

[0019] Tensioning block 4 has a tension spring 5 attached to its bottom. There are at least two tension springs 5, which are evenly spaced and attached to the bottom of tensioning block 4. A connecting block 6 is attached to the bottom of tension spring 5, and a pressure seat 7 is fixedly installed on both sides of the connecting block 6. The connecting block 6 is attached to the bottom of tension spring 5 and is positioned above track 12. The width of the connecting block 6 is slightly larger than the width of the top of track 12. The two pressure seats 7 are wrapped around the top of track 12 on both sides and can move laterally outside of it, which can ensure that the pressure seats 7 can move normally along the outside of track when the subframe 1 moves.

[0020] The bottom of the pressing seat 7 is fixedly connected with a pin shaft 8, and the end of the pin shaft 8 is fixedly installed with a bearing 9. The pin shaft 8 can connect the bearing 9 with the pressing seat 7 as a whole and can keep the outer ring of the bearing 9 normal rotation. When the bearing 9 has a larger normal pressure between the lower inclined surface of the track 12, the bearing 9 can still roll along the track 12, ensuring the normal movement of the vehicle body 1. The two pressing seats 7 are fixedly installed on the two sides of the connecting block 6 and symmetrically arranged with the vertical center line of the connecting block 6 as the symmetric axis. The track 12 is arranged between the bottoms of the two pressing seats 7, and the bearings 9 at the bottoms of the two pressing seats 7 are rollingly connected to the lower inclined surfaces on the two sides of the track 12. When the tension spring 5 is pulled to increase the tension, the connecting block 6 and the pressing seat 7 can drive the bearings 9 on the two sides to move upward, and the bearings 9 abut against the lower inclined surface of the track 12, so as to increase the friction between the bearings 9 and the lower inclined surface of the track 12. The device and the trolley wheel 13 are connected with the vehicle frame 1, so that the normal pressure generated between the bearings 9 and the lower inclined surface of the track 12 is transmitted to the trolley wheel 13, the normal pressure between the trolley wheel 13 and the track 12 is also increased, and the traction of the trolley wheel 13 when rolling is improved, thereby preventing the trolley wheel 13 from slipping. The number of bearings 9 is four, and the four bearings 9 are evenly divided into two groups. The two groups of bearings 9 are arranged on the two sides of the bottoms of the two pressing seats 7, and the bearings 9 at the bottoms of the two pressing seats 7 are symmetrically arranged on the two sides of the track 12.

[0021] The side surface of the vehicle frame 1 corresponding to the pressing seat 7 is fixedly connected with a lower fixing seat 10, and the side surface of the lower fixing seat 10 is fixedly connected with a clamping plate 11 which can vertically slide on the side surface of the pressing seat 7. The lower fixing seat 10 vertically corresponds to the upper adjusting seat 2, and the clamping plate 11 is fixedly connected to the side surface of the lower fixing seat 10 by bolts. The part of one of the pressing seats 7 close to the clamping plate 11 corresponds to the clamping groove, and the clamping plate 11 is vertically slidably connected in the clamping groove, which can limit the pressing seat 7 and ensure that the pressing seat 7 can vertically move after being pulled by the tension spring 5, so that the bearings 9 on the two sides of the bottom of the pressing seat 7 can fully abut against the lower inclined surface of the track 12, the pressure between each bearing 9 and the lower inclined surface of the track 12 is the same, and the trolley wheel 13 moves more stably on the track 12.

[0022] In summary, the anti-skid device for the trolley wheel for loading and unloading coils has the following use steps:

[0023] 1. The weight of the coil to be conveyed is adjusted by rotating the tensioning bolt 3 to adjust the tension of the tension spring 5. The tension spring 5 can increase the pressure between the bottom bearing 9 and the lower inclined surface of the track 12, thereby increasing the friction between the trolley wheel 13 and the track 12, ensuring that the trolley wheel 13 can travel stably on the track 12, and avoiding slipping.

[0024] 2、When the weight of the material roll to be transported is light, the tensioning bolt 3 is rotated to move the tensioning block 4 upward, thereby pulling the tension spring 5 to increase the pulling force of the tension spring 5, the tension spring 5 provides upward pulling force to the connecting block 6 and the pressing seat 7 at the bottom, thereby further increasing the pressing force between the bottom bearing 9 and the track 12, improving the traction force when the trolley wheel 13 rolls, and facilitating the smooth movement of the trolley on the track 12.

[0025] 3、Meanwhile, the number of the tension spring 5 can be increased or the tension spring 5 with greater pulling force can be selected to change the pressing force between the bearing 9 and the track 12 according to the situation, which can effectively avoid the slipping of the trolley wheel 13.

[0026] The above description is only for the purpose of illustrating the present application, and it should be understood that the present application is not limited to the above embodiments, and various modifications in accordance with the idea of the present application are within the scope of the present application.
