Description

Technical Field

[0001] This utility model relates to the field of silicon-coated vehicle guide wheels, and in particular to a durable ground wheel. Background Technology

[0002] The transportation of silicon bags for industrial silicon furnaces requires a 10t winch as the driving force. The winch's wire rope needs ground rollers for directional guidance. Each 33000KVA industrial silicon furnace uses 32 ground rollers. Due to the space limitation of the ground rollers, the bearing balls inside the ground rollers are prone to surface deformation and accelerated wear when subjected to radial forces outside their designed normal range, leading to the failure of the entire ground roller. The failure of a single ground roller can cause the silicon bag cart to deviate from its forward path, and it cannot be replaced in time, thus reducing the efficiency of silicon bag cart transportation.

[0003] Therefore, it is necessary to propose a durable ground wheel to solve the above problems. Utility Model Content

[0020] This utility model provides, for example Figures 1-3 A durable floor wheel is shown, comprising a floor wheel frame 4, a floor wheel axle 7, and floor wheels 8. The floor wheel frame 4 has upper and lower ends, and the two ends of the floor wheel axle 7 are respectively installed through the upper and lower ends of the floor wheel frame 4. The floor wheels 8 are movably sleeved on the outside of the floor wheel axle 7, and the floor wheels 8 are located between the upper and lower ends of the floor wheel frame 4. Both the upper and lower ends of the floor wheels 8 are provided with annular grooves, and bearing steel balls 12 are installed in the annular grooves of the floor wheels 8. 2 is in contact with the outer surface of the roller shaft 7. The upper end of the roller 8 is fixedly installed with the roller cover 6. The lower end of the roller 8 is movably installed with the roller ball base 5. The roller ball base 5 rests on the bearing ball 12 in the lower end annular groove of the roller 8. The roller ball base 5 is movably installed with the roller frame 4. The roller shaft 7 passes through the roller ball base 5 and the roller cover 6, and the roller shaft 7 and the roller ball base 5 are movably engaged.

[0021] Furthermore, two slots are provided near the top of the ground roller shaft 7. A shaft head locking piece 1 is installed in the slots of the ground roller shaft 7. The shaft head locking piece 1 is threaded with multiple screws 11. The shaft head locking piece 1 is fixedly connected to the ground roller frame 4 by the screws 11.

[0022] Furthermore, screw 213 is threaded onto the roller cover 6, and the roller cover 6 and the roller 8 are fixedly connected by screw 213.

[0023] Furthermore, four fixing screws 9 are threaded on the ground roller frame 4, and the fixing screws 9 are evenly distributed on the ground roller frame 4. A flat spring washer 10 is installed between the ground roller frame 4 and the fixing screws 9. A ground roller fixing base plate 3 is provided at the bottom of the ground roller frame 4, and the ground roller fixing base plate 3 is fixedly connected to the ground roller frame 4 by fixing screws 9.

[0026] In this embodiment of the utility model, when the silicon wafer is being transported, the ground roller 8 becomes unusable due to damage. At this time, screw 11 is removed, the ground roller shaft 7 is taken out from the ground roller frame 4, the ground roller 8 is then removed, a new ground roller 8 is installed, and the ground roller shaft 7 is inserted. Screw 11 is used to fix and limit the ground roller shaft 7 on the ground roller frame 4 through the shaft head locking piece 1. When it is necessary to replace the bearing steel ball 12, the ground roller cover 6 and the ground roller steel ball base 5 are opened on the removed ground roller 8. The appropriate bearing steel ball 12 is selected according to the actual needs. The bearing steel ball 12 is placed in the annular grooves at the upper and lower ends of the ground roller 8.

Then, the ground roller 8 is placed on the ground roller frame 4, the ground roller shaft 7 is inserted, and the ground roller shaft 7 is limited and fixed by the shaft head locking piece 1.

[0027] The working principle of this utility model is as follows: During the transportation of silicon wafers by the hoist wire rope, the hoist wire rope contacts the ground roller 8. The ground roller 8 rotates around the ground roller shaft 7 under the friction force, thereby guiding the wire rope and guiding the silicon wafer truck to move. The bearing steel balls 12 in the upper and lower annular grooves convert sliding friction into rolling friction and disperse radial force, reducing wear. When the ground roller 8 or the bearing steel balls 12 are damaged, the screw 11 is removed to unlock the shaft head locking piece 1, and the ground roller shaft 7 and ground roller 8 can be taken out for replacement. After replacement, they are reinstalled and fixed, thereby ensuring the continuous and stable operation of the silicon wafer truck transportation.
