Abstract
Description
Technical Field
[0001] The utility model relates to an anti-jamming device for a sector roller and belongs to the technical field of continuous casting sector equipment. Background Art
[0002] The fan-shaped section design of our large square billet continuous casting machine adopts a close-packed roller structure. During the production process, it is difficult to discharge the slag, which often accumulates around the rollers and bearing seats. Due to the high temperature around the billet, the seal of the roller will be burned quickly, affecting the sealing effect. There is a gap between the roller and the seal. During the production process, the slag is washed or rolled into the bearing, causing the bearing to rotate inflexibly and the roller to stop rotating, which in turn causes scratches or indentations on the billet, posing a great quality risk, so this situation must be improved. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide an anti-jamming device for a sector roller in view of the above-mentioned prior art, so as to avoid the roller being jammed due to the oxide slag entering the bearing and improve the quality of the casting.
[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: an anti-stuck device for a fan-shaped segment roller, comprising a roller, bearing seats are respectively arranged at both ends of the roller, the rollers are respectively fixed in the bearing seats through bearings, cover plates are respectively covered on the opening sides of the bearing seats, and skeleton seals are respectively arranged between one side of the bearing and the cover plate, and between the other side of the bearing and the bearing seat; a slag-proof cover plate is covered on the outer side of the cover plate; oil filling holes are respectively arranged on the top of the bearing seat, and the oil filling holes are connected with the inner cavity of the bearing seat; swivel joints are respectively arranged on the outer side of the cover plate, and a through central channel is arranged in the center of the roller, the swivel joints are respectively penetrated by the slag-proof cover plate and the cover plate and connected with both ends of the central channel, and metal hoses are respectively connected to the swivel joints.
[0005] The rotary joint is fixed on the slag-proof cover plate through a clamping plate.
[0006] The slag-proof cover plate is provided with a joint hole, and the joint hole matches the rotary joint.
[0007] The distance between the two end surfaces of the roller and the bearing seats on the corresponding sides is greater than 3 mm.
[0008] A dust ring is also provided between the bearing seat and the inner side surface of the bearing.
[0009] Compared with the prior art, the utility model has the advantages of: an anti-jamming device for a sector roller, two seals are respectively arranged on both sides of the bearing seat, which prevents oxide slag from entering the bearing, prevents the roller from getting stuck, and improves the quality of the casting.

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0015] like Figure 1 , 2 As shown in Figures 3 and 4, an anti-seizure device for a sector roller in this embodiment comprises a roller 9, bearing seats 6 are respectively provided at both ends of the roller 9, and the bearing seats 6 on the corresponding sides are respectively penetrated at both ends of the roller 9, and the bearing seats 6 and the roller 9 are respectively fixedly connected through bearings 5, so that the roller 9 can rotate in the bearing seats 6. Cover plates 3 are respectively covered on the opening sides of the bearing seats 6, and skeleton seals 4 are respectively provided between one side of the bearing 5 and the cover plate 3, and between the other side of the bearing 5 and the bearing seat 6, so as to seal both sides of the bearing 6. Oil filling holes 2 are respectively provided on the top of the bearing seat 6, and the oil filling holes 2 are connected with the inner cavity of the bearing seat 6. Rotary joints 10 are respectively provided on the outer side of the cover plates 3, and a through central channel is provided in the center of the roller 9. The rotary joints 10 penetrate the cover plates 3 and are connected with both ends of the central channel, and metal hoses 7 are respectively connected to the rotary joints 10. Grease flows into the outer ring of the bearing through the oil filling hole and then enters the inside of the bearing, replenishing the bearing with grease, and at the same time, foreign matter in the bearing can be discharged. The outer side of the cover plate 3 is covered with a slag-proof cover plate 11, and a joint hole is provided on the slag-proof cover plate 11, and the joint hole matches the rotary joint, and the rotary joint is penetrated with the joint hole, and the rotary joint is fixed to the slag-proof cover plate through the clamping plate 8. The slag-proof cover plate can fix the rotary joint to prevent the rotary joint from rotating, which has a good sealing effect on the one hand, preventing the oxide slag from entering the cover plate through the joint hole, and on the other hand, preventing the metal hose from being twisted off.
[0016] The above-mentioned bearing is a deep groove ball bearing.
[0017] The roller is a drum-shaped structural member, and the distance between the two end surfaces of the roller and the bearing seat on the corresponding side is greater than 3mm.
[0018] A dust ring 1 is also provided between the bearing seat and the inner side of the bearing to effectively prevent the oxide slag inside the bearing seat from entering the bearing seat.
[0019] Two seals are arranged on both sides of the bearing seat of the present application, which prevents oxide slag from entering the bearing, prevents the roller from getting stuck, and improves the quality of the casting.
[0020] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
