The inner sides of the mounting sleeves 3 are provided with equidistantly distributed positioning grooves 4. The outer sides of the mounting sleeves 3 are fixedly connected with three pairs of limit seats 5. The inner sides of the limit seats 5 are fixedly connected with sliding shafts 6. The sliding shafts 6 are fixedly connected to the mounting sleeves 3. The outer sides of the limit seats 5 are fixedly connected with rubber sheets 7. The outer sides of the mounting sleeves 3 are fixedly connected with three groups of buffer springs 8. The end of each group of buffer springs 8 away from the mounting sleeve 3 is fixedly connected with a protective plate 9. The upper and lower parts of the protective plate 9 are provided with sliding grooves 10. The protective plates 9 are slidably connected to the sliding shafts 6 through the sliding grooves 10. The outer sides of the protective plates 9 are fixedly connected with rubber plates 11. The upper and lower ends of the rubber plates 11 are provided with adjustment grooves 12. The inner sides of the protective plates 9 are fixedly connected with a pair of rubber strips 13.

[0025] The distance between the positioning rings 2 is equal to the distance between the positioning grooves 4. Each pair of mounting sleeves 3 is engaged with the positioning grooves 4 and the positioning rings 2. The mounting sleeves 3 are all semi-circular tubular structures. After the mounting sleeves 3 are fixed, they will not move in the radial direction of the steel pipe body 1; the limit seats 5 are all "L"-shaped seats, the sliding shafts 6 are all rectangular shafts, the shape of the rubber sheet 7 is consistent with the shape of the adjustment groove 12, and the limit seats 5 and the sliding shafts 6 can limit the protective plate 9; each group of buffer springs 8 has multiple, each group of buffer springs 8 is located between a pair of limit seats 5, and each group of buffer springs 8 is located between a pair of rubber strips 13. The buffer springs 8 and the protective plate 9 can further buffer; the protective plate 9 is all elastic metal plate, and the length of the protective plate 9, rubber plate 11, and rubber strip 13 is the same. The back side of each pair of rubber strips 13 is aligned with the side of the protective plate 9, and the rubber strip 13 can further improve the buffering effect.

[0026] Working process: Before use, multiple pairs of mounting sleeves 3 are fixed to the outside of the steel pipe body 1 by bolts. The mounting sleeves 3 are engaged with the positioning ring 2 on the outside of the steel pipe body 1 through the positioning groove 4. After the mounting sleeves 3 are fixed, they will not move in the radial direction of the steel pipe body 1. The device limits the protective plate 9 through the limit seat 5 and the sliding shaft 6. The buffer spring 8 is in a compressed state when there is no object colliding. The protective plate 9 is kept away from the mounting sleeve 3 by the elastic force of the buffer spring 8. At this time, the outside of the protective plate 9 is in contact with the limit seat 5, and the limit seat 5 is partially located in the adjustment groove 12 of the rubber plate 11. The outside of the limit seat 5 is provided with a rubber sheet 7, the outside of the protective plate 9 is provided with a rubber plate 11, and the protective plate 9 is provided with a rubber plate 9.

When an external object collides with the device, the object first contacts the rubber sheet 7 or rubber plate 11. The rubber sheet 7 and rubber plate 11 use their own elasticity for buffering. Then the buffer spring 8 is further compressed, and the protective plate 9 slides along the sliding shaft 6 through the sliding groove 10, which can further buffer. If the impact force of the object is strong, the rubber strip 13 contacts the mounting sleeve 3, which can further improve the buffering effect. The device has a multi-layer impact-resistant structure and has a good buffering effect. It can prevent the surface of the steel pipe body 1 from being damaged by collision with the object and extend the service life of the steel pipe body 1.
