DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figure 1-4 As shown, a rust removal device for the inner wall of a steel cylinder comprises a base 1, a cylinder 2 is arranged on the top of the base 1, one end of the cylinder 2 passes through the top of the base 1 and is fixedly connected to a rack 3, and a fastening structure 5 is arranged at the bottom of the rack 3;
[0025] The fastening structure 5 includes two telescopic rods 6, which are respectively arranged on both sides of the bottom of the rack 3, one end of the two telescopic rods 6 is respectively connected to both sides of the top of the baffle 7, two springs 8 are respectively arranged between both sides of the top of the baffle 7 and both sides of the bottom of the rack 3, two pull bolts 9 are movably arranged on both sides of the bottom of the baffle 7, and one end of the two pull bolts 9 is fixedly provided with a triangular fastening plate 10.
[0026] Start the cylinder 2, so that the storage rack 3 slides down toward the inner bottom surface of the base 1. During the sliding process, the triangular fastening plate 10 contacts the bottle mouth of the steel cylinder. Under the action of pressure, the two triangular fastening plates 10 carry the two pull bolts 9 to slide on the inner side of the baffle 7 near the two ends of the baffle 7. When the baffle 7 is against the two sides of the bottle mouth, the spring 2 11 rebounds with the triangular fastening plates 10, so that the triangular fastening plates 10 are close to the two sides of the bottle mouth of the steel cylinder, and the operation of the cylinder 2 is stopped. At this time, the bottle mouth of the steel cylinder is restricted and fixed by the triangular fastening plates 10 and the baffle 7, and the rust removal component 4 can be used to remove rust from the inner wall of the steel cylinder.
[0027] In this embodiment, two springs 11 are respectively arranged between one side of the two triangular fastening plates 10 and the two sides of the bottom of the baffle 7 , and the two triangular fastening plates 10 are both slidably arranged on the inner side of the baffle 7 .
[0028] The second spring 11 provides elastic support to the triangular fastening plate 10 .
[0029] In this embodiment, the two springs 11 are respectively adapted to match the positions of the two pull bolts 9 , and the two springs 1 8 are respectively adapted to match the positions of the two telescopic rods 6 .
[0030] The spring 1 8 cooperates with the telescopic rod 6 so that the distance between the baffle 7 and the storage rack 3 is limited.
[0031] In this embodiment, a rust removal assembly 4 is disposed at the middle position of the bottom of the rack 3 , and two ends of the rack 3 are slidably disposed at two ends of the base 1 , so that the rack 3 and the base 1 are adaptively matched.
[0032] The rust removal component 4 can remove rust from the inside of the cylinder under the action of the cylinder 2 and the rack 3.
[0033] In this embodiment, auxiliary structures 12 are provided at both ends of the rack 3, and the auxiliary structures 12 include four concave plates 13, which are respectively provided at both ends of the rack 3, and sliding rods 14 are fixedly provided on the inner sides of the concave plates 13, and sliders 15 are slidably provided on the outsides of the four sliding rods 14, and four springs 16 are respectively provided between the tops of the four sliders 15 and the inner top surfaces of the inner sides of the four concave plates 13, and connecting arms 17 are rotatably provided at the front parts of the sliders 15, and the other ends of the four connecting arms 17 are respectively rotatably provided on both sides of the two arc-shaped plates 18.
[0034] When the storage rack 3 moves downward, the storage rack 3 moves downward synchronously with the concave plate 13. Under the action of the spring three 16, the slider 15 acts on the curved plate 18 through the connecting arm 17 to slide toward both sides of the cylinder until the curved plate 18 is close to the outside of the cylinder. When the curved plate 18 is close to the outside of the cylinder, the storage rack 3 continues to move downward, and the cylinder acts on the curved plate 18. The curved plate 18 makes the slider 15 slide vertically upward toward the direction of the cylinder 2 on the outside of the slide rod 14 with the spring three 16 through the connecting arm 17. During this process, the curved plate 18 is always close to the cylinder to fix the cylinder, and the guide rod 19 limits the curved plate 18 to prevent it from deflecting.
[0035] In this embodiment, the two arc plates 18 are symmetrically slidably arranged on the inner bottom surface of the base 1 through four guide rods 19, and one end of the four guide rods 19 passes through the two sides of the inner side of the base 1 near the bottom.
[0036] The guide rod 19 limits the moving direction of the arc plate 18 .
[0037] In this embodiment, the sliders 15 are all adaptable to the slide rods 14 , and the connecting arms 17 are all adaptable to the arc-shaped plates 18 .
[0038] The connecting arm 17 enables the storage rack 3 and the arc-shaped plate 18 to work in conjunction with each other.
[0039] It should be noted that the utility model is a rust removal device for the inner wall of a steel cylinder. When in use, it is placed at a site where it needs to work, so that it can reach the working operating conditions;
[0040] During the process, the cylinder 2 is started, so that the storage rack 3 slides down toward the inner bottom surface of the base 1. During the sliding process, the triangular fastening plate 10 contacts the bottle mouth of the steel cylinder. Under the action of pressure, the two triangular fastening plates 10 carry the two pull bolts 9 to slide on the inner side of the baffle 7 near the two ends of the baffle 7. When the baffle 7 is against the two sides of the bottle mouth, the spring 2 11 rebounds with the triangular fastening plate 10, so that the triangular fastening plate 10 is close to the two sides of the bottle mouth of the steel cylinder, and the cylinder 2 stops working. At this time, the bottle mouth of the steel cylinder is restricted and fixed by the triangular fastening plate 10 and the baffle 7, and the rust removal component 4 can be used to remove rust from the inner wall of the steel cylinder.
[0041] During the process, when the storage rack 3 moves downward, the storage rack 3 moves downward synchronously with the concave plate 13. Under the action of the spring three 16, the slider 15 acts on the curved plate 18 through the connecting arm 17 to slide toward both sides of the cylinder until the curved plate 18 is close to the outside of the cylinder. When the curved plate 18 is close to the outside of the cylinder, the storage rack 3 continues to move downward, and the cylinder acts on the curved plate 18. The curved plate 18 makes the slider 15 slide vertically upward toward the direction of the cylinder 2 on the outside of the slide rod 14 with the spring three 16 through the connecting arm 17. During this process, the curved plate 18 is always close to the cylinder, fixing the cylinder, and the guide rod 19 limits the curved plate 18 to prevent it from deflecting.
