[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a shot blasting cleaning device for the inner wall of a steel pipe for idler rollers, which can automatically collect steel shot from the inner wall of the steel pipe when the sandblasting machine is retracted. It includes a collection component, including six collection frames 10. Each of the six collection frames 10 is fixedly connected to a collection frame 11 on one side close to each other. A sandblasting machine 12 for shot blasting cleaning is provided on the upper side of the collection frame 11. An adjustment component 13 is provided between the collection frame 11 and the sandblasting machine 12. A drive component 14 is provided between the adjustment component 13 and the collection frame 11. A covering component 15 is provided on the inner wall of the collection frame 11. A pushing component is also provided. An anti-accumulation component 20 is provided between the drive component 14 and the collection frame 11. The anti-accumulation component 20 is used to prevent the shot collected on the inner wall of the collection frame 11 from accumulating in the same position.

[0024] Specifically, when the sandblasting machine 12 finishes shot blasting the inner wall of the steel pipe, it will be pulled back from the tail end. At this time, the adjusting component 13 will drive the driving component 14 to press against the bottom of the inner wall of the steel pipe. When the sandblasting machine 12 is pulled back, the driving component 14 will drive the collecting frame 11 and the recovery frame 10 to rotate clockwise. At this time, the recovery frame 10 can collect the steel shot and cooperate with the covering component 15 to put it into the inner wall of the collecting frame 11 for collection. At the same time, when the collecting frame 11 rotates, it will drive the anti-accumulation component 20 to work, which can help the steel shot on the inner wall of the collecting frame 11 to be arranged to both sides, ensuring that the steel shot on the inner wall of the collecting frame 11 will not accumulate at a certain high place.

[0025] Furthermore, the adjustment assembly 13 includes a connecting ring 131 fixedly connected to the surface of the sandblasting machine 12. A telescopic rod 132 is fixedly connected to the arc surface of the connecting ring 131. A connecting plate 134 is fixedly connected to the lower end of the telescopic rod 132. A spring 133 is sleeved on the surface of the telescopic rod 132. The two ends of the spring 133 are fixedly connected to the connecting ring 131 and the connecting plate 134 respectively. The spring 133 is normally in the unfolded state. Both sides of the collection frame 11 are rotatably connected to the inner wall of the connecting plate 134. The drive assembly 14 includes a first gear 141 fixedly connected to both sides of the collection frame 11. Two extension plates 142 are fixedly connected to the lower surface of the connecting plate 134. Rubber wheels 143 are rotatably connected to the sides of the two extension plates 142 that are far apart from each other. The rubber wheels 143 are "T" shaped. A second gear 144 is fixedly connected to the surface of the rubber wheels 143. The teeth of the first gear 141 mesh with the teeth of the second gear 144. A sealing cap 145 is threadedly connected to the inner wall of the first gear 141 on the left side of the connecting plate 134. The covering assembly 15 includes twelve connecting seats 151 fixedly connected to the inner wall of the collection frame 11. The twelve connecting seats 151 are arranged in pairs. A covering plate 152 is rotatably connected to the sides of the two connecting seats 151 that are close to each other. Six feeding slots 153 are opened on the inner wall of the collection frame 11. All six feeding slots 153 are located below the covering plate 152.

[0026] The telescopic rod 132, in conjunction with the spring 133, helps the rubber wheel 143 of the drive assembly 14 and the collection frame 10 to abut against the bottom of the inner wall of the steel pipe. When the sandblasting machine 12 is collecting the steel shot, the rubber wheel 143, in conjunction with the second gear 144, drives the first gear 141 to rotate the collection frame 11. The collection frame 10 can then rotate to collect the steel shot from the inner wall of the steel pipe. When the collection frame 10 containing the steel shot is at the top of the collection frame 11, the cover plate 152 will rotate under the influence of gravity. As a result, there is no limit on the surface of the feeding trough 153, and the steel shot can fall directly from the inner wall of the collection frame 10 into the collection frame 11 to complete the collection.

[0027] Preferably, the surface of the rubber wheel 143 is provided with several arc-shaped grooves to increase the contact area with the inner wall of the steel pipe.

[0028] It should be noted that the opening of the arc groove can increase the contact area of ​​the rubber wheel 143 with the inner wall of the steel pipe, thereby increasing the friction and improving the driving effect of the rubber wheel 143 on the second gear 144.

[0029] During use, after the sandblasting machine 12 finishes cleaning the inner wall of the steel pipe for the idler roller, the operator pulls the sandblasting machine 12 outward from the tail end. Simultaneously, the recovery frame 10 and the rubber wheel 143 are pressed against the inner wall of the steel pipe by the spring 133 and the telescopic rod 132. When the sandblasting machine 12 moves backward, the rubber wheel 143 rotates due to the pressure against the inner wall of the steel pipe. This causes the rubber wheel 143 to drive the second gear 144 to rotate counterclockwise. Furthermore, the first gear 141, which meshes with the second gear 144, rotates clockwise under the influence of the second gear 144. At the same time, the collection frame 11 rotates synchronously, and the recovery frame 10 on its surface scrapes the steel shot into its interior. When the recovery frame 10 rotates to a high position, the cover plate 15... 2 will rotate, at which point the feeding trough 153 will unfold, and the steel shot inside the recycling frame 10 will fall into the collection frame 11 through the feeding trough 153. At this time, the collection frame 11 will continue to rotate, and the cover plate 152 will continue to flip, and then the cover plate 152 will stick to the surface of the feeding trough 153 to achieve the covering operation. The collected steel shot will not leak from the feeding trough 153. At this time, the collection operation of steel shot on the inner wall of the steel pipe is completed. No manual secondary collection is required. After the steel pipe is cleaned, it can be used directly. After the collection frame 11 is removed from the inner wall of the steel pipe, the operator can rotate the sealing cover 145 to disengage the sealing cover 145 from the first gear 141, and then the steel shot collected inside can be taken out for secondary use.

[0030] Example 2, refer to Figures 1-5This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an anti-accumulation component 20 for the shot blasting cleaning device for the inner wall of the steel pipe of the idler roller, which solves the problem of local accumulation of steel shot inside the collection frame 11. The anti-accumulation component 20 includes a series rod 201 fixedly connected to the side wall of the connecting plate 134. A screw 202 is fixedly connected to the end of the series rod 201 away from the connecting plate 134. The screw 202 is rotatably connected to the first gear 141. An anti-accumulation nut 203 is threadedly connected to the surface of the screw 202. The inner wall of the anti-accumulation nut 203 has balls. Two limiting rods 204 are fixedly connected to the side of the first gear 141 near the anti-accumulation nut 203. The anti-accumulation nut 203 is slidably connected to the two limiting rods 204.

[0031] Specifically, when the first gear 141 rotates, it will simultaneously drive the limit rod 204 and the anti-accumulation nut 203 to rotate. The anti-accumulation nut 203 and the screw 202 are connected by a ball screw drive. When it moves to the extreme position, it is blocked by the first gear 141 and the sealing cover 145 and cannot continue to move. Furthermore, when the nut and the screw 202 are matched with the thread groove again, they will move in the opposite direction, thereby achieving the effect of pushing the steel shot back and forth on the inner wall of the collection frame 11, preventing the accumulation of steel shot.

[0032] Furthermore, a number of separation bristles 205 are fixedly connected to the outer surface of the anti-accumulation nut 203. All of the separation bristles 205 are made of metal and are used to help separate the steel shot arranged on both sides.

[0033] It should be noted that when the separating bristles 205 come into contact with the steel shot, the separating bristles 205 are easily positioned in the gaps between the steel shot, thereby helping the two steel shot to be dispersed to the sides. This allows the steel shot piled up in the middle to be dispersed to the sides, improving the anti-accumulation effect on the steel shot on the inner wall of the collection frame 11.

[0034] In use, when the first gear 141 on the right side of the connecting plate 134 rotates, it will simultaneously drive the limiting rod 204 to rotate. At the same time as the limiting rod 204 rotates, the anti-accumulation nut 203 will also rotate on the surface of the screw 202, allowing for back-and-forth position adjustment during rotation. During the back-and-forth movement of the anti-accumulation nut 203, it will contact the steel shot collected on the inner wall of the collection frame 11. Furthermore, as the anti-accumulation nut 203 moves back and forth, it will push the steel shot, preventing it from accumulating at a certain position and becoming too high, thus preventing the steel shot from entering the collection frame 11. At the same time, when the anti-accumulation nut 203 moves to the end position, it will move in the opposite direction, thereby achieving the effect of arranging the steel shot inside the collection frame 11 to the left and right, facilitating the collection of steel shot inside the collection frame 11, and preventing the cover plate 152 from being unable to rotate due to the accumulation of steel shot.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
