[0020] Example 1

[0021] In order to make the present invention more clear, an eight-shaped roller cover device of the present invention is further described below. The specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0022] See also Figure 1 , Figure 2 and Figure 4 , an eight-shaped roller cover device, comprising frames 1 on both sides and a group of rollers 2 arranged between the frames 1, a gap 2a is left between two adjacent rollers 2, and a roller cover 3 that cooperates with each other is arranged in the gap 2a, characterized in that:

[0023] See also Figures 1 to 5 The roller cover 3 includes a bottom leg 31, a mounting bracket 32, a support block 33 and a guide plate 34;

[0024] See also Figure 5 The bottom legs 31 are fixed on the frames 1 on both sides respectively, and a mounting bracket 32 ​​is connected between the two bottom legs 31. The mounting bracket 32 ​​is a rectangular frame structure, and a hollow portion 32a is provided in the middle thereof. The mounting bracket 32 ​​and the roller table 2 are arranged parallel to each other, so as to facilitate the detection of the lower surface of the roller table by the detection equipment;

[0025] See also Figure 1 and Figure 4 The inner side of the mounting bracket 32 ​​is connected to a trapezoidal support block 33, and the outer side is connected to a vertical plate 4. An inclined guide plate 34 is connected between the vertical plate 4 and the support block 33 on each side. A meter inspection opening 33a is provided between the two support blocks 33, and the axis of the meter inspection opening 33a is parallel to the axis of the hollow portion 32a of the mounting bracket 32;

[0026] The lower side of the guide plate 34 is connected to the top of the vertical plate 4, and the higher side thereof is connected to the top of the support block 33. A detection gap 34b is provided between the two guide plates 34. The detection gap 34b corresponds to the surface inspection opening 33a to facilitate lighting and photography of the surface under the roller table.

[0027] The axes of the two guide plates 34 are arranged parallel to the roller 2. The side of each guide plate 34 close to the roller 2 is the lower side, and the other side is the higher side. A detection gap 34b is provided between the higher sides of the two guide plates 34. The detection gap 34b between the guide plates 34 is the same as the width of the surface inspection opening 33a of the support block 33.

[0028] See also Figure 4, the included angle α between the guide plate 34 and the horizontal direction is 10°, so as to cooperate with the guide plate for fixed connection;

[0029] See also Figure 1 and Figure 4 A group of guide wheel seats 5 are fixed on the mounting bracket 32 ​​at equal intervals. The guide wheel seats 5 are arranged between the vertical plate 4 and the support block 33. Each guide wheel seat 5 is connected to a guide wheel 6 that matches with each other. The guide plate 34 is provided with a group of guide wheel openings 34a that match with the guide wheel 6. The upper part of the guide wheel 6 extends out of the upper surface of the guide plate 34 through the guide wheel openings 34a to reduce the collision and friction between the steel plate and the guide plate when the steel plate passes through.

[0030] The horizontal plane where the higher side of the guide plate 34 is located is lower than the horizontal plane where the highest point of the roller 2 is located, and the horizontal plane where the highest point of the guide wheel 6 is located is also lower than the horizontal plane where the highest point of the roller 2 is located, so as to ensure that the steel plate will not rub against the guide plate during operation.

[0031] The device of the present invention can be specifically manufactured according to the following steps:

[0032] (1) Confirm the working conditions on site, measure and confirm the dimensions of the existing roller cover and record them;

[0033] (2) Focus on confirming the distance difference between the highest surface of the top layer of the cover plate and the highest point of the roller to ensure that the steel plate will not rub against the cover plate during normal operation;

[0034] (3) According to the working requirements of the on-site roller table under-surface inspection equipment, confirm the actual width of the opening gap required on the top layer of the cover plate;

[0035] (4) After the size is confirmed, the plane of the top layer of the cover plate is changed from the original plane to an "eight" shape;

[0036] (5) The two sides of the "eight"-shaped plane adopt a certain angle, which can make the steel plate have an upward guide angle when passing through, ensuring that the steel plate can pass through the opening gap;

[0037] (6) In order to prevent the steel plate from being directly impacted by the panels on both sides of the "eight" shape due to long-term damage, a certain number of needle bearings are installed on both sides of the panels as guide wheels as needed to reduce the collision and friction between the steel plate and the panels;

[0038] (7) Because the roller steel plate runs forward and backward, the two sides of the "eight" shaped plane need to adopt the same angle;

[0039] (8) The angles on both sides of the "eight"-shaped plane are determined according to the actual plate shape. In this embodiment, they are determined based on the maximum deformation of 40 mm provided by the user.

[0040] In actual operation, the steel plate must not stay at the opening, and the running speed of the steel plate here shall not be less than 0.5m / s.

[0041] The device of the present invention can be applied between the rollers of the production line to solve the gap problem between the rollers and prevent the steel plates from being bumped during transportation, especially the steel plates with serious plate curvature, which may be embedded in the larger gap between the rollers after the head or tail swings up and down during transportation. In addition, two new intelligent surface inspection and testing equipment are installed on the finishing line of the thick plate coil plant. Since surface inspection and photography equipment are installed above and below the roller opening, the traditional roller cover is improved and an eight-shaped cover is adopted, which fundamentally solves the risk of the buckled steel plates falling into the opening, while ensuring the viewing angle of the light source of the surface inspection equipment and the camera, and the application is very good.

[0042] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
