[0002] The centering device plays an important role in a hot-rolled billet equipment, and is a key equipment for controlling the left and right positions of a billet and preventing the occurrence of a deviation tower shape. Since the centering device controls the whole lining plate by a servo hydraulic cylinder, the position of the billet before entering a pinch roll and after entering the pinch roll is controlled by pressing the lining plate against the billet, and the speed of the billet can reach 8-15 m / s in the working process, which makes the lining plate in contact with the billet prone to very serious wear. After the wear, the whole centering device cannot normally play its function. According to different output, the lining plate needs to be replaced every 2-3 shifts, and the work of replacing the lining plate accounts for a large proportion in the maintenance of the hot-rolled billet production line. The existing lining plate replacement process needs to use multiple bolts to be connected with a hydraulic cylinder driving frame, the connection process is very complex, the working efficiency is low, the production line needs to be stopped in the process of replacing the lining plate, and the working efficiency of the hot-rolled billet is seriously limited.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Example 1:

[0036] like Figure 1 As shown, a liner plate 4 installation structure includes an installation frame 2 and a liner plate 4. The upper end of the liner plate 4 is provided with an upper hook 11, and the lower end of the liner plate 4 is provided with a lower hook 12. The openings of the upper hook 11 and the lower hook 12 are arranged facing each other.

[0037] A clamping block 14 corresponding to the opening of the upper hook 11 is fixed at the upper end of the frame 2, and the clamping block 14 clamps the inner side of the upper hook 11.

[0038] The frame 2 is provided with a rotating shaft 6, which is rotatably connected to the frame 2. A corresponding limiting pin 13 is fixed on the rotating shaft 6, which is the opening of the lower hook 12. The limiting pin 13 presses against the inner side of the lower hook 12.

[0039] A top plate 7 is fixed at the end of the rotating shaft 6 away from the liner plate 4, and a handle 9 is fixed on the top plate 7; the handle 9 facilitates the rotation of the rotating shaft 6.

[0040] The top plate 7 has a top threaded hole corresponding to the frame 2. The top threaded hole is equipped with a top bolt 8. The top bolt 8 is threadedly connected to the top plate 7 and the top bolt 8 tightens the frame 2.

[0041] The frame 2 has a tightening groove 201 corresponding to the tightening bolt 8, and the tightening bolt 8 tightens to the bottom end of the tightening groove 201. The tightening groove 201 limits the locking bolt and prevents the tightening plate 7 from rotating.

[0042] The tightening bolt 8 is equipped with a locking nut 10, which is threadedly connected to the tightening bolt 8 and tightens the top plate 7. The locking nut 10 serves to lock the tightening bolt 8 and prevent the locking nut 10 from rotating.

[0043] A connecting block 15 is fixed on the liner plate 4. A connecting thread hole is opened on the connecting block 15. A corresponding hanging plate 5 is provided on the liner plate 4. A connecting hole corresponding to the connecting thread hole is opened on the hanging plate 5. A connecting bolt is provided corresponding to the connecting hole. The connecting bolt passes through the connecting hole and is threadedly connected to the connecting block 15.

[0044] The liner 4 is detachably connected to the hanging plate 5 by connecting bolts. The upper end of the hanging plate 5 is fixed with an upper hook 11, and the lower end of the hanging plate 5 is fixed with a lower hook 12.

[0045] A copper sleeve 16 corresponding to the rotating shaft 6 is fixed on the frame 2, and the rotating shaft 6 is rotatably connected to the copper sleeve 16.

[0046] The upper hook 11 has an L-shaped structure with an inclined surface at the opening. The clamping block 14 fits against the inclined surface of the upper hook 11 and clamps against the inclined surface of the upper hook 11. The clamping block 14 is detachably connected to the frame 2 by bolts. When the clamping block 14 is worn, it can still clamp the upper hook 11 under the action of the inclined surface, and the position of the hanging plate 5 will not change.

[0047] The lower hook 12 has an L-shaped structure with an inclined surface at its opening. A second clamping block 21 is provided on the limiting pin 13, which fits against the inclined surface of the lower hook 12. The clamping block 21 is detachably connected to the frame 2 via bolts. Even when the clamping block 21 wears down, it still effectively clamps the upper hook 11 under the action of the inclined surface, and the position of the hanging plate 5 remains unchanged.

[0048] Both clamping block 14 and clamping block 21 are structural components made of wear-resistant steel, which extends their service life.

[0049] Work process:

[0050] When implementing this solution, the liner plate 4 and the hanging plate 5 are connected together by connecting bolts. The process of installing the hanging plate 5 is as follows: rotate the rotating shaft 6 so that the limiting pin 13 faces upward, align the opening of the upper hook 11 with the tightening block 14, place the lower hook 12 in the corresponding position of the limiting pin 13, rotate the rotating shaft 6, and the limiting pin 13 is inserted into the opening of the lower hook 12. Then tighten the tightening bolt 8. During this process, the second top block tightens the inclined surface of the lower hook 12, and the first top block tightens the inclined surface of the upper hook 11, thus completing the installation of the hanging plate 5. The process of disassembling the hanging plate 5 is the reverse. When the liner plate 4 needs to be replaced, the liner plate 4 is connected to another hanging plate 5 in advance. The replacement process of the hanging plate 5 is convenient and improves work efficiency.

[0051] By rotating the limit pin 13, the top block tightens the upper hook 11, and the limit pin 13 tightens the lower hook 12, making the replacement process of the hanging plate 5 convenient and improving work efficiency.

[0052] Example 2:

[0053] like Figures 2 to 4 As shown, a billet centering device includes a roller conveying assembly and two liner plate 4 mounting structures. Each liner plate 4 mounting structure is equipped with a hydraulic cylinder 3 that drives the movement of the liner plate 4 mounting structures. The two liner plate 4 mounting structures are correspondingly arranged, forming a centering channel between them. The liner plate 4 mounting structure is the same as that in Embodiment 1. The billet moves in the centering channel above the roller conveying assembly, and the hydraulic cylinder 3 drives the liner plate 4 to move, limiting the billet and achieving the centering operation.

[0054] The liner 4 has a groove 401 corresponding to the rotating roller 1 in the roller conveyor assembly. The groove 401 is an arc-shaped groove. The hanging plate 5 is provided with a positioning block 17, and the frame 2 is provided with two adjusting blocks 19. The positioning block 17 is installed between the two adjusting blocks 19. The adjusting block 19 has an adjusting threaded hole corresponding to the positioning block 17. An adjusting bolt 20 is provided in the adjusting threaded hole. The adjusting bolt 20 is threadedly connected to the adjusting block 19. The adjusting bolt 20 tightens the positioning block 17. By rotating the adjusting bolt 20, the positioning block 17 is moved, which causes the arc-shaped groove to align with the rotating roller 1.

[0055] The adjusting bolt 20 is equipped with a locking nut 18, which is threadedly connected to the adjusting bolt 20. The locking nut tightens the adjusting plate. After the positioning block 17 is positioned, the locking nut 18 locks the adjusting bolt 20 to prevent it from rotating.

[0056] The edge of the positioning block 17 near the end face of the adjusting block 19 is chamfered. The chamfered structure of the positioning block 17 plays a guiding role in the process of inserting the positioning block 17 between the two adjusting blocks 19, making the installation process more convenient.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them.
