[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] like Figures 1-7As shown, an easy-to-maintain alignment device includes: two movable plates 1 forming an alignment channel between them; a connecting plate 6 detachably connected to the movable plates 1; multiple liners 7 detachably connected to the connecting plate 6; push rods 3 movably connected to a track plate 9, which is fixedly connected to a base 10; each movable plate 1 has two push rods 3 corresponding to its ends, which move synchronously via a synchronizing rod 4; and a drive assembly for driving the movable plates 1 to move. The alignment channel is located above the roller conveyor.

[0045] The movable plate 1 includes: a base plate 101, with a first side plate 104 and a second side plate 102 fixedly mounted on both sides of the upper surface of the base plate 101, the second side plate 102 being connected to the push rod 3, and a positioning groove 107 formed on the upper end of the first side plate 104; and a reinforcing plate 106, the lower end of which is fixedly connected to the base plate 101, and both ends of which are fixedly connected to the first side plate 104 and the second side plate 102, respectively. Each positioning groove 107 corresponds to two reinforcing plates 106. Two reinforcing plates 106 are located on both sides of the positioning groove 107, and the distance between the two reinforcing plates 106 matches the width of the positioning groove 107. A positioning plate 602 corresponding to the groove is fixed on the connecting plate 6. The width of the positioning plate 602 matches the width of the groove. The positioning plate 602 is installed inside the groove. The lower end of the positioning plate 602, near the connecting plate 6, has a limiting groove 605 that matches the first side plate 104. The first side plate 104 is located inside the limiting groove 605. The positioning plate 602 allows for quick positioning of the moving plate 1, improving the efficiency of replacement and maintenance.

[0046] Furthermore, the positioning plate 602 has a through hole one, and the reinforcing plate 106 has a through hole two 604, with the limiting pin passing through the through hole one and the through hole two 604 in sequence.

[0047] The upper end of the connecting plate 6 is fixed with a lifting lug 603, which facilitates the hoisting of the connecting plate 6.

[0048] In other embodiments, the limiting pin is a mounting bolt 8, which passes through through hole one and through hole two 604 in sequence and is then threadedly connected to the nut; in this embodiment, there are four positioning plates 602, and the disassembly and installation of the connecting plate 6 can be completed by rotating the four mounting bolts 8, which improves work efficiency.

[0049] The liner plate 7 has multiple threaded holes 701, and the connecting plate 6 has corresponding connecting holes 601. Connecting bolts are installed in the connecting holes 601, and the connecting bolts pass through the connecting holes 601 and are threaded into the inner side of the threaded holes 701. There are multiple liner plates 7, and the two edges of the end faces of the multiple liner plates 7 adjacent to the centering channel are chamfered to prevent the steel billet from impacting the edges of the liner plates 7. With multiple liner plates 7, if one liner plate 7 is damaged, only the damaged one needs to be replaced, reducing material waste.

[0050] The end of the movable plate 1 near the feed inlet of the centering channel is inclined away from the centering channel to form an inclined plate 103. A wear-resistant plate 105 is provided on the inclined plate 103, and the wear-resistant plate 105 is detachably connected to the inclined plate 103.

[0051] The driving component is a hydraulic cylinder 2. The housing of the hydraulic cylinder 2 is fixedly connected to the base 10. The output shaft of the hydraulic cylinder 2 is connected to the moving plate 1. Each moving plate 1 is provided with a hydraulic cylinder 2.

[0052] Gears are fixed at both ends of the synchronizing rod 4, which is rotatably connected to the base 10. A ruler is fixed on the push rod 3, which meshes with the gears. The gears are installed inside the gearbox 5. When one of the push rods 3 moves, it drives the gear and the synchronizing rod 4 to rotate. The gear at the other end of the synchronizing rod 4 drives the other push rod 3 to move, thus achieving synchronous movement of the two push rods 3. This ensures the translation effect of the moving plate 1 and, consequently, the centering effect of the steel billet.

[0053] A mounting shaft 301 is fixedly mounted on the push rod 3. A roller 303 is mounted on the outer side of the mounting shaft 301. The roller 303 is rotatably connected to the mounting shaft 301 via a bearing 302. A strip-shaped hole is formed on the track plate 9 along the length of the push rod 3. The roller 303 is located inside the strip-shaped hole. A pad 304 is fixedly mounted on the lower end face of the strip-shaped hole. The distance between the pad 304 and the upper end face is greater than the diameter of the roller 303. The roller 303 contacts the pad 304. Both the roller 303 and the pad 304 are structural components made of wear-resistant steel. The roller 303 reduces friction and extends the service life of the device. The strip-shaped hole limits the vertical movement of the push rod 3. The pad 304 prevents wear on the inner side of the strip-shaped hole. Replacing the pad 304 can extend the service life of the track plate 9.

[0054] There are two track plates 9, with the push rod 3 located between them. First sliding plates 305 are fixed to both sides of the push rod 3, and second sliding plates 901, corresponding to the first sliding plates 305, are fixed to the end face of the track plate 9 adjacent to the push rod 3. The first sliding plates 305 and second sliding plates 901 are made of copper. The first sliding plates 305 and second sliding plates 901 prevent the push rod 3 from wobbling horizontally, improving the stability of the push rod 3 during movement. The liner plate 7 is made of wear-resistant steel.

[0055] Work process:

[0056] When this scheme is implemented, the steel billet moves on the roller conveyor and enters the centering channel under the guidance of the inclined plate 103. The two moving plates 1 on both sides move towards each other under the push of the hydraulic cylinder 2 to complete the centering operation of the steel billet.

[0057] The connecting plate 6 is detachably connected to the movable plate 1. Compared with the traditional liner 7 being directly connected to the movable plate 1, only the connecting plate 6 needs to be removed during maintenance, which improves work efficiency compared to removing multiple liners 7.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
