Description

Technical Field

[0001] The utility model relates to a transversely movable roller table for hot printing of rails, belonging to the technical field of rail rolling in the metallurgical industry. Background Art

[0002] During the hot rolling process of the rails, a thermal printer is required to emboss the rail serial number with a certain depth on the upper surface of the rail waist. The rollers under the rails play a supporting role during printing. In actual production, it is found that due to lateral relative sliding between the rollers and the rails during printing, the wear of the area where the rollers and the rails are in contact increases, and its supporting function gradually weakens, causing the printing depth to gradually decrease. When the printing depth cannot meet the product standard requirements, the rollers need to be replaced as a whole, but other areas of the rollers that are not in contact with the rails are not worn, resulting in a great waste of rollers. At the same time, disassembling and assembling the rollers is time-consuming and labor-intensive, affecting production operation time. Utility Model Content

[0003] The utility model aims to provide a transversely movable roller for rail thermal printing, which can improve the utilization rate of the roller working surface, extend the service life of the roller, and solve the problems existing in the background technology.

[0004] The technical solution of the utility model is:

[0005] A transversely movable roller for rail thermal printing comprises a roller, a bearing seat, a fixed base, fixing bolts and elongated holes. Both ends of the roller are rotatably connected to the bearing seats through bearings, each bearing seat is fixed to the fixed base through fixing bolts, and the fixed base is provided with elongated holes matching with the fixing bolts.

[0006] There are two long holes on the fixed base that match the fixing bolts, and the two long through holes are arranged parallel to the central axis of the roller table.

[0007] Each bearing seat is fixed on the fixed base by four fixing bolts, and the four fixing bolts are evenly distributed on the two long holes.

[0008] Two rows of anchor bolt holes are arranged under the fixed base, and the fixed base is fixed on the foundation through the anchor bolts.

[0009] The beneficial effects of the utility model are as follows: the utility model has a simple structure, is stable and durable, and changes the contact area between the roller and the rail by lateral movement of the roller on the fixed base, thereby improving the utilization rate of the roller working surface and extending the service life of the roller.

[0016] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0017] See attached Figure 1-5 A transverse roller for rail thermal printing comprises a roller 1, a bearing seat 2, a fixed base 3, fixing bolts 4 and long holes 5. Both ends of the roller 1 are rotatably connected to the bearing seat 2 through bearings, each bearing seat 2 is fixed to the fixed base 3 through fixing bolts 4, and the fixed base 3 is provided with long holes 5 matched with the fixing bolts 4.

[0018] In this embodiment, refer to the attached Figure 1 A transverse roller table for rail thermal printing is composed of a roller table 1, a bearing seat 2 and a fixed base 3. Both ends of the roller table 1 are connected to the bearing seat 2 through a rotating shaft and can rotate freely in the bearing seat 2. The bearing seat 2 is fixed to the fixed base 3 by fixing bolts 4.

[0019] Figure 1-4 It is shown that two rows of parallel anchor bolt holes 6 are opened under the fixed base 3, and the fixed base 3 can be fixed to the foundation through the two rows of anchor bolts; two long holes 5 are opened on the fixed base 3, and the two long holes 5 are arranged parallel to the central axis K of the roller table, so that the bearing seat 2 and the fixing bolts 4 can move laterally on the fixed base 3.

[0020] See attached Figure 1 The roller 1 below the rail 7 plays a supporting role. When the rail 7 is printed, the roller 1 and the rail 7 will slide relative to each other horizontally, which will increase the contact area between the roller 1 and the rail 7, that is, the wear point D. Its supporting function gradually weakens, causing the printing depth to gradually decrease. When the wear point D of the roller 1 is worn to a certain extent, loosen the fixing bolts 4, move the roller 1 and the bearing seat 2 horizontally for a certain distance, and then re-tighten the fixing bolts 4 to move the roller wear point D to the area outside the center line L of the rail, so that the roller 1 can be used in sections, as shown in the attached figure. Figure 5As shown, the utilization rate of the roller working surface is improved and the service life of the roller is extended.
