Description

Technical Field

[0001] The utility model relates to the field of continuous casting equipment. More specifically, the utility model relates to a movable roller table heat preservation cover. Background Art

[0002] At present, most steel mills directly send the billets obtained through processes such as the mold, secondary cooling chamber, and straightening machine to rolling through the conveyor roller table or send them to the slow cooling pit for slow cooling during continuous casting operations. The billets are exposed on the conveyor roller table. If no heat preservation treatment is done to the billets, it will cause relatively large surface temperature loss of the billets and many adverse effects will occur, such as affecting the quality of the billets and increasing the hot rolling energy consumption by heating the cast billets in the subsequent hot rolling stage. Therefore, it is necessary to set a heat preservation cover on the conveying line. However, the current billet heat preservation covers are directly covered on the roller table. When inspecting the conveyor roller table or the billets on the conveyor roller table later and the heat preservation cover needs to be moved, it can only be lifted and moved by a crane. The hoisting process not only takes a long time, but also the accuracy is difficult to guarantee, and it is easy to collide with other equipment such as the conveyor roller table in the workshop. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a movable roller table heat preservation cover, which is convenient for horizontal movement, so as to facilitate the inspection of the conveyor roller table at any time.

[0017] The following further detailed description of the present utility model is provided in conjunction with the drawings, so that those skilled in the art can implement it with reference to the description in the specification.

[0018] It should be noted that in the description of the present utility model, the orientation or positional relationship indicated by the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0019] Figure 1 A movable roller path heat insulation cover provided by an embodiment of the present utility model includes:

[0020] A cover body 1 with openings at both ends, and a heat insulation layer 2 is provided on the inner wall thereof. A lifting lug 3 is provided at the upper end of the cover body 1;

[0021] A plurality of groups of rollers 4 are arranged at intervals along the length direction of the cover body 1 at the lower end of the cover body 1;

[0022] Both of the two tracks 5 are provided with rollers 4 slidably thereon.

[0023] In this embodiment, the two tracks 5 are respectively laid on both sides of the conveying roller path. The cover 1 is lifted above the conveying roller path by the lifting lugs 3. After being lowered to cover the conveying roller path, the rollers 4 are slidably arranged on the tracks 5 below it. Under the action of an external force, the cover 1 can slide along the tracks 5, thereby sealing the conveying roller path. The heat insulation layer 2 on the inner wall of the cover 1 can keep the inside of the cover 1 warm, so as to keep the billet on the conveying roller path warm. When it is necessary to inspect the conveying roller path or the billet on the conveying roller path, only need to push the cover 1 to make the cover 1 slide along the tracks 5 to expose the conveying roller path, and the staff can inspect the conveying roller path or the billet on the conveying roller path. Compared with the existing method of lifting the cover 1, it saves time and effort.

[0024] Preferably, as another embodiment of the present invention, the inner wall of the cover 1 has a plurality of filling cavities, and a sealing mesh plate 6 is detachably arranged at the opening of the filling cavity, and heat insulation materials are filled inside the filling cavity.

[0025] In this embodiment, the heat insulation layer 2 can be made of heat insulation cotton. At present, generally, the heat insulation cotton is fixed on the inner wall of the cover 1 through a wire mesh. When some of the heat insulation cotton inside the cover 1 is damaged, it is rather troublesome to replace it. It is necessary to remove the wire mesh, cut off the damaged part of the heat insulation cotton and replace it, and then fix the wire mesh again. The whole process is time-consuming. In this embodiment, by arranging a plurality of wire meshes on the inner wall of the cover 1 to separate a plurality of filling cavities, the opening of the filling cavity is provided with an inward flanging corresponding to the sealing mesh plate 6, and then heat insulation cotton is filled in each filling cavity, and then the sealing mesh plate 6 is fixed at the opening of the filling cavity. The sealing mesh plate 6 and the inward flanging can be threadedly connected through mounting bolts and nuts. When the heat insulation cotton is damaged subsequently, only need to replace the heat insulation cotton in the filling cavity where the damaged part is located.

[0026] Preferably, as another embodiment of the present invention, as Figures 2 - 3 shown, a notch 7 corresponding to the roller 4 is provided at the lower end of the cover 1, an installation plate 8 is connected to the upper end of the roller 4, a positioning plate 9 corresponding to the installation plate 8 is provided on the top wall of the notch 7, and the installation plate 8 is connected to the positioning plate 9.

[0027] In this embodiment, in order to prevent the roller 4 at the lower end of the cover 1 from sliding on the track 5, causing the cover 1 to move, a height adjustment mechanism is provided in the notch 7 at the lower end of the cover 1. The mounting plate 8 and the positioning plate 9 are connected by the height adjustment mechanism, and a groove corresponding to the track 5 is provided at the lower end of the cover 1. Specifically, the height adjustment mechanism includes a plurality of threaded rods 10. The threaded rods 10 vertically penetrate through the mounting plate 8 slidably. The upper end of the threaded rod 10 is connected to the positioning plate 9, and the lower end thereof is connected with a stop block 11. Upper nuts 12 and lower nuts 13 are threadedly mounted on the threaded rods 10. The upper nuts 12 and the lower nuts 13 are respectively located above and below the mounting plate 8. When the roller 4 needs to be used, first lift the cover 1 and hold against the mounting plate 8. Tighten the lower nuts 13 on the plurality of threaded rods 10 downward until they abut against the stop block 11, and the lower end of the roller 4 moves below the notch 7. Then lower the mounting plate 8. The mounting plate 8 descends under the action of gravity until it abuts against the lower nuts 13. Then tighten the upper nuts 12 downward until they abut against the mounting plate 8, and the mounting plate 8 can be fixed on the plurality of threaded rods 10. When the roller 4 does not need to be used, first lift the cover 1, tighten the upper nuts 12 upward until they abut against the positioning plate 9, and then lift the mounting plate 8 upward until it abuts against the upper nuts 12. At this time, the lower end of the roller 4 moves upward into the notch 7. Then tighten the lower nuts 13 upward until they abut against the mounting plate 8, and the mounting plate 8 can be fixed on the plurality of threaded rods 10. At this time, lower the cover 1 again and place the cover 1 on the ground. At this time, the track 5 is received in the corresponding groove.

[0028] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the embodiments shown and described herein.
