Description
Technical Field
[0001] This utility model belongs to the field of steel rolling technology, and in particular relates to a frame roller conveying device that is easy to maintain. Background Technology
[0002] The stand roll conveyor is installed at the feed and discharge ports of the rolling mill to transport steel billets. Current stand roll conveyors have the following problems: When the rolling mill rolls some non-standard billets (such as short, thick billets, or billets with a center of gravity off-center), the existing rolls, being cylindrical, are prone to jamming or failing to engage with the main rolling mill. Furthermore, the stand rolls have roller bearings at both ends, with gears around the bearings to drive other rolls. External bearing seats are used for fixation, and the installation of adjacent rolls with their bearings and seats requires a certain clearance. The rotating roll's mounting base is connected to the stand by multiple bolts. During rolling, the very large rolling force causes significant impact and vibration, and replacement and maintenance require disassembling multiple bolts, leading to low work efficiency.

[0039] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0040] like Figures 1 to 8 As shown, a frame roller conveying device that is easy to maintain includes: a mounting base 2, on which a mounting plate 201 is fixedly mounted, the upper end surface of which is inclined, and a through hole; a rotating roller 3, the two ends of which are rotatably connected to the two mounting bases 2 respectively; a frame 1, which includes a horizontal bar 101 and two vertical bars 102, the upper ends of which are fixedly connected to the two ends of the horizontal bar 101 respectively, a positioning block 103 fixedly mounted on the vertical bar 102, the lower end surface of which is inclined, the inclined surface of which fits against the inclined surface of the mounting plate 201, and a threaded hole on which a bolt 7 passes through the through hole and is threaded to the inside of the threaded hole; and a support plate 4, the two ends of which are connected to the vertical bars 102, and the lower end surface of the mounting base 2 contacts the upper end surface of the support plate 4.
[0041] A first pad 6 is provided between the inclined surface of the mounting plate 201 and the inclined surface of the positioning block 103;
[0042] There are various models of the first pad 6, and the thickness of the first pad 6 varies with different models. It is used to adjust the horizontal position of the mounting base 2. The horizontal position of the mounting base 2 can be adjusted by replacing the first pad 6 with different models.
[0043] The upper surface of the mounting plate 201 has a first positioning groove 203 that matches the first pad 6, and the first pad 6 is detachably connected to the inner side of the first positioning groove 203.
[0044] A connecting plate 202 is fixedly provided on one side of the upper end of the mounting plate 201. The through hole is a strip-shaped through hole 204, which is vertically arranged in the length direction and is located on the connecting plate 202.
[0045] A connecting rod 5 is provided between the two vertical rods 102. The connecting rod 5 is located at the lower end of the vertical rod 102. There are multiple connecting rods 5, which are evenly arranged along the transport direction. Multiple inserts 402 are fixed at the lower end of the support plate 4. The width of the inserts 402 matches the spacing between adjacent connecting rods 5. The inserts 402 are located between adjacent connecting rods 5. The lower end face of the support plate 4 contacts the upper end face of the connecting rod 5. The inserts 402 play a positioning role for the support plate 4, which facilitates the replacement of the support plate 4.
[0046] The support plate 4 has mounting grooves 401 at both ends that match the mounting base 2. The mounting base 2 is installed inside the mounting groove 401. The mounting groove 401 limits the mounting base 2. A second pad is provided between the bottom end of the mounting groove 401 and the lower end face of the mounting base 2. The height of the mounting base 2 can be adjusted by replacing the second pad with one of different thicknesses.
[0047] The mounting base 2 has mounting holes 205, and the two ends of the rotating roller 3 are rotatably connected to the mounting base 2 through bearings.
[0048] The rotating roller 3 has annular protrusions 301 on its sidewall. There are multiple annular protrusions 301, and annular grooves are formed between adjacent annular protrusions 301. The multiple annular protrusions 301 are evenly arranged along the axis of rotation. There are multiple rotating rollers 3, and the multiple rotating rollers 3 are evenly arranged along the transport direction. The annular protrusions 301 of the rotating roller 3 are located inside the annular grooves of adjacent rotating rollers 3. There is a gap between the annular protrusions 301 of the rotating roller 3 and the annular grooves of adjacent rotating rollers 3. Compared with the traditional cylindrical rotating roller 3, the gap between the rollers can be set to be smaller, which is suitable for gears and bearings of different specifications, thus broadening the scope of application. The projections of the annular protrusions 301 of adjacent rotating rollers 3 in the axial direction of the rotating roller 3 overlap. When transporting shorter steel billets, there will be no jamming or failure to bite into the main rolling mill, thus improving the stability of the use process.
[0049] One end of the rotating roller 3 is fixed with a gear, and a transmission gear is provided between adjacent rotating rollers 3. The transmission gear is rotatably connected to the mounting base 2, and the transmission gear meshes with the gears of two adjacent rotating rollers 3 respectively. The adjacent rotating rollers 3 achieve synchronous rotation through the transmission gear. One end of one rotating roller 3 is connected to the transmission shaft through a bushing. The inner side of the bushing near the transmission shaft has a spline groove, and the end of the transmission shaft near the bushing has a spline structure. The outer edge of the end of the transmission shaft near the bushing has a chamfered structure. The spline connection structure facilitates installation and improves installation efficiency. The chamfered structure of the transmission shaft facilitates the insertion of the transmission shaft into the bushing.
[0050] Work process:
[0051] When this solution is implemented, the stand 1 roll conveying device is located on both sides of the rolling mill, above the multiple rotating rolls 3. The conveying direction of the stand 1 roll conveying device is set perpendicular to the axis of rotation. When it is necessary to disassemble and maintain the rotating rolls 3, the mounting base 2 and the rotating shaft can be removed by loosening the bolts 7. When installing the rotating shaft, the lower end of the mounting base 2 is aligned with the mounting groove 401 and inserted. Then, the bolts 7 are threaded through the strip-shaped through hole 204 and connected to the inside of the threaded hole. The replacement process is convenient. Moreover, the vertical force on the mounting base 2 is borne by the support plate 4 and the positioning block 103, and the bolts 7 are not subjected to vertical force, which extends the service life of the bolts 7.
[0052] Compared to the traditional mounting base 2 and frame 1 connected by bolts 7, this application uses two inclined surfaces to fix the roller 3 with a single bolt 7, which facilitates the later maintenance and upkeep of the roller 3.
[0053] 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.
[0054] 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.
