[0002] The roller is the main working part and tool on the rolling mill that causes continuous plastic deformation of the metal. The roller is mainly composed of a roller body, a roller neck and a shaft head. The roller body is the middle part of the roller that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roller neck is installed in the bearing and transmits the rolling force to the frame through the bearing seat and the pressing device. The shaft head at the transmission end is connected to the gear seat through a connecting shaft, which transmits the rotational torque of the motor to the roller.

DETAILED DESCRIPTION

[0027] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0028] See also Figure 1-2 According to an embodiment of the utility model, a concave-convex roller transportation device includes a base frame 1, a support plate 2 symmetrically arranged along the center of the base frame 1 is fixedly installed on the top of the base frame 1, a cross plate 3 is fixedly installed on the top end of the support plate 2, and a support frame 4 is fixedly installed between the cross plates 3 on both sides. The support frame 4 is used to support the concave-convex roller, and fixed plates 5 are also fixedly installed at both ends of the top of the base frame 1. A stabilizing mechanism 6 for stabilizing the end of the concave-convex roller is fixedly installed at the top center of the fixed plate 5. In order to keep the cross plate 3 stable, columns 7 are also fixedly installed at both ends of the bottom of the cross plate 3. The column 7 is perpendicular to the cross plate 3, and the bottom end of the column 7 is fixedly installed on the base frame 1.

[0029] The concave-convex roller to be transported is hoisted on the support frame 4, and then the stabilizing mechanism 6 is adjusted to stabilize the end of the concave-convex roller, so as to ensure the stability of the concave-convex roller during transportation.

[0030] In order to facilitate the device to drive the concave and convex rollers to move and position, in the present embodiment, brackets 8 are fixedly installed at the four corners of the bottom of the base frame 1, a walking wheel 9 is rotatably installed on the bracket 8 at one end of the bottom of the base frame 1, a universal wheel 10 is installed on the bracket 8 at the other end, and a brake plate 11 is installed on the universal wheel 10 for locking the movement of the universal wheel 10.

[0031] In order to facilitate the fixed installation of the support plate 2 on the base frame 1, in this embodiment, a fixed angle plate 12 for fixing the support plate 2 is fixedly welded on the top of the base frame 1, and the fixed angle plates 12 are relatively arranged. The support plate 2 is inserted between the relatively arranged fixed angle plates 12, and the support plate 2 can be fixed by using locking screws and other workpieces.

[0032] See also Figure 3 In order to enable the support frame 4 to support the concave-convex roller for lifting and lowering adjustment, so as to facilitate the adjustment of the stabilizing mechanism 6, in this embodiment, the support frame 4 includes a crossbeam 41 fixedly installed between the cross plates 3 on both sides of the top of the base frame 1, and the two ends of the crossbeam 41 are fixedly installed with connecting pieces 42 for being fixedly installed on the cross plates 3, and a fixing frame 43 is fixedly installed at the bottom center of the crossbeam 41, and the fixing frame 43 is perpendicular to the crossbeam 41, and a hydraulic cylinder 44 is fixedly installed on the fixing frame 43, and a telescopic shaft (not shown) is provided on the top of the hydraulic cylinder 44, and the top end of the telescopic shaft passes through the crossbeam 41, and a support block 45 is fixedly installed on the top of the telescopic shaft, and a support plate 46 is fixedly installed on the top end of the support block 45. The support plate 46 is used to support the concave-convex roller, so in this embodiment, the two ends of the support plate 46 in the length direction are arranged opposite to the stabilizing mechanism 6 on both sides, and the height of the support plate 46 can be adjusted by the hydraulic cylinder 44, so that the concave-convex roller can be lifted and lowered, so as to facilitate the transportation of the concave-convex roller to the transportation equipment.

[0033] In order to keep the concave-convex roller stable when placed on the support plate 46, in this embodiment, an arc pad 47 is fixedly mounted on the support plate 46, and the arc pad 47 is arranged along the length direction of the support plate 46. The top inner arc surface of the arc pad 47 can support the middle outer wall of the concave-convex roller, and can have a certain stability when the stabilizing mechanism 6 does not clamp the end of the concave-convex roller. At the same time, the arc pad 47 in this embodiment can be set as a rubber pad with buffering flexibility, which can also have a certain buffering performance for the concave-convex roller.

[0034] See also Figure 4-6In order to enable the stabilizing mechanism 6 to effectively clamp the end of the concave-convex rolling roller, in this embodiment, the stabilizing mechanism 6 includes a vertical plate 601 fixedly installed at the top center of the fixing plate 5, and a relatively arranged outer shell plate 602 is fixedly installed at the top end of the vertical plate 601, and a rack rod 603 is vertically arranged at the inner center of the outer shell plate 602, and gears 604 are meshed on both sides of the rack rod 603. The gears 604 are rotatably installed on the outer shell plate 602, and an extension handle 605 is integrally provided at the bottom of the side where the two gears 604 are away from each other, and the end of the extension handle 605 away from the gear 604 is movably connected to a clamping rod 606, and a connecting rod 607 is movably installed at the top center of the outer shell plate 602, and the bottom of the clamping rod 606 is bent, and the end of the connecting rod 607 away from the outer shell plate 602 is hinged to the bending part of the clamping rod 606. By applying a pulling force to the rack rod 603 through an external force, the rack rod 603 will drive the gear 604 to rotate, and the rotation directions of the two gears 604 are opposite. When the gear 604 rotates, it will drive the clamping rod 606 to move through the extension handle 605, and the bending part of the clamping rod 606 is connected to the outer shell plate 602 through the connecting rod 607. Therefore, when the clamping rod 606 moves, it will rotate relative to the end of the extension handle 605. If the end of the concave-convex roller is arranged between the two clamping rods 606 at this time, the end of the clamping rod 606 will approach the end of the concave-convex roller until the end of the clamping rod 606 clamps the outer wall of the end of the concave-convex roller, thereby ensuring the stability of the end of the concave-convex roller.

[0035] In order to enable the clamping rod 606 to automatically adjust and clamp the end of the concave-convex roller when the concave-convex roller is raised or lowered on the support frame 4, in the present embodiment, a vertical rod 609 is fixedly installed at the top end of the rack rod 603, and the vertical rod 609 and the rack rod 603 are arranged in a colinear manner, and a mounting plate 610 is fixedly installed at the top end of the vertical rod 609, and an annular plate 608 is fixedly installed at the top center of the outer shell plate 602, and the vertical rod 609 passes through the center of the annular plate 608, and a reset spring 612 is provided between the annular plate 608 and the mounting plate 610, and the reset spring 612 is sleeved on the outside of the vertical rod 609. When the end of the concave-convex roller is located between the two clamping rods 606, the height of the concave-convex roller is adjusted by the hydraulic cylinder 44. When the end of the concave-convex roller contacts the mounting plate 610 and continues to press down, the mounting plate 610 will drive the rack rod 603 to move downward through the vertical rod 609, and the mounting plate 610 will also compress the reset spring 612, thereby realizing the adjustment of the clamping rod 606, so as to realize automatic clamping of the concave-convex roller when it is raised or lowered. When the concave-convex roller rises, its end leaves the mounting plate 610. At this time, the reset spring 612 will reset and drive the mounting plate 610 to rise through the annular plate 608. At the same time, the mounting plate 610 drives the rack rod 603 to rise through the vertical rod 609, thereby making the clamping rod 606 away from the outer wall of the concave-convex roller, thereby loosening the end of the concave-convex roller and facilitating the transportation of the concave-convex roller.

[0036] In order to enable the end of the concave-convex roller to be effectively clamped by the mounting plate 610 and the clamping rod 606, in this embodiment, a support wheel 611 is rotatably mounted on the top of the mounting plate 610, a mounting frame 613 is fixedly mounted on the top of the clamping rod 606 facing the support wheel 611, and a clamping wheel 614 is rotatably mounted on the mounting frame 613.

[0037] In order to make the rack rod 603 more stable during lifting and lowering adjustment, in the present embodiment, an extension rod 615 is fixedly installed at the bottom end of the rack rod 603, and the extension rod 615 and the rack rod 603 are arranged in a colinear manner. A fixed block 616 is provided in the middle of the extension rod 615, and a lifting block 618 is fixedly installed at one end of the fixed block 616 facing the vertical plate 601. A guide hole 619 is opened in the center of the lifting block 618, and a guide rod 620 is penetrated through the guide hole 619, and the bottom end of the guide rod 620 is fixedly installed on the fixed plate 5.

[0038] When the rack rod 603 is raised or lowered, the extension rod 615 will be driven to be raised or lowered synchronously. The lifting of the extension rod 615 will drive the lifting block 618 to be raised or lowered synchronously through the fixed block 616. The lifting block 618 can then move up and down stably along the guide rod 620 through the guide hole 619, thereby ensuring that the rack rod 603 can move up and down stably.

[0039] In order to ensure that the fixing block 616 is stably installed on the extension rod 615, in this embodiment, a through hole is opened in the center of the fixing block 616 (not shown in the figure), and a connecting sleeve 617 is fixedly installed at the top center of the fixing block 616, the connecting sleeve 617 is arranged opposite to the through hole, and the fixing block 616 is fixedly installed on the extension rod 615 through the connecting sleeve 617.

[0040] In order to prevent the extension rod 615 from hitting the fixing plate 5 when it descends, in this embodiment, a through hole 51 is opened in the center of the fixing plate 5, and the through hole 51 is arranged opposite to the bottom end of the extension rod 615.

[0041] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0042] In actual application, the base frame 1 is moved to the location of the concave-convex roller, and then the direction of the base frame 1 is adjusted, and the universal wheel 10 is locked with the brake plate 11. At this time, the concave-convex roller to be transported is hoisted on the arc pad 47. When the concave-convex roller is stable relative to the arc pad 47, the height of the support plate 46 is adjusted by the hydraulic cylinder 44, and the concave-convex roller is driven to descend. When the end of the concave-convex roller contacts the support wheel 611 on the stabilizing mechanism 6, continuing to adjust the height will cause the support wheel 611 to drive the vertical rod 609 to descend through the mounting plate 610, and the vertical rod 609 will drive the rack rod 6 when it descends. 03 descends, the rack rod 603 will drive the gear 604 to rotate, and the two gears 604 rotate in opposite directions. When the gear 604 rotates, it will drive the clamping rod 606 to move through the extension handle 605, and the bending part of the clamping rod 606 is connected to the outer shell plate 602 through the connecting rod 607. Therefore, when the clamping rod 606 moves, it will rotate relative to the end of the extension handle 605, and the end of the clamping rod 606 will drive the clamping wheel 614 to approach the end of the concave-convex roller until the clamping wheel 614 clamps the outer wall of the end of the concave-convex roller, thereby ensuring the stability of the end of the concave-convex roller.

[0043] The utility model has a simple and reasonable structure, is quick and convenient to use, can simply transport the concave convex roller, and can also make the concave convex roller be raised and lowered on the arc pad 47, which is convenient for early lifting and subsequent transportation. At the same time, the stabilizing mechanism 6 arranged on the base frame 1 can automatically clamp the end of the concave convex roller according to the adjustment of the height of the concave convex roller to ensure the stability of the concave convex roller during transportation. The concave convex roller has a low center of gravity when clamped by the stabilizing mechanism 6. The low center is used to cooperate with the stable clamping of the end to greatly improve the stability of the concave convex roller during transportation. In the later stage, when removing the concave convex roller, it is only necessary to lift the support plate 46. The adjustment is convenient and suitable for popularization and use.
