Description

Technical Field

[0001] The utility model relates to the technical field of roller supports, in particular to a vertical roller support platform. Background Art

[0002] Rollers are the main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. Rollers are mainly composed of three parts: roll body, roll neck and shaft head. The roll body is the middle part of the roll that actually participates in rolling metal. Rollers are heavy and should not be placed horizontally, otherwise they will cause greater wear on the bearings.

[0003] Through patent search, it was found that a Chinese patent with publication number CN216000193U is a vertical support device for a roller. The device has the characteristics of being convenient for vertically supporting and fixing roller bodies of different diameters and heights during roller body processing, and convenient for driving the roller body to rotate while vertically supporting and fixing, thereby improving the processing efficiency of the roller body after vertical support and fixing.

[0004] However, in the actual process, there are the following problems that affect the user's support of the roller: since the mass of the roller is generally heavy, a large driving force is required to drive the roller. In the above device, the second rotating shaft is driven to rotate by a motor. The torque of the motor when it starts to drive the second rotating shaft to rotate is large. During rotation, the initial driving force is insufficient, which may easily lead to tooth breakage, thereby affecting the subsequent processing of the roller. Utility Model Content

[0027] The utility model is further described below in conjunction with embodiments.

[0028] Example

[0029] A vertical roller support platform of this embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a base 1, a supporting leg 2 is fixedly installed at the bottom of the base 1, an annular groove 3 is provided at the upper end of the base 1, a circular hole 4 is provided at the axis of the annular groove 3, a first turntable 5 is plugged into the circular hole 4, a second turntable 6 is fixedly installed on the top of the first turntable 5, the second turntable 6 is fitted with the annular groove 3, a motor 9 is fixedly installed at the edge of the bottom of the base 1, the output end of the motor 9 extends to the bottom of the base 1 and a rotating mechanism is fixedly installed, a fixing block 18 is distributed in an annular shape on the top of the second turntable 6, the fixing block 18 is connected to the supporting mechanism through a pin, the first turntable 5 will reciprocate in the annular groove 3, which can increase the initial driving force of the motor 9 to drive the roller to prevent the roller from rotating due to insufficient initial driving force.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the rotating mechanism includes a first plug-in block 7 and a second plug-in block 8 which are sequentially arranged at the bottom of the base 1. The central axes of the first plug-in block 7 and the second plug-in block 8 are on the same straight line. A worm 10 is fixedly installed at the output end of the motor 9. The left and right ends of the worm 10 are both provided with helical teeth 11, and the thread directions of the two helical teeth 11 are arranged in opposite directions. The worm 10 is threadedly connected to the first plug-in block 7. The worm 10 passes through the first plug-in block 7 and is rotatably connected to the second plug-in block 8. When the worm 10 and the first plug-in block 7 and the second plug-in block 8 are meshed, they are in linear contact rather than point contact, so that when the motor 9 drives the roller to rotate, the transmission ratio is larger and the structure is more compact.

[0031] like Figure 3 and Figure 5 As shown, the two helical teeth 11 are both threadedly connected with a movable block 12, and a first fixed shaft 13 is fixed at the bottom of the movable block 12. The movable block 12 is rotatably connected with a movable plate 16 through the first fixed shaft 13. A sleeve 15 is provided at one end of the movable plate 16 away from the first fixed shaft 13. A second fixed shaft 14 is symmetrically provided at the bottom of the first turntable 5, and the sleeve 15 is sleeved with the second fixed shaft 14. The worm 10 rotates in the first plug-in block 7, and the worm 10 drives the helical teeth 11 to rotate, and the helical teeth 11 drive the movable block 12. Since the central axes of the first plug-in block 7 and the second plug-in block 8 are on the same straight line, the worm 10 will drive the helical teeth 11 to make a linear reciprocating motion between the first plug-in block 7 and the second plug-in block 8. Under the linear motion of the movable plate 16 driven by the helical teeth 11, since the first turntable 5 and the movable plate 16 are rotationally connected, the first turntable 5 will reciprocate in the annular groove 3, so that the motor 9 has a greater driving force when driving the roller to rotate, thereby preventing the phenomenon of tooth collapse.

[0032] like Figure 1 , Figure 3 and Figure 4As shown, the supporting mechanism includes a plug-in plate 19 plugged into a fixed block 18, a limit rod 20 is fixedly installed on the top of the plug-in plate 19, the end of the limit rod 20 away from the plug-in plate 19 is rotatably connected to a connecting block 22, a curved plate 21 is fixedly installed on the connecting block 22, and the curved plate 21 is fitted with the roller, and the limit rod 20 supports the curved plate 21, which can make the roller more stable and prevent it from tipping over.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, a hanging ring 23 is fixedly installed on the left part of the curved plate 21, and a hook 24 is fixedly installed on the right part of the curved plate 21. The hanging ring 23 and the hook 24 are clamped together. When the roller is placed vertically, by rotating the limit rod 20, the limit rod 20 drives the plug-in plate 19 to rotate on the fixed block 18, and then the curved plate 21 is rotated to make the curved plate 21 fit with the roller, and the hanging ring 23 and the hook 24 are clamped together, so that when the roller is placed vertically, the roller is supported more stably.

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, a fixed disk 17 is fixedly installed at the axis center of the top of the second turntable 6, and the roller is placed on the fixed disk 17. The first turntable 5 is driven by the motor 9, and the first turntable 5 drives the second turntable 6 to rotate in the annular groove. A greater driving force is provided to the second turntable 6 through the rotating mechanism to prevent tooth breakage when the motor 9 drives the roller to rotate.

[0035] like Figure 1 As shown, a loading block 25 is sleeved on the limiting rod 20. When the surface of the roller is dirty, the external water pipe is clamped on the loading block 25, so as to facilitate the cleaning of the surface of the roller.

[0036] When in use, the roller is first placed on the fixed plate 17, and the limit rod 20 is rotated, which drives the plug-in plate 19 to rotate on the fixed block 18, and then the curved plate 21 is rotated to make the curved plate 21 fit the roller, so that when the roller is placed vertically, the roller is more firmly supported to prevent the roller from tipping over.

[0037] After the lamination is completed, the motor 9 is started, and the motor 9 drives the worm 10. Since the worm 10 and the first plug-in block 7 and the second plug-in block 8 are in linear contact when meshing, rather than point contact, when the motor 9 drives the roller to rotate, the transmission ratio is larger and the structure is more compact. The worm 10 rotates in the first plug-in block 7, and the worm 10 drives the helical teeth 11 to rotate, and the helical teeth 11 drive the movable block 12. Since the central axes of the first plug-in block 7 and the second plug-in block 8 are on the same straight line, the worm 10 will drive the helical teeth 11 to make a linear reciprocating motion between the first plug-in block 7 and the second plug-in block 8. Under the linear motion of the movable plate 16 driven by the helical teeth 11, since the first turntable 5 and the movable plate 16 are rotationally connected, the first turntable 5 will reciprocate in the annular groove 3, thereby increasing the initial driving force of the motor 9 to drive the roller, and preventing the roller from being easily broken due to insufficient initial driving force when rotating, so as to avoid affecting the subsequent processing of the roller.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
