Description

Technical Field

[0001] This utility model relates to a fan-shaped section disc roller device for a slab continuous casting machine, belonging to the technical field of maintenance of fan-shaped section equipment in continuous casting machines in the metallurgical industry. Background Technology

[0002] The sector section is one of the core pieces of equipment in a slab continuous casting machine. It pulls the slab with a liquid core from the crystallizer and into the sector section, where it is supported and straightened by the sector section rollers. The condition of the sector section rollers directly affects the quality of the slab produced by the continuous casting machine, and abnormal condition of the sector section rollers is the most common and persistent hidden danger in the sector section. If the rollers seize up during production, scratches will appear on the surface of the slab.

[0003] Currently, to deal with the problem of roller seizure during continuous casting machine production, it is necessary to stop the machine and replace the seized sector section of the roller. After the sector section roller is repaired, the roller's operating status is generally checked by manual roller rotation, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide a fan-shaped section roller device for a slab continuous casting machine, which can quickly check the rotation status of the fan-shaped section rollers, replace manual roller operation, improve the stability of the fan-shaped section after it is put into operation, and solve the above-mentioned problems in the background art.

[0005] The technical solution of this utility model is:

[0006] A slab continuous casting machine fan-shaped section disc roller device includes driven rollers, drive rollers, arc rings, lifting devices, sliders, slide rails, and a rotating support. The rotating support is rotatably connected to the fan-shaped section maintenance platform. The slide rails are fixed on the rotating support, and the sliders are slidably connected to the slide rails. The arc rings are suspended on the sliders by the lifting devices. The size of the arc rings is matched with the fan-shaped section rollers. The driven rollers are rotatably connected to both ends of the arc rings, and the drive rollers are rotatably connected to the middle of the arc rings. The two driven rollers and one drive roller are all located on the inner arc surface of the arc rings. The two driven rollers and one drive roller form an arc-shaped disc roller structure that has three-point contact with the fan-shaped section rollers.

[0007] The arc-shaped ring is provided with support plates radially at both ends.

[0008] Both ends of the arc-shaped ring are provided with shock-absorbing rubber strips under the radial support plates.

[0009] The drive roller is connected to the motor reducer via a coupling.

[0010] The rotating bracket is rotatably connected to the sector section maintenance platform via bearings.

[0011] The beneficial effects of this utility model are: after the fan-shaped section rollers are installed, the rotation status of the fan-shaped section rollers can be quickly confirmed by the disc roller device, ensuring the maintenance quality of the fan-shaped section, improving the work efficiency of the fan-shaped section maintenance, and enhancing the stability of the fan-shaped section after it is put into operation.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and examples.

[0016] See attached document Figure 1 , 2 A slab continuous casting machine fan-shaped section disc roller device includes a driven roller 1, a drive roller 2, an arc ring 8, a lifting device 10, a slider 11, a slide rail 12, and a rotating support 13. The rotating support 13 is rotatably connected to the fan-shaped section maintenance platform. The slide rail 12 is fixed on the rotating support 13. The slider 11 is slidably connected to the slide rail 12. The arc ring 8 is suspended on the slider 11 by the lifting device 10. The size of the arc ring 8 matches that of the fan-shaped section roller 15. The driven roller 1 is rotatably connected to both ends of the arc ring 8. The drive roller 2 is rotatably connected to the middle of the arc ring 8. The two driven rollers 1 and the drive roller 2 are all located on the inner arc surface of the arc ring 8. The two driven rollers 1 and the drive roller 2 form an arc-shaped disc roller structure that contacts the fan-shaped section roller 15 at three points.

[0017] In this embodiment, the slab continuous casting machine's sector-shaped section roller device includes a driven roller 1, a drive roller 2, a coupling 3, a motor reducer 4, a bearing housing 5, a shock-absorbing rubber strip 6, a support plate 7, an arc-shaped ring 8, a lifting ring 9, a lifting device 10, a slider 11, a slide rail 12, a rotating bracket 13, a rotating bearing 14, a sector-shaped section roller 15, and a sector-shaped section frame 16, wherein:

[0018] The rotating bracket 13 is set on the fan-shaped section maintenance platform, and the rotating bearing 14 is installed at the bottom of the rotating bracket 13, so that the rotating bracket 13 can rotate freely. One end of the slide rail 12 is vertically connected to the top of the rotating bracket 13. The slider 11 is set on the slide rail 12 and is connected to the lifting device 10. The lifting device 10 is a chain hoist. The lifting ring 9 is set on the top of the outer arc of the arc ring 8 and connected to the lifting device 10. The arc ring 8 can slide left and right along the slide rail 12 through the slider 11, and can also rotate 360° through the rotating bracket 13 and the rotating bearing 14.

[0019] The drive roller 2 has a spindle made of 45# steel with a diameter of 200mm. The roller sleeve is made of rubber with an outer diameter of 300mm and a length of 300mm. The drive roller 2 is mounted on the top of the inner arc side of the arc ring 8 using a bearing seat 5 and is connected to the motor reducer 4 via a coupling 3. There are two driven rollers 1, which are made of nylon and are mounted at both ends of the bottom of the inner arc side of the arc ring 8 using a bearing seat 5.
