Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron and steel metallurgy, and specifically to a sponge roller lubrication device suitable for annular tracks. Background Technology
[0002] The annular cooler (hereinafter referred to as the annular cooler) is a key piece of equipment in the metallurgical industry for cooling high-temperature sintered ore. Currently, the mainstream annular cooler adopts a trolley-rotor body + support roller structure. This means that an annular track is installed below the outer and inner ring plates of the entire trolley-rotor body, and the entire unit is placed on the inner and outer ring support rollers. A drive device rotates the cooler on the support rollers. To reduce the friction between the annular track and the support rollers, minimize wear on spare parts, and thus reduce the load on the annular cooler, lubrication is required. The current lubrication method involves installing an oil box under the support rollers, adding thin oil to the box until it covers the lower edge of the support rollers. As the support rollers rotate, they carry the thin oil to the track surface for lubrication. However, this method often results in grease contamination and leakage due to dust, oil leakage from the support rollers, and exposure to rain, requiring frequent cleaning of the oil box and maintaining a clean work site, increasing labor intensity and safety hazards. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings and defects of the existing technology by providing a sponge roller lubrication device suitable for annular tracks. This lubrication device can be used for the lubrication of the annular track and support rollers of a sintering ring cooler. Since this lubrication device is installed directly below the trolley rotating body, the trolley rotating body can completely cover the device, preventing rainwater from entering the oil box, reducing grease leakage and pollution, improving the on-site environment, eliminating the safety hazard of oil leakage, and reducing the labor intensity of workers.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a sponge roller lubrication device suitable for a circular track, comprising a main support bracket, a side limiting block welded to one side of the top of the main support bracket, and a limiting bolt group installed on the other side of the top of the main support bracket, an oil box installed between the side limiting block and the limiting bolt group, the oil box being located on the top of the main support bracket, and a sponge roller being provided in the inner cavity of the oil box.
[0005] Furthermore, a gasket is installed between the oil box and the main support bracket.
[0006] Furthermore, the main support bracket includes two vertical angle steels, both of which are welded to the water trough steel plate. Horizontal angle steels are welded to the upper ends of both vertical angle steels, and diagonal reinforcing plates are welded between the two horizontal angle steels and the two vertical angle steels. A horizontal reinforcing plate is also welded between the two horizontal angle steels.
[0007] Furthermore, symmetrical U-shaped slots are provided at both ends of the oil box.
[0008] Furthermore, the sponge roller includes a central roller shaft, the outer wall of which is fitted with an inner sleeve, and the outer wall of the inner sleeve is adhered with a sponge body.
[0009] After adopting the above technical solution, the beneficial effects of this utility model are as follows: This lubrication device can be applied to the lubrication of the annular track and support roller of the sintering ring cooler. Since this lubrication device is installed directly below the trolley rotating body, the trolley rotating body can completely cover this device, preventing rainwater from entering the oil box, reducing grease leakage and pollution, which not only improves the on-site environment and eliminates the safety hazard of oil leakage, but also reduces the labor intensity of the workers.

Inner sleeve. Detailed Implementation
[0025] See Figures 1-12 As shown, the technical solution adopted in this specific embodiment is as follows: it includes a main support bracket 1, a side limiting block 2 is welded to one side of the top of the main support bracket 1, and a limiting bolt group 6 is installed on the other side of the top of the main support bracket 1. An oil box 3 is installed between the side limiting block 2 and the limiting bolt group 6. The oil box 3 is set on the top of the main support bracket 1, and a sponge roller 4 is provided in the inner cavity of the oil box 3.
[0026] More specifically, a gasket 5 is installed between the oil box 3 and the main support bracket 1. The gasket 5 prevents the oil box 3 from directly contacting the main support bracket 1, which increases the installation stability of the oil box 3 and the service life of both the oil box 3 and the main support bracket 1. At the same time, the gasket can also be used to adjust the installation height of the oil box to ensure that there is a compression of about 5mm between the sponge roller and the track.
[0027] More specifically, the main support bracket 1 includes two vertical angle steels 11, both of which are welded to the water tank steel plate. Horizontal angle steels 12 are welded to the upper ends of both vertical angle steels 11, and diagonal reinforcing plates 13 are welded between the two horizontal angle steels 12 and the two vertical angle steels 11. A horizontal reinforcing plate 14 is welded between the two horizontal angle steels 12. The main support bracket 1 is welded to the water tank steel plate via the vertical angle steels 11, while the oil box 3 is placed on the horizontal angle steels 12. The diagonal reinforcing plates 13 enhance the connection stability between the horizontal angle steels 12 and the vertical angle steels 11, and the horizontal reinforcing plates 14 enhance the stability between the two diagonal reinforcing plates 13.
[0028] More specifically, the oil box 3 has symmetrical U-shaped slots 301 at both ends. The U-shaped slots 301 can be used to place the middle roller 41.
[0029] More specifically, the sponge roller 4 includes a central roller 41, the outer wall of which is fitted with an inner sleeve 43, and the outer wall of the inner sleeve 43 is attached with a sponge body 42.
[0030] The working principle of this utility model is as follows: During installation and use, the operator can adjust the height of the main support bracket 1 and weld it to the steel plate of the water tank, placing the main support bracket 1 below the annular track. Then, the sponge roller 4 is installed on the U-shaped slot 301 of the oil box 3, and the oil box 3 with the sponge roller 4 installed is placed on the horizontal angle steel 12 of the bracket. The oil box 3 is fixed by the side limiting block 2 and the limiting bolt group 6. During fixing, simply rotate the bolts on the limiting bolt group 6, and the oil box 3 is compressed by the bolts. With the cooperation of the side limiting block 2, the oil box 3 can be fixed. The oil box 3 is placed directly below the annular track, and the sponge roller 4 is in contact with the annular track. It should be ensured that the sponge body 42 has a compression of about 5mm. The contact friction between the sponge body 42 and the annular track drives the sponge roller 4 to rotate. Add sufficient lubricating oil to the oil box 3 to immerse the bottom of the sponge 42. Utilizing the oil-absorbing properties of the sponge 42, the lubricating oil is carried to the annular track surface for lubrication as the sponge roller 4 rotates. (See [reference needed]). Figure 13 As shown.
[0031] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
