A scratch-resistant side vertical roller used in steel rolling production lines

Abstract

This utility model relates to an anti-scratch side vertical roller used in a steel rolling production line, including a base, a first connecting seat fixedly mounted on the base, a water cooling device fixedly mounted on the first connecting seat, and a second connecting seat fixedly mounted on the water cooling device. The first connecting seat, the second connecting seat, and the water cooling device are all hollow structures. The central shaft of the side vertical roller passes through the first connecting seat, the water cooling device, and the second connecting seat, and is fixedly connected to the inner ring of a bearing mounted on the first and second connecting seats. A first gap exists between the side wall of the central shaft and the inner wall of the water cooling device. Since the oil tank and the gap are connected by a straight pipe, as long as the oil level in the oil tank is above the horizontal plane where the second bearing is located, the lubricating oil level in the gap will also necessarily be above the second bearing. The oil level in the oil tank can be determined by observing the level gauge, which is connected to the oil tank. This design facilitates observation of the lubricating oil condition, allowing for timely replenishment of lubricating oil and ensuring the normal operation of the side vertical roller.

Description

Technical Field

[0001] This utility model relates to anti-scratch side rollers in steel rolling production lines, specifically to an anti-scratch side roller used in steel rolling production lines. Background Technology

[0002] During the rolling process, steel (hereinafter referred to as "rolled pieces") is mainly transferred or transported via roller conveyors. During the transfer of rolled pieces, there is a relative frictional movement between the side panels of the roller conveyor and the rolled pieces. To avoid scratching the rolled pieces, side vertical rollers are installed every 1.5m along the conveyor roller conveyor. The rolled pieces drive the side vertical rollers to rotate, ensuring the normal transmission of the rolled pieces.

[0003] Currently, the lubrication method for side vertical rollers is such as the roller conveyor side vertical roller disclosed by our company in patent CN 222241942 U. It addresses the problems of high oil consumption and serious ground pollution caused by the use of oil-air lubrication for the side vertical roller structure. The design proposes a method where the vertical roller is fixed on a shaft, and the shaft and oil tank rotate together. The oil tank contains oil, which is used to lubricate the bearings, thereby overcoming the problems of high oil consumption and leakage.

[0004] However, in this solution, it is impossible to know how much lubricating oil is in the oil drum. When the oil drum is low on oil, it cannot be replenished in time. Moreover, oil replenishment requires removing the plugging screw, lifting the pressure cap and waterproof cover from the oil drum, and then replenishing the oil. The oil replenishment work is cumbersome.

[0005] Based on this, this utility model was designed. Summary of the Invention

[0006] To address the aforementioned issues, this invention proposes an anti-scratch side vertical roller for use in steel rolling production lines. Since the oil tank and the interval are connected by a straight pipe, as long as the oil level in the oil tank is above the horizontal plane where the second bearing is located, the oil level in the interval will also be above the second bearing. The oil level in the oil tank can be determined by observing the level gauge, which is connected to the oil tank. This solution facilitates the observation of the lubricating oil condition, allowing for timely replenishment of lubricating oil and ensuring the normal operation of the side vertical roller.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a scratch-resistant side vertical roller applied in a steel rolling production line, comprising a base, a first connecting seat fixedly installed on the base, a water cooling device fixedly installed on the first connecting seat, and a second connecting seat fixedly installed on the water cooling device. The first connecting seat, the second connecting seat, and the water cooling device are all hollow structures. The central shaft of the side vertical roller passes through the first connecting seat, the water cooling device, and the second connecting seat and is fixedly connected to the inner ring of the bearing installed on the first connecting seat and the second connecting seat. There is a first gap between the side wall of the central shaft and the inner wall of the water cooling device.

[0008] Based on the above scheme, as a preferred embodiment, the lower end of the first connecting seat is sealed to the base, the lower end face of the first bearing whose outer ring is fixedly mounted on the first connecting seat has a second gap with the base, and the inner ring of the first bearing is fixedly connected to the central shaft.

[0009] Based on the above scheme, as a preferred embodiment, the side wall of the second connecting seat has an oil injection hole, the height of which is higher than the height of the second bearing whose outer ring is fixed on the second connecting seat, and the inner ring of the second bearing is fixedly connected to the central shaft.

[0010] Based on the above scheme, as a preferred option, there is a third gap between the second connecting seat and the central shaft. The oil filling hole is connected to the oil outlet at the bottom of the oil tank through a straight pipe. The upper end of the oil tank is open and is detachably covered. A liquid level gauge is fixedly installed on the side wall of the oil tank. The oil inlet at the bottom of the liquid level gauge is connected to the area inside the oil tank, and the connection is located at the bottom of the oil tank, forming a U-shaped communicating vessel structure.

[0011] Based on the above scheme, as a preferred option, the upper end of the second connecting seat is fixedly installed with a bearing cover by bolts, and the central shaft passes through the bearing cover and rotates with the bearing cover.

[0012] Based on the above scheme, as a preferred embodiment, the water cooling device includes a first ring plate and a second ring plate, with a fourth gap between the first ring plate and the second ring plate. The first gap is located between the second ring plate and the central shaft. The opposing walls of the first ring plate and the second ring plate each have several annular baffles arranged in an alternating pattern. The upper end of the first ring plate has a water inlet, and the lower end of the second ring plate has a water outlet.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Since the oil tank and the interval are connected by a straight pipe, as long as the liquid level in the oil tank is above the horizontal plane where the second bearing is located, the liquid level in the interval will also be above the second bearing. The liquid level in the oil tank can be judged by observing the liquid level gauge that is connected to the oil tank. This solution facilitates the observation of the lubricating oil condition, so as to add lubricating oil in time and ensure the normal operation of the side vertical roller.

[0014] This method is very convenient; simply open the fuel tank cap to refuel.

[0015] This solution utilizes the first and second ring plates arranged at intervals to form a water-cooling structure, which also forms the outer protection of the central shaft. By passing water through and circulating it in the fourth interval between the first and second ring plates, the lubricating oil between the second ring plate and the central shaft is cooled, reducing lubrication input and maintenance costs.

[0016] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0017] The present invention will be further described below through embodiments, but the scope of the present invention is not limited thereto.

[0018] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0019] like Figure 1 As shown, an anti-scratch side roller used in a steel rolling production line includes a base 1, a first connecting seat 2 fixedly installed on the base, a water cooling device fixedly installed on the first connecting seat, and a second connecting seat 3 fixedly installed on the water cooling device. The first connecting seat, the second connecting seat, and the water cooling device are all hollow structures. The central shaft 5 of the side roller 4 passes through the first connecting seat, the water cooling device, and the second connecting seat and is fixedly connected to the inner ring of the bearing installed on the first connecting seat and the second connecting seat. There is a first gap 6 between the side wall of the central shaft and the inner wall of the water cooling device.

[0020] The lower end of the first connecting seat is sealed to the base. The lower end face of the first bearing 7, whose outer ring is fixedly mounted on the first connecting seat, has a second gap 8 between it and the base to avoid interfering with the rotation of the inner ring of the bearing. The inner ring of the first bearing is fixedly connected to the central shaft. The first gap, the second gap, and the third gap (described below) are all filled with lubricating oil.

[0021] To facilitate the injection of lubricating oil, the side wall of the second connecting seat has an oil injection hole 9. The height of the oil injection hole is higher than the height of the second bearing 10 whose outer ring is fixed on the second connecting seat. The inner ring of the second bearing is fixedly connected to the central shaft.

[0022] To ensure the amount of lubricating oil in the intervals (the first interval, the second interval, and the third interval 18 between the second connecting seat and the central shaft) and to add lubricating oil in a timely manner, the oil filling hole is connected to the oil outlet 13 at the bottom of the oil tank 12 through a straight pipe 11. The upper end of the oil tank is open and is detachably equipped with a top cover 14 (the top cover is threaded to the upper end of the oil tank). A liquid level gauge 15 (a transparent tube with graduations on the outer wall and an oil inlet at the bottom for introducing oil into the tube, such as the liquid level gauge---YW0-150 / 160 / 200 / 250 / 300 / 350 / 400 / 450 / 500 / 550 / 600 / 800 produced by Wenzhou Liyin Plastic & Electrical Factory) is fixedly installed on the side wall of the oil tank. The oil inlet 16 at the bottom of the liquid level gauge is connected to the area inside the oil tank, and the connection is located at the bottom of the oil tank, forming a U-shaped communicating vessel structure.

[0023] The upper end of the second connecting seat is fixedly installed with a bearing cover 17 by bolts, and the central shaft passes through the bearing cover and rotates with the bearing cover.

[0024] The water-cooling device includes a first ring plate 19 and a second ring plate 20. A fourth interval 21 is provided between the first and second ring plates. The first interval is located between the second ring plate and the central axis. Several annular baffles 22 are arranged alternately on the opposite walls of the first and second ring plates. The upper end of the first ring plate has a water inlet 23, and the lower end of the second ring plate has a water outlet 24. The alternate arrangement of the baffles prolongs the flow time of the circulating water in the fourth interval, thereby improving the heat exchange effect. In the attached drawings of this scheme, only four baffles are shown (two for the first ring plate and two for the second ring plate). In actual installation, the number depends on the specific height of the first and second ring plates. The thickness of the baffles is 3-4 mm of steel plate, and the vertical spacing is 2-3 cm.

[0025] The outlet of the water cooling device can be connected to the intermediate water tank for natural cooling of the water. The intermediate water tank can be connected to the inlet by a pump to achieve water circulation, which can save water. The intermediate water tank is open.

[0026] In this design, since the oil tank and the interval are connected by a straight pipe, as long as the oil level in the tank is above the horizontal plane where the second bearing is located, the oil level in the interval will also be above the second bearing. The oil level in the tank can be determined by observing the level gauge, which is connected to the oil tank. Compared to the roller conveyor side vertical roller disclosed in our patent CN 222241942 U, this design facilitates observation of the lubricating oil level, allowing for timely lubrication and ensuring the normal operation of the side vertical roller. Furthermore, this design only requires opening the oil tank cap to add lubricating oil, making operation convenient.

[0027] This solution utilizes the first and second ring plates arranged at intervals to form a water-cooling structure, while also forming an outer protection for the central shaft. By introducing and circulating water in the fourth interval between the first and second ring plates, the lubricating oil between the second ring plate and the central shaft is cooled. Compared with the roller conveyor side vertical roller disclosed in our patent CN 222241942 U, this solution reduces lubrication investment and maintenance costs.

[0028] It should be noted that the embodiments described above are only for explaining the present invention and do not constitute any limitation on the present invention. The present invention has been described with reference to typical embodiments, but it should be understood that the words used therein are descriptive and explanatory terms, not limiting terms. Modifications can be made to the present invention within the scope of the claims, and revisions can be made to the present invention without departing from the scope and spirit of the present invention. Although the present invention described herein relates to specific methods, materials, and embodiments, it does not mean that the present invention is limited to the specific examples disclosed herein; on the contrary, the present invention can be extended to all other methods and applications with the same function.
