Description
Technical Field
[0001] This utility model relates to the field of conveying equipment technology, and in particular to a conveying equipment for rolling special steel. Background Technology
[0002] Special steel, also known as high-quality special steel, is a type of steel with unique chemical composition and produced using special processes. It possesses excellent properties such as high strength, high toughness, high temperature resistance, and corrosion resistance, and is widely used in high-end fields such as aerospace, energy and power, and machinery manufacturing. Special steel rolling conveying equipment is an indispensable key piece of equipment in the production process of special steel. It is defined as: in the special steel rolling process, it is a mechanical device used to efficiently and stably transfer heated steel billets, semi-finished products during rolling, and finished steel products between different stages such as heating furnaces, rolling mills, cooling devices, shearing equipment, and collection areas, according to production process requirements.
[0003] Currently, the conveying equipment for special steel rolling mills faces significant limitations in practical applications. Due to the diverse forms of special steel products, including steel plates, columns, pipes, and sections of steel in various specifications, each product exhibits substantial differences in shape, size, and weight. This presents numerous challenges in selecting and configuring conveying equipment. For example, steel plates require a large support area during conveying to prevent deformation, typically employing wide-width roller conveyors; while long, strip-shaped steel materials such as columns are better suited to chain conveyors or a combination of roller and chain conveyors. However, most existing conveying equipment is specialized equipment designed for a single product form, lacking versatility. When production shifts from steel plate rolling to steel column rolling, large-scale modifications or equipment replacements of the entire conveying system are often necessary, consuming significant time and manpower and substantially increasing production costs. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] Therefore, one objective of this utility model is to provide a special steel rolling and conveying equipment to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0006] To achieve the above objectives, one embodiment of this utility model provides a special steel rolling conveying device, including a base frame. Two corresponding front and rear frames are fixedly connected to the top of the base frame. A plurality of linearly arrayed rollers are rotatably connected between the two frames via bearings. An L-shaped bracket is fixedly installed on the top of each frame via bolts. An electric push rod is fixedly connected to one side of each L-shaped bracket. A movable plate is fixedly connected to the output end of the electric push rod. Two movable plates are located between the two frames. A plurality of linearly arrayed through holes are opened through one side of each movable plate. The center of each through hole coincides with the axis of the roller. A sleeve is rotatably connected to the inner wall of each through hole via bearings. The sleeve is slidably connected to the roller. A frustum-shaped limiting sleeve is fixedly connected to one end of the sleeve, and the frustum-shaped limiting sleeve is slidably connected to the roller.
[0007] Preferably, in any of the above schemes, a cover plate is fixedly connected to the inner side of both frames, and a plurality of linear array partition plates are fixedly connected between the two cover plates, with the plurality of partition plates and a plurality of rollers arranged alternately.
[0008] Preferably, one side of each of the above-mentioned schemes has a plurality of linearly arrayed clearance slots, and the movable plate is slidably connected to the partition plate through the clearance slots.
[0009] Preferably, in any of the above embodiments, two symmetrically arranged guide rods are fixedly connected to the side of the movable plate near the electric push rod, the electric push rod is located between the two guide rods, and both guide rods are slidably connected to the movable plate.
[0010] Preferably, in any of the above solutions, the inner wall of the frustum limiting sleeve is fixedly connected to two symmetrically arranged limiting plates, and the outer surface of the roller is provided with two sets of left and right corresponding limiting grooves, and the limiting plates are slidably connected to the roller through the limiting grooves.
[0011] Preferably, the bottom of the base frame is provided with height-adjustable feet, which are connected to the base frame via threads.
[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0013] 1. When switching to convey different specifications of steel, the electric push rod pushes the moving plate to slide along the guide rod, causing the sleeve and the frustum limit sleeve to move on the roller until the ends of the two frustum limit sleeves away from the moving plate are in contact. The two spliced frustum limit sleeves can then convey the steel column. Moreover, the frustum limit sleeves can rotate with the roller without affecting the conveying efficiency. The electric push rod pushes the moving plate to slide along the guide rod until the two frustum limit sleeves are far apart, at which point the steel plate can be placed on top of the roller for conveying. The frustum limit sleeves will not interfere with the rotation of the roller. This design allows the same equipment to quickly adapt to the conveying needs of various special steel products such as steel plates and steel columns. There is no need to replace the core components; only the spacing of the frustum limit sleeves needs to be adjusted to complete the conversion, which significantly improves the equipment utilization rate.
[0014] 2. When the steel plate is placed above the roller for conveying, the electric push rod can be turned on to push the moving plate to move, thereby driving the two truncated cone limit sleeves to approach the steel plate until the ends of the two truncated cone limit sleeves away from the moving plate are in contact with the left and right sides of the steel plate. This can limit the conveying of the steel plate and prevent the steel plate from deviating during conveying. Attached Figure Description

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.
[0022] like Figures 1 to 5As shown, a special steel rolling conveying device includes a base frame 1. Two corresponding front and rear frames 2 are fixedly connected to the top of the base frame 1. Several linear array rollers 3 are rotatably connected between the two frames 2 via bearings. An L-shaped bracket 4 is fixedly installed on the top of each frame 2 by bolts. An electric push rod 5 is fixedly connected to one side of each L-shaped bracket 4. A movable plate 6 is fixedly connected to the output end of the electric push rod 5. Both movable plates 6 are located between the two frames 2. Several linear array through holes 7 are opened through one side of each movable plate 6. The center of the through holes 7 coincides with the axis of the roller 3. A sleeve 8 is rotatably connected to the inner wall of each through hole 7 via bearings. The sleeve 8 is slidably connected to the roller 3. A frustum limiting sleeve 9 is fixedly connected to one end of the sleeve 8. The frustum limiting sleeve 9 is slidably connected to the roller 3.
[0023] As an optional technical solution of this utility model, a cover plate 10 is fixedly connected to the inner side of both frames 2, and a number of linear array partition plates 11 are fixedly connected between the two cover plates 10. The partition plates 11 and the rollers 3 are staggered. The cooperative design of the cover plate 10 and the partition plate 11 effectively blocks the oxide scale and coolant splashes generated during the rolling process, protecting the internal transmission components. At the same time, the staggered arrangement of the partition plates 11 and the rollers 3 ensures the stability of steel conveying.
[0024] As an optional technical solution of this utility model, a plurality of linear array of clearance slots 12 are provided through one side of each movable plate 6. The movable plate 6 is slidably connected to the partition plate 11 through the clearance slots 12. The sliding connection between the clearance slots 12 and the partition plate 11 ensures that the adjustment movement of the movable plate 6 is unimpeded, ensuring that the position adjustment of the frustum limit sleeve 9 is smooth, while maintaining the overall structural rigidity of the equipment.
[0025] As an optional technical solution of this utility model, two symmetrically arranged guide rods 13 are fixedly connected to the side of the movable plate 6 near the electric push rod 5. The electric push rod 5 is located between the two guide rods 13. Both guide rods 13 are slidably connected to the movable plate 6. The symmetrical arrangement of the guide rods 13 ensures that the movable plate 6 maintains linear motion under the drive of the electric push rod 5, prevents skew and jamming, and improves the accuracy and reliability of position adjustment.
[0026] As an optional technical solution of this utility model, the inner wall of the frustum limiting sleeve 9 is fixedly connected with two symmetrically arranged limiting plates 14, and the outer surface of the roller 3 is provided with two sets of left and right corresponding limiting grooves 15. The limiting plates 14 are slidably connected to the roller 3 through the limiting grooves 15. The sliding cooperation between the limiting plates 14 and the limiting grooves 15 allows the frustum limiting sleeve 9 to move and adjust axially, while restricting its circumferential rotation, ensuring that the limiting function is stable and reducing the wear of the sleeve 8.
[0027] As an optional technical solution of this utility model, the bottom of the base frame 1 is provided with a height adjustment foot 16. The height adjustment foot 16 is connected to the base frame 1 by a thread. The height adjustment foot 16 achieves quick leveling of the base frame 1 through the threaded connection, adapts to the differences in foundation height of different production lines, and ensures the levelness and running stability of the conveyor roller.
[0028] A special steel rolling conveying equipment, the working principle of which is as follows:
[0029] 1): The electric push rod 5 pushes the moving plate 6 to slide along the guide rod 13, which drives the sleeve 8 and the truncated cone limit sleeve 9 to move on the roller 3 until the ends of the two truncated cone limit sleeves 9 away from the moving plate 6 are in contact. Then the two spliced truncated cone limit sleeves 9 can transport the steel column.
[0030] 2): The electric push rod 5 pushes the moving plate 6 to slide along the guide rod 13 until the two truncated cone limit sleeves 9 are far apart, then the steel plate can be placed above the roller 3 for conveying.
[0031] 3): Activate the electric push rod 5 to push the moving plate 6 to move, which in turn drives the two truncated cone limit sleeves 9 to approach the steel plate until the ends of the two truncated cone limit sleeves 9 away from the moving plate 6 are in contact with the left and right sides of the steel plate, which can limit the conveying of the steel plate.
[0032] In summary, this special steel rolling conveying equipment, when switching to convey different specifications of steel, uses an electric push rod 5 to push a moving plate 6 to slide along a guide rod 13, causing the sleeve 8 and the frustum limiting sleeve 9 to move on the roller 3 until the ends of the two frustum limiting sleeves 9 furthest from the moving plate 6 are in contact. The two joined frustum limiting sleeves 9 can then convey the steel column, and the frustum limiting sleeves 9 can rotate with the roller 3 without affecting the conveying efficiency. The electric push rod 5 pushes the moving plate 6 to slide along the guide rod 13 until the two frustum limiting sleeves 9 are far apart, allowing the steel plate to be placed above the roller 3 for conveying. The limiting sleeve 9 will not interfere with the rotation of the roller 3. This design allows the same equipment to quickly adapt to the conveying needs of various special steel products such as steel plates and steel columns. There is no need to replace the core components. Only the spacing of the truncated cone limiting sleeves 9 needs to be adjusted to complete the conversion, which significantly improves the utilization rate of the equipment. When the steel plate is placed above the roller 3 for conveying, the electric push rod 5 can be activated to push the moving plate 6 to move, which in turn drives the two truncated cone limiting sleeves 9 to approach the steel plate until the ends of the two truncated cone limiting sleeves 9 away from the moving plate 6 are in contact with the left and right sides of the steel plate. This can limit the conveying of the steel plate and prevent the steel plate from deviating during conveying.
