Description

Technical Field

[0001] This utility model relates to the technical field of thin slab conveying equipment, specifically a conveying device to prevent thin slabs from getting stuck in steel. Background Technology

[0002] In cold-rolled special steel sheet production lines, intermediate billets are primarily transported via roller conveyor systems. Currently, most mainstream roller conveyor systems employ a grouped centralized drive system. This design has an inherent flaw at the junction of two sets of rollers: insufficient speed matching accuracy between different drive units easily leads to billet misalignment. This is particularly challenging for ultra-thin billets with thicknesses of 0.65–1.0 mm. Without a correction structure, when billet misalignment occurs, the billet edge can easily penetrate the gap, potentially causing a steel jamming accident.

[0003] In addition, the actual contact area between the roller and the rare and precious metal billet is large, and the surface of the billet is easily scratched; moreover, when the billet passes through the junction area of ​​two adjacent rollers, a gradual support transition cannot be achieved, the billet cannot pass smoothly, and the probability of horizontal steel jamming is high; the stress distribution of the billet is uneven, and local stress concentration is easy to occur.

[0004] In addition, when the billet deviates, the existing side baffle device has obvious design defects: the assembly gap between the baffle and the roller body (usually 5-10mm) cannot effectively adapt to the characteristics of thin-gauge materials, which can easily cause the edge of the billet to drill into the gap, thus causing steel jamming accidents.

[0005] Unplanned downtime caused by stuck steel affects production efficiency. Furthermore, stuck steel accidents can also cause scratches on the surface of billets, affecting product qualification rates. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a transport device to prevent thin slabs from getting stuck, which can effectively prevent thin slabs from getting stuck, improve production efficiency, and increase product qualification rate.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A conveying device for preventing steel from getting stuck in thin slabs includes a motor, a gearbox, a roller conveyor, and conveyor rollers. Multiple conveyor rollers are arranged in a row along the conveying direction with parallel axes. Cylindrical protrusions are evenly distributed along the axial direction on the surface of each roller. The cylindrical protrusions of adjacent rollers interlock to ensure that the protrusions correspond to the gap areas of adjacent rollers, forming a continuous conveying trajectory. The gearbox is fixedly connected to the roller conveyor, and the conveyor rollers are hinged to bearing seats, which are fixedly connected to the roller conveyor. The motor is connected to the input shaft of the gearbox, and the output shaft of the gearbox is connected to the conveyor rollers. The motor drives the multiple conveyor rollers to rotate synchronously through the gearbox.

[0009] Furthermore, it also includes baffles, which are disposed on both sides of the conveyor roller and fixed to the roller frame. The baffles are located between the end face of the bearing seat and the cylindrical protruding end face of the conveyor roller.

[0010] Furthermore, the baffle is formed by the baffle body, the support frame and the mounting base being fixed together. The support frame provides rigid support for the baffle body, and the mounting base is fixed to the roller conveyor frame by bolts.

[0011] Furthermore, the baffle body has outward bends at both ends.

[0012] Furthermore, the roller conveyor frame includes a first roller conveyor frame and a second roller conveyor frame, and the bearing housing includes a first bearing housing and a second bearing housing. The first roller conveyor frame and the second roller conveyor frame are disposed on both sides of the conveyor roller. The gearbox is fixedly connected to the first bearing housing on the first roller conveyor frame, and the second bearing housing is fixedly connected to the second roller conveyor frame. Both ends of the conveyor roller are installed on the first bearing housing and the second bearing housing.

[0013] Furthermore, it also includes a motor frame, which is fixed to the civil engineering foundation, and the motor is fixed to the motor frame.

[0014] Furthermore, the roller conveyor frame is fixedly connected to the civil engineering foundation.

[0015] Furthermore, the roller conveyor frame is a box-type frame structure.

[0016] Furthermore, the output shaft of the motor is connected to the input shaft of the gearbox via a first coupling.

[0017] Furthermore, the output shaft of the gearbox is connected to the shaft of the conveyor roller via a second coupling.

[0018] Compared with the prior art, the present invention has at least the following technical effects or advantages:

[0019] 1. This utility model includes a motor, a gearbox, a roller frame, and conveyor rollers. The motor drives multiple conveyor rollers to rotate synchronously through the gearbox, realizing centralized transmission. All components work together to ensure the stable conveying of rare and precious metal slabs and meet the conveying requirements of rare and precious metal slabs of different thicknesses.

[0020] This invention features cylindrical protrusions evenly distributed along the axial direction on the surface of the rollers. The protrusions of adjacent rollers interlock, ensuring that the protrusions correspond to the gaps between adjacent rollers, forming a continuous transmission trajectory with a regularly distributed stepped structure on the surface. The adjacent rollers are arranged in a staggered manner, meaning the steps of adjacent rollers are offset from each other. This not only effectively reduces the actual contact area between the rollers and the rare and precious metal billet, significantly lowering the risk of surface scratches on the billet, but also allows for a gradual support transition when the billet passes through the boundary area between two adjacent rollers, ensuring smooth passage and significantly reducing the probability of horizontal steel jamming. Simultaneously, this structure improves the stress distribution on the billet, avoiding localized stress concentration, thereby enhancing the stability of the rolling process and product quality. This structure ensures that the thin slab is always under the coordinated support of multiple roller surfaces, completely eliminating the phenomenon of the billet drilling into the gaps between adjacent rollers.

[0021] 2. This utility model includes baffles positioned on both sides of the conveyor roller and fixed to the roller frame. The baffles are located between the bearing seat end face and the cylindrical protruding end face of the conveyor roller, maintaining a 5-10mm gap with the roller neck. When the billet deviates, the impact force is entirely borne by the upper part of the fixed side baffles; the unique installation position completely prevents the billet from entering the gap between the roller and the fixed side baffles. The stepped structure of the conveyor roller prevents steel penetration from the roller surface contact angle, while the fixed baffles prevent steel jamming from the side guiding angle; the two work together to form a three-dimensional protection system.

[0022] 3. The roller conveyor frame of this utility model adopts a box-shaped frame structure welded from high-strength steel plates. Its bottom surface is rigidly connected to the civil engineering foundation through anchor bolts to ensure overall stability.

[0023] 4. This utility model's fixed side baffle is welded together from a baffle body, a support frame, and a mounting base. The baffle body is made of high-strength, wear-resistant steel plate to withstand frequent friction and impact from the billet. The support frame is composed of welded steel structure, providing rigid support for the baffle and ensuring it does not deform under lateral forces. The mounting base is fixed to the roller conveyor with bolts, ensuring the horizontal and vertical alignment of the mounting plane to prevent the baffle from skewing and causing the rolled piece to deviate.

[0024] 5. The two ends of the baffle body of this utility model are provided with outward bends to ensure smooth transmission. Attached Figure Description

[0034] like Figure 1 , Figure 2 As shown, a conveying device for preventing thin slabs from jamming steel is installed in the intermediate roller table before and after the reversible rolling mill of a cold rolling mill for rare and precious metals such as tantalum and niobium. It includes a motor 1, a gearbox 2, a roller table frame 3, conveyor rollers 4, baffles 5, bearing seats 6, and a motor frame 7.

[0035] like Figure 1 As shown, this embodiment includes six conveyor rollers 4, arranged in a row along the conveying direction with parallel axes. The roller surfaces of each conveyor roller 4 have evenly spaced flat cylindrical protrusions 41 along the axial direction. The cylindrical protrusions of adjacent conveyor rollers 4 interlock, ensuring that the cylindrical protrusions correspond to the gap areas of adjacent rollers, forming a continuous conveying trajectory. Specifically, the first flat cylindrical protrusion of the second conveyor roller on the left is located in the groove between the first and second flat cylindrical protrusions of the first conveyor roller on the left, with a gap between its end face and the groove. The cylindrical protrusions of adjacent conveyor rollers interlock.

[0036] The output shaft of the motor is connected to the input shaft of the gearbox via the first coupling 8. The output shaft of the gearbox is connected to the shaft of the conveyor rollers via the second coupling 9. The motor 1 drives the six conveyor rollers 4 to operate synchronously through the gearbox 2, realizing centralized transmission and meeting the conveying needs of rare and precious metal slabs of different thicknesses.

[0037] like Figure 2 As shown, the roller conveyor frame 3 is a box-shaped frame structure welded from high-strength steel plates. Its bottom surface is rigidly connected to the civil foundation through anchor bolts to ensure overall stability. The roller conveyor frame 3 includes a first roller conveyor frame 31 and a second roller conveyor frame 32. The bearing housing 6 includes a first bearing housing 61 and a second bearing housing 62. The first roller conveyor frame 31 and the second roller conveyor frame 32 are arranged on the left and right sides of the conveyor roller 4. The gearbox 2 is fixed to the first bearing housing 61 on the first roller conveyor frame 31, and the second bearing housing 62 is fixed to the second roller conveyor frame 32. The left and right ends of the shaft of the conveyor roller 4 are installed on the first bearing housing 61 and the second bearing housing 62.

[0038] Motor 1 is a geared motor. The base of motor 1 is fixed to motor frame 7 with bolts. The bottom surface of motor frame 7 is rigidly connected to the civil foundation with anchor bolts to ensure overall stability.

[0039] Baffles 5 are disposed on the left and right sides of the conveyor roller 4 and are fixedly connected to the roller frame 3. The baffles 5 are located between the end face of the bearing seat and the cylindrical protruding end face of the conveyor roller. Two baffles 5 are provided and are fixedly connected to the first roller frame 31 and the second roller frame 32 respectively.

[0040] The baffle 5 is formed by the baffle body 51, the support frame 52 and the mounting base 53. The support frame 52 provides rigid support for the baffle body 51, and the mounting base 53 is fixed to the roller frame 3 by bolts.

[0041] A 5-10mm gap is maintained between the baffle 5 and the neck of the conveyor roller 4. The baffle body 51 is made of high-strength wear-resistant steel plate to withstand frequent friction and impact from the billet. The support frame 52 is composed of welded steel structure, providing rigid support for the baffle 5 to ensure that it does not deform under lateral force. The mounting base 53 is fixed to the top surface of the roller frame 3 by bolts. The horizontal and verticality of the mounting plane must be ensured to prevent the workpiece from deviating due to baffle skewing.

[0042] like Figure 1 As shown, the baffle body 51 has outward bends at both ends, which facilitates the smooth entry and exit of the slab from the roller table and ensures smooth transmission.

[0043] When transporting thin slabs of rare and precious metals on the working roller conveyor of a rolling mill, this invention can effectively solve the common problem of steel jamming in traditional roller conveyors:

[0044] 1) Anti-drilling steel design for the flower roller structure

[0045] The roller body of the drive roller 4 adopts a specially optimized "flower roller" structure, and its stepped structure is precisely calculated and arranged; the stepped structure of the adjacent drive roller 4 adopts a strict phase difference design to ensure continuous support at any position; this structure makes the thin slab always in a state of coordinated support of multiple roller surfaces, completely eliminating the phenomenon of the billet drilling into the gap between adjacent drive rollers 4.

[0046] 2) Anti-jamming steel design for fixed side baffle 4

[0047] The fixed side baffle 4 is arranged between the ends of the drive rollers 4 and the bearing seats on both sides of the roller conveyor, and the fixed side baffle 4 and the roller neck of the drive roller 4 maintain a scientific gap of 5-10mm. This gap has been rigorously calculated and experimentally verified. When the billet deviates, the impact force is entirely borne by the upper part of the fixed side baffle 4. The unique installation position and gap design completely prevent the billet from entering the gap between the roller and the fixed side baffle 4.

[0048] 3) Dual protection mechanism

[0049] The patterned roller structure prevents steel from being drilled through from the roller surface contact angle, while the fixed side baffle layout eliminates steel jamming from the side guiding angle. The two work together to form a three-dimensional protection system.

[0050] This invention has been applied to actual production. Practical production verification has shown that when transporting tantalum and niobium slabs with a thickness of 0.3–2.0 mm, the rate of steel jamming is reduced to zero, while ensuring that the surface quality of the slabs is not damaged. It is particularly suitable for high-precision cold rolling processes. This invention effectively prevents steel jamming in thin slabs, improves production efficiency, and increases product qualification rate.

[0051] The scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
