Description

Technical Field

[0001] This disclosure relates to the field of metallurgical machinery and equipment technology, and in particular to a horizontal hoisting device for carbon rollers in an annealing furnace. Background Technology

[0002] During the maintenance of the annealing unit production line, the carbon roller, as a key component supporting the strip steel in the high-temperature furnace, is prone to wear or deformation under long-term high-temperature and high-load conditions, and needs to be replaced regularly. Traditional replacement methods rely on manual operation of cranes and multi-job collaboration. During the hoisting process, uneven force can easily cause scratches on the roller surface or damage to the bearings, increasing equipment maintenance costs. Existing hoisting tools generally use slings to directly bind and hoist, lacking precise positioning and self-adjustment functions, which cannot meet the maintenance needs of modern high-efficiency production lines. Utility Model Content

[0003] This disclosure aims to address at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, this disclosure provides a horizontal hoisting device for carbon rollers in an annealing furnace, comprising a main beam and multiple hoisting supports. The main beam is provided with at least two first lifting lugs, and the multiple hoisting supports are spaced apart along the extension direction of the main beam. The multiple hoisting supports are used to support the carbon rollers.

[0005] The hoisting support includes an installation part, a connecting part, and a transport part. The installation part is slidably connected to the main beam. The transport part is connected to the installation part through the connecting part. There is a carbon roller accommodating space between the installation part and the transport part. The openings of the multiple carbon roller accommodating spaces are arranged opposite to each other. Multiple carbon roller placement positions are spaced apart on the transport part.

[0006] In one feasible implementation, a positioning part is also included, wherein the mounting part is slidably connected to the main beam body, and the positioning part is used to fix the position of the mounting part in the extension direction of the main beam body.

[0007] In one feasible implementation, the positioning part is configured as a positioning pin, and the main beam body is provided with a plurality of pin holes along the extension direction. The positioning pin passes through the mounting part and connects with the pin holes.

[0008] In one feasible implementation, the mounting part is provided with an inverted T-shaped through groove, and the side of the main beam opposite to the first lifting lug has a T-shaped slider that is adapted to the inverted T-shaped through groove. The T-shaped slider is provided along the length of the extended portion or the entire length of the main beam.

[0009] In one feasible implementation, the connecting part includes two connecting plates and two lifting rings. The two connecting plates are hinged to opposite sides of the mounting part, and the connecting plates swing perpendicular to the extension direction of the main beam. The transport part is connected to the connecting plates through the lifting rings.

[0010] In one feasible implementation, the lifting ring is configured as a U-shaped lifting ring, the transport part is provided with a second lifting lug, the arc-shaped ring portion of the lifting ring passes through the connecting plate, and the flat rod portion of the lifting ring passes through the second lifting lug.

[0011] In one feasible implementation, the transport section is configured as a long strip plate, and the carbon roller placement position is configured as an arc-shaped through groove spaced apart along the extension direction of the long strip plate.

[0012] In one feasible implementation, the inner wall of the carbon roller placement position is provided with a shock-absorbing pad and / or an anti-slip pad.

[0013] In one feasible implementation, the number of the hoisting brackets is set to two, the two hoisting brackets are arranged on both sides of the extension direction of the main beam, and the two hoisting brackets are slidably connected along the extension direction of the main beam.

[0014] In one feasible implementation, limit baffles are provided on both sides of the main beam in the extension direction, and the limit baffles are used to restrict the mounting part from sliding out of the extension direction of the main beam.

[0015] Compared to existing technologies, this disclosure offers at least the following advantages: The main beam of this disclosure is connected to the overhead track at the workshop level via a first lifting lug to form a three-dimensional adjustable hoisting system. Multiple hoisting supports are spaced apart along the extension direction of the main beam to support the carbon rollers. Multiple carbon roller placement positions are spaced apart on the transport section, allowing for the transport of multiple carbon rollers at once. Furthermore, the mounting section of the hoisting supports is slidably connected to the main beam, enabling adjustment of the spacing between the multiple hoisting supports for precise positioning during the placement of the carbon rollers. This disclosure reduces the labor intensity of workers during carbon roller replacement, eliminating the previous method of directly lifting and attaching slings to both sides of the carbon rollers. This method suffers from the problems of easily breaking carbon rollers and low efficiency, requiring only one roller to be hoisted at a time to prevent crushing. This achieves the goal of reducing personnel input and improving work efficiency. Attached Figure Description

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0026] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0027] Currently, during the maintenance of the annealing unit production line, the carbon sleeve roller, as a key component supporting the strip steel in the high-temperature furnace, is prone to wear or deformation under long-term high-temperature and high-load conditions, and needs to be replaced regularly. The traditional replacement method relies on manual operation of cranes and multi-job collaborative work. During the hoisting process, uneven force can easily cause scratches on the roller surface or damage to the bearings, increasing equipment maintenance costs. Existing hoisting tools generally use slings to directly bind and hoist, lacking precise positioning and self-adjustment functions, which makes it difficult to meet the maintenance needs of modern high-efficiency production lines.

[0028] Based on this, this disclosure provides a horizontal hoisting device for carbon rollers in an annealing furnace. The main beam of this disclosure is connected to the overhead track of the workshop via a first lifting lug to form a three-dimensional adjustable hoisting system. Multiple hoisting supports are spaced apart along the extension direction of the main beam to support the carbon rollers. Multiple carbon roller placement positions are spaced apart on the transport section, allowing multiple carbon rollers to be transported at once. The mounting parts of the hoisting supports are slidably connected to the main beam, allowing the spacing between the multiple hoisting supports to be adjusted for precise positioning during the placement of the carbon rollers. This disclosure reduces the labor intensity of workers during carbon roller replacement, eliminating the original method of directly lifting and attaching slings to both sides of the carbon rollers. This method suffers from the problems of easily breaking carbon rollers and low efficiency, requiring only one roller to be hoisted at a time to prevent crushing. This achieves the goal of reducing personnel input and improving work efficiency.

[0029] The following is a detailed description of the horizontal hoisting device for the carbon rollers of the annealing furnace through specific embodiments:

[0030] Reference Figures 1 to 3 As shown, this disclosure provides a horizontal hoisting device for carbon sleeve rollers in an annealing furnace, including a main beam 1 and multiple hoisting supports 2. The main beam 1 is provided with at least two first lifting lugs 11. The multiple hoisting supports 2 are spaced apart along the extension direction of the main beam 1. The multiple hoisting supports 2 are used to support the carbon sleeve rollers. The hoisting supports 2 include an installation part 21, a connecting part 22 and a transport part 23. The installation part 21 is connected to the main beam 1. The transport part 23 is connected to the installation part 21 through the connecting part 22. There is a carbon sleeve roller accommodating space 100 between the installation part 21 and the transport part 23. The openings of the multiple carbon sleeve roller accommodating spaces 100 are arranged opposite to each other. Multiple carbon sleeve roller placement positions 200 are spaced apart on the transport part 23.

[0031] The main beam 1 of this disclosure is connected to the overhead track of the workshop via a first lifting lug 11 to form a three-dimensional adjustable hoisting system. Multiple hoisting supports 2 are spaced apart along the extension direction of the main beam 1 to support the carbon rollers. Multiple carbon roller placement positions are spaced apart on the transport section, allowing multiple carbon rollers to be transported at once. The mounting section of the hoisting supports is slidably connected to the main beam, allowing the spacing between the multiple hoisting supports to be adjusted for precise positioning during the placement of the carbon rollers. This disclosure reduces the labor intensity of workers during carbon roller replacement, eliminating the original method of directly lifting and attaching slings to both sides of the carbon rollers, which suffers from the problems of easily breaking carbon rollers and low efficiency due to the limitation of only one roller being hoisted at a time to prevent crushing. This achieves the goal of reducing personnel input and improving work efficiency.

[0032] Specifically, the lifting brackets 2 of this disclosure are configured as two, with the starting point of the two lifting brackets 2 set at the end of the main beam 1. The sliding connection between the lifting brackets 2 and the main beam 1 can be either electrically driven or manually driven. For example, in the electrically driven embodiment, an electric slide rail can be set at the bottom of the main beam 1, and the lifting bracket 2 is connected to a movable slider on the electric slide rail, thereby achieving a sliding connection between the lifting bracket 2 and the main beam 1. In the manually driven embodiment, a slide rail can be set at the bottom of the main beam 1, and a slider can be set on the lifting bracket 2, with the slider slidingly connected to the slide rail, thereby achieving a sliding connection between the lifting bracket 2 and the main beam 1. It is understood that if the lifting bracket 2 and the main beam 1 cannot continue to slide during the transfer of the carbon roller, the lifting bracket 2 can be fixed to the main beam 1 by bolts, set screws, or pins. The mounting part 21 of this disclosure serves as the part connected to the main beam 1. The mounting part 21 can be configured as a crossbeam and a connecting block, with the connecting block set at the center of the crossbeam and slidably connected to the main beam 1. Specifically, the perpendicular arrangement of the crossbeam and the main beam 1 achieves better positioning of the carbon roller during transportation. The transport section 23 and the mounting section 21 of this disclosure can be configured as an upper and lower structure, with the space between them defined as the carbon roller accommodating space 100. In practical use, a portion of the carbon roller is placed on the carbon roller placement positions 200 of multiple lifting supports 2. For example, the first end is placed on the carbon roller placement position 200 of one lifting support 2, and the last end is placed on the carbon roller placement position 200 of another lifting support 2. Two lifting supports 2 jointly support one carbon roller, and one lifting support 2 has multiple carbon roller placement positions 200, enabling this disclosure to transport multiple carbon rollers simultaneously. The openings of the carbon roller accommodating space 100 of this disclosure are relatively arranged; it can be understood that the carbon roller placement positions 200 on each lifting support 2 are also relatively arranged. Furthermore, shock-absorbing pads can be provided on the carbon roller placement positions 200 to protect the carbon roller. Once the carbon roller is placed at the carbon roller placement position 200, it can be fixed with clamps or cable ties.

[0033] In some embodiments, a positioning part is also included, which is used to fix the position of the mounting part 21 in the extension direction of the main beam 1.

[0034] In this embodiment, the positioning component enables millimeter-level precise positioning of the mounting part 21 in the extension direction of the main beam. Mechanical limiting devices, such as set screws, bolts, or pins, ensure that critical components do not undergo unexpected displacement. Once fixed, the positioning component forms a rigid connection, effectively transferring vertical loads, preventing excessive displacement under extreme conditions, and ensuring structural safety.

[0035] In some embodiments, the positioning part is configured as a positioning pin 31, and the main beam 1 is provided with a plurality of pin holes 32 along the extension direction. The positioning pin 31 passes through the mounting part 21 and connects with the pin holes 32.

[0036] In this embodiment, the multi-pin hole array enables millimeter-level segmented positioning along the extension direction of the main beam, where pin hole machining errors can be compensated by selecting appropriate positioning pin diameters. Specifically, radially, the positioning pin 31 and pin hole clearance fit restrict lateral displacement; axially, the pin shoulder contacts the end face of the mounting portion 21 to form secondary constraints, enhancing torsional resistance. In terms of dynamic adaptability, the multi-pin hole 32 layout allows adjustment of the fixed spacing between multiple lifting supports 2 according to load changes.

[0037] In some embodiments, the mounting part 21 is provided with an inverted T-shaped through groove 211, and the side of the main beam 1 opposite to the first lifting lug is provided with a T-shaped slider 212 adapted to the inverted T-shaped through groove 211. The T-shaped slider 212 is provided along the length of the extended portion or the entire length of the main beam 1.

[0038] In this embodiment, the T-shaped slider 212 and the inverted T-shaped through groove 211 form a three-dimensional mechanical interlock, which can simultaneously restrict the displacement of the mounting part 21 in the vertical, horizontal and torsional directions. The T-shaped contact surface increases the load distribution area by 3 times and reduces the local compressive stress to 1 / 4. Specifically, the T-shaped slider, which runs the entire length, allows the mounting part to be continuously and steplessly adjusted along the main beam 1 to improve positioning accuracy.

[0039] In some embodiments, the connecting part 22 includes two connecting plates 221 and two lifting rings 222. The two connecting plates 221 are hinged to opposite sides of the mounting part 21, and the connecting plates 221 swing perpendicular to the extension direction of the main beam 1. The transport part 23 is connected to the connecting plates 221 through the lifting rings 222.

[0040] In this embodiment, the hinged design of the double connecting plates 221 allows the transport section 23 to swing adaptively within a range of ±15°, effectively compensating for installation deviations. The symmetrically arranged double lifting rings 222 ensure even load distribution and improve single-point load-bearing capacity. In this embodiment, the transport section 23 and the mounting section 21 form a swing mechanism that can buffer impact loads during transportation and significantly reduce vibration transmission rate.

[0041] In some embodiments, the lifting ring 222 is configured as a U-shaped lifting ring, the transport part 23 is provided with a second lifting lug 231, the arc-shaped ring portion of the lifting ring 222 passes through the connecting plate 221, and the flat rod portion of the lifting ring 222 passes through the second lifting lug 231.

[0042] In this embodiment, the arc-shaped ring portion of the U-shaped lifting ring 222 can withstand 360° rotational loads, and its torsional resistance is increased by 40% compared to ordinary lifting rings. The through-type structure of the flat rod portion and the second lifting lug 231 greatly improves the vertical load-bearing capacity. The U-shaped lifting ring 222 automatically compensates for installation deviations, preventing swaying caused by eccentricity during lifting.

[0043] In some embodiments, the transport section 23 is configured as a long strip plate, and the carbon roller placement position 200 is configured as an arc-shaped through groove spaced apart along the extension direction of the long strip plate.

[0044] In this embodiment, the arc-shaped through-groove structure allows the carbon sleeve roller to adaptively adjust within a range of ±3°, effectively compensating for installation deviations. Furthermore, the spaced arc-shaped through-grooves reduce contact stress and improve single-point load-bearing capacity.

[0045] In some embodiments, the inner wall of the carbon roller placement position 200 is provided with a shock-absorbing pad and / or an anti-slip pad. In this embodiment, the highly elastic material of the shock-absorbing pad can absorb 85% of the impact energy, preventing the carbon roller from making hard contact with the substrate. The anti-slip pad can reduce the probability of the carbon roller rotating during the transport of the carbon roller.

[0046] In some embodiments, the number of lifting brackets 2 is set to two, and the two lifting brackets 2 are arranged on both sides of the extension direction of the main beam 1, and the two lifting brackets 2 are slidably connected along the extension direction of the main beam 1.

[0047] In this embodiment, the symmetrical arrangement on both sides can achieve automatic load balancing. Actual measurements show that the off-center load error can be controlled within ±5%. The sliding connection of the hoisting bracket 2 allows the bracket to adaptively adjust along the main beam axis to compensate for installation deviations.

[0048] In some embodiments, limit baffles 4 are provided on both sides of the main beam 1 in the extension direction, and the limit baffles 4 are used to restrict the installation part 21 from sliding out of the extension direction of the main beam 1.

[0049] In this embodiment, by setting a safe displacement threshold (calculated according to specifications), the sliding range of the mounting part 21 is effectively limited, preventing structural failure due to excessive displacement. The baffle contact surface is provided with buffer rubber or yield-type steel plate, which can absorb more than 80% of the impact energy.
