Description

Technical Field

[0001] This utility model belongs to the field of fixing structure technology, and in particular relates to a fixing device for hot-rolled steel coils. Background Technology

[0002] Hot-rolled steel coils are steel billets (such as continuously cast billets) heated to a high temperature (typically 1100-1300℃, when the steel is in a plastic state) and continuously rolled through a rolling mill (such as a hot strip mill) to gradually thin and extend the billet, ultimately forming a steel plate of a specific thickness. The rolled steel plate is then coiled into coils by a coiler (for convenient storage and transportation), or cut into flat sheets of fixed length as needed; hence, they are collectively called hot-rolled steel coils. Hot-rolled steel coils have advantages such as high strength, low cost, and ease of processing, and are therefore widely used in many core industries such as construction, machinery, and automobiles. Because hot-rolled steel coils are in coil form, they need to be secured to prevent rolling, displacement, and collisions during storage or transportation, to avoid deformation and surface scratches, and to ensure operational safety.

[0003] According to the search, a transportation fixing mechanism for large-diameter steel plate coils with the publication number CN216187268U is disclosed on the Chinese Patent Network. This fixing mechanism can effectively prevent the large-diameter steel plate coils from rolling by the top support mechanism on both sides and the pull rope around the top of the large-diameter steel plate coils, thus improving the stability during transportation. It can be used for fixing large-diameter steel plate coils with different outer diameters and for most flatbed trucks on the market. However, there are some defects and shortcomings that need to be improved: (1) Some existing fixing structures are often only for the radial direction of the plate coil material, and lack effective axial fixing. When the transport vehicle makes a sharp turn, the plate coil material is prone to axial displacement due to inertia, which will cause it to fall off the transport vehicle. (2) In order to enhance the fixing effect, some existing fixing structures usually use steel strips or chains to tie the plate coil material. This process is often done manually, which is not only time-consuming and laborious, but also difficult to quickly adjust the tightness of the steel strip according to the diameter of the plate coil material. Therefore, the fixing device for hot-rolled steel coils provided by this utility model is of great significance in addressing the above problems. Utility Model Content

[0004] This invention provides a fixing device for hot-rolled steel coils. A first fixing component secures the coil radially to prevent rolling during sudden braking or bumps in the transport vehicle. A second fixing component secures the coil axially to prevent axial displacement during sharp turns in the transport vehicle. The distance between the first and second fixing components can be adjusted according to the diameter and length of the coil. A winding component tightens multiple binding straps to secure the coil, further enhancing the fixing effect. By controlling the forward and reverse rotation of the winding roller, the tightness of the binding straps can be quickly adjusted according to the coil diameter. The entire binding and tightness adjustment process is manual, saving time and effort and effectively reducing the workload of workers. In summary, this invention solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a fixing device for hot-rolled steel coils, including a base plate, a fixing platform fixedly connected to the top of the base plate, a steel coil placed on the fixing platform, and a first bracket and a second bracket fixedly connected to the left and right sides and the front and rear sides of the fixing platform, respectively. The first brackets are symmetrically distributed on the left and right sides of the fixing platform and are provided with a first fixing component. The second brackets are symmetrically distributed on the front and rear sides of the fixing platform and are provided with a second fixing component. A pair of roller frames are fixedly connected to the top two sides of the base plate, the roller frames are symmetrically distributed on the left and right sides of the fixing platform, and each pair of roller frames is provided with a winding component.

[0007] The first fixing component includes a first electric telescopic rod, which is installed on the side wall of the first bracket. A stop block is fixedly connected to the end of its output shaft. The stop block is a right trapezoid with an inclined end face on the side near the plate roll. Several first protective pads are provided on the surface of the stop block.

[0008] The second fixing component includes a second electric telescopic rod, which is installed on the side wall of the second bracket. A transmission frame is fixedly connected to the end of its output shaft. The transmission frame is U-shaped, and baffles are fixedly connected to both ends of the frame. A second protective pad is provided on the side of the baffle closest to the plate roll.

[0009] The winding assembly includes a motor mounted on a roller frame, the end of which is mounted on another roller frame via a bearing, and a winding roller is fixedly connected to the output shaft of the motor. The winding roller is located between each pair of roller frames, and several binding straps are wound around the winding roller. Each binding strap goes around the top of the coil, and its end is wound around another winding roller.

[0010] Furthermore, the bottom of the base plate is provided with several anti-slip pads, which are long strips and are distributed linearly at equal intervals along the length of the base plate, and the bottom surface of the anti-slip pads is provided with herringbone anti-slip patterns.

[0011] Furthermore, a pair of guide grooves are provided on the top surface of the fixed platform, and a pair of guide blocks are fixedly connected to the bottom of each stop. The width of the guide blocks is equal to the width of the guide grooves, and each stop is located in the corresponding guide groove.

[0012] Furthermore, the surface of the stop block is provided with a plurality of slots, which are equidistantly linearly distributed along the length of the stop block, and the width of the first protective pad is equal to the width of the slots.

[0013] Furthermore, the baffle is elongated and symmetrically distributed on both sides of the second support, and several reinforcing blocks are fixedly connected between the two baffles.

[0014] Furthermore, the surface of the take-up roller is provided with a plurality of grooves, which are equidistantly distributed linearly along the axial direction of the take-up roller, and the width of the binding tape is equal to the width of the grooves.

[0015] The present invention has the following advantages over the prior art:

[0016] (1) The plate roll can be effectively fixed from multiple directions with good fixing effect: the first fixing component can fix the plate roll from the radial direction to prevent the plate roll from rolling when the transport vehicle brakes suddenly or bumps; the second fixing component can fix the plate roll from the axial direction to prevent the plate roll from axial displacement when the transport vehicle makes a sharp turn; and the distance between the first fixing component and the second fixing component can be adjusted according to the diameter and length of the plate roll.

[0017] (2) The fixing effect of the plate roll can be enhanced by the binding straps. The binding and tension adjustment of the binding straps do not require manual labor: Multiple binding straps can be tightened by the winding assembly so that the plate roll can be bound by the binding straps, thereby further enhancing the fixing effect of the plate roll. By controlling the forward and reverse rotation of the winding roller, the binding tension of the binding straps can be quickly adjusted according to the diameter of the plate roll. The entire binding and tension adjustment process does not require manual labor, which not only saves more time and effort, but also effectively reduces the workload of the staff.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1-7 As shown, a fixing device for hot-rolled steel coils according to the present invention includes a base plate 1, a fixing platform 2 fixedly connected to the top of the base plate 1, a steel coil 3 placed on the fixing platform 2, and a first bracket 4 and a second bracket 5 fixedly connected to the left and right sides and the front and rear sides of the fixing platform 2, respectively. The first bracket 4 is symmetrically distributed on the left and right sides of the fixing platform 2 and is provided with a first fixing component. The second bracket 5 is symmetrically distributed on the front and rear sides of the fixing platform 2 and is provided with a second fixing component. A pair of roller frames 6 are fixedly connected to the top two sides of the base plate 1, and the roller frames 6 are symmetrically distributed on the left and right sides of the fixing platform 2. Each pair of roller frames 6 is provided with a winding component.

[0032] The first fixing component includes a first electric telescopic rod 7, which is installed on the side wall of the first bracket 4. A stop block 8 is fixedly connected to the end of its output shaft. The stop block 8 is a right-angled trapezoid with an inclined end face on the side closest to the plate roll 3. Several first protective pads 9 are provided on the surface of the stop block 8. Driving the first electric telescopic rod 7 can move the stop block 8 left and right. When the stop block 8 is in contact with the left and right sides of the plate roll 3, it can fix the plate roll 3 radially to prevent it from rolling when the transport vehicle brakes suddenly or bumps. The spacing of the stop blocks 8 can be determined according to the diameter of the plate roll 3. The size can be adjusted. The first protective pad 9 can be made of elastic materials such as sponge. When the stop block 8 is attached to the left and right sides of the plate roll 3, the first protective pad 9 can be placed between the plate roll 3 and the stop block 8 to play a flexible protection role, thereby preventing the stop block 8 and the radial surface of the plate roll 3 from colliding and wearing due to direct contact. Specifically, the angle between the inclined end face of the stop block 8 and the top surface of the fixed platform 2 is 30°-60°, and the radius of curvature of the inclined end face is consistent with the radius of curvature of the outer circle of the plate roll 3, so as to ensure that the contact area between the stop block 8 and the plate roll 3 is not less than 80% of the area of ​​the inclined end face of the stop block 8.

[0033] The second fixing component includes a second electric telescopic rod 10, which is installed on the side wall of the second bracket 5. A transmission frame 11 is fixedly connected to the end of its output shaft. The transmission frame 11 is U-shaped, and baffles 12 are fixedly connected to both ends of its two sides. A second protective pad 13 is provided on the side of the baffle 12 near the plate roll 3. By driving the second electric telescopic rod 10, the transmission frame 11 and the baffles 12 on both sides can be moved back and forth. When the baffles 12 are attached to the front and rear sides of the plate roll 3, the plate roll 3 can be fixed in the axial direction to prevent the plate roll 3 from axial displacement when the transport vehicle makes a sharp turn. The spacing of the baffles 12 can be adjusted according to the length of the plate roll 3. The second protective pad 13 can be made of elastic materials such as sponge and fixed by adhesives. When the baffles 12 are attached to the front and rear sides of the plate roll 3, the second protective pad 13 can be placed between the plate roll 3 and the baffles 12 to play a flexible protection role, thereby preventing the baffles 12 and the axial surface of the plate roll 3 from colliding and abrading due to direct contact.

[0034] The winding assembly includes a motor 14, which is mounted on a roller frame 6. The end of the motor 14's output shaft is mounted on another roller frame 6 via a bearing. A winding roller 15 is fixedly connected to the output shaft of the motor 14. The winding roller 15 is located between each pair of roller frames 6, and several binding straps 16 are wound around the winding roller 15. Each binding strap 16 wraps around the top of the plate roll 3, and its end is wound around another winding roller 15. The motor 14 drives the winding roller 15 to rotate. When the winding roller 15 rotates, the binding straps 16 can be tightened from both sides. At this time, the plate roll 3 can be bound by the binding straps 16, thereby further enhancing the fixing effect of the plate roll 3. By controlling the forward and reverse rotation of the winding roller 15, the binding looseness of the binding straps 16 can be quickly adjusted according to the diameter of the plate roll 3. The entire binding and adjustment process is completed without manual intervention, saving time and effort and significantly reducing the workload of workers. Specifically, the winding assembly can be equipped with a tension sensor (model: YZC-526) and a PLC controller (model: S7-200) (not shown in the figure). The tension sensor is installed between the binding tape 16 and the winding roller 15 to detect the tension of the binding tape 16 in real time. The controller is electrically connected to the tension sensor and the two motors 14 on both sides. The tension threshold is preset (500N-1000N, adjusted according to the weight of the coil 3). When the tension reaches the threshold, the controller stops the motor 14. When the tension is below 80% of the threshold, the controller controls the motor 14 to rotate forward to tighten. The two motors 14 on both sides are synchronously controlled by the same controller, with a synchronization error of ≤0.5s.

[0035] The base plate 1 has several anti-slip pads 17 at its bottom. The anti-slip pads 17 are long strips and are distributed linearly at equal intervals along the length of the base plate 1. The bottom surface of the anti-slip pads 17 is provided with herringbone anti-slip patterns. The anti-slip pads 17 can be made of elastic materials such as rubber and are fixed by adhesives. When the fixing device is placed on the ground or on a transport vehicle, the anti-slip patterns on the bottom surface of each anti-slip pad 17 can increase the friction between the base plate 1 and the contact surface to play an anti-slip role, thereby preventing the fixing device from slipping and shifting.

[0036] The top surface of the fixed platform 2 is provided with a pair of guide grooves 18. Each stop block 8 is fixedly connected to a pair of guide blocks 19 at its bottom. The width of the guide blocks 19 is equal to the width of the guide grooves 18. Each stop block 8 is located in the corresponding guide groove 18. When the spacing of the stop blocks 8 is adjusted, the stop blocks 8 can drive the guide blocks 19 to move along the guide grooves 18. At this time, the mutual cooperation between the guide blocks 19 and the guide grooves 18 can play a role in limiting and guiding, so as to ensure that the stop blocks 8 always move left and right in a straight line, thereby preventing the position of the stop blocks 8 from shifting or tilting and affecting its radial fixing effect on the plate roll 3.

[0037] The surface of the stop block 8 is provided with several slots 20, which are linearly distributed at equal intervals along the length of the stop block 8. The width of the first protective pad 9 is equal to the width of the slot 20. The first protective pad 9 can be inserted into and fitted into the corresponding slot 20 to fix the first protective pad 9 by means of insertion, thereby preventing the first protective pad 9 from falling off during the fixing process of the plate roll 3. When the first protective pad 9 is damaged due to prolonged direct contact with the surface of the plate roll 3, it can be removed from the corresponding slot 20 for quick replacement of the damaged first protective pad 9.

[0038] Among them, the baffle 12 is long and strip-shaped and symmetrically distributed on both sides of the second bracket 5. Several reinforcing blocks 21 are fixedly connected between the two baffles 12. The reinforcing blocks 21 are X-shaped and are equidistantly linearly distributed along the length of the baffle 12. When the plate roll 3 is axially fixed, the two baffles 12 can simultaneously fit against the axial end face of the plate roll 3 from both sides to ensure that the axial end face of the plate roll 3 is subjected to more uniform force. At the same time, it can increase the contact area between the second fixing component and the axial end face of the plate roll 3. The two baffles 12 can be reinforced by multiple reinforcing blocks 21 to improve the structural strength of the baffles 12, thereby preventing them from bending and deforming after being subjected to force for a long time.

[0039] The surface of the take-up roller 15 is provided with several grooves 22, which are equidistantly distributed linearly along the axial direction of the take-up roller 15. The width of the binding tape 16 is equal to the width of the grooves 22. The two ends of each binding tape 16 can be wound into the corresponding grooves 22 on the surfaces of the two take-up rollers 15, and the two sides of each binding tape 16 can be attached to the inner walls of the two sides of the grooves 22. At this time, the binding tape 16 can be limited by the grooves 22 to prevent its position from shifting and affecting the binding effect of the plate roll 3.

[0040] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0041] The working principle of this utility model is as follows:

[0042] In use, this device can be placed on the ground or on a transport vehicle. When it is necessary to fix the hot-rolled coil, the coil 3 to be transported can be transferred and placed on the fixed platform 2 using external hoisting equipment. Then, the two first electric telescopic rods 7 are driven to move the two stops 8 left and right until the stops 8 are in contact with the left and right sides of the coil 3, so that the coil 3 can be fixed radially by the stops 8, thereby preventing the coil 3 from rolling when the transport vehicle brakes suddenly or bumps. The spacing of the stops 8 can be adjusted according to the diameter of the coil 3. Next, the two second electric telescopic rods 10 are driven to move the two transmission frames 11 and the baffles 12 on both sides back and forth until the baffles 12 are in contact with the front and rear sides of the coil 3, so that the coil 3 can be fixed axially by the baffles 12. The roll 3 is fixed to prevent axial displacement of the roll 3 when the transport vehicle makes a sharp turn. The spacing of the baffles 12 can be adjusted according to the length of the roll 3. Then, the two ends of multiple binding straps 16 are wrapped around the two take-up rollers 15 respectively, so that the binding straps 16 pass over the top of the roll 3. The take-up rollers 15 can be rotated by the drive motor 14. When the take-up rollers 15 rotate, the binding straps 16 can be tightened from both sides. At this time, the roll 3 can be bound by the binding straps 16, thereby further enhancing the fixing effect of the roll 3. By controlling the forward and reverse rotation of the take-up rollers 15, the binding tightness of the binding straps 16 can be quickly adjusted according to the diameter of the roll 3. The entire binding and adjustment process does not require manual labor, which not only saves time and effort, but also effectively reduces the workload of the staff.
