Description

Technical Field

[0001] This application relates to the technical field of steel coil installation equipment, and in particular to a support structure for auxiliary installation of steel coils. Background Technology

[0002] An uncoiler is a specialized piece of equipment for leveling metal sheets. It is used to level steel sheets and uneven sheets. Depending on the configuration, it can be used to form an uncoiler, leveling, and shearing production line and other sheet metal product production lines. Because steel strip coils are heavy, a support device is needed to support the steel strip coil when it is uncoiled by the uncoiler to ensure that the uncoiler can uncoil smoothly. When uncoiling the steel coil, it needs to be installed on the mandrel of the uncoiler.

[0003] The existing announcement number is CN216105019U, entitled "A Steel Strip Coil Support Device for an Uncoiling Machine." This device facilitates support for steel strip coils of different diameters and during uncoiling, reducing pressure on the uncoiling shaft. It also allows for overall height adjustment of the arc-shaped support plate and multiple guide shafts, increasing the range of supported steel strip coil thicknesses. Furthermore, it facilitates positional movement and locking of the device. The device includes a support frame with multiple moving mechanisms mounted at its bottom. Multiple screws mesh on the support frame. A fixed plate and a support plate are respectively located below and above the support frame. Multiple screws are rotatably connected to the fixed plate via rotating shafts, and to the support plate. A motor is mounted on the fixed plate, and its output is connected to multiple rotating shafts via a transmission mechanism. An arc-shaped support box is mounted on the support plate, and multiple support mechanisms are mounted on the arc-shaped support box.

[0004] Regarding the aforementioned related technologies, the inventors discovered that the above-mentioned steel coil support equipment uses multiple support rollers to support the steel coil. Due to the large weight of the steel coil, after prolonged use, the journals of the multiple support rollers are subjected to the pressure of the steel coil's weight for an extended period, leading to frequent damage to the journals of the support rollers. Since the support rollers and journals are integrally formed, it is necessary to disassemble and replace the damaged support rollers. However, discarding undamaged support rollers results in high costs and reduces the utilization efficiency of the support rollers. Utility Model Content

[0005] To overcome the problem that the journal of the existing support roller is subjected to the pressure of the weight of the steel coil for a long time, which often leads to the frequent damage of the journal, the support roller and the journal are integrally formed. At this time, it is necessary to disassemble the damaged support roller for replacement. However, the discarded support roller body is undamaged, and direct disposal and replacement is costly and reduces the utilization efficiency of the support roller. This application provides a support structure for auxiliary installation of steel coil.

[0006] The supporting structure for auxiliary installation of steel coils provided in this application adopts the following technical solution: A support structure for auxiliary installation of steel coils includes a heavy-duty AGV trolley, a lifting component, and support rollers. The lifting component is vertically mounted on the top of the heavy-duty AGV trolley. The lifting component includes a pallet, and a C-shaped groove frame is vertically fixed on the top surface of the pallet. Multiple rotating seats are evenly and symmetrically fixed on both sides of the inner arc surface of the groove frame. Bearings are fixedly installed inside the multiple rotating seats. Multiple support rollers are provided, and the multiple support rollers are horizontally assembled between the rotating seats on both sides of the groove frame. Threaded grooves are horizontally opened at the center of both ends of the support rollers, and journals can be detachably provided at the center of both ends of the support rollers. One end of the journal is integrally formed with a threaded shaft, and the threaded shaft is threadedly assembled in the threaded groove of the support roller. The other end of the journal is installed in the bearing inside the rotating seat.

[0007] By adopting the above technical solution, when feeding steel coils into the uncoiler, the steel coil to be fed is hoisted and placed in the slot frame of the top tray of the lifting component. Then, the heavy-duty AGV trolley is started to carry the steel coil and move it to the installation position. Then, the lifting component is started to lift the steel coil on the heavy-duty AGV trolley to a suitable installation height. Then, the steel coil is installed on the uncoiler, thus completing the installation of the steel coil on the uncoiler. During use, support rollers are used to support the steel coil. The journals at the center of both ends of the support roller are assembled into the threaded grooves at the center of both ends of the support roller through the threaded shafts at the ends of the journals. The journals are detachably assembled with the support roller. If the journal is damaged during use, the journal and the support roller are disassembled and the journal is replaced. Therefore, the roller body of the support roller is not discarded as a whole. By disassembling the journal and the support roller to replace the journal, the support roller can be quickly reused, reducing replacement costs and improving the utilization rate of the support roller.

[0008] Optionally, a first clamp and a second clamp are respectively fitted on both sides of the journal, and both the first clamp and the second clamp have horizontal through screw holes.

[0009] By adopting the above technical solution, the journal is provided with a first cover and a second cover on both sides of the rotary seat, and the first cover and the second cover are used to assemble the pressure bearing and stably install it in the rotary seat.

[0010] Optionally, the rotary table has horizontally opened screw holes, and the first and second clamps are fixedly assembled on the rotary table by locking screws.

[0011] By adopting the above technical solution, the locking screw is used to pass through the screw hole on the rotator and the first and second clips, thereby assembling the first and second clips to ensure the stability of the bearing in the rotator.

[0012] Optionally, the top surface of the heavy-duty AGV is horizontally fixed with rods on both sides, and sliding blocks are horizontally slidably assembled on both sides of the rods.

[0013] By adopting the above technical solution, symmetrical sliding blocks are installed on the horizontally fixed rods on both sides of the top surface of the heavy-duty AGV trolley, which are used to support the lifting components to lift vertically on the top surface of the heavy-duty AGV trolley.

[0014] Optionally, a support arm is rotatably connected to the top surface of the sliding block, and the top end of the support arm is rotatably connected to the bottom surface of the support plate.

[0015] By adopting the above technical solution, when the lifting component is vertically raised and lowered on the top surface of the heavy-duty AGV, it is rotatably connected to the top surface of the sliding block by the bottom end of the support arm, which is used to rotate and push the lifting component to vertically raise and lower on the top surface of the heavy-duty AGV.

[0016] Optionally, both ends of the top surface of the heavy-duty AGV are vertically fixed with lifting hydraulic rods, and the top of the lifting hydraulic rods is fixed to the bottom surface of the pallet.

[0017] By adopting the above technical solution, the lifting component is raised upward on the heavy-duty AGV trolley during use. The hydraulic rod of the lifting component extends and pushes the pallet on the lifting component to move vertically upward on the heavy-duty AGV trolley. The upward-moving pallet pulls the support arm to deflect and extend, so that the two ends of the support arm deflect on the bottom surface of the pallet and the sliding block respectively, reaching the appropriate steel coil installation height.

[0018] Optionally, a double-headed hydraulic rod is horizontally fixed in the middle of the top surface of the heavy-duty AGV, and both ends of the double-headed hydraulic rod are horizontally fixed with pins.

[0019] By adopting the above technical solution, in order to ensure the height stability of the lifting component supporting the steel coil during installation, the double-headed hydraulic rod is activated to extend and drive the pin to slide horizontally, thereby using the pin limit device to maintain the height of the lifting component supporting the steel coil during installation.

[0020] Optionally, locking hole strips are horizontally fixed at adjacent ends of the sliding hole blocks on both sides of the rod frame, and multiple insertion holes are horizontally opened on the locking hole strips, and the insertion holes on the locking hole strips are inserted into the pins.

[0021] By adopting the above technical solution, the double-headed hydraulic rod is activated to extend and drive the pin to slide horizontally. The pin is inserted into the locking holes on both sides of the rod frame, thereby limiting the sliding block to slide on the rod frame, and thus limiting the insertion to maintain the height of the lifting component supporting the steel coil installation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: When loading steel coils into the uncoiler, the coils are hoisted and placed in the slot frame of the top tray of the lifting device. Then, the heavy-duty AGV trolley is started to carry the coils and move them to the installation position. The lifting device is then started to lift the coils on the heavy-duty AGV trolley to the appropriate installation height. The coils are then installed on the uncoiler, thus completing the installation of the steel coils on the uncoiler. Support rollers are used to support the steel coils. The journals at the center of both ends of the support rollers are assembled into the threaded grooves at the center of both ends of the support rollers through the threaded shafts at the ends of the journals. The journals are detachably assembled with the support rollers. If the journals are damaged during use, the journals and support rollers are disassembled and the journals are replaced, thus avoiding the need to discard the entire support roller body. By disassembling the journals and supporting rollers to replace the journals, the support rollers can be quickly reused, reducing replacement costs and improving the utilization rate of the support rollers.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a support structure for auxiliary installation of steel coils. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A support structure for auxiliary installation of steel coils includes a heavy-duty AGV trolley 1, a lifting component 2, and support rollers 3. The lifting component 2 is lifted and lowered above the heavy-duty AGV trolley 1. The lifting component 2 includes a pallet 21. A C-shaped groove frame is vertically fixed on the top surface of the pallet 21. Multiple rotating seats 22 are evenly and symmetrically fixed on both sides of the inner arc surface of the groove frame of the pallet 21. Bearings are fixedly installed inside the multiple rotating seats 22. Multiple support rollers 3 are provided. The multiple support rollers 3 are horizontally assembled between the rotating seats 22 on both sides of the groove frame. Threaded grooves 31 are horizontally opened at the center of both ends of the support rollers 3. A journal 32 can be detachably provided at the center of both ends of the support rollers 3. A threaded shaft 33 is integrally formed at one end of the journal 32. The threaded shaft 33 is threadedly assembled in the threaded groove 31 of the support roller 3. The other end of the journal 32 is installed in the bearing inside the rotating seat 22. When feeding steel coils into the uncoiler, the steel coil to be fed is hoisted and placed in the slot frame of the top support plate 21 of the lifting component 2. Then, the heavy-duty AGV trolley 1 is started to carry the steel coil and move it to the installation position. Then, the lifting component 2 is started to lift the steel coil on the heavy-duty AGV trolley 1 to a suitable installation height. Then, the steel coil is installed on the uncoiler, thus completing the installation of the steel coil on the uncoiler. During use, support rollers 3 are used to support the steel coil. The journals 32 at the center of both ends of the support roller 3 are threaded into the threaded grooves 31 at the center of both ends of the support roller 3 through the threaded shafts 33 at the ends of the journals 32. The journals 32 can be detachably assembled with the support roller 3. If the journals 32 are damaged during use, the journals 32 and the support roller 3 are disassembled and replaced with the journals 32. Thus, the roller body of the support roller 3 is not discarded as a whole. By disassembling the journals 32 and the support roller 3 and replacing the journals 32, the support roller 3 can be quickly reused, reducing replacement costs and improving the utilization rate of the support roller 3.

[0027] Reference Figure 4 and Figure 5 A first cover 23 and a second cover 24 are respectively fitted onto the outer sides of the journal 32 on both sides of the rotary seat 22, and both the first cover 23 and the second cover 24 have horizontally through-holes. The first cover 23 and the second cover 24 are used to assemble and stably mount the bearing in the rotary seat 22. The rotary seat 22 has horizontally through-holes, and the first cover 23 and the second cover 24 are fixedly assembled onto the rotary seat 22 by locking screws 25. In use, the locking screws 25, threaded through the screw holes on the rotary seat 22 and the first cover 23 and the second cover 24, are used to assemble the first cover 23 and the second cover 24, thus ensuring the stability of the bearing mounted in the rotary seat 22.

[0028] Reference Figure 3The heavy-duty AGV trolley 1 has horizontally fixed rods 11 on both sides of its top surface, and sliding blocks 12 are horizontally slidably assembled on both sides of the rods 11. The sliding blocks 12, symmetrically slidably mounted on the horizontally fixed rods 11 on both sides of the top surface of the heavy-duty AGV trolley 1, are used to support the lifting component 2 to vertically lift and lower on the top surface of the heavy-duty AGV trolley 1. A support arm 13 is rotatably connected to the top surface of the sliding block 12, and the top end of the support arm 13 is rotatably connected to the bottom surface of the support plate 21. When the lifting component 2 vertically lifts and lowers on the top surface of the heavy-duty AGV trolley 1, it is rotatably connected to the top surface of the sliding block 12 via the bottom end of the support arm 13, which is used to rotate and push the lifting component 2 vertically up and down on the top surface of the heavy-duty AGV trolley 1. Lifting hydraulic rods 15 are vertically fixed at both ends of the top surface of the heavy-duty AGV trolley 1, and the top ends of the lifting hydraulic rods 15 are fixed to the bottom surface of the support plate 21. During use, the lifting component 2 is activated and lifted upward on the heavy-duty AGV trolley 1. The hydraulic rod 15 is activated and extends to push the pallet 21 on the lifting component 2 to move vertically upward on the heavy-duty AGV trolley 1. The upward-moving pallet 21 pulls the support arm 13 to deflect and extend, so that the two ends of the support arm 13 deflect on the bottom surface of the pallet 21 and the sliding block 12 respectively, reaching the appropriate steel coil installation height.

[0029] Reference Figure 3 A double-headed hydraulic rod 16 is horizontally fixed at the center of the top surface of the heavy-duty AGV trolley 1, and pins 17 are horizontally fixed at both ends of the double-headed hydraulic rod 16. To ensure the height stability of the lifting component 2 supporting the steel coil during installation, the double-headed hydraulic rod 16 is extended, causing the pins 17 to slide horizontally. The pins 17 then limit the insertion and maintain the height of the lifting component 2 supporting the steel coil. Locking hole strips 14 are horizontally fixed at adjacent ends of the sliding block 12 on both sides of the frame 11. Multiple insertion holes are horizontally opened on the locking hole strips 14, and these insertion holes are connected to the pins 17. When the double-headed hydraulic rod 16 is extended, the pins 17 slide horizontally, penetrating and inserting into the insertion holes of the locking hole strips 14 on both sides of the frame 11. This limits the sliding of the sliding block 12 on the frame 11, thereby limiting the insertion and maintaining the height of the lifting component 2 supporting the steel coil.

[0030] The implementation principle of the support structure for auxiliary installation of steel coils in this application embodiment is as follows: When feeding steel coils into the uncoiler during use, the steel coil to be fed is hoisted and placed in the slot frame of the top support plate 21 of the lifting component 2. Then, the heavy-duty AGV trolley 1 is started to carry the steel coil and move it to the installation position. Then, the lifting hydraulic rod 15 is started to extend and push the support plate 21 on the lifting component 2 to move vertically upward on the heavy-duty AGV trolley 1. The upward-moving support plate 21 pulls the support arm 13 to deflect and extend, so that the two ends of the support arm 13 deflect on the bottom surface of the support plate 21 and the sliding block 12 respectively, reaching a suitable installation height for the steel coil. Then, the double-headed hydraulic rod 16 is started to extend and drive the pin 17 to slide horizontally. The pin 17 is inserted through the locking holes 14 on both sides of the rod frame 11. In the insertion hole, the sliding block 12 is limited to slide on the rod 11, thereby limiting the height of the lifting component 2 supporting the steel coil installation. Then, the steel coil is installed on the uncoiler, thus completing the steel coil installation of the uncoiler. During use, the support roller 3 is used to support the steel coil. The journal 32 at the center of both ends of the support roller 3 is threaded into the threaded groove 31 at the center of both ends of the support roller 3 through the threaded shaft 33 at the end of the journal 32. The journal 32 can be detachably assembled with the support roller 3. If the journal 32 is damaged during use, the journal 32 and the support roller 3 can be disassembled and the journal 32 can be replaced. Thus, the roller body of the support roller 3 does not need to be discarded as a whole. By disassembling the journal 32 and the support roller 3 and replacing the journal 32, the support roller 3 can be quickly reused.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
