[0002] A straightening machine is used to straighten metal profiles, bars, pipes, wires, etc. Replacing the lower roller of a straightening machine is usually relatively simple, but replacing the upper roller is more difficult because it is unsupported after the bolts are removed. Without a roller changing device, an overhead crane is needed to lift the straightening roller, while a hand-operated hoist is used to assist in adjusting the direction. This greatly tests the experience and skills of the workers, consumes a lot of time, and carries the risk of the straightening roller going out of control and damaging the equipment.
[0003] Accordingly, there is a need in the art for a new straightening roller hoisting device to solve the above-mentioned technical problems. Utility Model Content
[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem of difficulty in hoisting existing straightening rollers.
[0005] This utility model provides a straightening roller hoisting device, characterized in that the hoisting device includes a hoisting part, a connecting part, a supporting part, and a pallet assembly, wherein:
[0006] The hoisting part extends along a first direction, and the connecting part extends along a second direction, the first direction being perpendicular to the second direction. One end of the hoisting part is connected to one end of the connecting part to form an L-shape.
[0007] The support part is connected to the connecting part, and a locking mechanism is provided between the support part and the connecting part. When the support part is in the working state, the locking mechanism is in the locked state to lock the relative position between the support part and the connecting part. The support part extends along the first direction and is arranged opposite to the hoisting part. The support part, the connecting part and the hoisting part cooperate with each other to form an inverted U-shaped structure with one side open, so that a first space for placing the upper roller of the straightening roller is formed between the hoisting part and the support part.
[0008] The tray assembly includes a mounting table turntable, a boss, and a positioning component. The support portion has a mounting table formed on the side facing the first space. The turntable is rotatably mounted on the mounting table via a rotating connection component, allowing the turntable to rotate and adjust along a first direction as its axis. The boss is mounted on the mounting table turntable, and a positioning keyway is formed on the boss corresponding to the fixing position of the straightening roller to be installed. The positioning keyway cooperates with a fixing key to fix the boss to the straightening roller to be installed. The positioning component is used to control the rotation or locking of the turntable on the mounting table.
[0009] Based on the above configuration, the combination of the hoisting part, the connecting part and the supporting part forms an L-shaped and an inverted U-shaped structure. This design not only improves the structural strength and stability of the device, but also provides a primary space for placing the straightening roller, which facilitates the stable support and placement of the roller.

The lower support is installed on the top of the mounting platform, and the upper support is installed on the bottom of the turntable. The upper support and the lower support are rotatably connected by the bearing.
[0017] Based on the above configuration, by connecting the upper and lower supports with bearings, smooth rotation of the turntable is achieved, mechanical friction is reduced, and the service life of the device is extended. At the same time, this connection method improves operational flexibility and precision, and facilitates adjustment of the straightening roller's placement angle.
[0018] In the preferred embodiment of the above-mentioned straightening roller hoisting device, the bearing is configured as a thrust ball bearing.
[0019] Based on the above configuration, this type of bearing, with its excellent load-bearing capacity, is suitable for bearing axial loads, ensuring that the device can still rotate smoothly under large loads, effectively improving the safety and reliability of the device.
[0020] In the preferred embodiment of the above-mentioned straightening roller hoisting device, the fixing key is set as a T-shaped plate, the extended end of the T-shaped plate is inserted into the positioning keyway, and both sides of the T-shaped plate are fixedly installed on the boss by bolts.
[0021] Based on the above design, the T-shaped plate of the fixed key ensures a stable connection at the positioning keyway through plug-in and bolt installation. This design not only prevents the straightening roller from sliding and shifting, but also facilitates application in different installation scenarios.
[0022] In the preferred embodiment of the above-mentioned straightening roller hoisting device, the locking mechanism includes a first pin and a second pin. The lower end of the connecting part is provided with two first extension pieces, and a clamping space is formed between the two first extension pieces.

The first extension piece and the second extension piece are hinged through the first pin. The second pin is located above the first pin and on the side of the second extension piece facing the first space, so as to abut against the second extension piece rotating toward the first space.
[0023] Based on the above configuration, the use of the first and second pins, along with the insertion design of the two sets of extension plates, ensures that the relative positions of the support and the connecting part can be securely locked. This mechanism provides a safety guarantee when the support is not in use, during the transition from the working state to the operating state.
[0024] In the preferred embodiment of the above-mentioned straightening roller hoisting device, the connecting part and the hoisting part are an integral structure. The side cross-section of the integral structure is a 7-shaped structure, and the front cross-section of the integral structure is an I-shaped structure.

These are merely for ease of description and do not indicate or imply that the structure must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0036] This utility model provides a straightening roller hoisting device, characterized in that the hoisting device includes a hoisting part 1, a connecting part 2, a supporting part 3, and a pallet assembly, wherein:
[0037] The hoisting part 1 extends along a first direction, and the connecting part 2 extends along a second direction, which is perpendicular to the second direction. One end of the hoisting part 1 is connected to one end of the connecting part 2 to form an L-shape. Of course, this invention does not impose any restrictions on the connection structure between the hoisting part 1 and the connecting part 2. Those skilled in the art can design it according to their needs. For example, the connecting part 2 and the hoisting part 1 can be detachable, or they can be an integral structure, as long as the connection part 2 and the hoisting part 1 are sufficiently stable during operation. In this preferred embodiment, the connecting part 2 and the hoisting part 1 are an integral structure. The side cross-section of the integral structure is a 7-shaped structure, and the front cross-section is an I-shaped structure. Thirteen triangular supports are provided at the angled connection points within the integral structure. The integral structure improves the overall strength and durability of the device. The 7-shaped and I-shaped cross-section designs optimize the stress distribution and deformation resistance of the device, and the thirteen triangular supports at the angled connection points further enhance the stability of the device during operation. Of course, this utility model does not impose any restrictions on the specific structure of the 13 triangular supports. Those skilled in the art can set it according to their needs. For example, the 13 triangular supports can be plate-shaped structures, or rod-shaped structures, or other shapes besides triangles, as long as the 13 triangular supports can improve the stability of the hoisting part 1 and the connecting part 2.
[0038] The support part 3 is connected to the connecting part 2. A locking mechanism is provided between the support part 3 and the connecting part 2. When the support part 3 is in the working state, the locking mechanism is in the locked state to lock the relative position between the support part 3 and the connecting part 2. The support part 3 extends along the first direction and is arranged opposite to the hoisting part 1. The support part 3, the connecting part 2 and the hoisting part 1 cooperate to form an inverted U-shaped structure with one side open, so that a first space for placing the upper roller of the straightening roller is formed between the hoisting part 1 and the support part 3. It should be noted that the present invention does not impose any restrictions on the specific structure of the support part 3. Those skilled in the art can set it according to their needs. For example, the support part 3 can be a planar structure, or it can be a frame structure, as long as the structural strength of the support part 3 is sufficient to support the straightening roller.
[0039] The tray assembly includes a mounting platform 14, a turntable 4, a boss 5, and a positioning component. The mounting platform 14 is formed on the side of the support 3 facing the first space. The turntable 4 is rotatably mounted on the mounting platform 14 via a rotating connection component, allowing the turntable 4 to rotate and adjust along a first direction as its axis. The boss 5 is mounted on the turntable 4 of the mounting platform 14. A positioning keyway is formed on the boss 5 corresponding to the fixing position of the straightening roller to be installed. The positioning keyway cooperates with the fixing key to fix the boss 5 to the straightening roller to be installed. The positioning component is used to control the rotation or locking of the turntable 4 on the mounting platform 14. It should be noted that this invention does not impose any limitations on the specific structure of the positioning keyway and the fixing key. Those skilled in the art can set them according to their needs. For example, the positioning keyway and the fixing key can be a square keyway and a key, or a circular keyway and a key, as long as the positioning keyway and the fixing key can firmly fix the straightening roller to the boss 5. In this preferred embodiment, the fixing key is a T-shaped plate, the extended end of which inserts into the positioning keyway, and both sides of the T-shaped plate are fixedly mounted on the boss 5 by bolts. The T-shaped plate design of the fixing key, through insertion and bolt installation, ensures a stable connection at the positioning keyway. This design not only prevents the straightening roller from sliding and shifting but also facilitates application in different installation scenarios.
[0040] Of course, it should also be noted that this utility model does not impose any restrictions on the specific structure of the turntable 4. Those skilled in the art can set it according to their needs. For example, the turntable 4 can be a circular structure, or it can be a square structure, as long as the turntable 4 can accommodate the installation of the straightening roller.
[0041] The combination of the lifting part 1, the connecting part 2, and the supporting part 3 forms an L-shaped and inverted U-shaped structure. This design not only improves the structural strength and stability of the device but also provides a primary space for placing the straightening roller, facilitating stable support and placement of the roller. This layout allows the device to better withstand the load of the straightening roller and its operation, preventing accidental overturning.
[0042] Furthermore, the positioning component includes a first connecting block and a second connecting block. The first connecting block is disposed on the mounting platform 14, and the second connecting block is disposed on the turntable 4. When the turntable 4 is aligned with the mounting platform 14, the first connecting block and the second connecting block are in contact and fixed, thereby positioning the turntable 4 on the mounting platform 14. The positioning component achieves precise positioning of the turntable 4 through the alignment and contact fixation of the first connecting block and the second connecting block, ensuring the stability and accuracy of the rotation and locking of the turntable 4 on the mounting platform 14. This means that during operation, the straightening roller can remain in the designated position, improving the working efficiency and safety of the device. It should be noted that this utility model does not impose any limitations on the specific structure of the first connecting block and the second connecting block. Those skilled in the art can set it according to their needs. For example, the first connecting block and the second connecting block can be a snap-fit structure, or they can be a bolt-fixed structure, as long as the first connecting block and the second connecting block can control whether the turntable 4 is positioned. In this preferred embodiment, the first connecting block is a lower ear plate 6, and the second connecting block is an upper ear plate 7. The upper ear plate 7 and the lower ear plate 6 are fixedly connected by bolts. This design makes the connection between the ear plates more secure, and the bolt connection is also easy to install and disassemble, facilitating daily maintenance and repair. This detachable design helps to extend the service life of the equipment and reduce maintenance costs.
[0043] In a preferred embodiment, two sets of upper ear plates 7 and lower ear plates 6 are provided, with two upper ear plates 7 respectively located on both sides of the turntable 4; and two lower ear plates 6 respectively located on both sides of the mounting platform 14. This design provides stronger stability and support, better dispersing stress and vibration generated during operation, and reducing wear on the turntable 4 and the base. It should be noted that this invention does not impose any limitation on the specific number of upper ear plates 7 and lower ear plates 6 combinations. Those skilled in the art can set them according to their needs. For example, the upper ear plates 7 and lower ear plates 6 can be set as one set, or multiple sets, as long as, for example, the upper ear plates 7 and lower ear plates 6 combinations can stably fix the turntable 4 to the mounting platform 14.
[0044] Furthermore, the rotating connection assembly includes a lower support 8, a bearing 9, and an upper support 10. The lower support 8 is mounted on the top of the mounting platform 14, and the upper support 10 is mounted on the bottom of the turntable 4. The upper support 10 and the lower support 8 are rotatably connected by the bearing 9. By connecting the upper support 10 and the lower support 8 with the bearing 9, smooth rotation of the turntable 4 is achieved, mechanical friction is reduced, and the service life of the device is extended. At the same time, this connection method improves the flexibility and accuracy of operation and facilitates the adjustment of the placement angle of the straightening roller. Of course, this utility model does not impose any limitations on the specific structure of the upper support 10 and the lower support 8. Those skilled in the art can set it according to their needs. For example, the upper support 10 and the lower support 8 can also be annular shafts, or for example, the upper support 10 and the lower support 8 can also be cylindrical shafts, as long as the upper support 10 and the lower support 8 can rotate as required.
[0045] As a preferred embodiment, the bearing 9 is configured as a thrust ball bearing 9. This type of bearing 9 is suitable for bearing axial loads due to its good load-bearing capacity, ensuring that the device can still rotate smoothly under large loads, effectively improving the safety and reliability of the device.
[0046] Furthermore, the locking mechanism includes a first pin 11 and a second pin 12. Two first extension pieces are provided at the lower end of the connecting part 2, forming a clamping space between them. Two second extension pieces are provided at the end of the supporting part 3 near the connecting part 2. When the supporting part 3 is in the working state, the two extension pieces extend along a first direction and insert into the clamping space. The first and second extension pieces are hinged together by the first pin 11. The second pin 12 is located above the first pin 11, on the side of the second extension piece facing the first space, to prevent the second extension piece from rotating towards the first space. The use of the first pin 11 and the second pin 12, along with the insertion design of the two sets of extension pieces, ensures that the relative positions of the supporting part 3 and the connecting part 2 can be firmly locked. This mechanism provides a safety guarantee when the supporting part 3 is not in use, during the transition to the working state.
[0047] The lifting section 1 has multiple lifting holes, which provide operators with diverse lifting options to adapt to different working conditions. This flexibility reduces operational complexity and improves work efficiency and safety without incurring additional costs.
[0048] The technical solution of this utility model has been described in conjunction with the optional embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
