[0049] The utility model provides a kind of reel-shaped material transfer mechanism and reel-shaped material transfer car.

[0050] Please refer to Figures 1 to 5 In the utility model one embodiment, the reel-shaped material transfer mechanism 10, the central position of reel-shaped material is formed with cavity, reel-shaped material transfer mechanism 10 includes base 100, steering assembly 200 and bearing component 300, and the mounting site is formed on base 100, steering assembly 200 is installed in the mounting site, and steering assembly 200 is formed rotating end along the first direction with the end of steering assembly 200 away from base 100, bearing component 300 includes the connecting beam 310 of extension along second direction and the bearing assembly 320 of extension along third direction, one end of connecting beam 310 and bearing assembly 320 is connected, and bearing assembly 320 can be inserted into the cavity of reel-shaped material 40 and expand to the side wall of cavity and be tightly closed;Steering assembly 200 can be separated from connecting beam 310 when bearing assembly 320 expands to the side wall of cavity and be tightly closed, and connecting beam 310 can drive bearing assembly 320 to rotate, to make reel-shaped material that is tightly matched with bearing assembly 320 parallel to ground.

[0051] In one embodiment, the present application provides a reel-shaped material transfer mechanism 10, for solving when reel-shaped material is handled, due to the risk of reel-shaped material rolling, reel-shaped material is prone to rolling from transfer equipment such as forklift, and the technical problem of affecting handling efficiency.

[0052] The reel-shaped material transfer mechanism 10 includes base 100, steering assembly 200 and bearing component 300. The mounting site is formed on base 100, and steering assembly 200 is installed in the mounting site. Steering assembly 200 extends along the first direction, so that the end of steering assembly 200 away from base 100 forms a rotating end. Bearing component 300 includes a connecting beam 310 extending along a second direction and a bearing assembly 320 extending along a third direction. One end of connecting beam 310 and bearing assembly 320 is connected. It should be noted that in this embodiment, the first direction is an example of an upwardly inclined direction, the second direction is an example of a horizontal direction, and the third direction is an example of a vertical direction.

[0053] The central position of the reel-shaped material in the present application is formed with a cavity. Bearing assembly 320 can be inserted into the cavity and expanded to the side wall of the cavity. So that bearing assembly 320 can stably support reel-shaped material, prevent reel-shaped material from rolling during transfer.

[0054] The turning assembly 200 has an important feature: when the bearing assembly 320 is inflated to tightly abut the side wall of the cavity, the turning assembly 200 can be detached from the connecting beam 310. This allows the connecting beam 310 to drive the bearing assembly 320 to rotate, so that the cylindrical material abutting the bearing assembly 320 is parallel to the ground.

[0055] The specific implementation process is as follows: first, insert the bearing assembly 320 into the cavity of the cylindrical material. Then, inflate the bearing assembly 320 through some inflation mechanism (such as pneumatic or mechanical inflation device) until it tightly abuts the side wall of the cavity.

[0056] Next, the turning assembly 200 is detached from the connecting beam 310, allowing the connecting beam 310 to freely rotate. The purpose of rotation is to make the cylindrical material parallel to the ground. There are several important benefits to posture adjustment: first, it significantly reduces the risk of rolling of the cylindrical material, because the axis of the cylindrical material is perpendicular to the ground at this time; second, it facilitates subsequent handling and storage operations, improving overall operational efficiency; finally, the horizontal placement method is also beneficial to protect the quality of the cylindrical material and reduce the risk of deformation or damage caused by improper posture.

[0057] Through the above structure and operation process, the cylindrical material transfer mechanism 10 of the present application effectively solves the problem of possible rolling of the cylindrical material during handling. The inflation feature of the bearing assembly 320 ensures that the cylindrical material is securely fixed, and the cooperation of the turning assembly 200 and the connecting beam 310 realizes the flexible adjustment of the posture of the cylindrical material. Not only improves the safety and efficiency of handling, but also is beneficial to the long-term preservation and subsequent use of the cylindrical material.

[0058] The cylindrical material transfer mechanism 10 provided by the present application successfully solves the problem of rolling risk during the handling of cylindrical material through its unique structural design and operation method. The mechanism not only can stably support and fix the cylindrical material, but also can flexibly adjust the posture of the cylindrical material to make it parallel to the ground. It improves the safety and efficiency of handling the cylindrical material, and brings substantial improvement to the production and operation process of related industries.

[0059] In the embodiment, by setting the base 100, the steering assembly 200 and the bearing component 300, in use, the steering assembly 200 is installed on the mounting position formed on the base 100, and the steering assembly 200 is formed with a rotating end away from the base 100 along a first direction, the bearing component 300 includes a connecting beam 310 extending along a second direction and a bearing assembly 320 extending along a third direction, the connecting beam 310 is connected with one end of the bearing assembly 320, and the bearing assembly 320 can be inserted into the cavity and expanded to abut against the side wall of the cavity; so that the utility model can make the steering assembly 200 can be separated from the connecting beam 310 when the bearing assembly 320 is expanded to abut against the side wall of the cavity of the reel-shaped material, and the connecting beam 310 can drive the bearing assembly 320 to rotate, so that the reel-shaped material abutting against the bearing assembly 320 is parallel to the ground, thereby the utility model can abut against the reel-shaped material in the mode of abutting against the inner wall of the cavity formed on the reel-shaped material, so that the reel-shaped material will not roll again, and the reel-shaped material can be transported without using clamping jaws and other equipment, the transport stability of the reel-shaped material is improved, and the transport efficiency of the reel-shaped material is ensured.

[0060] In an embodiment, the bearing assembly 320 includes an outer sleeve 321, a driving member 324 and a plurality of expansion blocks 323, one end of the outer sleeve 321 is connected with the connecting beam 310 away from the connecting beam 310, the outer sleeve 321 can be inserted into the cavity, a plurality of through holes 322 are formed on the outer sleeve 321 and are distributed along the circumference of the outer sleeve 321, the number of the expansion blocks 323 is consistent with that of the through holes 322 and each expansion block 323 is in sliding fit with a corresponding through hole 322, and the driving member 324 is installed in the outer sleeve 321 and can synchronously drive all the expansion blocks 323 to extend out of the outer sleeve 321 from the corresponding through holes 322 and abut against the side wall of the cavity.

[0061] Specifically, the outer sleeve 321 serves as the main structure of the bearing assembly 320, one end of the outer sleeve 321 is connected with the connecting beam 310, and the other end can be freely inserted into the central cavity of the reel-shaped material. The plurality of through holes 322 uniformly distributed on the outer sleeve 321 provide sliding channels for the expansion blocks 323. Each expansion block 323 corresponds to a through hole 322 and can slide in the through hole 322. This allows the expansion blocks 323 to extend out of the surface of the outer sleeve 321 when needed, achieving close contact with the side wall of the cavity of the reel-shaped material.

[0062] The driving member 324 is installed inside the outer sleeve 321 and is the core component of the entire expansion mechanism. It can synchronously drive all the expansion blocks 323, ensuring that the expansion blocks 323 uniformly extend out of the through holes 322. The synchronous driving mode ensures that the contact pressure between the bearing assembly 320 and the cavity of the reel-shaped material is uniformly distributed, avoiding the deformation or damage of the reel-shaped material caused by excessive local stress.

[0063] The operator or automated device inserts the outer sleeve 321 into the center cavity of the log material. After insertion is complete, the drive 324 is activated. The drive 324 can be a hydraulic, pneumatic, or electric mechanism capable of generating an outward pushing force. The pushing force is applied to all expansion blocks 323 simultaneously through a linkage or cam mechanism. Under the action of the drive 324, the expansion blocks 323 are synchronously slid out of the through holes 322 until they are in close contact with the side walls of the log material cavity.

[0064] In this embodiment, the use of multiple expansion blocks 323 increases the contact area with the log material, improving the stability of the fixation. Secondly, the synchronous movement of the expansion blocks 323 ensures that the log material is uniformly stressed, reducing the risk of deformation of the log material. Thirdly, by adjusting the force of the drive 324, the extent to which the expansion blocks 323 extend can be precisely controlled, adapting to log materials of different sizes. Finally, the telescopic structure facilitates the installation and disassembly of the log material.

[0065] In this embodiment, not only can it adapt to log materials of different sizes, but also ensure that the log material is uniformly stressed during fixation and rotation, greatly reducing the risk of log material rolling or damage. At the same time, it is also convenient for operation and maintenance, improving the efficiency and safety of the entire log material transfer process.

[0066] In an embodiment, the through hole 322 is formed as a waist-shaped hole extending along the extension direction of the outer sleeve 321, and the expansion block 323 is adapted in shape to the through hole 322.

[0067] Specifically, the waist-shaped hole is a long strip-shaped hole with its long axis direction consistent with the extension direction of the outer sleeve 321. Such a shaped through hole 322 provides more space for the expansion block 323 to move. Compared with a circular or square through hole 322, the waist-shaped hole allows the expansion block 323 to have a larger range of movement in the axial direction of the outer sleeve 321. This design has several significant advantages:

[0068] Firstly, the waist-shaped hole increases the contact area of the expansion block 323 with the side walls of the cavity of the log material. When the expansion block 323 extends out of the through hole 322, it can cover a longer axial distance, thus providing more stable support. This increased contact area helps to more evenly distribute the pressure, reducing the risk of deformation or damage to the log material.

[0069] Secondly, the design of the waist-shaped hole increases the adaptability of the system. Since the reel-shaped material may have slight size deviations during the manufacturing process or may deform slightly during use, the waist-shaped hole allows the expansion block 323 to have certain adjustment space in the axial direction. This enables the reel-shaped material carrying assembly 320 to better adapt to reel-shaped materials in different states, ensuring the consistency of the fixing effect.

[0070] Furthermore, the design of the waist-shaped hole is also conducive to the installation and maintenance of the expansion block 323. Compared with other shapes of through holes 322, the waist-shaped hole provides more fault-tolerant space for the installation of the expansion block 323, making the assembly process more convenient. At the same time, if the expansion block 323 needs to be replaced or repaired, the waist-shaped hole also facilitates the relevant work of the operator.

[0071] The shape adaptation of the expansion block 323 to the through hole 322 means that the expansion block 323 also presents a long strip shape matching the waist-shaped hole. This ensures the stable sliding of the expansion block 323 in the through hole 322, avoiding jamming or skewing during movement. At the same time, shape adaptation also maximizes the effective surface area of the expansion block 323, enabling it to more effectively contact the side wall of the reel-shaped material cavity.

[0072] In actual operation, when the driving member 324 is activated, the expansion block 323 slides out along the waist-shaped hole. Since the waist-shaped hole provides a longer axial space, the expansion block 323 can adjust its extension within a larger range to adapt to reel-shaped material cavities of different diameters. This enables the reel-shaped material carrying assembly 320 to be applicable to reel-shaped materials of various specifications, increasing the versatility of the equipment.

[0073] The waist-shaped design of the through hole 322 and the shape adaptation of the expansion block 323 greatly improve the performance and applicability of the carrying assembly 320. Not only does it increase the contact area with the reel-shaped material, improving the stability of the fixing, but it also enhances the adaptability of the system to changes in the size of the reel-shaped material. At the same time, it also simplifies the assembly and maintenance process, improving the overall convenience of operation.

[0074] In an embodiment, the part of each expansion block 323 located in the cavity and arranged in a waist shape is formed with an extrusion groove 325 arranged in a tapering manner towards one end of the connecting beam 310. The driving member 324 can move in the outer sleeve 321 along the extrusion groove 325 to make the expansion block 323 extend out of the outer sleeve 321 from the corresponding through hole 322 and abut against the side wall of the cavity.

[0075] Specifically, each expansion block 323 forms a special extrusion slot 325 at the part of it located inside the cavity. The extrusion slot 325 is characterized by a tapered shape towards the end connected with the connecting beam 310. The tapered structure means that the width or depth of the extrusion slot 325 gradually decreases from the end far away from the connecting beam 310 to the end close to the connecting beam 310. The tapered structure provides a guiding and force-adding channel for the movement of the driving member 324.

[0076] The driving member 324 is installed inside the outer sleeve 321 and can move along the direction of the extrusion slot 325. When the driving member 324 is activated, it will move along the extrusion slot 325. Due to the tapered setting of the extrusion slot 325, the driving member 324 will generate a gradually increasing lateral force on the expansion block 323 during the movement. This enables the expansion block 323 to smoothly extend out of the outer sleeve 321 from the corresponding through hole 322.

[0077] The outer sleeve 321 is inserted into the cavity of the roll-shaped material. At this time, the expansion block 323 is in a contracted state and is completely located in the through hole 322. When it is necessary to fix the roll-shaped material, the driving member 324 starts to move along the extrusion slot 325. As the driving member 324 advances in the tapered extrusion slot 325, the lateral force exerted on the expansion block 323 gradually increases.

[0078] In this embodiment, the tapered extrusion slot 325 provides a smooth force transmission process. This avoids the sudden force on the expansion block 323 that may cause impact or damage to the roll-shaped material. The smooth extension process ensures that the roll-shaped material is uniformly stressed, reducing the risk of local stress concentration. The tapered structure allows the driving member 324 to gradually increase the force during movement. This means that in the initial stage, the expansion block 323 can slowly extend with a smaller force, while in the later stage, it can provide a larger force to ensure close contact with the side wall of the roll-shaped material cavity. By controlling the position of the driving member 324 in the extrusion slot 325, the degree of extension of the expansion block 323 can be accurately adjusted. This allows the operator or automatic control system to make fine adjustments according to the characteristics of different roll-shaped materials, improving the adaptability and accuracy of the device. With the tapered setting of the extrusion slot 325, when the driving member 324 moves in the opposite direction, the expansion block 323 will naturally retract under the action of its own gravity and the elastic force of the roll-shaped material. This simplifies the retraction process, eliminates the need for additional retraction mechanisms, and improves the reliability and simplicity of the entire system.

[0079] In this embodiment, not only can the expansion block 323 smoothly extend and retract, but also precise force control can be provided to adapt to roll-shaped materials of different specifications. This further improves the performance and reliability of the roll-shaped material transfer mechanism 10, providing more perfect technical support for solving the rolling risk of roll-shaped materials during handling.

[0080] In an embodiment, the outer sleeve 321 has a sealing block 326 at each end, and the sealing block 326 has a concentric threaded hole. The drive member 324 includes a screw rod 3241, a drive hand wheel 3242, and an extrusion platform 3243. The screw rod 3241 is arranged in the cavity, and the screw rod 3241 is screwed with the threaded hole of the sealing block 326. The end of the screw rod 3241 close to the connecting beam 310 extends out of the cavity along the extension direction of the outer sleeve 321 to form a drive end. The drive hand wheel 3242 is installed on the drive end and is in interference fit with the drive end. The extrusion platform 3243 is matched with the extrusion groove 325 and can be accommodated in the extrusion groove 325. The extrusion platform 3243 is in interference fit with the outer wall of the screw rod 3241. The drive hand wheel 3242 can drive the screw rod 3241 to move the extrusion platform 3243, so that the extrusion platform 3243 can move in the direction close to the drive hand wheel 3242 and make the expansion block extend out of the outer sleeve 321 from the corresponding through hole 322 and abut against the side wall of the cavity.

[0081] Specifically, the sealing block 326 at both ends of the outer sleeve 321 plays a sealing and supporting role, and at the same time provides a fixed point for the screw rod 3241. The concentric threaded hole on the sealing block 326 ensures that the screw rod 3241 maintains good centering during movement, reducing vibration and wear that may be caused by eccentric movement.

[0082] The screw rod 3241 is the core component of the drive member 324 and penetrates through the entire cavity. The screw rod 3241 is in threaded fit with the threaded hole on the sealing block 326, so that the screw rod 3241 can produce axial movement when rotating to provide driving force for the extrusion platform 3243. The end of the screw rod 3241 extends out of the cavity to form a drive end, so that the operator can control the movement of the screw rod 3241 externally.

[0083] The drive hand wheel 3242 is installed on the drive end of the screw rod 3241 and is in interference fit with it. The interference fit ensures that the drive hand wheel 3242 and the screw rod 3241 do not slide relative to each other, ensuring reliable transmission of the rotation force. The operator can accurately control the rotation angle and speed of the screw rod 3241 by rotating the drive hand wheel 3242.

[0084] The extrusion platform 3243 is a structure matched with the extrusion groove 325 and can be completely accommodated in the extrusion groove 325. The interference fit between the extrusion platform 3243 and the outer wall of the screw rod 3241 ensures synchronous movement between them, avoiding possible relative sliding during operation.

[0085] The operator rotates the drive hand wheel 3242, which drives the screw rod 3241 to rotate. Due to the threaded cooperation between the screw rod 3241 and the sealing block 326, the rotation of the screw rod 3241 is converted into axial movement. The axial movement is transmitted to the extrusion table 3243 through the interference fit, causing the extrusion table 3243 to move in the extrusion groove 325 towards the drive hand wheel 3242.

[0086] As the extrusion table 3243 moves in the extrusion groove 325, a lateral force is applied to the expansion block 323. Due to the tapered arrangement of the extrusion groove 325, the movement of the extrusion table 3243 causes the expansion block 323 to gradually extend from the through hole 322. Finally, the expansion block 323 is in close contact with the side wall of the cavity of the roll-shaped material, achieving the fixation of the roll-shaped material.

[0087] Through the combination of the screw rod 3241 and the drive hand wheel 3242, precise force control is achieved. The operator can accurately control the degree of extension of the expansion block 323 by adjusting the rotation angle of the drive hand wheel 3242, thereby adapting to roll-shaped materials of different sizes. The screw rod 3241 has a self-locking feature, and the expansion block 323 will remain in the current position without external force. It improves the reliability and stability of the roll-shaped material fixation. Simplifies the operation process. The operator only needs to rotate the drive hand wheel 3242 to complete the fixation and release of the roll-shaped material, without complex operation steps. All driving parts 324 are enclosed in the outer sleeve 321, reducing the influence of the external environment on the mechanism, improving the overall durability and reliability.

[0088] In this embodiment, the driving mechanism based on the screw rod 3241, the drive hand wheel 3242 and the extrusion table 3243 is adopted, providing a precise, reliable and easy-to-operate fixation method for the roll-shaped material transfer device. Not only can it adapt to roll-shaped materials of different specifications, but also can ensure the smoothness and controllability of the fixation process. Further improve the performance and practicality of the roll-shaped material transfer mechanism 10, and provide more perfect and reliable technical support for solving the rolling risk of roll-shaped materials during handling.

[0089] In an embodiment, the driving part 324 further comprises a limiting ring 3244, which is in interference fit with the outer wall of the screw rod 3241, and the limiting ring 3244 can slide along the inner wall of the outer sleeve 321, and the limiting ring 3244 is formed with a plurality of avoiding grooves 3245 corresponding to the number of expansion blocks 323.

[0090] Specifically, the limiting ring 3244 is an important component of the drive member 324, and its main function is to control and guide the movement of the expansion block 323. The limiting ring 3244 is in interference fit with the outer wall of the screw 3241, which ensures that the limiting ring 3244 can move with the rotation of the screw 3241, while not sliding on the surface of the screw 3241. This ensures the movement accuracy and reliability of the limiting ring 3244.

[0091] The limiting ring 3244 can slide along the inner wall of the outer sleeve 321, which allows the limiting ring 3244 to move axially when the screw 3241 rotates. The sliding fit between the limiting ring 3244 and the inner wall of the outer sleeve 321 not only ensures smooth movement, but also provides the necessary guiding effect, reducing the possibility of eccentricity or vibration during movement.

[0092] The limiting ring 3244 is formed with a number of avoidance grooves 3245 corresponding to the number of expansion blocks 323, which has multiple effects. First, the avoidance grooves 3245 provide movement space for the expansion blocks 323, allowing the expansion blocks 323 to remain relatively stationary when the limiting ring 3244 moves. Second, the presence of the avoidance grooves 3245 allows the limiting ring 3244 to move freely without interfering with the expansion blocks 323, avoiding the possibility of jamming or wear.

[0093] When the drive hand wheel 3242 is turned, the screw 3241 begins to rotate. Since the limiting ring 3244 is in interference fit with the screw 3241, the limiting ring 3244 will move with the screw 3241. In this process, the limiting ring 3244 slides along the inner wall of the outer sleeve 321, maintaining good centering effect. As the limiting ring 3244 moves, the avoidance grooves 3245 on it will gradually align with the expansion blocks 323. When the avoidance grooves 3245 are completely aligned with the expansion blocks 323, the expansion blocks 323 can extend from the through hole 322 and contact the side wall of the drum-shaped material cavity without being disturbed by the limiting ring 3244.

[0094] The presence of the limiting ring 3244 provides additional guidance and support. Not only guides the movement of the expansion block 323, but also can prevent the eccentricity or bending of the screw 3241 during rotation, improves the stability and accuracy of the whole mechanism. The design of the avoidance groove 3245 makes the movement of the expansion block 323 more flexible and controllable. The operator can accurately adjust the degree of extension of the expansion block 323 by controlling the position of the limiting ring 3244, so as to adapt to different sizes of the roll-shaped material. Simplify the contraction process of the expansion block 323. When it is necessary to release the roll-shaped material, only need to reverse rotate the screw 3241, the limiting ring 3244 will retreat, and the avoidance groove 3245 on it will push the expansion block 323 back to the initial position, without additional reset mechanism. The presence of the limiting ring 3244 also plays a protective role. It can prevent external impurities from entering the internal mechanism, prolonging the service life of the whole device.

[0095] In this embodiment, the structure of the driving part 324 containing the limiting ring 3244 further optimizes the performance of the roll-shaped material transfer mechanism 10. Through the cooperation of the limiting ring 3244 and the screw 3241, and the design of the avoidance groove 3245 on the limiting ring 3244, the precise control and protection of the movement of the expansion block 323 are realized. Not only improves the accuracy and reliability of the fixation of the roll-shaped material, but also simplifies the operation process and enhances the durability of the whole mechanism.

[0096] In an embodiment, the extrusion groove 325 has multiple, multiple extrusion grooves 325 are distributed along the extension direction of the outer sleeve 321, and the number of extrusion platforms 3243 is consistent with the number of extrusion grooves 325 and is set one by one.

[0097] Specifically, the outer sleeve 321 is provided with multiple extrusion grooves 325, and the multiple extrusion grooves 325 are distributed in a spaced distribution state along the extension direction of the outer sleeve 321. Each extrusion groove 325 corresponds to an extrusion platform 3243, forming a one-to-one configuration relationship.

[0098] The arrangement of multiple extrusion grooves 325 increases the contact area of the whole bearing assembly 320. The multiple extrusion grooves 325 distributed along the extension direction of the outer sleeve 321 can provide more support points in the axial direction of the roll-shaped material, which helps to more evenly distribute the pressure and reduce the possibility of local deformation or damage of the roll-shaped material during fixation. The one-to-one correspondence relationship between the extrusion groove 325 and the extrusion platform 3243 ensures that each extrusion platform 3243 can move independently. This allows the system to more accurately control the position and pressure of each extrusion platform 3243, thereby adapting to the possible minor shape differences or irregularities of the roll-shaped material.

[0099] When the driving member 324 (such as the screw 3241) starts to move, all the extrusion platforms 3243 will be driven at the same time. Each extrusion platform 3243 moves in its corresponding extrusion groove 325, pushing the corresponding expansion block 323 outward. Since the extrusion grooves 325 are spaced along the extension direction of the outer sleeve 321, this movement will cause the expansion blocks 323 to extend out at different axial positions of the drum-shaped material at the same time, and contact the inner wall of the drum-shaped material.

[0100] In this embodiment, the design of multiple extrusion grooves 325 and multiple extrusion platforms 3243 further optimizes the performance of the drum-shaped material transfer mechanism 10. By increasing the contact points, improving the fixing stability, achieving uniform stress and enhancing the adaptability, the risk of rolling of the drum-shaped material during the transfer process is effectively solved. At the same time, it also improves the operation precision and reliability of the whole system, and provides more comprehensive and efficient technical support for the transfer of drum-shaped materials of different specifications and states.

[0101] In an embodiment, each expansion block 323 is provided with a reset member 327, which is connected with the inner wall of the outer sleeve 321, and the reset member 327 can make the corresponding expansion block 323 separate from the side wall of the cavity and retract into the corresponding through hole 322.

[0102] Specifically, the reset member 327 is an important component of the drum-shaped material bearing assembly 320, and its main function is to ensure that the expansion block 323 can automatically return to the initial position when not needed. Each expansion block 323 is equipped with a reset member 327, which is connected with the inner wall of the outer sleeve 321, forming an automatic reset system.

[0103] The reset member 327 can be a spring, elastic rubber or other materials with elastic properties. When the expansion block 323 is in the extended state, the reset member 327 is in a compressed or stretched state, storing potential energy. Once the driving force is removed, the reset member 327 releases this potential energy, pushing or pulling the expansion block 323 back to the initial position.

[0104] When the drum-shaped material needs to be fixed, the driving member 324 (such as the screw 3241 and the extrusion platform 3243) pushes the expansion block 323 to extend out of the through hole 322 and contact the side wall of the cavity of the drum-shaped material; the reset member 327 is compressed or stretched and in the energy storage state. When the drum-shaped material needs to be released, the driving member 324 moves in the opposite direction, reducing the pushing force on the expansion block 323; the elastic force of the reset member 327 begins to act, pushing the expansion block 323 away from the side wall of the cavity and pulling it back into the through hole 322.

[0105] In this embodiment, the reset member 327 is provided, so that the embodiment has the following advantages in specific implementation: the presence of the reset member 327 enables the expansion block 323 to automatically return to the initial position without additional manual operation or complex control system. The release process of the roll-shaped material is simplified, and the operation efficiency is improved. Even in the case of drive system failure, the reset member 327 can ensure that the expansion block 323 returns to the safe position, preventing the roll-shaped material from being accidentally fixed or damaged. The reset member 327 can reduce the friction and impact between the expansion block 323 and the through hole 322, reducing the wear of the components and prolonging the service life of the entire device. The elastic force of the reset member 327 can balance the driving force, allowing the operator to more finely control the position and pressure of the expansion block 323, and adapt to roll-shaped materials of different thicknesses and hardnesses. In extreme cases, if the expansion block 323 is stuck in the extended position for some reason, the continuous force of the reset member 327 can help it to escape from the stuck state, increasing the fault tolerance of the system.

[0106] In this embodiment, not only the reliability and efficiency of the roll-shaped material fixing and releasing process are ensured, but also the safety and durability of the entire system are improved. The automatic reset mechanism greatly simplifies the operation process, reduces the possibility of human error, and also provides greater flexibility for the adaptability of roll-shaped materials of different specifications. Through this improvement, the roll-shaped material transfer mechanism 10 provides more comprehensive and efficient technical support in solving the rolling risk problem in the roll-shaped material handling process.

[0107] In an embodiment, the turning assembly 200 includes a connecting member 210, a connecting sleeve 220, a driving rod 230, and a driving handle 240. One end of the connecting member 210 is connected to the base 100, and the connecting member 210 extends in a first direction. The connecting sleeve 220 is installed at the end of the connecting member 210 away from the base 100. The connecting beam 310 is rotatably clamped to one end of the connecting sleeve 220. The driving rod 230 is rotatably installed in the connecting sleeve 220. The driving rod 230 is threadedly connected with the connecting beam 310 and the connecting sleeve 220. The end of the driving rod 230 away from the connecting beam 310 extends out of the connecting sleeve 220 along the extension direction of the connecting sleeve 220. The driving handle 240 is installed at the end of the driving rod 230 extending out of the connecting sleeve 220. The driving handle 240 can drive the driving rod 230 to rotate and disengage the driving rod 230 from the connecting beam 310. When the driving rod 230 is disengaged from the connecting beam 310, the connecting beam 310 can drive the bearing assembly 320 to rotate, so that the roll-shaped material in abutting engagement with the bearing assembly 320 is parallel to the ground.

[0108] Specifically, the connecting piece 210 serves as the base structure of the steering assembly 200, and is connected to the base 100 at one end and extends in the first direction to provide stable support for the entire steering assembly 200. The connecting sleeve 220 is installed at the end of the connecting piece 210 away from the base 100, forming the core part of the steering assembly 200. The connecting beam 310 is rotatably clamped at one end of the connecting sleeve 220, so that the connecting beam 310 can freely rotate when needed.

[0109] The drive rod 230 is installed inside the connecting sleeve 220 and can freely rotate inside the connecting sleeve 220. The drive rod 230 is connected to the connecting beam 310 and the connecting sleeve 220 in a threaded manner. Not only does it provide stable connection, but it also makes subsequent disconnection possible. One end of the drive rod 230 extends out of the connecting sleeve 220, and this extended part provides a position for installing the drive handle 240.

[0110] The drive handle 240 is installed at the end of the drive rod 230 extending out of the connecting sleeve 220. This position is convenient for the operator to operate and control the rotation of the drive rod 230.

[0111] When it is necessary to adjust the posture of the roll-shaped material, the operator drives the drive rod 230 to rotate by rotating the drive handle 240. Since the drive rod 230 is threaded with the connecting beam 310 and the connecting sleeve 220, the rotation of the drive rod 230 will cause it to gradually disengage from the connecting beam 310. When the drive rod 230 is completely disengaged from the connecting beam 310, the connecting beam 310 gains the ability to freely rotate.

[0112] At this time, the connecting beam 310 can drive the carrying assembly 320 to rotate. Through appropriate rotation, the roll-shaped material in close contact with the carrying assembly 320 can be made parallel to the ground.

[0113] In this embodiment, through the threaded disengagement of the drive rod 230 and the free rotation of the connecting beam 310, the smooth transition of the roll-shaped material from the vertical state to the horizontal state is realized. Not only can it effectively prevent the rolling risk of the roll-shaped material during transportation, but also it improves the efficiency and safety of the entire transportation process, providing an innovative and practical technical solution to solve the problem of roll-shaped material transportation.

[0114] In an embodiment, a plurality of bolt holes 110 are arranged on the base 100.

[0115] In this embodiment, by arranging a plurality of bolt holes 110, the base 100 can be detachably connected with an external roll-shaped material transport vehicle during use, realizing the function of replacement.

[0116] In an embodiment, the base 100 is formed with a clamping groove 120 close to one end of the steering assembly 200, and a protective piece is installed in the clamping groove 120.

[0117] In the embodiment, the clamping groove 120 is arranged, and the protective piece is installed in the clamping groove 120, so that the whole drum-shaped material transfer mechanism 10 can be protected, and the safety is improved.

[0118] Based on the same technical concept, the second aspect of the utility model further provides a drum-shaped material transfer vehicle, which comprises the drum-shaped material transfer mechanism 10, the walking mechanism 20 and the lifting movement mechanism 30 of the first aspect, the walking mechanism 20 can be switched between a walking state and a stationary state, a guide column extending vertically upward is arranged on the top of the walking mechanism, a slide extending vertically is formed on the guide column, the lifting movement mechanism 30 is slidably installed on the slide, and the lifting movement mechanism 30 can slide vertically in the slide, the drum-shaped material transfer mechanism is installed on the lifting movement mechanism, and the lifting movement mechanism can drive the drum-shaped material transfer mechanism to ascend and descend along the guide column.

[0119] Specifically, the walking mechanism 20 can be switched between a walking state and a stationary state. The switchable feature enables the drum-shaped material transfer vehicle to walk flexibly when moving is needed, and to remain stable when fixing is needed. The walking mechanism 20 can adopt a wheel structure and be equipped with a brake device to realize the switching of states.

[0120] A guide column extending vertically upward is arranged on the top of the walking mechanism. The guide column plays a supporting and guiding role, and provides a stable movement track for the lifting movement mechanism 30. A slide extending vertically is formed on the guide column, and the slide structure ensures the accuracy and stability of the lifting movement.

[0121] The lifting movement mechanism 30 is slidably installed on the slide and can slide vertically in the slide. The lifting movement mechanism 30 can move freely in the vertical direction to adapt to different operation requirements of different heights. The lifting movement mechanism 30 can adopt a hydraulic or electric driving mode to ensure the stability and controllability of the lifting process.

[0122] The drum-shaped material transfer mechanism is installed on the lifting movement mechanism. This enables the drum-shaped material transfer mechanism to move with the lifting movement mechanism, thereby realizing flexible carrying of the drum-shaped material. The lifting movement mechanism can drive the drum-shaped material transfer mechanism to ascend and descend along the guide column, so that the drum-shaped material transfer vehicle can adapt to different carrying requirements of different heights, such as carrying from the ground to a workbench or carrying from one height to another height.

[0123] The operator moves the reel-shaped material transfer trolley to the designated position and switches the walking mechanism 20 to the stationary state. Then, by controlling the lifting motion mechanism 30, the height of the reel-shaped material transfer mechanism is adjusted to match the height of the reel-shaped material to be carried. Next, the reel-shaped material transfer mechanism performs the reel-shaped material fixing process of the first aspect, firmly fixing the reel-shaped material on the carrying mechanism. After the fixing is completed, the operator can adjust the height of the lifting motion mechanism 30 again, lifting the reel-shaped material to the appropriate height, and then switch the walking mechanism 20 to the walking state, starting the carrying process.

[0124] The reel-shaped material carrying trolley exemplified in this embodiment has the following advantages: the lifting motion mechanism 30 enables the reel-shaped material transfer mechanism to adapt to different height operating environments, improving the flexibility and applicability of carrying. The design of the guide column and the slide ensures the stability of the lifting process, reducing the risk of reel-shaped material shaking during carrying. The switchable feature of the walking mechanism 20 enables the reel-shaped material transfer trolley to respond flexibly in different working stages, improving work efficiency. The combination of the reel-shaped material transfer mechanism and the lifting motion mechanism 30 enables the reel-shaped material to be in a controlled state throughout the carrying process, greatly reducing the risk of rolling.

[0125] In this embodiment, the reel-shaped material transfer trolley integrates the reel-shaped material transfer mechanism 10, the walking mechanism 20 and the lifting motion mechanism 30, forming a comprehensive reel-shaped material carrying solution. Not only can it firmly fix the reel-shaped material, but also can carry it flexibly between different heights and positions, effectively solving the problem of reel-shaped material rolling during carrying. It significantly improves the safety and efficiency of reel-shaped material carrying, and brings substantial improvement to the production and operation process of related industries.
