Description

Technical Field

[0001] This invention relates to the field of giant engineering tire production, specifically to a storage and transportation device for semi-finished giant engineering tires. Background Technology

[0002] In the production of giant engineering tires, the raw rubber tire blanks need to be separated from the support equipment and stored separately for a certain period of time, including production transportation between various processes and temporary storage during the production process. Currently, simple pallet trolleys are mostly used to carry the tire blanks. When the tire blanks need to be stored on the pallet trolley for a long time, the trolley needs to be parked in a specific position so that a hand-operated hoist can be set up above to lift the top of the tire blank and prevent the upper part of the tire blank from shifting downward under the action of gravity.

[0003] Because giant engineering tires are significantly heavier than ordinary tires, and the semi-finished tire blanks have not yet undergone vulcanization and shaping, prolonged localized lifting at the upper toe area, along with frequent lifting and disassembly between processes, inevitably leads to structural deformation or displacement of the rubber compound and steel wires, directly affecting the quality of the finished product after vulcanization and shaping. Current operating methods involve a significant amount of manual labor, resulting in high time consumption, low efficiency, and high labor costs, as well as safety hazards during operation within the workshop. Furthermore, existing transport vehicles rely solely on manual operation and cannot meet the company's need for upgraded management through AGV (Automated Guided Vehicle) material handling.

[0004] Furthermore, the simple pallet transport vehicles used in the current giant tire production process are no longer suitable for new technological requirements, such as the adoption of pre-carved pattern processes and tire blank internal cavity inspection and repair processes. During offline carving of the tire blank, internal cavity inspection and repair processes, and tire blank loading and alignment with the pattern mold, it is necessary to better maintain the internal and external structural shape of the tire blank. However, the existing tire blank support devices cannot prevent significant deformation of the tire blank, and repeated lifting operations directly affect the changes in the internal material structure of the tire blank. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides a multifunctional storage and transportation device for giant engineering tire blanks. This device can provide protective support for the tire blanks during transportation and also offers automated operation support. It is suitable for the needs of new processes in giant tire production and can lay a solid foundation for the realization of intelligent production AGV vehicle transportation scheduling.

[0006] The technical solution of the present invention is as follows:

[0007] A giant engineering tire blank storage and transportation device, characterized in that it includes a tire receiving assembly, a tire sidewall support mechanism, and a base assembly.

[0008] The tire receiving assembly is a hollow ring structure, which is set on the base assembly. It includes a tire receiving seat and a toe centering assembly. The tire receiving seat includes two hollow ring structures, an inner ring and an outer ring, which are connected as one piece. The upper surface of the outer ring is connected to the hollow disc-shaped tray above by a rib plate. The disc-shaped tray is adapted to the lower tire side profile of the tire carcass. The bottom surface of the outer ring is provided with multiple support plates evenly distributed around the circumference.

[0009] The toe-mouth alignment assembly is installed on the upper surface of the inner ring. The toe-mouth alignment assembly includes multiple toe-mouth blocks, a slide rail, a cam disc, and an alignment cylinder. Each toe-mouth block includes a bottom surface and a vertical arc surface. Multiple toe-mouth blocks are evenly distributed around the center of the tire seat to form a ring. The bottom of the vertical arc surface is located at the edge of the bottom surface near the center and is adapted to the inner side of the toe-mouth of the tire carcass. Each toe-mouth block is connected to the upper surface of the bottom plate of the inner ring through a slide rail. The alignment cylinder can drive the cam disc to rotate and drive the toe-mouth blocks to slide synchronously in the radial direction along the slide rail. When the vertical arc surface enters the inner side of the toe-mouth of the tire carcass, the multiple toe-mouth blocks move synchronously from the center outward under the drive of the alignment cylinder and the cam disc, forming a ring tightly against the inner side of the toe-mouth. At this time, the center of the ring structure of the toe-mouth block is the center of the toe-mouth of the tire carcass.

[0010] The base assembly includes a base frame, multiple steering cylinders, wheel seats, and wheels. The base frame includes an inner connecting groove and an outer support ring. The inner connecting groove is a hollow annular structure, including an annular bottom surface and a vertical sidewall located on the outer edge of the annular bottom surface. The inner side of the outer support ring is connected to the outer periphery of the sidewall. A sliding mechanism is installed on the outer periphery of the upper surface of the outer support ring, corresponding to the support plate of the tire receiving seat. The contact surface between the sliding mechanism and the support plate supports the tire receiving assembly, and the tire receiving assembly can move horizontally above the base assembly.

[0011] The multiple correction cylinders are evenly distributed around the center of the base frame on the surface of the outer support ring. The cylinder body is fixed radially to the outside of the side wall of the inner connecting groove. After the piston rod extends, it can push against the inner side of the outer wall of the inner ring of the tire receiving seat. By synchronously moving the correction cylinders, the outer wall of the inner ring of the tire receiving seat is pushed, so that the tire receiving seat moves horizontally above the base assembly, so that the center of the tire receiving assembly is consistent with the center of the base assembly.

[0012] The sidewall support mechanism includes drive cylinders, guide sleeves, and several support arm assemblies evenly distributed circumferentially. The guide sleeves are at least two-stage and can slide up and down sequentially. The bottom of the outermost sleeve is fixed to the center of the base frame of the base assembly. The top of the innermost sleeve is connected to the support arm assembly. An innermost flange is fixed to the inner side of the middle of the innermost sleeve. The guide sleeve has at least two-stage drive cylinders. The top of the second innermost piston is connected to the flange to drive the lifting and lowering movement of the innermost sleeve, thereby driving the lifting and lowering movement of the support arm assembly. The innermost piston drives the extension or retraction of the support arm assembly. The outer end of the support arm assembly is an arc-shaped support plate adapted to the shape of the inner wall of the tire sidewall.

[0013] Alternatively, the guide sleeve is a single stage with a single-stage drive cylinder inside. The innermost piston drives the extension or retraction of the support arm assembly, and the outer end of the support arm assembly is an arc-shaped support plate adapted to the shape of the inner wall of the tire sidewall.

[0014] In one embodiment, the guide sleeve is a single stage, and the support arm assembly is connected to the guide sleeve via an upper connecting seat and a lower connecting seat. The upper connecting seat is fixedly connected to the top end of the guide sleeve, and the upper end of the drive cylinder is fixed to the inner side of the guide sleeve. The lower connecting seat includes a transmission arm that passes through the interior of the guide sleeve through a long slot hole in the side wall. The slot hole is connected to the top end lug of the piston of the drive cylinder via a pin. Each support arm assembly consists of multiple support arms connected by short shafts to form a scissor-like structure. The ends of the two short shafts forming the innermost scissor are rotatably connected to the upper connecting seat and the lower connecting seat, respectively.

[0015] In another embodiment, the guide sleeve has at least two stages. The support arm assembly is connected to the innermost sleeve via an upper connecting seat and a lower connecting seat. The upper connecting seat is fixedly connected to the top of the innermost sleeve. The lower connecting seat includes a transmission arm that traverses the interior through a long slot in the side wall of the innermost sleeve. The slot is connected to the top lug of the innermost piston via a pin. Each support arm assembly consists of multiple support arms connected by short shafts to form a scissor-like structure. The ends of the two short shafts forming the innermost scissor of the support arm assembly are rotatably connected to the upper connecting seat and the lower connecting seat, respectively.

[0016] Preferably, the sliding mechanism is a combination of a support plate and a universal ball bearing or a self-lubricating copper plate.

[0017] Preferably, the outer periphery of the support plate is provided with protrusions, which limit the horizontal movement range of the tire-connecting assembly.

[0018] Preferably, when all the corrective cylinders are extended to their maximum positions, the center of the tire receiving assembly and the center of the base assembly are aligned.

[0019] More preferably, the corrective cylinders are 3 or 4.

[0020] More preferably, the piston rod is fitted with a bearing at its top end.

[0021] Preferably, an orientation drive device is provided on the base assembly, and an arc-shaped rack is fixedly installed on the tire receiving assembly. The orientation device drives the tire receiving assembly to rotate within a certain range through a gear and rack mechanism to change the relative angle between the tire blank and the base. The arc-shaped rack is fixedly installed on the tire receiving seat, and the orientation drive device can slide in the vertical direction.

[0022] Preferably, an annular tire carcass inner wall support airbag is installed on the outer side of the pallet, and the airbag is supplied with air by its own air pump or an external air source.

[0023] The technical effects of this invention are as follows:

[0024] This invention discloses a giant engineering tire blank storage and transportation device. Through the cooperation of the centering component of the tire receiving assembly and the correction cylinder of the base assembly, a two-stage centering operation is achieved, thereby correcting the tire blank's alignment relative to the storage and transportation device's base. Before receiving the tire blank, the centering block of the centering component retracts into a ring shape to the inner position. The diameter of the arc plate formed by its arc plate is smaller than the tire blank's centering point, and its position is relatively high. Therefore, when the tire blank approaches the storage and transportation device, the centering block first enters the centering point. When it reaches an appropriate height, the lifting of the storage and transportation device stops. Simultaneously, the centering cylinder of the storage and transportation device is operated to cause the centering block to expand outward and press against the centering point. Through the interaction of forces between the tire receiving assembly and the centering point, the tire receiving assembly and the base assembly slide relative to each other via a sliding mechanism, thereby aligning the center of the tire receiving assembly with the center of the tire blank. Then, the centering cylinder is operated to retract the centering block appropriately, preventing the centering block from continuously squeezing the tire blank's centering point. The storage and transportation device is then lifted until the entire weight of the tire blank is completely placed on the storage and transportation device, at which point the operation stops. After the loading equipment has completely released the tire carcass and left the working area, the hydraulic cylinder of the storage and transportation device pushes the inner side of the outer wall of the tire receiving seat, causing the tire receiving assembly to return to the position aligning with the center of the base. Then, a locking device locks the tire receiving assembly to the base assembly to prevent rotation. The drive cylinder of the sidewall support mechanism is operated to extend the sidewall support arm assembly to the appropriate position to support the inner sidewall of the tire carcass.

[0025] The sliding mechanism can be a combination of a support plate and either a universal ball bearing or a self-lubricating copper plate, achieving the same purpose. Using a universal ball bearing makes the tire assembly easier to move, but incurs higher costs.

[0026] Further functionality – tire alignment adjustment;

[0027] In the actual production of new tires, during the transfer of the pre-carved tire blank to the vulcanizing machine, the pre-carved pattern on the tire blank may not match the pattern on the mold in the vulcanizing machine. Existing equipment can only align the pattern by rotating the transport vehicle and making multiple trial adjustments. To address this, the storage and transport device of this invention adds a tire orientation adjustment function. By rotating the tire receiving assembly, the relative orientation angle between the tire blank and the base of the storage and transport device can be adjusted. The deviation angle only needs to be calculated once for each combination of vulcanizing machine and vulcanizing mold.

[0028] A directional drive device is installed on the base assembly of the storage and transportation device, and an arc-shaped rack is installed on the tire receiving assembly. The arc-shaped rack is fixedly installed on the tire receiving seat, and the directional drive device can slide vertically. During tire receiving, the directional drive device slides downward to disengage from the arc-shaped rack to avoid hindering the horizontal movement of the tire receiving assembly. After tire receiving is completed, the directional drive device slides upward to mesh with the arc-shaped gear to drive the tire receiving assembly to rotate. Furthermore, the interaction between the gears in the reduction mechanism can replace the locking device between the tire receiving assembly and the base assembly.

[0029] Further features – a detachable disc tray:

[0030] In some production processes, it is necessary to lift the tire blank before performing certain operations, such as trimming the toe area of ​​the tire blank. This requires detaching the tire blank along with its pallet from the base and removing the base to clear space at the toe area for personnel to operate. To address this, the disc-shaped pallet on top of the tire receiving seat can be configured as an independent frame pallet, placed on the outer ring base plate of the tire receiving seat. When trimming the lower toe area of ​​the tire blank is required, lifting equipment can be used to lift the tire blank and pallet separately, and the remaining components of the storage and transport device can be removed. The frame pallet and the tire receiving seat are equipped with guide and positioning components to maintain their relative positions. When returning the frame pallet to the storage and transport device, the correction cylinder retracts, allowing the tire receiving assembly space to move horizontally. The guide and positioning components constrain the descent of the frame pallet, gradually aligning it with the tire receiving seat and returning it to its original position. Finally, the correction cylinder extends, returning the tire receiving assembly to its original position on the storage and transport device.

[0031] When using the storage and transportation device of the present invention, the tire blanks can be transported to workstations such as giant engineering tire blank carving machines and giant engineering tire blank repair robots without being lifted off the ground. The construction can be completed directly on the storage and transportation device, minimizing the deformation of the tire blanks.

[0032] This invention utilizes the stable circular structure at the toe opening of the tire blank as a positioning reference. Through the cooperation of the centering component at the toe opening of the tire receiving assembly and the correction cylinders of the base assembly, dual correction is achieved. This corrects the center position of the tire blank and the storage and transportation device during the tire blank unloading process, preventing the tire blank from falling into the storage and transportation device and causing eccentricity, tilting, or other states. At the same time, it provides internal support for the tire blank during the tire blank turnover process, allowing it to better maintain its shape, which can ensure the processing quality of subsequent processes and improve the quality of the final tire product.

[0049] To better understand the present invention, the following explanation is provided in conjunction with the accompanying drawings and specific embodiments.

[0050] Example 1

[0051] like Figure 1-4 As shown, a giant engineering tire blank storage and transportation device is characterized by including a tire receiving assembly 1, a tire sidewall support mechanism 2, and a base assembly 3.

[0052] The tire-attaching assembly 1 is a hollow annular structure, disposed on the base assembly 3, and includes a tire-attaching seat 11 and a toe-aligning assembly 12. Figure 5-7 As shown, the tire receiving seat 11 includes two hollow ring structures, an inner ring 111 and an outer ring 112, which are connected as one piece. The upper surface of the outer ring 112 is connected to the upper hollow disc-shaped tray 114 by a rib plate 113. The disc-shaped tray 114 is adapted to the lower tire side profile of the tire blank. A plurality of support plates 115 are evenly distributed around the circumference on the lower part of the outer ring 112.

[0053] The toe-mouth alignment component 12 is installed on the upper surface of the inner ring 111, such as Figure 8As shown, the toe-mouth alignment assembly 12 includes a toe-mouth block 121, a slide rail 122, a cam disk 123, and an alignment cylinder 124. The toe-mouth block 121 includes a bottom surface 125 and a vertical arc surface 126. Multiple toe-mouth blocks 121 are evenly distributed around the center of the tire seat 11 to form a ring. The bottom of the vertical arc surface 126 is located at the edge of the bottom surface 125 near the center and is adapted to the inner side of the toe-mouth of the tire blank. Each toe-mouth block 121 is connected to the upper surface of the bottom plate of the inner ring 111 through the slide rail 122. The alignment cylinder 124 can push the cam disk 123 to rotate, causing the toe-mouth block 121 to slide synchronously in the radial direction along the slide rail 122. Initially, the toe-mouth centering component 12 is in an inward-retracted state. After the vertical arc surface 126 enters the inner side of the toe mouth of the fetus, the toe-mouth block 121 moves synchronously from the center outward under the drive of the centering cylinder 124 and the cam disk 123, forming a ring tightly against the inner side of the toe mouth. At this time, the center of the ring structure of the toe-mouth block is the center of the toe mouth of the fetus.

[0054] like Figure 3 As shown, the base assembly 3 includes a base frame 31, a steering cylinder 32, a wheel seat, and a wheel 33. The base frame 31 includes an inner connecting groove 34 and an outer support ring 35. The inner connecting groove 34 is a hollow annular structure, including an annular bottom surface 341 and a vertical sidewall 342 located on the outer edge of the annular bottom surface 341. The inner side of the outer support ring 35 is connected to the outer periphery of the sidewall 342. A sliding mechanism is installed on the outer periphery of the upper surface of the outer support ring 35, corresponding to the support plate 115 of the tire receiving seat 11. In this embodiment, it is a universal ball bearing 36. The tire receiving assembly 1 is supported by the contact surface between the universal ball bearing 36 and the support plate 115, and the tire receiving assembly 1 can move horizontally above the base assembly 3. The steering cylinders 32 are evenly distributed around the center of the base frame 31 on the surface of the outer support ring 35, with 3 or 4 cylinders provided. The cylinder body is fixed radially to the outer sidewall of the inner connecting groove 34. The piston rod is equipped with a bearing at its top, allowing for relative displacement between the piston rod and the sidewall. The bearing reduces frictional resistance. When extended, the piston rod presses against the inner side 117 of the outer wall of the inner ring of the tire receiving seat 11. The alignment cylinder 32 pushes the outer side 117 of the inner ring, causing the tire receiving seat 11 to move horizontally above the base assembly 3, aligning the center of the tire receiving assembly 1 with the center of the base assembly 3. Preferably, the alignment cylinders 32 are fully extended to their maximum positions, ensuring that the center of the tire receiving assembly 1 aligns with the center of the base assembly 3. The outer periphery of the support plate 115 may further be provided with protrusions 116, which restrict the horizontal movement of the tire receiving assembly 1.

[0055] The tire sidewall support mechanism 2 includes a drive cylinder 21, a guide sleeve 22, and several support arm assemblies 25 evenly distributed along the circumference. The guide sleeve 22 has at least two stages and can be raised, lowered, and slid sequentially. In this embodiment, for example... Figure 3 The diagram shows a three-stage system. The bottom of the outermost sleeve is fixed to the center of the base frame 31 of the base assembly 3. The top of the innermost sleeve 221 is connected to the support arm assembly 25. The innermost flange 222 is fixed to the inner side of the middle of the innermost sleeve 221. The guide sleeve 22 has a multi-stage drive cylinder 21 inside. The top of the second innermost piston is connected to the flange 222 to drive the lifting and lowering of the innermost sleeve 221, thereby driving the lifting and lowering of the support arm assembly 25. The innermost piston 211 drives the extension or retraction of the support arm assembly 25. The outer end of the support arm assembly 25 is an arc-shaped support plate 26 adapted to the shape of the inner wall of the tire sidewall.

[0056] The support arm assembly 25 is connected to the innermost sleeve 221 via the upper connecting seat 23 and the lower connecting seat 24, such as Figure 10 and Figure 3 As shown, the upper connecting seat 23 is fixedly connected to the top end of the innermost sleeve 221. The lower connecting seat 24 includes an upper ring 245 and a lower ring 246. The upper ring and the lower ring are welded together with multiple vertical plates 247 and are fitted onto the outside of the innermost sleeve 221. The outer ring arm transmission arm 241 passes through the interior through the long slot hole 244 on the side wall of the innermost sleeve 221. The hole is connected to the top ear ring 242 of the innermost piston through a pin 243 (the middle hole coincides with the pin). Each support arm group 25 is formed by multiple support arms connected by short shafts 27 to form a scissor structure. The ends of the two short shafts 27 forming the innermost scissor are respectively rotatably connected to the vertical plates 247 of the upper connecting seat 23 and the lower connecting seat 24.

[0057] An orientation drive device can also be provided on the base assembly, and an arc-shaped rack can be fixedly installed on the tire receiving assembly. The arc-shaped rack is fixedly installed on the tire receiving seat, and the orientation drive device can slide in the vertical direction.

[0058] A ring-shaped tire carcass inner wall support airbag may preferably be installed on the outer side of the pallet, and the airbag is supplied with air by its own air pump or an external air source.

[0059] Example 2

[0060] like Figure 9 As shown, the tire sidewall support mechanism 2 in this embodiment does not require lifting. In this structure, the guide sleeve 22 has only one stage, the upper connecting seat 23 is fixedly connected to the top of the guide sleeve 22, and the position of the guide sleeve 22 remains unchanged. The corresponding drive cylinder 21 also has only one stage, with the upper end of its cylinder body fixed to the inner side of the guide sleeve 22. The piston top lug is connected to the transmission arm of the lower connecting seat 24 via a pin. When the hydraulic cylinder piston moves upward, it drives the support arm to extend radially, reaching the position of the upper tire sidewall inner wall to support the tire carcass. (The connection method between the sleeve and the cylinder is not specifically shown in the figure; the connection method between the piston and the lower connecting seat is the same as in Embodiment 1.)

[0061] This applies to a single-size tire blank that does not require adjustment of the height of its support arm or other auxiliary means to load the tire blank onto this storage and transport device.

[0062] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
