Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of transfer devices, and in particular relates to a granite processing and transfer device. Background Technology
[0002] In the granite processing industry, moving devices play an indispensable role in everything from handling raw material slabs and transferring them between processing steps to loading and unloading finished products. Granite slabs are characterized by their large weight, high hardness, and smooth surface, which places stringent requirements on the stability, safety, and ease of operation during the moving process.
[0003] Currently, most granite processing and transport devices on the market are fixed-height structures, making it difficult to flexibly adjust the height of the bearing surface according to actual processing needs. In actual production scenarios, the inlet heights of different processing equipment vary significantly, and the operating height of workers and the stacking height of materials also differ during loading and unloading. Fixed-height transport devices often have obvious limitations when facing these diverse needs: when loading to higher processing equipment, workers need to use shims or manually lift the slabs, which not only increases labor intensity but also easily leads to slippage of slabs due to improper operation, causing safety accidents; while when feeding or unloading to lower equipment, the bearing surface may be too high, causing the slabs to be unstable, which also poses a safety hazard. In addition, the fixed-height design makes it difficult for the transport device to adapt to the connection needs between various processing steps. Different steps often require dedicated transport equipment, which not only increases equipment procurement costs but also occupies a lot of production space and reduces the continuity of the processing flow and production efficiency. Therefore, a granite processing and transport device is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a granite processing and transport device. By setting up a drive assembly and a lifting assembly, specifically, rotating the handle clockwise drives the bidirectional threaded rod to rotate, causing two moving blocks inside the crossbar to slide closer together. A limiting bracket then brings the bottom ends of the two sets of support rods together, thereby raising the height of the hinged bracket and the bearing plate. Counterclockwise rotation achieves the lowering function. This solves the problem that when loading materials onto higher processing equipment, workers must use shims or manually lift the slabs, which not only increases labor intensity but also easily leads to slippage and safety accidents due to improper operation. Conversely, when feeding or unloading materials onto lower equipment, the bearing surface may be too high, causing instability and posing a safety hazard. Furthermore, the fixed height design makes it difficult for the transport device to adapt to the connection needs between different processing steps. Different steps often require dedicated transport equipment, which not only increases equipment procurement costs but also occupies a large amount of production space, reducing the continuity of the processing flow and production efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a granite processing and transportation device, comprising a core load-bearing frame chassis, a load-bearing plate mounted on top of the chassis, an anti-slip silicone pad mounted on the top of the load-bearing plate, a push handle welded to the right side of the chassis, and a transportation mechanism that abuts against the chassis and the load-bearing plate. The transportation mechanism achieves stable load-bearing, flexible height adjustment, and smooth transportation of granite through lifting adjustment and shock absorption. The transportation mechanism includes a drive assembly, which includes a crossbar. The end of the crossbar is welded to the inner wall of the chassis. A bidirectional threaded rod is rotatably connected inside the crossbar. Moving blocks are threaded to the left and right sides of the outer surface of the bidirectional threaded rod. A lifting assembly is connected to the drive assembly. The lifting assembly includes two sets of support rods, the top ends of which are connected to hinged brackets via pins. The sides of the two hinged brackets furthest from the support rods are welded to the bottom of the load-bearing plate.
[0007] Furthermore, the transfer mechanism also includes vibration damping components, and there are four sets of vibration damping components. The four sets of vibration damping components contain the same parts, and the four sets of vibration damping components respectively abut against the four inner corners of the frame edge.
[0008] Furthermore, a crank handle is installed on the right side of the bidirectional threaded rod. The crank handle is located on the right side of the frame. Slide rails are provided on both the front and back sides of the inner edge of the frame. Two rollers are in contact with each of the two slide rails. Connecting rods are rotatably connected to each of the four rollers. The side of the four connecting rods away from the rollers is welded to the front and back sides of two moving blocks, respectively. The outer surfaces of the two moving blocks are slidably connected to the inside of the crossbar cavity. Openings are provided on both the front and back sides of the crossbar. The four connecting rods pass through the openings.
[0009] Furthermore, each of the four corners of the bottom of the bearing plate is welded with a sleeve, and each of the four sleeve cavities is slidably connected with a support leg. The bottom of each of the four support legs is welded to the four corners of the top of the frame. The side of each of the two sets of support rods away from the hinge bracket is connected to a limit bracket by a pin. The inside of each of the two sets of limit brackets is welded to the outer surface of the connecting rod. The inside of each of the two sets of support rods is connected by a reinforcing rod.
[0010] Furthermore, the vibration damping component located on the left side of the front includes a cavity, which is opened inside the outrigger cavity. A damping rod is welded to the top of the inner wall of the cavity, and a buffer spring is sleeved on the outer surface of the damping rod. A self-locking caster is welded to the bottom of the damping rod through a shaft. The top shaft of the self-locking caster passes through the cavity and extends to the bottom of the frame. The self-locking caster is located at the corner below the frame.
[0011] This utility model has the following beneficial effects:
[0012] 1. This utility model, through the setting of a drive component and a lifting component, specifically, rotates the crank clockwise to drive the bidirectional threaded rod to rotate, causing the two moving blocks inside the crossbar to slide closer to each other. Through the limiting bracket, the bottom ends of the two sets of support rods are brought together, thereby raising the height of the hinged bracket and the bearing plate. Rotating counterclockwise achieves the lowering function. During the adjustment process, the sleeve slides along the support leg and provides limiting support to ensure the stable lifting and lowering of the bearing plate. This structure can flexibly adjust the height according to the needs of the processing equipment, optimize the loading and unloading efficiency and operating posture, and, together with the anti-slip silicone pad, prevent material deviation, reduce labor intensity and safety risks.
[0013] 2. This utility model, by setting up a vibration damping component, specifically a self-locking omnidirectional wheel, gives the device omnidirectional movement capability, supports 360° turning to adapt to complex paths. Its self-locking function can fix the device to prevent slippage when positioning. When encountering uneven road surfaces, the vertical impact force is compressed and deformed by the buffer spring to achieve primary vibration damping. Combined with the damping force generated by the flow of medium in the damping rod, it effectively dissipates kinetic energy and suppresses secondary vibration, avoiding resonance damage to goods and equipment. This design not only extends the wheel life but also improves transportation safety and quietness, and reduces environmental noise pollution.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Please see Figures 1-5As shown, this utility model is a granite processing and transportation device, including a core support frame 111, a support plate 113 above the frame 111, an anti-slip silicone pad 114 installed on the top of the support plate 113, a push handle 112 welded to the right side of the frame 111, and a transportation mechanism 2. The transportation mechanism 2 abuts against the frame 111 and the support plate 113. The transportation mechanism 2 achieves stable support, flexible height adjustment, and smooth transportation of granite through lifting adjustment and shock absorption. The transportation mechanism 2 includes a drive assembly 21, which includes a crossbar 213. The end of the crossbar 213 is welded to the inner wall of the frame 111. A bidirectional threaded rod 212 is rotatably connected inside the crossbar 213. The left side of the outer surface of the bidirectional threaded rod 212 and the crossbar 213 are connected to the crossbar 213. The right side is threadedly connected to a moving block 215 and a lifting assembly 22. The lifting assembly 22 is connected to the drive assembly 21. The lifting assembly 22 includes two sets of support rods 223. The top of each set of support rods 223 is connected to a hinge bracket 225 via a pin. The side of each hinge bracket 225 away from the support rod 223 is welded to the bottom of the bearing plate 113. The transfer mechanism 2 also includes a vibration damping assembly 23. There are four sets of vibration damping assemblies 23. The four sets of vibration damping assemblies 23 contain the same components. The four sets of vibration damping assemblies 23 abut against the four corners of the inner edge of the frame 111. A crank handle 211 is installed on the right side of the bidirectional threaded rod 212. The crank handle 211 is located on the right side of the frame 111. Slide rails 214 are provided on the front and back sides of the inner edge of the frame 111. Each slide rail 214 has two rollers 216 inside. Each of the four rollers 216 is rotatably connected to a connecting rod 217. The side of each connecting rod 217 away from the rollers 216 is welded to the front and back of two moving blocks 215, respectively. The outer surface of each moving block 215 is slidably connected to the cavity of the crossbar 213. Openings are provided on both the front and back of the crossbar 213, through which the four connecting rods 217 pass. Sleeves 221 are welded to the four corners of the bottom of the bearing plate 113. Support legs 222 are slidably connected inside the cavities of each of the four sleeves 221. The bottom of each support leg 222 is welded to the four corners of the top of the frame 111. The side of each of the two sets of support rods 223 away from the hinged bracket 225 is connected to a limit bracket 226 via a pin. The frame 226 is welded to the outer surface of the connecting rod 217. The two sets of support rods 223 are connected by reinforcing rods 224. Turning the crank handle 211 clockwise drives the bidirectional threaded rod 212 to rotate, causing the two moving blocks 215 inside the crossbar 213 to slide closer to each other. The limiting bracket 226 brings the bottom ends of the two sets of support rods 223 together, thereby raising the height of the hinged bracket 225 and the bearing plate 113. Turning counterclockwise achieves the lowering function. During the adjustment, the sleeve 221 slides along the support leg 222 and provides limiting support to ensure the stable lifting and lowering of the bearing plate 113. This structure can flexibly adjust the height according to the needs of the processing equipment, optimize the loading and unloading efficiency and operating posture, and prevent material deviation with the anti-slip silicone pad 114, reducing labor intensity and safety risks.
[0025] The damping assembly 23, located on the left side of the front, includes a cavity 232 inside the support leg 222. A damping rod 233 is welded to the top of the inner wall of the cavity 232. A buffer spring 234 is fitted on the outer surface of the damping rod 233. A self-locking caster 231 is welded to the bottom of the damping rod 233 via a shaft. The top shaft of the self-locking caster 231 passes through the cavity 232 and extends to the bottom of the frame 111. The self-locking caster 231 is located at the lower corner of the frame 111. The device is given omnidirectional mobility and supports 360° turning to adapt to complex paths. Its self-locking function can fix the device to prevent slippage when positioning. When encountering uneven road surfaces, the vertical impact force is compressed and deformed by the buffer spring 234 to achieve primary shock absorption. Combined with the damping force generated by the flow of medium in the damping rod 233, it effectively dissipates kinetic energy and suppresses secondary vibration, avoiding resonance damage to goods and equipment. This design not only extends the wheel life but also improves transportation safety and quietness, and reduces environmental noise pollution.
[0026] A specific application of this embodiment is as follows: In use, the operator first turns the crank handle 211 clockwise as needed to drive the bidirectional threaded rod 212 to rotate. During the rotation of the bidirectional threaded rod 212, it will rotate inside the crossbar 213. At the same time, during the rotation of the bidirectional threaded rod 212, it will synchronously drive the two moving blocks 215 to move closer to each other. During the movement of the two moving blocks 215, they will slide inside the cavity of the crossbar 213. Thus, the crossbar 213 provides a certain degree of limitation for the movement trajectory of the moving blocks 215. At the same time, during the process of the two moving blocks 215 moving closer to each other, they will synchronously... The connecting rod 217 drives the roller 216 to move inside the slide rail 214. As the connecting rods 217 approach each other, the limiting bracket 226 drives the bottom ends of the two sets of support rods 223 to converge. During this convergence, the hinge bracket 225 moves upward. The rise of the hinge bracket 225 causes the bearing plate 113 to move synchronously, thereby adjusting the position and height of the bearing plate 113. Conversely, turning the crank 211 counterclockwise lowers the bearing plate 113. During the up-and-down movement of the bearing plate 113, the four sleeves 221 are also moved. Sliding on the outer surface of the support leg 222, the sleeve 221 and the support leg 222 provide limiting support, reducing the possibility of the bearing plate 113 shifting during lifting and lowering. Simultaneously, the sleeve 221 and the support leg 222 also provide a certain supporting force for the bearing plate 113. By adjusting the position and height of the bearing plate 113, it can be flexibly adjusted according to the height of different processing equipment and loading / unloading requirements, reducing height differences during worker handling, lowering labor intensity, and improving loading / unloading efficiency. For example, when loading materials onto engraving machines of different heights, the bearing plate 113 can be easily adjusted. The height of the support plate 113 is adjustable, eliminating the need for additional padding or lowering of equipment. Furthermore, the adjustable height of the support plate 113 allows the transport device to better adapt to various processes, increasing the continuity of the processing flow and reducing the need for dedicated handling equipment for different processes. A suitable support plate 113 height also allows workers to maintain a good operating posture, reducing fatigue and the risk of injury. Additionally, a lower support plate 113 height reduces the height from which the plate falls, minimizing injury to personnel and equipment. The anti-slip silicone pad 114 on the surface of the support plate 113 increases the friction between the plate and the support plate 113, preventing the granite from sliding or shifting during transport.
[0027] The self-locking caster wheel 231 provides the device with mobility, allowing 360° rotation to adapt to different transport paths. Simultaneously, the self-locking caster wheel 231 has a self-locking function; when the device is stationary at a designated position, locking the caster wheel 231 prevents accidental slippage. When the device is transported on uneven surfaces, bumps will cause the self-locking caster wheel 231 to generate a vertical impact force. This impact force is first transmitted to the buffer spring 234, which absorbs some of the vibration energy through its own compression deformation, achieving initial cushioning. Meanwhile, the damping rod 2... 33 moves synchronously with the compression or extension of the spring. Its internal damping medium flows through the gap to generate damping force, which consumes the kinetic energy generated by vibration, suppresses the secondary vibration when the buffer spring 234 rebounds, avoids the device from bumping and resonating, and reduces the damage to the granite caused by bumps. At the same time, the impact force on the self-locking caster 231 can be reduced by vibration reduction, thereby extending the service life of the self-locking caster 231. Moreover, vibration reduction can not only effectively improve the safety of transportation, but also reduce the generation of noise and reduce noise pollution to the surrounding environment.
