Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and more specifically, to a partial transfer device for cutting mud. Background Technology

[0002] In the industrial production process of ceramic clay, the clay preparation stage places extremely high demands on workshop space utilization and transfer efficiency. Currently, most ceramic clay preparation workshops adopt a layered design concept, staggering the filter press system with the clay refining and cutting machine, aiming to improve the land use efficiency of the factory through three-dimensional space planning. However, this layout model faces significant space waste and inconvenience in actual operation. Specifically, after the mud cutting machine completes the cutting of mud segments, the cut segments need to be temporarily placed on pallets for subsequent processing. Because large transfer equipment such as forklifts requires sufficient operating space, the current process can only place the pallets carrying the mud segments in an open area outside the equipment area. This practice not only directly occupies a large amount of open space that can be used for other production activities, but also forces a lengthening of the logistics path within the workshop, indirectly reducing production turnover efficiency. Meanwhile, the area below the filter press system on the inside of the sludge cutter has a large amount of unused space due to the limited installation height of the filter press equipment. Because of insufficient vertical space, these areas cannot meet the requirements for forklift access and operation, resulting in them remaining vacant for extended periods. This further exacerbates the double waste of factory space – the low-height areas are not effectively utilized, and the placement of external pallets further restricts available space in other production processes. Furthermore, traditional pallet handling methods suffer from low equipment compatibility when dealing with such complex spatial layouts. Existing moving mechanisms are mostly general-purpose designs, not optimized for the specific environment of ceramic clay workshops. Their height, load-bearing structure, and compatibility with forklifts are poor, making it difficult to achieve efficient pallet handling and handover within confined spaces. At the junction of height-restricted areas and open areas, problems such as excessive mechanism thickness and insufficient turning flexibility often lead to logistics interruptions or cumbersome operations, severely impacting production continuity. Utility Model Content

[0003] The purpose of this invention is to provide a partial transfer device for mud cutting, in order to solve the problem mentioned in the background art that after the mud cutting machine completes the mud segment cutting, the cut mud segments need to be temporarily placed on a pallet for subsequent processing. Because large transfer equipment such as forklifts requires sufficient operating space, existing processes can only place the pallet carrying the mud segments in an open area outside the equipment area.

[0004] To achieve the above objectives, this utility model provides a mud-cutting local transfer device, including a trolley, a drive mechanism installed at the rear end of the trolley, and tracks provided on both sides of the trolley. The trolley moves in a straight line along the tracks driven by the drive mechanism. A tray is detachably installed on the trolley. The trolley includes an outer frame, and a lifting base plate is provided on the inner side of the lifting outer frame. The lifting base plate is adjusted in height by a height adjustment mechanism.

[0005] This setup uses a trolley as the core load-bearing structure, powered by a drive mechanism, enabling the trolley to move in a straight line along the tracks on both sides, thus achieving horizontal transfer of the pallet. The detachable pallet on the trolley is used to place the cut mud segments, while the inner side of the trolley's outer frame is equipped with a lifting base plate. The height of the lifting base plate can be adjusted using a height adjustment mechanism, thereby changing the height position of the pallet.

[0006] Preferably, the top surface of the lifting platform has two notches. When the lifting platform is raised, the forks of the forklift can be inserted under the lifting platform and pass through the notches to lift the pallet for transfer.

[0007] This feature provides a channel for the forklift's forks through the notch in the lifting platform. When the lifting platform is raised, the forklift's forks can extend from below the platform and pass through the notch to lift the pallet for transport.

[0008] Preferably, the bottom of the lifting base plate is equipped with two auxiliary pulleys, and the front ends of both sides of the outer frame are equipped with side pulleys.

[0009] The two auxiliary pulleys at the bottom of the lifting platform reduce friction between the platform and the ground when the platform slides; the side pulleys on both sides of the outer frame help the trolley stay stable and reduce swaying when it moves along the track.

[0010] Preferably, there are two height adjustment mechanisms, which are symmetrically arranged on both sides of the outer frame. Each height adjustment mechanism includes a lead screw, which is rotatably installed inside the side of the outer frame. A lead screw slider is threaded onto the lead screw. The top of the lead screw is driven to rotate by a lead screw motor. The inner sides of the two lead screw sliders are respectively connected and fixed to both ends of the lifting base plate.

[0011] In this height adjustment mechanism, the lead screw rotates under the drive of the lead screw motor. The lead screw slider on the lead screw moves along the lead screw axis as the lead screw rotates. Since the lead screw slider is connected and fixed to the lifting base plate, it drives the lifting base plate to achieve height adjustment.

[0012] Preferably, the drive mechanism includes a drive motor and a drive shaft. The drive motor is connected to the rear end face of the trolley via a mounting plate. A drive gear is mounted on the output shaft of the drive motor, and a driven gear is mounted on the drive shaft. The drive gear and the driven gear mesh. Both ends of the drive shaft are fixedly mounted with wheels, which roll along the track to move.

[0013] In this drive mechanism, the output shaft of the drive motor drives the drive gear to rotate. The drive gear meshes with the driven gear on the drive shaft, thereby driving the drive shaft to rotate. The wheels at both ends of the drive shaft rotate accordingly, causing the trolley to roll along the track.

[0014] Preferably, a guide bar is installed on the track, and an annular groove is provided on the outer circumference of the traveling wheel, the annular groove cooperating with the guide bar in a rolling motion.

[0015] This feature involves the guide strips on the track engaging with the annular grooves on the outer wall of the wheels. As the trolley moves, the guide strips embed themselves in the annular grooves, guiding and restricting the movement of the wheels.

[0016] Preferably, the drive shaft is connected and fixed to the rear end face of the trolley via two bearing seats.

[0017] This bearing housing provides stable support for the drive shaft while reducing frictional resistance during drive shaft rotation.

[0018] Preferably, a limit block is installed at the front end of the track. The limit block slides with the track to adjust its position and is fixed and locked by bolts to limit the travel range of the trolley.

[0019] This setting ensures that when the trolley travels to the limit block, it will be blocked by the limit block, thus limiting the trolley's travel range.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: In this sludge transfer device, regarding space utilization, the device achieves efficient use of height-restricted areas through the cooperation of the trolley and the track. The trolley's compact structure, combined with the lateral installation design of the side pulleys and traveling wheels, significantly reduces the overall thickness of the device, allowing it to flexibly move through low-height spaces such as below the filter press system. This transforms previously unused areas into temporary sludge storage points, avoiding double waste of plant space. Simultaneously, the limiting blocks at the end of the track allow for adjustment of the trolley's travel according to actual needs, further enhancing the flexibility of space planning and making the equipment layout more aligned with the layered design of the workshop. In terms of transfer efficiency, the coordinated operation of the drive mechanism and the height adjustment mechanism significantly shortens the logistics path. The drive motor drives the traveling wheels to move precisely along the track via gear transmission. Combined with the positioning effect of the guide strip and the annular groove of the traveling wheels, this ensures the trolley moves stably without deviation in a straight line, quickly transferring pallets carrying mud sections from the confined area inside the mud cutter to the open area outside. The screw-driven lifting base plate can flexibly adjust its height. When raised, it provides a precise docking channel for the forklift's forks through a notch, completing the transfer without manual adjustment of the pallet position. This significantly reduces the operation time in intermediate steps and improves production turnover efficiency. In terms of operational adaptability, the device has undergone multiple optimizations for the ceramic workshop environment. The auxiliary pulleys at the bottom of the lifting platform reduce friction with the ground, making height adjustment smoother; the side pulleys on the outer frame enhance the stability of the trolley on the track, preventing swaying caused by uneven clay weight. The detachable tray design facilitates individual cleaning and maintenance, while the robust support of the drive shaft by the bearing housing and the adjustable fixing method of the limit blocks improve the reliability of the device under long-term high-intensity operation and reduce the equipment failure rate. In addition, the device perfectly connects the logistics chain between confined spaces and open areas through the "short-distance transfer of small vehicles + forklift docking" mode. Compared with traditional general-purpose mobile mechanisms, its highly adaptable structural design completely solves the pain point of not being able to use forklifts in areas with limited height, and realizes a seamless connection from clay cutting to transfer, effectively ensuring the continuity of production and providing a practical technical solution for space optimization and efficiency improvement in ceramic clay preparation workshops.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0023] This utility model provides a device for local transfer of sludge, such as... Figure 1 , Figure 2 As shown, the device includes a trolley 1, a drive mechanism 4 is installed at the rear of the trolley 1, and rails 2 are provided on both sides of the trolley 1. The trolley 1 moves in a straight line along the rails 2 driven by the drive mechanism 4. A tray 3 is detachably installed on the trolley 1. The trolley 1 includes an outer frame 11, and a lifting base plate 12 is provided on the inner side of the lifting outer frame 11. The lifting base plate 12 is lifted and adjusted by a height adjustment mechanism 14.

[0024] In use, the device uses a trolley 1 as its core supporting structure. Power is provided by a drive mechanism 4, enabling the trolley 1 to move linearly along the tracks 2 on both sides, thus achieving horizontal transfer of the pallet 3. The detachable pallet 3 on the trolley 1 is used to place the cut mud segments. A lifting base plate 12 is installed inside the outer frame 11 of the trolley 1. The height of the lifting base plate 12 can be adjusted using a height adjustment mechanism 14, thereby changing the height position of the pallet 3. The cooperation between the drive mechanism 4 and the tracks 2 allows the trolley 1 to move stably along a specific path, solving the problem of transferring mud segments between different areas. The detachable pallet 3 facilitates the loading and unloading of mud segments and the maintenance and replacement of the pallet 3. The height adjustment of the lifting base plate 12 creates conditions for subsequent docking with forklifts and other equipment, improving the versatility and flexibility of the device.

[0025] In this embodiment, as Figure 3 As shown, the top surface of the lifting base plate 12 has two notches 121. When the lifting base plate 12 is raised, the forks of the forklift are inserted under the lifting base plate 12 and pass upward through the notches 121 to lift the pallet 3 for transfer.

[0026] In use, the notch 121 on the lifting base plate 12 provides a channel for the forklift's forks. When the lifting base plate 12 is raised, the forklift's forks can extend from below the lifting base plate 12, and after passing through the notch 121, they can directly lift the pallet 3 for transport. This structural design eliminates the need for additional adjustments to the position of the pallet 3, simplifies the docking process between the forklift and the device, reduces operational steps during transport, improves transport efficiency, and ensures the stability of the pallet 3 during the lifting process.

[0027] Specifically, such as Figure 3As shown, two auxiliary pulleys 122 are installed at the bottom of the lifting base plate 12, and side pulleys 13 are installed on the front ends of the outer walls on both sides of the outer frame 11.

[0028] In use, the two auxiliary pulleys 122 at the bottom of the lifting base plate 12 reduce the frictional resistance between the lifting base plate 12 and the ground as it slides. Simultaneously, the auxiliary pulleys 122 provide support for the lifting base plate 12 as it slides. The side pulleys 13 on the outer walls of the outer frame 11 help stabilize the trolley 1 and reduce swaying as it moves along the track 2. The cooperation of the auxiliary pulleys 122 and the side pulleys 13 enhances the stability of the trolley 1 during movement, preventing it from tilting or deviating from the track 2 due to uneven mud placement, thus improving the safety of the device's operation.

[0029] Furthermore, such as Figure 3 As shown, there are two height adjustment mechanisms 14, which are symmetrically arranged on both sides of the outer frame 11. Each height adjustment mechanism 14 includes a lead screw 141, which is rotatably installed inside the side of the outer frame 11. A lead screw slider 143 is threaded onto the lead screw 141. The top of the lead screw 141 is driven to rotate by a lead screw motor 142, which is fixedly installed on the top side of the outer frame 11. The inner sides of the two lead screw sliders 143 are respectively connected and fixed to both ends of the lifting base plate 12.

[0030] In use, the lead screw 141 in the height adjustment mechanism 14 rotates under the drive of the lead screw motor 142. The lead screw slider 143 on the lead screw 141 moves axially along the lead screw 141 as the lead screw 141 rotates. Since the lead screw slider 143 is fixedly connected to the lifting base plate 12, it drives the lifting base plate 12 to achieve height adjustment. The lead screw 141 transmission has the characteristics of high precision and smooth operation, which can accurately control the lifting height of the lifting base plate 12 to meet the height requirements in different scenarios. The stable power provided by the lead screw motor 142 ensures the reliability of the lifting process, making the adjustment operation of the lifting base plate 12 convenient and efficient.

[0031] Furthermore, such as Figure 4 As shown, the drive mechanism 4 includes a drive motor 41 and a drive shaft 42. The drive motor 41 is connected to the rear end face of the trolley 1 through a mounting plate. A drive gear 411 is mounted on the output shaft of the drive motor 41, and a driven gear 421 is mounted on the drive shaft 42. The drive gear 411 and the driven gear 421 mesh. Both ends of the drive shaft 42 are fixedly mounted with traveling wheels 422, which roll along the track 2 to move.

[0032] In operation, the output shaft of the drive motor 41 in the drive mechanism 4 drives the drive gear 411 to rotate. The drive gear 411 meshes with the driven gear 421 on the drive shaft 42, thereby driving the drive shaft 42 to rotate. The traveling wheels 422 at both ends of the drive shaft 42 rotate accordingly, causing the trolley 1 to roll along the track 2. The gear transmission method has high power transmission efficiency and rapid response, allowing the trolley 1 to start and stop quickly, improving the moving efficiency of the trolley 1. The rolling of the traveling wheels 422 along the track 2 reduces the resistance during movement, allowing the trolley 1 to move flexibly even when carrying mud sections, ensuring the timely transfer of mud sections.

[0033] Furthermore, such as Figure 1 , Figure 4 As shown, a guide bar 21 is installed on the track 2, and an annular groove is provided on the outer circumference of the traveling wheel 422. The annular groove and the guide bar 21 roll together.

[0034] In use, the guide bar 21 on track 2 cooperates with the annular groove on the outer wall of the traveling wheel 422. During the movement of the trolley 1, the guide bar 21 is embedded in the annular groove, which guides and restricts the movement direction of the traveling wheel 422. This cooperation method can effectively prevent the trolley 1 from deviating laterally during movement, ensuring that the trolley 1 always moves in a straight line along track 2, improving the accuracy of the trolley 1's movement, and avoiding problems such as equipment collisions or mud falling due to deviation.

[0035] Furthermore, such as Figure 4 As shown, the drive shaft 42 is connected and fixed to the rear end face of the trolley 1 through two bearing seats 423, and the drive shaft 42 is rotatably connected to the bearing seats 423.

[0036] In use, the bearing housing 423 provides a stable support for the drive shaft 42, while reducing the frictional resistance when the drive shaft 42 rotates. The fixing method of the bearing housing 423 ensures the stability of the drive shaft 42 during rotation, avoids the drive shaft 42 from shaking or deviating due to uneven force, extends the service life of the drive shaft 42 and related components, and ensures the normal operation of the drive mechanism 4.

[0037] Furthermore, such as Figure 1 As shown, a limit block 22 is installed at the front end of the track 2. The limit block 22 slides with the track 2 to adjust its position and is fixed and locked by bolts to limit the travel range of the trolley 1.

[0038] When in use, when the trolley 1 travels to the limit block 22, it will be blocked by the limit block 22, thus limiting the travel range of the trolley 1. This structural design allows for flexible adjustment of the travel range of the trolley 1 according to actual production needs, preventing the trolley 1 from exceeding the range of the track 2 or colliding with other equipment due to excessive travel, thereby improving the safety of the device operation and adapting to the needs of different workshop layouts and production processes.

[0039] When using the mud-cutting partial transfer device of this utility model, firstly, the pallet 3 carrying the cut mud segments is placed on the lifting base plate 12 of the trolley 1, ensuring that the pallet 3 is placed stably. According to the workshop layout and transfer requirements, the limiting block 22 at the front end of the sliding track 2 is moved to a suitable position and fixed with bolts. The maximum travel range of the trolley 1 is set to avoid exceeding the safe area. Mud segment transfer stage: The drive motor 41 of the drive mechanism 4 is started. The output shaft of the drive motor 41 drives the drive gear 411 to rotate. The drive gear 411 meshes with the driven gear 421 on the drive shaft 42, thereby driving the drive shaft 42 to rotate. The traveling wheels 422 at both ends of the drive shaft 42 roll along the track 2. At the same time, the guide strip 21 on the track 2 is embedded in the annular groove of the traveling wheel 422 to ensure that the trolley 1 travels stably in a straight line. During this process, the side pulleys 13 on both sides of the outer frame 11 help the trolley 1 maintain balance and reduce shaking. Docking preparation stage: When the trolley 1 travels to the designated position for docking with the forklift (such as an open area outside the equipment area), the drive motor 41 is stopped. The lead screw motor 142 of the height adjustment mechanism 14 is started. The lead screw motor 142 drives the lead screw 141 to rotate, and the lead screw slider 143 on the lead screw 141 moves along the axis of the lead screw 141, causing the lifting base plate 12 to rise. The auxiliary pulley 122 at the bottom of the lifting base plate 12 reduces the frictional resistance with the ground, making the lifting base plate 12 move more smoothly.

[0040] Forklift transfer phase: Once the lifting platform 12 is raised to the appropriate height, the lead screw motor 142 is stopped. The forklift's forks extend from below the lifting platform 12, pass through the notch 121 on the lifting platform 12, directly contact the pallet 3 and lift it up. Then, the forklift carries the pallet 3 away to complete the transfer. Reset Phase: After tray 3 is removed, the lead screw motor 142 is started to rotate in the reverse direction, causing the lifting base plate 12 to descend to the initial position. The drive motor 41 is started again to rotate in the reverse direction, driving the trolley 1 back to the initial position along the track 2, waiting for the next transfer task.

[0041] Finally, it should be noted that the electronic components in the lead screw motor 142 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between the electrical components in the above working principle to complete the electrical connection. All of these are technologies known in the art.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
