Description

Technical Field

[0001] This application relates to the field of transfer platform technology, and in particular to a safe transfer platform for the convenient collection of bagged polyacrylamide finished products. Background Technology

[0002] Polyacrylamide is a high-molecular polymer widely used in water treatment, oil extraction, papermaking, and other fields. The finished product is typically packaged in bags for easy storage and transportation. During the production of bagged polyacrylamide, the finished product needs to be transported from the end of the production line to the storage area; therefore, the efficiency and safety of this transfer process are particularly important. In related technologies, a common transfer method involves using conveyor belts in conjunction with iron frames. The iron frames, typically welded from structural steel, have a simple structure and are placed below the end of the conveyor belt to receive the falling bagged finished products. During operation, the bagged finished products delivered by the conveyor belt are stacked on the iron frames. Once a certain quantity has been stacked, forklifts or other equipment are used to remove the entire iron frame along with the stacked bagged finished products. The bagged finished products are then unloaded from the iron frames in the warehouse area.

[0003] In the process of developing this application, at least the following problems were found in the technology: First, the fixed height of the iron frame cannot be adapted to the conveyor belt outlets of different heights, which may result in excessive drop when the bagged finished products fall from the conveyor belt onto the platform, causing a violent impact and posing a risk of packaging damage; Second, since the platform height of the iron frame is fixed and cannot be expanded, the number of bagged finished products that can be collected and stacked at one time is limited, requiring workers to frequently operate forklifts to replace empty iron frames, which is time-consuming and labor-intensive. Utility Model Content

[0004] To facilitate adjustment of the receiving height of bagged finished products, increase the number of bagged finished products collected and stacked at one time, and reduce manpower consumption, this application provides a safe transfer platform for convenient collection of bagged polyacrylamide finished products.

[0005] The technical solution adopted in this application for a safe and convenient transfer platform for collecting and transporting bagged polyacrylamide finished products is as follows: A safe transfer platform for convenient collection of bagged polyacrylamide finished products includes a base, a support rod fixedly mounted on the base, a lifting platform slidably mounted on the support rod along the vertical direction, the lifting platform for carrying the bagged finished products, a mounting frame fixedly mounted on the support rod, a motor fixedly mounted on the mounting frame, and a lead screw rotatably mounted on the mounting frame. The lead screw is coaxially fixed with the drive shaft of the motor and threadedly engaged with the lifting platform.

[0006] By adopting the above technical solution, the motor drives the lead screw to rotate, and the lead screw drives the lifting platform to slide vertically along the support rod, thereby realizing the adjustment of the lifting platform height. This adapts to the different heights of the conveyor belt outlets, reduces the drop difference when bagged finished products fall, and lowers the risk of packaging damage. At the same time, during the palletizing process, the lifting platform can be gradually lowered as the palletizing height increases. The lifting platform can carry more bagged finished products, increasing the number of bagged finished products collected and stacked at one time, reducing the number of transfers, and reducing manpower consumption.

[0007] Preferably, a safety railing is provided around the lifting platform to prevent the bagged finished product from falling off the lifting platform.

[0008] By adopting the above technical solutions, the safety railing forms a protective structure that prevents bagged finished products from slipping off the edge of the lifting platform during palletizing and transfer. This ensures the safety of the bagged finished products, avoids the risk of injury to personnel, and improves the safety of the operation process.

[0009] Preferably, the safety railing consists of several layers, all of which are arranged vertically in sequence. Connectors are provided between adjacent layers to limit the maximum distance between adjacent layers. The uppermost layer is fixedly connected to a support rod, and the lowermost layer is fixedly connected to a lifting platform.

[0010] By adopting the above technical solution, when the lifting platform descends, each layer of railings unfolds sequentially under the constraint of the connectors, expanding the protection range of the safety railings. The connectors also limit the maximum distance between adjacent layers of railings, preventing the bagged finished products from falling out of the gaps due to excessive distance between adjacent layers of railings. When the lifting platform rises, each layer of railings can retract and fold, preventing the safety railings from obstructing the bagged finished products from entering the lifting platform from the conveyor belt.

[0011] Preferably, the connector includes a sliding shaft, a rotating shaft, and a connecting rod. A groove is formed on the shelf in the horizontal direction. The sliding shaft rotates and slides in the groove in the horizontal direction. A rotating shaft is rotatably provided on the shelf, and the axes of the rotating shaft and the sliding shaft are parallel to each other. The connecting rod is inclined between adjacent shelves. One end of the connecting rod is fixedly connected to the rotating shaft on one of the shelves, and the other end of the connecting rod is fixedly connected to the sliding shaft on the other shelf.

[0012] By adopting the above technical solution, when the distance between adjacent layers increases, one end of the connecting rod twists and slides in the groove through the sliding shaft, and the other end of the rotating shaft rotates. The connecting rod deflects around the rotating axis in a direction that tends to be vertical. When the connecting rod is vertical or abuts against the end wall of the groove, the distance between adjacent layers reaches its maximum and cannot continue to increase. This prevents the gap between adjacent layers from being too large, causing the bagged finished product to fall out of the gap.

[0013] Preferably, the sliding shaft abuts against the end wall of the sliding groove, and the sliding groove prevents the sliding shaft and the rotating shaft from being collinear in the vertical direction.

[0014] By adopting the above technical solution, when the sliding shaft abuts against the end wall of the chute, the rotation angle of the connecting rod can be limited, avoiding the sliding shaft and the rotating shaft from being collinear in the vertical direction, which would cause the connecting part to have a dead point perpendicular to the chute, ensuring that the railing can be flexibly extended and retracted, and ensuring the normal operation of the safety railing.

[0015] Preferably, the support rod is fitted with a sliding ring corresponding to the shelf, the sliding ring is slidably connected to the support rod, and the sliding ring is fixedly connected to the corresponding shelf.

[0016] By adopting the above technical solution, the slip ring slides synchronously along the support rod with the railing, which guides the movement of the railing, prevents the railing from shifting or swaying during the extension and retraction process, and enhances the structural stability of the safety railing.

[0017] Preferably, the support rod has several insertion holes, all of which are evenly and spaced apart in the vertical direction. The uppermost slip ring is threaded with a locking rod that passes through the inside and outside of the slip ring. One end of the locking rod is coaxially fixed with a knob, and the other end of the locking rod is inserted into any of the insertion holes and abuts against the insertion hole.

[0018] By adopting the above technical solution, rotating the knob allows the locking rod to be inserted into the corresponding hole, fixing the uppermost slip ring at different heights of the support rod, thereby fixing the uppermost layer rail at different heights, and thus fixing the highest position of the safety rail, preventing the safety rail from obstructing the bagged finished products from entering the lifting platform from the conveyor belt.

[0019] Preferably, the base has four casters at its bottom corners and a push handle fixedly installed on one side of the base.

[0020] By adopting the above technical solution, workers can use a push handle and rollers to move the platform as a whole, making it easy to transfer the platform to different conveyor belt ends or storage areas, thus enhancing the platform's flexibility.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a base, support rod, lifting platform, mounting frame, motor, and lead screw, the height of the lifting platform can be electrically adjusted, which can be adapted to the conveyor belt discharge port of different heights, reducing the risk of packaging damage. At the same time, the lifting platform can be gradually lowered during the palletizing process, increasing the number of bagged finished products that can be stacked at one time, reducing the frequency of changing empty platforms and the number of forklift operations, and reducing labor consumption. 2. By setting up safety railings, an effective protective structure can be formed, preventing the bagged finished products from sliding off the edge of the lifting platform during the stacking and transfer of bagged finished products. This not only ensures the integrity of the bagged finished products but also avoids the risk of bagged finished products falling and injuring workers, significantly improving operational safety. 3. By setting up layers, sliding shafts, rotating shafts, connecting rods, and sliding grooves, the safety guardrails can extend and retract as the lifting platform rises and falls. When the lifting platform descends, each layer unfolds to expand the protection range, and the connecting parts can limit the maximum distance between adjacent layers to prevent bagged finished products from falling out of the gaps. When the lifting platform rises, each layer retracts and folds to avoid obstructing the entry of bagged finished products into the lifting platform. Attached Figure Description

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses a safe transport platform for the convenient collection of bagged polyacrylamide products. (Refer to...) Figure 1 It includes a rectangular base 1, with braked rollers 15 installed at the four corners of the bottom of the base 1, and a push handle 16 fixedly welded to one side of the base 1 to facilitate manual movement or positioning of the entire transfer platform.

[0028] Reference Figure 1The base 1 has four vertically extending support rods 11 fixedly installed at its four corners. Mounting brackets 12 are fixedly installed on the support rods 11. In this embodiment, two mounting brackets 12 are provided, and the two mounting brackets 12 are symmetrical; each mounting bracket 12 is fixedly connected to the top of two adjacent support rods 11. A motor 13 is fixedly installed on the mounting bracket 12 by bolts. A downwardly extending lead screw 14 is rotatably installed on the mounting bracket 12 via bearings. The axis of the lead screw 14 is parallel to the support rods 11, the bottom of the lead screw 14 is rotatably connected to the base 1 via bearings, and the top of the lead screw 14 is coaxially fixed to the drive shaft of the motor 13.

[0029] Reference Figure 1 All support rods 11 slide vertically together to form a lifting platform 17, which is a rectangular platform used to support bagged finished products. The lifting platform 17 is threadedly engaged with the lead screw 14, meaning that a nut block that mates with the lead screw 14 is fixed on the lifting platform 17. When the motor 13 drives the lead screw 14 to rotate forward and backward, it causes the lifting platform 17 to rise and fall along the support rods 11, thereby adjusting the receiving height of the lifting platform 17. This adapts to the discharge of conveyor belts of different heights and minimizes the height difference between the conveyor belt and the lifting platform 17, avoiding the risk of packaging damage. At the same time, during the stacking process, the lead screw rotates and gradually lowers the lifting platform, increasing the number of bagged finished products collected at one time, reducing the frequency of platform replacement, and reducing labor costs.

[0030] To prevent bagged finished products from falling off the edge of the lifting platform 17 during palletizing and transfer, and to improve safety, refer to... Figure 1 A safety railing 2 is installed around the lifting platform 17. The safety railing 2 consists of several layers of railings 21, each layer of railings being a rectangular frame in the horizontal plane, and all layers of railings 21 are arranged sequentially in the vertical direction. A sliding ring 111 corresponding to the middle layer of railing 21 is also fitted on the support rod 11. The sliding ring 111 is slidably connected to the support rod 11 in the vertical direction and is fixedly connected to the corresponding layer of railing 21.

[0031] Reference Figure 1 and Figure 2 The topmost railing 21 is detachably fixed to the support rod 11, while the bottommost railing 21 is fixedly connected to the lifting platform 17. Several connectors 3 are provided between adjacent railings 21 to limit the maximum distance between them. When the lifting platform 17 descends, the railings 21 move away from each other under the constraint of the connectors 3, causing the safety railing 2 to extend vertically and expand its protective range.

[0032] Reference Figure 1 and Figure 2The connecting member 3 includes a sliding shaft 31, a rotating shaft 32, and a connecting rod 33. Several grooves 211, each corresponding to a connecting member 3, are formed on the shelf 21, with the grooves 211 oriented horizontally. The sliding shaft 31 is rotatably fitted into the groove 211 and can slide horizontally along the groove. The rotating shaft 32 is rotatably mounted on the shelf 21, with its axis parallel to the axis of the sliding shaft 31. The connecting rod 33 is inclined between adjacent shelves 21. The top end of the connecting rod 33 is fixedly connected to the rotating shaft 32 on the upper shelf 21; the bottom end of the connecting rod 33 is fixedly connected to the sliding shaft 31 on the lower shelf 21. The sliding shaft 31 abuts against the end wall of the sliding groove 211. When the sliding shaft 31 slides to the end of the sliding groove 211 near one end of the sliding shaft 31, the sliding shaft 31 and the rotating shaft 32 are vertically misaligned and cannot be collinear in the vertical direction. This avoids the sliding groove 211 and the connecting rod 33 being perpendicular to each other, thus preventing a dead point in force transmission and making it difficult for adjacent layers 21 to approach each other. Furthermore, when the sliding shaft 31 slides to the end of the sliding groove 211 near one end of the sliding shaft 31, the connecting rod 33 is in its most vertical state, and the distance between adjacent layers 21 reaches its maximum, preventing further expansion. This prevents the bagged finished product from falling out of the gap due to excessively large distances between adjacent layers 21.

[0033] To facilitate adjustment of the height of the top of safety barrier 2 and prevent it from interfering with the entry of bagged finished products into the lifting platform 17, refer to... Figure 1 and Figure 3 The support rod 11 is also provided with several evenly spaced insertion holes 112 along the vertical direction. A locking rod 113, threaded through the inner and outer parts of the uppermost slip ring 111, is threaded onto the uppermost slip ring 111. One end of the locking rod 113 is coaxially fixed with a knob 114, and the other end is inserted into any of the insertion holes 112, abutting against the hole. By rotating the knob 114, the other end of the locking rod 113 can be inserted into or removed from the insertion hole 112 on the support rod 11, thus allowing the locking rod 113 to be inserted into insertion holes 112 at different heights. By inserting the locking rod 113 into insertion holes 112 at different heights, the height of the uppermost shelf 21 can be adjusted, thereby adjusting the top height of the safety railing 2 to prevent the top of the safety railing 2 from being too high and interfering with the entry of bagged finished products into the lifting platform.

[0034] The implementation principle of a safe transfer platform for convenient collection of bagged polyacrylamide products according to an embodiment of this application is as follows: During use, workers move the platform to the end of the conveyor belt using a push handle 16 and rollers 15. Based on the height of the conveyor belt outlet, the uppermost layer 21 is first fixed at a suitable height using locking rods 113 to prevent the safety guardrails 2 from interfering with the falling material. Next, the motor 13 drives the lead screw 14 to rotate, adjusting the height of the lifting platform 17 so that the platform surface of the lifting platform 17 is as close as possible to the height of the outlet, reducing the impact when the bagged finished product falls. As the height of the bagged finished product on the lifting platform 17 increases, the motor 13 drives the lifting platform 17 to gradually descend. Simultaneously, each layer 21 of the safety guardrails 2 unfolds under the constraint of the connecting parts 3, always maintaining protection for the bagged finished product. This facilitates adjustment of the receiving height of the bagged finished product, increases the number of bagged finished products collected and stacked at one time, and reduces manpower consumption.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
