Description

Technical Field

[0001] This utility model relates to the field of logistics trolley technology, specifically to a stable logistics trolley. Background Technology

[0002] Logistics, centered on warehousing, promotes the synchronization of production and the market. Logistics refers to the entire process of planning, implementing, and managing raw materials, semi-finished products, finished products, and related information from the place of origin to the place of consumption, using transportation, storage, and distribution methods at the lowest cost, in order to meet customer needs. When carrying out short-distance logistics transportation within the factory area, logistics trolleys are often used.

[0003] Existing logistics trolleys are steered by push handles. When a fully loaded trolley is manually turned, its weight makes it difficult to maintain stable control during the turn. Sometimes the trolley drifts and collides with surrounding objects, causing damage to the goods. Furthermore, existing tiered shelves are generally fixed to the logistics trolley and their height cannot be adjusted according to the size of the goods. They can only store goods of a certain size, resulting in a narrow range of applications and insufficient flexibility in use. Utility Model Content

[0004] The purpose of this utility model is to provide a stable logistics trolley to solve the problem that existing logistics trolleys, which are turned by pushing handles, are difficult to control stably when manually turning a fully loaded logistics trolley due to their heavy weight. Sometimes the trolley drifts and collides with surrounding objects, causing damage to the goods.

[0005] To achieve the above objectives, a stable logistics trolley is provided, which includes a base plate, a C-shaped guardrail fixedly connected to the top of the base plate to form a unloading port, a receiving platform, a roller fixedly connected to the bottom of the receiving platform, a rotating shaft rotatably connected to the middle of the top of the receiving platform, and a first servo motor coaxially connected to the rotating shaft fixedly connected to the bottom of the receiving platform.

[0006] The base plate is set above the receiving platform under the connection of the rotating shaft. The base plate rotates synchronously with the rotating shaft under the drive of the first servo motor to adjust the orientation of the unloading port.

[0007] Both the bottom end of the base plate and the top end of the receiving platform are provided with annular grooves. Sliding blocks are slidably connected inside the annular grooves at the bottom end of the base plate and the top end of the receiving platform. Hydraulic cylinders are fixedly connected between the sliding blocks.

[0008] As a further improvement to this technical solution, a groove is provided inside the rotating shaft and extends to its top. A rotating column is slidably connected inside the groove, and the top of the rotating column is fixedly connected to the bottom of the base plate.

[0009] As a further improvement to this technical solution, a reciprocating lead screw is included. The reciprocating lead screw is rotatably connected to the top of the base plate and located in the middle of one side of the C-shaped guardrail. A second servo motor coaxially connected to the top of the C-shaped guardrail is fixedly connected to the top of the C-shaped guardrail. A moving block is connected to the outer nut pair of the reciprocating lead screw. A fixed plate is fixedly connected to one side of the moving block. A pair of guide blocks are fixedly connected to one side of the fixed plate. The guide blocks are slidably connected to the outer sides of two of the C-shaped guardrails. A pair of first short plates are fixedly connected to one side of the fixed plate. A rotating rod is rotatably connected between the inner sides of the pair of first short plates. A baffle is fixedly connected to the outer side of the rotating rod. An adjustment component is provided on the other side of the C-shaped guardrail.

[0010] As a further improvement to this technical solution, the adjustment component includes a second short plate. The other C-shaped guardrail is also equipped with a guide block and a fixing plate. The second short plate is fixedly connected to the other fixing plate. A bidirectional electric push rod is fixedly connected to the top of the second short plate. Both bidirectional electric push rods are fixedly connected to L-shaped plates. The L-shaped plates are slidably connected to the other fixing plate.

[0011] As a further improvement to this technical solution, an inclined block is fixedly connected to one side of the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This stable logistics trolley, when it needs to turn, activates the first servo motor to drive the rotating shaft, causing the loading base plate to rotate to a suitable angle, thus facilitating the turning of the logistics trolley and avoiding collisions that could damage goods when the trolley is manually controlled. When goods need to be layered, first move the baffle to a position parallel to the base plate, then activate the bidirectional electric push rod to move a pair of L-shaped plates in opposite directions to a suitable position to support the baffle. Then activate the second servo motor to drive the reciprocating screw to rotate, causing the moving block to move the baffle up and down, achieving flexible adjustment of the size of the goods. It is flexible to use and has a wide range of applications. When the goods are large, the baffle can be rotated to flip to one side into a vertical position, facilitating the transportation of large items.

[0014] 2. This stable logistics trolley, while requiring turning, also needs to maintain a suitable height between the trolley and the loading / unloading ground. Because annular grooves are provided at the bottom of the base plate and the top of the receiving platform, when the rotating shaft rotates and drives the goods to turn, the rotation of the base plate drives the hydraulic cylinder between the upper and lower sliders to rotate accordingly. At this time, the hydraulic cylinder is activated to raise the base plate, and the rotating column slides up inside the groove, thus satisfying the turning requirement while raising the height of the goods on the logistics trolley, making it easier for workers to load and unload goods, reducing labor intensity, and increasing work efficiency.

[0024] Please see Figures 1-4 As shown, the purpose of this embodiment is to provide a stable logistics trolley, including a base plate 10, with a C-shaped guardrail 1 fixedly connected to the top of the base plate 10 to form a unloading port. The trolley is characterized by further including a receiving platform 2, with rollers fixedly connected to the bottom of the receiving platform 2. A rotating shaft 3 is rotatably connected to the center of the top of the receiving platform 2, and a first servo motor 4 coaxially connected to the rotating shaft 3 is fixedly connected to the bottom of the receiving platform 2. The base plate 10 is positioned above the receiving platform 2 under the connection of the rotating shaft 3, and the base plate 10 rotates synchronously with the rotating shaft 3 under the drive of the first servo motor 4 to adjust the unloading process. The bottom of the base plate 10 and the top of the receiving platform 2 are both provided with annular grooves 5. Sliding blocks 6 are slidably connected inside the annular grooves 5 at the bottom of the base plate 10 and the top of the receiving platform 2. Hydraulic cylinders 7 are fixedly connected between the sliding blocks 6. A sliding groove 8 is provided inside the rotating shaft 3 and extends to its top. A rotating column 9 is slidably connected inside the sliding groove 8. The top of the rotating column 9 is fixedly connected to the bottom of the base plate 10. An inclined block 22 is fixedly connected to one side of the base plate 10. When a fully loaded logistics trolley is manually turned, its heavy weight makes it difficult to maintain stable control during the turning process. The entire vehicle body sometimes drifts and collides with surrounding objects, causing damage to the goods. When the logistics trolley needs to turn, the first servo motor 4 is activated to drive the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the rotating column 9 to rotate and the base plate 10 to rotate, so that the goods follow the rotating shaft 3 to rotate to a suitable angle, thereby facilitating the turning of the logistics trolley and avoiding collisions and damage to the goods when the direction of movement of the logistics trolley is manually controlled. When turning is required, it is also necessary to keep the logistics trolley at a suitable height from the loading and unloading ground. Since the bottom end of the base plate 10 and the top end of the receiving platform 2 are both provided with annular grooves 5, when the rotating shaft 3 rotates and drives the goods on the base plate 10 at the top of the rotating column 9 to turn, the rotation of the base plate 10 drives the hydraulic cylinder 7 between the upper slider 6 and the lower slider 6 to rotate. At this time, the hydraulic cylinder 7 is activated to rise, causing the base plate 10 to rise, so that the rotating column 9 slides and rises inside the groove 8, which satisfies the turning requirement and raises the height of the goods on the logistics trolley, making it easier for the staff to load and unload the goods. The addition of the tilting block 22 makes it easier for the staff to operate, reduces labor intensity, and increases work efficiency.

[0025] The system includes a reciprocating lead screw 11, which is rotatably connected to the top of the base plate 10 and located in the middle of one side of the C-shaped guardrail 1. A second servo motor 12, coaxially connected to the top of the C-shaped guardrail 1, is fixedly connected to the top of the C-shaped guardrail 1. A moving block 13 is connected to the outer nut pair of the reciprocating lead screw 11. A fixed plate 14 is fixedly connected to one side of the moving block 13. A pair of guide blocks 15 are fixedly connected to one side of the fixed plate 14. The guide blocks 15 are slidably connected to the outer sides of two of the C-shaped guardrails 1. A pair of first short plates 16 are fixedly connected to one side of the fixed plate 14. A rotating rod 17 is rotatably connected between the inner sides of 16, and a baffle 18 is fixedly connected to the outer side of the rotating rod 17. An adjustment assembly is provided on the other C-shaped guardrail 1, which includes a second short plate 19. The other C-shaped guardrail 1 is also equipped with a guide block 15 and a fixing plate 14. The second short plate 19 is fixedly connected to the other fixing plate 14. A bidirectional electric push rod 20 is fixedly connected to the top of the second short plate 19. Both bidirectional electric push rods 20 are fixedly connected to L-shaped plates 21. The L-shaped plates 21 are slidably connected to the other fixing plate 14. Existing layered devices are generally fixedly installed. On a logistics trolley, the height of the layering device cannot be adjusted according to the size of the goods; it can only store goods of a certain volume, resulting in a narrow range of applications and insufficient flexibility. When it is necessary to layer goods, first move the baffle 18 to a position parallel to the base plate 10. Then, activate the bidirectional electric push rod 20 to move a pair of L-shaped plates 21 in opposite directions to a suitable position to support the baffle 18. Simultaneously, activate the second servo motor 12 to rotate the reciprocating screw 11, causing the moving block 13 to move the fixed plate 14 up and down. At this time, the guide on the fixed plate 14... The guide block 15 slides up and down on the C-shaped guardrail 1. At the same time, the rotating rod 17 on the first short plate 16 on one side of the fixed plate 14 drives the baffle 18 and the guide block 15 and fixed plate 14 on the other side of the C-shaped guardrail 1 to move together. It can be flexibly adjusted according to the size of the goods, making it more flexible to use and with a wider range of applications. When the goods are large, the L-shaped plate 21 on the bidirectional electric push rod 20 is first opened to move to both sides to release the support of the baffle 18. At this time, the baffle 18 is rotated to flip to one side and become vertical, expanding the space and facilitating the transportation of large goods.

[0026] Working principle: When the logistics trolley needs to turn, the first servo motor 4 is activated to drive the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the rotating column 9 to rotate and the base plate 10 to rotate, so that the goods follow the rotating shaft 3 to rotate to a suitable angle, thus facilitating the turning of the logistics trolley and avoiding collisions and damage to the goods when the direction of movement of the logistics trolley is manually controlled. When turning is required, it is also necessary to keep the logistics trolley at a suitable height from the loading and unloading ground. Because the bottom end of the base plate 10 and the top end of the receiving platform 2 are both provided with annular grooves 5, when the rotating shaft 3 rotates and drives the goods on the base plate 10 at the top of the rotating column 9 to turn, the rotation of the base plate 10 drives the hydraulic cylinder 7 between the upper slider 6 and the lower slider 6 to rotate. At this time, the hydraulic cylinder 7 is activated to rise, causing the base plate 10 to rise, so that the rotating column 9 slides and rises inside the groove 8, satisfying the turning requirement and raising the height of the goods on the logistics trolley, making it easier for the staff to load and unload the goods. The addition of the tilting block 22 further facilitates the operation. This design allows for easier operation, reducing labor intensity and increasing work efficiency. When goods need to be layered, the baffle 18 is first moved to a position parallel to the base plate 10. The bidirectional electric push rod 20 is then activated to move a pair of L-shaped plates 21 in opposite directions to a suitable position to support the baffle 18. Simultaneously, the second servo motor 12 is activated to rotate the reciprocating screw 11, causing the moving block 13 to move the fixed plate 14 up and down. At this time, the guide block 15 on the fixed plate 14 slides up and down on the C-shaped guardrail 1. At the same time, the rotating rod 17 on the first short plate 16 on one side of the fixed plate 14 drives the baffle 18 and the guide block 15 on the other side of the C-shaped guardrail 1 to move together with the fixed plate 14. This design allows for flexible adjustment according to the size of the goods, making it more flexible to use and with a wider range of applications. When the goods are large, the L-shaped plates 21 on the bidirectional electric push rod 20 are first activated to move to both sides to release the support of the baffle 18. At this time, the baffle 18 is rotated and flipped to one side to a vertical position, expanding the space and facilitating the transportation of large goods.
