Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, specifically a warehouse cargo handling equipment. Background Technology

[0002] Warehouse handling equipment refers to mechanical equipment used within warehouses for moving, lifting, and stacking goods. This type of equipment can improve warehouse operational efficiency, reduce manual labor intensity, and facilitate the automation of warehouse management.

[0003] Existing warehousing and cargo handling equipment can be referenced from Chinese Utility Model Patent Publication No. CN221623770U, which discloses a warehousing and cargo handling device including a base. The base has an internal mounting compartment, and the mounting compartment contains a connecting seat. A connecting shaft is rotatably connected inside the connecting seat, and a roller sleeve is rotatably connected to the outer surface of the connecting shaft. The base has an internal mounting groove, and the roller sleeve is rotatably connected inside the mounting groove. An electric push rod is mounted on the inner bottom wall of the mounting compartment, and an adjusting plate is mounted at the output end of the electric push rod. The adjusting plate has a connecting through hole, and a limit rod is slidably connected inside the connecting through hole. This warehousing and cargo handling device, through the coordinated arrangement of the electric push rod, adjusting plate, roller sleeve, limit rod, and first spring, achieves the effects of facilitating the movement of goods on the handling equipment and conveniently and quickly limiting the movement of goods.

[0004] The aforementioned device is effective, but it still has some drawbacks: By controlling the rotation of the first motor, the adjusting screw rotates, causing the support frame and the limiting plate to slide down the limiting slide bar until the limiting plate abuts against the upper surface of the goods. The securing effect of the limiting plate on the goods is relatively limited. If the height or shape of the goods is inconsistent, especially when the height difference is significant, a single limiting plate may not effectively provide sufficient pressure to all goods to ensure their stability during handling. For lighter or irregularly shaped goods, this simple upper and lower limiting method may be insufficient to prevent movement. Utility Model Content

[0005] The purpose of this utility model is to provide a warehouse cargo handling device with the advantages of flexible adjustment and good cargo fixing effect. Through the combination of airbags and abutment rods, it can flexibly adapt to cargo of various shapes and sizes, provide good fixing effect, and avoid cargo damage caused by direct pressure. Due to the adoption of an adjustable support mechanism, the device shows higher applicability and safety when handling irregular or fragile items.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a warehouse cargo handling device, comprising a base and brake casters rotatably disposed at the four corners of its bottom, wherein a handrail is fixedly connected to the top right side of the base.

[0007] Support shells are fixedly connected to the front and rear surfaces of the base. Two support shells are arranged parallel to the base. Guide grooves are opened on the left and right sides of the top of the two support shells. Mounting shells are fixedly connected to the right side of the two support shells. Rectangular shells are slidably connected to the top left and right sides of the base. Airbags are provided inside the two rectangular shells. Multiple abutment rods are equidistantly slidably connected to the bottom of the two airbags. The multiple abutment rods are perpendicular to the top of the base. Positioning shells are fixedly connected to the top of the two rectangular shells. Air pumps are fixedly connected to the bottom of the inner walls of the two positioning shells. The air outlet of the air pump extends to the outside of the positioning shell and is fixedly connected to it. A connecting pipe is fixedly connected to the air pump's suction end. The end of the connecting pipe away from the air pump passes through the positioning shell and the rectangular shell and is fixedly connected to the top of the airbag.

[0008] As a preferred embodiment of the warehousing and cargo handling equipment of this utility model, both of the two support shells are rotatably connected to horizontally arranged bidirectional threaded rods. The two bidirectional threaded rods are symmetrically arranged on the front and rear sides of the base, and are parallel to the base. The right ends of the two bidirectional threaded rods penetrate the support shell and extend into the mounting shell for rotatable connection.

[0009] As a preferred embodiment of the storage and handling equipment of this utility model, the left ends of the two bidirectional threaded rods are rotatably connected to the left side of the inner wall of the support shell, and a central block is rotatably connected to the center of the surface of the two bidirectional threaded rods, and the central block is fixedly installed at the center of the inner wall of the support shell.

[0010] As a preferred embodiment of the warehousing and cargo handling equipment of this utility model, limit rods are fixedly connected to the left and right sides of the inner walls of the two support shells, and worm gears are fixedly sleeved on the inner surfaces of the two bidirectional threaded rods. A protective cover is fixedly connected to the center of the right side of the base.

[0011] As a preferred embodiment of the warehousing and cargo handling equipment of this utility model, a dual-axis motor is fixedly connected to the bottom of the inner wall of the protective cover. The output ends of the dual-axis motor on both sides extend to the outside of the protective cover and are rotatably connected thereto. Worms are fixedly connected to the output ends of the dual-axis motor on both sides. The bottom of the two worms is meshed with the top of the two worm wheels.

[0012] As a preferred embodiment of the storage and handling equipment of this utility model, threaded sleeves are threadedly connected to the left and right sides of the two bidirectional threaded rods. The threaded sleeves are slidably connected to the limiting rods. The tops of the two threaded sleeves located inside the same support shell are fixedly connected to connecting rods. The tops of the two connecting rods extend to the top of the support shell and are slidably connected to the inner wall of the guide groove.

[0013] As a preferred embodiment of the warehousing and cargo handling equipment of this utility model, the two threaded sleeves located on the left and right sides inside the same support shell move from the left and right ends of the support shell towards its center. The tops of the two connecting rods located on the same side of the base are rotatably connected to inclined electric push rods, and the telescopic ends of the tops of the two inclined electric push rods are rotatably connected to the same rectangular shell.

[0014] As a preferred embodiment of the warehousing and cargo handling equipment of this utility model, the two rectangular shells are arranged parallel to the base, and horizontally arranged airbags are fixedly connected to the inner walls of the two rectangular shells. The two airbags are arranged parallel to the base, and multiple vertically arranged abutment rods are fixedly connected to the bottom of the two airbags. The bottom of the multiple abutment rods penetrates the airbags and extends to the bottom of the rectangular shells and slides to connect with them. Multiple sealing rings are equidistantly connected to the bottom of the two airbags, and the inner walls of the multiple sealing rings are slidably connected to the surfaces of the multiple abutment rods.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. When adjusting the distance between two rectangular shells to accommodate goods of different widths, this utility model first starts the dual-axis motor. The rotation of the dual-axis motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate, causing the bidirectional threaded rod to start rotating. When the bidirectional threaded rod rotates, the threaded sleeve slides along the limiting rod and moves towards the center or both ends of the support shell, thereby adjusting the position of the rectangular shell. Each threaded sleeve has a connecting rod fixedly connected to its top. The top of the connecting rod extends above the top of the support shell and slides between it and the inner wall of the guide groove. The function of the connecting rod is to ensure that the rectangular shell can move smoothly along the guide groove and be precisely adjusted to the required position.

[0017] 2. This utility model, by controlling the extension and retraction length of the electric push rod, can adjust the angle and height of the rectangular shell to better adapt to goods of different heights and shapes. When the height of the goods needs to be adjusted or additional support is required, the air pump inflates or deflates the airbag, changing the degree of inflation. When the airbag is inflated, it pushes the abutment rod downwards until it contacts and supports the goods. The sealing ring ensures that the airbag does not leak during inflation or deflation, while allowing the abutment rod to move smoothly up and down, providing stable support for the goods. Through this design, this warehouse goods handling equipment can efficiently and flexibly adapt to goods of various sizes and types, significantly improving the safety and efficiency of the handling process, and greatly reducing the risks and complexity of manual operation.

[0023] Please see Figures 1-4 A warehouse cargo handling device includes a base 1 and brake casters 2 rotatably mounted at the four corners of its bottom. A handrail 3 is fixedly connected to the top right side of the base 1.

[0024] The base 1 serves as the basic structure of the entire equipment. Braked casters 2 are installed at the four corners of the bottom to facilitate the movement and positioning of the equipment. A handrail 3 is provided on the right side for easy operation by the operator.

[0025] Furthermore, support shells 4 are fixedly connected to the front and rear surfaces of the base 1. The two support shells 4 are arranged parallel to the base 1. Guide grooves 401 are opened on the left and right sides of the top of the two support shells 4. Mounting shells 402 are fixedly connected to the right side of the two support shells 4. Rectangular shells 12 are slidably connected to the left and right sides above the base 1. Airbags 13 are provided inside the two rectangular shells 12. Multiple abutment rods 14 are equidistantly slidably connected to the bottom of the two airbags 13. The multiple abutment rods 14 are arranged perpendicular to the top of the base 1. Positioning shells 15 are fixedly connected to the top of the two rectangular shells 12. Air pumps 16 are fixedly connected to the bottom of the inner wall of the two positioning shells 15. The air outlet of the air pump 16 extends to the outside of the positioning shell 15 and is fixedly connected to it. The air suction end of the air pump 16 is fixedly connected to the connecting pipe 17. The end of the connecting pipe 17 away from the air pump 16 passes through the positioning shell 15 and the rectangular shell 12 and is fixedly connected to the top of the airbag 13.

[0026] A rectangular shell 12 is located on the left and right sides above the base 1 and is slidably connected to it. It contains an airbag 13 inside the rectangular shell 12. Multiple abutment rods 14, equidistantly arranged perpendicular to the top of the base 1, are slidably connected to the bottom of the airbag 13. By inflating or deflating the airbag 13 with an air pump 16, the height of the abutment rods 14 can be adjusted, thereby effectively supporting and securing goods of different heights. A positioning shell 15 is fixed to the top of the rectangular shell 12 and contains an air pump 16. The air pump 16 is connected to the airbag 13 via a connecting pipe 17. The air pump 16 is responsible for supplying or deflating the airbag 13, thereby controlling its expansion or contraction and adjusting the position of the abutment rods 14 to ensure the stability of the goods.

[0027] Furthermore, both support shells 4 are rotatably connected to horizontally arranged bidirectional threaded rods 5. The two bidirectional threaded rods 5 are symmetrically arranged on the front and rear sides of the base 1, and are parallel to the base 1. The right ends of the two bidirectional threaded rods 5 penetrate the support shell 4 and extend into the mounting shell 402 for rotatable connection.

[0028] Both support shells 4 are rotatably connected to horizontally arranged bidirectional threaded rods 5. These two bidirectional threaded rods 5 are symmetrically arranged on the front and rear sides of the base 1 and are parallel to the base 1. This design allows components such as rectangular shells 12 on the bidirectional threaded rods 5 to move along the bidirectional threaded rods 5, thereby adapting to goods of different widths.

[0029] Furthermore, the left ends of the two bidirectional threaded rods 5 are rotatably connected to the left side of the inner wall of the support shell 4, and a center block 501 is rotatably connected to the center of the surface of the two bidirectional threaded rods 5. The center block 501 is fixedly installed at the center of the inner wall of the support shell 4.

[0030] The center block 501 is rotatably installed at the center of the bidirectional threaded rod 5 and is fixedly connected to the inner wall of the support shell 4. This design can effectively enhance the structural stability of the bidirectional threaded rod 5 and prevent it from bending or deforming during use, especially when subjected to large loads.

[0031] Furthermore, limit rods 7 are fixedly connected to the left and right sides of the inner walls of the two support shells 4, and worm gears 8 are fixedly fitted on the inner surfaces of the two mounting shells 402. A protective cover 101 is fixedly connected to the center of the right side of the base 1.

[0032] The limit rod 7 provides guidance and support for the components on the bidirectional threaded rod 5, ensuring that these components maintain linear motion during movement and avoiding offset or tilting, thereby improving the accuracy of operation.

[0033] Furthermore, a dual-axis motor 10 is fixedly connected to the bottom of the inner wall of the protective cover 101. The output ends of the dual-axis motor 10 extend to the outside of the protective cover 101 and are rotatably connected thereto. Worms 9 are fixedly connected to the output ends of the dual-axis motor 10 on both sides. The bottom of the two worms 9 is meshed with the top of the two worm wheels 8.

[0034] When it is necessary to adjust the distance between the two rectangular shells 12 to accommodate goods of different widths, the dual-axis motor 10 is activated. The rotation of the dual-axis motor 10 drives the worm gears 9 on both sides to rotate, and the worm gears 9 then drive the worm wheel 8 that meshes with them, thereby causing the bidirectional threaded rod 5 to rotate. Due to the design of the bidirectional threaded rod 5, this causes the rectangular shells 12 to slide along the limiting rod 7, achieving synchronous and precise distance adjustment.

[0035] Furthermore, threaded sleeves 6 are threadedly connected to the left and right sides of the two bidirectional threaded rods 5. The threaded sleeves 6 are slidably connected to the limiting rods 7. The tops of the two threaded sleeves 6 located inside the same support shell 4 are fixedly connected to connecting rods 601. The tops of the two connecting rods 601 extend to the top of the support shell 4 and are slidably connected to the inner wall of the guide groove 401.

[0036] Two threaded sleeves 6 located inside the same support shell 4 are fixedly connected to their tops with connecting rods 601. The connecting rods 601 extend above the top of the support shell 4 and slide between the connecting rods and the inner wall of the guide groove 401. The main function of the connecting rods 601 is to convert the linear motion of the threaded sleeves 6 into the horizontal movement of the rectangular shell 12, ensuring that the rectangular shell 12 can be precisely adjusted along the guide groove 401.

[0037] Furthermore, the two threaded sleeves 6 located on the left and right sides inside the same support shell 4 move from the left and right ends of the support shell 4 toward its center. The tops of the two connecting rods 601 on the same side of the base 1 are rotatably connected to inclined electric push rods 11, and the telescopic ends of the tops of the two inclined electric push rods 11 are rotatably connected to the same rectangular shell 12.

[0038] The top telescopic ends of the two inclined electric push rods 11 are rotatably connected to the same rectangular shell 12. The electric push rods 11 can adjust the height and angle of the rectangular shell 12 as needed, so as to better adapt to goods of different heights and shapes.

[0039] Furthermore, two rectangular shells 12 are arranged parallel to the base 1. Horizontally arranged airbags 13 are fixedly connected to the inner walls of both rectangular shells 12. The two airbags 13 are arranged parallel to the base 1. A plurality of vertically arranged abutment rods 14 are fixedly connected to the bottom of the two airbags 13. The bottom of the plurality of abutment rods 14 penetrates the airbags 13 and extends to the bottom of the rectangular shells 12, where they are slidably connected. A plurality of sealing rings 130 are equidistantly connected to the bottom of the two airbags 13. The inner walls of the plurality of sealing rings 130 are slidably connected to the surfaces of the plurality of abutment rods 14.

[0040] By adjusting the air pressure inside the airbag 13, its rigidity and height can be changed, thereby providing appropriate support for the goods. The abutment rods 14 move up and down when the airbag 13 is inflated or deflated, directly contacting and supporting the goods to ensure their stability during handling. The inner wall of the sealing ring 130 is slidably connected to the surfaces of the multiple abutment rods 14. The main function of the sealing ring 130 is to prevent gas leakage from the airbag 13, while allowing the abutment rods 14 to move freely up and down inside the airbag 13 without affecting its sealing performance. This ensures that the airbag 13 does not lose pressure due to the movement of the abutment rods 14 during inflation or deflation, ensuring the reliability of the system.

[0041] When the distance between the two rectangular shells 12 needs to be adjusted to accommodate goods of different widths, the dual-axis motor 10 is first started. The rotation of the dual-axis motor 10 drives the worm gear 9 to rotate, which in turn drives the worm wheel 8 to rotate, causing the bidirectional threaded rod 5 to start rotating. When the bidirectional threaded rod 5 rotates, the threaded sleeve 6 slides along the limiting rod 7 and moves towards the center or both ends of the support shell 4, thereby adjusting the position of the rectangular shell 12. Each threaded sleeve 6 has a connecting rod 601 fixedly connected to its top. The top of the connecting rod 601 extends above the top of the support shell 4 and slides between it and the inner wall of the guide groove 401. The function of the connecting rod 601 is to ensure that the rectangular shell 12 can move smoothly along the guide groove 401 and be precisely adjusted to the required position.

[0042] By controlling the extension and retraction length of the electric push rod 11, the angle and height of the rectangular shell 12 can be adjusted to better adapt to goods of different heights and shapes. When the height of the goods needs to be adjusted or additional support is required, the air pump 16 inflates or deflates the airbag 13, changing the degree of inflation of the airbag 13. When the airbag 13 is inflated, it pushes the abutment rod 14 downward until it contacts and supports the goods. The sealing ring 130 ensures that the airbag 13 does not leak during inflation or deflation, while allowing the abutment rod 14 to move smoothly up and down, providing stable support for the goods. Through this design, the warehouse cargo handling equipment can efficiently and flexibly adapt to goods of various sizes and types, significantly improving the safety and efficiency of the handling process, and greatly reducing the risks and complexity of manual operation.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
