Abstract
Description
Technical Field
[0001] This utility model belongs to the field of warehouse industrial transportation, and in particular relates to a standardized interface between a warehouse industrial transportation vehicle and a shelf. Background Technology
[0002] Industrial handling vehicles are widely used in ports, railway stations, airports, freight yards, factory workshops, warehouses, distribution centers, and other locations for loading, unloading, and handling palletized goods within ship holds, carriages, and containers. They are indispensable equipment in palletized and containerized transport. Industrial handling vehicles typically consist of a mobile chassis, a cargo-carrying platform, and a cargo-lifting mechanism. The mobile chassis moves the goods, and the platform lifting mechanism raises or lowers the cargo-carrying platform, enabling loading, unloading, and handling operations. However, when pushing goods onto shelves, currently, manual labor or a push-pull mechanism can be used. Both methods require improved reliability of the connection between the cargo-carrying platform and the shelf panels; especially when pushing large goods, the connection point is prone to swaying or misalignment.

Detailed Implementation
[0026] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0028] like Figures 1 to 3 As shown, a standardized interface between a warehouse industrial transport vehicle and a shelf is provided. Based on an industrial transport vehicle 1, the industrial transport vehicle 1 includes a cargo platform 3 and a lifting mechanism 2, which drives the cargo platform 3 to rise or fall. The standardized interface includes a platform interface 4 set on the cargo platform 3 and a shelf interface 5 set on the shelf 7.
[0029] The platform interface 4 includes docking teeth 11 and overlapping mechanism. The end face of the cargo platform 3 is provided with docking teeth 11, which protrude outward. There are multiple docking teeth 11, which are spaced apart from each other. The overlapping mechanism is provided below the docking teeth 11. The overlapping mechanism includes an electric cylinder and an overlapping arm 14. The front end of the overlapping arm 14 is provided with an overlapping hook 15. The electric cylinder drives the overlapping arm 14 to reciprocate in the horizontal direction.
[0030] like Figure 3 As shown, the shelf interface 5 includes a mating tooth groove 12, an overlapping groove 13, and a positioning block 14. The mating tooth groove 12 is provided on the end face of the shelf panel 6. There are multiple mating tooth grooves 12, and each of the multiple mating tooth grooves 12 corresponds to a mating tooth 11. The mating tooth 11 can be inserted into the mating tooth groove 12. The front face of the shelf 7 has an overlapping groove 13. A positioning block 16 is provided at the bottom of the overlapping groove 13. The overlapping groove 13 corresponds to the overlapping arm 14. The overlapping hook 15 corresponds to the positioning block 16. The overlapping arm 14 can extend into the overlapping groove 13, and the overlapping hook 15 can hook onto the positioning block 16.
[0031] This utility model discloses a standardized interface between a warehouse industrial transport vehicle and a shelf. By setting a platform interface 4 and a shelf interface 5 on the warehouse shelf and the industrial transport vehicle respectively, a standardized interface is formed to connect the loading platform 3 of the industrial transport vehicle 1 with the warehouse shelf, which facilitates the pushing of goods to the shelf. The horizontal direction is limited by the mating teeth 11 being inserted into the mating tooth groove 12. The overlapping arm 14 extends into the overlapping groove 13 and the overlapping hook 15 can be hooked onto the positioning block 16.
[0032] like Figure 4 As shown, the overlapping slot 13 includes a bottom surface 27, a side wall 25, and a top surface 23. A positioning block 16 is disposed on the bottom surface 17. The positioning block 16 and the top surface 23 form a first space 24 for accommodating the overlapping arm 14 and the overlapping hook 15. The positioning block 16 and the side wall 25 form a second space 26 for accommodating the insertion of the overlapping hook 15. It can be installed on warehouse shelves, with a concave structure to reduce space occupation.
[0033] like Figure 5As shown, the electric cylinder includes a motor 33, a cylinder body 10, a guide rail 30, a push rod 32, and a slider 31. The motor 33 is connected to the cylinder body 10, and the push rod 32 is installed inside the cylinder body 10. The guide rail 30 is arranged horizontally, and the slider 31 is mounted on the guide rail 30. The slider 31 is connected to the overlapping arm 14. The motor drives the push rod, which in turn drives the slider 31 to reciprocate along the guide rail 30, thereby realizing the reciprocating horizontal movement of the overlapping arm 14.
[0034] The working steps of a standardized interface between a warehouse industrial transport vehicle and a shelf include: First, the industrial transport vehicle 1 transports goods to the shelf, and the lifting mechanism 2 drives the loading platform 3 to rise; Second, the electric cylinder is activated to drive the slider to move forward, causing the overlapping arm 14 to extend into the overlapping groove 13, while the docking tooth 11 is located above the corresponding docking tooth groove 12; The lifting mechanism 2 drives the loading platform 3 to descend, the overlapping hook 15 hooks onto the positioning block 16, and the docking tooth 11 can be engaged with the docking tooth groove 12 from above in a vertical direction, completing the docking between the loading platform and the shelf.
[0035] like Figure 5 As shown, a first limit sensor 34 and a second limit sensor 36 are provided on the guide rail 30, and the first limit sensor 34 and the second limit sensor 36 are spaced apart along the moving direction of the slider 31. A proximity sensor 37 is provided on the overlapping arm 14, and the proximity sensor 37 is located close to the overlapping hook 15. A PLC controller is also included, with the signal output terminal of the PLC controller connected to the lifting mechanism 2 and the motor 33. The first limit sensor, the second limit sensor, and the proximity sensor are respectively connected to the signal input terminal of the controller.
[0036] The first limit sensor 34 and the second limit sensor 36 are photoelectric sensors, used to detect the extension and retraction range of the slider, respectively, to ensure that the slider moves within a safe range. The proximity sensor 37 is used to detect whether the hook 15 is close to the positioning block 16; preferably, the proximity sensor 37 is an inductive proximity switch. Based on the signals collected by the first limit sensor 34, the second limit sensor 36, and the proximity sensor 37, the PLC controller controls the operation of the lifting mechanism 2 and the motor 33, achieving automatic control of the lifting mechanism 2 and the motor 33 to complete the docking action.
[0037] like Figure 2 As shown, there are two or four mating teeth 11 and two or four mating tooth grooves 12. The horizontal cross-section of the mating teeth 11 and the mating tooth grooves 12 is generally triangular. This facilitates the industrial transport vehicle 1 to approach from the front of the shelf, and when the lifting mechanism 2 lowers the loading platform 3 so that the hook 15 engages with the positioning block 16, the mating teeth 11 can be vertically engaged into the mating tooth grooves 12 from above.
[0038] like Figure 3As shown, the distance between the docking tooth 11 and the loading platform 3 is equal to the distance between the docking tooth groove 12 and the shelf 6. When the docking tooth 11 and the docking tooth groove 12 are engaged, the loading platform 3 and the shelf 6 are in the same plane. This ensures that the transport vehicle and the loading platform can fully mesh when docked.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
