Abstract
Description
Technical Field
[0001] This utility model relates to the field of cargo handling technology, specifically to a cargo loading and unloading mechanism and a cargo handling vehicle. Background Technology
[0002] Cargo handling refers to the short-distance movement, loading, unloading, stacking, and sorting of goods using human or mechanical equipment to achieve spatial transfer or relocation of goods in warehousing, transportation, and production processes. This process typically does not alter the physical or chemical properties of the goods, but focuses on logistics efficiency and safety.
[0003] In existing technologies, the loading and transportation of small goods generally involves manual handling to move the goods onto the floor of the truck bed, followed by manual arrangement of the items inside the truck bed. Alternatively, some workers use forklifts to move the goods to the rear of the truck bed, and then manually arrange the goods. Both of these methods are labor-intensive, costly, and slow, resulting in low efficiency, inconvenience, and poor economy. Utility Model Content
[0004] This utility model provides a cargo loading and unloading mechanism and a cargo handling vehicle, which solves the problems of existing cargo handling methods, such as high labor intensity, excessive cost, slow manual handling speed, low efficiency, poor convenience and economy.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A cargo handling mechanism includes a support body and further includes:
[0007] platform;
[0008] A lifting and transporting mechanism is mounted on a support body. The lifting and transporting mechanism includes a drive source and a lifting linkage assembly mounted on the support body with its free end hinged to the platform. The lifting linkage assembly can be driven by the drive source to drive the platform to extend or retract horizontally along the support body.
[0009] Preferably, the cargo handling mechanism further includes a horizontal moving mechanism for driving the lifting and handling mechanism to translate along the support body. The horizontal moving mechanism includes a moving part disposed on the side of the support body for mounting the lifting and handling mechanism and a power component for driving the moving end of the moving part to translate.
[0010] Preferably, the movable component includes a guide rail fixedly mounted on the top of the support and a rack slidably connected to the guide rail.
[0011] Preferably, the power assembly includes a motor fixedly connected to one side of the top of the support body via a plate and a gear disposed at the output end of the motor, the gear meshing with a rack.
[0012] Preferably, the driving source is an electric actuator, and the fixed end of the electric actuator is hinged to the rack.
[0013] Preferably, the lifting linkage assembly includes a parallel linkage assembly hinged to the rack, the parallel linkage assembly including two parallel hinged to the rack sidewalls, a first linkage and a third linkage, and a second linkage assembly hinged to the end of the first linkage and the third linkage away from the rack.
[0014] Preferably, the output end of the drive source is hinged to the middle of the first connecting rod.
[0015] Preferably, the second linkage group includes a second link distributed parallel to the rack and hinged to the first link and the third link, and a connecting rod integrally formed at the end of the second link and extending downward at an angle.
[0016] Preferably, the connecting rod includes a fourth link and a fifth link extending outward from the end of the second link, and a sixth link fixedly disposed between the fourth link and the fifth link.
[0017] A cargo handling vehicle, wherein the cargo handling vehicle is equipped with a cargo loading and unloading mechanism as described above in the cargo compartment.
[0018] As can be seen from the above technical solutions, this utility model has the following beneficial effects:
[0019] 1. In this utility model, during the extension and retraction process, the drive source can drive the lifting linkage group to move so as to drive the platform to extend or retract horizontally along the support body. This makes it convenient to load goods when the platform is extended and convenient for workers to unload goods from the platform when the platform is retracted above the support body. This solves the problems of high labor intensity, high cost, slow speed, low efficiency, poor convenience and economy of existing methods of handling goods.
[0020] 2. In this utility model, a horizontal moving mechanism is also provided on the support body. The motor drives the gear to rotate, and the gear drives the rack to move horizontally along the support body. This drives the drive source on the rack and the lifting linkage assembly to extend or retract horizontally along the support body. This further enables the platform to extend or retract, thereby further improving the convenience of loading and unloading goods from the platform.
[0021] 3. In this utility model, the lifting linkage assembly includes a parallel linkage assembly hinged to a rack. The parallel linkage assembly includes a first link, a third link, and a second link group. The second link group includes a second link and a connecting rod. The connecting rod includes a fourth link, a fifth link, and a sixth link. The second link, fourth link, fifth link, and sixth link are integrally formed. Thus, under the drive of the drive source, the second link, the connecting rod, and the platform self-support body can be driven to extend or retract through the first link and the third link. Since the second link, fourth link, fifth link, and sixth link are fixedly integrated, and the platform is fixedly set at the bottom of the sixth link, under the drive of the first link and the third link, it can be ensured that the platform at the bottom of the connecting rod can always remain in a horizontal state during extension and retraction.

[0028] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.
[0029] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: (Refer to...) Figure 1A cargo handling mechanism includes a support body 10, a platform 20, and a lifting and handling mechanism. The support body 10 is a plate-like structure that provides a supporting foundation. The platform 20 serves as the foundation for cargo transfer. The lifting and handling mechanism is mounted on the support body 10. Furthermore, the lifting and handling mechanism includes a drive source 310 and a lifting linkage assembly. The lifting linkage assembly is mounted on the support body, and its free end is hinged to the platform 20. In use, the lifting linkage assembly can be driven by the drive source to extend or retract the platform horizontally along the support body 10. In this way, workers can use this extendable platform to automate the loading and unloading of cargo, solving the problems of high labor intensity and excessive cost in existing cargo handling methods. It also solves the problems of slow speed, low efficiency, poor convenience, and poor economy of existing manual handling.
[0030] Furthermore, when the platform 20 extends or retracts along the support body 10, in order to facilitate loading and unloading of materials onto and off the platform 20, the cargo handling mechanism further includes a horizontal moving mechanism for driving the lifting and handling mechanism to translate along the support body. The horizontal moving mechanism includes a moving component and a power component. The moving component is located on the side of the support body 10 and is used to install the lifting and handling mechanism. The power component is used to drive the moving end of the moving component to move horizontally.
[0031] Reference Figure 2 Furthermore, the movable component includes a guide rail 411 and a rack 412. The guide rail 411 is fixedly mounted on the top of the support body 10, and the rack 412 is slidably connected to the guide rail 411. The guide rail 411 is a dovetail-shaped long groove, and its bottom can be fixed to the support body 10 through bolt holes. Lubricating oil is applied to the dovetail-shaped long groove. The upper end of the rack 412 is toothed, and the lower part is a dovetail-shaped protrusion, which works in conjunction with the dovetail-shaped long groove.
[0032] Furthermore, the power assembly includes a motor 421 and a gear 422. The motor 421 is fixedly connected to the top side of the support body 10 via a plate. The gear 422 is fixedly disposed at the output end of the motor 421 and meshes with the rack 412.
[0033] In the specific implementation process, the device is first installed in Figure 3 Position the goods and move them onto platform 20. Then turn on the switch of drive source 310. The drive source retracts, transferring platform 20 to the desired location. Figure 4As shown, platform 20 is now positioned on the cargo compartment. Turning on motor 421 causes it to rotate, which in turn rotates gear 422, further moving rack 412 to the right. This moves the entire lifting linkage assembly and the cargo to any position on the right, allowing staff to organize the items. After organization, motor 421 reverses, causing gear 422 to reverse as well, further moving rack 412 to the left. This moves the entire lifting linkage assembly to the rear of the vehicle, extending drive source 310 and transferring platform 20 to... Figure 3 As shown in the diagram. Furthermore, multiple motors 421 and gears 422 can be installed on the support 10 to prevent the rack 412 from being too short to move to the target position.
[0034] In some embodiments, the drive source 310 is an electric push rod, and the fixed end of the electric push rod is hinged to the rack 412.
[0035] In some embodiments, the lifting linkage assembly includes a parallel linkage assembly hinged to the rack 412, so that the parallel linkage assembly can be driven to extend or retract along the support body 10 under the action of the drive source 310, thereby realizing the vertical transport of goods.
[0036] Reference Figure 2 , Figure 5Furthermore, the parallel linkage assembly includes a first link 321, a third link 322, and a second link group. The first link 321 and the third link 322 are arranged parallel to each other, and their bottom ends are hinged to the side wall of the rack 412. Simultaneously, the output end of the drive source 310 is hinged to the middle of the first link 321. The second link group includes a second link 323 and a connecting rod. Specifically, the second link 323 is distributed parallel to the rack 412, and is hinged to the ends of the first link 321 and the third link 322 away from the rack 412. The connecting rod is integrally formed at the end of the second link and extends obliquely downward from the end of the second link. The connecting rod includes a fourth link 324 and a fifth link 325 radiating outward from the end of the second link 323, and a fourth link 324 fixedly disposed between the fourth and fifth links. The six-link 326 forms a connecting rod with the fourth, fifth, and sixth links, which extend outward from the second link in an integrated structure. This allows the platform to be easily fixed at the bottom of the connecting rod. The connecting rod is then combined with the second link to form a second link group with an integrated structure. At this point, the rack 412, the first link 321, the third link 322, and the second link 323 form a parallel four-bar linkage. When the drive source 310 extends or retracts, the free end of the parallel four-bar linkage, that is, the end where the second link 323 is located, can extend or retract along the support body 10. Specifically, when extended, the platform can be lowered horizontally to the lower side of the support body 10 to facilitate loading goods onto the platform 20. When the platform is retracted above the support body 10, it is convenient for workers to unload goods from the platform 20, thereby realizing automated assisted handling of goods.
[0037] It should be noted that, referring to Figure 5 The second link 323, the fourth link 324, the fifth link 325 and the sixth link 326 are fixed as one piece, and the platform 20 is fixedly set at the bottom of the sixth link. In this way, when the first link and the third link swing along the rack under the drive of the drive source, the second link can drive the connecting rod and the platform at the bottom to always keep in a horizontal state during extension and retraction.
[0038] This embodiment also provides a cargo handling vehicle. The cargo handling vehicle is equipped with the aforementioned cargo loading and unloading mechanism. By setting the aforementioned handling mechanism in the cargo handling vehicle, during use, the platform 20 at the free end of the parallel linkage assembly can be driven to extend or retract along the support body 10 by the cooperation of the drive source 310 and the lifting linkage assembly, so as to realize the automated loading and unloading of goods, improve work efficiency and reduce workload.
[0039] In use, the drive source 310 extends the platform 20 along the support body 10, and the goods are transported onto the platform 20. Then, the drive source 310 is turned on, and the drive source retracts, moving the platform 20 back to a position above the support body 10. At this time, the platform 20 is already on the carriage. The motor 421 is turned on, and the motor rotates, driving the gear 422 to rotate, which in turn drives the rack 412 to move to the right, moving the entire lifting linkage assembly and the goods to any position on the right. Then, the staff can organize the items. After the organization is completed, the motor 421 reverses, driving the gear 422 to reverse, which in turn drives the rack 412 to move to the left, moving the entire lifting linkage assembly to the rear of the vehicle, causing the drive source 310 to extend, and transferring the platform 20 to the extended support body 10 for the next loading and unloading.
[0040] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
