Description

Technical Field

[0001] This application relates to the field of material handling devices, and in particular to a material handling device. Background Technology

[0002] In the processes of material handling, inventory management, and transportation at railway stations, the complex spatial structure and high personnel mobility pose significant challenges to the safety, flexibility, and efficiency of handling equipment. Currently, hydraulic handcarts have become a common tool for material transportation within stations due to their flexible operation and suitability for navigating narrow spaces.

[0003] However, when faced with heavy cargo, manual loading onto the handcart platform is impossible, necessitating the use of forklifts for assisted loading and unloading. While forklifts provide the necessary lifting capacity, their large size and poor maneuverability make them ill-suited to the complex environment inside the station. They are also prone to collisions with moving passengers, posing significant safety risks. Furthermore, the disruption caused by forklift operations can derail the station's normal operations, negatively impacting passenger flow efficiency and experience. Utility Model Content

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the material handling device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] See Figure 1 and Figure 2 One embodiment of this application provides a material handling device 10, which includes a base 100, a support 200, a lifting module 300, and a feeding module 400. The base 100 is movable. The support 200 is movably disposed above the base 100. The lifting module 300 is connected between the base 100 and the support 200 and can adjust the height of the support 200 relative to the base 100. The feeding module 400 includes a feeding plate 410 and a pushing member 420. The feeding plate 410 is disposed at the front end of the support 200 and can be horizontally connected with the support 200 during feeding. The thickness of the feeding plate 410 at least at the end away from the support 200 gradually increases from front to back. The pushing member 420 is disposed on the base 100 and can move back and forth to push the target material from the feeding plate 410 to the support 200.

[0044] The entire text is written in both the foreground and background directions. Figure 1 The markings in the diagram shall prevail. "Forward direction" is defined as the normal traveling direction of the material handling device 10, and "reverse direction" is its opposite.

[0045] The material handling device 10 can be applied to various production and distribution processes, such as in factory workshops, warehousing and logistics centers, port terminals, railway stations and airport cargo terminals.

[0046] When it is necessary to move the target material, first use the lifting module 300 to adjust the height of the support base 200 relative to the base 100 so that the support base 200 is roughly flush with the bottom surface of the target material. Then, connect the loading plate 410 horizontally to the support base 200 so that the front end of the loading plate 410 is facing the target material. Then, move the material handling device forward until the front end of the loading plate 410 is inserted under the target material. Then, push the pusher 420 backward to push the target material until the target material is pushed from the loading plate 410 onto the support base 200. Finally, use the material handling device 10 to move the target material to the target position.

[0047] As can be seen, this application, through the cooperation of the lifting module 300 and the feeding module 400, enables the entire material handling process to be completed without the need for manual handling of materials onto the material handling device or the use of forklifts or similar auxiliary equipment, thus ensuring the safety of passengers in the station and reducing the labor intensity of operators.

[0048] like Figure 3 In one embodiment, the feeding module 400 further includes a first power component 430 and a transmission assembly 440. The first power component 430 is connected to the base 100 via a first mounting bracket 450. The transmission assembly 440 includes a gear assembly 441 and a screw and nut assembly 442. The gear assembly 441 is driven between the output shaft of the first power component 430 and the screw and nut assembly 442, and the screw and nut assembly 442 is driven between the gear assembly 441 and the pusher 420, and can convert rotational motion into linear motion. When the output shaft of the first power component 430 rotates, the gear assembly 441 can transmit the rotational motion to the screw and nut assembly 442, and the screw and nut assembly 442 then converts the rotational motion into linear motion, enabling the pusher 420 to move back and forth.

[0049] The first power component 430 can be a motor. It should be noted that the number of feeding modules 400 can be set according to the weight of the target material. For targets with relatively small weights (e.g., less than 10 kg), one feeding module 400 can be used; for targets with large weights, two feeding modules 400 can be used, positioned on the left and right sides of the base 100. If the two feeding modules 400 are insufficient to push the target material, the first power component 430 can be directly configured as a cylinder, hydraulic cylinder, or other power cylinder. The pushing component 420 can be directly connected to the piston rod of the power cylinder. Compared to a motor, a power cylinder can apply a greater pushing force to the pushing component 420. (Note: The left and right directions are not explicitly stated in the original text.) Figure 1 The information shown shall prevail.

[0050] like Figure 3As shown, in one embodiment, the gear assembly 441 includes a driving gear 4411 and a driven gear 4412. The driving gear 4411 is mounted on the output shaft of the first power member 430, and the driven gear 4412 meshes with the driving gear 4411. When the output shaft of the first power member 430 rotates, the driving gear 4411 rotates, and the driven gear 4412 meshing with the driving gear 4411 also rotates, thereby transmitting the rotational motion to the screw and nut assembly 442.

[0051] like Figure 3 As shown, in one embodiment, the screw and nut assembly 442 includes a nut 4421, a screw 4422, and a guide rod 4423. The nut 4421 is rotatably mounted on a first mounting bracket 450 and has a driven gear 4412 fitted around its outer periphery. Both ends of the guide rod 4423 are connected to the screw 4422 via mounting plates 4424. The guide rod 4423 is slidably mounted on the first mounting bracket 450. The screw 4422 and the nut 4421 are slidably assembled. The pusher 420 is perpendicularly mounted on the front mounting plate 4424 and is rotatable. When the driven gear 4412 rotates, the nut 4421 connected to it also rotates on the first mounting bracket 450. The screw 4422 then moves back and forth under the guidance of the guide rod 4423, thereby driving the pusher 420 to move back and forth.

[0052] To facilitate the installation of the first power component 430 and the screw and nut assembly 442, the first mounting bracket 450 may include a first mounting part and a second mounting part that are perpendicular to each other. The first mounting part is arranged in the front-to-back direction, and the second mounting part is arranged in the left-to-right direction. The first power component 430 is located in the first mounting part, and the nut 4421 is located in the second mounting part. The second mounting part has a guide hole for the guide rod 4423 to pass through in the front and back.

[0053] The second mounting portion also has a through hole for mounting the nut 4421. To allow the nut 4421 to rotate together with the driven gear 4412, the nut 4421 needs to be in clearance fit with the through hole. However, this clearance fit would cause the nut 4421 to move back and forth during rotation. To address this, in one embodiment, the nut 4421 is provided with two limiting rings 4425 spaced apart along its axial direction. The two limiting rings 4425 are located on the front and rear sides of the second mounting portion of the first mounting bracket 450, respectively, to limit the back-and-forth movement distance of the nut 4421. The two limiting rings 4425 prevent the nut 4421 from moving back and forth during rotation.

[0054] It should be noted that before inserting the front end of the feeding plate 410 under the target material, the pushing member 420 needs to be rotated in a predetermined direction to the left or right side of the material handling device. When it is necessary to push the target material from the feeding plate 410 to the support base 200, the pushing member 420 is rotated in the opposite direction to the predetermined direction to position it directly in front of the target material, facilitating subsequent pushing of the target material. Based on this, the pushing member 420 is configured to be rotatable in this application. As an example, such as... Figure 4 As shown, the front mounting plate 4424 is provided with a screw cylinder 460, and one end of the pusher 420 is vertically protruding with a stud 421, which is threaded into the screw cylinder 460. Through the cooperation of the stud 421 and the screw cylinder 460, the pusher 420 can be installed on the front mounting plate 4424, and the pusher 420 can also be rotated.

[0055] To prevent the stud 421 from detaching from the screw barrel 460 due to excessive rotation of the pusher 420, such as Figure 4 As shown, the front end face of the screw barrel 460 is provided with an arc-shaped limiting plate 461, and the pushing member 420 can rotate in the gap between the head and tail of the limiting plate 461. The limiting plate 461 can limit the rotation amplitude of the pushing member 420 to prevent the pushing member 420 from rotating too much.

[0056] During installation, the stud 421 can be screwed into the screw barrel 460 first, and then the limiting plate 461 can be installed on the front end face of the screw barrel 460 by screwing, welding, bonding or other methods.

[0057] like Figure 2 As shown, in one embodiment, the lifting module 300 includes a second power component 310 and a linkage mechanism 320. The second power component 310 is disposed on the base 100 and is configured as a power cylinder. The linkage mechanism 320 is hinged between the piston rod of the second power component 310 and the support seat 200, and can drive the support seat 200 to move up and down when the piston rod of the second power component 310 extends or retracts. When the piston rod of the second power component 310 extends or retracts, the linkage mechanism 320 can be extended or retracted, thereby adjusting the up and down movement of the support seat 200. The second power component 310 is configured as a power cylinder, such as a pneumatic cylinder or a hydraulic cylinder. Compared to a motor, a power cylinder can provide a greater supporting force to the support seat 200 through the linkage mechanism 320, enabling the material handling device to bear a greater weight and improving the applicability of the material handling device 10.

[0058] In one embodiment, such as Figure 5As shown, the linkage mechanism 320 includes several cross units 321. Each cross unit 321 includes a first link 3211 and a second link 3212. The middle part of the first link 3211 and the middle part of the second link 3212 are hinged together. The upper end of the first link 3211 is located in front of the upper end of the second link 3212, and the lower end of the first link 3211 is located behind the lower end of the second link 3212. The upper end of the first link 3211 and the lower end of the second link 3212 are both hinged to the base 100. The lower end of the first link 3211 and the upper end of the second link 3212 are both slidably assembled with the base 100. The lower end of the second link 3212 is hinged to the piston rod of the second power member 310. When the piston rod of the second power member 310 retracts, the first connecting rod 3211 and the second connecting rod 3212 move closer to each other, thereby driving the support seat 200 to move upward; while when the piston rod of the second power member 310 extends, the first connecting rod 3211 and the second connecting rod 3212 move further apart, thereby driving the support seat 200 to move downward.

[0059] Of course, in some other embodiments, the upper end of the first connecting rod 3211 and the lower end of the second connecting rod 3212 are both slidably assembled with the base 100, the lower end of the first connecting rod 3211 and the upper end of the second connecting rod 3212 are both hinged to the base 100, and the lower end of the first connecting rod 3211 is hinged to the piston rod of the second power member 310.

[0060] Optionally, such as Figure 2 As shown, the lower end of the first connecting rod 3211 is provided with a first slider 3213, and the inner sidewall of the base 100 is provided with a first groove 110 along the front-rear direction, and the first slider 3213 is accommodated in the first groove 110; Figure 6 As shown, the upper end of the second connecting rod 3212 is provided with a second slider 3214, and the inner sidewall of the support base 200 is provided with a second sliding groove 210 along the front-back direction, and the second slider 3214 is accommodated in the second sliding groove 210.

[0061] To ensure the support strength of the support base 200, such as Figure 5 As shown, there are two cross units 321; the cross parts of the two cross units 321 share a first rotating shaft 322 for hinge connection; the lower ends of the first connecting rods 3211 of the two cross units 321 also share a second rotating shaft 323 for hinge connection with the base 100; the lower ends of the first connecting rods 3211 of the two cross units 321 are connected by a connecting rib 324; the piston rod of the second power member 310 is hinged to the connecting rib 324.

[0062] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in one embodiment, the material handling device 10 further includes a discharge mechanism 500, which includes a plurality of rotatable discharge wheels 510. The plurality of discharge wheels 510 are arranged at intervals in the front-back direction, and a portion of each discharge wheel 510 protrudes from the upper surface of the support base 200. When the target material is pushed onto the support base 200 from the loading plate 410, the target material can be transported to a suitable position by the rotation of the discharge wheels 510, eliminating the need for manual handling to adjust the storage position of the target material on the support base 200, thus reducing the labor intensity of the operators.

[0063] like Figure 6 As shown, the support base 200 has multiple openings 240, which are spaced apart in the front-to-back direction. Each opening 240 exposes a corresponding unloading wheel 510. The number of openings 240 is the same as the number of unloading wheels 510, and they correspond one-to-one. The number of unloading wheels 510 can be set to 2, 3, 4, or more. It should be noted that in order to clearly show the openings 240 on the support base 200, Figure 6 The foremost unloading wheel 510 is not shown.

[0064] like Figure 6 As shown, the lower side of the support base 200 is provided with multiple sets of connecting ear plates 220 in the front-to-back direction. Each set of connecting ear plates 220 includes two connecting ear plates 220. A mounting shaft 230 is connected between the two connecting ear plates 220. An opening 240 is provided between the corresponding two connecting ear plates 220 in the left-to-right direction. The unloading wheel 510 is rotatably mounted on the corresponding mounting shaft 230.

[0065] To prevent the target material from falling off the support 200 after being pushed to a suitable position on the support 200 due to the movement of the unloading wheel 510, such as... Figure 1 and Figure 2 As shown, the rear end of the feeding plate 410 is hinged to the front end of the support base 200. The material handling device 10 also includes a locking member 600, which is disposed on the base 100. When the feeding plate 410 rotates upward and becomes perpendicular to the support base 200, the locking member 600 can lock the feeding plate 410. The material handling device 10 also includes a baffle 700, which is movable back and forth on the support base 200 and located on the rear side of the feeding plate 410.

[0066] After the target material is pushed to a suitable position on the support base 200, the feeding plate 410 is rotated upwards. When the feeding plate 410 is perpendicular to the support base 200, the locking member 600 locks the feeding plate 410 to prevent it from rotating downwards due to gravity. The baffle 700 is then moved forward until it is against the rear side of the target material. The clamping of the feeding plate 410 and the baffle 700 prevents the target material from moving back and forth due to the rotation of the unloading wheel 510, thus preventing the target material from falling off the support base 200.

[0067] In one embodiment, such as Figure 1 , Figure 2 and Figure 6 As shown, the locking member 600 is inclined relative to the support base 200, and the rear end of the locking member 600 is fixedly connected to the support base 200. The front end of the locking member 600 can be screwed to the feed plate 410 via the first threaded member 610 when the feed plate 410 is perpendicular to the support base 200. The front end of the locking member 600 has a clear hole, and the feed plate 410 has a second threaded hole 411. When the feed plate 410 is perpendicular to the support base 200, the clear hole corresponds to the second threaded hole 411, and the first threaded member 610 can pass through the clear hole of the locking member 600 and be screwed into the second threaded hole 411 of the feed plate 410, thus locking the feed plate 410. When the feed plate 410 needs to be horizontally connected to the base 100, the first threaded member 610 simply needs to be unscrewed from the second threaded hole 411 of the feed plate 410.

[0068] The number of locking elements 600 can be set to two, with the two locking elements 600 located on the left and right sides of the support base 200.

[0069] like Figure 6 As shown, in one embodiment, both ends of the baffle 700 in the left and right directions are provided with downward protruding hook portions 710. The hook portions 710 are hooked onto the edge of the support base 200 and have first threaded holes. The material handling device 10 also includes two pressing members 800. The pressing members 800 are screws 4422 that can be movably inserted into the corresponding first threaded holes to press against or move away from the support base 200. When the baffle 700 moves forward and comes into contact with the rear side of the target material, the two pressing members 800 are screwed into the first threaded holes on the corresponding hook portions 710 until each pressing member 800 presses against the support base 200, thus fixing the baffle 700. When it is necessary to adjust the front and rear position of the baffle 700, the pressing members 800 are screwed out of the first threaded holes.

[0070] like Figure 1 and Figure 2As shown, in one embodiment, the material handling device 10 further includes a plurality of wheels 900, which are rotatably disposed on the bottom of the base 100. The material handling device 10 can move by means of the plurality of wheels 900, which simplifies the structure of the material handling device.

[0071] The number of 900 wheels can be set according to requirements, for example... Figure 1 and Figure 2 The base 100 shown in the figure has a wheel 900 at each of its four corners.

[0072] Optionally, such as Figure 1 As shown, the traveling wheel 900 may include a wheel frame 910 and a wheel body 920. The wheel body 920 is rotatably mounted on the wheel frame 910, and the wheel frame 910 is rotatably mounted on the bottom of the base 100. The traveling wheel 900 with this structure can rotate in all directions, which facilitates the material handling device to handle materials.

[0073] like Figure 1 and Figure 2 As shown, in one embodiment, the material handling device 10 further includes a pusher 1000, which is disposed on the base 100 and located behind the support 200. The pusher 1000 facilitates the operator to push the material handling device.

[0074] The push handle 1000 can be roughly inverted "U" shape, with the upper end of the push handle 1000 tilted backward. This makes it easier for the operator to hold the push handle 1000.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
