Description

Technical Field

[0001] The present invention relates to a cargo transfer device, in particular to a container cargo transfer platform. Background Art

[0002] In the logistics industry, loading and unloading are both labor-intensive and the most costly parts. There are various ways of loading goods. Some are to place them on pallets and directly transfer them together with the pallets, some are to directly transfer them by adsorbing the cargo boxes, and even some still stay in the manual handling method, handling from the carriage inlet or the side opening of the carriage.

[0003] The traditional unloading method is to move the grasping structure to the corresponding position of the goods, grasp the goods onto a flat conveyor belt and convey them to the outside of the carriage. However, the grasping mechanism moves up and down, which prolongs the unloading cycle. Therefore, in some prior arts, the position of the conveyor belt is set at a high position or a low position, thereby shortening the distance between the grasping structure and the conveyor belt and improving the conveying efficiency. However, since the height of the container may be different each time when unloading, it is necessary to additionally adjust the height of the conveyor belt every time when arranging the transfer platform, and the conveyor belt also needs to be gradually adjusted as the height of the goods decreases. Not only does the overall workload increase, but also the unloading time is greatly prolonged, resulting in an extended unloading time for batches of goods.

[0004] Therefore, the present case aims to provide a container cargo transfer platform, which installs the entire conveying platform on a platform vehicle, can move along with the platform vehicle, and the conveying platform can directly adjust the height of the upper or lower position on the platform vehicle, can span the bottom and the top of the box body, and can adapt to containers of most heights. Summary of the Invention

[0005] The present invention provides a container cargo transfer platform, which can effectively solve the above problems.

[0006] The present invention is implemented as follows:

[0007] A container cargo transfer platform, comprising:

[0008] A moving chassis, wherein a plurality of walking wheels are arranged at the bottom of the moving chassis, and a power system is arranged inside the moving chassis;

[0009] An active frame movably arranged on the top of the moving chassis, the active frame includes an active frame that moves relative to the moving chassis, and a driven structure connected to the power system is arranged on the active frame;

[0010] An adjustable-height transfer assembly, comprising a transfer machine frame connected to a mounting frame. Inside the transfer machine frame, there are several transfer surfaces for transferring goods to the rear end. Several connecting pieces are movably installed on the outside of the transfer machine frame, and the several connecting pieces are locked onto several belts of a driven structure. When the driven structure drives the belts to move up and down, the belts drive the connecting pieces and the transfer machine frame connected to the connecting pieces to lift or lower.

[0011] As a further improvement, the movable chassis comprises a front chassis and a rear chassis. The height of the rear chassis is higher than that of the front chassis. Guide rails are provided on both sides of the tops of the front chassis and the rear chassis. The movable machine frame is slidably matched with the guide rails. A vacuum pump is provided in the front chassis.

[0012] As a further improvement, the power system comprises a first driving structure provided on the front chassis and a second driving structure provided on the rear chassis. Both the first driving structure and the second driving structure are used to drive the driven structure. A linear driving member is also installed on the rear chassis, and the output end of the linear driving member is connected to the movable frame. When the linear driving member extends, the movable frame moves towards the end for picking up goods.

[0013] As a further improvement, the movable frame comprises a front frame located at the position of the front chassis, and a rear frame is provided on the rear chassis. The front frame and the rear frame are connected by several connecting arms. Sliding seats for cooperating with the guide rails are provided at the lower ends of the front frame and the rear frame. The output end of the linear driving member is connected to one of the connecting arms. When the linear driving member extends, the front frame and the rear frame move forward simultaneously.

[0014] As a further improvement, the driven structure comprises a front driven end and a rear driven end provided on the sliding seat. The front driven end comprises a front connecting part connected to the first driving structure. The front connecting part is connected to a first turnover device through a belt. The first turnover device is connected to a second turnover device through a first transmission shaft. Both the first turnover device and the second turnover device are connected to the belt at the front end. The top of the belt at the front end is wound around a first fixed pulley member, and the connecting piece at the front end is locked onto the belt and moves up and down with the belt.

[0015] As a further improvement, the first turnover device and the second turnover device have the same structure and size. The first turnover device comprises a turnover gear connected to the belt. One docking seat is connected to the side of the turnover gear close to the first transmission shaft, and a mating gear is connected to the side of the turnover gear away from the first transmission shaft. A tension gear is installed on the front frame. The lower end of the belt is connected to an adjusting gear. The mating gear, the tension gear, and the adjusting gear are all connected by belts.

[0016] As a further improvement, the rear driven end includes a rear connecting part connected to the second driving structure. The rear connecting part is connected to a third turnover device through a belt. The third turnover device is connected to a fourth turnover device through a second transmission shaft. Both the third turnover device and the fourth turnover device are connected to the belt body at the rear end. The top of the belt body at the rear end is wound around a second fixed wheel member, and the connecting member at the rear end is locked on the belt body and moves up and down with the belt body.

[0017] As a further improvement, a side railing frame is movably installed at the upper end of the transmission rack. The side railing frame includes a plurality of connecting rods hinged to the outside of the transmission rack. A side railing is hingedly installed at the top of the connecting rod. One side of the side railing close to the goods pickup end is hinged to the mounting frame, and the side of the side railing far from the goods pickup end is hinged to the outside of the transmission rack.

[0018] As a further improvement, a short track is arranged on the outside of the transmission rack, and long tracks are arranged on the inner sides of the front frame and the rear frame. The connecting member cooperates with the short track and the long track respectively.

[0019] As a further improvement, a driven machine platform is hinged to the end of the transmission rack. A fixed machine platform is installed at the tail end of the driven machine platform. The fixed machine platform is connected to the movable rack through a fixing member.

[0020] The beneficial effects of the present invention are as follows:

[0021] For existing goods, their heights need to be changed according to the height of the goods during the unloading stage in order to achieve the effect of rapid loading and unloading. However, the heights of different trucks and goods are different. If real-time adjustment is carried out every time after the goods arrive, a relatively long unloading time is required. Therefore, the goods transfer platform provided by the present invention can enable the platform to directly enter the interior of the truck through the movable chassis, and an adjustable transmission assembly is also arranged on the movable chassis, which can enable the transmission rack to change its own height through the power system and the driven structure, so that the transmission rack can reach the highest or lowest point of the truck, and further enable the platform to not only adapt to vehicles with different goods heights, but also gradually lower its own height as the height of the goods decreases, ensuring that there is a good goods receiving point throughout the unloading cycle, thus avoiding unloading mistakes and improving the unloading effect at the same time.

[0022] The driven structure is the key to the movement of the transmission rack. Among them, the key to the adjustable direction of the transmission rack lies in the front driven end. When the first driving structure in the front driven end rotates, it drives the second turnover device through the first turnover device and the first transmission shaft, making the belt body at the front end rotate, and then driving the connecting member to move up and down, thereby realizing the change of the position of the connecting member, and further changing the position of the transmission rack connected to the connecting member, and achieving the adjustment of the transmission height in real time.

[0023] To fully ensure the movement accuracy of the belt body and thus the movement progress of the connecting piece, the first turnover device and the second turnover device of the present invention do not simply use a gear-belt drive. Instead, through the cooperation among the mating gear, the tension gear, and the adjusting gear, the belt body at the front end can move in a taut state during movement, thereby achieving the most accurate movement accuracy. Furthermore, the transmission rack can reach a relatively accurate position, so that the goods can be caught by the transmission rack after being adsorbed.

[0024] The heights of different trucks are different. The heights of some trucks are relatively small. Therefore, if the height of the platform is set too high, it is easy for small trucks to be unable to enter. If the platform is set too low, the transmission rack after displacement still cannot reach the highest height of large trucks. Therefore, the present invention sets a rear driven end at the position of the rear chassis. By means of the rear driven end, the position of the belt body at the rear end can be changed, thereby driving the height of the connecting piece at the rear end. Furthermore, the transmission rack whose height has already been changed can be lifted again, so that the height of the platform can be set relatively low. Then, through secondary lifting, the height of the entire transmission rack can be raised to a position flush with the highest height of large trucks.

[0025] Although the transmission rack can achieve the effect of transporting goods, it does not have the effect of limiting and guiding the goods, and the goods are likely to slip or fall from the side position. Therefore, the present invention also sets a side railing at the position of the transmission rack to limit the side of the transmission rack. In order to adapt to the position change of the transmission rack, the side railing is not fixedly arranged, but is connected to the transmission rack through movable connecting rods. Thus, during the rising and falling process of the transmission rack, the height of the side railing can also change, and it is not easy to collide with other structures.

[0026] During the up and down movement of the transmission rack, it all depends on the cooperation between the connecting piece and the belt body. The connecting piece is only related to the belt body, and it is less guided during its movement. Then, when it is reset, it is likely to deviate from the original position. Therefore, the present invention sets a short track and a long track to guide the movement of the connecting piece in two directions. Thus, after its movement, it can return to the original position along the original track, so that each movement can achieve a very precise effect. Brief Description of the Drawings

Detailed implementation manners

[0037] To implement the present invention, all of them fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0038] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined. In the description of the present invention, for the purpose of making the purpose, technical solution and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of the present invention.

[0039] Refer to Figures 1 to 7 As shown, a container cargo transfer platform includes: a mobile chassis, several traveling wheels 101 are provided at the bottom of the mobile chassis, and a power system 102 is provided inside the mobile chassis; a movable frame is movably arranged on the top of the mobile chassis, the movable frame includes a movable frame 201 that moves relative to the mobile chassis, and a driven structure 202 connected to the power system 102 is provided on the movable frame 201; an adjustable-height adjustment transmission assembly 3, including a transmission chassis 301 connected to a mounting frame 10, several transmission surfaces for transmitting goods to the rear end are provided inside the transmission chassis 301, several connecting members 302 are movably installed outside the transmission chassis 301, and the several connecting members 302 are locked on several belts 303 of the driven structure 202. When the driven structure 202 drives the belts 303 to move up and down, the belts 303 drive the connecting members 302 and the transmission chassis 301 connected to the connecting members 302 to lift or lower.

[0040] Move the platform into the carriage of the truck through the traveling wheels 101, and then drive the driven structure 202 to act through the power system 102, so that the belts 303 drive the connecting members 302 and the transmission chassis 301 to reach the specified height to start unloading.

[0041] Existing goods need to change their own height according to the height of the goods during the unloading stage in order to achieve the effect of rapid loading and unloading. However, the heights of different trucks and the goods are different. If the adjustment is made in real time after the goods arrive each time, a relatively long unloading time is required. Therefore, the goods transfer platform provided by the present invention enables the platform to directly enter the interior of the truck through the mobile chassis. Moreover, an adjustment transmission assembly 3 is provided on the mobile chassis, which can enable the transmission rack 301 to change its own height through the power system 102 and the driven structure 202, so that the transmission rack 301 can reach the highest or lowest point of the truck, and further enable the platform to not only adapt to vehicles with different goods heights, but also gradually lower its own height as the height of the goods decreases, ensuring that there is a good goods receiving point throughout the unloading cycle, thereby avoiding unloading errors and improving the unloading effect at the same time.

[0042] During the upward or downward adjustment of the transmission rack 301, the transmission rack 301 cannot be adjusted in place, but needs to undergo some deformation. Therefore, in the mobile chassis of this embodiment, it includes a front chassis 103 and a rear chassis 104. The height of the rear chassis 104 is higher than that of the front chassis 103. Guide rails 105 are provided on both sides of the tops of the front chassis 103 and the rear chassis 104. The movable rack is slidably matched with the guide rails 105. A vacuum pump is provided in the front chassis 103. The movable rack is movable, and its movement is due to the cooperation with the guide rails 105 on the mobile chassis, so as to be able to realize the change of the position of the movable rack itself, and further make it difficult for the transmission rack 301 installed on the movable rack to have mechanical interference when the height changes. The vacuum pump is a structure that provides power for the adsorption end. Since its volume is relatively large, it is also installed in the front chassis 103 with a lower height and a larger space.

[0043] Since a vacuum pump and other power structures need to be installed inside the entire mobile chassis, it is difficult to set a four-wheel drive structure inside the platform. The movement of the entire movable rack and the power system 102 are also set in sections. In this embodiment, the inner side of the mobile chassis is divided into a front chassis 103 and a rear chassis 104, and most of the power structures are integrated into the front chassis 103, so that the entire structure can be made lower, avoiding the overall height of the platform being increased due to too high a vehicle bottom, and further avoiding being unable to enter some small vehicles.

[0044] The driven structure 202 is distributed across the entire movable frame. However, since it is difficult to form a linkage at the front and rear ends, the front and rear ends are driven separately. Therefore, the power system 102 of this embodiment includes a first driving structure 1021 disposed on the front chassis 103 and a second driving structure 1022 disposed on the rear chassis 104. Both the first driving structure 1021 and the second driving structure 1022 are used to drive the driven structure 202. A linear driving member 1023 is also installed on the rear chassis 104, and the output end of the linear driving member 1023 is connected to the movable frame 201. When the linear driving member 1023 extends, the movable frame 201 moves towards the end for picking up goods. The power system 102 has multiple driving structures, and the linear driving member 1023 for driving the movable frame itself is also disposed on the movable chassis, so that the movement of the movable frame does not conflict with the movable chassis.

[0045] The entire movable frame 201 has an integral structure. However, to adapt to the shape of the movable chassis, it is also divided into two parts. Specifically, the movable frame 201 includes a front frame 2011 located at the position of the front chassis 103, and a rear frame 2012 is disposed on the rear chassis 104. The front frame 2011 and the rear frame 2012 are connected by a plurality of connecting arms. Sliding seats 2013 that cooperate with the guide rails 105 are disposed at the lower ends of the front frame 2011 and the rear frame 2012. The output end of the linear driving member 1023 is connected to one of the connecting arms. When the linear driving member 1023 extends, the front frame 2011 and the rear frame 2012 move forward simultaneously. To facilitate their movement, the front frame 2011 and the rear frame 2012 are integrally arranged. The linear driving member 1023 only needs to drive one end to drive the other end to move, so that the position of the entire movable frame 201 can change.

[0046] The driven structure 202 is the key to the movability of the transmission frame 301. The driven structure 202 includes a front driven end 2021 and a rear driven end 2022 disposed on the sliding seat 2013. The front driven end 2021 includes a front connecting portion 20211 connected to the first driving structure 1021. The front connecting portion 20211 is connected to the first turnover device 20212 through a belt. The first turnover device 20212 is connected to the second turnover device 20214 through the first transmission shaft 20213. Both the first turnover device 20212 and the second turnover device 20214 are connected to the belt body 303 at the front end. The top of the belt body 303 at the front end is wound around the first fixed wheel member 20215. The connecting member 302 at the front end is locked on the belt body 303 and moves up and down with the belt body 303. Among them, the key to the adjustable direction of the transmission frame 301 lies in the front driven end 2021. When the first driving structure 1021 in the front driven end 2021 rotates, it drives the second turnover device 20214 through the first turnover device 20212 via the first transmission shaft 20213, causing the belt body 303 at the front end to rotate, thereby driving the connecting member 302 to move up and down, realizing the change in the position of the connecting member 302, and further changing the position of the transmission frame 301 connected to the connecting member 302, and adjusting the transmission height in real time.

[0047] In order to fully ensure the movement accuracy of the belt body 303 and further ensure the movement progress of the connecting member 302, the first turnover device 20212 and the second turnover device 20214 in this embodiment have the same structure and size. The first turnover device 20212 includes a turnover gear 202121 connected to the belt. One side of the turnover gear 202121 close to the first transmission shaft 20213 is connected with a pair of connecting seats 202122. The side of the turnover gear 202121 away from the first transmission shaft 20213 is connected with a mating gear 202123. A tension gear 202124 is installed on the front frame 2011. The lower end of the belt body 303 is connected to an adjusting gear 202125. The mating gear 202123, the tension gear 202124, and the adjusting gear 202125 are all connected by belts. The first turnover device 20212 and the second turnover device 20214 are not simply gear-belt transmissions, but through the cooperation among the mating gear 202123, the tension gear 202124, and the adjusting gear 202125, enabling the belt body 303 at the front end to move in a taut state when moving, so as to achieve the most accurate movement accuracy, and further enabling the transmission frame 301 to reach a relatively accurate position, so that the goods can be caught by the transmission frame 301 after being adsorbed.

[0048] The heights of different trucks vary, and some trucks have a smaller height. Therefore, if the height of the platform is set too high, it is likely that small trucks cannot enter. If the platform is set too low, the transmission rack 301 after displacement still cannot reach the maximum height of large trucks. Thus, in this embodiment, the rear driven end 2022 includes a rear connection part 20221 connected to the second drive structure 1022. The rear connection part 20221 is connected to the third turnover device 20222 through a belt. The third turnover device 20222 is connected to the fourth turnover device 20224 through the second transmission shaft 20223. Both the third turnover device 20222 and the fourth turnover device 20224 are connected to the belt body 303 at the rear end. The top of the belt body 303 at the rear end is wound around the second fixed wheel member 20225. The connecting member 302 at the rear end is locked on the belt body 303 and moves up and down with the belt body 303. The rear driven end 2022 is provided at the position of the rear chassis 104. The position of the belt body 303 at the rear end can be changed through the rear driven end 2022, thereby driving the height of the connecting member 302 at the rear end. Furthermore, the transmission rack 301, whose height has already been changed, can be lifted again, so that the height of the platform can be set lower, and then the height of the entire transmission rack 301 can be raised to a position flush with the maximum height of large trucks by means of secondary lifting.

[0049] Although the transmission rack 301 can achieve the effect of transporting goods, it does not have the effect of limiting and guiding the goods, and the goods are likely to slide or fall from the side position. Thus, in the embodiment, a side railing 304 is movably installed at the upper end of the transmission rack 301. The side railing 304 includes several connecting rods 3041 hinged to the outside of the transmission rack 301. The top of the connecting rod 3041 is hinged with a side railing 3042. One side of the side railing 3042 close to the goods pickup end is hinged to the mounting frame 10, and the other side of the side railing 3042 away from the goods pickup end is hinged to the outside of the transmission rack 301. The side railing 304 is provided at the position of the transmission rack 301 to limit the side of the transmission rack 301. In order to adapt to the position change of the transmission rack 301, the side railing 304 is not fixedly arranged, but is connected to the transmission rack 301 through the movable connecting rods 3041. Thus, the height of the side railing 304 can also change during the rising and falling process of the transmission rack 301, and it is not easy to collide with other structures.

[0050] During the up and down movement of the transmission rack 301, it entirely relies on the cooperation between the connecting member 302 and the belt body 303. The connecting member 302 is only connected to the belt body 303 and receives less guidance during its movement. Therefore, it is prone to deviation from its original position during reset. Thus, a short track 3011 is provided on the outer side of the transmission rack 301 in this embodiment. Long tracks 2024 are provided on the inner sides of the front frame 2011 and the rear frame 2012. The connecting member 302 cooperates with the short track 3011 and the long track 2024 respectively. By providing the short track 3011 and the long track 2024, the movement of the connecting member 302 can be guided in two directions, so that it can return to its original position along the original trajectory after movement, thereby achieving a very precise effect for each movement.

[0051] The length of the transmission rack 301 is not sufficient to connect the goods with the processing equipment in the next stage. Therefore, a driven machine table 305 is hinged at the end of the transmission rack 301 in this embodiment. A fixed machine table 306 is installed at the tail end of the driven machine table 305. The fixed machine table 306 is connected to the movable rack through a fixing member 307. Among them, the driven machine table 305 has no separate power structure and will be linked with the transmission rack 301 through the hinge relationship. The fixed machine table 306 is fixedly connected to the movable rack through fixing members 307 such as a fixed frame and an inclined rod and will not change its position.

[0052] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
