Description

Technical Field

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

[0002] In the logistics industry, loading and unloading are both labor-intensive and cost-intensive. There are many ways to load goods. Some are to place them on pallets and transfer them directly with the pallets. Some are to transfer them directly by adsorbing cargo boxes. Some are even still transported manually from the entrance or side of the carriage.

[0003] The traditional unloading method is to move the grabbing structure to the corresponding position of the goods, grab the goods onto the straight conveyor belt and transport them to the outside of the car. However, the grabbing mechanism moves up and down, which prolongs the unloading cycle. Therefore, some existing technologies set the position of the conveyor belt to a high position or a low position, thereby shortening the distance between the grabbing structure and the conveyor belt and improving the transportation efficiency. However, since the height of the container may be different each time it is unloaded, the height of the conveyor belt needs to be additionally adjusted each time the transfer platform is laid out, and the conveyor belt must also be gradually adjusted as the height of the goods decreases. Not only does the overall workload increase, but it also greatly prolongs the unloading time, resulting in prolonged unloading time for batches of goods.

[0004] Therefore, this case aims to provide a container cargo transfer platform, in which the entire conveying platform is installed on a platform vehicle, which can move with the platform vehicle, and the conveying platform can be directly adjusted to an upper or lower height on the platform vehicle, and can span the bottom and top of the container body, and can adapt to containers of most heights.

[0013] As a further improvement, a side rail frame is movably installed on the upper end of the transmission frame, and the side rail frame includes a plurality of connecting rods hinged on the outside of the transmission frame. A side rail is hingedly installed on the top of the connecting rod. The side of the side rail close to the pickup end is hinged to the mounting frame, and the side of the side rail away from the pickup end is hinged to the outside of the transmission frame.

[0014] As a further improvement, a short track is provided on the outer side of the transmission frame, and a long track is provided on the inner side of the front frame and the rear frame, and the connecting member cooperates with the short track and the long track respectively.

[0015] As a further improvement, a driven machine platform is hinged at the end of the transmission frame, a fixed machine platform is installed at the tail end of the driven machine platform, and the fixed machine platform is connected to the movable frame through a fixing member.

[0016] The beneficial effects of the present invention are: Existing cargo needs to change its height according to the height of the cargo during the unloading stage in order to achieve the effect of fast loading and unloading. However, the heights of different trucks are different, and the heights of the cargo are different. If real-time adjustments are made every time the cargo arrives at the site, a longer unloading time is required. Therefore, the cargo transfer platform provided by the present invention can allow the platform to directly enter the interior of the truck through a mobile chassis, and an adjustable transmission component is also provided on the mobile chassis, which can allow the transmission frame to change its height through a power system and a driven structure, so that the transmission frame can reach the highest point or the lowest point of the truck, so that the platform can not only adapt to vehicles with different cargo heights, but also can gradually lower its own height as the cargo height decreases, ensuring that there is a better receiving point throughout the unloading cycle, thereby avoiding unloading errors and improving the unloading effect.

[0017] The driven structure is the key to the mobility of the transmission frame, among which the key to the direction change of the transmission frame lies in the front driven end. When the first driving structure in the front driven end rotates, the second revolver is linked to the first transmission shaft through the first revolver, so that the front end belt body rotates, and then drives the connecting piece to move up and down, so as to realize the change of the position of the connecting piece, and then the position of the transmission frame connected to the connecting piece is changed, so as to achieve real-time adjustment of the transmission height.

[0018] In order to fully ensure the moving accuracy of the belt body and thus ensure the moving progress of the connecting piece, the first and second revolvers of the present invention are not simply gear belt transmissions, but through the coordination between matching gears, tension gears, and adjustment gears, the front end of the belt body can move in a taut posture when moving, thereby achieving the most accurate moving accuracy, and then allowing the transmission frame to reach a more accurate position, so that the goods can be received by the transmission frame after being adsorbed.

[0019] Different trucks have different heights, and some trucks are smaller in height. Therefore, if the height of the platform is set too high, it is easy to cause small trucks to be unable to enter. If the platform is set too low, the transmission frame after displacement still cannot reach the highest height of the large truck. Therefore, the present invention sets a rear driven end at the position of the rear chassis, and the position of the belt body at the rear end can be changed by the rear driven end, thereby driving the height of the connecting part at the rear end, and then the transmission frame whose height has been changed can be raised again, so that the height setting of the platform can be changed, and then the height of the entire transmission frame can be raised to a position flush with the highest height of the large truck by secondary lifting.

[0020] Although the transmission rack can achieve the effect of transmitting goods, it does not have the effect of limiting and guiding the goods, and the goods are easy to slide or fall from the lateral position. Therefore, the present invention also arranges a side rail frame at the position of the transmission rack, and the side rail frame is used to limit the lateral direction of the transmission rack. In order to adapt to the position change of the transmission rack, the side rail frame is not a fixed setting, but is connected to the transmission rack through a movable connecting rod, so that the height of the side rail frame can also change during the rising and falling process of the transmission rack, and it is not easy to collide with other structures.

[0021] During the up and down movement of the transmission frame, it all depends on the cooperation between the connecting piece and the belt body. The connecting piece is only connected to the belt body and is less guided during its movement. It is easy to deviate from the original position when it is reset. Therefore, the present invention can guide the movement of the connecting piece in two directions by setting a short track and a long track, so that it can return to the original position along the original trajectory after moving, so that each movement can achieve a very precise effect.

DETAILED DESCRIPTION

[0031] In order to make the embodiments of the present invention, all belong to the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0032] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as referring to the purpose, technical solutions and advantages of the methods. To be more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0033] Reference Figure 1 to Figure 7 As shown, a container cargo transfer platform comprises: a mobile chassis, a plurality of walking wheels 101 are arranged at the bottom of the mobile chassis, and a power system 102 is arranged on the inner side of the mobile chassis; a movable frame movably arranged on the top of the mobile chassis, the movable frame comprises a movable frame 201 which moves relative to the mobile chassis, and a driven structure 202 connected to the power system 102 is arranged on the movable frame 201; an adjustable height adjustment transmission component 3 comprises a transmission frame 301 connected to the mounting frame 10, a plurality of transmission surfaces for transmitting cargo to the rear end are arranged on the inner side of the transmission frame 301, a plurality of connecting members 302 are movably installed on the outer side of the transmission frame 301, and a plurality of the connecting members 302 are locked on a plurality of belt bodies 303 on the driven structure 202, and when the driven structure 202 drives the belt body 303 to move up and down, the belt body 303 drives the connecting member 302 and the transmission frame 301 connected to the connecting member 302 to lift or descend.

[0034] The platform is moved into the compartment of the truck via the running wheels 101, and the driven structure 202 is driven by the power system 102 to move, so that the belt body 303 drives the connecting piece 302 and the transmission frame 301 to reach a specified height to start unloading.

[0035] Existing cargo needs to change its height according to the height of the cargo during the unloading stage in order to achieve the effect of fast loading and unloading. However, the heights of different trucks are different, and the heights of the cargo are different. If real-time adjustments are made every time the cargo arrives at the site, a longer unloading time is required. Therefore, the cargo transfer platform provided by the present invention allows the platform to directly enter the interior of the truck through a mobile chassis, and an adjustable transmission component 3 is also provided on the mobile chassis, which allows the transmission frame 301 to change its own height through a power system 102 and a driven structure 202, so that the transmission frame 301 can reach the highest point or the lowest point of the truck, so that the platform can not only adapt to vehicles with different cargo heights, but also gradually lower its own height as the cargo height decreases, ensuring that there is a better receiving point throughout the unloading cycle, thereby avoiding unloading errors and improving the unloading effect.

[0036] During the process of raising or lowering the transmission frame 301, the transmission frame 301 cannot be adjusted in situ, but needs to undergo slight deformation. Therefore, the movable frame in this embodiment includes a front frame 103 and a rear frame 104. The height of the rear frame 104 is higher than the front frame 103. Guide rails 105 are provided on both sides of the top of the front frame 103 and the rear frame 104. The movable frame slides with the guide rails 105. A vacuum pump is provided in the front frame 103. The movable frame is movable, and its movement is derived from the cooperation with the guide rails 105 on the movable frame, so that the position of the movable frame itself can be changed, so that the transmission frame 301 installed on the movable frame is not prone to mechanical interference when the height changes. The vacuum pump is a structure that provides power for the adsorption end. Due to its large size, it is also installed in the front frame 103 with a lower height and larger space.

[0037] Since the vacuum pump and other power structures need to be installed in the entire mobile chassis, it is difficult to set up a four-wheel drive structure inside the platform. The activities of the entire movable frame and the power system 102 are also arranged 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 an excessively high vehicle bottom that increases the overall height of the platform, thereby avoiding the inability to enter some small vehicles.

[0038] The driven structure 202 is distributed on the entire movable frame, but since it is difficult for the front and rear ends to form a linkage, the front and rear ends are driven separately. Therefore, the power system 102 of this embodiment includes a first driving structure 1021 arranged on the front base frame 103 and a second driving structure 1022 arranged on the rear base frame 104. The first driving structure 1021 and the second driving structure 1022 are both used to drive the driven structure 202. A linear driving member 1023 is also installed on the rear base frame 104. The output end of the linear driving member 1023 is connected to the movable frame 201. When the linear driving member 1023 is pushed out, the movable frame 201 moves toward the end of picking up the goods. The power system 102 has multiple driving structures, and the linear driving member 1023 for driving the movable frame itself is also arranged on the movable base frame, so that the movement of the movable frame does not conflict with the movable base frame.

[0039] The entire movable frame 201 is an integrated structure, but in order 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 arranged on the rear chassis 104. The front frame 2011 and the rear frame 2012 are connected by a plurality of connecting arms. The lower ends of the front frame 2011 and the rear frame 2012 are both provided with a slide 2013 that cooperates with the guide rail 105. The output end of the linear drive 1023 is connected to one of the connecting arms. When the linear drive 1023 is pushed out, the front frame 2011 and the rear frame 2012 move forward at the same time. In order to facilitate their movement, the front frame 2011 and the rear frame 2012 are still integrated. The linear drive 1023 only drives one end to drive the other end to move, so that the position of the entire movable frame 201 can be changed.

[0040] The driven structure 202 is the key to the mobility of the transmission frame 301. The driven structure 202 includes a front driven end 2021 and a rear driven end 2022 arranged on the slide 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 rotary device 20212 through a belt. The first rotary device 20212 is connected to the second rotary device 20214 through a first transmission shaft 20213. The first rotary device 20212 and the second rotary device 20214 are both connected to the front end belt body 303. The top of the front end belt body 303 is wound After passing through the first fixed wheel 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 direction-changing transmission frame 301 lies in the front driven end 2021. When the first driving structure 1021 in the front driven end 2021 rotates, the second rotating device 20214 is linked via the first transmission shaft 20213 through the first rotating device 20212, so that the front end The belt body 303 rotates, and then drives the connecting member 302 to move up and down, thereby realizing the change of the position of the connecting member 302, and then the position of the transmission frame 301 connected to the connecting member 302 is changed, and the transmission height is adjusted in real time.

[0041] In order to fully ensure the movement accuracy of the belt body 303 and thus ensure the movement progress of the connecting member 302, the first circular motion device 20212 and the second circular motion device 20214 of this embodiment have the same structure and size. The first circular motion device 20212 includes a circular gear 202121 connected to the belt, and the circular gear 202121 is connected to a docking seat 202122 on the side close to the first transmission shaft 20213, and the circular gear 202121 is connected to a matching gear 202123 on the side away from the first transmission shaft 20213. A tension gear 202124 is installed on the front frame 2011. The lower end of the belt body 303 is connected to To an adjusting gear 202125, the matching gear 202123, the tension gear 202124, and the adjusting gear 202125 are all connected by belts. The first rotary unit 20212 and the second rotary unit 20214 are not simply driven by gear belts, but through the matching gear 202123, the tension gear 202124, and the adjusting gear 202125, the front end belt body 303 can move in a taut posture when moving, thereby achieving the most accurate movement accuracy, and then allowing the transmission frame 301 to reach a more accurate position, so that the goods can be caught by the transmission frame 301 after being adsorbed.

[0042] Different trucks have different heights, and some trucks are smaller in height. Therefore, if the height of the platform is set too high, it is easy to cause small trucks to be unable to enter. If the platform is set too low, the transmission frame 301 after displacement still cannot reach the highest height of the large truck. Therefore, the rear driven end 2022 of this embodiment includes a rear connecting portion 20221 connected to the second driving structure 1022, and the rear connecting portion 20221 is connected to the third rotary device 20222 through a belt. The third rotary device 20222 is connected to the fourth rotary device 20224 through a second transmission shaft 20223. The third rotary device 20222 and the fourth rotary device 20224 are both connected The belt body 303 at the rear end is connected to the belt body 303, the top of the belt body 303 at the rear end is wound around the second fixed wheel 20225, and the connecting piece 302 at the rear end is locked on the belt body 303 and moves up and down with the belt body 303. A rear driven end 2022 is set at the position of the rear bottom frame 104. The position of the belt body 303 at the rear end can be changed by the rear driven end 2022, thereby driving the height of the connecting piece 302 at the rear end, and then the height of the transmission frame 301 that has been changed can be raised again, so that the height setting of the platform can be explained, and then the height of the entire transmission frame 301 can be raised to a position that is flush with the highest height of the large truck by secondary lifting.

[0043] Although the transmission frame 301 can achieve the effect of transmitting goods, it does not have the effect of limiting and guiding the goods, and the goods are easy to slide or fall from the lateral position. Therefore, a side fence frame 304 is movably installed on the upper end of the transmission frame 301 of the embodiment, and the side fence frame 304 includes a plurality of connecting rods 3041 hinged on the outside of the transmission frame 301. A side fence 3042 is hingedly installed on the top of the connecting rod 3041. The side of the side fence 3042 close to the pickup end is hinged to the mounting frame 10. The side of 042 away from the pickup end is hinged to the outer side of the transmission frame 301, and a side rail frame 304 is set at the position of the transmission frame 301. The side rail frame 304 is used to limit the side of the transmission frame 301. In order to adapt to the position change of the transmission frame 301, the side rail frame 304 is not a fixed setting, but is connected to the transmission frame 301 through a movable connecting rod 3041, so that the height of the side rail frame 304 can also change during the rising and falling process of the transmission frame 301, and it is not easy to collide with other structures.

[0044] During the up and down movement of the transmission frame 301, it all depends on the cooperation between the connecting piece 302 and the belt body 303. The connecting piece 302 is only connected to the belt body 303, and is less guided during its movement. It is easy to deviate from the original position when it is reset. Therefore, a short track 3011 is provided on the outer side of the transmission frame 301 of this embodiment, and a long track 2024 is provided on the inner side of the front frame 2011 and the rear frame 2012. The connecting piece 302 cooperates with the short track 3011 and the long track 2024 respectively. The movement of the connecting piece 302 can be guided in two directions, so that it can return to the original position along the original trajectory after its movement, so that each movement can achieve a very precise effect.

[0045] The length of the transmission frame 301 is not enough to connect the goods with the processing equipment of the next stage. Therefore, a slave platform 305 is hinged at the end of the transmission frame 301 of this embodiment, and a fixed platform 306 is installed at the tail end of the slave platform 305. The fixed platform 306 is connected to the movable frame through a fixing part 307. Among them, the slave platform 305 does not have a separate power structure and will be linked with the transmission frame 301 through a hinge relationship, and the fixed platform 306 is fixed to the movable frame through fixing parts 307 such as a fixed frame and a diagonal rod, and will not change its position.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
