Description

Technical Field

[0001] This utility model relates to the field of loading and unloading platforms, specifically to a forklift push-pull loading and unloading platform. Background Technology

[0002] In automated material handling and transportation, materials are loaded into transport vehicles from the supply location and unloaded from the transport vehicles to the destination, requiring basic handling and loading functions to meet user requirements. Loading and unloading are crucial links in the logistics process, and with the rapid development of modern cargo loading and transportation technologies, more and more users need to achieve rapid loading and transfer of materials.

[0003] For large palletized materials, current technology typically involves two or more forklifts working together to simultaneously pick up the material. One forklift aligns one end of the material with the container and feeds it in, while the other forklifts push the material into the container from the other end. This method has the following drawbacks: 1. If the material is large and there is no room for it to move within the container, the forklifts cannot rise after picking it up, thus preventing the material from being fed into or out of the container; 2. It requires the use of multiple forklifts working together, resulting in low efficiency and making it difficult to implement each step of the loading and unloading process.

[0004] The purpose of this utility model research is to design a forklift-type push-pull loading and unloading platform to address the problems existing in the prior art. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a forklift push-pull loading and unloading platform, which can effectively solve at least one of the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A forklift-type push-pull loading and unloading platform includes:

[0008] The installation platform is driven by a lifting mechanism and a lateral shifting mechanism;

[0009] Roller conveyor chains are installed on the left and right sides of the installation platform;

[0010] A fork assembly, comprising a first drive chain, a mounting rail, and fork components, wherein the mounting rail is located at the middle position of the mounting platform, and the fork components are connected to the mounting rail; the first drive chain drives the fork components to move back and forth along the mounting rail to extend or retract from the mounting platform.

[0011] The lever assembly includes a second drive chain and a lever. The second drive chain is disposed between the first drive chain and the fork assembly. The lever is disposed between the second drive chains. The lever is driven by the second drive chain to flip up and then move horizontally in the front-back direction above the second drive chain.

[0012] Furthermore, the lifting mechanism includes a lifting outrigger, which is equipped with a lifting drive cylinder; the side-shifting mechanism includes a side-shifting outrigger, which is equipped with a lateral shifting drive cylinder.

[0013] Furthermore, the fork assembly includes a translation push plate, and a translation push plate receiving groove is provided at the middle position of the mounting platform, with the translation push plate laid in the translation push plate receiving groove.

[0014] Furthermore, the fork assembly includes a push seat, which is fixedly connected to the front end of the translational push plate. During the process of pushing the material into the container, the front end of the push seat abuts against the rear end of the material.

[0015] Furthermore, the push base is provided with a hook receiving groove, a connecting rod is hinged to the middle position of the hook receiving groove, and a hook is hinged to the end of the connecting rod. After the connecting rod swings forward, the hook extends out of the front end of the push base, and after the connecting rod swings backward, the hook is stored in the hook receiving groove.

[0016] Furthermore, the translational push plate is lower than the roller conveyor chain, and the connecting rod includes a first branch rod and a second branch rod. The first branch rod and the second branch rod are hinged together. The first branch rod is hinged to the middle position of the hook receiving groove. A stop block is provided on the front side of the hinge end of the first branch rod and the hook receiving groove. After the first branch rod swings forward at a certain angle, it is blocked by the stop block. The height of the first branch rod after being blocked by the stop block is higher than the stop block.

[0017] Furthermore, the lever is driven by the second transmission chain to fold down and be stored on the side of the second transmission chain.

[0018] Furthermore, it includes a first feed sensor and a second feed sensor, the first feed sensor being located near the rear end of the mounting platform, and the second feed sensor being located near the front end of the mounting platform.

[0019] Therefore, this utility model provides the following effects and / or advantages:

[0020] This application utilizes a roller conveyor chain to transport materials into containers, and the speed of material entry into the container is further accelerated by a lever assembly. Simultaneously, the fork assembly extends from the mounting platform to further propel the material into the container after it has entered. This application enables continuous and efficient loading and unloading of materials, significantly reducing material handling time, reducing manpower and material resources, and improving work efficiency. It also solves the problems of forklifts being unable to avoid pallet frames during pallet handling, or the high workload and low efficiency of manual forklift handling. Therefore, this proposed development project should have significant market demand and a broad market prospect.

[0021] This application is equipped with a hook, which can be used to pull the material out of the container by hooking it to the rear end of the material.

[0022] The hook of this application is connected by a first branch rod and a second branch rod that are hinged in sequence, and a stop block is provided accordingly. This ensures that when the hook is hooked at the rear end of the material, the hook can always be hooked at the rear end of the material during the raising or lowering of the installation platform, without affecting the lifting and lowering of the installation platform. This improves the adaptability of the loading and unloading platform to materials of different shapes.

[0023] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0024] It should be understood that the above summary and the following detailed description of the present invention are exemplary and explanatory, and are intended to provide further explanation of the present invention as claimed. Attached Figure Description

[0031] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0032] Example 1

[0033] refer to Figure 1-6 A forklift-type push-pull loading and unloading platform, comprising:

[0034] The mounting platform 1 is driven by the lifting mechanism 11 and the lateral shifting mechanism 12;

[0035] Further, the lifting mechanism 11 includes lifting legs, each equipped with a lifting drive cylinder; the side-shifting mechanism 12 includes a side-shifting leg 121, each equipped with a lateral movement drive cylinder 122. In this embodiment, the side-shifting leg 121 forms a drawer-like structure, allowing for lateral movement in the left-right direction. The lateral movement drive cylinder 122 drives the side-shifting leg 121 to move left and right. The specific structures of the lifting mechanism 11 and the side-shifting mechanism 12 are prior art; refer to the existing application with publication number CN114789881A, entitled "A Loading System and Control Method Thereof." The installation platform 1 is driven by the lifting mechanism 11 and the side-shifting mechanism 12, enabling alignment with different container trucks, ensuring that the installation platform 1 is at the same height and aligned with the container truck's container.

[0036] Roller conveyor chains 2 are disposed on the left and right sides of the mounting platform 1;

[0037] The roller conveyor chain 2 in this embodiment includes a roller chain, which is driven by a motor to achieve power transmission. When material is placed on the roller conveyor chain 2, the motor drives the roller chain to roll, thereby conveying the material forward and allowing it to enter the container.

[0038] The fork assembly 3 includes a first drive chain 31, a mounting rail 32, and fork members 33. The mounting rail 32 is located at the middle position of the mounting platform 1, and the fork members 33 are connected to the mounting rail 32. The first drive chain 31 drives the fork members 33 to move back and forth along the mounting rail 32 to extend or retract from the mounting platform 1.

[0039] After the material is fed into the container, there is still space at the end of the container near the front of the vehicle. At this time, it is necessary to push the material further into the container. In this embodiment, the fork assembly 3 can extend. When the material is fed into the container through the roller conveyor chain 2, the rear end of the material is flush with the rear end of the container. The material is completely pushed into the container by extending the fork assembly 3.

[0040] The lever assembly 4 includes a second transmission chain 41 and a lever 42. The second transmission chain 41 is disposed between the first transmission chain 31 and the fork member 33. The lever 42 is disposed between the second transmission chains 41. The lever 42 is driven by the second transmission chain 41 to flip up and then move horizontally in the front-back direction above the second transmission chain 41.

[0041] When the material is heavy, the material is conveyed slowly on the roller conveyor chain 2. Therefore, by working the lever 42 of the lever assembly 4, it flips up and moves horizontally in the front-back direction above the second transmission chain 41, thereby pushing the material forward at the rear end and speeding up the speed at which the material enters the container.

[0042] Furthermore, the fork component 33 includes a translation push plate 331, and a translation push plate receiving groove 13 is provided at the middle position of the mounting platform 1, and the translation push plate 331 is laid in the translation push plate receiving groove 13.

[0043] Furthermore, the fork assembly 33 includes a push seat 332, which is fixedly connected to the front end of the translation push plate 331. During the process of pushing the material into the container, the front end of the push seat 332 abuts against the rear end of the material.

[0044] Furthermore, the push seat 332 is provided with a hook receiving groove 3321, a connecting rod 5 is hinged to the middle position of the hook receiving groove 3321, and a hook 6 is hinged to the end of the connecting rod 5. After the connecting rod 5 swings forward, the hook 6 extends out of the front end of the push seat 332. After the connecting rod 5 swings backward, the hook 6 is stored in the hook receiving groove 3321.

[0045] When materials need to be removed from the container, they must be pulled out of the container. In this embodiment, a hook 6 is hinged to the push base 332. The hook 6 can swing forward or backward through the hinged structure, thereby being stored in the hook receiving slot 3321 or extending to the front end of the push base 332. When pulling materials out of the container, the hook 6 is swung forward, so that it can hook onto the rear end of the material or a hook or other structure on the material. Then, the forks 33 retract, and the material is removed from the container.

[0046] Furthermore, the translational push plate 331 is lower than the roller conveyor chain 2. The connecting rod 5 includes a first branch rod 51 and a second branch rod 52, which are hinged together. The first branch rod 51 is hinged to the middle position of the hook receiving groove 3321. A stop block 7 is provided on the front side of the hinge end of the first branch rod 51 and the hook receiving groove 3321. After the first branch rod 51 swings forward at a certain angle, it is blocked by the stop block 7. The height of the first branch rod 51 after being blocked by the stop block 7 is higher than the stop block 7.

[0047] In this embodiment, if the bottom of the material is not flush, that is, if the material has two sides higher than the middle position, the translation push plate 331 is lower than the roller conveyor chain 2, which can better adapt to the shape of the material. Thus, when the material is placed on the roller conveyor chain 2, the roller conveyor chain 2 is supported on the left and right sides of the material, and the fork assembly is supported in the middle of the material.

[0048] In this case, after the material is fed into the container via the roller conveyor chain 2, the lifting mechanism 11 rises to a certain height, thereby raising the mounting platform 1 and the fork assembly 3 together, so that the fork 33 is slightly higher than the bottom surface of the container. At this time, when the fork 33 is pushed forward, it can abut against the rear end of the material. Conversely, when the material retreats to the rear end of the container, the lifting mechanism 11 also needs to descend to a certain height so that the material can return to the roller conveyor chain 2. Therefore, in this embodiment, the first branch rod 51 swings forward at a certain angle and is blocked by the stop block 7, so that the top end of the first branch rod 51 is higher than the stop block 7. At this time, one end of the second branch rod 52 is higher than the stop block 7. During the descent of the lifting mechanism 11, the top end of the first branch rod 51 descends synchronously. With the structure of the top end of the second branch rod 52 hinged to the top end of the first branch rod 51, the hook 6 can be kept flush with the hook position of the material.

[0049] Furthermore, the lever 42 is driven by the second transmission chain 41 to fold down and be stored on the side of the second transmission chain 41.

[0050] This structure allows for the concealment of the lever 42, preventing it from obstructing the feeding of goods into the roller conveyor chain 2.

[0051] Furthermore, it includes a first feed sensor (not shown) and a second feed sensor (not shown), the first feed sensor being located near the rear end of the mounting platform 1, and the second feed sensor being located near the front end of the mounting platform 1.

[0052] The first feed sensor can detect whether the material has completely entered the rear end of the roller conveyor chain 2, and thus activate the lever assembly 4 to push the material at the corresponding moment. The second feed sensor can determine whether the material has detached from the front end of the roller conveyor chain 2, and thus retract the lever assembly 4.
