Description

Technical Field

[0001] This utility model relates to the field of container technology, and in particular to a container transfer device. Background Technology

[0002] Containers are the core of modern logistics. They are standardized steel containers that ensure cargo safety through their robustness, airtightness, and reusability. Their core advantage lies in their uniform specifications, allowing them to be efficiently transferred between ships, trains, and trucks like building blocks, forming a seamless multimodal transport system. This greatly improves the efficiency of global cargo loading, unloading, and turnover, significantly reduces transportation costs and time, and has spurred the development of specialized vessels and port equipment to support them.

[0003] In the production and transfer of containers, due to their large weight and size, cylinders are often used as a power source to push them to the next workstation. However, existing pushing methods have obvious limitations: on the one hand, due to the large mass and strong inertia of the container, the cylinder piston rod is prone to radial vibration during extension, which not only affects the stability of the pushing process, but may also damage the cylinder structure in the long run; on the other hand, limited by the cylinder's own stroke, its effective pushing distance is limited, making it difficult to meet the needs of long-distance transfer, and often requiring the use of other auxiliary mechanisms, resulting in system complexity and reduced efficiency. Utility Model Content

[0004] In order to effectively improve the transshipment rate of containers, this application provides a container transshipment device.

[0005] This application provides a container transshipment device, which adopts the following technical solution: A container transfer device includes a mounting base plate, a container body placed on the mounting base plate, two sets of parallel slide rails disposed on the mounting base plate, pulleys disposed at the bottom of the four bottom corners of the container body and slidingly engaged with the slide rails, and a transfer mechanism for pushing the container body to slide on the slide rails. The bottom of the four bottom corners of the container body is provided with abutment protrusions for the transfer mechanism to abut. The transfer mechanism includes a first cylinder assembly and a second cylinder assembly. After being pushed by the transfer mechanism, the container body has a first transfer station and a second transfer station.

[0006] By adopting the above technical solution, the container body is first placed on two sets of parallel slide rails on the mounting base plate with the help of bottom pulleys, and is in the first transfer station. Then, the first cylinder assembly located on both sides of the slide rail end is activated, and its first push seat abuts against the abutment protrusion at the rear bottom corner of the container body, providing initial thrust to make the container body move along the slide rail. When the container body enters the middle of the stroke, the second cylinder assembly takes over, and its second push seat moves forward under the guidance of the guide slide rail. The end push arm abuts against the abutment protrusion at the rear bottom corner of the container body, thereby providing a smooth and precise subsequent thrust, and finally pushing the container body to the second transfer station.

[0007] Optionally, the first cylinder assembly includes a first cylinder disposed on the mounting base plate and located on both sides of the slide rail end, and a first push seat disposed on the piston rod end of the first cylinder, the first push seat abutting against the abutting protrusion.

[0008] By adopting the above technical solution, the first cylinders symmetrically arranged on both sides of the slide rail end allow for simultaneous application of pushing force from both sides of the container body, ensuring uniform distribution of pushing force and preventing the container body from tilting or jamming during movement. Simultaneously, the first pushing seat directly abuts against the abutment protrusion, reducing impact and wear, and improving the accuracy and stability of the pushing action.

[0009] Optionally, the second cylinder assembly includes a second cylinder disposed on the mounting base plate and located on both sides of the slide rail, and a second push seat disposed at the end of the piston rod of the second cylinder; the mounting base plate is provided with a guide slide rail for the second push seat to slide.

[0010] By adopting the above technical solution, the guide rail guides the second pusher to move along a predetermined path, ensuring accurate pushing direction, preventing the second pusher from deviating or shaking, and improving the consistency and controllability of pushing.

[0011] Optionally, the second push seat includes a slider that cooperates with the guide rail, a push arm that is rotatably hinged to the top of the slider, a limiting block disposed on the top of the slider and located at the rear end of the push arm, and a return spring connected at one end to the push arm and at the other end to the top of the slider, wherein the push arm abuts against the abutting protrusion.

[0012] By adopting the above technical solution, the specific structure of the second pusher is disclosed. When the container body is pushed to the middle of its stroke by the first cylinder, the push arm abuts against the abutment protrusion. The limiting block at its rear end provides a stop, preventing the push arm from rotating backward while pushing the container body, thereby ensuring effective transmission of thrust and ultimately pushing it smoothly to the second transfer station. Furthermore, the rotatably hinged push arm can rotate forward to make way for obstacles such as pulleys at the bottom of the container body, avoiding interference. After making way, the push arm can automatically return to its initial position by the elastic force of the return spring, ready for the next pushing operation.

[0013] Optionally, the slider has limiting protrusions on both sides, and the guide rail has limiting grooves that cooperate with the limiting protrusions.

[0014] By adopting the above technical solution, the slider is provided with a limiting protrusion, which cooperates with the limiting groove of the guide rail to prevent the slider from swaying laterally during movement.

[0015] Optionally, one end of the guide rail is provided with a mounting seat for mounting the second cylinder, and the mounting seat and the second cylinder are connected by bolts; the mounting seat is also provided with a mounting hole for the piston rod of the second cylinder to pass through.

[0016] By adopting the above technical solution, a mounting base is provided for the installation of the second cylinder, and the mounting base and the second cylinder are connected by bolts, which facilitates the installation and disassembly of the second cylinder and makes it convenient to repair and replace the second cylinder.

[0017] Optionally, it also includes a translation mechanism disposed on both sides of the slide rail. The translation mechanism includes two sets of parallel translation tracks disposed on the mounting base plate and a conveyor belt disposed within the translation tracks. The translation tracks are disposed perpendicular to the slide rail, and one end of the track extends through the slide rail and connects with the translation track on the opposite side.

[0018] By adopting the above technical solution, the translation mechanism is arranged vertically with the slide rail, which gives the container body the ability to transfer in both the horizontal and vertical directions, breaking through the limitation of single linear transfer, expanding the operating range, and adapting to more complex logistics scenarios.

[0019] Optionally, at each intersection of the slide rail and the translation track, an opening groove is provided on the slide rail; the opening grooves of the slide rail are arranged symmetrically with respect to the translation track.

[0020] By adopting the above technical solution, symmetrical opening slots are specially designed at the intersection of the slide rail and the translation rail, providing an unobstructed passage for the conveyor belt and ensuring the smooth transition of the container body between the slide rail and the translation rail, thereby improving the transfer efficiency.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. A container transfer device, wherein the container body is placed on a slide rail at a first transfer station via bottom pulleys; a first cylinder at the end of the slide rail is activated, and a first pusher abuts against the rear abutment protrusion of the container body, providing initial thrust to make it slide; when it reaches the middle of the stroke, a second cylinder takes over, and its second pusher advances along the guide slide rail, with its end pusher arm abutting against the front abutment protrusion of the container body, applying a smooth and precise subsequent thrust, and finally pushing the container body to the second transfer station; 2. The limiting protrusion of the slider cooperates with the limiting groove of the guide rail to prevent the slider from swaying laterally during movement; 3. By arranging the translation mechanism perpendicular to the slide rail, the container body is given the ability to be transported in both the horizontal and vertical directions, breaking through the limitation of single linear transport and expanding the operating range.

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0030] This application discloses a container transfer device. (Refer to...) Figure 1 and Figure 2 A container transfer device includes a mounting base plate 1, a container body 2 placed on the mounting base plate 1, two sets of parallel slide rails 3 mounted on the mounting base plate 1, pulleys 4 located at the bottom of the four bottom corners of the container body 2 and slidingly engaged with the slide rails 3, a transfer mechanism 5 for pushing the container body 2 to slide on the slide rails 3, and a translation mechanism 6 located on both sides of the slide rails 3. The bottom of the four bottom corners of the container body 2 is provided with abutment protrusions 21 for the transfer mechanism to abut against, and the container body 2, after being pushed by the transfer mechanism 5, has a first transfer station and a second transfer station.

[0031] Reference Figure 1 The transfer mechanism 5 includes a first cylinder assembly 51 and a second cylinder assembly 52. ​​Through the cooperation of the first cylinder assembly 51 and the second cylinder assembly 52, the container body 2 can be transported from the first transfer station to the second transfer station.

[0032] Reference Figure 1 and Figure 3 The first cylinder assembly 51 includes a first cylinder 511 and a first push seat 512. The first cylinder 511 is disposed on the mounting base plate 1 and located on both sides of the end of the slide rail 3, and is fixed to the mounting base plate 1 by bolts. The first push seat 512 is installed at the end of the piston rod of the first cylinder 511, and the first push seat 512 is a block structure. When the container body 2 is in the initial position, when the piston rod of the first cylinder 511 extends, the first push seat 512 abuts against the abutment protrusion 21 at the rear bottom corner of the container body 2, providing initial thrust to make the container body 2 slide from the first transfer station to the middle of the stroke.

[0033] Reference Figure 4 and Figure 5 Each second cylinder assembly 52 includes a second cylinder 521 and a second pusher seat 522. The second cylinder 521 is disposed on the mounting base 1 and located on both sides of the slide rail 3, and is fixed to the mounting seat 112 on the mounting base 1 by bolts. The mounting base 1 is provided with a guide slide rail 11 for the second pusher seat 522 to slide. One end of the guide slide rail 11 is provided with a mounting seat 112 for mounting the second cylinder 521, and the mounting seat 112 and the second cylinder 521 are connected by fastening bolts 113; the mounting also has a mounting hole 1121 for the piston rod of the second cylinder 521 to pass through.

[0034] Reference Figure 3 and Figure 5The second pusher seat 522 includes a slider 5221 that cooperates with the guide rail 11, a push arm 5222 that is rotatably hinged to the top of the slider 5221, a limiting block 5223 located on the top of the slider 5221 and at the rear end of the push arm 5222, and a return spring 5224 connected at one end to the push arm 5222 and at the other end to the top of the slider 5221. The push arm 5222 abuts against the abutment protrusion 21. When the container body 2 enters the middle of its stroke, the piston rod of the second cylinder 521 extends, driving the second pusher seat 522 forward. Its push arm 5222 then abuts against the abutment protrusion 21 at the rear corner of the container body 2, and the slider 5221 slides along the guide rail 11, thereby providing a smooth and precise subsequent thrust to the container and finally pushing it to the second transfer station.

[0035] Reference Figure 4 and Figure 5 The slider 5221 has limiting protrusions 52211 on both sides, and the guide rail 11 has limiting grooves 111 that cooperate with the limiting protrusions 52211. Through the cooperation of the limiting protrusions 52211 and the limiting grooves 111, the slider 5221 can be prevented from lateral swaying during movement. Reference Figure 4 The translation mechanism 6 includes two sets of parallel translation tracks 61 mounted on the mounting base plate 1 and a conveyor belt 62 disposed within the translation tracks 61. The translation tracks 61 are perpendicular to the slide rails 3, with one end extending through the slide rails 3 and connecting with the opposite translation track 61. If lateral transport is required, the conveyor belt 62 of the translation mechanism 6, driven by a motor, causes the container body 2 to slide on the translation slide rails 3, achieving movement perpendicular to the slide rails 3 and completing automated multi-station, multi-directional transport.

[0036] Reference Figure 4 and Figure 6 At each intersection of the slide rail 3 and the translation track 61, an opening groove 31 is provided on the slide rail 3; the opening grooves 31 of the slide rail 3 are arranged symmetrically with respect to the translation track 61. By specially providing symmetrical opening grooves 31 at the intersection of the slide rail 3 and the translation track 61, an unobstructed passage is provided for the conveyor belt 62.

[0037] The implementation principle of a container transfer device according to an embodiment of this application is as follows: When the container transfer device is in operation, the container body 2 is placed on the slide rail 3 at the first transfer station via the bottom pulley 4; the first cylinder 511 at the end of the slide rail 3 is activated, and the first push seat 512 abuts against the rear corner of the container body 2 against the protrusion 21, providing initial thrust to make it slide; when it reaches the middle of the stroke, the second cylinder 521 takes over, and its second push seat 522 moves forward along the guide slide rail 11, with the end push arm 5222 abutting against the rear corner of the container body 2 against the protrusion 21, applying a stable and precise subsequent thrust, and finally pushing the container body 2 to the second transfer station; wherein, if lateral transfer is required, the conveyor belt 62 of the translation mechanism 6 can be activated, driving the container body 2 to slide on the translation slide rail 3, realizing movement perpendicular to the direction of the slide rail 3, thereby completing the automated flow of multiple stations and multiple directions.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
