The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0028] Example:

[0029] like Figure 1 As shown, a freight elevator is provided in this embodiment, including a guide mechanism, the guide mechanism including a translation mechanism 1, a lifting mechanism 2 arranged on the translation mechanism 1 and a pulling mechanism 3 arranged on the lifting mechanism 2, the translation mechanism 1 drives the lifting mechanism 2 to translate, the lifting mechanism 2 drives the pulling mechanism 3 to lift and lower, and the pulling mechanism 3 includes a retractable fork 31.

[0030] In this embodiment, a cargo elevator for transporting goods is provided, and the cargo elevator includes a guide mechanism for moving a fork 31, so as to effectively perform the cargo transport task. The guide mechanism includes a translation mechanism 1, a lifting mechanism 2 arranged on the translation mechanism 1, and a pulling mechanism 3 arranged on the lifting mechanism 2, and the fork 31 for transporting goods is arranged on the pulling mechanism 3. The translation mechanism 1 drives the lifting mechanism 2 and the pulling mechanism 3 (fork 31) on the lifting mechanism 2 to translate along the X axis, and the lifting mechanism 2 drives the pulling mechanism 3 and the fork 31 to rise and fall along the Z axis. In addition, the fork 31 can also be extended and retracted along the Y axis, so the guide mechanism enables the fork 31 to have the ability to move along the X axis, the Y axis and the Z axis. The guide mechanism enables the fork 31 to move freely in a three-dimensional space through the coordinated work of the translation mechanism 1, the lifting mechanism 2 and the pulling mechanism 3, so that the cargo elevator can accurately and quickly locate the goods in the warehouse or shelf system, and perform the tasks of transporting, stacking and picking up goods, thereby improving production efficiency. The freight elevator in the present application has high flexibility and accuracy, and is suitable for fast and accurate handling of goods in automated warehouses or logistics centers. Specifically, the freight elevator in the present application can be a lifting device such as a stacker.

[0031] like Figure 2 As shown, the translation mechanism 1 includes a translation driving assembly, a first beam 11 and a second beam 12 arranged opposite to the first beam 11 , and the translation driving assembly drives the lifting mechanism 2 to translate along the first beam 11 and the second beam 12 .

[0032] In this embodiment, the translation drive assembly is used to drive the entire lifting mechanism 2 and the pulling mechanism 3 and the fork 31 connected thereto to move horizontally along a predetermined track or path. The first crossbeam 11 is arranged at the upper part of the freight elevator as a top beam, providing a stable support structure for the lifting mechanism 2. Therefore, the first crossbeam 11 needs to have good rigidity and load-bearing capacity. Specifically, the first crossbeam 11 can be welded from steel plates and steel sections. The second crossbeam 12 is arranged at the lower part of the freight elevator. It is arranged opposite to the first crossbeam 11 as a bottom beam, and mainly plays a role in guiding the lifting mechanism 2. Through the cooperation of the first crossbeam 11 and the second crossbeam 12, the stable movement of the lifting mechanism 2 in the horizontal direction can be ensured. In other embodiments, the first crossbeam 11 can also be arranged below the second crossbeam 12 as a bottom beam, which is not limited here.

[0033] The translation driving assembly includes a first slide rail 111 arranged on the first crossbeam 11 , a first pulley 13 rolling along the first slide rail 111 , and a first motor 15 connected to the first pulley 13 ; the first pulley 13 is rotatably arranged on the lifting mechanism 2 .

[0034] In this embodiment, the first slide rail 111 is arranged on the first beam 11 and provides a rolling track for the first pulley 13, ensuring the stability and accuracy of the first pulley 13 during the translation process. The first pulley 13 is rotatably arranged on the lifting mechanism 2, that is, when the first pulley 13 rolls on the first slide rail 111, the pulley can drive the lifting mechanism 2 to translate along the first beam 11. The first motor 15 serves as a power source for the translation drive assembly, and drives the first pulley 13 to realize the movement of the lifting mechanism 2 in the X-axis direction.

[0035] like Figure 3 As shown, the translation drive assembly includes a second slide rail 121 arranged on the second crossbeam 12, a second pulley 14 rolling along the second slide rail 121, and a second motor 16 connected to the second pulley 14; the lifting mechanism 2 includes a pair of guide wheels 17 clamped and matched with the slide rail.

[0036] In this embodiment, the second slide rail 121 is arranged on the second crossbeam 12 and provides a rolling track for the second pulley 14, ensuring the stability and accuracy of the second pulley 14 during the translation process. In addition, the first slide rail 111 and the second slide rail 121 are arranged in parallel, and the second slide rail 121 and the second pulley 14 are mainly used to guide the lifting mechanism 2, so that the lifting mechanism 2 moves along the path of the second slide rail 121 and the first slide rail 111. The second motor 16 is connected to the second pulley 14 to provide power for it. The paired guide wheels 17 are installed on the lifting mechanism 2, which are clamped and matched with the second slide rail 121 to ensure the stability and guidance of the lifting mechanism 2 during the translation process. The paired design makes the lifting mechanism 2 more stable when moving, reducing shaking and errors.

[0037] The first slide rail 111 and the second slide rail 121 are both configured as rack structures, and the first pulley 13 and the second pulley 14 are both configured as gears.

[0038] In this embodiment, the first slide rail 111 and the second slide rail 121 have a series of equidistantly arranged teeth, which mesh with the teeth of the first pulley 13 and the second pulley 14 to provide accurate rolling and positioning tracks for the first pulley 13 (gear) and the second pulley 14 (gear). The rack and pinion transmission system has high transmission efficiency and stability, reduces shaking and errors during translation, makes the freight elevator more stable and accurate during translation, and improves the efficiency and accuracy of cargo handling.

[0039] like Figure 5 and Figure 6As shown, the translation drive assembly includes a load-bearing member 18 connecting the lifting mechanism 2 and the first beam 11, and the load-bearing member 18 includes a load-bearing wheel 181 matched with the first beam 11 and a rotating shaft 182 rotatably connected to the lifting mechanism 2. In this embodiment, the load-bearing member 18 stably connects the lifting mechanism 2 to the first beam 11 and allows the lifting mechanism 2 to smoothly translate along the first beam 11. Specifically, the load-bearing member 18 includes a load-bearing wheel 181 and a rotating shaft 182 rotatably arranged on the lifting mechanism 2. The load-bearing wheel 181 can roll along the track (which may be a rack structure or other forms) of the first beam 11 to provide stable support and smooth translation. According to the weight and size of the lifting mechanism 2, the load-bearing wheel 181 may be distributed on the first beam 11 in multiple forms to ensure uniform force and smooth operation. The rotating shaft 182 is a component connecting the load-bearing wheel 181 and the lifting mechanism 2. The rotating shaft 182 allows the load-bearing wheel 181 to rotate freely around its axis, thereby supporting the translation of the lifting mechanism 2 on the first crossbeam 11. The rotating shaft 182 is usually made of wear-resistant, impact-resistant and high-load-bearing materials to ensure its long-term stable operation. The load-bearing member 18 is made of wear-resistant and impact-resistant materials, which can withstand a large load and meet the needs of the freight elevator when carrying heavy objects.

[0040] like Figure 4 As shown, the lifting mechanism 2 includes a lifting drive assembly and at least one column 21 , and the lifting drive assembly drives the pulling mechanism 3 to lift and lower along the column 21 .

[0041] In this embodiment, the lifting mechanism 2 is used to move the pulling mechanism 3 in the Z-axis direction to grab or place the goods, and the lifting drive assembly can provide power to drive the pulling mechanism 3 to perform lifting and lowering movements along the column 21. The column 21, as the main supporting structure of the lifting mechanism 2, can bear the weight of the lifting mechanism 2 and the pulling mechanism 3 as well as the weight of the goods. According to the design and application requirements of the freight elevator, the lifting mechanism 2 may include one or more columns 21. The design of multiple columns 21 can improve the stability and load-bearing capacity of the lifting mechanism 2.

[0042] The lifting drive assembly includes a third slide rail 22 arranged on the column 21, a third pulley 23 rolling along the third slide rail 22, and a third motor 24 connected to the third pulley 23; the lifting drive assembly also includes a guide plate 25 that can slide along the column 21, and the third pulley 23 is rotatably connected to the guide plate 25.

[0043] In this embodiment, the third slide rail 22 is disposed on the column 21 and arranged along the height direction of the column 21. The third slide rail 22 provides a rolling track for the third pulley 23, ensuring the stability and accuracy of the third pulley 23 and the pulling mechanism 3 during the lifting process. The third pulley 23 rolls along the third slide rail 22 to achieve the movement of the pulling mechanism 3 and the fork 31 along the Z axis. The lifting drive assembly also includes a guide plate 25, which is clamped on the column 21 by a plurality of pulleys to achieve movement along the column 21, and the pulling mechanism 3 is fixed to the guide plate 25, and the guide plate 25 is connected to the third pulley 23 by a rotatable connecting shaft, so that the pulling mechanism 3 follows the guide plate 25 and the third pulley 23 to move up and down along the column 21.

[0044] The pulling mechanism 3 includes a support plate 32 connected to the lifting mechanism 2 and a telescopic plate 33 fixed to the fork 31 . The telescopic plate 33 is slidably disposed on the support plate 32 .

[0045] In this embodiment, the support plate 32 provides a stable support platform for the telescopic plate 33, ensuring that the telescopic plate 33 can remain stable during the telescopic process. The support plate 32 is connected to the lifting mechanism 2, and the support plate 32 can move in the Z-axis direction through the driving of the lifting mechanism 2. When it is necessary to grab the goods, the telescopic plate 33 slides on the support plate 32, so that the fork 31 moves toward the goods and grabs the goods. When it is necessary to place the goods, the telescopic plate 33 slides again, so that the fork 31 moves the goods to the specified position and puts it down. There are many ways for the telescopic plate 33 to cooperate with the support plate 32, which will not be repeated here.

[0046] This embodiment also provides a warehousing system, which includes a freight elevator and a shelf. The shelf is provided with at least one compartment for storing goods. The freight elevator is used to take and place goods in the compartment. The freight elevator includes the aforementioned freight elevator.

[0047] In the present embodiment, the storage system is mainly composed of a freight elevator and a shelf. The shelf is equipped with a plurality of compartments for storing goods. The freight elevator is responsible for moving the position of the fork 31 to perform the picking and placing operations of the goods. When the storage system receives a pick-up or placing instruction, the control system controls the translation drive assembly and the lifting drive assembly of the freight elevator to move according to the goods number and position information specified in the instruction, so that the freight elevator moves to the specified shelf position. Then, the control system controls the pulling mechanism 3 to perform the picking and placing operations of the goods, taking the goods out of the compartment or putting them into the compartment. Finally, the control system controls the freight elevator to return to its original position or move to the next working position. In the present embodiment, the freight elevator is fixed on the ground. In other embodiments, tracks that cooperate with the freight elevator can also be laid to change the position of the freight elevator.

Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
