Description

Technical Field

[0001] This utility model relates to the field of warehousing technology, specifically to an airbag-type cargo platform stabilization mechanism, a cargo platform, a handling device, and a warehousing system. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Current warehousing systems typically employ hollow cargo handling devices, including a mother car that connects to a loading platform via a lifting belt mechanism. The mother car travels along the rack tracks, while the lifting belt mechanism drives the loading platform to move up and down. Through the movement of the mother car and the lifting of the loading platform, the platform reaches the target storage location. The loading platform is equipped with a picking and placing mechanism to transport goods from the loading platform to the target storage location or to transfer goods from the target storage location to the loading platform. To ensure stability during picking and placing, the loading platform is equipped with a stabilizing mechanism. During operation, this stabilizing mechanism engages with the rack, ensuring platform stability. This stabilizing mechanism typically includes a push-drive component connected to a push rod, which engages with the rack. The push-drive component uses an electric telescopic rod or a rack and pinion transmission mechanism. However, this stabilizing mechanism suffers from two main drawbacks: firstly, it generates rigid collisions with the rack, making it prone to damage and resulting in high maintenance costs; secondly, it is unsuitable for extreme environments such as high or low temperatures or dusty environments, requiring stringent environmental conditions. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an airbag-type cargo platform stabilization mechanism, cargo platform, handling device and storage system, which avoids the problems of rigid collision and has strong environmental adaptability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, an embodiment of the present invention provides an airbag-type cargo platform stabilization mechanism, including a housing for fixing to the cargo platform, an airbag inside the housing, the airbag being connected to an inflation / deflation pump via an air pipe, one end of the airbag being connected to the housing, and the other end being connected to one end of a push rod, the push rod extending out of the housing and being slidably connected to the housing, a fixing head being provided at the end of the push rod extending out of the housing, and an elastic element being provided between the push rod and the housing.

[0006] Optionally, the elastic element is a spring, which is sleeved on the outer periphery of the top rod. One end of the spring is connected to the top rod, and the other end is fixedly connected to the housing.

[0007] Optionally, a baffle is provided on the top rod, and the baffle is connected to one end of the spring.

[0008] Optionally, the airbag is composed of multiple airbag sections distributed along the direction of movement of the push rod, with adjacent airbag sections interconnected.

[0009] Optionally, the fixing head is an electromagnetic suction head, which is connected to a power supply for mounting on the loading platform.

[0010] Secondly, embodiments of this utility model provide a cargo platform, including a cargo platform body, a cargo loading and unloading mechanism on the cargo platform body, and an airbag-type cargo platform stabilization mechanism as described in the first aspect.

[0011] Optionally, at least one airbag-type cargo platform stabilization mechanism is provided on both sides of the cargo platform.

[0012] Optionally, the top rods of the corresponding airbag-type cargo platform stabilization mechanisms on both sides of the cargo platform are coaxially arranged.

[0013] Thirdly, embodiments of this utility model provide a handling device, including a mother car, which is connected to a loading platform via a lifting belt mechanism, and the loading platform is the loading platform described in the second aspect.

[0014] Fourthly, embodiments of this utility model provide a storage system including multiple rows of shelves, with aisles formed between adjacent shelves. The aisles are equipped with the handling device described in the third aspect, wherein the mother car is equipped with a traveling mechanism that cooperates with the tracks set on the shelves on both sides of the aisle.

[0015] The beneficial effects of this utility model are as follows: 1. The stabilizing mechanism for a loading platform of this utility model includes a housing, within which an airbag is installed. The airbag is connected to one end of a push rod, which is slidably connected to the housing. An elastic element is provided between the push rod and the housing. When the airbag is inflated, it expands, causing the push rod to extend and the fixed head to contact the shelf. When the airbag deflates, it contracts, and under the action of the elastic element, the push rod contracts, and the fixed head contacts the shelf. The airbag drives the push rod to extend and retract. Because the airbag is a flexible element, a flexible collision occurs between the push rod and the shelf. The airbag can buffer the collision force between the push rod and the shelf, preventing damage to the push rod, extending its service life, and reducing subsequent maintenance costs. Furthermore, the airbag is located inside the housing, which protects it, preventing external dust from affecting its operation. The airbag can also operate normally in high or low temperature environments, improving the environmental adaptability of the entire loading platform stabilizing mechanism.

[0016] 2. The stabilizing mechanism of the loading platform of this utility model uses an electromagnetic suction head for the fixing head. After the fixing head comes into contact with the shelf, the electromagnetic suction head can be energized and generate an adsorption force between it and the shelf, thereby improving the stability of the connection between the fixing head and the shelf, avoiding the shaking of the loading platform, and improving the loading platform's adaptability to the environment. Attached Figure Description

[0017] The accompanying drawings, which form part of this application, are used to provide a further understanding of this application. The illustrative embodiments of this application and their descriptions are used to explain this application and do not constitute a limitation thereof.

[0018] Figure 1 This is a front view of the overall structure of Embodiment 1 of this utility model; Figure 2 This is a top view of the overall structure of Embodiment 1 of this utility model; The components include: 1. shell, 2. airbag, 3. top rod, 4. fixing head, 5. vacuum pump, 6. spring, 7. baffle, and 8. cargo platform body. Detailed Implementation Example 1 This embodiment provides an airbag-type cargo platform stabilization mechanism, which is installed on the cargo platform. When the cargo platform is picking up or placing goods, the stabilization mechanism abuts against the shelves on both sides of the cargo platform to ensure the stability of the cargo platform when picking up or placing goods, thereby enabling the picking up and placing of goods to be carried out smoothly.

[0019] like Figures 1-2 As shown, the airbag-type cargo platform stabilization mechanism includes a housing 1, which is fixedly connected to the cargo platform. A sealed cavity is formed inside the housing 1, and an airbag 2 is provided inside the cavity. One end of the airbag 2 is connected to one end of the top rod 3, and the other end of the airbag 2 is fixedly connected to the inner side of the housing wall of the housing 1.

[0020] In this embodiment, the airbag 2 is made of nylon or polyester material, and its working temperature is -40℃ to 120℃. The airbag can work reliably under extremely cold or hot conditions.

[0021] The push rod 3 extends out of the housing 1 through a through hole in the housing wall and is slidably connected to the housing wall of the housing 1, using the housing wall of the housing 1 to guide the movement direction of the push rod 2.

[0022] The end of the top rod 2 that extends outside the housing 1 is provided with a fixing head 4, which is used to abut against the shelf to maintain the stability of the loading platform.

[0023] The airbag 2 is provided with an inflation / deflation port, which is connected to one end of an air tube. The air tube extends to the outside of the housing 1 and is connected to an inflation / deflation pump, which is used to install on the cargo platform.

[0024] Furthermore, to ensure a tight seal between the air inlet / outlet and the air pipe, a sealing ring is provided between the side of the air pipe and the air inlet / outlet.

[0025] Preferably, a rubber ring can be used as the sealing ring, which will not be described in detail here.

[0026] In this embodiment, the inflation / deflation pump is a vacuum pump 5, which can be an existing device. Its specific structure will not be described in detail here. The vacuum pump 5 can both extract gas from the airbag and inflate gas into the airbag 2.

[0027] Furthermore, the air pipe is also equipped with a switching valve for controlling the opening and closing of the air pipe. Preferably, the switching valve is an electrically controlled switching valve, such as an electrically controlled ball valve or an electrically controlled butterfly valve. The electrically controlled switching valve is connected to the control system and can receive instructions from the control system to operate. At the same time, the vacuum pump is connected to the control system and can also receive instructions from the control system to operate.

[0028] The elastic element is a spring 6, which is sleeved on the outer periphery of the top rod. One end of the spring 6 is connected to the top rod 3, and the other end is fixedly connected to the inner side of the shell wall of the housing 1 through which the top rod 3 passes.

[0029] Specifically, the top rod 3 is equipped with a baffle 7, one end of the spring 6 is fixedly connected to the baffle 7, and the other end is fixedly connected to the shell wall of the housing 1.

[0030] The end of the top rod 3 that extends outside the housing 1 is provided with a fixing head 4, which is used to abut against the shelf.

[0031] Preferably, the top rod 3 and the fixing head 4 are coaxially arranged.

[0032] In one embodiment, the fixing head 4 is a metal block, and its end face that abuts against the shelf is provided with a flexible pad. Preferably, the flexible pad is a rubber pad. With the top rod 3 extended, the metal block can abut against the shelf via a rubber pad, thereby stabilizing the loading platform.

[0033] In another embodiment, the fixing head 4 is an electromagnetic suction head, which is connected to a power supply via a power supply line. The power supply is used to install the device on the loading platform.

[0034] When the fixing head 4 comes into contact with the shelf, the power supply energizes the electromagnetic chuck, generating an electromagnetic attraction force between the electromagnetic chuck and the shelf. This increases the friction between the electromagnetic chuck and the shelf, making the connection between the fixing head and the shelf more stable. This ensures the stability of the loading platform when picking up and placing goods and improves the platform's adaptability to complex environments.

[0035] Furthermore, in order to facilitate control of the direction of airbag 2's contraction and expansion, airbag 2 is composed of multiple airbag sections arranged together, with the multiple airbag sections distributed along the extension and retraction direction of the top rod 3, and adjacent airbag sections interconnected.

[0036] Preferably, the cross-sectional dimensions of each airbag gradually decrease along the directions of both ends of the middle phase. This structural form can control the direction of airbag expansion and contraction, so as to control the direction of movement of the push rod.

[0037] The working method of the cargo platform stabilization mechanism in this embodiment is as follows: During the movement of the loading platform, the airbag 2 does not inflate, and the push rod 3 is in a retracted state under the action of the spring 6.

[0038] When the loading platform moves to the target location, the control system opens the electric control switch valve on the air pipe and simultaneously controls the vacuum pump 5 to inflate the space inside the air bag 2. The air bag 2 expands, causing the top rod 3 to extend outward against the elastic force of the spring 6 until the fixing head 4 abuts against the shelf. When the fixing head 4 is an electromagnetic suction head, after the fixing head 4 abuts against the shelf, the electromagnetic suction head is energized, and an adsorption force is generated between the fixing head 4 and the shelf.

[0039] After the loading platform completes the loading and unloading of goods, the control system controls the vacuum pump 5 to extract the gas from the airbag 2. The airbag 2 contracts, and under the elastic force of the spring 6, the top rod 3 contracts, and the fixing head 4 releases its contact with the shelf. At this time, the loading platform can move freely.

[0040] When the fixing head 4 uses an electromagnetic suction head, before using the vacuum pump 5 to extract the gas from the air bag 2, the power to the fixing head 4 needs to be turned off to release the electromagnetic attraction between the fixing head 4 and the shelf, and then the vacuum pump 5 is started to extract the gas from the air bag 2.

[0041] The loading platform stabilization mechanism of this embodiment uses airbag 2 to drive the top rod 3 to extend and retract. Since airbag 2 is a flexible component, a flexible collision occurs between the fixing head 4 and the shelf. Airbag 2 can buffer the collision force between the fixing head 4 and the shelf, avoiding damage to the top rod 3, extending the service life of the top rod 3, and reducing subsequent maintenance costs. At the same time, airbag 2 is set inside the housing 1, and the housing 1 protects airbag 2. External dust will not affect the operation of airbag 2. Airbag 2 can work normally in high or low temperature environments, improving the environmental adaptability of the entire loading platform stabilization mechanism.

[0042] Example 2 This embodiment provides a loading platform, including a loading platform body 8. The loading platform body 8 is provided with a loading and unloading mechanism. The loading and unloading mechanism adopts an existing telescopic loading and unloading mechanism, including a bidirectional telescopic mechanism. The end of the bidirectional telescopic mechanism is provided with a fork mechanism. The bidirectional telescopic mechanism can drive the fork mechanism to perform bidirectional telescopic movement. The fork mechanism can output swinging movement in the vertical plane. The bidirectional telescopic mechanism can use the fork mechanism to move goods to the loading platform body, or move goods on the loading platform body to the target storage location on the shelf.

[0043] The bidirectional telescopic mechanism and the shift fork mechanism can be based on existing technologies. For example, the bidirectional telescopic mechanism can adopt the telescopic mechanism disclosed in patent application CN117585346A, and the shift fork mechanism can adopt the shift fork mechanism disclosed in patent application CN117585346A.

[0044] In another embodiment, the picking and placing mechanism may also be a bidirectional telescopic suction cup picking and placing mechanism, etc. Those skilled in the art can set it according to actual needs, and it will not be described in detail here.

[0045] In this embodiment, the picking and placing mechanism can adopt the existing technology of current handling devices, and its further technical details will not be described in detail here.

[0046] The loading platform body 8 is provided with the airbag-type loading platform stabilization mechanism described in Embodiment 1. The housing 1 of the loading platform stabilization mechanism is fixedly connected to the loading platform body 8. In this embodiment, at least one airbag-type loading platform stabilization mechanism is provided on each of the two sides parallel to the horizontal movement direction of the loading platform body 8.

[0047] Preferably, each side is provided with two airbag-type cargo platform stabilizing mechanisms as described in Embodiment 1. For the two airbag-type cargo platform stabilizing mechanisms on one side, the two airbag-type cargo platform stabilizing mechanisms are respectively located at the two ends of the side of the cargo platform body 8.

[0048] In the airbag-type cargo platform stabilization mechanisms on both sides, the top rods 3 of the corresponding airbag-type cargo platform stabilization mechanisms are coaxially arranged.

[0049] All airbag-type cargo platform stabilization mechanisms share a single vacuum pump 5. The vacuum pump is installed on the cargo platform body 8 and can drive the four airbag-type cargo platform stabilization mechanisms to operate synchronously. The installation position of the vacuum pump 5 on the cargo platform body 8 can be set according to actual needs, and will not be described in detail here.

[0050] It is understood that those skilled in the art can set the number and position of the airbag-type cargo platform stabilization mechanism according to actual needs, which will not be described in detail here.

[0051] This embodiment only improves the stabilizing mechanism of the loading platform; the rest of the loading platform structure can use existing technology and will not be described in detail here.

[0052] Example 3 This embodiment provides a handling device, including a mother car, which is connected to a loading platform via a lifting belt mechanism. The loading platform is the loading platform described in Embodiment 2. The mother car includes a car body, which is equipped with a traveling mechanism for cooperating with the rails set on the shelf. The lifting belt mechanism includes a hoisting mechanism installed on the car body, which is connected to the loading platform body via the lifting belt and can drive the loading platform body to move up and down.

[0053] The mother car and the lifting belt mechanism can be based on existing technology, and their specific structures will not be described in further detail here.

[0054] Example 4 This embodiment provides a storage system including multiple rows of shelves, with aisles formed between adjacent rows of shelves. The aisles are equipped with the handling device described in Embodiment 3. Specifically, the tops of the shelves on both sides of the aisle are provided with rails, and the traveling mechanism of the mother car cooperates with the rails.

[0055] The remaining structure of the warehousing system can be achieved using existing technologies, and will not be described in detail here.

[0056] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
