Abstract
Description
Technical Field
[0001] This utility model relates to the field of stacker crane technology, and in particular to an oiling device and a stacker crane. Background Technology
[0002] In modern logistics and warehousing systems, stacker cranes play a crucial role, serving as one of the core pieces of equipment for achieving efficient warehousing operations. They are responsible for the rapid and accurate handling of goods within the warehouse, and their operational stability and efficiency directly determine the overall performance of the warehousing system. The stacker crane's chain, as a key component for transmitting power and handling goods, is constantly subjected to friction and tensile forces during prolonged high-intensity operation. Without proper and continuous lubrication, the chain is prone to accelerated wear, which not only increases operating resistance and energy consumption but also significantly shortens its lifespan and may even lead to safety accidents, disrupting the normal operation of the entire warehousing process.
[0003] Traditional manual lubrication methods have several drawbacks. Firstly, manual lubrication requires stopping the machine, interrupting the stacker crane's workflow and reducing warehousing efficiency. Secondly, manual lubrication makes it difficult to guarantee timely lubrication and uniform oil distribution. In practice, operators may fail to lubricate the chain promptly for various reasons, causing the chain to run in a dry state and accelerating wear. Furthermore, it's difficult to precisely control the amount of oil during manual lubrication, easily resulting in over- or under-lubrication. Over-lubrication wastes lubricant, increases operating costs, and excess oil may drip onto the warehouse floor or goods, causing environmental and cargo contamination; under-lubrication fails to meet the chain's lubrication needs, similarly affecting equipment performance.
[0004] Existing automatic lubrication devices can only lubricate single-row chains, while typical stacker cranes have two or three chains, requiring two or more lubrication devices, resulting in more parts.
[0005] Therefore, there is an urgent need to design an oiling device and a stacker crane to solve the above problems. Utility Model Content
[0006] One objective of this invention is to provide an oiling device that can continuously oil at least two chains simultaneously, reducing the number of parts and making operation convenient.
[0007] Another objective of this invention is to provide a stacker crane in which the same lubrication device simultaneously lubricates at least two chains of the stacker crane, thereby reducing the number of lubrication devices, lowering costs, and facilitating operation.
[0008] To achieve this objective, the present invention adopts the following technical solution:
[0009] The lubrication device includes an oil tank, a first oil pipe, a lubrication assembly, and an oil distributor. The oil distributor has one inlet and at least two outlets. The oil tank is connected to the inlet via the first oil pipe. One end of the lubrication assembly is connected to both outlets simultaneously, and the other end of the lubrication assembly is in contact with at least two chains simultaneously. The height of the oil tank is higher than the height of the end of the lubrication assembly.
[0010] As an alternative, the aforementioned lubrication assembly includes a second oil pipe and an oil dispersing component. The aforementioned lubrication device also includes a frame, the aforementioned oil dispersing component is connected to the aforementioned frame, the free end of the aforementioned oil dispersing component abuts against the aforementioned chain, each of the aforementioned outlets is connected to one of the aforementioned second oil pipes, the end of the aforementioned second oil pipes extends into the interior of the aforementioned oil dispersing component, and the aforementioned oil dispersing component is made of any one of flexible material, porous material or brush.
[0011] As an optional solution, the aforementioned oil distribution component is a three-way valve, and the aforementioned second oil pipe is provided in two parts.
[0012] As an alternative, the first oil pipe and the second oil pipe mentioned above are made of rubber.

[0021] The beneficial effects of this utility model are as follows:
[0022] This utility model provides an oil lubrication device. Taking two outlets as an example, the height of the oil tank is higher than the height of the end of the oil lubrication assembly. Under the action of gravity, the oil passes through the first oil pipe. Due to the action of the oil distributor, the oil enters from the inlet and exits from the two outlets. The oil lubrication assembly is connected to both outlets at the same time. The oil is specifically divided into two paths within the oil lubrication assembly. At the end of the oil lubrication assembly, corresponding to the inlet position, the oil distribution is greater than at other positions. Through the setting of the oil distributor and the oil lubrication assembly, the two chains can be fully lubricated simultaneously and specifically. The number of parts is reduced, and the failure rate is low due to the simple gravity principle.
[0023] This utility model also provides a stacker crane, which uses the above-mentioned lubrication device to simultaneously lubricate at least two chains of the stacker crane with the same lubrication device, reducing the number of lubrication devices, lowering costs, and making operation convenient.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0033] This embodiment provides a lubrication device. In this embodiment, the lubrication device is used inside a stacker crane. In other embodiments, it can be used on chains 200 of other equipment that require lubrication; this is not limited to these applications. In this embodiment, a stacker crane is used as an example. The stacker crane has two chains 200 arranged side by side. Of course, three or more chains can also be arranged. The lubrication device can lubricate at least two chains 200 simultaneously, reducing the number of parts and facilitating operation. Figures 1-3 As shown, the lubrication device includes an oil tank 10, a first oil pipe 30, a lubrication assembly 40, and an oil distributor 50. The oil distributor 50 has an inlet 51 and at least two outlets 52. The oil tank 10 is connected to the inlet 51 via the first oil pipe 30. One end of the lubrication assembly 40 is connected to both outlets 52, and the other end of the lubrication assembly 40 is in contact with at least two chains 200. The height of the oil tank 10 is higher than the height of the end of the lubrication assembly 40.
[0034] Taking the above-mentioned lubrication device with two outlets 52 as an example, the height of the oil tank 10 is higher than the height of the end of the lubrication assembly 40. Under the action of gravity, the oil passes through the first oil pipe 30. Due to the action of the oil distributor 50, the oil enters from the inlet 51 and exits from the two outlets 52. The lubrication assembly 40 is connected to both outlets 52 at the same time. The oil is specifically divided into two paths in the lubrication assembly 40. At the end of the lubrication assembly 40, the position corresponding to the inlet 51 is specifically targeted. The amount of oil distributed is more than in other positions. Through the setting of the oil distributor 50 and the lubrication assembly 40, the two chains 200 can be fully lubricated simultaneously and specifically. The number of parts is reduced, and the failure rate is low due to the simple gravity principle.
[0035] Of course, in other embodiments, there may be three or more outlets 52, which can be flexibly set according to the number of chains 200. In the following description, two outlets 52 are used as examples. The structure for the corresponding number of outlets is the same, and will not be repeated hereafter.
[0036] Optionally, such as Figure 1 As shown, a switch valve 20 is provided on the first oil pipe 30. During maintenance or shutdown, the switch valve 20 can be closed to avoid oil waste.
[0037] Optionally, such as Figure 2 As shown, the lubrication assembly 40 includes a second oil pipe 42 and an oil dispersing component 41. The lubrication device also includes a frame 70, with the oil dispersing component 41 connected to the frame 70. The free end of the oil dispersing component 41 abuts against the chain 200. Each outlet 52 is connected to a second oil pipe 42, the end of which extends into the interior of the oil dispersing component 41. The oil dispersing component 41 is made of any one of flexible material, porous material, or a brush. With the above arrangement, oil exits from the two outlets 52 and enters the two second oil pipes 42 respectively. The ends of the second oil pipes 42 are inserted into the oil dispersing component 41, which disperses the oil, spreading it at the end of the component and ensuring uniform lubrication.
[0038] In this embodiment, the oil dispersing component 41 is a brush. On the one hand, brushes are relatively easy to obtain in the factory, and on the other hand, the density of the brush prevents the oil from dripping.
[0039] In other embodiments, the oil dispersing component 41 may also be a sponge or a towel-like object, which is not limited here.
[0040] Optionally, a flow valve is installed at the oil inlet of the first oil pipe 30 to the oil distribution component 50. This allows for convenient control of the flow rate entering the oil distribution component 41. It should be noted that before use, the lubrication flow rate of the stacker crane at different speeds and loads needs to be obtained through testing, and different flow rates can be selected according to different operating conditions.
[0041] Optionally, the flow valve is integrated into the oil distributor 50. It is understood that in this embodiment, the oil distributor 50 is in the form of a three-way valve. When integrated with the flow valve, it forms a three-way valve, which is relatively easy to procure.
[0042] Optionally, the flow valve is a manually adjustable valve, which can be easily adjusted by on-site personnel based on parameters or experience.
[0043] Optionally, such as Figure 1 As shown, the frame 70 consists of the first frame 71 and the second frame 72. Both the first frame 71 and the second frame 72 are the frames 70 of the stacker crane itself. The oil tank 10 is installed on the first frame 71, and the oil dispersing component 41 is installed on the second frame 72.
[0044] The flow valve knob 80 is installed on the second frame 72 for easy manual turning. The principle of adjusting the flow of the flow valve by turning the knob 80 is existing technology and will not be elaborated here.
[0045] In other embodiments, an electronic valve can also be set. The operator inputs parameters on the operation panel, and the host computer controls the flow of the electronic valve. In this case, the oil distribution component 50 can be a three-way valve, and the electronic valve is set in the first oil pipe 30.
[0046] Optionally, the oil distributor 50 is fixedly connected to the frame 70, and the height of the oil tank 10 relative to the frame 70 is adjustable. On the one hand, fixing the oil distributor 50 prevents the first oil pipe 30 and the second oil pipe 42 connected to it from shaking, causing unstable lubrication and avoiding changes in the height of the oil distributor 50 and the oil tank 10 during use; on the other hand, the adjustable height of the oil tank 10 facilitates finding a suitable height difference between the two during the debugging process.
[0047] Furthermore, the first unit 71 is equipped with a clamp that surrounds the fuel tank 10. Loosening the clamp allows for adjustment of the height of the fuel tank 10.
[0048] Optionally, the height difference between the oil tank 10 and the end of the lubrication assembly 40 (i.e., the end of the second oil pipe 42) is between 8 cm and 12 cm, which can achieve good gravity effect, and the oil can automatically descend within this range. The specific height can be determined based on actual experiments.
[0049] Optionally, the first oil pipe 30 and the second oil pipe 42 are made of rubber, which has good corrosion resistance, ensuring the long-term use of the first oil pipe 30 and the second oil pipe 42.
[0050] Optionally, the exterior of the first oil pipe 30 and the second oil pipe 42 is coated with a protective paint, which has good oil resistance and dust resistance.
[0051] Optionally, a protective sleeve is fitted over the bent portion of the first oil pipe 30 to prevent mechanical damage, and a protective baffle is installed around the first oil pipe 30 to prevent the oil pipe from colliding with other hard objects. During routine maintenance, the protective measures of the first oil pipe 30 are regularly checked for integrity, and any damage is promptly repaired or replaced to effectively protect the first oil pipe 30.
[0052] The stacker crane in this embodiment includes the above-mentioned lubrication device. By using the above-mentioned lubrication device, the stacker crane can simultaneously lubricate at least two chains 200 of the stacker crane with the same lubrication device, thereby reducing the number of lubrication devices, reducing costs, and making operation convenient.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
