[0001] Cross-reference to related applications

[0002] This disclosure claims priority to Chinese Patent Application No. 2024216462828, filed on July 11, 2024, entitled “A Suspension Lifting Machine”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of hoisting technology, specifically to a suspended hoisting machine. Background Technology

[0004] Elevators are used to lift goods from a low place to a high place, and are suitable for vertical transport of goods, especially in factories, warehouses, logistics centers, and other similar locations. Types of elevators include bucket elevators, plate elevators, and suspended elevators.

[0005] Current hoists are basically frame-type structures, meaning the hoist is supported by a rectangular frame, within which a loading platform is installed. The loading platform moves up and down within the rectangular frame via a lifting mechanism. When installing this type of hoist on-site, the frame and other lifting components need to be assembled, requiring a significant investment of manpower and also posing considerable challenges to subsequent modifications.

[0006] Public content

[0007] This disclosure addresses the aforementioned shortcomings of the existing technology by proposing a suspended hoist, which facilitates assembly, saves manpower, and reduces the difficulty of subsequent modification work.

[0008] To achieve the above objectives, the technical solution adopted in this disclosure is as follows:

[0009] A suspended hoist includes an installation section and a loading platform. The installation section is fixed on a shelf, and the installation section and the loading platform are connected by a suspension mechanism, which is configured to adjust the height of the loading platform.

[0010] Optionally, a stabilizing mechanism is provided between the loading platform and the shelf, the stabilizing mechanism being configured to maintain the stability of the loading platform when goods are docked on the loading platform.

[0011] Optionally, the stabilizing mechanism includes a guide frame disposed on the shelf, and a guide structure is provided on the loading platform, the guide structure cooperating with the guide frame in the vertical direction.

[0012] Optionally, the guide frame includes at least one straight guide rail, and the guide structure is one or a combination of slider, clamping wheel and grooved wheel.

[0013] Optionally, the stabilizing mechanism includes a support mechanism disposed on the loading platform. The support mechanism includes a fixed part and a telescopic part. When the loading platform docks with goods, the telescopic part extends and presses against the fixed part to prevent the loading platform from shaking.

[0014] Optionally, the suspension mechanism is mounted on the mounting portion.

[0015] Optionally, the suspension mechanism is mounted on the cargo platform.

[0016] Optionally, the suspension mechanism includes at least one drive motor and multiple winches, the output end of the drive motor is connected to the winches, and the winches are connected to the loading platform through a winding member.

[0017] Optionally, the winding element is one of a belt, a steel strip, and a rope.

[0018] Optionally, when the suspension mechanism is mounted on the mounting portion, the end of the winding member is connected to the cargo platform.

[0019] Optionally, when the suspension mechanism is mounted on the loading platform, the end of the winding member is connected to the mounting portion.

[0020] Optionally, the drive motor is a servo motor, and each winch is connected to a servo motor.

[0021] Optionally, it also includes an attitude detection element configured to detect the attitude of the loading platform during operation.

[0022] Optionally, the attitude detection element is a gyroscope mounted on the cargo platform.

[0023] Optionally, the attitude detection element is a laser rangefinder.

[0025] The beneficial effects of the embodiments disclosed herein include, for example:

[0026] Because the mounting unit is installed at the top of the shelf, and is connected to the loading platform via a suspension mechanism that adjusts the height of the loading platform, compared to the prior art, it eliminates the need for frame assembly, simplifies the structure, facilitates assembly, and saves manpower. Furthermore, the absence of a frame structure obstructs subsequent modifications, reducing the difficulty of such modifications. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of this disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely to illustrate selected embodiments of the disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] In the description of this disclosure, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing this disclosure and simplifying the description, 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, and therefore should not be construed as a limitation of this disclosure.

[0041] Furthermore, the terms "first," "second," and "third" are configured only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0042] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0043] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0044] It should be noted that, where there is no conflict, the features in the embodiments of this disclosure can be combined with each other. Optionally, referring to FIG1, a suspended hoist includes a mounting part 1 and a loading platform.

[0045] Referring to Figure 1, in this embodiment, the mounting part 1 is fixedly mounted on the top of the shelf 2.

[0046] Referring to Figures 1 and 2, the mounting unit 1 is connected to the loading platform via a suspension mechanism, which is configured to adjust the height of the loading platform.

[0047] The suspension mechanism includes at least one drive motor 31 and multiple winches 32. In this embodiment, the drive motor 31 can be a servo motor. Referring to Figure 4, each winch 32 is matched with one drive motor 31. The drive motor 31 is fixedly mounted on the mounting part 1, and the output end of the drive motor 31 is fixedly connected to the winch 32. A winding component is wound on the winch 32. The winding component can be a belt 33, a steel belt, or a rope. The rope can be a steel wire rope. The winding component is fixedly connected to the loading platform. The servo motor, winch 32, steel belt, belt 33, and steel wire rope are all existing products and are readily available.

[0048] The working principle of the suspension mechanism is as follows: the drive motor 31 is configured to drive the winch 32 to rotate forward or in reverse; when the drive motor 31 drives the winch 32 to rotate forward, the winding material wrapped on the winch 32 is released, which lowers the height of the loading platform; when the drive motor 31 drives the winch 32 to rotate in reverse, the winch 32 winds up the winding material, which raises the height of the loading platform.

[0049] As shown in Figures 3 and 4, the suspension mechanism is mounted on the mounting section 1, and the end of the winding component is mounted on the loading platform. Besides this mounting method, another possible implementation is: the suspension mechanism is mounted on the loading platform, and the end of the winding component is mounted on the mounting section 1.

[0050] As described above, in this embodiment, because the mounting part 1 is installed on the top of the shelf 2, and the mounting part 1 is connected to the loading platform through a suspension mechanism, which is configured to adjust the height of the loading platform, compared with the prior art, the frame assembly work is eliminated, the structure is simplified, assembly is convenient, and manpower is saved. Furthermore, in subsequent modifications, there is no frame structure obstructing the view, reducing the difficulty of subsequent modification work.

[0051] Optionally, this embodiment also includes an attitude detection element. The attitude detection element is a gyroscope or a laser rangefinder. When a gyroscope is used, it is mounted on the loading platform. When other attitude detection elements, such as a laser rangefinder, are used, they can be mounted on the loading platform and / or mounting section 1. The attitude detection element is configured to detect the attitude of the loading platform during operation.

[0052] Optionally, in this embodiment, a stabilizing mechanism is provided between the loading platform and the shelf 2. The stabilizing mechanism is configured to maintain the stability of the loading platform when it docks with the shelf 2.

[0053] The stabilizing mechanism includes a guide frame, which includes at least one linear guide rail 41. In this embodiment, referring to Figures 1 and 2, two linear guide rails 41 are symmetrically arranged. The two linear guide rails 41 are fixedly installed on the shelf 2. A retaining rod 42 is fixedly connected to the top of the two linear guide rails 41. The retaining rod 42 ensures the stability of the two linear guide rails 41 and reduces the risk of deformation. The number of linear guide rails 41 can also be three, four, or more. Multiple linear guide rails 41 are all fixedly installed on the shelf 2, and the multiple linear guide rails 41 are arranged side by side with intervals. The number of linear guide rails 41 is determined according to specific circumstances and is not limited here.

[0054] The loading platform is equipped with a guide structure, which is one or a combination of sliders, clamping wheels, and grooved wheels. When using sliders, the sliders are fixedly installed on the side of the loading platform, and the sliders slide in a vertical direction with the linear guide rail 41. When using clamping wheels 5, as shown in Figure 3, clamping wheels 5 refer to several sets of wheels clamping the linear guide rail 41 in the middle. Clamping wheels 5 are installed on the side of the loading platform, and clamping wheels 5 roll in a vertical direction with the linear guide rail 41. In addition, grooved wheels, also known as locking wheels, refer to the grooves on the wheel surface of which can lock onto the linear guide rail 41. Locking wheels can be positive locking wheels or oblique locking wheels. When using oblique locking wheels, four oblique locking wheels are arranged at the four corners of the loading platform. When using positive locking wheels, four positive locking wheels are arranged on the four sides of the loading platform.

[0055] The working principle of a suspended hoist in this embodiment is as follows: the suspension mechanism drives the loading platform to rise and fall by winding or releasing the winding component. The loading platform carries the guide structure and rises and falls together. The guide structure moves along the linear guide rail 41 in the guide frame. The cooperation between the guide structure and the guide frame can prevent the loading platform from swaying during the lifting process, thereby improving the stability of the loading platform and improving the stability of transportation.

[0056] By using guide frames and guide structures to maintain the stability of the loading platform, the structure is simple and reliable, which helps to improve assembly efficiency and save costs.

[0057] As the loading platform moves up and down along the linear guide rail 41 in the guide frame, the linear travel of the linear guide rail 41 is long enough to not restrict the lifting and lowering stroke of the loading platform, which helps to improve the flexibility of use.

[0058] Another implementation of the stabilizing mechanism is as follows: The stabilizing mechanism includes a support mechanism, as shown in Figure 8. The support mechanism is installed on the loading platform and includes a fixed part and a telescopic part 7. The telescopic part 7 can be an electric cylinder, pneumatic cylinder, or other telescopic mechanism, and is fixedly installed on the loading platform. The fixed part refers to a component that is fixedly installed on the shelf 2, or fixedly installed on the transfer platform, or fixedly installed on the support on the conveyor line, or fixedly installed on the ground. When the loading platform connects to goods, the telescopic part 7 extends and presses against the fixed part, which can maintain the stability of the loading platform at this time, prevent the loading platform from shaking, and improve the accuracy and reliability of the loading platform when connecting to goods; when the loading platform does not need to connect to goods, the telescopic part 7 retracts away from the fixed part, and the suspension mechanism can adjust the height of the loading platform.

[0059] Because the loading platform is raised and lowered using the mounting part 1 located at the top of the shelf 2 and the suspension mechanism mounted on the mounting part 1, the space above the shelf 2 can be fully utilized without using the space near the ground. This allows the loading platform to be moved to the bottom of the shelf 2, making it convenient for the loading platform to transport goods located at the bottom of the shelf 2 and improving the flexibility of use.

[0060] Furthermore, in one embodiment of the suspended hoist, the loading platform is one of the following: a flat plate structure, a powered roller structure, a non-powered roller structure, a conveyor belt structure, and a conveyor chain structure. The loading platform is configured as a docking and handover station and a conveying robot. The handover station is one of the following: a flat plate structure, a powered roller structure, a non-powered roller structure, a conveyor belt structure, and a conveyor chain structure.

[0061] Referring to Figure 5, the loading platform uses a roller conveyor 6. A roller conveyor is a type of roller structure, and roller conveyor 6 includes both unpowered and powered roller conveyors. Figure 6 shows a roller conveyor with a telescopic picking structure. Figure 7 shows a flexible roller conveyor with a telescopic picking structure, where the distance between the two roller sections is adjustable. The difference between Figure 6 and Figure 7 is that the roller length in Figure 6 is not adjustable, while the roller length in Figure 7 is adjustable. The loading platforms shown in Figures 5, 6, and 7 are all existing products and are easy to use.

[0062] When there is a powered mechanism on shelf 2 that can remove goods (e.g., bin 61) from the loading platform, the loading platform can be a non-powered roller conveyor, which does not need to actively transport goods to shelf 2.

[0063] When there is no powered mechanism on shelf 2 to remove goods from the loading platform, a powered roller conveyor can be used for the loading platform.

[0064] A powered roller conveyor can actively drive the rollers to rotate, thereby actively transporting goods onto shelf 2.

[0065] Obviously, those skilled in the art can make various modifications and variations to this disclosure without departing from its spirit and scope. Therefore, if such modifications and variations fall within the scope of the claims of this disclosure and their equivalents, this disclosure is also intended to include such modifications and variations. Industrial applicability

[0066] In summary, the embodiments of this disclosure provide a suspended hoist that eliminates the need for frame assembly, simplifies the structure, facilitates assembly, and saves manpower. Furthermore, the absence of a frame structure obstructs subsequent modifications, reducing the difficulty of such modifications.
