[0039] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings. It is worth noting that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] Example:

[0041] See also Figure 1 , a suspended hoist comprises a mounting portion 1 and a cargo platform.

[0042] See also Figure 1 In this embodiment, the mounting portion 1 is fixedly mounted on the top of the shelf 2 .

[0043] See also Figure 1 and Figure 2 The mounting portion 1 is connected to the cargo platform via a suspension mechanism, and the suspension mechanism is used to adjust the height of the cargo platform.

[0044] The suspension mechanism includes at least one drive motor 31 and a plurality of winches 32. In this embodiment, the drive motor 31 can be a servo motor. Figure 4 Each winch wheel 32 is matched with a driving motor 31, the driving motor 31 is fixedly installed in the mounting part 1, the output end of the driving motor 31 is fixedly connected to the winch wheel 32, a winding member is wound on the winch wheel 32, the winding member can be a belt 33 or a steel belt or a rope, the rope can be a steel wire rope, and the winding member is fixedly connected to the cargo platform. The servo motor, the winch wheel 32, the steel belt, the belt 33, and the steel wire rope are all existing products, and the materials are easy to obtain.

[0045] The working principle of the suspension mechanism is: the driving motor 31 is used to drive the winch wheel 32 to rotate forward or reverse; when the driving motor 31 drives the winch wheel 32 to rotate forward, the winding member wound on the winch wheel 32 is released, so that the height of the cargo platform is lowered; when the driving motor 31 drives the winch wheel 32 to reverse, the winch wheel 32 reels the winding member, so that the height of the cargo platform is increased.

[0046] like Figure 3 and Figure 4 As shown, the suspension mechanism is installed on the mounting portion 1, and the end of the winding member is installed on the cargo platform. In addition to this installation method, another possible implementation method is: the suspension mechanism is installed on the cargo platform, and the end of the winding member is installed on the mounting portion 1.

[0047] From the above introduction, it can be known that in this embodiment, because the mounting part 1 is mounted on the top of the shelf 2, the mounting part 1 is connected to the cargo platform through a suspension mechanism, and the suspension mechanism is used to adjust the height of the cargo platform. Compared with the background technology, the frame assembly operation is omitted, the structure is simplified, the assembly is convenient, and manpower is saved. In addition, during the subsequent modification, there is no frame structure to block and hinder, which reduces the difficulty of the subsequent modification operation.

[0048] As a further improvement, this embodiment further includes a posture detection element. The posture detection element uses a gyroscope or a laser rangefinder. When a gyroscope is used, the gyroscope is installed on the cargo platform. When other posture detection elements such as a laser rangefinder are used, they can be installed on the cargo platform and / or the mounting portion 1. The posture detection element is used to detect the posture of the cargo platform during operation.

[0049] As a further improvement, in this embodiment, a stabilizing mechanism is provided between the cargo platform and the shelf 2, and the stabilizing mechanism is used to keep the cargo platform stable when the cargo platform is docked with goods.

[0050] The stabilizing mechanism includes a guide frame, and the guide frame includes at least a straight guide rail 41. In this embodiment, see Figure 1 and Figure 2 Two linear guide rails 41 are symmetrically arranged, and 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 arrangement of the retaining rod 42 can ensure the stability of the two linear guide rails 41 and reduce the risk of deformation of the linear guide rails 41.

[0051] The cargo platform is provided with a guide structure, which is one of a slider, a clamping wheel and a groove wheel or a combination of several of them. When a slider is used, the slider is fixedly mounted on the side of the cargo platform, and the slider slides with the linear guide rail 41 in the vertical direction. When the clamping wheel 5 is used, see Figure 3 The clamping wheel 5 refers to a plurality of wheels with a linear guide rail 41 in the middle. The clamping wheel 5 is installed on the side of the cargo platform. The clamping wheel 5 rolls with the linear guide rail 41 in the vertical direction. In addition, the groove wheel, which can also be called the snap-in wheel, means that the groove on the wheel surface of the groove wheel itself can be snapped on the linear guide rail 41. The snap-in wheel can be a positive snap-in wheel or an oblique snap-in wheel. When the oblique snap-in wheel is used, the four oblique snap-in wheels are respectively arranged on the four corners of the cargo platform. When the positive snap-in wheel is used, the four positive snap-in wheels are respectively arranged on the four sides of the cargo platform.

[0052] The working principle of a suspended hoist in the present embodiment is: the suspension mechanism drives the cargo platform to rise and fall by winding or releasing the winding member, and the cargo platform carries the guide structure to rise and fall together, and 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 cargo platform from shaking during the lifting process, thereby improving the stability of the cargo platform and facilitating the improvement of transportation stability.

[0053] The stability of the cargo platform is maintained by using a guide frame and a guide structure, and the structure is simple and reliable, which is conducive to improving assembly efficiency and saving costs.

[0054] When the cargo 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 and will not limit the lifting and lowering travel of the cargo platform, which is conducive to improving the flexibility of use.

[0055] Another implementation structure of the stabilizing mechanism is: the stabilizing mechanism includes a supporting mechanism, see Figure 8 , the supporting mechanism is installed on the cargo platform, and the supporting mechanism includes a fixed part and a telescopic part 7. The telescopic part 7 can adopt a telescopic mechanism such as an electric cylinder or a pneumatic cylinder, and the telescopic part 7 is fixedly installed on the cargo 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 bracket on the conveyor line, or fixedly installed on the ground. When the cargo platform is docked with goods, the telescopic part 7 is extended and pressed against the fixed part, which can maintain the stability of the cargo platform at this time, prevent the cargo platform from shaking, and improve the accuracy and reliability of the cargo platform when docking with goods; when the cargo platform does not need to be docked with goods, the telescopic part 7 is shortened and leaves the fixed part, and the suspension mechanism can adjust the height of the cargo platform.

[0056] Because the cargo platform is raised and lowered by utilizing the mounting portion 1 located on the top of the shelf 2 and the suspension mechanism installed on the mounting portion 1, the space above the shelf 2 can be fully utilized without using the space near the ground, thereby allowing the cargo platform to be moved to the bottom of the shelf 2, making it convenient for the cargo platform to transport the goods located at the bottom of the shelf 2, thereby helping to improve flexibility of use.

[0057] In addition, in a suspended elevator of the present embodiment, the cargo platform is one of a flat plate structure, a powered roller structure, an unpowered roller structure, a conveyor belt structure and a conveyor chain structure, and the cargo platform is used to dock the transfer platform and the conveying robot, and the transfer platform is one of a flat plate structure, a powered roller structure, an unpowered roller structure, a conveyor belt structure and a conveyor chain structure.

[0058] See also Figure 5 The cargo platform adopts a roller conveyor 6, which is a form of roller structure. The roller conveyor 6 includes an unpowered roller conveyor and a powered roller conveyor. Figure 6 Shown is a roller conveyor with a telescopic pickup structure. Figure 7 Shown is a flexible roller conveyor with a telescopic pickup structure, where the spacing between the two roller sections is adjustable. Figure 6 and Figure 7 The difference is that Figure 6 The roller length cannot be adjusted. Figure 7 The roller length is adjustable. Figure 5 , Figure 6, Figure 7 The cargo platforms shown are all existing products and are easy to use.

[0059] When there is a power mechanism on the shelf 2 to take away the goods (such as the material box 61) on the loading platform, the loading platform can use an unpowered roller conveyor, and the unpowered roller conveyor does not need to actively transport the goods to the shelf 2.

[0060] When there is no power mechanism on the shelf 2 to take away the goods on the loading platform, the loading platform can use a powered roller conveyor.

[0061] The powered roller conveyor can actively drive the rollers to rotate, thereby actively conveying the goods to the shelf 2.

[0062] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
