[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this embodiment, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this embodiment, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" 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, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0026] In this embodiment of the utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0027] like Figures 1 to 5 As shown, this utility model provides a handling device. The handling device includes: a support frame 1, a traveling mechanism 2, a folding mechanism 3, a hoisting mechanism 4, and a telescopic mechanism 5.

[0028] The walking mechanism 2 is located on the support frame 1; the folding mechanism 3 has a fixed end that is folded together with each other and at least one folding movable end, and the fixed end is located on the support frame 1; the hoisting mechanism 4 is located on the folding movable end and is used to hoist the floor; the first end of the telescopic mechanism 5 is connected to the fixed end of the folding mechanism 3, and the second end of the telescopic mechanism 5 is connected to the folding movable end of the folding mechanism 3.

[0029] Specifically, the support frame 1 serves as the support frame for the device, and the walking mechanism 2, folding mechanism 3, hoisting mechanism 4, and telescopic mechanism 5 are all mounted on the support frame 1. The walking mechanism 2 is located at the bottom of the support frame 1, fulfilling the device's walking and moving function; the folding mechanism 3 has a fixed end and a folding movable end that can be folded and opened, and the telescopic mechanism 5 serves as the power source for the folding mechanism 3. The folding movable end can be folded and opened under the drive of the telescopic mechanism 5, and then the hoisting mechanism 4, which is installed on the folding movable end, drives the floor to be lifted and moved.

[0030] Specifically, the walking mechanism 2 includes four wheels, two of which are omnidirectional wheels, which can control the direction of movement of the device. Furthermore, the wheels and / or omnidirectional wheels are equipped with brake locking components, which enable the transport device to stop and move as needed, significantly improving the floor installation accuracy.

[0031] The folding mechanism 3 has a fixed end and at least one folding movable end. The fixed end is fixedly mounted on the support frame 1 and serves as a support structure for the folding movable end. One or more folding movable ends can be provided depending on the required transport height. If multiple folding movable ends are provided, they are connected sequentially. The folding movable end is located below the fixed end. When the folding mechanism 3 is in the unfolded state, the folding movable end extends downwards, causing the lifting mechanism 4 to descend; conversely, when the folding mechanism 3 is in the folded state, the folding movable end rises upwards, causing the lifting mechanism 4 to rise.

[0032] The lifting mechanism 4 is located on the folding movable end, typically at the far end. The floor is lifted and moved using the lifting mechanism 4. The lifting mechanism 4 can employ lifting pins and hooks, and up to four mechanisms can be installed for stable lifting of the floor. Specifically, the lifting pins are used to connect the device to the floor, fastening them to the threaded holes in the floor with threads. The minimum insertion depth is marked on the lifting pins.

[0033] The telescopic mechanism 5 serves as the power source for the folding movable end of the folding mechanism 3, enabling it to extend and retract, thereby driving the folding movable end to fold relative to the fixed end. Optionally, the telescopic mechanism 5 can employ a pump in conjunction with a push rod to achieve the telescopic movement.

[0034] Furthermore, the conveying device can be equipped with a controller to control the extension and retraction state of the telescopic mechanism 5. The controller can use wireless transmission of control signals to remotely control the telescopic mechanism 5. The controller has both charging and plug-and-play modes (the socket should be labeled and equipped with a protective cover), and can realize raising, lowering, stopping, and emergency stopping. It has upper and lower limits, and after stopping, it has safety protection measures such as self-locking and anti-slip devices to prevent abnormal lowering caused by power failure or mechanical failure. When raising, the upper limit can be freely set.

[0035] This utility model provides a handling device, comprising: a support frame 1, a walking mechanism 2, a folding mechanism 3, a hoisting mechanism 4, and a telescopic mechanism 5. The walking mechanism 2 is mounted on the support frame 1; the folding mechanism 3 has a fixed end folded together and at least one movable folding end, with the fixed end mounted on the support frame 1; the hoisting mechanism 4 is located at the movable folding end and is used to hoist the floor; the first end of the telescopic mechanism 5 is connected to the fixed end of the folding mechanism 3, and the second end of the telescopic mechanism 5 is connected to the movable folding end of the folding mechanism 3. This utility model provides a handling device that moves the device via the walking mechanism 2, drives the movable folding end of the folding mechanism 3 to fold and lift via the telescopic mechanism 5, and utilizes the hoisting mechanism 4 to lift and transport the floor. This handling device replaces the existing method of manually moving floorboards, offering advantages such as high efficiency and reduced risk of personal injury.

[0036] In one embodiment of this utility model, the folding mechanism 3 includes a first linkage unit 31 and a second linkage unit 32. The first end of the first linkage unit 31 is hinged to the support frame 1, and its second end is hinged to the hoisting mechanism 4. The second linkage unit 32 is hinged to the first linkage unit 31 at an intersection, with its first end hinged to the support frame 1 and its second end hinged to the hoisting mechanism 4. Specifically, the folding mechanism 3 is composed of a first linkage unit 31 and a second linkage unit 32 arranged in a cross-shaped and symmetrical manner. These two linkage units form a lifting structure that can be opened and closed. One end of each linkage unit is hinged to the support frame 1, and the other end is hinged to the hoisting mechanism 4. The linkage units are folded by a telescopic mechanism 5. When the two linkage units are folded, the hoisting mechanism 4 rises; when the two linkage units are unfolded, the hoisting mechanism 4 descends.

[0037] It should be understood that the first link unit 31 and the second link unit 32 described above can be composed of multiple links hinged together. In this embodiment, the first end of the first link unit 31 and the second link unit 32 serves as the fixed end of the folding mechanism 3, and the second end serves as the folding movable end. Because the link unit can be composed of multiple links hinged together, it has multiple folding movable ends.

Specifically, the first guide rail 61 is used to mount the first support 62 and the second support 63, and defines the sliding direction of at least one of the two supports, thereby ensuring that the two linkage units can perform folding movements. Preferably, in this embodiment, one support is fixed to the first guide rail 61, and the other support is slidably mounted on the first guide rail 61 and can move along the first guide rail 61.

In this embodiment, the first support 62 is slidably disposed on the first guide rail 61 via the first slider 64, and the second support 63 is fixed on the first guide rail 61. When the telescopic mechanism 5 moves, the first support 62 moves on the first guide rail 61 via the first slider 64, thereby satisfying the folding movement requirements of the first linkage unit 31 and the second linkage unit 32.

[0040] In one embodiment of this utility model, the conveying device further includes: a lifting plate 65, a second guide rail 66, a third support 67, and a fourth support 68.

[0041] In one embodiment of this utility model, to ensure the stability of floor lifting, two sets of the first linkage unit 31 and the second linkage unit 32 are respectively provided, that is, the floor lifting and transportation is achieved through four-point hoisting.
