[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] In the description of the present invention, it is necessary to understand that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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.

[0039] In order to solve the problem that the traditional transportation method mainly relies on manual labor and has obvious limitations when dealing with heavy materials, the commonly used method is to use mechanical transfer and carry out two-layer lifting on the transport vehicle. In the narrow construction site environment, the mechanical method is often difficult to use, and usually requires the cooperation of multiple people, which increases the labor cost. The mechanical transfer process requires multiple loading and unloading, which is cumbersome and inefficient, and is prone to safety accidents.

[0040] In view of this, the present invention provides a movable device that is easy to install and disassemble to lift and move heavy objects, see the attached Figure 1 and 2 , including: a wheel frame, an operating rod 12 and a hook hanging piece; two wheels 16 are correspondingly installed on both sides of the bottom of the wheel frame, and the operating rod 12 is detachably connected to the top of the wheel frame; the hook hanging piece is detachably installed at one end of the operating rod 12, and the distance L1 between the hook hanging piece and the wheel frame is smaller than the distance L2 between the wheel frame and the other end of the operating rod 12.

[0041] The above embodiment uses the lever principle and the design of the operating rod, wheel frame and hook hanging member, so that the operator can lift heavier objects with less force, which is suitable for occasions where heavy objects need to be frequently moved and lifted in a small environment.

[0042] In one embodiment of the present invention, the wheel frame includes: a wheel axle 15, a support frame and a support frame sleeve 17; the two ends of the wheel axle 15 are rotatably connected to the two wheels 16 through two sets of bearings, and the wheels are connected to the wheel axle 15 through bearing nuts 19; the bottom of the support frame is connected to the wheel axle 15; the support frame sleeve 17 is fixed to the top of the support frame, and is sleeved on the operating rod 12, and is detachably connected to the operating rod 12 through a connecting piece.

[0043] In this embodiment, the wheel axle 15, the support frame and the support frame sleeve 17 are all detachable, which is convenient for assembly or disassembly. In different usage scenarios, it is convenient to replace the operating rod 12 of different lengths, which is easy to use.

[0044] In another embodiment of the present invention, the support frame includes: a support rod 14 and a side support 13; the support rod 14 serves as a main support, a first end of which is connected to the support frame sleeve 17, and a second end of which is connected to the wheel axle 15; the side support 13 serves as an auxiliary support, connected to both sides of the support rod 14, a first end of which is staggered with the first end of the support rod 14 and connected to the support frame sleeve 17, and a second end of which is staggered with the second end of the support rod 14 and connected to the wheel axle 15.

[0045] In a specific embodiment of the present invention, the support rod 14, the side support 13, the wheel axle 15 and the support frame sleeve 17 are welded and fixed to form a whole, thereby increasing the overall strength of the device.

[0046] Advantageously, based on the above-mentioned embodiment of the present invention, the side support 13 is two groups of mirror-arranged V-shaped rods, the middle part of the V-shaped rod is welded to the support rod 14, the first end of the V-shaped rod is welded to the support frame sleeve 17, and the second end thereof is welded to the wheel axle 15.

[0047] The side support 13 is two sets of mirror-image V-shaped rods, which can improve the stability of the structure. The V-shaped rod design can effectively disperse the force applied to the operating rod through its unique geometric shape. Since the V-shaped rod can effectively disperse stress and reduce the load of a single component, the risk of wear is reduced. This design enhances the stability of the entire support frame and reduces deformation and damage caused by uneven force. It helps to extend the overall service life of the device and reduce maintenance and replacement costs. At the same time, it increases the anti-roll capability. The arrangement of the V-shaped rod enables the device to better resist roll when subjected to lateral force. The V-shaped rod design increases the load-bearing capacity of the device, allowing it to withstand heavier loads.

[0048] The connecting member of the present invention can be a high-strength screw connection pair, that is, a high-strength screw 11, one end of which is connected to the support frame sleeve 17 and passes through the support frame sleeve 17 to abut or separate from the operating rod 12. During installation, by tightening the high-strength screw, one end of the high-strength screw enters the support frame sleeve 17 and abuts against the operating rod 12. During disassembly, the high-strength screw is loosened and one end of the high-strength screw is separated from the operating rod 12, which is convenient for installation and disassembly.

[0049] In other embodiments of the present invention, the hook hanging member includes: a hook 18, a hook connecting sleeve and a hook connecting member, the hook 18, the hook connecting sleeve connecting the hook 18 and sleeved on one end of the operating rod 12; the hook connecting member is also a high-strength screw connecting pair, one end of which is detachably connected to the hook connecting sleeve and passes through the hook connecting sleeve to abut or separate from the operating rod 12. The high-strength screw connecting pair is also a high-strength screw 11, and the method of installing and removing the hook 18 is the same as the connection method of the support frame sleeve 17 and the operating rod 12.

[0050] In other embodiments of the present invention, the other end of the operating rod 12 is detachably connected to an armrest 10, and the armrest 10 is arranged vertically downward relative to the operating rod, and its height from one end close to the operating rod 12 to the other end is L3, and the height of the support frame is L4.

[0051] Based on the above embodiments of the present invention, the armrest 10 has an armrest connecting sleeve, which is fixed to the armrest 10, and the armrest connecting sleeve is sleeved on the other end of the operating rod 12, and is abutted against or separated from the operating rod 12 through an armrest connecting piece.

[0052] The handrail connecting piece can also be a high-strength screw 11, and the method of installing and removing the handrail 10 is the same as the connection method of the support frame sleeve 17 and the operating rod 12.

[0053] See attached Figure 2 The structural dimension ratio of the present invention can be: 3L1≤L2, 2L3≤L4, wherein L1 is the distance between the hook and the wheel frame, L2 is the distance between the wheel frame and the other end of the operating rod 12; L3 is the height of the handrail 10 from one end close to the operating rod 12 to the other end, and L4 is the height of the support frame.

[0054] The present invention ensures that the distance between the hook and the wheel frame is small, while the distance at the other end of the operating rod is large by setting the ratio of 3L1≤L2 and 2L3≤L4. This design uses the principle of leverage, allowing the operator to lift heavier objects with less force, thereby improving work efficiency. The height L4 of the support frame is greater than twice the height L3 of the handrail, that is, 2L3≤L4. This design enhances the stability of the entire device. When lifting heavy objects, the device can better resist rollover and deformation, ensuring the safety of operation.

[0055] The present invention also optimizes the distribution of the lever arm by reasonably designing the ratio of L1 and L2. The shorter L1 and the longer L2 make the operating lever more labor-saving when in use, reduce the labor intensity of the operator, and improve the ability to lift heavy objects.

[0056] The structural size ratio design of the present invention enables the device to withstand greater loads when lifting heavy objects. By optimizing the size and positional relationship of each component, the overall load-bearing capacity of the device is improved, making it suitable for handling heavier objects.

[0057] In a specific embodiment of the present invention, the diameters of the armrest connecting sleeve, the support frame sleeve, and the hook connecting sleeve can all be 50 mm, the diameter of the high-strength screw rod can be 16 mm, and the diameter of the operating rod can be 48 mm.

[0058] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] During installation, assemble the wheel frame, insert both ends of the wheel axle 15 into two groups of bearings respectively, install the bearing nuts 19 to ensure that the wheels 16 can rotate freely. Fix the support frame on the wheel axle 15 to ensure the stability of the support frame. Fix the support frame sleeve 17 on the top of the support frame so that it can sleeve the operating rod 12.

[0060] If the wheel axle 15 and the support frame are connected by welding, the wheels 16 can be directly installed at both ends of the wheel axle 15.

[0061] Install the operating rod, insert one end of the operating rod 12 into the support frame sleeve 17 and fix it through the high-strength screw rod connecting副将. Ensure that the operating rod 12 can be stably supported on the wheel frame.

[0062] Install the hook member, sleeve one end of the hook member on the other end of the operating rod 12 and fix it through the high-strength screw rod connecting副将. Ensure that the hook member can be firmly installed on the operating rod 12.

[0063] Adjust the distance to ensure that the distance L1 between the hook member and the wheel frame is less than the distance L2 between the wheel frame and the other end of the operating rod 12. This design enables the hook member to provide a greater lever arm when lifting heavy objects, thereby reducing the labor intensity of the operator.

[0064] During use, when the device needs to be moved, the wheels 16 can be pushed to make the entire device roll on the ground. When lifting heavy objects, hang the hook member on the heavy object to be lifted. Apply a downward pressure through the operating rod 12 and use the lever principle to lift the heavy object. Due to the design of L1 < L2, the operator can lift heavier objects with less force.

[0065] When the device needs to be disassembled, just loosen the high-strength screw connection pair to easily disassemble the components.

[0066] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0067] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
