Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] Embodiments of this utility model: such as Figure 1 As shown, a portable equipment hoisting device includes a counterweight box 1, with a wheel 2 equipped with brakes at the bottom of the counterweight box 1. A platform 3 is provided on the upper side of one side of the counterweight box 1, with the top surface of the platform 3 being flush with the top surface of the counterweight box 1. A rotating rod assembly is provided on the platform 3, and a telescopic hoisting rod assembly is rotatably mounted on the top of the rotating rod assembly. A pull rope 4 is connected to the end of the telescopic hoisting rod assembly. A lifting component is provided on the side wall of the rotating rod assembly, and the telescopic end of the lifting component is connected to the telescopic hoisting rod assembly.

[0018] The counterweight box 1 is equipped with braked wheels 2 at its bottom, allowing it to be moved to the desired working position. Once in position, the brakes on the braked wheels 2 are depressed, preventing further movement. Sandbags, stones, or other heavy objects can be placed inside the counterweight box 1 as needed to increase the weight of the lifting device chassis. It should be noted that the braked wheels 2 are commercially available products and can be purchased directly. The braking principle of the braked wheels 2 will not be elaborated in this embodiment.

[0019] The pull rope 4 can be easily moved above the equipment or accessories to be lifted (hereinafter collectively referred to as the heavy object) by means of the rotating rod assembly and the telescopic boom assembly. After the pull rope 4 is tied together with the heavy object to be lifted, the telescopic boom assembly can be lifted by means of the lifting assembly, thereby lifting the heavy object.

[0020] Specifically, a cover 5 is installed on the top of the counterweight box 1, and one side of the cover 5 is hinged to the counterweight box 1 via a hinge 6. The other side of the cover 5 is connected to the counterweight box 1 via a locking assembly 28 to prevent the cover 5 from being opened accidentally. Two diagonal support rods 27 are also fixedly installed on the side wall of the counterweight box 1, and the upper ends of the two diagonal support rods 27 are fixedly connected to the bottom surface of the platform 3. The diagonal support rods 27 can improve the load-bearing capacity of the platform 3 and prevent the platform 3 from collapsing.

[0021] Furthermore, the rotating rod assembly includes a base 7, an outer sleeve 8, and a rotating rod 9. The lower end of the outer sleeve 8 is fixedly connected to the base 7, and the four corners of the base 7 are fixedly connected to the platform 3 through bolt assemblies 10. The lower end of the rotating rod 9 is inserted into and rotatably connected to the outer sleeve 8, and two handles 13 are fixedly provided on the outer wall of the rotating rod 9.

[0022] The rotating rod 9 can be rotated by two handles 13, which allows the weight to move around the rotating rod 9.

[0023] Preferably, a ball 11 is provided inside the outer sleeve 8, the bottom surface of the rotating rod 9 abuts against the ball 11, and a rotating bearing 12 is provided at the upper end inside the outer sleeve 8, with the rotating rod 9 and the inner ring of the rotating bearing 12 being interference-fitted.

[0024] The inner ring diameter of the rotating bearing 12 is slightly smaller than the inner diameter of the outer sleeve 8. The upper end of the outer sleeve 8 has a bearing mounting groove for installing the rotating bearing 12, and the outer diameter of the outer sleeve 8 is larger than the outer ring diameter of the rotating bearing 12. The inner diameter of the outer sleeve 8 is slightly larger than the diameter of the rotating rod 9, ensuring that the rotating rod 9 can rotate smoothly within the outer sleeve 8 without tilting. The ball 11 prevents the bottom surface of the rotating rod 9 from directly contacting the base 7, reducing the rotational friction of the rotating rod 9.

[0025] Furthermore, a mounting base 14 is formed at the top of the rotating rod 9. The telescopic rod assembly includes an outer rod 15 and an inner rod 16. The outer rod 15 has a cylindrical structure, and one end of the outer rod 15 is rotatably connected to the mounting base 14 via a first rotating shaft 20. One end of the inner rod 16 is inserted into and slidably connected to the other end of the outer rod 15. Multiple sets of first limiting holes 17 are provided on the outer rod 15. A second limiting hole (not shown in the figure) is provided at the end of the inner rod 16 located inside the outer rod 15. The second limiting hole is connected to one set of first limiting holes 17 via bolts 19. A hook 26 is provided at the end of the inner rod 16, and the upper end of the pull rope 4 is connected to the hook 26.

[0026] The telescopic boom assembly with this structural design allows the position of the inner boom 16 to be adjusted as needed, thereby changing the total length of the outer boom 15 and the inner boom 16, making the product more flexible.

[0027] Furthermore, the lifting assembly includes a support arm 21 and a hydraulic jack 22. The support arm 21 is fixed to the outer wall of the outer sleeve 8. The lower end of the hydraulic jack 22 is rotatably mounted on the support arm 21 via a second rotating shaft 23. The hydraulic rod 24 of the hydraulic jack 22 is rotatably connected to the outer lifting rod 15 via a third rotating shaft 25.

[0028] The lifting assembly supports the telescopic boom assembly. In this embodiment, the lifting assembly uses a hydraulic jack 22, which is manually operated and has a jack handle 18. It should be noted that, depending on the requirements, the hydraulic jack 22 can be replaced with an electric hydraulic cylinder or an electric telescopic boom.

[0029] The working principle of this utility model is as follows: When in use, release the brake on the braked wheel 2, push the counterweight box 1 to the appropriate working position, and then step on the brake on the braked wheel 2 to prevent the counterweight box 1 from moving. Then, according to the weight of the object to be lifted, fill the counterweight box 1 with sandbags or stones, and after filling, close the cover 5 and lock the cover 5 with the locking assembly 28.

[0030] Then remove bolt 19, adjust the position of the inner lifting rod 16, and then reinstall bolt 19. Next, manually operate handle 13 to move the lower end of the pull rope 4 above the object to be lifted. Tie the lower end of the pull rope 4 to the object. Then, operate the hydraulic jack 22 using jack handle 18 to raise the hydraulic rod 24, which in turn pushes the outer lifting rod 15, lifting the object. Finally, move the object to an open area and lower it.

[0031] When encountering a particularly narrow space, if the counterweight box 1 cannot be entered, the bolt assembly 10 can be removed to fix the rotating rod assembly to the ground, which can also achieve the lifting of heavy objects.

[0032] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
