[0028] Example 1:

[0029] like Figures 1-3 As shown, this utility model provides a lifting device assembly 1, including: a lifting device body 10 and a counterweight 20. The lifting device body 10 has a first end and a second end in the length direction. The projection of the first end in the height direction is located inside the object to be lifted, and the projection of the second end in the height direction is spaced apart from the object to be lifted. The bottom of the lifting device body 10 is provided with a plurality of lifting parts 111, which are adapted to cooperate with the object to be lifted. At least one lifting part 111 is located at the first end. The top of the lifting device body 10 is provided with a plurality of connecting parts 112, which are adapted to cooperate with the lifting rope 2. The plurality of connecting parts 112 are respectively located between the first end and the second end. The counterweight 20 is movably connected to the lifting device body 10 and is adapted to move in the length direction.

[0030] In some embodiments, the lifting device body 10 has a first end and a second end in the length direction, wherein the projection of the first end in the height direction is located inside the equipment 3 to be lifted, while the projection of the second end in the height direction is spaced apart from the equipment 3 to be lifted.

[0031] The bottom of the lifting device body 10 is provided with multiple lifting parts 111, which are used to cooperate with the equipment 3 to be lifted. At least one lifting part 111 is located at the first end of the lifting device body 10. The top of the lifting device body 10 is provided with multiple connecting parts 112, which are used to cooperate with the lifting rope 2 to ensure that the lifting device can be lifted by a crane or other equipment. The multiple connecting parts 112 are distributed at intervals between the first end and the second end.

[0032] The counterweight 20 is movably connected to the lifting device body 10, and the counterweight 20 is adapted to move in the length direction, that is, the counterweight 20 can move between the first end and the second end to balance the weight distribution of the entire lifting device assembly 1 and the equipment 3 to be lifted, and ensure stability during the lifting process.

[0033] It is understandable that there are usually obstructions in the air at the edge of the factory building, such as air ducts or cable conduits. However, in order to maximize the use of the factory floor space, production equipment is usually also set up at the edge of the factory building (below the obstructions). However, when hoisting these production equipment, the obstructions will block the hoisting lines, making it impossible to carry out the hoisting work normally. Usually, the production equipment is hoisted to a certain position and then manually or using a forklift to install the production equipment to the designated position, which is time-consuming and labor-intensive.

[0034] When using the lifting device assembly 1 of this application, firstly, the first end of the lifting device body 10 is placed above the equipment 3 to be lifted. Then, the lifting part 111 is engaged with the lifting point of the equipment 3 to be lifted to fix the lifting device assembly 1 and the equipment 3 to be lifted. Next, the lifting rope 2 is connected to the connecting part 112 of the lifting device body 10. Finally, the crane equipment can be used to lift the equipment 3 to be lifted.

[0035] It is worth mentioning that during hoisting, the first end of the lifting device body 10 can be inserted under the obstruction 4. Thus, the lifting device assembly 1 of this application can be used to hoist the equipment 3 to be hoisted to the designated position in one go, avoiding the need to move the equipment 3 to be hoisted again by manpower or forklifts, which facilitates the installation of the equipment 3 to be hoisted.

[0036] Therefore, by designing the lifting device body 10 with a first end and a second end in specific positions, the lifting device body 10 can avoid obstructions 4 (such as exhaust pipes or conduits) in the factory during lifting, thereby improving the installation efficiency of the equipment 3 to be lifted.

[0037] It should be noted that since multiple connecting parts 112 are located between the first end and the second end respectively, that is, multiple connecting parts 112 are not provided at the first end, the equipment 3 to be lifted will be in an inclined state during lifting. This application compensates for the center of gravity shift caused by the asymmetry of the lifting points by moving the counterweight block 20, so as to make the lifting process more stable and smooth.

[0038] According to the lifting device assembly 1 of this utility model, the lifting device assembly 1 of this application can be applied in factories with complex layouts to effectively carry out lifting operations on the equipment 3 to be lifted. That is, it can flexibly deal with obstructions 4 in different positions in the factory. It can effectively arrange and install equipment under the obstructions 4 without changing the existing layout of the factory, making the most of the factory space. Moreover, by configuring the movable counterweight 20, the stability of the equipment 3 to be lifted can be ensured during the lifting process, reducing the risk of tilting or overturning of the equipment 3 to be lifted, thereby improving the safety of the lifting operation.

[0039] Example 2:

[0040] Based on Embodiment 1, this embodiment further includes a lifting assembly: a drive mechanism connected to the lifting body 10, the drive mechanism having a drive section connected to a counterweight 20, and the drive mechanism operating to drive the counterweight 20 to move in the length direction.

[0041] In some embodiments, the drive mechanism is connected to the lifting body 10, and the drive mechanism is equipped with a drive unit that is directly connected to the counterweight 20. When the drive mechanism is working, the drive unit can drive the counterweight 20 to move in the length direction of the lifting body 10. That is, this application can precisely adjust the position of the counterweight 20 by controlling the drive mechanism, thereby optimizing the center of gravity distribution of the entire lifting system (the lifting system includes the equipment to be lifted 3 and the lifting assembly 1).

[0042] Understandably, the drive mechanism allows operators to dynamically adjust the position of the counterweight 20 according to actual lifting requirements. For example, when facing asymmetrical loads or requiring particularly precise balancing, the drive mechanism can be used to quickly and accurately adjust the position of the counterweight 20, ensuring stability during the lifting process.

[0043] According to some embodiments of the present invention, the driving mechanism includes: a rotating rod 31, a sprocket 32, and a chain 33. The rotating rod 31 is configured as two rods rotatably connected to the lifting body 10, with the two rotating rods 31 located at the first end and the second end, respectively. The sprocket 32 ​​is configured as two rods, each corresponding to and coaxially connected to the two rotating rods 31. The two ends of the chain 33 are respectively engaged with the two sprockets 32, and the chain 33 is configured as a driving part and connected to the counterweight 20.

[0044] Understandably, the rotation of the rotating rod 31 drives the sprocket 32 ​​to rotate, which in turn causes the chain 33 to produce linear motion. This linear motion of the chain 33 can be directly used to push or pull the counterweight 20, thus moving the counterweight 20 along its length. Of course, since the chain 33 is directly connected to the counterweight 20, the position of the counterweight 20 can be precisely adjusted by controlling the rotation of the rotating rod 31, providing not only reliable power transmission but also ensuring high positional accuracy.

[0045] It is worth mentioning that, according to actual needs, operators can quickly and accurately change the position of the counterweight 20 by adjusting the rotation speed and direction of the rotating rod 31, so as to meet the needs of different lifting tasks and enable the lifting assembly 1 to cope with more types and more complex lifting scenarios.

[0046] Example 3:

[0047] Based on Embodiment 2, this embodiment further includes a drive motor 34, which is connected to the lifting body 10. The drive motor 34 has a rotatable output shaft, which is connected to one of the rotating rods 31. The drive motor 34 is adapted to drive the rotating rod 31 to rotate.

[0048] In some embodiments, the drive motor 34 serves as a power source, converting electrical energy into mechanical energy through its output shaft, thereby driving the rotating rod 31 to rotate. Specifically, the output shaft of the drive motor 34 is connected to one of the rotating rods 31, which then transmits power to the other rotating rod 31 through a sprocket 32 ​​and chain 33 system, ensuring that the two rotating rods 31 can work synchronously, thereby ensuring that the chain 33 moves smoothly and that the position of the counterweight 20 can be accurately positioned.

[0049] Therefore, by introducing the drive motor 34, the position adjustment of the counterweight 20 is automated. Operators can easily adjust the position of the counterweight 20 through the control system without manual intervention, which improves work efficiency and reduces labor costs. Moreover, the drive motor 34 can control the rotation angle and speed very precisely, so that the position adjustment of the counterweight 20 can achieve a very high precision.

[0050] Of course, using a drive motor 34 instead of manual adjustment increases the stability and reliability of the system. Furthermore, the modern drive motor 34 is equipped with a feedback mechanism (such as an encoder) that can monitor and adjust its operating status in real time, ensuring the lifting system is always in optimal working condition.

[0051] According to some embodiments of the present invention, the rotating rod 31 extends in the width direction, and a worm gear is coaxially arranged on the rotating rod 31. The output shaft of the drive motor 34 extends in the height direction, and a worm gear is coaxially arranged on the output shaft, with the worm gear meshing with the worm gear.

[0052] In some embodiments, the above-described arrangement allows the projection of the drive motor 34 in the height direction to be located within the lifting device body 10, thereby preventing the drive motor 34 from protruding from the lifting device body 10 in the width direction, making the lifting device assembly 1 more convenient to store and transport.

[0053] When the drive motor 34 is working, it can cause the output shaft to rotate. The rotation of the output shaft can drive the worm gear to rotate. The rotation of the worm gear can drive the turbine to rotate. The rotation of the turbine can drive the coaxially arranged rotating rod 31 to rotate. The rotation of the rotating rod 31 can drive the coaxially arranged sprocket 32 ​​to rotate, thereby realizing the movement of the drive chain 33.

[0054] Example 4:

[0055] Based on Embodiment 1, the lifting device body 10 includes: connecting plates 11 and connecting rods. The connecting plates 11 are configured as two extending in the length direction and spaced apart from each other in the width direction. The connecting rods are configured as multiple extending in the width direction and spaced apart from each other in the length direction, and the two ends of the multiple connecting rods are respectively connected to the two connecting plates 11.

[0056] In some embodiments, by using two spaced-apart connecting plates 11 and connecting them together with multiple connecting rods, a robust frame structure is formed, giving the spreader body 10 sufficient strength to support the lifting operation. This allows the spreader body 10 to withstand greater loads during lifting without deformation or damage, thereby improving operational safety. The lifting portion 111 and the connecting portion 112 are distributed on the two connecting plates 11, which helps to disperse the force, reduce local stress concentration, and improve overall safety and reliability.

[0057] According to some embodiments of the present invention, the multiple connecting rods each include: multiple first connecting rods 12 and multiple second connecting rods 13. The multiple first connecting rods 12 are spaced apart from each other in the length direction, and the two ends of the multiple first connecting rods 12 are respectively connected to the top of two connecting plates 11. The multiple second connecting rods 13 are spaced apart from each other in the length direction, and the two ends of the multiple second connecting rods 13 are respectively connected to the bottom of two connecting plates 11. The multiple first connecting rods 12 and multiple second connecting rods 13 are spaced apart from each other in the height direction and form an active space between them. The counterweight 20 is movably disposed in the active space.

[0058] In some embodiments, by dividing the multiple connecting rods into upper and lower layers (i.e., a first connecting rod layer and a second connecting rod layer, the first connecting rod layer including multiple first connecting rods 12, the multiple first connecting rods 12 being spaced apart from each other in the length direction and having their ends connected to the top of two connecting plates 11 respectively, and the second connecting rod layer including multiple second connecting rods 13, the multiple second connecting rods 13 being spaced apart from each other in the length direction and having their ends connected to the bottom of two connecting plates 11 respectively), it helps to disperse various forces generated during the hoisting process, avoid structural damage or deformation caused by excessive force on a single point, and enhance the overall rigidity and stability of the lifting device body 10.

[0059] A movable space is formed between the first link 12 and the second link 13, which allows the counterweight 20 to move freely in the length direction. The drive mechanism can drive the counterweight 20 to move within the movable space through the chain 33 or other mechanical devices, thereby achieving precise center of gravity adjustment.

[0060] According to some embodiments of this utility model, two connecting plates 11 are provided with opposing sliding grooves on one side facing each other, and the counterweight 20 is provided with sliders at both ends in the width direction, and the sliders are slidably received in the corresponding sliding grooves. The sliding grooves extend in the length direction.

[0061] In some embodiments, the counterweight 20 is connected to two connecting plates 11 via sliders at both ends, ensuring the structural stability of the lifting device assembly 1. Simultaneously, the inner peripheral wall of the slide groove can restrict the outer peripheral wall of the slider, allowing the slider to move stably along the extension direction of the slide groove, thereby enabling the counterweight 20 to move stably along its length.

[0062] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
