In order to meet the needs of installation, transportation and other operations, it is often necessary to evenly distribute four lifting points on the entire cabinet. During the lifting process, due to the inconsistency of the appearance and dimensions, different specifications and lengths of lifting straps are required. In addition, due to the eccentric center of gravity, it is easy to cause the power cabinet to shift, resulting in safety accidents.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The core of the utility model is to provide a lifting device, which can ensure the reliability and safety of the power cabinet during lifting, save time and effort, do not require other auxiliary equipment, and do not need to make adjustments during the lifting process, thereby improving the efficiency of the lifting operation.

[0027] The lifting device provided by the utility model is used for lifting operations of the power cabinet 4. Several groups of lifting devices are arranged on the power cabinet 4 for lifting operations, specifically arranged on the circumference or center position of the power cabinet 4, and can be flexibly arranged in combination with the actual design of the power cabinet.

[0028] by Figure 2 For example, four sets of lifting devices are arranged at the four corners of the power cabinet 4. In this case, the power cabinet 4 is a square structure. Figure 2 This is just an illustration and is not limited to this method.

[0029] Please refer to Figure 1 , Figure 2 The hoisting part 1 is connected to the lifting equipment, and one end of the cable 2 is connected to the hoisting part 1, and the other end is wound around the recovery mechanism 3. The recovery mechanism 3 is fixed in the power cabinet 4. When performing the hoisting operation, the hoisting operation of the entire power cabinet 4 can be realized by connecting the hoisting equipment to the hoisting part 1.

[0030] The specific form of the hoisting portion 1 is not limited, and can be annular, arc-shaped or other, and can be flexibly changed in combination with the hoisting type of the specific hoisting equipment.

[0031] The cable 2 is wound around the recovery mechanism 3, and the recovery mechanism 3 can be rotated to adjust the length of the cable 2 extending out of the power cabinet 4. Specifically, in the initial operating state, the cable 2 is arranged in the power cabinet 4; when a lifting operation is required, the cable 2 is extended out of the top of the power cabinet 4 through the rotation of the recovery mechanism 3 to drive the lifting of the lifting part 1; when the lifting operation is completed, the recovery mechanism 3 rotates to recover the cable 2, and the cable 2 remains in its original state wound around the recovery mechanism 3, and the lifting part 1 is at the top of the power cabinet 4.

[0032] The limiting mechanism can limit the rotation of the recovery mechanism 3 according to the actual operating conditions. Specifically, when the center of gravity offset of the power cabinet 4 matches the extended length of the cable 2, that is, the extended length of the cable 2 can compensate for the center of gravity offset. At this time, the limiting mechanism operates to limit the rotation of the recovery mechanism 3. At this time, the extended length of the cable 2 no longer changes, and the lifting operation can be carried out directly, thereby ensuring the reliability and safety of the lifting operation and improving the efficiency of the lifting operation.

[0033] It should be noted that the center of gravity offset of the power cabinet 4 is also obtained by manual calculation or with the help of calculation software. After obtaining the type, structure and size of the power cabinet 4, the center of gravity offset of the power cabinet 4 can be known.

[0034] Specifically, the weight of the components in each area of ​​the power cabinet 4 is multiplied by the center of gravity coordinates of the area, and then the results of all areas are added together to obtain the overall center of gravity coordinates of the entire power cabinet 4, so as to further calculate the center of gravity offset.

[0035] The above is only one calculation method and is not limited thereto. It can be combined with imaging, scanning and other technologies.

[0036] Optionally, the limiting mechanism can be implemented in a variety of ways, such as a telescopic member, which blocks the recovery mechanism 3 from rotating when extended and rotates freely when retracted. It can be a plurality of nodes on the cable 2, and when the cable 2 is extended to a length that meets the requirements, the node is stuck on the inner wall of the top of the power cabinet 4, and the recovery mechanism 3 no longer rotates.

[0037] Optionally, the cable 2 may be made of a material with certain strength and toughness, which can be flexibly selected based on actual needs.

[0038] In this embodiment, the length of the cable 2 extending out of the power cabinet 4 can be obtained by a variety of measurement methods without limitation.

The length of the cable 2 extending from the power cabinet 4 can be adjusted by rotating the recovery mechanism, that is, the height of the lifting part 1 is increased; the limiting mechanism is used to limit the rotation of the recovery mechanism 3. When the extended length of the cable 2 matches the center of gravity offset of the power cabinet 4, the limiting mechanism operates to limit the operation of the recovery mechanism. At this time, the recovery mechanism 3 no longer rotates, and the extended length of the cable 2 no longer increases. At this time, the extended length of the cable 2 can compensate for the center of gravity offset of the power cabinet 4, meeting the conditions for reliable and stable lifting. At this time, when the power cabinet is lifted by the lifting equipment, better operation safety and stability can be guaranteed, without the need for other auxiliary equipment, and no adjustment is required during the lifting process, thereby improving the lifting operation efficiency.

The control mechanism can control the operation of the limiting mechanism according to the calculated center of gravity offset to achieve accurate and effective adjustment of the length of the cable 2 extending out of the power cabinet 4.

[0042] On the basis of any of the above embodiments, an elastic connector is provided between the cable 2 and the recovery mechanism 3 , and when the cable 2 extends out of the power cabinet 4 , the elastic connector is stretched.

The reliable connection here means that there will be no breakage at the connection point between the two, and the entire mechanism operates reliably. When the recovery mechanism 3 rotates to extend the cable 2 out of the power cabinet 4, the elastic connector is in an extended state; when the extended cable 2 needs to be recovered, the elasticity of the elastic connector is used to achieve the effect of automatic recovery or recovery in cooperation with the recovery mechanism 3, saving time and effort and improving operation efficiency.

[0047] In this embodiment, the hand wheel is rotated to drive the rotation of the rotating wheel, which further drives the adjustment of the length of the cable 2 wound on the rotating wheel. The hand wheel can be rotated manually, and the extended length of the cable 2 can also be directly known by the number of rotations of the hand wheel.

[0048] The handwheel can be combined with common structural designs to save effort while ensuring reliable operation.

The rotation of the wheel drives the cable 2 wound thereon to extend out of the power cabinet 4 to adjust the length, so as to compensate for the offset of the center of gravity of the power cabinet 4.
