Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a JP cabinet with a hoisting structure. Background Technology

[0002] JP switchgear is a type of integrated distribution transformer switchgear, mainly used in substations, factories, mining enterprises, large power plants, petrochemical enterprises, large steel mills, high-rise building power centers, reactive power compensation, metering, and power distribution. With the continuous deepening of rural power grid transformation, a large number of JP switchgear are being used in rural power lines and various distribution substations.

[0003] JP cabinets require lifting equipment for hoisting during handling or placement. Existing JP cabinets are usually equipped with fixed lifting mechanisms on the side of the cabinet or the top of the cover so that the lifting equipment can hook them.

[0004] However, this structure has the following technical drawbacks: First, the lifting mechanism cannot be retracted, causing the JP cabinet to occupy a significant amount of external space even when not in operation, increasing the space requirements for its placement. Second, the exposed lifting mechanism poses a collision risk to nearby personnel, creating a safety hazard. Third, the limited internal space of the cabinet, coupled with the fixed lifting mechanism, further compresses the operating area, affecting maintenance personnel's ability to access internal components and reducing maintenance efficiency. Furthermore, the long-term exposure of the lifting mechanism may accelerate structural corrosion or damage, affecting the equipment's lifespan. In summary, the design of the existing lifting mechanism needs improvement in terms of space utilization, safety protection, and ease of maintenance. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional background technology design and to provide a product that is easy to store, improves safety, and increases maintenance efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A JP cabinet with a lifting structure includes a cabinet body and an end cover fixed thereon. The end cover has rotatable lifting components on both sides. The end cover has a receiving cavity for accommodating the lifting components at a position away from the top. The lifting components include lifting lugs and a rotating shaft. The rotating shaft passes through one end of the lifting lug. The lifting lug has multiple transmission parts embedded in it. The receiving cavity has a limiting support part that abuts against and limits the lifting lug. The rotating shaft has damping mechanisms at both ends. The damping mechanisms contact the end cover. The lifting lug has a lifting hole, and an anti-detachment groove is provided on one side of the lifting hole.

[0008] Preferably, the lifting lug has a connecting part on the side away from the rotating shaft, the connecting part has a shaft hole, the transmission part is disposed on the inner wall of the shaft hole, and the two ends of the lifting lug have avoidance slopes and are located between the two connecting parts.

[0009] Preferably, the end cap is provided with opposing hinge seats, forming a receiving cavity between the hinge seats, the hinge seats are provided with mounting holes, and the end of the mounting holes is provided with countersunk holes.

[0010] Preferably, the rotating shaft is pivotally mounted in the mounting hole, the outer wall of the rotating shaft is provided with a transmission groove, and both ends of the rotating shaft are provided with internal threaded holes.

[0011] Preferably, the damping mechanism includes a fastening screw, a retaining ring, and a compression spring. The fastening screw is threaded into a threaded hole, the retaining ring is sleeved on the shank of the fastening screw, and the two ends of the compression spring abut against the retaining ring and the countersunk hole, respectively.

[0012] Preferably, the limiting support part is provided with a load-bearing surface. The limiting support part includes a first guide slope and a second guide slope. The first guide slope is used to guide the lifting lug to rotate out of the receiving cavity, and the second guide slope allows the lifting lug to enter the load-bearing surface and abut against it.

[0013] Beneficial effects:

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the coordinated operation of a rotatable lifting lug and a damping mechanism, enables stable switching between the lug's storage and working positions and allows it to hover at any angle, effectively reducing space occupation during non-operational periods. The contact structure between the limiting support and the lifting lug distributes the lifting load to the end cap, preventing the swivel bearing from deforming due to concentrated radial force. The anti-derailment design constrains the direction of sling displacement, improving the stability of the lifting process. The damping mechanism utilizes spring preload to provide controllable rotational resistance, ensuring the lug remains stable in any position. The avoidance inclined structure ensures interference-free rotation of the lug within the receiving cavity, optimizing smooth movement. The above structural design considers multiple aspects such as space utilization, operational safety, convenient storage, and equipment lifespan. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Reference example Figures 1 to 7 A JP cabinet with a hoisting structure includes a cabinet body 1 and an end cover 2 fixed thereon. The end cover 2 has rotatable hoisting components 3 on both sides. The end cover 2 has a receiving cavity 21 for accommodating the hoisting components 3 at a position away from the top. The hoisting components 3 include a lifting lug 31 and a rotating shaft 32. The rotating shaft 32 passes through one end of the lifting lug 31. The lifting lug 31 has multiple transmission parts 3141 and is embedded in the rotating shaft 32. The receiving cavity 21 has a limiting support part 22 and abuts against the lifting lug 31 for limiting. The rotating shaft 32 has damping mechanisms 4 at both ends. The damping mechanisms 4 contact the end cover 2. The lifting lug 31 has a hoisting hole 311. The hoisting hole 311 has an anti-detachment groove 312 on one side.

[0036] Through the coordinated operation of the rotatable lug 31 and the damping mechanism 4, the lug 31 can be stably switched between the storage position and the working position and can be suspended at any angle, effectively reducing the space occupied in the non-operational state. The contact structure between the limiting support part 22 and the lug 31 distributes the lifting load to the end cover 2, preventing the rotating shaft 32 from being deformed due to radial concentrated force. The anti-disengagement groove 312 design constrains the displacement direction of the sling, improving the stability of the lifting process. The damping mechanism 4 uses the spring preload to provide controllable rotational resistance, ensuring that the lug 31 remains stable in any position. The avoidance slope 315 structure ensures that the lug 31 rotates without interference in the receiving cavity 21, optimizing the smoothness of movement. The above structural design takes into account multiple requirements such as space utilization, operational safety, storage convenience and equipment service life. In addition, the receiving cavity 21 is located at the top away from the end cover 2 to prevent the lifting assembly 3 from being eroded by rainwater after storage, thereby extending its service life.

[0037] It is worth mentioning that the side of the lug 31 away from the rotating shaft 32 is provided with a connecting part 313, the connecting part 313 is provided with a shaft hole 314, the transmission part 3141 is provided on the inner wall of the shaft hole 314, and the two ends of the lug 31 are provided with avoidance slopes 315, which are located between the two connecting parts 313. The transmission part 3141 and the transmission groove 321 form an embedded fit structure to ensure that the rotating shaft 32 and the lug 31 are rigidly connected and there is no relative slippage when transmitting torque. This structure enables the rotating shaft 32 and the lug 31 to maintain synchronous rotation, and at the same time effectively transmits the axial force of the compression spring 43 to the lug 31, providing stable damping characteristics. The avoidance slope 315 design eliminates the motion interference of the lug 31 during the switching process between the storage position and the working position, ensuring a smooth and continuous rotation trajectory.

[0038] It is worth mentioning that the end cap 2 is provided with opposing hinge seats 23, and a receiving cavity 21 is formed between the hinge seats 23. The hinge seat 23 is provided with a mounting hole 24, and the end of the mounting hole 24 is provided with a countersunk hole 25. The countersunk hole 25 provides a receiving space for the compression spring 43 and prevents the compression spring 43 from being affected by the outside.

[0039] It is worth mentioning that the rotating shaft 32 is pivotally mounted on the mounting hole 24, the outer wall of the rotating shaft 32 is provided with a transmission groove 321, and both ends of the rotating shaft 32 are provided with internal threaded holes 322;

[0040] It is worth mentioning that the damping mechanism 4 includes a fastening screw 41, a retaining ring 42, and a compression spring 43. The fastening screw 41 is threaded into the threaded hole, the retaining ring 42 is sleeved on the shank of the fastening screw 41, and the two ends of the compression spring 43 abut against the retaining ring 42 and the countersunk hole 25, respectively. By rotating the fastening screw 41, the relative position of the retaining ring and the countersunk hole 25 is adjusted, thereby changing the preload of the compression spring 43 on the countersunk hole 25, and thus controlling the starting torque required for the rotation of the lifting lug 31. The change in the spring preload directly affects the rotation resistance of the lifting lug 31, optimizing the operating feel and positioning stability. The threaded connection structure also has a self-locking function to prevent loosening after adjustment.

[0041] It is worth mentioning that the limiting support part 22 is provided with a bearing surface 221. The limiting support part 22 includes a first guide slope 222 and a second guide slope 223. The first guide slope 222 is used to guide the lifting lug 31 to rotate out of the receiving cavity 21, and the second guide slope 223 causes the lifting lug 31 to enter the bearing surface 221 and abut against it.

[0042] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
