Description

Technical Field

[0001] This application relates to the field of power equipment technology, and more particularly to a lifting platform. Background Technology

[0002] With the continuous development of power systems, intermediate frequency switchgear (IFS), as a core device in power distribution networks, is widely used in various scenarios such as substations and industrial and mining enterprises, undertaking the important functions of power distribution and line protection. As a key component inside the IFS, the position and installation stability of the current transformer mounted on the busbar compartment partition directly affect the accuracy of power grid metering and the safety of operation.

[0003] Currently, the replacement and maintenance of current transformers mostly rely on manual lifting operations, which require staff to move, position and install the current transformers inside the switchgear.

[0004] However, due to the structural limitations of the central switch cabinet, the operating space inside the cabinet is small, especially the area around the busbar compartment partition, which is even more compact. It is difficult for manual operators to accurately control the alignment accuracy of the current transformer with the busbar compartment partition. A single operation often requires the cooperation of multiple workers, which is not only time-consuming, but may also affect the performance of the current transformer due to installation deviations.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] Please see Figures 1 to 3 This application provides a lifting platform, which includes: a base assembly 2, a pressure rod 3, and a support assembly 4;

[0043] The support component 4 is mounted on the base component 2 and is used to place the current transformer 1.

[0044] The pressure rod 3 is mounted on the base assembly 2. One end of the pressure rod 3 passes through the base assembly 2 and is movably connected to the support assembly 4. The pressure rod 3 is used to pull the support assembly 4 up or down.

[0045] The components of this embodiment are described in detail below:

[0046] The base assembly 2 connects to the support assembly 4 to provide installation support for the entire lifting platform.

[0047] The pressure rod 3 is mounted on the base assembly 2, with one end passing through the base assembly 2 and movably connected to the support assembly 4. It is mainly used to control the support assembly 4 to rise or fall through rotation, push and pull operations, thereby adjusting the height of the current transformer 1 placed on the support assembly 4.

[0048] The support assembly 4 is mounted on the base assembly 2 and is movably connected to the pressure rod 3. It is mainly used to place the current transformer 1 and to provide a stable installation platform for the current transformer 1 for maintenance and replacement.

[0049] Working principle:

[0050] In this embodiment, when it is necessary to install the current transformer 1 onto the busbar compartment partition, the current transformer 1 is first placed on the support assembly 4. Then, the base assembly 2 is moved to a suitable position, and then the pressure rod 3 is operated. Since one end of the pressure rod 3 passes through the base assembly 2 and is movably connected to the support assembly 4, when a force in a specific direction is applied to the pressure rod 3, such as pressing, the pressure rod 3 will pull the support assembly 4 upward. As the support assembly 4 slowly rises, the current transformer 1 placed on it also rises accordingly until the current transformer 1 accurately reaches the installation position on the busbar compartment partition. At this time, subsequent fixing and installation operations can be performed to complete the installation of the current transformer 1.

[0051] When it is necessary to remove the current transformer 1 from the busbar compartment partition, first move the base assembly 2 below the current transformer 1. Then, operate the pressure rod 3. Since one end of the pressure rod 3 passes through the base assembly 2 and is movably connected to the support assembly 4, when a force is applied to the pressure rod 3 in a specific direction, such as pressing, the pressure rod 3 will pull the support assembly 4 upward until the support assembly 4 rises to the bottom of the current transformer 1. Then, disassemble the current transformer 1 and the busbar compartment partition, separating them. Subsequently, apply the opposite force to the pressure rod 3, such as pulling. Since one end of the pressure rod 3 passes through the base assembly 2 and is movably connected to the support assembly 4, therefore... Under the action of the reverse force, the pressure rod 3 will pull the support assembly 4 down, and drive the current transformer 1 placed on the support assembly 4 to lower its height together. Further, the support assembly 4 continues to descend, and when the support assembly 4 descends, it will drive the current transformer 1 placed on it to lower its height together. Further, as the support assembly 4 continues to descend, the current transformer 1 gradually moves away from the busbar compartment partition. Finally, when the current transformer 1 descends to a suitable height, the operator moves the base assembly 2 to move the entire lifting platform out of the central cabinet, and then removes the current transformer 1 from the support assembly 4 for subsequent maintenance or replacement of the current transformer 1.

[0052] In practical applications, the current transformer 1 is supported by the support component 4, replacing manual lifting and avoiding positional deviations caused by unstable manual control. Next, the pressure rod 3 passes through the base component 2 and is movably connected to the support component 4, allowing workers to quickly install and remove the current transformer 1 within the confined space of the central control cabinet without the need for multiple people to work together. This structural design allows for operation by a single person, significantly reducing manpower input and greatly shortening the time required for each operation, improving maintenance efficiency, ensuring the accurate installation position of the current transformer 1, and thus guaranteeing the safety and stability of the power grid operation.

[0053] In an optional embodiment, the base assembly 2 includes a base component 5 and an outer column 6;

[0054] The bottom of the outer column 6 is fixed to the base component 5;

[0055] Support component 4 connects to the outer column 6;

[0056] One end of the pressure rod 3 passes through the outer column 6 and is movably connected to the support assembly 4.

[0057] This embodiment provides a specific implementation of the base assembly 2, which consists of a base component 5 and an outer column 6. When it is necessary to align or disassemble the current transformer 1 with the busbar compartment partition mounting position, the entire lifting platform is first adjusted to a suitable position by moving the base component 5. Next, the pressure rod 3 is operated. Since one end of the pressure rod 3 passes through the outer column 6 and forms a movable connection with the support assembly 4, and the outer column 6 acts as a guide carrier, it can provide a stable vertical movement trajectory for the pressure rod 3 and the support assembly 4. Therefore, when an external force is applied to the other end of the pressure rod 3, such as pressing or pulling, the pressure rod 3 will limit radial displacement through its cooperation with the outer column 6, and transmit the force only in the vertical direction to the support assembly 4. Then, under the action of the force, the support assembly 4 rises or falls stably along the outer column 6, and drives the current transformer 1 carried on the support assembly 4 to adjust its height synchronously, ultimately realizing the alignment or disassembly of the current transformer 1 with the busbar compartment partition mounting position.

[0058] In practical applications, the base component 5 provides a stable support foundation for the entire lifting platform, ensuring that the platform will not shake or shift due to external forces during the installation or removal of the current transformer 1, thus guaranteeing the stability and safety of the operation. The bottom of the outer column 6 is fixed to the base component 5, which not only enhances the overall structural strength of the lifting platform but also provides a reliable connection and support point for the pressure rod 3 and the support assembly 4. When the pressure rod 3 passes through the outer column 6 and is movably connected to the support assembly 4, the support assembly 4 can stably rise or fall with the pressure rod 3, realizing flexible adjustment of the height of the current transformer 1 and improving the efficiency of subsequent maintenance or replacement of the current transformer 1.

[0059] In an optional embodiment, the support component 4 includes a mounting platform 7 and an inner column 8;

[0060] The inner column 8 is installed inside the outer column 6;

[0061] Mounting platform 7 is fixed to the top of inner column 8;

[0062] The pressure rod 3 passes through the bottom of the outer column 6 and is movably connected to the inner column 8.

[0063] This embodiment provides a specific implementation of the support component 4, which consists of a mounting platform 7 and an inner column 8. When the pressure rod 3 is operated, since the pressure rod 3 passes through the outer column 6 and is movably connected to the bottom of the inner column 8, the force applied to the pressure rod 3 is transmitted to the inner column 8, causing the inner column 8 to move vertically up and down within the outer column 6. Since the mounting platform 7 is fixed to the top of the inner column 8, the raising and lowering of the inner column 8 will synchronously drive the mounting platform 7 and the current transformer 1 placed on the mounting platform 7 to move together, thereby realizing the installation or removal of the current transformer 1 from the busbar compartment partition mounting position.

[0064] In practical applications, the inner column 8 is set inside the outer column 6, forming a nested guide structure. This structure not only enables stable vertical lifting and lowering with the constraint of the outer column 6, but also efficiently transmits the driving force of the pressure rod 3 to the top through its movable connection with the pressure rod 3. Next, by fixing the mounting platform 7 to the top of the inner column 8, a stable bearing surface is provided for the current transformer 1, ensuring that the current transformer 1 is not prone to sliding or tilting when placed.

[0065] In an optional embodiment, the outer column 6 is provided with a sliding groove 9 and a triangular plate 10;

[0066] One end of the pressure rod 3 passes through the sliding groove 9 and connects to the end of the inner column 8;

[0067] The triangular plate 10 and the pressure rod 3 are movably connected by a pivot pin 20, and the pressure rod 3 is controlled to rotate around the pivot pin 20.

[0068] In this embodiment, a specific implementation of the outer column 6 is provided, in which the outer column 6 is provided with a sliding groove 9 and a triangular plate 10. One end of the pressure rod 3 passes through the sliding groove 9 and is connected to the end of the inner column 8. At the same time, the triangular plate 10 and the pressure rod 3 are movably connected by a pivot pin 20, so that the pressure rod 3 can be controlled to rotate around the pivot pin 20. When an external force is applied to the pressure rod 3, the pivot pin 20 becomes the fulcrum for the rotation of the pressure rod 3, and the pressure rod 3 performs lever motion with the pivot pin 20 as the fulcrum. At this time, the other end of the pressure rod 3 passing through the sliding groove 9 will swing up and down along a preset trajectory in the sliding groove 9. During the swinging process, the pressure rod 3, through the connection with the pivot pin 20 on the triangular plate 10, transmits the applied force to the end of the inner column 8, thereby driving the inner column 8 to make vertical lifting and lowering movements along the interior of the outer column 6, ultimately achieving precise lifting or lowering operation of the current transformer 1.

[0069] In practical applications, when workers operate in the confined space around the partition of the busbar compartment of the central switchgear, they only need to apply external force to the pressure rod 3. The inner column 8 can then be smoothly raised and lowered along the outer column 6 via the fulcrum of the triangular plate 10, avoiding the problem of force imbalance caused by limited space during manual lifting. The sliding groove 9 better constrains the swing range of the pressure rod 3. Combined with the fulcrum of the triangular plate 10, this ensures that the lifting trajectory of the inner column 8 and the current transformer 1 is stable and controllable. This easily achieves precise alignment of the current transformer 1 with the partition installation position, significantly reducing the manpower required for multi-person collaboration, shortening maintenance time, and reducing the risk of equipment performance being affected by installation deviations. This significantly improves the efficiency and safety of current transformer 1 installation and maintenance.

[0070] In an optional embodiment, the inner column 8 is provided with a bearing movable support 11;

[0071] The outer column 6 is provided with a slide rail 21 corresponding to the bearing moving bracket 11;

[0072] The inner column 8 is connected to the outer column 6 via the bearing moving bracket 11 and the slide rail 21.

[0073] In this embodiment, the inner column 8 is provided with a bearing movable support 11, and the outer column 6 is provided with a slide rail 21 adapted to the bearing movable support 11. The bearing movable support 11 is embedded in the slide rail 21, so that the inner column 8 and the outer column 6 are connected by this adaptation method. When the inner column 8 receives the traction of the pressure rod 3 to perform a lifting and lowering movement, the bearing movable support 11 on the inner column 8 will slide up and down along the trajectory of the slide rail 21 of the outer column 6. At the same time, the slide rail 21 provides a clear movement path and constraint for the bearing movable support 11, so that the inner column 8 can perform a stable and orderly vertical lifting and lowering movement relative to the outer column 6 along the direction defined by the slide rail 21.

[0074] In an optional embodiment, the bearing movable support 11 is provided with a slider 12, which is connected to the slide rail 21.

[0075] In this embodiment, a specific implementation of a bearing movable support 11 is provided, in which the bearing movable support 11 is provided with a slider 12. When the inner column 8 needs to move up and down relative to the outer column 6, the bearing movable support 11 transmits the force on the inner column 8 to the slider 12. Since the slider 12 is connected to the slide rail 21 of the outer column 6, under the drive of the force, the slider 12 will move linearly along the path preset by the slide rail 21, thereby driving the inner column 8 to achieve a stable and orderly vertical up and down movement relative to the outer column 6.

[0076] In an optional embodiment, the base component 5 includes a base support 13 and casters 14;

[0077] The top of the base bracket 13 is connected to the outer column 6;

[0078] The bottom of the base bracket 13 is connected to the caster 14.

[0079] This embodiment provides a specific implementation of the base component 5, which consists of a base bracket 13 and casters 14. The top of the base bracket 13 is connected to the outer column 6, bearing the load-bearing function of the entire lifting platform. It can evenly distribute and transfer the weight of components such as the outer column 6, inner column 8, mounting platform 7, and current transformer 1 to the bottom. The casters 14 are installed at the bottom of the base bracket 13. When the lifting platform needs to be moved, the applied external force, such as pushing the outer column 6, will be transmitted from the outer column 6 to the casters 14 through the base bracket 13. The casters 14 roll in the direction of the force under the driving force.

[0080] In practical applications, the top of the base bracket 13 is connected to the outer column 6, which can stably support the weight of components such as the outer column 6, inner column 8, mounting platform 7, and current transformer 1, ensuring the stability of the entire lifting platform structure during movement and use. The casters 14 have a small contact area with the ground, further reducing movement resistance, allowing workers to easily push the base component 5 in confined spaces and accurately adjust it to the required position.

[0081] In an optional embodiment, the base support 13 includes a first support 15, a second support 16, and a crossbeam 17;

[0082] The bottom of the outer column 6 is connected to the first bracket 15 and the second bracket 16;

[0083] The first support 15 faces the second support 16, and the first support 15 is connected to the second support 16 through the crossbeam 17.

[0084] In this embodiment, a specific implementation of the base support 13 is provided. In this implementation, the base support 13 is composed of a first support 15, a second support 16, and a crossbeam 17. The first support 15 and the second support 16 are arranged opposite to each other. The tops of the first support 15 and the second support 16 are connected to the bottom of the outer column 6, forming a symmetrically distributed support structure, which evenly transfers the weight borne by the outer column 6 to itself. One end of the crossbeam 17 is fixed to the first support 15, and the other end is fixed to the second support 16, so that the first support 15 and the second support 16 are connected to form an integral frame through the crossbeam 17.

[0085] In practical applications, the base bracket 13 strengthens the connection between the first bracket 15 and the second bracket 16 with the help of the crossbeam 17, avoiding relative swaying during load-bearing or movement. At the same time, the symmetrical support form, together with the crossbeam 17, further enhances the support stability of the top outer column 6, providing a solid foundation for the base assembly 2 of the entire lifting platform.

[0086] In an optional embodiment, the mounting platform 7 is provided with a plurality of limiting members 18 for fixing the current transformer 1.

[0087] In this embodiment, a specific implementation of the limiting member 18 is provided, in which the mounting platform 7 is provided with a plurality of limiting members 18. These limiting members 18 are distributed according to the shape characteristics of the bottom of the current transformer 1, collectively forming a suitable constraint space. When the current transformer 1 is placed on the mounting platform 7, the limiting members 18 contact the bottom housing of the current transformer 1 from different lateral directions, directly blocking and limiting its horizontal displacement. This prevents lateral sliding caused by vibrations from the movement of the lifting platform or external collisions, as well as forward and backward movement along the plane of the mounting platform 7. This ensures that during the lifting and lowering of the mounting platform 7 with the inner column 8, the current transformer 1 always maintains the preset installation posture, without shaking, tilting, or shifting, providing a stable foundation for subsequent installation or disassembly at the busbar compartment partition mounting position.

[0088] In an optional embodiment, the lever 3 is provided with a handle 19, which controls the rotation of the lever 3.

[0089] In this embodiment, a specific implementation of the pressure rod 3 is provided, in which the pressure rod 3 is provided with a handle 19. The handle 19 is fixed to the side of the pressure rod 3 away from the connecting end of the inner column 8, forming an integral structure with the pressure rod 3. When the operator holds the handle 19 and applies external force, the handle 19 directly transmits the force to the pressure rod 3, and uses the leverage effect of the force to drive the pressure rod 3 to rotate around the triangular plate 10.

[0090] Specifically, when the handle 19 is pressed, the lever 3 swings towards the outer column 6; when the handle 19 is pulled, the lever 3 swings away from the outer column 6. This structural design allows the operator to control the rotation angle and force of the lever 3 effortlessly through the handle 19 without directly contacting the main body of the lever 3, ensuring accurate and controllable lifting and lowering of the inner column 8.

[0091] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application.
