Description

Technical Field

[0001] This invention relates to the field of high-voltage switchgear, and in particular to a mobile high-voltage switchgear installation and commissioning platform. Background Technology

[0002] High-voltage switchgear refers to equipment used in power systems for switching, controlling, or protecting power during generation, transmission, distribution, energy conversion, and consumption. It is commonly used in power engineering and is also frequently prone to malfunctions. When installing or moving it, cranes can only lift the equipment to the doorway. The equipment is very heavy, and there are usually several steps between the outdoor and indoor areas, making it impossible to directly place the equipment on a forklift or rollers. Furthermore, the equipment cannot be placed on the ground; it generally requires a foundation.

[0003] Currently, the common practice is to use sleepers to create a small platform at the outdoor entrance, raising it to a height similar to a few steps or the foundation inside. Two channel steel beams are then laid on top, with one end resting on the sleepers and the other end resting on the interior or foundation, with the grooves of the channel steel facing upwards. The equipment is then carefully hoisted onto the channel steel, and a pry bar is inserted into the grooves to move the equipment along the channel steel into the interior. Inside, rollers or a forklift are used to catch the equipment, thus completing the transfer. The entire installation process is quite cumbersome, with high installation costs and low work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile high-voltage switchgear installation and commissioning platform that is convenient to move and highly efficient, addressing the problem that existing high-voltage switchgear is inconvenient to move when encountering steps due to its heavy weight.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] A movable high-voltage switchgear installation and commissioning platform includes a vertically arranged base plate. A U-shaped groove is formed in the middle of the lower part of the base plate, and a traveling mechanism is provided in the U-shaped groove. The lower part of the base plate is divided into two legs by the U-shaped groove. The traveling mechanism includes a power component, a traveling plate, and a linkage structure. One end of the linkage structure is connected to the power component and rotates under the drive of the power component. The other end of the linkage structure is connected to the traveling plate. The traveling plate can extend from both sides of the U-shaped groove and protrude from the plane of the vertical sides of the base plate. When the traveling plate supports the ground, it can make the legs suspend in the air. A support platform is connected to the base plate. The support platform extends laterally and is used to place the high-voltage switchgear.

[0007] The present invention, employing the above technical solution, features a base plate and a support platform. The support platform can be used to place the high-voltage switchgear, thus only the base plate needs to be movable. A traveling mechanism is provided below the base plate, and the traveling mechanism and the support legs serve as two supports for the movement of the base plate. In use, a power component drives the linkage structure to rotate, which in turn drives the traveling plate to move. Since the support legs can be suspended when the traveling plate is on the ground, the base plate can be moved laterally by supporting the ground with the traveling plate. The rotation direction of the linkage structure can be adjusted to move the base plate up or down along the steps. The operation is convenient, the moving efficiency of the base plate is high, and it can meet the movement requirements of the base plate on the steps.

[0008] Furthermore, the power component is fixed to the side wall of the U-shaped groove, and a first connecting rod is fixed to one of its extended ends. The first connecting rod is hinged to a second connecting rod, and a traveling plate is connected to the lower end of the second connecting rod. The power component drives the first connecting rod to rotate, and the hinged connection between the first and second connecting rods causes the upper hinged end of the second connecting rod to move. During this process, the length direction of the second connecting rod remains vertical under the action of gravity. The traveling plate is connected to the lower part of the second connecting rod, thereby causing the traveling plate to move.

[0009] Furthermore, the power component is axially perpendicular to the sidewall of the U-shaped groove, and a vertically arranged stabilizing component is connected to the protruding end of the power component. The other end of the stabilizing component is fixed to the bottom of the U-shaped groove. The power component is a motor. The second connecting rod is hinged to the walking plate, and limiters extend from both sides of the hinged end of the second connecting rod. The two limiters are inclined and symmetrical, and a gap is left between the protruding ends of the limiters and the walking plate. An anti-slip pad is fixed to the side of the walking plate facing away from the second connecting rod. The stabilizing component is used to fix one end of the power component, so that the protruding end of the power component is not suspended in the air, thus improving the stability of the power component. The second connecting rod is hinged to the walking plate, and the second connecting rod is provided with limiters, so that the walking plate can rotate at a certain angle relative to the second connecting rod, which facilitates the adjustment of the walking plate according to the flatness of the ground when it is in contact with the ground, thereby improving the stability of the plate's movement.

[0010] Furthermore, the support platform is connected to a vertically positioned first cylinder and can move vertically under the drive of the first cylinder; the installation and commissioning platform has limit structures in the X, Y, and Z directions for the high-voltage switchgear placed on the support platform. The support platform can move vertically under the drive of the first cylinder, thus moving the high-voltage switchgear located on the support platform vertically; by setting limit structures in the X, Y, and Z directions for the high-voltage switchgear, the position of the high-voltage switchgear is fixed, improving the stability of the high-voltage switchgear when the base plate moves.

[0011] Furthermore, the support platform includes a support portion extending horizontally and a T-shaped latching portion extending toward the substrate. The substrate has a long, narrow latching groove that mates with the latching portion in a vertical direction. A limiting plate extends laterally from the top of the substrate and is parallel to the support portion. The limiting plate is fixed to the top of the first cylinder, and the bottom of the first cylinder is fixed to the support platform. The support portion and the limiting plate cooperate to form a Z-direction limiting. The latching portion mates with the latching groove, which is long and narrow and vertically oriented to facilitate movement of the latching portion within the groove. During the upward movement of the support portion with the high-voltage switchgear, the limiting plate limits the highest position of the high-voltage switchgear and can abut against the high-voltage switchgear to improve the stability of the switchgear's position.

[0012] Furthermore, there are two support sections. The lateral position of the limiting plate is located in the middle of the two support sections. A first rubber pad is provided on the top surface of the support section, and a second rubber pad is fixed to the side of the limiting plate facing the support section. A reinforcing section is provided on the lower side of the support section, forming a triangular support structure below the support section. The second rubber pad is located between the limiting plate and the high-voltage switchgear, providing protection for the high-voltage switchgear. The triangular structure formed by the reinforcing section ensures good stability of the support section.

[0013] Furthermore, a stop plate is fixed vertically on the side of the base plate facing the high-voltage switchgear, and a third rubber pad is fixed on the side of the stop plate facing the high-voltage switchgear. Multiple insertion slots parallel to the base plate are provided at the extended end of the support portion. A detachable L-shaped connector is snapped onto the base plate, and the connector cooperates with the stop plate to form an X-direction limiting position. The two sides of the high-voltage switchgear in the X direction can respectively abut against the stop plate and the connector, forming an X-direction limiting position. Because multiple insertion slots are provided, a suitable insertion slot can be selected according to the X-direction dimensions of the high-voltage switchgear to minimize the distance between the connector and the high-voltage switchgear, thereby improving the stability of the high-voltage switchgear's position. The third rubber pad provides cushioning and protection for the high-voltage switchgear.

[0014] Furthermore, the abutment plate is fixed to the base plate by mounting posts, which are positioned to avoid the snap-fit ​​groove. The bottom of the plug groove is magnetic, with the magnetic properties opposite to those of the insertable end. A fourth rubber pad is fixed to the side of the plug that abuts against the high-voltage switchgear, forming the vertical section of the plug. The horizontal section of the plug faces away from the high-voltage switchgear and has a snap-fit ​​groove. U-shaped overlapping members are fixed to both opposite sides of the base plate, forming a closed and hollow rectangular storage groove on the base plate, into which the plug can be snapped. The plug groove and the plug are magnetically opposed to each other, ensuring the stability of the plug after insertion. The snap-fit ​​groove facilitates the removal of the plug, and the storage groove formed by the overlapping members is used for storing the plug. The fourth rubber pad provides cushioning and protection for the high-voltage switchgear.

[0015] Furthermore, second cylinders are fixed on both lateral sides opposite to the support. One end of each second cylinder has a long, horizontally oriented push plate fixed to it. The push plate can be pushed out and abuts against the column base at the bottom of the high-voltage switchgear. A fifth rubber pad is fixed to the end of the push plate near the column base. The two push plates and the column base cooperate to form a Y-direction limit. After the high-voltage switchgear is stabilized, the second cylinders push the push plates against the column base to limit the Y-direction of the high-voltage switchgear.

[0016] Furthermore, a U-shaped handle is fixed to the side of the substrate facing away from the support, and the handle is arranged laterally. A trapezoidal groove is formed on the support leg laterally, dividing the bottom surface of the leg into a hinged fixed part and a rotating part. The rotating part is one side of the trapezoidal groove, and an inclined third cylinder is fixed inside the trapezoidal groove. One end of the third cylinder is hinged to the rotating part, and the other end is fixed to the inner wall of the trapezoidal groove. The handle serves as a handrail for the substrate, and the angle of the rotating part is adjustable under the action of the third cylinder. This allows the angle of the rotating part to be adjusted by the angle of the ground, ensuring that the rotating part maintains surface contact with the ground, guaranteeing the stability of the entire substrate, and facilitating the movement of the substrate on inclined surfaces.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] Because it has a base plate and a support platform, the support platform can be used to place the high-voltage switchgear, so only the base plate needs to be movable; and a traveling mechanism is provided under the base plate. The traveling mechanism and the support legs can serve as two supports for the movement of the base plate. In use, the linkage structure is rotated by a power component, and the linkage structure will drive the traveling plate to move. Since the support legs can be suspended in the air when the traveling plate is on the ground, the base plate can be moved laterally by supporting the ground through the traveling plate. The rotation direction of the linkage structure can be adjusted to drive the base plate to move up or down along the steps. It is easy to operate, the base plate has high moving efficiency, and it can meet the movement of the base plate on the steps. Attached Figure Description

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] like Figure 1A movable high-voltage switchgear installation and commissioning platform includes a vertically arranged base plate a. A U-shaped groove a1 is formed in the middle of the lower part of the base plate a, and a traveling mechanism b is provided in the U-shaped groove a1. The lower part of the base plate a is divided into two legs a2 by the U-shaped groove a1. The traveling mechanism b includes a power component b1, a traveling plate b2 and a connecting rod structure. One end of the connecting rod structure is connected to the power component b1 and rotates under the drive of the power component b1. The other end of the connecting rod structure is connected to the traveling plate b2. The traveling plate b2 can extend from both sides of the U-shaped groove a1 and protrude from the plane of the vertical sides of the base plate a. When the traveling plate b2 supports the ground, the legs a2 can be suspended in the air. A support platform c is connected to the base plate a. The support platform c extends laterally and is used to place the high-voltage switchgear.

[0036] The present invention, employing the above technical solution, has a base plate a and a support platform c. The support platform c can be used to place a high-voltage switchgear, so it is only necessary to make the base plate a movable. A traveling mechanism b is provided below the base plate a. The traveling mechanism b and the support leg a2 can serve as two supports for the movement of the base plate a. In use, the power component b1 drives the linkage structure to rotate, and the linkage structure drives the traveling plate b2 to move. Since the support leg a2 can be suspended when the traveling plate b2 is on the ground, the base plate a can be moved laterally by the support of the traveling plate b2. The rotation direction of the linkage structure can be adjusted to drive the base plate a to move up or down along the steps. The operation is convenient, the moving efficiency of the base plate a is high, and the movement of the base plate a on the steps can be satisfied.

[0037] Furthermore, the power component b1 is fixed to the side wall of the U-shaped groove a1, and a first connecting rod b3 is fixed to one of its extended ends. The first connecting rod b3 is hinged to a second connecting rod b4, and the lower end of the second connecting rod b4 is connected to a traveling plate b2. The power component b1 drives the first connecting rod b3 to rotate, and the first connecting rod b3 is hinged to the second connecting rod b4, thereby driving the upper hinged end of the second connecting rod b4 to move. During this process, the length direction of the second connecting rod b4 remains vertical under the action of gravity. The traveling plate b2 is connected below the second connecting rod b4, thereby driving the traveling plate b2 to move.

[0038] like Figures 2 to 4Furthermore, the axial direction of the power component b1 is perpendicular to the side wall of the U-shaped groove a1, and the extended end of the power component b1 is connected to a vertically arranged stabilizing component b5. The other end of the stabilizing component b5 is fixed to the bottom of the U-shaped groove a1. The power component b1 is a motor. The second connecting rod b4 is hinged to the walking plate b2, and limiters b6 extend from both sides of the hinged end of the second connecting rod b4. The two limiters b6 are inclined and symmetrical, and there is a gap between the extended end of the limiter b6 and the walking plate b2. An anti-slip pad b7 is fixed on the side of the walking plate b2 facing away from the second connecting rod b4. The stabilizer b5 is used to fix one end of the power component b1 so that the extended end of the power component b1 is not suspended in the air, thus improving the stability of the power component b1; the second link b4 is hinged to the walking plate b2, and the second link b4 is provided with a limiting component b6, so that the walking plate b2 can rotate at a certain angle relative to the second link b4, which facilitates the adjustment of the walking plate b2 according to the flatness of the ground when it is in contact with the ground, thereby improving the stability of the base plate a walking.

[0039] like Figure 6 Furthermore, the support platform c is connected to a vertically positioned first cylinder a13 and can move vertically under the drive of the first cylinder a13. The installation and commissioning platform has limit structures in the X, Y, and Z directions for the high-voltage switchgear placed on the support platform c. The support platform c can move vertically under the drive of the first cylinder a13, thus moving the high-voltage switchgear located on the support platform c vertically. By setting limit structures in the X, Y, and Z directions for the high-voltage switchgear, the position of the high-voltage switchgear is fixed, improving the stability of the high-voltage switchgear when the base plate a moves.

[0040] Furthermore, the support platform c includes a support portion c1 extending horizontally and a T-shaped latching portion c2 extending toward the substrate a. The substrate a has a long, narrow latching groove a3 that mates with the latching portion c2 in a vertical direction. A limiting plate a4 extends laterally from the top of the substrate a and is parallel to the support portion c1. The limiting plate a4 is fixed to the top of the first cylinder a13, and the bottom of the first cylinder a13 is fixed to the support platform c. The support portion c1 and the limiting plate a4 cooperate to form a Z-direction limiting. The latching portion c2 mates with the latching groove a3, and the latching groove a3 is long and narrow and is arranged vertically to facilitate the movement of the latching portion c2 within the latching groove a3. During the process of the high-voltage switchgear being placed on the support portion c1 and moving upward, the limiting plate a4 limits the highest position of the high-voltage switchgear, and the limiting plate a4 can abut against the high-voltage switchgear to improve the stability of the high-voltage switchgear's position.

[0041] Furthermore, there are two support parts c1. The limiting plate a4 is positioned laterally in the middle of the two support parts c1. A first rubber pad c3 is provided on the top surface of the support part c1, and a second rubber pad a5 is fixed to the side of the limiting plate a4 facing the support part c1. A reinforcing part c4 is provided on the lower side of the support part c1, forming a triangular support structure below the support part c1. The second rubber pad a5 is located between the limiting plate a4 and the high-voltage switchgear, providing protection for the high-voltage switchgear. The triangular structure formed by the reinforcing part c4 ensures good stability of the support part c1.

[0042] Furthermore, a stop plate a6 is fixed vertically on the side of the base plate a facing the high-voltage switchgear, and a third rubber pad a7 is fixed on the side of the stop plate a6 facing the high-voltage switchgear. Multiple insertion slots c8 parallel to the base plate a are provided at the extended end of the support part c1. A detachable L-shaped connector d is snapped onto the base plate a, and the connector d cooperates with the stop plate a6 to form an X-direction limiting position. The two sides of the high-voltage switchgear in the X direction can respectively abut against the stop plate a6 and the connector d, forming an X-direction limiting position. Because multiple insertion slots c8 are provided, a suitable insertion slot c8 can be selected according to the X-direction dimensions of the high-voltage switchgear to minimize the distance between the connector d and the high-voltage switchgear, thereby improving the stability of the high-voltage switchgear's position. The third rubber pad a7 provides buffering and protection for the high-voltage switchgear.

[0043] like Figure 7 and Figure 8 Furthermore, the abutment plate a6 is fixed to the base plate a by the mounting post a9, which avoids the snap-fit ​​groove a3; the bottom of the insertion groove c8 is magnetic, and its magnetic properties are opposite to those of the insertable end of the plug-in d; a fourth rubber pad d1 is fixed to the side of the plug-in d that abuts against the high-voltage switchgear, and this section forms the vertical section of the plug-in d; the horizontal section of the plug-in d is away from the high-voltage switchgear and has a snap-fit ​​groove d2; U-shaped overlapping members a15 are fixed to both opposite sides of the base plate a, and the overlapping members a15 form a closed and hollow rectangular storage groove on the base plate a, into which the plug-in d can be snapped. The plug-in groove c8 and the plug-in d are set by opposite magnetic properties to ensure the stability of the plug-in d after insertion; the snap-fit ​​groove d2 facilitates the removal of the plug-in d, and the storage groove formed by the overlapping members a15 is used to store the plug-in d; the fourth rubber pad d1 provides cushioning and protection for the high-voltage switchgear.

[0044] Furthermore, a second cylinder c5 is fixed on each of the two lateral sides opposite to the support c1. A long, horizontally oriented push plate c6 is fixed to one end of each second cylinder c5. The push plate c6 can be pushed out and abuts against the column foot at the bottom of the high-voltage switchgear. A fifth rubber pad c7 is fixed to the end of the push plate c6 near the column foot. The two push plates c6 and the column foot cooperate to form a Y-direction limit. After the high-voltage switchgear is stabilized, the second cylinder c5 pushes the push plate c6 against the column foot to limit the Y-direction of the high-voltage switchgear.

[0045] like Figure 5 Furthermore, a U-shaped handle a10 is fixed to the side of the substrate a facing away from the support c1, and the handle a10 is arranged laterally. A trapezoidal groove is formed on the support leg a2 laterally, dividing the bottom surface of the support leg a2 into a hinged fixed part a11 and a rotating part a12. The rotating part a12 is one side of the trapezoidal groove, and an inclined third cylinder a14 is fixed inside the trapezoidal groove. One end of the third cylinder a14 is hinged to the rotating part a12, and the other end is fixed to the inner wall of the trapezoidal groove. The handle a10 serves as a handrail for the substrate a. The angle of the rotating part a12 is adjustable under the action of the third cylinder a14, meaning the angle of the rotating part a12 can be adjusted by the angle of the ground, ensuring that the rotating part a12 maintains surface contact with the ground, guaranteeing the stability of the entire substrate a, and facilitating the movement of the substrate a on inclined surfaces.

[0046] The snap-fit ​​part c2 can slide within the snap-fit ​​groove a3, which forms a sliding groove for the support platform c to slide vertically along the base plate a. The two second cylinders c5 are arranged back to back. When there is one support part c1, the two second cylinders c5 are located on opposite sides of the support part c1; when there are two support parts c1, the two second cylinders c5 are respectively arranged on the two support parts c1 and are arranged back to back.

[0047] As shown in the figure, 2 to Figure 4 The diagrams show the structure of the walking mechanism b and the support leg a2 when the base plate a moves up and down the steps.

[0048] When placing the high-voltage switchgear on the installation and commissioning platform and transferring it: the first cylinder a13 drives the support c1 to adjust to a suitable height, and a crane is used to move the high-voltage switchgear to be transferred onto the support c1. The high-voltage switchgear is protected by the limit structure in the XYZ directions. Then, the traveling mechanism b is started, so that the power component b1 drives the first connecting rod b3 to perform a circular motion, which drives the second connecting rod b4, which is hinged to the first connecting rod b3, to move laterally. During this process, the length direction of the second connecting rod b4 remains vertical, and it drives the traveling plate b2 to move. The traveling plate b2 and the support leg a2 alternately contact the ground to realize the transfer of the high-voltage switchgear. When the power component b1 is started, the operator can hold the U-shaped handle a10 to assist in the movement of the base plate a and ensure the smooth transfer of the high-voltage switchgear.

[0049] When the high-voltage switchgear is moved up and down the steps: the power component b1 drives the first connecting rod b3 to move in a circular motion, thereby moving the second connecting rod b4 which is hinged to the first connecting rod b3. During this process, the second connecting rod b4 remains vertical in the length direction and drives the traveling plate b2 to move. By alternating between the traveling plate b2 and the support leg a2, the bottom of the base plate a comes into contact with steps of different heights. During this process, the support leg a2 and the traveling plate b2 will alternately act as fulcrums to lift one of them off the ground and into contact with the next step surface. This cycle is repeated to realize the position transfer of the high-voltage switchgear (base plate a).

[0050] When the high-voltage switchgear is moved on an inclined plane: the contraction of the third cylinder a14 is controlled according to the angle of the inclined plane to drive the rotating part a12 to rotate to adjust the angle and keep the rotating part a12 in contact with the inclined plane. Then the traveling mechanism b is started to operate to drive the high-voltage switchgear to move.

[0051] During the limit protection process for the high-voltage switchgear: First, place the high-voltage switchgear on the support c1, ensuring the rear side of the switchgear is flush against the abutment plate a6. Pull the connector d out of the slot in the lap joint a15, so that one side of the fifth rubber pad c7 faces the high-voltage switchgear. Insert the connector d into the connector slot c8, ensuring the fifth rubber pad c7 is flush against the high-voltage switchgear, thus limiting the switchgear's X-axis movement. Simultaneously, activate the two second cylinders c5, causing them to push the push plate c6 against the column base of the high-voltage switchgear, thus limiting the switchgear's Y-axis movement. Then, control the first cylinder a13 to move the support platform c upwards until the high-voltage switchgear abuts against the limit plate a4, thus limiting the switchgear's Z-axis movement. Furthermore, the aforementioned components that come into contact with the high-voltage switchgear are all equipped with rubber pads on the side facing the high-voltage switchgear, and these rubber pads abut against the high-voltage switchgear. This structure provides good protection for the high-voltage switchgear and prevents the surface of the high-voltage switchgear from being scratched during movement.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
