Description

Technical Field

[0001] This utility model relates to the field of GCB arc-extinguishing chamber flipping technology, specifically to a GCB arc-extinguishing chamber flipping frame. Background Technology

[0002] In the production and maintenance of gas circuit breakers (GCBs), the GCB arc-extinguishing chamber is one of the core components, which is relatively large and heavy. When performing maintenance, repairs, or assembly operations on the GCB arc-extinguishing chamber, it is often necessary to rotate it to allow workers to operate from different angles.

[0003] Currently, the most common method for rotating GCB arc-extinguishing chambers is manual labor combined with simple hoisting equipment. This method has many drawbacks: on the one hand, manual rotation is labor-intensive, inefficient, and makes it difficult to precisely control the rotation angle; on the other hand, due to the large weight of the GCB arc-extinguishing chamber, manual rotation poses significant safety hazards, easily leading to collisions, falls, and other accidents, which may not only damage the arc-extinguishing chamber but also threaten the personal safety of the operators.

[0004] In addition, some existing flipping devices have limited functions and can only perform simple flipping actions. They cannot flexibly adjust the position of the GCB arc-extinguishing chamber. When moving the arc-extinguishing chamber from its storage location to the maintenance station or removing it from the flipping frame, the operation is very inconvenient, which further affects work efficiency.

Detailed Implementation

[0046] Example 1:

[0047] like Figure 1 , 2 As shown in Figures 3, 4, and 5, a GCB arc-extinguishing chamber turning frame includes a base 1, which serves as the supporting foundation for the entire turning frame. The base 1 is preferably made of high-strength steel, such as Q235 steel, which has good stability and load-bearing capacity.

[0048] The base 1 has several rollers 101 at its bottom. The rollers 101 are preferably roller structures with braking function, equipped with roller drive motors, or hub motors. This not only facilitates the overall movement of the tilting frame, but also allows the tilting frame to be fixed in the required position by braking during operation, preventing it from moving accidentally.

[0049] The top of the base 1 is provided with a flipping mechanism 3, which is used to connect to and flip the GCB arc-extinguishing chamber.

[0050] Specifically, the flipping mechanism 3 includes two fixed rods 301, which are arranged in parallel and symmetrically on the top of the base 1 to provide stable support for the flipping operation.

[0051] A connecting plate 303 is rotatably mounted on the fixed rod 301. The GCB arc-extinguishing chamber is connected between the two connecting plates 303. The arc-extinguishing chamber is rotated by the rotation of the connecting plate 303. The connection between the GCB arc-extinguishing chamber and the connecting plate 303 adopts the existing common method of connecting GCB arc-extinguishing chambers, such as by screws or bolts.

[0052] A third hydraulic cylinder 305 is provided between the end of the connecting plate 303 and the fixed rod 301. The third hydraulic cylinder 305 serves as a driving component, and its extension and retraction movement can drive the connecting plate 303 to rotate around the connection point with the fixed rod 301, thereby realizing the flipping action of the GCB arc extinguishing chamber.

[0053] Furthermore, the fixed rod 301 is slidably connected to the movable rod 302, which can slide up and down along the length of the fixed rod 301 to adjust the height of the connecting plate 303 and the connected GCB arc-extinguishing chamber.

[0054] The top end of the movable rod 302 is rotatably connected to one end of the connecting plate 303 via the fixed shaft 304, allowing the connecting plate 303 to rotate around the fixed shaft 304. The other end of the connecting plate 303 is hinged to one end of the third hydraulic cylinder 305, and the other end of the third hydraulic cylinder 305 is hinged to a connecting block 306, which is fixedly connected to the movable rod 302.

[0055] In use, the extension and retraction of the third hydraulic cylinder 305 can be effectively transmitted to the connecting plate 303, driving it to rotate and completing the flipping of the GCB arc-extinguishing chamber.

[0056] Furthermore, a groove 307 is provided on one side of the fixed rod 301, and the movable rod 302 is slidably connected in the groove 307. The groove 307 guides and limits the sliding of the movable rod 302, ensuring the stability of the movement of the movable rod 302.

[0057] The top of the fixed rod 301 is provided with a fixed plate 309, and the movable rod 302 slides through the fixed plate 309. The fixed plate 309 further limits the movable rod 302 to prevent it from deviating during the sliding process.

[0058] The bottom end of the movable rod 302 is equipped with a fourth hydraulic cylinder 308. The cylinder body of the fourth hydraulic cylinder 308 is fixed on the base 1 or the fixed rod 301. The piston rod is connected to the bottom end of the movable rod 302. The movable rod 302 is driven to slide up and down along the slide groove 307 by the extension and retraction of the fourth hydraulic cylinder 308, so as to realize the adjustment of the height of the GCB arc extinguishing chamber.

[0059] In a further embodiment, a support frame 102 is provided on the top of the base 1. The support frame 102 is made of welded steel and has high strength and stability, and is used to support the removal mechanism 2.

[0060] The top of the support frame 102 is provided with a removal mechanism 2, which is used to remove or move the components of the GCB arc-extinguishing chamber from the flipping mechanism 3 or other positions for easy transfer and operation.

[0061] A ladder is provided on the side of the support frame 102, which makes it easy for staff to climb to the top of the support frame 102 to operate or maintain the removal mechanism 2.

[0062] Furthermore, the removal mechanism 2 includes a fixed frame 201 disposed on the top of the support frame 102, and the fixed frame 201 is the basic frame of the removal mechanism 2.

[0063] The fixed frame 201 is slidably connected to the movable frame 202, and the movable frame 202 can slide relative to the fixed frame 201. A plurality of first hydraulic cylinders 203 are provided between the movable frame 202 and the fixed frame 201, and the first hydraulic cylinders 203 are used to drive the movable frame 202 to slide relative to the fixed frame 201.

[0064] The bottom of the movable frame 202 is provided with a mounting plate 207. The mounting plate 207 is used to install the GCB arc-extinguishing chamber. The mounting plate 207 fixes the parts of the GCB arc-extinguishing chamber that need to be moved. The mounting plate 207 is connected to the parts of the GCB arc-extinguishing chamber that need to be moved in an existing way, such as screw connection. The mounting plate 207 is a plate body adapted to the connection position of the GCB arc-extinguishing chamber.

[0065] The fixed frame 201 is a U-shaped frame, and a guide groove is provided on the inner side of the fixed frame 201. The guide groove guides the sliding of the movable frame 202. The movable frame 202 is slidably connected in the guide groove and can slide out from the opening of the fixed frame 201, which facilitates the removal of the GCB arc-extinguishing chamber from the fixed frame 201.

[0066] During movement, preferably, the movement is restricted by a limiting block, which is fixed to the end of the movable frame 202 and slidably connected to the limiting groove provided in the guide groove, so as to prevent the movable frame 202 from sliding out as a whole.

[0067] The first hydraulic cylinder 203 is located on the side of the fixed frame 201. Its cylinder body is connected to the fixed frame 201, and its piston rod is connected to the movable frame 202. The movable frame 202 slides along the guide groove by the extension and retraction of the first hydraulic cylinder 203.

[0068] A sliding plate 204 is slidably connected to the movable frame 202, and the sliding plate 204 can slide relative to the movable frame 202. A second hydraulic cylinder 205 is provided between the sliding plate 204 and the movable frame 202, and the second hydraulic cylinder 205 drives the sliding plate 204 to slide relative to the movable frame 202. The mounting plate 207 is fixed to the bottom of the sliding plate 204 and moves with the sliding plate 204, thereby driving the GCB arc-extinguishing chamber to adjust its position in another direction; or enabling the GCB arc-extinguishing chamber to move to a further position, so as to facilitate the movement of the GCB arc-extinguishing chamber or the GCB arc-extinguishing chamber assembly.

[0069] The movable frame 202 has a wheel groove, and guide wheels 206 are provided on both sides of the sliding plate 204. The guide wheels 206 are movably connected in the wheel groove. The cooperation between the guide wheels 206 and the wheel groove reduces the friction between the sliding plate 204 and the movable frame 202, making the sliding plate 204 slide more smoothly and stably.

[0070] The hydraulic cylinders mentioned above are preferably HSG type hydraulic cylinders, which are connected to the existing hydraulic control system and connected and controlled in the existing manner.

[0071] When in use, the GCB arc-extinguishing chamber is hoisted between the two fixed rods 301 and then connected by the connecting plate 303. During the testing process, it can be flipped over as needed.

[0072] When the GCB arc-extinguishing chamber is flipped to the vertical position, the end of the GCB arc-extinguishing chamber is connected to the mounting plate 207. Then, the GCB arc-extinguishing chamber is split up and down. The split GCB arc-extinguishing chamber is then removed by the removal mechanism 2, thus separating the GCB arc-extinguishing chamber for easy inspection by the staff.

[0073] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
