Description

Technical Field

[0001] This utility model relates to the field of air-filled cabinet technology, specifically to a movable air box flipping device for an adjustable-width air-filled cabinet. Background Technology

[0002] Gas-insulated switchgear, with its significant advantages such as compact structure, safety and reliability, strong environmental adaptability, and long maintenance-free cycle, is widely used in key areas such as urban power grids, rail transit, large industrial and mining enterprises, and new energy power plants. Its core design concept lies in completely sealing high-voltage live components such as circuit breakers, disconnectors, and grounding switches within a closed metal gas chamber filled with SF6 gas or environmentally friendly gas with excellent insulation properties. This fully enclosed structure not only greatly improves the insulation strength and arc-extinguishing capability of the equipment, effectively resisting the influence of the external environment, but also fundamentally ensures the safety of maintenance personnel and significantly reduces the equipment's footprint, making it an ideal choice for urban intensive power supply and space-constrained locations.

[0003] The performance of a gas-insulated switchgear (GES) hinges on the manufacturing quality of the gas chamber. The production process involves complex welding techniques and the precision assembly of numerous internal components, including insulators, conductor connectors, and operating mechanism connectors. A key production challenge lies in the frequent and safe large-angle rotation of the metal gas chamber shell to complete the installation of components in different locations (such as the top, bottom, and sides), weld quality checks, internal cleaning, and subsequent sealing checks. In traditional production methods, the gas chamber is often placed on a simple support frame, relying on manual prying, crane assistance, or multiple people working together to rotate it—a method that is neither safe nor efficient.

[0022] Example 1 A width-adjustable gas holder mobile gas box tilting device. Figure 1 A side view of the overall structure of one embodiment of the present invention is shown; Figure 2 A front view of the overall structure of one embodiment of the present invention is shown, as follows: Figure 1 and Figure 2 As shown, it includes: Support component 1, a pair of clamping components 2, drive component 3, and adjustment component 4; The support assembly 1 includes a pair of support frames 110 and a support platform 120. The support platform 120 is disposed on the target plane to bear the overall weight of the device and provide a stable operating reference. The pair of support frames 110 are disposed at both ends of the support platform 120 to support the clamping assembly 2 and withstand the torque and lateral force generated during the air box flipping process. In this embodiment, the bottom of the support platform 120 is provided with casters 121, which are used to adjust the position of the flipping device; the casters are provided with a brake locking structure. The casters 121 are used to enable flexible movement of the flipping device in the workshop or work site, allowing operators to easily adjust the position and orientation of the device according to production needs, improving tooling adaptability and operational convenience. The casters 121 can rotate independently, achieving 360° omnidirectional movement, while the bottom structure can bear the overall weight of the flipping device and the clamping air box. To ensure safety during the flipping operation, the casters 121 are equipped with a brake locking structure. After the operator moves the flipping device to the designated position, the casters 121 can be fixed by the brake device to prevent displacement or slippage during the flipping of the air box, ensuring the stability of the support platform and clamping components. The brake locking structure can take the form of a foot pedal brake, manual knob locking, or self-locking spring mechanism, which can quickly lock and easily release, balancing operational convenience and safety. The support frame 110 is vertically fixed to the support platform 120 through a continuous full welding process. It is mainly made of 40 square steel, and the frame is equipped with a reinforcing rib array to ensure the strength and lightweight of the platform.

[0023] A pair of clamping components 2 are respectively disposed at the top of a pair of support frames 110. The driving component 3 is connected to the clamping component 2 to provide driving force, causing the clamping component 2 to rotate, thereby driving the air box of the air chamber to rotate, achieving stepless rotation from 0° to 180°. The pair of clamping components 2 are respectively disposed at the top of the support frame 110 to fix the air box of the air chamber. In this embodiment, the clamping component 2 is connected to the support frame 110 through the bearing component 5. The bearing component 5 adopts a three-point support or rolling bearing layout, which can convert the sliding friction during the air box flipping process into rolling friction, thereby significantly reducing operating resistance and improving the flipping stability and ease of use. The clamping component 2 is configured as a butterfly clamp, and the butterfly clamp, the output shaft of the driving component 3 and the bearing component 5 are coaxially arranged. The clamping component 2 is provided with a connecting through hole 210, and the clamping component 2 is connected to the air box of the air chamber through the connecting through hole 210. The clamping assembly 2 is configured as a butterfly clamp structure. The butterfly clamp, the output shaft of the drive assembly 3, and the bearing assembly 5 are arranged coaxially, ensuring uniform force distribution and stable operation during rotation. The butterfly clamp connects to the gas chamber of the gas cabinet via connecting through holes 210. The connection method can be bolt insertion, nut tightening, or other reliable methods to achieve clamping and fixation. The size, position, and number of connecting through holes 210 are designed according to the layout of the gas chamber's welded studs, allowing the gas chamber to cooperate with the clamping assembly in a stress-free state, ensuring that the gas chamber is not squeezed or damaged during rotation.

[0024] The drive assembly 3 is connected to the clamping assembly 2 to provide the flipping power. The drive assembly 3 can adopt a structure of motor plus worm gear reducer, with a self-locking function, which can fix the air box at any angle position to ensure the safety and accuracy of the flipping operation. The power of the drive assembly is transmitted to the air box through the clamp bearing to achieve stepless flipping from 0° to 180°. The output shaft of the drive assembly 3 is coaxially arranged with the bearing assembly 5. The drive assembly 3 is connected to the clamping assembly 2 to provide the flipping power, so that the clamping assembly 2 drives the air box of the inflation cabinet to rotate and flip. In this embodiment, the drive assembly 3 can adopt a structure of motor and worm gear reducer, where the motor provides rotational power, the worm gear reducer realizes deceleration and torque amplification, and has a self-locking function, which can prevent the clamping assembly 2 and the air box from rotating in opposite directions under the action of external force, thereby fixing the air box at any angle position and realizing the safety and accuracy of the flipping process.

[0025] The output shaft of the drive assembly 3 is coaxially arranged with the clamping assembly 2 and the bearing assembly 5, making the power transmission path direct and the force evenly distributed, reducing the impact of lateral torque on the air box and support frame. During the flipping process, the bearing assembly 5 provides rolling support, reduces frictional resistance, and improves the flipping stability, allowing a single person to easily complete the stepless flipping operation of the air box from 0° to 180°.

[0026] The adjustment component 4 is disposed at the connection between the support frame 110 and the support platform 120, and is used to adjust the distance between the pair of support frames 110, thereby adjusting the clamping of the pair of clamping components 2 for gas-filled cabinets of different widths. In this embodiment, the adjustment component 4 includes a sliding component 410; the sliding component 410 includes a slider 411 and a slide rail 412; The slider 411 is disposed at the end of the support frame 110 near the support platform 120, and the slide rail 412 is disposed on the end face of the support platform 120 near the support frame 110. The slider 411 is slidably connected to the slide rail 412. By sliding along the length of the slide rail 412, the slider 411 allows the support frame 110 to be positioned relative to the support platform 120 to accommodate gas chambers of different widths, ensuring that the clamping assembly 2 can stably and reliably clamp the gas chamber. The materials and surface treatments of the slide rail 412 and the slider 411 can be wear-resistant metals or reinforced composite materials, and rolling bearings or bushings can be provided on the sliding surfaces to reduce frictional resistance and improve adjustment smoothness and durability. The slide rail length and slider stroke can be determined according to the maximum gas chamber width and the support frame design to ensure coverage of all expected gas chamber specifications. In this embodiment, the two slide rails 412 are fixed parallel to both sides of the support platform 120 by countersunk bolts and locating pins. The slider 411 forms a precision rolling guide pair with the slide rail 412 through the internal circulating balls.

[0027] Furthermore, in this embodiment, the adjustment component 4 also includes a locking component, which is used to fix the slider 411 after it has completed the adjustment along the slide rail 412; The locking component includes a bolt locking structure or a nut clamping structure, which can lock the slider 411 at a target position on the slide rail 412. The bolt locking structure secures the slider 411 by passing a bolt through the mating hole between the slider and the support platform 120, preventing movement of the slider on the slide rail. The nut clamping structure applies pressure to the contact surface between the slider and the support platform to fix the slider. The locking component can be designed with different specifications of bolts or nuts to suit different adjustment precision and ease of operation. It can also be combined with washers or anti-slip bushings to increase friction and improve locking reliability.

[0028] In this embodiment, the locking component, in cooperation with the slider 411 and the slide rail 412, enables rapid locking and unlocking, allowing operators to quickly adjust and fix the support frame spacing, thus improving operational efficiency. Simultaneously, the locking component effectively prevents accidental slippage of the support frame 110 or clamping assembly 2 due to external forces, vibrations, or the weight of the air box during adjustment, ensuring the stability and safety of the tilting device during operation.

[0029] Furthermore, in this embodiment, the adjustment component 4 also includes a sliding drive component connected to the support frame 110, used to drive the slider 411 to move along the slide rail 412. The sliding drive component includes a lead screw and a rotating handwheel or electric push rod structure, which can cooperate with the locking component to fix the slider 411 after adjustment. The sliding drive component can adopt a mechanical structure of lead screw and rotating handwheel. The operator drives the lead screw to rotate by rotating the handwheel, which drives the slider to move along the slide rail, achieving smooth and controllable adjustment. The lead screw and slider are connected by a nut or ball screw structure, which can ensure transmission accuracy and smooth adjustment. Alternatively, the sliding drive component can adopt an electric push rod structure, which controls the extension and retraction of the push rod by a motor, driving the slider to move along the slide rail, realizing automated or semi-automated adjustment, reducing the labor intensity of the operator and improving operating efficiency.

[0030] After adjustment, the sliding drive component can be used in conjunction with the locking component to fix the slider 411 at the target position on the slide rail. The locking component securely locks the slider by bolting, nut tightening, or similar structures, ensuring that the support frame 110 does not shift during the flipping operation, maintaining the stability and safety of the clamping assembly 2 and the air box. Whether manual screw adjustment or electric push rod adjustment is used, single-person operation can complete the clamping adjustment of air boxes of different widths, ensuring that the clamping assembly 2 is subjected to uniform force and runs smoothly during the flipping process, improving the applicability and reliability of the flipping device.

[0031] The operation process of using the adjustable-width air tank mobile air box tilting device includes: Step 1: Unlock the locking components and pull the support frame 110 outward along the slide rail 412 to the loading mark. Use a bridge crane to lift the air box above the tilting device, and fine-tune the crane height to ensure that the air box axis is parallel and at the same height as the air box clamping assembly 2.

[0032] Step 2: Push the support frame 110 inward to the pre-installed scale position, and rotate a pair of clamping components 2 to align the connecting through hole 210 with the welding stud on the side wall of the air box.

[0033] Step 3: Continue support frame 110 to the working scale position. At this point, the pair of clamping components 2 can just fit against the side wall of the air box, and the air box welding stud naturally passes through the connecting through hole 210 without stress. Screw the mounting nut into the welding stud so that the clamping components 2 form a surface contact and are pressed tightly against the side wall of the air box.

[0034] Step 4: Shake the input shaft of the drive assembly 3 handwheel, which drives the clamping assembly 2 to rotate via the worm gear pair, thereby achieving stepless rotation of the air box from 0° to 180°.

[0035] Step 5: Release the brakes on the casters and manually push the tilting device to move it along the preset path to the next workstation.

[0036] Step 6: Flip the air box to the reference position with the top surface facing up, use a bridge crane to lift the air box, preload the hook, loosen the mounting nuts on the outside of a pair of clamping components 2, pull the support frame 110 to the loading position, and remove the air box along the slide rail 412. The air box is lifted away from the working area of ​​the flipping device.

[0037] This invention utilizes an adjustable support frame and a pair of clamping components to achieve rapid and stable clamping of gas boxes of varying widths. A reducer drives the gas box clamping mechanism to rotate, combined with three-point bearing rolling support, allowing a single person to perform stepless rotation of the gas box from 0° to 180°. Rotation is easy and the angle is precisely controllable, effectively avoiding the risk of gas box compression or injury caused by manual prying. The collaborative design of the sliding rail-type adjustable bearing support platform and the integrated welding platform ensures the coaxiality of the reducer output shaft and the three bearings, eliminating off-center load torque caused by gas box deformation and ensuring the gas box's airtightness compliance rate. Inheriting the advantages of linear displacement slide rails and universal wheel platforms, a single fixture can flexibly move between multiple workstations, improving production efficiency, reducing reliance on large equipment and crane precision, and offering convenient, safe, and reliable operation.
