Description

Technical Field

[0001] This application relates to the field of GIS outgoing bushing disassembly and assembly, specifically to a GIS outgoing bushing transport and disassembly / assembly device. Background Technology

[0002] With the development of the power industry, the increase in transmission voltage levels, and the formation of large-scale inter-regional power grids, high demands are placed on the reliability of power transmission and transformation equipment. Compared with traditional open-type high-voltage equipment, gas-insulated switchgear (GIS) has significant advantages: compact structure, greatly reducing the footprint of the entire unit; unaffected by external environment, resulting in high operational reliability; and long maintenance cycles. Since its introduction in the 1960s, GIS has developed rapidly and occupies an important position in power transmission and transformation systems. However, there are several inconveniences in the installation and maintenance of GIS outgoing bushings (Note: This invention mainly solves the problem of disassembling and assembling the main component of GIS, the outgoing bushing). Currently, the main problems are as follows:

[0003] The feasibility of disassembly and assembly operations under the existing conditions is poor.

[0004] The installation of GIS outgoing bushings is generally located outdoors. The existing installation method usually uses scaffolding and cranes. However, since the outgoing bushings are not installed vertically or horizontally, but at a specific angle, the angle cannot be adjusted by a single crane. Additional cranes or manual labor are required to change the installation angle of the outgoing bushings. This method is not only time-consuming and labor-intensive, but also cannot guarantee the accuracy of the angle adjustment.

[0005] Existing disassembly and assembly methods have poor safety.

[0006] When using scaffolding or poles for lifting and dismantling operations, it is difficult to select the support points for the scaffolding, and the scaffolding is often too flimsy to guarantee its load-bearing capacity. GIS cable outlet bushings are prone to swaying, compromising safety. Moreover, these operations are typically carried out using rented equipment, which lacks regular and professional safety testing and monitoring, thus compromising equipment reliability.

[0007] Existing disassembly and assembly methods have a negative impact on the disassembly and assembly process of GIS equipment.

[0008] When using a crane for hoisting operations, especially during the alignment of the outgoing bushing, the installation position of the outgoing bushing is not horizontal or vertical. Therefore, the hoisting equipment needs to be precisely adjusted in all directions. During this process, the natural swaying of the slings will greatly affect the reliability and accuracy of the alignment. If the contact surfaces of the outgoing bushing are not aligned correctly, it can lead to damage to the flange sealing surface due to collision or friction during disassembly and assembly, twisting or displacement of the sealing rubber ring, and uneven internal stress on the contact surface. This greatly increases the risk of quality defects and the labor intensity.

[0009] Existing disassembly and assembly methods involve high labor intensity for workers.

[0010] Due to the heavy weight, complex shape, and complicated installation location of GIS outgoing bushings, and the lack of professional mechanized disassembly and assembly equipment, a large amount of manual labor is required, such as carrying by hand, shoulder carrying, and rope pulling, which is labor-intensive and inefficient. Summary of the Invention

[0011] The purpose of this application is to provide a GIS outgoing bushing transport and disassembly device, which has a simple structure, relatively complete functions, and can disassemble and assemble GIS outgoing bushings. Moreover, its production cost is lower than that of other large-scale mechanical equipment, and it has a high cost performance.

[0012] To achieve the above objectives, this application provides the following technical solution:

[0013] This application provides a GIS outgoing sleeve transportation and disassembly device, including a lifting electric cylinder assembly, a robotic arm assembly, a special clamping assembly, a gantry frame, and an AGV transfer module.

[0014] The gantry frame is mounted on the AGV transfer module;

[0015] The lifting electric cylinder assembly is installed on the gantry frame;

[0016] The robotic arm assembly is installed below the lifting cylinder assembly, and the installation position of the GIS outgoing sleeve is adjusted by the swing angle of the robotic arm assembly.

[0017] The dedicated clamping assembly is installed below the robotic arm assembly to firmly clamp the GIS outgoing sleeve;

[0018] The angle of the dedicated clamping component changes along with the angle of the robotic arm component, thereby achieving the desired installation angle for the GIS cable outlet sleeve.

[0019] The lifting electric cylinder assembly includes an electric cylinder, which is driven by a lifting motor to perform telescopic movement. A guide rod is installed on a rotating disk, and the electric cylinder is installed on a connecting bracket and connected to the gantry frame through the connecting bracket. The rotating disk is installed below the electric cylinder and moves with the telescopic movement of the electric cylinder. The rotating motor drives the rotating disk to rotate through a drive gear.

[0020] The robotic arm assembly includes a flange tray assembly connected to a rotary table. The first and second servo electric cylinders are both installed below the flange tray assembly and are respectively connected to a connecting plate and a linear sliding cylinder. A transition plate is installed on both sides of the third servo electric cylinder. A sliding rail is installed on the transition plate. A mounting plate is installed on the first moving slider and connected to the extension rod of the third servo electric cylinder, and moves in a telescopic motion together with it.

[0021] The dedicated clamping assembly includes a gear bracket mounted under the mounting plate. The driving gear is connected to the external gear drive motor and mounted on the side of the gear bracket via a fixed bracket. The driven gear is mounted on both sides of the driving gear and meshes with it. The external gear is mounted under the gear bracket and meshes with the internal gear located inside the gear bracket, thereby achieving concentric rotation. The mounting box is mounted on the outside of the external gear and houses a first drive gear connected to the external first drive motor. The rack meshes with the first drive gear. Driven by the first drive motor, the first drive gear drives the rack to move, which in turn drives the dedicated clamp connected to the rack to perform a clamping action. A reinforcing rod is located below the rack and connected to the dedicated clamp to improve its structural strength. The dedicated clamp has a special clamping angle that perfectly fits the outward tilt angle of the GIS cable outlet sleeve, and soft material is applied to the contact surface to prevent damage to the workpiece during clamping.

[0022] The gantry includes a column assembly located on both sides, a crossbeam assembly installed between the two column assemblies, a track moving assembly installed on the crossbeam assembly, and a second connecting plate installed on the track moving assembly.

[0023] The column assembly includes a mounting sleeve located on the top side of the three-section telescopic column and cooperating with the third mounting plate. The first mounting hole is located below the mounting sleeve and cooperates with the second mounting hole. The reinforcing rib is located on the side of the three-section telescopic column, and the mounting base plate is located below the three-section telescopic column.

[0024] The crossbeam assembly includes upper and lower moving tracks, which are installed above the crossbeam. A moving rack is installed between the upper and lower moving tracks. A third mounting plate is located on both sides of the crossbeam, and a second mounting hole is located on the lower sides of the crossbeam.

[0025] The track moving assembly includes a second drive motor mounted on a mounting base plate and connected to a second drive gear. A second moving slider is mounted below the mounting base plate and cooperates with the moving tracks in the column assembly and beam assembly.

[0026] The AGV movement module includes an emergency button installed at the rear of the vehicle body. A status display screen shows the status of the entire device. The load-bearing vehicle body supports the weight of the device and contains a large-capacity lithium battery to power the entire device. Tracked wheels are installed around the load-bearing vehicle body. The AGV movement module enables the entire device to move.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. This invention employs a gantry structure with a crossbeam width of 3.6m and a column height of 2-5m. An AGV (Automated Guided Vehicle) trolley is installed below the column. This trolley uses tracked wheels and operates in a linkage manner, which can drive the gantry structure to move back and forth and rotate. When passing through certain height restrictions, the column height can be lowered or the equipment can be disassembled and assembled, thereby achieving the purpose of entering the working position. Moreover, the device has multiple degrees of freedom of movement in vertical and horizontal directions, and can accurately adjust the angle of the cable outlet sleeve to ensure the installation angle and installation quality of the GIS cable outlet sleeve.

[0029] 2. This invention adopts an innovative solution of installing an automated robotic arm on a gantry crane and using a dedicated clamp, which can perfectly fit and rigidly clamp the GIS outgoing bushing. By adjusting the angle of the robotic arm, the GIS outgoing bushing can be easily positioned at various installation angles. The docking process uses a servo electric cylinder, which improves the reliability and accuracy of alignment and avoids various defects such as bumps and angle changes caused by the natural swaying of the sling. This meets the product assembly process requirements and improves the product assembly quality. At the same time, due to the use of rigid clamping, shaking during the installation process is avoided, and no other accessories are needed for support, greatly improving safety.

[0030] 3. This invention uses lithium batteries as the main power source. The equipment will not pollute the GIS disassembly and assembly environment during self-propelled movement and disassembly. The bottom movement is carried out by AGV trolleys with tracked wheels. The movement is diversified. Special clamps automatically hold the equipment. It is equipped with a remote control operating system and has a high degree of automation, which greatly reduces the labor intensity of the installation personnel.

[0031] 4. The present invention has a simple structure and relatively complete functions. It can disassemble and assemble GIS outgoing bushings, and its production cost is lower than that of other large-scale mechanical equipment, making it cost-effective. Attached Figure Description

[0049] like Figures 1 to 14 As shown in the figure, this application provides a GIS outgoing sleeve transportation and disassembly equipment, including a lifting electric cylinder assembly 1, a robotic arm assembly 2, a special clamping assembly 3, a gantry frame 5, and an AGV transfer module 6.

[0050] The gantry frame 5 is installed on the AGV transfer module 6;

[0051] The lifting electric cylinder assembly 1 is installed on the gantry frame 5;

[0052] The robotic arm assembly 2 is installed below the lifting cylinder assembly 1, and the installation position of the GIS outgoing sleeve 4 is adjusted by the swing angle of the robotic arm assembly 2.

[0053] The dedicated clamping component 3 is installed below the robotic arm component 2 to tightly clamp the GIS outgoing sleeve 4;

[0054] The angle of the dedicated clamping component 3 changes together with the angle of the robotic arm component 2, thereby achieving the installation angle of the GIS outgoing sleeve 4.

[0055] The lifting electric cylinder assembly 1 includes an electric cylinder 101, which is driven by a lifting motor 102 to perform telescopic movements. A guide rod 103 is mounted on a rotating disk 105. The electric cylinder 101 is mounted on a connecting bracket 104 and connected to the gantry frame 5 through the connecting bracket 104. The rotating disk 105 is mounted below the electric cylinder 101 and moves with the telescopic movements of the electric cylinder 101. A rotary motor 106 drives the rotating disk 105 to rotate through a drive gear.

[0056] The robotic arm assembly 2 includes a flange tray assembly 201, which is connected to a rotary disk 105.

[0057] The dedicated clamping assembly 3 includes a gear bracket 301, which is mounted under the mounting plate 210. A drive gear 302 is connected to an external gear drive motor 304 and mounted on the side of the gear bracket 301 via a fixing bracket 303. A driven gear 305 is mounted on both sides of the drive gear 302 and meshes with it. An external gear 306 is mounted under the gear bracket 301 and meshes with an internal gear located inside the gear bracket 301, thereby achieving concentric rotation. A mounting box 309 is mounted outside the external gear 306 and houses a first drive gear. 307 is connected to the external first drive motor 312, and the rack 308 meshes with the first drive gear 307. Under the drive of the first drive motor 312, the first drive gear 307 drives the rack 308 to move, which drives the special clamp 311 connected to the rack 308 to perform clamping action. The reinforcing rod 310 is located below the rack 308 and is connected to the special clamp 311 to improve its structural strength. The special clamp 311 has a special clamping angle that perfectly fits the outward tilt angle of the GIS cable outlet sleeve 4, and avoids damage to the workpiece by attaching soft material to the contact surface.

[0058] The gantry frame 5 includes a column assembly 501 located on both sides, a crossbeam assembly 502 installed between the two column assemblies 501, a track moving assembly 503 installed on the crossbeam assembly 502, and a second connecting plate 504 installed on the track moving assembly 503.

[0059] The column assembly 501 includes a mounting sleeve 5012, which is located on the top side of the three-section telescopic column 5011 and cooperates with the third mounting plate 5024. The first mounting hole 5013 is located below the mounting sleeve 5012 and cooperates with the second mounting hole 5025. The reinforcing rib 5014 is located on the side of the three-section telescopic column 5011, and the mounting base plate 5015 is located below the three-section telescopic column 5011.

[0060] The crossbeam assembly 502 includes an upper and lower moving rail 5022, which is installed above the crossbeam 5023. A moving rack 5021 is installed between the upper and lower moving rails 5022. A third mounting plate 5024 is located on both sides of the crossbeam 5023. A second mounting hole 5025 is located below both sides of the crossbeam 5023.

[0061] The track moving assembly 503 includes a second drive motor 5031, which is mounted on the mounting base plate 5032 and connected to a second drive gear 5034. The second moving slider 5033 is mounted below the mounting base plate 5032 and cooperates with the moving tracks in the column assembly 501 and the beam assembly 502.

[0062] The AGV transfer module 6 includes an emergency button 601, which is installed at the rear of the vehicle body. The status display screen 602 displays the status of the entire device. The load-bearing vehicle body 603 bears the weight of the device and contains a large-capacity lithium battery to power the entire device. Tracked wheels 604 are installed around the load-bearing vehicle body 603. The AGV transfer module 6 enables the entire device to move.

[0063] The working principle of the GIS outgoing bushing disassembly and assembly equipment is as follows:

[0064] like Figure 10 As shown, the column assembly 501 is lowered and moved to a suitable position via the AGV transfer module 6. Then, the crossbeam assembly 502 is installed from top to bottom. The third mounting plate 5024 and the mounting sleeve 5012 are mated and connected, and then the first mounting fixing hole 5013 and the second mounting fixing hole 5025 are connected using pins. This completes the rapid installation of the crossbeam assembly 502.

[0065] like Figure 11 As shown, the track-moving assembly 503 achieves left-right movement on the crossbeam assembly 502 and up-down extension / retraction on the column assembly 501 via a drive gear and rack. The lifting electric cylinder assembly 1 drives the lower component to move up and down via its extension / retraction movement. The mounting plate 210 extends / retracts, driving the lower component to move and connect. The special clamping assembly 3 drives the GIS cable outlet sleeve 4 to rotate concentrically. The AGV moving module 6 drives the entire equipment to move.

[0066] like Figure 12 As shown, the lifting cylinder assembly 1 drives the rotating disk 105 to rotate via the rotary motor 106, thereby causing the lower component to rotate. The robotic arm assembly 2 swings the GIS cable outlet sleeve 4 held below by means of a swing angle. The mounting plate 210 can extend and retract along the angle of the robotic arm, thereby causing the GIS cable outlet sleeve 4 to extend and retract.

[0067] like Figure 13 As shown, the external gear drive motor 304 drives the active gear 302 and the driven gear 305 to make the clamping part rotate concentrically, and the first drive motor 312 drives the first drive gear 307 to make the rack 308 extend and retract, thereby completing the clamping action of the special clamping component 3.

[0068] The process of using GIS outgoing bushing disassembly and assembly equipment

[0069] First, such as Figure 14 The GIS outgoing bushing disassembly and assembly equipment shown can be driven directly to the working position. Due to the use of tracked wheels, it is suitable for most terrains. If a height restriction is encountered, the column can be lowered to reduce the height. If the height is still insufficient, the components can be disassembled, passed through the restriction area, and then reassembled.

[0070] After the GIS cable outlet sleeve 4 is ready, the crossbeam assembly 502 is lowered to a height where the special clamping assembly 3 can clamp it using the remote-controlled track moving component 503. The GIS cable outlet sleeve 4 is then firmly clamped by the remote-controlled robotic arm assembly 2 and the special clamping assembly 3. Next, the GIS cable outlet sleeve 4 is raised to a certain height using the remote-controlled track moving component 503. At this point, the angle sensor in the robotic arm assembly 2 provides feedback on the angle of the robotic arm. The angle of the GIS cable outlet sleeve 4 is now consistent with the angle of the robotic arm assembly 2. The angle of the GIS cable outlet sleeve 4 is adjusted to the installation angle using the installation position. Then, the flange circles are aligned by remotely controlling the left and right lateral movement on the crossbeam assembly 502 and the lifting cylinder assembly 101. The GIS cable outlet sleeve 4 is then docked by remotely controlling the forward extension and retraction movement of the mounting plate 210. When the two flange surfaces are close to a certain distance, the special clamping assembly 3 is first operated to perform a concentric rotation to align the bolt holes on the two flange surfaces, and then the docking movement continues. After docking is completed, the bolts are tightened. Loosen the special clamping component 3 to complete the installation.

[0071] The process of disassembling the GIS outgoing bushing 4 is the reverse of its installation process.

[0072] This invention employs a gantry structure with a crossbeam width of 3.6m and a column height of 2-5m. An AGV (Automated Guided Vehicle) trolley is installed below the column. This trolley uses tracked wheels and operates in a linkage manner, enabling it to drive the gantry structure to move back and forth and rotate. When passing through certain height restrictions, the column height can be lowered or the equipment can be disassembled or assembled, thereby achieving the purpose of entering the working position. Moreover, this device has multiple degrees of freedom of movement in vertical and horizontal directions, and can accurately adjust the angle of the cable outlet sleeve to ensure the installation angle and installation quality of the GIS cable outlet sleeve.

[0073] 2. This invention adopts an innovative solution of installing an automated robotic arm on a gantry crane and using a dedicated clamp, which can perfectly fit and rigidly clamp the GIS outgoing bushing. By adjusting the angle of the robotic arm, the GIS outgoing bushing can be easily positioned at various installation angles. The docking process uses a servo electric cylinder, which improves the reliability and accuracy of alignment and avoids various defects such as bumps and angle changes caused by the natural swaying of the sling. This meets the product assembly process requirements and improves the product assembly quality. At the same time, due to the use of rigid clamping, shaking during the installation process is avoided, and no other accessories are needed for support, greatly improving safety.

[0074] 3. This invention uses lithium batteries as the main power source. The equipment will not pollute the GIS disassembly and assembly environment during self-propelled movement and disassembly. The bottom movement is carried out by AGV trolleys with tracked wheels. The movement is diversified. Special clamps automatically hold the equipment. It is equipped with a remote control operating system and has a high degree of automation, which greatly reduces the labor intensity of the installation personnel.

[0075] 4. The present invention has a simple structure and relatively complete functions. It can disassemble and assemble GIS outgoing bushings, and its production cost is lower than that of other large-scale mechanical equipment, making it cost-effective.
