Description

Technical Field

[0001] This invention belongs to the field of power engineering construction and heavy equipment installation technology, specifically relating to an indoor or substation transfer system and operation method for high-voltage electrical equipment (such as GIS) in substations. Background Technology

[0002] Gas-insulated metal-enclosed switchgear (GIS) is a core piece of equipment in modern substations, boasting advantages such as compact structure, high reliability, and small footprint. During substation construction or equipment maintenance, it is often necessary to relocate or transport GIS bays at 110kV, 220kV, or even higher voltage levels over short distances. These devices are typically enormous in size and weight (up to tens of tons), and require extremely high levels of levelness and stability; any impact or tilting can damage their delicate internal insulation structure and arc-extinguishing components.

[0003] Currently, the transfer of GIS (Gas Insulated Metal Enclosed Switchgear) equipment within substations generally relies on a combination of traditional manual and simple mechanical methods, which presents several challenges: 1. Poor ground adaptability: The ground inside the substation is mostly paved with gravel. Traditional methods require clearing the gravel from the transport path in advance and laying sleepers and channel steel as temporary tracks. The preparation work is cumbersome, damages the environment inside the station, and the accuracy of track laying directly affects the stability of transportation.

[0004] 2. Low level of automation and low efficiency: It mainly relies on hydraulic jacks for lifting equipment, with manual assistance from winches to move the equipment base on the channel steel track. The whole process requires the cooperation of many people, and work must be stopped after moving a small distance to repeatedly calibrate the equipment with a level to check for any deviation. The operation is slow and extremely time-consuming.

[0005] 3. Conflict between safety risks and control precision: Manual operation of the winch makes it difficult to guarantee synchronization, which can easily lead to the equipment base "biting" or getting stuck, posing a risk of equipment overturning. To control deviation, safety must be sacrificed for extremely low efficiency.

[0006] 4. Not friendly to equipment foundation: The equipment is usually installed on a concrete base about 150mm high. Traditional methods rely entirely on the synchronous lifting and lowering of multiple jacks when the equipment is detached from and positioned on the base. This is difficult to operate and there is a risk of stress concentration or falling of the equipment due to asynchrony.

[0007] Therefore, there is an urgent need for a dedicated GIS transport system and operation method that can adapt to complex terrain, integrate lifting, load-bearing, and walking functions, achieve stable, efficient, and automated transport, and accurately align equipment foundations. Summary of the Invention

[0008] The purpose of this invention is to provide a split-type transfer system and operation method for substation GIS equipment. This system and operation method can achieve high efficiency, safety, and precise alignment of the equipment foundation.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is a split-type transfer system for substation GIS equipment, characterized in that it includes a transport bracket module, a lifting and centering module, and a tracked vehicle carrying module; when in use, the GIS chassis of the GIS equipment is placed on the transport bracket 1; The transport bracket module includes: (1) Transport bracket 1: The transport bracket is a frame structure, and the shape of the upper frame of the transport bracket matches the support structure of the lower part of the GIS chassis 4 of the GIS equipment. (2) Pressure plate 5: There are 4 pressure plates 5, which are located at the four corners of the transport bracket. The pressure plates 5 are detachably connected to the upper edge of the transport bracket 1 by bolts. (3) Roller 16 or slider, roller frame 17: Multiple rollers 16 or multiple sliders are installed on roller frame 17; there are 4 roller frames 17, and the 4 roller frames 17 are respectively fixed on the lower outer side of the 4 columns 8 of the lifting and centering module. The lifting and centering module includes: (1) Column 8: There are 4 columns, and the 4 columns are vertically fixed at the four corners of the transport bracket 1; (2) Lifting arm 6: There are 4 lifting arms, and the 4 lifting arms are arranged symmetrically in two groups. Each group can include two lifting arms on the left and right. One end of the lifting arm 6 is connected to the upper end of the column 8 by a hinge or bearing. (3) Threaded strut 7: There are 2 threaded struts. The front set of lifting arms 6 is connected by 1 threaded strut, and the rear set of lifting arms 6 is connected by another threaded strut. The tracked vehicle load-bearing module includes: (1) Tracked vehicle 9: There are two tracked vehicles, arranged one in front of the other; (2) Lifting and fixing frame 10: Two lifting and fixing frames 10 are fixedly installed on the upper part of the body of each tracked vehicle. The two lifting and fixing frames 10 are arranged in the left and right positions. The lifting and fixing frame is a gate-shaped structure. The guide groove 20 is opened on the inner vertical rod of the gate-shaped structure along the height direction. (3) Lifting machine 13: There are 4 lifting machines 13. The lifting machines 13 are fixedly installed on the upper crossbar of the lifting frame 10 of the tracked vehicle 9. The lifting end of the lifting machine 13 is equipped with a support block 14, and the support block is provided with a support groove. The support block 14 is located below the corresponding lifting arm 6. (4) Long pin 19: A long pin 19 is inserted on the roller frame 17. When in use, one end of the long pin 19 passes through the guide groove 20 on the lifting fixing frame 10.

[0010] Furthermore, it also includes an electrical control module, which includes a control box 11, either built into the tracked vehicle 9 or held independently by hand.

[0011] Furthermore, the transport bracket 1 also includes a connecting rod 2, with the connecting rod 2 fixed to the front and rear sides of the transport bracket 1 respectively.

[0012] Furthermore, the roller frame 17 is connected to the connecting frame 18 by two pins 15, and the connecting frame 18 is fixed to the lower end of the column 8 of the lifting and centering module.

[0013] Furthermore, the threaded support rod 7 is a screw with both positive and negative threads, with the middle part being the driving part and the left and right sections of the thread rotating in opposite directions.

[0014] Furthermore, the lifting platform 13 is an electrically or hydraulically driven scissor lift, screw lift, or sleeve lift mechanism.

[0015] A method for the separate transfer of substation GIS equipment based on the above system, characterized by the following steps: 1. Installation of Equipment Fixing and Lifting Centering Module: Arrange 4 synchronous jacks next to the GIS equipment 3 to lift both sides of the GIS chassis 4, so that the equipment is slightly off the ground; push the transport bracket 1 under the GIS chassis 4; lower the jacks so that the GIS chassis 4 sits on the transport bracket 1; fix the GIS chassis 4 to the transport bracket 1 with the pressure plate 5 and bolts; install the column 8, lifting arm 6, threaded support rod 7 and roller frame 17 to form a rigid lifting centering frame; 2. Self-propelled carrier docking: Two tracked vehicles 9 are remotely driven to the front and rear positions of the transport bracket 1, and the lifting and fixing frame 10 on the tracked vehicle 9 is horizontally connected to the roller frame 17 through the long pin shaft 19. 3. Integrated lifting and ground lifting: The lift 13 on the tracked vehicle 9 is remotely operated to raise its support block 14 and lift the lifting arm 6, thereby simultaneously lifting the transport bracket 1 and the GIS equipment 3 fixed on it off the ground. 4. Smooth transfer: The remotely operated tracked vehicle 9 carries the GIS equipment 3 and travels on the original road surface of the substation until it is directly above the foundation of the target equipment; 5. Precise positioning and separation: The remote-controlled lifting platform 13 descends synchronously, allowing the GIS equipment 3 and its chassis 4 to be smoothly placed on the target foundation; then, the lifting platform 13 is operated to disengage the support block 14 from the lifting arm 6, disconnect the long pin shaft 19, and remotely drive away from the tracked vehicle 9. 6. System disassembly: Use external synchronous jacks to lift GIS equipment 3, remove transport bracket 1, complete the final positioning of the equipment, and dismantle the transport bracket module and the lifting and centering module.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Revolutionary improvement in work efficiency: Transforming intermittent operations that traditionally required hours and relied on a large amount of manpower into continuous, mechanized operations that can be completed in tens of minutes. Eliminating the need for road clearing and track laying, and removing the repeated process of leveling, efficiency is expected to increase by over 300%.

[0017] 2. Significantly enhanced safety and reliability: Remote control operation via the tracked vehicle enables "human-machine separation," ensuring personnel safety. The rigid centering mechanism composed of the lifting arm and threaded struts fundamentally solves the risks of off-center loading and tilting during lifting and transportation, protecting the valuable GIS equipment.

[0018] 3. Ground adaptability and environmental friendliness: The tracked walking mechanism can travel directly on gravel roads and slightly uneven ground without any destructive construction work on the site environment, which reflects the concept of green construction.

[0019] 4. Precise and easy operation: Remote control operation allows for precise fine-tuning of movement, steering, lifting, and lowering, making it easy to align the equipment precisely with the foundation position and ensuring high-quality installation.

[0020] 5. Strong system versatility and scalability: The transport bracket can be modularly designed according to the chassis specifications of different GIS manufacturers. By selecting tracked vehicles with larger tonnage, it can meet the transportation needs of large power equipment such as GIS and main transformers with different voltage levels and weights.

Detailed Implementation

[0030] like Figure 1-8 As shown, a split-type transfer system for substation GIS equipment mainly includes a transport bracket module, a lifting and centering module, a tracked vehicle carrying module, and an electrical control module; when in use, the GIS chassis of the GIS equipment is placed on the transport bracket 1.

[0031] 1. Transport bracket module, including: (1) Transport bracket 1: The transport bracket is a frame structure; as the core load-bearing platform of the system, the transport bracket is a high-strength steel frame structure. The shape of the upper frame of the transport bracket matches the support structure under the GIS chassis 4 of the GIS equipment, and is used to directly support the entire weight of the GIS equipment 3.

[0032] (2) Pressure plate 5 and connecting rod 2: There are 4 pressure plates 5, which are located at the four corners of the transport bracket. The pressure plates 5 are detachably connected to the upper edge of the transport bracket 1 by bolts (both the pressure plates and the transport bracket have screw holes and are detachably connected by bolts). After the GIS chassis 4 is placed on the transport bracket 1, the pressure plates 5 are used to press the flanges or channel steel of the GIS chassis 4, thereby rigidly fixing the GIS equipment 3 and the transport bracket 1 into a whole and preventing relative displacement during the transfer process.

[0033] The front and rear sides of transport tray 1 (for ease of description) Figure 3 The left side is the front, the right side is the back, the top is the left, and the bottom is the right. Each of these is fixed with a connecting rod 2, which is used to enhance the structure or assist in traction.

[0034] (3) Rollers 16 or sliders, roller frames 17: Multiple rollers 16 or multiple sliders (2-10 in total, 2 in this embodiment) are installed on roller frames 17; there are 4 roller frames 17, which are respectively fixed on the outer side of the lower end of the 4 columns 8 of the lifting and centering module (i.e.: the roller frame 17 installed on the column located at the right front is located on the right side of the column; the roller frame 17 installed on the column located at the right rear is located on the right side of the column; the roller frame 17 installed on the column located at the left front is located on the left side of the column; the roller frame 17 installed on the column located at the left rear is located on the left side of the column; such as Figure 3 (As shown); multiple rollers 16 or multiple sliders facilitate pushing it under the GIS chassis with jacks in the initial stage.

[0035] Furthermore, the roller frame 17 is connected to the connecting frame 18 by two pins 15 (the roller frame 17 can be removed by pulling out the pins 15), and the connecting frame 18 is fixed to the lower end of the column 8 of the lifting and centering module.

[0036] 2. Lifting and centering module, including: (1) Column 8: There are 4 columns, and the 4 columns are vertically fixed at the four corners of the transport bracket 1.

[0037] (2) Lifting arm 6: There are 4 lifting arms, and the 4 lifting arms are arranged symmetrically in two groups. Each group can include two lifting arms on the left and right. One end of the lifting arm 6 is connected to the upper end of the column 8 by a hinge or bearing, and can rotate around the connection point within a certain angle. The lower part of the free end (the other end) of the lifting arm 6 is provided with a load-bearing structure for being lifted.

[0038] (3) Threaded support rod 7: There are two threaded support rods. One threaded support rod connects the front set of lifting arms 6, and the other threaded support rod connects the rear set of lifting arms 6. Crucially, the threaded support rod 7 is a screw with both positive and negative threads. The middle part is the drive part (manual or motor driven), and the left and right threads rotate in opposite directions. When the threaded support rod 7 is rotated, it synchronously drives the left and right lifting arms 6 to expand outward or retract inward around their hinge points. When the lifting arms 6 are lifted by external force, the threaded support rod 7 acts as a rigid connecting rod, ensuring that the lifting arms on both sides are subjected to uniform force and move synchronously, thereby ensuring that the lifted transport bracket 1 and GIS equipment 3 remain horizontal and do not tilt due to uneven loading.

[0039] 3. Tracked vehicle load-bearing module, including: (1) Tracked vehicle 9: The tracked vehicle is a remote-controlled self-propelled tracked chassis (including track connecting frame 12), which has good ground adaptability, load-bearing capacity and mobility. The number of tracked vehicles is two (the number of tracked vehicles can be configured with multiple vehicles according to the load, or it can be one; for ease of description, Figure 3 , Figure 6The left side is front, the right side is back, the top is left, and the bottom is right; in this application, two units are arranged in a front-to-back configuration, which represents the forward and reverse directions of the tracked vehicle.

[0040] (2) Lifting and fixing frame 10: Two lifting and fixing frames 10 are fixedly installed on the upper part of the body of each tracked vehicle. The two lifting and fixing frames 10 are arranged in the left and right positions. The lifting and fixing frame is a gate-shaped structure. The guide groove 20 is opened on the inner vertical rod of the gate-shaped structure along the height direction.

[0041] (3) Lifting machine 13: There are 4 lifting machines 13. The lifting machines 13 are fixedly installed on the upper crossbar of the lifting frame 10 of the tracked vehicle 9. The lifting end of the lifting machine 13 is equipped with a support block 14. The support block is provided with a support groove (when lifting, the corresponding lifting arm can be located in the corresponding support groove). The support block 14 is located below the corresponding lifting arm 6 (the lifting block 14 can lift the lifting arm 6 when it rises). The lifting machine 13 is preferably an electric or hydraulically driven scissor lift, screw lift, or sleeve lift mechanism.

[0042] (4) Long pin 19: A long pin 19 is inserted into the roller frame 17 (two long pins 19 are used in this embodiment, and corresponding long pin insertion holes are opened on the roller frame 17). When in use, one end of the long pin 19 passes through the guide groove 20 on the lifting fixing frame 10 (for positioning and guiding). It is used to insert into the guide groove 20 of the lifting fixing frame 10 and the corresponding long pin insertion hole on the roller frame 17 after the tracked vehicle 9 has traveled to the designated position below the transport bracket 1, so that the tracked vehicle 9 and the transport bracket 1 are temporarily rigidly connected in the horizontal direction, so that the two become a whole in the subsequent lifting and transfer process, and prevent relative sliding.

[0043] When the support block 14 is lifted, the lifting arm 6 is raised, and the column 8 rises accordingly. The column 8 is connected to the roller frame 17 through the pin 15, so the roller frame 17 will also rise. The long pin shaft 19 fixed on the roller frame 17 will also rise. Moreover, the long pin shaft 19 moves up and down in the guide groove 20. When the roller frame 17 and the lifting fixed frame 10 move relative to each other, the roller 16 on the roller frame 17 plays an auxiliary role.

[0044] 4. Electrical control module: (1) Control Box 11: The control box is built into the tracked vehicle 9 (the control box 11 is installed on the upper crossbar of the portal structure) or is held independently by hand. The control box includes a controller, a wireless receiver, a motor driver, a power supply, etc. The wireless receiver receives instructions from the remote control. It is used to receive instructions from the remote control to control the tracked vehicle 9 to move forward, backward, turn, and stop, as well as to control the lifting platform 13 to rise, fall, and stop. It can realize independent control of a single unit or synchronous linkage control of multiple units.

[0045] A method for the separate transfer of substation GIS equipment based on the above system includes the following steps: 1. Installation of Equipment Fixing and Lifting Centering Module: Arrange 4 synchronous jacks next to the GIS equipment 3 to lift both sides of the GIS chassis 4, so that the equipment is slightly off the ground; push the transport bracket 1 under the GIS chassis 4; lower the jacks so that the GIS chassis 4 sits on the transport bracket 1; fix the GIS chassis 4 to the transport bracket 1 with the pressure plate 5 and bolts; install the column 8, lifting arm 6, threaded support rod 7 and roller frame 17 to form a rigid lifting centering frame; 2. Self-propelled carrier docking: Two tracked vehicles 9 are remotely driven to the front and rear positions of the transport bracket 1, and the lifting and fixing frame 10 on the tracked vehicle 9 is horizontally connected to the roller frame 17 through the long pin shaft 19. 3. Integrated lifting and ground lifting: The lift 13 on the tracked vehicle 9 is remotely operated to raise its support block 14 and lift the lifting arm 6, thereby simultaneously lifting the transport bracket 1 and the GIS equipment 3 fixed on it off the ground. 4. Smooth transport: The remote-controlled tracked vehicle 9 carrying the GIS equipment 3 travels on the original road surface (such as a gravel road) of the substation until it is directly above the foundation of the target equipment; 5. Precise positioning and separation: The remote-controlled lifting platform 13 descends synchronously, allowing the GIS equipment 3 and its chassis 4 to be smoothly placed on the target foundation; then, the lifting platform 13 is operated to disengage the support block 14 from the lifting arm 6, disconnect the long pin shaft 19, and remotely drive away from the tracked vehicle 9. 6. System disassembly: Use external synchronous jacks to lift GIS equipment 3, remove transport bracket 1, complete the final positioning of the equipment, and dismantle the transport bracket module and the lifting and centering module.

[0046] Working principle and dynamic process: 1. Initial Lifting and Bracket Positioning: Arrange four synchronous jacks next to the GIS equipment 3 to lift both sides of the GIS chassis 4, slightly raising the equipment off the ground. Push the transport bracket 1 directly under the GIS chassis 4. Lower the jacks so that the GIS chassis 4 sits on the transport bracket 1. Secure the GIS chassis 4 to the transport bracket 1 using the pressure plate 5 and bolts.

[0047] 2. Install the lifting and centering mechanism: Install the four columns 8 into the preset positions of the transport bracket 1. Assemble the lifting arm 6, threaded support rod 7, and roller frame 17 to form a rigid centering frame.

[0048] 3. Tracked vehicle docking: Remotely operate two tracked vehicles 9, one in front of the other, to drive into the GIS equipment from both sides until the lifting and fixing frame 10 is aligned with the column 8, and insert the long pin shaft 19 for horizontal connection. At this time, the support block 14 on the tracked vehicle 9 should be directly below the free end of the lifting arm 6.

[0049] 4. Lifting and Load Bearing: By jogging the control box 11, all four lifting platforms 13 (front and rear) are simultaneously lifted, causing the support block 14 to contact and lift the lifting arm 6. Lifting continues until the transport bracket 1 and the GIS equipment 3 are completely off the ground. During this process, the threaded support rod 7 ensures that the left and right lifting arms 6 move synchronously, ensuring stable lifting.

[0050] 5. Transfer and movement: The two tracked vehicles 9 are remotely controlled to move forward slowly and synchronously, smoothly transporting the GIS equipment 3 to the target equipment foundation.

[0051] 6. Lowering and Positioning: After the transport is in place, operate the lifting platform 13 to lower slowly and synchronously, so that the transport bracket 1 touches the ground and the GIS chassis 4 is accurately placed on the foundation. After the support block 14 disengages from the lifting arm 6, it returns to its original position. Pull out the long pin shaft 19, and the tracked vehicle 9 drives away.

[0052] 7. Disassembly and Restoration: Use synchronous jacks to lift the GIS chassis 4 again, remove the transport bracket 1, and lower the jacks to fully position the equipment. Remove components such as the pressure plate 5, lifting arm 6, and column 8. The operation is complete.

[0053] The core concepts of this invention are modular integration, adaptive leveling, tracked movement, and remote control operation. Specific highlights are as follows: 1. Full-process mechanization and remote control operation: The system integrates a dedicated transport bracket, a self-propelled tracked transport vehicle, and a lifting and centering mechanism. The entire process of lifting, carrying, transferring, and lowering the equipment can be completed through ground remote control, realizing "separation of man and machine", which greatly reduces labor intensity and safety risks and improves work efficiency.

[0054] 2. Adaptive lifting and rigid connection centering mechanism: The innovative lifting arm-threaded strut mechanism adopts a positive and negative thread design to ensure that the lifting arms on both sides rise and fall synchronously. It forms a rigid connection during the lifting process, and the force is balanced. It effectively avoids the swaying and asynchronous problems caused by traditional flexible lifting (such as steel wire rope), and greatly ensures the stability of the transferred equipment (GIS).

[0055] 3. Tracked chassis adapts to complex terrain: Using a remote-controlled tracked vehicle as the power carrier, its tracks have low ground pressure and strong grip, enabling it to drive directly on the gravel road surface of the substation without the need for additional track laying. This "zero preparation" for the ground protects the station environment and provides excellent obstacle crossing and climbing capabilities.

[0056] 4. Integrated Lifting and Load-Bearing Conversion: The system decouples the "lifting" and "load-bearing movement" functions yet seamlessly connects them. First, an external synchronous jack (or a lifting device integrated into the system) is used to complete the initial lifting of the GIS to place it into the transport bracket. The subsequent "lifting off the ground" and "lowering back to the foundation" actions are achieved by the lift integrated into the tracked vehicle by lifting the boom on the transport bracket, making the movements precise and controllable.

[0057] 5. Precise Positioning and Smooth Placement: By remotely controlling the tracked vehicle to move slowly, GIS equipment weighing tens of tons can be easily and precisely moved to the target foundation location. Synchronous control of the lifting platform ensures the equipment descends horizontally, guaranteeing the base of the equipment sits stably on the foundation and avoiding impact.

[0058] The following alternatives can achieve the same invention objective and the same invention effect: 1. Power-driven alternative: The manual drive of the threaded support rod 7 can be replaced by a servo motor or stepper motor drive to achieve precise electric control of the unfolding angle of the lifting arm 6, and an angle sensor can be integrated to achieve automatic leveling.

[0059] 2. Alternative lifting mechanism: The mechanical centering lifting mechanism consisting of the lifting arm 6 and the threaded support rod 7 can be replaced by multiple (e.g., four) independently controlled electric or hydraulic cylinders, which directly press against specific lifting points of the transport bracket 1. Multi-point synchronous lifting control is achieved through sensor feedback, which can also achieve smooth lifting and centering.

[0060] 3. Alternative Vehicle Options: The tracked vehicle 9 can be replaced by a wheeled omnidirectional transport vehicle (AGV), a hydraulic flatbed truck, or a rail-mounted trolley. Wheeled AGVs are more suitable for flat, hardened surfaces and offer higher positioning accuracy; hydraulic flatbed trucks have a stronger load-bearing capacity; and rail-mounted trolleys are suitable for repetitive transport along fixed routes.

[0061] 4. Alternative connection methods: The mechanical connection method of the pin 15 can be replaced by an automatic locking mechanism, an electromagnetic chuck, or a hydraulic clamp to achieve rapid and automatic docking and separation of the tracked vehicle 9 and the transport bracket 1, further improving the level of automation.

[0062] 5. Alternative Control Method: The remote control can be directly controlled and upgraded to an automatic navigation system. With a pre-planned transfer route, the system can automatically control the tracked vehicle 9 to travel to the designated location and complete lifting and lowering actions, achieving highly automated and intelligent unmanned transfer.
