Description

Technical Field

[0001] This application relates to the field of GIS transportation, specifically to a multifunctional GIS transportation device. Background Technology

[0002] Gas-Insulated Switchgear (GIS) is a high-performance, high-voltage power transmission and distribution equipment widely used in substations. It is a compact unit that seals all primary equipment in a substation (excluding transformers), including circuit breakers, disconnectors, grounding switches, voltage transformers, current transformers, surge arresters, busbars, connectors, and outgoing terminals, within a grounded metal casing filled with pressurized SF6 (sulfur hexafluoride) gas as insulation and arc-quenching medium. Compared to open-type substations (AIS), GIS, due to its superior SF6 gas insulation, significantly shortens the insulation distance, resulting in a size and footprint that is only 10% to 30% of that of traditional AIS substations. GIS switches occupy an important position in power transmission and distribution systems due to their advantages such as small footprint, strong environmental adaptability, high reliability, convenient installation, and low maintenance. Because GIS equipment has high environmental requirements during installation and disassembly, and despite the protection of a metal casing, outdoor installation is still significantly affected by wind, rain, and extreme weather, thus the installation of GIS equipment is gradually shifting from outdoor to indoor. However, there are many inconveniences in installing and transporting GIS equipment within the installation workshop. Currently, the main problems are as follows:

[0003] Transportation within the installation plant is inconvenient.

[0004] Because the space inside the installation workshop is extremely limited compared to the outside, such as the height restrictions of the entrance and exit gates and the height restrictions of the internal ceiling, large lifting equipment simply cannot enter the workshop to carry out operations. Moreover, the weight of the basic unit of GIS switchgear is generally more than 3 tons, and ordinary conventional equipment simply cannot bear such a large load. Therefore, the transportation of GIS switchgear inside the installation workshop is extremely inconvenient.

[0005] Existing transportation methods cannot achieve precise displacement.

[0006] Existing transportation methods mostly involve lifting the GIS (Gas Insulated Switchgear) unit from its base before transport. However, because these methods involve lifting the base unit a considerable distance, it's necessary to connect it to the installation location after transport. Since the connection requirements between GIS base units are high, excessive lifting can prevent this connection work. Therefore, a device is needed that can transport GIS units to the installation location without requiring significant lifting from the bottom.

[0007] The existing work methods are labor-intensive, time-consuming, and labor-intensive for the workers.

[0008] Current operational methods still rely on manual transportation. For example, this involves laying rollers (thick-walled steel pipes) or sliding plates (steel plates) on the road surface, then using manual labor to pry open the base frame of the GIS foundation unit to slowly transport it to the installation location. Alternatively, a small tank is placed under the base frame of the GIS electrical unit, and then a forklift is inserted at both ends, with manual labor pulling the forklift to move the foundation unit to the installation location. Both of these methods suffer from low efficiency, high manpower consumption, difficulty in control, and a tendency to damage the floor.

[0009] Currently, most power grid GIS equipment is installed in sections on a channel steel base frame, which is directly grounded without gaps. According to relevant data and on-site installation surveys, the main methods for indoor handling of GIS equipment include overhead cranes, laying ground tracks, manual rollers, and using air cushions or transport tanks. Due to the high construction and maintenance costs of indoor overhead cranes and ground tracks, and the influence of project costs, dedicated overhead cranes and ground tracks for GIS equipment handling are generally not built. The manual roller method requires placing rollers under the equipment and manually pushing and pulling, which is labor-intensive and has low safety. A better method is to use air cushions or transport tanks. First, the GIS equipment needs to be lifted to at least 15cm off the ground using jacks or lifting devices. Then, the air cushion or transport tank is placed in the support position under the equipment. Once both ends of the equipment are stably placed on the transport device, the handling process begins. Upon positioning, the equipment still needs to be supported by jacks or lifting devices, removed from the transport device, and then placed on the ground. Alternatively, a hydraulic flatbed truck can be used. First, hoisting equipment is used to lift the GIS equipment off the ground at a considerable height. Then, the GIS equipment is hoisted onto the hydraulic flatbed truck. The truck is moved to the working position, and then a crane is used to lift the GIS equipment, remove it from the truck, and lower it down. Sometimes, jacks are needed to assist in the handling process, and the direction and position of the handling devices need to be adjusted. These methods mostly employ a combination of active and passive handling, cannot achieve omnidirectional movement, the turning radius is affected by the length of the equipment, resulting in poor flexibility. They also require a high degree of ground flatness, have long handling times, and cannot simultaneously achieve precise movement and alignment between GIS equipment. Summary of the Invention

[0010] The purpose of this application is to provide a multifunctional GIS transportation device that enables rapid installation and maintenance of GIS equipment, can be adaptively adjusted according to different GIS installation and usage environments, and can be used multiple times, thus having strong versatility.

[0011] To achieve the above objectives, this application provides the following technical solution:

[0012] This application provides a multi-functional GIS transportation device, including a multi-purpose lifting device, a channel steel base frame, and a magnetic trolley.

[0013] The multi-purpose lifting device is installed above the channel steel base frame to lift the channel steel base frame;

[0014] The channel steel base frame is installed on the multi-purpose lifting device to support the GIS basic bay unit;

[0016] The multi-purpose lifting device includes a reinforcing bracket, a piston rod protection groove, a piston rod hydraulic cylinder, a motor protective housing, a control panel, drive wheels, a sliding screw hole docking fixture, and a load-bearing plate. Two sets of drive wheels are provided, with a load-bearing plate installed between them. The motor protective housing is installed above the drive wheels, and a control panel is mounted on the motor protective housing. A piston rod hydraulic cylinder is also installed on the top of the motor protective housing, with its top extending into the piston rod protection groove. The load-bearing plate is equipped with a sliding screw hole docking fixture for fastening to the channel steel base frame and a reinforcing bracket for increasing the strength of the load-bearing plate.

[0017] The piston rod type hydraulic cylinder includes a hydraulic cylinder body, a piston rod is provided at the top of the hydraulic cylinder body, the piston rod extends into the piston rod protection groove, and the hydraulic cylinder body is also provided with a hydraulic oil inlet and outlet.

[0018] The motor protective housing is provided with a hydraulic cylinder fixing groove, which cooperates with the piston rod type hydraulic cylinder to prevent the hydraulic cylinder from slipping during use. The motor protective housing is also provided with a power supply battery pack.

[0019] The drive wheel includes a rotary drive motor and a travel drive motor. When the rotary drive motor receives a signal and is powered, it controls the rotary motor drive gear to rotate. The rotary motor drive gear drives the rotary motor driven gear to rotate through gear meshing. The rotary motor driven gear and its lower transmission rod are integrated. After the transmission rod rotates, it drives the gear conveyor belt for belt drive. The gear conveyor belt drives the main wheel connected to the chassis to rotate. When the travel drive motor receives a signal and is powered, it drives the travel motor drive gear to rotate. The travel motor drive gear drives the travel motor driven gear to rotate through gear meshing. The travel motor driven gear drives the travel motor driven auxiliary gear to rotate through gear meshing. The travel motor driven auxiliary gear drives the main wheel drive gear to rotate through gear meshing, thus enabling the bottom main wheel to complete the rotation and travel action.

[0020] The slidable screw hole docking fixture includes a screw hole docking fixture, a universal screw hole, a slidable stud, and a load-bearing block. The slidable stud has coarse threads at both ends connecting the screw hole docking fixture and the load-bearing block, and its surface is smoothed to allow it to move within the grooves of the load-bearing plate. The screw hole docking fixture and the load-bearing block move synchronously with the slidable stud to achieve a fit with the slots of the channel steel base frame and to clamp the edge of the channel steel. The load-bearing plate is provided with reinforcing bracket slots; inserting the reinforcing bracket into these slots increases the overall strength of the load-bearing plate. To reduce deformation under heavy loads and improve reliability, the load-bearing plate is also provided with a sliding groove, in which the sliding stud can move to move the screw hole docking fixture to the appropriate position to correspond to different models of channel steel base frames. The positioning screw holes on the load-bearing plate are matched with universal screw holes and tightened simultaneously with screws and nuts. After simultaneous tightening, the screw hole docking fixture and the load-bearing plate can be moved synchronously. Different hole positions are provided to match various models of channel steel base frames. The main body of the load-bearing plate serves to connect the two side structures and bear the load.

[0021] The magnetic trolley includes a trolley on which a power supply box, a pressure pump, and a strong magnetic block are installed. The power supply box provides power to the battery pack, drive motor, or other equipment; the pressure pump supplies pressure to the piston rod type hydraulic cylinder; the trolley has flexible casters at the bottom, which enable it to move the equipment flexibly; the strong magnetic block is equipped with a strong magnetic switch handle. When the strong magnetic block approaches the channel steel base frame, adjusting the strong magnetic switch handle generates a strong magnetic attraction to the channel steel base frame, causing the trolley to move synchronously with the channel steel base frame.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention employs a small transport device, which is compact in size and can be easily placed and brought into the GIS installation plant. It has the ability to work in narrow indoor environments, and is suitable for both indoor and outdoor operations, with a wide range of applications.

[0024] The innovative fastening method using tooling bolts at both ends makes the entire transportation process more convenient, eliminating the need to remove the device from the bottom, simplifying the operation process, improving installation efficiency, and its innovative chute structure is applicable to various types of GIS foundation unit channel steel base frames.

[0025] The lifting method adopted is hydraulic cylinder lifting, which has a high upper limit on lifting weight and meets the basic requirements for lifting GIS foundation units.

[0026] It adopts an innovative solution that integrates protection, remote control and power supply, which enables remote control over small movements, enhancing personnel safety; the carried battery pack reduces the power supply requirements of the site.

[0027] The drive wheel module uses a hub motor for stepless speed regulation, resulting in more precise and reliable movement.

[0028] Two solutions were adopted to enhance the reliability of the equipment: a reinforced support and a piston rod protection groove. These solutions ensured the reliability of the equipment when bearing heavy loads, improved its anti-deformation ability, and thus significantly reduced safety hazards during equipment operation.

[0029] 7. An innovative solution of a magnetic suction trolley integrating pressure supply and power supply was adopted, which improved the convenience of transporting pressure supply and power supply equipment, reduced equipment transportation costs, and realized the functions of pressure supply and power supply and synchronous transport of channel steel base frame.

[0054] Working principle:

[0055] The sliding bolt hole docking fixture can move in the grooves on the load-bearing plate to accommodate various types of channel steel base frames; the hydraulic cylinder can raise and lower the piston rod by adjusting the input hydraulic pressure to lift the load-bearing plate. Simultaneously, the electric drive wheels can achieve rotation, forward and backward movement by adjusting the rotary drive motor and the travel drive motor.

[0056] Place the load-bearing plate body on the channel steel base frame that needs to be lifted to the matching position. Then, place the load-bearing block from the bottom of the load-bearing plate body upwards, pressing it against the groove edge of the channel steel base frame. Next, install the sliding screw hole docking fixture, sliding it through the slide groove to the appropriate position, and then tighten the universal screw holes and positioning screw holes with bolts. Next, install the motor protective shell, battery power pack, remote control, and manual control panel. Then, connect the rotary drive motor and the travel drive motor to the remote control, manual control panel, and battery power pack through the power and signal input ports. Figure 5 The central motor and drive wheel are installed inside the motor protective housing and secured with bolts, completing the overall installation. At this point, by adjusting the input hydraulic pressure, the piston rod in the hydraulic cylinder is raised into the piston rod protective groove, allowing the sliding bolt-hole mating fixture and the channel steel base frame, which is secured to the load-bearing plate, to be raised synchronously. Then, through manual control or wireless remote control and the manual control panel, the motor drive wheel can be rotated, moved forward and backward, etc., allowing the multi-functional base frame clamping and lifting device to move forward, backward, and rotate synchronously with the clamped channel steel base frame.
