Description

Technical Field

[0001] This application relates to the field of mobile GIS combined electrical appliances, specifically to a GIS intelligent installation and alignment trolley. 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. Since the last century, the rapid development of the power industry and the continuous increase in transmission voltage levels have led to large-scale inter-regional power grid interconnections, placing high demands on the reliability of power transmission and distribution equipment. 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 only 10% to 30% of traditional AIS substations. This is a significant advantage for land-scarce urban, mountainous, and underground substation applications. GIS (Gas Insulated Switchgear) systems occupy an important position in power transmission and transformation systems due to their advantages such as small footprint, strong environmental adaptability, high reliability, convenient installation, and low maintenance workload. However, because GIS equipment has high environmental requirements during installation and disassembly, and despite the protection of the metal casing, outdoor installations are still significantly affected by wind, rain, and extreme weather, thus the installation of GIS equipment has gradually shifted from outdoor to indoor. However, there are many inconveniences in the alignment and installation of GIS equipment within the installation workshop (Note: This invention mainly solves the problem of moving and aligning two GIS bay units within the installation workshop). Currently, the main problems are as follows:

[0003] Movement within the installation workshop 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. Furthermore, the weight of the basic unit of the GIS switchgear is generally over 3 tons, and ordinary conventional equipment simply cannot bear such a large load. Therefore, it is extremely inconvenient to move the GIS switchgear inside the installation workshop.

[0005] Existing methods of movement cannot achieve precise displacement.

[0006] Most existing methods of moving GIS switchgear involve lifting it from the bottom before moving it. However, these methods involve lifting the base unit a considerable distance. After the base unit is moved to the installation position, it needs to be docked. The docking requirements between the base units of GIS switchgear are high, and excessive lifting will prevent the docking operation from being performed. At the same time, the docking between the units requires small and precise displacement. Therefore, there is a need for a device that can make precise small-distance adjustments after the GIS switchgear is moved to the installation position without requiring a large lift from the bottom.

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

[0008] Current operating methods still rely on manual movement. 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 move it to the installation position. Alternatively, a small tank is placed under the middle of the GIS electrical unit's base frame, and then a forklift is inserted at both ends, with manual labor pulling the forklift to transport the foundation unit to the installation position for alignment. Both of these methods suffer from low efficiency, high manpower consumption, difficulty in precisely controlling displacement, and a tendency to damage the floor.

[0009] Most existing operating methods generate vibrations, which may cause damage to the internal components of the equipment.

[0010] Currently, methods such as laying rollers (or steel plates) and moving the equipment manually or using small tanks placed under the base frame cannot avoid the problem of equipment vibration and swaying caused by uneven ground. If there is strong vibration and swaying, it is difficult to avoid damage and collisions to the internal parts of the equipment. Therefore, alignment tools with higher stability are needed. Summary of the Invention

[0011] The purpose of this application is to provide a GIS intelligent installation alignment trolley to solve the problem of inconvenient installation alignment and movement between two adjacent interval units in the installation workshop during the indoor installation of GIS.

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

[0013] This application provides a GIS intelligent installation and alignment trolley, including a support bracket, an electric lift, a Y-axis lead screw transmission mechanism, and an X-axis lead screw transmission mechanism. The support bracket is connected to the C-shaped channel steel at the bottom of the GIS spacer unit. The electric lift is driven by its own motor to lift and lower the support bracket. The Y-axis lead screw transmission mechanism drives the lead screw through the motor to move the support bracket on the lead screw, so that the weight on the support bracket moves synchronously and achieves precise displacement. The X-axis lead screw transmission mechanism performs precise movement in the X-axis direction.

[0014] The support bracket includes a lifting mechanism slot and a T-shaped slot. The lifting mechanism slot is used in conjunction with an electric lifting mechanism, and the T-shaped slot is used in conjunction with a Y-axis lead screw transmission mechanism.

[0015] The electric lifting platform includes a lifting head and a drive motor. The lifting head and the lifting platform slot cooperate with each other to increase the force-bearing area while preventing it from falling out. The drive motor can control the lifting head to perform small-amplitude and precise lifting.

[0016] The Y-axis lead screw transmission mechanism includes a T-shaped rigid rail and a transmission connecting pad. The T-shaped rigid rail and the T-shaped slot cooperate with each other to prevent the support bracket from tilting or coming off after being loaded. The transmission connecting pad moves in the Y-axis direction along the direction of the lead screw through the transmission of the lead screw, so that the weight carried above it moves synchronously in the Y-axis direction. The transmission connecting pad has a slot at the bottom, which cooperates with the X-axis lead screw transmission mechanism, so that it can move on the X-axis lead screw transmission mechanism. The Y-axis lead screw transmission mechanism also includes a fixed support frame.

[0017] The X-axis lead screw transmission mechanism includes an X-axis lead screw transmission mechanism base frame, a dovetail platform, a power socket, a spring-loaded universal ball wheel, and support feet. The X-axis lead screw transmission mechanism base frame moves along the X-axis via the lead screw transmission on it. The dovetail platform enhances the load-bearing capacity while ensuring smooth movement of the X-axis lead screw transmission mechanism base frame above it. The power socket supplies power to the motor. The spring-loaded universal ball wheel has an internal spring structure. When the spring-loaded universal ball wheel is subjected to less pressure, it contacts the ground first compared to the support feet, providing support for the entire structure. With less friction with the ground, the entire structure can be manually pushed. When the spring-loaded universal ball wheel is subjected to greater pressure, its internal spring is compressed, causing the wheel to retract inwards. At this point, the support feet contact the ground, and the entire structure is stably placed on the ground.

[0018] The GIS intelligent installation alignment trolley also includes an intelligent alignment device installed on the GIS bay unit. The intelligent alignment device includes a signal transmitter, a fixing plate, and a fixing plunger. The signal transmitter emits a linear infrared laser signal, which is received by the signal receiving target and reflected back to itself, transmitting positioning coordinate data to align the relative positions. When the laser signal shines on the area around the crosshair center of the signal receiving target, it reflects back a normal signal, indicating that the position is not accurately aligned. When the laser signal shines on the crosshair center of the signal receiving target, it reflects back a special signal and emits a prompt sound, indicating that the position is accurately aligned. At this time, the GIS bays have completed precise alignment. The fixing plate is pressed against the side of the GIS cylinder flange by passing corresponding screws through the threaded holes on its plate. The diameter of the fixing plunger matches the hole on the GIS cylinder flange. After being inserted into the hole, it works together with the corresponding screws passing through the fixing plate to fix the intelligent alignment device. The two together play a fixing role to prevent the device from loosening and detaching during operation.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Solve the problem of inconvenient alignment and movement between two adjacent bay units in the installation workshop during the indoor installation of GIS.

[0021] This invention employs an electric drive screw, driven by a motor, and an electric lift to raise the GIS interval, thereby allowing the load on the transmission connection pad block integrated with the screw to move synchronously.

[0022] 2. Solved the problem that existing operating methods could not achieve precise alignment.

[0023] This invention uses a lead screw drive mechanism to precisely move GIS spacer units. First, the GIS base unit is moved to the installation position. Then, the motor is remotely controlled to determine the height and relative position of the GIS spacer unit on the X and Y axes. Finally, an infrared laser position sensor is used to further determine the position, thereby solving the problem of precise docking of GIS base units.

[0024] 3. Improved installation efficiency and reduced labor intensity for workers.

[0025] With this invention, operators only need to place the electric lift on the screw drive mechanism and then place the support bracket on the electric lift, and then move and align it by controlling the motor. Operation is simple, significantly reducing manual labor, lowering labor intensity, shortening the time for moving GIS interval units, and allowing for direct and precise docking without needing to lower the GIS base unit first—a one-step process. The number of operators can also be greatly reduced, saving human resources.

[0026] 4. Reduces requirements for the installation environment and equipment relocation costs.

[0027] This invention integrates mobility and positioning, enabling the lifting and movement of GIS foundation units without the need for hoisting equipment. This significantly reduces the requirements for the GIS foundation unit movement environment, eliminating the need for overhead cranes on indoor roofs and reducing construction costs for the movement environment. Compared to renting hydraulic flatbed trucks and hoisting equipment, this invention has lower manufacturing costs and can be used repeatedly over extended periods.

[0028] 5. This invention has versatility for other complex devices.

[0029] In addition to GIS basic unit equipment, this invention can also lift and move other types of equipment, such as goods and small vehicles, in relatively narrow indoor environments, demonstrating high versatility. Attached Figure Description

[0043] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0044] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0045] like Figures 1 to 9 As shown in the figure, this application provides a GIS intelligent installation and alignment trolley, including a support bracket 1, an electric lift 2, a Y-axis lead screw transmission mechanism 3, and an X-axis lead screw transmission mechanism 4. The support bracket 1 is connected to the C-shaped channel steel at the bottom of the GIS spacer unit. The electric lift 2 is driven by its own motor to lift and lower the support bracket 1. The Y-axis lead screw transmission mechanism 3 drives the lead screw through the motor to make the support bracket 1 on the lead screw move together, so that the weight on the support bracket 1 moves synchronously and achieves the purpose of precise displacement. The X-axis lead screw transmission mechanism 4 performs precise movement in the X-axis direction.

[0046] The support bracket 1 includes a lifting mechanism slot 11 and a T-shaped slot 12. The lifting mechanism slot 11 is engaged with the electric lifting mechanism 2, and the T-shaped slot 12 is engaged with the Y-axis lead screw transmission mechanism 3.

[0047] The electric lifting platform 2 includes a lifting head 21 and a drive motor 22. The lifting head 21 cooperates with the lifting platform slot 11 to increase the force-bearing area while preventing it from coming off. The drive motor 22 can control the lifting head 21 to perform small-amplitude precise lifting.

[0048] The Y-axis lead screw transmission mechanism 3 includes a T-shaped rigid rail 31 and a transmission connecting pad 32. The T-shaped rigid rail 31 and the T-shaped slot 12 cooperate with each other. When these components are tightly fitted, they can prevent the support bracket 1 from tilting or falling out under load, thus improving the safety and reliability of the equipment. The transmission connecting pad 32 can move in the Y-axis direction along the direction of the lead screw through the transmission of the lead screw, so that the weight carried above it can move synchronously in the Y-axis direction. It has a slot at the bottom to cooperate with the X-axis lead screw transmission mechanism 4, allowing it to move on the X-axis lead screw transmission mechanism 4. The fixed support frame 33 mainly serves to fix the lead screw, support the lead screw, and connect the motor.

[0049] The X-axis lead screw transmission mechanism 4 includes an X-axis lead screw transmission mechanism base frame 41, a dovetail platform, a power socket, a spring-loaded universal steel ball wheel, and a support pad. The Y-axis lead screw transmission mechanism base frame 41 can move along the X-axis via the lead screw transmission on it. The special structure of the dovetail platform 42 can enhance the load-bearing capacity while ensuring smooth movement of the upper Y-axis lead screw transmission mechanism 3 base frame. The power socket 43 supplies power to the motor. The spring-loaded universal steel ball wheel 44 has an internal spring structure. When it is subjected to less pressure, its ball wheel contacts the ground first compared to the support pad 45, and the ball wheel provides support for the entire structure. The friction with the ground is small, and the entire structure can be pushed manually. When it is subjected to greater pressure, its internal spring is compressed, and the ball wheel retracts inward. At this time, the support pad 45 contacts the ground, and the entire structure is stably placed on the ground.

[0050] The GIS intelligent installation alignment trolley also includes an intelligent alignment device 6 installed on the GIS bay unit. The intelligent alignment device 6 includes a signal transmitter, a fixing plate, and a fixing plunger. The signal transmitter emits a linear infrared laser signal, which is received by the signal receiving target and reflected back to itself, transmitting positioning coordinate data to align the relative positions. When the laser signal shines on the area around the cross center of the signal receiving target, it reflects back a normal signal, indicating that the position is not accurately aligned. When the laser signal shines on the cross center of the signal receiving target, it reflects back a special signal and emits a prompt sound, indicating that the position is accurately aligned. At this time, the GIS bays have been accurately aligned. The fixing plate is pressed against the side of the GIS cylinder flange by passing corresponding screws through the threaded holes on its plate. The diameter of the fixing plunger matches the hole on the GIS cylinder flange. After being inserted into the hole, it and the corresponding screw passing through the fixing plate together fix the intelligent alignment device, which plays a fixing role and prevents the device from loosening and detaching during operation.

[0051] like Figure 7 , Figures 10-12The intelligent alignment device 6 includes a signal transmitter 601. The signal transmitter 601 emits a linear infrared laser signal, which is received by the signal receiving target 604 and reflected back to itself, transmitting positioning coordinate data to align the relative positions. When the laser signal illuminates the area around the crosshair center of the signal receiving target, it reflects back a normal signal, indicating that the position is not accurately aligned. When the laser signal illuminates the crosshair center of the signal receiving target, it reflects back a special signal and emits a prompt sound, indicating that the position is accurately aligned, at which point the GIS intervals 5 have been accurately aligned. A fixing plate 602 is used, with corresponding screws passing through the threaded holes on the plate and pressing it against the side of the GIS cylinder flange. A fixing plunger 603 has a diameter that matches the hole on the GIS cylinder flange (clearance tolerance 0.1mm). After being inserted into the hole, it, together with the corresponding screws passing through the fixing plate, fixes the intelligent alignment device, and the two together serve to fix it, preventing the device from loosening and detaching during operation.

[0052] After all mechanisms are assembled, the support bracket 1 is connected to the GIS equipment via the C-shaped steel channel at the bottom of the GIS. The GIS equipment is then raised to a suitable height using an electric lifting platform 2. Wireless remote control of the Y-axis lead screw drive mechanism 3 and X-axis lead screw drive mechanism 4 causes the GIS bay units to translate in the X and Y axes. When the cylinders of two GIS bays are precisely aligned, the signal transmitter should be aligned with the center of the signal receiving target crosshair and emit a prompt sound, indicating that the GIS bays have completed precise docking.

[0053] This invention employs a small, mobile device that is compact in size and can be easily placed and brought into GIS installation workshops. It has the ability to work in confined indoor environments, making it suitable for both indoor and outdoor operations, and has a wide range of applications.

[0054] The GIS equipment is lifted using a small electric lift, making the entire lifting process more convenient, simplifying the work process, and improving installation efficiency. Furthermore, its accompanying support bracket is compatible with various models of GIS equipment, demonstrating its versatility.

[0055] Its innovative use of a screw drive mechanism combined with a small electric lift and support bracket makes it suitable for various models of GIS equipment, giving it a certain degree of versatility.

[0056] The system employs an infrared laser emitter to align the cylinders of the GIS spacer unit, making the alignment more precise and eliminating the need for manual assistance in determining the relative positions. This improves work efficiency while ensuring accuracy.

[0057] Due to its unique structural design, this invention can be used not only for moving GIS equipment but also for small-scale movement of other complex equipment, demonstrating versatility in many aspects and solving the problem of inconvenient equipment movement in other confined environments.

[0058] This invention is highly automated, saves time and effort, and is more likely to be favored by users.

[0059] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
