Description

Technical Field

[0001] This invention relates to the field of transformers, and more particularly to a convenient transformer stand. Background Technology

[0002] In the power industry, especially in emergency power supply, grid expansion, temporary capacity increase and post-disaster reconstruction scenarios, the rapid and safe deployment of transformers is a common but challenging task.

[0003] Traditional transformer platforms and foundations are mostly fixed concrete structures, requiring a certain construction period, incurring high costs, and being immobile, thus failing to meet temporary and rapid-response power demands. While mobile transformer trolley solutions offer some flexibility, they still have many drawbacks. For example, most are based on wheeled platforms, making it difficult to deploy transformers stably and maneuverably in complex terrains such as unpaved roads, mud, snow, and water. Furthermore, they are only compatible with one type of mobility, such as wheeled or tracked transport chassis, which cannot be flexibly changed according to task requirements, resulting in low equipment utilization and the need for multiple specialized vehicles, leading to high costs. Traditional transformer deployment methods require large machinery such as cranes for installation and leveling, making operations difficult in areas with limited space or damaged infrastructure.

[0004] Therefore, current transformer stands are difficult to apply to areas where transformers need to be deployed quickly.

[0005] Therefore, a convenient transformer stand needs to be designed to solve the above problems. Summary of the Invention

[0006] To overcome the shortcomings of current transformer stands that are difficult to apply to areas requiring rapid transformer deployment, the purpose of this invention is to provide a convenient transformer stand that is widely applicable and can quickly and safely deploy transformers.

[0012] Preferably, the limiting device includes multiple limiting frames, each fixedly connected to the upper side of the support frame. Each displacement frame has a limiting block fixedly connected to its upper side. Each limiting block has a first limiting screw screw screwed onto both its left and right sides. The first limiting screw screws are used to limit the displacement of the limiting block and the displacement frame. A second limiting screw screw is screwed onto the opposite side of each limiting block. The second limiting screw screws are used to limit the rotation of the support arm.

[0013] Preferably, the support device includes a first electric push rod, and the first electric push rod is installed at a position away from the support frame on the support arm.

Detailed Implementation

[0038] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0039] Example 1, as Figures 1-7As shown in the figure, a portable transformer platform includes a main beam 1, electric lifting columns 2, a lifting frame 3, a loading frame 4, a support frame 5, a fixing frame 6, a locking rod 7, a relay device 8, a locking device 9, a motorized device 10, an adjusting device 11, a limiting device 12 and a support device 13. The main beam 1 is of a U-shaped frame structure, and the middle part of the main beam 1 is of a horizontally placed "day" character structure. Electric lifting columns 2 are installed on both the left and right side walls of the main beam 1. The electric lifting columns 2 are all of the screw drive type with synchronous control. A lifting frame 3 is fixedly connected between the moving parts of the two electric lifting columns 2 on both sides. The middle part of the lifting frame 3 is of a horizontally placed "day" character structure. A loading frame 4 is detachably installed on the upper side of the lifting frame 3. The number and size of the loading frames 4 are not unique. The loading frame 4 is used to install a transformer. The middle part of the loading frame 4 is of a horizontally placed "day" character structure. Both the front and rear sides of the loading frame 4 are structures with multiple mounting holes, and the structures with mounting holes of the loading frame 4 extend forward and backward respectively and are in a hanging state, so that when the transformer is hoisted and installed on the loading frame 4, it is convenient to install the transformer on the mounting hole structure part of the loading frame 4 through fasteners. Both the left and right ends of the main beam 1 are fixedly connected with support frames 5. The support frame 5 is of a double-layer plate frame structure, and rectangular holes are opened in both the double-layer plate structures of the support frame 5. The lower side of the middle part of the main beam 1 is fixedly connected with a fixing frame 6. The fixing frame 6 is of a horizontally placed "day" character structure. Locking rods 7 are fixedly connected to the lower sides of the left and right parts at the front and rear positions of the fixing frame 6. The lower sides of the locking rods 7 are all structures with front-back direction positioning holes. A relay device 8 is provided below the fixing frame 6. Four locking devices 9 are provided at the relay device 8. The locking devices 9 cooperate with the adjacent locking rods 7 respectively. The locking rod 7 can be fixed in the adjacent locking device 9 through the positioning hole structure on its lower side. The relay device 8 is fixed below the locking rod 7 and the fixing frame 6 through the locking device 9. Motorized devices 10 are detachably provided on both the front and rear sides of the relay device 8. The motorized device 10 is used for traveling work. The relay device 8 and the motorized device 10 can be integrally disassembled and evacuated from the fixing frame 6 and the locking rod 7 through the locking device 9. Adjusting devices 11 and limiting devices 12 are provided at the support frames 5 respectively. A support device 13 is provided on the other side of the adjusting device 11. The adjusting device 11 is used to adjust the position of the support device 13. The limiting device 12 is used to limit and lock the position of the adjusting device 11. The support device 13 is used to lift the adjusting device 11 and a part of the main beam 1. The horizontally placed "day" character structures in the middle parts of the main beam 1, the lifting frame 3, the loading frame 4 and the fixing frame 6 are convenient for wiring and assembly operations at the bottom of the transformer.

[0040] As Figures 6-9As shown, the relay device 8 includes a relay frame 81, an extension frame 82, and a connecting frame 83. The relay frame 81 is located below the fixed frame 6. Four locking devices 9 are respectively located on the front, back, left, and right sides of the relay frame 81. The relay frame 81 is installed on the locking rod 7 through the locking devices 9. Extension frames 82 are fixedly connected to the front and back positions of the relay frame 81. Connecting frames 83 are fixedly connected to the left and right sides of the two extension frames 82. The connecting frames 83 are all structures with multiple mounting holes. The mounting hole structure of the connecting frames 83 is used for the detachable installation of the motor device 10.

[0041] like Figures 8-13 As shown, the locking device 9 includes a locking tube 91, a sliding frame 92, a locking nut 93, a locking screw 94, and a shock absorber 95. There are four locking tubes 91, which are fixedly connected to the front, rear, left, and right sides of the repeater frame 81. All four locking tubes 91 have an open top structure, and their front and rear walls each have rectangular holes. A sliding frame 92 is slidably placed inside each locking tube 91. Each sliding frame 92 has a U-shaped frame structure, with its front and rear side walls extending out of the rectangular holes in the corresponding locking tube 91. A locking nut 93 is fixedly connected to the rear side wall of each sliding frame 92's U-shaped frame structure. Each sliding frame 92's U-shaped frame structure and locking screw... Each of the four locking tubes 93 is screwed with a locking screw 94. Each sliding frame 92 is fixedly connected to the lower inner wall of the locking tube 91. The four locking tubes 91 can be moved to the bottom of each locking rod 7, so that each locking rod 7 extends into the locking tube 91 and contacts the upper side of the corresponding sliding frame 92. The corresponding locking screw 94 is then inserted from front to back into the positioning hole structure on the front wall of the sliding frame 92 and below the locking rod 7. The locking screw 94 is then screwed out from the rear wall of the sliding frame 92 and into the locking nut 93. In this way, the sliding frame 92 and the locking rod 7 can be fixed. When the motorized device 10 transports the transformer, the shock absorber 95 is used for shock absorption.

[0042] like Figure 7As shown, the mobile device 10 includes an assembly frame 101 and a motor assembly 102. An assembly frame 101 is installed at each of the connecting frames 83, and a motor assembly 102 is installed at each of the assembly frames 101. The motor assembly 102 is used for movement. The number and size of the assembly frames 101 and the motor assembly 102 are not unique. The motor assembly 102 can be a tracked unit, which can transport transformers on unpaved roads; alternatively, the motor assembly 102 can be a wheeled unit, which can quickly transport transformers in areas with better road conditions; furthermore, the motor assembly 102 can be a sled used for transporting transformers on icy and snowy roads. Mobility components such as floating boxes are used in water-bound areas; the motor unit 102 can be a non-powered traction type, in which case a traction rope is installed at the connecting frame 83 on the left or right side and the traction rope is installed at the drive machinery, such as a winch or drive vehicle; the motor unit 102 can also be a powered type, such as a gasoline engine-driven wheel set or an electric wheel hub, in which case it can be moved autonomously by personnel control; the appropriate motor unit 102 can be selected according to the situation of transporting the transformer, so as to improve the convenience of transformer transportation and deployment speed, and to be applicable to more complex areas for transformer deployment.

[0043] like Figures 14-18As shown, the adjustment device 11 includes linear rails 111, displacement frames 112, fixed shafts 113, and support arms 114. There are four linear rails 111. Each support frame 5 has a linear rail 111 fixedly connected to a rectangular hole in its double-layer plate structure. Two displacement frames 112 are slidably connected between two corresponding upper and lower linear rails 111 at each support frame 5. A fixed shaft 113 is fixedly connected between each pair of corresponding upper and lower displacement frames 112. Support arms 114 are rotatably connected to each fixed shaft 113. Each support arm 114 has multiple limiting holes on its upper side, distributed along the axis of the fixed shaft 113. Support devices 13 are respectively located on the outer side of each support arm 114. The support arms 114 can move on the linear rails 111 via the displacement frames 112, allowing the support arms 114 to move within the double-layer plate structure of the support frame 5. The support arm 114 moves within the frame structure and rotates at the fixed shaft 113, causing it to screw into the double-layer frame structure of the support frame 5. This folds and retracts the support arm 114 within the double-layer frame structure, reducing the volume of the portable transformer platform and improving its maneuverability in confined spaces. This enhances the platform's applicability and makes it more convenient for vehicle transport. Furthermore, by adjusting the position and angle of the support arm 114 at the support frame 5, the support arm 114 and support device 13 can be positioned at different locations at the transformer deployment site. This allows the support device 13 to be flexibly adjusted to contact the ground according to the ground conditions, resulting in greater stability for the portable transformer platform.

[0044] like Figures 14-18 As shown, the limiting device 12 includes a limiting frame 121, a limiting block 122, a first limiting screw 123, and a second limiting screw 124. There are two limiting frames 121, each fixedly connected to the upper side of the support frame 5. Both limiting frames 121 are frame structures, and each has multiple limiting holes on its upper side. Limiting blocks 122 are fixedly connected to the upper side of the displacement frame 112, and each limiting block 122 has a first limiting screw screw screwed onto both its left and right sides. The screw 123, the first limiting screw 123 can be screwed into the limiting hole structure at the adjacent limiting frame 121, so that the first limiting screw 123 restricts the displacement of the limiting block 122 and the displacement frame 112. The second limiting screw 124 is screwed into the limiting hole structure at the adjacent support arm 114, so that the second limiting screw 124 restricts the rotation of the support arm 114.

[0045] like Figure 14As shown, the support device 13 includes a first electric push rod 131, a pressure sensor 132, and a mounting base 133. The first electric push rod 131 is installed on the side of the support arm 114 away from the support frame 5. The first electric push rod 131 is independently controlled, vertically oriented, and its telescopic component faces downward. The lower end of the telescopic component of the first electric push rod 131 is equipped with a pressure sensor 132. The mounting base 133 is fixedly connected to the lower side of the detection surface of the pressure sensor 132. The mounting base 133 is a square hollow flange structure. The mounting base 133 is used to install the ground contact panel. The ground contact panel installed at the mounting base 133 can be selected according to the environment in which the transformer is deployed, such as: a cone structure that can be inserted into the soil, a large-area flat plate structure that can expand the contact area and has higher stability, or a high platform structure for water-crossing roads and icy roads.

[0046] like Figure 19 As shown, it also includes an evacuation device 14, which includes a second electric push rod 141, an evacuation frame 142, and evacuation wheel sets 143. The evacuation device 14 is located below the relay frame 81 and is used to quickly and easily evacuate the relay device 8, locking device 9, and motorized device 10 from under the fixed frame 6. The second electric push rod 141 is installed in the middle of the relay frame 81, with the moving part of the second electric push rod 141 facing downward. The lower end of the moving part of the second electric push rod 141 is fixedly connected to the evacuation frame 142, and evacuation wheel sets 143 are installed on all four sides of the evacuation frame 142. When the unit 102 is a sled or tracked vehicle that cannot be evacuated from under the fixed frame 6 in a forward or backward direction, the locking screw 94 can be unscrewed first, and then the portable transformer platform can be lifted as a whole by the support device 13, so that the motor unit 102 is lifted off the ground. At this time, the second electric push rod 141 can be activated, so that the moving part of the second electric push rod 141 drives the evacuation frame 142 and the evacuation wheel set 143 to move downward, so that the evacuation wheel set 143 contacts the ground. Then, the relay device 8, the locking device 9 and the motor unit 10 can be quickly and conveniently evacuated from under the fixed frame 6 by the forward and backward movement of the evacuation wheel set 143.

[0047] Example 2, as Figures 1-19As shown, this portable transformer stand is prepared in advance for transformer deployment: when a transformer needs to be temporarily deployed in a certain area, a suitable motor unit 102 can be selected and installed on the connecting frame 83 via the assembly frame 101 according to the road conditions of the transportation route of the area where the transformer needs to be deployed; a suitable ground contact panel can be selected and installed on the mounting base 133 according to the ground conditions of the area where the transformer needs to be deployed; the support arm 114 is folded and retracted into the double-layer frame structure of the support frame 5 to reduce the volume of the portable transformer stand; according to the specifications of the transformer to be deployed, a suitable loading frame 4 is selected and installed on the lifting frame 3, then the transformer is hoisted to the loading frame 4 and installed through the mounting holes of the loading frame 4, which extends to the front and rear sides to the suspended state.

[0048] Based on the aforementioned "preparations for transformer deployment using this portable transformer platform," in an example addressing different deployment areas: when the area where the transformer needs to be deployed has a fully paved road surface, the locking screw 94 can be unscrewed from the locking tube 91 and locking nut 93, allowing the locking rod 7 to be disassembled from the locking tube 91. This enables the relay device 8, locking device 9, and motorized device 10 to be disassembled from the fixed frame 6. At this point, the transformer can be hoisted onto the loading frame 4, and the main beam 1, adjusting device 11, limiting device 12, and supporting device 13 can be hoisted onto the transport vehicle as a whole. The portable transformer platform, with the relay device 8, locking device 9, and motor device 10 removed, is transported by a transport vehicle to the transformer deployment area. If the area where the transformer needs to be deployed has an unpaved road surface, or if the transport vehicle has difficulty transporting the portable transformer platform to the transformer deployment area due to road conditions such as post-disaster roads, or if the area where the transformer needs to be deployed is an area that requires temporary power supply, the portable transformer platform can be transported as a whole by a transport vehicle to the end of the road, and then the portable transformer platform can be moved to the deployment area by the motor device 10.

[0049] Deployment of the portable transformer stand to the transformer: After the portable transformer stand transports the transformer to the required deployment area, four support arms 114 can be pulled out from the double-layer frame structure of the support frame 5 to expand the support device 13 outward. Then, the first limit screw 123 is screwed into the limit hole structure of the limit frame 121, and the second limit screw 124 is screwed into the limit hole of the support arm 114. If the ground in the area where the transformer needs to be deployed is uneven, the position and angle of the support arm 114 at the support frame 5 can also be adjusted, and then fixed through the first limit screw 123 and the second limit screw 124. Subsequently, the four first electric push rods 131 are activated, causing the four first electric push rods 131 to drive the pressure sensor 132 and the mounting seat 133 to move downward, so that the ground contact panel installed at the mounting seat 133 contacts the deployed ground. Through the expanded support arm 114 and the mounting seat 133, the ground contact panel can expand the support area of the portable transformer stand, making the transformer installed on the portable transformer stand more stable. After the mounting seat 133 contacts the ground with the ground contact panel, the value of the pressure sensor 132 can be used to determine that the portable transformer stand is supported by the support arm 114 and the mounting seat 133. At this time, the relay device 8, the locking device 9, and the mobile device 10 do not provide support for the portable transformer stand. At this time, the locking screw 94 can be unscrewed, and the support device 13 can be controlled to continue operating, causing the locking rod 7 to move upward and disengage from the locking tube 91, so that the locking rod 7 is disassembled from the locking tube 91, thereby disassembling the relay device 8, the locking device 9, and the mobile device 10 from the fixed frame 6, and withdrawing the relay device 8, the locking device 9, and the mobile device 10 from the deployment area and protecting them to avoid the relay device 8, the locking device 9, and the mobile device 10 being affected by rain, snow, wind, or mud in the external environment. When the deployed transformer needs to be withdrawn from the deployment area, the relay device 8, the locking device 9, and the mobile device 10 can be quickly put in place without cleaning and maintenance operations. When the deployed transformer needs to be evacuated, only the relay device 8, the locking device 9, and the mobile device 10 need to be moved under the relay frame 81, so that the locking rod 7 is reconnected to the locking tube 91, and the locking screw 94 is screwed in to re-assemble. By using the method of sleeving the locking rod 7 in the locking tube 91, the relay device 8 and the mobile device 10 can be quickly docked with the locking rod 7 and the fixed frame 6 through the locking device 9 for rapid transfer of the transformer. Then, the electric lifting column 2 can be activated, causing the moving part of the electric lifting column 2 to drive the lifting frame 3 and the loading frame 4 to move upward, thereby driving the transformer at the loading frame 4 to move upward so that the transformer is at the assembly height. Then, wiring and assembly operations can be performed on the bottom of the transformer through the middle "day" - shaped structure of the main beam 1, the lifting frame 3, the loading frame 4, and the fixed frame 6.

[0050] The motor unit 102 of the mobile device 10 is not a fixed component and can be a track, wheel, or sled, etc. It can be selected and installed according to the road conditions along the way from the warehouse to the deployment area. Through modular design, it can be used for multiple purposes. One main platform can be adapted to multiple modes of mobility, which improves the adaptability of the portable transformer platform to different mission scenarios, such as urban emergency, field operation, disaster relief or snow and ice environment. During long-distance road transportation, the support arm 114 can be stored in the double-layer structure of the support frame 5. At the same time, the mobile device 10 can also be disassembled, which reduces the size of the entire portable transformer platform, making it convenient to be transported by standard truck and reducing transportation costs. After arriving in areas with bad road conditions, the mobile device 10 suitable for the local terrain can be quickly installed to achieve autonomous travel for the last mile.

[0051] If the ground in the deployment area is uneven, the pressure values ​​of the four pressure sensors 132 will differ. Feedback from the four pressure sensors 132 can be used to individually fine-tune the extension length of each first electric push rod 131 until the pressures of the four pressure sensors 132 reach equilibrium. This process can be controlled manually or fully automated by integrating an automatic leveling algorithm. This method allows for rapid leveling of the transformer.
