Description

Technical Field

[0001] This utility model belongs to the field of transformer maintenance technology, and more specifically, it relates to a transformer maintenance device. Background Technology

[0002] As the "heart" of the power system, the transformer undertakes the core functions of power transmission and voltage transformation. Its operational reliability and stability directly maintain the stable power supply of the entire power network. During long-term uninterrupted operation, due to multiple influences such as electromagnetic loss, mechanical vibration, and environmental factors, potential hazards such as insulation aging and component wear will gradually accumulate in the transformer. Therefore, regular inspection and maintenance are required to ensure its good performance. However, when inspecting transformers, maintenance personnel often need to use maintenance equipment to climb to a height for repairs.

[0003] Based on the above, the current maintenance equipment has been found to have poor stability during use. After the maintenance equipment is raised, it is prone to slight displacement or sliding at the bottom due to external forces (such as the movement of maintenance personnel, wind, etc.), which affects the overall stability of the maintenance platform. This not only affects the normal work of maintenance personnel, but also poses certain safety hazards to maintenance personnel. Utility Model Content

[0004] To address the aforementioned technical problems, this disclosure relates to a transformer maintenance device. This device solves the issue that current maintenance devices are prone to slight displacement or sliding at the bottom due to external forces, affecting the overall stability of the maintenance platform. By incorporating a stable structure and retracting the casters, the contact area between the base and the ground is increased, lowering the center of gravity and significantly enhancing the stability of the entire device. Compared to traditional casters, which are prone to swaying and tilting under natural wind or external forces generated by maintenance personnel at high altitudes, posing significant safety hazards, this device effectively resists interference from wind and external forces generated by maintenance personnel. It provides maintenance personnel with a safe and stable working platform. Maintenance personnel can perform delicate operations such as tool retrieval and equipment testing without worrying about safety risks caused by device instability, allowing them to fully concentrate on maintenance work and improving maintenance quality and efficiency.

[0043] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0044] This utility model provides a transformer maintenance device, including: a supporting base frame 1 and a stabilizing structure 2;

[0045] The supporting base frame 1 has a movable groove 101 inside, and a reinforcing support plate 1011 is fixedly connected in the movable groove 101. The supporting base frame 1 is provided with a stabilizing structure 2, which includes the following components:

[0046] Drive motor 201: Fixedly installed on the top of the supporting base frame 1. The drive end of the drive motor 201 is fixedly connected to a lead screw 2011.

[0050] The device can be moved to the maintenance area using the casters 2032. Then, the drive motor 201 is started to rotate the lead screw 2011. The lead screw 2011 rotates and engages with the threaded hole 2021 on the moving horizontal plate 202. The moving horizontal plate 202 is guided by the guide hole 2022 at the upper limit of the guide rod 2012, so that the lead screw 2011 drives the moving horizontal plate 202 to move. The moving horizontal plate 202 then drives the limit plate 203 to rise. As a result, the limit plate 203 drives the casters 2032 to retract through the connecting base plate 2031, so that the supporting base frame 1 contacts the ground, increasing the contact area. Then, the maintenance personnel climb onto the supporting platform 205 and raise it by controlling the electric telescopic rod 2041 to raise the maintenance personnel to the transformer, and then carry out maintenance work.

[0051] Example 2: Based on Example 1, wherein, as Figures 4 to 6 As shown, the top of the bearing platform 205 is provided with a guardrail structure 3. The guardrail structure 3 includes a fixed bottom frame 301, a connecting support frame 3011 and a connecting rod 3012. The fixed bottom frame 301 is fixedly connected to the top of the bearing platform 205. The connecting support frame 3011 is fixedly connected to the four sides of the top of the fixed bottom frame 301. The connecting rod 3012 is fixedly connected between the connecting support frames 3011.

[0052] A first sliding frame 302 is fixedly connected to the top four sides of the fixed base frame 301. A second sliding frame 303 is provided between the first sliding frames 302. A screw hole 3021 is opened on the top of the first sliding frame 302, and a clamping bolt 3022 is engaged in the screw hole 3021.

[0053] The second slide frame 303 has a slot 3031 on its side and a fixing recess 304 on its outer side. A protrusion 3041 is fixedly connected to the inner side wall of the fixing recess 304. The protrusion 3041 is inserted into the slot 3031. An extension protrusion 3042 is fixedly connected to both ends of the fixing recess 304. A docking plate 3051 is provided on the opposite side of the extension protrusion 3042. A storage frame 305 is fixedly connected between the docking plates 3051. The extension protrusion 3042 and the docking plate 3051 are fastened by screws 306 and nuts 3061.

[0054] An adjustment frame 307 is provided on the inner side of the connecting support frame 3011. Sliding holes 3071 are provided at the four corners of the adjustment frame 307. A guardrail 3072 is fixedly connected to the bottom of the adjustment frame 307. The guardrail 3072 is slidably installed in the first sliding frame 302 and the second sliding frame 303. The guardrail 3072 in the first sliding frame 302 has a through groove 3073.

[0055] By loosening the four sets of clamping bolts 3022, the height of the adjustment frame 307 can be adjusted. After adjusting to the appropriate position, the clamping bolts 3022 are tightened to press the guardrail strip 3072, thus completing the adjustment. The storage frame 305 allows maintenance tools to be placed inside, so that maintenance personnel can work without carrying tools, while also preventing tools from being lost.

[0056] The specific usage and function of this embodiment are as follows:

[0057] In this invention, the device can be moved to the maintenance area via the casters 2032. Then, the drive motor 201 is started to rotate the lead screw 2011. The lead screw 2011 engages with the threaded hole 2021 on the moving horizontal plate 202. The moving horizontal plate 202 is guided by the guide hole 2022 at the upper limit of the guide rod 2012, causing the lead screw 2011 to move the moving horizontal plate 202. The moving horizontal plate 202 then causes the limiting plate 203 to rise. As a result, the limiting plate 203 retracts the casters 2032 via the connecting base plate 2031, allowing it to support the bottom frame. 1. By increasing the contact area with the ground, the center of gravity is lowered, significantly enhancing the stability of the entire device. This effectively resists interference factors such as wind and external forces generated by maintenance personnel, providing a safe and stable working platform for maintenance personnel. At the same time, maintenance personnel do not need to worry about the safety risks caused by device instability during operation, and can devote themselves to maintenance work, improving maintenance quality and efficiency. Then, maintenance personnel climb onto the bearing platform 205 and raise it by controlling the electric telescopic rod 2041 to elevate the maintenance personnel to the transformer, and then carry out maintenance work.
