The trolley placement groove 122 is installed on the top of the platform frame 121 through a plurality of adjustable lifting components 124.
[0046] In specific implementation, the platform frame 121 can be constructed of steel components to form a supporting frame structure, the trolley placement slot 122 can be a pair of angle steel components arranged opposite to each other, and the circuit breaker trolley 23 is placed between the two angle steel components and supported on the two angle steel components. In this way, the movable maintenance platform 12 can be specifically suitable for carrying the corresponding circuit breaker trolley 23, which is convenient for smoothly and safely transporting the circuit breaker trolley 23 between the prefabricated cabin 21 and the maintenance cabin 11.
[0047] Each adjustable lifting assembly 124 of the embodiment of the present invention includes a lifting stud 1241 fixed with an operating wheel 1242, one end of the lifting stud 1241 is fixedly connected to the trolley placement slot 122, and the other end of the lifting stud 1241 is spirally connected to the platform frame 121 for vertical lifting.
[0048] In an embodiment of the present invention, the switch cabinet 22 is connected to the circuit breaker trolley 23 through a quick plug-in mechanism. Exemplarily, the quick plug-in mechanism of the embodiment of the present invention may include a sliding member, a guide member, and an anti-mis-insertion quick-connect member; the sliding member further includes a guide rail provided on the switch cabinet 22 and a roller or a slider provided on the circuit breaker trolley 23, and the roller or the slider is slidably matched with the guide rail; the guide member further includes a tapered guide column provided on the switch cabinet 22 and a V-shaped guide groove provided on the circuit breaker trolley 23, and the V-shaped guide groove is slidably matched with the tapered guide column; the anti-mis-insertion quick-connect member further includes an asymmetric plug-in assembly provided between the switch cabinet 22 and the circuit breaker trolley 23.
[0049] The use of the quick plug-in mechanism can ensure that the circuit breaker trolley 23 can be safely, quickly and efficiently pulled out without disassembling other components, thereby avoiding additional damage to the equipment.
[0050] The sliding member and the guide member are arranged in coordination to guide the circuit breaker trolley 23 to approach or move away from the switch cabinet 22 in a directional, efficient and accurate manner; more specifically, the guide rails can be made of high-strength aluminum alloy or galvanized steel guide rails, and the surface is hardened to reduce the friction coefficient to ensure that the circuit breaker trolley 23 slides in smoothly; and self-correction is achieved through rollers or sliders, and the deviation tolerance can reach ±2mm.
[0051] The anti-mis-insertion quick-connect component is provided to prevent mis-insertion of different types of equipment. More specifically, the asymmetric plug-in assembly can use an asymmetric slot connector or a coding key connector. For example, the asymmetric slot connector can be a triangular and circular combined positioning pin and pin hole respectively provided on the circuit breaker trolley 23 and the switch cabinet 22.
[0052] In the embodiment of the present invention, refer to Figure 4 and Figure 5 The mobile transport ramp 13 includes a ramp body 131 provided with a height adjustment component 132 , and a second lockable universal wheel 133 is provided at the bottom of the ramp body 131 .
[0053] Furthermore, the height adjustment assembly 132 of the embodiment of the present invention may include a plurality of lead screw and nut transmission components arranged in the longitudinal direction, and the plurality of lead screw and nut transmission components are connected by a synchronization component to achieve synchronous lifting and lowering.
[0054] Exemplarily, the height adjustment assembly 132 has at least two lead screw and nut transmission components, and the two ends of the lead screw of each lead screw and nut transmission component are respectively connected between the angles of the ramp body 131 and are vertical.

The lead screw can preferably adopt a trapezoidal or ball screw with precision grade C7 to achieve a stroke accuracy of ±1mm; specifically, the synchronization component can link multiple lead screws through a synchronization shaft or chain to ensure that the two sides of the ramp are lifted and lowered synchronously and the deviation is ≤2mm.
[0055] More specifically, the ramp body 131 may include a ramp frame and a ramp panel; the ramp frame is preferably made of high-strength steel and the surface is rust-proofed; the ramp panel is preferably made of an aluminum alloy plate with an anti-slip texture, which has the advantages of reducing deadweight while ensuring the safety of personnel and equipment. The overall size of the ramp body 131 is designed according to the actual situation of the prefabricated cabin 21 to meet the needs of equipment transportation.
[0056] In order to achieve an adjustable inclination angle of the ramp panel to adapt to the prefabricated cabin 21 or the maintenance cabin 11 with different height differences, the ramp frame is a movable structure, that is, the lower end of the ramp frame corresponding to the ramp panel is rotatably connected, and the high end of the ramp frame corresponding to the ramp panel is connected through a height adjustment component 132. The height adjustment component 132 can be raised and lowered manually or electrically to achieve the purpose of changing the inclination angle of the ramp panel on the ramp frame, and has stronger applicability.
[0057] Furthermore, a second lockable universal wheel 133 may be provided at each of the four bottom corners of the ramp body 131 to facilitate the movement of the entire ramp body 131 at any time and to lock and fix it during transportation to prevent it from sliding or tilting, thereby ensuring the safety and stability of transportation.
[0058] When in use, first determine the vertical distance between the bottom surface of the prefabricated cabin 21 or the inspection cabin 11 and the outdoor ground, then adjust the slope height of the mobile transport ramp 13 through the height adjustment component 132, so that the highest point of the slope is flush with the ground of the prefabricated cabin 21 or the inspection cabin 11, ensuring that the circuit breaker trolley 23 and other equipment can pass smoothly, and then use the second lockable universal wheel 133 to push the mobile transport ramp 13 to the specified position and fix it. When the original prefabricated cabin 21 or the inspection cabin 11 itself is equipped with a fixed outdoor step, it can also be replaced with a movable step, which is convenient for timely replacement according to different uses. For example, when the circuit breaker trolley 23 is to be transported out, the movable step is directly replaced with the mobile transport ramp 13.
[0059] The movable maintenance system 1 of the embodiment of the present invention can realize the flexible transfer of equipment such as circuit breaker trolley 23 from the prefabricated cabin 21 or the maintenance cabin 11 by setting up a mobile transport ramp 13, which not only greatly improves the maintenance efficiency, but also effectively solves the problem that there is a height difference between the prefabricated cabin 21 or the maintenance cabin 11 and the outdoor connection, and the mobile platform for transporting the circuit breaker trolley 23 cannot enter and exit the cabin body, thereby improving the convenience and safety of power equipment maintenance work. At the same time, it has good versatility and adaptability, and is expected to become one of the indispensable auxiliary tools in the power industry.
[0060] An embodiment of the present invention also provides a movable maintenance method for prefabricated cabin type switchgear equipment. Based on the above-mentioned movable maintenance system 1, the movable maintenance method includes using a movable maintenance platform 12 and a movable transport ramp 13 to transfer the circuit breaker trolley 23 between the prefabricated cabin 21 and the maintenance cabin 11, and performing comprehensive maintenance work in the maintenance cabin 11.
[0061] In an embodiment of the present invention, the movable maintenance method includes the following specific steps:
[0062] Disassembling the circuit breaker trolley 23 in the prefabricated cabin 21;
[0063] Use the movable maintenance platform 12 to carry and transport the circuit breaker trolley 23 to the maintenance cabin 11;
[0064] Complete the maintenance and repair work of the circuit breaker trolley 23 in the maintenance cabin 11;
[0065] The movable maintenance platform 12 is then used to carry and transport the circuit breaker trolley 23 to the prefabricated cabin 21 , and the circuit breaker trolley 23 is assembled to the switch cabinet 22 .
[0066] Reference Figure 1 In specific implementation, when the circuit breaker trolley 23 needs to be inspected or repaired in detail, the quick plug-in mechanism on the switch cabinet 22 is operated to smoothly pull the circuit breaker trolley 23 out of the switch cabinet 22 and place it on the movable maintenance platform 12. Then, the circuit breaker trolley 23 is safely transported to the maintenance cabin 11 through the transfer channel using the movable maintenance platform 12 for efficient and safe maintenance operations. After the maintenance is completed, the circuit breaker trolley 23 is transported back to the prefabricated cabin 21 in the reverse steps, reinstalled in the switch cabinet 22, and necessary functional tests are performed to finally restore its normal function.
