The bottom of the base 100 is provided with a first roller 110 to realize the moving function. Exemplarily, two groups are arranged at intervals in the length direction of the base 100, and each group includes two first rollers 110; in order to facilitate the steering, at least one group of first rollers 110 is a universal wheel; in particular, at least one first roller 110 has a brake function to realize the brake stop function of the base 100. The first support platform 200 is arranged on the base 100 and is arranged to be able to rise or fall in the vertical direction; the second support platform 300 is arranged on the first support platform 200 and is arranged to be able to move into or out of the first support platform 200 in the horizontal first direction; wherein, the second support platform 300 is used to support the switch trolley to be repaired.

[0026] When the switch trolley transfer and maintenance device provided by the present invention is used, the base 100 is first pushed to the position of the switch trolley of the switch cabinet, and after aligning the switch trolley, the first support platform 200 is raised to an appropriate height, and then the second support platform 300 is moved out from directly above the first support platform 200 and moved to directly below the switch trolley, and the switch trolley to be repaired is supported by the second support platform 300. The device provided by the present invention can conveniently transfer the switch trolleys one by one, reducing the labor intensity of the switching operation of the operation and maintenance personnel, while avoiding potential risks during the operation process, and ensuring the safety of the switch trolley during the transfer and maintenance operation.

[0027] In the present invention, the second support platform 300 can adopt any appropriate structural form to move into or out of the position directly above the first support platform 200 along the first horizontal direction, for example, a matching mechanism of a slide rail and a slide block can be provided between the two.

[0028] In some embodiments, a third support platform 400 is provided on the second support platform 300, and the third support platform 400 includes a support frame 410 fixed on the second support platform 300, and two auxiliary frames 420 are provided on the support frame 410, and the two auxiliary frames 420 are arranged to be able to approach or move away from each other along a horizontal second direction, and form a support surface for supporting the switch trolley to be repaired, and the second direction is perpendicular to the first direction. In an embodiment of the present invention, by further providing a third support platform 400 with an adjustable support surface size on the second support platform 300 to support the switch trolley to be repaired, the device provided by the present invention can further meet the transfer and repair requirements of switch trolleys of different widths, and improve the adaptability of the switch trolley transfer and repair device in the present invention.

[0029] It is understandable that, in the embodiment of the present invention, the two auxiliary frames 420 can adopt any appropriate structural form to achieve the goal of being close to or away from each other along the second horizontal direction. Figure 3 As shown, two electric hydraulic cylinders are arranged on the support frame 410, and the output ends of the two electric hydraulic cylinders are respectively connected to the two auxiliary frames 420, and the two auxiliary frames 420 are realized by the two electric hydraulic cylinders, thereby forming support surfaces of different sizes to support the switch trolley to be repaired.

[0030] The switch trolley transfer and maintenance device provided by the present invention is not only applicable to the KYN28 switch cabinet line outlet cabinet, but also applicable to 10kV busbar transformer cabinet, 10kV section switch and isolation cabinet.

[0031] In some embodiments, the second support platform 300 and the third support platform 400 are respectively configured to be hollowed out for the inspection of the bottom of the switch trolley. It should be noted that the bottom of the existing switch trolley mechanism is equipped with a travel switch that reflects the position of the switch trolley. The present invention sets the second support platform 300 and the third support platform 400 to be hollowed out respectively, so that the maintenance personnel can directly inspect the travel switch at the bottom of the switch trolley, thereby solving the problem that when the current switch trolley is placed in a conventional transfer trolley, the switch chassis cannot be opened and the travel switch cannot be inspected. In other words, the hollow structure design in the present invention can not only meet the inspection and maintenance of the internal mechanism of the switch trolley, but also meet the inspection of the switch position travel switch of the switch trolley chassis, thereby solving the pain point that the current conventional switch transfer trolley cannot inspect the switch trolley position travel switch.

[0032] In some embodiments, a second roller 310 is disposed at the bottom of the second support platform 300, and the second roller 310 is configured to lift up the first roller 110 when the first support platform 200 is lowered to the lowest position. Through the above configuration, when the first support platform 200 is lowered to the lowest position, the second support platform 300 can be supported by the second roller 310, thereby reducing the burden of the connection mechanism between the second support platform 300 and the first support platform 200.

[0033] In the present invention, the first support platform 200 can be realized by any appropriate form to rise or fall in the vertical direction relative to the base 100. In some embodiments of the present invention, the base 100 and the first support platform 200 are respectively provided with a first support rod 210 and a second support rod 220 that cross each other and are hinged together, the lower end of the first support rod 210 is hinged on the base 100, the upper end of the first support rod 210 is arranged to be able to translate along the first limiting groove 230 extending along the first direction of the first support platform 200, the upper end of the second support rod 220 is hinged on the first support platform 200, the lower end of the second support rod 220 is arranged to be able to translate along the second limiting groove 120 extending along the first direction of the base 100, and the base 100 or the second support platform 300 is provided with a driving source for driving the upper end of the first support rod 210 and the lower end of the second support rod 220 to translate along the first direction.

[0034] The driving source is an electric hydraulic cylinder 240 disposed on the first supporting platform 200 , the tail end of the electric hydraulic cylinder 240 is hinged on the first supporting platform 200 , and the output end of the electric hydraulic cylinder 240 is hinged on the hinge shaft 250 of the first supporting rod 210 and the second supporting rod 220 .
