[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1-5 The present invention provides the following two preferred embodiments:

[0024] Example 1: A special installation tool for voltage transformers, comprising: a lifting plate 3, which is fixedly mounted on the output end wall of a hydraulic cylinder 2, the hydraulic cylinder 2 being fixedly mounted on a base 1; first sliding grooves 4 symmetrically formed on both side walls of the lifting plate 3; and a baffle 5 fixedly mounted on the lifting plate 3; a guide rail 6, which is connected to the lifting plate 3 via a connecting assembly and an auxiliary assembly; a bracket 7 fixedly mounted at the bottom of the guide rail 6; second sliding grooves 8 symmetrically formed on both side walls of the guide rail 6; and sliders fixedly mounted on the inner walls of both sides of a U-shaped tray 9, the sliders being movably engaged within the first sliding groove 4 and the second sliding groove 8; slots 10 symmetrically formed on the side walls of the connecting assembly; and a protruding plate 11 fixedly mounted at the bottom of the lifting plate 3, the guide rail 6 engaging with the protruding plate 11. A slot 12 is provided on the convex plate 11. The two side walls of the baffle 13 are fixedly connected to the side walls of the slot 12. The insert plate 14 is symmetrically fixed on the side wall of the guide rail 6 and is inserted into the slot 10. A square groove 15 is provided on the side wall of the guide rail 6. A movable groove 16 is provided on the two side walls of the square groove 15. The two ends of the fixed column 17 are fixedly connected to the side wall of the movable groove 16. The fixed column 17 is sleeved with the first spring 18. The locking block 19 is movably locked in the square groove 15. The locking block 19 is locked in the slot 12 and the baffle 13. A movable plate 20 is fixedly provided on the two side walls of the locking block 19. The movable plate 20 is movably locked in the movable groove 16. A round hole 21 is provided on the movable plate 20. The round hole 21 is sleeved with the fixed column 17 and the movable plate 20 is locked in the first spring 18.

[0025] In use, insert plate 14 is inserted into slot 10. During the process, after the inclined surface of the locking block 19 contacts the baffle 13, the locking block 19 moves upward along the square groove 15 as the insert plate 14 moves along the slot 10. The moving plate 20 compresses the first spring 18 until the inclined surface of the locking block 19 separates from the baffle 13. The first spring 18 resets and pushes the moving plate 20 to move along the moving groove 16, so that the locking block 19 engages with the slot 12 and the baffle 13. At this time, the guide rail 6 engages with the protruding plate 11 to complete the fixed connection between the guide rail 6 and the lifting plate 3. The operation is simple and does not require tools. Then, the voltage transformer is placed on the U-shaped tray 9. The sliders on both sides of the inner wall of the U-shaped tray 9 slide from the second slide groove 8 to the first slide groove 4, and the U-shaped tray 9 is moved to the lifting plate 3 to engage with the baffle 5. Then, the guide rail 6 and the lifting plate 3 are disassembled, and the hydraulic cylinder 2 is started to move the voltage transformer on the U-shaped tray 9 to the installation position.

[0026] Example 2: Based on Example 1, the auxiliary component has a rotating shaft 23 fixedly installed on both ends of the pulley 22. The rotating shaft 23 is rotatably connected to the side wall of the square groove 15. The winding reel 24 is rotatably installed on the guide rail 6. The traction rope 25 is fixedly installed on the side wall of the locking block 19. The other end of the traction rope 25 is fixedly connected to the winding reel 24 after passing around the pulley 22. The protrusions 26 are symmetrically fixedly installed on both sides of the protrusion plate 11. The protrusions 26 have a slot 27. A limiting plate 28 is movably locked in the slot 27. A second spring 29 is installed on the side end of the limiting plate 28. The limiting block 30 is fixedly installed on the side wall of the limiting plate 28. The limiting block 30 passes through the protrusion 26 and is locked in the U-shaped tray 9.

[0027] During use, as the sliders on the inner walls of both sides of the U-shaped tray 9 slide from the second slide groove 8 to the first slide groove 4, the U-shaped tray 9 contacts the inclined surface of the limiting block 30. As the U-shaped tray 9 moves, the limiting block 30 moves downward, causing the limiting plate 28 to compress the second spring 29. After the U-shaped tray 9 is engaged with the baffle 5, the second spring 29 resets and pushes the limiting block 30 to engage with the U-shaped tray 9, thus fixing the U-shaped tray 9 on the lifting plate 3. When disassembling the guide rail 6 from the lifting plate 3, the auxiliary handle fixedly installed on the side wall of the winding reel 24 rotates the winding reel 24, causing the winding reel 24 to wind up the traction rope 25, thereby controlling the locking block 19 to move upward until the locking block 19 separates from the baffle 13, which unlocks the guide rail 6 and disassembles it from the lifting plate 3. The operation is convenient and not limited by the cabinet space, and no tools are required, improving the efficiency of disassembling the guide rail and the lifting plate, thereby improving the installation efficiency of the voltage transformer.
