[0019] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of this invention, not all of the embodiments. Based on the embodiments in this invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of this protection.

[0020] See also Figure 1-Figure 15 , this paper provides a technical solution for an electric power maintenance platform.

[0022] When it is needed, the operator stands on the operating plate 3, and then the lifting device 2 drives the operating plate 3 to move to a suitable height. At this time, the shielding plate 8 can play a shielding role. When the vertical plate 7 affects the maintenance operation, the vertical plate 7 can be rotated to the other side by rotating the rotating ring 5, so as not to affect the operation.

[0023] like Figure 2 , Figure 7 and Figure 8 As shown, in order to achieve the adjustment of the height of the baffle plate 8, two lifting seats 9 are fixed on the side of the vertical plate 7 close to the rotating ring 5, and a lifting screw 10 is rotatably connected between the two lifting seats 9. Two fixed blocks 11 are fixed on the side of the vertical plate 7 facing away from the rotating ring 5. The two fixed blocks 11 are both provided with lifting grooves 12, and lifting rods 13 are inserted in the lifting grooves 12. A lifting cross bar 14 is fixed between the lower ends of the two lifting rods 13. A lifting through groove 15 is provided on the vertical plate 7, and a lifting screw block 16 passing through the lifting through groove 15 is fixed on the lifting cross bar 14. The lifting screw 10 is threadedly connected to the lifting screw block 16, and the baffle plate 8 is arranged between the two lifting rods 13.

[0024] When the height of the shielding plate 8 needs to be adjusted, the lifting screw block 16 can be moved up and down by rotating the lifting screw rod 10. The up and down movement of the lifting screw block 16 can drive the lifting cross bar 14 to move, thereby driving the two lifting rods 13 to move relative to the lifting slide slot 12, so that the shielding plate 8 is adjusted to a suitable height.

[0025] like Figure 4-Figure 8 A limiting groove 17 is provided on the rotating ring 5 and the horizontal connecting plate 6, a limiting through groove 18 is provided on the upper side of the limiting groove 17, a limiting rod 19 is inserted in the limiting groove 17, and a plurality of limiting grooves 20 are provided on the bottom surface of the rotating ring groove 4, and the plurality of limiting grooves 20 are evenly distributed around the axis of the rotating ring 5. A limiting protrusion 21 passing through the limiting through groove 18 is fixed on the limiting rod 19.

[0026] When the rotating ring 5 rotates to a suitable position, the end of the limiting rod 19 is plugged into the corresponding limiting groove 20, so that the positions of the rotating ring 5 and the operating plate 3 are limited to prevent the rotating ring 5 from rotating randomly.

[0027] like Figure 4-Figure 8 In order to facilitate the restriction of the position of the rotating ring 5, a rotating groove 22 is provided at the lower end of the lifting screw 10, a lower through hole 23 is provided at the lower side of the rotating groove 22, and an upper through hole 24 is provided at the upper side of the rotating groove 22. A rotating column 25 is installed in the rotating groove 22, and the rotating column 25 can rotate relative to the rotating groove 22. A lower extension column 26 is provided at the lower end of the rotating column 25, and a lower push rod 27 is hingedly connected to one end of the lower extension column 26 extending out of the lower through hole 23. The lower push rod 27 is hinged to the limiting protrusion 21, and a telescopic spring 28 is sleeved on the lower extension column 26. The telescopic spring 28 is arranged between the lower side of the rotating groove 37 and the rotating column 25. A pressing rod 29 is inserted into the upper through hole 24, and the lower end of the pressing rod 29 abuts against the upper side of the rotating column 25.

[0028] like Figure 4-Figure 8When the lifting screw 10 rotates normally, the position of the rotating column 25 does not move. When the position of the rotating ring 5 needs to be adjusted, the rotating column 25 can be driven to move downward by pressing the upper end of the pressing rod 29. The rotating column 25 drives the end of the limiting rod 19 to move out of the limiting groove 20 through the lower extension column 26 and the lower push rod 27. At this time, the rotating ring 5 is in an unlocked state and the rotating ring 5 can rotate normally. After rotating to a suitable position, the pressing rod 29 is released, and the telescopic spring 28 drives the rotating column 25 to move upward, thereby driving the limiting rod 19 to plug into the limiting groove 20 at the corresponding position. The locking and unlocking of the rotating ring 5 is very convenient, and only needs to be operated at the upper end of the lifting screw 10.

[0029] like Figure 9-14 As shown, in order to adjust the angle of the shielding plate 8, a rotating hole 30 is provided at the upper end of the lifting rod 13, a rotating shaft 31 is fixed on the shielding plate 8, and the two ends of the rotating shaft 31 are rotatably connected to the two rotating holes 30 respectively, and a positioning slide 32 connected to the rotating hole 30 is provided on the lifting rod 13, and a positioning telescopic groove 33 is provided on the lower side of the positioning slide 32, and a positioning telescopic rod 34 is inserted in the positioning telescopic groove 33, and a fixing ring body 35 is fixed on the positioning telescopic rod 34, and a positioning spring 36 is sleeved on the positioning telescopic rod 34. The positioning spring 36 is arranged between the bottom surface of the positioning slide groove 32 and the fixed ring body 35. A plurality of rotating grooves 37 are provided on the outer wall of the rotating shaft 31. The plurality of rotating grooves 37 are evenly distributed around the axis of the rotating shaft 31. The upper end of the positioning telescopic rod 34 is plugged into the corresponding rotating groove 37. A positioning side groove 39 is provided on the side of the lifting rod 13 close to the rotating ring 5. The positioning side groove 39 is connected to the positioning telescopic groove 33. A positioning driven protrusion 38 is fixed on the positioning telescopic rod 34, and the positioning driven protrusion 38 is located in the positioning side groove 39.

[0030] like Figure 9-14 As shown, when the angle of the baffle plate 8 needs to be adjusted, it is only necessary to pull down the positioning driven protrusion 38, thereby driving the upper end of the positioning telescopic rod 34 to move out of the rotating groove 37. At this time, the angle of the baffle plate 8 can be adjusted. After the adjustment is completed, release the driven protrusion 38, and the positioning spring 36 drives the positioning telescopic rod 34 to move upward, so that the upper end of the positioning telescopic rod 34 is plugged into the corresponding rotating groove 37, thereby positioning the position of the baffle plate 8.

[0031] like Figure 7-Figure 14As shown, in order to facilitate the adjustment of the angle of the shielding plate 8, the positioning side groove 39 includes a positioning inner groove 40 and a positioning outer groove 41. A positioning push rod 42 is installed in the positioning inner groove 40. The positioning push rod 42 is located in the positioning inner groove 40 and can move in the positioning inner groove 40. An active protrusion 43 corresponding to the driven protrusion 38 is fixed on the positioning push rod 42. An active inclined surface 44 is provided on the active protrusion 43. A driven inclined surface 45 is provided on the driven protrusion 38. The active inclined surface 44 and the driven inclined surface 45 are in contact. A pushing groove 46 connected to the corresponding lifting slide groove 12 is provided on the vertical plate 7. A pushing cross bar 47 is inserted in the pushing groove 46. A pushing linkage rod 48 is fixed between the ends of the two pushing cross bars 47 away from the positioning push rod 42. A pushing fixing plate 49 is fixed on the pushing linkage rod 48 , a pushing bolt 50 is passed through the pushing fixing plate 49 , a pushing threaded hole 51 is provided on the lifting seat 9 on the upper side, and the pushing bolt 50 is threadedly connected with the pushing threaded hole 51 .

[0032] When the angle of the shielding plate 8 needs to be adjusted, the push bolt 50 is screwed into the lifting seat 9 on the upper side, driving the push linkage rod 48 to move toward the lifting seat 9, thereby driving the push cross bar 47 to push the corresponding positioning push rod 42 inward, and the active inclined surface 44 on the active protrusion 43 on the positioning push rod 42 drives the positioning telescopic rod 34 to move downward by squeezing the driven inclined surface 45 on the driven protrusion 38, so that the upper end of the positioning telescopic rod 34 moves downward out of the rotating groove 37, and the angle of the shielding plate 8 can be easily adjusted. After the angle adjustment is completed, the push cross bar 47 is screwed in the opposite direction. At this time, the positioning spring 36 drives the positioning telescopic rod 34 to move upward, so that the upper end of the positioning telescopic rod 34 is plugged into the corresponding rotating groove 37, thereby positioning the position of the shielding plate 8. In other words, you only need to rotate the push cross bar 47 to limit and unlock the position of the shielding plate 8. When shielding is not needed, you can Figure 1 In the state of falling, the shielding plate 8 rotates 270° counterclockwise and is folded.
