[0058] The embodiment of the present invention discloses a 10kV trolley switch intelligent operation and maintenance device and a method for using the same. Figure 1-8The present invention is described in further detail.
[0059] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.
[0062] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific conditions.
[0063] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
[0064] The embodiment of the present invention discloses a 10kV trolley switch intelligent operation and maintenance device and a use method thereof.
[0065] Referring to the figure, a 10kV trolley switch intelligent operation and maintenance device includes a lifting trolley body 1 and a hanger 2 fixed on one side of the lifting trolley body 1.
[0066] Reference Figure 1 and Figure 2The lifting trolley body 1 includes a shell 143, in which a permanent magnet DC motor 142 and a battery 141 are installed. The battery 141 is electrically connected to the permanent magnet DC motor 142, so that the battery 141 supplies power to the permanent magnet DC motor 142.
[0067] At the same time, forearms 13 are fixed on both sides of the shell 143. The two forearms 13 are parallel to each other and one end extends out of the shell 143. A rear caster 16 is installed on the side of the shell 143 away from the hanger 2, and a foot brake is installed on the rear caster 16. Front casters 17 are installed on the side of the two forearms 13 away from the rear casters 16. The rear casters 16 and the front casters 17 jointly support the lifting trolley body 1.
[0068] In addition, a first side plate 11 is fixed on both forearms 13. In the present embodiment, a handle 15 is fixed on the side of both first side plates 11 away from the hanger 2, so that the technician can push the entire device to slide through the handle 15. After reaching the destination, the foot brake on the rear caster 16 can keep the entire device stationary on the ground.
[0069] A lifting rail 111 is fixed on opposite sides of the two first side panels 11 , and a tray 12 is installed between the two lifting rails 111 . The tray 12 is matched with the inner walls of the trolley switch cabinet on both sides, and one end of the tray 12 extends out of the hanger 2 .
[0070] In this embodiment, positioning holes (not shown in the figure) adapted to the tongue of the trolley switch 6 are provided on both sides of the tray 12, so as to facilitate the positioning of the trolley switch 6. The tongue is the structure of the trolley switch 6 in the prior art, and its function is to fix the trolley switch 6 in the trolley switch cabinet.
[0071] The permanent magnet DC motor 142 can pull the tray 12 up and down along the lifting guide rail 111. At the same time, since the tray 12 is compatible with the inner walls on both sides of the trolley switch cabinet, the tray 12 can extend one end of the hanger 2 and be inserted into the trolley switch cabinet, and all the trolley switches 6 in the trolley switch cabinet can be transported out at one time through the tray 12, thereby improving the maintenance efficiency of the trolley switch 6.
[0072] In addition, the lower part of the lifting guide rail 111 is inclined toward the side away from the hanger 2, so that when the pallet 12 is lowered to close to the ground, the pallet 12 is inclined relative to the ground, and the pallet 12 extends out of one side of the hanger 2 and abuts against the ground, thereby facilitating the loading and unloading of the trolley switch 6 located on the ground by the pallet 12.
[0073] Reference Figure 1 and Figure 3The hanger 2 includes a second side plate 21 and a transverse plate 22, wherein the number of the second side plates 21 and the transverse plate 22 are both two, and the two second side plates 21 are respectively fixed on the side of the two forearms 13 away from the shell 143, and the two transverse plates 22 are parallelly and spaced apart between the two second side plates 21.
[0074] In addition, two pulley blocks 37 are slidably connected to the two horizontal plates 22, and the pulley blocks 37 slide along the length direction of the horizontal plates 22. The bottoms of the two pulley blocks 37 are fixed with hanging plates 3, and connecting frames 53 are fixed to the opposite sides of the two hanging plates 3. The connecting frames 53 are threadedly connected with lead screws 52, and the axial direction of the lead screws 52 is in the same direction as the length direction of the horizontal plates 22. The opposite sides of the two second side plates 21 are rotatably connected with adjustment handles 51, and the lead screws 52 penetrate the second side plates 21 and are connected to the adjustment handles 51.
[0075] When the adjusting handle 51 is driven to rotate, the adjusting handle 51 drives the lead screw 52 to rotate, and since the connecting frame 53 is threadedly connected to the lead screw 52, the connecting frame 53 drives the hanging plate 3 and the pulley block 37 to slide along the length direction of the horizontal plate 22. When the adjusting handles 51 on both sides are rotated at the same time, the two hanging plates 3 can slide toward or away from each other.
[0076] In addition, in order to prevent the two hanging plates 3 from colliding with each other due to the small distance between them during the sliding process, a limit block 31 and a fixed block 33 are sandwiched between the two horizontal plates 22. The limit block 31 is slidably connected to the two horizontal plates 22, and the sliding direction is along the length direction of the horizontal plate 22. There are two limit blocks 31 and two fixed blocks 33, and the two limit blocks 31 are located between the two pulley blocks 37, and the two fixed blocks 33 are located between the two limit blocks 31.
[0077] A threaded hole is provided on one side of the two fixing blocks 33 close to the limit block 31 , and an adjusting bolt 32 is threadedly connected to the threaded hole. The adjusting bolt 32 is in the same direction as the length of the cross plate 22 , and one end of the adjusting bolt 32 is rotatably connected to the limit block 31 through a bearing.
[0078] When the adjusting bolt 32 is rotated, the adjusting bolt 32 is threadedly connected with the fixing block 33, thereby driving the limit block 31 to slide along the length direction of the horizontal plate 22. When the pulley block 37 slides to abut against the limit block 31, the limit block 31 limits the sliding of the pulley block 37 on the horizontal plate 22. The position of the limit block 31 can be adjusted by adjusting the bolt 32, thereby adjusting the minimum distance between the two hanging plates 3.
[0079] In addition, in order to keep the two hanging plates 3 fixed after sliding, guide rods 34 are fixed on the opposite surfaces of the two second side plates 21. The guide rods 34 are in the same direction as the length direction of the cross plate 22. A slider 35 is slidably sleeved on the guide rod 34, and a fastening bolt 36 is installed on the slider 35 for fixing the slider 35.
[0080] At the same time, through holes matching the guide rods 34 are provided on the side walls of the two hanging plates 3 , so that the guide rods 34 can pass through the hanging plates 3 through the through holes, and the hanging plates 3 are fixedly connected to the sliders 35 .
[0081] When the fastening bolts 36 are loosened, the hanging plate 3 can drive the slider 35 to slide along the guide rod 34 when sliding. When the fastening bolts 36 are tightened, the slider 35 is fixed, so that the hanging plate 3 is fixed together with the slider 35 .
[0082] In addition, a rotating plate 4 is rotatably connected to the two hanging plates 3 on opposite sides via a rotating shaft, and a latch 41 adapted to the heat dissipation holes on both sides of the trolley switch 6 is fixed on the opposite sides of the two rotating plates 4 .
[0083] Reference Figure 3 and Figure 4 In this embodiment, two latches 41 are distributed on the single rotating plate 4, so as to be compatible with the trolley switch 6 in this embodiment.
[0084] When the handle 51 is adjusted to make the hanging plates 3 on both sides drive the rotating plates 4 to move toward each other, the pins 41 on the rotating plates 4 on both sides can be inserted into the heat dissipation holes on both sides of the trolley switch 6, so that the rotating plates 4 on both sides clamp the trolley switch 6 together.
[0085] In addition, in order to drive the rotating plate 4 to rotate, a flip handle 421 is rotatably connected to the side wall of the second side plate 21 on one side, and a reducer 422 is installed on the side of the flip handle 421 close to the rotating plate 4, the input end of the reducer 422 is connected to the flip handle 421, and the output end of the reducer 422 is coaxially connected to the rotating shaft of the rotating plate 4.
[0086] When the flip handle 421 is driven to rotate, the flip handle 421 can drive the rotating plate 4 to rotate through the reducer 422, thereby driving the trolley switch 6 sandwiched between the two rotating plates 4 to flip, and the rotating plate 4 on the other side rotates following the trolley switch 6. During the flipping process, there is no need for technicians to directly touch the trolley switch 6 to flip it, which improves the safety of the trolley switch 6 when flipping, and the reducer 422 can save effort during the flipping of the trolley switch 6 by the flip handle 421.
[0087] In addition, in order to limit the rotation of the driven side rotating plate 4 , a limiting screw 232 and a spring pin 231 for limiting the position of the rotating plate 4 are installed on the rotating plate 4 on the side away from the flip handle 421 .
[0088] Specifically, refer to Figure 5 and Figure 6The spring pin 231 is fixed on the side of the hanging plate 3 away from the driven side rotating plate 4, the limiting stud 232 is slidably inserted on the spring pin 231, and the end of the limiting stud 232 away from the spring pin 231 passes through the hanging plate 3 and extends out of the rotating plate 4, wherein the spring pin 231 and the limiting stud 232 are both existing technologies, and their structures are not repeated here.
[0089] Reference Figure 7 In this embodiment, the rotating plate 4 is a diamond-shaped plate, and the number of the limiting studs 232 is two, and the two limiting studs 232 are respectively located at two opposite sides of the rotating plate 4 in the unflipped state.
[0090] Reference Figure 8 When the rotating plate 4 is flipped over, the spring pin 231 pushes the limiting stud 232 to pop out through the pull ring on the spring pin 231 (not shown in the figure), and the two limiting studs 232 limit the driven side rotating plate 4 to prevent the driven side rotating plate 4 from rotating, further improving the safety of the trolley switch 6 when flipping.
[0091] When the limiting stud 232 is retracted again by the pull ring on the spring pin 231, the limiting stud 232 no longer limits the driven side rotating plate 4, so that the trolley switch 6 can be freely flipped again.
