Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, and in particular relates to electric power equipment maintenance equipment. Background Art

[0002] Power maintenance is mainly divided into the following maintenance parts: power generation part, power supply part, substation part and distribution part. Each part is responsible for specialized personnel to inspect power equipment, including power generation equipment, substation equipment, power supply lines, etc.

[0003] In the process of maintaining power equipment, some power equipment is usually installed at a high place, so that personnel need to use lifting equipment to rise to the maintenance height for maintenance. The existing power maintenance devices are mostly fixed in size when in use. Since they cannot be adjusted laterally, the working range of the staff is small. In response to the above technical problems, the Chinese patent with patent announcement number CN215452292U, when in use, the second electric push rod arranged inside the device pushes the offset box to move, thereby driving the third electric push rod to move, and the anti-slip plate is driven to move by the third electric push rod, so as to complete the lateral movement of the maintenance personnel. However, during the adjustment process, due to the width of the offset box and the length installation limitation of the second electric push rod, the moving range of the offset box is small, which in turn leads to a limited increase in the working range, reducing the practicality of the equipment. Summary of the invention

[0004] The object of the present invention is to provide an electric power equipment maintenance device, aiming to solve the technical problem in the prior art that the supporting component has a small moving range, resulting in a limited working range that can be increased.

[0005] The present invention is implemented as follows: an electric power equipment maintenance device comprises a base, on which a plurality of telescopic rods are fixedly mounted, a lifting plate is fixedly connected to the tops of the plurality of telescopic rods, and a plurality of telescopic members for driving the lifting plate to move up and down are fixedly mounted on the base;

[0006] A top plate is slidably mounted on the lifting plate, a mounting groove is provided in the middle of the surface of the top plate in contact with the lifting plate, a rack is fixedly mounted in the mounting groove, a through groove connected to the mounting groove is provided in the middle of the lifting plate, connecting shafts are rotatably mounted at both ends of the through groove, a connecting gear meshing with the rack is fixedly mounted on the end of the connecting shaft close to the top plate, a rotating shaft is rotatably mounted on the lifting plate, the rotating shaft is rotatably connected to the two sets of connecting shafts through a bevel gear set, a rotating power part that drives the rotating shaft to rotate is fixedly mounted on the lifting plate, and a counterweight block is provided in the middle of the base.

[0008] Further technical solution: a fence is provided on the top plate, and pillars are fixedly installed on the four sides of the top plate. The end of the pillar away from the top plate is fixedly connected to the fence. Limit plates are slidably installed on the pillars at both ends of the top plate. The vertical section of the limit plate passes through the lifting plate. A rotating rod is rotatably installed on the end of the top plate, and the rotating rod drives the limit plate to move through a thread.

[0009] Further technical solution: A screw rod is rotatably installed on the lifting plate, which is parallel to the rotating shaft and rotatably connected to the rotating shaft through a transmission gear. Two groups of transmission gears are provided, and the connection modes of the transmission gear and the rotating shaft and the screw rod are respectively rotational connection and fixed connection. The screw rod drives the support plate slidably installed on the lifting plate to move, and a winch is fixedly installed on the surface of the support plate close to the base. A steel wire rope is wound around the winch, and the steel wire rope is connected to the counterweight block.

[0010] Further technical solution: A base plate is fixedly installed on the rotating shaft, and multiple groups of connecting rods are slidably installed on the base plate. The connecting rods penetrate the base plate and are parallel to the rotating shaft. An annular friction plate and a magnet ring are fixedly installed at both ends of the connecting rods. The magnet ring is close to the side of the lifting plate, and an electromagnet ring is fixedly installed on the side of the lifting plate. The electromagnet ring is arranged around the rotating shaft and is coaxial with the rotating shaft. When the electromagnet ring is energized, it repels the magnet ring and pushes the friction plate to contact the transmission gear.

[0011] Further technical solution: a guide frame is fixedly installed on the base, a movable plate is slidably installed on the guide frame, a pulley is arranged at the bottom of the movable plate, a counterweight block is located on the movable plate, and a fixing screw is threadedly connected on the movable plate.

[0012] Further technical solution: The lifting plate is provided with placement grooves on both sides of the through groove, and an L-shaped support frame is slidably installed in the placement groove. A magnet block is fixedly installed on the top of the vertical section of the support frame. The upper surface of the magnet block is flush with the lower surface of the top plate, and multiple groups of iron blocks are fixedly installed on the lower surface of the top plate, and the magnet block is located on the moving path of the iron block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The rotating shaft is driven to rotate by a rotating power part. When the rotating shaft rotates, the two sets of connecting shafts are driven to rotate synchronously through the bevel gear set, and the rotation directions of the two sets of connecting shafts are the same. When the connecting shaft rotates, the top plate is driven to move laterally through the meshing connecting gears and racks. Since the two sets of connecting shafts are distributed on both sides of the through groove, when the top plate moves in a certain direction, the connecting shaft on the same side can drive the top plate to move, so that the top plate can move laterally for a large length, so that the staff can obtain a larger working range, increase the working range of the staff, and the overall center of gravity of the device is lowered by the counterweight block, thereby increasing the stability of the equipment, and ensuring that the center of gravity of the equipment is located in the area surrounded by the support points of the base when the top plate is extended out of the lifting plate for use, thereby avoiding the equipment from tipping over due to the shift of the center of gravity of the equipment, thereby improving the safety of equipment use.

[0015] 2. After adjusting the moving distance of the top plate, the winch will reel in the wire rope. The wire rope will first be straightened, and then the moving plate will be pulled on the base through the counterweight. When the moving plate moves to the bottom of the winch, the winch stops reeling in the wire rope. The wire rope is in a vertical state and has no pulling force on the counterweight. At this time, the position of the moving plate is fixed by fixing screws to ensure the stability of the position of the moving plate, realize the synchronous reverse movement of the counterweight and the top plate, ensure that the center of gravity of the device falls within the area surrounded by the support points of the base, ensure the stability of the equipment, and further improve the safety of the equipment.

[0016] 3. When the top plate extends a short length and a large weight needs to be placed on the end of the top plate, after the position of the movable plate is automatically adjusted, the winch releases the wire rope again, and then the staff pushes the movable plate to continue to move to the farthest position and fix it. At this time, it can be ensured that heavier materials can be placed on the top plate, which improves the flexibility of adjusting the counterweight block and further improves the stability and safety of the top plate during lateral movement.

[0017] 4. When the top plate moves horizontally for a long length, the iron block contacts the magnet block driven by the top plate. Since the adsorption force between the magnet block and the side of the lifting plate is smaller than the adsorption force between the magnet block and the iron block, the support frame moves with the top plate under the traction of the iron block. Therefore, when the top plate is extended to a long length, the support frame can support the middle part of the area where the top plate extends out of the lifting plate, avoiding deformation and bending of the top plate, further ensuring the stability of the top plate and improving the safety of equipment use.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1-Figure 8 As shown, an electric power equipment maintenance device provided by the present invention comprises a base 1, on which a plurality of telescopic rods 3 are fixedly mounted, a lifting plate 4 is fixedly connected to the tops of the plurality of telescopic rods 3, and a plurality of telescopic members 2 for driving the lifting plate 4 to move up and down are fixedly mounted on the base 1;

[0030] A top plate 6 is slidably mounted on the lifting plate 4, and a plurality of connecting grooves 5 with inverted T-shaped cross-sections are provided on the lifting plate 4. A connecting plate 7 is slidably mounted in the connecting groove 5, and the connecting plate 7 is fixedly connected to the top plate 6. A mounting groove 20 is provided in the middle of the surface of the top plate 6 in contact with the lifting plate 4, and a rack 19 is fixedly mounted in the mounting groove 20. A through groove 15 connected to the mounting groove 20 is provided in the middle of the lifting plate 4, and connecting shafts 16 are rotatably mounted at both ends of the through groove 15. A connecting gear 18 meshing with the rack 19 is fixedly mounted on the end of the connecting shaft 16 close to the top plate 6. A rotating shaft 12 is rotatably mounted on the lifting plate 4, and the rotating shaft 12 is rotatably connected to the two groups of connecting shafts 16 through a bevel gear set. A rotating power member 13 for driving the rotating shaft 12 to rotate is fixedly mounted on the lifting plate 4, and a counterweight block 27 is provided in the middle of the base 1.

[0031] In actual application of this embodiment, the base 1 is pushed to move to the maintenance position and fixed, the staff stands on the top plate 6 and the tools and equipment used for maintenance can be placed on the top plate 6, and then the telescopic member 2 drives the lifting plate 4 to move upward to the maintenance height, and the movement of the lifting plate 4 is guided and restricted by multiple sets of telescopic rods 3, so as to improve the stability of the lifting plate 4 during the movement;

[0032] When the top plate 6 needs to move laterally to increase the working range, the rotating shaft 12 is driven to rotate by the rotating power part 13. When the rotating shaft 12 rotates, the two sets of connecting shafts 16 are driven to rotate synchronously through the bevel gear set, and the rotation directions of the two sets of connecting shafts 16 are the same. When the connecting shaft 16 rotates, the top plate 6 is driven to move laterally through the meshing connecting gear 18 and the rack 19. The top plate 6 stops moving after moving to the set position. The moving direction of the top plate 6 can be changed by changing the rotation direction of the rotating power part 13, and the two sets of connecting shafts 16 are located on both sides of the through groove 15. When the top plate 6 moves in a certain direction, the connecting shaft 16 on the same side can drive the top plate 6 to move, so that the top plate 6 can move laterally for a larger length, so that the staff can obtain a larger working range, and the overall center of gravity of the device is lowered by the counterweight block 27, thereby increasing the stability of the equipment, and ensuring that the center of gravity of the equipment is located in the area surrounded by the support points of the base 1 when the top plate 6 is extended out of the lifting plate 4 for use, thereby avoiding the equipment from tipping over due to the deviation of the center of gravity of the equipment, thereby improving the safety of the equipment.

[0033] In an example of the present embodiment, the rotating power part 13 is a motor, and of course it can also be other parts that can output rotating power, such as a hydraulic motor. The motor drives the rotating shaft 12 to rotate, thereby controlling the lateral movement of the top plate 6. The telescopic part 2 is an electric telescopic rod, and of course it can also be other parts that can actively change the length, such as a hydraulic cylinder. The electric telescopic rod drives the lifting plate 4 to move up and down. The bevel gear set is provided with two sets of bevel gears 14, and the two sets of bevel gears 14 are respectively fixedly mounted on the rotating shaft 12 and the connecting shaft 16. The rotating shaft 12 and the connecting shaft 16 are rotatably connected through the two meshing sets of bevel gears 14.

[0034] like Figure 1-Figure 6 As shown, a power equipment maintenance device provided by the present invention is provided with a fence 9 on the top plate 6, and pillars 8 are fixedly installed on the four sides of the top plate 6. The end of the pillar 8 away from the top plate 6 is fixedly connected to the fence 9, and limit plates 11 are slidably installed on the pillars 8 at both ends of the top plate 6. The vertical section of the limit plate 11 passes through the lifting plate 4, and a rotating rod 10 is rotatably installed on the end of the top plate 6. The rotating rod 10 drives the limit plate 11 to move through a thread.

[0035] In actual application of this embodiment, the fence 9 is used to block the four sides of the top plate 6 to improve the safety of the staff during operation. The limit plates 11 at both ends are used to limit the top plate 6, thereby preventing the top plate 6 from moving at will, further improving the stability of the top plate 6. When the top plate 6 needs to be moved, the staff rotates the rotating rod 10, and the rotating rod 10 drives the limit plate 11 to move upward through the thread. When the limit plate 11 is no longer in contact with the lifting plate 4, the limit plate 11 can release the restriction on the top plate 6, and the top plate 6 can be moved at will.

[0036] like Figure 2-Figure 8 As shown, an electric power equipment maintenance equipment provided by the present invention, a screw rod 30 is rotatably installed on the lifting plate 4, the screw rod 30 is parallel to the rotating shaft 12 and is rotatably connected to the rotating shaft 12 through a transmission gear 17, and two groups of transmission gears 17 are provided. The connection modes of the transmission gear 17 with the rotating shaft 12 and the screw rod 30 are respectively rotationally connected and fixedly connected. The screw rod 30 drives the support plate 28 slidably installed on the lifting plate 4 to move, and a winch 29 is fixedly installed on the surface of the support plate 28 close to the base 1, and a steel wire rope is wound around the winch 29, and the steel wire rope is connected to the counterweight block 27.

[0037] Specifically, a base plate 32 is fixedly mounted on the rotating shaft 12, and a plurality of connecting rods 35 are slidably mounted on the base plate 32. The connecting rods 35 penetrate the base plate 32 and are parallel to the rotating shaft 12. An annular friction plate 34 and a magnet ring 33 are fixedly mounted at both ends of the connecting rod 35. The magnet ring 33 is close to the side of the lifting plate 4. An electromagnet ring 31 is fixedly mounted on the side of the lifting plate 4. The electromagnet ring 31 is arranged around the rotating shaft 12 and is coaxial with the rotating shaft 12. When the electromagnet ring 31 is energized, it repels the magnet ring 33 and pushes the friction plate 34 to contact the transmission gear 17.

[0038] Specifically, a guide frame 25 is fixedly mounted on the base 1 , a movable plate 26 is slidably mounted on the guide frame 25 , a pulley is provided at the bottom of the movable plate 26 , a counterweight block 27 is located on the movable plate 26 , and a fixing screw is threadedly connected to the movable plate 26 .

[0039] In actual application of this embodiment, when the top plate 6 needs to move laterally, the winch 29 first releases a sufficient length of the wire rope to make the wire rope in a relaxed state, and the electromagnet ring 31 is energized. After the electromagnet ring 31 is energized, the magnet ring 33 is repelled and the friction plate 34 is pushed to contact the transmission gear 17. At this time, when the rotating shaft 12 rotates, the transmission gear 17 thereon can be driven to rotate synchronously, and then the rotating shaft 12 can drive the screw rod 30 to rotate through the meshing transmission gear 17, and the screw rod 30 drives the support plate 28 to move. The moving direction of the support plate 28 is opposite to that of the top plate 6. When the top plate 6 moves laterally out of the lifting plate 4 to the limit position, the support plate 28 also moves to the limit position;

[0040] After adjusting the moving distance of the top plate 6, the winch 29 reels the wire rope, the wire rope will first be straightened, and then the moving plate 26 will be pulled to move on the base 1 through the counterweight 27, and the friction between the moving plate 26 and the base 1 will be reduced by the pulley on the moving plate 26, so that only a small force is needed to pull the moving plate 26 to move, ensuring that the wire rope can pull the moving plate 26. When the moving plate 26 moves to the bottom of the winch 29, the winch 29 stops reeling in the wire rope, the wire rope is in a vertical state and has no pulling force on the counterweight 27. At this time, the position of the moving plate 26 is fixed by fixing screws to ensure the stability of the position of the moving plate 26, and the synchronous reverse movement of the counterweight 27 and the top plate 6 is achieved, ensuring that the center of gravity of the device falls within the area surrounded by the supporting points of the base 1, ensuring the stability of the equipment, and further improving the safety of the equipment.

[0041] When the top plate 6 extends a shorter length and a heavier weight needs to be placed on the end of the top plate 6, after the position of the movable plate 26 is automatically adjusted, the winch 29 releases the wire rope again, and then the staff pushes the movable plate 26 to continue moving to the farthest position and fix it. At this time, it can be ensured that heavier materials can be placed on the top plate 6, which improves the flexibility of adjusting the counterweight block 27 and further improves the stability and safety of the top plate 6 during lateral movement.

[0042] like Figure 1-Figure 4 As shown, an electric power equipment maintenance device provided by the present invention is provided with placement grooves 22 located on both sides of the through groove 15, and an L-shaped support frame 23 is slidably installed in the placement groove 22. A magnet block 24 is fixedly installed on the top of the vertical section of the support frame 23. The upper surface of the magnet block 24 is flush with the lower surface of the top plate 6, and multiple groups of iron blocks 21 are fixedly installed on the lower surface of the top plate 6. The magnet block 24 is located on the moving path of the iron block 21.

[0043] In actual application of this embodiment, when the top plate 6 moves laterally and before the iron block 21 contacts the magnet block 24, the support frame 23 is fixed by the magnet block 24 and the side adsorption of the lifting plate 4. When the top plate 6 moves laterally for a long distance, the iron block 21 contacts the magnet block 24 driven by the top plate 6. Since the adsorption force of the magnet block 24 and the side of the lifting plate 4 is less than the adsorption force of the magnet block 24 and the iron block 21, the support frame 23 moves with the top plate 6 under the traction of the iron block 21. Therefore, when the top plate 6 is extended to a long length, the support frame 23 can be used to support the middle part of the area where the top plate 6 extends out of the lifting plate 4, thereby avoiding deformation and bending of the top plate 6, further ensuring the stability of the top plate 6, and improving the safety of equipment use. When the top plate 6 is subsequently reset, it will push the support frame 23 to reset.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
