A top frame and a base frame are slidably fitted onto the top and bottom surfaces of the support column, respectively. A groove is provided on one side of the support column. Both the top frame and the base frame are provided with inner plates that slidably engage with the groove. This invention selects a suitable bottom groove based on the actual size of the test clamp, placing the bottom surface of the test clamp's tail end inside the bottom groove.

Description

Technical Field

[0001] This invention belongs to the field of power maintenance robotic arms, and specifically relates to a robotic arm device for power equipment maintenance. Background Technology

[0002] In the daily operation of power equipment, one of the important daily tasks of maintenance personnel is to inspect and test various power components such as transformers involved in the power equipment. This work involves a frequent step: installing test clips into the designated positions of the power equipment and removing the test clips after the test is completed.

[0003] Application CN202110605796.3 discloses a robotic arm device for power equipment maintenance. Through a transmission assembly, the stable rotation of the forward and reverse threaded rods can be controlled, facilitating the synchronous approach and movement of the upper and lower clamping plates. This allows the pneumatically adjustable clamping plate assemblies within the upper and lower clamping plates to reliably clamp and fix the test clamp, and also facilitates the stable delivery of the test clamp to a high position to clamp the power equipment. However, this method only utilizes the upper and lower clamping plates to move and install the test clamp, which mates with a single clamping cavity. When the test clamp does not match the clamping cavity, it cannot maintain stability between the upper and lower clamping plates.

[0004] Therefore, it is necessary to invent a robotic arm device for the maintenance of power equipment to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a robotic arm device for the maintenance of power equipment, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a robotic arm device for power equipment maintenance, comprising a support column, a top frame and a base frame slidably sleeved on the top and bottom surfaces of the support column, respectively, and a groove provided on one side of the support column. Both the top frame and the base frame are provided with inner plates that slidably engage with the groove, and both the top frame and the base frame utilize the inner plates to slidably engage with the groove of the support column. A screw is vertically arranged inside the groove, the top end of the screw penetrating the top surface of the support column, and the top end of the screw spirally penetrating the inner plates of the base frame and the top frame in sequence. A spring is sleeved on the surface of the screw, the spring being located between the top frame and the base frame. A screw hole is provided on the surface of the inner plate that spirally engages with the screw, and the screw hole of the top frame and the screw hole of the base frame have opposite spiral directions. The bottom end of the screw is rotatably connected to the bottom end of the groove, and a drive wheel is fixedly connected to the top end of the screw. The top surface of the drive wheel is connected to the output end of a motor.

[0007] Furthermore, the front and rear sides of the support column are provided with vertical rods, and the top and bottom ends of the vertical rods are fixedly connected to the support column by limiting plates. The vertical rods pass through the top frame and the bottom frame, and the top frame and the bottom frame are slidably engaged with the support column by the vertical rods. The top frame and the bottom frame are provided with through grooves that are slidably engaged with the vertical rods.

[0008] Furthermore, the top frame bottom surface is provided with multiple top grooves, and the bottom frame top surface is provided with multiple bottom grooves, with each top groove corresponding to a bottom groove. The bottom surface of the bottom groove is inclined, and a pressure block is provided inside the top groove. The top frame top surface is provided with a limiting structure for connecting the pressure block. The pressure block is made of rubber material, and the bottom surface of the pressure block is inclined, with the inclination directions of the bottom surface of the pressure block and the bottom surface of the bottom groove being opposite.

[0009] Furthermore, the defined structure includes a frame, which is fixedly installed on the top surface of the top frame. A movable plate is provided inside the frame, and multiple connecting rods are provided on the bottom surface of the movable plate. The connecting rods pass through the top frame, and the top surfaces of multiple pressure blocks are fixedly connected to the movable plate by the multiple connecting rods. The two ends of the movable plate pass through the front and rear ends of the frame, respectively. The front and rear end surfaces of the frame are provided with sliding grooves that slide with the movable plate.

[0010] Furthermore, a rotating frame is rotatably connected to the center of the top surface of the frame, the center of the movable plate is spirally sleeved on the surface of the rotating frame, and the bottom surface of the movable plate is connected to the bottom end of the rotating frame through a torsion spring, and the torsion spring is sleeved on the surface of the rotating frame. A one-way bearing is rotatably sleeved on the top of the rotating frame, and teeth are provided on the outer circumference of the one-way bearing. The drive wheel and the one-way bearing are rotatably connected by a rack and pinion.

[0011] Furthermore, a push plate is provided between the top frame and the bottom frame. The push plate is connected to the top frame and the bottom frame respectively by a connecting structure. A top rod and a bottom rod are provided inside both ends of the push plate. The top rod is located at the top of the bottom rod, and the inner ends of the top rod and the bottom rod are connected by an elastic sheet. A pressure rod is connected to the top of the inner end of the top rod and the bottom of the inner end of the bottom rod. The two pressure rods pass through the top surface and the bottom surface of the push plate respectively, and the two pressure rods are respectively set to correspond to the top frame and the bottom frame.

[0012] Furthermore, the top rod and bottom rod correspond to the top frame and the bottom frame respectively. The top rod and the top frame, as well as the bottom rod and the bottom frame, are connected by rotating plates. One end of each rotating plate is rotatably sleeved on the surface of the top rod and the bottom rod, respectively. The surfaces of the top rod and the bottom rod are spirally sleeved with rotating sleeves.

[0013] Furthermore, the bottom surface of the top frame and the bottom surface of the base frame are arranged horizontally and parallel to each other, and the outer side of the push plate is vertically arranged between the top frame and the base frame.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. According to the actual size of the test clamp, the present invention selects a suitable bottom groove and places the bottom surface of the tail of the test clamp inside the bottom groove. The bottom groove facilitates the test clamp to be in a vertical state. As the top frame and the bottom frame gradually approach each other, the top groove of the top frame gradually snaps into the top surface of the tail of the test clamp. With the relative clamping of the top groove and the bottom groove, and after the top frame and the bottom frame clamp the test clamp with the cooperation of the top groove and the bottom groove, since the bottom surface of the pressure block and the bottom surface of the bottom groove are both inclined, the clamping of the top frame and the bottom frame makes the test clamp gradually approach the support, improving the stability of the test clamp between the top frame and the bottom frame.

[0016] 2. In this invention, when the top frame and the bottom frame approach each other, the top and bottom rotating plates drive the top and bottom rotating plates to rotate simultaneously. The included angle between two adjacent rotating plates gradually decreases during their rotation. The rotation of the two rotating plates causes the push plate to gradually move away from the support column. The outer side of the push plate gradually contacts the tail of the test clamp during the movement, which facilitates the improvement of the clamping stability of the top and bottom frames on the test clamp. When the top and bottom frames approach each other and squeeze the top and bottom pressure rods respectively, the top pressure rod drives the top rod to move down, and the bottom pressure rod drives the bottom rod to move up. When the top and bottom rods squeeze the elastic sheet, the top and bottom rods drive the ends of the two adjacent rotating plates to move. At this time, the two adjacent rotating plates do not rotate during the movement of the top and bottom rods, avoiding excessive movement of the push plate that could cause clamping damage to the test clamp by the top and bottom frames.

[0017] 3. After the test clamp is moved to a suitable position by the robotic arm, the drive wheel rotates counterclockwise, and the one-way bearing drives the near-rotating frame to rotate synchronously. At this time, the rotating frame cooperates with the movable plate to facilitate the downward movement of the pressure block inside the top groove, which helps to reduce the rate of clamping jaw shrinkage of the test clamp. The top groove and bottom groove can ensure the vertical placement of the test clamp, ensuring that the clamping jaw can stably hold the power equipment, avoiding the clamping jaw from shifting during the clamping process, and also avoiding the test clamp from shrinking too quickly, which would cause the test clamp to fail to accurately hold the power equipment. Then the robotic arm is separated from the test clamp, completing the smooth movement and clamping of the test clamp. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides a robotic arm device for the maintenance of power equipment, such as... Figure 1-3As shown, the system includes a support column 1. A top frame 2 and a base frame 3 are slidably fitted onto the top and bottom surfaces of the support column 1, respectively. A groove 4 is provided on one side of the support column 1. Both the top frame 2 and the base frame 3 are provided with inner plates that slidably engage with the groove 4. The top frame 2 and the base frame 3 utilize the inner plates to slidably engage with the groove 4 of the support column 1. A screw 5 is vertically installed inside the groove 4. The top end of the screw 5 penetrates the top surface of the support column 1 and spirally penetrates the inner plates of the base frame 3 and the top frame 2 in sequence. A spring 6 is fitted onto the surface of the screw 5 and is located between the top frame 2 and the base frame 3. A screw hole is provided on the surface of the inner plate that spirally engages with the screw 5. The screw hole of the top frame 2 and the screw hole of the base frame 3 have opposite spiral directions. The bottom end of the screw 5 is rotatably connected to the bottom end of the groove 4, and a drive wheel 7 is fixedly connected to the top end of the screw 5. The top surface of the drive wheel 7 is connected to the output end of the motor. When the existing test clamp needs to be clamped, the motor is started, and the motor drives the drive wheel 7 to rotate. Due to the constraint of the support column 1 on the screw 5, the drive wheel 7 drives the screw 5 to rotate inside the groove 4. The screw holes of the two inner plates are respectively engaged with the screw 5. The rotation of the screw 5 causes the top frame 2 and the bottom frame 3 to move closer or further apart. During the process of the top frame 2 and the bottom frame 3 moving closer together, the spring 6 is clamped, and the test clamp is clamped, thereby improving the stability of the test clamp between the top frame 2 and the bottom frame 3.

[0028] exist Figure 1-Figure 5 In this structure, vertical rods 8 are provided on both the front and rear sides of the support column 1. The top and bottom ends of the vertical rods 8 are fixedly connected to the support column 1 using limiting plates. The vertical rods 8 pass through the top frame 2 and the bottom frame 3, and both the top frame 2 and the bottom frame 3 slide vertically with the support column 1 using the vertical rods 8. Both the top frame 2 and the bottom frame 3 are provided with through grooves 9 that slide with the vertical rods 8. When the top frame 2 and the bottom frame 3 move closer or further apart under the rotation of the screw 5, both the top frame 2 and the bottom frame 3 slide up and down on the surface of the support column 1 using the vertical rods 8. When the top frame 2 and the bottom frame 3 slide up and down on the surface of the support column 1, the two vertical rods 8 can stabilize the top frame 2 and the bottom frame 3 in the front-back direction, preventing the top frame 2 and the bottom frame 3 from shifting during the up and down sliding process, and ensuring the stability of the top frame 2 and the bottom frame 3 during the up and down movement.

[0029] exist Figure 2 , Figure 4 and Figure 5In the above, the bottom surface of the top frame 2 is provided with a plurality of top grooves 10, and the top surface of the bottom frame 3 is provided with a plurality of bottom grooves 11, and the plurality of top grooves 10 and the plurality of bottom grooves 11 are provided in a one-to-one correspondence. The bottom surface of the bottom groove 11 is inclined. A pressure block 12 is provided inside the top groove 10. The top surface of the top frame 2 is provided with a limiting structure for connecting the pressure block 12. The pressure block 12 is made of rubber material, and the bottom surface of the pressure block 12 is inclined. The inclination direction of the bottom surface of the pressure block 12 and the bottom surface of the bottom groove 11 are opposite. Before clamping the test clamp, select a suitable bottom groove 11 according to the actual size of the test clamp, and place the bottom of the tail of the test clamp inside the bottom groove 11. The bottom groove 11 makes it easy for the test clamp to be in a vertical state. As the top frame 2 and the bottom frame 3 gradually approach each other, the top groove 10 of the top frame 2 gradually snaps into the top surface of the tail of the test clamp. With the relative clamping of the top groove 10 and the bottom groove 11, and the top frame 2 and the bottom frame 3 clamping the test clamp with the cooperation of the top groove 10 and the bottom groove 11, since the bottom surface of the pressure block 12 and the bottom surface of the bottom groove 11 are both inclined, the clamping of the top frame 2 and the bottom frame 3 makes the test clamp gradually approach the support column 1, improving the stability of the test clamp between the top frame 2 and the bottom frame 3.

[0030] exist Figure 1 , Figures 3-5 In this structure, the limiting structure includes a frame 13, which is fixedly installed on the top surface of the top frame 2. A movable plate 14 is provided inside the frame 13, and multiple connecting rods 15 are provided on the bottom surface of the movable plate 14. The connecting rods 15 penetrate the top frame 2, and the top surfaces of multiple pressure blocks 12 are fixedly connected to the movable plate 14 by the multiple connecting rods 15. The two ends of the movable plate 14 penetrate the front and rear ends of the frame 13, respectively. Both the front and rear ends of the frame 13 are provided with sliding grooves 16 that slide with the movable plate 14. When the movable plate 14 is limited to the inside of the frame 13, when the top frame 2 moves up and down on the surface of the support column 1, the top frame 2 uses the frame 13 to drive the movable plate 14 to move synchronously. At this time, the movable plate 14 uses the connecting rods 15 to limit the pressure blocks 12 to be inside the top groove 10. When the two ends of the movable plate 14 move up and down inside the sliding groove 16, the movable plate 14 uses the connecting rods 15 to drive the pressure blocks 12 to move up and down inside the top groove 10, thereby changing the relative distance between the bottom surface of the pressure block 12 and the bottom surface of the top frame 2.

[0031] exist Figure 1-Figure 5In this structure, a rotating frame 17 is rotatably connected to the center of the top surface of the frame 13. A movable plate 14 is spirally sleeved onto the surface of the rotating frame 17 at its center. The bottom surface of the movable plate 14 is connected to the bottom end of the rotating frame 17 via a torsion spring 18, which is also sleeved onto the surface of the rotating frame 17. A one-way bearing 19 is rotatably sleeved at the top of the rotating frame 17. The outer circumference of the one-way bearing 19 is provided with teeth. The drive wheel 7 and the one-way bearing 19 are rotatably connected by a rack 20. The rack 20 is horizontally positioned at the top of the support column 1. The height of the one-way bearing 19 is sufficient. When the top frame 2 uses the rotating frame 17 to drive the one-way bearing 19 up and down, the one-way bearing 19 can slide up and down inside the rack 20 using the teeth on its circumferential side. When the drive wheel 7 drives the one-way bearing 19 to rotate via the rack 20, and the drive wheel 7 rotates counterclockwise, the drive wheel 7, via the screw 5, causes the top frame 2 and the bottom frame 3 to move away from each other. Simultaneously, when the rack 20 drives the one-way bearing 19 to rotate, the one-way bearing 19 drives the rotating frame 17 to rotate synchronously. Since the movable plate 14 is helically fitted onto the surface of the rotating frame 17, when the rotating frame 17 rotates and twists the torsion spring 18, the rotation of the rotating frame 17 also causes the movable plate 14 to move downwards inside the frame 13. At this time, the movable plate 14 uses the connecting rod 15 to drive the pressure block 12 to move down inside the top groove 10; when the drive wheel 7 rotates clockwise, the drive wheel 7 uses the screw 5 to rotate so that the top frame 2 and the bottom frame 3 move closer to each other, and when the rack 20 drives the one-way bearing 19 to rotate, the one-way bearing 19 cannot drive the rotating frame 17 to rotate synchronously, and the torque force of the torsion spring 18 makes the rotating frame 17 rotate clockwise, and the rotation of the rotating frame 17 makes the movable plate 14 drive the pressure block 12 to move up inside the top groove 10.

[0032] exist Figure 1 , Figures 4-6 In the process, a push plate 21 is provided between the top frame 2 and the bottom frame 3. The push plate 21 is connected to the top frame 2 and the bottom frame 3 respectively by a connecting structure. A top rod 22 and a bottom rod 23 are provided inside both ends of the push plate 21. The top rod 22 is located at the top of the bottom rod 23, and the inner ends of the top rod 22 and the bottom rod 23 are connected by an elastic sheet 24. A pressure rod 25 is connected to the top of the inner end of the top rod 22 and the bottom of the inner end of the bottom rod 23. The two pressure rods 25 pass through the top surface and the bottom surface of the push plate 21 respectively, and the two pressure rods 25 are respectively set to correspond to the top frame 2 and the bottom frame 3. When the top frame 2 and the bottom frame 3 approach each other, the connecting structure causes the outer side of the push plate 21 to gradually contact the tail of the test clamp. The outer side of the push plate 21 contacts the tail of the test clamp, and the top frame 2 and the bottom frame 3 clamp the test clamp using the top groove 10 and the bottom groove 11. Then, the push plate 21 pushes the tail end face of the test clamp. With the cooperation of the inclined bottom surface of the pressure block 12 and the bottom surface of the bottom groove 11, the stability of the test clamp between the top frame 2 and the bottom frame 3 is further improved, so that the clamping jaw of the test clamp is always vertically to the right during the clamping process.

[0033] exist Figure 1 , Figures 4-6 In this configuration, the top rod 22 and bottom rod 23 correspond to the top frame 2 and the base frame 3, respectively. The top rod 22 is connected to the top frame 2, and the bottom rod 23 is connected to the base frame 3, both using rotating plates 26. One end of each rotating plate 26 is rotatably sleeved onto the surface of the top rod 22 and the bottom rod 23, respectively. Rotating sleeves 27 are spirally sleeved onto the surfaces of both the top rod 22 and the bottom rod 23. The bottom surfaces of the top frame 2 and the base frame 3 are horizontally parallel, and the outer side of the push plate 21 is vertically positioned between the top frame 2 and the base frame 3. When the top frame 2 and the base frame 3 approach each other, they simultaneously rotate the top and bottom rotating plates 26, respectively. The angle between adjacent rotating plates 26 gradually decreases during rotation, and the rotation of the two rotating plates 26 causes the push plate 21 to gradually move away from the support column 1. The outer side of the push plate 21 gradually contacts the tail of the test clamp during movement, thus improving the clamping stability of the test clamp by the top frame 2 and the base frame 3. As the top frame 2 and the bottom frame 3 approach each other, they press the top and bottom pressure rods 25 respectively. The top pressure rod 25 drives the top rod 22 to move downward, and the bottom pressure rod 25 drives the bottom rod 23 to move upward. When the top rod 22 and the bottom rod 23 press the elastic sheet 24, the top rod 22 and the bottom rod 23 drive the ends of the two adjacent rotating plates 26 to move. At this time, the two adjacent rotating plates 26 do not rotate during the movement of the top rod 22 and the bottom rod 23, so as to avoid excessive movement of the push plate 21, which would cause clamping damage to the test clamp by the top frame 2 and the bottom frame 3.

[0034] Working principle of the invention:

[0035] Refer to the attached diagram in the instruction manual. Figures 1-6 When it is necessary to clamp the existing test clamp, the motor is started. The motor drives the drive wheel 7 to rotate. Due to the constraint of the support column 1 on the screw 5, the drive wheel 7 drives the screw 5 to rotate inside the groove 4. The screw holes of the two inner plates are respectively engaged with the screw 5. The rotation of the screw 5 causes the top frame 2 and the bottom frame 3 to move closer or further apart. During the process of the top frame 2 and the bottom frame 3 moving closer together, the spring 6 is clamped. During the process of the top frame 2 and the bottom frame 3 moving closer together, the test clamp is clamped, thereby improving the stability of the test clamp between the top frame 2 and the bottom frame 3.

[0036] When the top frame 2 and the bottom frame 3 approach each other, the top frame 2 and the bottom frame 3 drive the top rotating plate 26 and the bottom rotating plate 26 to rotate simultaneously. The included angle between two adjacent rotating plates 26 gradually decreases during their rotation. The rotation of the two rotating plates 26 causes the push plate 21 to gradually move away from the support column 1. The outer side of the push plate 21 gradually contacts the tail of the test clamp during the movement. The outer side of the push plate 21 contacts the tail of the test clamp. After the top frame 2 and the bottom frame 3 clamp the test clamp using the top groove 10 and the bottom groove 11, the push plate 21 pushes the tail end face of the test clamp. With the cooperation of the inclined bottom surface of the pressure block 12 and the bottom surface of the bottom groove 11, the stability of the test clamp between the top frame 2 and the bottom frame 3 is further improved, so that the clamping jaw of the test clamp is always vertically to the right during the clamping process.

[0037] As the top frame 2 and the bottom frame 3 approach each other, they press the top and bottom pressure rods 25 respectively. The top pressure rod 25 drives the top rod 22 to move down, and the bottom pressure rod 25 drives the bottom rod 23 to move up. When the top rod 22 and the bottom rod 23 press the elastic sheet 24, the top rod 22 and the bottom rod 23 drive the ends of the two adjacent rotating plates 26 to move. At this time, the two adjacent rotating plates 26 do not rotate during the movement of the top rod 22 and the bottom rod 23, so as to avoid excessive movement of the push plate 21, which would cause clamping damage to the test clamp caused by the top frame 2 and the bottom frame 3.

[0038] The entire support column 1 is externally connected to a lifting mechanism. The lifting structure drives the robotic arm to move. After the robotic arm moves the test clamp to a suitable position, the drive wheel 7 rotates counterclockwise. The one-way bearing 19 drives the near-rotating frame 17 to rotate synchronously. At this time, the rotating frame 17 cooperates with the movable plate 14 to facilitate the downward movement of the pressure block 12 inside the top groove 10, which helps to reduce the rate of shrinkage of the test clamp's jaws. The top groove 10 and the bottom groove 11 can ensure the vertical placement of the test clamp, ensuring that the jaws of the test clamp can stably hold the power equipment, preventing the jaws of the test clamp from shifting during the clamping process, and also preventing the test clamp from shrinking too quickly, which would cause the test clamp to fail to accurately hold the power equipment. Then, the robotic arm is separated from the test clamp, completing the smooth movement and clamping of the test clamp.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
