Description

Technical Field

[0001] This application relates to the field of lightning protection testing equipment technology, and more specifically, to a robotic arm device for lightning protection testing. Background Technology

[0002] Lightning protection systems are essential for the safety of buildings and electrical equipment. Regular testing of the grounding resistance at each grounding point is necessary to ensure proper grounding. During a lightning strike, the current can flow directly to the ground through the grounding device, thus protecting the electrical equipment and buildings.

[0003] In response, Chinese patent application number CN202020016267.0 discloses a lightning protection detection system based on an intelligent robot. This solution mainly uses walking wheels and steering wheels to enable the robot to move straight and turn on the ground, which facilitates the movement of the intelligent robot indoors. The electric telescopic pole facilitates the driving of the gripper and camera to reach the required detection height. The rotating arm can rotate in the numerical plane under the drive of the drive device, thereby adjusting the gripper to a suitable detection angle.

[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this utility model discovered that the above-mentioned technology has at least the following technical problems:

[0005] Some test points are located deep inside the equipment, but the robotic arm itself is thick and the gripper structure is large, making it impossible to pass through narrow gaps to enter the deep part of the equipment for testing. Utility Model Content

[0006] To overcome the above deficiencies, this application provides a robotic arm device for lightning protection detection, which aims to improve the problems mentioned in the background art.

[0007] This application provides a robotic arm device for lightning protection detection, including a base mounted on the front end of the robotic arm, a probe slidably connected through the base, a driving component on the base to drive the probe to move axially, an elastic clamp inside the head end of the probe, a push-pull component inside the probe to drive the clamp to retract or extend, a wire fixedly connected to the rear end of the clamp to connect to lightning protection detection equipment, and a lead wire mechanism inside the probe to be adapted to the wire.

[0008] In one specific implementation, the driving component includes a worm gear and a worm, both of which are rotatably connected to the base. The worm gear meshes with the worm and is threadedly connected to the probe rod.

[0009] In one specific implementation, the drive unit further includes a motor, which is mounted on the base, and the output end of the motor is fixedly connected to the worm gear.

[0010] In the above implementation process, in this embodiment, the probe has a square cross-section and can only slide axially with the base, but cannot rotate. The motor drives the worm gear, which in turn drives the worm wheel to rotate. The worm wheel and the probe are connected by a thread to drive the probe to move axially, thereby realizing the extension and retraction of the probe.

[0011] In one specific implementation, the push-pull component includes a magnetic rod and a coil. The coil is fixedly connected to the inner wall of the probe rod, the magnetic rod movably passes through the coil, the magnetic rod is electromagnetically connected to the coil, the top end of the magnetic rod is fixedly connected to the clamp, and the tail end of the magnetic rod is fixedly connected to the wire.

[0012] In the above process, a positive or negative current is passed through the coil to push the magnetic rod to extend or retract, which in turn drives the chuck to retract or extend, realizing the clamping, retracting and opening actions.

[0013] In one specific implementation, the lead wire mechanism includes a movable pulley and a fixed pulley. The movable pulley is elastically connected to the probe rod, and the fixed pulley is fixedly installed at both ends of the probe rod. The wire is wound around one of the fixed pulleys and one of the movable pulleys.

[0014] In the above process, the wire is wound in an S-shape around the movable pulley and the fixed pulley. A spring is installed on the movable pulley and connected to the probe rod 20. The spring pulls the wire through the movable pulley, which plays a tensioning role on the wire, avoids the wire from being tangled and messy, and ensures that the probe rod can extend and retract smoothly.

[0015] In one specific implementation, the lead wire mechanism further includes an arc-shaped tube, which is fixedly connected to the tail end of the probe rod, and the wire passes through the arc-shaped tube and is fixedly connected to the base.

[0016] In the above process, the arc-shaped tube is used to guide the wire to the base, and then the mechanical arm leads the wire to the testing equipment.

[0017] In one specific implementation, the base is provided with an installation interface for connection to the robotic arm.

[0018] In the above implementation process, the installation interface is a flange structure, which is used for stable connection with the robotic arm.

[0019] In one specific implementation, the chuck has a three-jaw structure, with the lower ends of the three jaws fixed together. The jaws are made of elastic material, and the outer ends of the jaws abut against the inner wall of the probe rod.

[0020] In the above process, when the gripper extends the probe rod, the three grippers open due to elasticity. Then the probe rod continues to extend forward while the push-pull component pulls the gripper back, so that the gripper clamps the object to be tested. The channel wire transmits the potential back to the detection equipment to achieve lightning protection detection.

[0021] Compared with the prior art, the beneficial effects of this application are: the driving component drives the probe rod to be inserted deep into the equipment, and the push-pull component pushes out the clamp retracted in the probe rod. The clamp opens under the action of elasticity so as to hold the point to be tested, thereby facilitating lightning protection testing deep inside the equipment. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0029] Please see Figures 1-4This application provides a robotic arm device for lightning protection testing, including a base 10 mounted on the front end of the robotic arm. A probe 20 is slidably connected through the base 10. A driving component 30 is provided on the base 10 to drive the probe 20 to move axially. An elastic clamp 40 is provided inside the head end of the probe 20. A push-pull component 50 is provided inside the probe 20 to drive the clamp 40 to retract or extend. A wire 60 is fixedly connected to the rear end of the clamp 40 to connect with lightning protection testing equipment. A lead wire mechanism 70 is provided inside the probe 20 to be adapted to the wire 60. The driving component 30 drives the probe 20 to be inserted deep into the equipment. The push-pull component 50 pushes out the clamp 40 retracted inside the probe 20. The clamp 40 opens under the action of elasticity to hold the point to be tested, thereby facilitating lightning protection testing deep within the equipment.

[0030] Please see Figures 1-4 The driving component 30 includes a worm gear 31 and a worm 32, both of which are rotatably connected to the base 10. The worm gear 31 and worm 32 mesh, and the worm gear 31 is threadedly connected to the probe 20. The driving component 30 also includes a motor 33, which is mounted on the base 10. The output end of the motor 33 is fixedly connected to the worm 32. In this embodiment, the probe 20 has a square cross-section and can only slide axially with the base 10, but cannot rotate. The motor 33 drives the worm 32, which in turn drives the worm gear 31 to rotate. Through the threaded connection between the worm gear 31 and the probe 20, the probe 20 is driven to move axially, thus realizing the telescopic movement of the probe 20.

[0031] Please see Figures 1-4 The push-pull component 50 includes a magnetic rod 51 and a coil 52. The coil 52 is fixedly connected to the inner wall of the probe 20. The magnetic rod 51 movably passes through the coil 52 and is electromagnetically connected to the coil 52. The top end of the magnetic rod 51 is fixedly connected to the clamp 40, and the tail end of the magnetic rod 51 is fixedly connected to the wire 60. A positive or negative current is passed through the coil 52, which pushes the magnetic rod 51 to extend or retract, thereby driving the clamp 40 to retract or extend, realizing the clamping, retracting, and opening actions.

[0032] Please see Figures 1-4 The lead wire mechanism 70 includes a movable pulley 71 and a fixed pulley 72. The movable pulley 71 is elastically connected to the probe rod 20, and the fixed pulley 72 is fixedly installed at both ends of the probe rod 20. The wire 60 is wound around the two fixed pulleys 72 and one movable pulley 71. The wire 60 is wound in an S-shape around the movable pulley 71 and the fixed pulley 72. The movable pulley 71 pulls the wire 60 taut, which prevents the wire 60 from becoming tangled and ensures smooth extension and retraction of the probe rod 20. In this embodiment, the wheel frame of the movable pulley 71 is also axially slidably connected to the inner wall of the probe rod 20 to avoid radial swaying.

[0033] Please see Figures 1-4The lead-in mechanism 70 also includes an arc-shaped tube 73, which is fixedly connected to the tail end of the probe 20. The lead wire 60 passes through the arc-shaped tube 73 and is fixedly connected to the base 10. The arc-shaped tube 73 is used to guide the lead wire 60 onto the base 10, and then the robotic arm leads the lead wire 60 to the testing equipment.

[0034] Please see Figures 1-4 The base 10 is equipped with a mounting interface for connection to the robotic arm. The mounting interface is a flange structure for stable connection with the robotic arm.

[0035] Please see Figures 1-4 The chuck 40 has a three-jaw structure, with the lower ends of the three jaws fixed together. The jaws are made of elastic material, and the outer ends of the jaws abut against the inner wall of the probe rod 20. When the jaws extend out of the probe rod 20, due to the elasticity, the three jaws open. Then, the probe rod 20 continues to extend forward while the push-pull component 50 pulls the chuck 40 back, causing the jaws to clamp the object to be tested. The channel wire 60 transmits the potential back to the detection equipment to achieve lightning protection detection. In this embodiment, the lower end of the chuck 40 is provided with a limiting groove structure on the inner wall of the probe rod 20 to achieve circumferential fixation and axial sliding, so as to avoid rotation during retraction.

[0036] The working principle of this robotic arm device for lightning protection detection is as follows: When encountering a narrow gap, coil 52 first pulls magnetic rod 51, which in turn retracts clamp 40 into probe 20. Then, motor 33 drives worm gear 32, which in turn drives worm wheel 31 to rotate. Through the threaded connection between worm wheel 31 and probe 20, probe 20 is driven to move forward. When it reaches the point to be measured, coil 52 pushes magnetic rod 51 out. When the clamps extend out of probe 20, due to elasticity, the three clamps open, and then probe 20 continues to move forward. Simultaneously, the push-pull component 50 pulls the clamp 40 back, causing the clamp 40 to hold the object to be tested. The channel wire 60 transmits the potential back to the testing equipment to achieve lightning protection testing. After the test is completed, the clamp 40 can be opened and then retracted. In summary, the driving component 30 drives the probe 20 to be inserted deep into the equipment, and the push-pull component 50 pushes out the clamp 40 retracted in the probe 20. The clamp 40 opens under the action of elasticity to hold the point to be tested, thus facilitating lightning protection testing deep inside the equipment.
