Description

Technical Field

[0001] The present invention relates to the field of elevator fault detection, and in particular to a device for detecting and testing a simulated elevator grounding fault. Background Art

[0002] Grounding faults can be caused by equipment aging, improper maintenance, or grounding failure. As elevators age and the environment changes, the insulation inside some elevator equipment may age, become damaged, or corrode, leading to equipment grounding problems. Failure to perform insulation testing or grounding inspections during maintenance, or to adhere to standard operating procedures, can also lead to grounding faults. The hazards of grounding faults include: A grounding fault can increase the voltage in the elevator equipment, reducing its safety. In some cases, grounding problems can also cause serious accidents such as fires.

[0003] The methods for detecting elevator grounding faults mainly include the following: Multimeter test method: Test steps: Set your multimeter to the resistance setting (usually 200MΩ). Connect the red test lead to the elevator ground wire and the black test lead to the ground or another known grounded metal component. Observe the multimeter reading. If the resistance is close to infinity, the ground wire is de-energized. If the resistance is low, the ground wire is energized.

[0004] ‌Test pencil detection method‌: Test steps: Touch the tip of the tester to the elevator ground wire. Observe the tester's indicator light. If it lights up, the ground wire is live; if it doesn't, it's not live.

[0005] However, the above two detection methods require personnel to conduct close-range detection. Although this detection method can achieve the purpose of detection, it is easy to cause the risk of electric shock due to operational errors. For this reason, we have made improvements and proposed a simulated elevator grounding fault inspection and detection device. Summary of the Invention

[0008] As the preferred technical solution of the present application, the U-shaped clamp seat is made of insulating material, a groove is provided in the middle of the U-shaped clamp seat, and the inner side wall of the groove is rotatably connected to a roller. The setting of the roller can effectively reduce friction, thereby protecting the detection clip and improving the service life of the detection clip.

When the moving direction needs to be changed, the electric push rod three can be extended and retracted to drive the connecting rod to move so that the two moving wheels change the moving direction.

[0012] As the preferred technical solution of the present application, the robotic arm includes a robotic arm shaft seat fixedly connected to the top of the mobile detection machine disk, the inner side wall of the robotic arm shaft seat is rotatably connected to the main arm, one end of the main arm is rotatably connected to the auxiliary arm, one end of the auxiliary arm is rotatably connected to the rotating disk, the side wall of the main arm is rotatably connected to the tripod, one end of the tripod is rotatably connected to connecting rod one, the connecting rod one is rotatably connected to the rotating disk, the other end of the tripod is rotatably connected to connecting rod two, one end of the connecting rod two is rotatably connected to the robotic arm shaft seat, the side wall of the auxiliary arm is rotatably connected to connecting rod three, the robotic arm can realize multi-angle conversion, and facilitate detection.

When turning is required, the turning of the mobile detection base disk can be achieved by the extension and retraction of the electric push rod three. The mechanical arm can be adjusted at multiple angles to move the entire detection component to the detection area. The two detection clips can detect the neutral line and the live line respectively. The mechanical arm moves the two detection clips to the line to be detected. When the electric push rod contracts, the two detection clips are squeezed and deformed by the U-shaped clamp seat, and move inward to fit the line to be detected, thereby realizing automatic voltage detection. Since the U-shaped clamp seat is made of insulating material, it will not introduce current into the entire mechanical equipment, which greatly improves safety. BRIEF DESCRIPTION OF THE DRAWINGS
