Problems solved by technology

Due to the complex internal structure of large power equipment, very small available space, and many bends, inspection points that are difficult for human eyes to see and maintenance personnel's arms to penetrate are often encountered during maintenance.
When the fault cannot be eliminated by conventional methods on site, the equipment needs to be repaired by the suspension cover
The hanging hood has heavy workload, high cost and long power outage time

Embodiment

[0025] like figure 1 and figure 2 As shown, a mechanical arm for power transformer maintenance, which includes a telescopic rod assembly, a first joint assembly, a second joint assembly and an extension arm connected sequentially from the rear end to the front end, as well as lighting LED14, control switch 2, endoscope 17 and flush oil pipe 18. The extension arm includes an upper extension arm 15 and a lower extension arm 16, which respectively correspond to the double-hole structure inside the mechanical arm. Pass through the telescopic rod assembly, the second joint assembly, the first joint assembly, and then stretch out from the upper extension arm 15 and the lower extension arm 16 respectively. The lighting LED 14 is arranged at the front end of the mechanical arm, and as a probe lighting source, it can help the operator go deep into the equipment without light, and improve the detection brightness of the endoscope at the same time.

Abstract

The invention relates to a mechanical arm device for power transformer maintenance. The device comprises a telescopic rod assembly, a second joint assembly, a first joint assembly, an extending arm, an endoscope and a detecting and maintenance tool, wherein the telescopic rod assembly, the second joint assembly, the first joint assembly, and the extending arm are sequentially connected from the rear end to the front end, and the endoscope and the detecting and maintenance tool sequentially penetrate through the telescopic rod assembly, the second joint assembly, the first joint assembly, the extending arm from the rear end to the front end. An illumination light-emitting diode (LED) is arranged at the front end of the mechanical arm, and a control switch used for controlling the first joint assembly and the second joint assembly is arranged at the rear end of the mechanical arm. Compared with the prior art, the mechanical arm device for power transformer maintenance is simple, light and handy in structure, good in expandability, double in degree of freedom, flexible to rotate, and applicable to manual operation expanding tools in large power equipment (transformers) maintenance works.

Description

technical field [0001] The invention relates to a device for overhauling large electric equipment, in particular to a mechanical arm device for overhauling a power transformer. Background technique [0002] Large power transformers and switches are extremely important parts of the power supply system, and they often generate abnormal heat during operation. Due to the complex internal structure of large power equipment, very small available space, and many bends, inspection points that are difficult for human eyes to see and maintenance personnel's arms to penetrate are often encountered during maintenance. When the fault cannot be eliminated by conventional methods on site, the equipment needs to be repaired by the suspension cover. The hanging cover has a large workload, high cost, and long power outage time. Contents of the invention [0003] The purpose of the present invention is to provide a special mechanical arm with simple operation, good expandability, double de...
