Description
Technical Field
The utility model relates to a field specifically is a rotatory davit in electrified machine people top of examining and repairing.
Background
With the development of national economy, the power industry is rapidly developed, but the increase of the number of the employees of the power enterprise is far from the development of a power system and the increase of equipment, and a large amount of manpower and material resources are required to be invested in the regular maintenance, so that the requirements of power system reformation and man-saving and efficiency improvement cannot be met. The development of a power grid faces the requirements of high power supply reliability, high load density and high power quality, the requirements of users on power failure time are more and more strict, the power failure of important key lines is difficult to arrange, and the power failure maintenance opportunities are less and less.
The pollution flashover phenomenon easily occurs to power plants, transformer substations and booster station equipment in long-term operation, so that the grounding accidents of the power system are frequent, and the safe operation of the power system is seriously influenced; in order to prevent accidents such as power failure caused by pollution flashover of equipment such as insulators, switches and disconnecting links, the magnetic columns, the CT and the PT must be cleaned regularly to maintain the switches and the disconnecting links. In the maintenance process, the functions of dismounting the drainage wire, lifting the manned drainage wire and the like are required to be realized.
According to the regulations of preventive test procedures of electrical equipment: the period of the metallic zinc oxide arrester pressure test is one year. And regulations should be made before the thunderstorm season each year. For newly-put-into-operation metal zinc oxide lightning arresters with the voltage level of 110KV and above, an alternating current leakage current test is carried out 3 months after the lightning arresters are put into operation, and then the test is carried out once every half year. After the operation is normal, the test is carried out before the thunderstorm season every year. The drainage wire is taken to the maintenance test of arrester needs to be torn open, and present actual operation process is only maintained and is tested when having a power failure, and test period is all surpassed to the vast majority arrester, has great potential safety hazard.
The insulating ladder of power plant, transformer substation use as the instrument of ascending a height more, and insulating ladder length is longer, and weight is big, uses very inconveniently.
For the two situations, most of the existing working modes adopt a power failure operation mode, however, with the improvement of the requirement of power users on the reliability of power supply, the reduction of the times of power failure maintenance of the transformer substation is very important.
Therefore, the power grid has a very urgent need for advanced live overhaul operation technology. However, because of the problems of high voltage level, dense equipment in the substation, large volume and weight of the equipment and the like, the development of manual live working has great difficulty, and the application of the robot technology can effectively solve the problems.
Although various types of electric operating robots have been developed in China, several types of electric operating robots which are disclosed at present still need to be lifted to the periphery of an electric operating line by an operator in an insulating bucket of an insulating bucket arm vehicle or a machine arm outside the insulating bucket because of the reasons of large size, heavy weight, electric insulating performance which does not reach the electric operating standard and the like in the process of electric operating, and potential risks still exist, so that personal risks can be brought to the operator.
If the unmanned live-line work of the live-line maintenance robot is realized through remote control and remote measurement, the live-line maintenance robot needs to be improved urgently, and particularly, the structure of the top rotating suspension arm has to have functional diversity so as to meet various problems in the actual maintenance process.
