Description

Supporting device for moving trolley of live-line maintenance robot

Technical Field

The utility model relates to a power supply system overhauls the equipment field, specifically is a robot travelling car strutting arrangement is overhauld in electrified.

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 live working robots have been developed in China, the transport trolley at the bottom of the robot is prone to toppling due to the fact that the weight of the overhaul tool is large. Several types of electric operation robots which are disclosed at present cannot move freely in a transformer substation due to large size, heavy weight and the like.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve prior art's problem, provide a live overhaul robot travelling car strutting arrangement, through the strutting arrangement that can receive and release fixing the dolly at the during operation, reduced the volume of dolly, strengthened the stability of overhauing the robot during operation.

The utility model comprises a plurality of stages of support columns which are connected through revolute pairs, each stage of support column is of a telescopic rod structure and comprises an outer rod and an inner rod which are of concave structures, and a driving motor and the inner rod are nested in a concave groove of the outer rod; the inner rod is connected with a driving motor through a driving rod, and the driving motor pushes the inner rod to slide along the slide way in the concave groove of the outer rod through the driving rod; in the adjacent two-stage support column, the outer pole of each stage support column is connected with the inner pole of the upper stage support column through the revolute pair, and the outer pole is clamped into the concave groove of the inner pole of the upper stage support column when rotating through the revolute pair.

The support device is distributed around the movable trolley, a support rod accommodating area is arranged on the trolley, and the support column is contracted in the support device accommodating area of the movable trolley in a non-overhaul state; under the maintenance state, the support column rotates out from the storage area, and the movable trolley is fixed with the ground.

The utility model has the advantages that:

1. the trolley is fixed by the retractable supporting device during working, so that the size of the trolley is reduced, and the working stability of the maintenance robot is enhanced.

2. The supporting column of the supporting device can be folded in a multi-stage telescopic mode, the inside of the moving trolley can be completely folded in a non-maintenance state, the space is saved, and the moving trolley can be conveniently moved in a transformer substation.
