Embodiment 1

[0036] Such as figure 1 , 2 As shown, an outdoor knife switch maintenance device provided by an embodiment of the present invention is used for performing non-stop maintenance on the knife switch of outdoor power equipment, including a support base, a lifting part fixedly connected to the support base, and the lift The maintenance part of the internal thread fit, maintenance includes cleaning the accumulated dust and surface rust on the knife switch equipment and adding lubricating oil.

[0037] Multiple embodiments of the present invention The outdoor knife gate maintenance device provided in the embodiments includes a maintenance part.

[0038] In this embodiment, specifically, as attached figure 1 As shown, the maintenance part includes a mobile platform 9, a lubricating oil pump 17 is arranged on the left end of the upper surface of the mobile platform 9, and a blower 10 is arranged on the right end thereof. Lubricating oil pump 17 and air blower 10 are fixed on the mob...

Embodiment 2

[0045] as attached Figure 3-6 The difference between this embodiment and the above-mentioned first embodiment is that the outdoor knife switch maintenance device of this embodiment further includes a supporting base 1 and a lifting part. Four universal wheels are arranged on the lower surface of the support base 1 . The lifting part is arranged on the upper surface of the supporting base 1 . The lifting part includes a lifting motor 2, a vertical ball screw 3, a lifting table 4, a moving motor 5 and a horizontal ball screw 18.

[0046] In this embodiment, there are two lifting motors 2 and two vertical ball screws 3 , and the lifting motors 2 are respectively arranged in the middle of the left and right sides of the upper surface of the support base 1 . The lifting motor 2 is vertically arranged, and its lower end is fixed on the support base 1 with bolts. The vertical ball screw 3 is arranged on the upper end of the lifting motor 2 . A lifting table 4 is arranged on the ...

Abstract

An outdoor knife switch maintenance device, comprising a supporting base, a lifting part fixedly connected with the supporting base, and a maintenance part screwed with the lifting part; the maintenance part includes a mobile platform, a An electric lifting rod, and a telescopic rod hinged with the electric lifting rod, a lifting platform is arranged on the supporting base, a mobile platform is arranged on the lifting platform, and a telescopic rod and a flexible pipe are arranged on the mobile platform. When the present invention maintains the knife switch, only the telescopic rod and the flexible pipe are in contact with the knife switch, so the material of the telescopic rod is insulating ceramics, and the material of the flexible pipe is insulating material. Therefore, during maintenance, the power equipment does not need to be powered off. Another part of the maintenance department includes lubricating oil and lubricating oil pump. After the dust and surface floating rust accumulated on the knife switch are blown clean, this part will work again. After the lubricating oil flows out of the lubricating oil pump, it flows through the pipeline to the position required by the knife switch. The whole process does not require manual dust removal, rust removal, and lubrication, which is safe and reliable.

Description

technical field [0001] The invention relates to a maintenance device for electric equipment, in particular to an outdoor knife switch maintenance device. Background technique [0002] Knife switch generally refers to a high-voltage disconnector, that is, a disconnector with a rated voltage of 1kV and above, usually referred to as a disconnector, and is the most widely used high-voltage switchgear. Its working principle and structure are relatively simple. However, due to the large amount of use and high reliability requirements, it has a greater impact on the design, establishment and safe operation of substations and power plants. [0003] With the development of the national economy, the power industry is also developing rapidly, but the growth of the number of employees in power companies is far behind the development of the power system and the growth of equipment, and regular maintenance requires a lot of manpower and material resources, which can no longer satisfy the ...
