Embodiment approach

[0032] Such as Figure 2 to Figure 4 As shown, in this embodiment, the lower support frame 202 includes a lower beam 212, a lower support cylinder 232 and two reinforcing rods 242. As a preferred embodiment of the present invention, the lower beam 212 is cylindrical, Both ends of the lower beam 212 are respectively provided with adjustment holes 252 . The adjusting hole 252 is a threaded hole. The bottom of the lower beam 212 is symmetrically fixed with upper universal rollers 222, and the upper universal rollers 222 are used to enhance the mobility of the lower beam 212 so as to adjust the position of the lower beam 212 according to the needs of the terrain. The lower end of the lower support tube 232 is fixed on the lower beam 212. As a preferred embodiment of the present invention, the lower support tube 232 is in the shape of a rectangular tube, and the lower support tube 232 is provided with three or more outer tubes at intervals along the height direction. Jack 262. T...

Abstract

The invention belongs to the technical field of conveying tools, and particularly relates to a conveying tool for a withstand voltage test instrument of ultrahigh-voltage electrical equipment. A loading vehicle and a lifting assembly are included, the lifting assembly comprises two upper supporting frames, two lower supporting frames and a lifting device, the two lower supporting frames are symmetrically arranged and fixedly connected through a connecting rod, leveling devices are symmetrically installed at the bottoms of the lower supporting frames, the lower ends of the upper supporting frames are inserted into top end openings of the lower supporting frames, the upper supporting frames and the lower supporting frames are fixed through locking bolts, and the lifting device is installed on the upper supporting frames in a sliding mode. The conveying tool has the advantages of being complete in use function and suitable for special terrains, the lifting device and the loading vehicle are used in cooperation, the carrying function is achieved, meanwhile, the test instrument is supported to be lifted, the problems that an existing conveying tool is limited in use function and difficult to work under the special terrains are solved, and the use requirement of an electric power system is met.

Description

technical field [0001] The invention relates to a delivery tool, in particular to a delivery tool used for an ultra-high voltage electrical equipment withstand voltage test instrument. Background technique [0002] Ultra-high voltage electrical equipment is a common electronic equipment in the power system. In order to ensure the safety and reliability of the power system during operation, a series of maintenance and tests need to be carried out, including AC withstand voltage tests of 220kV and above electrical equipment, and transformer error testing. test. During the test, because the electrical equipment and the test instrument are usually not in the same area, it is necessary to transfer the test instrument to the vicinity of the equipment, taking into account the volume and weight of the test instrument, and ensuring the stability of the test instrument during transportation. To prevent its accuracy from being affected, it is necessary to use transportation tools to t...
