Problems solved by technology

[0003] For the current large drilling tools, more auxiliary equipment needs to be carried, and the amount of maintenance is relatively large. However, the simple drilling method uses more tools and is prone to eye distance deviation, and the deviation of the drill bit is likely to cause injury to people and tools. , the invention provides a portable auxiliary drilling tool, which can not only solve the complex and cumbersome use, but also solve the problems of eye distance deviation, injury to people and tools

Embodiment Construction

[0030] Such as Figure 1 to Figure 5 As shown, the portable auxiliary drilling tool includes a long ruler 100 and a short ruler 200, wherein the short ruler is inserted into the long ruler.

[0031] The long chi and the short chi are provided with a number of drilling holes to facilitate the positioning of the drilling holes, and the long chi and the short chi are also provided with scales for convenient and accurate drilling positions.

[0032] Such as figure 2 As shown, a stop plate 12 and a rear limit plate 13 are also provided on the long ruler. The stop plate uses the side of the bus bar to slide and fit, and always moves along the bus bar. Slot 14 is provided to facilitate the insertion of a short ruler, such as figure 1 It is the state diagram when the short ruler is inserted into the long ruler.

[0033] There is a busway between the stop plate and the rear limit plate. Because the busbar is divided into copper and aluminum, according to the structural characterist...

Abstract

The invention discloses a portable auxiliary drilling tool, and relates to the technical field of electrical equipment. The portable auxiliary drilling tool comprises a long ruler and a short ruler, the short ruler is connected with the long ruler in an inserted mode, a plurality of drilling holes are formed in the long ruler and the short ruler, scales are further arranged on the long ruler and the short ruler, a blocking plate and a rear limiting plate are further arranged on the long ruler, the blocking plate is in moving sliding fit along the edge side of a busbar, slots for facilitating insertion of the short ruler are formed in the blocking plate and the rear limiting plate, and a busway is formed between the blocking plate and the rear limiting plate. The portable auxiliary drilling tool is small in size, low in weight and easy to carry, namely the problems of busbar fixing, hole span deviation, people wounding, equipment damage are solved, and reasonable combination of the tool is achieved. Hole drilling by maintenance staff in the process of busbar maintaining is thoroughly and effectively achieved, and the correct rate of hole drilling is 90%.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a portable auxiliary drilling tool. Background technique [0002] During the maintenance work of the busbar over the years, when the busbar is newly installed or replaced, it is often necessary to drill the busbar. There are two drilling methods: one is a large hydraulic or electric drilling tool, which is complicated to use and not easy to transport. The perforating tools need to carry more auxiliary equipment, and the amount of maintenance is also relatively large. At the same time, the power outage of the whole station needs to be considered. The other is a simple method of scribing, positioning, and pistol drilling. Due to the smooth surface of the busbar, the simple drilling method requires more tools during operation, and the problem of eye distance deviation is prone to occur. The deviation of the drill bit is likely to cause injury, Injury incidents. Content...
