Scraping device of insulating telegraph pole

Abstract

The invention discloses a scraping device of an insulating telegraph pole. The device comprises a rack, a die cylinder, a feed pipe, a rotary cover, a compressed spring, a scraper, a hollow shaft, a nut, a belt pulley, and a machine body. The machine body is arranged on the rack. One end of the hollow shaft extends out of the machine body, and the scraper is fixed on one end of the hollow shaft. The hollow shaft is provided with the belt pulley. The left side of the belt pulley is provided with a round nut. The round nut is screwed in threads on the shaft to realize fastening. One side of thescraper is provided with a cylindrical die cylinder. The outer end of the die cylinder is screwed with the round rotary cover. The feed pipe is connected between the die cylinder and the rack. The scraping device effectively ensures good coaxiality of the insulating telegraph pole and a scraper axis, and can scrape oxide skin on the surface of the insulating telegraph pole in high speed, and feedspeed of the insulating telegraph pole is fast, and thickness of cut surface scale is uniform.

Description

technical field [0001] The invention relates to a scraping device, in particular to a scraping device for insulating poles used in the electric power industry. Background technique [0002] There are several ways to remove the oxide layer on the surface of the known alloy pole disc: 1. Peeling die: with a certain peeling and cutting cone angle, the two ends of the peeling die are positioned and guided, and under the traction of the front-end power, the metal rod is continuously The surface is peeled, and the surface of the metal rod is in a pure state after peeling. The disadvantage of this method is that it requires a lot of traction when peeling, and it leads to the limitation of the production process. 2. Mechanical scrubbing process: In this method, before scrubbing, the metal rod is first pulled to remove the oil film on the surface, soaked in lye, washed with water, dried, and then scrubbed with a wire brush. The disadvantage of this method is that the steel wire bru...

Problems solved by technology

The disadvantage of this method is that it requires a lot of traction when peeling, and it leads to the limitation of the production process.

The disadvantage of this method is that the steel wire brush wears quickly and the mechanical failure rate is high. During the scrubbing process, the heat generated by the friction between the metal rod and the brush will cause the surface of the metal rod to re-form an oxide layer, and at the same time, the friction will generate electrostatic adsorption of dust, and The mechanical noise is large, which has a great impact on the surface quality of the metal rod after brushing

At the same time, because the scraper is not durable, it will collapse after a period of use, with poor durability and low scraping speed
