Tool for cleaning inner wall of concrete tubular pile die

Abstract

The invention discloses a tool for cleaning the inner wall of a concrete tubular pile die. The tool comprises a supporting vehicle body, a cleaner, an electromotor and a transmission mechanism. The cleaner is fixedly hung near the supporting vehicle body, the electromotor is fixedly installed on the supporting vehicle body, the cleaner comprises a rotary plate, a plurality of steel wire brushes are arranged on the outer edge of the rotary plate at intervals, the electromotor is connected with a rotary shaft through the transmission mechanism, and the rotary shaft is fixedly connected with the middle of the rotary plate of the cleaner. When the supporting vehicle body moves along the die, the cleaner is right arranged in the die, the electromotor drives the cleaner to rotate, and therefore the steel wire brushes on the cleaner brush away concrete blocks on the inner wall of the die. The tool for cleaning the inner wall of the concrete tubular pile die is simple and efficient, can clean the concrete blocks on the inner wall of the steel die easily and is ideal in cleaning effect, thereby greatly reducing labor intensity, improving labor efficiency and improving the production speed.

Description

【Technical field】 [0001] The invention relates to a tool in the construction industry, in particular to a tool for cleaning the inner wall of a concrete pipe pile mold. 【Background technique】 [0002] There are 700 prestressed concrete production enterprises in my country, and the annual output exceeds 400 million meters. It is the country with the most production and application of prestressed concrete in the world. Since the molds for producing prestressed concrete pipe piles are steel molds, each steel mold needs to produce 3 piles every day, and it takes an average of 8 hours to turn over the mold and reuse it. After the steel mold comes into contact with the concrete, it will produce a slight sticky skin. After using each steel mold for 2 months, the outer wall of the produced pile has 5-8mm deep cement blocks peeling off. Round-trip freight, the waste of the company's backlog of inventory and the decline of products in the market. [0003] In order to ensure the appe...

Problems solved by technology

After the steel mold comes into contact with the concrete, it will produce a slight sticky skin. After using each steel mold for 2 months, the outer wall of the produced pile has 5-8mm deep cement blocks peeling off. Round-trip freight, the waste of the company's inventory backlog and the decline of products in the market

[0003] In order to ensure the appearance of the pipe pile is round and smooth, the pipe pile industry currently adopts traditional treatment methods to repair the sticky skin of the steel mold mainly in the following two ways: 1. Inject about 1.5 tons of 30mm steel balls into the steel mold and then hoist it into the centrifuge at a medium speed. Centrifugal, this method is noisy and slow, can't finish grinding every day for 365 days, and there are many complaints

2. After 2 months of production, 3 shifts were shut down, and 50 people in each shift were manually polished with a grinder for 12 hours. The cost was too high, and there were many safety hazards for employees during operation.
