Problems solved by technology

[0003] However, construction steel pipes are prone to rust during long-term use. Most of the existing construction steel pipe derusting devices are simple in structure and can be used to derust the outside of the steel pipe. It is very difficult to derust the inner wall of the steel pipe, so the existing construction steel pipe derusting device has the problem that it is not convenient to derust the inner wall of the steel pipe

Abstract

The invention discloses a rust-removal device for the inner wall of a construction steel pipe, and relates to the technical field of construction devices to mainly solve the problem that rust stains on the inner wall of the steel pipe are inconvenient to clear away through an existing rust-removal device for the construction steel pipe. The rust-removal device for the inner wall of the construction steel pipe comprises a base; a first support is fixedly mounted on the left side of the upper surface of the base, and a first motor is fixedly mounted on the first support; the output end of the first motor is fixedly connected with a first rotary shaft, and one end of the first rotary shaft is fixedly connected with a movable rod; a connecting shaft is fixedly mounted on the reverse side of the end, away from the first rotary shaft, of the movable rod; a first sliding rail is further fixedly mounted on the left side of the upper surface of the base, and a first sliding block is slidably arranged in the first sliding rail; a supporting rod is fixedly connected to the upper side of the first sliding block, a sliding plate is fixedly mounted on the upper side of the supporting rod, and one end of the connecting shaft is slidably connected into a slideway in the sliding plate; and the right side of the sliding plate is fixedly connected with a connecting rod, and one end of the connecting rod is fixedly connected with a brush.

Description

technical field [0001] The invention relates to a construction device, in particular to a derusting device for the inner wall of a construction steel pipe. Background technique [0002] The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of petroleum in the early 19th century, and the manufacture of ships, boilers, and aircraft during the two world wars. Steel pipes are not only used to transport fluids and powdery solids, exchange heat, and manufacture machinery. Parts and containers; steel pipe is also a kind of economical steel. Using steel pipe to manufacture building structure grids, pillars and mechanical supports can reduce weight and realize factory-like mechanized construction. Manufacturing road bridges with steel pipes can not only save steel, simplify construction, and It can greatly reduce the area of ​​the protective layer, saving investment and maintenance costs. [0003] However, cons...
