Adjustable-inner-diameter construction steel pipe cleaning device

Abstract

The invention discloses an adjustable-inner-diameter construction steel pipe cleaning device. Worms are engaged with worm gears correspondingly. The rear portions of the worm gears are fixedly connected with the centers of regulating devices correspondingly. The worm gears and the regulating devices are rotationally connected with a transverse plate. The upper end of a driving shaft is fixedly connected with a third bevel gear. A fourth bevel gear is in rolling connection with the right end of a conveying belt. The rear portion of a belt pulley is rotationally connected with the back of a device body, and the front end of the belt pulley is fixedly connected with a rotary shaft. The front end of the rotary shaft is fixedly connected with a steel wire brush roll. Bearings on the upper portions of the regulating devices are rotationally connected with lead screws correspondingly. The lead screws are in threaded connection with sleeve blocks correspondingly. The two ends of the sleeve blocks are in sliding connection with guide grooves correspondingly. According to the device, a bevel gear set drives the belt pulley to rotate so as to drive the steel wire brush roll to rotate for cleaning, clamping rings are used for clamping a steel pipe, so that the interior of the steel pipe rotates around the steel wire brush roll for cleaning and brushing, the sleeve blocks are driven to moveup and down by rotating the lead screws, accordingly, the diameter of circular motion of the steel pipe is regulated, and steel pipes with different inner diameters can be cleaned and brushed. The device is reasonable and applicable in structural design, capable of adapting to the steel pipes with the different pipe diameters, and high in flexibility.

Description

technical field [0001] The invention relates to a construction machine, in particular to a construction steel pipe cleaning device with an adjustable inner diameter. Background technique [0002] With the rapid development of my country's construction industry, the use of construction steel pipes continues to increase, and construction steel pipes can be divided into seamless steel pipes and seamed steel pipes according to whether they are seamed or seamless. Seamed steel pipes are divided into spiral steel pipes and straight seam steel pipes according to the different welds. The two are widely used in construction piling, structure, steel structure, load-bearing, drainage and other aspects. Steel pipe materials mainly include carbon steel, stainless steel, and alloy steel, among which carbon steel is the most commonly used. [0003] The construction steel pipes are stacked on the construction site for a long time without being exposed to the wind and the sun to form oxide ...

AI Technical Summary

Problems solved by technology

[0003] Construction steel pipes are piled up on the construction site for a long time and have not been used for a long time to form oxide layers, iron filings and other impurities on the surface. If they are not cleaned up in time, they will easily affect the service life of the steel pipes.

[0004] At present, most of the existing construction steel pipe cleaning devices can only clean the outer wall of the steel pipe. The cleaning of the inner wall of the steel pipe requires the use of a fixed type of brush head corresponding to the inner diameter of the steel pipe. The cleaning effect is not good, which greatly limits the flexibility of cleaning the inner wall.
