Water conservancy project pipeline outer surface rust removal device

Abstract

The invention discloses a water conservancy project pipeline outer surface rust removal device, and belongs to the technical field of water conservancy pipeline rust removal. The water conservancy project pipeline outer surface rust removal device comprises a rust removal platform. Clamping assemblies are arranged in the upper portions of fixing bases. Adjusting columns are rotatably connected to the upper sides of the outer walls of rotating rings through pin shafts, adjusting handles B are connected inside the adjusting columns through threads, and annular frames are arranged in the middles of the outer sides of the rotating rings. A plurality of mouth-shaped limiting blocks are annularly and rotatably connected inside the annular frames at equal intervals through pin shafts, clamping blocks are slidably connected inside the mouth-shaped limiting blocks, and a to-be-treated project pipeline is clamped on the inner sides of the clamping blocks. Through close fit between the structures, the device can conduct clamping and rust removal on project pipelines with different thicknesses, the situation that rust removal cannot be achieved due to the limitation of a fixing structure is avoided, the rust removal range is expanded, the clamping effect on the to-be-treated project pipeline is improved, the phenomenon of falling in the rust removal process is avoided, and the quality of rust removal on the to-be-treated project pipeline is guaranteed.

Description

Technical field[0001]The present invention relates to the field of water conservancy pipe rust, and more particularly to the outer surface rusting device of water conservancy engineering pipeline.Background technique[0002]Water conservancy projects are used to control and distribute surface water and groundwater to naturally, and the projects built to remove the purpose of conjugation are also known as water projects. Water is a valuable resource for human production and life, but its natural state is not fully in line with human needs. Only the construction of water conservancy projects can control water, prevent flood disasters, and regulate and distribute water volume to meet the needs of people's lives and production on water resources. Water conservancy projects need to build dams, dysfunction, spillways, water gates, water ports, channels, ferry, raft, fish and other different types of hydraulic buildings to achieve their goals. According to the purpose or service objects, it ...

Problems solved by technology

The document of prior art publication number CN210024837U provides a kind of derusting device for the outer surface of water conservancy pipeline, which device can make the Pipeline rotation, by being provided with slide block, first hydraulic rod, first hydraulic cylinder and connecting rod, can make derusting wheel move along the length direction of pipeline, achieve the purpose of derusting with derusting wheel, although the beneficial effect of this device is relatively However, there are still the following problems: the fixed structure provided by the device cannot fix engineering pipelines of different thicknesses, that is, the device can be used in a narrow range and cannot derust engineering pipelines of different thicknesses, and the device uses the derusting wheel to clean the pipelines. Derusting, the derusting effect is poor, the efficiency is low, it will cause the surface of the engineering pipeline to derust with alternating traces of rust and no rust, if it is repeated for the purpose of derusting, the outer wall of the engineering pipeline will appear uneven in thickness In addition, other existing patented technologies cannot realize the adjustable pressure of derusting, and it is impossible to realize automatic and continuous derusting for engineering pipelines with special-shaped auxiliary structures. The rust knife moves to the irregular place and stops, then manually skips the irregular place and continues to derust the remaining pipelines. In view of this, we propose a derusting device for the outer surface of hydraulic engineering pipelines
