A water conservancy engineering pipeline outer surface rust removal device

Abstract

The invention discloses a derusting device for the outer surface of a water conservancy pipeline, which belongs to the technical field of derusting the water conservancy pipeline. A device for removing rust on the outer surface of pipelines in water conservancy projects, including a rust removal platform, a clamping assembly is arranged inside the top of the fixed seat, an adjustment column is connected to the upper side of the outer wall of the rotating ring through a pin shaft, and an adjustment handle B is threaded inside the adjustment column , there is a ring frame in the middle of the outer side of the rotating ring. The inside of the ring frame is circular and equally spaced and connected with a plurality of mouth-shaped limit blocks through the rotation of the pin shaft. The inside of the mouth-shaped limit block is slidingly connected with a clamping block. There are engineering pipelines to be treated, and the close cooperation between the structures enables the device to clamp and derust engineering pipelines of different thicknesses, avoiding the situation that the rust cannot be derusted due to the limitation of the fixed structure, expanding the scope of derusting and improving Improve the clamping effect of the engineering pipeline to be treated, avoid the phenomenon of falling during the derusting process, and ensure the derusting quality of the engineering pipeline to be treated.

Description

technical field [0001] The invention relates to the technical field of rust removal of water conservancy pipelines, and more particularly to a rust removal device for the outer surface of water conservancy engineering pipelines. Background technique [0002] A water conservancy project is a project built for the purpose of controlling and deploying surface water and groundwater in nature to achieve the purpose of eliminating harm and benefiting, also known as water project. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent flood disasters, and adjust and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, embankments, spillways, sluice gates, water inlets, channels, ferr...

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
