Environment-friendly sewage pipeline overhaul and maintenance equipment

Abstract

The invention relates to an environment-friendly sewage pipeline overhaul and maintenance equipment which comprises a fixed base frame. A pull-removal mechanism is arranged on the fixed base frame, and an auxiliary mechanism is arranged at the lower end of the fixed base frame. During existing process of using a crane to remove a pipeline in a pulling mode, the difficult problem a that the pipeline is damaged due to the fact that the outer wall of the pipeline is prone to being deformed because the strength of the pipeline being squeezed by soil plus the weight of the pipeline itself is increased when brute force is applied upwards on the locked pipeline for lifting is solved, the difficult problem b that when the crane is adopted to lift the pipeline, it is necessary to fix the pipeline with the help of fixtures, when working is carried out on different types of pipelines, manual adjustment according to the types of the pipelines is needed, and the stability of manual fixing the pipeline with the fixtures is poor is solved, and the technical problem c that operators are prone to be hit due to the circumstance such as shaking during the process of pulling the pipeline out of soil because the lifted pipeline is prone to sliding downwards is solved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to maintenance equipment for environmental protection sewage pipelines. Background technique [0002] Sewage pipes are commonly used tools in sewage treatment operations. In sewage treatment operations, sewage pipes need to be replaced and repaired regularly. When repairing and replacing sewage pipes, it is necessary to remove the pipes that are vertically inserted into the soil, especially for vertically inserted into the soil. The internal pipes need to use equipment such as cranes to pull out the pipes fixed with clamps from the soil. [0003] However, there are the following problems in the process of using a crane to pull out the pipeline: a. In the traditional pipeline pulling operation, the outside of the pipeline is fixed and locked, and the crane is used to pull it out upwards, and the pipeline is squeezed by the soil. Its own specific gravity in...

Problems solved by technology

[0003] However, there are the following problems in the process of using a crane to pull out the pipeline: a. In the traditional pipeline pulling operation, the outside of the pipeline is fixed and locked, and the crane is used to pull it out upwards, and the pipeline is squeezed by the soil. Its own specific gravity increases, and when the locked pipe is lifted upwards with brute force, it is easy to deform the outer wall of the pipe, resulting in damage to the pipe

b. When using a crane to lift the pipeline, it is necessary to fix the pipeline with the help of clamps. When working on different types of pipelines, it is necessary to manually adjust according to the pipeline model, and the stability of the manual use of clamps to fix the pipeline is poor. There are safety hazards in the lifting and pulling operation, which reduces the efficiency of pipe pulling

c. Due to the different softness of the soil during the extraction of the pipeline, there will be a change in the extraction speed when the pipeline is lifted upwards. The crane adopts the rope traction and stretching method. When the speed changes, the tension of the rope itself will change accordingly. If there is a change, it is easy to cause the lifted pipeline to slide down, and when the pipeline is pulled out of the soil, it will shake, etc., and it is easy to hit the operator and other technical problems
