Stabilizer for center line of vertical shaft

Abstract

The invention discloses a stabilizer for the center line of a vertical shaft. The stabilizer comprises a bucket, handles are installed on the left side face and the right side face of the bucket respectively, a resistance counteracting assembly is arranged in the bucket, and the resistance counteracting assembly is assembled to be used for counteracting wave power for shaking of the water surfacewhen water drips from the upper portion of the bucket. A limiting assembly used for limiting and protecting the resistance counteracting assembly is installed on the upper surface of the water bucket,a heavy hammer is arranged in the bucket, a fixing ring is installed on the upper surface of the heavy hammer, and a middle rope is fixed to the outer surface of the fixing ring. By arranging the resistance counteracting assembly, an outer connecting ring, a telescopic gauze element and an inner connecting ring are made of light plastic to form the resistance counteracting assembly, and then theresistance counteracting assembly can float on the water surface, so that fluctuation of the water surface in the bucket can be effectively stabilized, resistance of fluctuation of the water surface is effectively increased, and the fluctuation amplitude of the water surface is reduced; therefore, the shaking amplitude of the water surface is reduced, and the stability of the middle thread rope isensured without shaking easily.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a shaft centerline stabilizer. Background technique [0002] During the shaft excavation process, it is necessary to hang down the center line from the wellhead during model inspection to verify whether the well wall is over-excavated or under-excavated. Ensure the roundness of the wellbore. However, if the depth of the shaft is large, the length of the center line to the working face is too long, which will cause swings. The swing range is too large, which will affect the acceptance of the well wall. In order to reduce the swing range of the center line, the underground workers will fill the bucket with water. , submerge the centerline and the heavy cones that stretch the centerline into water, and rely on the resistance of the water to reduce the swing of the centerline. This can reduce the time for stabilizing the center line, thereby speeding up...

Problems solved by technology

However, if the depth of the shaft is large, the center line hangs too long to the working face, which will cause swings. The swing range is too large, which will affect the acceptance of the well wall. In order to reduce the swing range of the center line, underground workers will use buckets to fill them with water. , submerge the center line and the heavy cone that stretches the center line into the water, and rely on the resistance of the water to reduce the swing of the center line

This can reduce the time for stabilizing the center line, thereby speeding up the progress of the project and reducing the working time of personnel in the well, which is beneficial to safety. However, if the center line is submerged with water, if the well wall and the hanging pan are sprayed into the bucket, ripples will occur. , the water surface will shake, and it will also affect the stability of the center line. Therefore, it is necessary to solve the problem of water surface stability
