Pipeline laying auxiliary device for water conservancy and hydropower engineering construction

Abstract

The invention discloses a pipeline laying auxiliary device for water conservancy and hydropower engineering construction. The pipeline laying auxiliary device for water conservancy and hydropower engineering construction comprises a base, a groove is transversely formed in the bottom of the base, the left side and the right side of the outer wall of a two-way lead screw are both sleeved with bearing seats in a threaded mode, fixing pieces are fixed to the tops of the bearing seats, and anti-counter-force supporting mechanisms are fixed to the sides, opposite to each other, of the two fixing pieces. Through arranging the anti-counter-force supporting mechanisms, a second driving device is driven to drive a connecting base to enable two supporting frames to move outwards, meanwhile, when the supporting frames move, two supporting plates drive rolling pieces to move upwards through wedge-shaped blocks, on one hand, the non-fixed part of a pipeline is supported, the force arm is increased, the fixed part of the pipeline is prevented from inclining upwards, and thus the fixed positions of the fixing pieces are prevented from being damaged due to stress; and on the other hand, the downward force of the pipeline does not directly act on the fixing pieces, so that the pipeline does not generate large indentations.

[0002] As we all know, during the pipeline laying construction process, due to the long length of the pipeline laying operation, the laying surface where the pipeline is laid cannot be guaranteed to be on a horizontal plane.

[0003] The pipeline laying auxiliary device for water conservancy and hydropower engineering construction is an auxiliary device used to support the pipeline to make it work better. The existing pipeline laying auxiliary device is to pass the two pipelines to be connected through two semicircular supports The seat fixes one end of the pipe, and then makes it aligned and connected, but because the pipe is long, the unfixed part of the outer wall of the pipe is downward at the semicircle support, and then exerts an upward reaction force on the part of the pipe located in the semicircle support, However, the existing two sets of semicircular support fixed pipelines generally use bolts or external driving devices to fix the semicircular support to the pipeline, so the reaction force exerted by the pipeline for a long time will easily cause damage to the bolt fixing place or cause the external driving device to be affected. Large reaction force damage affects the stability of the work and the cost of use
