Adjustable supporting device for lower pipeline

Abstract

The invention discloses an adjustable supporting device for a lower pipeline, and relates to the technical field of pipelines. The adjustable supporting device comprises a supporting plate; L-shaped plates which are oppositely arranged are symmetrically installed on the upper surface of the supporting plate; a screw rod is rotationally connected between top plates of the L-shaped plates and the upper surface of the supporting plate; the screw rod is correspondingly matched with a first nut, a second nut and chain wheels from top to bottom; and a guide cylinder is fixedly installed on the sideface of the second nut, and a horizontal roller is arranged on the two guide cylinders in a sliding fit mode. A rotating shaft is rotated to enable a first worm to be in engaged transmission with a first turbine and enable a gear to be in engaged transmission with a rack, and left-right adjustment of the horizontal roller is achieved; and a transmission shaft is rotated to enable a second worm wheel and a second worm to be in meshing transmission and the two chain wheels to be in transmission, so that the first nut and the second nut drive a telescopic inclined roller and the horizontal rollerto ascend. In the process, spiral pipes can be adjusted left and right and up and down, the concentricity correction convenience of the two spiral pipes is improved, the welding quality for people isimproved, and the road laying process is accelerated.

Description

technical field [0001] The invention belongs to the technical field of pipelines, in particular to an adjustable supporting device for lowering pipelines. Background technique [0002] With the needs of people's transportation and traffic, more and more roads are paved; when laying roads, sewer pipes usually need to be buried; people need to weld the spiral pipe to form a sealed inner pipe of the sewer pipe, and the surface of the inner pipe Wrap the buffer and finally set the outer pipe on the outside to build the sewer pipe; [0003] And when people weld two spiral pipes, people often adopt other beddings (such as bricks, wood blocks, etc.) to support the spiral pipes to facilitate people's welding, but the bedding cannot be adjusted, which will cause people to carry out two spiral pipes. When welding with concentricity correction, there are large errors and welding quality problems; and when people correct the concentricity of the spiral pipe, it will increase people's l...

[0003] And when people weld two spiral pipes, people often adopt other beddings (such as bricks, wood blocks, etc.) to support the spiral pipes to facilitate people's welding, but the bedding cannot be adjusted, which will cause people to carry out two spiral pipes. When welding with concentricity correction, there are large errors and welding quality problems; and when people correct the concentricity of the spiral pipe, it will increase people's labor pressure and slow down the efficiency of the entire sewer pipeline laying; therefore, there is an urgent need for a method for Adjustable support device for the lower pipe to provide support and adjustment functions for the spiral pipe
