Direct-buried pipe sleeving process production line

Abstract

The invention discloses a direct-buried pipe sleeving process production line. The direct-buried pipe sleeving process production line comprises a conveying vehicle, a loading lifting appliance and aworkbench; the conveying vehicle comprises a trolley, running wheels, a running driving mechanism, a hydraulic station, a rotary supporting base, a rotating disc, a V-shaped bracket and a hydraulic cylinder; the running wheels are arranged on the trolley; the running driving mechanism drives the running wheels to rotate to drive the trolley to run; the rotary supporting base is fixedly mounted onthe upper side of the trolley; the rotating disc is rotationally connected with the rotary supporting base; and a bottom plate is fixedly mounted on the rotating disc. The direct-buried pipe sleevingprocess production line has the beneficial effects that a whole set of special direct-buried pipe sleeving process production line is provided; special equipment is provided for conveying, hoisting, pre-treatment and sleeving of a steel pipe; the operation is convenient and fast; the sleeving production efficiency is enhanced; and as a rotating support is arranged under the V-shaped bracket, eventhough the running speeds of the two trolleys has a difference, a direct-buried pipe cannot fall off from the trolleys so that the direct-buried pipe sleeving process production line is safer and morereliable.

Description

technical field [0001] The invention belongs to the technical field of direct-buried processing equipment, and in particular relates to a direct-buried pipe assembly process production line. Background technique [0002] The direct buried pipe is composed of an inner pipe and an outer pipe. The inner pipe is a steel pipe for conveying medium, the outer pipe is a high-density polyethylene outer pipe, and the insulation layer between the inner pipe and the outer pipe is made of rigid polyurethane foam. Directly buried pipes have the advantages of effective heat preservation, waterproof and anti-corrosion, flame retardant, cold resistance, high strength, etc., and are widely used in heating, oil transportation and gas transportation. In the production process of the direct buried pipe, the outer pipe needs to be installed on the inner pipe. Before the installation, the inner pipe needs to be pretreated and the bracket installed. Special spreaders and mobile trucks are required...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems in the prior art that there is no special production equipment for the direct-buried pipe assembly process, the handling and hoisting of the direct-buried pipe is troublesome, and the inner pipe advance resistance is large during the assembly process, which makes the production efficiency of the assembly process low. A direct buried pipe set process production line
