Abstract

The utility model discloses a convenient-to-disassemble multifunctional portal frame for mounting a large-aperture pipeline. The convenient-to-disassemble multifunctional portal frame comprises two upright posts, a beam, skew girders, lifting lugs, steel ladders, bases, flanges, protective steel plates and positioning regulators, wherein each upright post consists of an upper upright post and a lower upright post, which are connected through a flange; each skew girder consists of an upper skew girder and a lower skew girder, which are connected through a flange; the tops of the upper upright posts are welded to the two ends of the beam respectively; the tops of the upper skew girders are welded to the middle part of the beam; the lower ends of the skew girders are welded to the upper parts of the lower upright posts; the lower ends of the lower upright posts are welded to the bases; the protective steel plates and the steel ladders are welded to the lower upright posts; the lifting lugs are arranged on the beam; and the positioning regulators are distributed on the protective steel plates opposite to pipe middles of large-aperture steel pipes. The portal frame can be conveniently mounted and disassembled; due to the arrangement of the protective steel plates and the positioning regulators, constructors can be effectively prevented from being injured by collapses; the steel pipes can be accurately fixed at set positions, so that construction quality can be ensured; and the convenient-to-disassemble multifunctional portal frame is suitable to be used for a construction organization for mounting the large-aperture pipeline.

Description

The multi-functional portal frame of portable type of heavy-caliber pipeline is installed

Technical field

The utility model relates to a kind of portal frame, particularly a kind of for convenient install heavy-caliber pipeline carry out on-the-spot group to welding wait construction need portal frame, belong to the construction equipment in plumbing field.

Background technique

For heavy-caliber pipeline is carried out scene group to and welding, generally all need be in the large-diameter steel pipe both sides the on-the-spot portal frame of installing.But existing portal frame structure is too simple, mainly is welded into a glyph framework by column and crossbeam, and structure is too simple, and dismounting needs welding, and no safety prevention measure takes place to injure because of the landslide personnel that cause easily.

Summary of the invention

The purpose of the utility model is in order to overcome the deficiency of above-mentioned existing portal frame, to design a kind of reasonable in design, the multi-functional portal frame of portable type of the installation heavy-caliber pipeline that easy installation and removal and Safety performance are good.

The multi-functional portal frame of portable type of the installation heavy-caliber pipeline of the utility model; Its structure comprises 2 root posts, crossbeam, Dou beam, hanger, steel ladder and base, also comprises flange, shoulder guard and positioning regulator, and said column is formed by connecting through flange upper pillar stand and lower pillar stand; The Dou beam is formed by connecting in last Dou beam and following Dou Liang Jingfa orchid; The upper pillar stand top is welded on the crossbeam two ends respectively, and last Dou back end is welded on the crossbeam middle part, welding lower pillar stand top, following Dou beam lower end; The lower pillar stand lower end is welded on the base; Shoulder guard and steel ladder are welded on the lower pillar stand, and hanger is contained on the crossbeam, and positioning regulator is distributed on the shoulder guard with large-diameter steel pipe pipe tripe corresponding position.

In order further to improve the mechanical strength of lower pillar stand, can set up stiffening rib and Dou stay tube, stiffening rib is distributed on the shoulder guard, and the Dou stay tube is welded between base two ends and the lower pillar stand top.

Said positioning regulator comprises outer tube, interior pipe and latch, is distributed with hinge last respectively on said outer tube and the interior pipe, and outer tube back-end is welded on the shoulder guard, and interior pipe is inserted in the outer tube, and pipe is inserted in the hinge last with latch behind the position of outer tube and locatees in regulating.

The multi-functional portal frame of portable type of the installation heavy-caliber pipeline of the utility model is connected through flange with lower pillar stand owing to change column into upper pillar stand, and the Dou beam changes the Dou beam into and is connected with following Dou Liang Jingfa is blue, can carry out installation and removal very easily to portal frame; Because of shoulder guard is housed, can effectively protect the workmen to avoid the landslide injury again; Also, help guaranteeing construction quality because positioning regulator can accurately be fixed on large-diameter steel pipe on the desired location.Be adapted at installing unit in charge of construction's use of heavy-caliber pipeline.
