Aligning welding auxiliary tool for high-altitude large-diameter PP air pipe

Abstract

A butt welding auxiliary tool for a high-altitude large-diameter PP air pipe belongs to auxiliary facilities for building construction, comprises universal wheels, a stand column, a base, a steel plate, a hydraulic jack and a semi-arc pipe bracket, and is characterized in that the universal wheels are mounted below the base, the stand column is welded on the base, and the top of the stand column is welded with a large steel plate; the hydraulic jack is fixed on the large steel plate through a bolt; and the upper part of the small steel plate is connected with a semi-arc pipe bracket. The utility model solves the problems that the air pipe shakes violently, the air pipe butt joint is difficult and the joint welding quality is poorer due to the limitation of a screw rod hanging bracket when the PP air pipe mounting joint in the spherical grid structure is butted, and effectively improves the mounting quality and the construction efficiency of the air pipe.

Description

Technical Field

[0001] This utility model belongs to the field of ventilation and air conditioning technology. It is used in industrial plants for high-altitude butt welding and installation of large-diameter PP air ducts in spherical grid structures based on a lifting vehicle. Specifically, it relates to an auxiliary tool for high-altitude butt welding of large-diameter PP air ducts. Background Technology

[0002] Industrial plants producing clean energy generate large amounts of acidic and alkaline gases during production, which can seriously affect human health. These gases must be collected, treated, and discharged outside the plant promptly. PP ducts are lightweight, easy to install, and weldable. They have a long service life, reaching up to 50 years under specified operating conditions. These characteristics allow PP ducts to maintain stable performance in various industrial environments, meeting diverse and complex application requirements. With the rapid development of industrial plants, the use of large-span spherical space frame structures in plant construction is increasing, directly increasing the difficulty of duct system installation. When installing ducts within the space frame, it is necessary to avoid the members within the spherical space frame, significantly increasing the difficulty of traditional material loading methods and duct connection installation. Especially for PP ducts, which are plastic ducts connected by welding, the manual labor required by traditional construction methods increases exponentially. Furthermore, during duct alignment and welding within the space frame, the ducts are prone to swaying, further increasing the installation difficulty and posing significant safety hazards to the completed construction. Summary of the Invention

[0003] To address the aforementioned issues concerning PP duct installation, including duct loading and fixing, duct-to-duct connection, and welding quality in spherical grid structures, this invention provides an auxiliary tool for butt welding of large-diameter PP ducts at high altitudes.

[0004] The technical solution of this invention is: an auxiliary tool for butt welding of large-diameter PP ducts at high altitudes, including casters, a column, a base, a steel plate, a hydraulic jack, and a semi-circular pipe support. The feature is that casters are installed under the base, a column is welded to the base, and the top of the column is welded to a large steel plate; the hydraulic jack is fixed to the large steel plate by bolts; a small steel plate is welded to the hydraulic jack, and the upper part of the small steel plate is connected to the semi-circular pipe support.

[0005] This invention, by installing casters under the channel steel base, allows the PP duct to be finely adjusted in the forward, backward, left, and right directions when transported to the construction site, reducing the difficulty of operation at heights and minimizing safety hazards.

[0006] This utility model uses bolts to connect and fix the hydraulic jack to the steel plate at the top of the steel pipe. When the lifting vehicle transports the air duct to the construction position, the hydraulic jack can be used to make fine adjustments to the air duct up and down to ensure the flatness of the air duct joint.

[0007] This utility model uses a semi-circular tube support at the top to support the air duct at high altitudes, preventing the air duct from swinging back and forth during high-altitude operations and reducing the difficulty of assembling and welding the air duct at high altitudes.

[0011] Figure 1 , Figure 2 As shown, an auxiliary tool for butt welding of large-diameter PP ducts at high altitudes includes a base, four casters, steel pipes, steel plates, a hydraulic jack, and a semi-circular arc pipe support. The base is characterized by being welded from two channel steels 3, with first steel pipes 2 welded to each of the four corners of the base, and a caster 1 installed below each first steel pipe. A second steel pipe 4 is installed on the base, with its bottom welded to the base and its top welded to a large steel plate 5. Holes are drilled in the large steel plate 5 and the base of the hydraulic jack 7, and bolts 6 are used to fix the hydraulic jack 7 to the steel plate 5. A small steel plate 8 is welded to the hydraulic jack 7, and the upper part of the small steel plate 8 is welded to the semi-circular arc pipe support 9 to form a single unit.

[0012] Figure 1 , Figure 2 As shown, this device is placed on a lifting vehicle. During the alignment and welding of the air duct, the semi-circular tube support 9 supports the air duct. The omnidirectional wheels 1 at the bottom can be used to make fine adjustments to the air duct in the front, back, left, and right directions. The hydraulic jacks 7 can be used to make fine adjustments to the air duct in the up and down directions, which improves the installation quality of the air duct.
