Abstract
The invention provides an adjustable corrugated pipe installing and detaching method. An upper adjusting rod and a lower adjusting rod are connected between the lower tooth plate and the upper tooth plate through adjustable nuts; the three groups of adjustable corrugated pipe installing and detaching rods are mutually connected together through a chain. And (3) measuring the distance between the upper flange and the lower flange of the corrugated pipe to be installed, surrounding the corrugated pipe to be installed by 120 degrees by using an adjustable corrugated pipe installation and disassembly rod, compressing the corrugated pipe according to the measured distance, and placing the compressed corrugated pipe at the position to be installed. According to the invention, three groups of adjustable corrugated pipes are adopted for installing and detaching the linkage of the rod groups and the adjustment of the positive and negative threaded nuts, so that the corrugated pipes are prevented from being damaged due to uneven stress by adjusting the lengths of the corrugated pipes in the installation and detachment processes, and the rapid installation and detachment are achieved. Simple structure, convenient and fast. The method is suitable for being applied as an adjustable corrugated pipe installation and disassembly method.
Description
Technical Field
The invention relates to the installation and the disassembly of corrugated pipes with various specifications, in particular to the corrugated pipes which are suitable for high-temperature steam systems. In particular to an adjustable corrugated pipe installing and detaching method.
Background
The installation of bellows has long been a troublesome task, and the bellows leaving the factory has independent packaging. The corrugated pipe which is disassembled and independently packaged before installation can be stretched greatly under the action of tension, and when the corrugated pipe is installed, a part of length is required to be compressed to enter the gap position of the flange, in order to prevent the corrugated pipe from being damaged, the corrugated pipe is required to be compressed manually under equal force before installation, the compressed corrugated pipe is placed at the gap position of the flange, and bolts are penetrated after screw holes of the upper flange and the lower flange are aligned, so that the corrugated pipe can be slowly loosened, which is a great difficulty in installation; in addition, the corrugated pipes on the pipelines and the pipelines are disassembled, and as the corrugated pipes are not provided with the disassembling tools matched with the corrugated pipes, the corrugated pipes are easy to be damaged due to elastic deformation when being taken out from the gaps of the flanges under the action of elastic force in the disassembling process, and the reason is that the corrugated pipes are not used for slowly releasing the elastic force. The economic loss is not small no matter the damage caused by the installation or the disassembly, and the value is from thousands to tens of thousands, even more than hundreds of thousands.
Disclosure of Invention
In order to enable the length of the corrugated pipe to be adjusted in the process of installing and dismantling the corrugated pipe, the invention provides an adjustable corrugated pipe installing and dismantling method. According to the method, the technical problems of installation and disassembly of the corrugated pipes are solved through linkage of three adjustable corrugated pipe installation and disassembly rod groups and adjustment of the positive and negative threaded nuts.
The invention solves the technical problems by adopting the scheme that:
adjustable bellows installation and disassembly rod structure:
an upper adjusting rod and a lower adjusting rod are connected between the lower tooth plate and the upper tooth plate through adjustable nuts;
the three groups of adjustable corrugated pipe installing and detaching rods are mutually connected together through a chain.
The two ends of the adjustable nut are provided with a positive thread and a reverse thread.
The upper adjusting rod is provided with a reverse thread.
The lower adjusting rod is provided with a positive thread.
An adjustable corrugated pipe installing and detaching method comprises the following steps:
1. the distance between the upper flange and the lower flange of the corrugated pipe to be installed is measured, and the thickness of the upper gasket and the lower gasket is subtracted from the distance.
2. The corrugated pipes to be installed are surrounded by 120-degree pairs of adjustable corrugated pipe installation and disassembly rods, and the adjustable nuts are locked.
3. And compressing the corrugated pipe according to the measured distance, and simultaneously measuring and maintaining parallelism of the upper flange and the lower flange of the corrugated pipe in the compression process, wherein the length of the compressed corrugated pipe is smaller than the measured distance and the thickness of the two gaskets.
4. Placing the compressed corrugated pipe at a position to be installed, aligning flange eyes of the corrugated pipe with flange eyes of upper and lower flanges of a corrugated pipe pipeline to be installed, and installing bolts; slowly loosening the adjustable nut, and detaching the adjustable corrugated pipe mounting and dismounting rod group.
The invention has the advantages that as the three groups of adjustable corrugated pipes are adopted for assembling and disassembling the linkage of the rod groups and the adjustment of the positive and negative threaded nuts, the corrugated pipes can be quickly assembled and disassembled by adjusting the length of the corrugated pipes to avoid damage caused by uneven stress in the process of assembling and disassembling the corrugated pipes. Simple structure, convenient and fast. The method is suitable for being applied as an adjustable corrugated pipe installation and disassembly method.
