Description
Technical field
The invention belongs to metallurgical plant area's Environmental-protecting dust-removing overhaul of the equipments technical field, and in particular to a kind of vertical ripple in high-altitude is mended
Repay the replacing options of device.
Background technology
FlexbleJoint is visual plant, the facility as metallurgical plant area's Environmental-protecting dust-removing, the maintenance of FlexbleJoint at present,
The problem of the following aspects be present in replacing：Firstth, it is big in high-altitude, hoisting difficulty.Due to vertical FlexbleJoint and pipeline
Installation present position height it is high, cause high-altitude to change condition difficult, can not directly be changed and arrived using the direct handling of hoist tool
Very big difficulty be present in position, lifting, dismounting, installation process.Secondth, without inspection platform.Changing in work progress needs operation people
Member is cut and is welded to connect pipeline using gas welding unit, and personnel need to arrive fixed position and carry out operation, and without inspection platform, operation is not
Convenient, operating personnel can not be guaranteed safely.3rd, more crane coordinating operations are needed, enough liftings are needed for this
Face place and raising space.
The content of the invention
The invention aims to solve technical problem present in prior art, there is provided a kind of easy to operate, simple
Replacing options that are easy, safe and reliable, changing the vertical FlexbleJoint in high-altitude that difficulty is low and labor intensity is small.
In order to achieve the above object, the present invention uses following technical scheme：A kind of replacing of the vertical FlexbleJoint in high-altitude
Method, this method comprise the following steps：
A, crane is arranged on the vacant lot of the vertical FlexbleJoint both sides in high-altitude, a crane, which is hung, is connected to the vertical ripple in high-altitude
The lower section connecting pipe of line compensator lower end, another crane for hoisting are loaded with the cage of operating personnel and make cage close to lower section
Connecting pipe, operating personnel cut the pipeline short section that one section of length is 450-550mm from below on connecting pipe, and pipeline is short
Section is extracted out；
B, the hanger at the top of the vertical FlexbleJoint in high-altitude is hung using a crane, another crane for hoisting is loaded with operation
The cage of personnel simultaneously makes cage close to the top connecting pipe for being connected to the vertical FlexbleJoint top in high-altitude, operating personnel's cutting
The junction of top connecting pipe and the vertical FlexbleJoint in high-altitude causes the vertical FlexbleJoint in high-altitude and top connecting pipe
Separation, after the vertical FlexbleJoint whereabouts 200-300mm in high-altitude, two cranes coordinate the vertical FlexbleJoint in high-altitude from installation
Removed on position and the vertical FlexbleJoint in high-altitude is hoisted to ground；
C, fabrication and installation are circular on the new vertical FlexbleJoint in high-altitude while the vertical FlexbleJoint in waste and old high-altitude is removed
Platform, circular platform using a crane cause new high-altitude after completing to the new vertical FlexbleJoint handling in high-altitude
Vertical FlexbleJoint top is docked with top connecting pipe, and another crane for hoisting is loaded with the cage of operating personnel so that hanging
Cage is close to the vertical FlexbleJoint top in high-altitude and top connecting pipe joint, and operating personnel is to the vertical ripple in high-altitude to connecting
Tentatively welded with top connecting pipe seam on line compensator top；
D, after the vertical FlexbleJoint in high-altitude is tentatively welded and fixed, circle of the operating personnel station on the vertical FlexbleJoint in high-altitude
Abutment joint is further welded on shape platform, and after the completion of upper weld, the pipeline short section of extraction is returned to lower section connecting pipe
Simultaneously solder joint is filled, completes the replacing of the vertical FlexbleJoint in high-altitude.
Further, the circular platform in the step C includes being fixed on vertically outside the vertical FlexbleJoint in high-altitude
Multiple columns, toroidal frame is fixed with the column, circular guard rail is provided with the external margin of the toroidal frame.
Further, cut when pipeline short section is cut in the step A using gas welding.
Further, the crane is truck crane.
The present invention has the advantages that compared with the prior art：The present invention is first under the vertical FlexbleJoint in high-altitude
One section of pipeline short section is cut on square connecting pipe so that the vertical FlexbleJoint in high-altitude is removed when lifting is fallen and leaves space, so
The junction of cutting top connecting pipe and the vertical FlexbleJoint in high-altitude causes the vertical FlexbleJoint in high-altitude to connect with top afterwards
Adapter road separates, and makes peace while removing the vertical FlexbleJoint in waste and old high-altitude outside the new vertical FlexbleJoint in high-altitude
Fill circular platform, then the new vertical FlexbleJoint handling in high-altitude is reached the standard grade, and by the new vertical FlexbleJoint in high-altitude with
Top connecting pipe welding, finally pipeline short section backfill and weld the replacing mesh that can be achieved with the vertical FlexbleJoint in high-altitude
's.The present invention is cooperated and its set installation circular platform by crane, solves the height in high-altitude, without inspection platform
The problem that empty vertical FlexbleJoint is changed, shortens maintenance duration, improves overhaul efficiency, significantly reduce maintenance worker's
Labor intensity, the safety of maintenance worker in effective guarantee maintenance process, it is a kind of to change efficient and convenient, safe, Yi Shi
The existing, replacing options of the vertical FlexbleJoint in practical high-altitude, can also promote the use of the production of other similar industrial pipelines,
In overhauling project work progress, there is good application prospect and promotional value.
