When in use, whole installation process needs by electric block and hoistable platform, all assemblings above-mentioned assemble method
Connection work is required for carrying out operation in high-altitude, it is necessary to hoistable platform is back and forth lifted, and difficulty of construction is big, risk is big, to liter
Drop platform is higher by degree, and whole scene installment work is less efficient.
The content of the invention
The present invention provides a kind of installation method of in-site installation suspension type valve tower, to solve to be suspended in midair present in prior art
The in-site installation of formula valve tower is mainly causes in-site installation danger technical problem high, less efficient in work high above the ground.
The technical scheme of the installation method of in-site installation suspension type valve tower provided by the present invention is：A kind of in-site installation hangs
The installation method of hanging valve tower, first, the top layer valve group of lift valve tower has been suspended in midair to setting height using jack up unit, and the setting is high
Spend to be available for the staff on field ground that first lower floor's valve group close to top layer valve group of valve tower is arranged on into top layer valve group
The height of lower section, then steps up top layer valve group and during stepping up by the work on field ground by jack up unit
Personnel's being sequentially connected in series below first lower floor's valve group from top to bottom by remaining each lower floor's valve group successively, finally, is filled by raising
Put and continue to lift up top layer valve group and extremely the suspention that top layer valve group and top are connected on the top girder steel built at the scene can be connected knot
The connected height in the lower end of structure, and top layer valve group is connected with the lower end of the suspention attachment structure.
Before using top layer valve group to the setting height described in jack up unit suspention raising, by the suspention connection knot
The top of structure is connected on the top girder steel built at the scene.
Described suspention attachment structure is suspension insulator.
First described lower floor's valve group by suspend in midair with the suspention attachment structure identical draw bail be serially connected in it is described
Top layer valve group lower section, described remaining each lower floor's valve group is passed sequentially through suspends in midair with the suspention attachment structure identical draw bail
It is serially connected in corresponding lower floor's valve group lower section.
Described jack up unit is many electric blocks of synchronization action of fixed building top at the scene.
Described top layer valve group includes top frame and the valve layer top apparatus in top frame, and jack up unit leads to
Cross suspention raising top frame to the setting height and during raising by the staff on field ground by valve layer top
Portion's equipment is arranged in top frame and top layer valve group is risen into setting height with described in realization.
The beneficial effects of the invention are as follows：In the installation method of in-site installation suspension type valve tower provided by the present invention, first
The top layer valve group of valve tower is suspended in midair using jack up unit has risen to setting height to cause that the staff on field ground can be by
First lower floor's valve group is arranged on top layer valve group lower section, then by remaining each lower floor's valve group during top layer valve group is stepped up
Be sequentially connected in series below first lower floor's valve group, finally again by top layer valve group be connected on the top girder steel built at the scene in advance
The lower end for suspending attachment structure in midair is connected, and is finally completed the in-site installation of suspension type valve group, in-site installation side provided by the present invention
In method, stepped up during top layer valve group moves up in uprisal device, by the staff on field ground by each
Lower floor's valve group lower section for being connected in top layer valve group successively, with the scene for carrying out work high above the ground by hoistable platform in the prior art
Installation method is compared, and not only installation effectiveness is high, is also effectively reduced the work high above the ground time of staff, is effectively reduced to lifting
The degree of dependence of platform, reduces work high above the ground danger, reduces difficulty of construction and construction risk, while, it is not necessary to staff has
Standby work high above the ground experience, reduces the requirement to staff.
Further, jack up unit is many electric blocks of synchronization action of fixed building top at the scene, using same
The electric block of step action, can not only lift Hoisting Security coefficient, can also lift site operation efficiency, reduce construction cost.
Further, jack up unit is by suspending raising top frame in midair to the setting height and during raising by existing
Be arranged on valve layer top apparatus in top frame and rise to top layer valve group with described in realization by the staff on Ground
Setting height, during top layer valve group is assembled, has been realized rising to the setting height, and top layer valve group is assembled not in addition
Individually arrangement installation time, improves operating efficiency.
