Summary of the invention
The present invention is intended to the problems referred to above solving the pipe installation method existence of existing high-altitude, and provide a kind of day vehicle overhauling electric hoist mounting point that utilizes higher than the mobility feature of overhead traveling crane, using overhead traveling crane as a transition vector, in handling safety reliably and under greatly cost-saving prerequisite, complete the either inside high-altitude pipeline mounting construction method of Pipe installing.
The technological scheme that the present invention solves the employing of its technical problem is:
A kind of either inside high-altitude pipeline mounting construction method, carry out in the steps below:
(1) on overhead traveling crane running trolley, set up frock: described frock comprises two supports be fixed on overhead traveling crane running trolley machine supporting beams, described two supports be fixed with respectively the bracket of support pipeline and be used for lifting the pole of pipeline;
(2) surface duct is prefabricated: according to Pipe installing size, carries out retaining wall on slope and rust cleaning, painting process construction on ground;
(3) lifting pipeline is put in above frock: utilize vehicle overhauling electric hoist in sky in factory building to carry out lifting pipeline, hoisting height exceedes a day height; Run below overhead traveling crane to sky vehicle overhauling electric hoist; Running trolley, is put in pipeline above frock, suitably fixes;
(4) utilize frock that Pipe installing is in place: to run overhead traveling crane, pipeline is transported to mounting point; The lifting chain block that on frock pole, bolt is hung is utilized to be sling by pipeline; Running trolley, transports to the pipeline sling above Pipe installing position, then pipeline is dropped on installation in position on pipe support.
Further, described frock by be positioned at overhead traveling crane running trolley machine supporting beams two ends and with machine supporting beams be welded and fixed two portal trestles, the saddle bracket matched with mounted pipe diameter be weldingly fixed on described portal trestle, be weldingly fixed on described portal trestle and add the pole that oblique pull is used for lifting pipeline and form, two portal trestle upper surface level heights are higher than device height on dolly, and pole top bolt hangs with lifting chain block.
Compared with prior art, adopt the present invention of technique scheme, make use of a day vehicle overhauling electric hoist installation position and set high the feature with overhead traveling crane mobility, using overhead traveling crane as a transition vector, in handling safety reliably and under greatly cost-saving prerequisite, complete the installation of pipeline, its invention effect is:
Pipe installation process does not limit by any ground field condition, and personnel's operation, on crown platform, improves the Security of personnel's work surface; Utilize factory building existing resource to construct, decrease construction plant lifting cost use, reduce construction cost, shorten the construction period, improve efficiency of construction; Frock making is simple, and material can utilize on-the-spot residue waste-material-preparing, cost-saving.
