Description
Technical field
The present invention relates to pipeline and pressure vessel manufacturing field more particularly to a kind of tower type container conical skirt cylinders
Welding manufacture.
Background technology
Tower type container is the vertical vessel that a kind of length is larger in petrochemical industry container.Conical skirt cylinder is widely used in internal diameter
Small, height is high, and in the big tower type container of wind load, foundation bolt is increased by its increased advantage of cone big opening end diameter
The receiving area of quantity and grade slab, half cone-apex angle of the upper conical skirt cylinder of standard is no more than 15 °.
Conical skirt cylinder is spliced according to length by more piece cone, due to being difficult to turn round along axis, can not be used certainly
Dynamic welder conical shell butt weld, can only by the vertical docking of conical shell shell ring, shell ring docking location apart from ground compared with
Gao Shi, welding operation is very difficult and there is certain danger, and needs to carry out back chipping in inside butt welding road after outside weldings,
The welding of medial and lateral is carried out again.
After the completion of conical shell manufacture, need to be connected with container, pipeline on container need to stretch out inside skirt with
External pipe connects, and needs on skirt trepanning and installs take over 6, the setting angle of pipeline and cone and its arrive container axis
Distance be difficult to measure, pipeline can be more and positioned at multi-faceted according to design requirement.
Overturning is carried out to conical shell by overhead traveling crane at present and measures work, if but overhead traveling crane is used for a long time, there are all
More difficult and unfavorable factors, such as：1. be easy to cause cone be loaded position deformation；2. there is the risk for the cone outer wall part that collides with；
It is taken over 3. can not accurately install；4. the frequent operation of overhead traveling crane is needed, it is time-consuming and laborious.
For these reasons, the present inventor deeply grinds existing tower type container conical skirt and rolling system
Study carefully, conical shell can be stably placed on turning rolls to design one kind, the level that can be manufactured as straight barrel
Slewing equipment.

7；
Step 4, conical shell 5 is lifted by crane, is overturn to level, bracing ring 1 is dropped to and horizontal two turning rolls 8 put is flat
Steady contact.
Wherein, in step 2, the assembling of circle 1 and free bearing 2 is supported in platform, concrete operations are as follows：First in taper
Select suitable installation site at two on cylinder 5, cylinder center of gravity both sides of the status requirement in present apparatus adjustable range, and not
Interfere with shell ring docking location and other parts installation site, meeting can be according to the practical feelings of conical shell 5 after conditions above
Condition is rationally adjusted.The outer diameter corresponding to position at two is measured, adjusts the free bearing 2 at large and small end respectively by measuring size
Hole site is adjusted with bracing ring 1, the band of position is measured size to meet.1 make-up of bracing ring for installing free bearing 2 is connected.Peace
It should be noted that lower free bearing inclined direction is consistent with 2 taper direction of conical shell when filling free bearing 2.
In step 3, by bracing ring 1, lifting lug 1-3 levels lift by crane bracing ring 1 everywhere, and concrete operations are as follows：It installs first
Big mouth circle bracing ring 1, enters from the conical shell osculum end cap of setting, steady to decline until lower free bearing 2-6 is complete with conical shell 5
Fitting, on the cylinder of lower free bearing 2-6 tops corresponding position weld locating piece 7, locating piece 7 require be bonded with lower free bearing after again with
Cone is welded, and is removed before the present apparatus is removed.Secondly installation osculum bracing ring 1 and locating piece 7；
Wherein, locating piece 7 is provisional attachment, and free bearing and cylinder are welded on after horizontal rotation device and conical shell installation
On the cylinder at body contact position osculum end, and it is bonded with free bearing.After being assembled due to horizontal rotation device and conical shell 5, both by
The radial load brought to cylinder dead weight to the present apparatus, also by the axial force brought along cone surface towards osculum extreme direction, is being rolled
On wheel carrier 8 revolution for a long time can occur there are conical shell 5 axial float and with the risk of the disengaging of the present apparatus, therefore need by fixed
Position block 7 fixes the present apparatus and conical shell 5, and removed from conical shell 5 when the present apparatus is using dismounting.In step 4,
Distance between two groups of devices is measured, is well placed two turning rolls 8 in level ground by size, lifts by crane conical shell 5, steady overturning is extremely
Level drops to bracing ring 1 and is steadily contacted with turning rolls 8, realizes revolution operation of the conical shell on turning rolls 8.
A preferred embodiment according to the present invention, as shown in Figure 1,3, the conical shell 5 after installation can be steady
Ground is placed on turning rolls 8, and the axis of conical shell 5 is parallel with level ground.Cone axis is measured on the basis of level ground
To the distance of level ground, distance and angle of the take over 6 apart from cone axis can will take over position by turning round turning rolls 8
Be raised to extreme higher position, with horizon rule adjustment take over cylinder angle and measure 6 end of take over to level ground distance,
6 end face of take over is calculated to the distance of conical shell axis, and is adjusted and is fixed and welds to satisfactory height.
The present invention is described in detail above in association with specific embodiment and exemplary example, but these explanations are simultaneously
It is not considered as limiting the invention.It will be appreciated by those skilled in the art that without departing from the spirit and scope of the invention,
