Description
Technical field
The present invention relates to heat enginnering technical field, the set of the more particularly to a kind of piping being used for without guide roller and housing
Assembling device and a kind of method being set with using the device to the piping without guide roller and housing.
Background technology
Low-pressure heater is the key equipment of the heat regenerative system of nuclear power station conventional island two.Its effect is will to be done in steam turbine
The steam of part work(is transported to heating feedwater in heater, to improve the temperature of water, reduces the steaming that steam turbine is discharged into condenser
Vapour amount, reduces energy loss, improves the cycle efficieny of therrmodynamic system.The European nuclear power low pressure in first outlet of domestic autonomy-oriented design
The proprietor of heater is group of Electricite De France (referred to as " EDF "), and the equipment is used for the serial nuclear power stations of EDF companies CP1, is France
Nuclear power implements the purchase order that first is invested China after the buying of nuclear power globalization strategy.It is also simultaneously China first according to Europe
Pressure vessel is instructed and the design of french pressure container standard entirely autonomousization and the nuclear power outlet device of manufacture.
The low-pressure heater (referred to as " EDF is low to be added ") is complicated, and (its piping is about 12.6mm to length length, and housing is about
11.2 meters), weight weight (its piping weigh about 30 tons, housing weigh about 8 tons), diameter is small (housing outer diameter only φ 1850mm), in housing
Portion's narrow space, belongs to leptosomatic equipment.The low shell adding bodies of EDF are without manhole, without guide roller between housing and piping, and housing
There was only 2mm with the theoretical gap in piping contact site, it is necessary to which ensureing that left and right stress is steady, in the case of balance, cunning is overcome completely
Kinetic force of friction, realizes the disposal package packing success of piping and housing.
The similar piping run into the past is that piping bottom sets guide roller and laying track with housing assembling method, is only needed
In piping both sides, chain block somewhat applies pulling force, will more easily realize that piping is set with housing.Due to existing skill
Art has the disadvantage poor universality, it is impossible to meet narrow gap, without guide roller, the slender type casing that diameter dimension is smaller, length is longer
Suit, for structure such as EDF it is low plus or more complicated product suit adaptability it is too poor, be that guide roller and laying are set first
Track, it is desirable to which interiors of products has enough spaces；Next to that the left-right balance during the suit of piping and housing is difficult to control,
It is not suitable for narrow gap piping and housing；Additionally due to piping rigidity is smaller, easily deformed in moving process.
The content of the invention
First technical problem to be solved by this invention there is provided a kind of suit mode that housing is sleeved on to piping
, realized during suit it is that shell position is precisely controlled, suitable for narrow gap be used for piping without guide roller with
The bushing device of housing.
Second technical problem to be solved by this invention is to provide a kind of once mild-natured using the light realization of bushing device
The method being surely set with.
To solve the technical scheme that first technical problem is used：A kind of piping being used for without guide roller and housing
Bushing device, including piping, housing and the support platform below piping, the support platform are supported on provided with some
Piping bottom and separate carrier unit, workbench is provided with the piping head end side, away from the piping
Workbench end be fixed with hoist engine, the housing is provided with housing is naturally outstanding above piping tail end side and housing
The moving crane hung, the horizontal center line of the housing is overlapped with the horizontal center line of piping, and the workbench is fixed with
Rope limiting device, the first pull rope that the rope outlet of the hoist engine is extended with, first pull rope is spacing through rope
Device and a point rope device is connected with the end of the first pull rope, the first joint phase of first pull rope and point rope device
Even, the second pull rope that the second joint of described point of rope device stretches out is respectively connecting to the both sides of housing, the spacing dress of the rope
The first pull rope put between point rope device is overlapped with the horizontal center line of piping, the level of second pull rope and piping
Center line is located at same level.
Further, the piping being connected with piping is respectively equipped with the both sides at the workbench end of the neighbouring piping tiltedly to prop up
Support.
Further, described point of rope device bottom is provided with rolls the roller being connected with workbench.
Further, the housing tail end is provided with the plumb line coplanar with the horizontal center line of piping.
To solve the technical scheme that second technical problem is used：A kind of piping being used for without guide roller and housing
The assembling method of bushing device, comprises the following steps：
A) support platform for being connected with the piping, is placed in horizontal field, the piping is horizontal, it is ensured that
The space for putting workbench is left in the piping head end side, is left in the piping tail end side for suspending housing in midair
Space；
B) workbench, is put in the piping head end side, housing is suspended in midair in the piping tail end side, and use institute
Piping bearing diagonal is stated to be connected between workbench and piping；
C), start the moving crane, the housing is moved to the tail end of piping, judge the plumb line and piping
Whether horizontal center line is coplanar；If coplanar, next step is carried out；If non-coplanar, the position of the housing is adjusted, makes institute
The horizontal center line for stating plumb line and piping is coplanar, then carries out next step；
D), start the hoist engine, draw the housing and be set with to piping, when the housing bottom is close to support list
When first, the hoist engine is stopped and removes close carrier unit；
E) above step d), is repeated, until completing the complete suit of the piping and housing.
Beneficial effect：Start hoist engine, under the draw of the first pull rope and the second pull rope, the housing edge of suspention
The horizontal center line movement of piping, under the position-limiting action of rope limiting device, it is ensured that housing is all the time along along the level of piping
Heart line is moved, and realizes and shell position is precisely controlled；Because the rigidity of piping is smaller, it is sleeved on using by housing on piping
Mode, effectively reduce the deformation of piping.When housing bottom is close to carrier unit, hoist engine is stopped, and removes close
Carrier unit, until completing the complete suit of piping and housing.Housing and pipe during suit has been effectively ensured in this method
The accurate cooperation of system, and suit process is easily controllable, easily realizes disposable steady suit.
