Abstract
The invention discloses a package packing method of a liquefied natural gas tanker container. An inner tank is set up on the two ends of assembling process pipes through special supports, the lower section of each support is provided with four concave wheels which are engaged with outer cylinder guide rails, two support pipes which are engaged with the assembling process pipes on the two ends of the inner tank are arranged on the upper end of the support, the support is arranged on the outer cylinder guide rails whose heights are decided by the center shaft of the inner tank overlapping the center shaft of the outer cylinder. The inner tank and the support are pushed by a truss hoist and other devices on the far end from the inner tank to the outer cylinder, and the inner tank is slowly sleeved in the outer cylinder to the assembling position. The center of the inner tank can be more accurately located as the invention adopts double supports, and the axiality of the inner tank and theouter cylinder is high, the invention is specially used to pack assembly under the condition that the distance between the outer surface of the inner tank and the inner surface of an outer cylinder issmaller. The double support enables the inward swallowing process of the inner tank much smoother, which avoids that the inner tank inclines to hit the outer cylinder and result in damaging to an insulation layer in the packing process, and largely reduces the packing operation time, and the safety is much higher.
Description
Technical field:
The present invention relates to a kind of inside and outside tank body assembling of machine building industry bimetal wall cryogenic liquid storage tank, particularly a kind of liquefied natural gas tanker container nesting method of being used for.
Background technique:
At present, LNG storage tank manufacturer does not have unified suit technology, all is that the technical specifications of each producer's basis oneself design the suit scheme voluntarily, generally takes an end to utilize stent support, and the other end is sling, along the assembling method of guide rail propelling.Along with the development of technology, require storage tank externally under the situation of size constancy the efficient loading capacity increase as far as possible, therefore inside and outside tank body spacing then diminishes thereupon, construction brings higher technical requirements to suit like this.In the actual production, because suit scheme imperfection often causes the suit engineering time longer, or the heat insulation layer of tank body destroys in making.Long as interior tank body heat insulation layer exposure time in atmosphere, cause the later stage difficulty of finding time, influence thermal insulation property; Or suit technology is unreasonable, the tank body heat insulation layer damage that bumps in making; Or the suit Location accuracy is not enough, makes inner support that difficulty is installed.
Summary of the invention:
The object of the present invention is to provide a kind of liquefied natural gas tanker container nesting method.For machine building industry bimetal wall cryogenic liquid storage tank manufacture process provides inside and outside tank body suit method of construction of a cover and device, reach quick, safe suit construction, accelerating construction progress ensures workmanship.
The present invention seeks to realize like this,
(1) welding of interior tank body is finished, the heat insulation layer wrapping finishes and through being up to the standards, outer tank body direct tube section welding is finished, outer tank body direct tube section is inboard to become the left and right sides, 30 ° of angles with outer tank body direct tube section central vertical line, vertically weld two internal guide rails with outer tank body direct tube section central axes, internal guide rail tank body direct tube section one end outside extends to outer at least one the interior length of tank of outer tank body direct tube section, and reliable supporting is arranged;
(2) interior tank body is erected at the assembly technology pipe place at two ends by front end supporting frame and rear end supporting frame, four concave surface wheels that cooperate with the outer cylinder body guide rail respectively are equipped with in front end supporting frame and supporting frame lower end, rear end, the upper end is to cooperate support tube with interior tank body two ends assembly technology pipe, front end supporting frame and rear end supporting frame are placed on the outer rail, and height is so that the central shaft of interior tank body overlaps with outer tank body direct tube section central shaft is as the criterion;
(3) be hung in far-end promotion interior tank body, front end supporting frame and the rear end supporting frame of interior tank body with the purlin, slowly interior tank body be inserted in the outer tank body direct tube section to rigging position apart from outer tank body direct tube section.
The present invention is owing to adopted double bracket to make interior tank body centralized positioning more accurate, and interior tank body and outer tank body direct tube section coaxality height are particularly useful for the suit assembling under interior tank body outer surface and the less situation of outer tank body direct tube section internal surface spacing; Tank body gulped down that into process is more steady in double bracket made, avoided in the cover process of assembling in tank body generation deflection and collide the destruction that outer tank body direct tube section causes heat insulation layer, the suit operating time can shorten greatly, Security is higher.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
Embodiment:
The present invention is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention is made of outer tank body direct tube section 1, interior tank body 2, assembly technology pipe 3, rear end supporting frame 4, concave surface wheel 5, guide rail support 6, outer rail 7, front end supporting frame 8, internal guide rail 9, outer tank body direct tube section 1 inboard becomes the left and right sides, 30 ° of angles with outer tank body direct tube section 1 central vertical line, vertically weld two internal guide rails 9 with outer tank body direct tube section 1 central axes, internal guide rail 9 tank body direct tube section 1 one ends outside extends to outer outer rail 7 at least one interior tank body 2 length, and outer rail 7 has reliable guide rail support 6.Interior tank body 2 is erected at assembly technology pipe 3 places at interior tank body 2 two ends by front end supporting frame 8 and rear end supporting frame 4, front end supporting frame 8 is equipped with four concave surface wheels 5 that cooperate with outer rail 7 and internal guide rail 9 with rear end supporting frame 4 lower ends, front end supporting frame 8 at first is placed on the outer rail 7 with rear end supporting frame 4, and height is so that the central shaft of interior tank body 2 overlaps with the central shaft of outer tank body direct tube section 1 is as the criterion.Tank body 2 and front end supporting frame 8 and rear end supporting frame 4 in tank body 2 promotes apart from the far-end of outer tank body direct tube section 1 in being hung in the purlin, slowly that interior tank body 2 tank body direct tube section 1 outside outer rail 7 and internal guide rail 9 are inserted in is interior to rigging position.
Claims (1)
