Description
Technical field
The present invention relates to transportation technology, more particularly to a kind of longspan structure piece for land liquefied natural gas module
Transportation technology.Belong to Offshore Engineering field.
Background technology
Large-scale liquefied natural gas modularization processing factory in building course, because center piping lane modular structure form is similar,
One layer of deck plate quite, in order to realize that integrated cleaning is built, generally, is divided into several knots by weight according to the span of its axis
Tile is built.Consequently, it is possible to structure piece is more, general assembly workload is bigger, and the duration will extend, therefore, built in module
Cheng Zhong, should try one's best increases the workload of shop-fabricated, to reduce the workload during general assembly.But, thus generate again new
Problem, because structure burst has more hinged joint, and burst span is excessive, and the weight and flexibility of burst also can significantly increase
Plus, therefore, burst is susceptible to bending deformation, especially in transportation.And existing transport vehicle is not enough to bearing structure
Burst, even if by two 370 tons of flat car integrations of operation, solving the problems, such as Lack of support, but, in transportation,
Due to the nonsynchronous problem of two chassis, in cornering operation, it is susceptible to structure piece and topples, there is larger potential safety hazard.
The content of the invention
It is a primary object of the present invention to the disadvantages mentioned above for overcoming prior art to exist, and provide a kind of longspan structure piece
Transportation technology, it can not only be realized to being hinged more, the transport of the structure piece of large span, solve existing place haulage vehicle
The hauling operation problem of longspan structure piece cannot be realized；And, in transportation, segment axis are replaced by transportation frame
Means of transportation, greatly reduce the input amount of axis, saved dolly axis resource, and then save ultromotivity hydraulic flat
The lease expenses of car；Additionally, also achieving safe and efficient hauling operation, the logistic efficiency for the treatment of of the earth piece transport is improve,
While cost of transportation is reduced, the construction period is substantially reduced.
The purpose of the present invention is realized by following technical scheme：
1st, a kind of transportation technology of longspan structure piece, it is characterised in that：Using following steps：
The first step：Large scale structure piece is carried out in prefabricated workshop prefabricated；
Second step：Arrange that several hydraulic jacking devices carry out jacking work at the Jacking point specified below large scale structure piece
Industry；
3rd step：After hydraulic jacking device is by large scale structure piece jacking to specified altitude assignment, below large scale structure piece
Temporary support is installed, is used to be supported fixation to large scale structure piece, then, withdraw hydraulic jacking device；
4th step：The perfect ultromotivity hydraulic flat car of configuration, it is then determined that the dolly headstock of ultromotivity hydraulic flat car
Position, dolly axis quantity, and transportation frame is connected with the dolly axis of ultromotivity hydraulic flat car；
5th step：In prefabricated workshop into, array ultromotivity hydraulic flat car is sailed the lower section of large scale structure piece, will be large-scale
Workshop to advance fitting-out place is transported out after structure piece jack-up；
6th step：Ultromotivity hydraulic flat car is withdrawn, is continuing with temporary support and is supported, and in advance fitting-out
Ground, completes the advanced outfitting work of the structure loose mail on large scale structure piece；
7th step：The lower section of the large scale structure piece where sailing ultromotivity hydraulic flat car into advance fitting-out place, and pass through
Transport sails out of advance fitting-out place to spraying car after the hydraulic power unit jack-up large scale structure piece of ultromotivity hydraulic flat car itself
Between；
8th step：Large scale structure piece is transported to outfitting shop's specified location, ultromotivity hydraulic flat car is withdrawn, after
It is continuous to be supported using temporary support；In painting workshop, the spray coating operations of large scale structure piece are completed, after spraying, using ultromotivity
Hydraulic flat car, then painting workshop to general assembly place is sailed out of into the large scale structure piece transport after application, carry out general assembly operation.
The Typical Disposition of the ultromotivity hydraulic flat car is：Every group of vehicle is made up of headstock, axis and transportation frame, matches somebody with somebody
It is that the form of headstock+array axis+transportation frame+array axis+transportation frame+array axis is automatic with what is postponed to put order
The car body total length of power hydraulic flat car reaches 40 meters.
Top lifting height of the large scale structure piece in workshop is more than 1.35 meters, and the exemplary height of interim pad pier is 1.35
Rice.
The ultromotivity hydraulic flat car need in advance arrange cushion block, and laid on cushion block using preceding on car body
Glued board, to increase the frictional force of car body and deck structure piece；Ultromotivity hydraulic flat car enters large scale structure piece lower section and specifies
Behind position, colligation need to be carried out at node on large scale structure piece using suspender belt and guide chain and fixed, to prevent large scale structure piece from sliding；
Before transport large scale structure piece enters painting workshop, need to lay rubber on car body cushion block in advance, to prevent from destroying large scale structure piece
Paint.
Beneficial effects of the present invention：Due to using above-mentioned technical proposal, it can not only be realized to being hinged, greatly the present invention more
The transport of the structure piece of span, solves the problems, such as that existing place haulage vehicle cannot realize the hauling operation of longspan structure piece；
And, in transportation, the means of transportation of segment axis is replaced by transportation frame, the input amount of axis is greatly reduced,
Dolly axis resource is saved, and then has saved the lease expenses of ultromotivity hydraulic flat car；Additionally, also achieving safety, height
The hauling operation of effect, improves the logistic efficiency for the treatment of of the earth piece transport, while cost of transportation is reduced, substantially reduces and applies
The work duration.
