Description
Technical field
The present invention relates to machinery manufacturing technology field, more particularly to a kind of 1600T masts arm frame always spells technique.
Background technology
With the long-range strategic demand of country, the long-term interest of country name race, it is extremely great to develop the meaning of marine resources, meaning
Justice is very far-reaching.With the continuous development of extra large work project, higher requirement it is also proposed to its supporting hardware device, build now
The 1600T masts made hang a loop wheel machine for current largest domestic, and the volume that it can solve extra large work project is big, weight weight, difficult
At sea to lift by crane this bottleneck.1600T masts are hung to be made up of arm support, reversing chassis, upper pillar stand and lower pillar stand, its arm support length
Long, weight weight, construction precision requires the high emphasis and difficult point for turning into whole mast and hanging construction.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of 1600T mast arm framves that can shorten construction period always to spell
Technique.
In order to solve the above technical problems, the technical scheme is that：A kind of 1600T masts arm frame always spells technique, its
Innovative point is：Turn including group, precision size Control, the lifting of arm support workshop, arm support in arm support workshop moulding bed arrangement, arm support workshop
Fortune, 1600T crane barges are lifted, and are comprised the following steps that：

（3）Precision size Control：
Integral marking carries out bore hole to arm support hinge after the completion of arm support welding：Respectively towards arm support root on the basis of auxiliary hook otic placode center
Rule in portion；Surplus is not processed on the outside of arm support steel bushing, and bore hole installation need to be carried out to the structure at the hinge of arm support root, and last basis is drawn
Line is processed to arm support steel bushing endoporus；
（4）Arm support workshop lifts：Weight is about 510T after arm support is always spelled, and is lifted using two 200T+200T drivings；Lifting
Preceding preparation：150T shackles 4；4, φ 87*16m steel wire ropes；
（5）Arm support is transported：
Arm support transhipment uses 2 200T, and 1 280T flat car is transported through：
1）Structural integrity need to be used, weld seam is transported through through the qualified transferring platform of nondestructive testing；
2）After the completion of arm support overall package, shopwork is carried out out, needs to arrange excessive slope in advance if the workshop gradient is excessive,
Flat car transferring platform and chock reference by location drawing, scene adjust according to actual conditions, and chock is placed on the structure prime time as far as possible
Place；
3）Arm support head plate car scene carries out place mat using rail；
（6）1600T crane barges are lifted：
Prepare before lifting：4, φ 135*35M steel wire ropes；150T shackles 4.
Further, the step（2）In, the requirement of arm support linearity is：Every meter is less than 2mm, and total length is less than 5mm；Arm support
Requirement for horizontality is：≤6mm.
Further, the step（4）And step（6）Lifting points for attention be：Before segmental hoisting, each hang is checked
Whether point, steel wire rope and shackle are defective, are then reeved according to process program and shackle；Lifting process needs slowly, steadily,
Abnormal conditions occur need to stop lifting immediately, and pending fault continues operation after excluding；Increase anti-shake rope, the side of being conveniently adjusted before lifting
To.
The advantage of the invention is that：Whole arm support is up to 99 meters, and weight has reached 510T, to shorten construction period, it is ensured that
Welding quality, it is classified as arm support root, group during middle part and these three parts of head are carried out, general assembly being carried out after the completion for the treatment of middle group.
Arm support is because length is longer and arm support main couple is body structure, and inside is provided with dividing plate, and we employ the form of segmentation group
Carry out group is prefabricated, and scene carries out group's corner weld submerged arc automatic welding using oblique gesture moulding bed, shortens arm support in this way
The construction period of nearly half.
