Description
Technical field
The present invention relates to pipeline construction equipment, the rising mechanism of a kind of oil cylinder internally-arranged type super large voussoir inner tube of a tyre core.
Background technology
" 13 " planning end China long-distance oil & gas pipeline total kilometrage will be more than 160,000 kilometers, and natural gas will become the energy and disappear
Take the important bridge changed by high-carbon to low-carbon (LC).Building and will have Sino-Russian pipeline, west at the defeated natural gas line of the length built at present
Gas east defeated four lines etc., their backbone caliber is all 1422mm or 1219mm, and the currently used inner tube of a tyre core of China is the most multiplex
In bending the less steel pipe that caliber is below 1016mm, therefore, design, manufacture and bend the inner tube of a tyre core of large-scale steel pipe along with Large Tube
The laying of line and extremely urgent, market is considerable, has very important strategic importance.
At present, the difficult point of the inner tube of a tyre core that design research and development bend large-scale steel pipe essentially consists in: bend the bending machine of large-scale steel pipe
Its bend pipe top lift reaches more than 1200 ton, and during bend pipe, inner tube of a tyre core wants rising by steel pipe stretching, and it also to bear identical bending
Power.Fall apart if insufficient strength inner tube of a tyre core is fragile, and the elastic bad permanent deformation that is easily generated, this is have to solve at present
A difficult problem.
Summary of the invention
The invention aims to provide rising of a kind of oil cylinder internally-arranged type super large voussoir inner tube of a tyre core solving an above-mentioned difficult problem
Play mechanism, make during bending machine bend pipe, to prevent steel pipe to lose round, wrinkling, there is enough structural strengths and counter-bending deformability,
Service life is long, easy to maintenance.
The technical scheme is that
A kind of rising mechanism of oil cylinder internally-arranged type super large voussoir inner tube of a tyre core, it is characterised in that: include that two pieces are positioned at same flat
Face and the rise plate being arranged in parallel, two pieces be respectively arranged immediately below rise plate under rise plate, be erected on rise plate upper surface also
Multiple arch upper support frames of being connected as one by two blocks of rise plates, it is erected on down the plate lower surface being connected by the plate that rises under two pieces of rising
Bracing frame under the multiple arch being integrated, be located at along rise plate length direction two pieces of rise plate lower surfaces multiple rise slide blocks,
The position of corresponding rise slide block be located under two pieces the plate upper surface that rises multiple under rise slide block, be located at two blocks of rise plates and corresponding
Under rise four couple of the forward and backward avris of plate rise reply plate；The quantity of the rise slide block on two blocks of rise plates is equal, rises on plate under two pieces
Under the rise quantity of slide block equal, described rise slide block with under the slider shape that rises identical, symmetrical, have the most corresponding with bottom surface in
The end face of identical angle and bottom surface are the transition face of identical angle；The every pair of reply plate that rises is by the reply plate and corresponding that goes up
Under rise reply plate composition, described go up reply plate and under rise reply plate be respectively equipped with corresponding gradient consistent guiding reply
Face.
The rising mechanism of above-mentioned oil cylinder internally-arranged type super large voussoir inner tube of a tyre core, described rise slide block and under rise the end face of slide block
Being 8 ° of angles with bottom surface, transition face and bottom surface are 36 ° of angles.
The invention has the beneficial effects as follows: the parallel moving mechanism of the present invention and inner tube of a tyre core and translation bit combination mechanism are formed steel
The supporting construction of pipe, compact conformation, acts freely, and makes to prevent during bending machine bend pipe steel pipe from losing circle, wrinkling, has enough structures
Intensity and counter-bending deformability, safe and reliable, it is ensured that being smoothed out of bent tube technique, improve bending quality greatly,
Being applicable to the bend pipe operation of China's maximum caliber (1422mm), service life is long, easy to maintenance.
