Correspondence position be equipped with the second abutted flange, mounting and adjusting crossbeam 5 is connected between the first abutted flange and the second abutted flange,
The both ends of mounting and adjusting crossbeam 5 are connected with the first abutted flange and the second abutted flange respectively by bolt；In rotating frame 1
Before lower end is hinged with fixed seat, rotating frame 1 is first connected by mounting and adjusting crossbeam 5 with fixed seat, in the lower end of rotating frame 1
After hingedly being installed with fixed seat, then mounting and adjusting crossbeam 5 removed, avoid installation (or during use), rotation lower fulcrum is held
By the gravity in plummet direction, rotation lower fulcrum is set to be solely subjected to the radial load of horizontal direction.
Further, guide rail is made of three sections of tracks, is respectively track epimere 2, track stage casing 3 and track hypomere 4.
Further, the lowermost track is laterally equipped with brake plate 10, and the bottom of guide rail is equipped with buffer 9；Set on guide rail
Have sublance trolley, sublance trolley is moved up and down along guide rail, brake plate 10 act as when sublance trolley decrease beyond extreme position and
When electic protection fails, the sublance pawl on sublance trolley is in contact with this steel plate, and friction occurs and produces frictional force brakes, really
Protecting sublance body can not be inserted into molten steel, avoid accident, can be by boom hoist cable by sublance trolley weight when troubleshooting
Newly carry back working position；Buffer 9 plays cushioning effect for sublance trolley.
Further, fixed bottom plate 13 is installed with fixed seat, fixed bottom plate 13 is connected by square steel 14 and overarm brace 6
Connect.
Further, multiple coupling bolts 15 are vertically distributed with rotating frame 1, rotating frame 1 passes through connection

Further, multiple bolt hand holes 17 are vertically distributed on rotating frame 1, bolt hand hole 17 is arranged at connection
15 side of bolt, easy to the dismounting of coupling bolt 15.
The operation principle of the present invention：
The guide rail and rotating frame 1 that the present apparatus is spliced by multiple tracks form, and fulcrum is rotated in sublance in Pivot axle
On platform 18.Pivot axle lower fulcrum includes mounting and adjusting crossbeam 5, overarm brace 6, oscillating bearing 7, bearing block 8, axis pin
11st, axis pin base 12, fixed bottom plate 13 and square steel 14.Track is made of track epimere 2, track stage casing 3, track hypomere 4.Multiple rails
Road is connected to become an entirety by bolt rotating frame 1.
Guide rail is divided into three sections of tracks, there is the gap of 2mm between every section of track.Easy to manufacture and transport.If logistics condition
Allow, every section of track welds on horizontal workbench after the completion of assembly, whole Transporting；If logistics condition does not allow, segmentation
Transport, site welding, the maximum unfitness of butt joint of orbital plane are less than or equal to 0.15mm.
Rotating frame 1 except lower fulcrum and top connecting plate with 200 channel steel support, remaining with 126 or 75 channel steel, gently
Quantitative design, mitigates weight.Bolt hand hole 17 at 10 is opened up on rotating frame 1, is easily installed and replaces track and rotating frame 1
Between coupling bolt 15.
Brake plate 10 is welded on track hypomere 4, is act as when sublance trolley decrease beyond extreme position and electic protection loses
During effect, sublance pawl is in contact with this steel plate, and friction occurs and produces frictional force brakes, it is ensured that sublance body can not be inserted into molten steel
In, avoid accident.When troubleshooting, sublance trolley can be carried back again by working position by boom hoist cable.
Fulcrum is subjected to the gravity in plummet direction in (or during use) rotation axis during installation, and bears level side
To radial load.(or during use) rotation axis lower fulcrum cannot bear the gravity in plummet direction during installation, be solely subjected to level
The radial load in direction.
The installation process of the present apparatus：
First track epimere 2, track stage casing 3, track hypomere 4 are coupled with rotating frame 1, fulcrum in rotation axis is then installed
With sublance rotating platform 18.Coordinate installation rotation axis lower fulcrum again.
Fulcrum is subjected to the gravity in plummet direction in (or during use) rotation axis during installation, and bears level side
To radial load.(or during use) rotation axis lower fulcrum cannot bear the gravity in plummet direction during installation, be solely subjected to level
The radial load in direction.
Crossbeam role is adjusted as interim installation or maintenance stent.Due to the limitation of bulk (free height~363),
Before mounting and adjusting crossbeam 5, it is necessary to axis pin 11 is first installed by figure；I.e. must be by figure first by axis pin 11 and bearing block 8, axis pin base 12
It is installed together, otherwise the installation of crossbeam interference axis pin 11；If first installing crossbeam, installation axis pin 11 will be unable to.Treat rotation axis
After up/down fulcrum mounting and adjusting, crossbeam is unloaded by figure dismounting.
During in-site installation after related parts are adjusted, fixed bottom plate 13 and square steel 14 are continuously welded by figure.
In conclusion light-weight design, alleviates weight of equipment；Track section, easy to process and transport；Set on track
Sublance mechanical anti-falling Machine guarding, it is safer；Track is connected with the bolt of frame adds bolt hand hole 17, convenient tight
Firmware installation is safeguarded.
The interest field for being only presently preferred embodiments of the present invention, the present invention cannot being limited with this certainly above,
Therefore the equivalence changes made according to scope of the present invention patent, still belong to protection scope of the present invention.
