I5 reel.
Connecting base 29 bottom described mast I11, spherical 17 is arranged at base 29 top, and mast rotates in spherical 17；
The design of spherical makes mast I arbitrarily to rotate, therefore, in the range of same Liftable, it is not necessary to repeatedly dismounting can complete
Multi-angle lifting task.
Described mast II9 connects pulley IV22, steel wire rope II24 and connects pulley IV22, walks around pulley VIII4, pulley successively
IV22 and pulley V28, is connected to the reel of hoist engine II6, connects weight bottom pulley VIII4；Driven by hoist engine II
The up and down motion of pulley VIII4, it is achieved the regulation of lifting desired height.Mast II can realize level around the rotation of pin joint simultaneously
Direction and the adjustment of vertical direction displacement.
Both sides, described mast II9 top connecting steel wire ropes III25 and steel wire rope IV26, steel wire rope III25 and steel wire rope respectively
IV26 is wound around respectively bottom pulley VI7 and pulley VII8, pulley VI7 and pulley VII8 and is connected by fixing steel wire rope respectively
Fixing.The design of actually pulley VI7 and pulley VII8 is specially the displacement fine setting that a kind of hoist engine drives weight to move up and down,
When hoist engine motion under pulley and mast drive, hoist engine I and hoist engine II for Electronic control, but as electric device,
Installing during beam column, it is difficulty with the function of inching, now needs manually to regulate and is wrapped in pulley VI7 and pulley
The steel wire rope of VII8, helps beam column installation site correct.
As shown in Figure 8, having hole in the middle of dish type connection sheet 1, hole is connected at the top shoulder of mast I11, and dish type connects sheet
For being rotationally connected between 1 and mast I11.Dish type connection sheet 1 uses steel wire rope to be fixed on by whole mast I11 by draw ring and builds
Build on thing, make mast I11 tilt.In mast I11 rotation process, do not affect it and rotate.
As it is shown in fig. 7, base includes base plate 19 and square base 18, square base 18 is fixed on base plate 19, base plate
Being connected trapezoidal connecting plate 20 between 19 with square base 18, described trapezoidal connecting plate 20 is provided with four；Each trapezoidal connecting plate 20
Vertical connection inserted link 21, inserted link 21 connects draw ring 16, and draw ring 16 connects fixing steel wire rope；Square base 18 end face has ball
Shape face 17.Base is connected on fixture 13 by static line 14, and base is provided with groove 15.
After above mast installation is installed, the anchoring of each fixing point；Lifting, steel column and steel beam lifting are to from blind again
Nearest region in district, is moved horizontally to mast lifting region in blind area, uses mast installation to install, install and be divided into two rank
Section, the first stage is the steel column lifting stage in blind area, position, underground, treats that Steel Structure Installation is complete, and civil engineering is to first floor position, so
After carry out aerial parts and carry out steel column and the installation of girder steel in second stage blind area.
When mast is removed, hang mast I top with tower crane, then remove the connection node of mast I and anchor point.
