Embodiment
As shown in Figure 1, a kind of tower crane two sides jacking stock, introduces the top of crossbeam 3 and is equipped with lifting cross beam 2, introduce under crossbeam 3
End is connected with slidable coaster 4, and lifting cross beam 2 is connected with coaster 4 by steel wire rope 8, and 2 upper surface of lifting cross beam, which is connected with, hangs
Hook pulley blocks, 4 lower end of coaster are connected with suspender 1, introduce 3 one end of crossbeam and are equipped with electric block 7, introduce crossbeam 3 and are equipped with cross
Beam 11, introduces crossbeam 3 and is equipped with angle pulley 15, the top of rood beam 11 is equipped with transition segment 13, and 13 side of transition segment is connected with drawing
Bar 12, the other end of pull rod 12 are connected with introducing 3 end face of crossbeam, are introduced the lower section of crossbeam 3 and are equipped with stock 9, stock 9 is equipped with stock
Piece 6 afterwards, the rice word beam both ends of stock 9 are equipped with stock or so piece 5.Angle pulley 15 is equipped with crossbeam 3 is introduced, it is ensured that aerial
Realize that piece after stock becomes the conversion of anter, realize that 180 ° of tower crane can be worked after turning to lifting guide support adding.
The lower section of the suspender 1 clamping standard knot 10.
As shown in Fig. 2, positive introduce standard knot, start control electric block 7, by haulage cable 8, pull trolley band
Standard knot 10 together to enter in stock 9, received after 10 main chord of standard knot of introducing aligns with 10 main chord of tower-body standard section
Contracting oil cylinder, makes 10 connection place of standard knot match, squeezes into connecting link pin, and is connected, and unloads the attachment pegs of suspender 1 and standard knot
Axis, controls electric block 7, trolley is removed stock 9.Continue retract cylinder, rood beam 11 and tower body section are linked up, such as after
Continuous plus next section, this connection can use axis pin temporarily with stock 9；Suspender 1 is unloaded from trolley, continues to repeat jacking process just
The height of required tower crane can be jacked.When having jacked last standard knot, to put into before normal use must with 8 it is normal
Pin shaft joint rood beam and tower body section, and interface channel.
As shown in figure 3, reversely introduce standard knot 10, if tower crane needs supernumerary segment, and when supernumerary segment direction is opposite with original direction, then
The steel wire rope 8 introduced on beam need to be first pulled down, is then attached to after stock in the flapper on 6 top of piece.At the same time by lifting hook pulley group
Suspension hook is pulled down, and loads onto lifting cross beam, and steel wire rope thereon is connected on the otic placode of flapper.Pull down the work on the top of piece 6 after stock
The connection bolt of piece, while lifting cross beam 2 and the flapper on the top of piece 6 after the pulling stock of electric block 7 are utilized, after being pulled down
Unclamp and introduce steel wire rope 14, turn round tower crane, flapper is positioned on floor or ground.
Pull rod 12 is pulled down, then pulls down again and introduces the axis pin that crossbeam 3 is connected with rood beam 11, and crossbeam 3 will be introduced
Opposite direction moves to required position, then is attached with axis pin, while has reconnected pull rod with axis pin introducing 3 opposite side of crossbeam
12。
As shown in figure 4, small truck position is introduced in adjustment, the flapper on 6 top of piece after stock is sling with lifting cross beam 2, will be introduced
