Description
Technical field
The utility model relates to a kind of flat-top tower crane, specifically a kind of flat-top tower crane fast-assembling type Tiebar structure.
Background technology
In existing design, equilibrium arm pull bar is generally divided into two sectional type or syllogic, and syllogic is made up of three different pull bars of length, and every pull bar is all round steel and be connected otic placode and be welded; As shown in Figure 1: comprise tower top structure 1, bearing pin I 2, lock pin 3, pull bar I 4, bearing pin II 5, pull bar II 61, bearing pin III 7, pull bar support I 81, pull bar III 91, equilibrium arm structure 10 and bearing pin IV 11.In installation process, need first pull bar I 4 to be installed in tower top structure 1; Again pull bar II 61 and pull bar III 91 are linked into an integrated entity with equilibrium arm structure 10; The last entirety equilibrium arm structure 10 of slinging is connected with tower top structure 1, and pull bar I 4 and pull bar II 61 are connected, and there will be following technological deficiency in connection procedure:
1, install, dismantle inconvenience.In installation process, the last entirety equilibrium arm structure 10 of slinging is connected with tower top structure 1, when pull bar I 4 is connected with pull bar II 61, because the weight ratio of pull bar II 61 is heavier, needs auxiliary hanging device, wastes resource.Because pull bar is to be welded by round steel and otic placode, if Large Towers machine, round steel can be thicker, weight can be larger, individual cannot be lifted at all, many times, in the time there is no auxiliary hanging device, need two, three installation personnels to be lifted, have again in addition installation personnel that it is connected with bearing pin.In connection procedure, because framing member is longer, if the equilibrium arm angle of slinging is improper, will be difficult in placely, installation difficulty is too large.
2, in installation process, there is potential safety hazard.In installation connection procedure, due to needs, many people lift pull bar II 61, limited space on equilibrium arm; And while slinging equilibrium arm, there is certain angle, when installation personnel stands in above, steadily do not have potential safety hazard.
3, production and processing is loaded down with trivial details.This is designed to the pull bar composition that three same form and length differ.Tiebar structure by round steel be connected otic placode and be welded, pull bar one end is monaural plate, one end is ears plate in addition, there are 4 important weld seams monaural plate one end, there are 8 important weld seams ears plate one end, and every pull bar adds up to 12 important weld seams, and three pull bars have 36 important weld seams, welding capacity is large especially, and comparision of production is loaded down with trivial details.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of flat-top tower crane fast-assembling type Tiebar structure, and while making installation, dismounting tower machine equilibrium arm, the connection of pull bar is more convenient, efficient, safety.
To achieve these goals, the technical solution adopted in the utility model is: a kind of flat-top tower crane fast-assembling type Tiebar structure, comprises tower top structure, bearing pin I, lock pin, pull bar I, bearing pin II, bearing pin III, pull bar II, pull bar support, equilibrium arm structure and bearing pin IV; Pull bar I is connected in tower top structure and with lock pin and is locked by bearing pin I, and pull bar II is connected in equilibrium arm structure by bearing pin IV, and is positioned on pull bar support; Also comprise arm-tie, arm-tie one end is connected in pull bar I by bearing pin II, and the other end is connected with pull bar II by bearing pin III; Pull bar II, pull bar I, arm-tie are respectively long draw, short rod, short arm-tie, and shorten successively.
The relative ground of equilibrium arm structure forms the angle that upwarps of 1-2 degree.
Pull bar II, pull bar I are monaural plate structure, and arm-tie is ears plate structure.
Compared with existing device: in the utility model, pull bar is divided into a longer pull bar, the short rod of a shorter arm-tie and a moderate length, in installation process, utilize artificial the hold up arm-tie that weight is lighter the form being connected with long draw, there is following advantage: 1, equilibrium arm entirety is sling and after tower top connects, equilibrium arm is tilted slightly, an installation personnel can easily hold up arm-tie, another installation personnel connects arm-tie and pull bar II by bearing pin III, very convenient, efficient; 2, in installation process, the angle of equilibrium arm and horizontal surface is very little, above installation personnel can pulsation-free stands in.Because the utility model adopts the version of short arm-tie, junction framing member lightweight, installation personnel can easily hold up arm-tie, and packs smoothly connection bearing pin into, and whole process is convenient, efficient, safety; 3, long draw is for to be monaural plate structure with short rod, totally 16 important weld seams; On short arm-tie, only have 4 general little weld seams; So welding capacity reduces greatly, production and processing gets up to be more prone to, simple.
