Description
Technical field
The present invention 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 the pull bar that three length is different, and every root 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, pin shaft II 5, pull bar II 61, pin shaft 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; Last entirety equilibrium arm structure 10 of slinging is connected with tower top structure 1, pull bar I 4 and pull bar II 61 is connected, there will be following technological deficiency in connection procedure:
1, install, dismantle inconvenience.In installation process, last entirety equilibrium arm structure 10 of slinging is connected with tower top structure 1, when being connected with pull bar II 61 by pull bar I 4, because the weight ratio of pull bar II 61 is heavier, needs auxiliary hanging device, namely wastes resource.Because pull bar is 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 when there is no auxiliary hanging device, needing two, three installation personnels to be lifted, having installation personnel that it is good with pinned connection in addition again.In connection procedure, because framing member is longer, if equilibrium arm angle of slinging is improper, will be difficult in place, installation difficulty is too large.
2, there is potential safety hazard in installation process.In installation connection procedure, due to needs, many people lift pull bar II 61, limited space on equilibrium arm; And sling equilibrium arm time have certain angle, steadily there is not potential safety hazard when installation personnel stands in above.
3, production and processing is loaded down with trivial details.This is designed to three same form and the pull bar that length differs forms.Tiebar structure by round steel be connected otic placode and be welded, pull bar one end is monaural plate, one end is bi-lug plate in addition, there are 4 important weld seams monaural plate one end, there are 8 important weld seams bi-lug plate one end, and every root 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
For above-mentioned prior art Problems existing, the invention provides a kind of flat-top tower crane fast-assembling type Tiebar structure, when making installation, dismounting tower machine equilibrium arm, the connection of pull bar is more convenient, efficient, safety.
To achieve these goals, the technical solution used in the present invention 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, pin shaft II, pin shaft III, pull bar II, pull bar support, equilibrium arm structure and bearing pin IV; Pull bar I to be connected in tower top structure by bearing pin I and with lock pin locking, pull bar II bearing pin IV is connected in equilibrium arm structure, and is positioned on pull bar support; Also comprise arm-tie, arm-tie one end pin shaft II is connected on pull bar I, and the other end is connected with pull bar II by pin shaft III; Pull bar II, pull bar I, arm-tie are respectively long draw, short rod, short arm-tie, and shorten successively.
What the relative ground of equilibrium arm structure formed 1-2 degree upwarps angle.
Pull bar II, pull bar I are monaural plate structure, and arm-tie is bi-lug plate structure.
Compared with existing device: in the present invention, pull bar is divided into a longer pull bar, the arm-tie of one piece shorter and the short rod of a moderate length, in installation process, utilize the form that the artificial arm-tie holding up lighter in weight is also connected with long draw, there is following advantage: 1, equilibrium arm entirety is sling and after tower top connects, make equilibrium arm shallow decline, an installation personnel easily can hold up arm-tie, arm-tie and pull bar II connect by pin shaft III by another installation personnel, very convenient, efficient; 2, in installation process, the angle of equilibrium arm and horizontal surface is very little, and installation personnel can above pulsation-free stands in.Because the present invention adopts the version of short arm-tie, junction framing member lightweight, installation personnel easily can hold up arm-tie, and loads smoothly and connect bearing pin, and whole process is convenient, efficient, safety; 3, long draw is for be monaural plate structure with short rod, totally 16 important weld seams; 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, simply.
Accompanying drawing explanation
Fig. 1 is existing apparatus structural representation;
Fig. 2 is structural representation of the present invention.
In figure: 1, tower top structure, 2, bearing pin I, 3, lock pin, 4, pull bar I, 5, pin shaft II, 6, arm-tie, 61, pull bar II, 7, pin shaft III, 8, pull bar II, 81, pull bar support I, 9, pull bar support, 91, pull bar III, 10, equilibrium arm structure, 11, bearing pin IV.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 2, a kind of flat-top tower crane fast-assembling type Tiebar structure, comprises tower top structure 1, bearing pin I 2, lock pin 3, pull bar I 4, pin shaft II 5, pin shaft III 7, pull bar II 8, pull bar support 9, equilibrium arm structure 10 and bearing pin IV 11; Pull bar I 4 is connected in tower top structure 1 by bearing pin I 2 and also locks with lock pin 3, and pull bar II 8 bearing pin IV 11 is connected in equilibrium arm structure 10, and is positioned on pull bar support 9; Also comprise arm-tie 6, arm-tie 6 one end pin shaft II 5 is connected on pull bar I 4, and the other end is connected with pull bar II 8 by pin shaft III 7; Pull bar II 8, pull bar I 4, arm-tie 6 are respectively long draw, short rod, short arm-tie, and shorten successively.
In installation process, be connected in tower top structure 1 with bearing pin I 2 by pull bar I 4 and also lock with lock pin 3, make pull bar I 4 can not hang down, arm-tie 6 pin shaft II 5 is connected on pull bar I 4; Again pull bar II 8 bearing pin IV 11 is connected in equilibrium arm structure 10, and is positioned on pull bar support 9; Finally equilibrium arm structure 10 entirety is sling after connecting with tower top structure 1, make equilibrium arm structure 10 shallow decline, an installation personnel can easily hold up arm-tie 6, and arm-tie 6 and pull bar II 8 pin shaft III 7 connect by another installation personnel, very convenient, efficient.
As improvement of the present invention, equilibrium arm structure 10 relatively ground form 1-2 degree upwarp angle, installation personnel can above pulsation-free stands in.Due to the version that arm-tie in the present invention 6 is short arm-tie, junction framing member lightweight, installation personnel easily can hold up arm-tie, installs, and whole process is convenient, efficient, safety.
Further, pull bar II 8 and pull bar I 4 are monaural plate structure, totally 16 weld seams, and arm-tie 6 only has 4 general little weld seams, and welding capacity reduces greatly, and production and processing gets up to be more prone to, simply.
Principle of work of the present invention is as follows: by pull bar length classifying rationally, pull bar is divided into three sections of versions connected: the pull bar II 8 be connected with equilibrium arm structure 10 is made the longer structure of length, is placed on pull bar support 9 during installation; The pull bar I 4 be connected with tower top structure 1 is made moderate length and shorter structure, and locks with lock pin 3, make pull bar I can not hang down; One section, centre arm-tie 6 is made length short, lightweight structure, very convenient, efficient, safety during installation.
