Abstract
The invention discloses a tower crane cargo boom pull rod structure. The tower crane cargo boom pull rod structure comprises a single tower top pulley (3), an inner pull plate (1), an outer pull plate (2), an inner pull rod (5) and an outer pull rod (6), and further comprises an inner adjusting plate (7) and an outer adjusting plate (8), wherein the two ends of the inner adjusting plate (7) are connected with the inner pull plate (1) and the inner pull rod (5) respectively, and the two ends of the outer adjusting plate (8) are connected with the outer pull plate (2) and the outer pull rod (6) respectively. The tower crane cargo boom pull rod structure has the beneficial effects that a plate pulling device structure is omitted, the number of tower top pulley sets is decreased, cargo boom pull rod manufacturing becomes simple, and cost is reduced; and a pull rod is easily installed in place by additionally arranging the inner adjusting plate and the outer adjusting plate.
Description
Technical field
The present invention relates to a kind of Tiebar structure, particularly relate to a kind of derrick runway girder Tiebar structure.
Background technology
The design of existing derrick runway girder pull bar, as shown in Fig. 1-Fig. 7, crane arm pull bar adopts plate pulling device structure, tower top to adopt double pulleies unit structure.When crane arm pull bar is installed, plate pulling device and tower top outer tie rod arm-tie, successively by being fixed on plate pulling device after tower top pulley, plate pulling device pulley, tower top pulley, finally couple together with bearing pin by hoist rope.
The shortcoming of said structure is that assembly pulley is many, structure heavy, it is complicated to manufacture, cost is high, and be described as follows: 1, because tower top assembly pulley has two, plate pulling device also has one, and cause assembly pulley quantity many, cost is high; 2, because the structural weight of plate pulling device is large, parts are many, cause manufacturing cost high; 3, structure member is many, installs complicated.
Summary of the invention
For above-mentioned existing technical matters, the invention provides a kind of derrick runway girder Tiebar structure, make the manufacture of derrick runway girder pull bar simple, with low cost, easy for installation.
For achieving the above object, the invention provides a kind of derrick runway girder Tiebar structure, comprise single tower top pulley, interior arm-tie, outer arm-tie, draw-in bar, outside link, also comprise the interior regulating plate that two ends connect interior arm-tie, draw-in bar respectively, and two ends connect the outer regulating plate of outer arm-tie, outside link respectively.
Further, also comprise installation steel rope, it is directly fixed on outside link after tower top pulley.
Further, also comprise installation steel rope, it is directly fixed on draw-in bar after tower top pulley.
The present invention by cancelling plate pulling device structure, and decreases tower top assembly pulley quantity, makes that the manufacture of crane arm pull bar becomes simply, cost reduction, by increasing inside and outside regulating plate, makes pull bar easily in place in installation process.There is following beneficial effect:
1, because version is simple, parts are few, so manufacturing process becomes convenient and swift.
2, because lightweight construction, assembly pulley are few, so the cost designed and produced reduces.
3, because assembling parts tails off, so installation process also becomes quick.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As Figure 8-Figure 10, the present invention includes and steel rope, single tower top pulley 3, interior arm-tie 1, outer arm-tie 2, draw-in bar 5, outside link 6 are installed, also comprise the interior regulating plate 7 that two ends connect interior arm-tie 1, draw-in bar 5 respectively, and two ends connect the outer regulating plate 8 of outer arm-tie 2, outside link 6 respectively.
When crane arm pull bar is installed, outside link 6 is generally first installed draw-in bar 5 is installed again, be directly fixed on outside link 6 so first installation steel rope to be walked around tower top pulley 3, regulated the installation site of outer arm-tie 2, outside link 6 by outer regulating plate 8; Then installation steel rope being walked around tower top pulley 3 is directly fixed on draw-in bar 5, is regulated the installation site of interior arm-tie 1, draw-in bar 5 by interior regulating plate 7.
Tower top of the present invention adopts single-sheaved block group, eliminates crane arm pull bar plate pulling device, by regulating plate inside and outside crane arm pull bar, crane arm pull bar is had when mounted and regulates function in place, has that parts are few, structure light, low cost and other advantages.
By applying this technology, XGT80DQ(5610-6) crane arm pull bar not only production and installation process in very convenient, quick, also shorten production cycle and productive costs.Also to the design of other products, there is important reference value and using value simultaneously.
