Abstract
The utility model discloses a tower crane is with electronic introduction device that hangs, breaks off relations certainly who uses when being applicable to the tower crane jacking. It installs the reel mechanism in introduction roof beam rear end including connecting in the introduction roof beam of undersetting, installs the walking wheel carrier on introduction roof beam last quarter orbital plane, installs the guide pulley in introduction roof beam front end and rear end, and rope and back rope before haulage cable is divided into, preceding rope are drawn from reel mechanism upper portion, through rear end guide pulley and the front end guide pulley on introduction roof beam upper portion, and the fixed wheel carrier front end of being expert at, restrict and follow the reel mechanism lower part and draw in the back, the snap -on wheel carrier rear end of being expert at. Special design's board hook and hoist can hoist the direct ground of following of standard festival to introducing liang chu, use manpower sparingly. The utility model discloses simple structure, operation maintenance is convenient. The introduction and the dismantlement that make the standard festival convenient and fast more that becomes. Safe and reliable need not the manpower, and the introduction device can hang certainly, break off relations certainly, saves the jacking greatly and time of falling section operation, reduction intensity of labour.
Description
（One）Technical field
This utility model belongs to derrick crane auxiliary facility and in particular to a kind of electricity of large-scale column crane mast section
Dynamic imported unit.
（Two）Background technology
At present, with the continuous development of national large nuclear-power, thermal power project, the performance requirement of large-scale derrick crane is got over
Come higher, lead to the tower body sectional dimension of large-scale derrick crane increasing.The standard knot of domestic tower crane introduces form at present
It mostly is artificial and pulls form, the shortcoming of this introduction of method is：1. it is unfavorable for construction under rugged environment；2. it is not suitable for
Casual labourer's phase engineering；3. poor stability.Therefore, design a kind of new, automatic introduction of standard knot that is being applied to heavy in section size
Device becomes urgent problem.
（Three）Content of the invention
The purpose of this utility model is to solve technical deficiency in terms of standard knot introduction for the current large-tonnage tower crane, provides one
Plant version rationally, simple to operate, soon, the derrick crane that can save a large amount of manpowers is with from suspension, from unhook for jacking speed
Electronic imported unit.
The technical scheme that this utility model is adopted is：Derrick crane is with from suspension, from the electronic imported unit tool that breaks off relations
There is introduction beam, be arranged on the drum mechanism built introducing beam rear end, be arranged on the walking round frame introduced in beam lower edge orbital plane, be arranged on
Introduce the leading block of beam front-end and back-end, haulage cable is divided into front rope and rear rope, front rope is drawn from drum mechanism built top, lead to
Cross the rear end leading block introducing beam top and front end leading block, be fixed on walking round frame front end, restrict afterwards from drum mechanism built
Portion draws, and is directly anchored to walking round frame rear end；The plate hook that rope rig connects is adapted with the short axle on suspender both sides, suspender
Following steel wire rope sling connection standard section, the short axle the inner on suspender both sides may be stuck in walking round frame.Specially designed plate hook
Standard knot directly can be lifted to introduction Liang Chu from ground with suspender.
This utility model compared with prior art, has the advantage that：
1. required size adjustment can be introduced according to standard knot and introduce beam length, have extensive versatility, it is easy to accomplish large-scale
The seriation of tower crane imported unit.
2. electronic introduction mechanism is planetary reducer with cycloidal pin teeth, 2 revs/min of this reductor rotating speed（Speed is equivalent to 35mm/
s）, it is extremely slow to introduce speed, introducing process more steady safety.Road wheel walking in a horizontal state, no skidding, it is to avoid walking
Track and road wheel wear phenomenon, decrease to walking foot wheel abrasion.
3. imported unit is introduced wheel and directly can be introduced from side, easy to disassemble.
4. standard knot can directly be lifted to introducing Liang Chu by specially designed suspender from ground, can certainly be advanced into introduction beam
Interior, convenient and swift, save manpower, greatly reduce supernumerary segment and the time of fall section, reduce labor intensity.
（Four）Brief description
Fig. 1 is the structural representation of flat-top tower crane imported unit；
Fig. 2 is the structural representation of movable arm type tower crane imported unit；
Fig. 3 is plate hook of the present utility model and suspender connection diagram；
Fig. 4 is that walking round frame of the present utility model introduces schematic diagram with suspender.
（Five）Specific embodiment
Flat-top tower crane imported unit will be introduced beam 1 by bearing pin and be connected with tower crane undersetting.Drum mechanism built 7 is arranged on draws
Enter beam 1 end, drum mechanism built 7 draws the front rope of traction respectively and rear rope is fixed in walking round frame 4.
During lifting, rope rig 2 is bent around tower crane suspension hook, and rope rig 2 two ends are separately fixed on plate hook 3.
Steel wire rope sling 6 one end is fixed on suspender 5, and the other end is fixed on standard knot.
After standard knot connects, suspender 5 and standard knot are put in walking round frame 4 by plate hook 3, and plate hook 3 passes through tower crane suspension hook
Lifting departs from suspender 5.By drum mechanism built 7 rope traction walking round frame 4, so that standard knot is entered in tower crane stock, realize mark
The introduction of quasi- section.
Movable arm type tower crane is longer due to introducing beam, needs to be connected imported unit with phase inversion next time by pull bar 8.It is introduced
Process is identical with flat-top tower crane introducing process.
Tower crane fall section, the process removing standard knot is the inverse process introduced.
