In deficiency.
To achieve the above object, the utility model provides following technical scheme：
The embodiment of the present application discloses a kind of derrick crane for preventing steel wire rope from departing from, the derrick crane large arm top
Portion is connected with below first pulley, the first pulley and is provided with second pulley, and the second pulley is mounted on a crossbeam
One end, the steel wire rope sequentially passes through that to be connected to the crossbeam after first pulley, second pulley, the 3rd pulley of connecting shackle remote
From one end of the second pulley, the crossbeam two ends be may be reversed be connected at the top of the large arm respectively, and the second pulley is hung down
Directly in the first pulley.
It is preferred that, in the above-mentioned derrick crane for preventing steel wire rope from departing from, the second pulley two ends are towards described
Steel wire rope one end has been each extended over to be bolted between adjutage, two adjutage.
It is preferred that, in the above-mentioned derrick crane for preventing steel wire rope from departing from, the crossbeam is provided with a vertical pivot, described
Vertical axis is connected to the crossbeam, and the steel wire rope is connected and fixed on the vertical pivot.
It is preferred that, in the above-mentioned derrick crane for preventing steel wire rope from departing from, gear rope bar is provided with the suspension hook.
It is preferred that, in the above-mentioned derrick crane for preventing steel wire rope from departing from, the 3rd pulley is connected to a support,
The suspension hook is rotationally connected with the support.
Compared with prior art, advantage of the present utility model is：
1st, the effect of second pulley causes steel wire rope to remain vertical in first pulley to one end between second pulley
State, is effectively prevented the danger that steel wire rope departs from first pulley；
2nd, crossbeam upset is connected to large arm so that second pulley is in the underface of first pulley all the time, it is therefore prevented that steel wire
Rope departs from；
3rd, the effect of adjutage causes steel wire rope without departing from second pulley, further ensures anti-detachment；
4th, vertical axis be connected to crossbeam effect be discharge steel wire rope itself torsion, it is ensured that steel wire rope will not twisting
Together；
5th, gear rope bar makes to prevent article from departing from during suspension hook hanging object product；
6th, suspension hook rotates connection function and is to discharge the torsion for slinging article.
Brief description of the drawings
, below will be to embodiment or existing in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments described in application, for those of ordinary skill in the art, on the premise of not paying creative work,
Other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 show the tower type crane structure schematic diagram for preventing that steel wire rope from departing from the utility model specific embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Detailed description, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole implementation
Example.Based on the embodiment in the utility model, those of ordinary skill in the art institute on the premise of creative work is not made
The every other embodiment obtained, belongs to the scope of the utility model protection.
With reference to shown in Fig. 1, the derrick crane for preventing steel wire rope from departing from, the top of derrick crane large arm 4 is connected with first
Pulley 1, the lower section of first pulley 1 is provided with second pulley 2, and second pulley 2 is mounted on the one end of a crossbeam 6, and steel wire rope 5 is successively
The one end of crossbeam 6 away from second pulley 2 is connected to after first pulley 1, second pulley 2, the 3rd pulley 3 of connecting shackle 7,
The two ends of crossbeam 6 may be reversed respectively is connected to the top of large arm 4, and second pulley 2 is perpendicular to first pulley 1.
The effect of second pulley causes steel wire rope to remain vertical shape in first pulley to one end between second pulley
State, is effectively prevented the danger that steel wire rope departs from first pulley；Crossbeam upset is connected to large arm so that second pulley is located all the time
In the underface of first pulley, it is therefore prevented that steel wire rope departs from.
Further, the two ends of second pulley 2 have been each extended between adjutage 8, two adjutages 8 towards the one end of steel wire rope 5
It is bolted.
The effect of adjutage causes steel wire rope without departing from second pulley, further ensures anti-detachment.
Further, crossbeam 6 is provided with a vertical pivot 11, and vertical pivot 11 is rotationally connected with crossbeam 6, and steel wire rope 5 is connected and fixed on
Vertical pivot 11.
The effect that vertical axis is connected to crossbeam is to discharge steel wire rope itself torsion, it is ensured that steel wire rope will not hinge in
Together.
Further, gear rope bar 9 is provided with suspension hook 7.
Gear rope bar makes to prevent article from departing from during suspension hook hanging object product.
Further, the 3rd pulley 3 is connected to a support 10, and suspension hook 7 is rotationally connected with support 10.
Suspension hook rotates connection function and is to discharge the torsion for slinging article.
