Abstract
The invention relates to a steel wire rope loosening-resisting rope protecting device for a crane. The protecting device comprises a crane rack, connecting frames are installed on one side of the crane rack at intervals, holes are formed in the connecting frames, rotary shafts are formed in the holes, the rotary shafts are arranged perpendicular to the connecting frames, steel wire rope guiding wheels are installed on the rotary shafts through bearings, the steel wire rope guiding wheels are arranged between the two connecting frames, and an approach switch is arranged on the part, between the two connecting frames, of the crane rack. The output ends of the rotary shafts are connected with a winch controlling the rotary shafts to rotate, and the approach switch is connected with the winch through electric signals. The steel wire rope loosening-resisting rope protecting device for the crane is reasonable in structure, easy and convenient to operate and safe and reliable to use, the tightness of a steel wire rope is controlled through the approach switch, and the service life of the steel wire rope is effectively prolonged. The steel wire rope loosening-resisting rope protecting device for the crane is flexible to use, and the steel wire rope loosening-resisting rope protecting device for the crane can be installed at a required place according to different application occasions.
Description
Technical field
The present invention relates to hoisting crane accessory equipment technical field, the anti-rope-loosing protection device of steel rope for especially a kind of crane.
Background technology
Crane claims again loop wheel machine peculiar to vessel, deck crane, is a kind of large deck machinery on ship, and it is a kind of equipment of ship loading and unloading goods, and hydraulic pressure crane is a kind of cargo handling appliance generally using on boats and ships.
Crane is mainly used in the handling of Cargo On Deck, in the process of unloading, in order to prevent that steel rope from emitting long; cause steel cable loosening, crooked; thereby cause steel rope malalignment, mutual winding, confusion when reclaiming, even damage, just need to arrange steel rope and loosen fender guard.But steel rope of the prior art loosens fender guard, its complex structure, takes up room large, and cost is high, troublesome poeration, and reliability of service is poor, and weak effect affects the normal use of crane.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides the anti-rope-loosing protection device of steel rope for a kind of crane rational in infrastructure, thereby improves the safety and reliability of crane, extends the service life of steel rope.
The technical solution adopted in the present invention is as follows:
The anti-rope-loosing protection device of steel rope for a kind of crane, comprise crane frame, described crane frame one side interval is provided with link span, on described link span, have hole, described hole internal memory is crossed rotating shaft, and described rotating shaft and link span at right angle setting, be provided with steel rope guide wheel by bearing in described rotating shaft, described steel rope guide wheel, between two link spans, is also provided with approach switch in the crane frame between two link spans; The mouth of rotating shaft connects the winch of controlling its rotation, and described approach switch is connected with winch by electric signal.
Further improvement as technique scheme:
Described link span end is welded in crane frame.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, easy and simple to handle, safe and reliable, controls the degree of tightness of steel rope by approach switch, and actv. has extended the service life of steel rope.It uses flexibly, according to different application occasion, can easily the present invention be installed on to desired location.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, crane frame; 2, link span; 3, approach switch; 4, steel rope guide wheel; 5, bearing; 6, rotating shaft.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the anti-rope-loosing protection device of steel rope for the crane of the present embodiment, comprise crane frame 1, crane frame 1 one side intervals are provided with link span 2, on link span 2, have hole, and hole internal memory is crossed rotating shaft 6, rotating shaft 6 and link span 2 at right angle settings, in rotating shaft 6, by bearing 5, steel rope guide wheel 4 is installed, steel rope guide wheel 4, between two link spans 2, is also provided with approach switch 3 in the crane frame 1 between two link spans 2; The mouth of rotating shaft 6 connects the winch of controlling its rotation, and approach switch 3 is connected with winch by electric signal.
In actual use procedure, when steel rope is constantly emitted on steel rope guide wheel 4, until goods unloads, approach switch 3 detects steel rope and emits, and now provides signal to winch, controls winch and stops continuing to put rope action, protection steel rope.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
