Abstract

A kind of crane hoisting reductor rope row pinch device, comprise fixed bearing, torsion spring, through shaft, sleeve, brace panel, swing arm, reel fix shaft, rubber reel, it is characterized in that: swing arm one end arranges the circular hole that reel fix shaft can pass through, other end vertical welding sleeve, brace panel is vertically welded on the right angle that swing arm and sleeve be linked to be, and forms swing arm assembly; On rubber drum sheath reel fix shaft, through the circular hole of swing arm assembly upper end; Through shaft penetrates in the sleeve of swing arm assembly, and torsion spring is arranged on outside swing arm, is fixed by bolts on elevator box plate in the hole finally penetrating fixed bearing.The utility model has the advantage that structure is simpler, economic and practical, be easy to exchange.

Description

A kind of crane hoisting reductor rope row pinch device

technical field:

The utility model belongs to special-use vehicle technical field, particularly relates to a kind of crane hoisting reductor rope row pinch device.

background technology:

Utilize steel rope to realize hoisting of weight during crane job, steel rope being wrapped on hoisting speed reducer from level to level.Under the prerequisite of normal lift heavy thing, there is certain pretension in steel rope, therefore there will not be the disorder cable phenomenon of steel rope in winding process.When not lift heavy thing or when steel rope there is not pretension, disorder cable phenomenon will be more serious, time length had a strong impact on the life-span of steel rope, and in order to address this problem, we devise a kind of crane hoisting reductor rope row pinch device and avoid disorder cable.

summary of the invention:

The purpose of this utility model is to provide a kind of novel practical and easy crane hoisting reductor rope arrange pinch device thus avoid the generation of disorder cable situation.

It is implement like this that the utility model solves the technical scheme that its technical matters adopts: pinch device arranged by a kind of crane hoisting reductor rope, comprise fixed bearing, torsion spring, through shaft, sleeve, brace panel, swing arm, reel fix shaft, rubber reel, it is characterized in that: swing arm one end arranges the circular hole that reel fix shaft can pass through, other end vertical welding sleeve, brace panel is vertically welded on the right angle that swing arm and sleeve be linked to be, and forms swing arm assembly; On rubber drum sheath reel fix shaft, through the circular hole of swing arm assembly upper end; Through shaft penetrates in the sleeve of swing arm assembly, and torsion spring is arranged on outside swing arm, is fixed by bolts on elevator box plate in the hole finally penetrating fixed bearing.

The utility model has the advantage that structure is simpler, economic and practical, be easy to exchange.

accompanying drawing illustrates:

Fig. 1 is the front view of the utility model structure;

Fig. 2 is the birds-eye view that the utility model structure uses;

In figure: 1. fixed bearing, 2. torsion spring, 3. through shaft, 4. sleeve, 5. brace panel, 6. swing arm, 7. reel fix shaft, 8. rubber reel, 9. rope row, 10. hoisting speed reducer.

detailed description of the invention:

As shown in Figure 1 and Figure 2, a kind of crane hoisting reductor rope row pinch device, comprise fixed bearing 1, torsion spring 2, through shaft 3, sleeve 4, brace panel 5, swing arm 6, reel fix shaft 7, rubber reel 8, it is characterized in that: swing arm 6 one end arranges the circular hole that reel fix shaft 7 can pass through, other end vertical welding sleeve 4, brace panel 5 is vertically welded on the right angle that sleeve 4 and swing arm 6 be linked to be, and forms swing arm assembly; Rubber reel 8 overlaps on reel fix shaft 7, through the circular hole of swing arm 6 upper end; Through shaft 3 penetrates in the sleeve 4 of swing arm assembly, and torsion spring 2 is arranged on outside swing arm 6, is fixed by bolts on elevator box plate in the hole finally penetrating fixed bearing 1.

Embodiment: hoisting speed reducer 10 operation, the thickness of rope row 9 also can ensue change, rubber reel 8 on the effect draft link assembly band movable reel fix shaft 7 of torsion spring 2 press against rope row 9 always, rope row 9 is in compacted state always, so just can avoid the generation of disorder cable phenomenon.
