Description
Technical field
The utility model relates to a kind of power construction Work tool, particularly a kind of pulley mechanism for electric power cable unwrapping wire.
Background technology
In power construction, maintenance engineering, often there are all kinds of electric power cables, for example wire, cable, steel strand wire, unwrapping wire operation; Pulley is that unwrapping wire operates requisite Work tool.Application shows, the pulley that unwrapping wire is used at present exists following problem:
The central shaft of pulley adopts rolling friction, and rubbing fastness is not high, and especially in use bearing easily enters soil, accelerates bearing damage.
The pulley of ting model is not suitable for large-section lead, and the pulley weight of model is large greatly, cost is high.
Pulley chute is narrow, meets terminal by chance and is difficult for passing through smoothly, need set a watch on.Even if someone guards, once cause card line also to need to stop unwrapping wire operation, this measure very easily causes that wire is impaired, the disconnected bar of bar is even fallen in cross-arm distortion.
Above pulley, sealing part hook needs wiring to fix in use, if process the bad card line that also easily causes, has increased unsafe factor.
Summary of the invention
The purpose of this utility model is to provide a kind of pulley mechanism for electric power cable unwrapping wire, to solve complex structure that prior art exists, not easy to operate, the problem such as easy care not.
In order to address the above problem, the technical scheme that the utility model provides is as follows:
For a pulley mechanism for electric power cable unwrapping wire, it comprises: abase frame, be U-shaped structure, and comprise for being fixed on sill on electric pole cross-arm, be separately fixed at two lower pillar stands of top, described sill two ends; Transverse axis, is round bar shape, and two ends are set up in respectively on two described lower pillar stands; Cylinder, is cylindric, is sheathed on rotationally on described transverse axis, and is provided with multiple screws along described drum length direction on the surface, both ends of described cylinder; Two side shields, all in the form of annular discs, edge is provided with the through hole radially extending; Set bolt, passes the through hole of described side shield and is screwed in the screw of described cylinder, thereby two described side shields is individually fixed in to the both ends of described cylinder; Seal holder, is inverted U-shaped structure, comprises entablature, is separately fixed at two upper pillar stands of described entablature two ends belows; Two described upper pillar stands are connected respectively with two described lower pillar stands; Hook, is fixed on above the middle part of entablature of described seal holder.
Preferably, at the above-mentioned pulley mechanism for electric power cable unwrapping wire, one of described lower pillar stand is hinged with one of described upper pillar stand, described in another, dock with the lower surface of upper pillar stand described in another upper surface of lower pillar stand, and described in this another, lower outside of upper pillar stand is welded with an outer panel, described outer panel extend downward this another described in the outside of lower pillar stand, and described outer panel is connected by another lower pillar stand of bolt and this.
Preferably, at the above-mentioned pulley mechanism for electric power cable unwrapping wire, described transverse axis is a bolt.
Analyze knownly, of the present utility model adjustable for the trench structure width by cable, can adapt to all types of cables, and can, easily by the joint of cable, can not block line phenomenon.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, the utility model embodiment comprises abase frame 1, transverse axis 431, cylinder 2, side shield 3, set bolt 41, seal holder 6, hook 7.
Particularly, more as shown in Figure 1, abase frame 1 is U-shaped structure, comprises for being fixed on sill (unmarked) on electric pole cross-arm, is separately fixed at two lower pillar stands 11 of top, sill two ends.Sill is provided with through hole, so that be fixed on electric pole cross-arm by the securing member such as bolt, nut.
Transverse axis 431 is round bar shape, and preferably, transverse axis 431 is the bolt that a specification is larger, and its two ends are passed on two lower pillar stands 11 respectively, and spacing by nut 432, prevent that transverse axis 431 from moving left and right.Visible, the present embodiment there is no the comparatively complicated parts of structure such as application bearing.
Cylinder 2 is cylindric, and it is sheathed on transverse axis 431 rotationally, and between two side shields 3.On the surface, both ends of cylinder 2, be provided with multiple screws 21 along drum length direction.According to the specification of conventional electric power cable, can set the distance between adjacent screw 21.Certainly, the spacing of screw 21 might not equate.
Side shield 3 is two, and the two is all in the form of annular discs, and edge is provided with the through hole (not shown) radially extending.Hence one can see that, and the thickness of side shield 3 is larger, and due to the needs of structural strength, also due to the needs of this through hole being set, this through hole can be unthreaded hole on the other hand, can be also screw on the one hand.
The end of thread of set bolt 41, through after the through hole of side shield 3, is screwed in the screw 21 of cylinder 2, thereby two side shields 3 can be individually fixed in to the both ends of cylinder 2.In order to increase the bonding strength between side shield 3, cylinder 2, the through hole at set bolt 41 and corresponding side shield 3 edges should be multiple.
Seal holder 6 is inverted U-shaped structure, comprises entablature (unmarked), is separately fixed at two upper pillar stands 61 of entablature two ends belows; Two upper pillar stands 61 are connected respectively with two lower pillar stands 11.Preferably, one of lower pillar stand 11 is hinged by bearing pin 5 with one of upper pillar stand 61, dock with the lower surface of another upper pillar stand 61 upper surface of another lower pillar stand 11, and the lower outside of this another upper pillar stand 61 is welded with an outer panel 611, outer panel 611 extends downward the outside of this another lower pillar stand 11, and outer panel 611 is connected by another lower pillar stand 11 of bolt 42 and this.
Hook 7 is fixed on the top, middle part of the entablature of seal holder 6.
In the time of application the present embodiment, in the time that electric power cable wire diameter is larger, two side shields 3 can be moved to the end of cylinder 2, with the card line that adapts to the variation of electric power cable wire diameter and avoid joint to cause.In the time that needs are opened seal holder 6, back out bolt 42, along bearing pin 5 rotations, very convenient.
In sum, structure of the present utility model is easy to adjust, and can adapt to the electric power cable of different size, is difficult for occurring card line, the instant card line that occurs, and seal holder is easily opened, and eliminates card line fault.Visible, the utlity model has easy replacing, durable in use, simple in structure, manufacture craft is simple, simple to operate, materials simple, low cost and other advantages.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not depart from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, and is not only.Allly within the scope of the utility model or in the change being equal in scope of the present utility model, be all included in the utility model.
