Description

Cable drawing head
Technical field
The utility model relates to cable traction device, refers more particularly to a kind of electric traction head protecting cable.
Background technology
In recent years, along with electricity market is to the increase of power demand, city net, increasing of upgrading of rural power grids engineering, electricity capacity constantly increases, for raising urban electricity supply safety, beautify the object of the needs of the appearance of the city, the power circuit erection of present most cities progressively turns to from overhead transmission line development of putting cable underground, wherein relate to polytypic, large batch of cable laying work, because the work of laying of the power cable of majority is all in ditch, carry out in pipe, and in the process of cable laying, the traction of cable should be noted that safety, fast, the factor of the aspect such as efficient, at present, in the distraction procedure of cable construction, general employing is at the simple and easy colligation steel cable of cable sheath or adopt metal crimp adapter to compress cable end, there is very many-sided problem in such drawing head, 1, adopt colligation steel cable, because colligation is that artificial colligation easily gets loose, under powerful tractive effort effect, steel cable easily slip away cable pulling binding point, and in the process of mechanical device trailing cable, hauling speed is very fast, the colligation of steel cable not only can the insulation top layer of badly damaged cable, even the inner core of cable can be destroyed, 2, adopt metal crimp adapter drawing head may need to complete in factory, due to aluminium hydraulic pressed connecting pipe crimping after be out of shape, can not reuse, belong to easy consumption product, inefficiency and use time not too convenient.
Utility model content
For the problem in above-mentioned prior art existing for cable drawing head, the utility model provides a kind of reasonable in design, easy to operate, reusable, cable drawing head of being suitable for different model cable.
The technical scheme that the technical problems to be solved in the utility model is taked is: it comprises some claws, gear adjusting nut, axle sleeve, link and connecting rod, one end socket gear adjusting nut of described axle sleeve, described claw distributes in the form of a ring and tilting action is arranged in axle sleeve and gear adjusting nut, claw runs through axle sleeve and is meshed with gear adjusting nut, claw and the contact-making surface of cable are two oblique crossing side contacts faces, one end of described connecting rod is connected with axle sleeve through gear adjusting nut, the other end is connected with link, the middle part of described connecting rod is fixed with rear shelves, described rear shelves conically.
Further, the contact-making surface of described claw and cable is provided with groove.
The beneficial effects of the utility model: compared to prior art, the utility model has the following advantages, and 1, structure is simple, low cost of manufacture, can Reusability; 2, different cross-section of cable sizes can be suitable for; 3, be convenient to stube cable and cable wire of pulling strings, can be used for mechanical traction; 4, remove and install conveniently.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model,
Fig. 2 is the plan structure schematic diagram of the utility model with part section,
Fig. 3 is the left TV structure schematic diagram of utility model.
In the drawings, 1, claw 2, gear adjusting nut 3, axle sleeve 4, rear shelves 5, link 6, cable 7, wheel spanner counterbore 8, connecting rod 9, protective cover 10, groove 11, side contacts face.
Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, in conjunction with embodiment, the utility model is described in further detail with reference to the accompanying drawings below.
As Fig. 1, 2, shown in 3, cable drawing head, comprising in some claw 1(figure is three, suitably can adjust according to cable inner core), gear adjusting nut 2, axle sleeve 3, link 5 and connecting rod 8, one end socket gear adjusting nut (gear adjusting nut is bevel gear adjusting nut) of described axle sleeve, axle sleeve leaves wheel spanner counterbore 7(umbrella shape, wheel spanner transmitting gear adjusting nut easy to use), claw described in the present embodiment is that three inclination uniform intervals are arranged (left low right height), claw is provided with tooth bar, axle sleeve is provided with slotted eye, claw activity runs through axle sleeve (namely claw can move in the slotted eye in axle sleeve), claw external part and conductive cable contacts face are two crossing side contacts faces 11, relative both sides contact-making surface clamps a cable, claw and gear adjusting nut are matched by tooth, when transmitting gear adjusting nut, claw can synchronously be moved to the left, utilize side contacts face and the conductive cable contacts of claw, from but the cable 6 between claw can be clamped mutually, claw and the contact-making surface of cable are two oblique crossing side contacts faces, it is threaded engagement between described claw and gear adjusting nut, one end connecting bushing of described connecting rod (is connected by screw thread or bolt, then cover has protective cover 9), the other end connects link, link is for connecting the cable wire of mechanical draw-gear, rear shelves 4 are fixed with in the middle part of connecting rod, described rear shelves conically, rear shelves are used for pushing earth outstanding for ground or stone to both sides in traction process.
Further, described axle sleeve, rear shelves, connecting rod also can be formed in one.The contact-making surface of claw and cable 6 is provided with groove 10, can the inner core of attached cable further.
In use, by the insulating barrier peeling of an end head of cable, three inner cores are inserted respectively between the annular claw arranged, rotate by hand or use umbellate form wheel spanner to snap in wheel spanner counterbore 7 and driven gear adjusting nut, and regulated the folding scope of claw according to the different model of cable by gear adjusting nut, inner core is fixed on drawing head by the groove of the contact-making surface of claw and cable inner core further, and the cable wire of solid mechanical draw-gear on link, thus reach the object of the traction of cable in cable tube, so not only little to the damage of cable, and it is simple to operation, through field test, cable drawing head compared to existing technology saves a lot of time.
Above execution mode is only in order to illustrate the technical solution of the utility model and unrestricted; although be described in detail the utility model with reference to specific embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement; and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the scope of claim of the present utility model protection.
