Abstract
The utility model discloses a high-voltage cable drawing head. The high-voltage cable drawing head comprises a taper protecting tube (6), a collapsible tube (5) and a pressed master drawing head (1), an inner hole of the taper protecting tube (6) is a cone hole, an outer surface of the collapsible tube (5) is a cone surface, and the tapering of the outer surface of the collapsible tube (5) is matched with that of the inner hole of the taper protecting tube (6). An internal thread section (4) is processed at the end of the inner hole of the taper protecting tube (6), the diameter of the end of the inner hole of the taper protecting tube (6) is bigger, the pressed master drawing head (1) is a cone head, an external thread section (3) is processed at the bottom of the cone head, the external thread section (3) of the pressed master drawing head (1) is matched with a thread of the internal thread section (4) of the tapering protecting tube (6), the maximum diameter of the pressed master drawing head (1) is equal to that of the taper protecting tube (6), and a drawing rope hole (2) is processed at the end portion of the pressed master drawing head (1). A cable is drawn by the high-voltage cable drawing head, and the cable is capable of ensuring that skin is not damaged through a pipeline. Meanwhile, the cable is time-saving and labor-saving when passing through the pipeline because a cable head is moisture-resistant and water-resistant.
Description
Technical field
The utility model relates to a kind of Threading tool, especially a kind of high-tension cable drawing head.
Background technology
Power cable is used for transmission and distributes electric energy, compares with overhead transmission line, and its advantage is: it is little influenced by extraneous factor, and power supply reliability is high.2, power cable is buried, and engineering is hidden, and is less to city appearance environment influence, even if having an accident, generally also can not influence personal safety .3, cable capacitance is bigger, can change the power factor of circuit.
At present, utilizing trenchless technology to lay penetration pipe comes cable laying very general.Cable directly being pierced into very difficulty of penetration pipe, therefore, design a kind of high-tension cable drawing head of cable laying, is the present technical issues that need to address.
Summary of the invention
The utility model technical problem to be solved provides a kind of high-tension cable drawing head.
The technical scheme that the utility model solves its technical problem is:
The high-tension cable drawing head, by tapering protection tube, collapsible tube with compress female drawing head and form, it is characterized in that: the endoporus of tapering protection tube is a taper hole; The outer surface of collapsible tube also is the conical surface; The tapering of the tapering of collapsible tube outer surface and tapering protection tube endoporus coupling is processed with internal thread segment at the bigger end of diameter of bore of tapering protection tube, and compressing female drawing head is nose cone; Be processed with external thread section in cone headed awl bottom; Compress the screw thread coupling of internal thread segment of external thread section and the tapering protection tube of female drawing head, the maximum gauge that compresses female drawing head is identical with the external diameter of tapering protection tube, is processed with the pull rope hole in the end that compresses female drawing head.During use; At first the diameter of bore of cable from the tapering protection tube pierced in the tapering protection tube than small end; Again collapsible tube is put in the tapering protection tube and made it encase cable end from the bigger end of diameter of bore of tapering protection tube, will compress then in female drawing head precession tapering protection tube and make the collapsible tube clamping cables, fix steel wire rope in the pull rope hole and steel wire rope from penetration pipe is advanced at last; Pass from the other end, haulage cable can pierce into cable in the penetration pipe.
Preferably, the tapering of the outer surface of the tapering of the endoporus of tapering protection tube and collapsible tube is 1.768.
The screw thread of the screw thread of the external thread section of the cone headed awl bottom processing of the utility model and the internal thread segment of tapering protection tube is all cylindrical thread or taper thread.
The material of making collapsible tube is nylon or spring steel.
The beneficial effect of the utility model:
Utilize high-tension cable drawing head trailing cable, cable has guaranteed that crust is not damaged, cable end moistureproof, has not intake through pipeline, and cable is time saving and energy saving through pipeline.
