Abstract
The utility model provides a connector for sleeving and dragging a PE (Polyethylene) pipeline. The connector comprises a traction handle with a traction hole, a traction rod, a conical cover, a conical barrel and three arc-shaped iron sheets assuming angles being 120 degrees with each other, wherein the traction handle is arranged at the upper end of the traction rod, and the conical barrel is arranged at the lower end of the traction rod; the conical cover is arranged above the conical barrel, is sleeved on the traction rod, and is provided with a mounting groove integrated with the conical cover; the mounting groove is provided with the arc-shaped iron sheets and is positioned on the outer side of the conical barrel; the thickness each arc-shaped iron sheet close to one end of the conical cover is larger than that of the other end; pulling holes are formed in the middles of the arc-shaped iron sheets; the outer surface of each arc-shaped iron sheet is provided with a screw thread; the length of each arc-shaped iron sheet is larger than that of the conical barrel; three limiting posts are uniformly arranged on the outer wall of the conical barrel, and are positioned in the pulling holes. The connector has the beneficial effects of simple structure, firmness in sleeving, convenience in use, saving of time and force, and the like.
Description
Technical field
The utility model belongs to non-excavation crossing construction field, especially relates to a kind of being locked back and drags the connector of PE pipeline.
Background technology
In existing technology, non-excavation passes through engineering conventionally need to be separated with PE pipeline by drilling rod, in PE pipeline returning process, by connector and drilling rod socket, returns and drag.Exist connector socket insecure, easily come off, waste time and energy, the problems such as inefficiency.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, be socketed the connector that PE pipeline is dragged in firm, easy to use, time saving and energy saving being locked back, be especially applicable to non-excavation and pass through engineering.
The technical solution of the utility model is: a kind of being locked back dragged the connector of PE pipeline, comprise the traction handle with towing pad, draw bar, cone-shaped hood, conically shaped and three arc iron plates that are mutually 120 degree angles, described draw bar upper end is provided with traction handle, lower end is provided with conically shaped, described conically shaped top is provided with cone-shaped hood, this cone-shaped hood is sleeved on draw bar, described cone-shaped hood is provided with the mounting groove being integrated with it, described mounting groove is provided with arc iron plate and is positioned at conically shaped outside, described arc iron plate is greater than the thickness of the other end near the thickness of one end of cone-shaped hood, described arc iron plate middle part is provided with pulling eye, external surface is provided with screw thread, the length of this arc iron plate is greater than the length of conically shaped, on described conically shaped outer wall, be evenly provided with 3 limited posts and be arranged in pulling eye.
Further, described draw bar middle and lower part is provided with screw thread.
Further, described draw bar is connected with cone-shaped hood, conically shaped by screw thread.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, three of the Intermediate Gray pulling eye arc iron plates that are mutually 120 degree angles are enclosed within to drilling rod one end, when drilling rod is outside stressed, the limited post of the fixed hole position of the cone-shaped hood of upper end and drilling rod inner side, make three arc iron plates drilling rod that is more locked, stressed larger, contact more firmly with drilling rod, prevent that drilling rod from coming off returning in dragging process; Have simple in structure, socket firmly, the advantage such as easy to use, time saving and energy saving.

The specific embodiment
As Figure 1-3, the technical solution of the utility model is: a kind of being locked back dragged the connector of PE pipeline, comprise the traction handle 2 with towing pad 1, draw bar 3, cone-shaped hood 4, conically shaped 5 and three arc iron plates 6 that are mutually 120 degree angles, described draw bar 3 upper ends are provided with traction handle 2, lower end is provided with conically shaped 5, described conically shaped 5 tops are provided with cone-shaped hood 4, this cone-shaped hood 4 is sleeved on draw bar 3, described cone-shaped hood 4 is provided with the mounting groove 7 being integrated with it, described mounting groove 7 is provided with arc iron plate 6 and is positioned at conically shaped 5 outsides, described arc iron plate 6 is greater than the thickness of the other end near the thickness of one end of cone-shaped hood 4, described arc iron plate 6 middle parts are provided with pulling eye 8, external surface is provided with screw thread, the length of this arc iron plate 6 is greater than the length of conically shaped 5, on described conically shaped 5 outer walls, be evenly provided with 3 limited posts 9 and be arranged in pulling eye 8.
In the present embodiment, described draw bar 3 middle and lower parts are provided with screw thread, and described draw bar 3 is connected with cone-shaped hood 4, conically shaped 5 by screw thread.
The course of work of this example: during work, by steel wire penetrating towing pad 1, the other end hangs over back and drags on equipment; Three of the Intermediate Gray pulling eye 8 arc iron plates 6 that are mutually 120 degree angles are enclosed within to drilling rod one end, drilling rod is outside when stressed, and the limited post 9 of the fixed hole position of the cone-shaped hood 4 of upper end and drilling rod inner side makes three arc iron plates 6 drilling rod that is more locked, stressed larger, contact more firm with drilling rod; The outer surface cover being connected with drilling rod at connector has outer sleeve, prevents from rising in dilatory process sudden and violent.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
