Problems solved by technology

[0002] The common method of laying cables in pipelines is to pre-string lead wires in the pipeline. However, when the pre-stringed lead wires are pulled out later, the lead wires are often broken, or the pre-stringed lead wires are pulled out by unreasonable people for other purposes. , especially when laying wires indoors, because the indoor walls have been painted and decorated, it is more troublesome, and it is very difficult to re-thread. , not only labor-intensive and time-consuming, but also increase the cost

Embodiment Construction

[0009] exist figure 1 Among them, the wire guide adopts an umbrella structure, and the umbrella structure consists of a head umbrella 1, a tail umbrella 2, a spring 3, a spring upper seat 4, a spring lower seat 5, a pulley 6, a pull cord 7, a screw rod 8, a hollow tube screw 9, Nut 10, viscous piece 11 forms. The head umbrella 1 and the tail umbrella 2 only have ribs 12, the ribs are reeds, the middle part of the reeds is bent into a V shape, at least two ribs are opened at the top, fixed with screw rod 8, and become an umbrella after being fixed. Can expand and shrink, the head diameter of the screw rod 8 of head umbrella is less than the screw rod diameter, and the screw rod head and the screw rod joint are shoulder-shaped, as described, the screw rod head is threaded, equipped with a round head nut cover 13, installed When the screw head passes through the hole on the top of the head umbrella rib, put it on the shoulder of the screw head, tighten and fix it with a nut cove...

Abstract

Provided is a pipeline thread guide, comprising a head umbrella, a tail umbrella, a spring, a pulley and a stay rope. Rib tails of the head umbrella and the tail umbrella are provided with locking pins. In use, the head umbrella and the tail umbrella are plugged into a pipeline, the stay rope is pulled, the head umbrella and the tail umbrella are open in turns, and the locking pins support the inner wall of the pipeline; when the head umbrella supports the inner wall of the pipeline, the tail umbrella is dragged forwards; when the tail umbrella supports the inner wall of the pipeline, under the effect of the spring, the head umbrella is pushed forwards; the stay rope is continuously pulled and loosened, so that the head umbrella and the tail umbrella are continuously pushed forwards until penetrating the whole pipeline.

Description

technical field [0001] The invention relates to a pipeline laying tool, in particular to a threading device for laying cables in pipelines. Background technique [0002] The common method of laying cables in pipelines is to pre-string lead wires in the pipeline. However, when the pre-stringed lead wires are pulled out later, the lead wires are often broken, or the pre-stringed lead wires are pulled out by unreasonable people for other purposes. , especially when laying wires indoors, because the indoor walls have been painted and decorated, it is more troublesome, and it is very difficult to re-thread. , not only time-consuming, but also increase costs. Contents of the invention [0003] In order to facilitate the threading of pipelines, the present invention provides a pipeline lead-in device, which adopts an umbrella structure, and uses the elastic force of the spring to push the umbrella-shaped opening and closing forward to pull the lead wire to complete the threading...
