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 In the middle, only the first rib 3 is set between the head umbrella 1 and the tail umbrella 2. The first rib adopts a reed, and the middle part of the reed is bent into a V shape. At least two second ribs have holes at the top of the V shape. , fixed with screw 4, after fixing, it becomes an umbrella shape, which can be expanded and contracted. The diameter of the screw head of the head umbrella is smaller than the diameter of the screw. Head nut cover 5. When installing, the screw head passes through the hole at the top of the second umbrella rib of the head umbrella, rests on the shoulder of the screw head, tightens and fixes it with the nut cover, and after tightening, the nut cover is placed on the umbrella tip of the head umbrella , the screw rear part 6 is in the umbrella, the rear screw end is connected to the spring upper seat 7, the upper part of the spring 8 is fixed below the spring upper seat, and the pulley 9 is fixed at the center of the sp...

Abstract

The invention discloses a pipeline guy machine. The pipeline guy machine is of an umbrella-shaped structure. The umbrella-shaped structure is composed of a head umbrella, a tail umbrella, an electric telescopic rod, springs, a controller and an umbrella closing rope. The tail of umbrella ribs of the head umbrella and the tail of umbrella ribs of the tail umbrella are provided with retaining feet. During usage, the head umbrella and the tail umbrella are inserted into a pipeline, the head umbrella and the tail umbrella are unfolded in turn through the telescopic rod and the springs, and the inner wall of the pipeline is supported by the retaining feet; when the inner wall of the pipeline is supported by the head umbrella, the tail umbrella is dragged forwards; when the inner wall of the pipeline is supported by the tail umbrella, the head umbrella is pushed forwards under the action of the springs and extends and retracts constantly, and the head umbrella and the tail umbrella are pushed forwards constantly until the head umbrella and the tail umbrella pass through 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 cable pulling machine for pipelines. The cable pulling machine adopts an umbrella structure, and uses the elastic force of the spring to push the opening and closing of the umbrella forward to pull the lea...
