Abstract

An anti-impact device for pipelines relates to a pipeline protector. The upper part of a fixed ring is a reducing ring (1), an expanding ring (2) is arranged under the reducing ring (1), the bottom of the outer edge of the reducing ring (1) and the top of the expanding ring (2) are formed into a step, and a plurality of bolt holes (3) are arranged at intervals in the expanding ring (2); a steel wire mesh (5) is of an annular structure, and a plurality of steel wire loops (4) which correspond to the bolt holes (3) of the expanding ring (2) are arranged on the top end of the annular steel wire mesh (5); the fixed ring is arranged in the easy-to-wear upper part of a pipeline (6), and after passing through the steel wire loops (4) of the top end of the steel wire mesh (5) and the bolt holes (3) of the expanding ring (2), a plurality of bolts abut against the inner wall of the pipeline (6). The anti-impact device utilizes the transformability of the steel wire mesh to protect a straight pipe, an elbow or an S-shaped pipeline.

Description

A kind of pipeline anti-impact device

[technical field]

The utility model relates to a kind of pipeline protection device, especially relates to a kind of pipeline anti-impact device.

[background technique]

Known, when processing mine tailing, need to utilize pipeline to carry broken ore, impact due to broken ore, make abrasion of conveying pipes very fast, particularly the elbow of pipeline and the wearing and tearing of many places pipeline junction are very serious, and these local pipelines replacing difficulty are very large, the effort of taking a lot of work, also needs parking maintenance.

[summary of the invention]

In order to overcome the deficiency in background technique, the utility model discloses a kind of pipeline anti-impact device, the utility model utilizes the deformable characteristic of steel wire, can realize the protection of straight tube, bend pipe or serpentine pipeline.

For achieving the above object, the utility model adopts following technological scheme:

An anti-impact device, comprises pipeline, retaining ring and steel wire, and the top of retaining ring is necking down ring, in necking down ring bottom, is provided with hole enlargement ring, and described necking down ring outer rim bottom and hole enlargement Huan upper end form step, are interval with a plurality of screws on hole enlargement ring; Steel wire is loop configuration, is provided with the steel wire cover of a plurality of corresponding hole enlargement ring screws in the upper end of loop configuration steel wire; Retaining ring is arranged on pipeline top easy to wear, by a plurality of bolts, is withstood on inner-walls of duct after through the steel wire cover of steel wire upper end, screw on hole enlargement ring.

Described pipeline anti-impact device forms broken ore and piles up gap between the necking down ring of hole enlargement ring upper end and inner-walls of duct.

Described pipeline anti-impact device, the described bolt on hole enlargement ring is hidden in the inner face lower end of necking down ring.

Owing to having adopted technique scheme, the utlity model has following beneficial effect:

Pipeline anti-impact device described in the utility model; utilize necking down ring and the inner-walls of duct gap of hole enlargement ring upper end to retain a small amount of broken ore; by broken ore, formed the protection of retaining ring; steel wire forms the protection of pipeline; the utility model is simple in structure; be convenient to install, especially steel wire deformable can adapt to the protection of complicated pipeline.

[accompanying drawing explanation]

Fig. 1 is structural representation of the present utility model;

Fig. 2 is that the utility model is at ducted structural representation;

In figure: 1, necking down ring; 2, hole enlargement ring; 3, screw; 4, steel wire cover; 5, steel wire; 6, pipeline; 7, gap.

[embodiment]

By the following examples, can explain in more detail the utility model, the utility model is not limited to the following examples, and open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model;

Pipeline anti-impact device described in 1 or 2 by reference to the accompanying drawings, comprise pipeline 6, retaining ring and steel wire 5, the top of retaining ring is necking down ring 1, in necking down ring 1 bottom, be provided with hole enlargement ring 2, the upper end of described necking down ring 1 outer rim bottom and hole enlargement ring 2 forms step, between the necking down ring 1 on step top and pipeline 6 inwalls, form broken ore and pile up gap 7, on hole enlargement ring 2, be interval with a plurality of screws 3; Steel wire 5 is loop configuration, is provided with the steel wire cover 4 of a plurality of corresponding hole enlargement ring 2 screws 3 in the upper end of loop configuration steel wire 5; Retaining ring is arranged on pipeline 6 top easy to wear, by a plurality of bolts, is withstood on pipeline 6 inwalls after through the steel wire cover 4 of steel wire 5 upper ends, screw 3 on hole enlargement ring 2, and the described bolt on hole enlargement ring 2 is hidden in the inner face lower end of necking down ring 1.

Implement pipeline anti-impact device described in the utility model, be applicable to the pipeline use that large-scale pipeline or diameter are greater than 50 centimeters; During use, retaining ring is sent into pipeline 6 correct positions, utilized bolt that the hole enlargement ring 2 of retaining ring is fixed on the inwall of pipeline 6, wherein the end that screws at bolt rear portion is hidden in necking down ring 1 bottom; After start, utilize the necking down ring 1 of hole enlargement ring 2 upper ends to retain a small amount of broken ore with pipeline 6 inwall gaps 7; by broken ore, form the protection to retaining ring; deformable due to steel wire 5; by steel wire 5, formed the protection of pipeline 6 straight tubes, bend pipe or serpentine pipeline; the utility model is simple in structure; be convenient to install, especially steel wire deformable can adapt to the protection of complicated pipeline.

The utility model does not describe part in detail for prior art.
