Abstract
The invention relates to a pipeline protective device, particularly to a pipeline shock resistance device, wherein a necking ring (1) is arranged at the upper part of a fixing ring, an expanding ring (2) is arranged at the lower part of the necking ring (1), a step is formed between the lower part of the outer edge of the necking ring (1) and the upper end of the expanding ring (2), a plurality of screw holes (3) are formed at intervals in the expanding ring (2), a steel wire mesh (5) is of an annular structure, a plurality of steel wire sleeves (4) corresponding to the screw holes (3) in the expanding ring (2) are arranged at the upper end of the annular steel wire mesh (5), the fixing ring is arranged at the upper part which is easily worn of a pipeline (6) and propped against the inner wall of the pipeline (6) through a plurality of bolts penetrating through the steel wire sleeves (4) at the upper end of the steel wire mesh (5) and the screw holes (3) in the expanding ring (2). The pipeline shock resistance device can realize protection of a straight pipe, a bent pipe or an S-shaped pipeline by utilizing the deformation characteristic of the steel wire mesh.
Description
[technical field]
The present invention relates to a kind of pipeline protection device, especially relate 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 wearing and tearing of the elbow of pipeline and 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 invention discloses a kind of pipeline anti-impact device, the present invention 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 present invention adopts following technological scheme:
A kind of pipeline anti-impact device comprises pipeline, retaining ring and steel wire, and the top of retaining ring is the necking down ring, is provided with the hole enlargement ring in necking down ring bottom, and the upper end of described necking down ring outer rim bottom and hole enlargement ring forms step, is interval with a plurality of screws on the 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, withstands on inner-walls of duct after passing the steel wire cover of steel wire upper end, screw on the hole enlargement ring by a plurality of bolts.
Described pipeline anti-impact device forms broken ore and piles up the 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 the hole enlargement ring is hidden in the inner face lower end of necking down ring.
Owing to having adopted technique scheme, the present invention has following beneficial effect:
Pipeline anti-impact device of the present invention; 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; formed the protection of retaining ring by broken ore; steel wire forms the protection of pipeline; the present invention is simple in structure; be convenient to install, especially the steel wire deformable can adapt to the protection of complicated pipeline.
[description of drawings]
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the present invention 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]
Can explain in more detail the present invention by the following examples, the present invention is not limited to the following examples, discloses purpose of the present invention and is intended to protect all changes and improvements in the scope of the invention;
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, be provided with hole enlargement ring 2 in necking down ring 1 bottom, the upper end of described necking down ring 1 outer rim bottom and hole enlargement ring 2 forms step, form broken ore and pile up gap 7 between the necking down ring 1 on step top and pipeline 6 inwalls, be interval with a plurality of screws 3 on hole enlargement ring 2; 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, withstands on pipeline 6 inwalls after passing the steel wire cover 4 of steel wire 5 upper ends, screw 3 on hole enlargement ring 2 by a plurality of bolts, 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 of the present invention, be applicable to large-scale pipeline or diameter and use greater than the pipeline of 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; The necking down ring 1 that utilizes hole enlargement ring 2 upper ends after start and pipeline 6 inwall gaps 7 retain a small amount of broken ore; form protection to retaining ring by broken ore; deformable due to steel wire 5; formed the protection of pipeline 6 straight tubes, bend pipe or serpentine pipeline by steel wire 5; the present invention is simple in structure; be convenient to install, especially the steel wire deformable can adapt to the protection of complicated pipeline.
Part not in the detailed description of the invention is prior art.
