Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline structures, and particularly relates to a high-stability pumping pipeline for mines. Background Technique

[0002] Compared with the existing common fixed pipelines, the biggest feature of the pumping pipeline is its temporary usability, that is, the pumping pipeline needs to be erected before pumping and removed after the pumping operation is completed.

[0003] Therefore, in terms of structure, the single pipes of the pumping pipeline generally adopt movable connection methods such as screw connection, while the above-mentioned fixed pipelines generally adopt methods such as strong plug-in connection, and the latter is relatively difficult to pull out and disassemble.

[0004] On the other hand, compared with the pumping pipelines used in ordinary road construction, the pumping pipelines used in mines have a more severe use scenario, which requires the pumping pipelines used in mines to have a relatively more stable connection structure to ensure that the above-mentioned connection structure is not easily disassembled when the pumping pipelines in mines are rolled, pulled, and impacted.

[0005] For example, the Chinese utility model patent with the authorization announcement number CN212226294U and the authorization announcement date of December 25, 2020 discloses a pipeline connection structure for a water pump in a water conservancy project, which includes two connecting pipelines. The opposite ends of the two connecting pipelines are in contact with each other. A connecting piece that is snap-connected to it is sleeved on each of the two connecting pipelines. Uniformly distributed limiting chutes are opened on the sides of the two connecting pieces close to each other. Contact rings are integrally formed on each of the two connecting pieces. The limiting chutes are respectively located on the sides of the two connecting pieces away from each other. Moving rings are sleeved on each of the two connecting pieces. Uniformly distributed sliding limiting teeth are integrally formed on the inner sides of the two moving rings. The two moving rings are slidably connected to the two connecting pieces respectively through the sliding limiting teeth and the limiting chutes.

[0006] The pipeline connection structure in this utility model patent has the following general advantages: it is convenient for users to connect and use the pipeline for the water pump, the operation is simple and convenient, the structure is firm and stable, and the possibility of liquid leakage can be reduced during use.

[0007] However, during the actual use process of this pipeline connection structure, there are at least the following two deficiencies, which are also the technical problems to be solved by the present utility model, that is:

[0008] First, in addition to the pipe body itself, this structure also includes multiple independent parts, such as at least including 2 contact rings, 2 moving rings and 1 threaded sleeve, which is relatively complex and not conducive to the rapid installation of the pipeline;

[0009] Second, its threaded sleeve is directly exposed as a direct connection structure. Therefore, when the pipeline is pulled or bumped, the threaded sleeve is prone to displacement and deformation, ultimately resulting in incomplete sealing at the connection and easy water leakage at this place.

[0010] Therefore, in summary, there is an urgent need for a splicing pipeline with relatively simple connection operations and sufficient stability at the connection part for use in mine pumping operations. Utility Model Content

[0011] The present utility model provides a high-stability pumping pipeline for mines, which can make the following through the way of setting a fixed ring, an opening ring, a screw connection unit, a sealing ring unit, a protective sleeve unit, and a sealing ring unit on the pipe body: 1. The connection structure of the pumping pipeline is relatively simple, with only the sealing ring unit as an independent part, and the connection operation is simple and convenient; 2. The outside of the connection structure is covered and protected by the protective sleeve unit and the sealing ring unit, making it not easy to disassemble and having good stability, even when the pumping pipeline is pulled, rolled, or impacted.

[0012] The technical solution adopted by the present utility model to solve the above problems is: a high-stability pumping pipeline for mines, the structure includes a pipe body, and also includes a fixed ring and an opening ring respectively arranged on the respective connection end faces of two adjacent pipe bodies, a screw connection unit arranged on the fixed ring and inserted into the opening ring, a sealing ring unit arranged between the fixed ring and the opening ring and sleeved on the screw connection unit, a protective sleeve unit arranged on the fixed ring and sleeved on the opening ring and used to cover the screw connection unit, and a sealing ring unit arranged on the same pipe body as the opening ring and used to dock with the protective sleeve unit.

[0013] A further preferred technical solution lies in: the screw connection unit includes a screw arranged on the fixed ring and inserted into the opening ring, and a nut arranged on the screw and used to clamp the opening ring.

[0032] The following is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.

[0033] As shown in the attached Figures 1-6 As shown, a high-stability pumping pipeline for a mine, the structure includes a pipe body 11, and also includes a fixed ring 1 and a perforated ring 2 respectively arranged on the respective connection end faces of two adjacent pipe bodies 11, a screw connection unit 3 arranged on the fixed ring 1 and inserted into the perforated ring 2, a sealing ring unit 4 arranged between the fixed ring 1 and the perforated ring 2 and sleeved on the screw connection unit 3, a protective sleeve unit 5 arranged on the fixed ring 1 and sleeved on the perforated ring 2 and used to cover the screw connection unit 3, and a sealing ring unit 6 arranged on the same pipe body 11 as the perforated ring 2 and used to dock with the protective sleeve unit 5.

[0034] In this embodiment, the material of the pipe body 11 can be metal or hard plastic. Specifically, for example, it is a PVC steel wire pipe, so as to provide appropriate bending ability in the length direction and sufficient supporting ability in the radial direction.

[0035] Among them, the fixed ring 1 and the perforated ring 2 are integrally formed with their respective corresponding pipe bodies 11. In addition, the fixed ring 1, the screw connection unit 3 and the protective sleeve unit 5 are also integrally formed, and the sealing ring unit 6 is integrally formed with the other pipe body 11.

[0036] Therefore, only the sealing ring unit 4 in this pumping pipeline is a separate part, so this pumping pipeline has the advantages of relatively simple structure and convenient disassembly and assembly.

[0037] In addition, the protective sleeve unit 5 is not a direct connection structure, and its functions are:

[0038] First, when the screw connection unit 3 is disassembled and assembled, its own length shrinks, so as to expose and provide sufficient space required for disassembly and assembly operations;

[0039] Second, after the screw connection unit 3 is disassembled and assembled, when this pumping pipeline is in normal use, its own length elongates and then abuts against the sealing ring unit 6, finally covering the screw connection unit 3. At this time, even if this pumping pipeline is pulled, impacted, or twisted, this connection structure is not easy to come apart, and finally an efficient pumping effect of relatively not easy to leak water is achieved.

[0040] The screw connection unit 3 includes a screw 301 disposed on the fixed ring 1 and inserted into the perforated ring 2, and a nut 302 disposed on the screw 301 and used to clamp the perforated ring 2.

[0041] In this embodiment, the openings on the perforated ring 2 are located on the relatively outer side in the radial direction, are circular in shape, and their quantity and distribution mode correspond to the screw 301.

[0042] On the other hand, the screw 301 is perpendicular to the fixed ring 1. When the screw connection unit 3 is installed, the screw 301 needs to first pass through the openings on the perforated ring 2, and then the nut 302 is tightened. At this time, the nut 302 can fully and appropriately press the sealing ring unit 4, thereby providing sufficient pipeline sealing and leakage prevention effect.

[0043] The sealing ring unit 4 includes a circular sealing ring 401 disposed between the fixed ring 1 and the perforated ring 2, and an opening block 402 disposed on the outer ring surface of the circular sealing ring 401 and sleeved on the screw 301.

[0044] In this embodiment, the circular sealing ring 401 and the opening block 402 are integrally formed, and the material is ordinary rubber. The former functions to fully fit the fixed ring 1 and the perforated ring 2, so that the only possible leakage position in the pumping pipeline has sufficient sealing effect.

[0045] In addition, the first function of the opening block 402 is to prevent the circular sealing ring 401 from sliding and shifting. Although the above-mentioned shifting phenomenon generally hardly causes leakage problems, after the circular sealing ring 401 and the pipe body 11 are misaligned, the former may slightly block the water body, thereby reducing the pumping efficiency of the pipeline.

[0046] The second function of the opening block 402 is reflected in the reuse of the circular sealing ring 401. It can prevent the circular sealing ring 401 from rotating unnecessarily during secondary use.

[0047] Because for the butting sides of the fixed ring 1 and the perforated ring 2, it is impossible to be completely flat. Therefore, when the circular sealing ring 401 is used for the first time, it has formed a specifically and fully fitting "convex-concave shape" according to the slight "concave-convex shape" of the above-mentioned butting sides. If the circular sealing ring 401 rotates during secondary use, the original high-degree fitting effect disappears, which is not conducive to the pipeline sealing performance.

[0048] The protective sleeve unit 5 includes a fixed tube 501 whose inner ring surface is arranged on the outer ring surface of the fixed ring 1 and is used to sleeve the open hole ring 2, and an outer tube 502 which is screwed on the outer ring surface of the fixed tube 501 and is used to disassemble and assemble the screw connection unit 3 by rotating away from the sealing ring unit 6.

[0049] In this embodiment, the fixing ring 1 and the fixing tube 501 are integrally formed, and when the sealing ring unit 4 is fully clamped, the spacing distance between the fixing tube 501 and the sealing ring unit 6 is sufficient to disassemble and assemble the nut 302 .

[0050] After the nut 302 is installed, the outer tube 502 rotates toward the sealing ring unit 6 to fully cover the most direct and critical connection part of the screw connection unit 3, thereby ensuring that the connection structure is not easy to disintegrate.

[0051] On the other hand, during normal use, the pipeline will inevitably be twisted, hit, pulled, etc. At this time, the outer tube 502 may rotate spontaneously and detach from the sealing ring unit 6. This is unavoidable and of course will not directly affect the connection stability of the pumping pipeline. This unexpected phenomenon can only be solved by regular manual inspection.

[0052] The sealing ring unit 6 includes an end ring 601 which is arranged on the outer ring surface of the tube body 11 and is used to clamp the outer tube 502 .

[0053] In this embodiment, the end ring 601 and the tube body 11 are relatively perpendicular, and the outer diameter of the former is slightly larger than the outer diameter of the outer tube 502, so that the fixed ring 1, the fixed tube 501, the outer tube 502 and the end ring 601 together can cover and protect the core screw connection unit 3 and the sealing ring unit 4 in the connection structure to prevent the connection structure from spontaneously disintegrating.

[0054] The number of the screw connection units 3 is 2-3, and two nuts 302 are disposed on a single screw rod 301 .

[0055] In this embodiment, 2-3 screw connection units 3 are evenly spaced in the ring direction, and two nuts 302 are stacked to more firmly press the perforated circular ring 2.

[0056] Annular grooves 7 for engaging the circular sealing ring 401 are provided on the opposite sides of the fixed circular ring 1 and the perforated circular ring 2 .

[0057] In this embodiment, one of the functions of the annular groove 7 is to enable the circular sealing ring 401 and the pipe body 11 to be simply and accurately aligned. Otherwise, after the installation position of the former is skewed, it is easy to block the water body and reduce the pumping efficiency.

[0058] And the second function of the annular groove 7 is to provide a longer, more tortuous and less leaky docking seam in the radial direction, further improving the sealing performance of the circular sealing ring 401.

[0059] Wherein, the width of the annular groove 7 is equal to the radial thickness of the circular sealing ring 401, and its depth is 1.0 - 1.5 cm.

[0060] The outer diameter of the fixed ring 1 is greater than the outer diameter of the perforated ring 2.

[0061] In this embodiment, the perforated ring 2 cannot affect the sleeving action of the fixed pipe 501 on it, and at the same time, it is necessary to provide appropriate and beneficial support inside the fixed pipe 501.

[0062] Therefore, the above-mentioned outer diameter difference is set to 1 - 2 cm, which can ensure that the above two functions are reasonably balanced.

[0063] The sealing ring unit 6 further includes a suspension opening 602 provided on the end ring 601.

[0064] In this embodiment, during the normal use of the pumping pipeline, the pipeline can be appropriately lifted as needed by bundling and suspending or inserting a rod at the suspension opening 602, so that it can stably cross the ground obstacles.

[0065] When the pipeline is being stored for later use, the suspension opening 602 can also be used as a threading position for connecting and stringing up and collecting the pipe body 11.

[0066] The sealing ring unit 6 further includes a connecting rope 603 provided on the suspension opening 602, and a well wall inserting rod 604 provided on the connecting rope 603.

[0067] In this embodiment, when the well wall inserting rod 604 is inserted into the well wall, the pipeline can be appropriately suspended and fixed. Otherwise, the weight of the vertical section of the pipeline is all applied to the screw connection unit 3, which is not conducive to the stability of the connection structure.

[0068] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the gist of the present invention. These are all non-creative modifications and are protected by the Patent Law as long as they are within the scope of the claims of the present invention.
