Abstract
The utility model discloses a hydraulic reclamation pipeline with a self-locking flange structure, which comprises a pipe body and flanges at two ends of the pipe body, wherein the flanges are provided with flange holes; the counter bore section is positioned on the side of the pipe body, and the counter bore section is in a hexagon socket structure; the flange hole of the flange at the other end of the pipe body is a through hole. Compared with the prior art, the method has the advantages that the labor, tools and time for installing and dismantling the pipeline are effectively reduced, and the working efficiency is improved; the utility model has the advantages of simple structure, convenient and easy use, high repeated utilization degree and the like.
Description
Technical Field
The utility model belongs to the technical field of hydraulic reclamation engineering, and particularly relates to a hydraulic reclamation pipeline with a self-locking flange structure.
Background
Pipeline often installs and tears open and move because of the engineering needs in the hydraulic reclamation work progress, when the pipeline was used in the past, generally adopted alone fixed spiral shell head, another people adopts spanner or wind big gun installation or dismantles the nut to need install or demolish the operation piece by piece, work load is big, and the repeatability is high, and manpower resources occupies manyly.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the utility model provides a hydraulic filling pipeline with a self-locking flange structure, which reduces the labor, tools and time for installing and removing the pipeline,
the hydraulic reclamation pipeline with the self-locking flange structure is characterized in that the flange hole on the flange at one end of the pipe body comprises a smooth hole section and a counter bore section, the smooth hole section is positioned on the splicing surface side of the flange, and the through hole is circular; the counter bore section is positioned on the side of the pipe body, and the counter bore section is in a hexagon socket structure; the flange hole of the flange at the other end of the pipe body is a through hole.
Preferably, the counter bore section is a second-order counter bore.
The utility model has the advantages and positive effects that:
as the pipeline mounting and dismounting operation adopts the brand-new technical scheme, compared with the prior art, the utility model effectively reduces the labor, tools and time for mounting and dismounting the pipeline and improves the operation efficiency; the utility model has the advantages of simple structure, convenient and easy use, high repeated utilization degree and the like.
Drawings
FIG. 1 is a schematic structural view of example 1 of the present invention;
fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.
In the figure, 1, a tube body; 2. a flange; 2-1, flange holes; 2-10, a unthreaded hole section; 2-11 and a counter bore section.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
In embodiment 2, referring to fig. 2, preferably, the counter bore section is a second-order counter bore, and is suitable for the sizes of bolt caps of two different flange bolts, so that the bolt adaptation range of the pipeline is expanded. The rest of the structure was the same as in example 1.
The flange with the hexagon socket type counter bore section can restrict the bolt from freely rotating after the bolt is inserted into the bolt hole, thereby replacing the mode of fixing by a wrench manually. When two pipelines are connected, one end of the flange with the hexagon socket type counter bore section is butted with the flange without the hexagon socket type counter bore section of the other pipeline, so that after a bolt penetrates through the bolt hole, the bolt head is locked by the hexagon socket type counter bore section of the flange, self-locking is realized, a nut can be directly screwed on the other side, labor input is reduced, and the efficiency of connecting the pipelines is improved.
The utility model aims to reduce the labor, tools and time for installing and removing pipelines, the pipeline flange plates are butted in the correct direction, only bolts are inserted to clamp the bolt heads in the grooves on the flanges to play a role in fixing, and then nuts are directly installed or removed to complete the operation, thereby greatly improving the operation efficiency.
The above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the utility model, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model.
