Description

Technical Field

[0001] The invention relates to the technical field of leather cups, and in particular to a pipeline plugging leather cup. Background Art

[0002] During the use of oil and gas pipelines, due to internal or external factors, the pipelines may be partially rotten, deformed or damaged, resulting in pipeline safety hazards. When repairing or replacing the potential danger parts, the potential danger section of the pipeline must be blocked first, and usually a sealing cup is needed to block the pipeline;

[0003] The existing pipe plugging cups are prone to unsatisfactory plugging effects during use.

[0004] The reason for this problem is that during the sealing process, the leather cup is generally inserted directly into the interior of the pipe, and the sealing surface of the leather cup is generally flat, which makes it easy for the leather cup to be wrinkled after being inserted into the pipe, affecting the sealing effect. At the same time, during the sealing process, if the impact force of oil and water is large, there is no existing mechanism for fixing the leather cup, and the leather cup may be detached during the sealing process, affecting the normal sealing work of the leather cup for oil and water. In view of the above problems, the present invention provides a pipeline pressure plugging leather cup. Summary of the invention

[0005] In order to solve the above-mentioned deficiencies in the prior art, the present invention proposes a pipeline pressure plugging leather cup.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: a pipe plugging leather cup, comprising a leather cup bottom, the bottom end of the leather cup bottom is provided with a leather cup outer edge, the bottom end of the leather cup outer edge is provided with multiple groups of support plates, the support plates have the function of supporting and positioning the position of the leather cup outer edge, the inner walls of the multiple groups of support plates are provided with multiple groups of fixing plates, and the fixing plates have the function of fixing the support plates.

[0007] Preferably, a curved portion is provided between the bottom of the leather cup and the outer edge of the leather cup, and a plurality of groups of support plates are fixedly mounted in a ring shape on the lower surface of the outer edge of the leather cup.

[0008] Preferably, a cylinder is installed on the inner wall of the bottom of the leather cup, and a mounting disc is fixedly connected to the output end of the cylinder.

[0009] Preferably, the inner wall of the outer edge of the leather cup is fixedly connected with four sets of hinge blocks, and the interior of the hinge block is hinged with an adjustment rod.

[0010] Preferably, the other ends of the multiple groups of adjustment rods are respectively hinged inside the mounting disc, and a support rod is provided at the bottom end of the mounting disc.

[0011] Preferably, the bottom end of the mounting disc slides inside the support rod, and a mounting ring is sleeved on the outer surface of the support rod.

[0012] Preferably, the outer surface of the mounting ring is fixedly connected with four sets of threaded barrels, and the internal threads of the threaded barrels are connected with threaded rods.

[0013] Preferably, the other end of the threaded rod rotates inside the fixing plate, and the outer surfaces of the multiple groups of fixing plates are all in contact with the inner walls of the multiple groups of supporting plates.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the pipeline plugging leather cup can drive the outer edge of the leather cup to seal the inner wall of the pipeline through the cooperation between the arranged cylinder and the adjusting rod, and can avoid direct insertion, so that the outer wall of the outer edge of the leather cup and the pipeline generate an extrusion force, resulting in damage to the outer wall of the outer edge of the leather cup, thereby affecting the sealing of the outer edge of the leather cup, improving the sealing effect of the outer edge of the leather cup, and at the same time, the four groups of support plates can be firmly fixed on the inner wall of the pipeline, so that the support plates can support and position the outer edge of the leather cup, thereby improving the effect of the outer edge of the leather cup on sealing oil and water, and there will be no phenomenon that the large impact force of oil and water pushes the outer edge of the leather cup to separate from the inner wall of the pipeline.

After the leather cup outer edge 2 is propped up, the outer wall of the leather cup outer edge 2 is larger than the inner wall of the pipe, and the pipe can be sealed. The outer edge of the leather cup outer edge 2 is arranged in an arc shape, and the support plate 3 has the function of supporting and positioning the position of the leather cup outer edge 2. The inner walls of the plurality of support plates 3 are all provided with a plurality of fixing plates 302, and the fixing plates 302 have the function of fixing the support plates 3. When in use, first fill the device into the required Inside the blocked pipe, at this time, the support rod 4 is located in the middle of the inside of the pipe, and then, by starting the cylinder 201, the mounting disc 204 at the bottom is moved upward, and the bottom ends of the multiple groups of adjusting rods 202 are hinged inside the mounting disc 204, and the top ends of the adjusting rods 202 are hinged inside the hinge block 203. At the same time, the outer edge of the leather cup 2 is driven to open outward, and the bending part 101 is driven to bend. After opening, the outer edge of the outer edge of the leather cup 2 can block the inner wall of the pipe, thereby achieving the purpose of blocking the pipe.
