Description

Technical Field

[0001] The utility model relates to the technical field of temporary pipe orifice plugging, in particular to a device for temporary pipe orifice plugging. Background Technique

[0002] The construction of long-distance pipelines is characterized by long pipeline distances, complex terrain conditions, a large number of elbows, and many breakpoints. Therefore, during the construction of long-distance pipelines, the workload of temporarily plugging the end orifices is extremely large. The purpose of temporary plugging is to prevent small animals from entering the welded pipeline and also play a waterproof role. The traditional temporary pipe orifice plugging generally adopts the method of full welding of thin steel plates. Although this method can meet the waterproof and plugging effects, when welding the pipe orifice, the equipment needs to be redeployed, the steel plate needs to be cut and the groove needs to be reprocessed. In addition to increasing the project cost, the reprocessed groove often has low precision and also affects the welding quality. If intermittent welding of steel plates is used for temporary plugging, although the damage to the groove is minimized, it can only achieve the effect of temporary plugging and cannot achieve waterproofing, and there is even a risk of steel plate theft. Although other temporary plugging methods can meet the requirements of temporary plugging, they cannot meet the requirements of a large number of pluggings for long-distance pipelines due to defects such as complicated operation, inconvenient carrying, and time-consuming installation.

[0003] Based on this, a device for temporary pipe orifice plugging is now provided, which can eliminate the drawbacks of existing devices. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] In one embodiment, as Figures 1-4 shown, a device for temporarily plugging a pipe orifice includes a plugging sleeve 101. The plugging sleeve 101 is made of rubber material. A groove 102 is provided inside the plugging sleeve 101. A pipe orifice is inserted into the groove 102. A clamp 104 is provided outside the plugging sleeve 101. A locking bolt 105 for tightening the clamp 104 is rotatably provided on the clamp 104. The locking bolt 105 is a special-shaped countersunk bolt. A locking structure for locking the locking bolt 105 is inserted into the locking bolt 105. A pressing structure for pressing the groove 102 against the pipe orifice is provided on the plugging sleeve 101.

[0023] In this embodiment, the locking bolt 105 is rotated through the locking structure to tighten the clamp 104, so that the outer side of the plugging sleeve 101 closely adheres to the outer wall of the pipeline, and the plugging sleeve 101 seals the pipeline. After the clamp 104 is tightened, the pressing structure applies pressure to the end of the plugging sleeve 101, so that the groove 102 fits tightly with the pipe orifice, forming a second layer of seal.

[0024] In one embodiment, as Figure 2 and Figure 4 shown, the locking structure includes a bolt locking head 201 inserted on the locking bolt 105 and matching with the locking bolt 105. A force applying rod 202 is connected to the side surface of the bolt locking head 201. A scale disk 203 is connected to the side surface of the bolt locking head 201 away from the locking bolt 105. An indicating groove 204 is provided on the force applying rod 202 close to the scale disk 203. The indicating groove 204 corresponds to the scale disk 203. The bolt locking head 201 is rotated through the force applying rod 202, and the bolt locking head 201 drives the locking bolt 105 to rotate to tighten the clamp 104. In the initial state, the indicating groove 204 corresponds to the zero position on the scale disk 203. When the locking bolt 105 is rotated by using the force applying rod 202, the force applying rod 202 is bent, and the value corresponding to the indicating groove 204 on the force applying rod 202 on the scale disk 203 is the actual torque acting on the locking bolt 105, which is convenient for accurately achieving the best sealing effect during operation. After the clamp 104 is tightened, the bolt locking head 201 is pulled out from the locking bolt 105 to prevent unauthorized personnel from moving it randomly and affecting the plugging effect.

[0025] In one embodiment, as Figure 2 and Figure 3As shown, the pressing structure includes a connecting block 301 penetrating through the clamp 104. A pressing groove 302 is provided at the right end of the plugging sleeve 101. A pressing head 303 is provided at the opening of the pressing groove 302. The pressing head 303 is frustum-shaped. The side surface of the pressing head 303 contacts the opening of the pressing groove 302. A connecting bolt 304 penetrates through the pressing head 303. The connecting bolt 304 is threadedly connected to the connecting block 301. By pulling the pressing head 303 towards the connecting block 301 with the connecting bolt 304, the pressing head 303 squeezes the opening of the pressing groove 302, so that the position of the groove 102 corresponding to the opening of the pressing groove 302 is in close contact with the pipe orifice, forming a second layer of seal.

[0026] In one embodiment, as Figure 2 shown, a clamp groove 103 is provided on the outer side surface of the plugging sleeve 101. The clamp 104 is arranged in the clamp groove 103, so that when the clamp 104 is tightened, the plugging sleeve 101 is more evenly stressed and has a higher degree of fit with the pipe wall.

[0027] In one embodiment, as Figure 3 shown, the width of the groove 102 is the same as the thickness of the pipe, improving the sealing effect after the plugging sleeve 101 plugs the pipe orifice.

[0028] In one embodiment, as Figure 2 and Figure 3 shown, the clamp 104, the locking bolt 105, the connecting block 301, the pressing head 303 and the connecting bolt 304 are all made of stainless steel, with high strength, not easy to rust, and can be reused to reduce the plugging cost.

[0029] In one embodiment, as Figure 4 shown, an anti-slip sleeve 205 is provided at one end of the force increasing rod 202 away from the bolt locking head 201. When using the force increasing rod 202, it is not easy to slip between the hand and the force increasing rod 202.

[0030] The above embodiments disclose a device for temporary sealing of pipe orifices. During installation, first, the sealing sleeve 101 is sleeved on the pipe orifice, and then the clamp 104 is sleeved on the clamp groove 103. By rotating the bolt locking head 201 with the force-applying rod 202, the bolt locking head 201 drives the locking bolt 105 to rotate, causing the clamp 104 to contract and tighten, so that the outer side of the sealing sleeve 101 closely adheres to the outer wall of the pipeline, forming the first layer of seal while fixing the sealing sleeve 101 at the pipe orifice. When using the force-applying rod 202 to rotate the locking bolt 105, the force-applying rod 202 bends, and the value corresponding to the indicating groove 204 on the force-applying rod 202 on the scale disk 203 is the actual torque acting on the locking bolt 105, which is convenient for accurately achieving the best sealing effect during operation. By pulling the pressing head 303 towards the connecting block 301 with the connecting bolt 304, the pressing head 303 squeezes the opening of the pressing groove 302, so that the position where the groove 102 corresponds to the opening of the pressing groove 302 is in close contact with the pipe orifice, forming the second layer of seal, realizing the sealing of the pipeline and the protection of the pipe orifice groove.

[0031] As described above, the above are only the specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
