Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, and in particular to a straight pipe sealing tool. Background Technology

[0002] A pipeline is a system of pipes, fittings, and valves used to transport gases, liquids, or fluids containing solid particles. Fluids are typically pressurized by blowers, compressors, pumps, and boilers before flowing from high-pressure areas to low-pressure areas within the pipeline. They can also be transported using their own pressure or gravity. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance oil transportation, and various industrial installations.

[0003] In general, when a pipeline leaks, it is necessary to carry out emergency repairs and plugging the leak in a timely manner to reduce property damage, personal injury, and environmental pollution. Currently, pipeline leaks are usually temporarily plugged using a combination of pressure blocks and pipe clamps. However, for leaks at pipelines with high transmission pressure, the injection pressure is high, making it inconvenient to install pipe clamps at the leak point, affecting plugging efficiency, and the structural stability is not high. Utility Model Content

[0004] The purpose of this invention is to provide a straight pipe plugging tool, which has a simple structure, high stability in plugging leak points, and good plugging effect.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A straight pipe plugging tool is provided, including a clamp, a plugging component, and an adjusting assembly. The clamp has a connecting portion and a first mounting portion and a second mounting portion spaced apart along a first direction. The first mounting portion is connected to the second mounting portion via the connecting portion. The plugging component is disposed on the side of the first mounting portion facing the second mounting portion. The adjusting assembly is disposed on the second mounting portion and includes a first driving component and a locking component. The first driving component is movably connected to the second mounting portion and is capable of pushing the straight pipe to move along the first direction and abutting against the plugging component for sealing. The locking component is used to selectively fix the first driving component.

[0007] As a preferred embodiment of a straight pipe plugging tool, the first driving component includes an eccentric wheel, which is rotatably connected to the second mounting part. The outer circumference of the eccentric wheel has a pressing surface, which pushes the straight pipe to abut against the plugging component. Around a first rotation direction of the eccentric wheel, the eccentric wheel can press against the straight pipe, and the distance between the pressing surface and the rotation axis of the eccentric wheel gradually decreases.

[0008] As a preferred embodiment of a straight pipe plugging tool, the second mounting part is provided with a receiving groove through the first direction. The eccentric wheel is rotatably connected to the two groove walls of the receiving groove along the second direction. The outer periphery of the eccentric wheel is provided with multiple slots, all of which are spaced apart around the outer periphery of the eccentric wheel. The bottom of the receiving groove is provided with an installation groove, the length of which extends along a third direction. The locking member includes a second driving member and a locking pin. The second driving member is disposed in the installation groove and can drive the locking pin to selectively engage or disengage with any of the slots. The first direction, the second direction, and the third direction are arranged at an angle to each other.

[0009] As a preferred embodiment of a straight pipe plugging tool, the second driving component includes an elastic element and an unlocking block. The locking pin is slidably disposed within the mounting groove. The locking pin is connected to the bottom of the mounting groove via the elastic element. The elastic element always has a tendency to drive the locking pin to press against the eccentric rotating wheel. At least one side of the second mounting portion along the second direction is provided with a limiting groove. The length of the limiting groove extends along the third direction and communicates with the mounting groove. The unlocking block is disposed on the locking pin and is slidably connected to the limiting groove. The end of the unlocking block away from the locking pin extends outside the limiting groove.

[0010] As a preferred embodiment of a straight pipe plugging tool, along the second rotation direction of the eccentric wheel, a plurality of ratchet teeth are sequentially inclined on the outer periphery of the eccentric wheel, and a groove is formed between two adjacent ratchet teeth. A pawl is provided at the end of the locking pin away from the elastic element. The pawl cooperates with the groove so that the eccentric wheel can only move in one direction around the first rotation direction of the eccentric wheel, and the first rotation direction is opposite to the second rotation direction.

[0011] As a preferred embodiment of a straight pipe sealing tool, the mating surface is provided with multiple anti-slip grooves at intervals.

[0012] As a preferred embodiment of the straight pipe plugging tool, the first driving component further includes a handle, which is disposed on the outer periphery of the eccentric wheel and rotates around the first rotation direction of the eccentric wheel. The connection position between the handle and the eccentric wheel is spaced apart from the abutting surface.

[0013] As a preferred embodiment of the straight pipe plugging tool, the straight pipe plugging tool further includes a first adjusting screw, a first connecting hole is provided through the first mounting part along the first direction, the first adjusting screw is threadedly engaged with the first connecting hole, and the plugging member is rotatably connected to one end of the first adjusting screw adjacent to the straight pipe.

[0014] As a preferred embodiment of the straight pipe plugging tool, the straight pipe plugging tool further includes a support block and a second adjusting screw. The connecting part is provided with a second connecting hole through the second direction. The second adjusting screw is threadedly engaged with the second connecting hole. The support block is rotatably connected to one end of the second adjusting screw adjacent to the straight pipe. The support block can abut against the straight pipe. The second direction is set at an angle to the first direction.

[0015] As a preferred embodiment of the straight pipe plugging tool, the straight pipe plugging tool further includes a sealing gasket, and the sealing gasket is provided on the side of the plugging component and / or the support block facing the straight pipe.

[0016] The beneficial effects of this utility model are as follows: By fitting the sealing component of the straight pipe sealing tool to the leakage point of the straight pipe, and using the first driving component to push the straight pipe and the sealing component to abut together, the straight pipe is locked between the sealing component and the first driving component, thereby achieving temporary and rapid sealing of the leakage point, effectively avoiding greater losses. It is convenient to operate, saves time and effort, and has high sealing efficiency. By fixing the first driving component with the locking component, the relative position of the first driving component after pushing the straight pipe and the sealing component to abut together can be effectively guaranteed, so that the sealing component always stably seals the leakage point and ensures the sealing stability of the straight pipe sealing tool.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] like Figures 1 to 4As shown, the straight pipe sealing tool of this utility model embodiment includes a clamp 1, a sealing member 2, and an adjustment assembly 3. The clamp 1 has a connecting part 11, and a first mounting part 12 and a second mounting part 13 arranged at intervals along a first direction (the first direction is the X direction shown in the figure). The first mounting part 12 is connected to the second mounting part 13 through the connecting part 11. The sealing member 2 is disposed on the side of the first mounting part 12 facing the second mounting part 13. The adjustment assembly 3 is disposed on the second mounting part 13. The adjustment assembly 3 includes a first driving member 31 and a locking member 32. The first driving member 31 is movably connected to the second mounting part 13, and the first driving member 31 can push the straight pipe to move along the first direction and abut against the sealing member 2 for sealing. The locking member 32 is used to selectively fix the first driving member 31.

[0029] Understandably, by fitting the sealing component 2 of the straight pipe sealing tool against the leak point of the straight pipe, and using the first driving component 31 to push the straight pipe and the sealing component 2 together, the straight pipe is locked between the sealing component 2 and the first driving component 31, thereby achieving temporary and rapid sealing of the leak point, effectively avoiding greater losses. The operation is convenient, time-saving, labor-saving, and highly efficient. By fixing the first driving component 31 with the locking component 32, the relative position of the first driving component 31 after pushing the straight pipe and the sealing component 2 together can be effectively guaranteed, ensuring that the sealing component 2 always stably seals the leak point and guarantees the sealing stability of the straight pipe sealing tool.

[0030] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the first driving component 31 includes an eccentric wheel, which is rotatably connected to the second mounting part 13. The outer circumference of the eccentric wheel has a pressing surface 311. The pressing surface 311 pushes the straight pipe to abut against the sealing component 2. Around the first rotation direction of the eccentric wheel, the eccentric wheel can press against the straight pipe. The distance between the pressing surface 311 and the rotation axis of the eccentric wheel gradually decreases. The pressing surface 311 has an arc surface structure. By rotating the eccentric wheel, the distance between the point on the pressing surface 311 that abuts against the straight pipe and the eccentric wheel increases, thereby gradually pushing the straight pipe to abut against the sealing component 2. The structure is simple and convenient to use.

[0031] In addition to the eccentric wheel, the first driving component 31 can also be a linear drive mechanism such as a cylinder, hydraulic cylinder, or electric cylinder. Taking a cylinder as an example, the locking component 32 is a controller. The cylinder pushes the straight pipe to press against the sealing component 2, and the controller controls the cylinder to always maintain this pressing state.

[0032] Furthermore, such as Figure 2 , Figure 3 and Figure 4As shown, the second mounting part 13 is provided with a receiving groove 131 through the first direction. The eccentric wheel is rotatably connected to the two groove walls of the receiving groove 131 along the second direction (the second direction is the Y direction shown in the figure). Multiple slots 312 are provided on the outer periphery of the eccentric wheel. All the slots 312 are spaced apart around the outer periphery of the eccentric wheel. An installation groove 132 is opened at the bottom of the receiving groove 131. The length of the installation groove 132 extends along the third direction (the third direction is the Z direction shown in the figure). The locking member 32 includes a second driving member 321 and a locking pin 322. The second driving member 321 is disposed in the installation groove 132. The second driving member 321 can drive the locking pin 322 to selectively engage or disengage with any slot 312. The first direction, the second direction and the third direction are arranged at an angle to each other. When the eccentric wheel rotates to the point where the abutment surface 311 can press the straight pipe against the abutment surface 311 and the sealing member 2, the second driving member 321 drives the locking pin 322 to move toward the eccentric wheel and lock it in the slot 312, thereby limiting the rotation of the eccentric wheel and locking the eccentric wheel so that the eccentric wheel always maintains the state of pushing the straight pipe against the sealing member 2. When it is necessary to remove it, the second driving member 321 drives the locking pin 322 to move away from the eccentric wheel, so that the locking pin 322 separates from the slot 312. At this time, the eccentric wheel is rotated in the opposite direction of the abutment to the eccentric wheel, so that the abutment surface 311 and the straight pipe are gradually separated, and the straight pipe sealing tool can be removed. The structure is simple and the operation is convenient.

[0033] Specifically, such as Figure 3As shown, the second driving member 321 includes an elastic member 3211 and an unlocking block 3212. The locking pin 322 is slidably disposed in the mounting groove 132. The locking pin 322 is connected to the bottom of the mounting groove 132 through the elastic member 3211. The elastic member 3211 always has the tendency to drive the locking pin 322 to press against the eccentric rotating wheel. The second mounting part 13 is provided with a limiting groove 133 on at least one side of the two sides along the second direction. The length of the limiting groove 133 extends along the third direction and communicates with the mounting groove 132. The unlocking block 3212 is disposed on the locking pin 322 and is slidably connected to the limiting groove 133. The end of the unlocking block 3212 away from the locking pin 322 extends out of the limiting groove 133. The elastic element 3211 can be directly made of a spring. Driven by the spring, the locking pin 322 always tends to move towards the eccentric wheel. When it rotates to the eccentric wheel and presses against the straight pipe, the end of the locking pin 322 away from the spring extends out of the mounting groove 132 and is locked in the groove 312 under the drive of the spring, so as to lock the eccentric wheel and secure the connection, ensuring the sealing stability of the straight pipe sealing tool. When it is necessary to remove the straight pipe sealing tool, pull the unlocking block 3212 to move away from the eccentric wheel, so that the locking pin 322 can overcome the elastic force of the spring and move away from the eccentric wheel, so that the locking pin 322 separates from the groove 312. At this time, the operator can rotate the eccentric wheel to disengage from the straight pipe, which is convenient, quick and saves time and effort.

[0034] Of course, the second driving component 321 is not limited to the form of the elastic component 3211 and the unlocking block 3212 mentioned above. It can also be one of the linear drive mechanisms such as a cylinder, a hydraulic cylinder, or an electric cylinder. Taking a cylinder as an example, the cylinder is set in the mounting groove 132, and the locking pin 322 is set at the driving end of the cylinder. An external controller is used to control the extension and retraction of the driving end, thereby controlling the locking pin 322 to selectively engage or disengage from the locking groove 312.

[0035] In this embodiment, along the second rotation direction of the eccentric wheel, a plurality of ratchet teeth 313 are sequentially inclined on the outer periphery of the eccentric wheel, and a groove 312 is formed between two adjacent ratchet teeth 313. A pawl 3221 is provided at the end of the pin 322 away from the elastic member 3211. The pawl 3221 cooperates with the groove 312 to restrict the eccentric wheel to only move in one direction around the first rotation direction of the eccentric wheel. The first rotation direction is opposite to the second rotation direction. Understandably, the ratchet and pawl 3221 work together to limit the first rotation direction of the eccentric wheel. That is, the eccentric wheel can only rotate in the direction of gradually pressing against the straight tube. This allows the pawl 3221 to be pushed by the ratchet 313 to move away from the eccentric wheel and separate from the slot 312 during the rotation of the eccentric wheel. When the next slot 312 is opposite to the pawl 3221, the pawl 3221 is engaged in the next slot 312 under the drive of the spring until the eccentric wheel and the straight tube are completely pressed together.

[0036] For example, taking the clockwise rotation of the eccentric wheel to press against the straight pipe as an example, the outer periphery of the eccentric wheel is provided with a plurality of ratchet teeth 313 arranged counterclockwise. The pawl 3221 is provided with a corresponding inclined surface. The inclined surface is inclined from the end away from the sealing member 2 to the end close to the sealing member 2 and in the direction of eccentric rotation. When the eccentric wheel is rotated clockwise, the inclined ratchet teeth 313 can push the inclined surface to move away from the eccentric wheel to gradually engage with the next slot 312 until the eccentric wheel is pressed against the straight pipe. Conversely, when the eccentric wheel is rotated counterclockwise, the slot 312 is locked to the end of the pawl 3221 supported by the groove wall of the mounting groove 132, and the pawl 3221 cannot be pushed to move away from the eccentric wheel. This achieves the limitation of unidirectional movement of the eccentric wheel, avoids the eccentric wheel from loosening, and ensures the stability of the clamping between the eccentric wheel and the straight pipe.

[0037] Optionally, the mating surface 311 is provided with multiple anti-slip grooves at intervals. The anti-slip grooves effectively increase the friction of the mating surface 311, preventing slippage between the mating surface 311 and the straight pipe, and improving the stability of the mating between the mating surface 311 and the straight pipe. Of course, the openings of the anti-slip grooves can be rounded to reduce damage to the straight pipe from sharp edges, ensuring the service life of the eccentric wheel and the straight pipe.

[0038] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the first driving component 31 also includes a handle 314, which is disposed on the outer periphery of the eccentric wheel, around the first rotation direction of the eccentric wheel. The connection position of the handle 314 with the eccentric wheel and the abutment surface 311 are spaced apart. The handle 314 facilitates the operator to hold the handle 314 to rotate the eccentric wheel, improving the convenience of the eccentric wheel rotation operation.

[0039] Furthermore, since the driving distance of the eccentric wheel is limited, the straight pipe plugging tool also includes a first adjusting screw 4. A first connecting hole is provided through the first mounting part 12 along a first direction. The first adjusting screw 4 is threaded into the first connecting hole, and the plugging component 2 is rotatably connected to one end of the first adjusting screw 4 adjacent to the straight pipe. By turning the first adjusting screw 4, the distance between the plugging component 2 and the eccentric wheel can be adjusted, thereby adapting to the plugging of straight pipes of different diameters and improving the versatility of the straight pipe plugging tool.

[0040] Optionally, the sealing element 2 is an arc-shaped block. The arc-shaped block has a higher degree of fit and coordination with the outer periphery of the straight pipe, increasing the contact area between the straight pipe and the sealing element 2 and ensuring the sealing effect. Therefore, the sealing element 2 is rotatably configured with the first adjusting screw 4, and the rotation center axis of the sealing element 2 extends along the central axis of the first adjusting screw 4. This allows the sealing element 2 to be rotated after the height is adjusted by the first adjusting screw 4, so that the inner arc surface of the sealing element 2 fits against the straight pipe.

[0041] Furthermore, the straight pipe plugging tool also includes a support block 5 and a second adjusting screw. A second connecting hole is provided through the connecting part 11 along a second direction. The second adjusting screw is threaded into the second connecting hole. The support block 5 is rotatably connected to one end of the second adjusting screw adjacent to the straight pipe, and the support block 5 can abut against the straight pipe. By adjusting the second adjusting screw to make the support block 5 press firmly against the straight pipe, the support point of the straight pipe plugging tool for plugging the straight pipe is enhanced, thereby ensuring the support stability of the straight pipe plugging tool when plugging the straight pipe.

[0042] In addition, the straight pipe sealing tool also includes a sealing gasket 7. The sealing gasket 7 is located on the side of the sealing component 2 facing the straight pipe. The sealing gasket 7 allows for better deformation and contact with the straight pipe to seal leaks, improving the sealing performance. Furthermore, the sealing gasket 7 is made of a flexible material, preventing rigid contact between the sealing component 2 and the straight pipe, thus ensuring the service life of both. Similarly, the support block 5 has a sealing gasket 7 on the side facing the straight pipe to mitigate the rigid impact between the support block 5 and the straight pipe, improving the safety and protection of both the straight pipe and the support block 5.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
