Abstract
Description
Technical Field
[0001] This application relates to the field of live pressure pipeline plugging technology, and more specifically, to a pipeline live pressure plugging clamp. Background Technology
[0002] Pipeline live sealing clamps can effectively seal pipeline leaks and damaged sections without stopping the flow of media. At the same time, with sufficient structural strength, they can withstand media pressure and external forces, providing a safe and reliable working space and mechanical support for subsequent sealing operations.
[0003] In related technologies, in order to solve the problem that the circumferential angle of the assembled tee assembly is difficult to synchronize accurately during the pressurized sealing operation of the pressure pipeline, for example, the patent with the prior art publication number CN222047043U provides a special clamp for pressurized sealing of the pressure pipeline. This clamp can easily adjust the angle of the two assembled tee assemblies by setting the synchronization component, making the installation process simpler and faster and reducing the construction difficulty.
[0004] While the existing technical solutions mentioned above have solved the problem of the difficulty in accurately synchronizing the circumferential angle of the assembled tee assembly by setting up a synchronization component, in order to increase the sealing performance, the assembled tee assembly is welded to the gap between it and the pressure pipeline. The synchronization component used for auxiliary adjustment is fixedly set at the bottom of the assembled tee assembly, which will occupy the space under the pipeline and may limit the operating space of personnel during subsequent pipeline inspection and maintenance. In addition, each assembled tee assembly requires a matching rotating rod, which increases the number of parts and the assembly complexity.
[0005] In view of this, we propose a pipeline pressurized plugging clamp. Utility Model Content
[0006] The purpose of this application is to provide a pipeline pressurized sealing clamp that can effectively solve the problems in the prior art, such as the excessive space occupied under the pipeline due to the synchronous component being fixedly set at the bottom of the assembled tee assembly, which restricts subsequent inspection and maintenance operations, and the increased number of parts and assembly complexity caused by each assembled tee assembly needing to be matched with a dedicated rotating rod.
[0007] This application provides a pipeline live plugging clamp, comprising:
[0008] Lower clamping plates, two of which are provided;
[0009] The upper clamping plate is located on top of the lower clamping plate and is used to clamp the pipe body in conjunction with the lower clamping plate.
[0010] A clamp valve is located at the top of the upper clamp plate;
[0011] The synchronization component, located at the bottom of the lower clamping plate, is used to synchronize the adjustment of the two sets of lower clamping plates and the upper clamping plate.
[0012] Bolts are located on the inside of the lower clamping plate and the synchronization assembly to secure the lower clamping plate and the synchronization assembly.
[0013] As an optional solution to the technical solution of this application, a bottom cover is fixedly provided at the bottom of the lower clamping plate, and a threaded groove is provided at the bottom of the bottom cover. The synchronization component includes two sliders, which are respectively disposed at the bottom of the corresponding lower clamping plate. An opening is provided on the inner side of the slider, and the bolt is threaded to the corresponding threaded groove.
[0014] As an optional solution to the technical solution of this application, the bottom of the bottom cover is provided with a positioning groove, the positioning groove is set as a conical groove, and the top of the slider is provided with a positioning block corresponding to the positioning groove.
[0015] As an optional solution to the technical solution of this application, the slider is slidably disposed on the inner side of the slide rail, and a mounting plate is fixedly disposed on the outer side of the slide rail.
[0016] As an optional solution to the technical solution of this application, a sliding sleeve is detachably provided on the outer side of one of the slide rails via an installation component, and a sliding rod is slidably provided on the inner side of the sliding sleeve. One end of the sliding rod is detachably connected to the outer side of the other slide rail via an installation component.
[0017] As an optional solution to the technical solution of this application, the lower clamping plate and the upper clamping plate are fixed by screws and nuts, and the inner sides of the lower clamping plate and the upper clamping plate are fixedly provided with a bonding plate.
[0018] As an optional solution to the technical solution in this application, a sealing ring is provided between the bonding plate and the lower clamping plate and the upper clamping plate, and the bonding plate is welded and fixed to the outside of the pipe body.
[0019] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0020] (1) This application uses bolts to connect the synchronization component to the lower clamping plate. After the upper and lower clamping plates are fixed to the outside of the pipe body, the lower clamping plate and the synchronization component can be disassembled by removing the bolts, which prevents the synchronization component from occupying the bottom space of the pipe. Furthermore, the synchronization component can be reused repeatedly. Therefore, it effectively solves the problems of excessive space occupation under the pipe caused by the synchronization component being fixed at the bottom of the assembled tee assembly, which restricts subsequent inspection and maintenance operations, and the increased number of parts and assembly complexity caused by each assembled tee assembly needing to be matched with a dedicated rotating rod.
[0021] (2) This application uses fasteners to install the sliding sleeve and sliding rod on the outside of the slide rail, which facilitates the installation of the sliding sleeve and sliding rod, and allows the slide rail, sliding sleeve and sliding rod to be disassembled and stored, saving storage space. The disassembly and assembly of the mounting plate facilitates the disassembly and maintenance of the slider. Attached Figure Description

Detailed Implementation
[0027] The present application will be further described in detail below with reference to the accompanying drawings.
[0028] Reference Figure 1 , Figure 2 and Figure 3 This application discloses a pipeline pressurized sealing clamp, including a lower clamping plate 1, of which two are provided. An upper clamping plate 2 is provided on the top of the lower clamping plate 1 for clamping the pipeline body 100 in conjunction with the lower clamping plate 1. A clamping valve 3 is provided on the top of the upper clamping plate 2. A synchronization component 4 is provided on the bottom of the lower clamping plate 1 for synchronously adjusting the two sets of lower clamping plates 1 and upper clamping plates 2. Bolts 5 are provided on the inner side of the lower clamping plate 1 and the synchronization component 4 for fixing the lower clamping plate 1 and the synchronization component 4. The lower clamping plate 1 and the upper clamping plate 2 are fixed by screws 6 and nuts 61. A bonding plate 7 is fixedly provided on the inner side of both the lower clamping plate 1 and the upper clamping plate 2 for bonding to the outer side of the pipeline body 100. A sealing ring is provided between the bonding plate 7 and the lower clamping plate 1 and the upper clamping plate 2.
[0029] First, connect the two lower clamping plates 1 together through the synchronization component 4, so that the two lower clamping plates 1 are placed on both sides of the target position of the pipe body 100 to be sealed, ensuring that the fitting plate 7 fixed on the inner side of the lower clamping plate 1 can be initially aligned with the outer side of the pipe body 100. Through the linkage adjustment function of the synchronization component 4, push the two lower clamping plates 1 to rotate synchronously around the circumference of the pipe body 100 until the position and angle of the two sets of lower clamping plates 1 meet the docking requirements of the subsequent upper clamping plate 2, ensuring that the subsequently assembled lower clamping plate 1 and upper clamping plate 2 can accurately match the bypass pipe interface.
[0030] After the synchronous adjustment is completed, the upper clamping plate 2 is placed on top of the lower clamping plate 1 to fix the lower clamping plate 1 and the upper clamping plate 2. The upper clamping plate 2 and the lower clamping plate 1 continuously apply clamping force towards the pipe body 100 until the bonding plate 7 is completely attached to the outer side of the pipe body 100 and the sealing ring is fully compressed to achieve the best sealing effect. The connection between the bonding plate 7 and the outer side of the pipe body 100 is welded to completely seal any possible small gaps. After the welding is completed, the clamping plate valve 3 at the top of the upper clamping plate 2 can be opened to connect the bypass pipeline to realize the medium diversion, providing a safe and sealed working environment for subsequent pipeline leak repair.
[0031] Reference Figure 3 and Figure 4 The bottom of the lower clamping plate 1 is fixedly provided with a bottom cover 11. The bottom of the bottom cover 11 is provided with a threaded groove 111. The synchronization component 4 includes two sliders 41. The two sliders 41 are respectively provided at the bottom of the corresponding lower clamping plate 1. The inner side of the slider 41 is provided with an opening 411. The bolt 5 is threaded to the corresponding threaded groove 111. The bottom of the bottom cover 11 is provided with a positioning groove 112. The positioning groove 112 is set as a conical groove. The top of the slider 41 is provided with a positioning block 412 corresponding to the positioning groove 112.
[0032] Align the slider 41 with the bottom cover 11, and engage the positioning groove 112 with the positioning block 412 to achieve precise positioning. Then, pass the bolt 5 through the opening 411 and thread it into the threaded groove 111 to complete the temporary fixation of the lower clamping plate 1 and the synchronization component 4, ensuring that the two sets of lower clamping plates 1 can be adjusted in conjunction with the synchronization component 4.
[0033] Reference Figure 1 , Figure 2 and Figure 4 The slider 41 is slidably disposed on the inner side of the slide rail 42, and the outer side of the slide rail 42 is fixedly disposed on the mounting plate 421. A sliding sleeve 43 is detachably disposed on the outer side of one of the slide rails 42 through the mounting member 432. A sliding rod 431 is slidably disposed on the inner side of the sliding sleeve 43. One end of the sliding rod 431 is detachably disposed on the outer side of the other slide rail 42 through the mounting member 432.
[0034] The sliding rail 42 and slider 41 are slidably configured so that the synchronization component 4 can be applied to the pipe body 100 at different positions at both ends. The sliding sleeve 43 and sliding rod 431 are slidably configured so that they can be applied to two lower clamping plates 1 at different distances. This allows the synchronization component 4 to make the two lower clamping plates 1 move synchronously along the circumference of the pipe body 100. The position and angle of the lower clamping plates 1 are adjusted so that the circumferential angle of the clamping valve 3 at the top of the upper clamping plate 2 installed later is consistent, which meets the requirements for bypass pipeline connection. The sliding rod 431 and sliding sleeve 43 are separated by the mounting piece 432 for easy storage. By disassembling the mounting plate 421, the slider 41 can be taken out from the inside of the sliding rail 42 for easy maintenance of the slider 41.
[0035] In summary, when using the pipeline pressurized plugging clamp disclosed in this application embodiment, the specifications of the lower clamp 1 and the upper clamp 2 are first determined according to the specifications of the pipeline body 100 to be plugged.
[0036] Align the slider 41 with the bottom cover 11, and engage the positioning groove 112 with the positioning block 412 to achieve precise positioning. Then, pass the bolt 5 through the opening 411 and thread it into the threaded groove 111 to complete the temporary fixation of the lower clamping plate 1 and the synchronization component 4, ensuring that the two sets of lower clamping plates 1 can be adjusted in conjunction with the synchronization component 4.
[0037] Among them, the slide rail 42 and the slider 41 are slidably set so that the synchronization component 4 can be applied to the pipe body 100 at different positions at both ends. The slide sleeve 43 and the slide rod 431 are slidably set so that they can be applied to two lower clamping plates 1 at different distances. This allows the synchronization component 4 to make the two lower clamping plates 1 move synchronously along the circumference of the pipe body 100, and adjust the position and angle of the lower clamping plates 1 so that the circumferential angle of the clamping plate valve 3 at the top of the subsequently installed upper clamping plate 2 is consistent, thus meeting the bypass pipeline docking requirements.
[0038] After the angle adjustment is completed, the upper clamping plate 2 is placed on top of the lower clamping plate 1 so that the upper clamping plate 2 and the lower clamping plate 1 together wrap the pipe body 100. Then, the screw 6 is passed through the corresponding mounting holes of the upper clamping plate 2 and the lower clamping plate 1, and the nut 61 is tightened to achieve a stable clamping of the pipe body 100 by the upper clamping plate 2 and the lower clamping plate 1. Finally, the bonding plate 7 is welded to the outside of the pipe body 100 to further enhance the sealing and fixing effect.
[0039] After the upper clamping plate 2 and the lower clamping plate 1 are welded and fixed to the pipe body 100, unscrew the bolts 5 to separate the lower clamping plate 1 and the synchronization component 4. This prevents the synchronization component 4 from occupying the space below the pipe body 100 for a long time and allows the synchronization component 4 to be reused. Separate the slide rod 431 and the slide sleeve 43 through the mounting piece 432 for easy storage later. By disassembling the mounting plate 421, the slider 41 can be taken out from the inside of the slide rail 42 for easy maintenance later.
