Description

Technical Field

[0001] This utility model relates to the field of water pressure testing technology, and in particular to an auxiliary device for pipeline water pressure testing. Background Technology

[0002] In traditional steel pipe production, process pipelines involve a wide variety of temperatures, pressures, and media. Post-installation hydrostatic testing is a crucial step in ensuring the final acceptance quality of the pipelines. Traditional single-pipe pressure testing methods are not only labor-intensive but also pose certain safety risks. Therefore, developing a multifunctional auxiliary tool for pipeline hydrostatic testing is necessary to improve work efficiency and safety.

[0003] In the traditional process of using pipeline water pressure testing devices, the pipeline to be tested needs to be connected to the testing device before testing. In actual use, due to the weight and length of the pipeline itself, it is difficult to align it during the process of transporting and connecting the pipeline. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] The purpose of this utility model is to address the technical problems existing in the background art. This utility model proposes an auxiliary device for pipeline water pressure testing. This utility model can effectively improve the efficiency and stability of pipeline connection during the pipeline water pressure testing process. Through the adjustment structure of this device, the device can achieve compatibility limiting for pipelines of different diameters.

[0006] This utility model proposes an auxiliary device for pipeline water pressure testing, including a mounting ring, a mounting component connected to one side of the mounting ring, a telescopic rod connected to the side of the mounting ring away from the mounting component, an electric telescopic rod connected to the side of the mounting ring away from the mounting component, a docking ring connected to the telescopic end of the telescopic rod, a docking ring connected to the telescopic end of the electric telescopic rod, a rotating component connected to the docking ring, and a clamping component connected to the rotating component.

[0007] By adopting the above technical solution, this solution can pull the pipeline closer to the testing equipment after the telescopic rod and electric telescopic rod are connected and fixed at both ends of the device, thereby reducing the manual handling cost when using the device and reducing the alignment difficulty during the docking process.

[0008] Preferably, the mounting component includes an arc-shaped mounting member that is slidably connected to the side of the mounting ring, a threaded bracket is connected to the side of the mounting ring, a threaded connecting rod is threadedly connected to the threaded bracket, and the threaded connecting rod is rotatably connected to the arc-shaped mounting member.

[0009] By adopting the above technical solution, this solution can adjust the sliding degree of the arc-shaped mounting part through the structure of the threaded connecting rod and the threaded bracket, thereby adjusting it according to the diameter of the mating joint of the detection device, which facilitates the installation and fixing of this device on the side of the detection device.

[0010] Preferably, the rotating component includes a docking post connected to the docking ring, a locking threaded rod threadedly connected to the top of the docking post, a rotating ring rotatably connected to the end of the docking post away from the docking ring, the rotating ring having an arc-shaped through groove, the locking threaded rod passing through the interior of the arc-shaped through groove, and a rotating knob at the top of the locking threaded rod, the diameter of the rotating knob being larger than the width of the arc-shaped through groove.

[0011] By adopting the above technical solution, this solution can adjust the clamping condition of the arc-shaped clamping component by rotating the rotating ring through the combination of the rotating ring and the locking threaded rod. At the same time, the structure of the locking threaded rod can lock the current rotation degree of the rotating ring, thereby preventing the arc-shaped clamping component from sliding unexpectedly.

[0012] Preferably, the clamping component includes a sliding blocking member slidably connected to the rotating ring. The rotating ring has a sliding groove facing the center of the rotating ring. The diameter of the sliding blocking member is larger than the width of the sliding groove. The bottom of the sliding blocking member has a connecting post that is slidably connected to the inner wall of the sliding groove. An arc-shaped clamping member is connected to the bottom of the connecting post. The top of the docking ring has an inclined groove, and the bottom of the arc-shaped clamping member is slidably connected to the inner wall of the inclined groove.

[0013] By adopting the above technical solution, this solution can achieve the effect of limiting and clamping pipes of different diameters through the arc-shaped clamping component. The inclined groove of this device can drive the arc-shaped clamping component to slide when the rotating ring rotates, thereby achieving the effect of clamping the outer arc surface of the pipe.

[0014] Preferably, the mounting ring, docking ring, and rotating ring are provided with through holes at their centers, the through holes having the same diameter, and the centers of the mounting ring, docking ring, and rotating ring are collinear.

[0015] By adopting the above technical solution, this solution can ensure accurate docking of the device through the collinear structure of the through holes, thus avoiding problems such as leakage at the docking joint.

[0016] Preferably, the telescopic rods are circumferentially distributed on the side of the mounting ring, and the electric telescopic rods are circumferentially distributed on the side of the mounting ring.

[0017] By adopting the above technical solution, this solution, through the circumferentially distributed telescopic rods and electric telescopic rods, ensures that the docking ring is subjected to uniform force and does not tilt, thus ensuring docking accuracy.

[0018] In summary, this utility model has at least one of the following beneficial effects:

[0019] This device, through its structure of telescopic rod and electric telescopic rod, enables the connection between the pipeline and the testing device. The electric telescopic rod allows the testing device to be brought close to the pipeline to be tested, and the locking threaded rod secures the rotating ring of the device, thus preventing accidental slippage of the arc-shaped clamping component.

[0025] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0026] Example 1: As Figures 1-3As shown, in order to solve the existing problems, this utility model discloses an auxiliary device for pipeline water pressure testing, including a mounting ring 1, a mounting component 2 connected to one side of the mounting ring 1, a telescopic rod 3 connected to the side of the mounting ring 1 away from the mounting component 2, an electric telescopic rod 4 connected to the side of the mounting ring 1 away from the mounting component 2, a docking ring 5 connected to the telescopic end of the telescopic rod 3, a docking ring 5 connected to the telescopic end of the electric telescopic rod 4, a rotating component 6 connected to the docking ring 5, and a clamping component 7 connected to the rotating component 6.

[0027] The mounting component 2 includes an arc-shaped mounting member 201 that is slidably connected to the side of the mounting ring 1. A threaded bracket 202 is connected to the side of the mounting ring 1. A threaded connecting rod 203 is threadedly connected to the threaded bracket 202. The threaded connecting rod 203 is rotatably connected to the arc-shaped mounting member 201.

[0028] The rotating component 6 includes a docking post 601 connected to the docking ring 5. A locking threaded rod 602 is threadedly connected to the top of the docking post 601. A rotating ring 603 is rotatably connected to the end of the docking post 601 away from the docking ring 5. The rotating ring 603 is provided with an arc-shaped through groove 604. The locking threaded rod 602 passes through the inside of the arc-shaped through groove 604. A rotating knob is provided at the top of the locking threaded rod 602. The diameter of the rotating knob is larger than the width of the arc-shaped through groove 604.

[0029] The clamping component 7 includes a sliding blocking member 702 that is slidably connected to the rotating ring 603. The rotating ring 603 is provided with a sliding through groove 701 facing the center of the rotating ring 603. The diameter of the sliding blocking member 702 is larger than the width of the sliding through groove 701. A connecting post is provided at the bottom of the sliding blocking member 702. The connecting post is slidably connected to the inner wall of the sliding through groove 701. An arc-shaped clamping member 703 is connected to the bottom of the connecting post. The top of the docking ring 5 is provided with an inclined groove 704. The bottom of the arc-shaped clamping member 703 is slidably connected to the inner wall of the inclined groove 704.

[0030] The specific working principle is as follows: This device can effectively improve the stability and accuracy of pipeline water pressure testing. Compared with traditional devices, this device improves the stability of pipeline connection by first clamping and limiting the distance and then shortening the gap. This reduces the difficulty of using the device and avoids manual handling.

[0031] When this device is in use, the structure of the mounting ring 1 and the arc-shaped mounting piece 201 facilitates the installation and fixation of this device on the side of the detection device, thereby achieving the pre-connection effect of this device. At this time, the electric telescopic rod 4 can drive the docking ring 5 away from the mounting ring 1 to slide. At this time, the docking ring 5 is close to the pipeline direction, and the pipeline is placed inside the docking ring 5. At this time, by unlocking the locking threaded rod 602, the rotating ring 603 can rotate. Rotating the rotating ring 603 causes multiple arc-shaped clamping pieces 703 to slide close to the center of the docking ring 5, thereby achieving the clamping effect on the pipeline. When the arc-shaped clamping pieces 703 come into contact with and are pressed against the outer arc surface of the pipeline, the locking threaded rod 602 is rotated to lock the rotating ring 603, preventing the arc-shaped clamping pieces 703 from sliding accidentally. At this time, the electric telescopic rod 4 retracts, thereby driving the pipeline closer to the detection device.

[0032] Example 2: Figures 1-3 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the above embodiment one, the auxiliary device for pipeline water pressure testing further includes: the mounting ring 1, the docking ring 5 and the rotating ring 603 are provided with through holes at their centers, the through holes are of the same size and diameter, the centers of the mounting ring 1, the docking ring 5 and the rotating ring 603 are collinear, the telescopic rod 3 is circumferentially distributed on the side of the mounting ring 1, and the electric telescopic rod 4 is circumferentially distributed on the side of the mounting ring 1.

[0033] The specific working principle is as follows: This device can effectively improve the stability and accuracy of pipe alignment during the pipe docking process. By pre-clamping and limiting the pipe, this device avoids the traditional process of manually handling pipes while aligning and detecting equipment, thus improving the efficiency of alignment and docking.

[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
