Description

Technical Field

[0001] This utility model relates to the field of pipeline water pressure testing, specifically to a support device for a pipeline water pressure testing plug. Background Technology

[0002] Pipeline hydrostatic testing is an important step in verifying the strength, sealing, and pressure-bearing capacity of pipeline systems, and it is widely used in municipal engineering, petrochemicals, water conservancy construction, and other fields.

[0003] Existing pipeline hydrostatic testing involves installing a back wall on the outside of the pipeline for sealing and support, and then filling the pipeline with high-pressure water to test its internal pressure resistance. Specifically, a ring of sandbags is placed at the pipeline end, forming a main structure with a steel frame. Concrete is then poured to fill the gaps, ensuring that the main structure aligns with the sealing head inside the pipeline end. Finally, jacks are used to seal the pipeline. This construction process is complex and inefficient. Furthermore, the test requires waiting for the concrete to solidify and reach sufficient strength before it can proceed, making the overall testing time-consuming. Utility Model Content

[0004] This invention provides a support device for a pipe pressure test plug, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A support device for a pipe hydrostatic test plug, wherein the plug is disposed inside the pipe end, comprising:

[0007] The upright plate has a mounting plate on the front, and a telescopic rod perpendicular to the mounting plate is set at each of the four corners of the mounting plate. One end of the telescopic rod is fixedly connected to the mounting plate.

[0008] The top plate is hinged to the other end of the telescopic rod on its back side, and its front side is used to abut against the sealing head.

[0009] The diagonal brace has one end hinged to the back of the upright plate and the other end inserted into the ground; the length of the diagonal brace is adjustable.

[0010] A horizontal plate is set at the bottom of the vertical plate, and the vertical plate and the horizontal plate are rotatably connected; the lower surface of the horizontal plate is provided with several vertical fixing rods, which are used to insert into the ground.

[0011] Specifically, the diagonal brace includes a sleeve section, the top of which is hinged to the vertical plate, and a rotating sleeve coaxial with the sleeve section at the bottom, the rotating sleeve having an internal thread; it also includes a screw rod, which is threadedly engaged with the rotating sleeve, the top of which is inserted into the sleeve section, and the bottom of which has a fork for inserting into the ground.

[0012] Furthermore, the rotating sleeve is annular, with a connecting groove on its upper end face. The cross-sectional shape of the connecting groove is an inverted T-shape; the bottom of the sleeve section matches the shape of the connecting groove.

[0013] In particular, the mounting plate is also equipped with a support rod, which is connected to the ball joint connector and then connected to the center of the top plate via the ball joint connector.

[0014] Specifically, each side of the horizontal plate is provided with a base, and the base is provided with a rotating bearing; the two opposite sides of the vertical plate are provided with a rotating shaft, and the two rotating shafts are inserted into and fixed with the two rotating bearings respectively, so that the vertical plate can rotate around the rotating shaft.

[0015] Specifically, the horizontal plate is provided with a lifting push rod on the outer side of each of the two bases, and the output end of the top of the lifting push rod is provided with a long strip-shaped lifting plate; the lower surface of each end of the lifting plate is provided with a mounting rod perpendicular to the lifting plate, and the bottom of the mounting rod is provided with a pulley for supporting the ground.

[0016] In particular, a support plate is provided on the side wall of the horizontal plate, and a guide rod perpendicular to the support plate is provided on the support plate. One end of the guide rod passes through the lifting plate and is slidably connected to the lifting plate.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] This invention uses diagonal braces to support the upright plate, providing sufficient support for the upright. The upright plate is rotatably connected to the bottom horizontal plate, allowing it to rotate around the horizontal plate. This allows the inclination of the upright plate to change with rotation, further enabling the top plate on the upright plate to be angled. This facilitates the top plate to press against the sealing head, achieving rapid support of the sealing head. Additionally, telescopic rods are located at the four corners of the mounting plate. By adjusting the length of different telescopic rods, the angle of the top plate hinged to the telescopic rods can be adjusted, allowing the inclination angle of the top plate to quickly align with the sealing head, thus facilitating its pressing against the sealing head. This replaces the process of pouring concrete to fill the gaps in existing technologies, saving the time of waiting for the concrete to reach the required strength and effectively shortening the testing time.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0031] like Figures 1-4 As shown, a support device for a pipe hydrostatic test plug is provided, wherein the plug is disposed inside the pipe end, comprising:

[0032] The upright plate 1 has a mounting plate 2 on its front. Each of the four corners of the mounting plate 2 has a telescopic rod 3 that is perpendicular to the mounting plate 2. One end of the telescopic rod 3 is fixedly connected to the mounting plate 2.

[0033] The top plate 4 is hinged to the other end of the telescopic rod 3 on its back side, and its front side is used to press against the sealing head.

[0034] The diagonal brace 5 is hinged at one end to the back of the upright plate 1 and inserted into the ground at the other end; the length of the diagonal brace 5 is adjustable.

[0035] A horizontal plate 6 is set at the bottom of the vertical plate 1, and the vertical plate 1 and the horizontal plate 6 are rotatably connected; the lower surface of the horizontal plate 6 is provided with several vertical fixing rods 609, which are used to insert into the ground.

[0036] In this invention, a sealing head is installed inside the pipe end to seal it. Since pipes are not usually perfectly horizontal, the sealing head typically has a certain degree of inclination. Several fixing rods 609 are provided on the lower surface of the horizontal plate 6, which are inserted into the ground to fix the position of the horizontal plate 6. The vertical plate 1 is rotatably connected to the horizontal plate 6, allowing it to maintain a fixed inclination under the support of the diagonal brace 5, enabling it to be initially parallel to the end face of the sealing head. Then, by adjusting the length of the telescopic rods 3 at different positions on the mounting plate 2, the inclination of the top plate 4, hinged to the telescopic rods 3, changes accordingly. With the vertical plate 1 initially parallel to the end face of the sealing head, the inclination of the top plate 4 is finely adjusted, allowing it to quickly align with the sealing head. This replaces the existing process of pouring concrete to fill gaps, eliminating the waiting time for the concrete to reach the required strength, effectively shortening the test duration, and accelerating the pipeline water pressure test.

[0037] In a preferred embodiment, the diagonal brace 5 includes a sleeve section 501, the top of which is hinged to the upright plate 1, and a rotating sleeve 502 coaxial with the sleeve section 501 is rotatably provided at the bottom. The rotating sleeve 502 is provided with internal threads. It also includes a screw 503, which is threadedly engaged with the rotating sleeve 502. The top of the screw 503 is inserted into the sleeve section 501, and the bottom is provided with a fork 504 for inserting into the ground.

[0038] This embodiment provides a feasible structure for the diagonal brace 5, specifically, as follows: Figure 5 As shown, the diagonal brace 5 includes a sleeve section 501 and a rotating sleeve 502 rotatably disposed at the bottom of the sleeve section 501. The rotating sleeve 502 is provided with an internal thread. It also includes a screw 503 that is threadedly engaged with the rotating sleeve 502. The top of the screw 503 is inserted into the sleeve section 501, so that when the rotating sleeve 502 is rotated, the length of the part of the screw 503 located outside the sleeve section 501 can be adjusted, thereby achieving the purpose of adjusting the length of the diagonal brace 5. In conjunction with the fork 504 for inserting into the ground, the diagonal brace 5 can change the tilt angle of the upright plate 1 by adjusting its length, so that the upright plate 1 can initially be parallel to the end face of the sealing head.

[0039] As a further embodiment, the rotating sleeve 502 is annular, with a connecting groove 505 on its upper end face. The cross-sectional shape of the connecting groove 505 is an inverted T-shape. The bottom of the sleeve section 501 matches the shape of the connecting groove 505.

[0040] This embodiment provides an optional connection method between the rotating sleeve 502 and the sleeve section 501. Specifically, as follows: Figure 5As shown, the rotating sleeve 502 is annular, with a connecting groove 505 recessed downwards at its upper end for inserting the sleeve section 501. The cross-sectional shape of the connecting groove 505 is an inverted T-shape, meaning that the bottom of the connecting groove 505 extends to both sides with an extended space perpendicular to the groove body. At the same time, the bottom of the sleeve section 501 matches the shape of the connecting groove 505, meaning that the bottom of the sleeve section 501 is provided with a limiting plate that matches the shape of the extended space extending outwards from the connecting groove 505. The limiting plate prevents the rotating sleeve 502 from separating from the sleeve section 501, while not hindering the rotation of the rotating sleeve 502 and the sleeve section 501.

[0041] In a preferred embodiment, the mounting plate 2 is also provided with a support rod 201, which is connected to the ball joint connector 202 and connected to the middle of the top plate 4 through the ball joint connector 202.

[0042] In this embodiment, as Figure 4 As shown, the support rod 201 and ball connector 202 are provided to distribute the supporting force during support. Because the water pressure test seal has high strength, if only the telescopic rod 3 is used for support, all the force would be applied to the telescopic rod 3, which would damage its structure over time and affect the equipment's lifespan. The support rod 201 is hinged to the top plate 4. The telescopic adjustment of the telescopic rod 3 only involves a slight angle adjustment of the top plate 4 via the ball connector 202 on the telescopic rod 3, ensuring a tight fit with the sealing area and guaranteeing the sealing effect. It should be noted that the telescopic rod 3 in this invention is a telescopic structure with its own power source; a hydraulic push rod can be selected.

[0043] In a preferred embodiment, a base 601 is provided on each side of the horizontal plate 6, and a rotating bearing is provided inside the base 601; a rotating shaft 602 is provided on each of the two opposite sides of the vertical plate 1, and the two rotating shafts 602 are respectively inserted into the two rotating bearings and fixed, and the vertical plate 1 rotates around the rotating shaft 602.

[0044] In this embodiment, a specific connection relationship between the vertical plate 1 and the horizontal plate 6 is provided to achieve the purpose of rotatable connection between the vertical plate 1 and the horizontal plate 6, wherein, as shown... Figures 1-4 As shown, a base 601 is provided on each side of the horizontal plate 6. A rotating bearing is provided in the base 601 for connecting the vertical plate 1. The two rotating bearings are axially collinear. A rotating shaft 602 is provided on the two opposite sides of the vertical plate 1 adjacent to the side where the mounting plate 2 is located. When the two ends of the rotating shaft 602 are inserted into the rotating bearings in the two bases 601 and fixed, the vertical plate 1 can rotate about the direction of the line connecting the two bases 601, that is, the radial direction of the rotating shaft 602, so as to realize the rotational connection between the vertical plate 1 and the horizontal plate 6. In conjunction with the extension and retraction of the diagonal brace 5, the initial adjustment of the tilt angle of the vertical plate 1 can be realized.

[0045] In a preferred embodiment, the horizontal plate 6 is provided with a lifting push rod 603 on the outer side of the two bases 601 respectively. The top output end of the lifting push rod 603 is provided with a long strip-shaped lifting plate 604. The lower surface of both ends of the lifting plate 604 is provided with a mounting rod 605 perpendicular to the lifting plate 604. The bottom of the mounting rod 605 is provided with a pulley 606, which is used to support the ground.

[0046] This embodiment provides a lifting push rod 603 mounted on a horizontal plate 6, such as Figures 1-4 As shown, the lifting push rod 603 is located on the horizontal plate 6 outside the base 601. A lifting plate 604 is provided at the top of the lifting push rod 603, and the lifting plate 604 is elongated. A mounting rod 605 perpendicular to the lifting plate 604 is provided on the lower surface of each end of the lifting plate 604. When the device supports the sealing head on the top plate 4, the length of the lifting push rod 603 is extended until the horizontal plate 6 contacts the ground, and the lifting push rod 603 continues to extend at least one fixed insertion rod 609. At this time, by applying external force, the fixed insertion rod 605 on the lower surface of the horizontal plate 6 is secured. The fixed insertion rod 609 is driven into the ground to fix the position of the horizontal plate 6, providing support and positioning. When the device needs to be adjusted, the length of the lifting push rod 603 is shortened. The retraction of the lifting push rod 603 allows the pulley block 606 at the bottom of the mounting rod 605 to support the ground. The retraction force of the lifting push rod 603 pulls the fixed insertion rod 609 out of the soil and lifts it off the ground. The pulley block 606 can then be used to move the device to the next working position. In this embodiment, the lifting push rod 603 can be either a hydraulic push rod or an electric push rod.

[0047] As a further embodiment, a support plate 607 is also provided on the side wall of the horizontal plate 6. A guide rod 608 perpendicular to the support plate 607 is provided on the support plate 607. One end of the guide rod 608 passes through the lifting plate 604 and is slidably connected to the lifting plate 604.

[0048] This embodiment provides a structure for limiting the guide rod 608, specifically, as follows: Figures 1-4 As shown, a support plate 607 is provided on the side wall of the horizontal plate 6, which serves as the installation position for the guide rod 608. One end of the guide rod 608 passes through the lifting plate 604 and is slidably connected to the lifting plate 604, so that the lifting plate 604 always moves along the axial direction of the guide rod 608 during the extension and retraction of the lifting push rod 603, thus preventing the lifting direction of the lifting plate 604 from deviating.

[0049] In addition, the upright plate 1 is provided with several reinforcing rods to enhance its strength, and the mounting plate 2 is fixed to the reinforcing rods. The lifting push rod 603 is also provided with mounting brackets on both sides, which are fixed to the horizontal plate 6 and used to position the lifting push rod 603; the top of the lifting push rod 603 is connected to the lifting plate 604 through a connecting sleeve sleeved on the outside of the lifting plate 604.

[0050] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.

[0051] In the description of this utility model, the terms "center", "upper", "lower", "horizontal", "inner", "outer", etc., are used only to indicate the orientation or positional relationship for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
