Description

Technical Field

[0001] This utility model relates to the field of municipal engineering, specifically to a tooling for installing large-diameter pipes in confined spaces. Background Technology

[0002] Currently, PE water supply pipes are widely used in municipal water supply pipeline installation. Moreover, most municipal pipelines are large-diameter pipes, generally between 110 and 500 mm. When welding large-diameter PE water supply pipes, hydraulic hot melt welding machines are often used. Since the length of PE water supply pipes is between 6 and 12 meters, in the past, installers would find bricks and tiles on site to support the PE pipes in order to achieve the required welding effect. This construction method not only causes damage to the pipes due to friction from the bricks and tiles, but also occupies unnecessary manpower, brings many inconveniences to the construction, and increases costs. To solve the above problems, after searching, Chinese patent with publication number CN217476608U was found, which discloses a PE pipe roller support bracket for easy disassembly. The document includes a welded U-shaped steel bracket, and square seat pads are threadedly connected to the four corners of the welded U-shaped steel bracket by M20 height adjustment screws. An angle iron is fixedly connected to the inner bottom wall of the welded U-shaped steel bracket, and bidirectional rollers are rotatably connected to both sides of the angle iron by bearings. Although the above-mentioned device overcomes the problem of manual operation of large hot-melt PE pipes, in actual use, the pipe installation fixtures are mostly designed for open spaces. When working in narrow spaces, it is impossible to adjust the X / Y axis of the pipes being operated, which increases the difficulty of docking two sets of pipes that need to be connected due to the weight of the pipes.

An X-axis adjustment mechanism is installed at the bottom of the pipe mounting frame, and a Y-axis adjustment mechanism is provided at the bottom of the X-axis adjustment mechanism. A support frame is provided on the pipe mounting frame, and a center seat is installed at the bottom of the support frame. Roller A and roller B are respectively installed on the center seat, and the rotating shafts at the ends of roller A and roller B are movably connected to the upper side inside the support frame.

[0005] Furthermore, the support frame is U-shaped, and the rollers A and B inside the support frame are distributed in a V-shape, with rubber pads provided on the outer circumference of both rollers A and B.

[0006] Furthermore, the X-axis adjustment mechanism includes a connecting seat, a limiting frame, a screw, a guide column, and an operating wheel. The connecting seat is installed at the bottom of the support frame and is movably connected inside the limiting frame.

[0008] Furthermore, an operating wheel is installed on the outer side of the limiting frame, and a screw is connected to the end of the operating wheel. Multiple sets of force-bearing blocks are equidistantly arranged on the outer circumference of the operating wheel; the bottom of the X-axis adjustment mechanism is supported by the Y-axis adjustment mechanism.

[0009] Furthermore, the Y-axis adjustment mechanism includes a support foot, a fixing stud, a support frame, an adjustment channel, a fixing nut, and a stabilizing seat. The support foot is installed at the bottom of the limiting frame, and the support frame is installed at the bottom of the support foot. At the same time, the stabilizing seat is fixedly connected to the bottom of the support frame. The stabilizing seat is in the shape of an isosceles trapezoid.

Detailed Implementation

[0014] Please see Figure 1-5 This utility model provides a large-diameter pipe installation fixture in a confined space, including a pipe mounting frame 100. An X-axis adjustment mechanism 200 is installed at the bottom of the pipe mounting frame 100, and a Y-axis adjustment mechanism 300 is provided at the bottom of the X-axis adjustment mechanism 200. A support frame 11 is provided on the pipe mounting frame 100, and a center seat 12 is installed at the bottom of the support frame 11. Roller A13 and roller B14 are respectively installed on the center seat 12, and the rotating shafts at the ends of roller A13 and roller B14 are movably connected to the upper side inside the support frame 11.

[0015] Working Principle: When connecting large-diameter pipes in a confined space, the bottom of the large-diameter pipe is supported by this device. Rollers A13 and B14 are arranged in a "V" shape, and rubber pads are provided on the outer circumference of both rollers A13 and B14. This supports the end of the large-diameter pipe. The pipe can be adjusted along the X-axis using the X-axis adjustment mechanism 200, and along the Y-axis using the Y-axis adjustment mechanism 300. The position of the target pipe can be adjusted as needed, allowing for quick and accurate connection of two sets of pipes, reducing the difficulty of pipe connection.

[0016] In a preferred embodiment, the support frame 11 is U-shaped, and the rollers A13 and B14 inside the support frame 11 are distributed in a V-shape. Rubber pads are provided on the outer circumference of both rollers A13 and B14.

[0017] In a preferred embodiment, the X-axis adjustment mechanism 200 includes a connecting seat 21, a limiting frame 22, a screw 23, a guide post 24, and an operating wheel 25. The connecting seat 21 is installed at the bottom of the support frame 11 and is movably connected inside the limiting frame 22.

[0018] The limiting frame 22 is equipped with a screw 23 and a guide post 24. The screw 23 is installed inside the connecting seat 21. Guide holes are opened on both sides of the connecting seat 21, and the guide post 24 is inserted into the guide hole.

[0019] An operating wheel 25 is installed on the outer side of the limiting frame 22, and a screw 23 is connected to the end of the operating wheel 25. Multiple sets of force blocks are equidistantly arranged on the outer circumference of the operating wheel 25. The bottom of the X-axis adjustment mechanism 200 is supported by the Y-axis adjustment mechanism 300.

[0020] like Figure 1-4 As shown: The working method of the X-axis adjustment mechanism 200 is as follows: the operating wheel 25 is rotated, and the operating wheel 25 drives the screw 23 screwed inside the connecting seat 21 to rotate, so that the connecting seat 21 can move laterally inside the limit frame 22, thereby achieving the purpose of adjusting the lateral position of the pipe mounting bracket 100.

[0021] In a preferred embodiment, the Y-axis adjustment mechanism 300 includes a support foot 31, a fixing stud 32, a support frame 33, an adjustment channel 34, a fixing nut 35, and a stabilizing seat 36. The support foot 31 is installed at the bottom of the limiting frame 22, and the support frame 33 is installed at the bottom of the support foot 31. At the same time, the stabilizing seat 36 is fixedly connected to the bottom of the support frame 33. The stabilizing seat 36 is in the shape of an isosceles trapezoid.

[0022] The cross-section of the support frame 33 is U-shaped, and two sets of adjustment channels 34 are opened on the side wall of the support frame 33. At the same time, the adjustment channels 34 are filled with fixing studs 32, and fixing nuts 35 are screwed onto the fixing studs 32. The ends of the fixing studs 32 are fixed to the support feet 31.

[0023] like Figure 1 As shown: The working method of the Y-axis adjustment mechanism 300 is as follows: hold the pipe mounting bracket 100 by hand, insert the bottom of the support foot 31 into the inside of the support frame 33, and when the height of the pipe mounting bracket 100 is adjusted, use a wrench to tighten the fixing nut 35 so that the fixing nut 35 is screwed onto the fixing stud 32, thus completing the height adjustment of the pipe mounting bracket 100.

[0024] like Figure 1-4As shown: The device supports the bottom and ends of a large-diameter pipe using rollers A13 and B14 arranged in a "V" shape. The "V" shape conforms to the circumference of the large-diameter pipe, forming a stable support angle, effectively preventing the pipe from swaying or shifting in confined spaces, ensuring support reliability. Simultaneously, rubber pads are installed on the outer walls of rollers A13 and B14, allowing direct contact with the pipe's outer wall. This increases friction between the rollers and the pipe, further enhancing support stability, and prevents scratches and damage caused by direct friction between the metal rollers and the pipe's outer wall, thus protecting the pipe. The device is flexible and adaptable to different docking positions. The X-axis adjustment mechanism 200 allows for flexible adjustment of the pipe along the X-axis, and the Y-axis adjustment mechanism 300 allows for adjustment along the Y-axis. Together, these mechanisms enable fine-tuning of the pipe's position in two dimensions. Within confined spaces, workers can adjust the position of the target pipe using two adjustment mechanisms based on its actual location, eliminating the need for frequent movement of the overall support structure. This significantly improves the flexibility and accuracy of position adjustment, solving the problem of difficult pipe positioning within confined spaces. It also reduces docking difficulty and improves operational efficiency and quality. Relying on the stability of the "V"-shaped support and the adjustment capabilities of the X-axis adjustment mechanism 200 and the Y-axis adjustment mechanism 300, workers can quickly adjust the target pipe to a coaxial and aligned state without repeated attempts and calibrations, significantly reducing the operational difficulty of docking large-diameter pipes within confined spaces. Simultaneously, docking reduces deviations during pipe connection, ensuring the sealing and structural strength of subsequent connections, such as welding and flange connections. This improves docking efficiency and ensures the engineering quality of the pipe docking.
