Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, specifically to a guiding and positioning device for pipeline installation. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gas, liquid, or fluids containing solid particles. In pipeline installation projects, the precise guidance and positioning of the pipeline is crucial.

[0003] Utility model patent CN220379035U discloses a guiding device for pipe installation. This device includes a fixed base plate, a support rod on the outer surface of one end of the base plate, a threaded adjusting rod in the middle of the support rod, a guide ring on the outer surface of one end of the threaded adjusting rod, an adjusting shaft between the threaded adjusting rod and the guide ring, a limiting screw on the outer wall of the adjusting shaft, a ball seat on the inner wall of the guide ring, a rolling ball in the middle of the ball seat, and a fixing screw in the middle of the fixed base plate. This guiding device for pipe installation, through the support rod, provides support for the guide ring during use. The height of the guide ring can be adjusted by rotating the threaded adjusting rod. The adjusting shaft allows for easy adjustment of the guide ring's angle, facilitating pipe guidance. The limiting screw locks the adjusting shaft. The rolling ball conforms to the surface of the pipe, guiding it. While the rubber material of the rolling ball inevitably causes some damage to the pipe during use, the device offers high guiding efficiency.

[0004] The guide device for pipe installation allows the pipe to sway and shake even after passing through it during installation, causing the pipe to tilt and affecting its installation position. Furthermore, this guide device is difficult to use to guide pipes of different diameters. Therefore, we propose a guide and positioning device for pipe installation. Utility Model Content

[0005] The purpose of this invention is to provide a guiding and positioning device for pipeline installation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pipeline installation guide and positioning device includes a pair of guide and positioning mechanisms and a connecting structure connecting the two guide and positioning mechanisms, wherein the guide and positioning mechanism includes a fixed base and a movable seat;

[0008] A fixed upright plate is fixed to the left edge of the top surface of the fixed base, and a fixed clamping seat is fixed to the right end of the top of the fixed upright plate. Several first rollers are rotatably connected to the fixed clamping seat. A protrusion is fixed to the top surface of the fixed base, and a pair of guide rods are fixed to the right end of the protrusion. The guide rods pass through the movable seat and are slidably connected to the movable seat.

[0009] A movable upright plate is fixed to the top of the movable seat, and a movable clamping seat is fixed to the left side of the top of the movable upright plate. The pipe is clamped between the fixed clamping seat and the movable clamping seat. The movable clamping seat has an arc-shaped plate structure. Several second rollers are rotatably connected to the movable clamping seat. The movable seat is penetrated by a threaded rod. The end of the threaded rod is rotatably connected to the protrusion. A threaded sleeve is sleeved on the outside of the threaded rod and threadedly connected to it. The threaded sleeve is fixedly connected to the movable seat.

[0010] The connecting structure includes a connecting plate and a pair of protruding rods that extend laterally through the connecting plate. The bottom end of the fixed base has a pair of parallel sleeve holes. The protruding rods are inserted into the sleeve holes, allowing the fixed base to move along the protruding rods.

[0011] Preferably, the fixed clamping seat has an arc-shaped plate structure that protrudes to the left, and the fixed upright plate is fixedly connected to the fixed clamping seat by a horizontal plate. The maximum outline of several first rollers protrudes from the inner wall of the fixed clamping seat, and the rolling direction of the first rollers at the contact point with the pipe is parallel to the axial direction of the pipe.

[0012] This feature allows the pipe to be held against the surface of the first roller when clamped, enabling the pipe to move along its axial direction as the first roller rotates.

[0013] Preferably, the movable clamping seat and the fixed clamping seat have the same shape on the guide positioning mechanism, and the movable clamping seat and the fixed clamping seat are symmetrical on the guide positioning mechanism;

[0014] This configuration allows the pipe to be held between the fixed clamp and the movable clamp when clamped. When the pipe is clamped by the two guide positioning mechanisms, the radial movement of the pipe is positioned while the pipe can move axially under the rotation of the first and second rollers.

[0015] Preferably, a transverse mounting hole is provided at the middle position of the movable seat, and the screw sleeve is fitted and fixed in the mounting hole;

[0016] Preferably, a convex shaft is fixed to the end of the threaded rod, the convex shaft passes through the convex seat and a baffle is fixed to the end, and the convex shaft can rotate axially in the convex seat;

[0017] Preferably, a lever is fixed at the beginning of the threaded rod.

[0018] In these three settings, the end of the threaded rod is restricted to the boss by the cam shaft and the baffle. By rotating the lever, the lever can drive the threaded rod to rotate on the boss, while preventing the threaded rod from disengaging from the boss.

[0019] Preferably, a pair of through guide holes are provided on the right end face of the movable seat, the size of the guide holes is adapted to the size of the guide rod, and the guide rod is inserted into the guide holes;

[0020] In this setup, the guide holes guide the movement of the guide rods. By cooperating with the two guide rods and the two guide holes, the movable seat can only move along the direction of the guide rods. By controlling the movable seat to move away from or closer to the fixed plate, the distance between the fixed clamping seat and the movable clamping seat can be controlled.

[0021] Preferably, a pair of shank bolts are threaded to the front edge of the top surface of the fixed base. The threaded portion of the shank bolts extends into the sleeve hole and is threaded to the fixed base. The end of the threaded shank of the shank bolt abuts against the surface of the protruding rod.

[0022] In this setup, by abutting the threaded portion of the shank bolt against the surface of the protruding rod, the protruding rod is fixed inside the sleeve hole when the shank bolt is tightened. When the shank bolt is loosened, the protruding rod can move along the sleeve hole, thereby adjusting the position of the guide positioning mechanism on the protruding rod. This allows for flexible adjustment of the distance between the two guide positioning mechanisms according to operational requirements.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The pipeline installation guide and positioning device connects two guide and positioning mechanisms through a connecting structure. Together with a fixed clamping seat and a movable clamping seat, it clamps the pipeline, effectively preventing instability such as shaking or shifting during installation. Simultaneously, the first roller on the fixed clamping seat and the second roller on the movable clamping seat roll synchronously as the pipeline moves. Utilizing the rolling characteristics of the rollers, the pipeline can be smoothly pushed to the predetermined position. While ensuring installation stability, it achieves precise guidance, ensuring the pipeline is installed strictly according to the preset path, thus improving the accuracy and reliability of pipeline installation.

[0025] 2. The movable seat in the device achieves movement adjustment through the threaded transmission of the threaded rod and the threaded sleeve. When dealing with pipes of different diameters, the operator only needs to rotate the threaded rod to move the movable clamping seat on the movable seat closer to or further away from the fixed clamping seat, flexibly changing the distance between the two. This adjustment method, which does not require replacing the overall structure or parts, allows the device to quickly adapt to diverse pipe installation needs, improves the versatility and practicality of the device, reduces installation costs, simplifies the installation process, and effectively improves work efficiency.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-7 The guide and positioning device for pipeline installation includes a pair of guide and positioning mechanisms 1 and a connecting structure 2 connected between the two guide and positioning mechanisms 1. The guide and positioning mechanism 1 includes a fixed base 11 and a movable seat 12.

[0038] like Figure 2 and Figure 3 As shown, in this utility model, a fixed upright plate 111 is fixed to the left edge of the top surface of the fixed base 11, and a fixed clamping seat 112 is fixed to the right end of the top of the fixed upright plate 111. A plurality of first rollers 113 are rotatably connected to the fixed clamping seat 112. The fixed clamping seat 112 has an arc-shaped plate structure protruding to the left. The fixed upright plate 111 and the fixed clamping seat 112 are fixedly connected by a horizontal plate. The maximum outline of the plurality of first rollers 113 protrudes from the inner wall of the fixed clamping seat 112, and the rolling direction of the contact point between the first rollers 113 and the pipe is parallel to the axial direction of the pipe. The fixed clamping seat 112, in conjunction with the first rollers 113, allows the first rollers 113 to roll along with the pipe when the guide positioning mechanism 1 clamps the pipe and moves the pipe along the axial direction, converting sliding friction into rolling friction and reducing frictional resistance during pipe installation.

[0039] like Figure 3 and Figure 4 As shown, specifically, a protrusion 114 is fixed on the top surface of the fixed base 11. A pair of guide rods 115 are fixed to the right end of the protrusion 114. A pair of through guide holes 126 are opened on the right end face of the movable seat 12. The size of the guide holes 126 matches the size of the guide rods 115. The guide rods 115 are inserted into the guide holes 126, passing through the movable seat 12 and slidingly connected to it. Through the cooperation of the guide rods 115 and the guide holes 126, precise sliding guidance is provided for the movable seat 12, allowing it to move stably along the guide rods 115, facilitating the adjustment of the clamping force and position on the pipe.

[0040] like Figure 4 and Figure 5As shown, furthermore, a movable upright plate 121 is fixed to the top of the movable seat 12, and a movable clamping seat 122 is fixed to the left side of the top of the movable upright plate 121. The pipe is clamped between the fixed clamping seat 112 and the movable clamping seat 122. The movable clamping seat 122 has an arc-shaped plate structure, and several second rollers 123 are rotatably connected to the movable clamping seat 122. The movable clamping seat 122 has the same shape as the fixed clamping seat 112 on the guide positioning mechanism 1, and the movable clamping seat 122 and the fixed clamping seat 112 are symmetrical in the guide positioning mechanism 1. By symmetrically cooperating the movable clamping seat 122 and the fixed clamping seat 112, the pipe is clamped from both sides by the first roller 113 and the second roller 123 respectively, which can effectively prevent the pipe from shifting during installation and ensure the accuracy of the pipe installation position.

[0041] like Figure 4 and Figure 5 As shown, the movable seat 12 is penetrated by a threaded rod 125, the end of which is rotatably connected to a boss 114. A threaded sleeve 1251 is fitted and threadedly connected to the outer side of the threaded rod 125. A transverse mounting hole 124 is provided at the middle of the movable seat 12, and the threaded sleeve 1251 is fitted and fixed in the mounting hole 124. Through the threaded transmission structure of the threaded rod 125 and the threaded sleeve 1251, the movement of the movable seat 12 can be precisely controlled by rotating the threaded rod 125, thereby flexibly adjusting the distance between the movable clamping seat 122 and the fixed clamping seat 112, so that the movable clamping seat 122 and the fixed clamping seat 112 can clamp pipes of different diameters.

[0042] like Figure 4 and Figure 6 As shown, it is worth noting that a convex shaft 1252 is fixed to the end of the threaded rod 125. The convex shaft 1252 passes through the boss 114 and a baffle 1253 is fixed to its end. The convex shaft 1252 can rotate axially within the boss 114. A lever 1254 is fixed to the beginning of the threaded rod 125. The convex shaft 1252 and the baffle 1253 restrict the axial movement of the threaded rod 125, ensuring its stable rotation while preventing the threaded rod 125 from coming out of the boss 114. The lever 1254 allows the operator to manually rotate the threaded rod 125, improving operational convenience.

[0043] like Figure 2 and Figure 7As shown, the connecting structure 2 further includes a connecting plate 21 and a pair of transversely penetrating protruding rods 22. A pair of parallel sleeve holes 116 are provided at the bottom end of the fixed base 11. The protruding rods 22 are inserted into the sleeve holes 116, allowing the fixed base 11 to move along the protruding rods 22. A pair of shank bolts 117 are threadedly connected to the front edge of the top surface of the fixed base 11. The threaded portion of the shank bolts 117 extends into the sleeve holes 116 and is threadedly connected to the fixed base 11. The threaded end of the shank bolts 117 abuts against the surface of the protruding rods 22. The connecting structure 2 realizes the connection and relative movement between the two guide positioning mechanisms 1. The shank bolts 117 can fix the position of the fixed base 11 on the protruding rods 22 by pressing against them, facilitating the adjustment of the distance between the two guide positioning mechanisms 1 according to actual installation requirements. This allows operators to easily adjust the spacing between the two guide positioning mechanisms 1 according to the length of the pipeline.

[0044] In this embodiment, the pipe installation guide and positioning device is used by first connecting two guide and positioning mechanisms 1 by inserting the protruding rod 22 of the connecting structure 2 into the sleeve hole 116 of the fixed base 11. After adjusting the distance between the two guide and positioning mechanisms 1 according to the pipe installation requirements, the shank bolt 117 is tightened so that the threaded part of the shank bolt 117 abuts against the surface of the protruding rod 22, thus fixing the positions of the two guide and positioning mechanisms 1 on the connecting structure 2. Then, the pipe is placed between the fixed clamping seat 112 and the movable clamping seat 122. At this time, the operator rotates the handle 1254 of the threaded rod 125 to rotate the threaded rod 125. Under the action of the thread... The screw sleeve 1251 will drive the movable seat 12 to move along the guide rod 115, thereby adjusting the distance between the movable clamping seat 122 and the fixed clamping seat 112 until the first roller 113 and the second roller 123 firmly clamp the pipe. At this time, the pipe is clamped on the guide positioning mechanism 1. Finally, after both guide positioning mechanisms 1 have clamped the pipe, the pipe is pushed along the axial direction of the pipe. At this time, by using the first roller 113 and the second roller 123 to convert sliding friction into rolling friction, the pipe can move along the axial direction. The pipe is clamped and positioned while being guided by the two guide positioning mechanisms 1, thereby assisting in the precise installation of the pipe.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
