Description

Technical Field

[0001] This utility model relates to the field of pipeline construction, and in particular to a pipeline docking clamp. Background Technology

[0002] Currently, the metallurgical, petrochemical, power construction, and large, medium and small industrial engineering projects involve numerous and complex process pipelines and energy medium pipelines. During construction, there are many pipeline joints, resulting in high personnel and machinery costs. Conventional pipeline connection methods are slow, affect construction progress, and cannot guarantee the quality of pipeline connection.

[0003] The construction of pipelines of all sizes plays a crucial role in the entire construction process. During construction, various problems can easily arise at the joints of different pipelines, such as substandard parallelism of pipe ends, uneven pipe ends, uneven joint gaps, severe bulging of the inner and outer pipe ends, and tapered joints. These issues cannot guarantee the quality of the pipe connection. If these problems are not detected during construction, after the project is put into operation, pipeline joint breaks, serious leaks, and other phenomena that directly affect production can easily occur, causing significant losses to the construction unit.

[0026] The specific embodiments of this utility model will now be described in more detail with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0027] Figure 1 This is a schematic diagram of a pipe docking clamp according to an embodiment of the present invention. Figure 2 yes Figure 1 Side view. Please refer to... Figure 1 and Figure 2 This utility model provides a pipe docking clamp, which includes multiple fastening components 3, a first pipe clamp 1, and a second pipe clamp 2.

[0028] The first pipe clamp 1 includes a first arc-shaped portion 11 and first connecting portions 13 located at both ends of the first arc-shaped portion 11. Multiple fastening components 3 are connected to the first arc-shaped portion 11, and a first clearance hole 12 is provided on the first arc-shaped portion 11 to allow space for welding operations. The second pipe clamp 2 includes a second arc-shaped portion 21 and second connecting portions 22 located at both ends of the second arc-shaped portion 21. Multiple fastening components 3 are connected to the second arc-shaped portion 21, and a second clearance hole 23 is provided on the second arc-shaped portion 21 to allow space for welding operations. The second connecting portions 22 correspond one-to-one with and connect to the first connecting portions 13, forming a space between the first arc-shaped portion 11 and the second arc-shaped portion 21 to clamp the pipe 5 to be connected. Fastening components 3 are used to press against the pipes 5 to be connected, thereby securing the pipes 5. Both pipes 5 to be connected are pressed against by the fastening components 3. For example, the fastening components 3 are divided into two groups, with each group pressing against one pipe 5 to be connected. Preferably, all fastening components 3 in each group are distributed on the same plane, and this plane is perpendicular to the axis of the pipes 5 to be connected. The first pipe clamp 1 and the second pipe clamp 2 can be made of a plate with a thickness of 8mm-12mm. The first clearance hole 12 and the second clearance hole 23 can both be strip holes, for example, with the long side of the strip hole perpendicular to the axis of the pipe to be connected.

[0029] The number of first connecting parts 13 is at least two, and they are symmetrically distributed at both ends of the first arc-shaped surface 11. Similarly, since the second connecting parts 22 correspond one-to-one with the first connecting parts 13, the number of second connecting parts 22 is also at least two, and they are symmetrically distributed at both ends of the second arc-shaped surface 21. In this embodiment, the number of first connecting parts 13 is four, with two first connecting parts 13 located on one side of the pipe 5 to be connected, and the other two first connecting parts 13 located on the other side of the pipe 5 to be connected. The distribution of the second connecting parts 22 is similar.

[0030] Furthermore, the pipe connection clamp includes a connecting bolt 41 and a fastening nut 42, and the second connecting part 22 is connected to the first connecting part 13 by the connecting bolt 41 and the fastening nut 42. For example, both the second connecting part 22 and the first connecting part 13 can be straight plates, and both the second connecting part 22 and the first connecting part 13 are provided with through holes for the connecting bolt 41 to be assembled.

[0031] Furthermore, the fastening component 3 includes nuts 31 and fastening bolts 32 that are threaded together. Multiple nuts 31 are fixedly connected to the first arcuate portion 11 and multiple nuts 31 are fixedly connected to the second arcuate portion 21. The thread of the fastening bolt 32 is used to press against the pipe 5 to be connected, and the pipe 5 can be tightened by rotating the fastening bolt 32. Preferably, both the first arcuate portion 11 and the second arcuate portion 21 are provided with multiple mounting holes, and a nut 31 is fixedly connected to each mounting hole. In other embodiments, the nuts 31 can also be fixed to the sides of the first arcuate portion 11 and the second arcuate portion 21, such as... Figure 2 and Figure 3 As shown. It is understandable that providing mounting holes to secure the nut 31 is more secure. In some embodiments, the fastening component 3 can be a stud, with the first arcuate portion 11 directly threaded into the stud and the second arcuate portion 21 directly threaded into the stud, pressing against the pipe to be connected by the stud.

[0032] Based on another aspect of this utility model, this utility model also provides a pipe connection method, which uses the pipe connection clamp as described above. The pipe connection method includes steps S1, S2, S3, S4, S5 and S6. Steps S1, S2, S3, S4, S5 and S6 will be described in detail below.

[0033] Step S1: Place the two pipes 5 to be connected in the mating position, so that the central axes of the two pipes 5 to be connected are on the same straight line.

[0034] Specifically, the two pipes to be connected (5) are raised 100mm-300mm and placed in a suitable alignment position using hoisting equipment. For example, based on the site layout requirements, sleepers or other supports are used to raise the two pipes to be connected (5) to a height of approximately 200mm. A crane or other hoisting tools are then used to initially place the two pipes to be connected (5) in a suitable alignment position, ensuring that the central axes of the two pipes are aligned in a straight line. The two pipes to be connected (5) are then effectively secured to prevent them from rolling or slipping.

[0035] Step S2: Place the pipe connection clamp onto the joint of the two pipes 5 to be connected, ensuring that the distance between the two pipes 5 is less than a preset value, and that the first clearance hole 12 and the second clearance hole 23 expose the joint of the two pipes 5. For example, the preset value is 2mm-4mm.

[0036] For example, firstly, the first pipe clamp 1 and the second pipe clamp 2 are placed on one pipe 5 to be connected. Then, a hand-operated hoist or other extendable tool is used to pull the other pipe 5 to be connected between the first pipe clamp 1 and the second pipe clamp 2, so that the gap between the two pipes 5 to be connected is within about 3mm, and the first clearance hole 12 and the second clearance hole 23 can expose the joint of the two pipes 5 to be connected, so as to facilitate subsequent welding of the joint.

[0037] Step S3: Connect the second connecting part 22 to the first connecting part 13 one by one and tighten them. That is, tighten the second connecting part 22 to the first connecting part 13 using connecting bolts 41 and fastening nuts 42.

[0038] Step S4: Adjust and tighten the two pipes 5 to be connected by multiple fastening components 3 to ensure that the two pipes 5 are properly connected.

[0039] Multiple fastening bolts 32 are used to hold the two pipes 5 to be connected together. The position of the two pipes 5 to be connected can be adjusted according to the parallelism of their cross-sections. Adjustments can be made in the up, down, left, and right directions until the gap between the two pipes 5 and all parameters affecting the connection quality meet the specifications.

[0040] Step S5: Perform partial welding on the two pipes 5 to be connected through the first clearance hole 12 and the second clearance hole 23.

[0041] For example, the two pipes 5 to be connected are spot welded together through the first clearance hole 12 and the second clearance hole 23.

[0042] Step S6: Remove the pipe docking clamp and continue circumferential welding of the two pipes 5 to be docked.

[0043] Understandably, when there are differences in the joints of the two pipes 5 to be connected, the two pipes 5 need to be adjusted before connection to ensure that the inner and outer diameters of the pipe walls at the joint are the same, thus guaranteeing the quality of the pipe joint.

[0044] The pipe connection method also includes fabricating a pipe connection fixture, such that the radii of the first arc-shaped surface 11 and the second arc-shaped surface 21 are both larger than the radius of the pipe 5 to be connected, and the sum of the central angles corresponding to the first arc-shaped surface 11 and the second arc-shaped surface 21 is not greater than 360°. Preferably, the radii of the first arc-shaped surface 11 and the second arc-shaped surface 21 are the same. For example, a steel plate with a thickness of 10 mm and a width of 200 mm is flame-bent with a bending radius 1.5 times the radius of the pipe to be connected to obtain the first arc-shaped surface 11 and the second arc-shaped surface 21. The sum of the arc lengths of the first arc-shaped surface 11 and the second arc-shaped surface 21 can be equivalent to the outer circumference of the pipe to be connected.

[0045] The steps for manufacturing the pipe connection clamp include: opening multiple mounting holes on the first arc-shaped surface 11 and the second arc-shaped surface 21, and welding a nut 31 into each mounting hole. For example, three mounting holes are opened on each of the first arc-shaped surface 11 and the second arc-shaped surface 21, and then the nuts 31 are riveted and welded into the mounting holes.

[0046] As configured above, the pipe-connecting clamp of this utility model holds the pipes using a first pipe clamp 1 and a second pipe clamp 2, and the positions of the two pipes 5 to be connected can be adjusted using multiple fastening components 3. Compared with traditional pipe-connecting methods, this utility model can save a lot of time, improve the efficiency of pipe connection, and achieve high-quality pipe connections. It significantly reduces the probability of defects such as pipe breakage and leakage at the connection points after the project is put into operation, ensuring project quality and the safety of subsequent production. Furthermore, this utility model is easy to construct and readily applicable on a large scale, making its application prospects very broad.
