Description

Technical Field

[0001] This utility model belongs to the field of pipeline welding technology, specifically relating to a large-diameter pipeline support roundness adjustment device. Background Technology

[0002] After welding, thin-walled, large-diameter rolled pipes will sink at the top under gravity due to the lack of support, forming an elliptical shape. During pipe alignment, the increased roundness deviation will make alignment difficult, reducing construction efficiency. During transportation, without internal support, the pipes will vibrate with the bumps of the vehicle; excessive vibration can cause the wire ropes or other bindings to loosen, posing a transportation safety hazard. Support devices typically use multiple support rods evenly arranged circumferentially, with fixed connections between them. This results in a large space requirement for the support device during recovery and storage, affecting its transportation and storage. Utility Model Content

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please refer to the following: Figures 1 to 3 The present invention provides a large-diameter pipe support roundness adjustment device. The large-diameter pipe support roundness adjustment device includes a connecting plate 1, a limiting block 2, an insert plate 3, a support rod 4, and a pressing assembly 5. The limiting block 2 is fixedly installed in the middle of the connecting plate 1, and multiple limiting surfaces are provided on the outer side of the limiting block 2, which are evenly arranged along the circumference of the limiting block 2. The number of insert plates 3 corresponds one-to-one with the limiting surfaces, and the insert plates 3 are fixedly installed on the connecting plate 1, with the insert plates 3 and the limiting surfaces arranged parallel to each other at intervals. One end of the support rod 4 abuts against the limiting surface, and the support rod 4 is provided with a slot that slides with the insert plate 3. The pressing assembly 5 is disposed between the connecting plate 1 and the support rod 4, and is used to press the support rod 4 onto the connecting plate 1.

[0027] The large-diameter pipe support roundness adjustment device provided in this embodiment, compared with the prior art, features a connecting plate 1 with a limiting block 2 fixedly installed in the middle of the connecting plate 1. The outer surface of the limiting block 2 is a regular polygonal structure. An insert plate 3 is also fixedly installed on the connecting plate 1, with the insert plate 3 and the outer limiting surface of the limiting block 2 arranged parallel to each other. A slot corresponding to the insert plate 3 is provided at one end of the support rod 4, allowing the support rod 4 to be placed on the connecting plate 1 and the insert plate 3 to be inserted into the slot of the support rod 4 during installation. When the support rod 4 is installed on the connecting plate 1, its end rests against the limiting surface. Finally, the clamping assembly 5 presses the support rod 4 firmly onto the connecting plate 1. After use, the clamping assembly 5 can be disassembled to remove the support rod 4. This facilitates the collection and storage of multiple support rods 4 and facilitates subsequent transportation.

[0028] Specifically, in this embodiment, when multiple support rods 4 are installed on the connecting plate 1, the included angle between two adjacent support rods 4 is 45°.

[0029] In some embodiments, the clamping component 5 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 The clamping assembly 5 includes a pressure plate 51 and a tightening member 52. One side of the pressure plate 51 has a protruding annular protrusion for pressing the support rod 4 against the connecting plate 1. The tightening member 52 is threadedly connected to the limiting block 2 and extends through the pressure plate 51. The annular protrusion on one side of the pressure plate 51 has an inner diameter larger than the maximum size of the limiting block 2. The tightening member 52 is a bolt. The connecting plate 1 has a protrusion for mounting the tightening member 52. The tightening member 52 extends through the pressure plate 51 and is threadedly connected to the protrusion. When the pressure plate 51 is mounted on the connecting plate 1, the annular protrusion preferentially abuts against the side wall of the support rod 4, thereby pressing the support rod 4 against the connecting plate 1 and limiting the insert plate 3 inside the slot of the support rod 4.

[0030] In some embodiments, the pressure plate 51 described above can be as follows: Figure 2 The structure shown. See also Figure 2 The pressure plate 51 has a guide sleeve 511 protruding from one side of the annular protrusion, and the limiting block 2 also has a guide hole that slides with the guide sleeve 511. The guide sleeve 511 protrudes from one side of the pressure plate 51, and its length is greater than the length of the annular protrusion. The limiting block 2 has a guide hole in its middle that slides with the guide sleeve 511. When the pressure plate 51 is installed on the limiting block 2, the guide sleeve 511 slides into the guide hole first. This helps to position the pressure plate 51. When the pressure plate 51 is installed on the limiting block 2, the annular protrusion on the pressure plate 51 can simultaneously act on the ends of multiple support rods 4.

[0031] In some embodiments, the aforementioned limiting block 2 can be adopted as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3The limiting block 2 has multiple limiting surfaces arranged in pairs parallel to each other. The ends of the support rods 4, which abut against two parallel limiting surfaces, are respectively fitted with fixed supports 6 and movable supports 7. The movable supports 7 are equipped with crossbars 71 whose position can be adjusted along the length of the support rods 4. The limiting block 2 has multiple sets of limiting surfaces arranged in pairs parallel to each other. When the support rods 4 are installed on the connecting plate 1, the ends of two support rods 4 arranged in the same length direction are respectively fitted with fixed supports 6 and movable supports 7. When installed inside the pipe, the fixed supports 6 on one side can be used for positioning, and then the movable supports 7 on the other side can be used for fine-tuning, so that the two support rods 4 in each set located on the same straight line can effectively abut against the inner wall of the pipe. This is convenient to operate and allows for easy adjustment of the support rods 4 against the inner wall of the pipe.

[0032] Specifically, in this embodiment, the movable support 7 includes a crossbar 71 for abutting against the inner wall of the pipe, and the length direction of the crossbar 71 is arranged along the axial direction of the pipe. By adjusting the relative distance between the crossbar 71 and the support rod 4, the crossbar 71 can effectively abut against the inner wall of the pipe.

[0033] In some embodiments, the activity support 7 described above can be adopted as follows: Figure 3 The structure shown. See also Figure 3 The movable support 7 includes an insert rod 72 inserted into the support rod 4 and an adjusting rod 73 whose two ends are threadedly connected to the crossbar 71 and the insert rod 72, respectively. The threads at both ends of the adjusting rod 73 have opposite directions of rotation. A nut threaded to one end of the adjusting rod 73 is fixedly installed at the end of the support rod 4, and a nut threaded to the other end of the adjusting rod 73 is fixedly installed at the middle of the crossbar 71. The two ends of the adjusting rod 73 are threadedly connected to two nuts, and the two nuts have opposite directions of rotation. Thus, the distance between the crossbar 71 and the end of the support rod 4 can be adjusted by rotating the adjusting rod 73. The structure is simple and facilitates the adjustment of the position of the crossbar 71.

[0034] In some embodiments, the fixed support 6 and the movable support 7 described above can be adopted as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 The fixed support 6 and the movable support 7 on the support rod 4 have the freedom to adjust their positions along the length of the support rod 4. Both the fixed support 6 and the movable support 7 can be adjusted along the length of the support rod 4. In use, the positions of the movable support 7 and the fixed support 6 on the support rod 4 can be adjusted according to the inner diameter of the pipe, thus allowing for a coarse adjustment of the distance between the movable support 7 and the fixed support 6. Then, by placing the device inside the pipe so that the fixed support 6 is supported on the inner wall of the pipe, fine adjustments can be made using the movable support 7. This method is suitable for supporting pipes of different inner diameters.

[0035] Specifically, in this embodiment, multiple movable supports 7 are located on support rods 4 at the semicircle of the limiting block 2, and multiple fixed supports 6 are located on support rods 4 at the other semicircle of the limiting block 2.

[0036] In some embodiments, the activity support 7 described above can be adopted as follows: Figure 3 The structure shown. See also Figure 3 The support rod 4 has multiple through holes on its side wall, spaced apart along its length. A locating pin 8 is threaded onto the insertion rod 72, passing through each through hole. The insertion rod 72 is slidably disposed inside the support rod 4. The support rod 4 is made of square tubing. The insertion rod 72 is inserted into the end of the support rod 4. At least two threaded holes for mounting the locating pin 8 are provided on one side of the insertion rod 72. Multiple through holes corresponding to these threaded holes are provided on the side wall of the support rod 4. After the insertion rod 72 has been roughly adjusted, it can be inserted into the support rod 4, aligning the threaded holes on the insertion rod 72 with the through holes on the support rod 4. The locating pin 8 is then used to fix the insertion rod 72 into the support rod 4.

[0037] Specifically, in this embodiment, the fixed support 6 also includes a connecting rod with the same structure as the insertion rod 72, and a guide rod fixedly installed at the end of the connecting rod. The middle part of the guide rod is fixedly installed on the connecting rod, and the guide rod and the crossbar 71 have the same size.

[0038] In some embodiments, the locating pin 8 may be adopted as follows: Figure 3 See the structure shown. Figure 3 The locating pin 8 includes a threaded portion 82 that is threadedly connected to the insert rod 72 and a locating portion 81 that slides into the inner wall of the through hole. One end of the locating pin 8 is the threaded portion 82 that is threadedly connected to the insert rod 72, and the other end of the locating pin 8 is provided with the locating portion 81 that slides into the through hole. When the locating pin 8 is installed between the insert rod 72 and the support rod 4, the locating portion 81 is located inside the through hole and slides into the inner wall of the through hole. The locating portion 81 improves the stability of the connection between the support rod 4 and the insert rod 72, ensuring the stability of the relative position of the insert rod 72 and the support rod 4 during the support process.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
