Description

Technical Field

[0001] The invention relates to a steel pipe welding auxiliary device, in particular to a steel pipe segment interface assembly and groove gap adjustment device. Background Art

[0002] Large steel pipes are used in many steel structures. They are typically assembled on-site by butting and welding the pipe segments together. However, due to dimensional deviations during processing, deformation from collisions during transportation, and the heavy weight of the pipe segments themselves, the assembly and joint construction of the pipe segments is extremely difficult. It is also difficult to ensure that the groove gap between adjacent pipe segments meets the requirements after butting.

[0003] When constructing segmented steel pipe joints, the industry typically uses multiple L-shaped iron bars for point-by-point welding to temporarily secure the joints until they are complete. Existing construction techniques cannot guarantee the straightness of the assembled pipes, the dimensional tolerances of the joints, or the required groove clearances. Furthermore, the process is labor-intensive and inefficient. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a device for assembling and adjusting the groove gap of steel pipe segments. This device not only ensures the straightness of the assembled steel pipe and the allowable dimensional deviation of the assembled interface after assembly, and ensures that the groove gap at the assembled interface meets the requirements, but also reduces worker labor intensity, improves work efficiency, accelerates construction progress, and reduces project construction costs.

[0005] The device for assembling steel pipe segmented interfaces and adjusting groove gaps according to an embodiment of the present invention comprises:

[0006] The main adjustment frame can be detachably mounted outside the steel pipe segment;

[0007] Two secondary adjustment frames are located at both ends of the main adjustment frame and are coaxially arranged with the main adjustment frame. Both of the secondary adjustment frames can be detachably sleeved outside the steel pipe segment;

[0008] The adjustment mechanism is provided between the main adjustment frame and the secondary adjustment frame to adjust the distance between the main adjustment frame and the secondary adjustment frame.

[0009] The steel pipe segmented interface assembly and groove gap adjustment device according to the embodiment of the present invention has at least the following technical effects:

[0010] When it is necessary to adjust the gap between the grooves of the two adjacent steel pipe segments after the interface is assembled and butted, one of the secondary adjustment frames is inserted and fastened on the outer wall of one of the steel pipe segments, the other secondary adjustment frame is inserted and fastened on the outer wall of the other adjacent steel pipe segment, the main adjustment frame is inserted outside the interface of the two adjacent steel pipe segments, but the main adjustment frame is not fastened and installed, and then the gap between the grooves of the two steel pipe segments that are initially assembled and butted is observed to see whether it meets the requirements. When the groove gap at the assembled interface is larger than the design size, according to the actual situation, the adjustment mechanism between the main adjustment frame and one of the secondary adjustment frames is operated so that the main adjustment frame and the secondary adjustment frame can move toward each other, thereby driving the two adjacent steel pipe segments to move toward each other, thereby reducing the groove gap and making the groove gap meet the design requirements for facilitating welding. Correspondingly, when the groove gap at the assembled interface is smaller than the design size, according to the actual situation, the adjustment mechanism between the main adjustment frame and one of the secondary adjustment frames is operated so that the main adjustment frame and the secondary adjustment frame can move away from each other. When the groove gap reaches the design requirements, the main adjustment frame is fastened and installed outside the interface of the two adjacent steel pipe segments, thereby making the two steel pipe segments relatively fixed. Since the two secondary adjustment frames are coaxial with the main adjustment frame, the straightness of the two steel pipe segments and the allowable deviation of the size of the assembly interface can be guaranteed after the main adjustment frame is fastened. After that, the interface is welded to complete the splicing of the two adjacent steel pipe segments. The steel pipe segment interface assembly and groove gap adjustment device according to the embodiment of the present invention can not only ensure the straightness of the assembled steel pipe and the allowable deviation of the size of the assembly interface, and ensure that the groove gap at the assembly interface position meets the requirements, but also reduce the labor intensity of workers, improve work efficiency, promote construction progress, and reduce engineering construction costs.

[0030] Reference below Figures 1 to 3 A device for assembling steel pipe segmented interfaces and adjusting groove gaps according to an embodiment of the present invention is described.

[0031] According to the steel pipe segment interface assembly and groove gap adjustment device of the embodiment of the present invention, Figures 1 to 3 Shown, including:

[0032] The main adjustment frame 100 is detachably mounted on the outside of the steel pipe segment 600;

[0033] Two secondary adjustment frames 200 are located at both ends of the main adjustment frame 100 and are coaxially arranged with the main adjustment frame 100. Both secondary adjustment frames 200 can be detachably sleeved outside the steel pipe segment 600.

[0034] The adjustment mechanism 300 is disposed between the main adjustment frame 100 and the secondary adjustment frame 200 to adjust the distance between the main adjustment frame 100 and the secondary adjustment frame 200 .

[0035] In this embodiment, when it is necessary to adjust the gap between the grooves of the interface assembly and the butt joint of two adjacent steel pipe segments 600, one of the secondary adjustment frames 200 is inserted into and installed on the outer wall of one of the steel pipe segments 600, and the other secondary adjustment frame 200 is inserted into and installed on the outer wall of the other adjacent steel pipe segment 600. The main adjustment frame 100 is inserted outside the interface of the two adjacent steel pipe segments 600, but the main adjustment frame 100 is not tightened and installed. Then, it is observed whether the gap between the grooves of the two steel pipe segments 600 that are preliminarily assembled and butt jointed meets the requirements. When the groove gap at the assembled interface is larger than the designed size, according to the actual situation, the adjustment mechanism 300 between the main adjustment frame 100 and one of the secondary adjustment frames 200 is operated to enable the main adjustment frame 100 and the secondary adjustment frame 200 to move toward each other, thereby driving the two adjacent steel pipe segments 600 to move toward each other, thereby narrowing the groove gap and making the groove gap meet the design requirements, so as to facilitate welding. Correspondingly, when the groove gap at the assembly interface is smaller than the design size, the adjustment mechanism 300 between the main adjustment frame 100 and one of the secondary adjustment frames 200 is operated according to the actual situation to move the main adjustment frame 100 and the secondary adjustment frame 200 away from each other. When the groove gap meets the design requirements, the main adjustment frame 100 is fastened and installed outside the interface of two adjacent steel pipe segments 600, thereby fixing the two steel pipe segments 600 relatively. Since the two secondary adjustment frames 200 are coaxial with the main adjustment frame 100, the straightness of the two steel pipe segments 600 and the dimensional tolerance of the assembly interface can be guaranteed after the main adjustment frame 100 is fastened. After that, the interface is welded to complete the splicing of the two adjacent steel pipe segments 600. The steel pipe segmented interface assembly and groove gap adjustment device according to the embodiment of the present invention can not only ensure the straightness of the steel pipe after assembly and the allowable dimensional deviation of the assembly interface, and ensure that the groove gap at the assembly interface position meets the requirements, but also reduce the labor intensity of workers, improve work efficiency, promote construction progress, and reduce project construction costs.

[0036] It should be noted that the main adjustment frame 100 and the two secondary adjustment frames 200 can be detachably mounted on the outside of the steel pipe segment 600. That is, the main adjustment frame 100 and the two secondary adjustment frames 200 can be mounted on the outer wall of the steel pipe segment 600 and can be fastened to the outer wall of the steel pipe segment 600. When not in use, they can also be removed. Adjustment mechanisms 300 are provided at both ends of the main adjustment frame 100, making it more convenient to use. For example, if one adjustment mechanism 300 is inconvenient to operate due to operating environment or other reasons, the other adjustment mechanism 300 can be operated.

[0037] In some embodiments of the present invention, Figure 1 and Figure 3As shown, the adjustment mechanism 300 includes a plurality of adjustment screws 301 distributed in sequence along the circumference of the main adjustment frame 100. One end of the adjustment screw 301 is connected to the main adjustment frame 100, and a through hole is correspondingly provided on the secondary adjustment frame 200. The other end of the adjustment screw 301 passes through the through hole, and the adjustment screw 301 is threadedly connected to an adjustment nut 302 on both sides of the through hole. When it is necessary to adjust the gap between the grooves after the two adjacent steel pipe segments 600 are connected, the two adjustment nuts 302 on both sides of the adjustment screw 301 can be rotated, which is easy to operate. The plurality of adjustment screws 301 are distributed in sequence along the circumference of the main adjustment frame 100, so that the gap between the grooves after the two adjacent steel pipe segments 600 are connected can be evenly adjusted, making the adjustment more precise. Of course, the adjustment mechanism 300 can also be other mechanisms, such as a cylinder, an oil cylinder, etc. Taking the oil cylinder as an example, one end of the oil cylinder can be connected to the main adjustment frame 100 and the other end can be connected to the secondary adjustment frame 200, and then the adjustment can be performed by extending and retracting the oil cylinder.

[0038] In some embodiments of the present invention, the adjustment mechanism 300 includes a plurality of adjustment screws 301 distributed sequentially along the circumference of the main adjustment frame 100. One end of the adjustment screw 301 is connected to the secondary adjustment frame 200. The main adjustment frame 100 is provided with a corresponding through hole. The other end of the adjustment screw 301 passes through the through hole. The adjustment screw 301 is threadedly connected to an adjustment nut 302 on both sides of the through hole. When the gap between the grooves of two adjacent steel pipe segments 600 after docking is needed, the two adjustment nuts 302 on both sides of the adjustment screw 301 are simply rotated, which is convenient for operation. The plurality of adjustment screws 301 are distributed sequentially along the circumference of the main adjustment frame 100, so that the gap between the grooves of two adjacent steel pipe segments 600 after docking can be evenly adjusted, making the adjustment more precise. Of course, the adjustment mechanism 300 can also be other mechanisms, such as a cylinder, an oil cylinder, etc. Taking an oil cylinder as an example, one end of the oil cylinder can be connected to the main adjustment frame 100 and the other end can be connected to the secondary adjustment frame 200, and then the adjustment can be performed by extending and retracting the oil cylinder.

[0039] In some embodiments of the present invention, the length direction of the adjusting screw 301 is parallel to the axial direction of the main adjusting frame 100. This ensures that the through hole only moves relative to the adjusting screw 301 along the length direction of the adjusting screw 301, thereby preventing the through hole from interfering with the corresponding adjusting screw 301 and damaging the main adjusting frame 100 or the adjusting screw 301.

[0040] In some embodiments of the present invention, the inner wall of the secondary adjustment frame 200 is provided with anti-slip stripes. These stripes increase the friction between the inner wall of the secondary adjustment frame 200 and the outer wall of the steel pipe segment 600, thereby preventing relative sliding between the secondary adjustment frame 200 and the steel pipe segment 600 after the secondary adjustment frame 200 is securely mounted thereon. This allows for more precise adjustment of the groove gap at the interface. The anti-slip stripes may be inclined well-shaped, further increasing the friction between the inner wall of the secondary adjustment frame 200 and the outer wall of the steel pipe segment 600.

[0041] In some embodiments of the present invention, Figure 2 As shown, the main adjustment frame 100 includes a first half frame 101 and a second half frame 102. One end of the first half frame 101 is hinged to one end of the second half frame 102, and the other end of the first half frame 101 is detachably connected to the other end of the second half frame 102. The first half frame 101 and the second half frame 102 are both semicircular ring structures. The first half frame 101 and the second half frame 102 enclose and form the annular main adjustment frame 100. The first half frame 101 and the second half frame 102 are connected together to reduce the probability of losing the first half frame 101 and the second half frame 102. In addition, the operation is more convenient when installing and mounting the main adjustment frame 100, which saves time and effort. It is understandable that the structure and connection method of the secondary adjustment frame 200 can also be the same as those of the main adjustment frame 100, and will not be repeated here.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the first half frame 101 is provided with a first flange 103 at one end away from its hinge point, and the second half frame 102 is correspondingly provided with a second flange 104, and the first flange 103 and the second flange 104 are connected by bolts. Specifically, the first flange 103 and the second flange 104 are both provided with through-holes. When the main adjustment frame 100 needs to be installed on the outer wall of the steel pipe segment 600, the first flange 103 and the second flange 104 are fitted together, and the two mounting holes are coaxially aligned, and then the bolts are inserted and tightened. It should be noted that the end of the first half frame 101 away from its hinge point can also be connected with the corresponding end of the second half frame 102 by snapping. There are many ways of snapping connections, which will not be repeated here.

[0043] In some embodiments of the present invention, Figure 2As shown, an auxiliary installation mechanism 400 is detachably disposed between the first flange 103 and the second flange 104. The auxiliary installation mechanism 400 includes a first supporting portion 401 and a first hydraulic cylinder 402. The first supporting portion 401 is provided with a first groove 403. One sidewall of the first groove 403 abuts against the end face of the first flange 103 facing away from the second flange 104. One end of the first hydraulic cylinder 402 supports the other sidewall of the first groove 403, while the other end of the first hydraulic cylinder 402 supports the end face of the second flange 104 facing away from the first flange 103. Due to processing errors in the steel pipe segment 600 and collisions during transportation, the size and shape of the interface of the steel pipe segment 600 may deviate from the design standard, making it more difficult to install the main adjustment frame 100 outside the interface of the steel pipe segment 600. In this embodiment, the auxiliary installation mechanism 400 can be detachably arranged between the first flange 103 and the second flange 104. Under normal circumstances, the auxiliary installation mechanism 400 is not needed. When it is more difficult to install the main adjustment frame 100 at the interface of the steel pipe segment 600, one of the side walls of the first groove 403 on the first supporting portion 401 is fitted into the end face of the first flange 103 facing away from the second flange 104, one end of the first hydraulic cylinder 402 is fitted into the other side wall of the first groove 403, and the other end of the first hydraulic cylinder 402 is fitted into the end face of the second flange 104 facing away from the first flange 103, and then the first hydraulic cylinder 402 is started. The first hydraulic cylinder 402 is extended to support the first flange 103 and the second flange 104 to move towards each other. When the first flange 103 and the second flange 104 are fitted into each other, the bolts are inserted and tightened, and then the auxiliary installation mechanism 400 is removed. In this embodiment, the auxiliary installation mechanism 400 can assist in the fastening installation of the main adjustment frame 100, making the installation more convenient, saving time and effort, and can be removed when not needed, making it easy to use.

[0044] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, an annular mounting portion 105 protruding from the outer wall of the main adjustment frame 100 is provided at both ends of the main adjustment frame 100, and the end of the adjustment screw 301 away from the through hole is connected to the annular mounting portion 105. The annular mounting portion 105 is provided to facilitate the installation of the adjustment screw 301.

[0045] In some embodiments of the present invention, Figure 3As shown, a local adjustment mechanism 500 is detachably provided between the secondary adjustment frame 200 and the adjacent annular mounting portion 105. The local adjustment mechanism 500 includes a second supporting portion 501 and a second hydraulic cylinder 502. The second supporting portion 501 is provided with a second groove 503. One sidewall of the second groove 503 abuts against the end face of the secondary adjustment frame 200 facing away from the primary adjustment frame 100. One end of the second hydraulic cylinder 502 supports the other sidewall of the second groove 503, while the other end of the second hydraulic cylinder 502 supports the end face of the annular mounting portion 105 facing away from the corresponding secondary adjustment frame 200. Due to machining errors of the steel pipe segments 600 and construction errors during the docking process of the steel pipe segments 600, the gap size at a local location of the docking groove may still be larger than the designed size after the steel pipe segments 600 are docked. Due to the low structural strength of the adjusting screw 301, there is a safety risk when adjusting using the adjusting screw 301. In this embodiment, when the gap size at a local location of the butt joint bevel of the steel pipe segment 600 is larger than the designed size, the local adjustment mechanism 500 of this embodiment can be installed at the corresponding local location. Specifically, one side wall of the second groove 503 of the second supporting portion 501 is placed against the end face of the secondary adjustment frame 200 facing away from the main adjustment frame 100 and corresponding to the location where the groove gap needs to be adjusted. One end of the second hydraulic cylinder 502 is placed against the other side wall of the second groove 503, and the other end of the second hydraulic cylinder 502 is placed against the annular mounting portion 105 facing away from the end face of the corresponding secondary adjustment frame 200 and corresponding to the location where the groove gap needs to be adjusted. The second hydraulic cylinder 502 is then activated and extended, thereby reducing the distance between the local location of the main adjustment frame 100 and the corresponding secondary adjustment frame 200, thereby reducing the gap size at the local location of the butt joint bevel of the steel pipe segment 600, so that the gap size at the local location meets the designed requirements. Auxiliary adjustment is performed through the local adjustment mechanism 500, which is simple and convenient to operate and has higher safety. The local adjustment mechanism 500 can be removed when it is not needed, and is easy to use.
