Description

Technical Field

[0001] The utility model belongs to the technical field of welded pipe production, and more specifically relates to a layout structure of a welded pipe UT automatic flaw detection operation line. Background Art

[0002] At present, the layout structure of the domestic ultrasonic (UT) automatic flaw detection line for welded pipes is as follows: Figure 1 As shown, it includes an inspection room 100, in which an ultrasonic flaw detection frame and a flaw detection vehicle 400 are provided. A pre-inspection station 200 and a post-inspection station 300 are respectively provided on the left and right sides of the inspection room 100. A transfer vehicle 500 is provided on the same side of the pre-inspection station 200 and the post-inspection station 300. When the flaw detection starts, the flaw detection vehicle 400 is parked on the pre-inspection station 200, and the welded pipe to be inspected is transferred to the flaw detection vehicle 400 by the transfer vehicle 500. When the flaw detection vehicle 400 is started, the welded pipe to be inspected is transported into the inspection room 100, and the welded pipe is ultrasonically inspected. After the inspection is completed, the flaw detection vehicle 400 transports the welded pipe to the post-inspection station 300, and the transfer vehicle 500 transports the inspected welded pipe to the next process. In actual production, taking a welded pipe with a length of 13.5m as an example, the design length of the above-mentioned flaw detection vehicle 400 is 14m. In order to avoid interference between the welded pipe and the inspection chamber 100, the distance between the pre-inspection station 200 and the post-inspection station 300 and the inspection chamber 100 is required to be at least 2m. The length of the ultrasonic flaw detection frame in the inspection chamber 100 is 2.5m, and the welded pipe is required to pass under the ultrasonic flaw detection frame. Therefore, the minimum design length of the inspection chamber 100 is the sum of the length of the welded pipe and the length of the ultrasonic flaw detection frame, which is 16m. In this way, the total design length of the above-mentioned existing ultrasonic automatic flaw detection and inspection operation line is more than 48m. Due to the long design length of the ultrasonic automatic flaw detection and inspection operation line, a larger factory building is required, which increases the construction cost in disguise. On the other hand, during the welded pipe inspection process, the flaw detection vehicle 400 needs to move back and forth between the pre-inspection station 200 and the post-inspection station 300 to transport the welded pipe. The flaw detection vehicle 400 has a long travel route, takes a lot of time, and results in low operating efficiency. Utility Model Content

[0003] The utility model aims to provide a layout structure of a welded pipe UT automatic flaw detection operation line, aiming to solve the problem of low efficiency of ultrasonic automatic flaw detection of welded pipes in the background technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a layout structure of a welded pipe UT automatic flaw detection operation line, comprising:

[0005] A long beam, wherein the long beam is provided with a traveling mechanism that moves along its length direction;

[0006] A support assembly is provided below the long beam. There are two support assemblies, which are spaced apart along the length direction of the long beam and are used to support the two ends of the axial side of the welded pipe respectively.

[0007] An ultrasonic detection frame, the ultrasonic detection frame is connected to the traveling mechanism and is located between the long beam and the support assembly. The ultrasonic detection frame is provided with an ultrasonic probe. The traveling mechanism moves to drive the ultrasonic probe to detect the welded pipe;

[0008] A transverse transfer vehicle is provided on one side of the long beam in the width direction, and is used to transfer the welded pipe to the support assembly or to transfer the welded pipe out of the support assembly.

[0009] In a possible implementation, longitudinal supports are provided at both ends of the long beam, the lower ends of the longitudinal supports are fixed to the ground, and the long beam is connected between the tops of the two longitudinal supports so that the long beam is suspended above the ground.

[0010] In a possible implementation, a first lifting mechanism is provided on the walking mechanism, and an action end of the first lifting mechanism is connected to the ultrasonic detection frame for driving the ultrasonic detection frame to move up and down.

[0011] In a possible implementation, the support assembly includes two support parts symmetrically arranged along the width direction of the long beam, and the distance between the two support parts is smaller than the diameter of the welded pipe, so that there is a support gap between the two support parts for clamping the welded pipe end.

[0012] In a possible implementation, the support portion includes two columns spaced apart along the length direction of the long beam, and a support roller is rotatably connected between the tops of the two columns, and the support roller is used to support the welded pipe.

[0013] In a possible implementation, at least one of the support rollers is a driving roller, and the driving roller is driven by a motor to drive the welded pipe to rotate.

[0014] In a possible implementation, a guide rail is provided between the two support assemblies along the width direction of the long beam, the guide rail is fixed on the ground, and the transverse vehicle is slidably disposed on the guide rail.

[0015] In a possible implementation, a transfer platform for loading welded pipes is provided on the transverse vehicle, and a second lifting mechanism is provided between the transfer platform and the transverse vehicle, and the second lifting mechanism is used to drive the transfer platform to move up and down.

[0016] In a possible implementation, a slot is provided in the middle of the transfer platform along the length direction of the long beam, and the welding pipe is inserted into the slot, and the slot is used to limit the lateral movement of the welding pipe.

[0017] In a possible implementation, the side walls of the slot are tilted inward from top to bottom.

[0018] The beneficial effect of the arrangement structure of the UT automatic flaw detection operation line for welded pipes provided by the present invention is that, compared with the prior art, when ultrasonic testing is performed on welded pipes, the welded pipes are first transferred to the support assembly by a transverse vehicle, and then the traveling mechanism provided on the crossbeam is activated to drive the ultrasonic probe on the ultrasonic testing frame to move from one end of the welded pipe to the other end to perform testing on the welded pipe. After the testing is completed, the transverse vehicle transfers the welded pipe from the support assembly to the next process. The arrangement structure of the UT automatic flaw detection operation line for welded pipes provided by the present invention eliminates the provision of the flaw detection vehicle in the prior art, which, on the one hand, reduces the space occupied by the UT automatic flaw detection operation line for welded pipes, and on the other hand, eliminates the operation step of the flaw detection vehicle transferring the welded pipes, thereby reducing the transfer time of the welded pipes and improving the operating efficiency.

[0030] See also Figures 2 to 4The present invention provides a layout structure for an automatic flaw detection line for welded pipes using UT technology. The layout structure comprises a long beam 1, a support assembly 2, an ultrasonic detection frame 3, and a transverse vehicle 4. The long beam 1 is provided with a traveling mechanism 5 that moves along its length. The support assembly 2 is provided below the long beam 1. There are two support assemblies 2, which are spaced apart along the length of the long beam 1. The two support assemblies 2 are used to support both ends of the axial side of the welded pipe 8. The ultrasonic detection frame 3 is connected to the traveling mechanism 5 and is located between the long beam 1 and the support assembly 2. The ultrasonic detection frame 3 is provided with an ultrasonic probe. The traveling mechanism 5 moves to drive the ultrasonic probe to detect the welded pipe 8. The transverse vehicle 4 is provided on one side of the long beam 1 in the width direction. The transverse vehicle 4 is used to transfer the welded pipe 8 to or from the support assembly 2.

[0031] The present invention provides a layout structure for an automatic flaw detection line for welded pipes (UT). Compared with the prior art, when ultrasonic testing is performed on a welded pipe 8, the welded pipe 8 is first transferred to the support assembly 2 by a transverse vehicle 4. Then, the traveling mechanism 5 provided on the crossbeam is activated to drive the ultrasonic probe on the ultrasonic testing frame 3 to move from one end of the welded pipe 8 to the other end to perform testing on the welded pipe 8. After the testing is completed, the transverse vehicle 4 transfers the welded pipe 8 from the support assembly 2 to the next process. The present invention provides a layout structure for an automatic flaw detection line for welded pipes (UT), which eliminates the need for a flaw detection vehicle in the prior art. This reduces the space occupied by the automatic flaw detection line for welded pipes (UT), and eliminates the need for the flaw detection vehicle to transfer the welded pipe 8, thereby reducing the transfer time of the welded pipe 8 and improving operational efficiency.

[0032] In this example, see Figures 2 to 4 Longitudinal supports 11 are provided at both ends of the long beam 1. The lower ends of the longitudinal supports 11 are fixed to the ground. The long beam 1 is connected between the tops of the two longitudinal supports 11 so that the long beam 1 is suspended above the ground. In this embodiment, the walking mechanism 5 is an electric trolley mounted on the upper end surface of the long beam 1. A long avoidance hole 101 is provided in the middle portion of the long beam 1 along its length, extending vertically through the long beam 1. A first elevator is connected to the electric trolley. The lifting end of the first lifting mechanism 6 extends through the long avoidance hole 101 to the lower end of the long beam 1. The ultrasonic detection frame 3 is mounted on the lifting end of the first lifting mechanism 6. In actual applications, the first lifting mechanism 6 can be a screw linear module or a winch, or other commonly used drive mechanism. In this embodiment, the first lifting mechanism 6 can drive the ultrasonic detection frame 3 up and down, thereby adjusting the height of the ultrasonic detection frame 3 so that the ultrasonic probe on the ultrasonic detection frame 3 can contact the welded pipe 8.

[0033] In some embodiments, see Figure 2 and Figure 4The above-mentioned support assembly 2 includes two support parts symmetrically arranged along the width direction of the long beam 1. The distance between the two support parts is smaller than the diameter of the welded pipe 8, so that there is a support gap 211 between the two support parts for clamping the end of the welded pipe 8. Specifically, the support part includes two columns 21 spaced apart along the length direction of the long beam 1. A support roller 22 is rotatably connected between the tops of the two columns 21. In use, the welded pipe 8 is pressed against the support roller 22, and the support roller 22 is used to support the welded pipe 8.

[0034] In actual operation, the welds on some welded pipes 8 are spiral, and the welded pipes 8 need to be rotated during inspection. In this embodiment, at least one of the above-mentioned multiple support rollers 22 is a driving roller, and the driving roller is driven by an external motor. During operation, the motor drives the driving roller to rotate, and the friction between the welded pipe 8 and the driving roller can be used to drive the welded pipe 8 to rotate to complete the inspection.

[0035] In some embodiments, see Figures 2 to 4 A guide rail 7 is provided between the two support assemblies 2 along the width direction of the long beam 1. The guide rail 7 is fixed on the ground, and the transverse vehicle 4 is slidably set on the guide rail 7. By setting the guide rail 7 to guide the transverse vehicle 4 to move, it can be avoided that the transverse vehicle 4 is skewed during movement, causing the welded pipe 8 to be skewed and difficult to move to the support assembly 2.

[0036] In some embodiments, there are two transverse vehicles 4, which are respectively arranged on both sides of the width direction of the long beam 1. One transverse vehicle 4 is responsible for transferring the welded pipe 8 to be inspected to the support assembly 2 for inspection, and the other transverse vehicle 4 is responsible for transferring the welded pipe 8 that has completed inspection from the support assembly 2 to the next process position. This arrangement improves the transportation efficiency of the welded pipe 8.

[0037] In this example, see Figures 2 to 4 A transfer platform 41 for loading the welded pipe 8 is provided on the transverse vehicle 4. A second lifting mechanism is provided between the transfer platform 41 and the transverse vehicle 4. The second lifting mechanism is used to drive the transfer platform 41 to move up and down. In this embodiment, the second lifting mechanism can be a scissor-type lift or a telescopic rod group composed of multiple telescopic tubes. A slot 42 is provided in the middle of the transfer platform 41 along the length direction of the long beam 1. The welded pipe 8 is inserted into the slot 42. The slot 42 is used to limit the lateral movement of the welded pipe 8. In use, when the welded pipe 8 to be tested is placed in the slot 42 on the transfer platform 41, the transfer platform 41 is raised by the second lifting mechanism so that the height of the welded pipe 8 is higher than the support mechanism. When the transverse vehicle 4 moves between the two support assemblies 2, the transfer platform 41 is moved downward by the second lifting mechanism so that the welded pipe 8 is clamped between the two support assemblies 2. After the transfer platform 41 and the welded pipe 8 are separated, the transverse vehicle 4 can be driven to withdraw from between the two support assemblies 2.

[0038] In this embodiment, the side walls of the slot 42 are tilted inward from top to bottom. This configuration allows the side walls of the slot 42 to guide the welding pipe 8 when supporting it, making it easier for the welding pipe 8 to be stuck in the slot 42.

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