Description

Technical Field

[0001] This utility model belongs to the field of welding equipment technology, and specifically relates to an ultrasonic welding quality monitoring device. Background Technology

[0002] On construction sites, steel pipes serve as critical load-bearing and conveying components, and their welding quality directly affects the safety and stability of the overall engineering structure. Therefore, comprehensive inspection of steel pipe welds is necessary through ultrasonic welding quality monitoring. Currently, ultrasonic monitoring of steel pipe welds often employs a circumferential inspection method. This involves placing the monitoring equipment around the steel pipe and using the monitoring probe on the equipment to move circumferentially around the pipe, achieving full circumferential coverage of the weld. This allows for accurate identification of potential hidden defects such as bubbles, cracks, and lack of fusion within the weld, providing data support for controlling the welding quality of steel pipes.

[0003] A search revealed a novel high-alloy steel pipe welding quality device (CN222774502U), comprising an installation cylinder with adjusting screws threaded around its circumference. An operating rod is welded to the outer end of each adjusting screw, and a tightening seat is threaded to the inner end of the adjusting screw. A protective cover is bolted to the left end of the installation cylinder. A movable detection support structure is movably supported on the left side inside the installation cylinder. This movable detection support structure includes an installation ring, with a worm gear embedded in the left side of the outer wall of the installation ring. A worm is engaged at the upper end of the worm gear, and a stepper motor is embedded at the right end of the worm. A transverse support frame structure is also included.

[0004] Existing ultrasonic welding quality monitoring equipment, when mounted on steel pipes, cannot guarantee concentricity with the pipes. Insufficient concentricity causes the distance between the monitoring probe and the weld joint to fluctuate as the probe moves around the weld joint, making it impossible to accurately assess the welding quality of the steel pipe. Utility Model Content

[0005] The purpose of this utility model is to provide an ultrasonic welding quality monitoring device to solve the problem mentioned in the background art that after the ultrasonic welding quality monitoring device is mounted on the steel pipe, it cannot be guaranteed to be concentric with the steel pipe. Insufficient concentricity causes the distance between the monitoring probe and the weld to fluctuate when the probe moves around the weld of the steel pipe, making it impossible to accurately assess the welding quality of the steel pipe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An ultrasonic welding quality monitoring device, comprising: Mobile rack; Adaptive components are mounted on the mobile frame; The mounting bracket connects to the adaptive component and moves adaptively relative to the moving frame via the adaptive component. A rotating frame, rotatably mounted on a mounting frame, is used to surround and sleeve the steel pipe being monitored; Several guide rods are arranged in a circular array and installed on the rotating frame. The guide rods are used to contact the outer surface of the steel pipe being monitored. Through the contact and cooperation between the guide rods and the outer surface of the steel pipe, the rotating frame and the mounting frame can be driven to adjust their positions relative to the moving frame through the adaptive component. An ultrasonic flaw detector head, mounted on a rotating frame, is used to inspect the weld seams of steel pipes.

[0007] In one embodiment, the adaptive component includes a first buffer ring and a second buffer ring, the mounting bracket is disposed within the second buffer ring, the second buffer ring is mounted within the first buffer ring, the mounting bracket is configured to move vertically within the second buffer ring, and the second buffer ring is configured to move horizontally within the first buffer ring.

[0008] In one embodiment, the second buffer ring includes: Two second connecting rods are installed at the top and bottom of the mounting bracket, respectively. Two second through holes are opened on the second buffer ring, and the two second connecting rods pass through the two second through holes respectively.

[0009] In one embodiment, the second buffer ring further includes: The second elastic element is installed between the mounting bracket and the second buffer ring.

[0010] In one embodiment, the first buffer ring includes: Two first connecting rods are installed on the second buffer ring. The first buffer ring has two first through holes, and the two first connecting rods pass through the two second through holes respectively.

[0011] In one embodiment, the first buffer ring further includes: The first elastic element is installed between the first buffer ring and the second buffer ring.

[0012] In one embodiment, one end of the guide rod is rotatably connected to a contact wheel.

[0013] In one embodiment, it also includes: The mounting base is mounted on the rotating frame, and the ultrasonic flaw detector head is mounted on the mounting base.

[0014] In a preferred embodiment, the mounting base includes: An adjustment groove is provided on the mounting base; An adjustment seat is installed in the adjustment groove, and the ultrasonic flaw detector head is installed on the adjustment seat; The lead screw is installed in the adjustment groove. One end of the lead screw is threaded to the adjustment seat, and the other end is equipped with an adjustment knob, which is set on the mounting seat.

[0015] In a preferred embodiment, the mounting bracket includes: The first gear is mounted on the rotating frame; A power source is mounted on the mounting bracket, and a second gear is connected to the power shaft of the power source, which meshes with the first gear.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a circular array of guide rods and nested first and second buffer rings to form a multi-directional adaptive adjustment mechanism. After the guide rods are attached to the outer surface of the steel pipe, if there is a horizontal deviation in the steel pipe, the second buffer ring can drive the rotating frame to move horizontally within the first buffer ring, with the first elastic element providing elastic support and stability. If there is a vertical deviation, the mounting frame can drive the rotating frame to adjust vertically within the second buffer ring. This bidirectional, independent, and coordinated adjustment action can actively compensate for positional deviations during steel pipe installation, ensuring that the rotating frame remains concentric with the steel pipe and stabilizing the detection distance between the ultrasonic flaw detector head and the weld.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1-5 An ultrasonic welding quality monitoring device, comprising: Mobile rack 100; Adaptive component 200 is mounted on the movable frame 100; Mounting frame 300 is connected to adaptive component 200 and adaptively moves relative to moving frame 100 via adaptive component 200; The rotating frame 301 is rotatably mounted on the mounting frame 300 and is used to surround and sleeve the steel pipe being monitored. Several guide rods 302 are arranged in a circular array and installed on the rotating frame 301. The guide rods 302 are used to contact the outer surface of the steel pipe being monitored. Through the contact and cooperation between the several guide rods 302 and the outer surface of the steel pipe, the rotating frame 301 and the mounting frame 300 can be driven to adjust their positions relative to the moving frame 100 through the adaptive component 200. The ultrasonic flaw detector head 401 is mounted on the rotating frame 301 and is used to inspect the weld seams of steel pipes.

[0025] Specifically, the movable frame 100 serves as the load-bearing and moving foundation of the entire device, and its design allowing movement along the axial direction of the steel pipe provides motion support for full-length weld monitoring. The mounting frame 300 connects the adaptive component 200 and the rotating frame 301, acting as a force and motion transmission mechanism, allowing the position adjustment of the rotating frame 301 to be transmitted to the adaptive component 200 via the mounting frame 300. The rotating frame 301 is rotatably mounted on the mounting frame 300, and its structure surrounding the steel pipe provides a motion carrier for the circumferential flaw detection of the ultrasonic flaw detector head 401. Several guide rods 302 arranged in a circular array are installed inside the rotating frame 301. When the rotating frame 301 is fitted with the steel pipe, the guide rods 302 and the outer surface of the steel pipe... By utilizing the force-balanced characteristics brought about by the circumferential array distribution, when there is a slight outer diameter deviation, the guide rod 302 can drive the rotating frame 301 to shift position through the contact force with the steel pipe surface. This shifting force is transmitted to the adaptive component 200 through the mounting frame 300, so that the mounting frame 300 adjusts its position relative to the moving frame 100 under the action of the adaptive component 200, thereby achieving concentric calibration between the rotating frame 301 and the steel pipe. The ultrasonic flaw detector head 401 rotates circumferentially with the rotating frame 301 to perform circumferential flaw detection on the weld. Combined with the axial movement of the moving frame 100, a comprehensive inspection of the weld is completed, ensuring that the distance between the probe and the weld is stable during the flaw detection process, and guaranteeing the technical accuracy of ultrasonic flaw detection.

[0026] In the above technical solution, a number of guide rods 302 arranged in a circular array contact and cooperate with the outer surface of the steel pipe. Combined with the adaptive component 200, which allows the mounting frame 300 to adaptively adjust its position relative to the moving frame 100, the rotating frame 301 can be driven to adjust synchronously and always remain concentric with the steel pipe being monitored. This avoids the ultrasonic flaw detector head 401 from moving closer and farther from the weld when it rotates with the rotating frame 301, ensuring a stable ultrasonic wave propagation path and improving the accuracy and reliability of the flaw detection data.

[0027] In one embodiment, the adaptive component 200 includes a first buffer ring 201 and a second buffer ring 202, the mounting bracket 300 is disposed within the second buffer ring 202, the second buffer ring 202 is mounted within the first buffer ring 201, the mounting bracket 300 is configured to move vertically within the second buffer ring 202, and the second buffer ring 202 is configured to move horizontally within the first buffer ring 201.

[0028] In the above technical solution, the first buffer ring 201 is fixedly installed on the movable frame 100 as the basic carrier for horizontal adjustment, providing installation space and guiding support for the horizontal movement of the second buffer ring 202; the second buffer ring 202 is nested inside the first buffer ring 201, and its cooperation structure with the first buffer ring 201 allows it to move freely in the horizontal direction, while providing a vertical movement reference for the mounting frame 300; the mounting frame 300 is nested inside the second buffer ring 202, and the connection structure between the two limits the mounting frame 300 to move only in the vertical direction, and the mounting frame 300 is directly connected to the rotating frame 301, so that its own vertical movement and the horizontal movement of the second buffer ring 202 can be synchronously transmitted to the rotating frame 301.

[0029] Specifically, when the rotating frame 301 is fitted onto the outer circumference of the steel pipe, several guide rods 302 arranged in a circular array contact the surface of the steel pipe and form a uniform contact force. If the steel pipe has a horizontal positional deviation, the guide rods 302 will be subjected to a horizontal reaction force from the surface of the steel pipe. This force is transmitted to the mounting frame 300 through the rotating frame 301, and then the mounting frame 300 drives the second buffer ring 202 to move horizontally within the first buffer ring 201 until the rotating frame 301 is aligned with the steel pipe in the horizontal direction. If the steel pipe has a vertical positional deviation, the vertical reaction force on the guide rods 302 will directly push the rotating frame 301 to drive the mounting frame 300 to move vertically within the second buffer ring 202, completing the vertical positional calibration. Through independent and coordinated buffering adjustments in the horizontal and vertical directions, it is ensured that the rotating frame 301 always remains concentric with the steel pipe, and the distance between the ultrasonic flaw detector head 401 and the weld seam remains stable when the rotating frame 301 rotates.

[0030] In one embodiment, the second buffer ring 202 includes: two second connecting rods 206, which are respectively installed on the top and bottom of the mounting bracket 300, and two second through holes are opened on the second buffer ring 202, through which the two second connecting rods 206 pass respectively; and a second elastic member 205, which is installed between the mounting bracket 300 and the second buffer ring 202.

[0031] In one embodiment, the first buffer ring 201 includes: two first connecting rods 204 mounted on the second buffer ring 202, the first buffer ring 201 having two first through holes, the two first connecting rods 204 respectively passing through the two second through holes; and a first elastic member 203 mounted between the first buffer ring 201 and the second buffer ring 202.

[0032] Specifically, the first elastic element 203 and the second elastic element 205 are both elastic sheets, and can also be compression springs. The first buffer ring 201 is fixed to the movable frame 100 as the basic structure for horizontal adjustment. The two first through holes provided by the first ring 201 provide directional guide channels for the first connecting rod 204. The two first connecting rods 204 are installed on the second buffer ring 202 and pass through the first through holes, limiting the second buffer ring 202 to move only in the horizontal direction along the first through holes. The first elastic element 203 connects the first buffer ring 201 and the second buffer ring 202. When the second buffer ring 202 is subjected to force, the first elastic element 203 can undergo tensile or compressive deformation as the second buffer ring 202 moves horizontally, providing elastic support for movement and also driving the second buffer ring 202 back to its initial position through elastic restoring force after the force disappears.

[0033] The second buffer ring 202 serves as a carrier for vertical adjustment. Its two second through holes provide a vertical guide path for the second connecting rod 206. The two second connecting rods 206 are installed at the top and bottom of the mounting frame 300 and pass through the second through holes, so that the mounting frame 300 can only move in the vertical direction of the second through holes. The second elastic element 205 connects the mounting frame 300 and the second buffer ring 202. When the mounting frame 300 moves vertically, the second elastic element 205 deforms accordingly, providing the mounting frame 300 with a vertical buffer force and a restoring force.

[0034] After the rotating frame 301 is fitted with the steel pipe, the guide rods 302 distributed in a circular array come into contact with the surface of the steel pipe. If the steel pipe is horizontally offset, the guide rods 302 are subjected to a horizontal reaction force from the surface of the steel pipe. This force is transmitted to the rotating frame 301, and then to the mounting frame 300. The mounting frame 300 drives the second buffer ring 202, causing the second buffer ring 202 to move horizontally in the first through hole of the first buffer ring 201 through the first connecting rod 204. The first elastic element 203 deforms to adapt to the movement and provides stable support until the horizontal position of the rotating frame 301 is aligned with the steel pipe. If the steel pipe is vertically offset, the vertical reaction force on the guide rods 302 is transmitted to the mounting frame 300 through the rotating frame 301. The mounting frame 300 moves vertically in the second through hole of the second buffer ring 202 through the second connecting rod 206. The second elastic element 205 deforms to buffer and assist in position calibration, ultimately achieving concentric adjustment between the rotating frame 301 and the steel pipe.

[0035] In one embodiment, a contact wheel is rotatably connected to one end of the guide rod 302. One end of the guide rod 302 is connected to the contact wheel via a rotating joint, allowing the contact wheel to rotate freely around its own axis. When the rotating frame 301 is fitted onto the outer circumference of the steel pipe being monitored, the circumferentially arrayed guide rods 302 drive the contact wheel to form a uniformly fitted contact with the outer surface of the steel pipe. The wheel surface of the contact wheel makes line contact with the outer surface of the steel pipe, providing initial positioning support for the rotating frame 301. When there is a horizontal positional deviation in the steel pipe, the contact wheel experiences a horizontal reaction force from the surface of the steel pipe. This force is transmitted through the guide rod 302 to the rotating frame 301, and then from the rotating frame 301 to the mounting frame 300. This causes the mounting frame 300 to move the second buffer ring 202 horizontally within the first buffer ring 201. During this process, the contact wheel rolls on the surface of the steel pipe as the second buffer ring 202 moves horizontally, converting sliding friction into rolling friction and reducing resistance during horizontal adjustment.

[0036] In one embodiment, the device further includes: a mounting base 400 mounted on a rotating frame 301, with the ultrasonic flaw detector head 401 mounted on the mounting base 400. The mounting base 400 includes: an adjustment groove formed in the mounting base 400; an adjustment seat 402 mounted within the adjustment groove, with the ultrasonic flaw detector head 401 mounted on the adjustment seat 402; and a lead screw 403 mounted within the adjustment groove, one end of which is threadedly connected to the adjustment seat 402, and the other end of which is fitted with an adjustment knob 404, which is located on the mounting base 400.

[0037] In the above technical solution, the mounting base 400 serves as the support and adjustment foundation for the ultrasonic flaw detector head 401, and is fixedly mounted on the rotating frame 301, providing a stable installation reference for the subsequent adjustment structure. An adjustment groove is formed on the mounting base 400, and its groove structure is adapted to the shape of the adjustment seat 402, thus limiting the movement direction of the adjustment seat 402 and ensuring that the adjustment seat 402 can only move along the extension direction of the adjustment groove, avoiding lateral displacement during adjustment. The adjustment seat 402 is installed in the adjustment groove and is directly connected to the ultrasonic flaw detector head 401; its movement can directly drive... The position of the ultrasonic flaw detector head is adjusted synchronously. The lead screw 403 is installed in the adjustment groove, with one end connected to the adjustment seat 402 by a thread, and the other end extending out of the mounting seat 400 and fixed to the adjustment knob 404. Utilizing the characteristics of threaded transmission, when the operator rotates the adjustment knob 404, the knob drives the lead screw 403 to rotate around its own axis. The rotational motion of the lead screw 403 is converted into linear motion of the adjustment seat 402 along the extension direction of the adjustment groove through the threaded pair, thereby achieving precise fine-tuning of the position of the ultrasonic flaw detector head 401 and ensuring that the flaw detector head can be adjusted to the optimal detection position according to the actual detection requirements.

[0038] In a preferred embodiment, the mounting frame 300 includes: a first gear 303 mounted on a rotating frame 301; a power source 304 mounted on the mounting frame 300, wherein a second gear 305 is connected to the power shaft of the power source 304, and the second gear 305 meshes with the first gear 303.

[0039] Specifically, the power source 304 is a servo motor, or it can be a stepper motor. When the device starts the flaw detection operation, the power source 304 is powered on and drives the power shaft to rotate around its own axis. The second gear 305 connected to the power shaft rotates synchronously. Since the second gear 305 and the first gear 303 are in a meshing state, the rotation of the second gear 305 will drive the first gear 303 to rotate through the interaction force between the tooth surfaces. The first gear 303 is fixed to the rotating frame 301. Therefore, the rotation of the first gear 303 will directly drive the rotating frame 301 to rotate around the axis of the steel pipe being monitored. The mounting frame 300 provides fixed support for the power source 304 and the second gear 305, ensuring that the second gear 305 and the first gear 303 always maintain a stable meshing state and avoid changes in the gear meshing clearance due to loose parts. When the rotating frame 301 rotates, the ultrasonic flaw detection head 401 mounted on it moves synchronously circumferentially with the rotating frame 301, and completes the weld inspection in conjunction with the axial movement of the moving frame 100.

[0040] The working principle and usage process of this utility model are as follows: When monitoring the ultrasonic welding quality of steel pipes, the device is first moved to the vicinity of the weld to be inspected on the steel pipe. The moving frame 100 is pushed so that the rotating frame 301 surrounds the outer circumference of the steel pipe being monitored. At this time, the contact wheel at one end of the guide rod 302, which is distributed in a circular array on the inner side of the rotating frame 301, is in contact with the outer surface of the steel pipe. If there is a horizontal positional deviation in the steel pipe, the contact wheel is subjected to a horizontal reaction force from the surface of the steel pipe. This force is transmitted sequentially through the guide rod 302 and the rotating frame 301 to the mounting frame 300. The mounting frame 300 drives the second buffer ring 202, so that the second buffer ring 202 passes through the first connecting rod 204 installed on it in the first buffer... The first elastic element 203 between the first buffer ring 201 and the second buffer ring 202 moves horizontally within the first through hole of the ring 201. This elastic element 203 deforms as the second buffer ring 202 moves, providing elastic support until the rotating frame 301 is horizontally aligned with the steel pipe. If the steel pipe has a vertical positional deviation, the vertical reaction force on the contact wheel is transmitted sequentially through the guide rod 302 and the rotating frame 301 to the mounting frame 300. The mounting frame 300 moves vertically within the second through hole of the second buffer ring 202 via the second connecting rod 206 mounted on it. This elastic element 205 between the second buffer ring 202 and the mounting frame 300 deforms as the mounting frame 300 moves, providing elastic support. The system uses a buffer force to complete vertical position calibration, ultimately achieving concentric adjustment between the rotating frame 301 and the steel pipe. After concentric calibration, the power source 304 on the mounting frame 300 is activated. The power shaft of the power source 304 drives the second gear 305 connected to it to rotate. Because the second gear 305 meshes with the first gear 303 mounted on the rotating frame 301, the second gear 305 drives the first gear 303 to rotate through the tooth surface force, causing the rotating frame 301 to rotate around the axis of the steel pipe. The ultrasonic flaw detector head 401, installed in the mounting base 400 on the rotating frame 301, moves synchronously circumferentially with the rotating frame 301 to perform circumferential flaw detection on the weld seam of the steel pipe. At the same time, the moving frame 100 is pushed, causing the moving frame... The device moves along the axial direction of the steel pipe, and the ultrasonic flaw detector head 401 moves axially with the device while rotating circumferentially to detect flaws, thus achieving full-length coverage inspection of the steel pipe weld. If the position of the ultrasonic flaw detector head 401 needs to be adjusted during the inspection, the operator rotates the adjustment knob 404 on the mounting base 400. The adjustment knob 404 drives the lead screw 403 installed in the adjustment groove to rotate around its own axis. The lead screw 403 converts the rotational motion into linear motion of the adjustment seat 402 along the extension direction of the adjustment groove through the threaded pair. The adjustment seat 402 drives the ultrasonic flaw detector head 401 installed on it to move synchronously until the ultrasonic flaw detector head 401 is adjusted to the optimal inspection position, and the weld inspection operation is continuously completed. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
