Description

Technical Field

[0001] This utility model relates to PVC pipe production technology, and in particular to a PVC pipe testing drive device. Background Technology

[0002] In the PVC pipe manufacturing process, in order to ensure that the product quality meets the standards and to prevent pipes with structural defects (such as uneven wall thickness, internal cracks, and joint defects) from entering the market, it is necessary to conduct comprehensive testing on the pipes. As the core equipment in the pipe testing process, the performance of the testing drive device directly determines the testing efficiency and accuracy.

[0003] First, the probe transfer mechanism has poor flexibility, mostly consisting of fixed tracks or a single drive component. It is difficult to adjust the probe position and spacing according to the pipe diameter and length, resulting in insufficient displacement accuracy. When switching to test different specifications of pipes, the component needs to be disassembled and reassembled, making the operation complex and inefficient.

[0004] Secondly, the pipe support and rotation mechanism is inadequate. Single-set roller support can easily cause long / heavy pipes to shift and sway, while multiple sets of support lack synchronous control. The axes of the support roller and the driven roller are difficult to align, resulting in unstable pipe rotation, surface wear, and affecting the accuracy of defect identification.

[0005] In addition, the device has poor compatibility, mostly adapting to a single or small range of pipe specifications. Changing the model requires replacing a large number of parts, resulting in high equipment costs. Furthermore, some parts are fixed connections, making maintenance and replacement difficult, which makes it hard to meet the testing requirements of high efficiency, accuracy, and multi-specification compatibility.

[0006] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a PVC pipe testing drive device that has greater industrial application value. Utility Model Content

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a PVC pipe detection drive device.

[0008] This utility model discloses a PVC pipe inspection driving device, including a conveying device for moving the inspection head, and a rotating seat on one side of the conveying device for supporting and driving the pipe to rotate.

[0009] The conveying device includes a support frame fixed to the foundation. The surface of the support frame has a working platform. The surface of the working platform has multiple sets of parallel electric lead screws. The moving block of the electric lead screw is equipped with two parallel extension rods, one above the other. The ends of the extension rods are used to install detection probes.

[0010] This PVC pipe inspection drive device includes a conveying device for transferring the inspection head. A rotating seat is provided on one side of the conveying device to support and drive the pipe to rotate. The conveying device is equipped with a bracket fixed to the foundation. A working platform is mounted on the surface of the bracket. Multiple sets of parallel electric screws are arranged on the surface of the working platform. Two parallel extension rods are mounted on the moving blocks of the electric screws. The ends of the extension rods are used to install the inspection probe. Through the cooperation of various components, the transfer of the inspection head and the support and rotation of the pipe can be realized during the inspection of PVC pipes.

[0011] Furthermore, a vertically extending plate is fixed on the movable block. Two sets of parallel waist-shaped holes are opened on the upper and lower sides of the surface of the plate. The tail end of the extension rod is fixed in the waist-shaped hole by an arc-shaped locking block and bolts and nuts, so that the distance between the two extension rods is adjustable.

[0012] The movable block is fixed with a vertically extending plate. Two sets of parallel waist-shaped holes are opened on the upper and lower sides of the plate surface. The tail end of the extension rod is fixed inside the waist-shaped hole by an arc-shaped locking block and bolts and nuts. With this connection method, the distance between the two extension rods can be adjusted to adapt to different usage needs.

[0013] Furthermore, there are two sets of conveying devices, which are arranged mirror images of the center line of the rotating seat.

[0014] The conveying device is set in two sets, which are distributed in a mirror image with the center line of the rotating seat as the reference. This layout allows the two sets of conveying devices to maintain symmetry and coordination when working with the rotating seat, providing a stable structural foundation for the subsequent movement of the inspection head and the rotation of the pipe support.

[0015] Furthermore, the rotating base includes a second bracket fixedly installed on the foundation. Above the second bracket are drive groups with the same number as the electric lead screw. Each drive group includes two sets of parallel support rollers. The midpoint of the line connecting the support rollers is on the same straight line as the axis of the electric lead screw. Each support roller is fixedly connected to a drive motor installed on the second bracket via a shaft.

[0016] The rotating base includes a second bracket fixedly installed on the foundation. A drive group is installed on the top of the second bracket, and the number of drive groups is consistent with the number of electric lead screws. Each drive group is equipped with two sets of parallel support rollers. The midpoint of the line connecting the support rollers is on the same straight line as the axis of the electric lead screw. At the same time, each support roller is fixedly connected to the drive motor installed on the second bracket through a shaft. This constitutes the core structure of the rotating base, providing a guarantee for the support and rotation of the pipe.

[0017] Furthermore, the rotating seat also includes a support three arranged parallel to the support two, on which driven rollers, the same number as the support rollers and located on the same axis, are installed.

[0018] The rotating seat also includes a third bracket, which is set in parallel with the second bracket. A driven roller is installed on the third bracket, and the number of driven rollers is the same as the number of support rollers. The driven rollers and support rollers are located on the same axis. By adding the third bracket and the driven rollers, the structure of the rotating seat is further improved, providing more stable support for the pipe.

[0019] Furthermore, a connecting rod is installed between the coaxial support roller and the driven roller.

[0020] A connecting rod is installed between the support roller and the driven roller located on the same axis. The connecting rod connects the coaxial support roller and the driven roller, making them form an integral structure, so as to enhance the synchronization and stability of the support roller and the driven roller during operation.

[0021] By means of the above-described solution, the present invention has at least the following advantages:

[0022] 1. Improved flexibility and efficiency of probe adjustment: The conveying device uses multiple sets of parallel electric screws to drive the moving block, which can accurately move the probe installed at the end of the extension rod. With the waist-shaped hole and arc-shaped locking block structure in the vertical plate of the moving block, the distance between the two extension rods can be flexibly adjusted. It can adapt to the testing needs of pipes of different diameters without disassembling and reassembling the components, greatly simplifying the operation process and solving the problems of poor flexibility and insufficient displacement accuracy of traditional probe conveying mechanisms, thus significantly improving testing efficiency.

[0023] 2. Ensuring pipe support stability and inspection accuracy: The two sets of conveying devices are set in mirror image of the center line of the rotating seat, and are matched with the number of drive groups on the rotating seat that are the same as the number of electric screws, so that the midpoint of the line connecting the support rollers is aligned with the axis of the electric screw, ensuring that the pipe is subjected to uniform force; the addition of the bracket three and the driven roller, as well as the connection between the coaxial support roller and the driven roller, further enhance the synchronization and stability of the pipe rotation, avoid pipe deviation and shaking, surface wear, effectively improve the accuracy of defect identification, and solve the problems of the traditional pipe support and rotation mechanism.

[0024] 3. Enhanced device compatibility and ease of maintenance: The device, with its adjustable extension rod spacing, multiple sets of adaptable drive components, and symmetrically arranged conveying devices, can be adapted to the testing of various specifications of PVC pipes without the need for extensive replacement of core components, thus reducing equipment investment costs. Each component adopts detachable connection methods such as bolts and nuts, which makes subsequent maintenance and component replacement more convenient compared to traditional fixed connections, extending the service life of the equipment and meeting the needs of efficient, accurate, and multi-specification adaptable testing in modern production.

[0034] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0035] See Figure 1 and Figure 2This PVC pipe inspection drive device includes a conveying device 1 for moving the inspection head. A rotating seat 2 is provided on one side of the conveying device 1 to support and drive the pipe rotation. The rotating seat 2 can be further expanded to improve the stability of the pipe support and rotation. The conveying device 1 includes a bracket 3 fixedly installed on the foundation, providing a stable mounting base for the entire conveying device 1. A working platform 4 is provided on the surface of the bracket 3, serving as a load-bearing component for mounting the subsequent drive structure. Multiple sets of parallel-arranged electrical... The moving screw 5, also known as the electric screw 5, provides precise linear drive power. Two parallel extension rods 6 are mounted on the moving block 7 of the electric screw 5. The moving block 7 moves synchronously with the extension rods 6 as the electric screw 5 drives. The ends of the extension rods 6 are used to mount the detection probe. Through the cooperation of the components in the conveying device 1, the detection head can be stably moved. Combined with the support and rotation of the rotating seat 2 for the pipe, this provides basic structural support for the inspection of PVC pipes. Further components can be added based on this basic structure to further optimize the device's detection performance and adaptability.

[0036] See Figure 3 A vertically extending upright plate 8 is fixed on the moving block 7 of the electric lead screw 5. The upright plate 8 serves as a connecting and adjusting component, providing basic support for the installation and spacing adjustment of the extension rod 6. Two sets of parallel oblong holes 9 are provided on the upper and lower sides of the surface of the upright plate 8. The oblong holes 9 provide movable space for the position adjustment of the extension rod 6. The tail end of the extension rod 6 is fixed in the oblong hole 9 by an arc-shaped locking block 10 and a bolt and nut. The arc-shaped locking block 10 can better fit the tail end structure of the extension rod 6 to ensure the stability of the fixation. The bolt and nut can be inserted... The locking of rod 6 at different positions within the oblong hole 9 allows for flexible adjustment of the distance between the two inserted rods 6 according to testing requirements. This adapts to the installation and positioning needs of testing probes for different specifications of PVC pipes. Simultaneously, this structure works in conjunction with components such as bracket 3, working platform 4, and electric screw 5 in the conveying device 1. With the support and rotation of the pipe by the rotating seat 2, it ensures accurate alignment of the testing probe with the area to be tested on the pipe, further enhancing the flexibility and adaptability of the entire testing drive device.

[0037] See Figure 6 The conveyor device 1 used for transferring the inspection head is provided in two sets, and the two sets of conveyor devices 1 are arranged in a mirror image with reference to the center line of the rotating seat 2 used to support and drive the rotation of the pipe. Figure 6It can be clearly observed that this symmetrical layout allows the two sets of conveying devices 1 to coordinate with the rotating seat 2 in spatial position. Each set of conveying devices 1 includes a bracket 3 fixedly installed on the foundation. The bracket 3 provides stable support for the entire conveying device 1. The surface of the bracket 3 is provided with a working platform 4, which is used to support multiple sets of parallel electric screws 5. The moving block 7 of the electric screw 5 is equipped with two parallel extension rods 6. The ends of the extension rods 6 are used to install detection probes. This structure of two sets of mirror-distributed conveying devices 1 can drive the moving block 7 and the detection probes on the extension rods 6 to adjust their positions synchronously or adaptably through their respective electric screws 5. In conjunction with the support and rotation of the pipe by the rotating seat 2, it ensures that the detection probes are accurately aligned with the area to be detected from both sides of the pipe or the corresponding adapted positions.

[0038] See Figure 4 The rotating base 2, used to support and drive the rotation of the pipe, includes a bracket 11 fixedly installed on the foundation. The bracket 11 provides a stable mounting base for the rotating base 2 as a whole. Figure 4 The load-bearing function of the second support 11 on the upper component can be clearly observed. A drive group 12 is installed above the second support 11, and the number of drive groups 12 is consistent with the number of electric lead screws 5 installed on the surface of the working platform 4 in the conveying device 1. This ensures that the rotating seat 2 and the conveying device 1 are matched in terms of the number of components. Each drive group 12 includes two sets of parallel support rollers 13. The support rollers 13 are used to directly contact and support the pipe. Simultaneously, the midpoint of the line connecting the support rollers 13 is on the same straight line as the axis of the electric lead screw 5. This positional relationship allows the electric lead screw 5 in the conveying device 1 to move. The detection probes on block 7 and extension rod 6 are precisely aligned with the pipe supported by support roller 13. Each support roller 13 is also fixedly connected to drive motor 14 mounted on bracket 2 11 via a shaft. Drive motor 14 can provide power for the rotation of support roller 13, thereby driving the pipe to rotate synchronously. The structure of the rotating seat 2 works in coordination with two sets of conveying devices 1 set mirror images of each other on their center lines. With the detection probes installed at the end of extension rod 6, under the support of bracket 1 3 on conveying device 1 and the transfer action of electric screw 5 on detection head, it provides a guarantee for the stable support, rotation and accurate detection of PVC pipe.

[0039] See Figure 5 The rotating base 2, used to support and drive the pipe rotation, includes not only a second bracket 11 fixedly installed on the foundation, but also a third bracket 15 arranged parallel to the second bracket 11. Figure 5The parallel spatial arrangement of bracket 3 15 and bracket 2 11 is clearly visible, providing stable support for the installation of components in the rotating seat 2. A driven roller 16 is mounted on bracket 3 15, and the number of driven rollers 16 matches the number of support rollers 13 in the drive assembly 12 above bracket 2 11. Furthermore, the driven rollers 16 and support rollers 13 are located on the same axis. This matching number and aligned axis design allows them to work in tandem with the support rollers 13, further enhancing the support effect on the pipe and preventing deviation or swaying during rotation. The support rollers 13 are fixedly connected to the drive motor 14 mounted on bracket 2 11 via shafts, and the drive motor 14 can drive... The support roller 13 rotates, thereby driving the pipe to rotate stably through the cooperation of the support roller 13 and the driven roller 16. This structure works in conjunction with two sets of conveying devices 1 that are mirror images of the center line of the rotating seat 2. The working platform 4 supported by the bracket 3 in the conveying device 1 is equipped with multiple sets of electric screws 5. The moving block 7 of the electric screw 5 drives the extension rod 6 and the end detection probe to move, ensuring that the detection probe can be accurately aligned with the pipe supported and rotated by the rotating seat 2. At the same time, it also provides a structural basis for the subsequent installation of the connecting rod 17 between the coaxial support roller 13 and the driven roller 16, further improving the stability and adaptability of the entire detection drive device and meeting the requirements for support and rotation during the pipe detection process.

[0040] See Figure 5 A connecting rod 17 is installed between the coaxial support roller 13 and driven roller 16 of the rotating seat 2, which connects the two into a whole. The support roller 13 is part of the drive group 12 on the second bracket 11. The number of the support roller 13 is the same as that of the electric lead screw 5 of the conveying device 1 and is connected to the drive motor 14. The driven roller 16 is mounted on the third bracket 15, which is parallel to the second bracket 11. The number of driven rollers is the same as that of the support roller 13 and the axis is aligned. The connecting rod 17 can enhance the rotation synchronization and stability of the two.

[0041] The working principle of this utility model is as follows:

[0042] Initial equipment preparation:

[0043] The PVC pipe to be tested is placed between the support roller 13 and the driven roller 16 of the rotating seat 2. With the help of the parallel support structure of the bracket 2 11 and the bracket 3 15, as well as the connecting action of the connecting rod 17 between the coaxial support roller 13 and the driven roller 16, the pipe is placed stably and the axis of the pipe is matched with the axis of the support roller 13 and the driven roller 16.

[0044] Detector head position adjustment:

[0045] According to the specifications of the pipe to be tested, the electric screw 5 in the conveying device 1 is used to drive the moving block 7 to move along the surface of the working platform 4, thereby adjusting the overall position of the extension rod 6 so that the detection probe installed at the end of the extension rod 6 is initially close to the pipe. Then, by using the waist-shaped hole 9 and the arc-shaped locking block 10 on the vertical plate 8 of the moving block 7, the bolts and nuts are loosened and the tail end of the extension rod 6 is moved along the waist-shaped hole 9 to adjust the distance between the two extension rods 6 until the detection probe is accurately aligned with the area of ​​the pipe to be tested. Finally, the bolts and nuts are tightened to fix the position of the extension rod 6.

[0046] Pipe rotation drive:

[0047] Start the drive motor 14 installed on bracket 2 11. The drive motor 14 drives the support roller 13 to rotate through the shaft. Since the support roller 13 and the driven roller 16 are coaxial and jointly support the pipe, the rotation of the support roller 13 drives the pipe to rotate synchronously. At the same time, the driven roller 16 follows the rotation of the pipe. The connecting rod 17 further ensures the synchronicity of the rotation of the support roller 13 and the driven roller 16, and avoids the pipe from shifting or shaking.

[0048] Detection head transfer and detection:

[0049] During the stable rotation of the pipe, two sets of conveying devices 1, mirrored by the center line of the rotating seat 2, work together to drive the moving block 7 and the detection probe on the extension rod 6 through their respective electric screws 5, and move synchronously or adaptably along the length of the pipe, so that the detection probe can perform a comprehensive scan and detection of the pipe surface and key areas; during this period, the bracket 3 provides stable support for the conveying device 1 to ensure that the detection head is moved accurately and smoothly, and achieves no omissions in the detection in conjunction with the rotating pipe.

[0050] Reset after detection:

[0051] After the pipe inspection is completed, first turn off the drive motor 14, and the support roller 13 and the pipe gradually stop rotating; then drive the moving block 7 and the inspection probe to reset through the electric lead screw 5, loosen the bolts and nuts of the arc-shaped locking block 10, adjust the spacing of the extension rod 6 to the initial state, and finally remove the inspected pipe to complete a single PVC pipe inspection process. The equipment is ready for the next inspection operation.

[0052] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present utility model.
