Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, specifically a high-frequency welded pipe length measuring and weighing device. Background Technology

[0002] High-frequency welded pipe is a type of steel pipe that is formed by heating the edges of a steel strip to a molten state using resistance heat generated by a high-frequency current, and then applying pressure to weld it into shape. To ensure that each pipe is of consistent length and reduce scrap or rework caused by length discrepancies, and to prevent underweighting or overuse of materials, the length and weight of high-frequency welded pipes are often measured during production.

[0003] The patent with publication number CN222418858U discloses a high-frequency welded pipe length measuring and weighing device. This device includes a base, with a weighing mechanism fixedly mounted on the upper end of the base. The weighing mechanism is used to detect the weight of the high-frequency welded pipe. A length measuring mechanism is also fixedly mounted on the upper end of the weighing mechanism to detect the length of the high-frequency welded pipe. The weighing mechanism includes a weighing frame, with two weighing rods slidably mounted inside the frame. Each weighing rod has a weighing spring fitted on its outer surface. One weighing rod has a weighing plate on its outer surface, and the other weighing rod has a weighing clamping plate on its outer surface. This device, through the weighing mechanism, enables accurate weighing of the high-frequency welded pipe, and through the length measuring mechanism, enables accurate length measurement of the high-frequency welded pipe.

[0004] However, the aforementioned length measuring and weighing device still has the following problems in actual use:

[0005] High-frequency welded pipes come in various length specifications (such as 6 meters, 12 meters, etc.). When using a two-end clamping method for length measurement, the unfolded length of the measuring device must not be less than the maximum length of the pipe. However, length measurement is not performed continuously, and the equipment is idle most of the time, stored in the factory. This results in the measuring device occupying a lot of space, causing inconvenience to the factory layout and daily operations. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-frequency welded pipe length measuring and weighing device that does not occupy much space when not in use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-frequency welded pipe length measuring and weighing device, comprising a platform with supporting legs, a support assembly, a lifting mechanism and two monitoring mechanisms connected to the upper surface of the platform, the two monitoring mechanisms being located at opposite ends of the platform, an extension assembly connected to the output end of the lifting mechanism, and several pressing assemblies connected to the other end of the extension assembly, all of which are located above the support assembly, and a moving mechanism connected to the bottom surface of the platform, the output end of the moving mechanism being connected to the support assembly.

[0008] Furthermore, the support assembly includes a V-shaped plate and several No. 1 rollers. The lower end of the V-shaped plate is fixedly connected to the middle of the upper surface of the table. The No. 1 rollers are divided into two groups, and the two groups of No. 1 rollers are rotatably connected to the two sides of the V-shaped plate respectively. One of the No. 1 rollers is connected to the output end of the moving mechanism. Several pressing components are aligned with the center line of the V-shaped plate. Pressure sensors are installed inside some of the No. 1 rollers in the two groups of No. 1 rollers.

[0009] Furthermore, the moving mechanism includes a support block, a motor, and a transmission rod. One end of the support block is fixedly connected to the bottom surface of the table, and the other end of the support block is fixedly connected to the outer wall of the motor. The output shaft of the motor is fixedly connected to one end of the transmission rod, and the other end of the transmission rod passes through the table and the V-shaped plate and is fixedly connected to one end of one of the No. 1 rollers.

[0010] Furthermore, several columns are fixedly connected to the outer walls on both sides of the V-shaped plate, and the lower ends of the columns are fixedly connected to the upper surface of the tabletop.

[0011] Furthermore, the lifting mechanism includes a guide plate and a hydraulic rod. The outer wall of the hydraulic rod is fixedly connected to the upper surface of the platform. The output end of the hydraulic rod passes through the middle of the guide plate and is slidably connected to the guide plate. The upper surface of the guide plate is connected to the extension assembly. One side of the guide plate is also fixedly connected to a V-shaped plate.

[0012] Furthermore, the extension assembly includes a lifting plate and several L-shaped rods. The bottom surface of the lifting plate is fixedly connected to the output end of the hydraulic rod, the upper surface of the lifting plate is fixedly connected to one end of each of the several L-shaped rods, and the other ends of the several L-shaped rods are respectively connected to several pressing assemblies.

[0013] Furthermore, the pressing assembly includes a U-shaped pressure plate and several No. 2 rollers. The middle part of the upper surface of the U-shaped pressure plate is fixedly connected to the end of the L-shaped rod away from the lifting plate. The bottom surface of the U-shaped pressure plate is rotatably connected to several No. 2 rollers. The center of each No. 2 roller is aligned with the center line of the V-shaped plate.

[0014] Furthermore, several guide rods are fixedly connected to the bottom surface of the lifting plate, and the lower ends of the guide rods all pass through the guide plate and are slidably connected to the guide plate.

[0015] Furthermore, the monitoring mechanism includes an L-shaped frame, an infrared sensor receiver, and an infrared sensor transmitter. The lower end of the L-shaped frame and the infrared sensor receiver are both fixedly connected to the platform, and the upper end of the L-shaped frame is fixedly connected to the infrared sensor transmitter, which is aligned with the infrared sensor receiver.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This high-frequency welded pipe length measuring and weighing device has a total length of only the table length (e.g., 1 meter), but can measure high-frequency welded pipes that are several times longer than its own length (e.g., 6 meters, 12 meters, etc.), solving the problem that traditional devices occupy a lot of factory space for a long time because they need to adapt to the maximum pipe length, thus optimizing the factory layout.

[0018] 2. This high-frequency welded pipe length measuring and weighing device drives the welded pipe to move automatically through a moving mechanism. With the infrared sensor monitoring mechanism at both ends, it can automatically record the time difference between the two ends of the welded pipe passing the sensor and calculate the length. No manual operation is required, reducing human error and improving measurement efficiency.

[0019] 3. In this type of high-frequency welded pipe length measuring and weighing device, a pressure sensor is built into part of the No. 1 roller in the support assembly. After the welded pipe is placed, the weight can be directly sensed by the pressure sensor and the data can be transmitted to the control system, realizing the integration of weighing and length measurement and simplifying the operation process.

[0020] 4. This type of high-frequency welded pipe length measuring and weighing device has a lifting mechanism that can adjust the height of the lowering component through a hydraulic rod. Together with a V-shaped plate and rotatable first and second rollers, it can stably clamp high-frequency welded pipes of different diameters, avoiding tilting or leaning due to uneven gravity during movement, thus ensuring measurement stability.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Please see Figures 1-7 A high-frequency welded pipe length measuring and weighing device includes a platform 1 with support legs. The upper surface of the platform 1 is connected to a support assembly, a lifting mechanism and two monitoring mechanisms, which are located at opposite ends of the platform 1. The output end of the lifting mechanism is connected to an extension assembly, and the other end of the extension assembly is connected to several pressing assemblies, which are all located above the support assembly. The bottom surface of the platform 1 is connected to a moving mechanism, and the output end of the moving mechanism is connected to the support assembly.

[0031] As a preferred embodiment of this utility model, the support assembly includes a V-shaped plate 3 and several No. 1 rollers 4. The lower end of the V-shaped plate 3 is fixedly connected to the middle of the upper surface of the platform 1. The several No. 1 rollers 4 are divided into two groups, and the two groups of No. 1 rollers 4 are rotatably connected to the two sides of the V-shaped plate 3 respectively. One of the No. 1 rollers 4 is connected to the output end of the moving mechanism. Several pressing components are aligned with the center line of the V-shaped plate 3. Pressure sensors are provided inside some of the No. 1 rollers 4 in the two groups of No. 1 rollers 4.

[0032] More specifically, by setting up support components, a stable support can be provided for the high-frequency welded pipe from below, while limiting the extension direction of the high-frequency welded pipe so that it will not tilt or deviate at an angle. In addition, with the help of several pressure sensors, the weight of the high-frequency welded pipe resting on the No. 1 roller 4 can be directly measured.

[0033] As a preferred embodiment of this utility model, the moving mechanism includes a support block 13, a motor 14, and a transmission rod 17. One end of the support block 13 is fixedly connected to the bottom surface of the table 1, and the other end of the support block 13 is fixedly connected to the outer wall of the motor 14. The output shaft of the motor 14 is fixedly connected to one end of the transmission rod 17, and the other end of the transmission rod 17 passes through the table 1 and the V-shaped plate 3 and is fixedly connected to one end of one of the rollers 4.

[0034] More specifically, by setting up a moving mechanism, the high-frequency welded pipe can be controlled to move between the support assembly and the pressing assembly when it is necessary to measure the length of the high-frequency welded pipe.

[0035] As a preferred embodiment of this utility model, several columns 2 are fixedly connected to the outer walls on both sides of the V-shaped plate 3, and the lower ends of the columns 2 are fixedly connected to the upper surface of the table 1.

[0036] More specifically, by setting up column 2, the stability of V-shaped plate 3 can be improved.

[0037] As a preferred embodiment of this utility model, the lifting mechanism includes a guide plate 7 and a hydraulic rod 9.

The upper surface of the guide plate 7 is connected to the extension assembly. One side of the guide plate 7 is also fixedly connected to the V-shaped plate 3.

[0038] More specifically, by setting up a lifting mechanism, the height of the pressing component can be changed according to the high-frequency welded pipes of different diameters, thereby cooperating with the support component to clamp the high-frequency welded pipes up and down.

The bottom surface of the lifting plate 8 is fixedly connected to the output end of the hydraulic rod 9, the upper surface of the lifting plate 8 is fixedly connected to one end of each of the plurality of L-shaped rods 11, and the other ends of the plurality of L-shaped rods 11 are respectively connected to a plurality of pressing assemblies.

[0040] More specifically, by setting an extension component, it is possible to ensure that the pressing component does not come into contact with the V-shaped plate 3 after it descends into the V-shaped plate 3.

[0041] As a preferred embodiment of this utility model, the pressing assembly includes a U-shaped pressure plate 12 and a plurality of second rollers 16.

The center of the plurality of second rollers 16 is aligned with the center line of the V-shaped plate 3.

[0042] More specifically, by setting up a pressing component, a downward force can be applied to the high-frequency welded pipe from above, so that the high-frequency welded pipe will not tilt due to uneven gravity when it moves left and right with the moving mechanism.

[0043] As a preferred embodiment of this utility model, a plurality of guide rods 10 are fixedly connected to the bottom surface of the lifting plate 8, and the lower ends of the plurality of guide rods 10 all penetrate through the guide plate 7 and are slidably connected to the guide plate 7.

[0044] More specifically, by setting the guide rod 10, it can work in conjunction with the hydraulic rod 9 to make the force on the lifting plate 8 more even during the lifting process.

[0045] As a preferred embodiment of this utility model, the monitoring mechanism includes an L-shaped frame 5, an infrared sensor receiver 6, and an infrared sensor transmitter 15. The lower end of the L-shaped frame 5 and the infrared sensor receiver 6 are both fixedly connected to the platform 1, and the upper end of the L-shaped frame 5 is fixedly connected to the infrared sensor transmitter 15. The infrared sensor transmitter 15 is aligned with the infrared sensor receiver 6.

[0046] More specifically, by setting up a monitoring mechanism, it is possible to make accurate and timely detections when it is necessary to measure the length of high-frequency welded pipes.

[0047] Working principle:

[0048] like Figures 1 to 7 As shown, when using the high-frequency welded pipe length measuring and weighing device of this utility model, firstly, when the measurement is required, simply place the high-frequency welded pipe to be measured into the opening on the side of the V-shaped plate 3 away from the hydraulic rod 9. At this time, the high-frequency welded pipe can be stably placed on the V-shaped plate 3 due to gravity (it is not necessary to place the high-frequency welded pipe exactly in the middle of the V-shaped plate 3 when placing it, just ensure that the high-frequency welded pipe does not have uneven force at both ends and does not tilt).

[0049] The high-frequency welded pipe placed on the V-shaped plate 3 acts on the No. 1 roller 4 due to gravity. At this time, the pressure sensor located inside part of the No. 1 roller 4 simultaneously senses this weight, and can transmit all of this electrical signal to the external control system (such as a computer display screen, PLC controller, etc., usually equipped with a controller with the same function, this is existing technology and will not be described in detail here). Afterwards, the staff analyzes these data (it can be analyzed manually or automatically by the system, this is also existing technology).

[0050] Next, the length of the high-frequency welded pipe needs to be measured. First, the hydraulic rod 9 is activated, and the output end of the hydraulic rod 9 is retracted, so that the lifting plate 8, guide rod 10, L-shaped rod 11, U-shaped pressure plate 12 and several No. 2 rollers 16 can be lowered together, and then the several No. 2 rollers 16 can be pressed on the top of the high-frequency welded pipe. Together with the several No. 1 rollers 4 on the V-shaped plate 3, the high-frequency welded pipe is clamped, so that the high-frequency welded pipe will not tilt up.

[0051] Then, the motor 14 is turned on. The output shaft of the motor 14 drives the transmission rod 17 to rotate. The rotation of the transmission rod 17 drives one of the first rollers 4 connected to it to rotate. Then, through the friction between the first roller 4 and the second roller 16, the high-frequency welded pipe between them is displaced.

[0052] As the high-frequency welded pipe moves, one end of the high-frequency welded pipe will move into the interior of the V-shaped plate 3. At this time, one end of the high-frequency welded pipe will pass between the infrared sensor receiver 6 and the infrared sensor transmitter 15 located at this end of the V-shaped plate 3. At this time, there is no obstruction between the infrared sensor receiver 6 and the infrared sensor transmitter 15, and the electrical signal can be transmitted to the external control system. Then the control system immediately records the data at this time as zero point.

[0053] Then, motor 14 controls roller 4 to reverse, causing the high-frequency welded pipe to return until the other end of the high-frequency welded pipe passes through another set of infrared sensor receivers 6 and infrared sensor transmitters 15. At this point, the measurement result can be obtained without manual operation.

[0054] After measuring the weight and length of the high-frequency welded pipe through the above steps, the motor 14 controls the high-frequency welded pipe to move back to a position where it will not fall directly. Then, the hydraulic rod 9 can be used to release the second roller 16, and then the high-frequency welded pipe can be taken out and a new high-frequency welded pipe can be placed. After all the high-frequency welded pipes are measured, the total length of the entire device is only the length of the table 1. The table 1 can be one meter long, but it can measure high-frequency welded pipes that are several times longer than its own length, saving space.

[0055] 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.
