Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe detection, in particular to a pipe drop tester. Background Art
[0002] The pipe drop test, as a crucial mechanical property testing method, plays an indispensable role in the field of pipe quality control. It is specifically designed to simulate the scenario of an accidental drop of the pipe to evaluate its performance and safety reliability.
[0003] Traditional methods for performing pipe drop tests often require manual handling of the pipe, lifting it to a predetermined height and then releasing it to allow it to fall freely. During this process, a second observer closely monitors the pipe's reaction to landing, inspecting it for signs of failure, such as cracking or deformation, and recording the relevant data in detail for subsequent analysis. While this method is intuitive and effective to a certain extent, its limitations and shortcomings become apparent when testing large-scale or batch pipes. When drop testing multiple pipes simultaneously is required, purely manual operation is not only time-consuming and labor-intensive, but also makes it difficult to ensure that each pipe is precisely lifted to the same height, introducing human error. This error can affect the accuracy and consistency of test results, making the final conclusions unreliable. Furthermore, this purely manual operation limits test efficiency, especially when dealing with large numbers of samples. This inefficient testing method significantly prolongs the entire testing cycle, increasing the time and cost burden. Utility Model Content
[0004] The utility model discloses a pipe drop tester, which solves the problem that traditional pipe drop tests rely on manual operation, are time-consuming and labor-intensive when faced with large-scale tests, and are difficult to ensure accuracy and consistency, thereby affecting test results and increasing test cycles and cost burdens.
[0005] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions:
[0006] The top end face of the lifting post is fixed with a lifting power of 1.25 and a lifting power of 1.25 for lifting the lifting post is a bottom end of the lifting post, and the bottom end of the lifting post is fixed with a lifting power of 1.25 and a lifting power of 2.25 for lifting the lifting post.
[0007] Compared with the prior art, the present invention has the following beneficial effects:
[0008] Place the pipe to be tested between the two placement seats, use the first driving assembly to drive the movable cylinder to move down to the bottom along the support column, at this time the clamping assembly will rotate to between the two placement seats, use the clamping assembly to clamp the pipe between the two placement seats, and then use the first driving assembly to drive the movable cylinder to move up to the top again. At this time, the clamping assembly is located just above the test plate, and the clamping assembly is used to loosen the pipe, allowing the pipe to perform free fall motion, so that the drop test of the pipe can be completed; when multiple pipes need to be tested at the same time, the staff can move to the clamping assembly on the movable cylinder to test the pipe at the same time. In any process of the holding assembly releasing the pipe, the next pipe to be tested is placed between the two placement seats; in any process of the clamping assembly releasing the previous pipe to the movable cylinder moving down to clamp the next pipe, the test result of the previous pipe can be recorded and the top surface of the test plate can be cleaned to prevent the test of the next pipe from being affected. By coordinating the above-mentioned device with manual staggered operation, the detection time of multiple pipes can be saved, and the detection efficiency is effectively improved. At the same time, only one staff member is required to complete the detection operation of multiple pipes in the whole process, saving labor costs. The utility model is highly practical. By setting the support column, the movable cylinder, the first drive assembly and the clamping assembly, it can automatically realize the fixed-point drop detection of multiple pipes, effectively avoiding the influence of manual error on the detection result. At the same time, the placement seat and the test plate are set at different positions, and the first drive assembly and the clamping assembly are used to make the device cooperate with the manual staggered operation, effectively saving the detection time of multiple pipes, saving labor costs, and improving the detection efficiency.

[0016] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.
[0017] like Figure 1 、 Figure 2 and Figure 3As shown, the utility model provides a pipe drop tester, comprising a horizontally arranged bottom plate 1, a support frame 2 is fixed to one side of the top surface of the bottom plate 1, two placement seats 3 for placing pipes are fixed on the top surface of the bottom plate 1 away from the support frame 2, the top surfaces of the two placement seats 3 are both arc-shaped, and the two placement seats 3 are arranged in parallel and spaced apart, a horizontal test plate 8 is also fixed to the top surface of the bottom plate 1, and the test plate 8 is located just in front of the support frame 2; a vertical support column 4 is fixed on the support frame 2, the support column 4 is cylindrical, and the bottom end of the support column 4 is fixedly connected to the bottom plate 1, supporting A vertical movable cylinder 41 is sleeved on the support column 4. A horizontal support bar 5 is fixed to the side of the movable cylinder 41 facing away from the support frame 2. One end of the support bar 5 extends in a direction away from the movable cylinder 41. A clamping assembly is provided at the extended end of the support bar 5. The support frame 2 is provided with a first driving assembly for driving the movable cylinder 41 to move up and down along the support column 4 while rotating back and forth 90 degrees. When the movable cylinder 41 moves to the bottom, the clamping assembly rotates to between the two placement seats 3. Correspondingly, when the movable cylinder 41 moves to the top, the clamping assembly is located directly above the test plate 8. Furthermore, the test plate 8 and the base plate 1 can be detachably connected by bolts to facilitate replacement of the test plate 8. By replacing the test plate 8 with a different material, it is possible to simulate the scenario of the pipe falling in different environments, thereby obtaining more comprehensive test results.
[0018] like Figure 1 、 Figure 2 and Figure 3As shown, the support column 4 is also provided with a movable disk 42, the bottom surface of the movable disk 42 is fixedly connected to the top surface of the movable cylinder 41, and the diameter of the movable disk 42 is larger than the diameter of the movable cylinder 41; the first driving assembly includes a first motor 6 vertically fixed to the support frame 2, the output end of the first motor 6 is fixed with a screw rod 61 arranged parallel to the support column 4, the two ends of the screw rod 61 are respectively rotatably connected to the bottom plate 1 and the support frame 2, the screw rod 61 is threadedly connected to a movable block 62, and the movable block 62 is fixed with a support member 6 on one side close to the support column 4. 3. The side of the support member 63 facing away from the movable block 62 is engaged with one side of the movable disk 42, and the support member 63 does not affect the rotation of the movable disk 42 around its own axis. It also includes a support rod 7 vertically fixed to the bottom plate 1, and the support rod 7 is arranged away from the placement seat 3. A clamping block 71 is fixed to the top of the side of the support rod 7 close to the support column 4. The surface of the movable cylinder 41 is provided with a slide groove 43 that is engaged with the clamping block 71. The clamping block 71 and the slide groove 43 can enable the movable cylinder 41 to move up and down along the support column 4 while rotating back and forth 90 degrees. When the first motor 6 is started, the output end of the first motor 6 drives the screw rod 61 to rotate around its own axis, which can drive the support member 63 up and down through the movable block 62, thereby driving the movable cylinder 41 up and down along the support column 4 through the movable disk 42. During the process of the movable cylinder 41 moving up and down, due to the arrangement of the slide groove 43 and the clamping block 71, the movable cylinder 41 can move up and down while rotating back and forth 90 degrees.
[0019] like Figure 4 As shown, the slide groove 43 includes an oblique groove 431, a first vertical groove 432 and a second vertical groove 433. The first vertical groove 432 and the second vertical groove 433 are respectively arranged at both ends of the oblique groove 431, and the first vertical groove 432 and the second vertical groove 433 are respectively located at the top and bottom of the movable cylinder 41. The line connecting the first vertical groove 432 and the axis of the movable cylinder 41 and the projection of the line connecting the second vertical groove 433 and the axis of the movable cylinder 41 in the vertical direction are perpendicular to each other. When the movable cylinder 41 is at the top and moves downward, the blocking block 71 first engages with the second vertical slot 433. As the movable cylinder 41 continues to move downward, the blocking block will enter the inclined slot 431 from the second vertical slot 433, which can drive the movable cylinder 41 to rotate. Since the line connecting the first vertical slot 432 and the axis of the movable cylinder 41 and the projection of the line connecting the second vertical slot 433 and the axis of the movable cylinder 41 in the vertical direction are perpendicular to each other, the movable cylinder 41 can just rotate at an angle of ninety degrees; accordingly, when the movable cylinder 41 is at the bottom and moves upward, the blocking block 71 will sequentially engage with the first vertical slot 432, the inclined slot 431 and the second vertical slot 433, thereby completing the back and forth rotation operation of the movable cylinder 41; further, by setting the length of the first vertical slot 432 to be longer, the movable cylinder 41 can move a greater distance in the vertical direction, thereby performing more precise control over the height of the pipe falling.
[0020] like Figure 6 As shown, the top and bottom surfaces of the movable disk 42 are each provided with an annular groove 421. The side of the support member 63 facing away from the movable block 62 is provided with an arcuate slot 631 corresponding to one side of the movable disk 42. The slot 631 runs through both sides of the support member 63, and a protrusion 632 corresponding to the groove 421 is provided in the slot 631. The provision of the arcuate slot 631 enables the movable disk 42 to rotate freely within the support member 63. The provision of the groove 421 and the protrusion 632 enables the movable disk 42 to be engaged with the support member 63, allowing the movable cylinder 41 to move up and down with the support member 63.
[0021] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the clamping assembly includes two connectors 51 movably mounted on the extended end of the support bar 5. The two connectors 51 are symmetrically spaced and each has an inverted V-shaped structure. Two vertical clamping blocks 52 are fixed to the bottom end of each connector 51, and the two clamping blocks 52 are located at the two V-shaped feet of the corresponding connector 51. The opposing sides of the clamping blocks 52 on different connectors 51 are both curved. The extended end of the support bar 5 is equipped with a second drive assembly for driving the two connectors 51 towards or away from each other. When the movable cylinder 41 moves to the bottom, the two connectors 51 are located on either side of the pipe to be inspected. The second drive assembly then drives the two connectors 51 towards each other, securing the pipe between the curved surfaces of the four clamping blocks 52. Furthermore, the arrangement of four clamping blocks 52 provides a more stable fixation on the pipe than with two conventional clamping blocks 52, thereby preventing the pipe from tilting and falling from one end due to an unstable center of gravity during fixation, causing the pipe to fail inspection.
[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the second drive assembly includes a second motor 53 horizontally fixed to the extended end of the support bar 5. A horizontal bidirectional screw 54 is fixed to the output end of the second motor 53. The bidirectional screw 54 is located inside the support bar 5 and is rotatably connected to the support bar 5. Two symmetrical sliders 55 are threadedly connected to the bidirectional screw 54. The bottom ends of the sliders 55 are fixedly connected to the top ends of the corresponding connecting members 51. A cavity 56 is provided in the support bar 5 for the two sliders 55 to move. When the second motor 53 is started, the output end of the second motor 53 drives the bidirectional screw 54 to rotate around its own axis, which can drive the two sliders 55 to move closer to or farther from each other, thereby driving the two connecting members 51 to move closer to or farther from each other, thereby achieving the fixing and loosening operations of the pipe.
[0023] like Figure 5As shown, the curved surfaces of the four clamping blocks 52 are each secured with a rubber layer 521. The provision of the rubber layer 521 not only prevents the four clamping blocks 52 from scratching the surface of the pipe when clamping and securing the pipe, thereby affecting the test results, but also increases the friction between the pipe and the four clamping blocks 52, thereby securing the pipe more securely.
[0024] When in use, the pipe to be tested is placed between the two placement seats 3, and the first motor 6 is started. The output end of the first motor 6 drives the screw rod 61 to rotate around its own axis, which can drive the support member 63 to move downward through the movable block 62, thereby driving the movable cylinder 41 to move downward along the support column 4 through the movable disk 42; in the process of the movable cylinder 41 moving up and down, the clamping block 71 is first engaged with the second vertical groove 433, and as the movable cylinder 41 continues to move downward, the clamping block will enter the inclined groove 431 from the second vertical groove 433, so that the movable cylinder 4 can be driven to move downward. 1 rotates, because the projections of the line connecting the first vertical slot 432 and the axis of the movable cylinder 41 and the line connecting the second vertical slot 433 and the axis of the movable cylinder 41 in the vertical direction are perpendicular to each other, the movable cylinder 41 can just rotate ninety degrees; at this time, the two connecting members 51 will be located on both sides of the pipe to be tested, and then the second motor 53 is used to drive the two connecting members 51 to move closer to each other, so that the pipe can be fixed between the arc surfaces of the four clamping blocks 52; then, the first motor 6 is used again to drive the movable cylinder 41 to move upward, and during the upward movement The clamping block 71 will engage with the first vertical slot 432, the inclined slot 431 and the second vertical slot 433 in sequence, thereby completing the back-and-forth rotation operation of the movable cylinder 41; at this time, the clamping assembly is located directly above the test plate 8, and then the second motor 53 is used to drive the two connecting members 51 away from each other, loosening the pipe, allowing the pipe to perform free fall motion, thereby completing the drop test of the pipe; when multiple pipes need to be tested simultaneously, the staff can place the next pipe to be tested between the two placement seats 3 during any process from the movable cylinder 41 moving up to the clamping assembly to loosen the pipe; and can also record the test results of the previous pipe and clean the top surface of the test plate 8 during any process from the clamping assembly loosening the previous pipe to the movable cylinder 41 moving down to clamp the next pipe to prevent affecting the test of the next pipe. By cooperating with the manual staggered operation, the testing time of multiple pipes can be saved, and the testing efficiency is effectively improved. At the same time, only one staff member is required to complete the testing operations of multiple pipes during the entire process, saving labor costs.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
