Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe detection, in particular to a material discharge buffer device based on a pipe air tightness testing machine. Background Art
[0002] Pipes are widely used in many fields. As a carrier of liquids, gases, powders, etc., their air tightness determines whether the conveying medium will leak, so pipes generally need to undergo an air tightness test before leaving the factory.
[0003] The basic principle of doing an air tightness test is to seal both ends of the pipe, then inflate and pressurize the inside of the pipe, and place the pipe in water to observe whether bubbles are generated. If bubbles are generated, it means that the air tightness does not meet the standard, otherwise it has good air tightness.
[0004] There is an air tightness testing machine in the prior art, which clamps and fixes the pipe to be tested and places the pipe in water for an air tightness test. This air tightness testing machine can adaptively adjust the clamping device for pipes of different specifications to meet the diversity of pipes, and can clamp multiple pipes for testing at the same time. However, the current testing machine does not have a corresponding buffer mechanism when unloading after the air tightness test. Multiple pipes are directly pushed out of the testing machine by the support plate, and the pipes collide freely and fall into the unloading area, which easily causes scratches on the surface of the pipes. Utility Model Content
[0005] The utility model aims to overcome the deficiencies of the prior art and provide a material discharge buffer device based on a pipe air tightness testing machine to solve the technical problem in the prior art that the surface of the pipe is easily scratched when the testing machine discharges the material.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0007] A material unloading buffer device based on a pipe air tightness testing machine, the pipe air tightness testing machine comprises a base, on which a plurality of pipe clamping mechanisms and a plurality of supporting components are fixedly installed along the length direction of the pipe to be tested, the material unloading buffer device is arranged on the supporting component, and the specific arrangement method is as follows:
[0008] The support component comprises a support plate, a plurality of through slots are preset on the surface of the support plate along the length direction of the support plate, and the support component further comprises a plurality of buffer plates, one end of each of the buffer plates is hinged to the inner side of the through slot, the other end of the buffer plate is fixedly connected to one end of a spring through a first rigid line, and the other end of the spring is connected to the base;
[0009] One side of the support plate is hinged to one side of the base, and the bottom of the support plate is driven by a pushing device to drive the support plate to rotate around the hinge point;
[0010] Furthermore, the spring is connected to the base via a second rigid wire, and the second rigid wire is arranged on a fixed base on the base.
[0011] Furthermore, a rigid wire groove is provided on the fixed base, and the second rigid wire passes through the rigid wire groove and is fixed by bolts.
[0012] Furthermore, the buffer plate is an arc-shaped plate, and the curvature of the arc-shaped plate is consistent with the curvature of the pipe to be tested.
[0013] Furthermore, the pushing device is a pushing cylinder, which is fixed on one side of the base, and a push rod of the pushing cylinder is connected to the bottom of the support plate.
[0014] Furthermore, a limiting plate is provided in the through groove for limiting the first rigid wire, and the first rigid wire passes through the limiting plate through a through hole preset in the limiting plate.
[0015] The beneficial effect of the utility model is that, compared with the existing air tightness testing machine, the utility model is provided with a material unloading buffer device on the support plate for placing the pipes, and multiple pipes are placed on the support plate in parallel through the clamping part. After the air tightness test is completed, the support plate is pushed to rotate around the hinge point by the propulsion cylinder fixed to the base, and the multiple pipes are brought closer to the lower material side. Furthermore, a buffer plate is provided on the support plate, and the buffer plate is connected to the base through a rigid line and a spring. In the process of pushing the support plate to rotate, the springs connected to each buffer plate are stretched in sequence. The support plate is in the expanded state, and the buffer plate is pulled to rotate in the through groove. The pipe in contact with the buffer plate gradually moves closer to the next pipe as the buffer plate rotates, until the support plate rotates until all the pipes are abutted and roll down from the unloading end, and the unloading of the pipes is completed. Compared with the method of directly rotating the support plate in the prior art to allow the pipe to roll freely to the unloading end, the buffer plate is arranged in the unloading buffer device. The unloading process is gentler, and each pipe rolls slowly to the next pipe along the buffer plate. There is no mutual collision and friction between the pipes, and the surface of the pipes will not be scratched. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Pipes are widely used in many fields. As a carrier of liquids, gases, powders, etc., their air tightness determines whether the conveying medium will leak, so pipes generally need to undergo an air tightness test before leaving the factory.
[0032] The basic principle of doing an air tightness test is to seal both ends of the pipe, then inflate and pressurize the inside of the pipe, and place the pipe in water to observe whether bubbles are generated. If bubbles are generated, it means that the air tightness does not meet the standard, otherwise it has good air tightness.
[0033] like Figure 1 and Figure 2 It is a pipe air tightness tester in the prior art. Its principle is to place the pipe on the base support plate of the tester, clamp the pipe by the clamping component 2, seal one end of the pipe, and pressurize the other end by inflating the pipe (such as Figure 2 The end shown in the figure), after the pressurization is completed, it is driven by a pushing device (such as Figure 2 The hydraulic cylinder in the middle sinks the entire base into the water tank below. If bubbles are generated in the water tank, the air tightness of the batch of pipes does not meet the standard. Otherwise, they have good air tightness. After the test is completed, the clamping mechanism opens and closes, and the pipes are unloaded to the unloading area by rotating the support plate.
[0034] Example
[0035] In order to solve the problem that the pipes are free to roll down due to the direct rotation of the support plate during unloading, thereby causing scratches between the pipes, this embodiment proposes a unloading buffer device based on a pipe air tightness testing machine, such as Figure 3-9 As shown, the pipe air tightness tester comprises a base 1, on which a plurality of pipe clamping mechanisms 2 and a plurality of supporting components are fixedly mounted along the length direction of the pipe to be tested, and the material discharge buffer device is arranged on the supporting component, and the specific arrangement method is as follows:
[0036] The support component includes a support plate 3, a plurality of through slots 10 are preset on the surface of the support plate 3 along the length direction of the support plate 3, and the support component also includes a plurality of buffer plates 4, one end of each of the buffer plates 4 is hinged to the inner side of the through slot, and the other end of the buffer plate is fixedly connected to one end of a spring 6 through a first rigid line 5, and the other end of the spring 6 is connected to the base 1;
[0037] Preferably, the spring 6 in this embodiment is connected to the base via a second rigid wire 7;
[0038] One side of the support plate 3 is hinged to one side of the base 1, and the bottom of the support plate 3 is pushed by a pushing device to rotate the support plate 3 around the hinge point;
[0039] Preferably, the pushing device in this embodiment is a pushing cylinder 8, which is fixed on the base 1, and the pushing rod 6 of the cylinder is fixedly connected to the bottom of the support plate 3;
[0040] The pipe is placed on the support plate 3. After the clamping mechanism 2 is opened and closed, the unloading operation begins. The side of the support plate 3 hinged with the base 1 is the unloading side. The propulsion cylinder 8 pushes the support plate 3 to rotate around the hinge point with the base 1. When the support plate 3 is in a horizontal state, all the springs 6 are in a natural state. The pipe is in contact with the buffer plate 4 on the support plate 3. In the process of the support plate 3 gradually rotating to a vertical state, each spring 6 gradually changes from a free state to a stretched and extended state, pulling the buffer plate 4 connected to the first rigid line 5. In the process of being pulled, the buffer plate 4 is gradually retracted into the through groove 10. Until the buffer plate is completely retracted into the through groove 10, the pipe is no longer in contact with the buffer plate, but rolls to the unloading side.
[0041] Specifically, in the above process, the other side of the spring 6 is connected to the base 1 through the second rigid wire 7. For each buffer plate 4, the length of the second rigid wire 7 connected thereto is not the same. The length of the second rigid wire 7 corresponding to the buffer plate 4 closest to the blanking side is the longest. Along the direction of the fixed base 9, the length of the second rigid wire 7 corresponding to each buffer plate 4 decreases successively, and the length of the second rigid wire 7 corresponding to the buffer plate 4 closest to one side of the fixed base 9 is the shortest. The purpose of this setting is to control the degree to which each buffer plate 4 is received in the through groove 10 during the rotation process of the support plate 4. The degree of receipt of the buffer plate 4 decreases successively from one side of the fixed base 10 to the blanking side. For the convenience of understanding by those skilled in the art, refer to the attached Figure 3 , the four buffer plates 4 are defined as the first buffer plate 4, the second buffer plate 4, the third buffer plate 4, and the fourth buffer plate 4 from one side of the fixed base 10 to the lower material side. During the rotation of the support plate 3, since the length of the second rigid line 7 connected to the first buffer plate 4 is the shortest, the spring 6 connected to it is stretched and extended first, thereby driving the first buffer plate 4 to gradually enter the through groove 10. During this process, the second buffer plate 4, the third buffer plate 4, and the fourth buffer plate 4 are set at a longer distance from the fixed base 9, and the length of their second rigid line 7 is longer, so the corresponding springs 6 are still in a natural state. Therefore, the three buffer plates 4 do not enter the action until the support plate 3 rotates to a certain extent, the springs 6 connected to the subsequent three buffer plates 4 are stretched and extended, and the subsequent buffer plates 4 will gradually enter the through groove 10 in sequence. The technical effect achieved in this way is that, with the rotation of the support plate 3, the pipe gradually rolls toward the next pipe (the next pipe here refers to the pipe closer to the unloading side), and due to the presence of the buffer plate, the rolling process is very smooth. In the process of the propulsion cylinder 8 pushing the support plate 3 to rotate, the first buffer plate 4 is first retracted into the through groove 10, and the first pipe close to the fixed base 9 rolls toward the unloading side and abuts against the next pipe. Then the second buffer plate 4 is retracted into the through groove, and the first pipe rolls smoothly with the second pipe to the next pipe, and so on, until all the buffer plates 4 are retracted into the through groove 10, and the four pipes roll smoothly to the unloading side along the inclined support plate 3. No free rolling or violent collision occurs in the whole process, and the pipes roll against each other softly and slowly, which solves the technical problem that the pipes are easily collided and scratched during unloading.
[0042] Preferably, the second rigid wire 7 is arranged on a fixed base 9 on the base 1, and a rigid wire groove 12 is arranged on the fixed base 9. The second rigid wire 7 passes through the rigid wire groove 12 and is fixed by bolts. The rigid wire groove 12 is arranged as follows: when the second rigid wire 7 passes through the rigid wire groove 12, the second rigid wire 7 partially protrudes from the rigid wire groove 12. During the actual use of the air tightness testing machine, the length of the second rigid wire 7 may be adjusted according to the different spacing between each buffer plate 4 on the support plate 3. The second rigid wire 7 has some redundant length at the rear end of the rigid wire groove, which can be appropriately adjusted. After the adjustment, it is fixed by bolts to adapt to different sizes of material discharge buffer devices.
[0043] Preferably, the buffer plate 4 is an arc-shaped plate, and its curvature matches the curvature of the corresponding pipe. For pipes of different sizes, the purpose of adapting to the diversified pipes can be achieved by simply replacing the buffer plate 4.
[0044] Preferably, a limiting plate 11 is further provided in the through slot 10, and the limiting plate 11 is used to limit the first rigid wire 5. The first rigid wire 5 passes through the limiting plate 11 through a through hole preset on the limiting plate 11, thereby limiting the freedom of the first rigid wire 5 and preventing it from shaking randomly in the through slot 10. Moreover, the limiting plate 11 is located in the through slot 10 below the horizontal position in the through slot, and will not interfere with the retracting action of the buffer plate 4.
[0045] The material unloading buffer device provided in this embodiment can ensure that after each air tightness test of the pipe is completed, the unloading process is gentle and standardized, there is no free rolling and collision, and each pipe rolls until it abuts against the next pipe before the next buffer plate 4 is taken in. The rolling speed of the pipe is also buffered by the buffer plate 4, and there is no violent collision between the pipes, so as to achieve the purpose of preventing the pipes from being scratched during the unloading process.
[0046] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
