Description

Technical Field

[0001] This invention relates to the field of impact testing technology, and more particularly to impact testing equipment for precision components of shale gas power generation equipment. Background Technology

[0002] The metal pendulum impact testing machine is a classic mechanical property testing device used to determine the impact toughness of metallic materials;

[0003] Shale gas power generation equipment is a comprehensive system that converts unconventional natural gas, such as shale gas, into electricity. The core mission of shale gas power generation equipment is to efficiently and cleanly convert shale gas into reliable electricity. The core parts of shale gas power generation equipment, especially the power generation area, are in an extreme high-temperature environment for a long time during operation. At high temperatures (such as the operating temperature of shale gas equipment), the materials usually have good toughness. When subjected to impact, they will undergo large plastic deformation before breaking, and absorb a high amount of energy.

[0004] When testing materials for shale gas power generation equipment using a metal pendulum impact testing machine, the influence of temperature on the materials must be considered. Otherwise, the test results cannot substantially reflect the material requirements under the operating environment. In existing material heating impact tests, the materials are often heated by a heating device before being transferred to the test area. During this process, the temperature of the tested material is affected by the environment and the transfer time, which seriously restricts the accuracy of the test results and causes inaccurate test results.

[0005] Furthermore, the current metal pendulum impact testing machine, without considering air resistance, is limited by the rotational friction of the bearings in terms of accuracy of the test results. In the testing of materials for shale gas power generation equipment, since the materials need to be tested within a certain temperature range, multiple tests at different temperatures are often required. This necessitates conducting an empty pendulum test before each batch of tests to determine the empty pendulum loss. However, the traditional empty pendulum test interrupts the formal impact testing process, and the waiting and verification time further exacerbates the temperature fluctuations of subsequent samples during the transfer process, forming an inherent contradiction between "temperature accuracy" and "verification efficiency," which seriously affects the accuracy of the test results and the overall testing efficiency. Based on this, an impact testing device for precision components of shale gas power generation equipment is proposed. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing an impact testing device for precision components of shale gas power generation equipment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

The pendulum impact testing machine includes an energy mechanism mounted on a stabilizing frame. The stabilizing frame consists of a counterweight base and a rigid frame. The energy mechanism includes a switchable spindle connected to the rigid frame via a bearing system. The rigid frame is equipped with a pendulum lifting mechanism for smoothly lifting the pendulum and a release mechanism for accurately releasing the pendulum.

[0009] The switchable spindle is connected to two sleeve rings via a switchable control. The sleeve ring on one side is connected to a test pendulum via a pendulum rod, and the sleeve ring on the other side is connected to an empty pendulum bearing test piece. Both the test pendulum and the empty pendulum bearing test piece are equipped with a dial and a pointer for measuring the swing amplitude.

[0010] A sample support is provided on the counterweight base. An automatic sample conveying tray is provided in the inner groove of the sample support. A tray feeding and detection component for testing the sample is provided in the automatic sample conveying tray. A conveying pipeline is provided on the back of the automatic sample conveying tray. A push rod feeding component for conveying the sample is provided in the conveying pipeline. A coil induction heating device for heating the sample is provided outside the conveying pipeline.

[0011] As a preferred embodiment, the switchable control includes a switching cavity opened in the switchable spindle, an inner control column is movably arranged in the switching cavity, magnetic control components for relative movement are arranged at both ends of the inner control column, and locking plugs triggered and controlled by the inner control column are arranged at both ends of the switching cavity.

[0012] As a preferred embodiment, the locking plug includes two limiting blocks disposed opposite to each other in the switching cavity. A limiting slide is provided at the end of the switching cavity. A reset limiting block located in the limiting slide is fixedly connected to the side wall of the limiting block. The two reset limiting blocks are connected by a connecting spring. A docking plug is provided on the side wall of the limiting block that penetrates the side wall of the switching cavity. A mating interface adapted to the docking plug is provided on the inner side wall of the sleeve ring.

[0013] The limiting block is provided with a pressing inclined block on the side near the inner control column, and the end of the inner control column is provided with a pressing inclined surface that is adapted to the pressing inclined block.

[0014] As a preferred embodiment, the magnetic control device includes a magnetic block disposed on the inner wall of the switching cavity, a magnetic control groove is provided on the side wall of the inner control column, and an electromagnetic block is disposed on the inner wall of the magnetic control groove that is attracted to the magnetic block by magnetic force.

[0015] As a preferred embodiment, the automatic sample conveying tray includes a cover, an inner disc fixedly connected to the inner wall of the cover, an outer ring rotatably disposed on the outer wall of the inner disc, a central opening connected to the conveying pipeline on the inner disc, a through-feeding port at the bottom of the central opening, and a feeding port adapted to the feeding port on the inner wall of the outer ring.

[0016] The cover is equipped with a pusher rod, and the output end of the pusher rod is fixedly connected to a guide column. The cover has a discharge port that penetrates the side wall for the guide column to move.

[0017] As a preferred embodiment, a disc drive motor is provided on the counterweight base, and a drive worm is connected to the output end of the disc drive motor. The outer ring body is connected to a worm wheel ring that meshes with the drive worm through a connecting ring.

[0018] As a preferred embodiment, the tray feeding detection assembly includes a U-shaped test cover, with laser receivers and laser emitters arranged on both sides of the U-shaped test cover for detecting the size of the sample notch, and a light-transmitting opening on the cover for laser reflection.

[0019] As a preferred embodiment, the push rod feeding component includes a push seat disposed on a counterweight base, an active push rod disposed on the push seat, and an extrusion push column disposed at the output end of the active push rod for conveying the sample in the conveying pipeline.

[0020] As a preferred embodiment, the coil induction heating device includes an electromagnetic base sleeved on the conveying pipeline, and an electromagnetic coil for electromagnetically heating the sample in the conveying pipeline is disposed inside the electromagnetic base.

[0021] As a preferred embodiment, the stabilizing frame is equipped with a mesh protective cover.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. By integrating the coil induction heating device, this invention can directly heat and keep the sample warm during the sample transport process, effectively avoiding the temperature loss and fluctuation when the sample is transferred from the heating device to the test area in traditional methods. This ensures that the impact test is carried out under conditions that accurately simulate the actual working temperature of shale gas equipment, thereby greatly improving the accuracy and reliability of the test results.

[0024] 2. This invention designs an automatic sample conveying tray and pushing mechanism, realizing automatic and continuous sample conveying and precise positioning. It integrates a tray detection component (laser detection) that can automatically detect the orientation of the sample notch, ensuring that the sample is tested in the correct state, reducing human intervention and operational errors. The entire process from heating, conveying, testing to positioning is automated, which greatly shortens the interval time of a single test and improves the efficiency of batch testing.

[0025] 3. This invention, through the design of a switchable spindle and dual pendulums (test pendulum and empty pendulum bearing test piece), combined with a magnetically controlled switching mechanism, allows for quick and convenient switching between the test pendulum and the empty pendulum test piece. It enables simultaneous empty pendulum testing during the sample preparation stage to quickly verify whether the friction state of the bearing system meets the standard without interrupting the formal impact testing process. By integrating empty pendulum verification into the testing process, this invention solves the problem that traditional methods require empty pendulum testing before each batch of tests, which seriously affects testing efficiency. While ensuring data accuracy, it optimizes testing efficiency.

[0026] 4. This invention, through the coordinated design of an integrated online heating and conveying system (coil induction heating device, conveying pipeline, automatic sample conveying tray) and a switchable dual pendulum calibration system (switchable spindle, test pendulum, and empty pendulum bearing test piece), utilizes the necessary time required for sample conveying, heating, heat preservation, and automatic positioning preparation to simultaneously perform empty pendulum calibration of the bearing system. This eliminates the extra testing time required for the empty pendulum calibration process, which originally caused an efficiency bottleneck, and avoids sample temperature drop caused by calibration waiting. Thus, under the premise of high efficiency, it simultaneously ensures the "temperature authenticity" and "data reliability" of the impact test. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] Example, refer to Figures 1 to 10 Impact testing equipment for precision components of shale gas power generation equipment, including a pendulum impact testing machine, the pendulum impact testing machine including an energy mechanism mounted on a stabilizing frame, the stabilizing frame consisting of a counterweight base 1 and a rigid frame 2, and a mesh protective cover 38 provided on the stabilizing frame;

[0042] The energy mechanism includes a switchable spindle 3 connected to a rigid frame 2 via a bearing system. The rigid frame 2 is equipped with a pendulum lifting mechanism for smoothly lifting the pendulum and a pendulum release mechanism for accurately releasing the pendulum. The release mechanism and the pendulum lifting mechanism are existing technologies and will not be described in detail here.

[0043] The switchable spindle 3 is connected to two sleeve rings 4 via a switchable control. The switchable control includes a switching cavity 11 opened inside the switchable spindle 3. An inner control post 12 is movably arranged inside the switching cavity 11. Magnetic controls that control the relative movement of the inner control post 12 are arranged at both ends of the inner control post 12. Locking plugs that are triggered and controlled by the inner control post 12 are arranged at both ends of the switching cavity 11. Under the action of the magnetic controls, the inner control post 12 can be driven to move horizontally, thereby realizing the switching and opening of the locking plugs on both sides, realizing the locking between the sleeve rings 4, and thus realizing the switching of the switchable spindle 3 between the test pendulum 6 and the empty pendulum bearing test piece 7.

[0044] Furthermore, the locking plug includes two limiting blocks 13 disposed opposite to each other in the switching cavity 11. A limiting slide is opened at the end of the switching cavity 11. A reset limiting block 14 located in the limiting slide is fixedly connected to the side wall of the limiting block 13. The two reset limiting blocks 14 are connected by a connecting spring. A docking plug 15 penetrating the side wall of the switching cavity 11 is provided on the side wall of the limiting block 13. A mating interface 16 adapted to the docking plug 15 is opened on the inner side wall of the sleeve ring 4.

[0045] The limiting pressure block 13 is provided with a pressing inclined block 17 on the side near the inner control column 12. The end of the inner control column 12 is provided with a pressing inclined surface 18 that is adapted to the pressing inclined block 17. When the inner control column 12 moves, it will drive the pressing inclined block 17 to move outward, thereby realizing the docking between the docking plug 15 and the docking interface 16 on the sleeve ring 4.

[0046] Furthermore, the magnetic control device includes a magnetic block 20 disposed on the inner wall of the switching cavity 11, and a magnetic control groove is provided on the side wall of the inner control column 12. An electromagnetic block 19 is disposed on the inner wall of the magnetic control groove and is attracted to the magnetic block 20 by magnetic force. The electromagnetic block 19 is existing technology and will not be described in detail here. The magnetic control devices on both sides control the inner control column 12 in opposite directions.

[0047] The sleeve ring 4 on one side is connected to the test pendulum 6 via the pendulum rod 5. The sleeve ring 4 on the other side is connected to the empty pendulum bearing test piece 7. Both the test pendulum 6 and the empty pendulum bearing test piece 7 are equipped with a scale 8 for measuring the swing amplitude and a pointer. The scale 8 is fixedly installed on a rigid frame. The test pendulum 6 and the empty pendulum bearing test piece 7 share the same set of lifting mechanism for smoothly lifting the pendulum and release mechanism for accurately releasing the pendulum.

[0048] It is worth noting that the impact test process of the test pendulum 6 is existing technology. In this solution, by setting up a separate empty pendulum bearing test piece 7, it is possible to switch the test pendulum 6 to the empty pendulum bearing test piece 7 during the sample preparation stage by switching the controllable switch. An empty pendulum test is then performed using the empty pendulum bearing test piece 7. By observing whether the height of the pointer moving during the rotation of the empty pendulum bearing test piece 7 is always the same, it can be determined whether the bearing friction at this stage meets the standard. This ensures that the bearing can be reliably tested before each pendulum impact test.

[0049] When conducting impact tests on materials for shale gas power generation equipment, the system initiates a collaborative workflow: On one hand, the sample is transported forward by the extrusion pusher 35 driven by the active pusher 34, and heated and kept warm at the coil induction heating device; on the other hand, taking advantage of the time window of this sample preparation stage, the magnetic control is used to switch to the pendulum bearing test piece 7 for a pendulum test to verify whether the bearing friction at this stage meets the standard.

[0050] After confirming that the bearings are in good condition and the specimen is ready, the system again switches the internal control column 12 via the magnetic control to achieve docking with the test pendulum 6. Subsequently, the heated and heat-preserved specimen is automatically transported and precisely positioned on the specimen support 9 for immediate impact testing.

[0051] Through the above process, the two key preparatory steps of sample heating and transport and bearing pendulum calibration can be completed simultaneously and in parallel, which not only greatly shortens the cycle of a single test, but also ensures that the impact test is carried out under the premise of the most realistic sample temperature and the most reliable equipment condition.

[0052] A sample support 9 is provided on the counterweight base 1. An adjustable stop block is provided on the sample support 9 for positioning the sample after delivery. An automatic sample delivery disc is provided in the inner groove of the sample support 9. Further, the automatic sample delivery disc includes a cover 21. An inner disc 22 is fixedly connected to the inner wall of the cover 21. An outer ring 23 is rotatably provided on the outer wall of the inner disc 22. A central opening 24 connected to the delivery pipeline 10 is opened on the inner disc 22. A through discharge port 25 is opened at the bottom of the central opening 24. A feeding port 26 adapted to the discharge port 25 is opened on the inner wall of the outer ring 23.

[0053] The cover 21 is provided with a push electric push rod 27, and the output end of the push electric push rod 27 is fixedly connected to a push guide column. The cover 21 has a discharge port 29 that penetrates the side wall for the push guide column to move.

[0054] Furthermore, a disc drive motor 30 is provided on the counterweight base 1. The output end of the disc drive motor 30 is connected to a drive worm 28. The outer ring body 23 is connected to a worm wheel ring 31 that meshes with the drive worm 28 through a connecting ring. Under the drive of the disc drive motor 30, and under the action of the drive worm 28 and the worm wheel ring 31, the outer ring body 23 is driven to rotate. During the rotation, the sample is gradually transported from below to the discharge port 29 on the cover body 21 above.

[0055] The automatic sample conveying tray is equipped with a tray delivery and detection assembly for testing the sample. The tray delivery and detection assembly includes a U-shaped test cover 32. Laser receivers and laser emitters are set on both sides of the U-shaped test cover 32 to detect the size of the sample notch. A light-transmitting port 33 for laser reflection is opened on the cover 21. The laser receivers and laser emitters set on the U-shaped test cover 32 can detect the orientation of the sample notch to ensure that the sample delivered to the sample support 9 is in the correct test state.

[0056] The sample automatic conveying tray is provided with a conveying pipeline 10 on the back. The conveying pipeline 10 is provided with a push rod feeding component for conveying the sample. The push rod feeding component includes a push seat provided on the counterweight base 1. The push seat is provided with an active push rod 34. The output end of the active push rod 34 is provided with a compression push column 35 for conveying the sample in the conveying pipeline 10.

[0057] The outside of the conveying pipeline 10 is provided with a coil induction heating device for heating the sample. The coil induction heating device includes an electromagnetic base 36 sleeved on the conveying pipeline 10, and an electromagnetic coil 37 for electromagnetically heating the sample in the conveying pipeline 10 is provided inside the electromagnetic base 36.

[0058] In this invention, when conducting impact tests on materials for shale gas power generation equipment, the materials are processed, and the temperature required for the sample material is controlled by setting the coil induction heating device. The same batch of sample materials to be tested is placed into the conveying pipeline 10, and the sample is conveyed forward by the extrusion push column 35 driven by the active push rod 34.

[0059] When the sample moves to the induction heating device, the energy generated by the electromagnetic coil 37 is concentrated to heat the sample material that has moved there. When the sample temperature reaches the predetermined temperature, the sample is kept warm through the delivery pipeline 10.

[0060] During this process, by controlling the magnetic control, the locking plug at the sleeve ring 4 connected to the test pendulum 6 is released, and the locking plug at the sleeve ring 4 connected to the empty pendulum bearing test piece 7 is docked. An empty pendulum test is performed through the empty pendulum bearing test piece 7. By observing whether the height of the pointer moving during the rotation of the empty pendulum bearing test piece 7 is always the same, it can be determined whether the bearing friction at this stage meets the standard. After ensuring that the bearing friction meets the standard, the inner control column 12 is switched again by controlling the magnetic control to achieve docking with the test pendulum 6.

[0061] The extrusion pusher 35 driven by the active pusher 34 moves forward to transport the sample to the center port 24. The sample is then transported to the feeding port 26 through the bottom discharge port 25. At this time, driven by the disc drive motor 30, the outer ring body 23 is rotated by the drive worm 28 and worm wheel ring 31. During the rotation, the sample is transported to the discharge port 29 on the cover 21 above. During the transport process, when the sample moves to the light-transmitting port 33, the laser receiver and laser emitter set on the U-shaped test cover 32 will detect the orientation of the notch of the sample to ensure that the sample transported to the sample support 9 is in the correct test state.

[0062] When the sample moves to the discharge port 29, the push rod 27, connected to the output end of the push column, will accurately transport the sample to the sample support 9 to realize the pendulum impact test and explore the performance of the sample at the predetermined temperature.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
