[0002] Special equipment refers to equipment that requires special attention to safety, operating skills, and maintenance during use, such as pressure vessels, elevators, and cranes. Buffer tanks, among others, play a key role in industrial and chemical processing. They are primarily used to stabilize and regulate pressure and flow in fluid systems, reducing the impact of fluctuations and pulses on the system. This not only helps protect downstream equipment from damage caused by overpressure or flow fluctuations, but also improves system operational efficiency and safety. The safety and reliability of buffer tanks are particularly crucial when handling volatile, toxic, or high-pressure gases.

[0003] For example, Chinese patent publication number CN220380895U discloses a device for testing the pressure resistance of metal cans, which relates to the field of metal can testing technology and includes: a metal can testing device base and a testing platform welded to the top of the metal can testing device base; a positioning unit arranged on the bottom surface of the inner wall of the testing platform; a pressing unit fixedly connected to the top of the inner wall of the testing platform; and a testing unit fixedly installed on the bottom surface of the pressing unit, wherein the positioning unit includes a driving part fixedly connected to the bottom surface of the inner wall of the testing platform, and the output end of the driving part is fixedly connected to a clamping part slidably connected to the bottom surface of the inner wall of the testing platform. The utility model fixes the metal can to be tested for pressure resistance by setting the positioning unit, and cooperates with the pressing unit to drive the testing unit to move, so as to perform pressure testing of predetermined specifications on the metal can. In addition, the multi-station design further improves the efficiency of metal can testing, thereby reducing the labor intensity of workers.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1 to 9 The present invention provides a technical solution: a device for testing the compressive performance of special equipment, comprising a base plate 1, two mounting plates 2 are mounted on the top of the base plate 1, one of the mounting plates 2 is slidably adjustable, a clamping portion is mounted between the two mounting plates 2, the clamping portion can fix a test tank 12, a rotating shell 7 is slidably mounted on the outer walls of the two mounting plates 2, a vertically downward straight groove is formed in the bottom of the rotating shell 7, a hammer head 8 is vertically slidably mounted in the straight groove;

[0038] The apparatus further includes a rotating assembly that can rotate the clamping portion and drive the rotating shell 7 to slide synchronously when the clamping portion rotates. The rotating shell 7 can change the angle between the moving path of the hammer head 8 and the tangent line of the hammering point of the test can 12 when sliding, and the hammering distance between the hammer head 8 and the impact point is always the same;

[0039] It also includes a driving assembly that can drive the hammer head 8 to move back and forth;

[0040] The test tank 12 further comprises a detection component, which can detect the degree of deformation of the hammered portion of the test tank 12 .

[0041] See Figure 1 and Figure 8, place the test tank 12 in the corresponding position, drive the two mounting plates 2 closer together through the external structure, during this process the clamping part clamps the test tank 12, and the driving assembly makes the hammer head 8 hammer the test tank 12, and after each hammering, the clamping part is rotated by the rotating assembly, thereby driving the test tank 12 to rotate, and when the test tank 12 rotates, the rotating assembly can drive the rotating shell 7 to slide, thereby rotating the hammer head 8, and the hammering point before and after the rotation of the hammer head 8 is at the same position in space, that is, the point of each hammering is the test tank 12 rotation point. The midpoint of the top line of the curved surface after movement (a straight line parallel to the cylindrical axis at the highest point on the cylindrical arc surface) is named point d in this case for description. When the rotating shell 7 slides synchronously, the tangent angle between the plane of the hammering path of the hammer head 8 and point d will change, that is, each time the rotating shell 7 slides, the point d is hammered at a different angle with the same force. The detection component can be used to compare the data of the test tank 12 before and after the hammering, so as to infer the compressive performance of the test tank 12 at different angles, so as to test the strength of the test tank 12.

[0042] It is worth noting that the hammer head 8 is set to be spherical. The rotation of the test tank 12 and the sliding of the rotating shell 7 are adjusted by the rotating component, so that the hammering direction of the test tank 12 rotates with the center of the ball of the hammer head 8 (that is, the center position of the ball when the hammer head 8 contacts point d) as the center of the circle, so that the hammer head 8 is driven by the driving component to hammer point d, so that the hammer head 8 performs strength testing on the test tank 12 with the same force and different angles, and then the position of point d is detected by the detection component to observe whether it is deformed. This can more realistically simulate the external forces and impacts that may come from different directions and angles in actual working conditions to evaluate the tolerance of the buffer tank.

[0043] It is worth mentioning that the test tank 12 does not deform after a single hammering, indicating that it can withstand the impact force at this angle. In actual situations, multiple or repeated impacts may have a cumulative effect, leading to material fatigue or damage. The same part of the test tank 12 can be hammered multiple times at the same angle, and the deformation of the component can be observed by testing it. The fatigue of the test tank 12 can then be tested to facilitate a more comprehensive assessment of the strength of the test tank 12.

[0044] Furthermore, the rotating assembly includes a circular through hole extending through the outer wall of the mounting plate 2, and a driven inner gear ring 5 is rotatably mounted on the inner wall of the through hole. A first shaft seat 9 is fixedly mounted on the top of the mounting plate 2, and a rotatable rotating gear ring 13 is mounted on the outer wall of the first shaft seat 9, and the rotating gear ring 13 is meshed with the driven inner gear ring 5. The clamping portion can coaxially fix the test tank 12 and the rotating gear ring 13. The rotating shell 7 is mounted between the driven inner gear rings 5 ​​on the two mounting plates 2, and the rotating shell 7 and the hammer head 8 are both arranged along the radial direction of the driven inner gear ring 5.

[0045] Furthermore, the driven internal gear ring 5 can rotate within an angle between zero and ninety degrees.

[0046] See Figure 1 as well as Figure 6 , the first motor fixed to the outer wall of the first shaft seat 9 drives the rotating gear ring 13 to rotate, thereby causing the rotating gear ring 13 to drive the driven inner gear ring 5 to rotate, and then causing the rotating shell 7 to slide on the mounting plate 2, and the axis of the hammering direction of the hammer head 8 will always point to the center of the circle of the driven inner gear ring 5, that is, the rotating shell 7 rotates with the center of the circle of the driven inner gear ring 5 as the center of the circle during the sliding process, and the center of the circle of the driven inner gear ring 5 is aligned with the center of the ball of the hammer head 8 (that is, the center position of the ball when the hammer head 8 contacts point d, as shown in FIG. Figure 9 Point f) in the schematic diagram coincides, so the motion trajectory of the rotating shell 7 is to rotate around this point as the center of the circle, so as to ensure that the hammering distance of the hammer head 8 at different angles is the same, thereby keeping the force of each hammering the same.

[0047] like Figure 7 As shown by the middle dotted line, by driving the rotating gear ring 13 to drive the driven inner gear ring 5 to rotate, the rotating shell 7 and the hammer head 8 are rotated at point f, so that the hammer head 8 hammers the new point d at different angles to eliminate the influence of mechanical fatigue caused by hammering the same point, and the point d before and after each hammering is detected by the detection component to observe the changes after hammering the same position at different angles, and then evaluate the strength of the test tank 12.

[0048] Among them, the rotation range of the driven internal gear ring 5 is between zero and ninety degrees. When the driven internal gear ring 5 rotates ninety degrees, the extension line of the moving direction of the hammer head 8 will be parallel to the tangent line at point d, and there will be no vertical component of force, so there will be no contact with the test tank 12.

[0049] Furthermore, the driving assembly includes a second shaft seat 15 fixedly mounted on the inner bottom of the rotating shell 7, a first rotating shaft 19 is rotatably mounted on the outer wall of the second shaft seat 15, a rotating disc 16 is fixedly mounted on the outer wall of the first rotating shaft 19, and a connecting rod 18 is rotatably mounted on the outer wall of the rotating disc 16 away from the first rotating shaft 19;

[0050] The drive assembly also includes a sliding sleeve 30 slidably mounted on the inner wall of the straight groove of the rotating shell 7, and one end of the connecting rod 18 is rotatably connected to the sliding sleeve 30. A fixed rod 31 is slidably mounted on the inner wall of the sliding sleeve 30. The hammer head 8 is fixedly connected to the end of the fixed rod 31 extending from the sliding sleeve 30. A spring 32 is installed between the other end of the fixed rod 31 and the sliding sleeve 30.

[0051] The driving assembly further includes a driving portion capable of rotating the first rotating shaft 19 and adjusting the rotational speed.

[0052] See Figure 3When the test tank 12 is to be hammered, the first rotating shaft 19 of the driving unit is rotated, thereby driving the connecting rod 18 to rotate, and then the sliding sleeve 30 drives the hammer head 8 to move downward through the connecting rod 18 to complete the hammering of the test tank 12. When the sliding sleeve 30 drives the fixed rod 31 and the hammer head 8 to move downward to hammer the test tank 12, after the hammer head 8 contacts the test tank 12, the fixed rod 31 will be retracted toward the spring 32, causing the spring 32 to be compressed, thereby preventing damage to components such as the connecting rod 18 during the hammering process.

[0053] It is worth mentioning that a buffer ring is provided on the inner wall of the sliding sleeve 30. Under normal conditions, the gravity of the hammer head 8 can enable the fixed rod 31 to overcome the resistance of the buffer ring and place it below the buffer ring, so that the sliding sleeve 30 drives the fixed rod 31 to move downward to hammer the test tank 12. The sliding sleeve 30 and the fixed rod 31 can be regarded as a whole, preventing the spring 32 from being compressed prematurely under the action of inertia during the downward impact, resulting in the dispersion of the impact force, so as to ensure the accuracy of the test data. When the hammer head 8 contacts the test tank 12, the fixed rod 31 will pass over the buffer ring to compress the spring 32, thereby protecting the internal structure.

[0054] Furthermore, the driving part includes a first gear 20 and a second gear 21 fixedly mounted on the outer wall of the first rotating shaft 19, a third shaft seat 22 fixedly mounted on the inner bottom of the rotating shell 7, a second rotating shaft 23 driven by a motor mounted on the outer wall of the third shaft seat 22, a rotating sleeve 26 slidably mounted on the outer wall of the second rotating shaft 23 via a flat key, a third gear 24 and a fourth gear 25 fixedly mounted on the outer wall of the rotating sleeve 26, the third gear 24 can mesh with the first gear 20, the fourth gear 25 can mesh with the second gear 21, and the transmission ratios of the two sets of meshing gears are different;

[0055] The driving unit further includes a magnet 27 fixedly mounted on the outer wall of the rotating sleeve 26 , and an electromagnet 28 is fixedly mounted on the outer wall of the second rotating shaft 23 on one side close to the rotating sleeve 26 .

[0056] See Figure 5 When the hammer head 8 needs to be used to perform hammer testing on the test can 12, the second motor installed on the outer wall of the third shaft seat 22 drives the second rotating shaft 23 to rotate, thereby driving the rotating sleeve 26 to rotate, and then driving the third gear 24 and the fourth gear 25 to rotate. In the initial state, the third gear 24 is engaged with the first gear 20, and the fourth gear 25 is disengaged from the second gear 21. Through the cooperation of the third gear 24 and the first gear 20, the first rotating shaft 19 is rotated, and then the rotating disk 16 is driven to rotate. From the above, it can be seen that when the rotating disk 16 rotates, it will drive the hammer head 8 to hammer the test can 12.

[0057] When the force of the hammering needs to be changed, according to the kinetic energy formula, the faster the speed is, the greater the kinetic energy is under the same mass. Moreover, according to the calculation method of the impact force, increasing the hammering speed of the hammer head 8 can increase the change of momentum, thereby increasing the impact force. Corresponding to the present device, increasing the rotation speed of the rotating disk 16 can make the sliding sleeve 30 and the hammer head 8 have a faster speed when hammering the test can 12, thereby increasing the impact force. The specific implementation method is as follows:

[0058] When the hammering force on the test tank 12 is to be changed, the electromagnet 28 is driven by the external control device, so that the electromagnet 28 attracts the magnet 27, so that the magnet 27 drives the rotating sleeve 26 to move in the direction close to the third shaft seat 22, so that the third gear 24 is disengaged from the first gear 20, and the second gear 21 is engaged with the fourth gear 25, and the transmission ratio of the second gear 21 to the fourth gear 25 is larger, that is, the rotation speed of the first rotating shaft 19 is increased, thereby increasing the rotation speed of the rotating disk 16, and further making the sliding sleeve 30 and the hammer head 8 move downward faster, so as to achieve the purpose of making the hammer head 8 have a greater impact force, so as to facilitate the monitoring of the compressive resistance of the test tank 12 under different impact forces, and to more comprehensively evaluate the strength of the test tank 12.

[0059] Furthermore, the detection component includes a laser transmitter 10 fixedly mounted on the top of one of the first shaft seats 9, and a laser receiver 11 on the top of the other first shaft seat 9. The first shaft seat 9 can emit a laser to the hammered point of the test tank 12, and the laser transmitter 10 can receive the laser beam reflected by the hammered point of the test tank 12.

[0060] See Figure 2 , where dotted line a is the laser beam emitted by the laser emitter 10, dotted line b is the beam reflected by the test can 12, and dotted line c is the hammering path of the hammer head 8. When the test can 12 is not damaged, the beam emitted to point d will be reflected as a mirror image into the laser receiver 11, so that it can be determined whether the laser receiver 11 receives the reflected beam that the test can 12 has been affected during the hammering process of the hammer head 8.

[0061] It is worth mentioning that whether the test tank 12 is in good condition before being impacted can be determined by whether the laser receiver 11 receives the reflected light beam when not being hammered.

[0062] Furthermore, one side of the rotating shell 7 is fixedly connected to one of the driven inner gear rings 5, and a square rod 33 is fixedly installed on the other side of the rotating shell 7. A through hole is opened through the outer wall of the other driven inner gear ring 5 to allow the square rod 33 to slide inside.

[0063] Furthermore, the two mounting plates 2 are respectively a fixed mounting plate 201 and a sliding mounting plate 202. A sliding groove 3 is provided on the top of the base plate 1, and a protrusion 4 that can slide in the sliding groove 3 is fixedly installed on the bottom of the sliding mounting plate 202. A threaded rod 6 is rotatably installed through the outer wall of the fixed mounting plate 201, and a threaded hole is provided through the outer wall of the sliding mounting plate 202, and the threaded rod 6 is threadedly connected to the threaded hole.

[0064] See Figure 6 When the test tank 12 is about to be hammer tested, the operator needs to place the test tank 12 in the fixed sleeve 29 on the fixed mounting plate 201 and tighten the latches 14 on the fixed sleeve 29 so that the annularly distributed latches 14 fix the test tank 12. By rotating the threaded rod 6, the sliding mounting plate 202 moves toward the fixed mounting plate 201, so that the other end of the test tank 12 enters the fixed sleeve 29 corresponding to the sliding mounting plate 202. The operator then tightens the corresponding latch 14 to complete the clamping of the test tank 12, thereby preventing the test tank 12 from deflecting during the subsequent hammer test and ensuring the accuracy of the results.

[0065] Furthermore, one side of the outer wall of the rotating shell 7 is fixedly connected to a driven inner gear ring 5, and the other side of the outer wall of the rotating shell 7 is fixedly installed with a square rod 33. The outer wall of the other driven inner gear ring 5 is penetrated by a slot for the square rod 33 to slide inside.

[0066] See Figure 1 The rotating shell 7 is connected to the driven inner gear ring 5 through a square rod 33. When the driven inner gear ring 5 rotates, the rotating shell 7 is driven to rotate at point d through the square rod 33. The use of the square rod 33 can prevent the rotating shell 7 from rotating, and when the fixed mounting plate 201 is separated from the sliding mounting plate 202, the rotating shell 7 will still be supported by the square rod 33, and one end of it will not be left hanging in the air, thereby ensuring the stability of the entire structure.

[0067] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

[0068] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
