DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work 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 compression performance detection device for special equipment, comprising a bottom plate 1, two mounting plates 2 are installed on the top of the bottom plate 1, and one of the mounting plates 2 can be slidably adjusted, a clamping part is installed between the two mounting plates 2, and the clamping part can fix the test tank 12, and a rotating shell 7 is slidably installed on the outer walls of the two mounting plates 2, and a vertically downward straight groove is opened at the bottom of the rotating shell 7, and a hammer head 8 is vertically slidably installed in the straight groove;

[0038] It also includes a rotating assembly, which can rotate the clamping part and drive the rotating shell 7 to slide synchronously when the clamping part rotates. When the rotating shell 7 slides, it can change the angle between the moving route of the hammer head 8 and the tangent line of the hammering point of the test tank 12, and the hammering distance between the hammer head 8 and the impact point is always the same;

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

[0040] The test tank 12 also includes a detection component, which can detect the degree of deformation of the hammered part of the test tank 12.

[0041] See also Figure 1 and Figure 8, place the test tank 12 at the corresponding position, drive the two mounting plates 2 to approach each other through the external structure, during which the clamping part clamps the test tank 12, and the driving component is used to make the hammer head 8 hammer the test tank 12, and after each hammering, the clamping part is rotated by the rotating component, thereby driving the test tank 12 to rotate, and when the test tank 12 rotates, the rotating component can drive the rotating shell 7 to slide, thereby rotating the hammer head 8, and the hammering point before and after the hammering head 8 rotates 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 axis of the cylinder 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 different angles with the same force. The data of the test tank 12 before and after the hammering can be compared through the detection component, 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. The hammer head 8 is driven by the driving component to hammer the 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 be received from different directions and angles in actual working conditions, so as to evaluate the tolerance of the buffer tank.

[0043] It is worth mentioning that the test tank 12 does not deform after one 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. Then, the fatigue of the test tank 12 can be tested, so as to facilitate a more comprehensive evaluation 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, 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 also 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, so that the rotating gear ring 13 drives the driven inner gear ring 5 to rotate, and then the rotating shell 7 slides on the mounting plate 2, and the axis of the hammering direction of the hammer head 8 always points to the center of the driven inner gear ring 5, that is, the rotating shell 7 rotates with the center of the driven inner gear ring 5 as the center of the circle during the sliding process, and the center of the driven inner gear ring 5 and the center of the ball of the above-mentioned hammer head 8 (that is, the center position of the ball when the hammer head 8 contacts point d, as shown in FIG. Fig. 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 dotted line in the middle, the driven inner gear ring 5 is driven to rotate by driving the rotating gear ring 13, so that the rotating shell 7 and the hammer head 8 rotate at point f, and 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] 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 travel direction of the hammer head 8 will be parallel to the tangent line at point d, and there will be no vertical force component, so it will not contact 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 through 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 driving 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 fixing rod 31 is slidably mounted on the inner wall of the sliding sleeve 30, the hammer head 8 is fixedly connected to one end of the fixing rod 31 extending out of the sliding sleeve 30, and a spring 32 is installed between the other end of the fixing 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 rotation speed.

[0052] See also 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 retract toward the spring 32, compressing the spring 32, thereby preventing damage to the connecting rod 18 and other components 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 and the fixed rod 31 can be regarded as a whole in the process of driving the fixed rod 31 to move downward to hammer the test tank 12, thereby 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] Further, 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 is fixedly mounted on the inner bottom of the rotating shell 7, a second rotating shaft 23 driven by a motor is mounted on the outer wall of the third shaft seat 22, a rotating sleeve 26 is slidably mounted on the outer wall of the second rotating shaft 23 through a flat key, a third gear 24 and a fourth gear 25 are 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 one side of the second rotating shaft 23 close to the rotating sleeve 26 .

[0056] See also Figure 5 When the hammer head 8 is needed to perform hammer detection 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 tank 12, thereby making its impact force greater. 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, and 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 meshed 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 also Figure 2 , wherein the dotted line a is the laser beam emitted by the laser transmitter 10, the dotted line b is the beam reflected by the test tank 12, and the dotted line c is the hammering path of the hammer head 8. When the test tank 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 judged whether the laser receiver 11 receives the reflected beam to cause an impact on the test tank 12 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 formed 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 at the top of the base plate 1, a protrusion 4 which can slide in the sliding groove 3 is fixedly installed at 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, 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 also 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 latch 14 on the fixed sleeve 29 so that the annularly distributed latch 14 fixes 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 to prevent deviation during the subsequent hammer test of the test tank 12, so as to ensure the accuracy of the result.

[0065] Furthermore, one side of the outer wall of the rotating shell 7 is fixedly connected to a driven inner gear ring 5, and a square rod 33 is fixedly installed on the outer wall of the rotating shell 7 on the other side. A groove is penetrated through the outer wall of the other driven inner gear ring 5 to allow the square rod 33 to slide inside.

[0066] See also 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 square rod 33 is used to prevent the rotating shell 7 from rotating. When the fixed mounting plate 201 is separated from the sliding mounting plate 202, the rotating shell 7 is also supported by the square rod 33, and one end of the rotating shell 7 is not left hanging in the air, so as to ensure 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 the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0068] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
