Description

Technical Field

[0001] The invention relates to the technical field of medical rubber product detection, and in particular to an ultrasonic detection device and method for a rubber seismic isolation bearing. Background Art

[0002] In the medical industry, during the operation of the ventilator, components such as motors and fans will produce continuous vibrations. If these vibrations are not effectively isolated, they will directly affect the performance of the equipment. At the same time, medical equipment that requires high stability, such as operating tables, dialysis machines, and hyperbaric oxygen chambers, are particularly important for their seismic resistance during use. Rubber seismic isolation bearings are required on these devices. Rubber seismic isolation bearings are made by alternating thin steel plates and thin rubber plates and vulcanizing them at high temperature and high pressure. Rubber seismic isolation bearings can not only ensure vertical stiffness and bearing capacity, but also greatly reduce horizontal stiffness. During the vulcanization process, foreign matter such as air can easily enter, thereby affecting the vulcanization effect. For example, air entering will cause holes in the rubber layer, which will seriously affect the mechanical properties and safety of the rubber seismic isolation bearings. Therefore, it is necessary to detect internal defects in the rubber layer of the vulcanized rubber isolation bearings.

[0003] Since medical rubber seismic isolation bearings have the characteristics of multiple vulcanization layers, when testing their vulcanization layers, it is currently necessary to use multiple ultrasonic probes for testing according to the height of the rubber seismic isolation bearing and the number of vulcanization layers. However, in the actual testing process, the use of multiple probes increases the complexity of the device and is more prone to failure, which greatly affects the detection efficiency.

[0033] S1. placing the rubber seismic isolation bearing to be tested in the bearing groove and positioning it by the clamping member;

[0034] S2. According to the gap between each vulcanized layer of the rubber seismic isolation bearing to be tested, the height of the mounting frame is adjusted by the adjusting member, and the length of the limiting rod is adjusted so that after the limiting frame contacts the limiting rod each time the turntable rotates one circle, the angle of the disk rotation is adjusted to indirectly drive the ultrasonic detection assembly to descend to the position of the next vulcanized layer;

[0035] S3. When the detection starts, the drive motor drives the turntable to rotate.

As the turntable continues to rotate, the coupling agent is sprayed on the outer wall of the next vulcanized layer to be tested, so that there is no need to spray a large area in advance, resulting in a waste of coupling agent, and it is avoided that the time interval between spraying in advance and the detection is too long, resulting in inaccurate detection;

[0037] S5. While the turntable rotates, the air guide assembly is driven to guide air into the air injection pipe. After the air is ejected through the air injection pipe, the air is sprayed to the side wall of the rubber seismic isolation support below the nozzle, thereby preventing impurities from adhering to the side wall of the rubber seismic isolation support and affecting the detection result.

[0038] Compared with the prior art, the beneficial effect of the present invention is that, when the ultrasonic detection device and method of rubber seismic isolation bearings are driven by the driving motor to drive the turntable to rotate for detection, when the turntable rotates one circle, the ultrasonic detection mechanism is automatically driven to descend once, and descends to the next vulcanization layer to be tested, so that with the continuous rotation of the turntable, the ultrasonic detection mechanism gradually moves downward intermittently, and completes the layer-by-layer detection of the vulcanization layer through an ultrasonic detection component. At the same time, the ultrasonic detection component descends once, and drives the coupling agent spraying mechanism to work once, and sprays the coupling agent on the outside of the vulcanization layer to be tested, thereby reducing the waste caused by large-scale premature spraying, replacing the traditional method of ultrasonic detection of rubber seismic isolation bearings, avoiding the need to use multiple probes when performing ultrasonic detection on rubber seismic isolation bearings, thereby making the device highly complex and having a high failure rate, affecting the detection efficiency.

[0053] Figure 1-Figure 8 Shown is a structural schematic diagram of a rubber isolation bearing ultrasonic detection device and method of the present invention. Please refer to Figure 1-Figure 8 for a detailed introduction to such a rubber isolation bearing ultrasonic detection device and method.

[0054] Embodiment 1

[0055] Refer to Figure 1-Figure 7 , the present invention discloses a rubber isolation bearing ultrasonic detection device, the main part of which includes a loading mechanism 100, an ultrasonic detection mechanism 200, and a coupling agent spraying mechanism 300.

[0056] Refer to Figure 1-Figure 3 , the loading mechanism 100 is used to load the rubber isolation bearing to be detected and drive it to rotate during the detection process. The loading mechanism 100 includes a base 110 with a driving motor inside and a loading member 120 whose bottom is connected to the output end of the driving motor and is used to load the rubber isolation bearing. The base 110 is used to support the entire device, the driving motor is used to drive the loading member 120 to rotate during operation, and the loading member 120 is used to load and fix the rubber isolation bearing;

[0057] Refer to Figure 1-Figure 7The ultrasonic detection mechanism 200 is used to perform ultrasonic detection on the vulcanization layer of the rubber seismic isolation support on the bearing member 120 when working. The ultrasonic detection mechanism 200 is installed on one side of the base 110 and performs ultrasonic detection on the vulcanization layer of the rubber seismic isolation support when working, wherein, when the driving motor drives the bearing member 120 to rotate one circle, the ultrasonic detection mechanism 200 is automatically driven to move downward to a position corresponding to the next vulcanization layer, so that in the process of driving the motor to drive the bearing member 120 to rotate, each time the bearing member 120 rotates one circle, the ultrasonic detection mechanism 200 is automatically driven to move downward once and move to a position corresponding to the next vulcanization layer, thereby facilitating ultrasonic detection of the next vulcanization layer;

[0058] refer to Figure 1-Figure 7 The coupling agent spraying mechanism 300 is used to spray the coupling agent onto the side wall of the rubber seismic isolation bearing when working. The coupling agent spraying mechanism 300 is installed on the ultrasonic detection mechanism 200. When the ultrasonic detection mechanism 200 moves downward once, the coupling agent spraying mechanism 300 is automatically driven to work once, and the coupling agent solution is sprayed onto the next vulcanized layer to be tested. Therefore, each time the ultrasonic detection mechanism 200 moves downward once, the coupling agent spraying mechanism 300 is automatically driven to work once, and the coupling agent is sprayed onto the outer wall of the vulcanized layer to be tested.

[0059] In this embodiment, reference Figure 3 The bearing member 120 includes a turntable 120a whose bottom is connected to the output end of the driving motor and has a bearing groove 120a-1 on the top, and a plurality of clamping members 120b located on the top of the turntable 120a and fixing the side wall of the rubber isolation support during operation. The turntable 120a is used to drive the rubber isolation support to rotate when rotating, the bearing groove 120a-1 is used to carry and position the rubber isolation support, and the plurality of clamping members 120b are used to clamp and fix the rubber isolation support in the bearing groove 120a-1, so that the position is more accurate during detection;

[0060] In this embodiment, the present invention further discloses an ultrasonic detection method for rubber seismic isolation bearings, which includes the above-mentioned ultrasonic detection device for rubber seismic isolation bearings.

[0061] In this embodiment, the specific usage process is as follows: the rubber seismic isolation bearing to be tested is placed in the bearing groove 120a-1, and it is clamped and positioned by the clamping member 120b. At the beginning of the test, the top vulcanization layer of the rubber seismic isolation bearing located in the bearing groove 120a-1 is tested by the ultrasonic testing mechanism 200, and as the driving motor drives the turntable 120a to rotate continuously, the ultrasonic testing mechanism 200 performs a comprehensive test on the vulcanization layer. Each time the turntable 120a rotates one circle, the ultrasonic testing mechanism 200 is driven to move downward once and move to a position corresponding to the next vulcanization layer. With the continuous rotation of the turntable 120a, it is convenient to perform ultrasonic testing on the next vulcanization layer, so that layer by layer testing is performed by an ultrasonic testing mechanism 200, thereby reducing the testing cost. When the ultrasonic testing mechanism 200 moves downward once, it automatically drives the coupling agent spraying mechanism 300 to work once, and sprays the coupling agent on the outer wall of the vulcanization layer to be tested, thereby avoiding waste caused by large-scale spraying in advance.

When the first threaded rod 230a rotates The ultrasonic detection component 220 is driven to descend along the first limiting slide groove 210a to the position corresponding to the next vulcanization layer. When the limiting frame 120a-2 is separated from the limiting rod 230b-32, the torsion spring is reset to drive the bevel gear set 230b-1 to reverse. When the bevel gear set 230b-1 reverses, it drives the connecting rod 230b-2 and the disc 230b-3 to reverse, and drives the limiting rod 230b-32 to return to its original position, so that as the turntable 120a continues to rotate, the ultrasonic detection component 220 is driven to perform ultrasonic detection on the vulcanization layer layer by layer.

[0073] Example 3

[0074] Based on Example 2, Figure 1-Figure 7 The coupling agent spraying mechanism 300 includes a spraying assembly 310 installed at the bottom of the mounting plate 220a, a coupling agent containing box 320 located at the top of the fixing plate 210b and having two first connection ports 320a at the top, and an air bag 330 located at the top of the coupling agent containing box 320 and having a bottom connected to one of the first connection ports 320a and a top corresponding to the mounting plate 220a. The spraying assembly 310 is used to spray the coupling agent solution during operation. The coupling agent containing box 320 is used to store the coupling agent solution. One of the first connection ports 320a is used to introduce the air squeezed out of the air bag 330 into the coupling agent containing box 320 after the air bag 330 is squeezed. The other first connection port 320a is used to discharge the coupling agent squeezed out by the high-pressure air through the coupling agent containing box 320 after the high-pressure air enters the coupling agent containing box 320. The air bag 330 is used to force the coupling agent containing box 320 to squeeze out a part of the coupling agent solution from the other first connection port when the mounting plate 220a is lowered and squeezed.

[0075] The spray assembly 310 includes a liquid guide tube 310a installed at the bottom of the mounting plate 220a and having a second connection port 310a-1 on the side wall, and a nozzle 310b connected to the liquid guide tube 310a and located below the ultrasonic probe 220b. The liquid guide tube 310a is used to introduce the coupling agent solution discharged through the coupling agent holding box 320 into the nozzle 310b, and the nozzle 310b is used to spray the coupling agent solution introduced through the liquid guide tube 310a. The second connection port 310a-1 is connected to another first connection port 320a through a hose, and is used to introduce the coupling agent solution discharged through the first connection port 320a into the liquid guide tube 310a.

[0076] In this embodiment, the specific working process is as follows: when the mounting plate 220a descends once, the top of the airbag 330 is moved once, so that the squeezed air in the airbag 330 enters the coupling agent holding box 320 through one of the connecting ports, so that the high-pressure air inside the coupling agent holding box 320 squeezes out a part of the coupling agent solution from the other first connecting port 320a, and then is introduced into the liquid guide tube 310a through a hose, and then the coupling agent solution is sprayed to the outer wall of the next vulcanized layer to be tested through the nozzle 310b. As the turntable 120a continues to rotate, the coupling agent solution is evenly sprayed on the outer wall of the vulcanized layer of the rubber seismic isolation bearing.

[0078] Based on Example 3, Figure 4-Figure 7 The side wall of the mounting frame 210 has a limiting slide bar 210c and a second limiting slide groove 210d. The limiting slide bar 210c is used to limit the movable frame 240b, so that when the second threaded rod 230b-12 rotates, the movable frame 240b moves linearly along the second threaded rod 230b-12 and the limiting slide bar 210c. The second limiting slide groove 210d is used to make the movable plate 240a-1 move along the second limiting slide groove 210d when moving;

[0079] The side wall of the mounting plate 220a has a limit block 220a-1, which is used to cooperate with the elastic protrusion 240a-2, so that when the turntable 120a is rotating and the limit frame 120a-2 is not in contact with the limit rod 230b-32, the entire ultrasonic detection mechanism 200 is limited and fixed, thereby avoiding that the first threaded rod 230a cannot position the ultrasonic detection mechanism 200 under its own gravity, causing the turntable 120a to be unable to rotate a complete circle, the ultrasonic detection mechanism 200 is unstable, and the side wall detection of the vulcanized layer of some rubber seismic isolation bearings is missing;

[0080] A second threaded rod 230b-12 is connected between the bevel gear set 230b-1 and the connecting rod 230b-2. When rotating, under the cooperation of the limit slide rod 210c, the movable frame 240b moves along the second threaded rod 230b-12 and the limit slide rod 210c, so that the movable frame 240b squeezes the side wall of the movable plate 240a-1, and then releases the limit of the limit convex block on the limit block 220a-1;

[0081] Reference Figure 4-Figure 7 , the ultrasonic detection mechanism 200 further includes a limit component 240 for limiting the ultrasonic detection mechanism 200 when it does not move downward. When the turntable 120a rotates and the limit frame 120a-2 does not contact the limit rod 230b-32, the limit component 240 stabilizes the installation plate 220a. The limit component 240 includes a limit member 240a movably installed on one side of the installation plate 220a and a movable frame 240b with one end slidably sleeved on the limit slide rod 210c and the other end threadedly sleeved on the second threaded rod 230b-12. The limit member 240a is used to limit the installation plate 220a. When the limit frame 120a-2 contacts the limit rod 230b-32 and the connecting rod 230b-2 rotates to drive the second threaded rod 230b-12 to rotate, the movable frame 240b is driven by the driving force of the second threaded rod 230b-12 to squeeze the limit member 240a, and then the limit member 240a releases the limit on the installation plate 220a;

[0082] The limit member 240a includes a movable plate 240a-1 with upper and lower ends extending into the second limit chute 210d, a plurality of elastic convex blocks 240a-2 located on the side wall of the movable plate 240a-1 and corresponding to the limit blocks 220a-1, and a plurality of elastic members 240a-3 located on the side wall of the movable plate 240a-1 and the other end connected to the side wall of the installation plate 220a. The movable plate 240a-1 is used to facilitate the installation of a plurality of elastic convex blocks 240a-2. The elastic convex blocks 240a-2 are used to limit the limit blocks 220a-1, and the elastic convex blocks 240a-2 can deform after contacting the side wall of the limit blocks 220a-1 without affecting the continuous movement of the movable plate 240a-1, so as not to affect the extension of the lower elastic convex blocks 240a-2 to limit the bottom of the limit blocks 220a-1.

[0083] In this embodiment, the specific working process is as follows: when the limit frame 120a-2 is in contact with the limit rod 230b-32, the elastic protrusion 240a-2 limits the limit block 220a-1, thereby maintaining the stability of the mounting plate 220a. When the limit frame 120a-2 is squeezed and contacted with the limit rod 230b-32, as the second threaded rod 230b-12 rotates, the movable frame 240b is driven to move along the second threaded rod 230b-12 and the limit sliding rod 210c, and the side wall of the movable plate 240a-1 is squeezed, thereby The elastic protrusion 240a-2 releases the limit on the limit block 220a-1, which facilitates the downward movement of the installation plate 220a. At this time, the elastic component 240a-3 is squeezed. When the limit frame 120a-2 is separated from the limit rod 230b-32, the elastic component 240a-3 is reset, so that the movable plate moves to its original position in the second limit slide groove 210d. The elastic protrusion 240a-2 limits the limit block 220a-1 again. At this time, the movable frame 240b moves back to its original position, which is convenient for the next squeezing of the movable plate 240a-1.

[0084] Example 5

[0085] On the basis of Example 4, in order to prevent the side wall of the rubber isolation support from being attached with impurities and affecting the ultrasonic testing results, reference Figure 2-Figure 6 , further comprising a cleaning mechanism 400, which is used to blow off impurities attached to the outer wall of the rubber seismic isolation support during the rotation of the turntable 120a, the cleaning mechanism 400 comprises an air jet pipe 410 located at the bottom of the mounting plate 220a and below the nozzle 310b, and an air guide component 420 which is transmission-connected to the air jet pipe 410 at one end and transmission-connected to the turntable 120a at the other end, the air jet pipe 410 is used to eject a high-pressure airflow to blow off impurities attached to the side wall of the rubber seismic isolation support, the air guide component 420 is used to introduce flowing air into the air jet pipe 410 when the turntable 120a rotates, and the side wall of the air jet pipe 410 has a third connecting port 410a, which is used to introduce flowing air delivered through the second connecting port 310a-1 into the air jet pipe 410;

[0086] The air guide component 420 includes a fixing frame 420a installed at one side of the base 110 and having a fourth connection port 420a-1 at the bottom, and a fan 420b installed in the fixing frame 420a and having a first belt pulley 420b-1 on the top rotating shaft. The fixing frame 420a is used to facilitate the installation of the fan 420b. The fourth connection port 420a-1 is used to guide the airflow generated when the fan 420b rotates to the third connection port 410a. The fan 420b is used to generate a fast-flowing airflow when rotating. The first belt pulley 420b-1 is used to drive the fan 420b to rotate when rotating. The fourth connection port 420a-1 is connected to the third connection port 410a through a hose.

[0087] The top of the base 110 is provided with a transmission gear 110a having a second belt pulley 110a-1 at the bottom. The transmission gear 110a is used to drive the second belt pulley 110a-1 to rotate when it rotates. The second belt pulley 110a-1 is connected to the first belt pulley 420b-1 through a belt, and is used to drive the first belt pulley 420b-1 to rotate when the second belt pulley 110a-1 rotates.

[0088] The outer wall of the rotating disk 120a is evenly provided with a plurality of saw teeth 120a-3 meshing with the transmission gear 110a along the circumferential direction, so as to drive the transmission gear 110a to rotate under the meshing connection of the saw teeth 120a-3 when the rotating disk 120a rotates.

[0089] In this embodiment, the specific working process is as follows: when the turntable 120a rotates, the transmission gear 110a is driven to rotate through the sawtooth 120a-3, and when the transmission gear 110a rotates, it drives the second pulley 110a-1 to rotate, and when the second pulley 110a-1 rotates, it drives the first pulley 420b-1 and the fan 420b to rotate. When the fan 420b rotates, the fast-flowing airflow generated by the rotation of the fan 420b enters the third connecting port 410a through the fourth connecting port 420a-1, and is then ejected by the jet pipe 410. As the turntable 120a continues to rotate, the jet pipe 410 continuously sprays the side wall of the rubber seismic isolation support under the nozzle 310b, thereby blowing away impurities attached to its outer wall.

[0090] A rubber seismic isolation bearing ultrasonic detection method, which includes the above rubber seismic isolation bearing ultrasonic detection device, and the specific steps are as follows:

[0091] S1, placing the rubber seismic isolation support to be tested in the bearing groove 120a-1, and positioning it by the clamping member 120b;

[0092] S2. According to the gap between each vulcanized layer of the rubber seismic isolation bearing to be tested, the height of the mounting frame 210 is adjusted by the adjusting member 110b, and the length of the limiting rod 230b-32 is adjusted so that after the limiting frame 120a-2 contacts the limiting rod 230b-32 every time the turntable 120a rotates one circle, the angle of the rotation of the disk 230b-3 is sufficient to indirectly drive the ultrasonic detection assembly 220 to descend to the position of the next vulcanized layer;

[0093] S3, when the detection starts, the rotating disk 120a is driven to rotate by the driving motor. After the rotating disk 120a rotates one circle, when the limit frame 120a-2 contacts the limit rod 230b-32, the driving disk 230b-3 rotates once, thereby driving the ultrasonic detection component 220 to descend once through the transmission component 230, and descend to the position of the next vulcanization layer, so that the ultrasonic probe 220b can perform ultrasonic detection on the next vulcanization layer, thereby detecting multiple vulcanization layers through one ultrasonic probe 220b;

[0094] S4. After the mounting plate 220a of the ultrasonic detection assembly 220 is lowered once, the airbag 330 below is squeezed once, and the air squeezed out of the airbag 330 enters the coupling agent holding box 320, thereby squeezing a portion of the coupling agent solution in the coupling agent holding box 320 to the nozzle 310b, and the coupling agent is continuously sprayed out through the nozzle 310b. As the subsequent turntable 120a continues to rotate, the coupling agent is sprayed on the outer wall of the next vulcanized layer to be tested, so that there is no need to spray a large area in advance, resulting in a waste of coupling agent, and it is avoided that the time interval between the lamp and the test is too long after the spraying in advance, resulting in inaccurate detection;

[0095] S5. While the turntable 120a rotates, the air guide assembly 420 is driven to guide air into the air injection pipe 410. After the air is ejected through the air injection pipe 410, it is sprayed to the side wall of the rubber isolation support below the nozzle 310b, thereby preventing impurities attached to the side wall of the rubber isolation support from affecting the detection result.
