Description

TECHNICAL FIELD

[0002] The vibration table is mainly used for building structure seismic test research, and is a modern vibration test system integrating a vibration platform surface, a vibration excitation system, a test system and an analysis system.

[0003] In the working process of the existing vibration table, the vibration excitation connecting rod of the vibration excitation system is often matched with the vibration platform surface to achieve the purpose of simulating vibration. However, in the preparation process before simulating vibration of various buildings, the vibration table often needs to be transported or the position angle of the vibration table needs to be adjusted, and in this process, the vibration excitation connecting rod is easily damaged due to collision with the vibration platform surface, which has poor safety and reduces the service life of the vibration table. The existing vibration locking mechanism can only lock the vibration excitation connecting rod, and cannot monitor the tightness of the vibration excitation connecting rod after locking. If the locking effect is unstable, the vibration excitation connecting rod will not be protected.

[0004] Therefore, the present application provides a vibration locking mechanism and a vibration table. SUMMARY

[0005] The vibration locking mechanism can monitor the locking effect of the vibration excitation connecting rod in real time by setting a monitoring assembly, so as to avoid the phenomenon of collision damage of the vibration excitation connecting rod in the transportation process.

[0006] Another object of the present application is to provide a vibration table having all the beneficial effects of the above vibration locking mechanism.

[0007] The embodiment of the present application is implemented as follows:

[0008] The vibration locking mechanism provided by the embodiment of the present application comprises:

[0010] The locking assembly comprises a locking column, a driving unit and a housing arranged in the internal cavity. The locking column is arranged in the housing by the driving unit, and the locking column and the housing are matched to form a vibration cavity for accommodating the vibration excitation connecting rod.

[0011] The monitoring assembly comprises a sensor, a processor and a controller, the sensor is arranged in the shell and is used for detecting a pressure signal of the shell and transmitting the pressure signal to the processor, and the processor is used for receiving the pressure signal and sending a control instruction to the controller.

[0013] In some embodiments of the present application, the locking assembly further comprises a locking web, a pad and a spring, two ends of the spring are connected to the bottom of the shell and the pad respectively, the side of the pad away from the spring is connected with the locking web, and the driving unit abuts or separates from the locking web.

[0014] By arranging the spring in the locking assembly, the spring rebound performance is utilized, so that the locking assembly can automatically rebound and open in the non-locking state to form a vibration cavity beneficial to the vibration of the excitation connecting rod.

[0019] In some embodiments of the present application, a plurality of transmission protrusions are arranged side by side on the locking column, and the side of the connecting plate is located between the plurality of transmission protrusions.

[0020] The transmission protrusions are arranged on one hand to drive the locking column to move by the locking connecting plate, and on the other hand, the plurality of transmission protrusions have a containing gap between the side of the connecting plate, so as to avoid the phenomenon of structural jamming, and to ensure the dynamic balance of the locking effect of the locking columns on the left and right sides of the shell.

[0021] In some embodiments of the present application, the driving unit includes a cam and a rotating button connected to the cam, and the cam and the locking connecting plate abut or separate from each other.

[0022] The rotating button is arranged to drive the cam to move, and has the characteristics of simple structure.

[0025] In some embodiments of the present application, the identification block is a "T" shaped block structure, and the bottom end of the identification block has a sharp corner.

[0026] The identification block with a sharp corner at the bottom end can further facilitate the observation of the staff, so as to facilitate the control of the working state of the locking assembly.

[0044] Example

[0045] Figure 1 A cross-sectional view of the vibration locking mechanism 100 provided in an embodiment of the present invention in a locked state; Figure 2 This is a cross-sectional view of the vibration locking mechanism 100 provided by an embodiment of the present invention in a released state.

[0046] like Figure 1 and Figure 2 As shown, this embodiment provides a vibration locking mechanism 100, which includes a locking disk 10, a locking assembly, and a monitoring assembly. The locking disk 10 is a disc structure having an internal cavity 101. The locking assembly includes a locking column 111, a drive unit, and a shell 117 arranged in the internal cavity 101. The locking column 111 is slidably arranged in the shell 117 through the drive unit, and the locking column 111 and the shell 117 cooperate with each other to form a vibration cavity 1171 for accommodating the excitation connecting rod 200. The monitoring assembly includes a sensor, a processor, and a controller. The sensor is arranged in the shell 117, and the sensor is used to detect the pressure signal of the shell 117 and transmit the pressure signal to the processor. The processor is used to receive the pressure signal and issue a control instruction to the controller.

[0047] It is worth noting that the vibration locking mechanism 100 can monitor the locking effect of the excitation link 200 in real time by setting a monitoring component, thereby avoiding the occurrence of collision damage to the excitation link 200 during transportation. In addition, it can also serve to remind the user of the working status of the locking component, thereby avoiding damage to the locking component caused by the vibration table during the vibration simulation process. The structural design is reasonable and practical.

[0048] It is also worth mentioning that the sensor can be a pressure sensor, which can be a pressure sensor in the existing product, and details are not repeated here. The processor can include a central processing unit (CPU), an application specific integrated circuit (ASIC), an application specific instruction processor (ASIP), a graphics processing unit (GPU), a physical processing unit (PPU), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic device (PLD), a controller, a microcontroller unit, a reduced instruction set computer (RISC), a microprocessor, or any combination thereof. In this embodiment, the control instruction issued by the processor can be a locking complete instruction (transmitted to the display device to further remind the staff that the device is in the locked state) or a release instruction (transmitted to the controller to control the vibration table to start working through the controller).

[0049] Please refer again to Figure 1 and Figure 2 The locking assembly further comprises a locking web plate 114, a cushion block 115 and a spring 116, the two ends of the spring 116 are connected to the bottom of the shell 117 and the cushion block 115 respectively, the side of the cushion block 115 away from the spring 116 is connected with the locking web plate 114, and the driving unit and the locking web plate 114 abut or separate from each other.

[0050] It can be understood that by arranging the spring 116 in the locking assembly, the spring 116 can automatically rebound and open to form a vibration cavity 1171 conducive to the vibration of the excitation connecting rod 200 in the non-locked state by using the rebound performance of the spring 116. In addition, the cushion block 115 can play a role in positioning and righting the spring 116, avoiding bending and deviation of the spring 116.

[0051] It can also be understood that the positioning effect of the spring 116 can be further improved by arranging a protrusion inserted into the center of the spring 116 under the cushion block 115 to prevent the spring 116 from deviating or tilting.

[0052] In this embodiment, the locking web plate 114 comprises a web plate middle part 1141 and web plate side parts 1142 located on both sides of the web plate middle part 1141, the driving unit and the web plate middle part 1141 abut or separate from each other, and the number of locking columns 111 is two, and the two locking columns 111 are connected with the two web plate side parts 1142 respectively.

[0053] It can be understood that the driving unit and the web plate middle part 1141 abut or separate from each other, which can dynamically limit the position of the two locking columns 111 on the left and right sides through fine tuning on both sides, thereby improving the limitation of the freedom of the excitation connecting rod 200 after being locked by the two locking columns 111, and further increasing the locking performance to avoid the occurrence of shaking of the excitation connecting rod 200 in the locked state.

[0054] Optionally, the locking column 111 includes a column portion 1111 and a limiting portion 1112 that are integrally formed or fixedly connected. The column portion 1111 and the limiting portion 1112 cooperate with each other to form a locking column 111 with an "L"-shaped cross-section. The two locking columns 111 are mirror-imaged on both sides of the shell 117 and cooperate with the shell 117 to form a vibration cavity 1171.

[0055] Specifically, the one-piece molding process is mainly used in the manufacturing industry, which means that a part can be made in one process without the need for secondary or higher processing. The whole process completes the manufacturing of a part in one step. One-piece molding and non-one-piece molding are two different manufacturing processes. The manufactured product or part is a whole without any connection. Compared with non-one-piece molding, it has higher quality and lasts longer. Here, the column part 1111 and the limit part 1112 are formed by integrated die-casting, which can extend the service life of the structure.

[0056] At the same time, as shown in the figure, the cross-section of the limiting portion 1112 is set to be arc-shaped, which can fit well with the exciting link 200, thereby improving the fixing ability of the exciting link 200.

[0057] like Figures 1-3 As shown, a plurality of transmission protrusions 1113 are arranged side by side on the locking column 111 , and the connecting plate side portion 1142 is located between the plurality of transmission protrusions 1113 .

[0058] It is worth noting that the setting of the transmission protrusion 1113 can, on the one hand, drive the locking column 111 to move through the locking connecting plate 114, and on the other hand, there is an accommodating gap between the multiple transmission protrusions 1113 and the connecting plate side 1142, thereby avoiding the phenomenon of structural jamming and ensuring the dynamic balance of the locking effect achieved by the locking columns 111 on the left and right sides of the shell 117.

[0059] like Figure 1 、 Figure 2 and Figure 4 As shown, the driving unit includes a cam 112 and a rotating button 113 connected to the cam 112 , and the cam 112 and the locking link plate 114 are in contact with or separated from each other.

[0060] It is worth noting that the provision of the rotating button 113 facilitates the movement of the cam 112, and its structure is simple. Furthermore, when the small-diameter end surface of the cam 112 abuts against the locking link 114, the excitation link 200 is locked. Its arcuate surface provides a stepless locking effect, which improves locking performance.

[0061] Optionally, the rotating button 113 comprises a button column 1131, two side wing plates 1132 and a mark block 1133, the button column 1131 is a cylindrical structure concentrically arranged with the cam 112, the two side wing plates 1132 are arranged on both sides of the button column 1131 respectively, and the mark block 1133 is protruded on the outer surface of the button column 1131 away from the cam 112.

[0062] Specifically, the arrangement of the side wing plates 1132 facilitates the rotation of the rotating button 113 by the staff, and the existing damping structure arranged in the button column 1131 avoids the rebound phenomenon of the rotating button 113. In addition, the arrangement of the mark block 1133 facilitates the staff to observe the working state (locked state or loosened state) of the locking assembly.

[0063] In the embodiment, the mark block 1133 is a "T" shaped block structure, and the bottom end of the mark block 1133 has a sharp corner 11331.

[0064] It can be understood that the arrangement of the mark block 1133 with the sharp corner 11331 at the bottom end can further facilitate the observation of the staff, thereby facilitating the control of the working state of the locking assembly.

[0065] In addition, the shell 117 has a first mounting groove 1172 and a second mounting groove 1173, the first mounting groove 1172 and the second mounting groove 1173 are respectively close to the two locking columns 111; the sensor comprises at least two pressure sensors, and the at least two pressure sensors are arranged in the first mounting groove 1172 and the second mounting groove 1173 respectively.

[0066] It can be understood that the arrangement of the at least two pressure sensors in the first mounting groove 1172 and the second mounting groove 1173 respectively can determine whether the locking is in place through the pressure difference and the pressure value on both sides, thereby monitoring the tightness of the vibration exciting connecting rod 200 after locking.

[0067] Further, the vibration locking mechanism 100 has at least the following use methods:

[0068] 1) locking the vibration exciting connecting rod 200 by the locking assembly (the locking process is described above, and will not be described here again);

[0069] 2) collecting the pressure values at the positions of the first mounting groove 1172 and the second mounting groove 1173 in real time, and determining whether the vibration exciting connecting rod 200 abuts on the shell 117 based on the pressure value;

[0070] 3) determining whether the multiple side surfaces of the vibration exciting connecting rod 200 achieve the preset locking effect (i.e. stable locking) based on the pressure difference at the positions of the first mounting groove 1172 and the second mounting groove 1173.

[0071] The application further provides a vibration table comprising the vibration locking mechanism 100, and the vibration table further comprises a vibration table body, and the vibration table body is provided with an excitation connecting rod 200 penetrating the vibration cavity 1171.

[0072] In conclusion, the embodiment of the application provides a vibration locking mechanism 100 and a vibration table. The vibration locking mechanism 100 comprises a locking disc 10, a locking assembly and a monitoring assembly. The locking disc 10 is a disc structure with an internal cavity 101. The locking assembly comprises a locking column 111, a driving unit and a shell 117 arranged in the internal cavity 101. The locking column 111 is slidingly arranged in the shell 117 through the driving unit, and the locking column 111 and the shell 117 cooperatively form a vibration cavity 1171 for accommodating the excitation connecting rod 200. The monitoring assembly comprises a sensor, a processor and a controller. The sensor is arranged in the shell 117, and the sensor is used for detecting a pressure signal of the shell 117 and transmitting the pressure signal to the processor. The processor is used for receiving the pressure signal and issuing a control instruction to the controller. The vibration locking mechanism 100 can realize real-time monitoring of the locking effect of the excitation connecting rod 200 through the monitoring assembly, so as to avoid the phenomenon of collision damage of the excitation connecting rod 200 in the transportation process. In addition, the vibration locking mechanism 100 can also play a role of reminding the user of the working state of the locking assembly, thereby avoiding damage to the locking assembly in the vibration simulation process of the vibration table. The structure design is reasonable and has high practicability.

[0073] The above only describes the preferred embodiments of the application and is not used to limit the application.
