Description

Technical Field

[0001] The present invention relates to the technical field of floating plate vibration isolator detection, and in particular to a floating plate vibration isolator mechanical performance detection and adjustment device. Background Art

[0002] Subway floating slab vibration reduction technology, with its unique structural design and material properties, has become a key engineering vehicle for solving rail transit vibration pollution. This technology uses a mass-spring system consisting of a slab and steel spring isolators to tune and absorb vibration energy in different frequency bands generated by train operation, achieving a broadband and efficient vibration isolation effect. In particular, its ability to control low-frequency vibrations is significantly better than traditional vibration reduction solutions. However, the isolators are installed inside the trackbed, and the stress conditions of the isolators cannot be accurately detected during the construction and maintenance periods, making it difficult to effectively control and analyze whether the stress on the floating slab is normal. Therefore, when the isolators have installation deviations, aging of the steel springs, or load force deviations, it is difficult for maintenance personnel to promptly detect the unbalanced stress on the floating slab and the isolators on it, resulting in incompleteness and uncertainty in the maintenance process. If the isolators are not maintained in a timely manner, dangerous situations such as air gaps between the floating slab and the foundation layer and brittle fracture caused by stress concentration on the isolators may easily occur.

[0003] In recent years, some regions have begun experimenting with the application of emerging digital detection systems (which use sensors to detect the probe's retraction distance and retraction frequency in real time, more easily tracking and recording changes in the distance between the floating plate and the ground) to replace the cumbersome manual detection process. However, because the floating plate is typically supported upward and resisted horizontal movement only by the steel springs on the isolators (i.e., existing isolators typically do not include longitudinal limit structures to reduce the probability of wear and jamming of the floating plate during train operation), when using digital detection systems, the sensor probe can usually only be set to abut the detected surface (the floating plate or the isolator top plate) to prevent the sensor probe from being bent by lateral compression from the detected surface. However, this inevitably results in the sensor probe being separated from the detected surface due to the instantaneous downward force as it vibrates up and down with the detected surface. This causes the sensor to detect that the probe's downward movement is greater than the actual downward movement of the floating plate, resulting in increased actual detection errors. Therefore, it can be seen that there is still room for optimization in the structure of existing digital detection systems. Summary of the Invention

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1: The present invention proposes a floating plate isolator mechanical property detection device. Compared with the existing digital detection device, this device overcomes the horizontal shaking of the detected plane while following the up and down movement of the detected plane, thereby reducing the probability of the detection probe being bent and damaged. At the same time, compared with the existing digital detection device, the detection accuracy of this device is enhanced.

[0030] Reference Figure 1-Figure 5 , including an outer sleeve 1, a spring isolator is installed between the outer sleeve 1 and the ground, the spring isolator is an existing device, refer to Figure 2 and Figure 3, consists of a spring seat 2, a spring top plate 3 and a steel spring 4. The spring seat 2 is fixed to the ground, the spring top plate 3 is slidably connected to the outer sleeve 1, and an adjustment module is provided between the spring top plate 3 and the outer sleeve 1. The adjustment module is an existing device for adjusting the initial load force of the spring isolator. The spring seat 2 and the spring top plate 3 are not in direct contact. The steel spring 4 is fixed between the spring seat 2 and the spring top plate 3. A fixed column 5 is fixed in the spring seat 2. The upper part of the fixed column 5 is slidably connected to the detection rod 6. A fixed end 7 is fixed in the spring top plate 3. The fixed end 7 is fixed with a circumferentially evenly distributed arc spring plate 8. The lower end of the arc spring plate 8 is fixed to the detection rod 6. A first sensor 9 is fixed in the fixed column 5 (the first sensor 9 is an existing Device, the first sensor 9 is electrically connected to an electronic chip integrated with data recording and data conversion functions. The electronic chip can be fixed at any position and has its own small power supply device. For example, the electronic chip is fixed to the bottom outside the spring seat 2. The electronic chip is connected to the staff's mobile control terminal through Bluetooth / Zigbee and other transmission methods. The staff obtains the data stored in the electronic chips in each different device through the mobile control terminal). A first detection spring 10 is installed between the first sensor 9 and the detection rod 6. The first sensor 9 is used to detect the elastic force of the first detection spring 10. The electronic chip then converts the detected elastic force into a spring compression distance, and then detects the displacement distance of the floating plate and the spring isolator.

[0031] The above setting can be achieved. When the floating plate drives the spring top plate 3 to shift horizontally during vibration, the circumferentially distributed arc spring plate 8 allows the fixed end 7 and the detection rod 6 to be misaligned through deformation. At the same time, the elastic force of the circumferentially distributed arc spring plate 8 drives the detection rod 6 to move up and down following the fixed end 7. The first sensor 9 and the electronic chip detect the distance the detection rod 6 moves downward through the first detection spring 10, and record the distance the floating plate moves up and down when vibrating.

[0032] Reference Figure 5-Figure 7 A first magnet 11 is fixed to the lower side of the fixed end 7, a connecting piece 12 is provided on the upper part of the detection rod 6, and a second magnet 121 is fixed to the top of the connecting piece 12. The first magnet 11 and the second magnet 121 magnetically repel each other (that is, assuming that the N pole of the first magnet 11 is facing downward, the N pole of the second magnet 121 is facing upward).

[0033] Reference Figure 6 and Figure 7 The surface area of ​​the lower side of the first magnet 11 is larger than the surface area of ​​the upper side of the second magnet 121, which is used to ensure that when the first magnet 11 deviates horizontally following the fixed end 7, the first magnet 11 can still effectively apply a downward magnetic force to the second magnet 121.

[0034] The above arrangement can achieve that, when the fixed end 7 undergoes a large horizontal deflection, causing multiple arc spring plates 8 to be stretched horizontally, the arc spring plates 8 cannot apply stable downward pressure, but when the fixed end 7 moves downward in a horizontally offset state, the first magnet 11 pushes the second magnet 121 and the connecting member 12 to move downward together through magnetic force, thereby increasing the detection accuracy of the device when the arc spring plates 8 are difficult to work normally.

[0035] The above setup works like this:

[0036] The staff installed the device at the corresponding position on the floating plate, and adjusted all the spring isolators on the same floating plate to the appropriate state by adjusting the adjustment modules of each spring isolator, ensuring that the floating plate is in a force balance state when it is static.

[0037] After the staff has installed the floating plates of the entire railway, during the operation of the train, the floating plates vibrate irregularly due to the force transmitted by the train. The steel springs 4 in all spring isolators are deformed and cushion the vibrations of the floating plates, reducing the noise generated by the vibrations. During this process, taking one group of spring isolators as an example, the fixed end 7, the spring top plate 3 and the outer sleeve 1 vibrate together with the floating plates, while the fixed column 5 and the spring seat 2 remain relatively stationary.

[0038] When the fixed end 7 undergoes horizontal relative displacement relative to the fixed column 5, if the displacement amplitude does not exceed the elastic range of the arc spring plate 8, all the arc spring plates 8 will follow the fixed end 7 to swing in the horizontal direction, while driving the lower side detection rod 6 to move downward or upward through compression and tension. When the detection rod 6 moves in the vertical direction, the elastic force of the first detection spring 10 changes, and the first sensor 9 detects the change in the elastic force of the first detection spring 10 and transmits the data to the adjacent electronic chip. The electronic chip converts the change in the elastic force of the first detection spring 10 into the distance that the detection rod 6 moves downward or upward, and then detects and records the distance that the floating plate moves up and down when it vibrates.

[0039] When the train is out of service, the staff uses a handheld mobile control terminal to collect the detection data of the floating plate, connects to the electronic chips on all the floating plates in sequence through Bluetooth / Zigbee and other transmission methods, and extracts the detection data records in all electronic chips. The staff then analyzes the collected detection data to determine the performance and status of the spring isolators on different floating plates, and promptly inspects and replaces the spring isolators with abnormal data.

[0040] In the first embodiment, the detection rod 6 and the connecting member 12 are considered to be fixedly connected, while in this embodiment, the detection rod 6 and the connecting member 12 are slidably connected.

[0041] Example 2: Based on the floating plate isolator mechanical performance detection device proposed in Example 1, more comprehensive and detailed detection means are added. By adding the detection of the distance between the first magnet 11 and the second magnet 121, the detection data of this device is made more accurate and reliable.

[0042] Reference Figure 6 and Figure 7 A second sensor 13 is fixedly connected to the detection rod 6 (the second sensor 13 is an existing device, and the second sensor 13 is electrically connected to the electronic chip in Example 1). A second detection spring 14 is installed between the second sensor 13 and the connecting member 12. The elastic force of the second detection spring 14 is less than the sum of the elastic forces of the arc spring plate 8 uniformly distributed in the circumferential direction. A third magnet 15 is fixedly connected to the detection rod 6. The second magnet 121 and the third magnet 15 magnetically repel each other (that is, assuming that the S pole of the second magnet 121 is downward, the S pole of the third magnet 15 is upward). When the floating plate is in a stationary state, the magnetic force exerted by the third magnet 15 on the second magnet 121 is equal to the sum of the magnetic force exerted by the first magnet 11 on the second magnet 121 and the gravity of the connecting member 12 and the second magnet 121.

[0043] The above arrangement can be achieved, when the fixed end head 7 is relatively displaced in the horizontal direction relative to the fixed column 5, and the fixed end head 7 moves downward due to vibration, the first magnet 11 moves downward relative to the second magnet 121, and the distance between the first magnet 11 and the second magnet 121 is reduced. At this time, the magnetic repulsion between the first magnet 11 and the second magnet 121 is greater than the magnetic repulsion between the third magnet 15 and the second magnet 121. The second magnet 121 is pushed downward by the first magnet 11, and the second magnet 121 and the connecting member 12 jointly press the second detection spring 14 downward. The second detection spring 14 is compressed and stores force. At this time, the second sensor 13 detects the elastic force of the second detection spring 14 and transmits the data to the electronic chip. The electronic chip converts the change in the elastic force of the second detection spring 14 into the distance that the connecting part 12 moves downward or upward, and then detects and records the distance that the connecting part 12 moves up and down. The value of the change in the distance between the fixed end 7 and the detection rod 6 is thus known. The electronic chip combines the received distance between the fixed end 7 and the detection rod 6 and the distance the detection rod 6 moves to more accurately detect the distance that the floating plate moves up and down when it vibrates.

[0044] Reference Figure 7The lower side of the connecting member 12 and the detection rod 6 are non-sealed connections, and the gap between the lower side of the connecting member 12 and the detection rod 6 is small. Therefore, during the downward movement of the connecting member 12, it is difficult for the air on its lower side to flow upward through the gap between the lower side of the connecting member 12 and the detection rod 6, resulting in damping of the detection rod 6 during vertical movement, thereby reducing the amplitude of the connecting member 12 following the fixed end 7 in the vibration process, thereby reducing the detection error of the second sensor 13.

[0045] Reference Figure 4 and Figure 5 A flexible magnetic shielding cover 151 (made of existing synthetic materials, such as a flexible silicone material containing ferrite powder) is fixed to the lower side of the fixed end 7, and the first magnet 11, the second magnet 121 and the third magnet 15 are all located in the flexible magnetic shielding cover 151.

[0046] The above-mentioned setting can be achieved by increasing the movement resistance of the connecting part 12, improving the stability of the connecting part 12 during movement, reducing the intensity of the up and down reciprocating fluctuations of the connecting part 12, and thereby increasing the accuracy and stability of the detection data of the second sensor 13. At the same time, the flexible magnetic shielding cover 151 is used to reduce the influence of external vibrations or electromagnetic components on the train on the first magnet 11, the second magnet 121 and the third magnet 15.

[0047] Example 3: Based on the floating plate isolator mechanical performance detection device proposed in Example 1, the detection rod 6 can move upward more stably along with the fixed end 7, reducing the possibility that the detection rod 6 will be difficult to quickly move upward and reset along with the fixed end 7 after being subjected to a sudden downward vibration force.

[0048] Reference Figure 7 and Figure 8 , three fixed cylinders 16 are fixedly connected to the outer side of the detection rod 6 and are evenly distributed in the circumference. The fixed cylinder 16 is a circular hollow cylinder with closed upper and lower ends. A sliding plate 161 is connected to the fixed cylinder 16 for limited sliding. A pull rope 17 is fixed to the upper side of the sliding plate 161 (the pull rope 17 is a flexible metal rope, such as a steel wire rope). The pull rope 17 penetrates the fixed cylinder 16 and is fixed to the fixed end 7. A tension spring 18 is installed between the sliding plate 161 and the fixed cylinder 16. The elastic coefficient of the tension spring 18 is less than the elastic coefficient of the arc spring plate 8. The tension spring 18 is in a stretched and stored state when the spring isolator is in a static state (that is, the state shown in the figure).

[0049] Reference Figure 8 and Figure 9Four circumferentially evenly distributed fixed plates 19 are fixed inside the sliding plate 161. A gap is left between two adjacent fixed plates 19 on the same sliding plate 161. When the sliding plate 161 drives the fixed plate 19 to slide up and down relative to the fixed cylinder 16, the gas on the upper and lower sides of the cavity where the sliding plate 161 is located flows up and down through the gap between the two adjacent fixed plates 19. The sliding plate 161 has flexible sheets 20 evenly distributed circumferentially fixed thereto. The flexible sheets 20 are used to cover the gap between the two adjacent fixed plates 19, thereby changing the space for gas flow.

[0050] The above arrangement can be achieved, when the fixed end head 7 pushes the detection rod 6 to move downward through the arc spring plate 8 and the first magnet 11, the distance between the fixed end head 7 and the detection rod 6 and the fixed cylinder 16 is reduced, the pull rope 17 is relaxed, and the sliding plate 161 moves downward under the drive of the tension spring 18, and the gas on the lower side of the sliding plate 161 in the fixed cylinder 16 flows to the upper side of the sliding plate 161 in the fixed cylinder 16. At this time, the gas can blow the flexible sheet 20 upward to deform the flexible sheet 20, and the flexible sheet 20 no longer covers the gap between the two adjacent fixed plates 19, thereby flowing upward in a low resistance state. When the distance between the fixed end head 7 and the detection rod 6 increases, the pull rope 17 is relaxed, and the sliding plate 161 moves downward under the drive of the tension spring 18. 17 is dragged upward by the fixed end 7, so that when the sliding plate 161 moves upward, the tension spring 18 is stretched and stored, and the gas on the upper side of the sliding plate 161 flows to its lower side. At this time, the flexible sheet 20 is affected by the airflow and is close to the gap between the two adjacent fixed plates 19, hindering the flow of gas, thereby increasing the movement resistance of the sliding plate 161. The sliding plate 161 slows down the downward movement speed of the fixed cylinder 16 and the detection rod 6 through this resistance, making it easier for the arc-shaped spring plate 8 to pull the detection rod 6 upward faster. When the sliding plate 161 returns to the position of the static state shown in the figure, the pull rope 17 directly drives the fixed cylinder 16 and the detection rod 6 to move upward by dragging the sliding plate 161.

[0051] Example 4: A floating plate isolator adjustment device is proposed to replace the adjustment module described in Example 1 and solve the problems existing in the existing adjustment module: the existing adjustment module is usually composed of different numbers of leveling steel plates arranged on the upper layer of the isolator. By increasing or decreasing the thickness of the leveling steel plates on the upper layer of the isolator, the static force of the spring isolator, the elevation of the floating plate and the force balance in the static state are adjusted (for example, the force of one of the spring isolators is increased to adjust the horizontality of the floating plate). However, because each spring isolator needs to be adjusted separately, and the adjustment is usually performed in a step-by-step manner by increasing or decreasing the number of leveling steel plates, the adjustment method is cumbersome and it is difficult to make fine adjustments to the force of each spring isolator and the elevation of the floating plate.

[0052] refer to Figure 2-Figure 4, including a mounting plate 21, the mounting plate 21 is fixedly connected to the outer sleeve 1, and a fixed gasket 22 is fixedly connected to the lower side of the mounting plate 21, and a hydraulic push rod 23 is fixedly connected to the fixed gasket 22, and the telescopic end of the hydraulic push rod 23 is fixedly connected to the spring top plate 3. The hydraulic push rod 23 realizes continuous and stepless adjustment of the load force of a single spring isolator and the elevation of the floating plate by increasing or decreasing the hydraulic oil therein. A pressure transmitter and transmission module 24 is fixedly connected to the hydraulic push rod 23, and an oiling nozzle 25 is provided on the hydraulic push rod 23. The pressure transmitter and transmission module 24 is provided with existing components such as batteries, oil pressure signal acquisition, processing and transmission components. The pressure transmitter and transmission module 24 can be used to replace the electronic chip in Example 1, or two different electronic chips can be used separately.

[0053] Reference Figure 3 and Figure 4 A one-way valve is provided in the oiling nozzle 25. The oiling nozzle 25 can be connected to the external hydraulic system or to the high-pressure airbag. The high-pressure airbag contains high-pressure gas and a certain amount of hydraulic oil. In this embodiment, a scheme of installing the high-pressure airbag on the oiling nozzle 25 after adjusting the height of the hydraulic push rod 23 through the oiling nozzle 25 is described. The spring top plate 3 is fixed with circumferentially evenly distributed limiting screws 301. The limiting screws 301 penetrate the mounting plate 21 and the fixing gasket 22. The limiting screws 301 are threadedly connected to the limiting bolts 302. The limiting bolts 302 are used to limit the height of the mounting plate 21.

[0054] The above arrangement can be achieved by injecting hydraulic oil into the hydraulic push rod 23 through the oiling nozzle 25 to control the distance between the spring isolator and the mounting plate 21, thereby adjusting the load force of the spring isolator in a static state and adjusting the elevation of the floating plate. When the adjustment is completed, the high-pressure airbag with high-pressure gas and a fixed amount of hydraulic oil is connected to the oiling nozzle 25. Because a one-way valve is installed in the oiling nozzle 25, the hydraulic oil in the hydraulic push rod 23 cannot flow into the high-pressure airbag. When the ground near the floating plate sinks or the spring isolator sinks due to gas reasons, causing the static load force of the spring isolator to become smaller, the high-pressure airbag injects hydraulic oil into the hydraulic push rod 23 through the high-pressure gas therein, replenishing hydraulic oil into the hydraulic push rod 23, and realizing adaptive adjustment of the static load force of the spring isolator, so that the spring isolator located in the settlement area can still provide effective supporting force.

[0055] While the disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that numerous other embodiments can be devised which do not depart from the scope of the invention.
