Description

Technical Field

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

[0002] As a benchmark technology for vibration and noise reduction in urban rail transit, steel spring floating slab track has become the preferred solution for subways crossing sensitive areas with its efficient vibration isolation performance (20dB-40dB noise reduction), long life and flexible adaptability. Among them, prefabricated floating slabs have the advantages of high construction efficiency, stable and controllable quality, less on-site interference, low cost, strong adaptability, and convenient long-term maintenance. Compared with cast-in-place slabs, their proportion has continued to expand, and the proportion in newly built lines has exceeded 70%. To ensure the smoothness of the track, adjacent floating slabs are connected through shared bearing isolators. Shared bearing isolators integrate cylindrical isolators with supporting structures, which can both disperse the load and maintain line continuity.

[0003] However, since the floating plate adopts an over-static structural design (i.e., multiple support points work together to bear the load), when some steel springs age, rust or break due to unexpected situations such as water seepage and erosion, although the floating plate can still maintain a basically horizontal state due to the compensation effect of the remaining springs and supports when the train is running, the supporting force of the aged or rusted and broken steel spring on one side of the floating plate for the rails and the subway will be less than the supporting force provided by the steel spring on the other side of the floating plate, causing the unbalanced floating plate to tilt slightly under the dynamic load of the train (although the existing spring isolator under the floating plate has a certain ability to limit the deflection of the floating plate, in order to reduce the wear of its guide part, a gap is usually provided between the guide part and the floating plate, thereby allowing the floating plate to be slightly offset or deflected, preventing the floating plate from deflecting over a large distance, etc.), which will directly aggravate the geometric deformation of the track in severe cases, threatening the operation safety and causing safety hazards during the subway movement.

[0004] Existing methods for inspecting and maintaining steel spring floating plate tracks include daily inspection methods and periodic inspection methods. Both methods must be performed during train outages. The daily inspection method only observes the appearance of the steel spring isolator in a spot check manner to determine whether the steel spring is rusted or obviously deformed, etc., and is unable to troubleshoot invisible damage to the steel spring. In the periodic inspection method, it is only by detecting the height error of the floating plate that it is determined whether the steel spring isolator under the floating plate needs to be replaced. However, because the floating plate is always in a static state, even if individual steel springs are aged and damaged, when the train is not running, the floating plate will not be significantly displaced under the support of other steel spring isolators, making it difficult for existing detection methods to promptly detect the failure of individual steel spring isolators, making it difficult to completely eliminate safety hazards. Summary of the invention

[0005] In order to overcome the disadvantage that it is difficult to detect the state of the steel spring under the floating plate when the floating plate is in a static state, resulting in potential safety hazards during the movement of the subway, the present invention provides a floating plate isolator dynamic performance detection and adjustment device.

[0008] Preferably, a curved surface section, an inclined surface section and a horizontal section are provided on a side of the pressure block close to the extrusion boss, and the curved surface section, the inclined surface section and the horizontal section are all used to contact the extrusion boss.

[0009] Preferably, the recording mechanism includes a centrally symmetrically distributed blocking member, the blocking member is slidably connected to the balanced sealing tube, the symmetrically distributed blocking members are respectively located on both sides of the sliding plug, a centrally symmetrically distributed pressure sensor is fixedly connected in the balanced sealing tube, a third elastic member is installed between the blocking member and the adjacent pressure sensor, a data processing module is provided on the connecting plate, the pressure sensor is used to detect the elastic force of the adjacent third elastic member, the pressure sensor is electrically connected to the data processing module, the data processing module converts the numerical value detected by the pressure sensor and the number of times the pressure sensor is triggered into the distance and number of times the blocking member moves.

[0010] Preferably, the sliding plug is provided with symmetrically distributed first flow holes and symmetrically distributed second flow holes, and a one-way valve is provided in the second flow hole. The connection directions of the one-way valves in the symmetrically distributed second flow holes are opposite, and the blocking member is used to block adjacent second flow holes.

[0011] Preferably, a flow area of ​​the first flow hole is smaller than a flow area of ​​the second flow hole.

[0012] Preferably, the sliding plug is equipped with symmetrically distributed first magnets, and the blocking member is equipped with second magnets, and the second magnets are magnetically attracted to the adjacent first magnets.

[0013] Preferably, the outer side of the balance sealing tube is rotatably connected with symmetrically distributed adjusting knobs, the adjusting knobs are threadedly connected with an adjusting plate, the sealing member is limitedly slidably connected with the adjusting plate, and the adjusting plate is used to adjust the position of the sealing member.

[0014] Preferably, the transmission rod is engraved with scales, and the balance sealing tube is fixedly connected with symmetrically distributed indicator rods, and the indicator rods mark the positions of the adjacent transmission rods by aligning with the scales on the adjacent transmission rods.

[0015] A floating plate isolator adjustment device is installed on the above-mentioned floating plate isolator dynamic performance detection device, including symmetrically distributed support seats, the support seats are fixedly connected to adjacent mounting seats, the support seats are fixedly connected to symmetrically distributed fixed tilting blocks, the support seats are slidably connected to symmetrically distributed oil filling pipes, the oil filling pipes are slidably connected to sliding sliders, an oil filling chamber is provided in the sliding slider, the oil filling pipe is connected to the adjacent oil filling chamber, oil is filled into the oil filling chamber through the oil filling pipe, the fixed tilting block has an inclined surface, the sliding slider slides along the inclined surface of the adjacent fixed tilting block, the relative position between the sliding slider and the adjacent fixed tilting block is adjusted, and the sliding slider is fixed with a vibration-damping rubber block.

[0016] The beneficial effects of the present invention are as follows: the present invention transmits the pressure on both sides of the floating plate to the sliding plug through two transmission rods, and then judges the balance state of the floating plate in the current use state according to the position of the sliding plug in the balance sealing tube; if the elastic force provided by the steel springs on both sides of the floating plate no longer maintains the balance state, the sliding plug deviates to the side of the balance sealing tube away from the aging or rusting and breaking of the steel spring.

[0017] The present invention adjusts the resistance of the sliding plug when it moves in different directions by setting the first flow hole and the second flow hole. If the steel springs on both sides of the floating plate are not damaged, and only the floating plate tilts and fluctuates back and forth, the sliding plug does not have enough time to squeeze the two blocking parts to move a long distance, and will be affected by the change of direction of the floating plate and move in the opposite direction. When the steel springs on both sides of the floating plate are aged and corroded, the floating plate always tilts in a single direction, so the sliding plug has enough time to move in a single direction. The moving distance of the sliding plug in a single direction is greater than the moving distance in a single direction during the above-mentioned reciprocating movement. Through the difference between the two different situations, it can be more accurately judged whether the steel spring is aged or damaged, thereby increasing the accuracy of the detection.

[0018] The present invention adopts an independent adjustment mechanism to separately adjust the height of the vibration-damping rubber block. Therefore, compared with the existing device, it can better adapt to the thickness of different floating plates, make the connection between the two floating plates smoother, and by adjusting the pressure in the oil injection chamber at different positions to the same value, the load force between all the vibration-damping rubber blocks and the floating plate can be kept balanced. Compared with the existing method of separately detecting after adjustment, it not only simplifies the steps of adjusting the height of the vibration-damping rubber block, but also ensures that the force of the entire floating plate is more balanced.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0022] Example 1

[0023] The present embodiment discloses a floating plate isolator dynamic performance detection device, which is used to detect the use status of steel springs on both sides of the floating plate according to the comparison of the elastic forces of the steel springs on both sides of the floating plate when the floating plate is subjected to force.

[0024] Reference Figure 1-Figure 5 The dynamic performance detection device includes two mounting seats 1 symmetrically distributed front and back. In this embodiment, the two mounting seats 1 are both provided with support frames for supporting the edges of adjacent floating plates. The two mounting seats 1 are both fixed to the ground by bolts (refer to Figure 1 ), the symmetrically distributed mounting seats 1 are fixedly connected to the connecting plate 2 by bolts, the right side of the mounting seat 1 is rotatably connected to the swing rod 3, and a first elastic member 31 is installed between the two, the first elastic member 31 is a torsion spring, the right side of the connecting plate 2 is fixedly connected to the balance sealing tube 4, and the balance sealing tube 4 is slidably connected to the sliding plug 5 (refer to Figure 3 and Figure 4 ), the balanced sealing tube 4 is slidably connected with two transmission rods 6 symmetrically distributed front and back, the sliding plug 5 is located between the symmetrically distributed transmission rods 6, the transmission rod 6 is slidably connected to the sliding plug 5, and a second elastic member 61 is installed between the two, the second elastic member 61 is a spring, the second elastic member 61 is located in the balanced sealing tube 4, a pressure block 7 is fixedly connected to the side of the transmission rod 6 away from the adjacent second elastic member 61, and a recording mechanism for recording the displacement state of the sliding plug 5 is provided in the balanced sealing tube 4.

[0025] The above arrangement can achieve: the swing rod 3 is driven by the up and down displacement of the adjacent sides of the floating plate, and by squeezing the adjacent pressure blocks 7, the adjacent pressure blocks 7 are moved in the horizontal direction. The two pressure blocks 7 respectively drive the adjacent transmission rods 6 to move in opposite directions, and the two transmission rods 6 respectively squeeze the sliding plug 5 through the adjacent second elastic members 61. At this time, if the compression amounts of the steel springs on both sides are consistent and both provide equal elastic forces to the rails, the downward displacement distances of the two sides of the floating plate are consistent, and the squeezing forces applied by the two second elastic members 61 to the sliding plug 5 are consistent. The sliding plug 5 maintains the initial position in the balance sealing tube 4 without moving. When there is aging or rusting and breaking of the steel spring on one side of the floating plate, the elastic force provided by the steel springs on both sides of the floating plate no longer maintains the balanced state, and the sliding plug 5 deviates to the side of the balance sealing tube 4 away from the aging or rusting and breaking of the steel spring.

[0026] Reference Figure 2 , Figure 3 and Figure 6 The swing rod 3 has a supporting pad 32 and an extrusion boss 33, which are respectively fixed to the two ends of the swing rod 3. The supporting pad 32 is a detachable and replaceable structure. The supporting pad 32 abuts against the floating plate, and the extrusion boss 33 abuts against the pressure block 7.

[0027] The above arrangement can achieve that: the swing rod 3 can maintain a state of being in contact with the pressure block 7 and the floating plate at the same time by replacing different support pads 32 .

[0028] Reference Figure 6 A curved section 71, an inclined section 72 and a horizontal section 73 are provided on the side of the pressure block 7 close to the extrusion boss 33. The curved section 71, the inclined section 72 and the horizontal section 73 are all used to contact the extrusion boss 33. The extrusion boss 33 is in contact with the curved section 71 in the initial state. The inclined section 72 is used to connect the curved section 71 and the horizontal section 73. The horizontal section 73 is a horizontal plane.

[0029] The above arrangement can achieve: the curved section 71 initially abuts against the extrusion boss 33 to reduce the impact of vibration on the floating plate and to squeeze the pressure block 7 by the swing rod 3 to move the distance; the inclined section 72 is used to enable the extrusion boss 33 to stably squeeze and push the pressure block 7 to move; and the horizontal section 73 is used to limit the extrusion boss 33 when the extrusion boss 33 swings to the extreme position.

[0030] Reference Figure 3-Figure 7 The recording mechanism includes two blocking members 8 that are centrally symmetrically distributed (from left to right, the symmetry center is located at the centroid of the sliding plug 5). In the initial state, both blocking members 8 are in contact with the sliding plug 5. The blocking members 8 are slidably connected to the balance sealing tube 4. The symmetrically distributed blocking members 8 are respectively located on both sides of the sliding plug 5. The balance sealing tube 4 is fixed with a centrally symmetrically distributed pressure sensor 81 (refer to Figure 5 and Figure 6), a third elastic member 82 is installed between the blocking member 8 and the adjacent pressure sensor 81, and a data processing module is provided on the connecting plate 2 (not shown in the figure, it is an existing device, powered by a battery, and has communication transmission methods such as Bluetooth / Zigbee), the pressure sensor 81 is used to detect the number of times the adjacent blocking member 8 moves, and the data processing module integrates common data processing functions such as data comparison, data storage and data conversion, which is used to assist the staff to collect and process various information on the operating status of the floating plate, and the data processing module is used to convert the value detected by the pressure sensor 81 and the number of times the pressure sensor 81 is triggered into the distance and number of times the blocking member 8 moves, so as to assist the staff to judge the data.

[0031] The above setting can be achieved: when the sliding plug 5 slides in the front and rear directions, taking the forward sliding as an example, the sliding plug 5 contacts the blocking piece 8 located on the front side and squeezes the blocking piece 8 located on the front side. At this time, the third elastic piece 82 on the blocking piece 8 is compressed and stored. The pressure sensor 81 determines the displacement distance of the sliding plug 5 by detecting the elastic force on the third elastic piece 82, and transmits the current state of the sliding plug 5 to the data processing module, so as to assist the staff in collecting the dynamic balance state of the floating plate when the train is running.

[0032] The working process of the floating plate isolator dynamic performance detection device in this embodiment is as follows: Installation process: The staff installs the two mounting seats 1 in the gap between the two floating plates, and makes the upper support frames of the two mounting seats 1 abut against the floating plates. Then the staff adjusts and replaces the support pads 32 to keep the support pads 32 abutting against the floating plates, squeezing the boss 33 into abutting against the curved section 71.

[0033] Working process: When the subway passes through the floating plate, the floating plate moves up and down due to gravity and vibration. At this time, taking the front swing arm 3 as an example, the support pad 32 on the swing arm 3 is squeezed by the floating plate and moves downward, causing the swing arm 3 to rotate, and the first elastic member 31 twists and accumulates force. The extrusion boss 33 on the swing arm 3 moves along the curved surface section 71 and the inclined surface section 72 on the pressure block 7 in sequence (when the steel spring is in good condition, the extrusion boss 33 will not contact the horizontal section 73), and pushes the pressure block 7 and the transmission rod 6 to move backward. The transmission rod 6 squeezes the sliding plug 5 backward through the second elastic member 61, and the second elastic member 61 is compressed and accumulates force.

[0034] If the steel springs on the front and rear sides of the floating plate are in good condition, the floating plate has two movement states at this time. One is that the front and rear sides move up and down at the same time. At this time, the sliding plug 5 is subjected to equal extrusion forces from the second elastic members 61 on both sides, so the sliding plug 5 does not move. In the other movement state, because the front and rear sides of the floating plate are subjected to different forces, the forces on the steel springs on the front and rear sides of the floating plate deviate, causing the floating plate to fluctuate back and forth in the front and rear directions (the fluctuation is slight and will not affect the stable operation of the train). At this time, if the floating plate tilts forward, the extrusion force on the sliding plug 5 by the front second elastic member 61 is greater than the extrusion force on the rear second elastic member 61, then the sliding plug 5 will move backward, and the sliding plug 5 squeezes the rear blocking member 8 to move backward together, so that the rear third elastic member 82 is compressed and stored, and the pressure sensor 81 detects the signal of the third elastic member 82, records the value and time of the elastic force change of the rear third elastic member 82, and uploads these two data to the data processing module.

[0035] When the floating plate changes from tilting forward to tilting backward during operation, the extrusion force exerted on the sliding plug 5 by the second elastic member 61 on the rear side is greater than the extrusion force exerted on the sliding plug 5 by the second elastic member 61 on the front side, and the sliding plug 5 slides toward the front side, squeezing the front side blocking member 8 to move together, and compressing the third elastic member 82 on the front side to accumulate force, and the front side pressure sensor 81 detects the signal of the adjacent third elastic member 82, records the value and time of the elastic force change of the front side third elastic member 82, and uploads these two data to the data processing module.

[0036] In the above process, even if the floating plate tilts alternately forward and backward, since the steel springs on the front and rear sides of the floating plate are in good condition, the floating plate will inevitably increase the elastic force of the front steel spring when it tilts forward, causing the steel spring to tilt backward. Therefore, the values ​​of the front and rear pressure sensors 81 collected by the data processing module (i.e., the compression distance and compression time of the third elastic members 82 on the front and rear sides) are difficult to increase the distance.

[0037] If the steel springs on the floating plate are aged and corroded, and the aging and corrosion of the steel springs on one side is greater than that of the steel springs on the other side (if serious aging and corrosion occur on both sides at the same time, the floating plate will no longer be in a suspended state, but will move down to a position close to the ground or in contact with the ground. At this time, the staff can easily find this phenomenon and perform maintenance, so it is not within the scope of discussion of this embodiment), then the floating plate will no longer be in a state of moving downward in a horizontal state at the front and rear sides. Even if the floating plate is not subjected to force, it is still in a nearly horizontal position, and during the passage of the subway, this section of the floating plate will always It is tilted toward the side where the steel spring is severely aged and corroded (because when the steel spring is severely aged and corroded, it is difficult to provide an upward force for the floating plate). Therefore, if part of the steel spring on the front side of the floating plate is aged and corroded, the floating plate will always tilt toward the front side, causing the sliding plug 5 to always be pushed backward by the second elastic member 61 on the front side. In the data collected by the data processing module, the time duration when the pressure sensor 81 on the rear side is triggered is significantly greater than the time duration when the pressure sensor 81 on the front side is triggered, and the maximum elastic force recorded on the third elastic member 82 on the rear side is also significantly greater than the maximum elastic force recorded on the third elastic member 82 on the front side.

[0038] Data collection and maintenance process: During the maintenance process, the staff connects to the Bluetooth on the data processing modules in each device through mobile terminals, collects and analyzes data, and determines whether the steel springs in the floating plates are aged, rusted, or broken based on the dynamic balance of each floating plate. This reduces the difficulty of detecting the steel springs in the floating plates, allowing the staff to repair and replace aged and damaged steel springs in a timely manner, reducing safety hazards during railway operation.

[0039] Example 2

[0040] The present embodiment discloses a floating plate isolator dynamic performance detection device, which, on the basis of the first embodiment, further has the function of adjusting the operating state of the sliding plug 5 to make it easier to reset, thereby increasing the accuracy of the present device.

[0041] Reference Figure 4 , Figure 5 and Figure 7 The sliding plug 5 and the sealing member 8 are both sealed and slidably connected with the balance sealing tube 4. The balance sealing tube 4 is filled with liquid (such as hydraulic oil). The sliding plug 5 is provided with two first flow holes 51 symmetrically distributed up and down and four second flow holes 52 symmetrically distributed up and down (refer to Figure 4), a third flow hole 84 is provided on the blocking member 8, and the third flow hole 84 is communicated with the adjacent first flow hole 51, so that the blocking member 8 does not block the adjacent first flow hole 51, and a one-way valve 53 is provided in the second flow hole 52, and the two one-way valves 53 on the upper side correspond to the blocking member 8 on the rear side, and can only allow the liquid to flow from the back to the front, and the two one-way valves 53 on the lower side correspond to the blocking member 8 on the front side, and can only allow the liquid to flow from the front to the back, and the blocking member 8 is used to block the two adjacent second flow holes 52.

[0042] The above arrangement can achieve the following: when the floating plate begins to fluctuate back and forth due to the force deviation of the steel springs on its front and rear sides, when the floating plate tilts forward, the pressure of the second elastic member 61 on the front side of the sliding plug 5 is greater than the pressure of the second elastic member 61 on the rear side, and the sliding plug 5 moves from back to front, and the sliding plug 5 drives the blocking member 8 on the rear side to move together, and the one-way valve 53 on the upper side is in a blocked state. At this time, the liquid can only flow forward through the two first flow holes 51, and the resistance of the sliding plug 5 to move backward increases. When the tilting state of the floating plate changes from tilting forward to tilting backward, the pressure of the second elastic member 61 on the rear side of the sliding plug 5 is increased. The force gradually increases to a value greater than the pressure of the second elastic member 61 on the front side, and the sliding plug 5 and the rear blocking member 8 move forward and reset together. The liquid can flow from front to back through the two first flow holes 51 and the two one-way valves 53 on the lower side. The resistance of the sliding plug 5 is reduced, so that the sliding plug 5 and the blocking member 8 are quickly reset forward. When the sliding plug 5 is completely reset, the sliding plug 5 moves forward and pushes the front blocking member 8 to move forward together. Then, because the state of the floating plate changes again, the sliding plug 5 is pushed by the second elastic member 61 on the front side. In the process of moving from front to back and resetting, the resistance of the sliding plug 5 also follows the principle of first large and then small. Then, in the above process, if the steel springs on both sides of the floating plate are not damaged, when the floating plate tilts back and forth, the sliding plug 5 does not have enough time to squeeze the front or rear blocking member 8 to move a long distance, and will be affected by the change of direction of the floating plate and move in the opposite direction. When the aging and rust degree of the steel spring on one side of the floating plate is greater than that of the steel spring on the other side, because the floating plate always tilts in a single direction, if the aging and rust degree of the steel springs on both sides is similar, the sliding plug 5 will move alternately to both sides, but the time it stays on one side will be significantly increased. When the aging and rust degree difference of the steel springs on both sides is large, because the floating plate When the sliding plug 5 is in motion, it only tilts toward the side where the steel spring is severely aged and corroded. Therefore, the sliding plug 5 has sufficient time to move in one direction. The moving distance of the sliding plug 5 in one direction is greater than the moving distance in one direction during the above-mentioned reciprocating movement. The number of times the sliding plug 5 moves in one direction will also increase significantly. By changing the moving distance of the sliding plug 5 in the above-mentioned two different situations, the aging or corroded state of the steel spring can be more accurately determined, and the movement state of the floating plate in the above-mentioned situation can be distinguished from the movement state of the floating plate in the normal state of the steel spring. By increasing the reliability of the data, the accuracy of the detection is increased.

[0043] Reference Figure 5 , the flow area of ​​the first flow hole 51 is smaller than the flow area of ​​the second flow hole 52 .

[0044] Reference Figure 4 and Figure 5The sliding plug 5 is equipped with four first magnets 54 symmetrically distributed in the upper and lower parts, and the sealing member 8 is equipped with second magnets 83 corresponding to the adjacent first magnets 54. The second magnets 83 and the adjacent first magnets 54 are magnetically attracted to each other. The elastic force of the third elastic member 82 is much smaller than the elastic force of the second elastic member 61, thereby reducing the influence of the elastic force of the third elastic member 82 itself on the two second elastic members 61 pushing the sliding plug 5 to move.

[0045] The above arrangement can achieve the following: when the sealing member 8 blocks the adjacent second flow hole 52, the second magnet 83 and the adjacent first magnet 54 are magnetically attracted to each other. At this time, the second magnet 83 and the adjacent first magnet 54 provide a force to maintain the tight fit between the sealing member 8 and the sliding plug 5, thereby reducing the probability that the sliding plug 5 and the sealing member 8 will release the blockage of the sliding plug 5 due to the influence of vibration caused by the small elastic force of the third elastic member 82 during the common movement of the sliding plug 5 and the sealing member 8.

[0046] Reference Figure 4 , Figure 5 and Figure 7 The outer side of the balance sealing tube 4 is rotatably connected to two adjusting knobs 9 symmetrically distributed front and back, the adjusting knob 9 is threadedly connected to an adjusting plate 91, and the blocking member 8 is limitedly slidably connected to the adjacent adjusting plate 91 (refer to Figure 5 and Figure 7 ).

[0047] The above arrangement can be achieved: the staff rotates the adjustment knob 9 to make the adjustment knob 9 drive the adjustment plate 91 to move forward and backward, and the adjustment plate 91 drives the adjacent blocking piece 8 to move forward and backward, thereby adjusting the initial position of the blocking piece 8, increasing the distance between the blocking piece 8 on one side and the sliding plug 5, and thereby increasing the difficulty of the sliding plug 5 contacting the blocking piece 8 on that side (that is, the sliding plug 5 needs to move a greater distance to contact the blocking piece 8). The above adjustment process is used to reduce the influence of the subway tilting to one side when turning when using floating plates to pave the inclined turning section of the subway, and the pressure of the steel spring on one side is always greater than the pressure of the steel spring on the other side. By increasing the distance between the blocking piece 8 on one side and the sliding plug 5, the probability of the blocking pieces 8 on the front and rear sides contacting the sliding plug 5 is relatively average, thereby increasing the reliability of the data collected by the device.

[0048] Reference Figure 4 and Figure 5 The transmission rod 6 is engraved with scales, and the balance sealing tube 4 is fixedly connected with symmetrically distributed indicator rods 10, which are used to mark the current position of the transmission rod 6.

[0049] The above arrangement can achieve: the staff can mark the initial position of the transmission rod 6 and observe whether the position of the transmission rod 6 changes during maintenance, so as to intuitively judge the state of the steel spring supporting the suspension board, and thereby judge the value of the accumulated error of the device during the maintenance interval, so as to adjust and replace the device in time, thereby increasing the reliability of the data collected by the device.

[0050] Example 3

[0051] The present embodiment discloses a floating plate isolator adjustment device, which is used to replace the support frame in Embodiment 1. On the basis of Embodiment 1, the floating plate isolator adjustment device also has the function of supporting two different floating plates.

[0052] Reference Figure 1-Figure 3 and Figure 8 A floating plate isolator adjustment device includes two support seats 11 symmetrically distributed front and back, the two support seats 11 are respectively fixed to adjacent mounting seats 1, the support seats 11 are fixed with two fixed tilting blocks 13 symmetrically distributed left and right, the support seats 11 are slidably connected with symmetrically distributed oil injection pipes 14 in the up and down directions, the oil injection pipes 14 are slidably connected with sliding blocks 15, the fixed tilting blocks 13 have inclined surfaces, the sliding blocks 15 slide along the inclined surfaces of the adjacent fixed tilting blocks 13 (the two are slidably connected through the slide groove and the protruding column), and the sliding blocks 15 are provided with an oil injection cavity 151 (refer to Figure 8 ), the oil injection pipe 14 is connected to the adjacent oil injection chamber 151 (with Figure 8 For example, the right side of the oil filling chamber 151 is connected to the outside, and the left side of the oil filling chamber 151 is connected to the oil filling pipe 14). When the oil filling pipe 14 injects hydraulic oil into the oil filling chamber 151, the sliding block 15 moves to the side close to the oil filling pipe 14. The oil filling pipe 14 is provided with a pressure transmitting device (an existing device, not shown in the figure. The pressure transmitting device is provided with a battery, an oil pressure signal acquisition, and a processing and transmission component, which regularly converts the hydraulic oil signal into an electrical signal and sends it to the data processing module). A vibration-damping rubber block 16 is fixedly connected to the upper side of the sliding block 15, and the upper side surface of the vibration-damping rubber block 16 abuts against the floating plate.

[0053] The above arrangement can be achieved: the staff injects oil into the oil injection chamber 151 through the oil injection pipe 14, so that the sliding slider 15 moves to the side close to the adjustment oil injection pipe 14. When the sliding slider 15 slides back and forth relative to the support seat 11, the sliding slider 15 is guided by the fixed tilting block 13 to slide up and down at the same time, and the height of the vibration-damping rubber block 16 is adjusted, so that the vibration-damping rubber block 16 effectively supports the floating plate (rather than excessive squeeze support or no contact with the floating plate). In addition, this embodiment adopts an independent adjustment mechanism to separately adjust the height of the vibration-damping rubber block 16, so it can better adapt to the existing device. In response to the errors between different floating plates, the connection between the two floating plates is made smoother. When the floating plate moves downward, the vibration-damping rubber block 16 realizes the vibration and noise reduction function by compressing and storing force. The pressure transmitter detects the pressure in the oil filling chamber 151 (the pressure in the oil filling chamber 151 increases with the increase of the squeezing force between the support and the floating plate), and adjusts the pressure in the oil filling chamber 151 at different positions to the same value, so that the load force between all the vibration-damping rubber blocks 16 and the floating plate can be kept balanced. The above method not only simplifies the steps of adjusting the height of the vibration-damping rubber block 16, but also ensures that the force on the entire floating plate is more balanced.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
