Abstract
Description
Technical Field
[0001] This invention relates to the field of track monitoring equipment technology, and in particular to a quick-release track pressure sensor. Background Technology
[0002] The track is the core structural component that bears the train load and ensures safe operation; its stress state directly determines the operational stability, safety, and service life of the rail vehicle. Figure 1 As shown, rail X1 is installed on wooden sleepers X2, and the space between the sleepers X2 is the ballast. When the rail vehicle travels on rail X1, the web X3 of rail X1 is the core channel for force transmission, that is, the lower middle part of the web of rail X1. The vertical pressure and lateral impact force exerted by the rail vehicle on rail X1 will be transmitted to the web X3 through rail X1. The force distribution of the web X3 is relatively uniform and is minimally affected by local wear and ballast impurities. It can accurately reflect the overall pressure of rail X1 and accurately reflect its actual pressure state. Therefore, the force transmission module of the pressure sensor is placed against the lower middle part of the web X3 to monitor the force state of rail X1.
[0003] With the development of technology, technicians in related fields have also made a lot of optimizations to track pressure sensors. In order to make more accurate comparisons, Chinese patent with publication number CN217819121U discloses a track pressure sensor, including a sensor housing, a sensor body and a magnetic ring. The sensor body abuts against the track to monitor track damage. The sensor housing has a magnetic ring. When the sensor body abuts against the track, the track can generate magnetic attraction with the magnetic ring. The magnetic ring keeps the sensor body abutting against the track to monitor the track. It also includes a first fixing frame and a second fixing frame. The first fixing frame and the second fixing frame clamp the track and are fixed by screws to support and fix the sensor body.
[0004] However, the existing track pressure sensors described above have some shortcomings: 1. The existing technology described above fixes the pressure sensor directly to the rail. When the rail vehicle travels on the rail, the rail will vibrate violently. As a result, the first and second fixing brackets will be affected by the vibration, causing the threaded fixing to gradually loosen. This affects the fixing effect of the pressure sensor, causing the contact position between the pressure sensor's force transmission module and the rail to shift and deviate from the preset monitoring position, thus making it difficult to guarantee the accuracy of pressure monitoring.
[0005] 2. In addition, the pressure sensors provided by the above-mentioned existing technologies are limited by the installation method and can only monitor specific positions of the rail. They cannot be adjusted in height and level according to monitoring needs, thus they cannot adjust the monitoring position of the rail and have limitations.
[0006] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing installation methods of track pressure sensors. Summary of the Invention

Connecting blocks are installed on opposite sides of the two support plates. Two horizontal plates are symmetrically arranged on opposite sides of the two connecting blocks. Support blocks are slidably sleeved on the outside of the horizontal plates. Several support columns are staggered on opposite sides of the two horizontal plates with corresponding positions. Connecting holes for sliding through the support columns are opened at the ends of the horizontal plates.
[0010] As a preferred embodiment of the present invention, the adjusting unit includes two lead screws that rotate through the connecting block respectively. The support block is sleeved on the outer wall of the lead screws by a threaded connection. The opposite ends of the two lead screws are connected by a transmission assembly. A control assembly is installed after either lead screw passes through the connecting block and the support plate to drive the lead screw to rotate. The lead screw, in conjunction with the support block, controls the horizontal adjustment of the pressure sensor.
[0011] As a preferred embodiment of the present invention, the transmission assembly includes a mounting block installed at one end of a lead screw, with a cross spline provided at one end of the mounting block away from the lead screw, and a cross groove that mates with the cross spline at the other end of the lead screw. An annular guide plate is installed at the end of the lead screw to guide the cross spline, and the cross groove gradually expands outward from the side closest to the cross spline.
[0012] As a preferred technical solution of the present invention, the control component includes an adjusting rod, an adjusting rod is provided at the end of the lead screw passing through the support plate, a spline groove is provided at the end of the adjusting rod away from the lead screw, a spline shaft is slidably provided inside the spline groove, and a hexagonal nut is installed at the end of the spline shaft away from the adjusting rod. The sidewall of the support plate is evenly provided with multiple ring-shaped limiting plates. The limiting plates are V-shaped structures that fit with the outer corners of the hexagonal nuts. A receiving groove is opened on the side of the limiting plate near the spline shaft axis. A wedge block is installed inside the receiving groove through a support spring rod.
[0013] As a preferred embodiment of the present invention, a calibration block is installed on the side of the horizontal plate near the connecting block, and a support block is located on the side of the calibration block away from the connecting block.
[0014] As a preferred embodiment of the present invention, the reinforcement unit includes sliding cavities formed at both ends of the support plate, a push plate is slidably disposed inside the sliding cavity, a push spring rod is installed between the push plate and the inner wall of the sliding cavity, and a locking block abutting against the side wall of the wooden sleeper is installed at the end of the push plate away from the push spring rod through a fastening assembly.
[0015] As a preferred embodiment of the present invention, the upper end of the sliding cavity is provided with multiple through holes, the upper end of the push plate is provided with a slot with the same diameter as the through holes, and a limit pin is movably inserted into the through holes and the slot, and a counterweight is provided on the upper end of the limit pin.
[0016] As a preferred technical solution of the present invention, the fastening assembly includes two symmetrical linkage holes opened inside the push plate, an actuator is slidably arranged inside the linkage hole, the actuator is connected to the locking block, a threaded hole is opened at the end of the push plate away from the sliding cavity, and a transmission thread that meshes with the threaded hole is provided at the end of the actuator away from the sliding cavity. The outer wall of the actuator is fixedly fitted with a pulley column, and a notch is opened on the push plate. A toothed belt is rotatably installed inside the notch and fitted on the outer wall of the two pulley columns. The toothed belt slides and meshes with the two pulley columns. Multiple levers are evenly arranged on the outer wall of the toothed belt, and a damping ring with sliding fit is provided between the outer wall of the toothed belt and the side wall of the notch.
[0017] In summary, this application includes the following beneficial technical effects: I. In this invention, after the support plate is placed on the upper end of the wooden sleepers on both sides of the rail, the pressure sensor is raised, lowered, and leveled so that the force transmission module of the pressure sensor abuts against both sides of the rail web. Then, the support plate is fixed in place, thereby realizing the rapid installation and disassembly of the pressure sensor for changing the monitoring position, which is convenient to operate. In addition, installing the pressure sensor on the wooden sleepers can prevent the vibration of the rail from being directly transmitted to the pressure sensor, thereby preventing the pressure sensor from shifting or weakening the contact strength with the rail web under the action of vibration, which would affect the pressure monitoring accuracy.
[0018] Second, after the pressure sensor is fully fixed after the lifting and horizontal adjustment is completed, the present invention can effectively resist the vibration generated when the rail vehicle is running on the rail, ensure that the pressure sensor is always in the preset position, and thus ensure the stability of the pressure sensor in the process of monitoring the rail pressure, and prevent the pressure sensor from deviating and affecting the monitoring accuracy.
[0019] Third, this invention achieves initial positioning of the support plate by having the locking blocks at both ends abut against the side wall of the wooden sleeper, facilitating adjustment of the support plate's position. Subsequently, the toothed belt is controlled to rotate, which in turn drives the actuator rod to rotate. The actuator rod further engages the locking blocks with the wooden sleeper, achieving further fixation of the support plate. Thus, the pressure sensor is fixed and positioned by the support plate. The entire process requires no complex tools, and installation and disassembly are highly efficient and convenient. Then, the limiting pin is inserted into the through hole and slot, forming a rigid connection between the push plate and the support plate, thereby ensuring a rigid abutment between the locking blocks and the wooden sleeper. This effectively resists the vibration of the rail and the wooden sleeper and improves the stability of the support plate and the pressure sensor. Attached Figure Description

[0032] The following is in conjunction with the appendix Figures 1-10 The embodiments of the present invention will be described in detail below.
[0033] This application discloses a quick-installation rail pressure sensor. It should be noted that this quick-installation rail pressure sensor is mainly used during the installation of the rail pressure sensor 32. Technically, the support plate 1 abuts against the wooden sleeper X2 for limiting positioning, and the pressure sensor 32 is then raised, lowered, and leveled. This allows the force transmission module of the pressure sensor 32 to abut against both sides of the rail web X2 of the rail X1 for pressure monitoring. In particular, after the pressure sensor 32 is installed, it is fully fixed, effectively resisting vibrations generated when rail vehicles travel on the rail X1, ensuring that the pressure sensor 32 is always in the preset position and maintaining its pressure monitoring accuracy on the rail X1.
[0034] Reference Figure 2 and Figure 3As shown, a quick-installation rail pressure sensor includes a support plate 1, installed between two wooden sleepers X2, symmetrically arranged along the rail X1, and the support plate 1 can adapt to wooden sleepers X2 with different spacings; a crossbeam 2, set between the two support plates 1, and connected to the two support plates 1; a support block 3, installed on the crossbeam 2, with a pressure sensor 32 installed on the upper end of the support block 3 via a top support frame 31; an adjustment unit 4, installed on the crossbeam 2, used to adjust the spacing between the two support blocks 3, thereby adjusting the spacing between the pressure sensor 32 and the rail X1; and a reinforcement unit 5, set at both ends of the support plate 1, used to quickly fix the support plate 1 to the wooden sleepers X2, improving the stability of the support plate 1, the crossbeam 2, and the pressure sensor 32.
[0035] In the specific implementation process, firstly, two support plates 1 are placed on the upper ends of wooden sleepers X2 on both sides of the pressure monitoring position of rail X1. Then, support blocks 3 are installed on crossbeam 2. Next, crossbeam 2 is installed between the two support plates 1. Then, the support plates 1 and the two wooden sleepers X2 are supported and fixed by the reinforcement unit 5, so that the pressure sensor 32 can be quickly installed and easily disassembled. Then, the distance between the pressure sensor 32 and rail X1 is adjusted by the distance adjustment unit 4, so that the force transmission module of pressure sensor 32 abuts against both sides of the rail web X2 of rail X1 for real-time monitoring of the pressure on rail X1.
[0036] Continue to refer to Figure 3 As shown, in order to ensure that the force transmission module of the pressure sensor 32 can accurately abut against the rail waist X2, the pressure sensor 32 can also be adjusted in height in this embodiment. Specifically, the top support frame 31 has an elastic telescopic rod 311 in the middle. The outer walls of the two telescopic joints of the elastic telescopic rod 311 are fixedly fitted with fixing plates 312. The two fixing plates 312 are connected by threads and two double-headed self-locking screws 313 are threaded through them. The two double-headed self-locking screws 313 are symmetrically arranged along the top support frame 31.
[0037] In the specific implementation process, rotating the two double-ended self-locking screws 313, through the cooperation between the double-ended self-locking screws 313 and the fixing plate 312, can drive the elastic telescopic rod 311 to adaptively extend and retract, thereby causing the pressure sensor 32 to rise and fall according to the pressure monitoring position of the rail X1. It should be noted that the double-ended self-locking screws 313 are existing technology and can automatically lock after rotation, thereby preventing arbitrary rotation from changing the height of the pressure sensor 32. In addition, the elastic telescopic rod 311 itself has elastic support force, which is used to push the two fixing plates 312 to both sides through the telescopic joint, thereby increasing the thread friction between the fixing plate 312 and the double-ended self-locking screws 313, which can further limit and fix the double-ended self-locking screws 313, effectively resisting the vibration generated when the rail vehicle travels on the rail X1, and ensuring that the pressure sensor 32 is always at the set height.
[0038] Reference Figure 4 and Figure 5 As shown, since the support plate 1 is located on both sides of the rail X1, when installing the crossbeam 2, it needs to be connected to the two support plates 1 through the bottom of the rail X1. In order to facilitate the connection of the crossbeam 2, in this embodiment, the crossbeam 2 is composed of a connecting block 21, a horizontal plate 22 and a support column 23. The two support plates 1 are each equipped with a connecting block 21 on opposite sides. Two horizontal plates 22 are symmetrically arranged on opposite sides of the two connecting blocks 21. The support block 3 is slidably sleeved on the outside of the horizontal plate 22. Several support columns 23 are staggered on opposite sides of the two horizontal plates 22 with corresponding positions. The end of the horizontal plate 22 is provided with a connecting hole for sliding through the support column 23. In order to facilitate the quick and accurate docking of the support column 23 and the connecting hole, in this embodiment, the end of the support column 23 near the connecting hole is a tapered structure with a gradually decreasing diameter.
[0039] In the specific implementation process, the horizontal plate 22 is first installed on the connecting block 21, then the connecting block 21 is installed on the support plate 1, and then the support block 3 is sleeved on the outside of the horizontal plate 22. When the two horizontal plates 22 are connected to each other, several support columns 23 are inserted into the connecting holes. Through the cooperation of the support columns 23 and the connecting holes, the opposite ends of the two horizontal plates 22 can be supported, so that the two horizontal plates 22 are on the same horizontal plane. This not only ensures the stability of the beam 2, but also ensures that the support block 3 will not cause the pressure sensor 32 to have a height deviation when it moves along the horizontal plate 22.
[0040] Reference Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in order to facilitate the support block 3 to drive the pressure sensor 32 to move along the horizontal plate 22 and realize the horizontal adjustment of the pressure sensor 32, a corresponding adjustment unit 4 is provided in this embodiment. Specifically, the adjustment unit 4 includes two lead screws 41 that respectively rotate through the connecting block 21. The support block 3 is sleeved on the outer wall of the lead screw 41 by a threaded connection. The opposite ends of the two lead screws 41 are connected by a transmission component 42. After passing through the connecting block 21 and the support plate 1, a control component 43 is installed on either lead screw 41 to drive the lead screw 41 to rotate. The lead screw 41 cooperates with the support block 3 to control the horizontal adjustment of the pressure sensor 32. The support block 3 can be limited in the direction of rotation under the action of the horizontal plate 22. Therefore, when the lead screw 41 is rotated, it can drive the support block 3 to move horizontally.
[0041] Furthermore, in this embodiment, the transmission assembly 42 includes a mounting block 421 installed at the end of one of the lead screws 41. The end of the mounting block 421 away from the lead screw 41 is provided with a cross spline 422. The end of the other lead screw 41 is provided with a cross groove that mates with the cross spline 422. An annular guide plate 423 is installed at the end of the lead screw 41 to guide the cross spline 422, so that the cross spline 422 is smoothly inserted into the cross groove under the action of the annular guide plate 423. The side of the cross groove near the cross spline 422 gradually expands outward to facilitate the smooth insertion of the cross spline 422 into the cross groove.
[0042] Furthermore, in this embodiment, the control component 43 includes an adjusting rod 431. An adjusting rod 431 is provided at the end of the lead screw 41 passing through the support plate 1. A spline groove 432 is provided at the end of the adjusting rod 431 away from the lead screw 41. A spline shaft 433 is slidably disposed inside the spline groove 432. A hexagonal nut 434 is installed at the end of the spline shaft 433 away from the adjusting rod 431. Multiple annularly distributed limiting plates 435 are evenly arranged on the sidewall of the support plate 1, limiting... Plate 435 is a V-shaped structure that fits against the outer corner of hexagonal nut 434. A receiving groove is provided on the side of the limiting plate 435 near the axis of spline shaft 433. A wedge block 437 is installed inside the receiving groove through a support spring rod 436. The support spring rod 436 always applies a driving force to the wedge block 437, so that the wedge block 437 moves towards one side of the axis of spline shaft 433 in the initial state and abuts against the side of hexagonal nut 434 away from spline shaft 433.
[0043] In the specific implementation process, when the connecting block 21 drives the two horizontal plates 22 to connect, it drives the two lead screws 41 to connect synchronously. One lead screw 41 drives the cross spline 422 to insert into the cross groove of the other lead screw 41. Through the mutual cooperation between the cross spline 422 and the cross groove, the two lead screws 41 can rotate synchronously. The two horizontal plates 22 and the two lead screws 41 can maintain the abutment state under the action of the support plate 1, and there will be no separation.
[0044] Pull the hexagonal nut 434 away from the adjusting rod 431. Then, rotate the splined shaft 433 through the hexagonal nut 434. The splined shaft 433, in conjunction with the spline groove 432, drives the adjusting rod 431 and the lead screw 41 to rotate synchronously. The helical directions of the outer threads of the two lead screws 41 are opposite. Therefore, when the lead screw 41 rotates, it can drive the two pressure sensors 32 to move synchronously relative to each other or in opposite directions through the support block 3, thereby simultaneously adjusting the distance between the two pressure sensors 32 and the rail X1. After adjustment, press the hexagonal nut 434. The wedge block 437 has a triangular cross-section, and the inclined surface of the wedge block 437 abuts against the outer side of the hexagonal nut 434. Therefore, when pulling and pressing the hexagonal nut 434, the hexagonal nut 434 can push the wedge block 437 to the side. The screw 434 is pushed into the receiving groove by the 37, thus making room for the hexagonal nut 434. The hexagonal nut 434 is then engaged between multiple limiting plates 435, which limit the rotation direction of the hexagonal nut 434. The hexagonal nut 434, through the cooperation between the spline shaft 433 and the spline groove 432, can limit the rotation direction of the lead screw 41, preventing the lead screw 41 from rotating arbitrarily and changing the position of the pressure sensor 32, ensuring that the pressure sensor 32 remains in the preset position. Multiple wedge blocks 437 can limit the horizontal movement direction of the hexagonal nut 434, thereby fully limiting the hexagonal nut 434 and preventing it from moving out of the inside of the wedge blocks 437 and rotating, thus changing the distance between the pressure sensor 32 and the rail X1 and preventing the impact on the pressure monitoring accuracy of the rail X1.
[0045] It should be noted that the length of the spline groove 432 is greater than the horizontal movement length of the spline shaft 433. Therefore, when the hexagonal nut 434 is pulled out, the spline shaft 433 will not fall out of the spline groove 432, and the torque transmission of the hexagonal nut 434 to the adjusting rod 431 and the lead screw 41 can still be maintained.
[0046] It should be further explained that a calibration block 221 is installed on the side of the horizontal plate 22 near the connecting block 21, and the support block 3 is located on the side of the calibration block 221 away from the connecting block 21. The initial position of the support block 3 can be positioned by the calibration block 221. That is, after the support block 3 is installed on the horizontal plate 22, it slides towards the side near the connecting block 21 and abuts against the calibration block 221. Under the action of the lead screw 41, it will not move away from the calibration block 221. Therefore, after the horizontal plate 22 and the lead screw 41 are connected, the positions of the two support plates 1 are adjusted so that the distance between the two pressure sensors 32 and the rail X1 is equal, so as to adjust the synchronous horizontal movement of the two pressure sensors 32, which can effectively improve the adjustment efficiency. When adjusting the position of the support plates 1, measuring tools can be used to further save operation time and improve accuracy.
[0047] Reference Figure 9 and Figure 10As shown, in order to improve the stability of the pressure sensor 32 during the monitoring process, the pressure sensor 32 is stably supported by the limiting fixation of the support plate 1 in this embodiment. Specifically, the reinforcement unit 5 includes sliding cavities 51 opened at both ends of the support plate 1. A push plate 52 is slidably arranged inside the sliding cavity 51. A push spring rod 53 is installed between the push plate 52 and the inner wall of the sliding cavity 51. A locking block 55 that abuts against the side wall of the wooden sleeper X2 is installed at the end of the push plate 52 away from the push spring rod 53 through the fastening assembly 54. The push spring rod 53 always applies a pushing force to the push plate 52 away from the sliding cavity 51, so that the two push plates 52 inside the support plate 1 drive the two locking blocks 55 to extend outward respectively in the initial state.
[0048] Furthermore, in this embodiment, the upper end of the sliding cavity 51 is provided with a plurality of through holes 511, and the upper end of the push plate 52 is provided with a slot with the same diameter as the through holes 511. The through holes 511 and the slot are movably connected to a limit pin 512, and a counterweight block 513 is provided on the upper end of the limit pin 512.
[0049] Furthermore, in this embodiment, the fastening assembly 54 includes two symmetrically arranged linkage holes 541 inside the push plate 52. An actuator 542 is slidably arranged inside the linkage hole 541. The actuator 542 is connected to the locking block 55. A threaded hole is provided at the end of the push plate 52 away from the sliding cavity 51. A transmission thread that meshes with the threaded hole is provided at the end of the actuator 542 away from the sliding cavity 51. A pulley post 543 is fixedly sleeved on the outer wall of the actuator 542. A notch is provided on the push plate 52 to expose the pulley post 543 to the outside. A toothed belt 544 is rotatably installed inside the notch and sleeved on the outer wall of the two pulley posts 543. The toothed belt 544 slidably meshes with the two pulley posts 543. A plurality of levers 545 are evenly arranged on the outer wall of the toothed belt 544. A damping ring 546 with sliding fit is provided between the outer wall of the toothed belt 544 and the side wall of the notch.
[0050] In the specific implementation process, the locking blocks 55 at both ends of the support plate 1 are abutted against the opposite sides of the two wooden sleepers X2 to achieve the initial positioning of the support plate 1. Then, the abutment effect between the locking blocks 55 and the wooden sleepers X2 is temporarily released by pressing the push rod into the sliding cavity 51 to facilitate the adjustment of the position of the support plate 1. Subsequently, the toothed belt 544 is rotated by the lever plate 545. The toothed belt 544 drives the actuator rod 542 to rotate through the pulley column 543. The actuator rod 542 drives the locking blocks 55 to move away from the push rod through the cooperation of the transmission thread and the threaded hole. The movement of one side of plate 52 further abuts the locking block 55 against the wooden sleeper X2, thereby further fixing the support plate 1. The pressure sensor 32 is then limited and fixed by the support plate 1. No complicated tools are required throughout the process, and the installation and disassembly are efficient and convenient. After the toothed belt 544 completes its rotation, it is limited by the damping ring 546, preventing the actuator rod 542 from rotating arbitrarily. This ensures that the locking block 55 is always in contact with the wooden sleeper X2, preventing loosening. Thus, the adjustable locking block 55 can accommodate wooden sleepers X2 with different spacing.
[0051] Subsequently, the toothed belt 544 is rotated further, causing the actuator 542 to extend continuously. Under the reaction force of the wooden sleeper X2, the actuator 542 and the locking block 55 drive the push plate 52 to move into the sliding cavity 51, thereby adjusting the slot of the push plate 52 to coincide with the nearest through hole 511. Then, the limiting pin 512 is inserted into the through hole 511 and the slot. Under the action of the counterweight block 513, the limiting pin 512 will not be pulled upward, thus limiting and fixing the position of the push plate 52, so that a rigid connection is formed between the push plate 52 and the support plate 1, thereby ensuring that the locking block 55 and the wooden sleeper X2 are in rigid contact, which can effectively resist the vibration of the rail X1 and the wooden sleeper X2, and improve the stability of the support plate 1 and the pressure sensor 32.
[0052] During operation: First step: First, install the horizontal plate 22 on the connecting block 21, then install the connecting block 21 on the support plate 1, then put the support block 3 on the outside of the horizontal plate 22, and put the locking blocks 55 at both ends of the support plate 1 against the opposite sides of the two wooden sleepers X2 to achieve the initial positioning of the support plate 1. Then adjust the position of the support plate 1 so that the two horizontal plates 22 and the two lead screws 41 are respectively connected.
[0053] Step 2: Control the toothed belt 544 to rotate via the lever 545. The toothed belt 544 drives the actuator 542 to rotate via the pulley column 543. The actuator 542 drives the locking block 55 to further abut against the wooden sleeper X2, thereby further fixing the support plate 1 and limiting and fixing the pressure sensor 32.
[0054] Subsequently, the toothed belt 544 is rotated further, causing the actuator 542 to extend continuously. Under the reaction force of the wooden sleeper X2, the actuator 542 and the locking block 55 drive the push plate 52 to move into the sliding cavity 51, thereby adjusting the slot of the push plate 52 to coincide with the nearest through hole 511. Then, the limiting pin 512 is inserted into the through hole 511 and the slot, thereby limiting and fixing the position of the push plate 52, so that a rigid connection is formed between the push plate 52 and the support plate 1, which can effectively resist the vibration of the rail X1 and the wooden sleeper X2, and improve the stability of the support plate 1 and the pressure sensor 32.
[0055] Step 3: Pull the hexagonal nut 434 away from the adjusting rod 431 and drive the spline shaft 433 to rotate. The spline shaft 433, in conjunction with the spline groove 432, drives the adjusting rod 431 and the lead screw 41 to rotate synchronously. The helical directions of the outer threads of the two lead screws 41 are opposite. When the lead screw 41 rotates, it drives the two pressure sensors 32 to move synchronously relative to each other or in opposite directions, thereby adjusting the distance between the two pressure sensors 32 and the rail X1, so that the pressure sensors 32 move horizontally to the preset position. After the adjustment is completed, press the hexagonal nut 434. The hexagonal nut 434 is locked between multiple limit plates 435 to achieve a limit, preventing the lead screw 41 from rotating arbitrarily and changing the position of the pressure sensor 32. This ensures that the pressure sensor 32 is kept in the preset position and prevents it from rotating arbitrarily and changing the distance between the pressure sensor 32 and the rail X1, thus preventing the impact on the pressure monitoring accuracy of the rail X1.
[0056] Step 4: Rotate the two double-ended self-locking screws 313. The cooperation between the double-ended self-locking screws 313 and the fixing plate 312 can drive the elastic telescopic rod 311 to extend and retract adaptively, thereby driving the pressure sensor 32 to rise and fall according to the pressure monitoring position of the rail X1. Then, the double-ended self-locking screws 313 are limited and fixed by the elastic telescopic rod 311 and the fixing plate 312 to ensure that the pressure sensor 32 is always at the set height.
[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
