Description

Technical Field

[0001] This utility model belongs to the technical field of railway maintenance equipment, specifically relating to a displacement observation device for seamless high-speed railway tracks based on CPⅢ piles. Background Technology

[0002] Seamless tracks for high-speed railways, with their advantages of high smoothness and stability, have become one of the core technologies in modern high-speed railway construction. Track displacement (including vertical settlement and lateral offset) directly affects train safety and comfort. Affected by factors such as temperature changes, train loads, and geological settlement, seamless tracks are prone to cumulative displacement. If not monitored and addressed promptly and accurately, this can lead to track deformation, fastener failure, and other defects. Therefore, routine displacement monitoring is necessary, relying on the CPⅢ control network (the plane control network for high-speed railway ballastless track construction).

[0003] Currently, seamless track displacement observation based on CPⅢ piles is mainly achieved through a combination of equipment such as collimators, reflectors, and levels. The core is to measure the positional change of the track relative to the CPⅢ piles by coordinating the collimator and reflectors. However, existing observation devices have many shortcomings in practical applications: First, the design of the fixing structure between the device and the rail is unreasonable. Some rigid clamps are prone to damaging the rail surface, while others lack stability, making the device prone to loosening during observation and leading to measurement errors. Second, the horizontal adjustment operation after the collimator is installed is cumbersome, lacking a convenient fine-tuning mechanism, making it difficult to quickly and accurately achieve a horizontal observation state, affecting observation efficiency. Third, the sliding component of the reflector is poorly designed, prone to deflection or jamming during sliding, making it impossible to ensure that the reflector's movement trajectory is completely parallel to the rail direction, further increasing measurement deviation. Fourth, the overall device is inconvenient to assemble and disassemble, with low integration of components and poor portability, which is not conducive to continuous observation operations at multiple measurement points in the field.

[0004] The aforementioned problems make it difficult for existing observation technologies to simultaneously achieve measurement accuracy, operational efficiency, and rail protection requirements, thus hindering the routine and precise implementation of displacement monitoring on seamless high-speed railway tracks. Therefore, it is necessary to develop a displacement observation device that is securely fixed, easy to adjust, stable in sliding, and causes no damage to the rails. Utility Model Content

[0005] This invention addresses the technical problems existing in the prior art by providing a displacement monitoring device for seamless high-speed railway tracks based on CPⅢ piles.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a displacement observation device for seamless high-speed railway lines based on CPⅢ piles, comprising a long strip block, clamping components installed on both sides of the bottom surface of the long strip block, a support component installed on one side of the top surface of the long strip block, a long strip plate fixedly installed on the top surface of the support component, an adjustment component installed on the other side of the top surface of the long strip block, a placement plate installed in conjunction with the adjustment component, a connecting component installed on the top surface of the placement plate, a sliding component slidably installed on the top surface of the long strip plate, and a magnetic base fixedly installed on the top surface of the sliding component.

[0007] Preferably, the clamping assembly includes multiple sets of placement slots formed on the bottom surface of the long strip block. Each set of placement slots consists of two placement slots arranged in a front-to-back pattern. Two placement slots in each set are located at the front and rear ends of the long strip block, respectively. A set of through holes is formed on each side of the long strip block. Each set of through holes consists of two through holes arranged in a front-to-back pattern. One end of each through hole is connected to the outside, and the other end is connected to the inside of the placement slot. A lead screw is rotatably installed inside the through hole. Two connecting holes are formed inside the long strip block. Each connecting hole is located between two placement slots in the same set of placement slots. Two lead screws located on the same longitudinal center line and arranged in a front-to-back pattern are fixedly connected by a connecting rod located inside the connecting hole. The two lead screws located on the same longitudinal center line have opposite threads. A lead screw nut is threaded onto the lead screw, and a clamping component is installed at the bottom end of the lead screw nut.

[0008] Preferably, the clamping component includes an L-shaped clamping block, with the top surface of the horizontal block of the L-shaped clamping block fixedly connected to the bottom end of the lead screw nut.

[0009] Preferably, a rubber pad is fixedly installed on the inner surface of the L-shaped clamping block.

[0010] Preferably, the support assembly includes several support rods, the bottom end of which is fixedly connected to the top surface of the long strip block, and the top end of which is fixedly connected to the bottom surface of the long strip plate.

[0011] Preferably, the adjustment assembly includes several vertical threaded rods, the bottom end of which is fixedly connected to the top surface of the long strip block.

Adjusting nuts are installed on the threaded rods with thread engagement, and the adjusting nuts are located below the placement plate.

[0012] Preferably, the connecting component includes a fixing block with two threaded holes on its top surface, into which mounting bolts are fitted.

[0013] Preferably, the sliding assembly includes an elongated groove on the top surface of the elongated plate, a slider is slidably installed in the elongated groove, a connecting plate is fixedly installed at the top of the slider, and a magnetic base is fixedly installed on the top surface of the connecting plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: (1) Reliable clamping and strong protection: The rail is clamped synchronously by means of a two-way threaded screw and an L-shaped clamp, which is firmly fixed and not easy to loosen, ensuring the stability of the device during the observation process. The rubber pad on the inner surface of the L-shaped clamp avoids hard contact with the rail, effectively protecting the rail surface from damage, and conforms to the track equipment use specifications. (2) Precise and convenient horizontal adjustment: The adjustment component adopts a combination structure of threaded rod and adjusting nut. When used with a level, the horizontal state of the placement plate can be quickly and finely adjusted to ensure that the main body of the collimator is in the optimal observation posture. (3) The sliding trajectory is accurate and the disassembly and assembly are flexible: the sliding component restricts the sliding direction of the reflector through the cooperation of the long groove and the slider, ensuring that the moving trajectory is completely parallel to the direction of the rail, thus improving the accuracy of displacement measurement. The slider adopts a detachable design, which can be disassembled when not in use to reduce the overall weight of the device, making it convenient to carry and transport multiple measurement points in the field. (4) Efficient installation and disassembly with high integration: The connecting components are directly fixed to the collimator body by bolts, the mounting holes are precisely aligned, the disassembly and assembly operations are simple and efficient, the components of the device are integrated on a long strip, the structure is compact, and the overall assembly can be completed without additional auxiliary tools, which greatly improves the efficiency of observation operations.

Detailed Implementation

[0016] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1 The following is combined with Figures 1-7 The displacement monitoring device for high-speed railway seamless track based on CPⅢ piles in Example 1 is further described below, such as... Figure 1 As shown, it includes a long strip 1, clamping components are installed on both sides of the bottom surface of the long strip 1, a support component is installed on one side of the top surface of the long strip 1, a long strip plate 2 is fixedly installed on the top surface of the support component, an adjustment component is installed on the other side of the top surface of the long strip 1, a placement plate 3 is installed in conjunction with the adjustment component, a connecting component is installed on the top surface of the placement plate 3, a sliding component is slidably installed on the top surface of the long strip plate 2, and a magnetic base 4 is fixedly installed on the top surface of the sliding component.

[0019] The clamping assembly clamps the rail, the long strip 1 is located on the top surface of the rail, a reflector is installed on the top surface of the magnetic base 4, the collimator body is installed on the placement plate 3, the collimator body is fixed by the connecting assembly, and the adjusting assembly adjusts the horizontal state of the placement plate 3 so that the collimator body is in a horizontal state. Place the long strip 1 onto the rail, with its bottom surface in contact with the top surface of the rail. Then, control the clamping assembly to clamp the rail and fix the long strip 1 onto it. At this point, the long strip 1, the long strip plate 2, and the top surface of the rail are parallel to each other. Then, install the reflector and the collimator body respectively. After installation, adjust the level of the placement plate 3 so that the collimator above is in a horizontal state. Complete the adjustment of the collimator and reflector, and the connection of the collimator to the computer. Mark the measurement points on the long strip plate 2 with a pen. The sliding assembly drives the magnetic base 4 and the reflector to slide on the long strip plate 2. The sliding assembly stops at the measurement points to measure the value, which is displayed on the computer. Since the rail and the long strip plate 2 are in a horizontal state, the sliding of the reflector on the long strip plate 2 can measure the change in the height of the rail.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the clamping assembly includes multiple sets of placement slots 5 formed on the bottom surface of the long strip block 1. Each set of placement slots consists of two placement slots arranged in a front-to-back manner. Two placement slots in the placement slot set 5 are located at the front and rear ends of the long strip block 1, respectively. A set of through holes 6 is formed on each side of the long strip block 1. Each set of through holes 6 consists of two through holes arranged in a front-to-back manner. One end of the through hole is connected to the outside, and the other end of the through hole is connected to the inside of the placement slot. A lead screw 7 is rotatably installed in the through hole. Two connecting holes 8 are formed in the long strip block 1. Each connecting hole 8 is located between two placement slots in the same set of placement slots 5. Two lead screws 7 located on the same longitudinal center line and arranged in a front-to-back manner are fixedly connected by a connecting rod 9. The connecting rod 9 is located in the connecting hole 8. The two lead screws 7 located on the same longitudinal center line have opposite threads. A lead screw nut is threaded on the lead screw 7, and a clamping component is installed at the bottom end of the lead screw nut.

[0021] A set of placement slots 5 and a set of through holes 6 are located on the same transverse center line. The two placement slots are located between the two through holes. The lead screw 7 is connected to the through hole through a bearing. The outer circumference of the lead screw 7 is fixedly connected to the inner wall of the inner ring of the bearing. The outer wall of the outer ring of the bearing is fixedly connected to the inner wall of the through hole. The two lead screws 7 located on the same longitudinal center line can rotate one of the lead screws 7, which can drive the two lead screws 7 to rotate synchronously through the connection of the connecting rod 9. This controls the movement of the lead screw nut in the placement slot, thereby controlling the relative movement or movement in opposite directions of the two lead screw nuts. This drives the two sets of clamping parts to move relative to each other or in opposite directions. The two sets of clamping parts are located at the front and rear ends of the rail respectively, clamping the rail and installing the long strip 1 on the rail.

[0022] like Figure 3 As shown, the clamping component includes an L-shaped clamping block 11, the top surface of which is fixedly connected to the bottom end of the lead screw nut.

[0023] The bottom surface of the horizontal block of the L-shaped clamping block 11 contacts the top surface of the rail. Rotating the screw 7 controls the screw nut to move in the placement groove, controlling the two L-shaped clamping blocks 11 on the same longitudinal center line to move relative to each other or in opposite directions, so that the two L-shaped clamping blocks 11 clamp the rail and install the long strip 1 on the rail.

[0024] like Figure 7 As shown, a rubber pad is fixedly installed on the inner surface of the L-shaped clamping block 11.

[0025] The inner surface of the L-shaped clamp 11 faces the rail. Rubber pads are installed on the bottom surface of the horizontal block and the inner surface of the vertical block of the L-shaped clamp 11. The rubber pads contact the rail to prevent the L-shaped clamp 11 from making hard contact with the rail and to protect the rail.

[0026] like Figure 1 and Figure 2 As shown, the support assembly includes several support rods 12, the bottom end of the support rods 12 is fixedly connected to the top surface of the long strip 1, and the top end of the support rods 12 is fixedly connected to the bottom surface of the long strip 2.

[0027] Supported by the support rod 12, the long strip 2 is fixedly connected to the long strip block 1, so that the long strip 2 remains stable during use.

[0028] like Figure 4 As shown, the adjustment assembly includes several vertical threaded rods 13. The bottom end of the threaded rods 13 is fixedly connected to the top surface of the long strip block 1. Several through holes 14 are opened on the top surface of the placement plate 3. The threaded rods 13 pass through the corresponding through holes 14. Adjusting nuts 15 are installed on the threaded rods 13 with thread engagement. The adjusting nuts 15 are located below the placement plate 3.

[0029] The diameter of the adjusting nut 15 is larger than the diameter of the through hole 14. First, adjust the placement plate 3 to be at the same height as the long strip plate 2. Then, place a level on the top surface of the placement plate 3. Then, rotate the adjusting nut 15 to adjust the level of the placement plate 3. After adjusting the level of the placement plate 3, install the collimator body. In the second operation method, after the placement plate 3 is leveled, a nut can be screwed into the two threaded rods 13 at opposite corners so that the bottom end of the nut contacts the top surface of the placement plate to further fix the placement plate and prevent it from shaking.

[0030] like Figure 6 As shown, the connecting component includes a fixing block 16, with two threaded holes on the top surface of the fixing block 16, and mounting bolts 10 are fitted into the threaded holes.

[0031] Place the collimator body onto the fixing block 16, ensuring that the mounting holes on the collimator body are concentric with the threaded holes. Then rotate the bolt 10 until the head of the bolt contacts the collimator, thus mounting the collimator body onto the fixing block 16.

[0032] like Figure 3 As shown, the sliding assembly includes a long groove 17 formed on the top surface of the long plate 2, a slider is slidably installed in the long groove 17, a connecting plate 18 is fixedly installed on the top of the slider, and a magnetic base 4 is fixedly installed on the top surface of the connecting plate 18.

[0033] The slider slides within the long slot 17 without deflection. When in use, the slider is directly inserted into the long slot 17 to drive the upper reflector to slide. When not in use, the slider is disassembled to reduce the overall weight.

[0034] How to use: I. Fixed Operation of the Device 1. Place the long strip block stably on the top surface of the rail, ensuring that the bottom surface of the long strip block is completely in contact with the top surface of the rail, and place the slots precisely to correspond to the front and rear sides of the rail.

[0035] 2. Select any lead screw at the longitudinal center line, rotate the lead screw clockwise, and drive the two opposite-threaded lead screws in the same group to rotate synchronously through the linkage transmission.

[0036] 3. Observe the movement of the L-shaped clamp until the rubber pad on the inner surface of the L-shaped clamp is tightly attached to the side of the rail. Gently shake the long strip to confirm that there is no looseness, and the device is fixed (at this time, the long strip is parallel to the rail).

[0037] II. Collimator Installation and Horizontal Adjustment 1. Pick up the placement plate, align its through hole with the threaded rod on the long strip, and slowly slide it in so that the placement plate is placed on the threaded rod.

[0038] 2. Place a level in the center of the top surface of the placement board, ensuring that the level is stable and not tilted.

[0039] 3. Rotate the adjusting nuts on each threaded rod one by one. Tightening the nuts outward will raise the corresponding side plate, and tightening them inward will lower it, until the level indicator shows that it is completely level.

[0040] 4. Take two fixing nuts and screw them into the threaded rods at opposite corners, so that the bottom surface of the nuts fits tightly against the top surface of the placement plate, thus completing the reinforcement of the placement plate.

[0041] 5. Place the collimator body on the fixing block, align the collimator mounting holes with the threaded holes of the fixing block, tighten the bolts to fix the collimator, and then connect the data transmission cable between the collimator and the computer.

[0042] III. Reflector Installation and Measurement Point Marking 1. Insert the slider into one end of the long groove of the long plate, and push the slider back and forth 2-3 times to confirm that the sliding is smooth without jamming or deflection.

[0043] 2. Attach the reflector to the magnetic base on the top surface of the connecting plate, and adjust the angle of the reflector so that its surface is directly aligned with the direction of the telescope lens.

[0044] 3. According to the monitoring specifications or actual observation needs, mark the measurement points on the top surface of the long strip with a marker, keep the spacing between adjacent measurement points consistent, and number them.

[0045] IV. Displacement Observation Operations 1. Turn on the collimator power supply and computer data receiving software, check the equipment connection status, and ensure normal data transmission.

[0046] 2. Push the slider by hand to move the reflector along the long groove to the measurement point numbered 1, and then let the slider come to rest after aligning with the measurement point.

[0047] 3. Wait for the collimator measurement data to stabilize (usually 3-5 seconds). After confirming that the computer has successfully recorded the data at this point, push the slider to move to the subsequent measurement points in sequence and repeat the data recording operation.

[0048] 4. If the data at a certain measurement point is abnormal, first check whether the device is loose, whether the collimator is horizontal, and whether the reflector is offset. After troubleshooting, remeasure the point.

[0049] V. Disassembly and Storage of the Device 1. Turn off the power to the collimator, disconnect it from the computer, loosen the fixing bolts, remove the collimator and store it properly.

[0050] 2. Remove the reflector from the magnetic base, pull the slider out of the long slot, and separate the slider from the connecting plate.

[0051] 3. Rotate the lead screw counterclockwise to disengage the L-shaped clamp from the side of the rail and release the device from its fixation.

[0052] 4. Pick up the long block, remove the adjusting nut and fixing nut from the placement plate and threaded rod, and disassemble each component.

[0053] 5. Place all components into storage boxes according to their categories, avoiding collisions to fragile parts such as rubber pads and reflectors, and ensure proper moisture and dust protection.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
