Technical Field

[0001] The invention relates to the technical field of roadbed monitoring, in particular to a high-speed roadbed deformation safety monitoring device. Background Art

[0002] Highways usually pass through various terrains, and the deformation of the roadbed may be affected by many factors, such as geological conditions, climate factors, traffic loads, etc. In order to ensure the safe operation of highways, it is necessary to monitor the deformation of the roadbed in real time and accurately analyze the deformation data.

[0003] At present, common monitoring equipment includes static levels and monitoring equipment based on settlement magnetic rings. The principle of monitoring equipment based on settlement magnetic rings is to use the magnetism and relative position changes of the magnetic rings to monitor the settlement of the roadbed. When the roadbed settles, the position of the magnetic ring will change relatively. By measuring this relative change, the settlement amount can be calculated. It has a simple structure and high accuracy. However, it has certain limitations: it is difficult to stably embed the magnetic ring in a narrow hole, and the magnetic ring mainly monitors the settlement in the vertical direction, and it is difficult to monitor the deformation in the horizontal direction.

[0004] Therefore, it is necessary to provide a high-speed roadbed deformation safety monitoring device to solve the above problems. Summary of the invention

[0037] Example: Please refer to Figure 1-Figure 4In an embodiment of the present invention, a high-speed roadbed deformation safety monitoring device is provided, comprising:

[0038] The mounting tube 2 is vertically mounted in the mounting hole K, and the top of the mounting tube 2 is open;

[0039] A first magnetic ring 3, which is embedded in the interior of the mounting tube 2;

[0040] A measuring vertical rod 4 coaxially extends into the interior of the mounting tube 2, and a magnetic sensor 5 is distributed on the measuring vertical rod 4;

[0041] The mounting hole K is arranged on the highway roadbed, and a top hole L is opened on the upper surface of the mounting hole K, and the inner diameter of the top hole L is larger than the inner diameter of the mounting hole K;

[0042] A top seat 6 is provided on the top of the measuring vertical rod 4 , and the top seat 6 is cast in the top hole L accordingly.

[0043] The installation process includes the following steps:

[0044] S1. Reserve a mounting hole K on the highway roadbed and ensure that the diameter and depth of the mounting hole K meet the design requirements.

[0045] S2. A top hole L is opened on the upper surface of the mounting hole K. The inner diameter of the top hole L is larger than the inner diameter of the mounting hole K to facilitate the subsequent casting of the top seat 6.

[0046] S3. Embed the first magnetic ring 3 inside the installation tube 2, and vertically install the installation tube 2 in the installation hole K to ensure that the installation tube 2 is stable. Since the first magnetic ring 3 is fixed in the installation tube 2, the installation process is simpler and there is no need to directly embed the first magnetic ring 3 in the installation hole K, which reduces the difficulty and time of installation.

[0047] S4. A top seat 6 is arranged on the top of the measuring vertical rod 4 , and the measuring vertical rod 4 is coaxially extended into the interior of the mounting tube 2 .

[0048] S5. Cast the top seat 6 in the top hole L accordingly, ensuring that the top seat 6 is flush with the roadbed surface or slightly lower than the surface.

[0049] In this embodiment, the first magnetic ring 3 is fixed in the installation tube 2, avoiding the complicated operation of directly embedding the first magnetic ring 3 in the installation hole K, greatly simplifying the installation process, reducing the installation time and improving the work efficiency. In addition, the casting design of the top seat 6 also ensures the stable connection between the measuring vertical rod 4 and the roadbed surface.

[0050] Furthermore, a measuring crossbar 7 is pre-installed in the highway roadbed, and a buffer assembly 9 is provided at the free end of the measuring crossbar 7;

[0051] An annular groove 8 is formed on the outer side of the installation tube 2, a sliding sleeve 10 is slidably connected in the annular groove 8, a second magnetic ring 11 is embedded in the sliding sleeve 10, and the sliding sleeve 10 is used to connect the buffer assembly 9;

[0052] The second magnetic ring 11 is located below the first magnetic ring 3;

[0053] The length of the sliding sleeve 10 is smaller than the length of the annular groove 8 .

[0054] The outer side of the mounting tube 2 is provided with an annular groove 8, in which the sliding sleeve 10 is slidably connected, so that the sliding sleeve 10 can move along the axial direction of the mounting tube 2. The measuring crossbar 7 is preset in the high-speed roadbed, and a buffer component 9 is provided at its free end to provide buffering under certain circumstances and transmit deformation information.

[0055] More specifically, the buffer assembly 9 can provide vertical or horizontal buffering. When the measuring cross bar 7 is vertically displaced and deformed, the buffer assembly 9 will drive the sliding sleeve 10 to vertically displace until the sliding sleeve 10 reaches the displacement limit (limited by the annular groove 8). At this time, the buffer assembly 9 will provide a certain buffer in the vertical direction; and when the measuring cross bar 7 is laterally displaced and deformed, the buffer assembly 9 will move toward the sliding sleeve 10 or away from the sliding sleeve 10. At this time, the buffer assembly 9 will provide a certain buffer in the horizontal direction.

[0056] The transverse direction is the length direction of the measuring cross bar 7.

[0057] In addition, it should be noted that the second magnetic ring 11 is located below the first magnetic ring 3 and is connected to the buffer assembly 9 of the measuring crossbar 7. When deformation occurs deep in the roadbed, the measuring crossbar 7 and the buffer assembly 9 will move accordingly, driving the sliding sleeve 10 and the second magnetic ring 11 to move in the annular groove 8. By monitoring the movement of the second magnetic ring 11, the settlement state of the foundation at depth can be measured. Therefore, in conjunction with the first magnetic ring 3, comprehensive monitoring of the roadbed deformation can be achieved, improving the accuracy and reliability of monitoring.

[0058] In this embodiment, the buffer assembly 9 at least includes a claw 91;

[0059] A limiting groove 12 is opened on the outer side of the sliding sleeve 10 for clamping the claw 91. The limiting groove 12 includes an axial T-slot 121 and a circumferential T-slot 122 opened from the bottom of the sliding sleeve 10 and connected in sequence. The shape of the claw 91 corresponds to the axial T-slot 121 and the circumferential T-slot 122.

[0060] Among them, the limiting groove 12 is opened on the outside of the sliding sleeve 10, and is used to clamp the claw 91. This design enhances the connection stability between the buffer assembly 9 and the sliding sleeve 10. The limiting groove 12 includes an axial T-slot 121 and a circumferential T-slot 122 opened from the bottom of the sliding sleeve 10 and connected in sequence, which facilitates the quick connection between the limiting groove 12 and the claw 9. Specifically, during the installation process, the claw 91 is first aligned with the entrance of the axial T-slot 121, at which time the installation cylinder 2 moves down (the sliding sleeve 10 moves down accordingly), and then the installation cylinder 2 is rotated along the circumferential T-slot 122. Under the action of friction (friction between the installation cylinder 2 and the sliding sleeve 10), the sliding cylinder 10 rotates accordingly until the claw 91 is completely embedded in the circumferential T-slot 122.

[0061] In this embodiment, the buffer component 9 includes:

[0062] A claw 91, used for connecting the sliding sleeve 10;

[0063] A plurality of buffer holes 93 distributed in a circumferential array are provided on the claw 91, and an annular limiting groove is provided inside the buffer hole 93;

[0064] An elastic sleeve 94, which is embedded in the annular limiting groove;

[0065] The connecting member 92 has one end connected to the measuring cross bar 7 and the other end provided with a buffer rod 95 corresponding to the buffer hole 93 , and the buffer rod 95 passes through the elastic sleeve 94 .

[0066] In addition, two symmetrically arranged annular protrusions 96 are formed on the outer surface of the buffer rod 95 , and the annular protrusions 96 are located at the end of the elastic sleeve 94 .

[0067] Among them, the elastic sleeve 94 is embedded in the annular limiting groove, which plays a role of buffering and shock absorption. The annular limiting groove can limit the position of the elastic sleeve 94, which is convenient for the rapid installation of the elastic sleeve 94. The buffer rod 95 runs through the elastic sleeve 94. When the roadbed is deformed, the buffer rod 95 can move in the elastic sleeve 94 to realize the buffer function.

[0068] The outer surface of the buffer rod 95 is formed with two symmetrically arranged annular protrusions 96 , which are located at the ends of the elastic sleeve 94 and are used to limit the movement range of the buffer rod 95 in the elastic sleeve 94 to prevent it from falling out.

[0069] The design of the buffer component 9 combines multiple parts such as the claw 91, the buffer hole 93, the elastic sleeve 94, the connecting piece 92 and the buffer rod 95, thereby realizing the buffer function in the horizontal and vertical directions.

[0070] Furthermore, a bottom hole J is coaxially drilled at the bottom of the mounting hole K, a bottom rod 1 is embedded in the bottom hole J, and the bottom rod 1 is used to support the mounting tube 2.

[0071] The bottom rod 1 is a hollow structure and has a plurality of casting holes on the side. The top of the bottom rod 1 is connected to the installation tube 2.

[0072] Therefore, when installing the bottom rod 1 and the installation tube 2, the following steps are included:

[0073] S1. Reserve a mounting hole K on the highway roadbed and ensure that the diameter and depth of the mounting hole K meet the design requirements.

[0074] S2. Drill a bottom hole J coaxially at the bottom of the mounting hole K to ensure that the diameter and depth of the bottom hole J meet the design requirements.

[0075] S3. Insert the bottom bar 1 (the bottom bar 1 is pre-welded with the mounting tube 2) into the bottom hole J to ensure that the bottom bar 1 is stable and vertical. The hollow structure of the bottom bar 1 and the casting hole design on the side facilitate the subsequent casting connection with the roadbed material and enhance the stability of the bottom bar 1.

[0076] S4. Use roadbed materials (such as concrete, asphalt, etc.) to cast the bottom bar 1 to ensure that the bottom bar 1 is tightly combined with the roadbed material.

[0077] In this embodiment, the design of the bottom bar 1 ensures the stability of the mounting tube 2 in the mounting hole K, and improves the installation accuracy of the equipment. This helps to ensure the accurate position and direction of the measuring vertical bar 4 and the measuring cross bar 7, thereby improving the monitoring accuracy. The design of the bottom bar 1 provides additional support and stability for the highway roadbed deformation safety monitoring equipment, and improves the installation accuracy and monitoring accuracy of the equipment.

[0078] In this embodiment, the top of the measuring vertical rod 4 is connected to the top seat 6 by a pillar, the gap of the pillar is matched with the mounting hole K, and the gap between the lower surface of the pillar and the upper surface of the mounting tube 2 is equal to the gap between the lower surface of the measuring vertical rod 4 and the inner bottom surface of the mounting tube 2. In this way, the size of the gap space in the mounting hole K can be minimized on the basis of satisfying the settlement and movement of the measuring vertical rod 4, thereby improving the stability of the mounting hole K.

[0079] In addition, the top of the measuring vertical rod 4 is connected to the top seat 6 through a support. This connection method ensures the vertical stability of the measuring vertical rod 4, so that it can accurately reflect the vertical deformation of the roadbed.

[0080] In this embodiment, a strain gauge is embedded in the clamping claw 91, and the strain gauge provides direct data support for monitoring the lateral deformation of the roadbed, which enables the equipment to monitor the deformation of the roadbed more comprehensively, and improves the accuracy and reliability of monitoring.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
