Description

Technical Field

[0001] This application relates to the field of road safety monitoring equipment technology, and in particular to a highway slope stability testing device. Background Technology

[0002] With the widespread use of highways, in order to overcome traditional geographical limitations, highways often need to be constructed in harsh environments. However, current technologies typically rely on manual monitoring or camera imaging for safety monitoring, which mitigates the risks associated with highway slope stability issues to some extent. However, manual monitoring cannot provide real-time updates, offering only intermittent monitoring with poor continuity. While camera imaging allows for real-time monitoring and remote operation, its accuracy is limited.

[0003] A search revealed that Chinese utility model patent CN208805162U discloses a data acquisition device for monitoring the stability of highway slopes based on the Internet of Things (IoT). The device includes field equipment and a remote information processing system. The field equipment consists of a column, a protective frame, a mounting base, a laser transmitter, and a beam receiver. The column is vertically installed on a fixed roadbed of the highway. This utility model offers advantages such as real-time remote monitoring and high data accuracy.

[0004] In implementing this application, the technology suffers from at least the following problem: the highway slope stability monitoring data acquisition device lacks flexibility, and due to the different shapes, slopes, and heights of different slopes, a fixed laser emitter may not be suitable for all types of slopes. Therefore, a highway slope stability detection device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a highway slope stability detection device, which has the advantages of easily adjusting the height of the laser emitter to adapt to slopes of different gradients and heights, thus solving the problem of poor flexibility in highway slope stability monitoring data acquisition devices.

[0006] In summary, this application provides the following technical solution: a highway slope stability detection device, including a laser emitting head installed on one side of a highway slope, wherein the laser emitting head is provided with a support structure on its exterior;

[0007] The support structure includes a shell and a mounting frame;

[0008] The housing is provided with a lifting mechanism, which includes a first drive motor fixedly disposed outside the housing, a lead screw rotatably mounted on the bottom wall inside the housing, a lifting sleeve threadedly connected to the outside of the lead screw and extending to the outside of the housing, and a first transmission assembly disposed outside the lead screw and on the output shaft of the first drive motor.

[0009] The mounting bracket is provided with an angle adjustment mechanism, which includes a second drive motor fixedly mounted on the mounting bracket, a rotating shaft rotatably mounted inside the mounting bracket, a connecting arm fixedly mounted on the outer surface of the rotating shaft, and a second transmission component mounted on the outside of the rotating shaft and on the output shaft of the second drive motor.

[0010] This application adopts the above-mentioned technical solution to add lifting and angle adjustment functions to the laser transmitter head, so as to realize lifting and angle adjustment. This not only allows for convenient adjustment of the height of the laser transmitter head to adapt to slopes with different slopes and heights, but also allows for convenient adjustment of the pitch and yaw angles of the laser transmitter head to adapt to slopes of different shapes and monitoring needs.

[0011] Furthermore, the housing is vertically installed on the fixed roadbed of the highway, and a beam receiving plate corresponding to the laser emitter is installed on the highway slope.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by setting up a beam receiving plate corresponding to the laser emitter on the highway slope, when the slope is displaced, the beam receiving plate will also be displaced, and the irradiation point of the laser emitter on the beam receiving plate will be shifted, thereby achieving the effect of stability detection.

[0013] Furthermore, the housing is hollow inside, and a through hole communicating with the upper surface is provided inside the housing. The top of the lifting sleeve is welded with a base that is bolted to the lower surface of the mounting bracket, and the base passes through the through hole.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the shell has a perforation, so that the lifting sleeve can perform up and down reciprocating lifting operations.

[0015] Furthermore, the first transmission assembly consists of a first worm and a first worm wheel. The first worm is fixedly mounted on the output shaft of the first drive motor, and the first worm wheel is fixedly mounted on the outer surface of the bottom end of the lead screw, and the first worm and the first worm wheel mesh with each other.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the locking of the laser emitter head after adjustment is achieved through the transmission characteristics of the worm and worm wheel, so that the laser emitter head can perform detection work better.

[0017] Furthermore, a limiting platform is fixedly installed on the inner wall of the housing, and a guide structure connected to the lifting sleeve is installed between the upper surface of the limiting platform and the inner top wall of the housing.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by setting the guide structure, the lifting sleeve can be limited, enabling it to rise and fall linearly, thereby improving the adjustment stability of the laser emitter.

[0019] Furthermore, the first drive motor is bolted to the outer surface of the housing, and the output shaft of the first drive motor extends into the interior of the housing. The mounting bracket is U-shaped, and the second drive motor is bolted to the inner bottom wall of the mounting bracket.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the shape of the mounting bracket is U-shaped, which facilitates the installation layout of the angle adjustment mechanism and reduces the installation range.

[0021] Furthermore, the rotating shaft bearing is installed inside the mounting bracket, and there are two connecting arms, which are symmetrically arranged. Both connecting arms are bolted to the outer surface of the laser emitter.

[0022] The beneficial effect of adopting the above-mentioned further solution is that by setting the bearing, the stable rotation adjustment of the shaft is ensured, thereby improving the stability during adjustment.

[0023] Furthermore, the second transmission assembly includes a second worm fixedly mounted on the output shaft of the second drive motor and a second worm wheel fixedly mounted on the outer surface of the middle part of the shaft, wherein the second worm meshes with the second worm wheel.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the locking of the laser emitter head after adjustment is achieved through the transmission characteristics of the worm and worm wheel, so that the laser emitter head can perform detection work better.

[0025] Compared with the prior art, this application provides a highway slope stability testing device, which has the following advantages:

[0026] 1. This highway slope stability detection device adds lifting and angle adjustment functions to the laser transmitter head to achieve lifting and angle adjustment. It can not only easily adjust the height of the laser transmitter head to adapt to slopes with different slopes and heights, but also easily adjust the pitch and yaw angles of the laser transmitter head to adapt to slopes with different shapes and monitoring needs. This effectively solves the problem of poor flexibility of highway slope stability monitoring data acquisition devices.

[0027] 2. This highway slope stability testing device, through the setting of the guide structure, realizes the limit of the lifting sleeve, so that it can rise and fall linearly, improving the adjustment stability of the laser emitter head. Through the transmission characteristics of worm gear and worm wheel, the laser emitter head is locked after adjustment, so that the laser emitter head can perform better testing work.

[0033] Please see Figure 1 A highway slope stability detection device includes a laser emitter 1 installed beside a highway slope, a housing 2 vertically mounted on a fixed roadbed of the highway, and a beam receiving plate corresponding to the laser emitter 1 installed on the highway slope. When the slope shifts, the beam receiving plate also shifts, causing the illumination point of the laser emitter on the beam receiving plate to deviate. The information acquisition module within the beam receiving plate generates a signal, which is transmitted wirelessly to the information receiving module and finally to the information control center for processing. A control box is fixedly mounted on the outer surface of the housing 2. It should be noted that the laser emitter 1 and the beam receiving plate are conventional devices known to the public in the prior art; therefore, their specific structural composition and working principle will not be described in detail here.

[0034] In this embodiment, a support structure is provided on the outside of the laser emitter 1; the support structure includes a housing 2 and a mounting bracket 4; at least two support legs are welded to the outer surface of the housing 2 to enhance the stability of the laser emitter 1 after installation.

[0035] To improve the flexibility of laser emitter 1, please refer to Figure 1 and Figure 3 In this embodiment, a lifting mechanism 3 is provided inside the housing 2. The lifting mechanism 3 includes a first drive motor 301 fixedly mounted outside the housing 2, a lead screw 302 rotatably mounted on the bottom wall of the housing 2, a lifting sleeve 303 threadedly connected to the outside of the lead screw 302 and extending to the outside of the housing 2, and a first transmission assembly disposed outside the lead screw 302 and on the output shaft of the first drive motor 301. The first transmission assembly consists of a first worm 304 and a first worm wheel 305. The first worm 304 is fixedly mounted on the output shaft of the first drive motor 301, and the first worm wheel 305 is fixedly mounted on the outer surface of the bottom end of the lead screw 302, and the first worm 304 and the first worm wheel 305 mesh. Through the transmission cooperation of the first drive motor 301, the first worm 304 and the first worm wheel 305, the lead screw 302 is driven to rotate. The rotation of the lead screw 302 drives the lifting sleeve 303 to move up and down, thereby adjusting the height of the laser emitter 1. The height of the laser emitter can be easily adjusted to adapt to slopes of different gradients and heights.

[0036] For details, please refer to Figure 3 The housing 2 is hollow inside, with a through hole communicating with the upper surface. A base 306, bolted to the lower surface of the mounting bracket 4, is welded to the top of the lifting sleeve 303, and extends through the through hole. The first drive motor 301 is bolted to the outer surface of the housing 2, and its output shaft extends into the housing 2. A detachable inspection cover is installed on the exterior of the housing 2.

[0037] To ensure stable lifting and lowering of the lifting sleeve 303, please refer to [link / reference needed]. Figure 3 A limiting platform 307 is fixedly installed on the inner wall of the housing 2. A guide structure 308, which connects to the lifting sleeve 303, is installed between the upper surface of the limiting platform 307 and the inner top wall of the housing 2. The guide structure 308 consists of a guide rod and a slider. The two ends of the guide rod are fixed to the upper surface of the limiting platform 307 and the inner top wall of the housing 2, respectively. The slider is bolted to the outer surface of the lifting sleeve 303 and slides onto the outer surface of the guide rod. By setting up the guide structure 308, the lifting sleeve 303 is limited, enabling it to rise and fall linearly, thus improving the adjustment stability of the laser emitter 1.

[0038] Please see Figure 2An angle adjustment mechanism 5 is provided on the mounting frame 4. The angle adjustment mechanism 5 includes a second drive motor 501 fixedly mounted on the mounting frame 4, a rotating shaft 502 rotatably mounted inside the mounting frame 4, a connecting arm 503 fixedly mounted on the outer surface of the rotating shaft 502, and a second transmission assembly disposed on the outside of the rotating shaft 502 and the output shaft of the second drive motor 501. The second transmission assembly includes a second worm 504 fixedly mounted on the output shaft of the second drive motor 501 and a second worm wheel 504 fixedly mounted on the outer surface of the middle part of the rotating shaft 502, with the second worm 504 meshing with the second worm wheel 504. Through the transmission cooperation of the second drive motor 501, the second worm 504, and the second worm wheel 505, the rotating shaft 502 is driven to rotate, thereby adjusting the angle of the laser emitter head 1. This not only allows the laser emitter head 1 to better align with the beam receiving plate but also improves the flexibility of the laser emitter head 1.

[0039] In addition, the transmission characteristics of the worm gear and worm wheel are used to lock the laser emitter 1 after adjustment, so that the laser emitter 1 can perform detection work better.

[0040] Specifically, the mounting bracket 4 is U-shaped, and the second drive motor 501 is bolted to the inner bottom wall of the mounting bracket 4. The rotating shaft 502 bearing is installed inside the mounting bracket 4, and there are two connecting arms 503, which are symmetrically arranged. Both connecting arms 503 are bolted to the outer surface of the laser emitter head 1.

[0041] The working principle of the above embodiments is as follows:

[0042] When using this highway slope stability detection device, the housing 2 is vertically set on the fixed roadbed of the highway, and then a beam receiving plate corresponding to the laser emitter 1 is set on the highway slope. When the slope is displaced, the beam receiving plate will also be displaced, and the irradiation point of the laser emitter on the beam receiving plate will shift. The information acquisition module inside the beam receiving plate can then generate a signal, which is sent to the information receiving module via a wireless network and finally sent to the information control center for processing.

[0043] When the laser emitter 1 needs to be adjusted, the lead screw 302 is rotated by the transmission cooperation of the first drive motor 301, the first worm 304 and the first worm wheel 405. The rotation of the lead screw 302 causes the lifting sleeve 303 to move up and down, thereby adjusting the height of the laser emitter 1. Then, the rotating shaft 502 is rotated by the transmission cooperation of the second drive motor 501, the second worm 504 and the second worm wheel 505, thereby adjusting the angle of the laser emitter 1. This not only makes the laser emitter 1 better correspond to the beam receiving plate, but also improves the flexibility of the laser emitter 1.
