[0001] The invention belongs to the field of tunnel construction devices, in particular to a tunnel construction monitoring device based on the Internet of Things. Background Art

[0002] The purpose of tunnel construction monitoring is to monitor the deformation, stress, strain, cracks, water leakage, etc. of the tunnel civil structure, as well as the internal environment of the tunnel such as air quality, lighting, temperature, tunnel diameter, and construction status data, and then judge the actual situation of the tunnel based on the data obtained. These monitoring devices require a variety of devices, which are selected according to the actual situation. Usually, these monitoring data are transmitted through the Internet of Things.

[0004] During the tunnel construction process, unstable tunnel locations require the use of reinforced concrete structures to increase additional strength and rigidity in order to withstand the stress caused by internal water pressure, geological conditions and other external factors. In this case, the equal spacing between the steel bars is more important. However, when traditional tunnel monitoring devices monitor and measure the internal diameter of the tunnel, it is not convenient to use tunnel diameter monitoring devices to help the steel bars to be arranged at equal spacing, which in turn affects the efficiency and effectiveness of steel bar construction.

[0011] Preferably, a through groove and two connecting grooves are formed through the interior of the cylinder, and an electric drive gear belt is movably installed inside the two connecting grooves.

[0012] Preferably, the horizontal telescopic assembly includes a plurality of fixed blocks and an electrically driven telescopic rod, adjacent fixed blocks are connected via a plurality of electrically driven telescopic rods, and a plurality of fixed blocks are placed inside the through groove.

[0013] Preferably, component grooves are provided on both sides of the fixing block, and tooth plates are fixedly installed on the inner walls of the component grooves, and the tooth plates are meshed with the electric drive gear belt.

[0014] Preferably, the elastic head comprises a connecting block and an elastic block fixedly mounted on a side of the connecting block, and the elastic block is a component made of an elastic material.

[0015] Preferably, cylindrical grooves are provided inside the connecting block and the elastic block, and impact test components are installed inside the cylindrical grooves. The impact test components are used for impact testing of the tunnel, and the data of the impact test is transmitted through the Internet of Things.

[0016] Preferably, the impact test assembly includes a telescopic motor fixedly mounted inside the connecting block and an impact head movably mounted inside the cylindrical slot, a pulling telescopic rod is mounted at the output end of the telescopic motor, and one end of the pulling telescopic rod is connected to the impact head.

[0017] Preferably, an electromagnet disc is installed at one end of the pulling telescopic rod, and the electromagnet disc is magnetically connected to the corresponding side of the impact head. A plurality of spring guide columns are installed on the same side of the impact head, and one end of the plurality of spring guide columns is installed on the inner wall of the cylindrical groove.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The tunnel construction monitoring device based on the Internet of Things described in the present invention horizontally adjusts the monitoring and detection component through an adjustable bracket to keep the monitoring and detection component in a horizontal state, and then extends the horizontal telescopic component under electric drive, that is, at this time, the overall length of the horizontal telescopic component increases until the elastic heads at both ends of the horizontal telescopic component are against the two inner walls of the tunnel, thereby stabilizing the position of the monitoring and detection component, and the overall length data of the extended horizontal telescopic component is transmitted through the Internet of Things, thereby monitoring the tunnel diameter at the construction location, and after the monitoring and detection component is stabilized, the relative elevation between different points is measured by rotating the construction level, which is very important for determining the elevation of the tunnel reinforced concrete construction, and after determining the relative elevation between the two points, the length of the steel structure is determined by the height difference between the two places, effectively accelerating the subsequent reinforced concrete construction efficiency.

[0020] 2. The tunnel construction monitoring device based on the Internet of Things described in the present invention changes the position of the laser surface emitted by the vertical laser emitter through the horizontal movement of the mobile component on the horizontal telescopic component. At this time, the adjustable bracket shrinks and no longer supports the ground, thereby ensuring the equidistant movement of the mobile component each time, thereby driving the equidistant movement of the laser surface of the vertical laser emitter. The steel structure can be equidistantly set according to this laser surface to effectively even out the tunnel stress. At this time, the data of the equidistant movement of the mobile component is transmitted through the Internet of Things, and the reinforced concrete structure data at the tunnel construction position is monitored, which is beneficial to subsequent tunnel construction projects.

[0021] 3. The tunnel construction monitoring device based on the Internet of Things described in the present invention generates magnetic force by energizing the electromagnet disc. At this time, the electromagnet disc is magnetically connected to the contact side of the impact head. The electric power drives the telescopic motor to drive the telescopic rod to contract, that is, the impact head moves toward the telescopic motor and gradually moves away from the inner wall of the tunnel, causing the spring guide column spring to be compressed. When one end of the impact head is a certain distance away from the inner wall of the tunnel, the electromagnet disc is no longer energized. Under the restoring force of the spring guide column spring, the impact head instantly moves toward the inner wall of the tunnel to impact the inner wall of the tunnel. The impact head is impacted on the inner wall of the tunnel multiple times in the same way to complete the impact test. The impact force of the impact head can be changed by pulling the telescopic rod to contract the distance. After the impact of the impact head, the telescopic rod is extended to energize the electromagnet disc and re-magnetically connect to the side of the impact head. At this time, the extension distance of the telescopic rod can test the impact resistance of the inner wall of the tunnel. The data of the extension of the telescopic rod can be transmitted through the Internet of Things, which can indicate the safety status in the tunnel to a certain extent, thereby completing the monitoring of the safety status of the inner wall of the tunnel.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1

[0034] like Figure 1-4As shown, a tunnel construction monitoring device based on the Internet of Things according to an embodiment of the present invention comprises an adjustable bracket 4, a mobile component 3 is movably installed above the adjustable bracket 4, a horizontal telescopic component 2 is movably installed inside the mobile component 3, and a monitoring and detection component 1 is movably installed above the mobile component 3;

[0035] The monitoring and detection component 1 includes a construction level 11 and a vertical laser emitter 12 installed on the side of the construction level 11. Elastic heads 5 are installed at both ends of the horizontal telescopic component 2. A data transmission module is arranged inside the construction level 11. The data transmission module is used to transmit the monitoring data through the Internet of Things, and the telescopic length data of the horizontal telescopic component 2 is transmitted through the Internet of Things.

[0036] Specifically, it is necessary to add reinforced concrete structures at unstable positions of the tunnel to enhance the strength and rigidity of the interior of the tunnel in order to withstand the stress caused by internal water pressure, geological conditions and other external factors. In order to evenly distribute the stress of the steel bars, it is necessary to set multiple steel bar structures at equal distances, and multiple steel bars under this installation method can be more evenly distributed inside the concrete, ensuring uniform filling during concrete pouring. When the construction personnel are in an unstable position of the tunnel, the adjustable bracket 4 is placed in the tunnel, and the monitoring and detection component 1 is horizontally adjusted by the adjustable bracket 4 to maintain the horizontal state of the monitoring and detection component 1. Then, the horizontal telescopic component 2 is extended by electric drive, that is, at this time, the overall length of the horizontal telescopic component 2 increases until the elastic heads 5 at both ends of the horizontal telescopic component 2 are against the two inner walls of the tunnel, thereby stabilizing the position of the monitoring and detection component 1, and the overall length data of the extended horizontal telescopic component 2 is transmitted through the Internet of Things, thereby controlling the construction personnel. The diameter of the tunnel at the construction location is monitored. After the monitoring and detection component 1 is stable, the relative elevation between different points is measured by rotating the construction level 11. This is very important for determining the elevation of the tunnel reinforced concrete construction. After determining the relative elevation between the two points, the length of the steel structure is determined by the height difference between the two places, which effectively speeds up the subsequent reinforced concrete construction efficiency. Then, the mobile component 3 is horizontally moved on the horizontal telescopic component 2. At this time, the adjustable bracket 4 shrinks and no longer supports the ground to change the position of the laser surface emitted by the vertical laser emitter 12, ensuring that the mobile component 3 moves equidistantly each time, thereby driving the equidistant movement of the laser surface of the vertical laser emitter 12. The steel structure can be equidistantly set according to this laser surface to effectively even out the tunnel stress. At this time, the data of the equidistant movement of the mobile component 3 is transmitted through the Internet of Things to monitor the reinforced concrete structure data at the tunnel construction location, which is beneficial to the subsequent tunnel construction project.

[0037] like Figure 2As shown, the adjustable bracket 4 includes a mounting head 41 and a trapezoidal groove 42 opened above the mounting head 41, a plurality of rotating brackets 43 are movably installed below the mounting head 41, a telescopic bracket 44 is movably installed below the plurality of rotating brackets 43, and a rubber triangular pad 45 is installed at the lower end of the telescopic bracket 44.

[0038] Specifically, the rotating bracket 43 can be rotated to adjust the angle. The angle adjustment of the three groups of rotating brackets 43 can make the monitoring and detection component 1 more stable. The telescopic bracket 44 can slide inside the corresponding rotating bracket 43 to adapt to different geological conditions in the tunnel. Different groups of telescopic brackets 44 have different sliding distances inside the corresponding rotating bracket 43, which effectively maintains the horizontal state of the monitoring and detection component 1. The rubber triangular pad 45 can be elastically deformed to adapt to small-volume gravel ground.

[0039] like Figure 4 As shown, a plurality of screw covers 13 are installed on the lower side of the monitoring and detecting component 1, the moving component 3 includes a cylinder 31 and a plurality of threaded columns 33 fixedly installed on the upper side of the cylinder 31, the plurality of threaded columns 33 are threadedly connected with the screw covers 13, a trapezoidal sheet 32 ​​is installed on the lower side of the cylinder 31, and the vertical laser emitter 12 is preferably a vertical cavity surface emitting laser for emitting a vertical laser plane.

[0040] Specifically, multiple spiral covers 13 can be screwed, and the monitoring detection component 1 and the mobile component 3 can be installed by screwing the spiral covers 13 to make them threadedly connected with the corresponding threaded columns 33. The trapezoidal piece 32 at the bottom of the mobile component 3 can be inserted into the trapezoidal groove 42 to complete the installation of the adjustable bracket 4 and the mobile component 3. The device can be disassembled, which is convenient for subsequent maintenance and installation. The disassembled device can be easy to carry.

[0041] like Figure 5-6 As shown, a through groove 34 and two connecting grooves 35 are formed inside the cylinder 31, and an electric drive gear belt 36 is movably installed inside the two connecting grooves 35. The horizontal telescopic assembly 2 includes a plurality of fixed blocks 21 and an electric drive telescopic rod 22. Adjacent fixed blocks 21 are connected by a plurality of electric drive telescopic rods 22. A plurality of fixed blocks 21 are placed inside the through groove 34. Component grooves 23 are formed on both sides of the fixed blocks 21. A tooth plate 24 is fixedly installed on the inner wall of the component groove 23, and the tooth plate 24 is meshed with the electric drive gear belt 36.

[0042] Specifically, the extension and retraction of the horizontal telescopic component 2 is mainly achieved by the extension and retraction of multiple electrically-driven telescopic rods 22. When the device is carried to tunnel, the multiple electrically-driven telescopic rods 22 inside the through-slot 34 are limited, while the other electrically-driven telescopic rods 22 are all retracted, that is, at this time, the footprint of the device becomes smaller, which is convenient for construction personnel to carry. The subsequent extension of the horizontal telescopic component 2 is also achieved by extending the multiple electrically-driven telescopic rods 22 except those inside the through-slot 34 to increase the overall length of the horizontal telescopic component 2. At this time, the length data of the extended multiple electrically-driven telescopic rods 22 can be transmitted through the Internet of Things, thereby confirming the overall length of the horizontal telescopic component 2. The extended length of the multiple electrically-driven telescopic rods 22 except those inside the through-slot 34 is a multiple length of the spacing between adjacent racks of the electrically-driven gear belt 36, that is, during the movement of the moving component 3, the electrically-driven gear belt 36 can always be engaged with the fixed block 21, and the movable arrangement inside the cylinder 31 The two electrically driven gear belts 36 are meshed with at least three fixed blocks 21 inside the cylinder 31 at the same time. When the length of the horizontal telescopic component 2 increases, that is, after the multiple electrically driven telescopic rods 22 except those inside the through-slot 34 are extended, the adjustable bracket 4 is retracted so that it is no longer in contact with the bottom surface. At this time, the adjustable bracket 4, the monitoring and detection component 1 and the moving component 3 are suspended in the air, and the electric drive electrically driven gear belt 36 is rotated. Because the length of the electrically driven gear belt 36 is greater than the maximum length of the three adjacent fixed blocks 21, after the electrically driven gear belt 36 rotates, the electrically driven gear belt 36 can be meshed with different fixed blocks 21, that is, the moving component 3 drives the monitoring and detection component 1 and the adjustable bracket 4 to move on the horizontal telescopic component 2. The displacement caused by the rotation of the electrically driven gear belt 36 can make the movement of the monitoring and detection component 1 more precise, and the precisely moved vertical laser emitter 12 can provide an important construction reference for the equidistant setting of the steel bars.

[0043] Embodiment 2

[0044] like Figure 7 As shown, compared with Example 1, another implementation of the present invention is: the elastic head 5 includes a connecting block 51 and an elastic block 52 fixedly installed on the side of the connecting block 51, the elastic block 52 is a component made of elastic material, and a cylindrical groove 53 is opened inside the connecting block 51 and the elastic block 52, and an impact test component 54 is installed inside the cylindrical groove 53. The impact test component 54 is used for impact testing of the tunnel, and the data of the impact test is transmitted through the Internet of Things.

[0045] Specifically, after the length of the horizontal telescopic component 2 is increased, the elastic blocks 52 at both ends of the horizontal telescopic component 2 will contact the tunnel wall, and the elastic blocks 52 will press against the tunnel wall. At this time, the elastic blocks 52 can be deformed to adapt to the unevenness of the inner wall of the tunnel. After the two elastic blocks 52 firmly press against the inner wall of the tunnel, the inner wall of the tunnel can be impact tested by the impact test component 54 to monitor the safety status of the tunnel and ensure that safe construction can be carried out inside the tunnel. This impact method can choose a force storage spring type solution, which converts the spring thrust from the compressed state to the natural state to push the column or hammer to impact the inner wall of the tunnel. The safety status of the tunnel can be observed by observing the crushing of the inner wall of the tunnel. The various data of the impact test and the crushing of the tunnel can be transmitted through the Internet of Things, and the internal situation of the tunnel can be monitored by summarizing the various data.

[0046] like Figure 8 As shown, the impact test assembly 54 includes a telescopic motor 542 fixedly installed inside the connecting block 51 and an impact head 541 movably installed inside the cylindrical slot 53, a pulling telescopic rod 543 is installed at the output end of the telescopic motor 542, one end of the pulling telescopic rod 543 is connected to the impact head 541, an electromagnet disc 544 is installed at one end of the pulling telescopic rod 543, the electromagnet disc 544 is magnetically connected to the corresponding side of the impact head 541, a plurality of spring guide columns 545 are installed on the same side of the impact head 541, one end of the plurality of spring guide columns 545 is installed on the inner wall of the cylindrical slot 53.

[0047] Specifically, when an impact test is required, the electromagnet disc 544 is energized to generate magnetic force. At this time, the electromagnet disc 544 is magnetically connected to the contact side of the impact head 541, and the electric drive telescopic motor 542 drives the telescopic rod 543 to contract, that is, the impact head 541 moves toward the telescopic motor 542 and gradually moves away from the inner wall of the tunnel, causing the spring guide column 545 to be compressed. When one end of the impact head 541 is a certain distance away from the inner wall of the tunnel, the electromagnet disc 544 is no longer energized. Under the restoring force of the spring guide column 545, the impact head 541 instantly moves toward the inner wall of the tunnel, impacting the inner wall of the tunnel. Carry out impact, and let the impact head 541 impact the inner wall of the tunnel multiple times in the same way to complete the impact test. Pulling the telescopic rod 543 to shrink the distance can change the impact force of the impact head 541. After the impact of the impact head 541, pull the telescopic rod 543 to extend it so that the electromagnet disc 544 is energized and re-magnetically connected with the side of the impact head 541. At this time, the extension distance of the telescopic rod 543 can test the impact resistance of the inner wall of the tunnel. The data of pulling the telescopic rod 543 to expand and contract can be transmitted through the Internet of Things, which can indicate the safety status in the tunnel to a certain extent, thereby completing the monitoring of the safety status of the inner wall of the tunnel.

[0048] Working principle: In the unstable position of the tunnel, it is necessary to add reinforced concrete structure to strengthen the strength and rigidity of the tunnel to withstand the stress caused by internal water pressure, geological conditions and other external factors. In order to evenly distribute the stress of the steel bars, it is necessary to set multiple steel bar structures at equal distances, and the multiple steel bars under this installation method can be more evenly distributed inside the concrete to ensure uniform filling during concrete pouring. When the construction workers are in the unstable position of the tunnel, they place the adjustable bracket 4 in the tunnel, and use the adjustable bracket 4 to adjust the monitoring and detection component 1 horizontally to keep the monitoring and detection component 1 horizontal. Then, the horizontal telescopic component 2 is extended by electric drive, that is, the overall length of the horizontal telescopic component 2 increases until it is horizontal. The elastic heads 5 at both ends of the telescopic component 2 are against the two inner walls of the tunnel, thereby stabilizing the position of the monitoring and detection component 1. The overall length data of the horizontal telescopic component 2 is transmitted through the Internet of Things, and the tunnel diameter at the construction location is monitored. After the monitoring and detection component 1 is stabilized, the relative elevation between different points is measured by rotating the construction level 11, which is very important for determining the elevation of the tunnel reinforced concrete construction. After determining the relative elevation between the two points, the length of the steel structure is determined by the height difference between the two places, which effectively speeds up the subsequent reinforced concrete construction efficiency. Subsequently, the mobile component 3 is horizontally moved on the horizontal telescopic component 2. At this time, the adjustable bracket 4 shrinks and no longer supports the ground to change the laser surface emitted by the vertical laser emitter 12. The position ensures that the mobile component 3 moves equidistantly each time, thereby driving the equidistant movement of the laser surface of the vertical laser emitter 12. The steel structure can be equidistantly set according to this laser surface to effectively even out the tunnel stress. At this time, the data of the equidistant movement of the mobile component 3 is transmitted through the Internet of Things, and the reinforced concrete structure data at the tunnel construction position is monitored, which is beneficial to the subsequent tunnel construction project. When an impact test is required, the electromagnet disc 544 is energized to generate magnetic force. At this time, the electromagnet disc 544 is magnetically connected to the contact side of the impact head 541, and the electric drive telescopic motor 542 drives it to pull the telescopic rod 543 to contract, that is, the impact head 541 moves toward the telescopic motor 542, gradually away from the inner wall of the tunnel, causing the spring guide column 545 to move toward the telescopic motor 542, and ... The spring is compressed. When one end of the impact head 541 is a certain distance away from the inner wall of the tunnel, the electromagnet disc 544 is no longer energized. Under the restoring force of the spring guide column 545, the impact head 541 instantly moves toward the inner wall of the tunnel to impact the inner wall of the tunnel. In the same way, the impact head 541 impacts the inner wall of the tunnel multiple times to complete the impact test. Pulling the telescopic rod 543 to shrink the distance can change the impact force of the impact head 541. After the impact of the impact head 541, the telescopic rod 543 is pulled out to energize the electromagnet disc 544 to re-magnetically connect with the side of the impact head 541. At this time, the extension distance of the telescopic rod 543 can test the impact resistance of the inner wall of the tunnel. The data of pulling the telescopic rod 543 to expand and contract can be transmitted through the Internet of Things.To a certain extent, it can indicate the safety status of the tunnel and thus complete the monitoring of the inner wall of the tunnel.
